Y1200 Laser cutter

Intro

Over the course of 2022 and 2023 I built the Y1200 laser, designed by Rob of further fabrication.

You can purchace the build guide, parts list and cad model for $5 each, which is very little money considering how much work went into the whole thing.

Apart from the written docs, he made a series of videos on just how to build the bloody thing. It’s called The laser cutter build series and can be found <— there

Admittedly, the documentation is a bit sparse. This is because I’m writing this after the machine is already built and a lot of build details have been forgotten.
