so it's your logger.
is .ro romania?
that's me ;)
I like the cleaness of the site.
your site's broken with firefox
it's not as clean as it started
[11:51:30] <A-L-P-H-A> http://dsplabs.utt.ro/~juve/projects.php
it shows, but the alignment is way messedup
gotta install firefox
[11:52:30] <alex_joni> http://www.robcon.ro/
firefox is the major browser for linux... and many people are now switching from msie. :)
this is the webpage from where I work
I use Opera
know what would be cool... just an idea.
you know how you have that outline drawing?
have a video/real life video, that the outline drawing matches those movements.
ahh.. you mean on robcon.ro ?
the main page, of robcon.ro. the welding robot
could do that...
I think that would look cool... :)
maybe one day ;)
I also planned to do a flash on my front page
you guys do plasmatorches?
we sell them
I so want a plasmacutter with THC... donno what I'd make with it... but something. :)
where are you located?
I have a friend who left for Canada
actually a few ;)
cool. Appearantly are strip clubs are full of hot Romanian ladies.
so that's where they vanished
* alex_joni was wondering
hey, you're welcome to come over and visit. :)
current project list...
- complete rotary axis bracket. Need to mill the spindle mounting position.
- purchase electronics for rotary axis' 5phase stepper
- epoxy mounting tabs onto home made electronics box.
- New z-axis with ballscrew/flying nut for mill
alex_joni, so if you guys for robots, how come you don't have a cnc mill and/or lathe?
or was it you I was talking to about that?
well.. we have robots ,)
ok.. I think I fixed that page problem
yeah llooks fixed
thx for pointing it out
was an unbalanced TD
hmm.. how can I setup firefox to use only tabbed browsing
so that it won't open a new window
get an extension called 'tabbrowser preferences' and you can select it in there easily
darn.. not really working
I installed a mousegesture extension
and that one doesn't really do tab-browsing :(
tarbrowser preferences? it should work...
sec. let me findit for you
tabbrowser pref works
but the problem is with all-in-one gestures
[12:18:38] <A-L-P-H-A> http://www.pryan.org/mozilla/site/TheOneKEA/tabprefs/
oh the I don't use mouse gestures... [never liked the idea]
I have buttons, and one hand is always on the KB.
it's so easy .. once you use them
and my mouse has 3 extra buttons.
I hated them in the game "Black and White"... I never got good at it.
maybe that's why my avatar in the game was puny.
never tried black & white
hmm... on efeature I don't like...
Firefox exits after closing the last page
seems pretty ok
hey, it's FREE!
but I still like Opera better (probably because I'm used to it)
Opera is too ... kinda
well I am running the free version (ad-support)
and the ad-thingy even produces usefull links from time to time
I use adblock, and tabbrowser preferences, and it's all that I really want. [and flash from time to time]
well opera provides that by default
but to keep it free for users they have an ad-screen
heh. I made a Autocad pline to g-code converter in php. just need to do a "list" command on the pline, and it'll do it for me... with arcs as well. :)
well.. firefoy seems the way to go
[12:41:04] <A-L-P-H-A> http://pastebin.com/239128
<-- paste that into http://mycomputer.lloydleung.com/list.php
is there a way to make firefox show you transfer speeds?
when you're downloading, it shows it.
there probably is a plugin for that too.
even for pages?
or only for downloads?
yeah, plugin for pages.
downloads there is.
hmm.... tea or coffee?
4 me ,)
coffee and toast... with peanut butter.
damn good coffee I made. :)
firefox starts to feel right ;)
heh, slashdot, is slashdoted.
but I configured it for 5 mins.
alex_joni, takes a little bit to configure to your liking.
adblock is a MUST have plugin.
that's why I like opera
viewing hotmail, looks GOOD, not adridden.
and lots of other pages.
thing is.. I use opera since around version 5
a few years ago ;)
back then it was either IE or Netscape
and I got used to it
yeah, I'm not expecting you to change, or change quickly. You're better off with opera than msie.
I don't usually touch msie
only for some ap-configuration
I use msie, when a site is retarded and doesn't work with FF
wonder if that runs on firefox
* alex_joni hasn't opened msie for a few months now
at least not for normal browsing
aprox. all pages load ok with opera
I use it for the activeX for updating windows and office.
which I really want to leave outlook.
