tangential knife along multiple layer height

@MennilTossFlykune,

Very nice contribution!
The planner could add these z motion steps too. And additional steps if needed.

Maybe someone is interested to write a paper how the tangential module should work within linuxcnc
in a nice TANGENTIAL.md file, that can be included with the source.

Then i can just read the paper and tranfer the workflow into code.

You could look at how myCNC works:

docs.pv-automation.com/quickstart/mycnc-...ngential-knife-setup
It adds the rotations and retracts automatically without touching the G-code, like how you were thinking.

EdingCNC works the same way:

Tangential knife, you need to program only X.Y coordinates and the tangential knife follows, also in circles and lifts automatically up when needed.

All these CAM are dragknife not tangential.
Tangential knife has an extra C axis that is mounted on Z axis to actively rotate the knife.

Oh sorry I wasn't aware of the difference.

Maybe GrblGru with this Extension:  ?
