¶ Phenomenon description 1
After clicking "Home", the X or Y axis hits the limit switch.
¶ Cause analysis
Endstop switch error, unable to trigger.
¶ Troubleshooting and solution
- Measure the continuity of the X and Y-axis limit switches.
The Y-axis limit switch continuity is consistent with the X-axis, measuring continuity between 1, 3 and 2, 3 (when the contact blade is pressed down
Measuring continuity between points 1 and 3, and points 2 and 3 (when the contact is engaged/actuated
- Measure the resistance to ground of the X and Y axis limit switches.
X-axis limit switch
Y-axis Limit Switch
¶ Phenomenon description 2
After initiating the homing process, the X-axis does not engage the endstop; subsequently, the Y-axis executes the homing sequence triggering the endstop, followed by the X-axis reversing and making an impact.
¶ Cause analysis
Endstop Exception Triggered, Limit Switch Damaged or Main Control Chip Faulty.
¶ Troubleshooting and solution
Check the continuity of the X and Y-axis limit switches.
The Y-axis limit switch should have the same readings as the X-axis, which involves checking the continuity between terminals 1 and 3, as well as 2 and 3 when the actuator is depressed.
Measuring the electrical continuity between points 1 and 3, and 2 and 3 (when the contact leaf is pressed down).
