Broken Print Core?

Recommended Posts

Posted · Broken Print Core?



I have recently begun printing face shields to give to our local hospitals, running the S5 for nearly the past 24 hours . When starting the next batch this morning I got this error message. "Nozzle offset probe failed..."


I noticed that core 2 was much lower than core 1. In an attempt to troubleshoot, I switched core 1 to position 2 and vice versa - core 2 is still lower than 1. I guess the problem is how the core is sitting in the machine? Has anyone experienced this issue before? Any help would be greatly appreciated!

    When inserting and removing right core it is supposed to be lower.  But if you then slide the switch on the right side it should go up above the left core.


    Some things to try - clean the nozzles while hot.  Loosen the 3 leveling screws so the gap is around 13mm (you want the springs of the bed to be weaker than the springs in the cores if possible).  Check for loose wires inside the print head (open the door and in the bottom there are 2 wires - make sure they aren't loose).  Check for loose wires inside the top of the print head (remove rear two long screwd, remove cover, make sure connector is seated, reassemble).  Don't touch the printer when it is auto leveling.  Keep strong electromagnetic emitters (like a phone or laptop) a meter or more away from the printer during auto leveling.
