what I get with ctl-c:
do an lsmod and see how many modules are loaded
Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib/python2.3/lib-tk/Tkinter.py", line 1345, in __call__
File "/usr/lib/python2.3/lib-tk/Tkinter.py", line 456, in callit
File "plat/nonrealtime/bin/axis", line 566, in update
if i != a[-1]: widgets.code_text.insert("end", " ")
Ooo, interesting - it didn't come up this time
freqmod 278624 0
rtai_shm 9088 1 freqmod
rtai_up 53308 2 freqmod,rtai_shm
rtai_hal 18252 1 rtai_up
adeos 18304 2 rtai_up,rtai_hal
Is the number of modules important?
well on my end there was about two pages of modules loaded
and i think thats what causing my problems
Same here - just the regular system stuff
cradek: is there a quick and dirty method to remove modules, other than rmmod each one ?
slomo: what are you thinking?
there are far to many modules and i get errors on boot, can't remove unused modules
slomo: I've compiled a 2.6.9 kernel on my own Debian system, and I have a bunch of modules of IDE controllers marked [permanent] from lsmod - I'm puzzled as to why, but they don't seem to hurt anything
I'm interrupting it from update(self) - so where is the window?
Is there a debug output from axis?
Hm, maybe a better question to ask, since I'm not running a default .ini - Does Axis work with bridgeportio?
Okay, that's not it
today has been a frustrating day ...
got the G2002 code from steve hardy with the emc interp embedded
tried it last night .. worked a treat
been following that on the gecko list
tried it agian today and it does fandango on core
id believe I had dreamt it, but my wife saw it too.
anyway .. what you been up to?
work, hauling junk, trying to clean out the basement, ebay, planning a bathroom remodel.....
I just can't seem to resist dumpster diving
coo. hauling junk?
hauling junk in, or out?
brought the stuff that I grabbed over the last couple weeks home over the last 3 days
Stuff = junk you keep
junk = stuff you throw away
I got's lots of both, and sometimes it's hard to tell the difference
seen the wiki develping nicely?
re: servos... 12 motors, 6 controllers of various types and stages of disrepair, and 15 or so axis modules (AB 1394 AC stuff)
plus three analog DC servoamps and motors
thats a good haul!
robin: what's the current url on the wiki? I've lost it
I'm gonna pass much of it on to Ray, he can make better use of it than I can
* asdfqwega needs to find the dumpsters jmk is diving in
asdfqwega: linked from linuxcnc.org or http://www.redpoint.org.uk/cgi-bin/emcinfo.pl?EmcKnowledgeBase
how about a couple HP Netserver LPr computers... 3-1/2" high rackmount jobbies
asdfqwega: set the admin password as 'emc' in preferences to edit it
one is dual P3-600, with 2x18G SCSI drives and hardware RAID
the other is a single P2-400, 2x9G drives
I have a new server here ..
I wish I had more bandwidth, I'd set one of these up and serve BDI images and such
1U, dual Xeon 2.8ghz em64t, 1gb ram, dual psus, dual 3gb scsi on hw raid
yeah, bandwidth ...
wow... how'd they fit all that in 1U?
dunno .. theres a cdrom and room for a floppy too
wait, 1G RAM and only 2x3G disk?
more like it
3G is just about big enough for swap ;-)
plus dual 1000BASEt network cards and 2 pci slots ...
its quite 'compact' :)
these aren't really compact
only 2U hi, but 27" deep and 40 lbs
I really need to clean out my mailbox more often
336 messages (95% emc related)
I have over 600mb of mail ... maybe more
in your inbox?
* asdfqwega drops his soda
wait .. 2.3G
I meant 336 messages in the inbox, from the last 3 weeks or so
archives of previous years I meant
wow. thats a lot
I didnt realise mec was so active :)
I have something like 67 Meg total
perhaps we can persuade the rampant emailers to write stuff on the wiki instead :)
I'm subscribed to users, developers and commit lists... it adds up
1/4 of users is "I have a problem"
hey, sign up for Ixion, the motorcyclists mailing list .. 200+ messages a dya :)
1/4 is "post your .ini"
I read em using a webmail client, but every so often I need to download them to clean things out
I've been switching computers too often to accumulate email
I do, however, have a 138MB .tar.gz of my .mozilla somewhere around here
sigh ... I wish I could get this board to work again ...
its deffo not running.
its OK with other version of the code though
yeah, the 3003
* robin_sz cant type
I'm not really set up to debug it ...
I guess I need the Dynamic C package to run the debug stuff over the serial cable
gezr, hey, missed that message you sent. good.
someday I want to get a g2002 and do a HAL driver for it
but that comes after about 200 other things on the TODO list
excellent sleep cycle. slept from 10pm-5am, and from 9am-6pm. :( I think I maybe sick,or allergies from the Toronto Smug.
jmkasunich: and first you have to get it passed by The Board ;)
yeah, right, sure, I'll make sure to do that first
* robin_sz stops stirring
* jmkasunich looks at board mailing list archives
4 messages since October
real active, this board is
I saw the feature tracker kinda stopped accumulating more features a few months ago
I wish people would use the trackers more
did any of them get done?
any what? bugs and feature requests?
6 closed since september
there are entries from as recently as december
'k some got doen then
most people aren't using the trackers, they just do what they do
if it can be made to work, the G2002 with the emc interp and a usb link to a windows front end looks like a dream ticket for me
this Fox GUI isnt bad either
seems to run on Linux and Doze
you can even compile for the doze verison undoer linux ...
saves a bit of pain
* anonimasu yawns
oh kewl ... hes doen a 3d openGL toolpath visualization tool too
hm, does anyone of you do any work on the .ini parser?
worked near it, not directly on it
what do you want to know about it?
hm, there's a problem with the .hal stuff
that's my department
what's the problem
inverting pins in the config file dosent seem to work..
I am not running the latest CVS though..
* robin_sz adds "try the latest version of emc2" to his weekend to-do list
but pin-01-invert in the .hal files dosent work..
how is it these dyas anyway? ...
how are you inverting? with the "polarity" lines in the .ini file, or using the HAL
the direction lines..
err using the hal..
let me start an emc2
I ended up hacking my parport driver to invert it for me..
"your" driver? meaning you aren't using the hal parport driver? or meaning you hacked the hal parport driver
I hacked the hal parport driver to give me my outs inverted..
but, that's a bad solution..
strange... if the "invert" parameters aren't working, then there's been a bug in that driver for a year or more, and nobody noticed...
err the problem is this line: linksp Xdir parport.0.pin-02-out-invert
ah, I see
pin-02-out-invert is not a HAL pin that you link to
it's a HAL parameter that you change from 0 to 1 to invert the pin 2 signal
you want to do:
linksp Xdir parport.0.pin-02-out
setp parport.0.pin-02-out-invert 1
to undo the inversion:
I thought it was a pin.. since that's the way it's written in the hal_intro pdf..
setp parport.0.pin-02-out-invert 0
* jmkasunich checks the doc
in the port diagrams..
page 71 I belive
maybe I didnt read enough, but it looks like a secondary pin ;)
wait a sec need to grab the file
pins are the ones that extend thru the border of the block
anything that is entirely inside the block is a parameter
4.1 and the one on top
I didnt read enough
* anonimasu feels stupid
the problem with docs written by the program author is that he already knows the info, so he can write very confusing things and not realize it
* robin_sz nods
been guilty of that many times myself
* anonimasu too
it's hard writing about stuff you've designed...
unfortunately, it's even harder to get others to write about it... so if I want it documented (and I do), I have to write it myself
yeah, the fit of activity on the wiki seems to have tailed off a bit
I see a bit on the NetMos // port card got added tonight. neat :)
* asdfqwega adds a page to the wiki
was that fun?
