In this instructable I will walk through all the components and steps required to setup a 3D Printer using the most commonly used RAMPS 1.4 controller board.

Please note that although most components on the 3D printer run 12Volts and less. You do need to connect your power brick to 110 Volts. BE CAREFULL, YOU ARE DEALING WITH LIVE POWER.

There are many other boards on the market and I"ve personally had good luck with the KFB2.0 board with acts almost identical to the RAMPS 1.4 but uses slightly different connectors.

The Type of extruder you purchase is up to you. You can choose from Direct Extrusion (motor on the Extruder) or a Bowden type of extrusion (motor feeds filamant through a tube to Hot-end) but it won"t make a difference in hooking them up.

it was pointed out, some of the pictures show wires directly screwed into components. It best to use fork connectors and ferrules for better connectivity:

The Shield should fit right on top of the Arduino board. The USB port on the Arduino should be on the same side as the Green power connector on the Shield. Make sure that all the pins from the bottom of the shield line up with the connectors on the Arduino. Push both boards snuggly together (this may sting a little)

Before adding the Stepper Drivers you need to decide what type of micro stepping is needed by the 3D Printer. I"m not going explain what exactly it means (there is plenty of articles on that). in general, when you buy a 1.8 deg. step angle (200 steps/revolution), the micro stepping becomes a multiplier. What"s important is that for the RAMPS 1.4 most precise stepping is 1/16th micro stepping (16 x 200 = 3200 steps/rotation).

In order to instruct the hardware to use 1/16th micro stepping, jumpers are added between the banks in which the stepper drivers will fit. For 1/16th stepping you need to add three jumpers under each driver. Make sure they are on straight, it"s easy to plunge one of these past the actual pin.

VERY IMPORTANT!! Note how the drivers A4988 Stepper drivers above have a little potentiometer on top (this little phillips screw). When inserting your stepper Driver MAKE SURE THE POTENTIOMETER POINTS AWAY FROM THE BOARDS POWER END (GREEN CONNECTOR).

If you are still unsure: Find a labeled pin on one or more corners of the stepper driver board (DIR, GND, ENABLE, VMOT) and match it up to the RAMPS pinouts.

I hate to say this but, sometimes you"ll find that the bays for these stepper drivers are too close, or the edges of your stepper driver are a bit too wide. In the image above you can see a gap between the top two drivers, whereas the bottom ones barely fit. It might make for a very tight fit and in cases where it doesn"t fit, you may have to file some of the edges from the stepper driver.

It"s a bit hard to see on the smart Adapter I have here, but but you can kind of make out that the left connector (10 pins) says EXP2 and the right connector says EXP1. These correspond with the EXP1 and EXP2 connectors on the LCD board

power comes in on two tracks into the Ramps 1.4 shield. One track is 12V 5A which powers the board and motors, the second track is 12V 11A which powers the heated elements like the extruder and heated bed.

Connect the wires as seen in the images. Be careful, as you can see, the 110V live wire is exposed. Unplug your power source prior to lifting the lid accessing the screws.

Also, note that when you plug in the RAMPS 1.4 with a USB cable to your computer the LCD will come one and you can program the Arduino that way. There is no power to run any motors or heating elements though. For that, you do need the external power source.

Stepper motors come in many varieties and with different power specifications. The printer built in the previous instructable uses Nema 17 0.4Amp Stepper motors. These aren"t the strongest steppers but they do just fine. My CoreXY printer that can handle more speed/torque runs 2.0Amp stepper motors.

Generally the Nema 17 Stepper motors and associated cables are configured correctly, so when you plug them in, they"ll run at first try. If your stepper motor is making funky jumps or just shakes, it generally means the wires from the motor don"t line up with the 2B 2A 1A 1B pins on the board.

If that happens you"ll need to closely look at the data sheet that generally is shown when you purchase the steppers (or it will say something like Black(A+), Green(A-), Red(B+), Blue(B-)). Granted when the wires don"t line up it can be a bit of a puzzle trying to figure out the proper combination.

If you"re building a Prusa/RepRap type printer, you"ll employ 2 stepper motors for the Z-Axis. The RAMPS 1.4 shield has accounted for this and offers two rows of connection pins for the Z-Axis.

