UM3+ just stops in middle of print

Recommended Posts

Posted · UM3+ just stops in middle of print

@kmanstudios the printer in our office seems to stop printing due to communication problems with the print head, but not catching that error correctly. We have replaced the cable to the print head and haven't had an error yet. But our testing time so far with the new cable does not guarantee that this is the true cause.

But you can see if you can contact your local sales contact to see if you can get a replacement print head cable. You could have a slightly bad wire in your current one.


I will definitely look into that as I do get occasional printhead communication errors.


(But nothing messes up your printer as well as a tesla coil...)

LOL :p

    I have the exact same issue with my UM3 since 2 days : it stops after a few hours of printing displaying ER18.

    Reading your posts I guess that it may comes from the fact that I just moved my UM3 to the basement( with a washing machine next to it). It may afect the printer power management system (espacially if the UM engineers didn't separate the power circuit from the command circuit in the printer design...).

    Do you think that using a UPS could ease the pain ?

    You could check to see if the printhead cable came a bit loose during the move. What you report is part of the communications error messages.


    This also is something to check with this:


    Those two errors are connected.

    Unscrew those two screws in the top, back of the printhead out, slide a small screwdriver in those little slots and it will slide right off. With a small instrument, push down on the plastic sides of the cable connector. Mine has come loose when using a lot of heat over time. I am guessing that the heat makes the plastic soft and loosen.

    Also, next to a washing machine? Doesn't that throw your humidity levels way up?
