After successfully printing 6 non-rounded parts with the Hatchbox filament, I told it to print three round ones, namely a ratchet, knob, and sanding jig. All three suffered catastrophic Y-axis layer shifts. So I switched back to what was left on the Dremel-branded spool, re-generated the gcode, and hit go. It worked… better, except for the jig.
It looks very much like the gcode that the Dremel slicer software generates when you try to print a thin-walled cylinder (like the jig) creates a rapid series of XY zigzag moves that causes the Y axis belt to occasionally skip, ruining all the parts currently on the bed. Why it was clearly worse with the Hatchbox filament may be due to irregular tension from my hand-winding, or just dumb luck.
Good thing I already confirmed that I can get good prints with MatterControl, eh? Sure enough, when the same trio of parts is sliced with that app, the printer never makes that distinctive shuddering zigzag noise, and they all come out clean.
I suppose I should take another look at porting the Dremel material and quality profiles to the current version of Cura, as well. Someone claims to have settings for good results with Hatchbox filament, which is worth a shot.
