anyone here ever succesfully used lim with emc2?
what is lim?
linear induction motor
also called linear motors
EMC doesn't care what kind of motor you're driving, you just need the appropriate driver
as long as the motor driver can take one of the forms of output EMC can generate (step/dir, analog, PWM) and there's encoder-style position feedback, you should be OK
thats a way of asking if anyone ever managed to rig a lim to run with emc2
I don't know for sure
I have been toying with the idea or building homemade lim for a year or two
but I can't imagine why it wouldn't work - for example, Yaskawa uses the same drives for linear or rotary AC motors
heh, good luck on that front :)
true, thats no different than running any servo...
there are a bunch of linear motors on old sat dishes
didnt knew that, any idea where I could pick up some garbage dishes?
true linear motors? or rotary motors driving screws?
you have to get there ahead of the scrap metal haulers they are in peoples yards
real linears motors
ahh well they would be rotary motors driving a screw
* BigJohnT looked up linear motors
something else I been wondering since I have never downloaded before the emc2 live cd. Is Ubuntu coming with all the std utility programs such as openoffice or is it only a clean install for emc?
it's loaded up
OpenOffice, Firefox, Thunderbird, gimp ...
aside from that and the probable fact that the basic loading kernel is rtai, is there any other difference?
* BigJohnT takes back linear motor and replaces it with linear actuator
it has EMC2 :)
since the kernel is RTAI-modified, you need a different package with the linux-ubuntu-modules and linux-restricted-modules if you need to support certain sound, video and wifi chips
those package are not installed by default, so some hardware that works on stock Ubuntu may not work on EMC2+Ubuntu until you install the necessary package
SWPadnos: can I quote that? :)
only if jepler, alex, and cradek confirm it first ;)
thanks for the answer
crap, I lost the remote
I hate when that happens
yep, don't pay attention to FF through the commercials and the wife swipes the remote
incidentally, if you (anyone) decide to get a blu-ray player and you have a 1080p TV/monitor, run (don't walk) to your nearest blu-ray dealer and buy the BBC series "Planet Earth"
what is blu-ray SWPadnos
better DVDs ;)
can you play regular DVD's on a blu-ray
SWPados quoted for truth
if there's a Costco nearby, they should have a good deal on a pretty good player, $200 for a Panasonic BDP30
yes you can
many players upscale output for SD DVDs
nearest costco is in St Louis ... 3hrs away
online then ;)
or have Jon E get you one ;)
ok that would work
oops, it's a DMP-BD30A
I knew there was a 30 in there somewhere
* BigJohnT does another google search
it's not the finest player out there, but it's a good value
most of the reviews I found put it pretty high on the quality scale, and they were talking about getting a steal at $450
SWPadnos: do you have one?
I'm off to start the furnace... the bratty kids are complainin' and its only 11c
I'm trying to decide whether to get an HDFury2 or a new big screen TV
wheres the $$$ tree growin'
my big screen is quite old, and is only "HD-Ready" (ie, no HD tuner), and it's old enough that it doesn't have any form of digital input (FireWire, DVI, HDMI are all missing)
if I told you, I'd have to kill you
it'd be 1 heck of a hunt.. ;)
I don't have a clue what mine has, except it takes up the whole wall
the HDFury is pretty cool (version 2 anyway), but it's $250 here
my TV is a nice Mitsubishi 3-CRT rear projector
then again, larger-screen/physically smaller units are out there now, with HDMI inputs, at 1080p
and the HDFury2 is 1/6-1/8 the cost of one of those new sets
what does the HDFury2 do?
it converts HDMI (encrypted digital) to component output, which I can then feed into my TV
but only at 1080i, not 1080p (and no 720P either)
cable to tv?
HDMI cable to HDFury2, 3-RCA cable from HDFury2 to TV
or are you talking about cable TV?
yea, I was talking about cable tv
oh, well that could work, but we just canceled it ;)
I'm on dish network I think
we get more PBS channels over the air (with an analog converter box upstairs) than we got with cable
the lowest cost digital HD cable or satellite planes here are $35-$50/month, and it's not worth it to us
we get 1 1/2 channels over the air :)
heh, that's why we had cable originally
but the digital tuner seems to pull in the channels better
and then ther eare the sub-channels ...
the CBS and NBC affiliates each have a second channel that's all-day weather (I think - haven't watched all day to be sure ;) )
one of them has a sports-oriented sub-channel
the Vermont PBS station has 5 sub-channels, and the New York one has two or three
so we get a fair amount over the air now
I usually watch recorded shows on the DVR
it's funny - I don't have a DVR
we only have one local channel
you'd expect me to have been an early adopter there ;)
the best part is fast forward through the barrage of commercials...
that's why we stick with PBS or DVDs
at least you have time to go to the bathroom with the PBS station breaks
time to chill out
you said "toast" way earlier.
heh. almost rhymes with "test" :)
I was wondering if you'd notice it
SWPadnos: want a 8 port HUB
oh, hub. hmmm
SWPadnos: yeah, a bit of a rarity these days
I think I have a dual-speed switch that acts like a hub for same-speed devices
(ie, it's like a 100Bt hub and a 10Bt hub, connected toghet with a 2-port switch)
SWPadnos: hub, RT control over ethernet, hint hint nudge nudge
yeah, I get it ;)
SWPadnos: Well I be too stupid to be able to, but if I can nudge ya in the direct direction..... ;)
I think the one I have will work though, as long as all the devices are the same speed
SWPadnos: it's free if you want it
I'm hard to nudge - I've got a very active lazy gene
SWPadnos: Well it was the only thing that I think would have put a dmaperner in just prototyping
oh, I have crossover cables as well :)
which are fine for single-unit testing
SWPadnos: Sure, but not for multiple axises
only if each axis has a separate ethernet-connected driver
for an outboard pulse/PWM generator, it wouldn't be needed
why not? KISS
that's not simple
one port per axis per port?
it is for the axis doohixkey, but not for the PC driver
token ring baby!!!
that's like ethercat ;)
you cna shove it in your luggage the next time your here
SWPadnos: you have any dealings with intel RAID cards?
no, but I had an Intel SCSI RAID cage
probably still have it actually
and what? I didn't have any Intel RAID controllers ...
looks fine to me
I'm confused... it says 8 drives, but 16 supported???
it does say 16 drives with "expander-based backplanes"
ah, ok. but at least 8 native?
looks like it - those look like the 4-drive connectors I've seen
I'm not familure enough with all the sata variant connectors. Just used to individual
this is off-topic, but with the February analog TV deadline approaching, is anyone using MythTV (Mythbuntu?) and in particular the HD-5500 HDTV card from http://www.pchdtv.com/

