Have a cnc controller without PWM

[Henryme]

I have a cnc controller but I can't find the pwm terminal to hook up a laser diode, but in the board there is space that is written 10v please I need help will attach a picture of the China controller. All ideas are welcome

Try this:

Looks exactly the same and shows your 10v pin is the PWM type speed control and the AVI/GND are the analog (0-10) type control.

[QUOTE=dazp1976;yes they look alike but the laser already have 12v going into it, and the controller has 10v, won't there be issue. I don't know much about electronics and electricals

The 10v is an input for the PWM to Analog 0-10v converter

Do you need a PWM output or a 0-10v Analog? AVI & Com is a 0-10v Analog output the 10v is an input for the AVI to work.

mactec54, how are you suggesting the laser diode should be connected

What is the laser requirements, to turn it on??

Go to cnc4pc.com and get the little PWM card that you can wire to your current card, it’s really cheap and works great

@mactec54, all it requires to turn on is 12dcv and a PWM

[Henryme]

@CNCMAN172 please do you have have any particular pwm card in mind.

Here is a simple card, you can get matching cables this will provide the PWM signal required by most spindles, lasers, etc.

I’m confused how this card would control a laser? It’s for spindle speed control.

This card lets you control your spindle with PWM and direction signals, as if it was an axis motor. It converts the step signal into and an analog (0-10VDC).

That is of no use what's so ever, he already has a Breakout Board that can do what this does

Thanks to everyone, I Have figure out the wiring to the breakout board.
