* anonimasu yawns
03paul_c 07bdi-4 * 10emc2/src/emc/drivers/sensoray/sensoray526.c: ADC routine fleshed out.
What are you doing up so early ??
oh, been to a lan party met some friends..
I've got a day off tomorrow for going ski-ing
paul_c: dont you ever sleep?
from time to time.
I see your cvs commits round the clock almost :)
* anonimasu makes a mental not to remember to play with nml tomorrow
* paul_c hands anonimasu a 3D rendering library with multiple pipelines
nice little example
Bed time for both of us....
no one chatting?
does bdi come with workgroup networking and file sharing?
just found out about linux and your site :)
could you guys give me some info like for start where can i dl the last version of emc ..
first off, what would you like to do? Do you have a mill?
well i need to control 3 axes
with step motor
you can download the bdi cd from :http://sherline.com/emc/
i have 3 motors (for 3 axes dahh...)
If you want to just check it out first, use the http://sherline.com/emc/BDI-Live_rc46.iso
it's a 'live' cd that will let you run from the cd without installing
it gives you a feel for the system
you will need at least 256 meg of memory
to use that one
the regular bdi:http://sherline.com/emc/bdi-4.16.iso
needs less memory to install, since it's going to the hard drive
i have a 514md DDR with 1.47 Ghz
should do the job :)
try installing it. If you have problems come back here and ask questions
thanx for the help :)
sure. good luck with everything
joe2000chevy: are you still there?
how's it going with the machine?
all done, i am changing out the router with a rotozip.
are things moving predictably now?
rotozip is var. speed from 15,000rpm to 30,000 rpm
yea, it moves great
you had a network question earlier?
i need to figure linux out tho....
yea, i do not no how to connect to it
the linux, is automatically on the net.
If you are doing cam with a windows machine, you might be able to use Samba to do the job
I'm not much help with this, but I think it might be what you need
Granted, I have never used Samba, myself.
how do i get a linux machine on the network?
Well, I haven't had any problems using my DSL router.
I guess my router acts as the gateway
when I did the install, I selected dhcp
Sorry, I'm not much help here on this one.
One of the other guys could help better
well it already connected, i just cant view it with windows.
and also the file sharing said it was not installed?
do you know what address it thinks it's at?
or something like that
you could use Ftp to put files on it
yea i looked at the clients on my router and see it connected....
find a ftp program and log in with your current user name and user password
i know one guy here does a remote access right?
I do remote access from my Mac
you can look at it with SSH or VNC
I use SSH to run my linux box from the mac
but you probably need to use Samba to transfer files more than anything
i have never used linux before so it new to me, but if it was windows i could setup vpn and also i set up vpn between offices also.
I will have to do some reasearch on this
since i do not know linux i need programs that autoinstall
is linux better the windows (i know it sound dumb) but i just found out about linux last week at work
i have been using windows since 3.0
I use linux and mac os X
used to use windows up to win98
so I'm not qualified to answer that
I like what I can do with linux and EMC
make machines run
then 3.11, 95, 98, 98se, me, 2000, 200 pro, xp, xp pro, nt 4.0, server 2003.... so i know windows well.
i heard about linux fedora 3 is it good ? the site was www.linuxiso.org if i recall correctly
I like the bdi disk that paul came up with. It's based on debian
it's very easy to install new programs with
just type int apt-get install program name and it gets done
ok so debian it is :)
use the bdi from the sherline site
it works very well
i used the total install on a machine, went seamless.
yea def. BDI for this project
pual did a great job setting that up
do he show who to connect the stepper to the PC
well, you might want to look on some of the yahoo groups for that kind of advise. Let me find a Url...
no thats with the board you get
i use the hobby cnc 3 axis board
[04:35:02] <danfalck> http://groups.yahoo.com/group/CAD_CAM_EDM_DRO
what do i need i have 3 stepper one PC with cd-rom and all , and a tranformator 120 VAC / 10VDC
stepper drivers (electronics to power the motors)
power supply for the drivers
cable to go from the parallel port to the drivers
joe2000chevy: do you have a good url for the board you are using?
