New Config, issues with homing.

I did check one of my known good configs with a shared home/limit before my last reply. It uses a negative latch velocity.

(units are metric)

Latching happens so quickly its hard to see what is going on. Sometimes I've slowed homing velocities right down (to 10% or less) to troubleshoot.

Just checked some 15 of my old and new configs, luckily i found one where search is positive and latch is negative (on Z), all others are same direction.

I checked another config of mine and it was positive.

I wonder if the sign matters? I don't have the machine anymore to check.

Actually, the sign does matter because I have had machines where one side of the gantry does not home until the sign is flipped!

Maybe i was not detailed enough, all configs have search and latch velocity positive for both, OR negative for both, plenty of those configs, only one has one joint where those two values are not the same direction.
To be more helpful, use Rod's advice and slow down everything to a crawl so you can actually see what is going on.
Before that, do absolutely make sure the motor direction is correct.

Welp, homing switches were 100% inverted.

Homing now works on Z and Y, I have a wiring/driver/stepper issue to diagnose on X.