BigJohnT: why did you look at the pin conf. on me stepconf ? i didn't show you what i had.
I don't understand your question
when you told me it only moved one step that is common symptom for crossed step and direction
BigJohnT: you showed me the that my pin step and direction were opposite
BigJohnT: cool. thanks again
I've actually added that to the troubleshooting section of the manual
BigJohnT: where can i get the new manual ?

never every buy cheap toolholders.
toastatwork: I've learned something new today
toastatwork: never to bu el-cheapo toolholders again.
also, for slides... round bars, or L profiles? :p
err tool holders for the mill
they got 0.02mm tir -_- right below the spindle
and ~0.10 1dm down
my _better_ brand toolholder has 0.01mm 1dm from the spindle
that's 0.005 in one direction of throw

now it must surf failblog for another 2h :/

is emc-environment a executiable file?
kaien: it is a file that should be sourced into the shell. that is what the "." shell command does.
jepler: thanks, i got it
sleeping time, good night
is there a place like imagebin or pastebin to put a zip file of a config online?
how bug is it?
it would be the files in a typ EMC config
[14:51:10] <SWPadnos> http://filebin.ca/
or you can upload to the linuxcnc wiki
SWPadnos: hub or no hub?
did you say it's a 10/100 hub?
SWPadnos: yep, 8p
ok, because that's impossible :)
sigh, hang on....
it's got to be similar to mine (internal switch), or it has to choose one mode at a time
(if you think about it, you can't connect a 100bT card to a 10bT card via a hub - they won't work)
SWPadnos: DS524 24-port 10/100 (bridging between 10 and 100 Mbps filters packets!)
right, it's two hubs internally, and a 2-port switch
for the most part
I have one like that also, called a "dual-speed hub"
[14:58:53] <alex_joni> http://kbserver.netgear.com/products/DS524.asp
see - they even call it a dual-speed hub :)

who uses hubs these days...
and ethercat users probably
no, ethercat uses a ring connection scheme, and each device has an in port and an out port (IIRC)
SWPadnos: Keep or trash?
well, you can keep it. I'm pretty sure it does exactly what my TrendNet 10/100 8-port dual-speed hub does :)
thanks anyway though
SWPadnos: trash it goes... done
if only cleaning my office were that easy
oh but it is.... dumpster and a bobcat
well, I could just use a snow shovel, but there might be Good Stuff(TM) in there
if it doesn't fit in your hand, trash it
does that trump Might Be Useful

