ex:10000 step pulses per inch,10000 encoder pulses per inch
2000 steps per rev,500 cpr quadrature with index
would that be correct
alex__ is now known as The_Ball
alex_joni: so what's happening?
JymmmEMC: not much
a-l-p-h-a2 is now known as a-l-p-h-a
I'm thinking about mounting a wood router in my gantry to do a bit of plywood routing, can anyone here recommend a particular router/spindle brand for the task ?
a-l-p-h-a2 is now known as a-l-p-h-a
Dallur: I really like the Kress spindles. I just bought a FME800 so I have not tried it that much yet.
[10:59:51] <alex_joni> http://www.kress-elektrik.de/en/products/browse_products.php?categorie=767
slundell/alex: is that input or output power ?
slundell: 1000w is a bit low for input but fine for output :)
slundell: had any issues with lack of power ?
Dallur, im not sure, but i would guess its input power. I have not tried it much yet but you can definitely mill plywood with it.
the kress site says input power
.. if you're not planning on having a 96mm bit or so
slundell: tried any alu cutting ?
I tried a little with a 2mm bit
slundell: and fair results ?
feeds and speeds baby
and.. frame rigidity
you're planning on submersing everything in water so i guess coolant won't be a problem
who you calling a - oh - hi fenn
the plural of laddie, diminutive form of lad
take it how you will
of course, everyone knows that
so i'm getting excited about open source hardware and distributed manufacturing
i wonder if this emc-users thing is going to go anywhere
there's one problem with the concept (though I like the idea)
moving an object does nothing to increase its value
sure it does
those platinum asteroids arent worth much to anyone right now
so unless you have a single location that can perform all needed operations to a thing, you need to spend time and resources moving it around
no, they have a value, but the economics of extracting that value are poor
no it isn't :)
ok, i'll concede your definition for the sake of harmony
economics 101: there are 3 things that do nothing to increase the value of your inventory: 1: counting it 2) moving it, 3) inspecting it (I think)
I'm not sure #3 is correct
they increase your confidence in the quality of the product, or they give you information about how much product to make, or they let you organize your space better, but those things do nothing to increase the actual value of the widgets themselves
an interesting side effect of "a fabber in every home" is that manufactured products suddenly must be made to a much higher level of quality
unless it costs more to fab stuff
i find that hard to imagine though
economies of scale still apply, which I'm not sure to call a benefit or a curse
its hard to beat zero percent profit
even if your competition is using inefficient methods
by some metric or other
ah, the community aspect
well, that would be nice, but I can say from experience that people change when money is involced, and the change is roughly proportional to the amount of money
well, if you make something for yourself to use, you arent making profit on it are you?
sure but there will still be open source
but if you're making something that someone else didn't have the equipment to make, and shipping it to them, and charging a small amount over cost (even if you donate the money), then I think that's a setup for friction
as I said, I like the idea, but I'm not sure the reality will match the theory here
you deserve to be compensated for 1) your time 2) your capital investment
how much money is your (my) time worth?
whatever you say its worth
how fast should the capital investment be paid off
i dont see where you're going with this
(and i think we were talking about different things)
well, nowhere I guess. like I said, I like the idea, but I don't know if it's practical in the long run given what I've seen of human nature
we could be :)
I hope so, actually
i dont think the "hey everyone lets contribute to emc by making stuff" is a terrible idea
but i'm not betting my retirement on it (not that i have any retirement fund)
* lerneaen_hydra hasn't read much except for the last lines
but IMO if the people that order stuff know each other since before, the community bit, then there's not much of a risk of friction, it's first when you get people that you've never met before that make orders that you can get nasyness
yes great point
unfortunately its those outsiders who have most of the money
heh - having us all throw money around is kind of like the way it is now :)
fenn: yes, very true
they're the peeople most likely to act as asses
a lot of it is just volume
well, that should be true, but in my experience, very good friends can turn into raving assholes when money is involved
100 customers and one of them is bound to be an asshole
only 1 in 100?
archivist: lower bound
well, you could have a "whuffie" system :)
assholes are excluded from community participation
whut is a whuffie?