Nowadays you can buy really fancy stepper drivers that feel resistance. Along with Marlin software changes you can do without end stops. In most printers though, you"ll need end stops to make sure your X/Y and Z axis don"t run off the rail (or worse; tear something of your printer apart).

The RAMPS 1.4 comes with 6 end stop connections (X Min, X Max, Y Min, Y Max, Z Min, Z Max). Rarely do you use all six. What you"re really interested in is either the Max or Min. If you know one, you can limit movement based on it"s location (0) via the software (if I can detect Min and know my bed is only 200mm wide then I can tell the software to not move beyond min+200)

The most common types of end stops are mechanical swithes, optical switches and proximity sensors. Proximity Sensors tend to only be used for the Z-Axis in conjunction with Auto Bed Leveling. I won"t cover inductive sensor wiring here but if you"re interested, I did write something on the wiring in this article Proximity-Sensor-Detection LJ12A3-4-Z-BX vs LJ12A3-4-Z/BY wiring

If you are using the most commonly used end stops "Makerbot Designed Mechanical Endstop Kit", it comes with little circuit board and wiring. It will light up an LED when triggered.

There are 3 wires coming from the end stop: RED/BLACK/GREEN IMPORTANT: make sure the wires correspond with the image above. If you turn around the connector on the RAMPS board and accidentally put the RED wire on the Signal (as opposed to +) YOU WILL SMELL SMOKE real fast.

If you forego the fancy Makerbot Switch (don"t do it for the price, it"s generally more about the size of the sensor) and instead go with a micro switch it"s my experience wiring is a bit easier. You really only need two wires. solder the wire to the two outside pins of the Micro switch and connect them to the -(minus) and s (signal) pin on the ramps.

You can test the micro switches and their behavior by opening an application like Pronterface or Octo Print and sending the g-code m119. It will show the state of all end stops. As seen in the video below.

The Extruder (the hot-end that spits out the plastic) generally has 6 wires associated and possibly more if you you use auto bed leveling and an additional Hot-end Cooling fan (Unlike the Heat sink fan, it cools the last layer of deposited plastic).

The normal wiring setup generally means we hook the heat sink cooling fan to the 12V fan connector on the RAMPS 1.4. These fan pins can be found between the fuses and the X Stepper Driver (see image above). On the image the left pin is + so make sure the red wire from the fan connects to that one. Oh, and for some reason all wires on 3D printers seem to come at 1 meter but the cooling fan wires generally never do. Be prepared to extend them.

The RAMPS Board has 3 Thermistor hookups (2 extruders, 1 heated bed). The Thermistor wire for the extruder (The white skinny wires) go on T0. Polarity does not matter.

Most heated bed you buy will come with wires and thermistor but are often not yet connected. The most common heated bed is the one seen in the image (the MK 2B by Joseph Prusa, or most likely some clone of it).

At the bottom of the bed you"ll generally see either two or three metal connectors to which to solder the power. If your printer is 12V follow the instructions and solder one wire to both 2 and 3 and the second wire to 1. Don"t bother with the LED connection, There really is no point to those.

The glass bead head of the thermistor goes right into the tiny hole at the center of the bed (this so it will close up to the material on top (like a glass plate).

There you have it. All the wiring that was done for the Laminated 3D printer. These instructions are pretty much the same of any other RAMPS 1.4 installation. There are additional options such as Hotend Cooling fan and Auto Bed Leveling (both of which can be done with the standard RAMPS 1.4) but I"ll save those for another instructable.

The only jumpers you really care about are the jumpers that will be under the stepper drivers. if you fill the three rows under each stepper driver you will use, it will set the micro stepping to the highest (1/16th on the A4988). each jumper oriented shield to shield (see ramps image below). Microstepping options in other image

Do you change the default value of the potentiometer in the stepper driver or do you let it be? I have a 2.6 V 1.2 A NEMA 17 Stepper motor but I am not sure what the current and voltage value on the stepper driver should be to get the best result.

You may have to end up tweaking it when running. I have mine at about 0.6v (If I remember correctly. You can change the pot meter when running the motor and kind of go by sound. If you want to do it right: https://youtu.be/OpaUwWouyE00

I searched more and figured out that there is not a universal standard for colors and letters. I used a multimeter to find out which wire is for what coil inside the motor.

