Laser Cutters

Summary

The laser cutters use high intensity collimated infrared light to cut and engrave various materials, the Artifactory has 2 of these machines for member use.

The LG500 and the LC1290 nicknamed “Little Red” and “Big Red” respectively.

The laser cutters are very dangerous tools that are capable of severely damaging both themselves and anyone using them if used improperly, as such they are not to be used until you have completed the safety induction and been trained in their use.



Hazards

Class 2 Laser Equipment
Do not stare directly into aiming beam.
Class 4 Invisible Laser Radiation
If panels removed and interlocks defeated.
Potential Fire Hazard
Ensure cutting bed is clear of debris and compressed air assist is operating.

Usage Costs

To cover the cost of replacing the laser tubes as well as power and other consumables the Lasercutters have small usage fees

Big Red Usage Costs MEMBER RATE $0.20 per minute of cutting time with a minimum payment of $1. CASUAL USERS must pay the day rate plus $5 per 10 minutes rounded up to the nearest $5. You must be Artifactory Trained to use the laser cutters.

Little Red Usage Costs MEMBER RATE $0.10 per minute of cutting time with a minimum payment of $1. CASUAL USERS must pay the day rate plus $5 per 10 minutes rounded up to the nearest $5. You must be Artifactory Trained to use the laser cutters.

Please pay for laser time via bank deposit.

Trainees

Trainees have been inducted into the way of the laser cutter and may use them under supervision of Operators or Trainers. To become a trainee you should approach a Trainer and get some test projects started. Trainees can use the laser cutter they are a trainee for under the supervision of an Operator for that size, or a Trainer. Use of a laser cutter they are not trained for must be done under the supervision of a trainer.

Operators

Operators are users that have completed a number of laser cutter projects and has shown sufficient proficiency to be allowed to work the laser cutter unattended provided they stick to approved materials. Operators can access the laser cutter keys. Operators are initially approved for the small laser cutter only and must still be supervised for the large laser. After an unspecified time they will be approved for both.

Trainers

These are experienced and super experienced laser cutter users, able to clean, calibrate and extinguish the laser cutters. Trainers are the ones that the new users must approach before they are allowed to hump use the lasers. Trainers must trial and approve cutting of new materials.

Specifications

Machine Working Area Description Power / Feedrate Reference
LG500 500×300 (honeycomb area is 485×285) http://www.wklaser.com/pro_183.aspx

LG500 Parameter Reference
LC1290 1200×900 (honeycomb area is 1165×862) http://www.wklaser.com/pro_190.aspx
Larger machine, more laser power and working area but less capable of fine work.

Materials are available in pre-cut sheets to fit in the LG500

Instructions for Use

Laser Checklists

These are little checklists operators should be working through as they go about their laser cutting jobs with each machine.

LaserCut Software

The software which drives both the LG500 and LC1290 is called “LaserCut” and can be found on the desktop of the computers linked up to their respective cutting machine.

A PDF of the “LaserCut” Manual is available from the Leetro website. It's not a fantastic piece of documentation, but may be useful.

Please don't alter any of the machine settings without checking with a trainer first!

File Format

The LaserCut software accepts only DXF (Drawing eXchange Format) Files.

Which can be created using most CAD programs out there, The most commonly used ones at the Artifactroy are Inkscape and V-Carve which are installed on the CAD machines in the CAD Room which can then saved in the internal network the PC connected to the laser cutters can access.

Relative or Absolute Positioning

The machines can operate in either absolute positioning mode (The machine will cut the vectors in the position they are located on the outline of the bed in the software) or in relative positioning mode (The machine will cut the vectors starting at the current location of the cutting head).

For most jobs it is easier to operate in relative positioning mode as it allows you to manually reposition the cut much faster by simply jogging the head. Absolute positioning mode is however preferable if you are using a jig to cut or engrave multiple parts. To switch between cutting modes you simply need to toggle the Immediate checkbox, if the checkbox is checked then the machine is operating in relative positioning mode, if it is not then the machine is operating in absolute positioning mode.

Note: You will need to re-download your job after changing the positioning setting in order for it to take effect.

Cutting Extra-Large Sheets

The lasercutters are capable of being opened to allow for the cutting of sheets larger than the normal cutting bed however by doing so the machine can no longer be considered a Class 1 laser device, but allowing potential contact between the operator and the cutting beam radiation the machine becomes a Class 4 device.

To operate the cutter when it is classified as a Class 4 device a certified laser safety officers must be present. Access to the keys that unlock the lasercutter external panels is restricted to members holding certification as a Laser Safety Officer (LSO) under the Radiation Safety Act (1975)

Note that when operating as a Class 4 device (in addition to the above), all doors to the space need to be closed, all people present must be wearing appropriate IR laser safety glasses, and warnings need to be posted to warn people against entering the space. The practicalities of this are left as an exercise to the student.
