At this point i didn't feel like baby-sitting the printer, so i disabled the MFM using M591 D0 S0

Here the ridiculously large min/max values begin to show up. I have seen as high as four digits multiple times.

I use 3mm of retraction during a 3mm wiping movement, only when changing layers with a 32mm/sec retraction speed.
