rotary axis are phasing out?
just reading back up about what you said
oh and Howdy ya'll :)
gezr: yeah, I've found no use for my rotary table as I went with a cnc..
oh rotary table, I have a use for you that you may not have ever seen :)
machine axis as follows, Y(to and from you facing machine), Z (normal Z axis, up and down), C rotary table
gezr: new use`?
gezr: that's why I was wondering about a rotary axis..
have you ever seen a rtb machine?
its a monarch design, sick fast
mill square pockets and the works
gezr: I meant that you have less use for a rotary table when you have cnc..
unless you are doing 4 or 5 axis work :)
oh no, the need for one increased dramatically
think about it
im not talking about flat plane work, with the table facing up to Z
couldnt find the video link
I know what you mean..
like that :)
for making gears and such..
but then again, if your making a hole pattern
you have 2 axis drift versus, total error of one table
you see what im saying?
you can even with a fast enough servo on your table, you could turn with it
milling a bowl for example, instead of using a boaring bar, you could use a ball endmill, and just arc it in one axis, while the table rotates underneath
that would almost eleminate any out of roundness from say backlash
or am i just nuts?
either way, you are STILL nuts, but thats another story
HIT, you sank my battleship
oh man, I was aimign for the aircraft carrier!
there are so many advantages to haveing a dividing head, or a rotary table, I can only dream about now
gezr: well, I've found less use for the rotary table since I got a cnc anyway..
the 0,001 deviance in roundness is something I can live with
* Jacky^ confused
i've too much linear tracks
here there is to studying for years..
* Jacky^ sigh
you ruined it
with a bad driver
From what I remember.... There should be a green LED that stays on when power is applied...
and a second when EMC runs
no that's the estop OK
yeah.. the most fun things in electronics projects
make the LED light
after that it's easy
suggestion: Check the +5V rail on the USC
resolution: +5v on the rail
'k... For a minute I thought the PSU might be going in to current overload...
Is the parallel port set for bi-directional data in the BIOS ?
I dont know
want me to check it?
hmm.. thought you were just having smalltalk :D
alex_joni: You got emc2 compiled yet ?
got the kernel source ;)
getting rtai-dev now
err.. didn't get kernel-source
it's not on the ntworld repo
I set the port as ECP
or should I have set it as ECP/EPP
although now the load fail lights up when I pull the power out of the card
silly question: Are you using a good quality parport cable suitable for bi-directional use ?
I've got 2
About the only recourse is to email Jon Elson and demand he joins you on IRC to debug the problem.
* paul_c has reached the limit of knowledge with ppmc hardware.
I've only ever connected to a USC board once, and that was just to prove that BDI-4.2x worked with it..
yeah I'll drop him a mail..
tell Jon about the missing FIND_IO_BASE_ADDRESS symbol & the required fix.
hm, ./univstepdiags bus
should show the board..
I wonder if it's just the port.
it might be...
since it's been used & abused..
but ll drop him a mail about it
there's probably some way to verify if it's the USC..
I think it's strange that the other stuff on it lights up
There is a utility on his website to do that
I'm pretty certain at least one LED should remain on when the USC is powered up.
paul_c: I am not..
it's the estop led and the power fail led.
the estop lights up when you close the estop chain

paul_c: I have some mortar ready.... gonna encase them in theri own bricks
Jymmm: I think so
* anonimasu wonders if it's just the port once again
anonimasu did you email jon yet?

Have any of you tried using SVG for machining by chance?
no, not yet
I am still in the shop.
I have not emailed Jon yet.

