grblHAL 2k breakout board holder

Breakout board holder to mount in electronic box, i use mine for PrintNC CNC machine.

grblHAL is an open source gcode interpreter that runs on microcontrollers. It is a 32bit fork of the original open source grbl project, which doesn't have the power or features that modern microcontrollers allow. grblHAL is under constant development and the creator Terje Io is very responsive to feature requests and bug fixes.

grblHAL and Grbl allow you to use an external microcontroller to generate the step pulses and other control signals for your CNC machine, so you don't need to worry about the connected PC being fast enough to control the CNC machine without losing steps or other interruptions. grblHAL generally runs on relatively low cost and open source hardware, and is a fast and inexpensive way to get a hobby CNC machine up and running.

grblHAL also allows you to switch between different “sender” software for different features or tasks, as the sender computer doesn't directly control the CNC machine's motors, spindle etc.