I use autoupdate.. so I don't care ;)
no autoupdate for office.
I'm gonna check out openoffice
it's very cool (openoffice)
only a little hungry on memory

crap, can find that lisp file... to do springs and spirals
eeek.. it's been a while since I touched lisp the last time ;)
[13:40:06] <A-L-P-H-A> http://www.cadtutor.net/forum/viewtopic.php?p=1023#1023
still didn't find a way to enable download speed for pages
alpha: short question
is there an extension to configure keyboard shortcuts?
I'd like to change Ctrl-D
that I don't know.
no problem ;)
google might help
it will have something to do with the gnome configurator
you are talking about firefox, right?
doze one, yes
oh, doze. I don't know anything about that.
you probably can't change it.
I'll download the source and change it
sure, but you'll never be able to compile it
that might be true
but.. if emc compiled under doze...
I didn't know people still used doze
I think firefox will too
let me know how it goes...
when I'll get to it ;)
with a big IF in there ;)
axis is higher on the list :)
but also unlikely to be done :)
that probably will actually work
I know... I actually started that
the newer python requires Visual Studio .NET...
for the price of that you could buy linux
... and a new machine to run it
a couple of new machines
and cluster them
but there's a beta.net "free" downloadable
I hacked the python sources to build with msvc 6.0
got some include errors in <windows.h>
and I gave it up ;)
anyways... if it weren't for the current employees here at work, I would have switched all machines to linux a few years ago
anyone know of a regexp command that will find me duplicate lines?
like, if the line above is a duplicate?
regexps typically work on one line at a time without memory
if you mean you want to use grep, it's probably the wrong tool
you might want uniq -d
I'll check it out.
if you want to remove duplicate lines, you can run it through sort
yeah then you want sort|uniq
maybe you should tell us what you actually want to do
autocad list command, spits it out to a command window. but the scroll log is too short for some objects.
so, either I need to do a dump of the scroll log, or some way to figure out cut and pastes to merge the two.
I installed firefox today ;)
I've been spinning motors on my g2002 :)
alpha convinced me ;)
how's it running?
firefox .. thats good.
its running smoooooooothly
segmod is good too on steppers
but this really is smooth.
Ican see dula benefits ... segmod is going to change emc a lot. its a proper look-ahead planner.
but .. although g2002 is a bit of a approximation to proper look-ahead
hear that cradek ?
it is good I have to say
oh, I was VERY impressed by segmod.
ran some detailed profiles and it just blended them a treat
only 2d stuff mind
but ... smooth.
I think I know why the g2002 sounds smooth though ...
say we have a max freq of 20khz steps
our next freq down form that is .. 12.2khz right?
figured it out... I think.
damn... I love this
FlashGot rulez ;)
in other words, we have quite large diferences between the discrete frequncies we can emit as pulses
particulalrly at higher frequencies
I think the g2002 does well here because its max frequncies are up in the several hundred kilohertz region
so diferences are smaller between its frequncy steps
I see what you mean
on steppers thats a problem I thnk
oh so... goood..... logfileon logfileoff :)
had the same thing during a H-Bridge
horray for help files. :)
on servos, wont matter
A-L-P-H-A: my acad doesn't have that
whatever .. it is damn cool to sit in you living room, with a wireless laptop, and stepper motors spinning away upstairs while you press buttons on TkEmc :)
oh, I dropped off ;)
the wiki is looking good
the rabbit dev kit I ordered is not looking so good.
* anonimasu sighs
the kits ship currently with Dynamic C V9.1
the old version is 8.5
this one is V7.0
so .. they either upgrade it or it goes back
how are you feeling?
* robin_z makes note to continue avoiding closed-source software wherever possible
cradek, it's autocad 2005... but should be in 2000+
mine is R12
[15:05:50] <A-L-P-H-A> http://pastebin.com/239165
check this I just wrote. :) using my my "list->Gcode" php code. :)
you used php?
you parsed the output of list??
