Galvo Laser
About
The space has purchased a 100w JPT MOPA (Master Oscillator Power Amplifier) Galvo (galvanometer scanner) Laser. Galvo lasers can engrave and cut metals.
A galvo can cut 10 to 65 times faster than a flatbed laser. Depending on the position within the marking field, however, the beam impacts onto the material at a greater or lesser angle of inclination. In the case of thicker materials, this slope of the cutting edge is clearly visible.
The MOPA function allows a lot more control and can on metals such as stainless, "engrave" in colour. In reality this is just localised heating to produce heat marks, but it's pretty cool.
Our existing lightburn agreement covers the pro version of the software, so both lasers can be used with Lightburn, however there are significant differences in setup, specifically because of the difference in boards.
You MUST have an induction to use this device.
Do not bypass any of the interlocks or safety devices
Galvos
Galvo lasers use galvanometer scanners (what gives the Galvo laser its name) to direct the laser beam quickly and precisely across the material. Instead of moving the entire laser head, small mirrors (galvanometers) rapidly adjust the direction of the laser beam. The marking field size is defined by the deflection angle and the focal length of the optics.
Danger Will Robinson!
This laser can and will take your eyesight. Even the £300 safety goggles you can buy only afford you 10 seconds of protection. Next to the lathe, the Galvo Laser is one of the most dangerous tools in the hackspace. You cannot use this without induction
Inductions
It is suggested to start with Laser Everything's Galvo Crash Course. This covers all aspects of the machine including setup on your laptop if you want to use your own lightburn instance.

The rest of the induction will only cover the safety aspects of using our specific machine at present.
Accessories
There is a rotory table with the laser
The bed takes M6 threaded bolts for 3D printed jigs and the like.
Machine Storage
The proposed space for the machine to live is in the CO2 laser room. It needs to be wheeled to the metal workshop and connected to the extractor as metal fumes are not good to breathe in.
Do not use the machine or operate the fan between 10pm and 8am.
