man, looking at backup software documentation I get a sense for how people looking at emc2 for the first time feel.
"why won't you just tell me WHAT TO TYPE so I can back up my files / run my cnc machine"
"I don't want to read 100 pages of this dreck"
"why aren't any of your default configuration files right for my system? my system isn't at all odd!"
"what are these crazy terms you keep mentioning"
jepler: lol, what are you reading?
"my tape drive is about 10 inches across, 5 inches tall, and a foot deep"
JymmmEMC: documentation for "bacula"
jepler: The tape drive is a DLT =)
Now, 5" wide... Colorado =)
I'm pretty sure at this point that I'll just use dump and a shell script :-/
jepler: I wasn't too fond of it when I looked, take a peek at rdiff-backup. It's rsync + version control
i just setup rsnapshot -- not bad
my requirements are roughly: 1. honors ext2 nodump flag, including at highest level 2. has incremental backups 3. spans multiple tapes with one backup
#1 excludes amanda and bacula, #2 excludes most of these rsync-type systems, and #3 excludes amanda again
tapes? they went out in the 90's.... 1890's that is
whatever you say, JymmmEMC
jepler: you are wrong that #1 excludes amanda
however I think you are right that #3 excludes amanda
cradek: that's true, it only requires a recompile
I don't think it even requires that - let me see if I can find the magic
I found a shitty hack for amanda that treated the tape drive as a human-powered tape library, but it didn't quite work..
this was 3 years ago, maybe I should look again
um, my backup host is off and unplugged...
strange that nobody noticed ...
"amanda-2.4.5-span_split_V7.2_2.4.5.gz: This patch by John Stange adds the ability to span DLEs over more than one tape. "
I wonder if this is something different than what I tried
what's a DLE?
Damned Long E-archives
cradek: no idea
do you need any dc300 tapes?
that makes every backup damned long
jepler: you're right, it is a rebuild (configure option I think)
this sounds like what I recall -- it splits a dump into files of a given size, and then those files can go on multiple tapes
you still have to pretend you have a tape changer as well
and you need a lot of free space on your hard drives
that makes sense. there was a similar workaround for old ext2 file size limit, I bet that was reused
I just realized I have a fairly easy path to get ethernet from the basement to the second floor, does not require recompile
SWPadnos: Oh, hey... getting fiber installed mid jan
I saw that earlier - going from faxst to even faster
SWPadnos: Well, the 6Mbps/768Kbos didn't work out... too far from CO. HAd to downgrade
SWPadnos: AT&T put in fiber, BUT... they force you to get TV to get it (bastards), so getting it for a month, then just keeping the iNet
SWPadnos: I'm still leary of VoIP, not sure if I should keep that or not.
if you have a good battery backup, it could be OK
SWPadnos: It comes with a battery, they say it's good for 2 to 4 hours. But they can't tell me if I can add an additional battery or not.
SWPadnos: I have two cases of 12VDC@7.5Ah batteries here
SWPadnos: I still have to see if they are still good. I read yesterday storing gel-cells for a long time degrades the battery if never kept charged.
SWPadnos: did I see that you got your lathe inside?
you saw that I was going to do it today
down to ground level?
but then it got cold, dark, and windy
nope, still on the trailer
we had guests for the last few days, and they stayed for brunch
when sunset is at 4:00, that's not good for unloading :)
SWPadnos: shoulda put em to work =)
spring will be here soon...
yep. we had one already. maybe another is coming in the next couple of weeks
that would be nice.
at least I now have time to move things around in the garage a little better
I enjoyed this one. I got LOTS of outside work done.
of course, all the new years fun will be on one of the coldest days so far - something like a few dgrees above to a few below, plus wind chill
fedora has its weaknesses, but the Ubuntu installer is pathetic in comparison to the fedora installer
it's open source, they should just use the fedora installer
never heard of it
CentOS is renamed RH
Many many ppl use CentOS of their server's in the DC. http://www.centos.org/
how about desktop?
[05:08:17] <JymmmEMC> http://en.wikipedia.org/wiki/CentOS
EMC used to use the red hat distro - then red hat decided that if anyone who wanted to redistribute it had to remove all red hat branding.
I think ubuntu is a good idea, I just can't believe that a commercial company would have a worse installer than the one that comes with fedora
a person that wasn't familiar with linux windows would have given up, because they chose 640x480 resolution, and their installer puts up dialog boxes that can't be resized to that small
so you can't see the "next" buttons
Until a couple of days ago, my distro experience was limited to whatever emc was using. It is kinda ugly that the installer doesn't take screen size into account.
past my bedtime here. good night.
it's really pathetically bad programming, I could almost forgive them for not using the vesa driver at some reasonable resolution if they just checked the resolution they were running at
eric_u: What, it installed at 800x600?
if it had chosen to run at 800x600, it probably would work
what does that do?
