Do NOT connect to can output unless you have a jtech driver. Most laser drivers expect a 5v ttl input control signal.The fan output is12v. The jtech driver reduces the12v to5v but generic drivers may not do this. If you want to use fan output with a generic driver then it’ll have to go through a voltage divider first. If you are using jtp gear then just follow their instructions. If you’re not then please wait for my walkthrough.I’ll explain everything.
