* LawrenceG learning about KstreamRipper.... VEEERRRYYY Interesting
is that a dvd ripper?
Hi Jymmm ... it saves audio streams from internet radio stations
ah, ok. I personally couldn't see a reason for doing that. Unless it was internet talk radio.
list of stations at www.shoutcast.com
Yeah, I've wanted to setup a jukebox for a long time. Just no time to do it =)
I ripped all my cd's onto the computer and listen to them while in here... random play is much more interesting than changing albums allday
it looks like a 128kb/s audio stream eats about 35k bytes/sec of download bandwidth (10% of cable connection)
the cool thing is you can fit about 2000 songs on a dvd and the newer dvd players will understand mp3 music disks
It was a bummer when Napster got closed down... I got exposed to a lot of new music that one never hears on the radio
nice when one can listen to a song and either drag it to the trash can or keep it for future listening
it was a great way to find new artists and buy their cd's
well... got to run off to bed.... eyes are slamming shut
it's still night here for a few more minutes
Jymmm: read earlier about lithium grease
err your question
any comments anonimasu?
if I remember it right there are particles in lithium grease..
or well particles/thick/
The deed has been done. Got a multipurpose lithium grease
ah well, there are better grease for that kind of app :)
is it for the ways?
the rails, ya.
and the ballscrew too
I use some machine oil for my machine
See, they only had HUGE grease guns, or one type of smaller gun. The ***ONLY*** grease cartridge available for the smaller gun was lithium
how's the machine?
unless I wanted to pack the gun by hand.
it's sad, very very sad.
are you experiencing tyhe learning curve?
As I got the cartridge in the grease gun, I find that I didnt have enough clearance to get the gun tip on the zirk fitting.
one zirk fitting came out
have you cut anything?
the Z axis is binding
at the top 2" still
the edge if the Z axis pulley ground itself againest the frame because they didn't mount it far enough away
I hope I can get work done today so I can play withthe USC
the T-Nut for the X motor mount stripped out becasue they only used screws that went in 1/8"
the project I am working on will be up for testing
and to replace this t nut I have to disassembly the 80/20 frame
which was aligned using a flat table are parallel bars.
I have a DVD ready to play... need to relax a bit. chat at ya later.
DVD? this time in the morning?
Yeah, been a pretty stressful day.
ok, mine has just begun
need to unwind
it's almost midnight here
Jymmm: I am building a system for controlling gearchanges at a racecar ;)
anonimasu: If you REALLY want to impress me.... Build a system for controlling dumbasses.
Jymmm: I haev no wish to impress you.
the only thing I wish for is more sleep.
Jymmm: 320v pots a end to dumbasses..
you just zap them and they end up all nice..
i guess 320V could control them...
I wish for a zap key..

anyone know how much feedrate can I get using PERIOD = 0.000020 ?
is it possible to calculate it ?
your maximum theoretical step rate is half of 1/PERIOD
since the signal can only change once per period, and it takes two changes to make a step
hi cradek , I changed PS using a new transformerm 34 V, it go much better now
but i cant go up to 50 IPM, getting following error
I suspect max pulses reached ..
i think ballscrews are small :(
cradek: 1/0.000020 = 50.000/2 = 25.000 is it right ?
what are 25.000, khz ?

I am still trying to find out about emc tool change
emc1 or emc2?
found a nice HSD spindle with ATC
I know there is something there
I wonder if I need a separate plc
I know there is some code .. but I'm not sure there is much in the ways of logic and IO for it
well if I could just get M06 to talk to an external plc that would be fine
has to send the tool number of course
and wait for tool change complete
need what....three or four bits?
and get back a "yeah I did it"
and a "no, failed "
or "oops, that slot is empty"
well this hsd is new in box....5 Hp, power drawbar.....$900
$4700 from distributor
I told the seller I prob would.
but I need an inverter
he also has an HSD inverter, but 3 phase in only
I would rather not have to run it from the big rotary converter
Some will run from single phase
but must be derated perhaps
I will call some sales reps and find out
its more a question of will the motor rewire
HSD can tell me
5hp is mid sized, it probably will
let me show you the unit
[18:55:06] <les> http://cgi.ebay.com/HSD-ES915-Electrospindle_W0QQitemZ7540422799QQcategoryZ92081QQssPageNameZWD1VQQrdZ1QQcmdZViewItem
looks good huh?
private email he says it's new in box
ceramic ball bearings
iso 30 taper
buy it dude, before someone else does
We are just playing tel tag
all I need is a not doa promise and i'll take it.
That picture is from man web site
just need to make sure it wasn't in a flood, etc
"new in box" ...
says it all really.
new in box that was underwater?
les LOL I was JUST gonna say that
that guy lives below sea level really
les : Well, just check for kelp =)
seen his other adv
I think he called once and I missed it...