...I need clean pants, it was that fun.
* jmkasunich takes a look
I added that because I remember something in the EMC archives about NetMos cards
* robin_sz nods
if lots of little bits of knowledge get filtered into it .. it will be a useful resource
ok, I see something I want to change, how do I do it?
Use a hammer
put 'emc' as the admin password
press 'save' at the bottom of page ...
I set my own password as well, right?
dont bothher with that
just the admin password will do
back to your page you want to edit ...
leave it completely blank? (there was one * there when I started, I already typed a password over that)
Ugh - wiki does strange formatting changes
whatever .. balnk, *, wibble
it doesnt do what you think it does
ok, back on the page I want to change
I need to edit my own writing now
I want to add a URL (link outside the wiki)
just type the url
[01:53:38] <robin_sz> http://foo.bar.net/bar
no <a href="blah"> </a> tags needed?
should I put anything in the "summary" line?
if you wish to describe what you did ina summary, yes, but its not important
blank is fine
would it accept the HTML tags if I use them?
but not <a></a>
There, all better
I don't want the whole stinkin URL visible, just the name of the document
here] would work too
figures... they go and invent another syntax when we already have a perfectly good one
* asdfqwega scratches his head
What do I know that others need to know, but I don't know that I know?
jmkasunich: the problem with accepting html tags is it leaves it open to such things as cross-site scripting and various other attacks
whatever, just type stuff, information is more important than presentation style ..
generally speaking it just Does The Right Thing
and if it doesnt, soemone else will edit the stylee thing
* asdfqwega could murder a steak right about now
but content is crucial
well in this case, the content had been copied from linuxcnc.org, but the links were busted
it retains the [ brackets ] t denote off-site links
Later, guys - and be sure to talk about lots of interesting things while I'm gone so I can read the backlog :)
click on 'recent changes' at the top to see what people have doen
asdfqwega: cheers dude, have anice one
how do I create a new page and link to it?
first creat a link to it .. it triggers on two things:
or [[a new page name]]
just edit a page that you want the link to appear in.
go to the Xylotex page
I want to create a page about using Xylotex with EMC2
my attempt at making the link is there, with a ?
click the ?
duh, the ? is a link
* robin_sz nods
type stuff, press save
Steve Stallings is pretty up-to-speed on the formatting and keen to help out, but doesnt have huge amounts of EMC knowledge (or so he claims) .. so just tyep stuff, someone will make it look pretty :)
how do you do the equivalent of <br> or <pre> </pre>?
mostly you dont need <br>
just pressing return will do it
got a list of halcmd commands, want one per line
ahh, one moment .. thinking :)
copy/paste from the .hal file into the wiki window didn't work
* jmkasunich tries <pre>
* robin_sz goes to look
works better if I can actually type
you can see why they are popular for group documentation projects ...
manu users make light work
OK, I searched the wiki on ModUse and got so many hits on <pre> that the search was useless. What does <pre> do?
pre formatted text
its an html thing
<pre> some text </pre> means that "some text" is formatted, and the browser shouldn't screw with it
usually causes the browser to use a mono-spaced font, and respect the tabs, linefeeds, etc, in the text
[02:16:50] <jmkasunich> http://www.redpoint.org.uk/cgi-bin/emcinfo.pl?Xylotex_With_EMC2
OK, I thought the wiki editor was pretty good about that as is, but this example proves otherwise.
yeah, sometimes, its handy ...
but generally, just let the text flow and the browser sort it out
for things like ini file snippets, it
it's invaluable, IMHO
* robin_sz nods
if just a page a day gets added .. it will be quite someting fairly quickly
There is also another handy one for documenting wiki code examples. You can <nowiki> and put any HTML here and it will be ignored until </nowiki>.
I see folks have been playing a bit
I added my 2 cents there
(2 cats actually)
* jmkasunich needs a bigger KVM switch
what way gives me a better finish if I'm milling a hole?
has anybody been able to compile the simulator under linux 2.6?
morning whoever is around.
robin_sz, I haven't tinkered with the BDI much yet. Is there a visual 3d simulator on it?
dunno ... there is wossisnames Axis thing .. dunnu if its on the BDI
robin_sz, uh, is there a name you could give me so I could google it?
dang. so hungry... haven't eaten in 7hrs.
uh, no, but .. it must be on the users list, we could put it on the Wiki!
ive not managed to compileit here, so ive not seen it

hmm people coming out of the woodwork. :)

most of the text stolen straight from the Axis hoempage, obviously ;)
robin_sz, hahahaha. :) thanks.
Hi Robin, which wiki engine is used for emcwiki ??
if you want a wiki running, just say
do you have to much bandwich :-)
not loads .. couple of megs
depends on how popular the wiki is :)
i have at work also some servers running, with a nice wire to the net
3GB from the network center to the world
but only a 100MBit wire to the network center :-)
yeah, we have a rack in a london colo center
but we only pay for 2mb at the monent
a compleate rack ??
not that cheap
ok thats cheaper for me, have only to take another old computer and to find a new network cable and to call the network center to open the ports if i want to conect a new server to the net
same here, I will be removing a old 17U server and replacing with 1U next week, then I have lots of space.
we tend to use 1 or 2U machines, old boxes are big and slow
or maybe these blade servers, are also a solutian
possibly, but 1U machines are cheap and powerful
8 servers in a 4U housing, i think
just got a 1U dual xeon for 1700 gbp
I use 600MHz PIII computers (Siemens Celsius out of our old computer pool, very stable) for 0 EUR :-)
but maybe a smal rack would also be nice, but than i have to buy some new servers
not that professional to use old computers but i have enough space and it's working wery good since 4 years up to now
yeah whatever works
usemod is simple to insrtall .. 5 minutes max
and some hours more for fine tuning
and playing with it
I was searching last year for a wiki that can do good PDF exports but i give up
on a US keyboard, what to alt-# do I hit, to get a euro symbol?
sterlin/pound symbols as well.
Imperator_: if you tink about it .. its almost impossibe
Imperator_: a wiki is not structured into any order is it .. its just a web of interelated pages .. what order would they come out in a pdf?
A-L-P-H-A : altGr+E here
won't work. :/
the "alt" button on the right side of the keyboard (on a german one)
� - alt-156
robin_sz: maybe it has to take thestructure of a index page
� did that show up for anyone?
� <-- supposedly a euro sysbol, but doesn't show up on my end.
� <-- Euro Symbol
that looks like the corner of a box. The top right corner.
than you don't have it in your fonts
are you on a windoze box ?
[13:02:59] <A-L-P-H-A> http://www.winnetmag.com/Article/ArticleID/15170/15170.html
<-- this tells me it's ctrl-alt-4
but it lies.
