Aram, LinuxCNC will never run without an OS. Modern single board computers like the BeagleBoneBlack run full OS's like Ubuntu and Debian. LinuxCNC/Machinekit run on top of the OS, along with a real-time extension.
The BBB version of LinuxCNC works fine for driving stepper motors, but cannot yet handle closed-loop servo systems very well, as encoder pulse counting is too slow. Eventually there should be Mesa or Pico type hardware add-ons that offload encoder pulse counting to make servo control possible. I have to emphasize that Machinekit is still very "bleeding edge", and you would be well advised to stick with x86 motherboards and straight LinuxCNC for another year for your machine projects. -- Ralph ________________________________________ From: a k [[email protected]] Sent: Saturday, November 22, 2014 9:58 PM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] single board computer for last 10 years developer put a lot of time to make emc2-linuxcnc to run on ubuntu. now ubuntu gone so all those efforts. for how long Debian will there? single board always will be there. can single board comp. run closed loop- ac-servo motors? can single board comp. use existing hardware -boards- etc? how far in the future linuxcnc on single board computer. (closed loop + servo motor+ use existing board) month or years away?