So you choosed 640x480 and are complaining?
no, I have no choice as far as I can tell?
Sure you do, unless you opted not to set it yourself.
wasn't very obvious
if I boot into the live cd, I can't change the resolution either, 640x480 is the only choice
I have 850 gigabytes of free space, and the installer wants to put the ubuntu installation in the 100 GB windows partition
then use guided
guided wants to delete the windows installation
tell it no
no means manual install
I'm not sitting at an install window and don't have them memorized. There is the option to use both, just
do I just need one partition for the install, or do I need a boot install as well?
you need at least a / and a swap partition
you can create a /boot partition if you like. doens't have to be very big, maybe 30MB
kiss... / and swap
that seems to have worked
I always wondered why the reprap guys didn't use emc
just seemed like they had to recreate it

Downloaded the emc2 sources from CVS and tried to open the project in Anjuta IDE
and it says that "Failed to parse project (the project has opened, but there will be no project view) /home/memo/develop/emc2/src: Loop detected in dependency graph"

435GB disk space, bit of overkill for a cnc machine isn't it?

Hi, I'm tweaking the meter widget a bit by adding colored regions: http://imagebin.org/34673
But I need some help in fiuring out how to read the "region"-child in this piece of xml: http://pastebin.com/m78decad6

JanVanGilsen: I think the current setup only allows for a single level of tags
JanVanGilsen: if you use <region>(8,10,"red")</region> I think you'll get a python tuple .. not ideal for the user who is writing the xml file, but at least it'll let you move forward
* Memocjro pops out a bottle of red wine and cheers to all EMC2 users in the world

it may give only the last one, or something like that

SWPadnos: did you see the goal test?
I like the guy who's laughing about having his zune stolen a month ago
I didn't look at the screenshot, but I saw the number
This was the flakey motherboard.. seems to be running with the pci-e video card just fine.. Go figure.
the one I have set up is pretty similar
Ran all night with no issue and nice low latency
I added it to the wiki
tey're on sale again at NewEgg
* skunkworks_ could find it he supposes
[16:32:37] <SWPadnos> http://www.newegg.com/Product/Product.aspx?Item=N82E16813135227
and the sempron version: http://www.newegg.com/Product/Product.aspx?Item=N82E16813135060
whats the main diff?
hmm - no heatsink?
the second one has no memory and a sempron CPU
the first one has 512M memory and an Athlon 64
for an extra $15
MAx ram 2gb =(
yeah, you don't want one as a high end workstation
[16:35:17] <skunkworks_> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Latency-Test
bottom - I think that explains it..
am I reading that right? mobo, cpu, and memory for $75?
and they do very well with RTAI
am I blind, I don't see how much memory
skunkworks saw the screenshop
enough for EMC
jmkasunich, on the specifications tab, under memory, it says max mem 2G (DDR 333 512M include)
the onboard video also seems to work fine - but it is a poor implimentation at best. Higher res/color depths causes onscreen noise.
* jmkasunich thinks about getting out credit card - the shoptask computer gets the "realtime delay" message every once in a while
SWPadnos: duh, I stopped reading that line when I saw "max supported", thought it was just the mobo limit
so - also buy a cheap pci-e video card ;)
since the existing board is a P2 or P3, I don't think I'll have performance issues ;-)
I haven't stuck a mesa card in mine yet, have you?
the onboard video has massive display corruption at high resolution, it's not about performance
if you kick it down to 1024x768 or maybe 1280x1024, it gets bearable
how high resolution? I have a 15" LCD, 1024 x 768
that should be OK, but you'll still see issues
SWPadnos: do you still have the link explaining it?
so the trick becomes, finding a cheap vid card/driver combo that doesn't mess up the latency
it's a shared memory architecture, but it looks like they gave the CPU priority instead of the GPU (which gives you icky display but good latency)
skunkworks, no, not at the moment
^ those numbers are using a Ati radeon HD 4650 off brand. (visiontek)
oh, I thought you were using the onboad
and ATI just released a bunch of code and docs for an open source driver
yeah, I just saw that, and decided my next vid would be ATI
using onboard makes things weird. if you stick a $20-50 card in, you get better performance and latency
jmkasunich: this was onboard.. http://www.electronicsam.com/images/KandT/testing/athlon64-3200ECSGoal3.png
(note latency, not screen disturbances)
yes - screenshots look fine..
screenshots are made by the CPU reading the framebuffer
its a shame there is no AGP slot, I'd jsut reuse the matrox I have in there now
I think the issue is something like the memory controller not knowing that the data is wrong, and handing it off to the CRTC anyway
jmkasunich You don't have any MCA video cards, do you?
isn't that orange slot an AGP
SWPadnos: I had to ask, ya never know.
