VC4 400mm IDEX

ERROR:
Unable to read tmc uart 'stepper_y' register IFCNT

Running through commisioning guide and getting an error with stepper_y.

I replaced the stepper with a new spare, same behavior

Then I swapped the positioning of all steppers, same behavior

I Jiggled and inspected the wire, same behavior

What is my next path for debuggin this?

I swapped wires for Y and Y1, error remains the same

undone python
#

so the error stays on the same board socket, doesn't follow the stepper driver?

#

Triple check the jumpers on that port

topaz sky
#

correct, juimpers as in under the stepper?

#

FWIW MCU is octopus pro H723 1.1, not the one that ocmes iwth thge kit

undone python
#

yes, the ones under the stepper
