"Unable to read tmc uart 'stepper_y' register IFCNT"

[civic quiver]

Everything is in the title...

Someone have a solution about ?

IFCNT I believe is an internal error to the driver. Make sure the driver is properly seated, but if that doesn't help I would try replacing the driver

[civic quiver]

i've tryed to switch drivers from positions but nothing happen. X and Z stepper are OK

if i change connection between X and Y, X doesn't work and y work

i've no idea

[next creek]

have you replaced the Y stepper driver with a new stepper driver?

[civic quiver]

doesn't work

[next creek]

can you elaborate? Doesn't work how?

[civic quiver]

i've switch X driver (working) with Y driver

Same issue.
After that i've tryed to switch with Z driver, same result

I've changed position of stepper to tchek if it's not down but Y stepper work when i connect it on X position

i think i've big problem with SKRat v1.0.
Nothing work on it.

Absolute positions of my axes are wrong, endstopper doesn't work.

I've probably a problem with the board

Issue fixed
