Unable to read tmc uart 'stepper_Z1' register IFCNT
Hi everybody. I tried to hook up a EBB42 and connected the endstop wrong. The EBB-board got fried and I got "unable to read tcm uart" messages and nothing on the printer works. After some trial and errors i thought that my MCU (Octopus v1.1) was toasted. I ordered a new one and hooked it up today with a flashing of the board and a bran new printer_cfg. Same errors. I tried to change the stepper drivers for new ones for all motors. Same errors. I have tried to disconnect endstops, thermistors, heaters, motors, fans from the main board at one at the time but same errors. I am running out of options here I think.
Depending of what I disconnect I get the error on Z2, Z3, X and Y as well.
If I visually inspect my old MCU I cannot see any damages on it. Likewise on the old stepper drivers. Does anybody have any suggestions of what can be wrong and what to check? I am really unsure to proceed.
