duet lcd panel manufacturer

The PanelDue is a full-color touch-sensitive graphical control panel from Duet3D. Although primarily intended for use with Duet electronics, it also works with other 3D printer electronics that supports a true serial port and includes the required support in the firmware, for example RADDS. Both RepRapFirmware and Repetier firmware support PanelDue.

Note that the Duet 3 6HC does not have a 10 pin LCD/SD connector, so you must use the 4 pin cable for connecting a PanelDue if using with a Duet 3 6HC.

The PanelDue displays run off 5V power from the host 3D printer controller. Uses a 2-wire async serial interface with 3.3V signal level (5V tolerant input).

There are two cable options for connecting the PanelDue, both options are included with the PanelDue V3 kit. Option 1 is the included 4-wire cable with Molex KK connector ends. Option 2 is the included 10-wire ribbon cable. For some boards, both cables need to be plugged in to enable both TFT panel and SD card socket.

The length of the 4-way cable is not critical, however the resistance per conductor should not exceed 0.1 ohm. The SD card socket on the TFT panel will not be functional. The cables supplied by Escher3D and Duet3D are about 800mm long. There have been reports of cables up to 1500mm long being successfully used. Take care to route the cable away from motor and endstop cables. Twisting the cables may help prevent cross talk interference.

A PanelDue can be connected to connector IO_0 using a 4-core cable wired like the one shown in the images below. The 4-wire cable supplied with the PanelDue has a 4-way Molex KK connecter on each end, but is supplied with a 5-way Molex KK connector for use with Duet 3. You will need to rewire one end. The 4-wire cable does not allow access to the SD card socket on the PanelDue.

Older versions of the Duet 2 WiFi/Ethernet need both the 4-wire and ribbon cable to be plugged in to use the TFT Panel and the SD card socket, when connecting PanelDue v2.0 or v3.0.

Use a 4-core cable terminated in a Molex KK or compatible connector at the PanelDue end and a 2x4 Dupont-style connector at the Duet end. This plugs into the end of the expansion connector. See https://miscsolutions.wordpress.com/pane....

In order to use the SD card slot on the PanelDue, you must use the ribbon cable option. If you do not wish to use the SD card slot, it"s recommended to use the 4-wire cable option described in Option 1.

The Duet 3 MB6HC has no PanelDue_SD socket. To use the external SD card, it requires RRF 3.4 or later, and a special wiring scheme; see "Duet 3 MB6HC using ribbon cable" section below.

Connect a 10-way ribbon cable between socket X5 on the PanelDue and socket CONN_SD (Duet 2) or PanelDue_SD (Duet 3). The connector is a standard 10 pin 2 row 2.54mm pitch box connector that accepts IDC connectors for 1.27mm ribbon cable.

Caution: if you are using a thermocouple and/or PT100 daughter board, the use of long ribbon cables between the Duet and PanelDue may affect communication between the Duet and the daughter boards, because the ribbon cable connection to the SD card on PanelDue uses the same SPI bus as the daughter boards.

Although the Duet 3 MB6HC does not have a connector for the PanelDue ribbon cable, if access to the SD card on PanelDue is required then this is possible using a special wiring arrangement. You must use RepRapFirmware 3.4 or later, and you must enable the external SD card using this command:

Note: if you are using an older version of either PanelDue 7i or PanelDue 5i, or a non-integrated version of PanelDue, then those do not support the CD signal. In that case you should omit the second port, for example:

The card detect signal (CD) is used to tell the Duet whether a card is inserted or not. Non-integrated versions of PanelDue (V2, V3) and older versions of PanelDue 5i and 7i (v1.0 of the 5i and v2.0 of the 7i) do not provide a card detect signal.

Duet 2 boards do not support the card detect signal on the external SD card, so can never tell whether a card is inserted or not except by trying to read it, and can"t detect a card being removed. No modifications are required connected older or newer PanelDue, or other external SD card adapters, to Duet 2 boards.

Duet 3 boards do support the card detect signal. Newer versions of the PanelDue 5i and 7i (v1.01 and later of the 5i and v2.01 and later of the 7i) provide this signal.

However, if you use a non-integrated versions of PanelDue or older versions of PanelDue 5i and 7i with Duet 3, it is necessary to ground the card detect signal, or the firmware will permanently think no card is inserted. There are a number of ways to achieve this.

