ive used regular plumber's solder to hold drills in extensions
i wonder if you could crimp the ferrules on and pull it up with another collet like the tormach system
one problem with the ferrule idea is if the cutting portion is larger than the shank diameter
you wont be able to get the compression nut off
fenn: the nuts are cheap
I think a nut and a ferrule together are under $1 when buying say 10 of each
oh so you'd just leave it on the cutter?
i was thinking about the tormach-esque scheme
but in that case you could have a special split fitting
the tormach scheme requires a drawbar as well
drawbar hole in a small spindle would be a challenge to drill
long small hole
assume spindle is 3-4 inches long, and 1/8" tools
ok, so its not some metallurgy thing like you'd want to use difficult to machine steel for the spindle
well, I would want to use good steel for the spindle
and good steel can be tough to machine, depending on what it is
it would also be tricky to get the drawbar hole to stay centered the entire length
it doesn't have to be a 1/8" hole does it?
I'm trying to decide if making the drawbar bigger than the tool would work
hm, why not ream the hole?
on a lathe
you gotta drill it first
reamer won't make it more concentric anyway
even on the lathe, drills aren't inherently concentric, and the reamer will follow the drill
Is there more common name for those panel mount breakers that sort resemble and can be used as a switch?
you'd have to bore it to have it concentric
panel mount breaker
well, what about gun drilling? :)
I don't have a gun drill
you have to bore that first too
drill, bore, and sometimes ream
gun drills drill from the solid
to start a gun drill.
oh, to start it
it depends on the system, some drills start from solid
but those are way more expensive
starting is no problem, its not deep
most need a to-size pocket to start in
even if I was just drilling it with a twist drill, I'd bore one drill diameter deep to ensure the drill starts on center
well a gun drill looks simple enough to make
it will wander off-center anyway, thats what twist drills do, but....
How weird... 80V max http://cgi.ebay.com/CARLING-SWITCH-25A-PANEL-MOUNT-BREAKER-NEW_W0QQitemZ320138226449QQihZ011QQcategoryZ109556QQrdZ1QQssPageNameZWD1VQQtrksidZp1638.m118.l1247QQcmdZViewItem
gun drills use 1000+ psi forced lube through the center to remove chips
modern gun drills have multiple cutting edges and pads in specific places
to keep the forces balanced and the drill true
but a basic gun drill is pretty simple, yes
and a pump from a power steering system will give you the pressure you need for the coolant.
well, how did they do it in 1776 then?
they used the simpler ones that still wander around a bit
getting back to the original problem - my plan is to design a small-tool spindle that doesn't need a drawbar hole
then I don't have to make a gundrill from bits of junk
tiny gun drills: http://www.sterlinggundrills.com/graphics/solid-carbide-shank.gif
.053" solid carbide
if you have to ask you can't afford it
oh, theres a price list
and sometimes even if you don't have to ask you can't afford.
I don't want to afford that
but it's cute!
and i was expecting it to cost 175-200
looks like you can get a "standard" gun drill, 1/8" for $83
all you need is a high pressure pump
really you don't need a gun drill
0.0001 feed per rev = 10000 turns per inch = 30000 turns for a 3" long spindle = half an hour at 1000 RPM
you can go 10-20x diameter with a high end drill from titex or guhring
the trick in any case is the pressure
hmm, 1/8" gun drill, wants 1500 PSI at 1 GPM
what does pressure have to do with concentricity?
oh, i thought we were going deep?
i'd also choose a titex or guhring for concentricty as well
they're very, very good drills, but they cost like 15 bucks for 1/8"
i guess you could shave the OD of the spindle to balance
still cheaper than a gun, and should be more accurate
fenn: one approach is to drill first, then put it between centers (using the drill hole) and turn the OD concentric to the hole instead of the other way around
only valid if the hole is straight but off center
if the hole curves, all bets are off
get a hammer :)
so, is there anything wrong with just peck drilling?
other than dying of old age before the hole is done?
