Mini 2 Z not going down far enough... ever

I had a bad jam of filament and had to take apart my hot end to clear things out. Ever since, bed leveling is always failing and not even ever touching the washers.

I have connected via USB and manually controlled things to try to lower the Z as much as possible. I can never get it down as far as a washer or the wipe pad.

(I have the magnetic bed, so this is adjusted from the default.)

Furthest I can ever get things down:

Any ideas?
