L-Extruder limit sensor is abnormal
a. Switch nozzle to left. Then use order “M119” to check the status of sensor. The value of it should be “1”, means left sensor activated. Figure 22-1. (Get approach to INTAMSYS service team on how to use this order)
b. Take extruder assembly off. Manually switch the nozzle and check if the flag is fine
to activate the sensor.
c. Replace the sensor. (L and R sensor cannot be swapped with each other)
d. Replace L interconnection board.