This mod will enable the card detect signal. See the pictures below showing how to modify a PanelDue 5i v1.0. Connect a wire (thin enamelled copper in this instance) from the SD card socket Card Detect pin to the appropriate pin on the ribbon cable connector.

On the Duet 3 Mini 5+ you can ground the card detect signal by bridging pins 2 and 4 of the EXP2 connector as shown here. The firmware will see the SD card as always being present.

Generally it is best to run the latest version of the PanelDue firmware that is supported by the RepRapFirmware version on your Duet mainboard. See: Installing and Updating PanelDue Firmware

From RRF v3.2, PanelDue firmware releases are co-ordinated with the RRF release, and share the same version number. Use the PanelDue firmware version that matches your Duet mainboard"s firmware version.

PanelDue will display the bed heater H0 first (even if it is disabled), then iterate the defined tools. It then iterates the defined heaters below this. It expects a 1:1 relationship between tools and heaters. This means:if you have a machine that uses one heater for more than one tool (eg a 2-into-1, filament-swapping hot end), it will display more tools than heaters. Tools may not line up with their respective heaters.

The PanelDue also iterates the heaters from the first defined heater to the last, including all heaters in between, whether defined or not. This means if you have a heater defined on H0 (bed) and one on H5 (Duex output), it will show all the ones in between, eg H0, H1, H2, H3, H4 and H5. For an example, see |https://forum.duet3d.com/post/136207|this forum post|. Ideally, configure heaters on consecutive heater connections.

Due to constraints on display resolution, PanelDue can only display 7 heaters in total on 5" and 7" panels, and 5 on 4.3" panels. If there are more heaters and/or tools than this, some columns will overlap.

These restrictions are largely removed in later versions of the PanelDue firmware. However, they will require you to update RepRapFirmware on your Duet mainboard.

You can use the external SD card socket on the LCD panel if you have used a ribbon cable as described above. Please note, the SPI interface provided by this SD card socket is much slower than the on-board SD card socket built into the Duet. Therefore we recommend that you do not upload files to this card over the network. Use the external SD card socket only if you want to write files to the SD card on a PC and then move the SD card to your printer.

Caution! Do not use an SD extender cable from the SD socket on the Panel Due. Some types of SD card extender cable have been found to damage the SD card socket. Damage to the SD card socket from using an extender cable is not covered by the warranty.

You will need to make a custom 5-way cable using this table of connections. For the PanelDue 1.1, the X5 connector pins are numbered from the bottom end of the connector (the end close to the X5 legend). On the Duet 0.6 and 0.8.5 you need RepRapFirmware 1.17d or later to get support for the second SD card.

There are two types of controller chip commonly used in these controllers: ST7920 and ST7567. Some Duets support one or both of these types - see below for details. Both types use a menu system stored on the SD card, see 12864 display menu system.

An example of this is the Fysetc Mini 12864 Panel. The controller chip is run from 3.3V, so these displays normally include level shifters which tolerate a wide range of input voltages.

Duet 3 Mini provides two 2x5 ribbon cable headers for connecting a Fysetc 12864 Mini Panel version 1.2 or 2.1 (not 2.0) or compatible ST7567-based controller. When using a version 2.1 controller, the colours of the three Neopixel LEDs built into the display can be set using the M150 command with LED type parameter X2.

We do not recommend connecting a 12864 display with ST7920 controller to the Duet 3 Mini because the 3.3V signals provided by the Duet 3 Mini do not meet the specifications of the ST7920 controller chip when it is powered from 5V. If you do wish to try it, you will most likely have to reduce the clock frequency (M918 F parameter) to get it working at all, and it may not work reliably. Also, note that when configured for 12864 display with ST7920 controller, RRF provides the CS signal on the pin normally uses for A0 because that more closely matched the pinout of typical 12864/ST7920 displays.

The Duet 2 Maestro provides two 2x5 ribbon cable headers for a 12864 display using ST7920 controller. The connector pinout is compatible with the original RepRapDiscount design. There is also more information in this thread: https://forum.duet3d.com/topic/7609/conf....

RepRapFirmware 3.2 and later support a 12864 display using ST7567 controller. RepRapFirmware 3.3 added support for a short string of Neopixels on Duet WiFi and Ethernet, so boards that use a Neopixel for the backlight should be able to be controlled. See this thread on the forum for more details.

