Hi Thanks for this just starting out with my first CNC machine and I have just been looking into probing this will be most useful thanks for your effort in sharing this Regards Mark
have you tested the runout with a DTI and the probes in the spindle? generally this is the first step to calibrating a probe to ensure that the stylus end is concentric to the spindle rotation. there should be no runout on the rigid probe you have unless it is offcenter itself. the plastic probe will probably see some slight deviation due to the tripod design of the probe contact arm. hope this helps!
Thanks yes I tried this and it was okay for the straight probe but I found with the tripod/stylus it became difficult hand cracking the spindle and because I had already built the 4th axis attachment I though I would try that which would give me more precise measurements. Also, it is a little difficult getting the rigid probe made without some runout.