I talked to the guy near me (buddy) that got the motenc-100 working on a real machine
do you have it in the symbol table of windows
everything seems to work
yeah, ctrl-alt-4 works in all problems, but mirc.
mirc is screwey
but I want the symbol. :)
maybe mirc uses a font without that symbol
I would like a different font with mirc
but seems to be stuck with one
but if you swich to another font the others will have still the standard font and they see nothing
* Imperator_ back in a minute
Oh I found the fonts menu in mirc
nah, you can change fonts in mirc. I figured it out.
it was the font.
yeah, double click upper left of a window
there, a euro sysbol
just that this font is ugly.
funny that it comes through even though I am using a different font here
yeah, the default font mirc uses doesn't support the euro symbol.
it comes through with arial
So the guy with the motenc machine has found a Bridgeport for me
Ballscrews, old control, no motors
sounds like an ok deal
I saved back some of the SEM servos I was selling ....I will use those
OH! I finally found a nice font.
They are oem for bridgeport anyway
Lucida Console. :)
works well for mirc.
Heh... I have a couple thousand true type fonts on this machine....I use them in the cam program for cnc v-carving
brb... reseting all windows. les: remind me about the TTF stuff
TTF fonts... got some nice ones?
I think so
I'm looking for a TTF font that is like kanji (oriental characters)
many are broken though
let me find you same.
[13:23:31] <A-L-P-H-A> http://unknowngenius.com/blog/blog_banner.png
that's the font I'm looking for.
many cam programs don't like fonts that have repeated points or a tiny crossover somewhere
I know... that's why i would use outlineart (TTF -> DXF) and tweak it in autocad.
I have to manually fix many fonts
There is some program that cleans up fonts...had a demo of it but forgot the name
I don't think I have one similar to the one you are showing
but...since you showed it you already have it!
but you need just an outline I guess
yes. but if I can get the TTF of it... :P
that wasn't my site.
[13:29:01] <A-L-P-H-A> http://www.webpagepublicity.com/free-fonts.html
<-- scanning the fonts now. :(
These are all machined from TTF:
[13:30:04] <les> http://lmwatts.com/signwp.html
[13:30:49] <A-L-P-H-A> http://lmwatts.com/signwp_files/image008.jpg
<-- how'd you get the specaling?
[13:31:22] <A-L-P-H-A> http://lmwatts.com/signwp_files/image012.gif
<-- that had to be super expensive.
image12 Is the solid mahogany...it sold for $600
coo. nice price
I despair of this rabbit processor
the speckling is hand chiseled in the background...It only takes 15 min or so and gives a nice effect
Also covers up tooling marks
so, how the fsck do I clean out this rabbit good and proper.
err thats rabbit processor
not fluffy thing in cage
the latter i already know how to clean out
(pressure washer ;)
[13:36:28] <A-L-P-H-A> http://www.1001freefonts.com/fonts/rfonts2.htm
<-- close Rave Heart
One of the most popular fonts for signs (in the logo picture) is a modified albertus from the '60s cult tv show "the prisoner"
it's called "villiage"
village I mean
v carves very nicely
grab it...it's here...
[13:41:46] <les> http://www.theprisoner.info/html/prisoner_font.html
* robin_sz adds something about the L M Watts router to the wiki
oh cool thanks
heh, I stole the text off your site :)
[13:43:29] <robin_sz> http://www.redpoint.org.uk/cgi-bin/emcinfo.pl?Les_Watts'_Router
I don't think I can do wiki stuff on a doze box...not sure
course you can s
you have a web browser?
thats all it needs and the ability to type
I'm all eyes....
hm, altgr + e = euro
see that link above
what do I do...just fill out the form?
on the swedish keyboards atleast ;)
a-l-p-h-a: I think that font is caleld hirosh
[13:46:15] <anonimasu> http://www.1001fonts.com/font_details.html?font_id=960'
[13:46:18] <anonimasu> http://www.1001fonts.com/font_details.html?font_id=960
yeah. it is.
les: you get a form?
also looking for "faux chinese" "faux japanese"
oh I see...reading "basic steps"
les: if you follow the front page, case studies, les watts router .. you should see what I did
[13:48:34] <anonimasu> http://www.paratype.ru/mstore/fonts/Faux-Japanese.htm
not free though
yeah for $24. :P
but well, I like the real japanese fonts better ^_^
* robin_sz considers actually buying the dynamic C tools
right got it
now, to find some other case studies :)
I guess my router and plasma
I had better go and eat my breakfast of grits so I will...um...grow up big and strong
back in a while
[13:58:01] <A-L-P-H-A> http://www.1001fonts.com/font_details.html?font_id=1376
I think this would make for a nice milling font.
aluminium, sprayed with a glossy black, and milled out with that font.
right, thats the router done
now the plasma
ohoo... a lot of people
I was just sitting here, editing the wiki and cursing the rabbit micro :)
What is, precisely, a rabbit micro?
the uP on the G2002 controlelr board .. like a PIC chip on steroids
When you asked about cleaning a rabbit processor, and said it wasn't the fluffy thing, I figured it was just a large-ish blender.
I'm still lamenting a CNC mill I didn't get at an auction last week.
[14:09:30] <robin_sz> http://www.rabbitsemiconductor.com/products/kits/
how's the wiki going?
well, if more people added pages, it would be even better ;) .. but yeah, its going fine :)
cradek talked about adding a security feature
one of those recognize the letters in an image
Supermax (taiwan clone), big honking servos, ancient controller (DANA), 30-taper, 32-position toolchanger.
to be able to change a page
oh, I enabled a password
set 'emc' in preferences->administrator password
i know about that
but that's not a feature for all pages
not all users would know that
it is too
yes they will if they read 'basics'
because we tell em on there
and we've not been spammed since
good for me ;)
how is it in romenia
cold I expect :)
we had -19 last night ;)
niceee... I just cleaned my display :P
shiny and new now
uff, thats realy could
not inside ;)
here it's about -10 in the night and 0 during the day at the moment
can someone check a domain for me?
yeaturday I was out with the bike, after an hour my bottle was frozen :-)
[14:19:17] <robin_sz> http://www.smallbore.info
does that work?
hmm... I will definitely need to write a php script to use the ttf font -> generate a gif based on the name, and desired sample text.
Smallbore aims to be the leading site for information relating to all branches of target shooting with smallbore rifle and pistol. Much of the information will be of use to users of air weapons too.
yeah, thats the one .. just wanted to be sure the DNS worked outside of my house :)
alpha: how does this look? http://firstname.lastname@example.org
nice clean font.
I like it.
give me a moment
I'll paste you the php
this creates an image inside emails/
and outputs the <img src=emails/...> to the place where called
yeah... I'm looking where you define the font type.
my purpose was to create a font folder gallery. :)
I didn't.. :D
define the font
but I suppose imagestring accepts different fonts...
yeah. that's cool. I can figure it out from the php.net manual.
robin_sz: one question,
why do I keep getting diff-pages?
is that default?
I dunno ..
do you keep clicking on diff?
