Laser upgrade

First Sorry because my English not is the best. I will try to explain how install the laser module on I3 mega S.


1.Attach there is the STL files for put the laser module easy on the extruder head (everyone should be design your support depends of the power or size of your laser. Also is included some pieces for install the laser module and an stetic cap.

2.check the picture with wiring sketch. I installed the switch for avoid turn on the fan when is runing the laser and vice versa, so you can select laser mode or print mode.

to carry the cables from the switch to the laser module you can remove the bottom screw on the frame or make a new hole and follow the way of the end stop wires (corner of the frame)


3.In this link you can find the custom firmware Marlin 1.1.9 necesary for use all power in the fan (0) cero port. we will use that port for power on and power off the laser