doesn't help with the hole geometry
well, you got a CNC lathe remember
just with chip clearance
just like pressure doesn't have anything to do with accuracy, neither does pecking
cnc lathe with a manual tailstock
it saves on having to get through-hole drill bits and make a coolant delivery system
put the drill in the cross slide
anyway, we keep going back to deep hole drilling
how deep is this hole
I'm a damned engineer - that means I use my brain to design things that don't need difficult machining operations
toastydeath: there isn't one, in my design
(we're talking about spindles for 1/8" shank carbide tools)
I want a front mount design, fenn is talking about a design that uses a drawbar (so it needs a long skinny drawbar hole)
i hear pcb drilling machines go through boxes of drill bits a day
Do you plan on an automatic tool changer? :-)
they run a bit fast 60k rpm
20-30K will work if you back off on feeds - a hobby machine doesn't need the thoughput of a commercial one
harbor fright has a 1/4 HP 15,000 RPM flexshaft set (foredom clone) for $70, that is a candidate for the motor
Oh. It's a hobby machine. Why aren't you using Mach then? EMC is for professional machines. :-)
any way dremel== ready made spindle for 30k
Do you plan on reworking the bearings on the flexshaft set?
yes - I wouldn't use the flex part at all - too much vibration and slop
probably belt drive (o-ring type belt, or small flat), to allow some latitude on speed
no old sewing machines laying around?
ideally the spindle/motor assembly could be used on the mill for PC boards, or as a toolpost grinder, etc on the lathe
hmm ubuntu installed, steppers working, first g code sorta working, 1 am /me can go home now
fenn: nope, good idea tho
not my idea.. saw it on buildyouridea.com
oop.. salad shooter
[01:10:29] <fenn> http://buildyouridea.com/cnc/pcb_drill/pcb_drill.html
prolly want something without a fan
thats a nice little spindle
can't tell how he's holding the tools in though
looks like a collet and nut
[01:15:11] <jmkasunich> http://www.buildyouridea.com/cnc/spindle_05/spindle_05.html
even simpler - setscrew
clearly he's using heat shrink
probably something like this http://buildyouridea.com/cnc/pcbmill/spindle.html
(seems guaranteed to have runout
that's not the same spindle
Have you looked at "outrunner" motors? Small, three phase brushless...
* fenn wonders how many spindles this guy has
I first started thinking about fast spindles a year ago, after seeing outrunner motor sites
how fast do they go?
Seems like a neat way to go.
lerman: the ones I saw were for model airplanes
stunning power density, but they relied on the passing air for cooling
and also were intermittent duty, a few minutes at a time max
cool compressed air and blow it over the motor?
put a pc fan on it
water jacket cooling
Get one of the larger ones and run it at lower load.
Put a prop on it and use that to blow air thru it.
what's the limiting factor for belt ratios?
fenn: usually slipping on the small pulley
since as the ratio gets more extreme, that pulley loses wrap angle
you can use a tensioner
to increase the wrap angle?
Unless you use an idler to increase the wrap -- or put them an infinite distance apart.
I suppose, but thats another high speed shaft
unless you make the tension pulley large, but then it gets hard to fit it in
you could do like those ultra high speed spindles and just spin the floating bit with a tire
"all of the "milling" to make the flat sections was done with a sander" from the spindle page :-)
As far as heat it concerned, they are probably no less efficient than other motors. So, just pick one with the right size.
lerman: where are you talking about "picking" one from?
the sites I saw were mostly DIY
rewinding CD-ROM motors and such
I think they are commercially available, now.
the few that I did see for sale had prices that were much higher than the HF $70 foredom clone
[01:25:11] <lerman> http://www.hobby-lobby.com/brushless-axi2208.htm
you pay for that power-to-weight ratio - worth it in a plan, not on a machine
How long do you think a HF foredom clone will last?
the hobby motor prices aren't as bad as I expected
but theres no info about power there
need torque, or watts, or something, so you can tell what is what
vacuum cleaner probably has a pretty fast motor in it
knowing what size plane it can pull isn't very usefull ;-(
model airplane motors should have the wattage rating
And they are cheap enough that you can afford a hearing aid after you go deaf listining to the vacuum cleaner motor.
Some of the motors on the DIY lists were over a HP. (if I recall correctly).
juiceman junior.. quiet, fast, powerful
vacuum motors are probably in the same class (if not worse) then the HF foredom clone
jig grinder spindle!
toastydeath: got one laying around to send me?
i have an invisible one i can send you
in an invisible box!
the sewing machine arm might have a nice bearinged shaft in it. the rear always had that big hand starter wheel and felt really solid
looks like the airplane motors run on 12V 18A = ~200 watts = ~/14 HP (assuming it all gets turned into spin, not hot)
toastydeath: its a deal - I'll send you some invisible money
i am glad this can work out for us both
1hp ~= 2800watts?
a lot goes to heating the air'
tomp: let me introduce you to "units": http://www.gnu.org/software/units/
thx fenn I was being sarc/silly
oh~~ (sarcasm marks)
Max continuous power -> 1500 watts. $89.99
still, I'm amazed at that power per dollar - they've come a long way in a year or two
I saw that. Also, the power per unit weight.
well, power per weight was always impressive - has to be for planes
* fenn disassembles the juicer
I don't really know if that would work in your application, and considering that you also need a power supply/VFD, it's expensive.
