I just read the data sheet on that plasma cutter www.jscut.cn/product/205_374

and it looked like it can cut 50mm plate. that is awesome. have you actually tried that thickness?

I think i really need to get into this

this is 3 main tabs

i will add monitoring for gas too

any tips will be appreciated
almost i fixed gas and laser operation

but i still have 1 problem need to be solved the best way.
the capacitance need to be calibrated at about 3 mm away from metal
and i want to probe directly to pricing height.
is it better for me to make new THC + ohmic component?

If I understand you want to probe down and when it is 3mm above the material you want it to stop and that will be the pierce height. I assume the capacitive probe will tell you that it is 3mm away.
You could set the pierce height to 0.01 (it wont accept 0) and factor that out with the ohmic probe offset (it will take negative values) in the config panel. If cut height is the same as pierce height then set it to 0.01 as well.

so the probe pin should go high @ the pierce height

if
pierce is 3mm it will be 0.01
cut is 1mm so it will be -2.01

Sorry, I confused myself here.

If you use the ohmic input and your capacitive sensor senses the material at 3.5mm above the material then you would set the ohmic offset to -3.5, then you set the pierce height and cut height to what they should be.

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.

How much does a 1KW laser with power supply and head and whatever goes with that cost?

main part you need
1 laser source price range 5000-7000 usd depends on the brand
2 lase head start from 450 - 1000 depends on brand and power rating also manual or auto foucus
3 chiller 750 usd

there no power supply its build in unlike co2

@taloot
Thank you.
Not bad at all, and since you mentioned earlier the power usage i got even more interested in this.
I am used to old type laser cutters that need 45KW of power for a 3KW laser.

that was yag laser i guess with xenon lamp.. very bad technology

keep in mind u can pay 1000 usd and buy laser welding gun,,, u can use the laser source for weld and for cut
also there is 2 type one with feeder wire .. other not,, just diffused 2 sheet together,