gee hope so.
some mounth ago i bought a small motor: http://www.micromed.it/Elettronica/images/mot%20enc%20dig.jpg
is there a way to run it without complex circuits ?
just for testing
it should have internal encoder
4 leads on motors
the motor looks as an alien
I just dropped the mail to jon
* paul_c gets the rcslib java apps running via http
anonimasu: maybe I found: http://www.vincenzov.net/progetti/dualmos.htm
Jacky^ DC brushed motor, runs on 24,36,42 volts
Jacky^ : I have the sales engineer on the phone
that 02.1979 is the date code.... Feb 1979
the long number is the P/N but they had changed to a new PN scheme
He's going to fax me over the datasheet this afternoon, but it's in German.
I (maybe) really found now: http://www.vincenzov.net/progetti/motoredc.htm
Jymmm: i already have this DC motor
i want to try it just for fun ..
I thought yo usaid you bought this morot? ----> http://www.micromed.it/Elettronica/images/mot%20enc%20dig.jpg
it's a toy :)
Jacky^ Ok, that is the mfg I just got off the phone with. They make precision motors
Jacky^ it runs off of runs on 24,36,42 volts
[15:01:10] <Jymmm> Jacky^ : I have the sales engineer on the phone
Jacky^ it runs off of 24,36,42 volts
so, you only need to wires
GND and v+
but there are 4 leads
2 of these should be incremental encoder
Right, one for 24V, another for 36V and a third for 42V
it is NOT a stepper or servo.
Let him fax over the datasheet in a couple hours
i was thinking it was like a servos
no, it's a PURE DC motor
now is clear
but like I said, it's in German
the only diff betwee a normal dc motor and brushed servo are the rotor inertia..
and I don't read/speak German
servos are slightly more optiimzed..
but with a encoder you can use a normal DC motor as a servo..
anonimasu: it should have internal incremental fotoencoder
Jacky^: does it?
or should it?
i suppose on 2 pin, could be possible to read some voltage value
you need a encoder.
does i think
real encoders to use a normal DC motor as servo.
Motore con encoder fotoelettrico incrementale 12V
well too small to be usable in the real works
Motor with photoeletric encoder
i know it's small
i just want to learn an try..
* Jacky^ take the hammer
fight now !
Jymmm: that ok
on the bottom there are other 2 leads
with a capacitor of 100 ns connected
maybe is not a capacitor..
anyway this will be encoder output
Jacky^ you better learn german within an hour
hehe.. sorry ..
i need to translate before reply :s
when maxon is in USA right ?
this motor was probably used in some precision application years ago
Ths office in USA, is 40 minutes from me =)
maxon seem to me have great products
Jacky^ : No Idea, just trying to get you the info you needed is all =)
Jymmm: thanks a lot ;)
Jacky^_ : Just remember... If I ever get to Italy, you have to provide a nice Italian gal, about 20 something and MUTE =)
Jymmm: The Italians don't know what a gallon is...
Jacky^: A US gallon is 3.95l
I've an idea..
gal, chick, woman, girl, female of the species
and an Imperial gallon is 4.5461l
we have, np :))
Jacky^ but remember she HAS to be MUTE, I can't handle all the screaming, hiting and biting are ok though =)
Jymmm: i will do all possible
Jymmm: Earplugs ?
hey Paul... what is the price of petrol in your end of the world.... its Cdn$1.06/l here
paul_c earplugs for an Italian woman?! I don't think so
nearly �1.00 per litre
$3USD/gal for premium
here the girls love a fun
and sometime, credit card :\
* paul_c slaps Jymmm
paul_c: for which ?
paul_c: That was as of yesterday
well 2.99 and 9/10
wait till it hits $5
time to get a moped
a diesel moped ?
here gpl cars can move on weekend
in the bid metropoly
big*, others not

paul_c: nice :) i like this: http://journeytoforever.org/media/h/hatz2.jpg
first time i eard of diesel bikes
usually who buy a bike love a speed..
hell... Diesel Harley....
i've seen, nice
I have been buying diesel for the first time for my new tractor.
If the oil goes away I will just grow diesel fuel!
here the prices in order to maintain the disel are many high ones
I love diesel.... have a 1 ton dodge pickup and a VW bug in diesel
there's a fixed tax for a year
the bug gets about 3 times better mileage!
Well diesel has more specific energy, and the high compression gives much higher carnot efficiency
I like the idea of having oil on both sides of the piston
LawrenceG: why ?
for the long life of motor ?
always wondered how a gas engined survived... piston goes up... cylinder gets oiled... piston goes down, the gas washes off all the lubrication
[23:51:25] <LawrenceG> http://www.amproexports.com/lister-diesel-engines.html
... I would like one of these for a generator
I think the reason is that the majority of petroleum fractions are of gasoline molecular weight
my cousin have a big generator.. 4x4 mt
maybe a new retrofit.... diesel bridgeport
LawrenceG: Running on a Babbage Numerator?
[23:59:16] <LawrenceG> http://www.utterpower.com/listeroi.htm
this guy imports them... lots of interesting reading... kind of heavy for a moped
