LinuxCNC on RPI

I have started to post details on how I have been getting LinuxCNC up and running on Raspberry Pi.

I started with Raspbian but soon moved to Arch Linux due to the out of date OpenGL libraries. I will also start to put up details on my development of spiPRU that turns a cheap 32bit 3D Printer control board into a PRU (programmable real-time unit) connected to the RPi via the SPI bus. This then gives hard real-time step generators for the RPi similar to the Beaglebone inbuilt RPU’s.

For <$150 it’s now possible to have a LinuxCNC system!

If making swarf for the least amount of money is your goal, dumpster dived PC is usually cheaper.

Dollars not the main driver. Size and the challenge to get it to work. Always need a challenge to keep the interest going.
