Hi All ,

So I bought a IR probe from Aus3D and it works fine. Their selling point was it triggers from 3 mm above the nozzle so no need for a servo.

So it homes the Z with about 2 mm to the surface but I’m trying all the offset workarounds like G92 Z2 but it doesn’t seem to move it past the trigger point. I suspect the probe is disabling the Z motor because it is an endstop after all.

Should I comment out the endstop mask for the Z and will redeem still know what input to look for when probing?

If you want it to be a z-probe for bed calibration, you can activate and deactivate it as a part of the g31/g32 routine!

I have the same issue. I’m not sure if my probe type is set correctly the M558 description in the wiki is not very clear. whit this macro it works fine for the probing. but when I start the print it act as an end stop and don’t apply the probe offset.
my macro have surely something missing.
my g29 macro looks like this:

I have a IR and use the G32 to enable and G31 to disable the Z2 enstop
g32 =
M574 Z2 x_ccw,y_ccw,z_ccw ; activate endstop

g31 =
M574 Z2 ; deactivate endstop

you need to make sure the motor direction is right for you ie ccw or cw

Are there working examples of config files using an IR probe for the bed calibration and z-min endstop ?
