3DPrinting

This morning I came to work to a perfectly printed set of plates. So I started another instance of the exact same print, went for a swim at the municipal swimming pool nearby, came back to check on it just in case, and it had done the same thing it did on Friday.

This time, nobody was at the office (it's Sunday) so I know nobody monkeyed with the print. Clearly the plate hasn't moved. So those hypotheses are out.

The belts look tight - although the teeth feel a bit chewed up, particularly the table belt. But I doubt this is what caused the slip, as it seems to slip randomly in both directions at the same time.

At this point, I'm placing my bet on the print head coming so close to the edges that it hits the limit(s) when it's unlucky, or it causes the stepper motors' counters to overflow or something - i.e. it hits a firmware bug. The PrusaSlicer software seems very confident that I can print this close to the edges, and indeed the printer does it, but I wonder if it's overly optimistic.

So I bunched up all the plates closer to the center of the bed and re-sliced, so the printer never prints less than ¼ inch from any one edge. Let's see what happens with that.