[15:07:33] <A-L-P-H-A> http://mycomputer.lloydleung.com/list.php
A-L-P-H-A: don't you know autolisp?
works with plines only..
nope. don't know lisp at all.
it would be easier to parse dxf than "list"
it would be easier to access the polyline in autolisp (in memory) than to parse a dxf
well, if you want to show me how... I'm willing to learn. :)
A-L-P-H-A: at your autocad prompt type (setq p (entget (ssname (ssget) 0)))
then pick your polyline
then how is that object accessed? like it's properties and such?
well you saved the polyline entity in the variable p
to get the first point of the polyline, use (assoc p 10)
"10" is the DXF code for the vertex
what's the "10" represent?
that finds the association starting with 10 in the list p
; error: bad argument type: listp 10
I got that error
err (assoc 10 p)
now, to move to the next point, (setq p (entget (entnext (cdr (assoc -1 p)))))
(assoc 10 p) again gives you the second vertex
how many times would I have to cycle through this?
until entget returns nil
you're going to have to learn a little lisp to do what you want... I just wanted to show you how it works in general
I need a list of commands that lisp does... [if-then-else, while, for, variable definition, function declarations) and examples for me to learn the language.
(if condition when-true when-false)
(setq var value)
(defun fn (arg1 arg2) commands)
(defun square (x) (* x x))
U remember the math part... it's lisp math (learned that, but forgot... I could do it again if need be)
it was a way HP calculators did it for a time... [the highend eng ones]
that's RPN - not quite the same
here you put the operator before the values, not after
(* 2 3) => 6
RPN: 2 3 * => 6
RPN: 2 RET 3 * => 6
(* (* 2 3) 6) = 36?
try this: in autocad type circle
for diameter specify (/ 6 (* 2 pi))
k, so I can inline calculate things. :)
useful when doing metric <-> imperial measurements.
you get a circle of circumference 6
err, for radius
whatever, you know what I mean
welcome to the real power of autocad
I do that from time to time, but I always forget how to trigger the calculations.
hey cradek couple questions about using emc
bah, why this GUI segfault and leave no useful clues in the stack frame huh?
* robin_z curses multi threaded programs
multithreaded programs are great... as long as you know the flow of the process.
otherwise, they are hell. :)
need to modify a way cover... before I use my mill again.
on a machine with no limit switches or home sw and 0.00 defined in the ini ....
why does emc continue to drive thru that position ?
does (or will) emc support 'ethernet Powerlink' (http://www.ethernet-powerlink.org/)
will: don't know, definitely not soon.
power-over-ethernet has great potential
I hope it becomes a de-facto standard
it is not about power, it is about real-time ethernet
a differrnet thing entirely then
I still hope power over ethernet becomes popular
VOIP appliances will probably drive this
Im waiting for the virii that convince humble PC's to tell the switches they are 'power enabled' and get a shot of 240V up them :)
a properly designed Ethernet interface will not care
yeah, voip is the driving force in that market I guess
it is transformer isolated
been running Asterisk here for voip
* robin_z nods
going to use it to distribute audio to web clients using a cut-down softphone
323h was the other alternative ... I forget why we cast that one asside
have you investigated inexpensive voip telephone instruments?
crap crap crap... I have a part that I can't fix down... or can't think of a safe way to do it. the part is an angle iron, and I need to machine out the shorter side. And the long side is 5", short side is 3.5", and I need a 4" shim to hold the part up... but I can't figure it out... idea?
it seems the budgetone 101 is the phone of choice
gee, things have gotten cheaper in voip!
cant you calmp the shprt side flush to a block of scrap flat down
SteveStallings: have a look at the 'firefly' softphone too
SteveStallings: works well, if you are happy with a softphoen
nope, want traditional telephone instruments
hi guys... lunch break for me
just came in the office for a sec
Ordering a spin index and an expensive diamond wheel to sharpen spiral and flat edge bits
Just reading up on how to true a resin bond diamond wheel
Would rather farm it out, but with the nearest UPS pack and ship 20 miles away...
keep in mind that truing a resin wheel consumes part of its useful life and it is best to leave it mounted on a dedicated machine
don't know much about it...but I will!
also only sharpen carbide, diamond desolves in steel 8-)
yes I read that one easy way to true a resin wheel is to just grind some soft steel for a while
I will use that diamond wheel truing thing in MSC
It's prob just a bar of 1018
oh and the alumina cleaning sticks
understand I must do that after dressing to open up the grain
oh well off to lunch...later
Spent 40 minutes positioning the part for cutting... and I haven't even begun milling it yet!!! :P
I see two of you.
yea, still having problems with disconnects
quit doesn't work?
if you're registered... you can kill the ghost with nickserve
goes dead, nothing works, eventually client declares disconnect
hmm... trying to decide on what to have for lunch.
wett indian (roti), pizza, or a burger...
