BLTouch Reprap 3 - Duet 2 Wifi
-
Running into issues with homing with BLTouch on Duet2Wifi with reprap firmware 3 (not beta)
Probe works. tested deploy and retract.. no problem
When script is run once it gets to this command
G1 H1 Z-305 F1800 ; move Z down until the endstop is triggeredProbe is not deployed, Z does not move and I get this error and then nothing happens
G28 SetPositions called when DDA ring not empty

This is my homez.g
; homez.g ; called to home the Z axis ; G91 ; Lift Z G1 Z5 F6000 H2 G90 ; Go to first bed probe point and home the Z axis G1 X100 Y138 F6200 G30 ; Uncomment the following lines to lift Z after probing G91 ;G1 Z3 F1000 G90 -
I don't see anything obviously wrong here, and is mostly identical to mine:

@Adamfilip said in BLTouch Reprap 3 - Duet 2 Wifi:
G1 H1 Z-305 F1800 ; move Z down until the endstop is triggered
G92 Z0 ; set Z position to axis minimum (you may want to adjust this)In your homeall you need to replace this with a G30. Right now you're using an endstop move command.

That fixed it.. Thank you so much!!
