Opensource Laser

Contact owners and managers

1–30 of 140

This group is intended for discussions of laser cutters based on open source electronics and software.

Note: Lasers of any variety are inherently dangerous. CO2 lasers are especially powerful and the power supplies that drive them can be LETHAL. This group is intended for people who are 18-years-old or older. By reading, participating and/or performing any construction, modifications, or hacks suggested or linked in this group you agree to indemnify all participants, moderators and owners of this group against any and all damages or injury that may result. That means, simply, that you take full responsibility for your own actions and the consequences thereof.
