BLTouch G30 works, homing is not?
When I run G30 P2 It correctly probes, does two attempts, and everything works fine. When I try and run G28 or home through TS it will it the probe, back away, hit the probe a second time, stop, then ram the bed up at homing speeds. Not sure why? I have tried adding delays, different Z homing rates (20mm/s, 5mm/s) all behave the same. G30 Probe works perfect so I don't think its a wiring or connection issue. I'm guessing some timing issue with the BLTouch as I do notice during a probe it quickly jumps back after hitting the probe. During homing its slower to jump back before hitting it the second time. I tried higher Z Feedrates with no luck. Any ideas? BLTouch v 3.1
Thanks

I'll update on my findings tomorrow but any tips would be appreciated :-)
zBedOffset is in eeprom called "Coating thickness [mm]" and only used during z homing to adjust coating in case you have an inductive z probe or you want some z correction to make filament stick just as you like.
Extruder z offset of first extruder also should be 0.
While I'm in the code, I might look into trying to use the same exact motions as a probe for the a home. It seems smoother. I don't really like using the Z home speed and it doesn't seem to drop the be as nicely between multiple probes during home as it does in a probe.