10v is to low
i know it 10V DC with 7A
min. is 12v
i use a psu power suplly right now. jacked it up to 12.4v
24 volt transformer, bridge rectifier, capacator
here is my machine i just built http://www.cnczone.com/forums/showthread.php?t=8432
maybe i didn't explain it well... sorry my english is not perfect.. my stepper motor requier 10 VDC with 7 A
[04:40:24] <danfalck> http://www.mpja.com/productview.asp?product=15542+PS
yup that will work
oh is that what is on the label of the stepper motor?
it has also half step
do you have the stepper drives to power the motors?
mot really microstepping. altho i have mine set to 1/2 setp
stepper drives?? no i don't think so
is it the card that make me controle the motor
check out this site: http://geckodrives.com/
these are like 'amplifiers' to make your motors move
cool, qwerty is from Toronto. :)
controller (computer usually) -> [optional] controller board -> driver (power source for motors, be it steppers, or servos) -> Motors
wow i was trying to find stuff like that for 2 days now thank the Lord i found U guys !!!
but i still need the power supply no !?!
for those you need 30 to 48 v maybe?
depends on the drives you get too. some can't take more than 40V before failing
and all three drawing 21amps
his are 10v 7a
and can i trust does http://geckodrives.com/
guys to send me the driver they woun't stillmy money .
oh they are well known
I think that there are some notes on the Gecko site that help with selecting power supplies
in the cnc world
He has a good reputation
im on cnczone.com, you can read about them there also
Rutex is another company that is known as good also
I need to go. Good luck with everything guys.
thank for all danfalck good night to U
one last question (i know i must be testing your patient sorry ...) but before i call it a night i wanna to know if is the gecko that i plug to the pc right
well thanx for all the news stuff and the links wow !! have a good night All
SWPadnos is now known as SWP_Away
anyone wnat some steel? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=135&item=6514407525&rd=1&ssPageName=WDVW
<-- how stupid is this?
* Jymmm wants a nuclear sub... FREE ELECTRICITY
* anonimasu yawns
good morning paul
I'll be back later going to go skiing
* alex_joni wishes to go ski too...
* alex_joni leaves
It would appear that CIA-4 doesn't have it's feed from SF.
SWP_Away is now known as SWPadnos
anonimasu: I thought you were skiing :)
SWPadnos: already been skiing
oh - a short-timer
(not that I ski,but a lot of friends do - all day :) )
the friend I was going to ski with got sick..
that would be a problem
but I dont think he wanted it enough..
if you arent in bed sleeping you can go ski..
as long as you have a rescue team waiting :)
nah it's only a 5 minute drive home
I watched some HSM videos today
it's so damn sweet
yeah - it's a very cool thing
That site I linked to - they had several photos with captions like "22.4 minutes machining time"
they just forgot to mention how big the items in the photo were :)
it's very nice..
I am going to try crank my rapids up to 3000mm/min
(think think) - around 120 IPM - not bad
this machine's pretty small :)
I think I'm going to get 175 IPM from my Bridgeport, but I'm not sure I want the ballscrew spinning that fast.
(or the table moving that fast :) )
if I had more table.. I wouldnt care..
or well real servodrives & vital card..
the limit is how fast emc can crank out pulsess..
and how much the machine will flex..
Well - I don't think I have to worry about machine flex :)
I have a USC for generating step pulses (300K/sec max)
and G320 drives + Baldor 28 in-lb motors
my screws should handle a fair bit of speed..
