[ER16 z axis is stuck on UM3-EXT]

Hi everyone,

our 3D printer is recently stopping printing from time to time. It simply freezes during printing. Often, but not always, ist shows the Error16: " The z axis ist stuck or the limit switch is broken." However, the limit switch seems to work fine. The homing of the build plate never fails and the activ leveling also works. No damage or jamming is visible on the z-axis or the swich itself. We have also reset the printer and lubricatet all the axes. We have also cleaned ist, so that no particels can block the axis or the switch. Does anyone have any clue? Thanks in advance!

Thank you all for your tips. They were all useful. The wiggling part gently and the pressure bit helps. Sorry for such a rookie question.

 

@Job_van_gennip as a matter of fact I did

@Smithy thanks!

@Enigma_M4 thanks a lot!

 

 

[Print Core Stuck - Ultimaker 3]

Hello there,

 

I recently removed AA 0.4 core on my Print head slot 2 and put in a BB 0.4 core and now it won't come out.... I noticed another post where the Ultimaker Rep mentioned/showed pictures of how to pull it out correctly (vertically with a specific grip) but that didn't work...

 

Should I take it in to a local shop? Does this mean I will need to get a new print head? I purchased this second hand and its frustrating on what I thought would be pretty darn basic.

 

Also, on a side note... it looks like the print heads are not lining up horizontally. Could this be indicating an issue?

 

Thanks,

Bryan
