Also - I'll check to see if the shafts bind at all from front to back to test to see if they're out of round....thanks.

I'm wondering if your belt teeth slip every so often due to trying to pull the filament and that is racking it backwards.

Just print a 90 mm tall rod that is about 4mm round with a brim at the base to make sure it stays stuck on the bed, if your looking for something to test with that cost less in plastic. Even if my guess is totally wrong on what the cause is, at least you'll have another test to look at to find the issue.

I have seen it somewhere in a previous post. I do not know what the procedure is to fix it, but being that you are still on xyz firmware, maybe it is fixable thru them

I'm running firmware "G", with a spool of White Octave 1.75 running 120 on the bed and 215 on the extruder. Filament is coming down from above, and then back in the back crack of the box and in through the rubber grommet. Tension is normal.

When I printed out this unit, it was offset, continuously, towards the back of the unit. I've since gone back and tightened the belts (taught, make a "hum" sound when plucked), and run a calibration with a dial gauge unit on the bed (within .005" across the bed).

What I don't understand is that this looks "curved" like a slow drift upwards.

I printed out the replacement bearing block from this forum this morning after all of that, and the "curve" exhibited on the first vase, that was progressively towards the back, is showing on the bearing, only this time on the left side of the housing. The right side of the housing has a vertical wall perpendicular to the bed....the left side sort of "sweeps up" and flares out as it goes up.

What could be causing this, and how can I test without printing $20 of plastic every time or committing to a large model?

Humbly submitted....