I am trying to design a manufacturing process and do cost accounting for the inlayed premium line turkey calls
ugh - accounting - I should be doing that
the manufacturer states 100m/min
I would be doing accounting, but I think a part of my brain doesn't want to add up all the CNC-related expenses from last year
(and another part definitely doesn't want my wife to see the total :) )
At least cost accounting isn't so bad
just figuring how much money to make
that is the positive side :)
these veneers are very expensive....$4 per ft sq or more
* anonimasu nods
If I laminate them to the plank 90%+ is waste
But that looks better than having workers glues on shaped pieces
then labor gets you
As far as I can see, most cnc-related processes probably waste 50-75% of the material
I think you need to cast, then finish to reduce the waste
(which of course doesn't work so well for wood)
make cast metal or plastic pieces
in this case it would be the standard 41"x5x .75 plank
then finish off the things that need to be precise
We would swamp the market with low cost stuff
To put things in perspective these inlaid ones would retail for $125 or so
So I have to make em for about $25
they're about 2 inches across, right?
materials are about $3
they are a 3.75x.73 hockey puck shape
Ok - hard to tell scale from theose photos
(turkey heads vary so much :) )
So I am at $17 marking up my workers double
( I pay worker a dollar , I make two)
$17 is in the ball park
is your "dealer cost" $25, or is that your cost target?
That is the cost the customer would pay me for the call
Ah - then $17 is a little high for your cost
MY cost is coming in at about 6
even better - that's doable :)
Well the cnc makes the most money
have you accounted for wear / amortization?
But the rest is people sitting down gluing inly on
SWPadnos: I just allot $100/hr for the machine to run
(as cost or sale?)
Althgough I am cheating big time because I am just pretending the machine "magically appeared"
I mean - do you count the $100/hour as your cost (to be marked up), or the sale price of machine time?
Actually the machine took me over a year full time with $20k for parts
sale price of machine time
Sorry for all the questions, but I'll hopefully be making parts for sale when I get my machine up and running, and I'm curious to hear various methods of accounting for the machine.
I guess I shouldn't feel too bad about adding up my numbers then :)
(I'll be around $6k)
well $100/hr is pretty conservative....makes my account fill up pretty good
$4k/week = $200k/year, full time
we are at 3 minutes 10 sec per part
and get $5.25
so 1/15 hour (accounting for moving the piece), so $6.67 per part
* anonimasu is trying to find out why he's circles are becomming jagged
$99.68 per hour.
I think it's my cam program that generates segments..
or somthing like that..
well - crank up da resolution :)
I need to try that..
I dont think I get jagged edges.. when doing a arc..
did you ever get a chance to see one of the configurators run?
Hey. How you doing today.
anon: that's the old traj planner problem
* SWPadnos is avoiding accounting
les: how do I get rid of it?
I got bit all round.
playing with bees?
or use g2/3
les: does it work reliably?
Finished adding the tk dev stuff.
I am told the stepper version does
So I could compile a kernel
I dont think segmentqueue compiles on my box..
I will be testing the servo version soon
it says it's compiled for another ver of the kernel...
talk to Chris
Also Robin is running it
They say it works fine
hm, I hope somone's here later..
I would like to try it..
16:44 < anonimasu> ah
16:45 < les> Also Robin is running it
16:45 < les> stepper
16:46 < les> They say it works fine
just talking about you
speaking of the devil ;)
you are using segmentqueue with steppers right Robin?
correct. on a test setup anyway
anonimasu: do you get an error?
SWPadnos: I can run make config in /usr/src/linux. Does that help?
and it seems fine
it tells me that it's compiled for a incorrect version of the kernel..
I mean when you compile
oh when I try to run it
no - it doesn't help, but if that works, then you have a program to try the config stuff with
I ran it pretty much 24hrs solid with brief stops to G0 X0 Y0 and it seemed not to lose a step
robin_sz: if you have time later could you help me out with getting it to work?
you have to be careful because the config programs always want to read and write a .config in the current directory
I need to leave a bit for some education on the company
It ran that config in scripts/kconfig/conf arch/i386/Kconfig
anonimasu: I had to have help compiling because I;d forgotten the magic chants, but it was the usual build from cvs source and it "just worked"
hm.. ok :/
what did you type and from what directory?
I'll be back later.