But... when you were done, it's a heck of a lot more motor than a HF foredom clone.
the permanent magnets in an environment with metal chips is kind of un-nerving
thats for sure
Kits are available for these things, so if you want to save money, you could DIY.
hmm, 400W max, 30A, $45 (smaller size, 30mm instead of 40)
I assume that is continuous also.
35A drive is $55
car battery and charger to run it......
I didn't see anything on maximum voltage or speed. Kv is around 500 rpm/volt (depending on model).
the controllers are all 6-15V
so figure 15V tops, thats 7500 RPM unless I'm being mental math imparied
[01:44:01] <BigJohnT> http://www.science-city.com/918vdchispel.html
but not math impaired.
BigJohnT: much less power than we're talking about
1.98A at 18V is under 36 watts
we're talking about things that would run 10x that
Not clear though where the maximum voltage rating would come from.
well, the controller rating comes from the mosfets
the motor limit would be fuzzier - as you increase volts and speed you also increase frequency, and eventually core loss in the motor will result in overheating
Question is whether you could use a different controller and run the speed up higher. Physical forces on the rotor, unbalance...
outrunners are probably more sensitive to that, since the rotating parts are bigger
Ah. Core losses. As I recall, they use stacks of thin stock. I would think that the right material should me OK at 15 or 30K rpm.
yet another project
Balance the magnets when the rotor is assembled.
Use 'premium' bearings.
I took apart a few cdrom and similar motors back when I first started reading about those - didn't do anything with them tho
too many projects, too little time
the ability to dynamically balance "things" in general would be handy to have
I doubt that static balancing would be good enough when you get into the 30K range
Some of the turbo threads I've seen include a reference to a DIY dynamic balancer. (yet another project)
I should get back to work on the project at hand
thanks for the ideas and links - that brushless place is bookmarked
hmm.. 52x cd-rom is 10krpm?
should be closer to 15k - 1x is 300RPM I think
how about a homopolar motor - no magnets, high speed, no brush arcing
homopolor motors always have brushes, and they usually carry very very high currents
yes but there is no commutation
there is sliding contact, thats what matters
when i was reading about pancake motors, they said that they could reach very high speeds without brush wear because there was very little inductance
its the arcing that causes brush wear, not sliding contact
but i dunno what happens with low voltage high current and no inductance
fenn: with a homopolar, its aggravated because one of the brushes usually has to be at a large radius, so the surface speed is high
i'm not sure if its technically a homopolar motor, but you could ahve a "U" shaped toroid that carries the current
uh, toroid is the wrong word
a U shape isn't a toroid
a horseshoe magnet?
for bigger motors you can go to hobbycity www.hobbycity.com
hmm i guess there isnt a word for this shape
shipping is slow, but the prices are right
take only the skin of a cylinder, and drill a hole through it axially
fenn: In response to your question "fenn: but i dunno what happens with low voltage high current and no inductance". You get this (seriously) --> http://www.action-electronics.com/grc/wed550.jpg
an electric bicycle used one of those airplane motors, controller and a lipo battery http://www.youtube.com/watch?v=Qxh_cMrIyVI
They're like 0.5V 100 or 400 amps. At least that's what the Cooper Tools engineer told me.
Cooper Tools is the parent company of weller
why would they bother changing voltages?
just set it up to use 120v
eric_U: because of the tips
it IS 120VAC on primary, secondary is 0.5V 100-400Amps
there is an electric bike company that blows away airplane motors, the stator is probably too small on the airplane outrunners
they certainly have the power though
the battery in that utube video is probably $3-400
I tried a similar design with a roller that presses on the rubber tire, the efficiency in the transmission was abysmal, I never tested but probably in the range of 50-70%
*I never tested scientifically
yes, the successful bikes have powered hubs
yeah, I've been trying to get a hold of one of those cheaply for a while
I think a system is about 1k
hmm, by system do you mean a retrofit kit?
yes, and a decent set of batteries
oh, not bad
[02:22:13] <eric_U> http://www.youtube.com/watch?v=gdyV6cZ4ZMg
probably a little more :)
interesting, series-type hybrid?

