Dave, you’re creating new topics when replying to your original topic would be sufficient.
Looks to me like your laser is failing to activate the Y homing switch. Or if it is activating the switch the switch is not functioning as it should.
- Check that if you manually move the laser head back that it can physically activate the Y homing switch. Can you feel and hear it activate? If it’s not activating, identify why it’s not activating and make the necessary adjustment.
- If the switch is activating then you’ll need to test the switch to make sure it’s making proper contact.
