hi puppyowners,

i played around with puppy and made a tiny puppy-unleashed iso
including only basic software (editor, shell, puppytools) a RTAI
enabled kernel and EMC2 for playing around with CNC Smile

the system should have about 128mb ram for a hd install
and 256mb ram when running puppy entirely in ramdisk.

its a bit of a hack. as it untars a filestrukture into /root/cnc after
initial booting. and consists of slightly modified 0base... files
and changes to .fvwm95rc during building of the root-fs.

also there is no documentation or source online right now. it was
a bit of a midnighthack and i didnt manage to pack the stuff together
and upload it. ill do that within this week. this is the initial pre release.
other releases may follow during the next weeks.

if someone wants to give it a try, it can be downloaded here:

http://box.hinternet.at/puppy/emc2puppy/emc2puppy.iso

tell me what you think about it.

ill try to answer any questions as soon as possible but am not regularly
online.

I happen to know of someone who owns a machine shop with CNC tools and already considers himself a Linux expert of sorts. I'll try to make this known to him.

I don't know some of the acronyms you used. What do RTAI and EMC2 stand for?

some links and info bout rtai and emc....

emc2 is the all new Enhanced Machine Controller
software and drivers for running g-code (cnc control language)
with various stepper or servo interfaces via realtime enabled linux.
this is where RTAI (Real Time Application Interface) comes into place.

i hope i find a place to get sourcerer. if not i have to create
a "filesystem patch" for i need to get mesa and or hw accelerated X
running for getting the nice gui app axis http://axis.unpythonic.net/index.cgi/
onto emc2puppy.

so i am going to compile python with various extensions and opengl
capable X for puppy.

Very interesting - you know about the Puppy submarine guys?
May I use Robopup or K9 (Dr Who's robot companion - making a comeback in the new series) as a name for a small wiki news link?

no i dindt, but i read the wiki news about it. interesting stuff indeed Smile

the "Robopup or K9" thingy, well, you may use whatever you want.
i just dont see no connection to it, as for now it only has software
for driving some cnc hardware. i dont know of anyone driving a
robot using g-code Smile

its mainly used for drilling, milling, lasercutting
and things like that.

but that may change, im going too look for other RTAI apps and
look if i can integrate them into em2puppy.

emc2puppy will change its name then to something more realtime
like "puppy sit" which is done in a predictable time, with a good puppy.
just a thought Wink

however, right now emc2puppy is just for emc users who want
to test emc2 fast and painless. or programmers that want to run their
RTAI aplikations on a fast and easy to setup environment.

Why would Amateur Radio digital communications require a real-time operating system? It seems to me that implementing a softmodem would be very similar, and Linux drivers exist for softmodems.

edoc,

Reatlime functionality will be merged into the standard Linux 2.6 kernel in upcoming releases, so if Puppy keeps up with the kernel releases, Puppy by default will also be a true Real Time OS - its small footprint should also make it attractive for use in embedded devices.

The 'Machine Puppy' refered to in this thread is included in the VersionsPuppy page of the puppy wiki. The url there points to this thread. However the url in the first post retrieves only a blank page. Therefore a valid download url is needed for the VersionsPuppy page. If anyone has one, please place it on the page:

does anyone know if this is the same as coolcnc, which is based on puppy?

they have a forum at:

This is an interesting project. I've emailed cncuser via pm requesting he check this thread and provide assistance.

This is far beyond my technical capabilities, but it occurred to me that as building a custom kernel to enable EMC2 could be done based on Ubuntu 8.04,

http://www.linuxcnc.org/

and Woof can be both modified to create/work with a custom kernel and utilize ubuntu packages, someone who knows what they're doing could take that approach to develop an EMC2 Puplet rather than trying to adapt the Standard Puppy for that purpose.

And perhaps hmsurat could be contacted for advice. See his post @
http://www.murga-linux.com/puppy/search.php?search_author=hmsurat&sid=828a69dd2b3902a4e172a65dcadac8d8

But this thread should be moved to Puppy Projects rather than remain on the thread pertaining to pets.