Hi, I’m trying to use this setup for a robotics project, how would I include sensors to trigger motors on the 2560 if the ramps has used all the pins? Do I run a master/slave setup

How do you wire up a 3-wire endstop (makerbot) as a runout sensor? I know you have to use one of the servo ports but I don"t know which one and what wire goes where.

Can I use a MKS base board, v1.6 and control the printing action using Octoprint which will loaded on rasperby pi, instead of using the RAMPS kit ? and i was wondering how can i callibrate or it ? or if you have a guide to use step up the printer using MKS-BASE ?

I"m not familiar with the MKS 1.6 but when I started out with my KFB 2.0 board it"s closed "pin output" pal was the "MKS gen L". Wiring the KFB2.0 3D Printer Controller : 11 Steps (with Pictures) - Instructables Check it out and I think you"ll find the layout and setup very similar.

As for calibration; that will be independent of board and all configuration in the Marlin Software. Check out my other instructable starting at step 10: 3D Printer Cantilever 2.0 C3Dt/c : 14 Steps (with Pictures) - Instructables There"s also videos associated that walk you through some of the steps.

Hi, i have a question. My arduino mega works fine but when i fit the Ramps 1.4 board to it and plug it into my computer the leds on the mega board do not come on nor does my computer acknowledge it either aubily or on device manager. If i take the ramps board off the mega is recognised. Am i right in assuming the ramps board is faulty?

that hasn"t happened to me so I can"t be certain. Certainly doesn"t sound right. Here"s a link with what sounds like an issue similar to yours (with some things to try) https://www.reddit.com/r/3Dprinting/comments/39mzvb/help_ramps_board_makes_arduino_stop_working/0

The power source in this printer actually uses (ring connectors) and the power unit is covered but, you are correct. This was the very first printer I built (over 5 years ago) when forks and ferrules were barely on the radar. All my subsequent printer designs here use forks and ferrules.

I"ve installed Marlin on my Arduino board, no issue. Installed the jumpers and drivers to the Ramps 1.4 board, plugged the Ramps into the Arduino, added the LCD adapter board and connected the LCD screen. Plug it into the computer with the USB cable and voila, she fires up great, ready to go. Unplug the USB and connect the Ramps board to my 12VDC power supply + to +, - to -, and *nothing*. My VOM is showing 12.1 volts at the connectors on the Ramps board, but no LED"s on the boards light up and the display screen doesn"t work. Unhook the power supply, reconnect the Ramps to the computer with the USB cable and it comes back to life. What gives? I"ve triple-checked every connection and it all matches documentation in this instructable. Am I right in thinking I got a bad Ramps board?More CommentsPost Comment

In RAMPS 1.4 the capacitors and resistors are now surface mount (SMD) components. This provided more space for more passive components, as well as headers. This does add another set of steps to the assembly process, but we stuck with larger sizes to make it fairly painless.

There are multiple boards all based on the RAMPS 1.3/1.4 design with minor variations in form factors and components, for example Prusa, Ultimaker and others. Other incarnations combined the components of the Arduino ATmega and the RAMPS into a single board, some using ATMega128. They may have different power/rating capabilities but the basic structure and electrical behavior is very similar and we describe them as RAMPS compatible, in fact most boards in firmwares like Marlin are treated as derivate of RAMPS.

This section presents the basic steps to wire an assemble RAMPS 1.4 board assuming the more common scenarios. Check the #Assembly section to learn how to assemble your own Ramps 1.4 board.

Notice that the bed thermistor connects to a header block of three pairs. From left to right they are labeled T0 for the first extruder, T1 for the heatbed, and T2 for a second extruder.

The extruder has a heating element (heater cartridge) in the heating block that connects to the screw terminal labeled D10. The heating element must be 12V and consume an average of 2.5 amps. The temperature of the extruder is monitored by a thermistor also installed in the heat block. The thermistor is connected in the terminal labeled T0 (uses pin A15 in Arduino). (The thermistor does not have a polarity.)

The endstops are the switches that tell the firmware when one of its axis (X, Y, Z) has reached either (or both) its minimum or maximum limit. In the board you will find six 3 pin connectors labeled (from left to right) X-MIN, X-MAX, Y-MIN, Y-MAX, Z-MIN, and Z-MAX. While you may connect both endstops for an axis the common setup is to use only one per axis. (Note firmwares implements software endstops for the opposite side using the dimensions on the build area of the printer.)