[14:30:08] <alex_joni> http://www.redpoint.org.uk/cgi-bin/emcinfo.pl?EmcKnowledgeBase
give me an example of what you click to get a diff
I didn't click anything
I opened the above URL
is that a diff for you?
not for me
Difference (from prior major revision) (author diff)
:Case Studies - machines running EMC
that's at the top of the page
have you set Show differences on all pages in your preferences?
hmm... font gallery, with it's md5 hash dumped to a database, filtering out dupes, creating a png image of sample text for preview. :)
* alex_joni is checking
I think that would be a nice little program to write up in a bit.
it was set
that explains it
after this metal bonding agent cures. :) another 1.5 hours... :)
alpha: hope it helped
alex_joni, it will, when I need to create a png file. :)
I used the script all over the site, not to place e-mail addresses
to keep spam down
now that I think of it, the name of the png's needs to be changed too ;)
alex_joni, heard of ORC? :) hehe. but really, the bot won't get to it anyways.
what probably would be good, is an captcha to actually view the email instead.
sounds warcraft like ;)
don't think a lot of bots use OCR ;)
"you want to view this email? What's this image displaying?" before the server displays the actual email.
I don't think any.
but very few
highly doubt it... it'd easier for them to just go to the next site.
Hi Alex, A-L
unless, they are specifically targeting that one particular site. Which wouldn't be that hard then.
hi rayh, aka Mr. Spam Assassin assigned spammer. :)
I can't believe how much "list" mail I loose.
heh... bulk of your emails are tagged by spam assassin as spam.
you're on some RBL.
Yep. My ISP installed a Baracuda recently -- ate nearly everything.
rayh: how's the weather over there ?
They must have had to buy garbage bags in bulk just to haul out the junk bits.<g>
Nice this last week. Well above freezing. +10-15 some days.
we had -19 last night ;)
Snow is retreating
but nice and sunny
Ouch. That is a bit harsh.
it's ok ;)
still C... <g>
I know it keeps some of the riff-raff out.
I really will miss SuSE ;)
seems a lot of changes have happened since Novell took it over
talked to buddy on the phone and he apreciated your help
Hi Les. Is the Ice gone?
ice is gone
alex_joni: What kind of changes?
les: Must feel like spring.
this is my one day off
Hey I'm glad that buddy got his machine running.
Proves motenc can do it.
rayh: first (www.suse.com is gone)
seems there is no personal version any more
I think this is the first emc/motenc up and running?
only suse professional
and the novell line
And the documents and drivers and all are more difficult to access.
don't see any download link anymore
I miss the HW and SW databases
I found something when I was running novel 9.1 but it was not open like SuSE had been.
it won't be...
so I guess I'll go away ;)
I'll change to deb
Alpha1125 is now known as A-L-P-H-A
Deb and the little ones may be the last holdouts.
at least they released YAST under GPL
some time ago
Anyone from Canada [Toronto] that uses emc?
maybe others will integrate it into their distro
Perhaps the hardware guys that contributed to SuSE will work with Deb.
I know a couple guys out in the west of Canada that use it.
The KnowledgeBase is growing.
West of Canada? You mean Western Canada? or like the pacific?
Right. BC and Calgary if memory still serves.
rayh: growing nicely
This is one week. It should be great in a few months.
robin: is there a way to generate an automatic sitemap?
Oh. That would be nice.
has anybody used HURD?
Never hurd of it.
it's intended to be a replacement for the linux kernel
and other unix kernels
debian seems to support it
[14:58:57] <alex_joni> http://www.debian.org/ports/hurd/
robin: got the mad cows desease?
Ah. I see hurd is a GNU project. I knew that Stallings did not like Torvalds.
Not our steve.
hurd of cows?
Oops sorry Stallman.
been busy haulin' stuff the last three days
You are right. I can't make backlash fail at Sherline speeds.
got 12 motors and a bunch of other stuff
I hope not, we tested it on a Sherline
jmk: I thought about two things we need to discuss today ;)
Perhaps we should have int fest at John's place.<g>
my basement is to small
alex_joni: let me guess, beer and girls?
go ahead alex
* rayh watches for the starting topics.
hmmm.. seems I can't remember what the second one was
the first one would be classicladder
* robin_sz runs off screaming
* alex_joni grabs robin back to the torture place
what about classicladder.... we already know we want it
how to hook it in?
I agree on that
the main thing... how does it hook in
I talked to paul about it ;)
my choice would be to make a HAL wrapper for it
guess what :P
I expect Paul does not agree
I am somewhere between the two solutions
I agree classicladder gains a lot from hal-hardware support
paul's idea is to connect classicladder to EMC through NML
that way you can keep the system distributed
woops am I still here
dsl dropped out
but you lose any chance of doing realtime ladder stuff
NML is SLO
I see both an NML in/out and a shmem in/out
it's not RT
but the ladder can run at RT
a RT ladder that is forced to use non-RT paths for I/O is silly
I got a mail today from Marc Le Dourain
was wondering if he'd ever reply
he did finally
I forwarded you the mail
non-rt paths can be of value if the ladder is running on a remote PC.
to me adding the extra complication of clasic ladder to emc is questionable ... adding through the unholy mess that is NML is crazy ..
robin_sz: ladder is the most accessible way to provide configurability to folks who don't write C
classicladder is the easiest way to get ladder
I agree 110% about using NML tho
I can even write relay ladder logic...hi...
if it is an add on option, fine
I see it a bit like "mini. Use it if you like.
the way I see it, the EMC core exports HAL pins... the integrator can either connect them directly to IO drivers, or connect them to HAL pins exported by classicladder and do PLC stuff with them, then route them to the IO
as standard though, it will just be another barrier that users have to pass .. we already have far too man of those
* robin_sz ndos
IMHO we need to split users and machine integrators.
rayh: yes, but
Right now when a newbee gets motion, after a bit he wants a button.
at the machine shop level, those groups are separate
Then a switch.
at the hobbiest level, they are often the same person
Since wb9min knows ladder we can put him in charge of ladder help.
Oh that's a j sorry.
I agree on ladder using hal for pins
wish paul was in here to sustain his point
so if I wanted, say, an output that stayed on for 20 seconds after the last axis stopped moving ..
I could just pick it up as axis movement and trigger a timer in ladder
ok, I sort of get it.
so say a toolchanger
that could be implemeted in ladder
and it tells emc tool loaded
or tool 5 loaded
ok, that sounds sane enough
classicladder needs to see hal pins
I'm with John that there needs to be a HAL connection for a single PC version.
but it needs to define some of its own.. right?
Looking at the tool change thing though...
we can have cl connect to hal even on a second PC
you know... windows runs pretty fast, for being an installation that's only 10hrs old.
there are NML commands generated that could spin the tool hive before the tool change command is issued.
is there a click-and-drool gui for setting up classicladder?
rayh: no there arent, if the tool hive is only connected to the ladder logic and not emc
good morning, steve.
good morning all
robin_sz: You are speaking of a multi pc solution.
rayh: even a sinlge pc solution
If it is the HAL that does the work we have to create a hal pin that responds to the pre tool command.
think he was speaking of a single PC solution
rayh: exactly - hooks into the HAL for things like pre-tool
Okay but that only works for a single PC solution.
but generic hooks
BTW, in the back of my mind I have an idea for pc-to-pc HAL connections
a HAL component that is loaded in each PC, and has the same pins in each PC... in one, they are inputs, in the other, they are outputs
rayh: the emc core and hence NML will have no clue as to how or whre the toolhive is hooked up, only classic ladder will have access to that hardware
For a multiple PC solution the IO PC would use the same HAL rt layer to pull and watch it's pins.
It is simply a second instance of the same thing.
No you don't get rt between the two.
But most of the hundred or so printed pages of a machine ladder don't require rt.
its unlikely that many do at all
you need RT if you hook your HW-limit switches through CL
Only limits, homes, probes and laser start.
