cradek: are you ?
already seen this ?: http://vinvin.dyndns.org/projects/scanner.html
seem very simle
no, but I've wondered about doing this before
I'm looking for a good project
what cad program u ppl use?
no linux based one's?
cradek : DOS?! I though i was the only one that still used DOS
I run autocad on freedos in qemu on linux
it's just more convenient that way. I don't have any problem with using dos when it's appropriate
qemu is a virtual machine (free)
so there isnt realy a good linux program out there?
cradek replacing dosemu I suppose?
Jymmm: dosemu isn't a virtual machine, it's a program that tries to provide dos services well enough to run dos programs
totally different programs
qemu is more like vmware, but free of course
ioh, it can do 2k too
I tried latest snhapshot of qemu. I can see it's hard..
at least installing win2k
ok, so pull out the dual G4, toss on linux, then qemu and xp =)
I have installed win2k once successfully
it won't accept update and service pack
no 3d support..
(I'm not a windows user)
I'm too ..
I just tried fo fun
a good solution should be vmware, but .. commercial
latest vmware + vmtools work fine
Yuga: which apps should you run ?
i dont have a clue... trying to find out what the emc chap's run
wanna download a dbi install and put it on one of my machine's just 2 c how the program work's and all
i am very new at this and trying to do asmuch research as possible
Jacky^ / cradek u's have a cnc machine?
right way, i agree with you
Yuga: the mine it's a very expensive machine
professional I mean..
hehe... cnc drill press?
take a look: http://www.roboitalia.com/modules.php?name=coppermine&file=displayimage&album=random&cat=&pos=-676
* Yuga has this problem... i hate doing anything small
total price $ 60
and the shit thing is that i dont realy know anything :)
Jacky^: what does the table slide on?
but i changed the dremel in the pic with a 600 w router
cradek: the X table
Jacky^: yes are they drawer slides?
how much play does a pinion/rack system have?
I don't know how this is called in english :\
I have to go; goodnight everyone
Yuga: i started 3 mounth ago
but i made from myself anything
inexpensive cnc, hw controller, etc..
very funny ;)
well i wanna build a big machine
I learned many things
no point in doing it twice :)
what program's u use?
BDI 4.20 linux
the gui is not so important..
all are working fine for me
yes.. but gui's are always nice :)
how easy was it to get it all working off bdi?
but I'm a linux user since 2001..
well i am new :)
I don't know how much experience you have with linux
have used it... but never realy been that successfull
It for me worked at the first time e without install , directly from live cd
You just need to learn how to setup correctly the ini file, nothing more..
and how difficult was it to get it to runn with your cnc machine?
before to get my machine working with gcode and file (with the right axes setting) i spent some week..
before I just manually move the axes
pushing a button :)
cool... what steppers u using?
you can take the advantage of understand well english (I'm not)
read the handbook on the website
is very useful
[21:53:31] <Jacky^> http://www.micromed.it/Elettronica/stepper.htm
I bough 3 stepper for E. 30
first need to download the bdi install... problem is that i dont think i have enough bandwidth left this month
like this: http://www.micromed.it/Elettronica/images/C018.jpg
and they cost u how much?
E. 10 anyone ($10)
it's a very nice price in this website
yep... the problem is that i am looking for realy big steppers :)
if the stepper is big, then also the driver will big..
yep... buying those gecko drives
I think gecko drivers should be fine
but the problem is to find a big stepper now
not that many big one's around
will be expensive too..
ya... willing to pay for them thou
just need to find the buggers
how much ampere should have the motor ?
you know ?
not a clue
just looking for some big one's
I suppose mor of 4 ..
give me a sec... will find the one's i was looking at
[22:00:26] <Yuga> http://www.campbelldesigns.com/stepper-motors.php
<--- the one at the very bottom
was looking for a bigger one thou. that one's 6 amps
6 ampere per phase
should be very strong :)
yes... but i am trying to make one hell of a big cnc machine :)
so ya... i need big motor's
i should probibly go for servo's. it just seem's that i need alot bigger budget then
servo's should be better than stepper
I live in Italy and..
I don't know where you are
yes... but i dont fully understand how servo's work. so it makes it alot harder
i am from south africa
if in UK or US, there are meny peoples here
south africa = little shit hole :)
where to buy from there..
so ya... all the info i have is off the net
i am going to have to import them from the us or australia
I think also Japan could be a good option
or Taiwan maybe..
ya... but difficult to find japanees sites
know of anny?
but I think the price's there would be much better :)
they would be... but to find them :P
some one kill me.