To simplify the setup of the firmware it is easier to only use the minimum pins of each axis. The minimum is also know as the home location of your axis, on our traditional cartesian FDM printers we said that the end stop for the Z axis is in the bottom end of the frame, for the X axis is to the left of the frame and for the Y axis is somewhere near the back. (Note: all of this can be configured at will but requires more changes in the firmware. Check this excellent page explaining endstops from the Marlin Firmware guys.)

You have endstops with 3-pin connectors. Now days when shopping online is very common to find 3-pins endstops with leds, mainly due to all the Ender 3, CR-10 and similar clones that use them.

Is also common to find endstops with 2-pin connector or using only 2-wires (even if the connector has 3-pins). This is also the case when you wire your endstops directly, in which case only the COMMON and NC pins of the switch are used.

From top-to bottom you will notice that for each axis the first pin is the Signal S, the second is GND, and lastly the 5V pin. In a two pin connection the + pin is NOT used.

When wiring a 2-pin endstop the NC pin is connected to GND (-) on the board. The COMMON pin (marked as C or S) is connected to the S on the board. Usually the endstop will have their pins identified.

When wiring a 3-pin endstop is best not to make assumptions about the pinout on the endstop, check for markings on the PCB, read the manufacture"s information or use a multimeter to identify the pins.

Once you have figure out the type of endstops all that is left to do is to plug the corresponding connector for each axis using minimum pins in the board.

The board allows up to 5 independent motors using stepper motor drivers which today is mainly drivers using the board design of Pololu like the A4988, the DRV8825 or even TMC2130.

Before installing the driver you need to set up the jumpers corresponding to each stepper to set the steps. These jumpers define the microsteps for that particular driver. For A4988 setting all the jumpers will set the micro stepping to 1/16 of a step. For a DRV8825 setting the last jumper will enable 1/16 micro stepping.

Some notes on TMC2130: Getting TMC2130 stepper drivers to work on a RAMPS 1.4 board requires modifications to the board. TMC2130 stepper drivers are configure by software using SPI. TMC2130 drivers require the pins from AUX02 and AUX-3 to be available if for example you have an SD Card or and LCD, chances are that you won"t be able to setup the SPI interface for the TMC2130.

A RAMPS 1.4 board using traditional Pololu drivers provide from 1A to 1.2A of current and about 4V to a NEMA motor. The force a motor can produce is mainly measure by its holding torque (For example 3.2 kg-cm, You will also find this in Newtons or oz-in)

The force it can produce. The main metrics for this is the holding torque (For example 3.2 kg-cm, You will also find this in Newtons or oz-in). For most designs an average of 44 N·cm is enough force to handle your everyday prints.

The steps of a motor is how accurately it can move. This is given in degrees per step or steps per revolution. For example in 3D printing an average NEMA17 motor used is 1.8 or 0.9 degrees with 200/400 steps per revolution. If a motor makes a 1.8 degree rotation in one step, then to complete one revolution (that is 360 degrees in a circle) it will take 200 steps. Most common NEMA 17 motors are 1.8 degree steppers.

A motor will have 4 cables either directly attached or as a ribbon that has a (JST-XH) six pin connector in the motor. The other end of the connector will be a 4 pin header that attaches to the RAMPS board. (From the six pins of a motor only four are used on the connector.)

Since the motor has two coils (2 phases motors), each coil has two pairs of cables. Like shown on the above picture the trick is to identify what pin in the motor corresponds to a pair. The illustration shows two common combinations, we call them straight and cross. The straight has the pins for the coil in order and the cross switches the two in the middle.

The other thing with the two cables in a pair is their polarity. The polarity tells the direction of the spin. There is not such thing as wrong direction instead the direction is dictated by how is the motor used and the control board. For this reason in many motor diagrams you will NOT see polarity specified as is left for the implementation of the design to select the default direction.

Using a multimeter in continuity (resistance/diode test mode) you can test the combinations of pins until you find the pair that belongs to one coil. In continuity test you will have a low resistance value, some multimeters beep or read "short/closed" to indicate when you found a pair. Use the first picture as reference to check if you have a straight or crossed pinout.

