    I'd list up your control type/make also, as much of the 31 & 31.1 are parametized, to my limited knowledge. Hopefully someone with a similar set-up could help out to compare those params with yours and get you going.

    the program is restarted using Option 3 and it does what it says it does which is to keep original coordinate system. this is correctly shown on the absolute coordinate display on the monitor.
    but when axis position is read using Axis Position Variables the absolute position is not recorded correctly.
    what is recorded is the position prior to the the JOG???
    at this point i will have to run two separate programs, one to calculate the center of the circle (x & y) and another get the z position. bummer...
    i suspect this is my error, but i just can't seem to figure it out...???

    Option 3 will cause the tool to remain at this current position, the tool
    coordinate system will remain at its original position, and execution of the
    program will continue.

    good idea

    machine is a 2007 VMC15 with CNC88HS control. i believe it is the latest revision, 1400-5C for the main cpu.

    I assume you have the Fadal touch probe manual not sure if anything in there will answer your question https://itscnc.com/images/Sect_15_Touch_Probes.pdf