IF you want to connect them through CL
HAL doesn't distingush between RT and user space pins
a user component can read a RT pin
and write results to another RT pin
but of course those results don't happen in realtime
that wasn't clear - I shouldn't have said "RT pin"
a RT module can write a pin
another RT module can read it and send it to hardware
that is a RT path
but you could also have a non-RT module read the pin and do something with it
then write it to another pin
where a RT module picks it up and writes it to hardware
that path is non-RT because there is a non-rt module involved
but HAL doesn't care
* robin_sz gets bored with his G2002
toss it over here
I don't see any problem with any of John's thinking on that level.
the question is:
what if somebody wants CL on a different PC than emc
What I think I'm asking for is another way in to classicladder.
An addition to what John is thinking.
should we provide NML paths to CL?
Yes. I would think that is essential.
CL output to hardware should be through HAL, that's decided
It might never be used in a single PC version.
and if you want you can use it only like that
set things in CL up so that it reads hal pins, and outputs hal pins
or set things up in CL to connect to a emcsvr
and get stuff through NML
response also through NML
and output through a local HAL
or even direct output to a port or comedy (that CL currently supports)
I can see the merit in most of that
And for those who do not like ladder there is grafcet
but - how do you translate NML into something classicladder can access?
classicladder deals in bits and ints, not messages
Yes we would need a translation process.
we'll figure that out later
when there's need for it
I'm satisfied with that solution to the nml issue.
we move cl into the emc2 cvs at sf?
do we have to?
surely CL is already a maintained project
all we need is a CL to EMC adaptor
but not at SF
We tried the move once and cl has moved far beyond what we have there.
it has a dev team?
it has maintainers?
and a download site?
CL is a sf project.
I wasn't aware that it is
surely an adaptor is all that is needed ... a CL/EMC interface ...
but it is...
more correct a CL/HAL interface
anyway .. Id caution AGAINST copying a release of CL into EMC, unless you want to take on the bug tracking and maint of that too
Yep. That makes a mess of things.
we have one developer who knows a lot about cl ;)
just have people install CL in the normal way, perhaps with -DHAL_INTERFACE or whatever during build time
Might be able to add one of our developers there and make the connector in their stuff.
v0.6.6 (10 November 2003) - RTAI support. Patch send by Paul Corner. Thanks to him for that nice work.
The HAL connector is going to look a lot like CL's rt stuff.
The NML connector, when it happens is going to look a lot like a comedi link.
#ifdef COMEDI_SUPPORT will be #ifdef HAL_SUPPORT
COMEDY_SUPPORT would be more appropriate
that's taken out of the source ;)
* robin_sz screams and jumps up and down on his Rabbit
sorry guys, but I'm an hour late starting on some errands... gotta go, back in a bit
no problem john
who was it on here who had developed stuff on the Rabbit?
good discussion today, wish I didn't have to leave
I think the second issue was backlash.. but I think that's pretty clear
maybe we'll continue it later
one thing that occurred to me a while ago
jmkasunich: Are you in agreement with where this c
CL discussion is?
relaxing the following error trigger in G0 moves
* rayh can't type worth a ...
robin: having two ferrors?
one for G0, one for coordinated motion?
We can build a ramp based on speed now.
But I don't think that we can put in a break point like many CNCs do.
I think possibly two following errors would be a good thing . or maybe G0_FERROR_MULTIPLIER=4
4 times the amount of ferror is possible under g0
Would it confuse folk if they ran f="the value of max velocity"
what do you mean ray?
There would be a difference if ferror between g0 and g1 f=max.
almost all CNCs have a maximum feed speed
but it might be OK since running full speed in G1 the user expects accuracy but not in G0
which is LESS than maximum traverse speed
hmm.. I just remembered smthg
too bad jmk is away
[16:09:08] <alex_joni> http://membres.lycos.fr/mavati/classicladder/io_conf_snapshot.png
what if hal-pins would be accessible through /dev/hal ?
G0_FERROR_MULTIPLIER=1 could be default.
and could be missing from the ini
Perhaps FERROR = 1.00
FERROR_BREAKPOINT = "%Max" "value"
MIN_FERROR = .01
That would create two ramps.
not up to speed here, what are you trying to accomplish? I forget what MIN_FERROR does
Sets the error point for lag at very low feedrates
i just suggested that the following error might be relaxed in G0 compared to G1 moves
since then I sort lost the plot in a fog of complication
min_ferror is the ferror for speed
Ferror and min_ferror make a plot of following error vs speed.
At max_vel the following error is FERROR.
At zero speed it is MIN+FERROR.
so it's a ramp
at zero speed MIN_FERROR
at highest speed FERROR
anywhere in between (say at 50%) it is is 50% between MIN_FERROR and FERROR
and EMC will fault if sensed error lies above the ramp value?
short visit ...
was away but read the ferror stuff
I have been setting that very tight...increase feed override 25% and it will start estopping
usually in G00
I think not caring much about ferror on G0 is the right thng to do ... so long as its simple to the integrator
most commercial machines have higher G0 than G1 speeds
It would be a good feature....but for me G0 is where I need tight ferror the most though
I like Ray's ramp approach, except I think the low end of the ramp should be defined by an independent variable, not MIN_FERROR
would be nice to have the option
it's working well too....I have had a few crashes and it estoped and saved the machine from damage
The use of tool length offsets and G10 seem to promote bad moves!
Particularly if I try to start in the middle of a program
what I did to help that was to do 9 G10 commands at each tool change
Anyway it's nice to have Ferror actually work now
Since it was fixed last fall
On servo machines actual ferror vs speed is prob a second order function
any progress on the new motion planner testing?
No unfortunately Steve.... The machine in in pretty much contiuous production till the end of this month
But looking forward to testing
must be nice to have real customers 8-)
I am getting a good eduction on how well my design holds up under that use
no big problems so far
One thing...a collet lasts only 2 weeks!
but that's hundreds of tool changes
and it's not much money so no problem
are you using the high dollar collet stuff, or normal hand held router stuff?
Just a Porter Cable 3 1/4 hp motor...and it's really not up to the task
Right now spindle HP is directly related to income
twice the kW, twice the gross
OK, I just got through reading an article about high speed collet systems. Nasty issues. Spindle diameter expands at speed, collet chatters and/or rides up into spindle.
So I am hunting for a Perske or Colombo
yes....they seem to have the first problems with the carbide shanks just gradually lapping the inside
after a certain point they just don't hold
hope that doesn't get too exciting 8-)
I need some kind of procedure to test the collet before it slips though
I does get exciting
carbide shards flying out everywhere
presumably a proper collet changer is more immune to this
yes I think so
taper and a ball-puller
the better ones are supposed to last 500 hrs or so
or so I have read
i guess yo just factor it into the running costs
I'm getting less than 100
2 dollars / hour for collets/spindle
oh yeah, it's not a cost factor at all
It's just that I don't really know when it's time to change it
change it just before it fails
I will test to see if it has some measurable parameter
you enginneer you
remember . this is production, neot research :)
bin em every 75hours
yeah 75 sounds about right
that's about twenty five cents an hour or so
use statistical methods to avoid most of the problem, if most failures happen around 100 hours, just replace them at 80 or whatever point minimizes loss from cost of new vs. cost of crash
my mate uses similar statistical methods on the dimmer production
yes I had best be conservative...cost of crash could be hundreds to thousands
But prob the lower figure....I think one could tear the motor right off without hurting the machine
we needed to figure out how much the staff needed to be suprvised .. simple statistics helped a lot .. basically, 100% of them are slackers who will stop work the moment your back is turned, thus they need to be supervised 100% of the time .. thats applied stats that is.
sell the used collets on eBay [very evil 8-) grin]
les:what collets are you using right now? stock PC?
yes the notorius pc collets
I really need a better spindle.