Hint If you are swapping a motor in a printer or equipment already wired, then check both ends to see which are the pairs, use the picture "Common Coil Combinations" for reference. If your new motor came with a cable then compare the motor end of the new and old connector to quickly tell if its cross or straight. Usually black/green are in one side and blue/red in the other (don"t mind the order of the pairs), if you see one cable from one of these two pairs swap in the middle two pins, chances is that you have a crossed connector for your motor.

Connect the 12V power cables to the positive end (+) on the board. In your Power Supply (PSU) these cables may be yellow or red and are usually labeled V+ or 12V. The black cable is negative/ground and is usually labeled V- or COM. Always check the label on the power supply for actual cable details or see the manufacturer"s manual.

The board has two pairs of connectors for power, one labeled 11A and the other 5A, both of these pairs are 12V connections. The 11 amps pair is used to power the heated bed. The 5 amps source is used to power the board, the rest of the printer"s components and the Arduino board.

Your power supply should be able to deliver 16 amps, is ok if it delivers more. The generic S360-12 power supply is commonly used in 3D printers and provide about 30A/360W. Other variants are the S-480 and S-600 for 480W and 600W respectively.

The heater block on the extruder shares the 5A source, make sure that the amperage/current drawn by additional extruders can be supported by the board.

The RAMPS 1.4 has a 1N4004 diode labeled D1 which allows 12V to feed and power the Arduino Mega 2560 board. This diode is installed in most pre-assemble boards, thus the Arduino board is powered by the Ramps by default.

When the RAMPS is not powered or if the diode is not installed or cut/removed, the Arduino gets its power from USB or a power supply connected to its 2.1mm (center positive) power jack.

The Arduino provides a Vin connection to connect an external power source that can be from 7V to 12V, remember the diode D1 can not be connected if you plan to power the Arduino using its Vin.

The PS_ON pin is intended to switch your power supply on and off. Many firmwares support pulling this pin low with M80 command to turn the power supply on, and M81 to turn it off. This behavior is desired for ATX power supplies and can be modified in firmware to support 5V high power supplies like those borrowed from an Xbox.

If you want to use PS_ON to turn on your power supply then don"t use diode D1, you need your Arduino to be powered from 5Vsb otherwise when no USB is connected the PS_ON pin floats (and your power supply pulses on and off).

Or you can hack up a 12V laptop power supply, or other 12 V "wall wart" power supply. Make sure that the power supply can output 5A or greater. Additional 11A may be needed for heated bed support.

The 5V pin in that connector on RAMPS only supplies the 5V to the auxiliary servo connectors. It is designed so that you can jumper it to the VCC pin and use the Arduino"s power supply to supply 5V for extra servos if you are only powered from USB or 5V. Since there is not a lot of extra power from the Arduino"s power supply you can connect it directly to your 5V power supply if you have one. You can also leave this pin not connected if you have no plan to add extra servos.

First, the 1N4004 diode (Diode D1) connects the RAMPS input voltage to the Arduino Mega which has a recommended maximum input voltage of 12 volts. If your board does not have this diode soldered in (or if you cut it), you will need to power the Mega through the USB connector or through a separate 5v line, but this allows a higher RAMPS voltage.

Second, most boards use 25v or 35v aluminum electrolytic capacitors (C2, C3, C4, C6, C7, C9, and C10). To be safe, you should only go to half of your rated maximum voltage -- thus if your board has 35v capacitors (code VZA) then you should use a maximum input of 17.5v. The absolute maximum voltage is determined by the Pololu servo drivers, which themselves are limited to 35V.

DON"T secure Arduino/RAMPS with conductive screws through both mounting holes. The screw may cut into the positive trace creating a HIGH current short.

On R1+ board the extruder heater is connected to the plug labeled D9. This connector corresponds to the original D10 of RAMPS board and still responds to Arduino"s pin 10.

As of 2012 Marlin has built-in support for RAMPS 1.3 and Ramps 1.4 boards. Marlin"s Firmware up to version 1.1.9 and even version 2 compile with ease using new version of the Arduinos IDE. Compiling a firmware older than 1.1.x require changes to the code or to use an older IDE version.

