Hello, I have a LR3 with a MKS GEN L 2.1 board and TMC2209 drivers that was working fine. The PSU is 24v and it is powered on. However, now, one of them is outputing an error: All LOW TMC CONNECTION ERROR. This issue is on the Z axis and only Z2 displays this error. The strange thing is that the motor is working, but is really out of sync with the Z1.
I already have swapped the motors and drivers and the problem still persists in the Z2. The output for the M122 command was:
Testing X connection... OK
Testing Y connection... OK
Testing Y2 connection... OK
Testing Z connection... OK
Testing Z2 connection... Error: All LOW

Does anyone has any ideas about what might be causing this? Thank you in advance.
