    Is there a way to make the 0,0 location of the g-code be somewhere other than the bottom left corner of the safe area? I have some parts that I would like to be able to manually align the tool with some hole on the part as my reference point, including cuts that are at a negative X and Y from that reference point.

    There is no way. This would be a major code change and I'm not going near it.
    What I would do is do a drawing for an alignment piece that when attached to the existing part (pins in the existing holes?) gives me a bottom left corner with which to align 0,0. Set 0,0 there, remove jig, set Z0, cut.

    Alternately one can kinda hand code the offset....
    Measure on your drawing from 0,0 to your hole, say it is X1.4 and Y2.3
    Now align your tool there, but instead of setting it as 0,0, set it as 1.4,2.3
    If your CNC driver won't let you do that, set the hole as 0,0, then do an MDI command of
    G00 X-1.4 Y-2.3
    and then set 0,0 at that point.

    Ah, so this isn't as simple as skipping the code that checks to see if a cut is inside the safe area?

    Thanks for the ideas on manually offsetting the tool.