The SRAMP Firmware is a fork of Marlin v1.1.9 exclusively tailored Mendel/Cartesian printers using 8Bit Microcontrollers. The firmware sports a new GCODE parser and aims to make it easier hobby builders to add features (LCD, SD, etc).

Working preconfigured Sprinter firmware can be downloaded here: File:UltiMachineRAMPS1-4Sprinter.zip. Mechanical is in the folder ending with ME, optical endstop firmware is in the folder ending in OE.

mechanical endstops (now the default ultimachine.com option) require #define OPTO_PULLUPS_INTERNAL 1 to be added to configuration.h if not there by default.

Note * You can use Female Headers which are not the exact size, but they are hard to break/cut so in this case buy some extra! (one wasted header per cut)

A BOM for sourcing the RAMPS components from Mouser is also available in this google spreadsheet (This list is incomplete and has missing or incorrect quantities.)

The surface mount can be done a few ways. Since all the SMT components on this board are large 2 pad parts you can do pin by pin soldering pretty easy with normal soldering equipment. Start by putting a small amount of solder on one pad. If you have flux, coat the soldered pad. Use the tweezers to hold the component down in position and heat the solder to tack the component into place (make sure the entire solder blob flows so you don"t get a cold solder). Then solder the other pad. Also popular is using solder paste for pad by pad soldering, Oven Reflow (need link), and HotplateReflowTechnique

These must be placed in the proper orientation. The board has the foot print of the components printed on it. The rounded corners on the base of the capacitor must line up with the white print on the PCB.

These must be placed in the proper orientation. The board has the foot print of the components printed on it. The rounded corners on the base of the capacitor must line up with the white print on the PCB.

Solder 1 1x6, 6 1x4, and 7 2x3 pin headers on top of the board. The long post should be standing up to take a connector. Solder one leg on each one to tack them into place. Then re-heat the joint and push on the component until it is perfectly situated. Then you"ll want to solder the rest of the leads. You will get burnt if you touch the other side of the pin you are soldering.

Place the female headers for the stepper drivers on top of the board. You can use the 1x8 and 1x6 pin headers to jig them straight. Turn the board over and solder these pins.

This section assumes you are using Pololu, but there are other options. Insert two 1x8 pin headers into the board. If you bought a kit with one 16 pin header, simply cut it so that you have two 1x8. Make sure that the side with the labels has the long ends of the posts, and the side you want to solder is the side with the heat sink. Doing this backwards will cause you not to see the labels and will most likely not fit. Remember to apply a heat-sink to the largest chip on the back.

D1 should only be installed if the 5A rail is powered by 12V. It can be omitted and the Arduino will be powered from USB. You will want D1 installed if you add components to print without a PC. To reiterate, D1 MUST be omitted if you are powering the 5A rail by more than 12V, or the power is not absolutely clean, otherwise you may damage your ramps.

This is the smaller yellow fuse. This can be placed in any orientation. When soldering the fuses it is best to use a piece of 3mm filament or something similar to keep the ceramic coating on the pins from blocking proper solder along the through hole.

Since the fuses are the tallest parts, it is simpler and more convenient to solder them last. From this point on, solder the rest of the RAMPS in order of bottom pins, reset switch, terminals, mosfets and then fuses.

Place these on the bottom of the board with the long post out to plug into the Arduino MEGA. You can plug them into the MEGA to hold them in place while you solder. Do not overheat the pins while in Arduino or you may damage its connectors.

This must be oriented where the wire holes are turned towards the edge of the board. Solder a pin on each end and make sure the component is flat on the board and solder the middle pins.

Connect Motors (Do not disconnect or connect motors while powered; if the connection is loose, this will cause the motors to misbehave and possibly kill your stepper driver.)

As there are (by 2019) many different producers of the RAMPS 1.4 board, some who have made their own changes to the design files, thus some boards have some close to critical issues. See examples below.

A "thermals" design flaw has been noted in the RAMPS 1.4 Eagle CAD files. This has been confirmed by visual inspection of production boards, which consistently shows only between two and three (almost never four) thermal-isolating traces per side of the PCB, to power-carrying pins, of under a 0.5 amp carrying-capacity per trace, assuming a 1oz copper thickness.