[12:06:52] <fenn> http://en.wikipedia.org/wiki/Whuffie
that sounds good
but look at what happened to ebay
99.999999% positive feedback
yeah - the main problem with almost any system is preventing people from "gaming" it
they should rank people by percentile
yes the bad boyz get some bad feedback and just get a new name
there should also be some automatic rating thrown in - like 100% if you pay within 3 hours, 10% if the seller contacted you more than once between auction end and payment ...
I like paying cash and collecting
I hate it when sellers wait to leave feedback until I've left it for them, and only leave positive if I do the same (even though I usually pay within 5 minutes of auction close)
I still have 100% suprisningly... but I only have 42 feedbacks
got some nice extra bargains
the new feedback system is anonymous which solves a lot of problems
but its not really done well
yes cash and collect is missing from the new feedback
well if i were a seller i'd like the option to leave bad feedback for an unreasonably bitchy customer who nevertheless paid on time
03jepler 07TRUNK * 10emc2/tests/oword/sub.0/ (README expected test.ngc test.sh test.tbl test.var): test based on sf#1772411
sure, but if I leave feedback saying that the item was shipped without protection and is not what was described, well, that should be independent of whether I perform my part of the bargain correctly
hence the whuffie system
if a seller gives everyone bad feedback, their score is weighted less
it has the same problem as a lot of systems (like our justice system) - you can't tell if the rating is true or fair
(justice: you can't really know if testimony is true or not unless you're the one saying it)
the whole marketplace will acquire a reputation, which it cant really tell you
its like, a closed set or something
you cant really know if you're a bitchy customer or if you've just had bad luck
but statistically the bad luck will average out
jymmm do you disagree?
03jepler 07TRUNK * 10emc2/src/emc/rs274ngc/interp_o_word.cc: commit lerman's bugfix for SF#1772411 -- backport candidate
I just woke up
now this is just way too pretty for its own good: http://www.fabathome.org/wiki/index.php?title=Image:IMG_0110.jpg
I had a idea on the feedback.... Both seller and Buyer feedback is hidden until BOTH have submitted.
If either doesn't leave feedback, neither gets any ratings
why would a seller leave you feedback after screwing you over then?
should be an automatic negative against you if you dont leave feedback
They wouldn't know what they got until they left feedback
if they're trying to screw you over they probably know what they're doing
both feedbacks are blind until both are submitted
ok. jymm would you like to buy my 1957 corvair montenegro?
its in mint condition
Here's my $20, ship it
oh, just for you, since you're such a special customer, i'll give you a deal, how's $10k sound
* archivist offers 20.000000001
fenn: FUCK YOU I'm not paying $20,001 in shipping for a $3000 freight cost! you damn rip off artist!
* JymmmEMC leaves (blind feedback)
well i'm definitely not leaving any feedback now
I can guess what it says
Ebay score for fenn (none)
so i guess we'll never know what jymmm's feedback says
fenn: and you won't get a score either.
swpadnos: gonna order my encoders today,what do i need to read them back into emc,besides a second paraport?
that depends on the encoders
jlmjvm: if they are ttl - you can just run them into the port as is.