We do not recommend connecting a 12864 display with ST7920 controller because the 3.3V signals provided by the Duet 2 WiFi/Ethernet do not meet the specifications of the ST7920 controller chip when it is powered from 5V. If you do wish to try it, you will most likely have to reduce the clock frequency (M918 F parameter) to get it working at all, and it may not work reliably.

Use the pins +5V, GND, IO_0_OUT and IO_0_IN on the IO_0 header (Duet 3), or +5V, GND, TX and RX on the PanelDue header (Duet 2). These should be connected to +5V, GND, TX and RX on the TFT, making sure that TX and RX are swapped.

The PanelDue is a color touch screen controller for the Duet and other 3D-printing electronics that support it. This integrated version is a custom-made high-quality 5 inch or 7 inch TFT LCD panel from a leading manufacturer, with the PanelDue controller by David Crocker integrated on the LCD"s PCB.

Connections to the onboard micro SD card socket as well as the PanelDue serial and power connections are all available via a 10-way ribbon cable.  A 300mm long ribbon cable (maximum recommended length) is supplied.

Installing any Duet3D controller board in a 3D printer is a fantastic upgrade that every hacker and tinkerer should experience at some point. Duet mainboards are powerful and feature-rich, but controlling the machine still requires a network-connected computer or directly connected device via USB. Adding a PanelDue touchscreen makes the power of a Duet board available at the machine, regardless of network connectivity or computer availability. Never be disconnected from your 3D printer again with an integrated PanelDue touchscreen.

Every maker is a unique individual with specific needs, and therefore not every 3D printer is exactly the same. For those who choose to upgrade their hardware with high-performance components, the Duet3D platform of mainboards and accessories is a great choice. The Duet controller boards all have direct connectivity to any of their PanelDue touchscreens, which are available in both 5 and 7-inch variants to suit any maker"s needs. Both are 800x480 resolution, the 7 inch simply offers a larger display. Each PanelDue connects to the mainboard via a 4-pin cable that is provided and has a dedicated connection point on the Duet board.

Aurarum produced printers are mostly based on the Duet3d controller boards. We use and sell genuine boards with high success and our customers like it.

The boards can bet either used with common LCD12864 screens or could be used with 5" and 7" touch screen panels of your choice. The touchscreen panels can be either sourced from elsewhere or you could use nicely Duet3D designed integrated panels that a compact, look nice and work out of the box.

The PanelDue is a full-colour touch-sensitive graphical control panel for 3D printers. Although primarily intended for use with Duet electronics, it also works with other 3D printer electronics that supports a true serial port and includes the required support in the firmware, for example RADDS. Support for PanelDue is present in RepRapFirmware and is in the process of being added to Repetier and Smoothieware.

You can buy small quantities of just the the controller board from duet3d.com and from some Duet3d genuine resellers such as Filastruder. Some of these can supply cables and displays too.

2-wire async serial interface with 3.3V signal level (5V tolerant input). An external pullup resistor can be added to improve noise margin when driving 5V printer electronics. Connections to the SD card socket that is included on most compatible displays is available via a 10-way ribbon cable connector on version 2.0 PanelDue boards, and via 5 PCB pads on version 1.1 boards.

The PanelDue controller board. This sits on the back of the display. Its main components are a 32-bit ARM-core processor, a 40-pin connector for the display, a piezo sounder, a voltage regulator, a micro USB socket for programming it, and a 4-pin connector for power and communication with your 3D printer controller board.

An enclosure. You will typically print this yourself on your 3D printer. You can find some printable designs here. Some PanelDue users have done their own designs, such as this one and this one and this one. Before printing an enclosure, check that the design is for the version of the PanelDue controller that you have (1.0, 1.1 or 2.0/3.0) and for the correct display size.

You may need a separate power supply for the PanelDue, depending on whether your printer electronics can supply enough current on the +5V supply line for the TFT screen without overheating. If you will be connecting the PanelDue to a Duet 0.6, Duet 0.8.5, Duet WiFi or Duet Ethernet electronics board with the on-board switching regulator enabled (as in the Ormerod 1 and Fisher kits from RepRapPro and the Mini Kossel R3 kit from Think3DPrint3D), then you do not need a separate power supply. Ormerod 2, Huxley Duo and Mendel 3 owners should read the important note later in these instructions.

