PlasmaC Fiber laser 1Kw head height control + auto focuas

github.com/taloot/LaserC/tree/main

give it a try and lets complete building it,
i was so busy,, lately thats why. i did not access so often, regarding the capacitance head u need to use chinse preamp its the easiest

if anyone have development skills. we can rework it together, and add more high end, features. Like Frame, ( drawing a frame while laser red spot on to see the place where is will fit)

Is this thread finished.
I have liked what you have done.
The reason I contact is that there are others ways to do what you have done so well.

Cheers, Ian.

May I ask why ?
This post from Taloot was so good.
Cheers.

i came up with many updates regarding this subject. in all aspects.

i will clarify some point 1st.
i found that the Chinese BLC-AMP which is device convert the capacitance to pwm which is smilar thcad is the best as hardware.
2. using gcode isnt bad at all compare to cypcut (dxf)
it have advantage over DXF. as its 2d.
when using g code u can mill pockets bevels, countersink , also it can do deep engraving aka Sheetmetal stamp
3. the laser source price drop 65% an size become 50% smaller and 45% efficiency,
if anyone want to help me we can complete it more quickly .
because there is some feature need to be add for laser table ,
oh also u can weld using same head, all u need is to replica the whoppel movment

Thanks for the great read of how you went about your Fibre Laser.
I have never used LinuxCNC, but you maybe able to to use this product.
I see you use the BCL-AMP, try the LFS-AP01 capacitive height controller.
This is used on the C02 small laser machines.
Have had it working with 2 THC's.
Unlike the BCL-AMP, it is adjustable from 0 to 10 volts for the head to material sensing.
I had been working on a similar project when I came across the posts on Linux CNC.
Cheers.

This is the Laser Head sensor LFS-AP01 working with the DT-115 comparator.

I assume that only works with metal workpieces? 
it works on metal and non metal, just u need to set that in calibration processes
 

gr8 but use the original BCL-AMP better for u,,
much faster and cleaner signal it will work with u out of box. if u treat it as thcad
