How is that possible in lcnc

Hi
I just saw this : "CNC Surface Mapping... ON EARTH!" on YouTube


How could I do this in lcnc?

Thx in advance

I saw that too. Someone would need to make a pyvcp panel for the inputs and have it activate a subroutine. Not sure the correct sequence but basically the subroutine would map the surface and apply z offsets to the appropriate g code.

Maybe you should have a look here:
forum.linuxcnc.org/38-general-linuxcnc-q...leveling-to-linuxcnc

www.scorchworks.com/Gcoderipper/gcoderipper.html#samples

this does something like this, it converts gcode for the curved surface

Linuxcnc almost has this capability (done the way they did) but would need work.
(My hunch based on not even looking at the code )

linuxcnc does leadscrew compensation very similarly.
Leadscrew comp only adjusts the axis it is comparing: ie. looks at axis X adjusts axis X
I don't see why you couldn't add the ability to look at axis X and Y adjust axis Z.
Just need to find an interested developer
adding an official request might help marginally.

I'd like to see a version that uses an Intel depth camera. The camera would take a photo and create a depth map, With the help of the image, touch off somewhere (which may not even need a physical touch) and set the reference plane.. Then as the tool traverses the job, use the depth data for the pixel being traversed to drive a  z axis external offset. Would be cool and a lot faster than probing.
