I have an Ender 5 Using the Marlin thingy. It moves around no problem. However the laser will not turn on. I can control the laser using the manual fan speed control on the printer itself. I have tried adjusting the tool index from 0-6 none work. (Not sure what that was. But I read it on someone else questions)