I'm just waiting for the new G2002X to arrive now :)
I'm in /usr/src/linux.
les: seen the G2002X pictures and announcement?
sorry - I shuold have more coffee before answering questions :)
I am costing up the inlayed "premium " turkey call product
you do have to run make config in /usr/src/linux to build the config program
Through to completion?
but then you run the program from within the emc2 directory, after copying to those locations in the instructions
you can just wait until the menu comes up, then exit and don't save
les: rabbit driving and fpga, 16 IO, 4 analogue in, 4 analogue out, 6 axes of stepper, 6 channels of encoder inputs ...
Okay. I think I've got it.
you probably want make menuconfig at least, but that requires ncurses
This config is pure text mode.
Should I go get ncurses?
I think so - it's not that big
get ncurses nurses
Robin: Oh...and waiting for a call from Bruce out in Wash state....he is trying to get me TWO Perske 7.5 kWspindles
Both with bad bearings...but almost free
hey, I just got word that I'll be visiting Washington this time next year
like a couple hundred
having an overseas auction, so we go on tour :)
If I had those spindles I could get a life back
yeah right ;)
Instead of being a machine operator all the time
I've got ncurses base, bin, and term installed.
Looks like I need to adjust the path.
Ok - great
robin_sz: We just need to get you a stay over and a code fest during that visit.
les: you need to palletise the material too, to really build on the machine efficientcy, or you'll just find that it machines thenm quick and you send ages unloading
I think Qt is there as well, but it's just a path issue -I can't remember the order I did things though, so I'm probably wrong about that :)
rayh: yeah, stay over will be easy to arrange
Robin: I wonder if bearing replacement is a big deal...the rebuilders say you must re dynamically balance them
I don't see why
les: me neither... a bearing is a bearing
les: if I was rebuilding spindles, Id tell you that too
and changes in moment of inertia would be vanishingly small
libqt3c102-mt is there.
well - qt3-dev-tools(blahblah).deb is a 1.2M file, but I'm not sure what else would be needed.
you could try apt-get install qt3-dev-tools, and see what it says
on the way.
I burned a CD with my package cache, I'll send that out to you with the BDI-4.18 - hopefully today
Hey thanks a bunch.
no problem (I just have to get out of the house before the post office closes :) )
I know that feeling. Sometimes here it is with snow shoes.
not bad. I think you'll like qconf a lot better - it's much closer to what has been discussed for tilly_config
The great thing about this system (other than getting it to work in the first place) is that there are several user interface programs for it already
I think a little work on libkconfig can add things like float sand such
yes - UI programs to present configuration options
And the user interface to it is variable?
yes: config is text-mode question/answer
menuconfig is text mode menu system
Okay. I get the idea.
gconfig and qconfig are X apps, using either the GTK or QT widgets
We could modify qconfig to meet our special tillie needs and use the same underlying data set.
qconfig doesn't change (except to add the float data type)
except for the outputs - but there can also be a script that takes the output of qconfig as it sits, and convert it to ini format
Got the qt3 tools
see if make xconfig works in your /usr/src/linux dir
Good morning Ray - what are trying to build with qt?
An EMC configuration script using the kbuild kconfig setup that the kernel uses.
How you doing today, Bob.
SWPadnos: Still complains about not having the develop stuff for qt.
I did the Synergy interface in qt so I might be able to help
websys: I forgot that you are a qt guru.
yuo did apt-get install qt3-dev-tools?
and apt-get install libqt3-dev ?
thats how i read that =)
9514kB Those will dribble in over the next couple hours.
If I close out other net stuff.
you need DSL :)
Where ray lives prob satellite is the only way
IP over carrier pigeon :)
IP via smoke signals is more like it
When I was a kid I got a five mile roll of mil surplus wire --
rayh so, where you be in the world?
stop talking - we're using up all his bandwidth :)
U.P. Michigan. Map search for crystal falls MI will get you close enough.
well the edge of the world is only a few miles from his house
Even sat may be to close to the horizon...
T1 at $500-$1500/month
And a 12 mile installation.
at only $1.50/foot
and that would only give him a T-1 connection
what about microwave?
1.544 mbits/s isn't too bad
There is a mega fiber burrial about 12 miles. Just no off/on ramp.
