Z probe switch logic.
I am building a new printer and have just made a retractable
z probe unit.
The probe is lifted away from the switch when the bed
touches but is also lifted away when the probe is in the retracted position.
I wanted to do it this way to negate any sloppiness in the
servo arm. The hardware at least is working very well but am wondering if the
firmware will get upset with the z probe indicating bed touch when retracted.
Im hoping it only looks at the switch during the probing
action.
Also any help appreciated (links etc) about moving the servo.
Thanks
Vince

Either way i hope its like this
...
Ignore z switch (during all other times)
extend z probe
monitor z switch while moving bed
get z position (at various locations?)
ignore z switch
retract z probe
If its something like this there should be no issues.
Are there some gems of info somewhere on servo positioning? Cant seem to find a main wiki on it.
The servo puts very light pressure on the switch via a printed coil spring. See pic. Hoping it will be very accurate..
Thanks for help.
