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

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

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

I did replace it with one from my V3 and it works now
guess bad driver on arrival
thank you for your suggestions