I wonder if you could tear apart the spindle and retrofit w/ Erickson ER collets?
yes...I think I could
they might fit
[17:01:37] <robin_sz> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=12577&item=3871719220&rd=1
buy that, job done
it would add some length....but might work fine if balanced
find a straight shank ER adapter and press it into the center of the rotor
just bore out the rotor and get rid of the old collet nose
might be hard to balance that way though
go on les, bid 5k5 ... cheap :)
that would be cheap
its worth that for the spindles
There are colombo spindles still at NEMI on ebay
but I would have to wire new electrics in the shop for that
but it would double your gross
until one reaches a termal limit and burns up the work
wonder how much a 12 hp inverter costs
or 0,7 kiloeuro?
single to 3 phase?
not sure they do 12hp single phase VFD's
I guess...no point in running the phase convrter too
you have 3 pahse?
yes...I can start about 10 hp 3 phase
so not real 3 phase then
not the good stuff from the power company
nice 30kva diesel set :)
but it's balanced nicely and makes good power
idler is a 11.5 hp motor
is it driven by an electric motor? or steam? .. some use oxen and a giant windlas dont they?
lots of run caps
yes it's oxen powered
thats fairly standard for rotary convertors
oh well perhaps if the good orders keep coming it's time to move to an industrial area
and drive 50 miles to and from work (again)
I would really REALLY hate to move that machine
les: Dave got a pretty nice commercial phase converter recently. Might ask what it cost.
I built mine
12hp is probably close to the limit i guess on single phase
soft starts a big 3 phase idler
above that, a diesel genset is a failry economical alternative
if you have space
about 100-150 amps is the limit for regular power
better that than the additional overheasds of a factory 50 miles away and travelling
naw, large converters are common, friend runs a 20 HP turret lathe on a converter all the time from 200 amp residential service
well 100 *240= about what....30 hp?
sounds about right
my converter runs about 500 w no load
I service a shop that starts 5 100hp plus converters from 800 amp 240.
but BIG VA
VA doesn't make the electric meter turn though
The idler I use is a big Baldor with 1.5 inch diam shaft
alex_joni_ is now known as alex_joni
A big couple ohm power resistor is shorted out after a certain back emf with contactors
it glows red at powerup
but is made for that
It has worked ok...once a faulty start cap blew up
it's like a bomb
anyway NEMI on ebay had plenty of 3, 5, and 7 hp Colombo spindles a few months ago
for about $800
did you buy one?
I could kick myself for not grabbing one
we did try and convince you :)
had a cash flow problem then...
but should have just borrowed from savings
I guess small business is like that
a few months of good income
a few months of zero income
sometimes you have to spend a little to bring in a lot
now you have the order, you cant afford the downtime to fit it :)
I didn't really need hp for the signs
yep in a ctch 22
but will get a break at the end of this month
then we will slowly continue to let the customer build an inventory for next year
That will prevent some of the panic when sales unexpectedly quadruple
no .. that will make it worse
well, assume they have no inventory
as sales rise, you have to match them
you get to slowly build your production
nice and smooth
now .. say they have an inventory
run out and panic again
yes, but now when they runout
sales are double what you can supply
as they have been able to make up the sshortfall from inventory for 3 months
now, if you could figure our how to keep some of the inventory
even if you just held it for them ...
you could at least track it
yeah cost of inventory is still pretty low...but rising
Good Idea...we both hold some inventory
Um what are you charging for your chartered accountancy fees these days?
this works well if the production time you use to build inventory is not taking away from other customers
Actually Dave, I looking forward to some serious DOWN time
After this schedule I am just about bouncing off the walls
to do some FUN projects?
No way can doing conversions be business justified
how about, playing some guitar, drinking fine wine, wandering in the woods and just chilling out?
So I have to condider it just playing
just beating this G2002 to death with hammers?
the rabbit powered thing?
I got the code with the EMC interp embedded
or worked fine
then stopped. its filled a byte up sor something
even re-flashing it doesnt restore it
Its a stepper controller right?
hmm uh oh
pulse gen yes
I will use stepper for the paint bot
But now I look at the numbers and wonder why I would want to paint at all
but thats whatr got you the job
Well anyway no big deal as long as it can be cheaply and quickly automated
I did decide to use that $200 superPLC I was looking at
does steppers, servos, analog, dio
has power drivers
for 200 bucks ..
programs in basic
pretty easy for user integration
wonder if I can write code without semicolons
haven't touched basic in years
right. im going off to try and sort this poxy rabbit processor out
yeah...I wrote a lot of dos stuff in it many years ago
k see you later
guess not....well, i'll break for lunch
hi les...i was off doing other things
anyone know whos 'superPLC' les was talking about?
ray off to lunch?
so how is Portland
ok. just rainy today
which is okay. we need the rain
got a skiff of snow here..but gone by now
how's EMC retro coming along?
got a phone call ...
after I get the stg card back...it had channels 2-3 dead...it won't take long to get 3 axes up with limits and homing
hmmm---the dave effect...I say hello and they go away ;-)
How much HP can your phase converter handle.
80 total 30 max start
but I have to up the fuse ratings to do that
les was talking about his homebrew being limited to 20.
20 total or 20 starting?
I don't know.
I installed a 30 start 100 total the other day.
For a little sawmill.
An I thought my 5 HP homebrew was cool :)
I did a 5 hp homebrew first but it never balanced as well as the commercial
Mine is within 5% (if I'm remembering the correct numbers), so it's not too bad.
I never was able to get that close even with 5 uf steps
I think I just lucked out - I'm only using a single 40uF or 35uF cap on each leg.
never turn down luck!
I'm going to bail...have a good one.
I am modifying classicladder right now
but it's a bit tricky ;)
the config was thought for something else,
it originally wasn't even a RT program
might be a little bit problematic to adapt it for hal
how should it connect to hal?
link to a hallib ?
which provides functions to access pins & such?
what's up robin?
sorry robin, 0.22 won't reach that far
I said "shoot", so he shot me
yes, link to hallib
then call the export_pin, etc, functions
I gave it some thoughts, and export is not really needed
cl doesn't need to export any pins
just connect to existing ones
can't do that
(like this you can use emc&hal without cl if you don't want to)
why can't you do that?
all HAL components export pins
then the user connects whichever pins he wants using signals
if you look at the Config GUI for classicladder
[19:58:48] <alex_joni> http://membres.lycos.fr/mavati/classicladder/io_conf_snapshot.png
I would imagine something like Halmeter
select for Type: HAL based pins
and then you get a dropdown with current pins inside HAL
how does that sound?
by using classicladder to connect directly to a HAL pin that belongs to emcmot, or stepgen, or whatever, you defeat the HAL pins/signals concept
I think it's only a matter of explicit vs. implicit pin export
you keep CL's pins inside (no export) - my way
if you draw a block diagram with several HAL components, each one is a distinct block, with pins at it's border, and signals connecting them
a CL block should look the same
but like this it will be difficult to define pins for CL
what type are these pins?
the way you describe it, the CL block wouldn't have anything at it's border, just lines reaching out and connecting to other stuff
doesn't CL deal exclusively in bits?