Saw a 2B/s a bit ago.
well - I have wire cutters ...
rayh what about microwave?
gotta fump that 300 baud modem ray
websys d) all the above
I talked with my isp. It is line-of-sight from a little brick building of theirs to a point +50 feet above my house.
well - you've always wanted a windmill ... :)
rayh: Um, how big is your lot =)
[16:30:01] <Jymmm> http://www.ustower.com/
rayh: There ya go.... toss up a tower
You could build the Eifel tower with one leg on each corner of the lot
rayh: If you dont want to go the tower route, you could do a pushup on the roof, but at that height it may sway a bit.
My kid used to do some cleaver stuff with weather balloons and ham gear.
rayh: Hey, how about making a deal with the isp, you toss up a tower and they can use it to rebroadcast out.
no such address is the report from dsl...
Sat is about 55 a month.
I looked over the kconfig file and that seems plain enough.
it's a pretty easy format
How about handling variables with a range of values.
How far are you from a telephone exchange ray?
the neat thing is (once you have a UI program :) ) that in the example, unless you select PPMC as the I/O driver, the config menu for PPMC doesn't appear
* rayh scratches his head trying to remember.
rayh: area code and prefix?
My ISP is also a phone company though not the local one.
I don't know if there is an enum type - that may be have to be done by having a sumbenu with exclusive choices
I believe that their brick building has some exchange ability.
(like parport = 0x378 / 0x278 / 0x3bc )
SBC is is alpha about 12 miles. They manage the fiber their also.
rayh: you have SBC? Is there fiber in your area yet?
I get pretty fast dsl 15000 feet from exchange
les: 15K is about the limit.
funny - DSL was supposed to hve a 7.68Mbps option - I've never seen it
(18k, like ISDN, I thought)
I'm 21K feet out, so my dsl is on fiber.
I'm running the 768K optionDSL here
I'm just waiting for Verizon to get their FTTH offering out of beta - 40Mb/sec
I don't even know how fast I am at the moment
I got spoiled by the 1/2T1 at smithy.
hmm what could I use to test
[16:45:17] <SWPadnos> http://www.2wire.com/
go to speed meter
les : http://www.dslreports.com/tools
At one time Verizon guaranteed "ISDN anywhere" and would install the repeates as required. They dropped that about 2 years ago as DSL took off.
Yeah. In Vermont, there was a special deal giving Adelphia monopoly on cable, with the provision that they have broadband available to everyone in the state within like 3 or 4 years
* rayh kneads bread and the link needs a rest or qt will never arrive.
it's been qround 8 years now, and still no cable for 1/2 the state
ROTFLMAO... (spam) Subject: You need to sonside investing in Homeland Security
1209k down 311k up for me
and I pay $30 / mo for that.
les SBC ?
Alltel...the local telephone company
Oh, yesterday I got my hands on a dead copier and ripped it apart. Shitloads of motors, but only one nema stepper on the whole machine.
les: ah, ok.
I think it's 23 actually
I meant usable for cnc purposes
Check the coil resistance. Best if it is 2 ohms or less.
OH OH OH.. The w3irdest thing...... They used at the best I coudl describe it "cable screw"
It was a ss cable that was coiled with another wire to form a "thread". The weiredest thing I ever saw
actually it was the only plastic gear I saved.
SteveStallings: will do.
I noticed they were offering 4mb ADSL in london for 15 GBP/mo
its 25 for 0.5mb out here in the sticks
robin_sz: sucks when they do that.
It's pretty funny that it's easier to get high speed internet in Japan or South Korea (the world leader) than in the western world
.jp really? I'm surprised they have such a good wired infastructure
you can get 100mbit in Japan for around the same as we pay for DSL ($30-$50/mo)
Oh he left... if I'm not around someone tell rayh to check out wireless (celluar) data services. Soemtimes they have flat rate for data alone.
it's only 128, but better than 56K.
some of them are offering 512K
if he can get a cell signal at his his house...