PCIe and PCI
that's a little better than the machine I'm using right now
looks like you could get the desoldering iron out and put an agp slot in between the pci-e and the pci slot
I think this is it... http://www.ecsusa.com/ECSWebSite/Products/ProductsDetail.aspx?DetailID=575&CategoryID=1&DetailName=Feature&MenuID=48&LanID=9
can't be, it has a pci slot where the agp slot isn't
I have a quick question, i am building a cnc router and need to know if anyone has ever used the product at stepgenie.com and how does it perform with emc2
that is a unipolar driver
most in here would recommend bipolar
bipolar chopper to be precise
oh ok so if i go with the one at http://www.xylotex.com/
i should be ok then right?
more torque and speed
unipolar will give low top speed (this is general stepper motor issues, has nothing to do with EMC)
biqut2: you don't seem to have done much homework
Xylotex or Geckodrive should give you much better performance, unless you already have unipolar motors
* JymmmEMC would highly recommend AVOIDING xylotex
you start with a machine, then you choose motors that are sized to fit the machine, then you choose drives that are sized to fit the motors
i have on the software side but when it comes to the stepper motors im kinda clueless
well, lets start at the beginning
what kind and size of machine are you trying to control?
a 30 lb engraving machine and a 2000 lb bridgeport mill can both be run by steppers ;-)
it is a gantry cnc router, cutting area of 12x12x5 inches. I have already built the machine and designed it to use nema 23 motors and it will be useing a trim router as the spindle
ok, so NEMA23 size
given the small work envelope, you don't need blazing speed
Get one of these instead of Xylotex... http://www.geckodrive.com/product.aspx?c=3&i=14469
if the machine was 8 feet wide you'd grow old waiting for it if it only had say 30 ipm rapids
biqut2: do you have motors already?
JymmmEMC: what do you have against xylotex?
no, all i need at this point is the motors and the controllers for them and i was leaning toward slower motors with more torque
jmkasunich You mean other than that rants/raves over the last two years that it HAS to be the driver that is causing all the issues that I've been having?
I don't even want to start on all the issues you've been having
I don't blame the drives for that
jmkasunich Or that I had to RMA it because it blew out one axis due to thermal issues?
jmkasunich or that it doesn't have mid-band compensation?
JymmmEMC: ok, forget I asked
biqut2: what screw pitch? do you have any pulleys between motors and screws, or is it 1 to 1?
jmkasunich Ok, last one... limit of 35V including BEMF.
My router has a working area of about 6x8x3, NEMA-17 motors (2A 4.4 ohm), xylotex driver board. I am happy with the xylotex board. http://media.unpythonic.net/axis-files/01188441458/img_7045-medium.jpg
jepler: your nema17, did you get them from xylotex by chance?
jepler: what kind of rapid speed do you get?
I bet the motors came with the machine?
looks like we scared biqut2 away :-(
jmkasunich: 72ipm on the old 20TPI triangular screws direct drive, 90ipm with the new acme 16TPI screws
no im still here
just getting ready for work
biqut2: what screw pitch? do you have any pulleys between motors and screws, or is it 1 to 1?
if you don't have time to talk, come back later when you do
yes, the motors came with the machine. the seller said that the machine was capable of 70ipm rapids
its 1 to 1 and 20 tpi
but the short answer to your original short question is, you'll probably be dissapointed with the step genie
I dunno what your budget is - the genie is cheap, but it doesn't include the power stage nor the motors
both of those are more expensive than the control electronics
really not that cheap
in fact, EMC2 can do in software what that chip does, and give you four outputs that would go direct to the FETs
you'd need two parallel ports to run 3 axes tho, since that config uses more pins per motor
ok then ill go with xylotex because $310 for the entire kit is a great deal
i do like that 4 axis gecko drive though but at $300 i can get a driv. and all three motors from .xylotex
[17:15:41] <jmkasunich> http://www.kelinginc.net/SMotorstock.html
is a pretty good source for motors
and gecko makes good drives
biqut2: Xylotex doens't have mid-band compensation
if you want to look at getting the pieces separately
biqut2: keling has 425 oz-in NEMA23 motors for $49 each, so three would be $150
.. comapred to 169oz-in in the xylotex kit
biqut2: *IF* you do get the Xlyotex driver, be sure to have LOTS of cooling.
