Need help please, new to 3d printing，I have had an Ender 3 pro for a couple weeks now, everything has been going great for the most part. ive just noticed one issue ive had on at least the last 3 prints for sure. As it is printing when it gets to 1.63mm in the Z axis, it prints that layer and then always drops down to 1.57mm and prints another layer. Seems to print fine after that, i havnt noticed it drop down again any other time while its running. I can hear it even just barely scraping the plastic as it goes back and forth. Been running 60mm for speed, .15mm layer thickness, 200C. Doesn’t seem like a level issue. Im not sure if this is something i accidentally did in cura maybe? Any suggestions would be appreciated!!
Try a different slicer.
Orca Slicer, ideaMaker, Prusa Slicer, Super Slicer…
