Emergency stop is software controlled.
===== Software =====
==== LinuxCNC configuration ====
[[https://github.com/HackerspaceKRK/linuxcnc-config]]
==== Fake PlanetCNC USB adapter ====
Counterfeit CNC USB MK1 controller. Actually, USB fronting part of it (PIC18F4550).
Works with quite powerfull PlanetCNC's software, which is free to use with controllers that have valid license.
Please do not use it if you can.
