I have found a number of 'simple' tool setting scripts, but I would like to have one that after Z initially touches the sensor, it retracts a small amount and contacts the sensor again a little slower. By doing this it is taking out any over run of the spindle. I would also like to know how difficult it would be to write in the script to have the Z offset display not only the height of the sensor, but also the retract amount. Lets say that I am using a sensor that is 1.00 tall and I have a retract amount of .25, I would like to see the Z offset read
Z 1.25. Any input would be appreciated.
Thanks, Jim

The Big Tex auto zero does a lot more than what you want, but it does do the double probe, so you can see how it's done.

For you're second question, it depends on what you actually mean. If you're talking about the actual Z offset on the Offset page, then no. The Z offset is the difference between Z zero in Machine Coordinates and the top of your workpiece.
If you just want the Z axis DRO to read 1.25 after zeroing, it should automatically, because that's the position where it will be. You can't force a DRO to display an arbitrary number.
Or, you may be talking about something else completely, because I don't know what DRO would display the height of the sensor, as you said?

Gerry,
Thanks for the reply. As far as the script from Big Tex, I will check it out. And for the second part of my question....all the scripts I have tried will only show the retract amount in the DRO and not the sensor size plus the retract amount (actual Z position above the work piece).
Again thanks for the reply,
Jim

The DRO should show the actual position, which would be the plate thickness + the retract amount. If they don't, then your Z zero isn't set correctly.
