Hi all… First timer in here… I’m looking to fit a laser to my CNC and have been looking for answers… I see you’re talking about a Sculpfun S9 which is what I’ve got. Maybe someone can help?
I’m connecting it to a DB25-1205 breakout board and using a 12v power supply to power it.
I understand how/where I’m connecting +12V and PWM pins but I’m a bit unsure about -12V.
Am I correct in thinking that -12V from my power supply runs to the -12v pin on the Sculpfun, and then daisy chains with another cable connecting to the GND terminal on the BOB?
My diagram might explain it better than me!
