If anyone cares... I found a dos boot disck to access an external USB hdd.

* Phydbleep is not a bot...
Bots dont have asses to work off..
Bots dont have $200 electric bills to pay. :)
Bots dont go postal because they've just spent 2 weeks trying to clean with a 4 year old 'helping'... :)
what do you think DUCT TAPE is for silly!
Hey, you play, you pay!
And then you pray...
hi paul_c , optocouplers on input pin 13-13-15 should be wired the same of other pins (2-8) ?
or reversed ?
ill be back
I've been busy in the shop lately
I'm cleaning up the machine.
tearing it all down and giving it a good cleaning
got any piccies on the web yet ?
I will set some up soon
the rotary table is heavy. 250 lbs I would guess
need to make proper stand for it
CNC table ?
big SEM servo powering it
C axis ?
bit daft on a CNC mill....
coordinated motion. not simple M codes
I'm sorry, they call it "w" I should have said "A", not C
parallel to Y
Ah.. That makes more sense.
I'm concentrating on lube lines and meters at the moment
I want to make sure they are all in proper working order
I just ordered replacements for the meters
So, you have the Interact II with QC 30 tooling?
do you have EMC running it?
not yet - The TNC is still fully functional
and I need digital encoders (linear or rotary) before I can EMC it.
I looked inside the cabinet and found that Centroid uses some goofy optical interface between the computer and the servo amps
Ray suggested that I talk to Roland F. to see if he could fill me in on it
It's a working control, but I want to plan for an EMC retro
* paul_c knows nothing about Centriod controls.
what are the specs on the servo motors ?
let's see if I can remember. 40 ft/lbs. 130V. 30A
something like that
they are 8" long from flange to beginning of encoder...
Sounds like the same type I have on mine...
It was originally retrofitted by a company called Hurco
their control must have died and then someone replaced it with the Centroid
It has a very unique Z axis system.
the quill is pushed up and down from a rod connected to the spindle through the head
I'll have to post pics somewhere
time to go do more cleaning. talk to you later
paul_c: you around ?
what if optocouplers on parport are slow ? will i get some msg like 'following error' or not ?
nope. You'll probably "magically lose steps"
EMC doens't support a PC Joystick does it?
Not that I know of - But it is a trivial enough application that you should be able to code one up.
Since when does linux support BASIC?!
been around for years..
really? I'll be damned
[17:17:15] <paul_c> http://packages.debian.org/cgi-bin/search_packages.pl?keywords=basic&searchon=names&subword=1&version=stable&release=all
why want a joystick ? to manually move axes ?
Jacky^: No, to turn emc into a PONG game =)
if so, why not connect a joystick directly to the controllers ?
* Jacky^ can't understand ..
Jacky^: connect a joystick to emc (which is a controller)?
Jymmm: sorry, i've not understood what you are doing and why..
Jacky^: To build a dedicate console using standard components as much as possible. PC joystick, I/O using PS/2 keyboard, etc.
Jymmm: nice work
Jacky^: something like this http://search.ebay.com/5798877322
Jymmm: cool, touchscreen lcd :)
when i'll find more time i want to check about handheld apps ..
i'm 75% sure it could be work with emc
in some way
of course, it's touchscreen too ;)
I like the idea of a touch screen (over buttons) becasue it's a natural human interface and you are not locked into a specific layout
I mean it sure dows look like TkEMC was designed for a touchscreen
good, i never eard before
add a couple buttons and a joystick and you are good to go
i could also required to write a driver, i suppose..
most act like a mouse
just no right-click
tap the screen twice for the right click
also double tap cuold work, i think ..
i like the idea of handheld, a tiny ipaq running emc :P
ram and cpu are fast now
oh this is interesting... I'm turn one axis by hand, the xylotex board is completely powered off, but out of the corner of my eye I see the on board LED light up as I turn the motor - oh joy.
steppers are generators in reverse
That I understand, but I never expected the BEMF to feed pack inot th elogic circuitry
I need to find a nice breakout board, then I can get some geckos
I like Jon's with the SSR's on them, but it's not universal
and requires drivers
Jymmm: it's a step generator..
Jymmm: that happens with servos/geckos also :
you turn them fast by hand and you feel them jump a step forward..
anonimasu : Yes, I know. But it doubles as a breakout baord as well.
anonimasu and how is you USC these days?
about as before
I got home from work about a hour ago..
went there when I woke up this morning
I think I am going to head to a lan party and meet some people..
cant sit home and rest all my sparetime
Jymmm: I think mariss ignored your mail..
anonimasu I think so too.
* anonimasu sighs
well, I'll ship the drive there.
and I'll buy galil servoamps for my next machine.
