Detla probing adice - inconsistent correction still on delta
@repetier - could you point me in the right direction on this damn delta of mine? I've read the guide for z probing, and think i've followed it properly.
I'm getting inconsistent results and correction on my delta after a G32 s2.
the probe on the delta is using the allen key method which activates a microswitch on the effector.
probe tip sits at 8.5mm from the tip of the nozzle when it's deployed, so this is the value i put into the configurator (Z_PROBE_HEIGHT).
whats happening is that it goes and probes happily and computes a rotation matrix for correction - but the nozzle sits right on the bed during a G1 z0, and autolevelling while printing either pushes the nozzle too far down in some areas or sits about right in others - as if the matrix is either inversed or the probe is measuring incorrectly ?
Do i need to enter a value into Z_PROBE_SWITCHING_DISTANCE to compensate for the travel of the probe to change the switch state ? (this is currently set to a value of 1.2mm which is the best i can measure).

probe height from nozzle (8.5) - switch movement(1.2)).
I will set the Z_Switch_distance to 1.5.
As always - thank you ;-)
Could I have missed something ? Does the sampling grid need to be orientated specifically on a delta ?
