Owing to it's dangerous nature, delicate nature, or expense, this tool requires that you be inducted on it's proper handling before use.


Pirahna 1060 Laser Cutter/Engraver

The laser cutter is one of our most heavily used tools, it's a 90W CO2 laser system with a 1000mm x 600mm bed. At the moment we limit the power output of the laser to 68W in order to extend the life of the laser tube as that's the most expensive consumable part of the laser system. At this setting it's able to cut a variety of materials including Acrylic (up to 12mm thick), MDF (up to 12mm thick) and Plywood (up to 15mm thick) and can be used to make a huge range of items from light fittings to jigsaws. Owing to it's expense and delicacy the laser cutter requires members to have an induction before they can use it.

Current Status

Date Status Comment
2nd April 2019 Fully Operational The laser is functioning normally but limited to 75% power to preserve tube life

Laser Troubleshooting

Here's some common issues that crop up on the laser and how to fix them

Symptom Cause Fix
RDWorks is coming up in hieroglyphics Usually means it has managed to crash, and had defaulted back to it's out of the box setup - which is Chinese! To reset it, go to the Help Menu - then to the Language and pick English.
RDWorks isn't talking to the laser RDWorks has crashed and defaulted back to it's out of the box setup At the bottom right, press the what looks like a button, where it says "USB: Auto" then change it to "web", and an IP address of
RDWorks version 8 or later has been installed The laser will not work with any version of RDWorks after version 7, make sure you're running the right one
Bed won't rise high enough The head has been knocked and moved upwards, preventing it from focusing properly on thin sheets To fix it home the laser both in the XY and the Z modes, place the 6mm focus block under the head while at the home position, and then turn the knurled ring on the red tube to release the head, make sure to be holding it so it doesn't drop out!

Set the head height so that it's just touching the focus block while in that position and tighten up the knurled ring again, you'll now have the head in the proper focus position and can cut using normal procedure.

Planned Upgrades

Parts and upgrades that are planned/Budgeted/Purchased for in the near future

  • Either reinstate head mounted aiming laser, or add coaxial sighting laser
  • Add dynamic auto-focus system apparently supported by controller
  • Create long-focus lens system for deeper cutting
  • Add auto-aim control laser
