Hello,
I'm relatively new to the 3D printing scene and have been going through the learning process of setting up my first printer and printing a few of my engineered parts/ etc. I'm very familiar with scripting and have found my issue in the gcode, and is not a firmware or mechanical problem on the printer. I'm using Cura 3.2.1 and been having an odd issue where, on particularly large prints, the absolute extrusion value will be defined to some extremely far off value and then proceed to eject all the filament, just for it to continue that section of code (for example an inner wall) - then finally return back to the extruder value where it should have been working off from. This results in huge retractions (which i had OFF in cura, retractions were disabled) and then also where the filament re-catches...extrudes meters of filament just to "catch up" resulting in a blob of where the event occurred. Sometimes the retractions and "catching up" happens in reverse order. See pictures:
(Find "Z144" and scroll down in Gcode)
Is this a bug? I've tried various settings and this happens on different models as well. I've tried with and without retractions as well as combing On/Off.
Layer view looks normal and also inspected at the affected layer with playback:
