The laser cutter have a GRBL controller with arduino nano , and a 45W CO2 laser tube. All the electronics are made by me. Including the laser power supply with high voltage transformer, the main power supply(36V/20A) and the stepper drivers. The mechanical part are cut and assembled by me, i have used 20X20mm AL profile, for gantry a V-groove profile , freon cooling for sub-ambient water cooling of laser tube, and plexiglas for external case.
Here are some pictures with my laser cutter:



In the near future i want to make myself a laser powermeter.