i wonder why no fairing over the rear wheel
don't need it I guess

ebay is a good source for the dewalt batteries
they seem to go for right around $100
I'm hoping to have an airplane with them in it
I have some of the smaller a123 batteries, going to put them in a plane soon
hey whats up everyone
im tryin to come up with the front panel for my machine with the monitor.
that's so much fun
just trying to find wich buttons i need and etc.
you could do like Haas, throw every button in the world on there and hope people like it
i want 1 through 9 an enter button, a select button, xyz movement buttons
eric_U: i see the 36V dewalt is made with the A123's http://www.slkelectronics.com/DeWalt/packs.htm
that's right, they are amazing
in my use of EMC, I think 1-9 are some of the keys I use least often
a little heavier than lipo
cradek what buttons do u think would be most beneficial?
the most frequent things to do at the keyboard are jog and type MDI commands
a jogwheel is better for jogging of course
what is an mdi command?
you might want to spend a little time using emc before you try to design a panel for it
just use a keyboard and monitor and mouse for a while
you suggest just using the comp?
if you have never used cnc before, yes
starting by designing and building a panel just means you will have to do it again
It's definitely a secondary concern for me
what should I be prepared for when those cards come in terms of what i do first, and blah blah
you need to figure out what connects where
getting the cards in you control cabinet may not be easy either
im just gunna throw them in the comptuer
did you get 50 pin ribbon cable?
eric_U THEY DONT COME WITH ANY? LOL
is it standard computer type ribbon cable?
hate to say it, but I told you that
I have to have a few around
old scsi cables

once i hook it all up to the machine what do i do?

"and you don't have to wait light years for the next Windows to come out either" [clueless IBM marketing dork selling OS/2 Warp, ca. 1994]
hey, it's a figure of speech
but thanks for obliquely calling me a clueless dork
pretty sure you used it as a distance
I wonder how they add z to that. Pen number?
I bet it's something like that
you could definitely use pen widths as heights
If that's the case, then the rs232 might make sense as an ordinary old style plotter interface.
(if you can still find anything that will run a pen plotter)
I don't agree that jepler is a clueless dork
ok maybe I need to explain that
* rayh glances at his plotter gathering dust in the corner.
this was an OS2 conference (a bunch of geeks excited about a new OS) and the marketing type used light-year as a period of time, not distance
everyone in the crowd knew a light-year is a distance measurement
I seem to remember something in the os2 stuff about that.
and that's why Microsoft won the OS war of the 90s?
so they were dumbstruck when he said "will have to wait light years"
yes I'm sure it was all his fault
Nah they won because os2 was a nightmare a lot like cpm86
windows 95 was actually quite neat
* skunkworks bought a os2 copy
(actually so was os2 warp)
I ran it for atleast a month.
What! No one ran CPM.
warp came with productivity apps including a decent word processor
I remember wishing for the CPM card for my Commodore 64 (not that I had any idea what software I could run with it)
I am almost thinking that the C128 had cpm..
in 128 mode
yes it did
You youngsters were probably playing pack man back then.
we had a CPM box on IEEE488 off the back of out PET
I think 99.9% of the time we ran our C128 in c64 mode.
skunkworks: did you have the nice color monitor? I remember wanting one pretty bad
Yes - it was rgb iirc
I seem to remember some nightmare accounting and inventory package on it.
and 80 column in c128 mode.
Heathkit H89 - that used CPM, I think. The first machine I bought.
my "monitor" was a B&W TV with the horiz output tube bad, so the letters at the top of the screen were 3x as tall as at the bottom of the screen
there never was much C128 software AFAIR -- but I would have loved to have terminal software that could run in native 80-column mode

cradek: the font didn't bother me so much as the scrolling speed
A student and I built the student radio station automation system and ran it with a RadShack model one. Lots of peeks and pokes.
we had gotten a serial card for the 128.. I don't think I ever got it working correctly
trying to run some old serial printers
I had some parallel printer converter board so I used a PC-style daisy wheel printer
and I eventually tore the line drivers out of a normal modem to hook up to the (ttl level serial) user port
so did we. It was a comador serial to parallel. We bought a star dot-matrix (ibm style)
I miss the daisy wheel - it was cool. It had a sheet feeder. I'd start it printing something and close the door, it was so loud :-)
at first though we had a daisy wheel printer/typewriter that had a commadore serial port in it.
word proccessing has come a long way :)
at least with the daisy wheel there was no possibility of comic sans

SWPadnos: I had an idea regarding auto/manual mode switch... What if I used it as a main power switch?
do you still want that controlfor the spindle?
or just the vac?
