Nozzle 2 not retracting for Nozzle 1 to print


Recommended Posts

Posted · Nozzle 2 not retracting for Nozzle 1 to print


I started to notice that my UM3 will not lift/retract nozzle 2 during auto leveling or when starting a print where nozzle 1 is to be used.

I did a manual leveling and disabled auto but im concerned the quality of the prints will be compromised.

How can I fix this issue?


Thanks in advance

    1) There's a little lever on the print head.  On the right side.  Slide that frontwards and backwards and make sure the right hand core is moving up and down.  If not then there is probably a broken part in there and you can order it but first take the head apart to figure this out.  There is lots of documentation to be found.  google it.


    2) If that works then you need to go into maintenance/calibration and run the "lift switch calibration" procedure.  After you've done it a few times it typically takes about 20 seconds to do.  Super easy.  As easy as say changing a core.