To update the firmware on the PanelDue, you will need a USB cable with a micro USB-B plug at the device end and a standard USB-A plug for your PC at the other. If your 3D printer uses Duet electronics, you can use the same cable that you use for connecting the Duet to your PC.

1. If you will be using the 7 inch display with a PanelDue version 1.0 controller board then you need to add a wire to the back of the PanelDue board in order to supply power to the separate backlight power pin. See the image on the right for where to connect it (click on it to enlarge). The version 1.1, 2.0 and 3.0 controllers include this connection already.

3. Connect the 4-wire cable to the PanelDue controller board (you may not be able to get at it after you have secured the controller to the enclosure) – see photo above. If you bought a complete kit from Think3DPrint3D, the cable supplied may have a blue wire in place of the white one shown here.

4. Very important! If you have a version 1.0, 1.1 or 2.0 PanelDue controller, set the 3.3V/5V jumper to 3.3V (this is the voltage supplied to pin 2 of the 40-way connector). The 5V setting is only used with 4.3″ and 5″ displays from Itead. All other displays expect 3.3V and you are likely to damage them if you supply them with 5V. The version 3.0 board does not have a jumper, it is set to 3.3V and can only be changed to 5V by cutting a trace and adding a wire.

5. Fit the display to the enclosure using four of the 2.9mm x 6.5mm self-tapping screws supplied with the PanelDue controller board. Make sure you fit it the right way round, so that there is room in the enclosure for the PanelDue too (next to the display or below it, depending on the model of display). Hint: while doing up the screws, press the screw in firmly with the screwdriver – this will reduce the risk of the mounting pillar delaminating.

7. If you have a version 1.0 or 1.1 board, use the remaining two 2.9mm x 6.5mm self-tapping screws to secure the PanelDue to the enclosure. The version 2.0 and 3.0 boards use a single mounting hole and self tapping screw.

The PanelDue controller is supplied as standard with firmware for driving a 4.3 inch 480 x 272 pixel display. If you use a different display, then you will need to re-program the board with firmware for that display. There may be more recent firmware available even if you are using the recommended display.

Locate and download PanelDue firmware for your display from https://github.com/dc42/PanelDueFirmware/releases. Choose firmware with 4.3 in the file name if using a 4.3 inch display, or 5.0 if using a 5 inch display, or 7.0 if using the 7 inch display (do not use the 7.0E version) Choose firmware with -v3- in the name if you have a version 3.0 PanelDue controller board, or with -v2- in the name if you have an earlier version. File PanelDue-5.0i-7.0i.bin is for versions of PanelDue electronics integrated with a 5 inch or 7 inch display.

Use a suitable cable to connect the micro USB connector on the PanelDue controller to a USB port on your PC. Caution! With version 1.0 and 1.1 PanelDue boards, take care not to exert too much sideways or up/down force on the USB connector, or you may pull the USB connector off the board.If the board has already been programmed then the backlight should illuminate.

Press and hold the Erase button of the PanelDue for at least one second. You can access this button by pressing the end of a straightened-out paper clip through the hole in the enclosure.

Identify the COM port number or port name of the PanelDue board on your PC. If you use Windows, you can do this via Start->Control Panel->System->Device Manager. Expand Ports (COM and LPT), and look for Bossa port. Make a note of the port number. If you can’t find the port, try repeating the Erase and Reset sequence, or disconnecting and reconnecting the USB cable, or try a different USB port on your computer. Note: the port number of the Bossa port for PanelDue will not be the same as the one you use when uploading firmware to Duet electronics.

Replace COM9 in this command by the COM port number you found, and PanelDueFirmware.bin by the path to your downloaded firmware file. It is possible to use the interactive version (Bossa) instead of bossac, but if you do then you must check the Erase all, Lock, and Boot from flash boxes.

On version 2.0 and earlier boards, whenever new firmware is uploaded, the touch panel calibration and touch pad orientation is lost. Therefore, on starting up the software enters the touch panel calibration phase. Touch the spots as instructed on the screen as accurately as possible. It is more accurate to use the tip of your fingernail or a stylus (print one!) rather than the pad of your finger. If the display is upside down or inverted left-right, you can correct it after touch calibration using the options provided on the Setup page.

If you have a PanelDue with a 7 inch TFT panel, then some PC USB ports and especially laptop USB ports may not be able to supply enough power to the PanelDue when the backlight is on. If you press Erase and Reset while the PanelDue it powered from your controller electronics, then the backlight should turn off, which should resolve the problem. Or you can disconnect the PanelDue control board from the TFT panel (unless you are using the integrated version), then upgrade the firmware, then reconnect it.