us digital,single ended
they are ttl
probably just some wire then
jmkasunich_said you need at least 2000 ips
whatever encoders are rated for
gonna get a 500 cpr with index
you can use 500, but you might miss some
jlmjvm: dont use "cpr" because it's ambiguous
could mean counts or cycles
what the us digital web site says
then they're a bunch of fucktards
and a 500 count encoder wont go well with a 200 step stepper
500 counts in quadrature=2000 counts per rev,motor uses 2000 steps per rev
alex_joni: what happened to the newlines? http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2007-06-19.rdf
isnt that right
JymmmEMC: the rdf is always like that
read the .txt
dont the motor steps per rev need to match the encoder counts per rev
google seems to be pulling up the rdf over the text for some reason
jlmjvm, it shouldn't be necessary, but it might be good. then again, it might be better to have the encoder resolution be double that of the steppers
ok, according to us digital CPR means cycles, so yes
500 CPR should gives you 2000 pulses per rev
since you're only using it for following error detection, you probably need a few times the minimum following error you'd like to detect
* fenn shakes his fist at the encoder gods
500 lines should give you 2000 transitions... ;)
* archivist would never expect a micro step to get anywhere near accurate
(so if you want ferror th be <0.001, you need an encoder that gives you resolution ~5 times finer, or <0.0002)
no, microsteps aren't meant to be accurate positionally, they're meant to smooth motor motion
I knoe that
even full steps are dependent on load
although maris says microsteps are very accurite
mariss also sells stepper drivers
they are when he's testing on the bench, but not under load
and "i'm retired" doesnt count when the damn things sell for $150
fenn: they are on sale this month ;)
yeah i heard
he doesn't give a shit if you buy one - he sells something like 2000 a week into industry :)
the 500 cpr should work good then,positionally would be .0001
I need to get the engraver on ebay with a link to them saying - 'it would be a good time to convert this to cnc' ;)
that's a reasonable resolution to use on a servo as well
skunkworks: your selling it?
cant wait to start homing to an index,will have the most accurate on the block
yes - I really need a 'paid for' garage more than a engraver at the moment.
jlmjvm: why are you so concerned with homing accuracy?
i want it bulletproof
the two phases of an encoder may not be that accurate
skunkworks: is it accurate?
JymmmEMC: it is 4 threads per inch (2 start)
jlmjvm, dont confuse resolution with accuracy
dont want a chip on switch changing my home position,also want ferror so software will stop if a motor stalls
skunkworks: For the $200 you spent, you'll never be able to regain that again down the road. Plus you could start selling dog/cat/ tags or PCB's if nothing else.
JymmmEMC: so full steps would be .00125 and z is .0025
you could buy 3 geckos and still undercut the competition
skunkworks: Shit, it can make you money abiet slowly, but still
JymmmEMC: I would rather have a small machining center.
skunkworks: fuck, you could take it to the flea market and setup a booth if you wanted
what is that - teach am man to fish....
gather round folks, its a machine from the future! look on in awe as the intelligent automaton does its technological magic
custom graphics engraving, not just this run of the mill text only crap
Give a man a fish and you'll feed him for a day. Tell him to go get his own damn fish and he'll either learn to fish or die of starvation. Either way he won't bother you again.
skunkworks: what you want for it then?
the truth comes out
I am putting it on ebay - let the market price it. looks like it will probably go for over 2K if I am lucky
fenn: Hey, if he's gonna gonna shoot himself in the foot, I'll still want the gun
bite the hand that doesn't feed you
skunkworks: well is it up there yet?
No - I still have to fix a few things.
I did get the stepper drive working last night. open diode in the voltage reference for the current limit.
that is why it smoked the enable mosfet. running full current to the stepping motor
(it looks like it had been fixed.. Crappy solder joints on the stepper l297,298 ic's

you could get it for 1500 right now..
well - if no one bids I guess.
300lbs, never realized it was that heavy
$2500 for an engraver?
maybe not so flea market portable
isn't that a bit excessive?
seems excessive to me, but so does everything
it is a nice machine - all cast aluminum
lerneaen_hydra: manual machiens go for $500
spring loaded lead screws
excluding the stencils
the $2000 seems excessive for steppers, drives, and crappy old software
then again, cnc is still relatively exotic
at least in the eyes of the common man
* skunkworks wouldn't pay that much :)
* skunkworks is wondering if he would get more buying 3 of the cheap gecko drives and setting it up with mach..