Just the vac or dry runs
ok, so you want a spindle inhibit control, and independent vacuum power
SWPadnos: I just figured that if I ever decide to add spray lube, it would be in parallel to spindle.
no, you probably want separate control of mist or flood coolant
though it would run more or less all the time the spindle is on, so who knows :)
SWPadnos: Right, but also might need to operate sepeately for maintenance purposes
do you mean like the vac?
ie, "I'm cleaning with the PC off, so I want to turn on the mist"?
are you expecting lube to be an outlet like the spindle/vac?
maybe flush out old coolant, etc.
replace with new, use the pump to drain out, etc
ok, "lube system maintenance" :)
that should be relatively rare, and you could always fire up the PC and do an M<whatever> to turn coolant on/off
If I didn't want the BRB to kill all, it really woudn't matter.
or, if it's a normal wall plug, just plug it into the wall
lube and vacuum aren't really safety issues, though they may as well be killed with e-stop
SWPadnos: I was also thinking, of using BRB as old fashoine stop/off. No real reason not to use it in that way that I can think of.
instead of a master power switch?
what is BRB?
big red button
like BRS on old IBM PCs :)
SWPadnos: Master Power Switch would become Manual/OFF/Auto + Grn START/BRB
cradek, do you still have that link to the little square AC outlets you used?
JymmmEMC, hmmm. I don't like it
SWPadnos: no I just had them
on my machine I have manual control of all functions and I use relay logic to not let emc controler come out of estop in manual mode
SWPadnos: due to the three way switch?
or another product on http://www.allelectronics.com/cgi-bin/category/915/A.C._Sockets.html
hmmm. that could have been it
JymmmEMC, I wouldn't assume that everything should have power removed for estop
it depends on the drives - if the OEM650 can "brake", then it probably needs power to do so
at least control power
conceptually, the master switch should turn on the controls (which could include the computer)
the e-stop should control power to anything that could be dangerous - motion, spindle, laser - whatever
you wouldn't want to shut off the PC for an e-stop
SWPadnos: I really dont plan on having the control box turn on/off the computer.
I know - this is conceptual talk here - there may be things (ssuch asthe breakout board) that you want to keep powered even during e-stop
SWPadnos: Ok, I'll keep looking for a panel mount toggle breaker - just was having a hard time finding a 15A one.
20A I have already, with finger guard.
use the 20A then
the breaker had better not be an actual safety device - it's probably too slow
SWPadnos: That was my intension. Thus why I was looking for a 15A one.
SWPadnos: or should I just use a .22LR =)
you have a 12A spindle, and a 3-4A vacuum, plus whatever the controls take, plus the motors/drives
you probably need the 20A breaker
SWPadnos: Ah, remember I have a speed control on the dustvac to reduce the draw.
12A for the router + 3xstepper motor and drive + the controls (contactors take a few watts each when on) + shop-vac at 25% = 20A breaker ;)
SWPadnos: You forgot the 4A for the PC+crt
is that going to be on the master breaker?
or just the same circuit?
SWPadnos: Same circuit on the 100A panel
SWPadnos: So, were up to 24A on a 20A circuit =)
I guess there could be problems then ;)
SWPadnos: I slow down the spindle to 20K or so, which drops its run draw (just have to deal with startup), plus the speed control to reduce the draw on the ductvac from 7A to just under 5A
JymmmEMC: that calls out for troubke
alex_joni: Yep =)
I wouldn't think about putting anything less than a 32A circuit there..
I'd say that you do *not* want a manual "on" setting for both spindle and vac (and lube)
alex_joni: Out of my control - I reant.
if you forget they're on, and flip the master breaker, pop goes the breaker (in hte panel)
SWPadnos: lets forget the lube, it was just a thought for future expansion (thinking ahead is all)
There is 220VAC in the garage (for the dryer) on dual 40A breakers I could steal, but well, you know.
if you have to argue with the GF about whether to continue machining something or wash your clothes, you're in a bad situation
heh, yep. But she already knows not to run anything while the machine is going.