This image is also in error (it isn"t: it"s a photograph of an existing production RAMPS 1.4 board), the left two unpopulated pins on the image are for the always on fan and use very little current. So are not an issue (actually it is)

The problem may be fixed in the Eagle CAD files - for a future version of RAMPS only - by disabling "thermals" on the GND, +12V and the +12V2 Copper pour. However on existing (mass-produced) RAMPS 1.4 boards, estimating the total widths (including all thermals from all tracks on both sides of the PCB) checking with an online copper width calculator and adding up the total current, assuming a 1oz copper PCB the maximum safe current on the fuses (giving only a 10C rise in temperature of the thermal-isolation tracks) is only around 6 (six) amps and in other areas the maximum safe current (assuming the same 10C rise in temperature) is around 8 (eight) amps.

This problem may potentially be fixed on existing RAMPS 1.4 boards by augmenting the power traces with suitably-thick insulated wires with sufficient current-carrying capacity, soldering them to all the relevant pins.

Minimum total parallel trace with measured on the bed power rail was about 80mil, which would equate to a 4 amp safe limit using the above considerations. Board is marked with "www.bigtee-tech.com" where the "UltiMachine" and "reprap.org/wiki/RAMPS_1.4" markings are in the original 1.4 design.

Note the decreased isolation of the copper pours. Slikscren has the "reprap.org/wiki/RAMPS_1.4" marking but not the "UltiMachine" found on the original design.

Using a "JY-MCU" (vendor Shenzhen Jiayuan Electronic Co.,Ltd.) Bluetooth modules (HC03, HC05, HC06 chipsets) to setup a wireless connection to the Arduino.

Before the module can be used, the default setting has to be changed. You can connect to and modify the BT JY-MCU module settings via the Arduino mega 2560 using the pin 10 and pin 9 as Rx and Tx terminals, respectively. Make sure you connect Rx on the BT module to the Tx on the arduino and vice versa, in other words Rx goes to Tx and vice versa. Upload the simple code to arduino located on an instructable entitled "Success-Using-the-JY-MCU-linvor-Bluetooth-Module". Use the serial monitor within arduino IDE or another terminal program, with baudrate set to 9600 and "No Line Ending" selected, enter the following commands:

Alternatively, you can connect to the module from PC via USB<->RS232 (RxD/TxD) interface with default settings (9600, N, 8, 1). The module shouldn"t be paired at that moment. Use the same AT commands as above.

On RAMPS/Arduino Mega the UART level are 5V but the BT module supports only 3.3V input. Therefore the TxD level has to be divided by resistor. This passive solution is fast enough for 115kBaud. Overall only 4 wires have to be soldered.

Please follow steps 4 and 5 on our Trouble Shooting page. There are also many online resources regarding the CH340 driver on various operating systems; a simple google search is a good place to start. Contact us if you need further assistance.

Please Note: the firmware supplied here may not be compatible with the newest Arduino IDE. It is generally suggested to use the classic 1.0.6 version IDE.

Mount the RAMPS 1.4 Board onto the Mega 2560 board. The headers and pins on each board may need some adjustments to align properly. If it doesn"t fit, don"t force it! You may damage the headers or pins.

Further tests may be done even without heat bed or extruder connected. Connect 12V power and double check the polarity. Set the heatbed and extruder temperatures to 110 and 230 °C, respectively. Two LEDs on the RAMPS board will be turned on indicating the power outputs are working. Then turn off the heat bed and extruder power.

If your kit came with a LCD smart controller, the hardware installation process is fairly simple. Connect AUX, EXP1, EXP2 to RAMPS via the supplied adapter and ribbon cable. Every smart controller is tested before shipping. In the event yours is not working, please reset the smart controller and double check the connection. You may need to swap the ribbon cables.

I"m working on a Laser cutter. I’m using the RAMPS 1.4 and Marlin software. To make the Marlin software work with a laser I’m inspired by this blog from dreammakercnc: Marlin Firmware modification for Laser Control

My plan is to use Inkscape to design and create the G-code. With Pronterface I will sent it to the laser cutter. My plan is to get the Marlin software to work like in this video:

I"m using stepper motors. They are working when I connect to Pronterface. I can control the motors when I"m using Pronterface. But when I load a G-code file, that I designed with Inkscape, the program seems to freeze. Nothing happens. It"s saying:

I haven"t connected any extruders, fan or bed to the RAMPS 1.4. I have connected one thermistor and one endstop. Both are working well. When I upload the Marlin software there are no problems.