State of the art PC based CNC Controller with Linux CNC operating systems
Yeah I want to talk to that guy for sure
He is on the road this week he said
seems to be an emc guy
so why would he give away that spindle?
what makes you think that?
just the copy in that add
mentioning rs274d makes me think that
and the linux cnc comment
what else could it be
possibly .. but there are other linux based CNC apckages out there
closed source ones?
well could be
could be some embedded thing
yeah he mentions integrated cam
ah, no says pc based
I didn't see that
could be weber systems I guess
you'll find out soon enough
I would buy his VFD too but HSD says 3 phase only for input
hey .. you shoudl see the funny stepper drives we found ...
oh . yeah
so ... 5V stepper ...
bag of darlingtons
and a 5v supply
on, off ...
there is a deluxe version that give 20% more torque ..
uses mosfets, so you dont lose 1 v across the darlington
I was on Skype with Yuga this morning talking drives etc
He really wants a 2x3 meter machine
they guy claims no load speeds of anything up to 120rpm ...
We discussed the ramifications of that
I bet he want 300mm ox z axis too
well I finally said ok....you have lots of time and money right?
so hes looking at rack and pinion, big ballscrews servos the size of logs
I almost would suggest one of the Chinese machines...but a big risk
I told him rack on x, ballscrew y and z
possibly rack on Y ...
Concerning his budget...sent him to Hiwin and andantex
that is about 2/3 of the cost right there
rack is a non-trivial engineering task
did you ever cost up some andantex rack units?
bet they are thousands
we have some cheap rack guys here
hardened anti backlash?
I said cheap
good enough for a router
well the soft steel racks etc are plenty cheap
wouldn't live long though
fit em up, weld em on :)
if the pinion at least were hardened....
they usually are
might live a few hundred hours I would guess
or till first crash
couple mm high soft rack tooth driving couple hundred kG....
even a minor crash would bend those teeth
oh well I told him to buy andantex anyway...so no problem.
Damn I wish I could find where the tool change code is
im not sure there is a lot ...
theres lots of tool compensartion code
and stuff to stop the machine and let you change it by hand
prob have to write some stuff in a cannonical function
communication to a plc is a problem
I looked and there is nothing
and out of io too
must send out the tool number
dont *think* it does
parport is used up
as is stg dig io
could send an analog sig out to a window comparator
if it was anywwhere .l it would be in bridgeporttool.cc
looks like a lot of the logic is done
but still needs the "move over here, do this" stuff
theres stuff like:
ioStatus.tool.toolInSpindle = 0;
yeah I see it
but no comms
in reallity, you'd want that to come from some external tool detector switch Iguess
so ... *some* of the logic is there
you need that and a routine to go to where the carosel or holder is
but its going to need fleshing out and some IO
and ... logic for handling aborts
and "try that again"
might be worth it for me if I score that spindle
remember...turkey call= 24 manual tool changes a day for me
you know, with wrenches
I mean spanners heh
it is not good.
Heck even using the power draw bar without a carousel would be a big improvement huh?
...while I work out an ATC
getting too much to do....air electricity generator, paint robot, now atc
but if I don't up that throughput turkey call and air generator project will conflict
I want to do both
I WILL do both
you *could write it into the gcode
yeah I was thinking about that
pretty poor way of doin git
but you might have problems getting it done otherwise
like T6 is always followed by a motion routine to go where that tool is
my view is that "M06 T2" shoudl be all it needs
retracts the spindle, moves the gantry
does whatever it is that it does
but a find replace thing WOULD work as a kluge
others think that anyting that moves the machien without the interpreter knowing about it is bad and wrong
persoanlly, I'd just stick it in a toolchange macro
so different machine could implement whatver macro they needed to do the business
but you'll find some umm, hostility, to motion calls from macros
well one way or another it can be done
need confirm tool locked and unlocked comms
one io would be enough for that
steal one of the lesser used parport bits?
or add another port
easier in emc2 I think
hmm apart from the motion
used a limit switch to operate a plc to check status...estop if failed
seen the USB io exapnder from US DIgital?
and nice IO pins ... as in IO
in or out 32 bits
I am running the adsl modem/router now from usb
ethernet got fried
thats HARD to do
I think it is not as good
in the storms?
the other router EXPLODED!
you need lightning arrestors
I lost some modems that way ...
relay was kinda "open plan"
literally blew up MOVs
and got to the mb through ethernet and poped the on board stuff
but otherwise mb is ok
get a lightning arrestor ... mine was 100 GBP, but not had trouble since
lost a modem every 6 months beofre that
I will do that....It was a freak thing...but happens every few years
virtually everyone in town here lost their tv
fot long sparks/plasma coming out of the mains outlets

