UM3: Can't seem to level 2nd head


Recommended Posts

Posted (edited) · UM3: Can't seem to level 2nd head

At some point the 2nd print head got out of level, so low that even by the 3rd-4th layer the right core can't extrude anything. I've tried removing it and reseating it, no help. Tried reseating the other core. So I started running manual and automatic levels. 2nd head is still too low. I have the 1st (left) print core levelled beautifully, giving me the best first layers since I got the machine.

Am I missing something obvious?


-- Addendum

Today it keeps trying to autolevel with the 2nd/right print core lowered, causing it to fail. I remounted both cores, manually levelled fine, and now it's doing this:

    Think checking if the sensor is ok could be a fist step.


    In my S5 it's under Maintenance / Diagnostics / Leveling sensor test

    correction; I see you have an ultimaker3 (not S3), so it's under Maintenance / Diagnostics / Bed Level Sensor.


    Another common issue is a not proper;ly seated cable connector in the printhead. Unscrew the back to screws of the printhead, open the cover, push the connector to make sure its seated well.
