Having issues with taller prints in the A350. After about 8 inches the extruder appears to drag on the print which causes the heated bed cover to drag/slide around. This completely messes up the alignment.
I feel like there should be a lip around the edge to prevent this, but it wouldn’t make sense to print it with thermoplastic. Alternately, I was considering drilling the mounting screws for the heated tray straight through the cover to prevent this from happening.
Haven’t heard of that issue being a problem before, usually the magnets are strong enough. Maybe throw some binder clips on the corners?
Edit: oh yea, and also fix the root cause of the overextrusion
It your part is bumping on the print head, its likely either curling on the top or you are over extruding
Have you ever tried to do a slicer flow rate calibration test?

I have not tried the calibration test. I’ll give that a try.
You can try adding z-hop. Sometimes gives a little more protection against running into things. It doesn’t necessarily solve the underlying problem though.