JymmmEMC: oops, yes
still, a significant difference
well i will look at getting the geck drive and those 425 oz motors because that is exactly the power i am looking for and tho whole thing would end up costing just over $450 and I can live with that
gecko G254 http://www.geckodrive.com/product.aspx?c=3&i=14472
I'd go with the 425 oz in motors if you must, because they rated specs don't seem to exactly match it's performance.
oops, I can't type
at $61 each, that would be $183, + $150 for motors is $333
jmkasunich Plus all the wiring, connectors, etc
[17:19:52] <skunkworks_> http://www.cnczone.com/forums/showthread.php?t=70712
I don't own any geckodrives, but one trade-off with them is that they don't have selectable microstepping. That means you have to generate more step pulses in the PC, and that can become a limiting factor for your rapid speeds
jepler: Since when?
the G250/G251 are 10x only
the G210 and G212 have selections (1/2/5/10)
as is the G203v
as does the G340
as are the standard G201/202/203
Well, most are using 8x anyway, no?
right, the G203 also
no, they don't have 8x ;)
JymmmEMC: no geckos use 8x
gotta run. bbl
Yeah, I know. I mean ppl are not suing half or quarter
xylotex (and others who have 8x) are typically using chips from allegro or such, and they provide what the chip provides, which is 8x, or 1x/2x/4x/8x
10x not so bad
so if you can generate 30000 steps per second that'll get you 225 in/min rapids with 20TPI direct-drive halfstepping, but only 45 in/min rapids with 1/10 microstepping (I think)
gecko uses their own design, they go 10x, and they have optional step multipliers that give you 1x, 2x, 5x
I can drive my G203v's to the best rpm of the steppers with no problem since the paraport reset thingy is used
if he has a 12" x 12" table, dont think he's gonna need all that fast rapids
it looks like the xylotex kit is offering a no-charge upgrade to 425 oz-in
[17:23:51] <jmkasunich> http://www.xylotex.com/3AxSysKit-425.htm
that price is hard to beat if you don't have a well stocked junk box
"You will be able to get more low-speed torque using these motors compared to the 269 oz.in. motors. However, these motors have a higher inductance. This means a limited top-end speed."
the gecko version would still need a power supply, and various bits and pieces (connectors, wire, etc)
so it's yet another trade-off
always with the trade-offs
also the power supply is only 24 volts
But you can always reuse the gecko for any other project, or even make a box that you can use elsewhere, even for testing.
biqut2: read http://www.xylotex.com/425ozin.htm
gecko also have opto isolation, and VFD, no breakout board needed
the gecko kit
always trade offs =)
JymmmEMC: what gecko are you talking about? the 540?
the 4 in 1
three 250's cost $183, the $540 costs $300
well i want the flexibility so i am glad i talked to you guys, i am going to go with the G540 and buy the motors seperately
paying $117 extra for a fancy breakout board seems a bit much
jmkasunich SWPadnos and I were looking at breakout boards, we never did find one that was decent. I seriously doubt that Marriss would put crao in his
biqut2: in spite of what I just said, I think you'll be happy with the G540 - I'm just a cheapskate
jmkasunich Not really, if you want to control spindel, dust/flood, etc it's already there
Mariss makes good stuff
and stands behind it 100%
keling has lower torque (probably faster) motors too
I had a drive go bad and they repaired it and shipped it back in a couple of days
270 oz-in are $39
in fact, I wouldn't be surprised to find that the xilinx kit motors are from keling
oh, the G540 needs a separate DC power supply; it's not included like the xylotex kit
biqut2: JUST FYI... Marriss has an unwritten policy that if you blow up your drive, if you are honest and tell him that you screwed up, he will replace it at no charge one time only.
if it was your fault, and you admit it
if it was his fault (defective) he'll replace it more than once if needed
well i really like the fact that the 540 is opto isolated and the breakout board and everything is in one unit, plus i plan on running a slave on the x axis for now and upgrading to a 4 axis machine later
oh - then that seems like a perfect choice
biqut2: It also has 50V limit instead of 35V
you will need to buy/build the DC supply
thats where the well stocked junkbox comes in ;-)
the 540 is the same as 4 251's plus Optoisolated and comes with the connetors
yeah i noticed that as well. i have everything i need to build my own PSU, actually i have a benchtop power supply as well
The hardest part in building a PS is finding a xfmr - logistics, my Nemesis
then it sounds like you are good to go
yeah, you helped out alot. answered all my question about the steppers (my weak point)
biqut2: I have the 3 axis xylotex plus their 260 oz in motors, Marriss told me those motors can do 50V fwiw,
I like the Automation Direct steppers
BigJohnT: Have you seen the torque curve for them... AWESOME!