After you have connected the PanelDue to your 3D printer, you can still update the firmware using the same procedure. If you have a version 3.0 PanelDue then you must either disconnect it from your 3D printer first or power up your 3D printer. Version 2.0 and earlier can be updated without disconnecting them from your printer electronics even if the printer is not powered.

If you have a PanelDue 2.0 board and a Duet WiFi or Duet Ethernet and you want to use the SD card socket attached to the display, connect a 10 way straight-through ribbon cable between the box headers on PanelDue and on the CONN_SD socket on the Duet WiFi.

If you have a version 3.0 PanelDue controller and a Duet Ethernet or Duet WiFi with PCB revision 1.01 or later, then it is possible to connect the PanelDue to the Duet using just the 10-way ribbon cable if the two are close together, and you can leave out the 4-core cable.

The ribbon cable must be kept short, preferably no more than 200m long and certainly no more than 400mm. Using a long ribbon cable may give rise to unreliable operation of the SD card and also any PT100 or thermocouple daughter boards attached to the Duet.

If you have a Duet 0.6 board without the DueX4 expansion board, use the 8-way connector provided to connect the PanelDue to the end of the expansion connector on the Duet as shown here.

If you are using A Duet 0.6 with the DueX4 expansion board, then you need to connect the PanelDue to the 36-way expansion connector on the DueX4. You will can use the 8-way shell to connect pins 1, 4 and 5 and the 4-way header shell to connect pin 21. Here are the pin numbers:

Important! As already mentioned, some printer electronics (e.g. Duet 0.6 if you use an external 5V linear regulator) are unable to provide the current on the 5V rail needed by the touch screen display. In these cases you should do the following:

Ensure that the firmware you are running on the Duet or other printer electronics supports communication with the PanelDue, and update it if necessary. For Duet electronics, I recommend using the 1.19.2 or later series of my fork of RepRapFirmware, available here.

Power up your 3D printer electronics. The display should light up. Initially all numeric fields will be displayed as zero. However, once your printer electronics starts responding to requests from the PanelDue, the fields should show the correct values.

If the PanelDue does not pick up the temperatures, machine name etc. from your printer, it may be that the baud rates do not match. You can adjust the baud rate on the PanelDue via the Setup page. You can adjust the baud rate of the serial port in RepRapFirmware using the M575 command. Both PanelDue and RepRapFirmware default to 57600 baud, so there is normally no need to adjust the baud rate.

The touch panel displays draw significant current from the +5V rail. The on-board switching regulator on the Duet 0.6, Duet 0.8.5 and Duet WiFi boards can easily handle this. However, the linear regulator on the separate 5V linear regulator board used on the Ormerod 2 and Huxley Duo will not handle the load without additional heatsinking. So you will need to add a heatsink to the linear regulator. Make sure that the heatsink and fitting screw cannot short against the enclosure, or anything else! Monitor the temperature of the 5V linear regulator for a few hours to check that the heatsink is effective enough. Alternatively, either power the PanelDue through from a 5V USB power supply as already described, or enable the internal 5V switching regulator on the Duet electronics board.

If you are using Arduino-based electronics instead of the Duet, then you will need to identify a serial port on the board with available TxD and RxD pins, and the firmware on that board must be capable of receiving gcode commands and sending replies in the required format through that port. Connect the TxD pin of that serial port to Din on the PanelDue, and the RxD pin to Dout. If your electronics uses 5V signal levels instead of 3.3V, then I recommend that you also connect a 10K pullup resistor between the Dout pin and +5V. The PanelDue will tolerate a 5V signal on its Din pin.

If your printer electronics does not already have an SD card socket, but has provision for connecting one, then you may be able to use the socket on the back of the display panel. The version 1.1 PanelDue controller boards has pads for adding a 5-way right-angle Molex connector for this purpose (labelled X5 on the printed circuit board). The version 2.0 and 3.0 boards have a 10-way ribbon cable connector. Note that SD cards use 3.3V signal signals, therefore if your electronics uses a 5V signal levels then you will need to use level shifters.

If you can write C++ and wish to make your own modifications to the firmware, then you can find the firmware source and build instructions at https://github.com/dc42/PanelDueFirmware.
