Ovalisation Z Axis
Hi,
My printer has been fine for months, but of late the holes are getting more ovalised and reaching a point where I'm having to ream them for use. The z height hasn't been changed and was right. I get a sexy first layer. I haven't changed filament manufacturer which I test print every new reel and most annoyingly the prints come out at the right dimensions. The one shown should be 32mm and comes out at 32.18 which is good enough. What else should I look at? I'm wondering if something is binding but it is running on misumi bearings which seem fine.
Any thoughts?
RE: Ovalisation Z Axis Update
It seems it's not only holes that are affected, this has printed with the hexagonals squashed too. I'm wondering if this is slicer based? I'll try a different slicer and see how that goes