BigJohnT: link? how do they compare pricewise with keling?
yes I have... one second on the link
dial up you know...
JymmmEMC: I used them on my plasma table
BigJohnT: you have cell svc in your area?
I have cell nothing in my area... I turn it off when I leave the pavement and head into the woods
[17:37:38] <BigJohnT> http://web3.automationdirect.com/adc/Shopping/Catalog/Motion_Control/Stepper_Systems/Motors_-z-_Cables
I used the 276 oz-in on my plasma table
their 276 oz-in is competitive with keling's 269, but the 434 is 2x the price of the keling 425
guess you gotta shop carefully
yep and figure the whole package out before you buy
I thought the whole table was nema 23
BigJohnT: My bad, I thought automation direct was the one in Watsonville.
near Atlanta somewhere
BigJohnT: yeah, I found out. There is another company local and the motors I have has an almost perfect horzontal torque curve - strange but very cool
When I questioned Xylotex's 269 for a torque curve chart, I big flogged and beaten for asking for such a thing.
...and that such a thing doesn't exist.
the amusing thing is the steppers are rated standing still and not doing any work
all of them use holding torque
that means 0 rpm
Is the irc log searchable?
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-12-31.txt
that is today's log
jmkasunich I want to search over the last 18 months
there is a spreadsheet on the wiki site that has all the calculations needed to pick a power supply/motor combo
if you want to search all of history, use google, and specify the first part of the URL along with your keywords
heh - build your awesome gaming right with a "sparkle" video card ;-)
jmkasunich: gaming "rig"?
I can't type
seems like I read somewhere that the "round" steppers did not have the power or speed or something that the "square" ones do
that is a bit of a generalization, but it is mostly true
round ~= old, square ~= new ;-)
ok I knew it was something but I slept since then :)
Where can I post a PDF file?
well that almost worked :/
[17:52:33] <BigJohnT> http://filebin.ca/

I'm tellin ya.... almost flat across the board.

Oh btw, that PDF seems hard to come by, so if you want to keep a copy for your library you might consider it.
hmm, the rebate on the goal3 combo expires today
of course there will probably be a new one tomorrow
whats the return policy on it?
jmkasunich, a couple points about the G540: it has 4 drivers, it has optoisolation for the remaining few I/Os, it has a charge pump detect circuit, and it has an isolated analog output for spindle control
SWPadnos: well, the 4th driver is just a waste of money on a three axis machine (unless you anticipate a 4th axis, which I guess biqut2 does)
jmkasunich Limited 30 day return policy on both of them
JymmmEMC: why would that matter?
too bad marriss didn't hit his original price point on those drives
it also comes with the connectors to attach the steppers, and it uses a single power supply, and the case is a heatsink sufficient for full power operation at 40C ambient
jmkasunich in case it didn't work out for you or they toss up a better one tomorrow... http://www.newegg.com/HelpInfo/ReturnPolicy.aspx#2
maybe all the hobby vendors told him they would hire a hit man if he did
couldn't you just pull the driver off the motherboard for the 4th axis.. (if you wanted the outputs?)
SWPadnos or skunkworks the goal3 compo - does it come with a cpu sink? does it need one?
it has a heatsink attached
reviews say no
and with a 4th axis you hove the option of running a slave on one axis rather than ussing a belt system
jmkasunich: when I bought mine - they came with the heatsink
heatsink yes, fan no
I just got lost
I don't know if mine has a fan, but it has sufficient cooling tfor the installed CPU
could always call and ask
anyway. bbl - happy new year
I think goal3 and 540 answers just got mixed up
jmkasunich BTW, I could NOT find that model# on ESC website
ecs does oem stuff
if it runs our distro, I really don't care if it is on the website
jmkasunich BIOS update
I'm certainly not interested in downloading windows drivers for it
if it works, why upgrade?
