Hi, I’ve completed my 4.1 build and calibrated it … all fine, until i tried to raise the Z axis to put bit in … the top stepper motor (vertically mounted) is not moving. I swapped the two motor leads round and the bottom z axis stepper motor is not working. Have the latest firmware, so i guess the board is to blame? … can you help, please?

I will DM you a code for a replacement controller board right away. I’m sorry for the trouble!
