Capeless Beagle Bone Black what is needed?

• For example I can't run setup.sh in linuxcnc/configs/pru-examples, because the structure of /sys/kernel/debug/ does not have an omap_mux directory.

Hey Pete

Have you seen the new version of Maschinekit and tested?

In the meantime I ordered some HW to test connectivity..

Hi ... re- BeagleBoneBlack… I currently have a CNC system that I configured many years ago and it has been functioning well. The stepper driver/interface is two 3axis boards made by Compucut. The boards plug into the parallel ports of a PC and I run in DOS in a partition on the PC using the Compucut software. Recently the motherboard auto-toasted, fortunately I had another identical PC in the ‘heap’ and so just swapped the hard drive out of the old to the new and was up and running again.
As I see it when this present one toasts (it surely will) I am reliant on finding another with parallel port/s and all the fiddle of re-configuring and transferring whatever is needed to it.
I am interested in looking at the Linux CNC and running this on a BBB but see no reason to junk the stepper drivers (there two in the machine giving 6axes).
What I would like to know from someone is - what I might require in hardware??
Clearly the starting point is the BBB … but I then need to enable this to output the 5v logic needed by the stepper interface/drivers and a GUI to see what I am doing. I want this as a standalone workshop system independent of my PC indoors (in the warm) on which I create control files, save to memory stick for transfer to workshop system.
The aim is to break dependency on DOS and old computers with parallel ports that are becoming rarer and less dependable, whilst linking to an active community of CNC/Linux, actions which seem to me to have long term benefits.
I see discussion of CAPES and also ‘capeless’ use of BBB in this context. BeBoPr also…
I can’t quite seem to assess what is really needed to create my what might be called BeagleBoneBlake.
Any constructive advise greatly appreciated. I suspect there will be a steep learning curve…
Thanks or OOH Ta! Blake.