Comments mention not being able to boot from USB without BIOS upgrade
I'll attach a cdrom drive to load the os, then boot from hard disk after that
just like I did with the much older board that is in there now
jmkasunich: this is the exact combo I bought (right from my invoice) on 9/13 http://www.newegg.com/Product/Product.aspx?Item=N82E16813135091
ok, yours specifically mentions fan, the one they are selling now doesn't
I think SWPadnos bought them more recently.. Might be worth a call as JymmmEMC says
the pics clearly do NOT show a fan, and the pics of the one you bought clearly DO show a fan
too bad an l297 costs so much
well - that sucks
I paid 79.99 with heatsink and fan.
looks like they have a sink/fan combo that should work for $8
[18:14:10] <jmkasunich> http://www.newegg.com/Product/Product.aspx?Item=N82E16835200042
so - almost the same price
jmkasunich This is the only ref for info/downloads I could find... http://www.pcchips.com.tw/PCCWebSite/Products/ProductsDetail.aspx?detailid=405&CategoryID=1&DetailName=Specification&MenuID=1&LanID=0
it looks like it's rebranded pcchips board
I saw somewhere that PCCHIPS and ECS are the same company
could be, the design of the website looks alot like ESC's.
hmm, I hope that board doesn't need a new power supply
24p + 4p
jmk - it probably does
yeah, the existing one has 20 pins
pg9 of the manual
I should just stick with my original plan - get the 5i20 in there for hardware step generation, then the RT is much less critical
It also requires the extra 4 pin plug.
it is starting to nickle and dime you to death..
and I'm gonna do the 5i20 anyway
although you can get powersupplies for about the same price as the heatsink/fan.. :)
High quality of cource.

skunkworks that's 20+4, not 24+4
it has all the plugs needed for the above motherboard..
Heh, it be really funny if my IdeaPad plus this http://www.cooldrives.com/1ppaspex34.html
could run emc
it needs the 20+4 and the 4 pin cpu power connector.
skunkworks I just saw in the manual that it said 24 not 20 pin main connector, and also has the 4pin as well.
skunkworks Now, if thats to be able to use 20+4 OR just 24 solo, I don't know.
doesn't matter. (some powersupplys don't let you disconnect the +4 - so it is strictly 24)
skunkworks The IdeaPad is the last computer I will buy that has the 2GB limitation (1.5GB in this case).
have you run the latency test on the ideapad?
jmkasunich Did you say that you might be using a P2 currently?
skunkworks No, I'm dl;ing the Live ISO as we speak
I used to think it was funny that windows had a 2gb limit
lemme go look
I know alex_jon1 had gotten a pccard printer port to work.. But I don't think it was triveal.
skunkworks on a Atom cpu?
I don't think so.
what ever flavor of laptop he had
cpu is hidden under the power supply, can't tell if it is a P2 or P3
definitely slot1 tho
skunkworks This lil thing rocks, espe only on 512M ram
Our gantry is running a pentium III at the moment - slot 1.
jmkasunich I have some Intel Server mobos P3 1GHz dual cpu
the only reason I was a bit interested in that combo was that it was cheap and had good latency
I really have no need to upgrade the computer
jmkasunich, what is your latency?
normally pretty good (I've been using the machine for a year now)
jmkasunich These support up to 8GB ram
but every once in a while I get a RT warning
I get an RT warning every time on startup
JymmmEMC: why would I want that much memory in a machine controller?
my system has a hard disk that is only a little larger than that
jmkasunich no swapping
I think the disk might be 10G
JymmmEMC: you smoking something again?
this is a machine controller - the only thing I ever run on it is emc
jmkasunich If you dont realize the benefits of more ram in a system, there' snot much I could say.
I believe it has 256M (of rambus memory ;-) and it works fine
JymmmEMC: if you don't get "if it works don't fix it", then there's not much I could say either
the world is run by lsi11 systems
besides, the default kernels only provide about 3G of usable memory, even if you have more
heh - I have 2 rambus motherboards here. And 4 sticks of 128mb of ram..
my main dev box (which runs the compile farm VMs) has 4G in it, and I decided after farting around all day to live with the kernel that only uses 3.2G
probably more than you might wish
AIC-7896 Ultra1 SCSI
oh, LSI-11 ;-)
my new computer has 8 gig, so I'm going to 64bit
eric_u: is that the max it can do?
heh - this is great.. http://www.cnczone.com/forums/showthread.php?p=545660#post545660
no, but I figured 80 bucks was nice
eric_u: whats the max out of curiosity?
we have a system at work that has 128 GB ram
at some point, it's just overkill
we also got a cheaper one with 32gb
JymmmEMC: mine will take 16gb max
skunkworks: that stinks, 15 hours down the drain
I'm sure the comment by keith orr will make everything so much better
may arm hurts when I do this... Then don't do that..
