    Refer to Coordinate Systems - for someday - lets say 5 years down the line (;

    Normal uses cases never need coordinate systems. But its for advanced uses like this! Thats why I say, dont bother with it, as it just adds confusion

    Peter is spot on @Matt Thorniley, unlike your machine co-ordinates (sorry :rolleyes:) grbl will set your machine co-ordinates zero wherever you switch on - best to ignore them for now. You can use any text editor to delete that G53 line. Set your workplace zero as normal, raise Z 10mm, then run your g-code.

    I tried that once and it just did the same. So maybe shut the machine off and back on, reset 0 axis?

    Sorry @Matt Thorniley, we have helped to confuse you by steering you to @sharmstr's post processor, which puts that G53 line in. We didn't think that you might have a machine without limit switches that would allow you to reset machine co-ordinates whenever you switch the machine on.
    Delete that line with G53, reset your workplace zero (top, front, left of your workpiece) and your g-code should run. You will have deleted the instruction to raise the Z axis 10mm, so do that by jogging before running your file.
    Alex.

    PS - I believe that there is a second G53 line at the end of the file, it might be a good idea to delete that too.
