Hi there,
Got my 350 today and after the first power on , setting up wifi, it led me to the printbed calibration. The x-axis went an seemingly random way to the left, touching the end with a harsh mechanical sound. Then the process stopped, waiting for minutes didnt help. Y- and Z- axis didn’t move at all. Cycled the power for a new try, the same procedure. No chance to swipe left to get into another part of the menu. After power up it returned direct to the calibration.
Solution: Connecting the CNC-head instead of the printer module allowed me to enter the normal menu as the CNC doesn’t need to be calibrated. Tried direct controlling of the movements but there was no response from the drives. Firmware updates were offered and i installed all of them. After restart i was able to move the drives as intended. Switched to the printer head again and the bed calibrating worked as supposed.