Indian it is! I'll be back later.

hey, you're back
connect as root?
compiling a new kernel
and I don't really like to su
wanna know a secret?
my current kernel doesn't have iptables support :))
that's why I gotta rebuild it
umm ok hi is thing on?
awsome! BDI EMC?
So, i've 2 PCs --an AMD K6 400mhz, and a Pentium Pro 200.
And i'd like to run bdi-live[4.16]. but i got confused by the web site.
does 4.*16* [not 4.08-- "Note: Please don't use with K6 processors." ]
work on AMD K6 machine?
I am pretty sure 4.16 will.
cool. thanks hey how about SiS onboard graphics chips? they still a problem?
I don't know, but if you have problems, just disable the onboard video and plug in a card.
OMG... it's 4.16 now?
I jsut downloaded 4.14 like two days ago.
or whenever alex_joni and I were fighting for bandwidth.
okie. it's still 4.14
oops my bad: http://dsplabs.utt.ro/~juve/emc/
alpha: managed to download it?
getright is good.
btw... over the weekend I'll reinstall dsplabs.utt.ro
so I'll mirror the other cd's aswell
* alex_joni boots the new kernel
digital signal processing lab?
back in a bit (hopefully)
* alex_joni is running a shiny new kernel
today i wanted to mirror the new BDI to my side, but i got only a "forbitten" from the sherline server !!
get it from me Martin
sherline complained about little bandwidth
should work pretty ok
I try it tomorrow
yay ... my iptables is running
have to look if apche can to HTTP PUT
so you don't have any access to your server anymore, Alex, hehe
this is looking fun ... being able to compile that windows crud from Linux
ooh, new browser vulnerablity ..
firfox, netscape, konqueror ...
everyting except ie
[20:58:16] <robin_sz> http://secunia.com/multiple_browsers_idn_spoofing_test
safari ... omniweb ...
try it out on that page
doesn't work in konqueror
at least not in mine
does work in opera
not much does work in konqueror :)
I kinda like firefox
installed it today
I remember trying it out some time ago, but it's nice now
we run firefox here
thnakfully my hopeless dumb-ass bank doesnt recognise it for ebanking
actually, thats not actually a problem for me
actually .. not ?
ive only been with them a year
so ive not managed to set up ebanking yet
that takes more than a year?
thought estuff is supposed to be easy
let me give you an example
security question: what is your favourite movie?
I answer; apocolypse now
error: no spaces allowed
next question favourite musical group:
error: must have 8 to 20 chars
result, I end up entering stuff that isnt my real answers and cant remember it next time
you need to be a special kind of moron to invent a system like that
the best bit is .. to register, you have to write your password down on a piec of papaer and hand it in at the bank
now that's secure
hey an0n, feeling better?
alex_j: not really I had a couple of painkiller earlier.. so it's gone for the moment
thought we (.ro) were behind with this stuff, seems everybody is
drink'em with vodka ;)
then you'll be sure to not feel anything ;)
hmm the firefox thing is interesting
anyone knows how ip_nat_irc works?
iptables module for irc nat support
probably a module for translating dcc requests..
err the address sent with them
from the internal ip to the external.
hmm.. could be
usually you do that on the irc client instead..
doesn't seem to make any difference
still no s*dding rabbit compiler
alex_j: what are you trying to do?
either this compiler nonesense is resolved by 12pm tomorow, or the postman can tak it back
Need your thoughts when you get a moment.
I added an approach to glossary in the wiki.
are you trying to get your DCC's to work or somthing?
Not certain that it's a good one.
an0n: not really.. just wondering
rayh: opening now
seems OK to me
nice use of advanced features too :)
robin: I think of some good sauce to go with that rabbit
cook it ;)
I wonder if we would be able to search for anchors within a page.
it does anchors in some way
Saw that but my head was not able to get round it.
:D DONE! the rotary axis is completed... all that's needed now to make it work, is a 5-stepper stepper driver...
why am I a wiki page?
each author gets an auto generated one
cause you're spe-shoe.
you can protect it from people writing Bad Things with your password :)
RayH doesn't have one ;)
neither do you.. or at least it doesn't show in the list
actually I don't mind ;)
rayh: the Glossary looks good to me
alex_j: where are your page on the wiki?
