Hi all,
What is the status on small single-board computers like Olinuxino and/or
BeagleBoard/Bone wrt. Xenomai and LinuxCNC/HAL?
In particular I am looking for a solution with:
- Xenomai + HAL for real-time PID loops with 1ms thread
- SPI + GPIO for communication with custom made ADC and DAC
Hi Anders,
on the Beaglebone status:
I had prepared an SD image with a 3.2.21 xenomai kernel; literally hours after
it was out it became apparent there is a fatal bug in the 3.2.21 xenomai patch
and it will be retracted
by now I do have a working xenomai kernel based on 3.8.13; however the

YouTube isn't letting me edit the video description. :-(
I finally wired enough of the electronics that I was able to jog the X
axis using LinuxCNC. I'm liking the JogIt pendant. It's very handy.
I bought the larger NEMA 23

Good for you!
I've been playing around with my little Unimat CNC lathe, now that I have
the stepper motors working properly (issue with me, not the technology)

I think I would use the USB port for the purpose because the Beaglebones
employ microSD cards, not SD cards. Maybe
Greetings all;
I think I have a relay config drawn up that will do this, however it will
need a 3rd ice cube, mainly because I was never any good with relay logic
in the first place. I'd never met that critter till we were doing the pan-
tilt-light controls for the Trieste's only trip down

I've been using a 48V switcher (Mean Well) with a 10A stepper driver, but
I'm not happy with the stepper driver so I want to go to a Gecko which is
only 7A, so I am hoping to compensate by going up to a ~60V power supply,
but DK/Mouser doesn't seem to carry anything appropriate for a reasonable
Does your switching power supply have an adjusting pot? I've turned my two
down from 48v to closer to 40v, but maybe they can go up 8v as well?

For the price of a flick of the wrist you might get very close to what
you want.

There are $60 switching power supplies from China. I bought a CNC kit
with the stepper motors and stepper motor drives and the power supplies
and it came with three of these. They're available in 300W and larger
sizes, with little difference in cost.

To wear the rails on a Unimat must have taken a huge amount of use!
Nah - the stepper motor brackets actually needed the beds to be extended in

I would not worry about the supply if I was you. The stepper motor
determines at what current you are running and we mostly run at far less
that the drive rating. The voltage will determine how fast you can go
but if you are happy with the max speed at 48v, you will be happy with
