Duet 3 beta 3.4.0 b3 | Unable to setup Endstop on toolboard.
-
I have a toolboard configured as board 2 with three endstops in series, X, Y & Z. I have the Z probe set to use the same endstop. The z-probe can be seen to trigger in DWC when a switch is pressed.
However, when issuing M574 X1 P"2.io0.in" S1 i get an error telling me the pin isn't free.
Error: M574: Pin 2.io0.in is not free
This happens even when the z-probe is not setup with M558 P8 C"2.io0.in" H3 F360 I0 T20000
I have been unable to find out why. I have a similar setup using X & Y endstops on a single toolboard, and that seems to run just fine on a different machine.
What am I doing wrong?

@greg_the_maker is this happening even if you have the M558 line commented out in config.g and restart the machine? What happens when you send M558 with no parameters?
-
yes, even with M558 commented out.
-
@greg_the_maker add a G4 S2 before any CAN-FD connected board is referenced in your config.
This error is probably connected to this https://forum.duet3d.com/topic/24984/trouble-assigning-filament-sensor-after-using-pin-for-gpio/5?_=1631544376470

I think something very odd is going on.
Even with no M558, and nothing being assigned to use the pin, I can't assign anything to that pin.
-
@greg_the_maker which version of RRF are you running?
-
@greg_the_maker you can't assign a pin to be both a Z probe and an endstop. If you are using the Z probe in lieu of a Z endstop, then you don't need to configure a Z endstop, and your Z homing file should use a G30 command.
