XYZ probe wiring

morgoth90

I have a xyz probe that act as a switch and I'm planning to use somethig like this to find the center of the hole:

; Find center of cavity
M675 X R2 F300 K0							; Find center in X axis
M675 Y R2 F300 K0							; Find center in Y axis

I already have microswitches as endstops on the minimum of the axes.
What pin should I connect the probe to and how should it be configured?
Does M675 expect the probe to be set for both the minimum and maximum of the axis in the configuration or is there a way to specify one pin as a probe for multiple axes?

(I'm using a Duet 3 6HC with a raspberry SBC)

Nevermind...
for some reason I didn't see that the P parameter specifies the probe to use

@morgoth90 See the Ooznest documentation. They plug it into the E0 endstop input on a Duet 2. https://learn.ooznest.co.uk/Guide/Assembling+Your+Original+WorkBee+XYZ+Touch+Probe/61#s309
So any free IO header on the 6HC will work fine, wired as an endstop. You may need to define it as a 'Normally Open' endstop, ie with pin inverted with !.
Yes, M675 uses the same probe for all axes.
