BLTouch Failed to enable endstops error on home
-
I recently upgraded the duet firmware from 2.05 to 3.0 then 3.1.1 and I'm now unable to home Z.
When I run G28 Z I get: Error: Failed to enable endstops
Also, it used to move to a probe-able location before deploying the probe. Now it just errors.
I'm using a bltouch probe and my wiring matches
https://d17kynu4zpq5hy.cloudfront.net/igi/duet3d/KUDxTZSs3rnd3JVH.fullI'm able to deploy/retract the probe using
M280 P0 S10 ; deploy BLTouch
M280 P0 S90 ; retract BLTouchHere's my config:

Thanks for your help

Figured it out. Had to make some changes to homez.g
G91 ; relative positioning G1 H2 Z5 F6000 ; lift Z relative to current position G90 ; absolute positioning G1 X0 Y60 F6000 ; go to first probe point G30 ; home Z by probing the bed