I had to map out the panel a long time ago... I've done alot of electrical rewiring around here already replacing ancient outlets and wall switches that were arching.
contractor packs ftw!!!
In the garage, they had a 3 prog outlet, but never connecte the ground wire that already existed in the gang box... WTH?!
yep. I'm always amazed at how little electrical stuff costs - like $1 or so for an outlet
SWPadnos: $0.50 baby
I usually get the industrial grade ;)
SWPadnos: If it was my place, there would be a 100A panel for the garage alone.
don't bet on it - it gets expensive to add a second feed to your house ...
I was as unlucky as possible in that regard - the panel is literally on the opposite corner of the house from where the machine shop had to go
I ended up running about 100 feet of 8ga out to a sub-panel in the garage
SWPadnos: but worth it, and you only have to do it once.
OT Does the "Banging" solution sound right? http://www.doityourself.com/stry/waterhammer
interesting - digikey has similar outlets (that may be higher quality), for less than All Electronics
[18:23:50] <SWPadnos> http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=Q227-ND
JymmmEMC, could be right
SWPadnos: k, can't hurt to try. I have a water wrench
I suppose I should go get the trash can before it's buried in snow
hey JymmmEMC - take a look at this: http://www.drobo.com/products_droboshare.aspx
I think that'll be at MacWorld
yay drobo :)
the NAS interface is new and looks cool
they have NAS now?
SWPadnos: build it or external?
basically converts the drobo from USB2 to gigE
is eth built inside, or external to it
look at the link, silly! :)
it's a separate unit that you plug the drobo into, which has the ethernet interface
$200 for a usb to eth adapter, you on crack?!
that's the NAS box
With DroboShare you can choose NTFS (Windows), HFS+ (Mac OS X), EXT3 (Linux) or FAT32 (Various)
that sure is worth 200$ to add to the drobo
along with adding two drobos
[18:37:33] <JymmmEMC> http://www.thecus.com/products_over.php?cid=12&pid=32&PHPSESSID=89f8ea0c052a84f9d45876293e33753c
alex_joni: but not at the same time I seriously doubt
yes - "shares 1 or 2 drobos"
we can take a look at MacWorld
I have this thing againest external PS's
DroboShare can host up to two Drobos, allowing capacities of up to 8TB of storage today, scaling to 32TB as larger disk drives become available.
argh digikey uses flash now? wtf!!
fenn: get with this century already
fenn: If you dont like flash because of the ads, thats one thing (and easily fixed), if it's just because it's flash, I'd like to know why
flash is slow an crappy and fucks up every little thing because it's non-standard
flash is rarely useful in the situations where it's used
they have bad support for 64-bit OSes, and Linux specifically
fenn: I think it works surprisingly well
i'm browsing a catalog, i dont want some stupid page animation script failing and taking down the entire site
fenn, there should be a link to the "classic search"
or some such
Flash is the only format that I know of that you can combine, text, graphics (both raster and vector), sounds, video and combine them all into a single-fiel format for easy transport. Hell you can even render PS directory inside a swf file. and even convert it to an aexecutable and publish it on a cd/dvd without any installation to the client machien if you wanted to.
that assumes a lot about the client machine
It can even embed a PDF file + viewer
fenn: the boom while browsing pages is something I've only seen java do
SWPadnos: p2 and up that I've tried it on.
it's easy when you stick to the Windows and Mac world, not so easy when you go to Linux
oh great, so instead of just giving me a pdf file, i have to look at it inside your stupid flash animation, assuming it actually works
well, linux still dosent have decent graphics drivers.
and they don't publish the specs, so it's hard to make an open-source viewer
sure it does
fenn: flash works for 95% of the people on the web..
fenn: flash rendering a pdf fiel is actually far faster than most pdf readers actually.
fascism works for 96% of the dictatorships out there..
