Re: [Emc-users] Beaglebone and MachineKit

The problem with the boards are that they are a little too general purpose. So much more is needed above and beyond isolated outputs or inputs. For example, say you want RS485 for the spindle controller. Or maybe CANopen CAN bus for pick and place tools to bring in raw material and remove

Re: [Emc-users] Beaglebone and MachineKit

I just looked. That is a really nice way to design this. At first I thought "Three boards? Why?" but this gives you some flexibility to change out one board and also you have some packaging options too. One thing I want to point out is that anyone here could have this PCB made for 40 cents

I used a 3 board solution on my BBB before switching from MK to Linuxcnc. https://github.com/ozzyrob/pp_cape https://github.com/ozzyrob/pp_bob_input https://github.com/ozzyrob/pp_bob_output The cape attaches as normal and the 2 other boards sit either side connected by a short ribbon cable.

This is NOT a "Raspberry Pi" thing, not even a "Linux thing" asking to run an executable is specific to Debian Buster. I think Debian must be a distant 6th place among operating system running on Pi. Raspberian is #1 by far, then a couple of versions of Ubuntu and then Debian.That said,
