duet lcd panel made in china

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.

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.

Sigh !! My SB3 can display Chinese perfectly but on the new Duet controller all my chinese songs" characters displayed like garbage. It"s so pity that the new Duet can"t support Chinese. Is there anyone know why Duet did not follow SB3 ? when will the controller support Chinese ?

SB3 can support Chinese perfectly. That"s why I pre-order SB Duet. Most of the new products can support old version"s features. Is it difficult to include the CJK fonts in the SBC software ? There are a lot of SB fans in Taiwan. Hope you can solve the problem shortly.

1. enable remote access on the Duet remote (Settings->Advanced->Remote Login->Enable SSH) - it will tell you the remote"s IP, I assume 192.168.1.3 for the example

I try to press the LED button until the red light is flashing, and controller let me choose the player "Squeezebox xxxx". Then , I select to connect to ethernet for the player , and nothing happened to the duet box but keeping flashing the red light. And the controller just tell me something like "fail to connect , try again ?" over and over again.

Thanks to all for the tips. I didn"t realize one could replace the fonts in the Duet controller and was despairing of getting CJK characters rendered correctly.

I"m just popping this thread, because I too find it quite disappointing that the Duet currently doesnot have an asian character set included, or at least a very easy way to deploy specific character sets to the duet so that I can select what I want within the storage limits.

If there isn"t an opensource font available, surely Logitech have rights to a commercial one hanging around, or worst case Slim could get one made. I regard it as pretty important - as with other users, my previous experience with Slim products, it never crossed my mind that the Duet wouldn"t support this. Very un-Slim.

Duet Display is an app that lets you turn your iPad into a second Mac monitor. And the team behind it just released a major update that makes it much more efficient — it consumes less CPU resources and is now recognized as a true external display.

If you’ve used Duet Display over the past few years, you may have seen a change that made it worse, not better. At some point, Apple updated macOS and broke Duet Display’s method.

Duet Display had to use AirPlay as a fallback method. It made the app much less versatile as you were restricted to a handful of 16:9 resolutions with black bars.

But this is a thing of the past as Duet Display found a way to leverage GPU acceleration. It means that your iPad now appears as a display in macOS settings. It also should be more energy-efficient. In my experience, it’s now much closer to a normal external display. If you’re traveling and need a lot of screen real estate, it’s a good solution.

Luna Display has been able to do the same thing using a hardware dongle. Duet Display is now catching up with its competitor by releasing this update.

Version 2.0 is a free update. Make sure to download the latest version on your iPad and your Mac. For new users, Duet Display costs $10. You can optionally pay $20 or $25 per year for additional features, such as wireless connectivity and Apple Pencil support.

Duet Display is a clever software app, which has been available for years, that allows users to convert an iPad into a second display for their Mac just by plugging it in. But it was never the same seamless experience that a “real” external monitor offered.

That’s changing with the latest macOS 10.14.2 update, which allows Duet to finally enable full hardware acceleration. The company claims that it allows the app to take advantage of the GPU to work even faster and with greater energy efficiency, especially for things like watching video or working at higher resolutions, via 9to5Mac.

To take advantage of the new functionality, just make sure that you’ve updated both your Mac and the Duet Display iPad app to the latest versions. For users who want to give Duet a try, the app is also on sale for $9.99, down from the usual $24.99 price tag.
