The Y axis failed during a probe test (yes, the Z axis has a probe fitted, kinda). After a bit of poking around, I found the Y axis drive screw was jamming. I wonder why? Let's pull it out and have a look next to a new one:

That is what we in technical circles call "well shagged, mate." I'll replace it and resume probing, but I think the issue here is the screw resting on a plastic bearing hole, which is dragging plastic into the thread, filling it up, and causing excessive wear. I hope the drive nut is ok.
Edit: The Y axis has now crapped out and only has 1mm of travel. At this point I'm tempted to begin the Alpha Prototype XY stage.
