I have built my Mellow Vzbot 330 printer following the manual given on the website, now I reached the point to turn it on for the first time, when I try to click home, the klipper shuts down giving the error “Unable to write tmc spi ‘stepper_x’ register GLOBALSCALER”. Solution that I have tried is to maybe find the faulty driver, but I don’t know exactly how to do it, what I basically did was disconnect are the drivers and connect them one by one to see which one is faulty but it still gives me same error in every case even when there are no drivers connected to the main board.

Note that in the first one I did not update the pitb, but in the second one everything is updated. It is under test, so there is no power to the motors, I think it is broken, there is no fan on the two pins gpio0 and gpio18, and the motors ffffff*f, only temperatures, other connections not tested, I have already tested on USB, USB CAN, on CAN with 3 different CAN boar…

Unable to write tmc spi 'stepper_y1' register GLOBALSCALER

Did anyone manage to solve this issue for tmc 5160s. I was experimenting with different spi buses I used the Pe15 Pe14 Pe13 at first and got the same message. Also changed run_current, spi speed, went from 48 volts to 24 volts, plugged the diagonal jumper in, and tested the drivers on a different board (still work). Any su…
