BLtouch error
BLtouch error
Hello, I recently bought A20M geeetech. I did everything the manuals says. I upgraded the firmware because the port cannot be read. After upgrading my LCD went blank. I tried to upgrade using Arduino and now the configurations are all messed up xyz axis, height and levelling are not in proper places. And when I try to connect to computer software, it says BLtouch error. Can you please help me.
