RepRap 3D printer as a laser engraver.


Print the STL files and clip on your RepRap Pursa. A 1.6W 808nm Laser was used on the version.
Skeinforge can also generate laser milling g-code. If your laser have TTL control, you can replace the M101 & M103 code form M101 S255 & M101 S0 to control the laser on/ off. You need to connect the extruder heater power supply to the TTL control.
