Hello, I fresh installed ros and I get this error. Any idea what it could be? Broken stepper cable maybe? Thank you

You get that message immediately on restart?

#

No. I set the kinematic center and I am able to move all axis few times and then I get it

Sounds like one of your TMCs isn't getting voltage. Try swapping them and see if the issue follows the driver

Swapped the first 2 and now I get this: Unable to read tmc uart 'stepper_x' register IFCNT

#

So the driver that moved, take it back out and look at it closely to see if you can find anything visibly wrong, or just replace it

#

I did replace it with one from my V3 and it works now

#

guess bad driver on arrival

#

thank you for your suggestions