Good Stuff(TM) doesn't need to be useful
uselful doesnt need to be good :)
junk saving, I haz it

never get rid......
thats for the next generation
archivist: move sometime and you'll think differently
Ola ... I am doing a 'new install' and having trouble with the display of Axis and getting 'hashing' on the screen. ... I sent in a bugtrap to Ubuntu, and they said it is a EMC kernel issue. (8.04, using emc-install.sh to get EMC). ... Suggestions?
would need a lorry or three
servant74: they are probably wrong. did you turn off all desktop effects?
I keep to much GoodStuff(TM) so my wife says :)
Nothing special on. ... like what, and I'll give it a shot!
servant74: desktop effects break ALL opengl applications that don't run full screen (like screen savers)
Screen savers are off, nothing else with a display running, but let me go check. ... will be back in a couple mins.
I meant to say that screen savers are the only opengl apps that would work right, if you have desktop effects on.
what video chipset? did you install any special drivers for your video (either ubuntu "restricted drivers" or drivers downloaded from a vendor)?
[15:11:45] <cradek> https://wiki.ubuntu.com/DesktopTeam/Specs/HardyDesktopEffects#Outstanding%20Issues
Cradek ... I made sure that no other applications were runing, screen saver is disabled, but it still displays 'hash' on the lower 2/3 of the display when I start Axis (it goes through the splash display, and select config before the Axis screen shows and the 'hash' starts.
but those are not what I told you to check - in preferences there are "desktop effects" - I suspect you need to turn them off
[15:17:47] <cradek> http://www.neohide.com/ubuntu-desktop-effects-for-hardy-heron
this page "sort of" tells where to find them
Ok, I'll be back again:)
preferences / appearance / visual effects
sorry, I used the wrong word
no prob ... thnks for the help!
also like jepler asked, what video chipset is it and did you install a special driver? it'd be nice to know which ones are problematic.
already set to 'none'
I'm expecting it's intel
yes, i810 , built into an iPaq desktop with Legacy ports ... worked ok under 6.06 :(
I can run the LiveCD with no problem... I am guessing a conflict between updated OpenGL and the kernel, but that is just a guess with no basis other than gut feeling
[15:22:22] <cradek> https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/110299
oh when booting from the CD it works right?
now wait a second
is your CD the one with EMC on it, or the stock ubuntu hardy?
yea, that is what is making me balder. I have done both.
cradek: servant74 said he used emc-install.sh
I know, but then how can it [AXIS] work when booted from CD? That makes no sense.
this build is stock UBUNTU cd then install using emc-install.sh ... not from the live CD
If I boot from the liveCD INSTEAD of my disk, it appears to work
so you also have the linuxcnc hardy CD with EMC on it?
Now I am questining myself, but I think so.
both CDs are "live" so I could not tell which one you mean
could you try those tests again to be sure?
... to semi-start over. ... where I am seeing the issue, is a fresh ubuntu install from the ubuntu (not EMC) cd yesterday. then
put on all the latest ubuntu patches, then download and run emc2-install.sh
does that make sense?
yes I follow so far
but did you say it [AXIS, EMC] works when booted from CD [the linuxcnc CD I assume]?
yes, from the linuxcnc live CD.
that's a very interesting twist then
are you sure your linuxcnc cd is also hardy?
something doesn't make sense...
let me find the CD and boot it again.
that is one I did some time ago, so it may be buried
anyone have a link to a good picture that shows how the cartesian coordinates for the X and Z axis of a lathe are? bbl
sorry, no picture, but it's easy to explain in words
cradek: Ok, I was WORNG again! it does do the same thing under the 8.04 EMC live CD, but not under the 6.06 (all on the same hardware)
ok, then at least we have a pattern that makes sense
this is an interesting comment from the bug link I pasted earlier: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/110299/comments/30
that might be something to try.
or, try the vesa driver which will almost certainly work
a chorus of hummmmmmmms breaks out in sympathy
it seems like I'll have to buy a seco toolholder to get a good one -_-
standard for tooling is 0.015 runout
I'm going to broach some stuff
and with a 50mm broach and 200mm overhang
and china toolholders..
if my broach is 50mm with tolerance the tolerance H7
and my toolholder throws 0.015 that's twice the tolerance specified..
anonimasu: i'm sure it will align itself :o)
when you say broach I assume "tool" is a polished pin being forced through, spinning or not
then machine sping comes into action
why don't you try it out on scrape material ?
anonimasu: are u swedish?
did you8 mean a reaming tool?
OoBIGeye: align itself -_- and mess up the tolerance
OoBIGeye: yes I'm swedish
clockmakers call reamers broaches I dont , as its a different cut
hehe, spinning stuff that makes holes ;)
tomorrows project is to get the toolpost grinder operational.
I use a press with a broach
oh, yeah that's also broaching :)
has anyone used a drill doctor DD750X?
and there is a cutting broach and a non cutting polish
I need to leave for a bit
there are lots of reviews on the web, but they vary, and I don't trust them
OoBIGeye: sorry, I'd love to chat a bit I'll drop you a msg if you are here when I get back :)
cradek, look cheap and nasty, not tried
those home grinding stuff are no good as far as i know...
it's really cheap to get some one with real equipment to fix tools
cradek: dad has a drill dr. I don't know which model though. I could ask him.
skunkworks_: this one says it can make split points. I'm wary.

then you can deal with all your old milling cutters too
methinks gear forms become easy then
