Pirahna 1060 Laser Cutter

Introduction

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 15mm thick), MDF (up to 10mm thick) and Plywood (up to 12mm thick), pine board (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
27th August 2019 Fully Operational Power limit raised to 90% as this tube seems a little weaker than the old one and we're willing to wear it out faster.

Suitable Materials for Laser use

List of suitable materials for use with the laser, please note that the maximum cut thickness is only a very approximate guide as materials vary greatly and you may not be able to get anywhere near these figures with your material. The power limit on the laser can be removed enabling 100% power, but as this drastically shortens the life of the tube it will only be done in exceptional circumstances where no other technique can work. If you think your job qualifies speak to any of the laser maintainers about it but exceptions are very seldom granted and you'll have to show why no other tool at rLab can do the job and why commercial services cannot be used.

Material Cut? Etch? Max cut thickness Notes
Acrylic (PMMA,Plexiglass) Yes Yes 15mm Cuts very cleanly, leaves white powder when etching
Plywood Yes Yes 12mm Older/reclaimed plywood might produce toxic fumes. Laser-rated ply cuts cleanest and deepest
MDF Yes Yes 10mm Older/reclaimed MDF might produce toxic fumes. Laser-rated ply cuts cleanest and deepest, some MDF's are treated with fire retardant and MUST NOT be used with laser
Cardboard Yes Difficult N/A High fire risk, must be cut quite quickly and watched constantly
Steel No Maybe N/A Some steels can just barely be surface etched, engraving or cutting is impossible
Aluminium No Sort of N/A Anodised surfaces can be marked, the metal can't be cut or etched at all
Other Metals No No N/A Copper and Brass cannot be affected at all by the laser and may harm the laser cutter

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 172.16.0.100
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.

Not Enough Extend Space error on the laser panel You have the workpiece too close to one of the limits of the laser and the head does not have enough space to move around and complete the job. Move your workpiece a few millimeters away from the edge of the machine and re-run the job.

Planned Upgrades

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

  • Add dynamic auto-focus system apparently supported by controller
  • Create long-focus lens system for deeper cutting

Recent Changes

If you make any non-trivial changes to the Pirahna 1060 or perform maintenance please note it here, delete records older than 1 yr

  • Air lines cleaned, air filter and spark catcher cleaned/replaced. Lens replaced. Stever (talk) 13:21, 2 October 2019 (UTC) & JMF
  • Optical path realigned, frame distortion checks made but without conclusive result, air filter changed. Stever (talk) 14:56, 26 August 2019 (UTC)
  • Mirrors realigned, water changed and new filter fitted, frame leveling continues to progress. Stever (talk) 14:46, 23 June 2019 (UTC)
  • Mirror 1 and Mirror 2 realigned. Mirror 2's top adjuster's locking ring, found to be completely undone, presumably from vibration. Mirror 1 found to be pointing down, and Mirror 2 found to be pointing to the left. Noted that the Y slider has a slight "hump" in the middle. Ruperte (talk) 11:42, 6 June 2019 (UTC)
  • Water changed again and new water filter installed to hopefully keep biofilms at bay. Aiming laser aligned and made functional. Main beam alignment checked, slightly out but will not be adjusted yet to allow for frame settling. Stever (talk) 18:33, 12 April 2019 (UTC)
  • New tube fitted and aligned, coolant replaced and cooling system cleaned, aiming laser installed, desk modified, laser feet fully deployed Stever (talk) 02:34, 3 April 2019 (UTC)
  • Optical Path clean and re-aligned, tube is starting to show signs of age, at next re-aligment carefully check beam roundness at all points. Stever (talk) 07:57, 17 February 2019 (UTC)
  • The entire optical path has been thoroughly cleaned and re-aligned. Stever (talk) 17:43, 17 November 2018 (UTC)
  • Ethernet port has been relocated to the back panel and fitted with industrial connector Stever (talk) 18:06, 14 November 2018 (UTC)
  • 3 redundant switches on the right side of the laser have been removed and blanked off, sockets on the back of the laser are now permanently live. Stever (talk) 11:25, 22 October 2018 (UTC)
  • Current control dial has been relocated to inside the laser and locked at maximum since it wasn't being used and provided an opportunity for things to go wrong if mis-set Stever (talk) 16:16, 21 October 2018 (UTC)
