We discussed an “All low” error here. That was related to insufficient powering of the SKR Pro. Can you please check whether you powered it correctly, i.e. it is important to supply 12V power to both, the ‘MOTOR POWER’ and ‘POWER 12V/24V’ connectors.
The baud rate looks fine but still says no printer found
It is normal that when starting up the TFT for a couple of seconds shows ‘no printer found’. But this message should disappear after a couple of seconds. Can you please confirm that this is the case for you as well.
The screen is a TFT35-E3 V3.0.1
For this screen, the correct firmware file is BIGTREE_GD_TFT35_V3.0_E3.27.x.bin. But if you copied all *.bin files into the SD card’s root folder, the TFT would have picked the relevant automatically.
Additionally my endstop switches aren’t telling the motors to stop when they get hit.
Does that mean you can successfully operate your machine via the TFT? Or how did you test the endstops?
There’s a couple of more things to check, but I’d need the information above to advise. Could you please also provide some pictures of the messages you described here.
