SKR Mini E3 V3 and TFT35 V3.0.1 - no printer attached #46

Open boudlergit opened 1 year ago

Updated my Ender 5 Plus with the Mini E3 V3 board and TFT 35 V3.0.1 display.

I've updated Marlin to the most recent 2.1.x bugfix version. I have updated the display firmware per the github page.

Config.h has been updated to reflect all of the stuff

define SERIAL_PORT 2

define BAUDRATE 115200

define SERIAL_PORT_2 -1

define BAUDRATE_2 115200

define CR10_STOCKDISPLAY

I've made sure that the baudrate on the display matches the firmware. I've tried 115200 and 250000.

When I switch over to Marlin Mode, the screen says Marlin Mode at the top but I cannot do anything. The touchscreen side works but is giving me the No printer attached error.

Fairly certain I have wired it in correctly. Using the EXP3 slot on the TFT.

Any suggestions are greatly appreciated.

Attention SKR 3 and SKR mini E3 V3 are different hardware.

The EXP3 connector is used to display the marlin screen. The TFT connector is used for communication in touch mode. You must therefore also have a serial cable connected via the TFT connector.
