    Not sure why I’m having to reset controller and re-Home between each job file.

    (power up machine)
    g28.2 x0y0z0 (home)
    G28.1 (set G28)

    (position to new zero and set)
    G92X0Y0Z0

    a Vectric/Cut2D job file

    G90
    G17
    G20
    G64
    G0Z0.5010
    G0X0.0000Y0.0000
    M3 S18000

    G1Z-0.0625F10.0
    G1Y11.0000F20.0
    X11.0000
    Y0.0000
    X0.0000
    G1Z-0.1250F10.0
    G1Y11.0000F20.0

    (etc…..)

    X0.1524Y10.8701
    X0.1476Y10.8637
    X0.1423Y10.8577
    G0Z0.5000
    G0Z0.5010
    G0X0.0000Y0.0000
    M30

      If I were to re-run the same job file, machine moves to unexpected position.

      I’ve posted my controller settings:

    The values of $nPM look strange, lots of =0, ?

    You firmware is way out of date, current Master has been quite stable – fw=440.18.

    I think your parameters are OK, with exception of $nPM, but power management did not work well back at 435.10.
    You may be losing your zero position as the job runs.

    After running the job one, enter a G1 X0Y0Z0,
    does machine move back to your zero point?

    PS
    Please report settings in mm.
    Best to enter parameters in mm as well, then w=switch to inch if you must.
    There are many inch related bugs in old fw.

    Thanks again.

    (After running the job one, enter a G1 X0Y0Z0, does machine move back to your zero point?)

    It returns to G28… Not the zero point set via G92.

    Discussion would be a whole lot easier if G code had line numbers.

    Your posted parameters show all G92 offsets =0
    I guess you snapshot that before your G92?

    At any rate, you may have stumbled on a bug that was found and fixed between FW 440.14 and 440.16.
    Other fixes were added and FW440.18 made Master.

    Upgrade your FW and try again.

    Have upgraded firmware but still unable to run a series of jobs without re-setting board, re-homing and re-G92ing. If I run a Vectric cut2d file twice, on second run z axis moves up until trips limit switch.

    So you are running FW 440.18 or FW 440.19?
    Sending Gcode from CoolTerm or from Chilipeppr; if CP, what SPJS version?

    Any chance the M30 behavior is impacting you?