"optional deluxe package" add $500
It is all modular - I could make it so you could run it with the original control - or plug in the geckos.
fenn: you know about this DIY machine tool? ( sorry its a yoohoo group ) http://groups.yahoo.com/group/multimachine/
they bolt together engine heads to get perp bores for spindle and over arm. and get bport sized machines pretty cheap.
yes i've seen it
i think the gingery machines would work better and be easier to build
as stiff as the head casting?
i thiught that was its good point
best way to do it would be to make a horizontal mill out of concrete with metal inserts, then bore out the headstock to fit tapered roller bearings
then the spindle is guaranteed to be parallel to your ways
yesterday someone linked to a concrete machine, bridge style. with bolt on rails.. no details on spindle bore tho. could bore the headstock using the nailed on rails maybe
yeah looked pretty neat
it's a gantry though, so it didnt really have a headstock like a horizontal mill or a lathe would
er, bridge i mean
i mean it's the same topology more or less, but the proportions are wrong

hey its that kress router
[13:40:03] <fenn> http://www.kress-elektrik.de/en/products/browse_products.php?categorie=767
Eeeesh, so much running around (shoulda expected it from DOD though)
hehe "Snacka om kick ass fräs!"
the kress pdf is listed under recessing and shaping machine ( fras is mill )
it looked like he had a kress router in the cad drawing on the first page
[13:46:42] <fenn> http://i177.photobucket.com/albums/w231/Spruft/29liten.jpg
<- front and center
i just thought it was funny because they were talking about kress routers earlier
cant read the logo
I thought that was pretty cool.
yeah, rebar and sackrete
I think the only few things I would have changed was - j-hooks for the threaded rods and chicken wire frame added to the rebar.

03jepler 07v2_1_branch * 10emc2/debian/changelog: bump version number and note bug fixed
the aluminum "platforms" just dont look so rigid
better to shim something directly against the concrete
or bed it in epoxy or something
its what i did with my lathe.. 1 sec
[13:56:07] <fenn> http://fenn.freeshell.org/lathe_pedestal.jpg
the squares are "tee nuts" and the lines are threaded rod
I still think it will be 1000 times more rigid than a mdf/steel frame router people make.
i built a 4x8 mdf/steel router
then when i put it all together i just threw it away...
nice lathe.. so the base is the only thing concrete - and you mounted steel on top of that?
well, the lathe bed is aluminum with a steel plate on top as the way surface
i took the aluminum casting to a machine shop because i didnt have a reference straightedge
so that became my reference surface
nice - My granfather had made a shaper and horizontal mill from plans - I will see if I can get some pitures of them. he used them a lot
this shows the general construction theme: http://fenn.freeshell.org/cross_slide_compound.jpg
i milled those surfaces flat on a drill press :)
then scraped them in
nice. father had done a lot of stuff like that before he had big iron.
oh, milled with a fly cutter made from a piece of carbide stuck in an aluminum sprue, which i turned down on the drill press :D
fenn: nice, is the 1st pic steel 'way' , aluminum plate, then concrete ( top to bottom ) ?
but the "aluminum plate" is more of a 2"x2" ribbed box
ah. you casting guys.... ;)
if i did the lathe over i would use rectangular steel tubing
casting something like that is just silly
i still use this trick all the time: http://fenn.freeshell.org/toolpost_carbide.jpg

i wonder why nobody's used emc to squirt neat patterns of goo out of a syringe
fenn: SHOW ME THE GOO BUTTON!
the self-repli-pooping machine ?
look at the barrels they replicate and imagine the fit of the plunger
i like the idea of casting/squirting slabs of wax, then machining the wax to a nice surface finish, then casting stuff in it
you could cast plaster and ceramic too, not just polymers
machine tool casting material http://www.zanite.com/industry.html
or investment casting, but, not sure i'd trust a robot with molten metal in my basement
yeah that stuff's kinda expensive
gotta go, bbl
we have epoxy dispencing machings to put a domed surface on decals.
hm $0.75/lb isnt as bad as i remember
would not work for3d modeling.. :P the epoxy doesn't dry that fast.
neither does the goo

yes, I think it would have been :)
too bad so few people can figure out how to use gpg

Hi alex. ready for the weekend?
alex_joni: how do you search thru the logger archives?
or what is a good way to search
I use grep
but you need a ssh account for that :)
heh - for users that don't have shell accounts, the google site search on linuxcnc.org also searches through the IRC archives
I set up some cgi-script on my own server, while the logger was there
but I'm feeling a bit funny about putting it on DH
I'm worried about exploits & such
and putting something like this on a shared server .. is a big no-no
I have tried using the site search on google and never seem to find what I am looking for
crap - I can't get to linuxcnc at the moment
yah - it just went down
dreamhoststatus is down too
insert snide hosting remark here.
it's better than sourceforge
oh wait- maybe not :)
it seems that some dns is down
but dhstatus finally gave me a wordpress error
hehe big hosting failures seems to be carching at the moment

(my dad - not my grandpa)
is he still around? your grandpa?
