I Need help in Updating my Laser module #448

Open ARCHITAIT opened 6 years ago

ARCHITAIT commented 6 years ago

Hello All, I need your help with something I am trying to upgrade my laser module on a Chinese CNC laser engraver 3000mw to a 15 w laser module

what i am facing here is that the new laser has a 3 pin ( + , - , PWM/TTL ) and the board on my CNC has only 2 pin (+ , - )

is there a way to connect the Laser to this Board ?

i added to thix dropbox link a photo of my 15w laser driver https://www.dropbox.com/s/wxow68moblyfwma/15W%20driver.jpg?dl=0

and this is my CNC controller photo https://www.dropbox.com/s/l7b4kcbpix4bgpq/CNC.jpg?dl=0

please note that i am not an expert in electronics, i know few things about PWM and building basic circuits .

Thanks !

I have a laser with a similar controller. "+" and "-" pins are for 12V supply. "PWM/TTL" should be connected to D11 on the Arduino. You can simply solder to the corresponding pad on the back of the board.
