My printer will be idle and randomly decide that it has been asked to unload. I don't push anything, and I'll try starting a new print some time later only to realize the printer had spit out my filament enough that it'll fail the priming steps, but not enough to set off the filament runout so it'll still start a print.

I suppose on a related note, I should mention that a lot of the newer toolheads/toolhead mods meant for use with filament changers have a sensor AFTER the drive gears, which should avoid that problem
