I am finding some jobs are losing the place somewhere during the print itself.
You can see in the photo, the rectangle has closed off about 1mm out.
The difference is always about 1mm. It is always front to back, never side to side.
It doesn’t happen every time, just frequently enough to be annoying.
It’s not the material moving, this still happens when it is fully pinned and taped down.
Running the same job again will work fine - which makes thing I’ve got a bit of muck, or a stripped gear or something somewhere.
I’ve cleaned the belts and the runners on the sides.
Before I get into a serious take apart to clean everything does anybody have any suggestions?