SWPadnos: Yes, they do.
graphics drivers are mostly independent of the applications that use them - you can use xorg/xfree86, you can buy an x server
fenn: stop fucking around, if you like it use a textmode browser..
anonimasu: that's my point, i can't
fenn: you are just dicscontent because it's not opensource
there is an open source flash player, it just sucks
JymmmEMC, ok - the main thing I've heard about flash is "why can't I get it for my 64-bit Linux system" :)
i happen to be using the non-free plugin fwiw
SWPadnos: Hell, there's a lot of apps that aren't 64b aware, not just flash.
anonimasu, this particular complaint is that the database search function is in a flash app - that's an unnecessary complication
SWPadnos: agreed that's stupid
I saw that version once, and I hated it
SWPadnos: but flash certainly dosent suck :p
luckily, they did have a classic search link at the time
actually its the catalog page that's only available in flash
as I said, flash is often used in places where it's inappropriate
They're offloading the UI to the client via flash, Which is far faster than using AJAX which gets dawg slow
a catalog page doesn't have any UI!
fenn, go back to digikey.com, and there should be a link for the old search
its not search that's a problem its the catalog page
click to zoom
anyway. i can download the entire catalog as pdf
oh - why use the catalog page? :)
or if you can read 3py type
because otherwise it's hard to find similar products from just a product information page
JymmmEMC, this shows what flash does for you: http://dkc1.digikey.com/us/en/pdf/Current.html
fenn, there's usually a link on the product page for more info, which will have a link to a single-page PDF of the page that product is on
mostly i'm just disappointed because i thought the people at digikey were smarter than that
they were smart enough to get rid of the flash-based search in a hurry
I thikn it was there for less than one day before the "old version" link was put up
no, the single-page pdf is what i'm whining about
er, lack of it
what product are you looking at?
[19:02:35] <fenn> http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=Q227-ND
if it's in the catalog, there's always been a link to the catalog page
oh. they screwed that up. damn, I hadn't noticed
fenn: Jsut download the whole catalog http://pdfcatalog.digikey.com/T081/DigiKey.pdf
wow - totally screwed itup - how friggin annoying
if I could use my own PDF reader, I could do things like - I don't know - drag the damned page around
SWPadnos: what reader are you using?
fenn: Eeeesh it's still there http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=PSL-CB-ND
I normally use acrobat reader onthis PC, but that stupid flash app doesn't actually let me do that
Just use the search in the top right corner
JymmmEMC, now click the link for technical/catalog information
oh - that one has no catalog page
try the Q227-ND one
SWPadnos: I did, and got a link to a pdf
you'll see the problem. it isn't necessarily flash, it's the stupid UI they've decided to give us for looking at PDF files
that's a datasheet
yeah, click the PDF link
(at least they dont have flash animations for datasheets.. yet)
[19:06:51] <SWPadnos> http://digi-key.dirxion.com/Main.asp?from=emailafriend&pagenav=&bookid=1&pageindex=1467
SWPadnos: I did, and I got the pdf
for the catalog page, not the datasheet
no - that's not a catalog page, that's a datasheet
SWPadnos: what do you want the page the item is on?
as fenn pointed out, it's easier to see related items
this particular product doesn't have a catalog page
to see the stupid app they decided to make me use, go to digikey.com, search for Q227-ND, click the technical link, then click the catalog page link
ok i see what you mean now
bad interface, huh?
you can only use the scroll bars to move around the page
(or search, I guess)
dragging does soem zoom function it seems
There's NEXT/PREV at the top
and it's really slow and eradicates any handicapped accessibility features
but besides that.. it's FLASH
that's page by page - what if I zoom in so I can read a diagram, and then want to drag the page down to the price lists?
SWPadnos: what about it?
bzzzt! can't do that except with the scroll bars - there's no equivalent of the "hand" tool in adobe reader
or middle-click in any CAD app
ie, they decided that whatever my chosen application is is just wrong (sometimes I use Adobe, other times Foxit reader), and I have to use their less functional system that I don't know how to use yet
Well, I guess you no longer are going to order from digikey
I do admit that what THEY did, is totally fucked up from a UI perspective.
digikey's big thing is customer satisfaction
I sure as hell can't use their online catalog as well now
Well, the WAY they did it that is.
s/some/at least a few :P/
yes - it's been my experience that there are very few places where flash is used well, it's usually used to look - err - flashy
wow, digikey used to be the best for searching etc
actually the one I use has a different mouse option
yeah - the search still works, but the catalog is unusable now
I think I'll email them
care for your oppinion..
[19:14:42] <alex_joni> http://eneas.juve.ro/~juve/stuff/cpu.PNG
is that sign for a needed upgrade?
SWPadnos: Well, just download the pdf catalog.
I have the printed catalog, thank you :)
alex_joni: cool how'd you log that info?
alex_joni, no, that shows that you're hardly using what you have. get back to work!