Hello everybody i’ve just built my first polograph machine followign this instructable https://www.instructables.com/id/Polargraph-Drawbot/ using the ramps 1.4 i’ve just uploaded the firmware to the board and i can controll it with the makelangelo software but the problem is that when i plug the lcd it dosen’t work i just get a blue screen and i’ve uploaded the same firrware as the instructable i have a reprap 12864 lcd does anyobdy knows how i can solve this problem thanks and i’m a beginner on this like said i’ve just finished building it today

I have modified code to use interrupts for 12864 LCD and RAMPS 1.4. Encoder works nicely now. How do I submit it for a PR so you can review it? I can’t push a new branch to the github repo.

did you branch from the main repository? You should be able to submit a PR with either github desktop or through the github website. I haven’t contributed to many other projects so I’m not confident enough to guide you. Come to our Discord if you need more help or to chat live about development. https://www.marginallyclever.com/channels/

Which LCD are you using? When I turn my dial, nothing updates on the screen. I have to mess with it for a couple minutes for it to finally move a little bit. Also It would seem the SD card pins are incorrect as well for my LCD. I can detect my SD card using a different arduino program with the following code, im not sure how to adopt it for makelangelo.

From the code you posted it looks like chip select is pin 53 (matches board_ramps.h) and sd card detect is 48 (board_ramps.h has 49 as the default). Look for

At the top of your code there’s an “const int chipSelect = 53;” and later the number 53 is used many times instead of the word chipSelect, which is the point of having chipSelect. in I would use a

and then use the world CHIP_SELECT instead of ’53’ where appropriate. The pre-processing step of the compiler will replace the word with the equivalent number. it’s probably better than ‘const int’ because a const int might take up some ram if the compiler is dumb, and ram in an arduino is in short supply. also if it actually takes up ram then the firmware has to look up that number every time it is used, which is slower than having the number hard coded on hand ready to go.

I know how to use git, but not really familiar with github. That said, I found instructions on stackoverflow about how to use github. Seems they want me to make a forked repo instead of just branching in your repo. I believe the pull request has been made. Here’s the steps I found…

I had started from your Dec 23 commit with hash ca06a9ca702, but the repo was updated today, so I had to merge my changes into that. A fix for the “print from file” menu that I made today (lcd_dirty flag usage) that is unrelated to the encoder interrupts unfortunately got committed with it when I merged the code. The commit message explains what I did, and I’ll quote it below too.

Tylor, I’m using a 12864 LCD and RAMPS 1.4 and ran into the same issue where the knob/menus were unusable. So the first thing I did was fix that so I could explore the menus.

Yes, the “modified to the code to work with interrupts” requires some changes that would be a bit extensive to list here… and there some jumpers that would be needed too. Dan is concerned about using the interrupts and what affect that could have on motor control. I believe I could point you to the github fork I made, but probably worth waiting for Dan to look it over first since he knows the code base.

Provided some responses in the PR, and put a picture to show the jumpers I had to do. Let me know your thoughts about the stepper motor and servo verse interrupts, and if something different is warranted (e.g. disabling the knob interrupts during time critical sections).

Dan, pushed changes to use abs() when turning the knob quickly per your PR comment. Also fixed some code that could overwrite and corrupt memory, made long M117 messages wrap on the 128×64 display so they can be read, and fixed a display location calculation error that made the 128×64’s left most column not get used. Those changes are pushed to my fork in github and can be viewed in the PR.

We used to have a lot of ramps controller die by having their regulator die. If you can still flash it, try powering the usb with a cheap phone charger. If the regulator died in a way that it is just open, that should be ok. I can imagine it died in a short, in which case, the 12V and 5V rails may be shorted

You definitely can kill the 5V reg by shorting the (+) and (-) pins of an endstop. You can also just breathe on them. They are replacing the right parts with cheap knock offs to reach the $5 price point. This is why Ryan switched to the rambo. He used to charge like $60 for the ramps combo, which included flashing them, testing them, and refunding broken ones, but it still wasn’t worth it, considering how many were DOA or returned after some minor mistake.
