alex_joni: you said a while ago you had some packages for 6.06 to test out?
fenn_shop: I think you can use cradeks script - just change the breezy to dapper
in the file
that is how I did it initially anyway
hmm. Binary files emc2_2.0.1_i386.deb-breezy and emc2_2.0.1_i386.deb-dapper differ
but i bet apt doesn't know the difference
yes they're very different
that's why they're in different repositories
I think you upset him ;)
there's two of him, looks like I only upset one.
nah i'm rebooting to get the kernel installed by emc2.0.1 dapper
fen_shop is his alter ego
i'm totally ignorant about what is different between dapper and breezy
anyway i still get the error message: insmod: error inserting '/usr/realtime-2.6.15-magma/modules/rtai_hal.ko': -1 Operation not permitte
look in dmesg for the real error
lots of unknown symbol errors
RTAI[hal]: ERROR, LOCAL APIC CONFIGURED BUT NOT AVAILABLE/ENA
sure you have the latest kernel? he fixed that
no idea what the consequences of that are
would apt-get remove emc2 remove the kernel package?
i suck at using dpkg
I had that :) - you have to add a parameter to the grub
whats the equivalent of rpm -qa | grep
but he fixed it right?
but yah - I think he fixed it
I am sure he did. the next day I updated the kernel and it worked
linux-image-2.6.15-magma aj2 Linux kernel binary image for version 2.6.15
I think it's aj4 now
apt-get update, or fire up the update manager
[00:44:57] <skunkworks> http://pastebin.com/708927
as of today - (it updated today)
do you also have the latest rtai-modules?
apt-get update; apt-get upgrade shouldn't do anything
how do i specify for apt-get to get the aj4 kernel and not some other linux-image..-magma kernel?
you can specify a version, but it will get the latest automatically
ok, upgrade does want to get linux-image and rtai modules
fenn_shop how did it get the older kernel?
to begin with
how's your hexapod coming?
* fenn desperately looks around for some chocolate
* cradek quickly offers to share his
just ate half of a strawberry cheese cake
bleah, that's not right
it may not have been - but it was good :)
skunkworks: it got the older kernel when i dist-upgraded and apt-get installed emc2 a week (?) ago
ubuntu takes up 5 gigs!! what a pig
but it sure is purdy
if you like the windows-XP lookalike stuff
oh you use gnome
are you using kde?
i hate kde as much as i do gnome
as a window manager
but the applications are nice
alright! aj4 kernel works
sweet - now there are 5 people running it (don't know where I pulled that out of)
jepler, me, you, SWPadnos, alex_joni sounds right ;) cradek has been goofing off
so i guess i'll make a page about how upgrading is supposed to work
yeah though I'm not sure if I'm on aj
I don't know when he did it - I just noticed the update today - I did have it on yesterday though
it's days old, maybe a week
SWPadnos: simple stepper motor question?
ok - I may be able to answer a simple one ;)
i need to reverse a 4 wire stepper by changing the motor wires.
yep. several ways
1) swap the polarity on one of the coils. 2) swap the coils
either will work
so, a1 a2 b1 b2 > just change a1 and a2?
or a1 to b1 and a2 to b2?
or b1 <-> b2
cool. thought it would be easy. thanks. it's a test unit for Lawrence Livermore Labs National Ignition Facility.
err - they're not trying to ignite the whole country are they? ;)
fusion research. this tests a couple of small sub assemblies that have steppers.
no, just a few drops of water or something.....
thanks. my electronic associate is moving a production line from Malaysia to Singapore.
kinda hard to reach for a few weeks.
ah - bummer.
that sounds like a fun job as well
i got the job to replace my client's 'burned up' foam mill. budget is about 75k
unless they want it done tomorrow ;)
gonna try and run it with emc2. 4 axis to start, x y z a.
not tomorrw, about 8 - 10 weeks.
is this a milling machine, or a wire foam cutter?
anyway, thanks again. i'm off to collect a few receivables that are way late!!!!!!
heh - see you
Hi Steven -- ray here
hey ray. How is the trip?
Hi Ray. How's China treating you?
Lots of walking
is that China or the trade show doing that? ;)
There must be 200 different CNC Lathe manufacturers.
almost as large as IMTS
kerry_: bring one back for me .. just a small one
Been trying to get them to put one in my backpack
just starting to get light here.
