Hello everyone.

I just updated from Mach3 to Mach4 Hobby while changing to a new PC that will be dedicated to only run my CNC mill.

I've been using Mach3 for 11 years, it has worked pretty well but thought an upgrade would be good.  I have the latest version of Mach4 installed and working.

One thing missing in the newer build of Mach4 is for the probe, missing is the calibration tab/screen.

On YouTube I have seen video's showing that tab and how to calibrate the CNC probe, it shows a calibration screen and how to calibrate the probe using a know artifact, say a 1" master I.D. gauge.

Am I just missing where the calibration screen is, or is it just not there in the newer builds?

Thanks to anyone that can help!
