The Laser cutter we've got at the London Hackspace has very crappy windows software so I've started reversing it.

I've got the usb protocol mostly done, I can upload, list and delete files on the controller, there's a few more commands that can be implemented, but they aren't critical.

I've also (after years of not getting round to it) started using Mercurial and I've setup a repo, which you can find here.
