PlasmaC Fiber laser 1Kw head height control + auto focuas

There is one issue that I have just discovered. After PlasmaC senses the ohmic input it sends the torch to zero height which would touch the torch against the material. There is no need for it to do that so I will take a look at it tomorrow.

This issue is now fixed.

2.8 and master. I see the 2.8 buildbot (stretch and buster) is up to date but master isn't yet. You can also build from source

another small issue
i will use 2 pwm to analog convertor (0-10v)
1 for laser
2 for gas valve
is it to linked to spindle control?
if yes can i load 2 spindles?

Adding a resistor and a small capacitor to the PWM output will make it analogue, but only up to 5V if the PWM output is 5V.
Since you are using Mesa boards, you can use normal outputs for PWM but with very limited frequency, so if the frequency is not high the above idea might be useful.
That makes 3 PWM's !
It can be controlled as a spindle but it does not have to be, PWM's can be set on their own.And yes, you can have up to 8 spindles if i remember correctly in LinuxCNC 2.8 and Master.
