Dual extruder resetting mid-print when using CURA

Post by 3dztech » Thu Apr 19, 2018 7:02 pm

Just upgraded my M2E to dual last night, not too difficult but some minor issues have come up...

Currently, when a print is about 50% complete the extruder apparently decides to go ahead and shift off the print to right (waaaay off, well over 100% off) and continues printing in the new spot (which obviously fails the print).

I'm using CURA 3.2.
I don't notice any strange mechanical movements/sounds when this occurs.

I find this issue very perplexing, almost as the most extreme example of layer shifting but the printer doesn't return to it's original position... Has anyone ever seen or heard of an issue like this?

Re: Extruders move off print and continue

It looks like at some point mid-way my X and Y (extruder and bed) parts appear to just randomly reset to home position and then attempts to start the print back up but fails to find the original origin....

UPDATE:
I can't get the issue to replicate using Simplify3D... What could CURA be doing that would cause the X/Y axis to reset mid print?