I think so
so then it's HAL pins would be bits
ok.. so I define input bits and output bits
how many do you want?
hmmm.. a bunch
about 11 ;)
kidding, let me check how many you can define in CL
CL doesn't let you use descriptive names for things does it?
they are called A00, A01, A02, etc?
they are called I0-I14
ok, the A syntax must be from something else
is the maximum really 14?
you have a page to define that
default they are at 50 both
let's see if I understand that screenshot you sent me
ok, so export hal pins based on the setting here
we won't use that one
well.. we will use it, but only partly
you'll say "1st %I mapped" (from where to count)
Type = Hal based pins
Nbr Channels = nr. of pins to export
e.g. if 1st %I mapped is 10, Type=Hal, Nbr Channels = 12
then it will export classicladder.0.pin-10-in
how does that sound?
good with me
we could imagine running 2 classicladder?
sure (I think)
* robin_sz bangs his head on the wall
what's up robin?
need to hammer a nail?
so .. I ask on the rabbit users list about my rabbit trouble ..
use a hammer ;)
and get a response ...
let me gues...
from a fscking spelling pedant
what did he say?
someting like "mayeb a new keyboard will help you write more reliable code"
or equally useful
get a new keyboard,
and slam it to his head
what exactly is going wrong? your code won't run, steve Hardy's code won't run, code won't download to flash, or what?
far far worse
steve hardys code loaded and ran just great
on saturday, it fails to boot
even when re-flashed
it = steves code?
the flash loader code works tho?
other code, even some of steves other code works
yeah, the loader works ... its a rabbit supplied cabkle and the field update ustility
maybe you changed the code?
without wanting to?
re-downloaded the zip and diffed it
do you upload a binary?
not got the compiler yet
it worked on friday (running in flash), you powered down and powered back up sat, and the code in flash wouldn't run?
then you reloaded the same code in flash and it still wouldn't run
after that you tried loading other code, and that code does run?
the other code you tried (which runs)
does it use all the same stuff the first one uses?
I'll have to dig a lot to find out
you didn't have feline static generators wandering around on your bench in the wee hours of saturday morning, did you?
unlikely .. it just sat there
the other code still runs
like Mariss' original code .. that still works
how exactly is steves code broken (IOW, what does it do now... just sits there?)
fails reste the hardware watchdog, triggers a reset
so it's not kicking the dog...
do you have the source to steve's code?
the 'dog' is an external hw one, xor of the external address lines to the reset pin on a counter
xor of addr lines?
so _any_ activity resets the counter?
lame ass watchdog
well, better than nuffin
* jmkasunich was thinking of "real" micros that fetch instructions
anyway, its hung
dead and reset
single chip thingies can be in a loop and not twiddle the address lines
jmk: they usually have internal flash
so they don't even output addresse outside
for instruction fetching
it stores various bits of stuff in internal flash
so dog knows nothing about that
so what "address bus" is the watchdog watching
robin: one question
i played a lot with testing some extreme settings
does the rabbit has some eeprom inside?
I figure something is still "in there"
alex_joni: not knowing
seen some micros who have flash/ram/eeprom
eeprom for some settings
i figure it probably does
the memory map was not helpful
maybe the code expects some settings which aren't there
or are set out of range
these extreme settings were Friday?, but it was still working when you finished?
could be a red herring
either way .. its worked
and now its borked
well there's a huge difference between "it was working when I shut it off and busted when I turned it on the next morning" and "it was working until I changed parameter X"
the first points at some kind of hardware failure
the second at config issues
well, since both events where synchronus
yeah.. but if it works with some other code
it's really weird
without a debugger I'll never know
of course I could order the Dynamic C stuff online
if I lived in the USA
I thinkl that has a debugger ... cetainly my cable has a 'debug' plug on it
so even tho you have the source, you can't modify it and recompile?
nope .. not till i get the dynamic C compiler
its cheap enough, $139
and thats with a development board I dont need and a cable I dont need either and a AC adpator I dont need
ain't marketing fun?
of course you can buy it without all that crap
for more money, right?
* jmkasunich is feeling rather cynical today
I have NO idea why they dont give the compiler away free
"hell no, I mean if we did that, people might just make their own leads and start using our products!"
marketing and business folks....
but it cost us money to write it, we can't give it away
Microchip have ot right
* alex_joni agrees
go atmel ;)
atmel, microchip ...
all the big guns ...
Off topic, but you know anybody want's an antique shortwave radio?
not microchip ;)
ooh, thats worth $$$
with the nice warm glow of valves
this one's rather dusty and paint spattered
people pay cash for Hallicrafters though
belonged to my father-in-law, I offered to ebay it for him
probably a good bet
I should probably get busy cleaning it up and taking photos
just another of the 500 things I have to do before I can get into coding again
ok ... lets revisse that, people USED to pay good money for etc
ebay prices seem low
ewwww.... less than $50
that used to be sought after gear
I did a summer intern at Northrop-DSD, used to be Hallicrafters...All the test equipment was labeled with Hallicrafters asset tags...
looks like lots of interest, just not much $$$
all the completed ones on ebay had multiple bids
There are allot of antique radio guys...Allot of the reason people get into it is the sweat equity potential....
Take a handful of really sorry parts and make something that works...
this one works, but was stored poorly... paint spatters, dirt, etc
s/works/electrocutes the guy you sold it to, gets your ass sued off/
The amateur radio market place is extremely cash poor....
for 50 bucks, Id keep it
nice thing, valves
for $50 and shipping, you can have it ;-)
the problem is probably shipping.
I don't have the space for it
Its like being in an industry in the third world, literally!
I have more than enough amateur radio gear
I'm just wanting to try this Henry PA out and see if it will go to 144mhz :)
re: electrocution... don'cha know what "AS IS" means...
* robin_sz nods
I made a 4cx1000 300 watt 144 MHz oscillator once, hi..
Really should have used a 4cx1000sk ....
I think this PA has one of those
They diffierence is the grounded screens and special socket...
the sk has the solid ring for the shield connection...
yep and the mica screen C
versus the 3 tabs....
And the socket has a fingers right over to the ring, all the way round...
ISTR running 4CX250s in SK610 and SK620s
ah, no ...
jeee... I hate this kind of code
this PA doesnt have a 4CX1000
its a 4CX1500
4cx1000 is like a 250, but the cooling fins are 4 inches in diameter...
pConf->DeviceType = DEVICE_TYPE_COMEDI+ComboVal-2
oh boy :-(
that assumes you only can have COMEDI or directportacces in the dropdown
open cover, radio has 1/8" of sawdust everywhere
wb9mjn: yeah, I know ... this PA has the 4CX1500, looks similar, but a bit bigger
wb9mjn: want the bad news?
And the connections for the grid, screens and filament and cathode are on 3 tabs stacked down the length of it...
3 tabs for each connections, that rotate into fingers on the socket...
* robin_sz nods
wb9mjn: the bad news is .. .the 4CX1500 is only the driver stage :)
Just vacuum it out....No need to worry about static with those old radios...
The 300 watt oscilator was built out of the drive stage for a 4 megawatt radar....
on 41 MHz...
this isnt quite that big
They used it for meteor trail tracking...for upper atmosphere research...no...
