Printer Shifting Models

[scubaru]

Typical issue when nozzle/hotend/fan is slamming into the plastic, which result as a brief moment of being stucked. This will cause everything to shift. I've done that several times on my ultimaker. Stupid stock fan had to touch the print!

That carbonized PLA! I've never managed to carbonized any PLA filaments so far! Temperature control must have gone mad!!!

Just make sure nothing might interfere with the printing.

If the slicer is really the cause, I suggest you to use CURA.

I thought about it being the code the slice program generates so I changed the orientation of the part in the printer and thats when the last issue came up. Could there be a corruption in the file? I printed two more parts (smaller parts I know printed in the past) and they printed just fine. They were a lot smaller so either its just luck or there is an issue with that particular file.

Overheating stepper drivers can shut themselves down, causing missed steps. It looks like your Y stepper overheated and shut down until it cooled sufficiently to start up again, resulting in a shift. Is your electronics board getting hot in the middle of the print? Pointing a fan at it can help.

I never even considered this. I can't say how the electronics board feels as its underneath the printer. The stepper on the other hand is easily visible, maybe I'll have to run another big print and look for abnormal heating of that stepper.
