Hello,
I just installed a new board and TFT display on my Ender3 but I'm getting a message "No printer attached".
I troubleshooted the wire connection from the TFT to the board.
On the TFT side the 10pin ribbon cable is connected to the EXP3 slot.
The RS232 cable (4+1) is connected to the RS232 connector on the board. I tried the connector both way (reverse and back) with no success.
I'm still getting the error message on the screen.
Are there any other connections between board and TFT that could cause the TFT not to detect the attached printer?
I reviewed several vid's on YouTube but here were of no help for my problem.
And btw. I'm using the stock BTT firmware for the board from GitHub (with BLTouch).
I'm at the end of my wisdom and don't know how to get it going.
Any help is much appreciated.
Part-2:
After some further testing, I found out that the Marlin mode works fine. I seems that the problem appears only in the touch-screen mode. Will continue some testing incl. settings for BL-Touch and some test prints.
Firmware: BTT Stockfirmware for BLTouch with z-homing.
