PlasmaC Fiber laser 1Kw head height control + auto focuas

ohmic documentation is here
linuxcnc.org/docs/devel/html/man/man9/ohmic.9.html

The source for both plasmac.comp and ohmic.comp live in git in this folder:
github.com/LinuxCNC/linuxcnc/tree/master/src/hal/components

You may also be able to modify the plasmac probing to do what I was thinking.

thanks alot,,, i will try it,,, and i will update

okey i have update,,
it seems all good,. except one thing,,
auto foucas motor inside the head is considered as 4th axis,,,and i should adjust it according to the cutting height and material thickness also cutting or piercing,, whats the best approach to fix that

You should be able to configure the focus motor as an axis if you think that will work best. That means that it would be controlled from inside C-code by an axis letter.

But, whether this is a good idea or not would depend on the source of the information used to control the motor.

I suspect that it would be better to control the motor inside HAL, independently of G-code commands. (in very nearly exactly the same way as torch height is controlled with a Plasma machine)

i dont think its good idea,,,
it relies on factors
1, distance between head and work-peace (piercing and cutting have different focuas
2 material thickness
3 speed of cut ( fine tuning)
its better to be configured same as material,, in plasmac

PlasmaC use external offsets to control Z motion.
