  • The Bed size is roughly A4 (315mmx215mm)
  • This machine will not cut or mark metals directly
  • Will cut and engrave plastics, wood, paper, cloth, rubber, etc
  • NEVER use PVC - it produces poisonous gasses

You MUST attend an induction course before using this equipment or persuade someone else that already has to supervise you.


Use of the cutter is subject to a fee of 50 pence per 5 minutes or part thereof.


Please read our guide on Preparing Artwork for Cutting

Operating Procedure Reminders

  • Place vent tube out of window
  • Ensure cooling bucket has sufficient water to cover the pump
  • Turn vent fan and cooling pump on
  • Check that water is flowing
  • Set appropriate power level
  • Close all machine access doors before attempting to use
  • Red interlock light will only illuminate when all panels are closed, the laser is enabled, and the cooling flow is running
  • You MUST NOT leave it running unattended
  • Watch for fires, stop the system and extinguish them immediately
  • After use allow sufficient time for any smoke and fumes to be extracted before opening the panel

Suggested Settings

NB: If doing multiple passes, do not launch Engrave dialog before previous one has finished, as it will not reset position, and you will need to manually hit the 'reset' position button.

Maximum Feedrate is 500mm/s for engraving, and 50mm/s for cutting, above those speeds it may skip or jump position and ruin your work

Absolute minimum power appears to be between 1.5 and 1.75

Absolute Maximum power should be 18mA on the meter, this is around 7-8 on the dial. do not exceed this value as it drastically shortens the lifespan of the laser tube.
