Laser Cutter

Posted by Vishnu Easwaran on October 27, 2015

First Franc described about the Laser machine in detail, ie, which laser are we using, which material, lens focus, kerf etc. Then about the works that can be done using LASER namely Vector cutting, vector engraving and raster engraving. Learned abot changing the Speed, power and frequency.
The main security measures are.

  • Dangers of a Laser Class 4 beam
  • Machine has built in protection
  • Do not try to mess or hack the lid. It's not cool
  • Fire
    • NEVER leave a laser cutter unattended. EVER
    • If you ever see an unattended laser machine working: SHUT IT DOWN
    • Check your design against double lines
    • Check your design against heat concentration (can the material handle it?)
Not laserable products:
  • Vinyl
  • PVC
  • Any unknown material
I made a design in Inkscape and then the saved .svg file was copied to the PC connected to the Laser cutter. This has the necessary job control software for the machine installed. The software only runs in Windows (sigh!) so we are forced to switch computers !!. Hopefully in the future FabModule will support the Laser cutter too.
We lasered a cardboard sheet of 3.6mm thickness. By trial and error we determined the cut and engrave speed and power. Make sure that we note down the optimal value in our note books. My laser work
