G28 Z Error: M280: Invalid servo index 3 in M280 command
-
I just installed a Piezo Orion board so the nozzle is the probe. It reacts when I touch the tip, the light changes but I obviously have something wrong in my firmware settings I cant figure out. Getting the error
G28 Z
Error: M280: Invalid servo index 3 in M280 command
When I try to home Z, what am I missing?
It is plugged into the Z endstop connection power, ground, signalMy bed.g file

post your homeall, homez and deploy/retract files? Suspect its trying to deploy a probe for some reason?
-
the firmware was originally setup for a bltouch but I thought I changed everything but apparently not. Here is my homeall.g

maybe there is something in your config override file?
-
i dont have an overide file
-
Ok I figured out I just needed to delete the deploy and retract macros from when I had the bltouch hooked up and that got rid of the error.
Now im just trying to figure out why the piezo does not stop the bed when homing Z now. The sensors led changes when i touch the tip but the duet doesnt respond, the bed keeps moving

@57buick said in G28 Z Error: M280: Invalid servo index 3 in M280 command:
M558 P1 I1
Is P1 correct for the piezo? I thought they used P8 for digital input.
Double check wiring. Are the crimps good? Are they going to the right places?
-
its my understanding you can use P1, P5, or P8 they all should work with a little different filtering?
-
I suggest you use P8 for a piezo.
