Is it possible to get emc working on later version of ubuntu that the provided on the live-cd?
even on the ubuntu 9.10 dist?
I don't see why not
it will be a bit of a pita, if it's the first time you're doing it though
well it is =)
but i need a newer dist to get my touchscreen running it seems
pain in the ass atm
this is what I love about linux, the simplicity of things
I'd think getting the touchscreen working on an older ubuntu (backporting the module) might be easier
but I don't know specifics to be sure about that ;)
did you try stock 9.10?
just the live-cd version
that's what I meant
stock = unmodified
live isnt 9.10?
or is it?
the version on the emc cd i mean
thats the one ive been trying
the last emc2 CD is using 8.04
8.04 = 2008, april
9.10 doesn't exist yet (2009, october)
since 8.04 there is 8.10 and 9.04, but not with emc2 on them
but itll work on them+
I would grab one (whichever you like) from ubuntu.com, and try it out, see if the touchscreen is working
ill kick in 9.04
if it's not working.. then there's no point of going through the trouble of making emc2 work on it
might aswell try it

according to this ppl got my screen working in 9.04 so there is still hope =)
but using features not used in 8.04
so its a longshot =)
it works allmost perfectly in 9.04
alex_joni got some time to help me setup emc from scratch? =)
frallzor: that'll take a week or so ;)
in other words, im fucked using touch then? =)
[11:13:57] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Debian_Lenny_Compile_RTAI
that's a pretty recent instruction on how to build a rtai kernel
im brand new to linux, I have no idea what that is =)
or rtai =)
then it'll be "problematic" ;)
is there some way to get 8.04 to handle *.fdi the same as 9.04?
I have no idea what fdi is
somthing to do with hal =P
hmmm what about a virtual machine in win? will that work nice with 8.04 and emc2?
so, im still screwed in other words =)
nope it won't
I mean you can run emc2, but not to control any machine
aka still fucked =P
* BigJohnT goes off for a motorcycle ride
gotten the screen to work somwhat ok but the "resolution" sucks, the pointer moves like an inch at a time
anyone got a suggestion? =)

sometimes i cant find stuff on the wiki, even tho i use the search.
its because its on www.linuxcnc.org, not wiki.linuxcnc.org.
eg: the pyvcp tutorial http://www.linuxcnc.org/docview/html//hal_pyvcp.html.
could the search look for both sites?
Good morning, everyone. I'm having trouble with my mill again.
The issue is a drifting x axis. It is incrementing by 4/10, increasing, then returning a joint 0 following error when it gets to 500.
The mill was just relocated to a different shop, if that means anything.
were a lot of connectors disconnected and reconnected during that move? check for any loose or wiggly connections, check for a good system star gnd and that the mains is the same voltage and capable of delivering the same current. it sounds like noise on the encoder IF its got encoders.
the problem is usually the last thing you did ;) so the move is likely a cause.
Everything was disconnected, but it's back together at this point. I was fearing that it would be a ground loop / noise issue on the encoders.
It's got glass scale linear encoders.
star ground means only 1 path to gnd, this avoids loops. finding a loop is a lot of inspection, but you're limiting the search to the scales.
maybe you got a star for the 5V to the scales, there can be digital analog and power stars.
since the encoders are pretty isolated, you may NOT want to join their returns to a gnd that is useed for other things.
you may want to return them to only their power supply.
you may want to connect the shields to the p/s thru all connectors up to but not onto the final destination ( not onto the scale )

tom3p: if you use the search from linuxcnc.org then it will search both
there's a google search on the left
alex_joni: thx, my bad, i always goto wiki 1st
Well, that is new. The place we're at now has a ground wire with the power; the old place didn't. That's the biggest change.
Famous last words: "I'll disconnect ground and see if that helps."
check that 'gnd' to gnd. look for voltage, look for ac AND dc. look for continuity
I know there are multiple ground connections with the new one. I'm just removing the one temporarily. The problem is that the computer has its own ground, and that's different from the mill's ground.
Add in shielded cables and you've got a loop.
only cnx shield at one end. run it back to it's current source.
That's a little tricky when everything is in grounded metal cases and armoured cable.
are you using the armour as the shield? yes, tricky. usually the shield is fine wires woven around the wires in a cable insulated from the outside world by a plastic jacket covering the cable. this has no connection to the armour. armour is meant to avoid crushing.
i really dont know your situation so i'll shuddup now.
That's okay, I don't really know my situation either.
A lot of the parts and wires on this thing are recycled. It's a real mess in the case.
Well, it wasn't a ground loop.
Behind the AC drive, two of the wires had gotten loose. It was only pure chance that I saw them.
Thanks again; MASEngr out.
who was that masked man?!
woho finally done with my electronics =D
on to the machine

whay ya guys think? =)
Looks pretty nice!
im satisfied =)
I dont see any fuses thogh
hmm good idea
I should add that
easy to fix =)
Is the BRB illuminated? How do you know it's ON or POWERED ?
BRB == Big Red Button
ah its illuminated
the BRB and the power switch you mean?
BRB = brighter when pressed
or it seems, might be optical
but its noticable
I dont see a lot of ventng on that enclosure, any fan in it?
not atm, got a nice 230V to put in
Also, mght want to make sure chips can't fall in too
ill have it where it cant happen so upper vents are redundant
it just came that way =) vents under too
so, how much and effort is needed to get emc2 working in ubuntu 9.04? =)
is there any way to tell "gcc -funroll-loops" not to unroll a certain section?
gah I do want emc2 on unbuntu 9.04 =/
noone happen to have custommade version of it precompiled with emc2? =P
I am Adding an encoder to the spindle on a bridgeport. When in backgear the motor is reversed and the count from the endoder will change somthing like X4. Is this possible
Is EMC able to make the direction change and counter change based on a Limit switch input.
