WARNINGS:

  • STYRENE BASED MATERIALS (POLYSTYRENE) WILL OFF-GAS STYRENE – IT IS A TERATOGEN – IT WILL EAT YOUR BRAIN

(styrofoam, foamcore)

  • CHLORINE BASED MATERIALS (PVC PET-G etc.) OFFGAS CHLORINE – MAJOR RESPIRATORY AND REPRODUCTIVE AND DERMATOLOGICAL TOXIN
  • POLYCARBONATE WILL CHAR OR BURN, NOT RECOMMENDED FOR THIS MACHINE – USE WATERJET
  • Clean the lens before you use the laser cutter.

SUGGESTIONS:

  • ROUGH CUT IN CARDBOARD
  • FIRST.

  • DO YOU REALLY NEED ACRYLIC??  IT WILL SPEND A MILLION YEARS IN LANDFILL WHEN YOU ARE DONE!!
  • THE LASER CUTTER IS IDEAL FOR PLYWOOD AND CARDBOARD AND OTHER BIODEGRADABLE MATERIALS!!
  • THE WATERJET IS MORE SUITABLE
  • FOR THE FOLLOWING MATERIALS:

ALL METALS, PVC, POLYCARBONATE, NYLON, PP, HDPE, LDPE, PE, PTFE

  • There is a file on the desktop:  parametersettings.cdr it has all of the colours set and can be used to optimise your cut.

PPI is pulses per inch.
Power is % of 100Watt available laser power
Speed is % of maximum traversing speed.
VECTOR is a line following cut (printed line must be ~0.01mm thick to work).
RASTER is a raster etch (back and forth) good for fill or blocks.
SKIP!  skip this color – useful for working lines that you dont want cut.
For very thick cuts the 4.0 lens is more suitable as the depth of focus is longer.  It will give you a cleaner cut with straighter sidewalls.
The laser’s “toolwidth” is approx 0.5mm in diameter (0.006″). If you’re doing fine work, plan accordingly.
SETTINGS ASSUME THAT YOU HAVE USED THE FOCUS TOOL!!
