M300 Dual X and Y endstop error message


Firmware update were parallel with our maintenance period (after 300h), so we clean, lubricate, check and run calibration functions. In result we have two problems:

  1. Axes verification test after 4-5 min of movement the extruder stops in corner where both endstop switch (X and Y) are placed then message error apears #5:5.
  2. We run the Hotend switch calibration procedure, in the second step of process where we need to positione the extruder close to the left bumper the extruder does not want tu start, strange nois are became from back of the printer like slipping belt on the teeth wheel. error message apears #6:5
    We did the basic maitenance steps dedicated for every 300h of printing. Currently we have printed 336h
