ramps 1.4 lcd touch screen manufacturer

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.

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)

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.)

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 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.

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.

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.)

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.

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.

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.

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.

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.

The results were not as I expected. On the RAMPS pins 2 and 10 showed 5v. I have one ribbon lead that has a connector at 180 degrees. I tried it, and sure enough the LCD lit, thought it only showed solid character blocks. I then removed the pin shrouds from the pins of the LCD so that I could reverse both connections there. It lit, but still nothing displayed. My RAMPS and 2004LCD come from the same source and are clearly configured differently to the 2004LCD"s that the SKR 1.4 Turbo support. Turning the connectors through 180 was not a fix, so I have no idea what the correct pin configuration is that I could change either physically, or in firmware.

After all the head scratching and time wasted, I have decided that your suggestion of a touch screen is the best solution. I have decided to purchace a BTT TFT. That will be compatible with my BTT board I hope!

This Smart Controller contains a SD Card reader an rotary encoder and a 128x64 LCD display You can easy connect it to your Ramps board using the smart adapter After connecting this panel to your Ramps you don t need your pc any more the Smart Controller supplies power for your SD card Further more all actions like calibration axes movements can be done by just using the rotary encoder on the Smart Controller Print your 3D designs without PC just with a g code design stored on the SD card

The LCD screen is vital for operating the printer. Should you encounter any kind of trouble, such as a dead screen, corrupted text, or other issues, please refer to the guide below.

First of all, unscrew the LCD screen from the printer frame, remove both M3x10 screw holding it the LCD board in the plastic casing, and remove it from the casing. See if the problem still appears when the LCD is not pressed by the casing.

Firmware updates are necessary to keep your printer up to date. However, the installation of incorrect firmware can lead to letter corruption on the LCD screen. There"s an easy fix, though:

There is a small chance the printer"s LCD screen can glitch out by electrostatic discharge when inserting the SD card. Try to turn the printer off and on again.

This problem usually appears only on user-assembled printers. If your printer"s LCD screen remains blank or displays corrupted symbols after you turn on the printer, there is a chance it is caused by incorrect wiring. Follow these steps to fix the issue.

If you suspect that the LCD ribbon cables connectors are not firmly seated in the slots, disconnect the LCD ribbon cables and check the slots for any bent pins. If there are bent pins, you can use tweezers to fix them. However, be very careful not to break the pin(s) completely.
