zprobe latches in the "high" state
-
I've got a weird one here. I am switching my bltouch over to a EZABL, but I don't think this is related to that.
I'm using the zprobe header. As far as I know, I should be able to get the state to change with a jumper wire between zprobe.in and gnd with a probe type of 5.

;G31 P25 X0 Y-41 Z2m119 when triggered and latched
Endstops - X: no endstop, Y: no endstop, Z: no endstop, Z probe: at min stopBecause the state was stuck as a 1000 value for the z probe, I tried a jumper wire. If I boot the board with no jumper, the zprobe=0. If I connect the jumper, it switches to zprobe=1000. If I remove the jumper, it stays at 1000. Am I correct about this assumption? Or is zprobe.in expecting my zprobe to provide a high signal instead of grounding it and maybe it's just floating on startup?

I figured it out! If anyone else runs into this, in the M558 documentation it mentions in one spot that the zprobe pin pull-up is disabled and it needs to be enabled with a ^