well, he said he had done it before
expect a pissed off guy named Rick to show up somewhere on the list
skunkworks_: do you troll the mach boards looking for trouble? :)
I'm surprised it doesn't happen more often, I gave up on windows for control after losing a $2500 extensometer
eric_u: I don't think I post in that forum.. :)
probably a good policy
[19:06:43] <eric_u> http://www.cnczone.com/forums/showthread.php?t=63772
"what causes the occasional runaway mill?"
reading that forum makes me think it may be a good thing that all the newbies start with Mach
I suspect that makes me a bad person
skunkworks_: that guy with the proxxon that is milling smd boards is doing some pretty impressive stuff
eric_u: the thread I posted in?
the mount he is using for the proxxon looks really nice
I will have to look.
you can only see the bottom part of it though
he has a widgetmaster machine.. I like the looks of them.
you're using a sears version of the rotozip?
sears rebarnds everything =) My sears reouter is really Bosch
someone on cnczone is using the dremel flex shaft tool, I think I might try that
eric_u: it has a bit of roundout fwiw
or at least mine does
now that sears is really kmart, I can't force myself to go in there
eric_u: come on kmart aint that bad
selling the company to a bankrupt company, what could go wrong?
eric_u: what makes you think kmart is BK?
somebody found the break in the string, and BigJohnT_ is back online
eric_u: Ah, I didn't realize that
eric_u: funny thing is they filed ch11 in 2002, and recovered from ch11 in 2003. Sound like it was a pure financial thing
bummer, I found my stash of rj45 connectors, so now I have to make an ethernet cable
skunkworks_: where do you buy your bits?
eric_u: Got Cabletester =)
JymmmEMC: it's called a computer and a switch
eric_u: I guess the answer is no =)
eric_u: is that a gigabait switch and pc with gigabit nic?
yeah, I mean, no
JymmmEMC: 100mb switch, gb nic
eric_u: Ah, so can be lazy about it =)
what would I do differently if I wasn't being lazy about it?
eric_u: make sure that all 8 were crimped properly and no breaks in the cable
doesn't seem too hard
eric_u: Well, no it's not. But you should see some of the runs that I've seen others do in the datacenter.... scarry!
I'm hoping no scars
eric_u: even BigJohnT's string was better
string just broke
you said the runs were scarry
eric_u: crimped like crap, no stress relief on the RJ45's etc
I'm surprised some even had a link light
eric_u: runs == cross connects
this isn't going well so far, my crimper doesn't strip the wire worth a pfffft
I always figured that the strange way that ethernet is wired is because some guy at DEC made a mistake and they just kept it that way rather than redo the boards
eric_u: strip the wire, or strip the outter casing?
ah, the science of network cables crimping :-) make sure you have the RIGHT connectors for your cable
JymmmEMC: outer casing of course
don't just use any connectors on any cable...
Poincare: too late for subtlety
brute force and bailing wire only
eric_u: just use a box knife
what length of cable do you need? i'll make one an you can pick it up in 2 minutes
2 minutes.... Is that guarnteed to work =)
hey, where's the latency test on livecd?
Poincare: then email it?
that will work... my failure rate is about 0.05%
eric_u: if it's short enough to fit in an attachment i can mail it, else i'll have to ftp it to you
Poincare: cool, come over here I already have the cat5 and rj45's I need 8 runs =)
you're mocking me, aren't you?
Poincare: I'll supply the beer
said in my best buzz lightyear voice
JymmmEMC: I'd rather use my cables and connectors...
JymmmEMC: where dou you live?
Poincare: SF BAy Area
SF = San Francisco?
dang, blue/white went where the orange is supposed to go
eric_u: just hope the other end is the same =)
that will never happen, curse those lazy DEC bastages
JymmmEMC: just run latency-test from terminal
skunkworks thanks, found it
max jitter 366709
I also use their 1/16" bit for clearing.
JymmmEMC: you still need the twisted pairs paired correctly.. (even if they are the same on both ends..)
(mainly you just need 1,2 and 3,6 twisted... ;)
I've always been somewhat suspicious about the actual need for the proper twistedness
skunkworks DO YOU DONT - that's only if you don't want any crosstalk ;)
maybe on this 30' cable, but on a 5' cable, it can't be that significant
eric_u: the twist IS important, even on a 5' cable
See, ppl love the gui latency-test, but it returns inconsistancy with this http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TweakingSoftwareStepGeneration
certainly if you want to use gbit
Poincare: oh come on, where's the fun in that with no crosstalk =)
Poincare: do your friends know about this obsession with ethernet cabling?
it isn't funny anymore if it's the 99th problem, caused by a wannabe installer, you have to fix :-)
eric_u: it's an obsession for 'transmission lines', and they know about it
* skunkworks_ hugs his tecktronic network analizer..