2) they are *proud* of their moonshine stills out there
aw all the moonshiners now make meth
i make beer

we dont have rabies in the UK
do rabbits get rabid (or rabbid)
they get myxy

like once every 20 years
well, I had better get to work. I am 6 days behind due to the storm
No internet= out of business
foot long plasmas?

WAY too big for what I needed
it's 35 V capacitors
ok for 32 V ps ?
FAR too big ...
sold it to a guy setting up a body shop ...
it will keep him warm in winter
I need more air...about 5 kW at least
for the shop?
I am throwing a lot of money back into the business
get a hydorvane

ill be back
If I just buy tools I can resist airplanes and girly Audis
and .. speaking of which
I must go do soem work
earn some $$$
les : Here ya go.... http://www.fu-fme.com/
I bought 24V transformer, now steppers are working better
i need to change capacitors of PS
do you think 35 V capacitors are ok for 32 V ?
Personally, I wouldn't. More is always better.
50 V could be better ..
an other good roule of thumb with power supplys is current rating , if you need say 2A from it use a 4A psu ,
AchiestDragon: i've not much experience about :(
I bought a transformer 220V - 24 V 200 VA
ok, this just bugs me in general... When in the hell have someone said "Power Supply Unit", you say "Power Supply". it's PS damnit, not PSU!!!
my motors are 2A/phase i think is enough..
AchiestDragon not directly targeted at you, just everything I see 'PSU' in email/forum/etc it bugs the crap out of me =)
psu is the proper abbreviation for it
When have you EVER actually spoke the words "Power Supply Unit" ?
24v on a 200va psu is about 8a
8000 uF capacitors should also be ok
i will use small capacitors
* Jymmm can tell that Jacky^ didn't read the whitepaper.
so if you got 2a phase then 6a total , usualy you dont drive 3 phases at once unless your half stepping , then you got 12A total :(
instead of big capacitors
Jymmm: not yet (at all) i'm tryng to translate and understand :\
Jacky^ ah, ok.
small capacitors should be more 'fast' on peak current
for what I know ..
the rtansformer you have should do , would recomend dubblining it if the machine is going to be in almost constant use
or the transformer is goning to get hot and will cook the insulation if on 24/7
if using the machine for say 2 to 3hrs at a time then should be ok with the one you have
it should no suffer , first, because is oversized
second, also have heat sink with fan up
i was reading in whitepapers, in some case an additional capacitor 470 uF is used on drivers
the problem you may have if half stepping (driving 2 phazes at the same time per stepper ) and running in all 3 axis at the same time is that the motors get less power than otherwise
2 phase at the same time ? of the same motor ??
it sound to me strange ..
anyway i'm using half winding motors
4 phase steppers sequence one then the next etc , when half stepping you leave the last one on and power the next so it moves half way between the two so half a step
how much axis emc can use ?
for 6 axis need to use 2 parport right ?
there are 12 bits on a parallel port
of course you then need the other parallel port for things like home switches
i know pin 2-8 are used now ..
sorry.. no ..
I want to build a small arm using 6 small steppers, just for fun
some ULN ic should enough maybe ..
you still need somethign to interpret the step/dir
you could do phase outputs but that would take two full parports for 6 axes
ok, i've 3 parports(2 isa 1 pci)
surplus cards but are working fine
then phase outputs will be simplest
it will help me to learn more
I want to try something like an arm that write with a pencil ..
it will be hard, but funny :)
sounds like complicated kinematics
something like this: http://www.sorgonet.com/robotics/sicario/
but i don't like this project
it doesnt use Linux, and are a little expensive..
i want to try with small steppers, just for fun
also, the sicario project use DC motors.. if I understand well

Here information on Epson stepper motors
I messured the phase current thru the coils of serveral epson stepper motors. Used a small ressistor to mesure max and min currents thru a coil.
Re: Here information on Epson stepper motors
plz tell me about the ratings of the stepper motor like torque, input voltage and the current.
how is possible to measure current of stepper ?
sorry, was on another channel
be more clear with the question
do you mean "how is it possible to measure the actual current"
do you mean "how is it possible to measure the rated current"
