G29 causes error
-
Hi all,
The above refers. When doing a X Y and Z homing, there is no issue; but as soon as I try and do a G29, I get 'Error: Z probe already triggered before probing move started'
My Z probe is a pin with a flag triggering an optical endstop - and a servo is used to 'extend' or 'retract' the pin for usage.
Any/all help appreciated!

run M401 before the G29

Thanks, working. Thought it would automatically deploy the probe upon start of G29?

you are right. and it does for me.
maybe you need a delay with G4 in your deploy if it takes a few ms
-
@Veti Thanx will try

Ok I solved it. I mistakenly declared my Z probe incorrectly. Changed it to P5 and now it work as expected....
