4 years ago Sounds great. I love it to play with the features in Marlin.
Happy printing

SKR Mini E3 V2.0 was in stock in town so I upgraded and stayed with a more plug and play solution for now.
The upgrade to V2.0 went well and everything works as it should. I finally compiled with VSCode so I'm on my way to more dangerous heights.
Thanks again for helping me troubleshoot and learn more about 3D printing. I'll close this issue in a couple days.
Drew.

I upgraded the SKR Mini E3 V1.2 board and TFT35E3 V3.0 display at the same time and everything worked perfectly for a week then the touch screen went black. I checked the connections on the board and display and everything seemed okay but the screen remained black.
After much testing I discovered both the Marlin and touch screen modes light up if I leave the ribbon cable on EXT3 and connected the serial cable to the SWD port on the TFT35. I can print and everything works fine on the Marlin screen but I can’t clear the No Printer Attached message on the touch screen by toggling the UART settings to 115200. Therefore I can’t print or send gcodes from the touch screen.
With the proper configuration of the ribbon cable attached to EXP3 and the serial cable attached to RS232 the TFT35 is black. If I then remove the serial cable from RS232 the TFT35 remains black. If I then connect the serial cable to the TFT35’s SWD port I have access to both screen modes and I can print from the Marlin screen but I can’t clear the No Printer Attached on the touch screen. I always power off before changing any connections and I haven’t changed any of the connections on the motherboard since the original working upgrade. I haven’t made any firmware changes or printer mods other than install a plug and play filament runout sensor to the TFT35 that worked perfectly.
Back to the ribbon cable on EXT 3 and the serial cable connected to the TFT35 SWD port with Marlin mode working okay and No Printer Attached on the touch screen mode, here’s what I’ve tried from the Marlin screen: Flashed the original firmware TFT35 E3 V3.0.26.x to the TFT , flashed Bugfix 2.0.x to the motherboard from its original microSD card. Both BIN files changed okay to CUR. Flashed rhe latest Bugfix 2.0.x from Github, Initialized EEPROM, restore failsafe and saved EEPROM. I also replaced the ribbon and serial cables and tried V3.0.25.x on the TFT35 but no change. If I remove the serial cable and attach the ribbon cable to EXT1 I have the touch screen with No Printer Attached but no access to the Marlin screen. Strange. I haven’t done any compiling yet therefore I haven’t been able to check the firmware’s port or baud rate settings on the SKR Mini E3.
This upgrade is awesome and I miss the touch screen’s additional functionality. Is this a firmware issue or hardware issue? What do I need to do to get my SKR Mini E3 and TFT35 E3 working properly again? Thanks, Drew.