* paul_c has some Copley 423 & 422 amps to use...
I am not buying another gecko.
I'll ship the gecko there, as requested, there's nothing about it.
I'll mail him and ask him about the mail you sent Jymmm
paul_c: nice :)
hm, yeah I'll mail him and ask..
a question , will emc drive a stepperworld.com's fet3 stepper controler ?
dunno... Let's have a look...
Looks like a unipolar design
uses the parallel port 3lines for each stepper , direction, step and enable
EMC would need to be modified to do that.... and I think you would be disappointed with the performance..
what sort of state is emc in , still development or usable
Sherline ship EMC with their CNC package.
[20:29:42] <paul_c> http://www.xylotex.com/#3axis
< A better buy for just another $10
i got the controler and my cnc is a couple of months of compleation
i have been trying it with kcam , but stupid program dosent seem to work with xp on the laptop, someting to do with device drivers on xp , not that i like xp anyway
can't find any pinouts for the stepperworld stuff...
can get them 1 min
on there page under software at the botom of the page theres a image showing the port pins for use with kcam
[20:39:49] <paul_c> http://emc.sourceforge.net/Handbook/node22.html
- Pinouts for EMC
looks like kcam use epp mode...
* paul_c looks at the "supported" G codes from kcam.....
very limited subset...
could you recomend some more sutable software
windows or linux
For linux, you only really have two choices, one from Corbin (if he is still around) or emc
if you don't mind the development code, emc2 would probably work...
'fer M$, you are restricted to closed source applications that rely on the OS being free from bugs.
stepster is the only free one for doze that I know of...
dont mind betat testing it
your best bet then is to join tomorrow and bug the hell out of JMK
JMK will be easy to spot if he's around tomorrow.
just look for the short(ish) load yank with a long beard.
* AchiestDragon adds chan to auto join
just trying to build emc2 from cvs and getting errors
what OS ?
checking for RT dir... configure: error: RT not found, try to specify one by --with-rtai=<path>, --with-rtlinux=<path>, --with-rtlinuxpro=<path>
OK... You don't have a realtime kernel insalled, do you ?

You will need to patch & compile an RT kernel first....
alternatively, download & install BDI-4.20 on a spare box.
what ever you do, don't use a scsi HD
quad xeon is probably overkill for emc
just a bit
jepler_ is now known as jepler
well its the only linux box i have set up her at the moment
amd athlon with 10Gb hd and 768mb ram ok ?
loads of power... What graphics card ?
Hi - I'm trying to get EMC set up with a Xylotex control box. I found instructions for changing the source code here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?XylotexBoard
However, the emcmot.c file listed doesn't have a define for XYLOTEX. Any clues on how to make emc compatible with a Xylotex drive box without building a special connector?
You need the current CVS sources.. http://sourceforge.net/cvs/?group_id=6744
that card should be OK
as long as it isn't i810/15/45
thinking about it , going to use a p4 1.4g one with 64mb ram as the athlon crashes about once a day
You'll need a bit more memory than that to run the BDI installer.... 128Meg, min.
* Jymmm lol @ SCSI
Is there a trick to logging into the CVS server? cvs -d:pserver:firstname.lastname@example.org:/cvsroot/emc login and then pressing enter for a password terminates cvs and doesn't log me in. I don't get an error. I'm running Windows and have tried Cygwin and wincvs.
pressing return should return you to the command prompt.
cvs -d:pserver:email@example.com:/cvsroot/emc co emc
is the next step.
word of warning... M$ has a nasty habit of trashing/adding crap to Unix source files.
Thanks. I've installed the latest BDI and am planning on compiling this there. Will I need additional libraries or should it just be a recompile after I make the small change to emcmot.c?
which BDI ??
Uh boy... when I get done importing this video, it'll be 18GB
BDI-EMC v4.18 [2.28.05] [682MB] - BDI-EMC v4.18 - Debian based
latest released version is BDI-4.20....
EMC won't compile on that, you need emc2
my bad.... 180GB
Jymmm: Get yourself a terravault
paul_c: Nah.... From the DV camera via firewire to the laptop, then usb to the 300GB ext hdd =)
[21:59:29] <paul_c> http://www.uniquedigital.com/unistar/teravault.htm
.loadsa space ;)
paul_c 300GB hdd $120 + Ext USB case $40 = $160 is a whole lot cheaper than than thing =)
[22:00:56] <paul_c> http://www.dnuk.com/homepage.php
< If you want bigger NAS
paul_c: is it SCSI? LOL
I have so much scsi stuff around here it's sad... all unused too!
just collecting dust.
paul_c: any recommendations for a breakout board?
the PMDX ones are fairly solid looking...
paul_c: what are you using?
and don't say 25pair cable either!
