Leetro

The Leetro laser cutter board is a proprietary controller with proprietary software. In the case of Leetro this software is called `LaserCut`. Like most proprietary laser cutting software intended for a specific board it has significant disadvantages and the only open source solutions are attempts at reverse engineering. In this case the reverse engineering is still very minor and scattershot. To the point that there do not seem to be any third party applications that work with the software.

USB Protocol

The usb device is located at vendor 0548 with a PID of 1005

These are sent to endpoint 0x04 and read from 0x88.

Leetro Commands

There are some parsing attempts made through London Hackerspace to decode .mol files, here's a list of the commands and their values:
