Re: New TFT control panel for 3D printers

I now have prototype PCBs for the TFT 3D printer control panel. I have them working with the 3.2" widescreen and also with the 4.3" display shown in these pictures:



Unlike most other LCD control panels for 3D printers, this one does not require the main processor of the 3D printer to drive the display. Instead, it has an on-board 32-bit processor, which talks to the main 3D printer control board via a serial link. Currently, it is supported by my fork of RepRapFirmware, which will also support Delta printers in January. Other firmware would need a little extra gcode support added to be compatible with it. It uses 3.3V signal levels on the serial link, however it is 5V tolerant and should be able to drive a 5V Arduino serial input with the addition of no more than a pullup resistor.

Drop me a PM if you are interested in ordering a board, or follow this thread [forums.reprap.org] for updates. The draft fitting instructions are at [miscsolutions.wordpress.com] (photos to be added soon), and the on-board firmware source code is at [github.com].
