I am looking to install a LA03-3500 450nm 3.5W Blue Laser Module With TTL. This is using a 0~5 VDC TTL control. And I get that i can re-assign the FAN output pins to 5 VDC max.
But could I also just use a Variable DC to DC controller. Using 12 VDC out into 5 VDC into the laser controller? I don’t really want to have to re-flash my Ramps firmware when I switch back and forth from using the router and laser unit.
