For that particular use-case it might be appropriate to have a PyVCP

This idea does sound very interesting. Now how do I do it?

I did also put a limit3 before it the offset hal component so that it
limited the distance, acceleration and velocity.

I think these have been suggested, but just to clarify (as much in my mind as
anyone else's):
(a) Assuming you decide the Z height is to be 0.1 lower than it is at the
moment, use MDI mode to go to a known position (say X0 Y10 Z20), Step Jog down
0.1 and Home Z to a value of 20.
(b) G92 can
Is there a simple way to add or subtract a small amount to the offset for an
axis. It seems all the G10 commands replace the stored value, What I would
like is a comand that adds to the old one regaurdless of machine position . Is
there such a thing? How hard would it be to make one?
This takes some special work for your g code, but I have done something
remotely similar. What I did was use the G54-59 offset system and G file
subroutines called from pyvcp.
If I have this straight in my mind what you are doing, it would be
something like this.
1. Home to G54 x,y, and z.

One downside to this, is that unless your chosen variable is persistent, it
