Beaglebone black for 5 axis CNC

by Christine88 on Wed Jun 29, 2016 4:33 pm

Hi, so I built a small desk top 5 axis CNC and now I need to control it. It has XYZ linear axis and AB rotary axis driven by 7 NEMA 17 stepper motors. The A and B axis have dual stepper motor configuration using timing belts and 8:1 ratio. The XYZ axis use conventional lead screws. It's actually very similar to the Pocket NC. I'm going to use a beaglebone black board. So my question is do I need any other supporting circuit boards to work with the beaglebone black to get this thing working?

I'd recommend MachineKit for CNC and BeagleBone:
http://www.machinekit.io/

It is a fork of LinuxCNC that runs on ARM boards like the Beagle Bone Black. There are even pre-configured SD card images:

People will usually get a BeagleBone Cape with stepper motor controllers. Here is a list of capes:

There is the Adafruit BeagleBone Proto Cape if you want to build your own circuits:

Hi thanks for the response. Could you recommend a cape board specifically to run a 5 axis CNC? Specifically XYZ linear axis and A B rotatory axis.
What about the cramps?

I'm not sure of a cape with 5 stepper drivers, but I'd suggest asking on the Machinekit google group:

or the Beagleboard mailing list (this is for BeagleBone, too):
