Hello, sorry about the delay in response.
I have watched exactly what happens when the error occurs. During printing, maybe on the 4th or 5th layer, the extruder will stop moving, feeder motor will stop (I think, didn't hear grinding noises), both print core lights will turn off, but the printer will think that it is still printing. If I select abort print, it will sit there motionless and then display the Z or X/Y limit switch error, presumable because it thinks the extruder/bed is moving and never detects the limit.
I checked the cables underneath the printer and everything seemed fully seated. I will check the print head cable tomorrow, haven't done that yet. It's possible that this is loose since I have had to open the head before to clean out a clog.
Thank you!