[21:39:56] <alex_j> http://www.redpoint.org.uk/cgi-bin/emcinfo.pl?Alex_Joni
robin_sz: Do I need an individual editor password or is the default password enough?
default pass gives access to the entire wiki .. your pass doesnt do what you think it does ;0)
I thought the personal pass is for remembering me
You think it's time for a general advertisement of the EmcKnowledgeBase?
it's right on the front page of linuxcnc.org
pretty advertised to me ;)
but posting to the lists would be ok
Interesting. Alex_Joni gets a page but it is not connected to the main page.
what wiki entry did you put in?
why should it be?
btw, google finds the wiki
(searched for "emc wiki")
link no. 3
ive got several wikis running now
two doing well
Okay. Rayhenry has a page link but no page.
one absolutely zero interest
this one and a shooting one doing really well
bugger all interest in the G2002 one
'cause he has not clicked on it and saved anything.
did you guys try emcconf?
I tried vodka
is that similar?
I wasn't even aware it exists
I just got a load of 33d scans back
you get a working .ini afterwards
very kewl ...
wanna see some jpegs?
[22:00:58] <alex_j> http://img180.exs.cx/img180/3449/emcconfig12vy.jpg
[22:01:43] <robin_sz> http://www.quacky.co.uk/~robin/pgrip.jpeg
have them in Rhino,
[22:02:32] <alex_j> http://img176.exs.cx/img176/9408/emcconfig45ba.jpg
and I have some CAM output, 1/2" router rough pass, 12mm ball nose surfacing pass
how did you scan it?
hm, why didnt you cad it?
its comlpex shape
yeah, but still :) wouldnt it be cheaper then scanning?
not sure how I would have created it in cad from scratch
well, scanning was �600 for two
but ... we'll make 100 plus of them
wanna see what it goes on?
I'd have used splines.. to build it up..
from the bottom to top :)
[22:05:03] <robin_sz> http://www.hps-tr.com/ultraStocks.htm#fr703
alex_j: Looks like progress is being made on the configuration stuff since I saw it last.
anonimasu: yeah, I could do something that *looked* similar with splines and sectional curves
I love the ts701.
anonimasu: but actual fit is the key here, it needs to fit *just right*
robin_sz: yeah, but after making maybe 2-3 prototypes and modifying the model to fit..
I forgot Yanks are gun freaks.
or well, take lots of measurements..
oh, it's brits.
* anonimasu isnt a gun freak
* robin_sz isnt a yank either :)
but the look of it is nice.. now with a silencer ^
* A-L-P-H-A can see anonimasu playing real like FPS... and sitting in a tower camping.
these are high accuracy competition guns, typically used in major comps like commonwealth games or olympics
a-l-p-h-a: actually I do that on nthe occasions I play ;)
real life FPS?? :)
in UT2k4, it's kinda hard to snipe at times... I used to do it in other games.
hm.. I love the sniper of that game..
easy to run around zoomed in..
yeah, I bought the game, and I've played it on/off... haven't touched it in months now, since I've been motivated in getting my mill and lathe into action. [well, lathe has been up and running for 3 yrs] just got the mill functional last week.
zooming is for pansies. Real players can hit the pixel without zoom. :)
I just play it when I am around my rl friends..
especially those that play at 800x600 :) Bigger pixels to hit. :) hehe
* alex_j hasn't played in a while
but back when I was playing it was DF all over
I actually just deleted yesterday... I'd need to reinstall if I were to go play again.
I like onslaught more.
we used to play that a LOT (4-man teams)
hm, I like ctf :)
I was a sniper ;)
I miss the times when I played TF
quake + tf.. that is
no.. that's tf
tfc is a hl addon
tf is the orginal..
rayh: emcconf looks pretty ok,
Mega Team Fortress was for Q1.
it was so nice :)
doesn't handle directories though (expects standard locations)
I played TFC (half life)
it was fun.
had to adjust a bit to get it working
tf was better though..
then there was another game, that you played coop again the the computer... it was another HL mod.
Alien Swarm mod for UT2k4 is pretty awesome as well.