Weidmuller, Vital, & Vigilant boards.
well that's no help, unless you have spare you dont want anymore =)
now where did I put that hallibut
2 diode led burned :\
i've 12 V 1 ampere,
and i want to light on a led
about 2.1 volts (avg)
12-1,4, : 0.02 = 530
if is right..
i used 470 ohm resistor..
too small =)
On 12V ?
Jacky^ do the math
(12 - 1.4)/0.01 = R
1k should be ok ?
fer starters, close enough.
ok, thanks :)
[22:21:53] <Jymmm> http://linear1.org/ckts/led.php
You do need to check the specs on the optocouplers though..
oh, I though he was using good old red LED's
i'm adding a power led on PS now ..
Jacky^ try this --> http://linear1.org/ckts/led.php
These dumbasses... The y axis belt is starting to frey. the pulley is only on the motor shaft by 1/4". THEN I find that the motor mounting plate is not sqaure to the ballscrew due to the mount block isn't even sqaure! argh!
it's a solid chuck of metal... how in the hell do you screw something up like that?!
give it to a redneck
and they dont even have a mill in the shop, just the cnc center.
and I can't even shim it up either. has to be surfaced
Then, they switched out the 3/8" mounting plate to a 1/4" plate and mounted the linear rails to that and didn't even say a word about it.
I fear that the 1/4" plate will bow/flex over time. Is my fear justified?
any fellow x86 users here?
somebody that know how reliable the timer functions are...
i guess there must be some limit of what one can do with a x86
the TSC gives you a pretty fine degree of resolution if you just need a timestamp
emc2 doesn't want to configure under my current BDI. Is there a BDI that it will configure and compile under?
Did you read http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?BDI-4_Compile_EMC2
[22:51:25] <paul_c> http://www.linuxcnc.org/compile_farm/
says emc2 should compile....
No, I was reading http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?HowToTryEMC2
[22:52:26] <paul_c> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2
would have given you the extra link.
bah.... nfc what RS-485 is
paul_c: whats a TSC?
ValarQ: Time Stamp Counter - It's an x86 thing
Hi, can EMC run 3 axes with one G-Code and another 2 axes with another G-Code at the same time?
Does EMC have scripting language?
i have another small problem, i'd like to control a PWM servo, could i use some of the code easily to do that?
xet7: Not without doing a lot of modification to the core code.
ValarQ: Radio control servo ?
paul_c: yes, from a RC airoplane
not for CNC I hope..?
paul_c geeese paul_c, you stooooooooooopid or what?! It's for FLY cutting =)
i just thought the hal system used by emc2 could be used for this as well
An rc servo won't have the response times or power...
can two copies of EMC run at the same time and send socket messages to each other? Using different Parallel or other ports?
ValarQ: You would need to write a driver for it...
xet7: You can have multiple GUIs running on the same computer, or even across a network....
But, due to the nature of the realtime code, only one instance can be run on a computer at any one time.
paul_c: is it the stepgen module i have to replace?
ValarQ: Probably - Bug JMK about it tomorrow.
paul_c: ok, thanks
* rcsu kicks off sf.net downloads, the cvs is much better
SF have some shiney new servers installed.
maybe, but the download of the source is 4 weeks old
Ah... cvs up -dPA
and the current cvs co works fine (after 1 day of hacking)
so if I understood right, EMC has radius compensation and cutter compensation? Does it work with grinding?
If you have already checked out a copy, use update to refresh.
yes, it was the first co
i know cvs :)
xet7: It might help if you described your application.
Ok. It's grinding, 3 axels move head, and table moves below it
CNC tool grinder ?
yeah, grinding machine, timantizing, making different shape of metal with different shape of grinding stones
hmm, how can i disable vti_pci ?
it causes compile errors
problem is how I move table below it, servo motors or something else? G-codes or something else that moves it isn't in sync with grinding stone G-code
rcsu: EMC1 or emc2 ?
xet7: Your application sounds very specialised.
How well is EMC code commented and documented?
um..er... precious little..
The interpreter is the most documented.
Can EMC lathe?
It can do turning, yes. But threading is not implemented yet.
rcsu: Install picutils-dev
So what about basic grinding with 3 axels, is that ok?
paul_c: thanks that error disapeared
Basic three axis coordinated motion is easy enough... EMC can go as far as six.
Can EMC show all X Y Z coordinate numbers in real time?
And distance to go?
xet7: Why don't you tru the BDI-Live cd for yourself =)
Just burning it right now :)
The display is updated every 100mSec
the data for "distance to go" is available in the realtime code....
driiink ! :PP
