I connected without level shifter,all work expect that i have only about 50 % of power.
Just still not grab how to put level shifter in line

Yupiii,all sort it out.i have full spectrum of laser power now
PWM signal is going thru level shifter,FIRE pin is going straight from smoothie board
I had problem because reference 3.3v from my board was missing(my jumper was set up to use 5v for endstops,and this is point where i took reference voltage( i use mks sbase 1.2 board)
Im so happy now how everything work,everything mive more quiet and smooth,visicut is briliant and at last laser web working right for me
I still seen laserweb is nit working with smoothie or am i wrong?

@Damian_Trejtowicz move on laserweb2 (I update the link).
If you have the time you can also try Visicut (should work with usb, not only ethernet), and Fusion 360.
So a large choice to enjoy …
Please describe your convertion somewhere, and share the link with the community. (did you kept the pot? (act as ceiling and save your tube lifespan).

I removed the pot(its 2 seconds to connect back)
I tried VisiCut and Laserweb1 and they work fine.when i do full documentation ,included schematics and firmware and config file for mks sbase 1.2 i will publish this