* alex_j is going to sleep
never seen it
* anonimasu yawnsw
damn... I'm looking at the rifle still... nice rifle.
I am too
a-l-p-h-a: which one?
the black one TS701, TS702
A-L-P-H-A: just remember ... that �1956 price tag was a bare stock, not an actual rifle ... barrel, action trigger etc are on top of that :)
look at 3500 comlpete
I'd just need a barrel + scope. Everything else I _could_ machine.
if I had the design specifics.
[22:18:51] <robin_sz> http://www.hps-tr.com/rigs.htm
look at the test rig at the bootm
robin_sz, this your stuff??
heh machining a full rifle..
A-L-P-H-A: nah, I just work with the guy on projects from time to time
that test rig is his pride and joy
I'd love to machine one though..
ok.. bye guys
but that'd be illegal over here..
See you alex.
omg? people actually buy this stuff at these prices?
holy crap! wow.
I saw somthing
serious competitors though, not your average guy
A-L-P-H-A: you sw someting?
[22:22:16] <anonimasu> http://www.dctechs.com/rifle.htm
* robin_sz guesses
is it the AR15 from solid project?
no, but I've seen taht also..
I know a guy that's a gunsmith.. he claimed a cnc machine could never reach enough precision.. :D
for a rifle..
I was refering to people buying these things at these prices. :)
anonimasu, does that thing fire?
for the barrel, possibly so
it dosent have a barrel.. but probably..
barrels are typically machined to within +- 1/10th
how manu 0,000 is that
anonimasu, uh, does the gunsmiff know that a CNC machine can get into 0.00001"?
of a thou
they file all stuff...
they turn it in lathes
yeah but mechanism..
I didnt argue too much
the mechanism isnt that precise
but the barrel is
although they do collector weapons...
cant remember the website..
some famous french ones..
for me, its just a tool I use for my sport
not a gun nut, I dont even get it out of its bag from one competition to the next
I do worry about the guys that *really* like em .. the ones who wear camo gear for breakfast
yeah I do too..
that should be enough reason to ban them from ownership
he dosent know about how precise cnc machining can be though..
they do it he traditional way..
the guy I know is a talented machinist
just bought a HAAS vmc
he knows whats what
the handgrip project will save him *hours*
machining that thing on a good VMC wont take that many minutes ;)
theres about 40 parts
hell probably sub out the big chunk still, but do all the small parts in house
he is a very talented machinist though
I'm off for a little bit.
clean up the mess in the shop I made earlier.
bleh, I feel like cad drawing somthing.
ear is red
was on a couple hour conference call to chicago
chewed off by angry cutomer
I have a headset for that
Naw, I am the advisor to a University of Illinois engineering senior project
if only they reallised ...
They are assigned to solve an optical analysis problem having to do with my encoder invention
Sponsored by ITW
so it involves Hard Sums (tm)
Things are gettin a little weird here....
ITW has even turned on my 401k retirement plan
whatever that is
I am not an employee
I wish my 401k?
I resigned to start a business
whats a 401K
A company mached funded retirement plan
in addition to a pension
we have similar things here
I know what it is...why they are doing this
to make yo happy?
My mirror heater patent expires in 2008
They still use my cam program to make it
to make you not want to spend your life machining things and want to work more for them?
uh huh ...
I am the only one who knows how it really works
total sales have now been 0.5 billion
so in 2008, you *could* set up doing it yourself or go to Ford or GM and sell the expertise
too bad They don't give percentages huh?
Well they are thinking about that I think
They want me to come back
I don't want to...I am having a good time with my business
les: being a consultant is profitable
buy that spindle and toolchanger :)
anyway in a couple years there will be some issues to deal with
automate your production..
with the heaters?
and work part time as consultant ;)
and push more $ into your company
and onto your retirement..
anon...I do just that
les: seen the ROSHH stuff that hitting the eu electronics industry?
restriction of substances hazardous to health
liek .. can only be built with lead-free solder
oh the bismuth stuff
worse ... you cant use certain chemicals in production
even if they dont end up in finished product
already having problems with that when I try to repair a circuit board
loads and loads
theres huge list
eu's a stupid thing
Hmmm the Heaters are produce in the UK
and this applies to parts sourced overseas too
I had to use toluene, ortho xylene, and tri methyl benzene in the ink solvent system
bet those are on the list
RoHs it is ..
