I have not been using my XYZ probe for at least a year now, been using the paper method to feel for the Z height. Now when I use the XYZ probe searching for the Z height only, it is too high off the top of the workpiece. I am following the directions in the documentation, but obviously I'm omitting something.
By how much? And double check that you have the correct probe selected under the Probe Type dropdown near the bottom of the Probe wizard window.
I am using the interface and I cannot see any way of changing the type of probe I'm using. The interface shows a reading of 14.00 MM instead of a 0.00 Z reading. Using my tools on hand the actual distance to the work surface.. I measure is very close to 17 MM from bottom of end mill i used for the test. In the past I have used the original Z only probe and that worked great .
It lifts up after probing. Take the probe away, then GOTOZERO After probing, it is at Z14 because it found Z0 (mathematically), lifted up the 9mm of the plate + 5mm clearance so you have some clearance to move the plate away. So, its sitting at Z14 there where it is. About 14mm above the surface. If you expect it to show Z0, then look where the endmill is in relation to the stock. 0 would be touching, not up in the air. That's correct, do mention whether you use CONTROL or Interface when asking for help, or the answers would probably favor CONTROL as its more popular. If we have to assume without info, we'll assume the usual. Correct, can't change it for Interface, Interface ONLY supports our XYZ probe.
Click on the "Probe Type" in the bottom right of the probe dialog As Peter says, there's a retract. The probe routines retract 5mm + the thickness of your probe. The thickness of your probe is determine by what you have set in "probe type" (see above). XYZ probe is 9mm thick (9mm + 5mm = 14mm). The Z only probe is 20mm so the retract position would be 25mm.
Well I must say that all makes sense now. All I had to do was set the DRO for the Z to zero. thanks for all your speedy replies.
