    Good day all, fairly new to CNC and Gcode and teaching myself. I was wondering what would be the easiest way to view my work Zero coordinates once I run the probing wizard? Is there a macro tat will display it not he screen somewhere? Apologies if this is a dumb question but I just can't seem to find this.

    After completing the Probing operation, remove the Probe, and hit GOTOZERO to move the Endmill to where Zero was set.

    In CONTROL 0,0,0 is also indicated on the 3D viewer grid.

    Thanks! I’m sorry, didn’t explain myself correctly. I meant zero coordinates in relation to home? Injust want to reliably return to my zero and continue working on my piece after day a day or two

    1) home before zeroing
    2) zero as usual
    3) When you come back, JUST HOME (do not set zero again) - offsets from last zero is stored in EEPROM, all you need to do is rehome and Zero will be exactly where it was

    Got it! Will the zero be maintained even if I turn off my CNC and computer?

    Yes. As @Peter Van Der Walt said its stored in EEPROM. Just re-home and the controller will know where the workplace coordinates system zero is.

    also, in OBControl you can see the machien coordinates if you hover your mouse over one of the co-ordinate boxes
    mouse cursor is over the X box and thr hint tells us the machine cooridnate. mouse cursor not visible because windows ignroes it when screen is captured

    alternately you can display the offsets directly by issuing a $# in the serial console and the controller will reply with the current offsets
    [G54:-100.000,-100.000,-20.000]
    [09:52:50] [ $# ] [G55:123.000,321.000,-3.140]
    [09:52:50] [ $# ] [G56:0.000,0.000,0.000]
    [09:52:50] [ $# ] [G57:0.000,0.000,0.000]
    [09:52:50] [ $# ] [G58:0.000,0.000,0.000]
    [09:52:50] [ $# ] [G59:0.000,0.000,0.000]
    [09:52:50] [ $# ] [G28:0.000,0.000,0.000]
    [09:52:50] [ $# ] [G30:-100.000,-97.000,3.000]
    [09:52:50] [ $# ] [G92:0.000,0.000,0.000]
    [09:52:50] [ $# ] [TLO:0.000]
    [09:52:50] [ [ PROBE ] ] Probe move ERROR - probe did not make contact within specified distance
    [09:52:50] [ $# ] [PRB:0.000,0.000,0.000:0]

    G54 is the default WCS and the rest are normally all zeros.