I must use those...I am practically having to dissolve polythene
actually its a smalller list than I though
robin_sz : hey question about powder coating, if I have a part, that I can only clean or blast off certian parts of the coat, and then if the old coat is protected from getting a new coat, will that cause problems in the oven?
[23:00:04] <robin_sz> http://www.ul-europe.com/en/solutions/services/rscs.php
actually high molecular weight ethylene vinyl acetate bolck co polymer
Lead � Pb
Mercury - Hg
Cadmium - Cd
gezr: depends on what the old coat is
Hexavalent Chromium Cr (VI)
just a black
0.1 %Polybrominated biphenyls � PBB
if its a powder black
Polybrominated diphenyl ethers - PBDE
sorry for scrolling a bit
if its a cellulose black ..
cellulose black, hmm, I dont nor will I be able to test I dont guess, damn, Im gonna have to remove with another method, what do you recomend?
Hmmm UL...just down the street from me when I was in Chicago
oh cool, okay, great
robin_sz : thanks :)
Most of the things I see are related to PCBs
it wont work on epoxy and polyester powder, but then, if it doesnt , you dont care anyway
Is this a veiled attempt at just insuring they are all made in China?
the chinese can probably make them by the same standards we use anyway
it used to be china = crap
not so anymore
has a chinese built audio amp in to look over
copy of a "Crest" .. US make
the chinese one was neater
was only low power, but theyd done a neat job
(750W RMS a side)
Hope they don't discover turkey hunting...
sounds like my kinda amp
bit small no?
750W RMS isnt small ;)
my mate builds them up to 2K a side
BIG toroids :)
small? heh...you know what I am running in the music room.
my car amp is at 1,5kw
ha...is it enough?
not 1.5kw RMS though
it's more then enough
I used to be an audio design engineer at Shure brothers
long time ago
I'll bring my test load and a power meter :)
1.5kw out is going to be 2kw in, minimum
That reminds me...I need sitar strings
2kw @12V ...
robin: class ab I use average 65% eff
no big sitar
It's heel to string up
I played the baby sitar once,
* anonimasu yawns
the trick is to get the meend just right...shaping that bridge so it buzzes just so
sitars are cool anon...really
is there any setup howto for emc anywhere?
yeah they are
I am just a bit tired
just the wiki
hm, does that cover setting up the max speeds?
don't know...but just MAX_VELOCITY in the ini
hmm, I wonder whats limiting my machine then :/
my rapids are awefully slow..
that will set it for g00 moves
my g00 moves moves < 1000mm/min
more like 400mm/min
I keep them as slow as I can...no need to wear the bakllscrews
my laser is slow in rapids too
I want my machine to be fast :/
mine are at...
60m per axis, 84 combined max speed
75 mm/s right now
what's the max pulserate I can get out of a 500mhz
but very few rapids
* robin_sz nods
its feeds tha count
anonimasu: typically 20khz is max on almost anything
hm, I tried changing the feed but it didnt seem to make a difference..
bleh.. that's awfully slow..
I can go to about 0.3 m/s
you might get more ...
not guranateed though
that is 75% of critical speed on the ballscrews
and at 100% it goes apeshit?
hm, I'll increast the multiplier of the geckos then..
well if I needed more I would fit Higher pitch ballscrews
I have torque to burn
well.. I guess I should just throw $ on a vital card soon.
servos go fast!
but that sets me back about $1400 with amps.
I have servos already..
but I cant crank out enough pulses for them..
I'd need a pulsegen
copley 12A8 $75 on ebay...
I cant shop on ebay
20 amps peak
no one ships to sweden..
I need about 800w peak..
just trun up the pulse multiplier on the gecko
oh...I could get em and ship em to you if you really want
when I get some time...
jmk has some 'free' servos
les: yeah, I need to save up for a vital card first
or possibly cheap anyway
I am going to buy a bunch I think...normal prive is $300
and I have a mill to retrofit
peak power is 1800w
about the same as mine
that's about 2hp isnt it?
almost exactly the same
12 amp 90 v continuous
with a heat sink
is that the spindle ? (just making sure)
no the axis drive servos
your servos have more hp then my spindle
although not as much torque ;)
I have to push around a 500 kG gantry
I'll try setting my geckos to a larger multiplier tomorrow..