I found several control makers that are running linux as the motion server.
just for the gui, or are they using rtai or something similar for actual control?
kerry_ is now known as rayh
the gui stuff is ms the linux I'm guessing is rtai or some such.
but I've not been able to get that far into a system.
they are just a bit nervous of me.
I will try again today with one company.
only found one puma knock off and it was demoing flex wireway
and one small part loading arm for a lathe.
What kinds of issues am I likely to face if I use step and direction drive with encoder feedback
rayh: hi there
I'm wondering about step and direction out with encoder feedback.
probably use 5i20 to read encoders
do you mean on steppers?
it probably can be tweaked to work
as long as the encoders only close position/ferror loop, not as a PID
Probably servo motors
but with position control mode to the drive.
oh, so like the G320 / G340
that works great
at least the G340 I tried
Did you use a separate encoder for PC and for gecko?
the only thing that might make you do that is isolation
otherwise it should be possible to run the encoder feedback to both
may need a buffer though
The high end drives I'm seeing will create the pc encoder signals.
ok. for AC motors and the like?
got any $ thoughts for a proper buffer for a gecko
JonE sells a 4-channel buffer / error latch for $100, I think
thats probably on the high side
since a 74ls series part can do the buffering job just as well
I saw jon's board at fest
the little one? (I think I was the first person to buy one ;) )
I just remember him showing me a card and talking about it.
[21:47:39] <SWPadnos> http://pico-systems.com/gecko.html
the other interesting thing it does is provide power to the encoder even when the drivers are off, so you don't lose position in all stop cases
Yes that is a good feature.
so you can truly use your EMC system as a DRO ;)
I've seen a lot of Galil cards embedded in control systems here.
aren't they pretty expensive?
Yes i think so. Have not been able to get a user to tell me how much.
ok, I'm off to bed
see you Alex
rayh: wot for?
the report on the gecko with encoder
oh.. that's nothing ;)
all hail alex
not to me.
rayh: I must warn you that I didn't use them a LOT
I sold a wirefeeder once
and it's still running (1.5 years later ;)
g340 + encoder on the wire
Right I remember that project.
heh.. I still have that pic

* alex_joni is off to bed
bed is good
sure sounds like a good idea ;)
btw, I had no idea the ubuntu live CD would be so interesting
[22:27:05] <alex_joni> http://dsplabs.cs.upt.ro/~juve/emc/.logs/counts/
of course it is.
I put a copy of it on cncgear as well, I think
SWPadnos: quite downloaded
maybe I'll look at making one for dapper
as the install is a Live CD
so you could try it out, and if it's ok.. push install ;)
yep - it's there http://www.cncgear.com/EMC/
not sure if you do have the option to install from the breezy one
I think you do
it SHOULD be.. but I didn't see it ;)
I can't remember
I did put a note on the download link saying that you can install to your hard drive if you wish
yeah, just read it
probably it can be done ;)
I must have been right ;)
btw.. ever heard of xUbuntu ?
and edubuntu ;)
oh, maybe not then
xUbuntu is an PC-/Xbox-enabled version of Ubuntu GNU/Linux distribution.
an - one of those
ah, that was
xfce4 on it .. so pretty close to Xubuntu ;)
XGL should perform well ;)
if it works at all
true. it is an ATI chip in there, isn't it?
* alex_joni has nfc
me, either. the last console I bought was the Turbo GrafX, I think
SWPadnos: I don't like this remark: https://wiki.ubuntu.com/LiveCD
As of Ubuntu 6.06 (Dapper Drake), you can also install off the LiveCD.
I'm not sure if they're referring to the fact that the only graphical install method is with the liveCD
the server disc is a text install, I think
[22:39:10] <alex_joni> https://wiki.ubuntu.com/LiveCDInstallHowTo?highlight=%28CategoryDocumentation%29
I think I installed from your LiveCD onto my laptop or something
doesn't sound like something I would EVER try ;)
and I'm pretty sure I didn't have to use a CLI at all (though it's not that hard for me, so I might not remember it ;)
command line install?
command line interface
that page sounds like LFS ;)
linux from scratch
except the compiling
and the scratching
SWPadnos_ is now known as SWPadnos
guess is now known as skunkworksB