A-L-P-H-A : Can't, probably on the no-fly list!
A-L-P-H-A Hey! tha'ts what you can do.... goto the airport and yell 'gihad' and bob
looks like I have to visit the US in a couple of weeks
I'm sure someone will kill you
robin_sz Good to know, I'll contact TSA on your behalf =)
Tennessee Savings Association?
robin_sz: No, the dumbass mother fuckers at the airport that think EVERYONE is a terrorist... even the 6mo old babies
[22:27:02] <Jymmm> http://www.tsa.gov/public/
A-L-P-H-A why, what happened?
robin_sz : where to ?
ummm, new york
is it cold there ?
Ah, never been there.
I thnk its in the north
in the films, it always has snow piled up in the streets
yeah, in the winter time.
* robin_sz boggles at the TSA site
you know, the terrorists have already won
gawd damn fucking patriot act! should have NEVER happened (the end does not justify the means)
but its the Patriot act ...
That is one thing I could go to jail for.
if you dont like it you must be un-patriotic ...
not a joking matter.
whenever the wankers over here want to get through someting, they call it like "the criminal justice bill"
but they didn't get chased across town for photography either.
you'll notice that in the UK we are just getting on as normal
although I did here there were some more bombs today.
I'm just venting. If I really got into the conversation I'd probably need a self induced defibulator.
What you think.... 0-60VDC @ 0-13A linear PS for $150 ?
what you want that for?
probably a very poor choice for running a machine from
well, running a machinw was my first choice (lab being 2nd).
well, not a good choice really
becasue it's regulated?
whats wrong with a transformers and a capacitor huh?
finding a XMFR is difficult... not a lot of electrical surplus in the area.
how many amps do you need
the other thing I figured is it being variable I can adjust as needed down the orad.
I'm thinking abotu getting some geckos
how many amps do you need?
at least 4
and how many volts?
well, whats the rating of your motors?
[22:59:52] <Jymmm> http://www.xylotex.com/StepperMotor.htm
* 20 = 63.28
so a 60V supply is about right
60V @ 4A = 250Va
48V xfmr * 1.4 == 67.2V
try a 35V
gives about 57V
see, evening finding 12,24,48V @4A is difficult
is it bollocks
well 12V is easy
digikey, mousser ...
oh, just expensive
If I spend say $70 on a xfmr + caps + misc hardware I'm almost at the $150 range of this PS which is ready to go and I can adj the voltage lower if needed
that was my thinking.
by $70 I mean with tax ans shipping
If I could find a couple XFMR's locally for $20/ea and wire them series/parallel, that's another story
mine cost about 20 GBP (35USD) from Farnell
but the last few I wound myself :)
Now... If I had the time and a clue in winding microwave xfrm's.... now were talking!!!
microwave txfrms? the high voltage single ended tings?
they don't even have them in the spares catalogues anymore
Yep, taking out the secondary adn wind my own (someone on here already did that)
I think Phydbleep is the one the rewind them
well, I would just buy a toroid for about 20 dollars and stop worrying
well, I got mine from farnell
heh.... iso xfmr and a variac!
you ordered that?
can't find the isolation xfmr big enough
huh? Autotransformers provide the most cost effective solution for voltage conversion when electrical isolation is not required
well, isolation txfmrs are generally either 1500VA or 3300VA
either would be big enough
no, I mean why doesn't a autotransformer provide isolation?
because it only has one winding
OH! no secondary
so cant be used with geckos
I never knew that.
well, err, thats the difference between a normal txfmr and an auto transformer
Yeah, I understand now. I just never realize what a "AUTOtransformer" really was.
auto as in self
I talked to a XMFR mfg up norht a long time ago, just found them again!
very nice folks
will make a xfmr to your specs
I must admit, I'm confused
:) lots of new faces around here !
last time here was feb 22
where you has been ?
real bizzy in the construction
i almost vergotten how to write englisch
machine construction ?
ah ! well.. my english is bad
yours too ?
home's and so one
i'm from holland
i'm in Italy
at first experience with emc
in the beginning hard time but works great
are you a developer ?
I mean working around emc ?
nope i triet for a while but can't get it done
I'm not too
too few time :\
too much to learn
just download and play with plasma cutting
plasma ? cool
yeah making my own sprockets
the mine is a toy-machine.. lol
just for fun
Jacky seen Paul lately !!