I wonder how that will affect accuracy..
but that probably wouldnt matter that much..
I am a bit anxious to get the BP series II in here
first of march
that'll be a nice workhorse
I think we will be buying somthing like that at work soon
I need it for the engineering side
I'd love to retrofit it with servos/steppers
since the gantry is busy doing wood
I will use motenc-100, 3 SEM mt-44 servos, Copley amps, and the estop system for my gantry shown on my website
It has proven very reliable
First I will set the machine outside the shop for cleaninf and perhaps painting
Poly tarp to protect it from weather
hm, how does this sound
heater inside to prevent any condensation
that sounds nice
I was thinking about the calculation for my step..
the heater is very important
5mm leadscrew.. to a 4:1 reduction..
that makes 5/4 = 1.25
lead and reduction sound typical
is that enough?
sounds about right
or rather small enough ;)
I have .002 mm per encoder tick
yeah.. but the 400 is the 5x pulse multiplier of the gecko..
On A slower metal only machine I will have a higher encoder resolution
because I run torque mode
prob .0005 mm
the max following error will be about 1.25/1000*128
don't need that for acurracy
just for smooth motion
since you double the encoder res..
that's before the drive faults..
well it X4 interpolates on the stg and motenc
gecko is 128 counts?
That will work at low speeds
it dosent fault as long as you dont estop it at full speed..
I have about hmmm 100 counts minferror
the 4:1 ratio make the servos plenty
400 count at rapid speed
I direct drive but that is because my ballscrew pitch is only 5 mm
I'd do that if I had enough torque to do that
I dont fancy belts that much
well wood cutting forces are almost zero
I need to go up to 10 mm/rev or more
but then I could not do metal
no matter since I am getting the BP
[23:40:55] <anonimasu> http://www.galilmc.com/products/motors/servomotors.html
if I had the ones in the middle I could probably direct drive..
I have the smaller ones..
the other ones were almost $1000 in sweden..
As I look...those would be fine for even a BP at 2:1 gearing or more
inertia is a little high...
but a good match for a BP
of the small ones?
or the ones in the middle..
The middle ones
I break endmills with the ones I have already.. but I dont like belts..
if anything I'd want to have one of thoose coupled gearboxes..
Inertia is about the same as 700kG linear using 5 mm direct drive
at 4:1 inertia is about 2800 kg linear equivalent
goes as the square of gear ratio
so motor inertia would limit accel
but it would be stable
no big problems
btw, do you know how the lathe support is going with em?
no...but I need a cnc lathe eventually
so I am interested
I am going to build one someday
but I need to get some projects finished
I gave away two when I moved
sorry I did that
I have a small lathe but it's too bad to cnc
Hardinges with burned old servo bandit controls
the ways are crap..
They were just too heavy to move
and the chuck bearings will wear out soon..
what lathe do you have?
a small one..
???? 1,5 M????
wait a sec
the one at work is alot larger though.
that would have a mass of several thousand kg
the one at work weighs a coupls of tonnes..
swing is max diameter of a circular work that can be held
I have a Boxford VSL 500
the one at work takes almost 1m ;)
It is about 1 ton I guess with the stand
but that lathe is scary..
the powerfeed has more watts then my spindle..
at my mill :)
I am letting someone use my lathe and mill right now....
I need a tiny cnc lathe.. maybe 5dm bed..
Charging him $US25 per hour
that's a good rate
But I am ending up having to teach him some
so the rate ends up being not so good
better that then having somone kill himself in your shop
Since that time displaces $100/hr engineering work
I had him sign some legal documents
So I will not be responsible
If he breks it
he buys it
he is making some kind of prototype
some golf thing
I turned some stuff in some nasty steel the other week..
the customer was standing next to me.. and I asked him about how close he wanted it..
I have no idea..
it sent sparks when cutting it..
err turning ;)
loads of sparks
hmmm rpm a bit high
I said "I'll make it 0.02 under"
the customer said "nah make it exact"
"how much exact would you like to pay for?"
the mitutuyo caliper show:ed 0 between the two pices.
I had it exact already but I was going to take it down so he could mount it without hand polishing it ;)
he was actually going to use a angle grinder first.. to get it there.
yup a 10 mm rod in a 10 mm hole is a press fit
he didnt have any idea about how close 0 is..
or well 0.02
