Z height adjustment

[newtocnc]

Hello everyone,
I like to change Z values from a user DRO,
without affecting the G code and rerun the program
Can one do that in vb.
I cut thin uneven parts. sometimes I need to do several cuts,
to get it right.

Thanks

Hello john,
I did similar task (engraving in uneven parts with minimum engraving depth, but all within the material) by the help of limiting z depth. The G-code contains a much too deep z value and by limiting z to e.g.-0.10 and slightly increasing this limit (-0.15, -0.20) I got the required result.

THanks Holger,
That approch work quite well.
I was hoping not to put max Z value in the code.
Sometimes one forgets to click the Z llimit function,
that is when the fun starts.
thanks
