Work with probe

The just touching the spindle on my vice I would like to avoid if possible. Have you seen what damage can 2KW servo do? I actually have and it does not really play nice and friendly game. image missing /media/kunena/emoticons/laughing.png

When I touched the nose of the spindle to the vise I was using a pendent and manually bringing the Z down one click at a time.  At the same time I was manually turning the spindle to feel when it started dragging on vice.  There was really no drama at all unless I dropped the pendent or something. I do understand the concern though.

Yeah I do it carefully too but I know myself I would rather keep it automatic and keep me and my short circuit brain out of equation as much as I can.
I think I will try the touching the table solution first (when I put the machine back together and finally source new PC) I think I can do less damage that way.image missing /media/kunena/emoticons/laughing.pngimage missing /media/kunena/emoticons/wink.png

To calibrate your 3-d probe I would mill a piece to a known height, dimension, and location. Then probe that, and adjust your probe settings until you get probing results that match the known piece.

That is not going to give me much since you always touch on the bottom of the ball. That can not give different result then the height of the block.

I was suggesting milling the sides of the block as well, not just the top. So that you can calibrate the sides of the probe.

Right ok, for sides I have precision ground calibrated cal rings. We are fairly well metrologically setup. The only problem was not so calibrating the Z height of the probe but the basically Z position in space in relation to any other tools.