SWPadnos: well.. I'm not that sure
21:13:38 up 139 days, 11:09, 3 users, load average: 0.23, 0.27, 0.22
the load average is still fairly low
I like the 30-minute average graph though - shows regular work hours :)
but there are times when it goes up beyond 1
13:16:38 up 117 days, 4:19, 14 users, load average: 11.63, 14.25, 8.58
alex_joni: Exactly, so GET YOUR ASS BACK TO WORK till it's solid green!
looks like a vacation in week 51 and 00
send your machine here, we need it
err - 52 and 00
cradek: ouch.. is that still useable?
oh yeah it's fine
it's always like that
this is a 2 x Xeon PIII @ 933MHz
it does file sharing (samba), and IMAP for the local subnet
sounds like it's probably plenty then
alex_joni: heh, add a graph for connections =)
JymmmEMC: I have.. they're always connected :P
21:08:57 up 175 days, 17:09, 2 users, load average: 0.00, 0.00, 0.00
I like the load here better :)
ok.. 'nuff for today
see you guys later (or mayeb tomorrow)
hey i'm setting up a new install in my office. did a cvs check out of trunk... compile says no tcl
also, no rtai..... did i get something wrong?
installed from liveCD 2.2.2
anyone? am i missing a simple pointer or something?
what "uname -a" says?
[19:23:21] <cradek> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2
[19:23:33] <cradek> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Ubuntu_5_10_and_6_06_from_source
just making sure: you do know you already have emc2 and don't have to compile it right?
probably that 'build-dep' thing. i'll try.
hmm - the motherboards I bought don't support the williamette cpu... - guess what I have 4 of..
I guess I didn't research it hard enough..'
cradek: thanks. it's rolling through now.
lewin1 is now known as lewing_
I love the sound of chips flying...
BigJohnT: machine running already?
running my cnc mill making parts
short production run of exhaust diverters in 6061 for air tools
well.. I'm off to bed..
good night all
where to send Polish translation of AXIS and interpreter ?
micges: "if you are a developer, simply check in the .po and .msg files after you have updated and tested them. If you are not a developer, then e-mail a developer the updated version of these files. .pot file.po file pattern"
hmm, any dev's got an email addy for micges?
can I send to emc-devel list ?
micges: i dont think it will allows file attachment
maybe you could upload to http://pastebin.ca
and post the urls here
I downloaded trunk few days ago and I translated only .po file. Is this enough ?
I am not familiar with the process, the only information I found is posted above, sorry
micges: you can send mail to emc-developers if you join it
attachments are accepted if they are below a certain size, which I think is 24kB
that would be a great way to submit your translation
and thanks so much for doing it
Hello all. I have a HAL-related question if anyone would be willing to entertain it.
GNieport: fire away, you can always just ask
Put the translation on the wiki and send out mail telling us about it.
some more information here if you translated AXIS: http://axis.unpy.net/translations
(Or -- if you know how -- check it in to the source tree).
thanks. I am setting up a new machine and using HAL to help tune the PID loops. I am having a bit of trouble with syntax when adding signals and pins.
I think "net" is the most useful command
This is 2.2.2 btw. i cannot get "newsig foo float" to work
well, net did work for the floats, but now not for the bits.
let me post an example
ok, please use http://pastebin.ca
if it's over a line or two
"net testbittwo<= m5i20.0.in-04" fails for invalid argument.
er, correct spacing
spaces around the <= ?
GNieport: what's the error message?
halcmd: net testbittwo <= motion.spindle-on
[23:33:56] <GNieport> http://pastebin.ca/855389
sorry, gui crawls
try halcmd at the shell, instead of using this gui tool
cradek: is this cpmmand a seggestion for me to try?
I'm just showing a similar thing worked for me, just like you had it
you are using halshow right?
yes, I opened it from within Axis.
ok, at a shell do halcmd -kf
then you'll get a halcmd prompt which is what I used
fwiw, I like to tune an axis with a gcode program that has a bunch of short g0 back and forth with g4 pauses... I don't think it's worth the trouble to try to set up position steps
<stdin>:0: pin 'm5i20.0.in-04' was already linked
ok, that's a much better error!
cradek: yes, just wanted to verify the dac was working before tearing up a ballscrew
(a pin can only be hooked to one signal)
i should be good now, thanks again
the verbose error messages help a layman like me
yes it helps if they are remotely related to the actual problem too!
good night all