Trying to buy stuff with paypal
never used it
hope it is reliable
les: define reliable?
they do a good job of that.
ordering ten foot sheets of veneer
how in the world is that shipped?
what thickness veneer?
les: coiled =)
would need about 1 ft radius to coil
hmm shipping an empty box mostly I guess
les: 2" coil
fits in a blueprint tube
oh the other way
les: can you say "presto logs"
10 foot tube?
2' tube 3" diamtere
rayh is screwed.... not even celluar coverage out there (except alltel)
I have gotten many things from MSC where the package cost more than the contents
les: dont ya hate that!
Ray just has to spring for satellite
just latency though. If he was in the middle of Africa, ok I understand.
Alltel gives you 1200k for $30 and 3000k for $50....so sat at 50 would be ok for him
I think it's real fast
3000k or more
half the $50 could be recovered by removing a phone line perhaps
so total $10 more than dialup?
100 times the speed?
"course he will have to climb up and clean off the snow from the dish every day ;)
CNC Antenna Snow remover
I'd toss a heating element on the antenns
just increase the microwave POWER! :)
duh, why didn't I think of that
Actually my tv dish is a very reliable indicator of hail
Oh yeah... I'm licensed and I CANT do that!
If it goes I know a big storm is coming from the southwest
heh - got to do it as an "experimental device" :)
SWPadnos: Not with that damn FCC-ID number on the box I can't =(
get a Sharpie
more like a sawsall
THEN it'll be experimental =)
well - don't sell them, but you can make modifications to your own unit. (though the power limits are far below what's needed to melt snow)
SWPadnos: only if I'm within my licensed bandplan.
or is public band
That air powered fluidic generator I have to do will kinda be like designing cavity magnetrons
no take that last part back
few mm wavelength
2.45 GHz is unlicensed, but the max power is like 1W, right? (or is that only for spread spectrum?)
SWPadnos: I think < 500mW
well - my microwave oven begs to differ
You know... xfmrs are the only component I REALLY hate dealing with.... They never have any marking on them, I mean come on how hard is it to put a sticker on a xfmr. and two, to buy a bare xfmr will cost a fortune, but you can buy a microwave or battery charger for 1/5 of the cost of the xfmr alone.
and strip it out.
I just use surplus 240/120 stepdowns
run at 120/60
about 60% rating
get a plug-in 220-110 (or 110-220) converter, and use that. It'll be a 2:1 transformer with plenty of VA rating
what he said
I meant in general... 110vac to 12@1a will run ya $8
used at the lower voltage core losses are very low so you get a little more than half
one of these days I'll look at microwave xfmrs, wonder what that would do
60* 1.414-two drops = 84v
110 input to the secondaries
perfect for a 90v servo amp
les the stepdown or microwave?
les: funy that - most people on the CCED list (incorrectly) subtract the diode drops, then multiply by 1.41
they are cheap
not as cheap as microwave
but the 36v is a bit of a problem with them (for servo amps)
60volts * P2P ?
hay rayh - downloads finished?
oh steppers surge, nm.
SWPadnos: gconf is great. I looked at the Kconfig file in emc2 and it works some.
The next question is handling floats and ranges.
I like qconf a bit better - it seems to have better polish
ranges are in there
The the addition of images to help.
Good. I'll mess with it a bit and see what comes up.
help is a text area, it might be possible to make it html-ized
That would do it.
subtracting the drop first is correct
What about formule for things like max vel and period and such.
you have the documentation file referenced in Kconfig, right? (/usr/src/linux/Documentation/kbuild/kconfig-language.txt)
rayh we found a solution for your internet woes.... It'll require the use of 34 gophers, 50 miles of zipcord, and tequilia
No problem with the last of those. Gophers will have to wait for thaw.
rayh: Nah, we fit them with heated dentures
rayh: ok, add to the list 400 lbs of coal
hmm thinking how that works heh
take the coal, gophers, and zipcord and ignoreit....
then sell the tequila and get sat dish?
no no no you can't sell the tequilia, you could sell the gophers though.
sell the tequila, but deliver the coal
Heh, the emergency bottle of tequilia above my desk is slowly evaporating for the last three years =)
