README
Readme.mdLinuxCNC Shield for OrangePi
This repo contains a HW design files for OrangePi CNC shield for making the OrangePi a LinuxCNC machine.
The allwincnc project can be used to do the realtime heavy lifting (stepper control) while the OrangePi does the slower tasks (kinematics calculations,...).
More details about making this all work with a real CNC machine can be found on my blog
Features
- 5 stepper controllers (direction and step signals) supported
- 3 encoders inputs
- Spindle control - both PWM and 0-10 V outputs
- 6 limit switches (endstops, home position,...)
- Probe sensor input
- Stop button input
- 2 power outputs (cooling, ESTOP,...), up to 24 V
- Incidator leds on inputs and outputs for easier debugging
- Up to 15 V inputs protection
- Selectable 3.3/5 V power for limit switches
- OrangePi can be powered directly from the board (dedicated 5 V input) and vice versa.

Questions
How big is the CNCHat PCB?
It measures 85 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CNCHat use?
104 parts, built around the MIC6211YM5-TR, 74HC4050D, BUK9675-55A and S1JL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the CNCHat KiCad files?
From the kajusK/CNCHat repository on GitHub, at the commit this page was made from: the board is hw/CNCHat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CNCHat design in my own project?
Its repository states no licence, so its author keeps all rights: ask kajusK before reusing the design.
