i am currently building a LaserCutter with a gantry system on a old LectraSystems frame. I have successfully managed to aquire a 75w laser( second attempt, first one came in broken) a power supply, and a improvised control board( salvaged parts from old control board, TB6600 drivers, arduino uno with grbl, chip pc with LaserWeb3). The problem now is that the laser power supply has no instructions, nor any useful markings on it so i can identify its pinout(and a wiring diagram with the arduino uno would be highly appreciated). Can you help me with some suggestions regarding the correct wiring?
Sorry if i posted in the wrong section.
