Hi all
I want to improve my CNC spindle, I bougth a Laser 15w from eBay but I need know how connect it.
the laser has control pwm and I want control the intensity from mach 3 software.
could some one show me how I can wire this laser in my red board BSMCE04 from bit sensor

Well the spindle output on the chinese USB breakout pushes 0-10 volts to the spindle drive/vfd. I think the TTL on your laser driver is 0 to 5 volts? Could be wrong. There is a Laser Drive called a BlackBuck that has good documentation.
This website should have something that you can use to figure it out.

hi Nitrozeus

I think the voltage of the card BSMCE04 bit sensor had 0-10v output, the laser voltage is 0-5v TTL/PWM input.

I try to connect my laser in my CNC but I not sure how connect it.

thanks, Regards

It sounds like Nitrozeus has put you on the right track. basically you need a way to interface your different signal requirements and the Black Buck device looks like the go.
