Hi guys, I am new to lasers. I have a hobby router CNC that I am retrofitting with a 10w laser. I just did some test runs manually triggering the laser and it looks good. My question is: how do I hook up the laser controller’s TTL input to GRBL?
I am running a GRBL that controls a generic printer port CNC driver board. Do I hook the TTL connection to the spindle enable?
Thanks for any advice! I can’t wait to get going and this board looks like a fabulous resource!
