A couple parts I made to adapt a Cube 3 for laser engraving. It's not an easy task but someone asked so I've uploaded this stuff.

The wheel turns the laser off when the filament would normally be extracting, the red button is a manual override to turn the laser off.

before installing the laser you need to set z axis near the bottom, do this by laying a 6X6" piece of typing paper on the print plate and when auto set z axis fail you will have the option to manually set it.

For the bracket to be held securly I used zip ties on the left side. The bracket needs to be designed better, it's just a prototype for the neje 30 watt laser.

Finding a way to switch off the laser during a move to a new location was the most important, the little wheel wrapped with 3m double sided tape it works great.
