G30 doesn't reverse properly

PxTPxT
in Repetier-Firmware
Printer: Rostock Max v2 delta

I installed latest 0.92.8 from github and configured to use Z probing. Following the setup instructions at http://www.repetier.com/documentation/repetier-firmware/z-probing/  G31 shows correct state of the Z probe switch when triggered.

I tested G30 by triggering the Z probe by hand just to validate it.  When I hit the probe, the Z motor reverses as expected but X & Y continue to move down until the effector crashes.  This is a delta printer so all three motors should reverse in order to raise Z height.

What am I missing here?  Configuration.h is here: http://pastebin.com/60J5PS4t

    I should say that homing and all other manual moves work as expected.

    Just tested with latest 0.92.8 on my delta and it still works as I expect. What happens if you run G30 P0 so no offset is added and there is no xy move to expect. Maybe you have z probe offset in eeprom set to high values and that is what you see.

    I did clear the eprom before updating the firmware.  With P0 the movement works as expected after triggering the probe, but the vertical travel speed both up and down is VERY slow (1 - 2 mm/s estimated).

    2mm/s based on your
    #define Z_PROBE_SPEED 2

    Thanks, I'll fix that. Is there anywhere I should change the offset you mentioned so that I don't have to specify P0?
  • RepetierRepetier
    P0 prevents activating zprobe offset. So only setting z probe offset would help. But then you are measuring different positions then you think using G32. It is a very complex theme I'm tweaking for 2 years to solve it for everyone, but deviations from the simple solution is always complex.