Poincare: Thus why I have a cable tester, though I wish I had a ring tester too
skunkworks will it ring the cable?
JymmmEMC: if 'SF' is San Francisco, it would set a new record, furthest i had to go for some cables was Las Vegas (comming from Belgium)
skunkworks Heh, that's the one I was just thinking about... it wouldn't ring RG58 0 nfc why though.
Poincare: I'm assuming that's UK, no bigger the weather is probably the same here as there right now.
Poincare: that's a big step down in beer quality
pitty that I don't like beer...
well, we got zillions of micro brewerys around here
and zillions of winerys too
Poincare: sacrilege :)
ok, ovl max latency is 16584nS
on what system?
not too bad
IdeaPad S10 w/ 512M
does it have a parport?
ok, crimped the second connector, now taking bets
eric_u: Nope, but it does have a expresscard 34 slot =)
eric_u: Hello, it don't even have a cd/dvd drive =)
JymmmEMC: what changed?
skunkworks using the cli test and not the gui
hmm - what happens when you run glxgears?
it is running
I haven't stopped glxgears since the last results
anyone care to suggest an AGP video card with DVI out, good latency, and open source dirvers?
cradek: didn't you discover that G400 has bad latency in 8.04 with the direct rendering driver?
cradek: did you have to turn off all opengl acceleration, or just direct rendering?
jepler: do you know the diff between the gui latency test and the cli one?
JymmmEMC: the text one is a part of rtai, the graphical one is part of emc
jepler: that is right. to fix it I changed cards around until I found one that does not do direct rendering (millenium II)
jepler: which one is more accurate? As I'm seeing big differences. Or which one should be trusted more
I could not figure out how to turn off direct rendering but nothing else.
JymmmEMC: the graphical one is running under conditions more like those when you run emc
jepler: Ok, thanks
we have sound!
heh, we have wired network!
my wife wants to go downtown to see the ice sculptures
I said, those aren't ice sculptures, those are people
eric_u: goto the freezer, break some ice cubes and tell her they're ice scultures
with artistic license
I guess it would help if I inserted the wires far enough into the connector to make contact
eric_u: If you don't do it on a daily basis, you get a lil rusty
eric_u: the offer still stands :-)
by this time you could have picked it up twice
starting to look like an attractive offer
BigJohnT_ is now known as BigJohnT
making progress, we have continuity
heh - it made it to yahoo news
[21:37:24] <skunkworks_> http://tech.yahoo.com/news/nf/20081231/tc_nf/63809
are there any good stud finders that are less prone to false readings?
I use a maganet out of a hd and look for nails..
best I have found.. (doesn't work for lath and plaster though) ;)
looks like that's what I'm goign to have to do here
even measuring 16" on center is giving wacky results.
* JymmmEMC grabs magnet and will return..
heh - if I use the printer port to count my 2540 line encoders.. The max I could safely run is 300 rpm ;)
greetings from 2009 ;)
Hey alex - happy new year
we are still 8 hours away
does anyone use linux software to rip mpeg videos into dvd format and burn..
but most STB's read SVCD format
JymmmEMC: did the maganet work?
skunkworks Yes, thank you. now if the mfg would only make the length == to std 16" on center
skunkworks I played with making a SVCD once,
skunkworks why to dvd if I may ask?
I have some videos ripped from tapes (home videos and such) that I want to burn to dvd.
the few programs that I tried (free for windows) sucked
skunkworks you said nix, does it matter?
If svcd works - I will try that.
nix == linux or unix
duh - yes - because I couldn't find any decent free software that worked in windows.. :)
irc on a 46" tv is not exactly a perfect solution
skunkworks search google for avi2dvd
skunkworks Yes, I know it's a mp4 that you said you have.
skunkworks you will probably need Handbrake too
mp4 to avi to dvd
skunkworks FYI.... transcoding is a time comsuming process, dont expect it done in 5 minutes
ah - ok.. I will take a look. one of my many projects for this weekend
yes - I know. (that is what ticked me off with some of the software I tried. - took a long time to creat junk)
skunkworks what were these videos created with?
I have some Moore high speed spindles, but so far all I've done with them is drop them on my head