It was pulsed...
* robin_sz nods
vacuum and a soft paintbrush for nooks and crannies
They would overload the reciever front end everytime a plane got into one of the side-lobes...
hah, it would!
Which did not happen often, as the antenna was a phased array the size of a foot ball field...pointed straight up..
saves on masts I guess
Well...universities have limited funding...
up is a good direction
The output was 4 cavities and they were combined with branch-line hybrids made out of 12 inch air-line...
Anyway.....that s a bit OT...
And acient history...
I did finally get all three axis on my project running with the MOTENC-100 yesterday...
The last one was the Y axis.....which is driven with a belt drive...but the encoder is directly coupled to the screw...
Have not made anything with it yet,, but as far as i can tell it s working ok....
Following error not as good as the X (which has direct coupled drive) but within +/-.0005 ...
I had to make a part that was both a pulley, and adapted the 3/8 s screw shaft to the 10 mm ID encoder...
Got some timing pulley stock from SDP/SI and turned it...came out nice...
sounds a nice mod
belt drive is often an excelletn coupling method
Also made a custom pulley for the motor, to fit the original D+M 6 drive plate exactly....
post jpegs :)
in the 'case studies' are of the Wiki :)
The X drive is doing about twice as good following error...I can see when the force on the belt reverses direction during the middle of a 1 inch move...
Puts out the .0005 error spike...
wonder what a 6H6 is?
short lil' thing, only about 1" tall
A 6H6 is a power tetrode I beieve...
Probably the audio output tube...
audio output then :)
That is an OLD radio...
WW II vintage to be using those...Is that a glass packaged, or metal packaged tue ?
all tubes are metal except for 2
thats 'vintage' then :)
all tubes made by (or at least labeled) Hallicrafters
I pitched all my metal tubes from my ARC - 5 radios i had in high school just a few years ago....sold off the ARC-5 s years and years ago...
Just after WWII they came out with the glass tubes, where the pins were integral to the glass tubes..If you take apart one of those metal tubes, you
will see wires from the glass envelope over to the plastic octal bases....
hard to come by now I expect
my father-in-law is in his early 70's, and I think he said he bought the radio when he was in college, pre-Korean war
In the 50's radios the pins went right thru the glass...
right, the "mineature" tubes
so glass with octal base is older, then metal with octal base, then the all glass ones?
In the US, I would think they are around...There were zillions of ARC-5 tx's and rx's sold off after the war...When i got my novice license in 1973, that was my first
mine was a Heathkit
then an AR88D
and a 'B40' at some point
No...glass with octal base is newer...The metal tubes have glass inside, wired to an octal base, then capped with metal...
At one point somebody developed epoxy, which allowed a phenolic octal base to be glued to the glass tube...
That was right in the late 40's ...
This radio has a 5Y3 and 6K6 that are glass with octal bases, and the rest are metal
Then after the octal base tubes came the socalled "minuature" tubes with no base at all, just pins..
right, I know those
5y3 is the rectified I think...
the classic 5 tube radio
50?? for a rectifier, all filaments in series across the 110V line, etc
5 is the filimanet voltage...In the rectifier, there was a seperate winding on the transformer for the rectifier filament, as it was a cathode-less design, and t
the filament carried HV...
That is not a "5 tube" design...
A 5 tube design has no filament windings on the transformer...
not this radio - I was referring to the mineature tube ear
The filaments were as you say all wired in series and summed to 115 v ac..
those 5 tube jobbies were strictly consumer grade, the Hallicrafters is built to a higher standard
The 5 tube design radios are actually worth something on the "Antiques Road Show" as those are the ones in the fancy phenolic cases...
Hallicrafters was "communications" grade until the early 60's when Collins came out with SSB...
That is why there are still people who will buy that radio...
* robin_sz nods
Anyway....have to do the non R/T I/O hookup to the mill next weekend...Have a board coming in that I can wire all the opto isolators through into the MOTENC-100...
So, should be able to start the spindle, and unlock the Z screw next week this time....
from the computer...
Found the best bargain in 50 pin ribbon to screw terminal boards...$55....
Everything else was more than $70...
Even for the ones that are compatible to the 24 point Opto boards (which only have 26 screw terminals)...
I got this D+M 6 off Ebay about this time last year....took that long to rebuild, and get all the other stuff....
Paid about 1000 too much, as the description of the X/Y table was false, and all the bidding went way high because of that...
It was said to be a 9 by 12 travel table...When I got it, it was a 4 by 6 travel table...and all screwed up too...
What I ended up with is a 7.5 by 5.6 travel....on linear ways, with ball screws...
The electronics were pre-power mosfet R/L drives...totally useless...
jmk: still around?
I get an error about needing to define RTAPI/ULAPI
in order to include hal.h
yep - hal uses RTAPI to manage access to shared memory
ok, so I need to define one
ULAPI is ok?
you need to include rtapi.h, and define RTAPI if it is a realtime module, or ULAPI for user space modules
for user space, link with ulapi.o as well as hal_lib.o
ok, compiling and linking fine
now I need to write some code ;)
hal_init() & such ;)
gotta go, talk to you guys later
it's got nothing to do with luck :))
good day gents...
alex_joni_ is now known as alex_joni
how is EMC on being a lathe controller?
lathe control is still beeing developed
it's not fully functional yet
not sure what works right now
is there any of it usable/testable yet in EMC?
is it going to have, diamitor programming, feed/rev, screw cutter?
I'm sorry, but I don't know
maybe somebody else can help you...
who is doing the lathe side do you know1?
I know paul_c has been working on lathe support
but he's not around right now
hes on holiday isnt he?
he usually gets around here during the week too, maybe you'll catch him
yes he is
kudos, I haven't played with EMC on the lathe, but I do use turbocnc for lathe work, and I've found it to be pretty good. And you can script it to do diameter programming [albeit it'll be weird]
feed/rev = via scripting. screw cutting = yes.
is that linux based to?
we'v looking to turn a harding NC lathe intoa CNC controlled using EMC
replace the old control on it
hardinge not harding lol
I've been using turbocnc too
is this the one you mean1? http://www.microkinetics.com/cncsoft.htm
although I cant wait to get emc running.. it seems less buggy already :)
* alex_joni is running classicladder connected to HAL
I even got a signal from spindle-on into classicladder
it started to work
alex_joni: oi! .. stop that!
Great. What is it?
classicladder connected to hal
making stuff work witbin a few hours
Oh missed that line.
That is fantastic.
it's a quick hack to make it work
you are supposed to take weeks and then abandon it half finished
maybe I will ;)
well.. it only uses ulapi so far
if it works already, thats amazing
and .. the code needs testing
who wants it?
Wish I had time to set up a 2 box.
should take about 5 mins ;)
Yes. I had to trash mine and dedicate the box to other stuff.
think I'll mail it to jmk
anybody wants a cc?
im not running an emc2 box at the moment either
how's the wappit robin?
I need Dynamic C to debug it
I'll ring the UK distributor first thing
although it's only emc1
and it won't work with classicladder ;)
oh, for doze!
wait, I'll go find a 'doze box
it's sim only ;)
but it's got emcsvr compiled
so you could run the GUI on a linux :)))
ok, enough play for me
* alex_joni is shutting down
catch you later
oh, hes gone