No - he just died last month. (hence all the pictures - they need to take care of the estate)
sorry to hear that
He lived a good life. His body just finally gave out. he was 91
that's a nice age

What type of machine do you run with EMC? Vote once for each machine
... You already voted for this poll today!
cradek: trying to cheat .. eh?
no, trying to vote once for each machine like it says
* cradek grumbles about web polls
* alex_joni thinks cradek grumbles too much :P
sorry, I'm faced with doing something with windows at work, it makes me all grumbly
tell me about it
I got two new workstations at work, which means moving around 2 more
so about 4 fresh installs + programs
03alex_joni 07TRUNK * 10emc2/src/emc/nml_intf/canon.hh: fix some comments about number of axes, move IO related CANON calls to the proper place
wow, every time you run something from the start menu on winders xp, it shuffles the entries around for you to make it harder to find that program again
I wonder what genius thought of that
cradek: actually it sorts the by usage count
after a couple of days it stabilizes
but sometimes it tries to be smart.. which is just plain wrong ;)
like exchanging similar programs (if you have 2 programs simialarly named in the same dir, or one that gets executed with a different param)
i use a boss bridgeport
jlmjvm: sorry to hear that, I do too :-)
yeah, saw your complaints.. yuck
cradek:you dont like your bridgeport?
i'd prefer a 500 dollar jig borer and an old K&T or Cinci vertial mill
it's a great machine but the control is very flaky
over a bridgeport
oh, a cnc bridgeport, ignore me
you still got the boss control
yes for now...
me too,running mach for the moment
NOoooo not mach... ;)
already have emc2 working,just havent totally switched over yet
its scary sometimes
jlmjvm: we would all like to hear your impressions
jlmjvm: what is?
are you saying it may not be an industrial strength control?
basically dont like windows in the picture
oh, mach is scary..
yes mach,not emc
emc is industrial strength
jlmjvm: glad you feel that way
I still think there are some bits & pieces to bend into place before it's a real industrial control
just took me a couple years to get here
join the club.. I am naming my first born emc
but it's way better than when I started
skunkworks: hope you're kidding
im totally impressed so far
i just want dependabilityfor day to day use
i did learn enough about basic motion control from mach to move to this level
a nubie gotta start somewhere
usually that is with turbocnc..
or with me - writing your own.. (that sucked)
skunkworks: I can relate
although I have some motion control code that still works in industry :P
but it's 1-axis
easy to write..
skunkworks: didnt you show me a breakout board pic yesterday
that was cool
gotta build me a board
[21:14:28] <skunkworks> http://www.electronicsam.com/images/KandT/servostart/breakout.JPG
there should be filter capasitors on it - but other than that - it works grea.
my new g203v gecko will only work running straight from the paraport
odd. (I have some parker drives hooked directly to the printer port - they work great)
if i run it thru my breakout board i get signal noise
jlmjvm: a scope would be good
and somebody that could read it
jlmjvm: and a digital camera
and a place to put pictures online :)
it works great hooked direct to paraport
this isn't a laptop by any chance?
wanna make a board that passes straight thru for the geckos
I really like the breakout board from pmdx
for an industrial grade machine ;)
and then pullups or whatever for my limit switches
it's not quite cheap
I love cnc machines..
but it has a chargepump, and relays, etc
I really do :)
i looked at them yesterday
[21:20:14] <alex_joni> http://www.pmdx.com/PMDX-131/index.html
I machined a shaft to thread today at the mill :)
i think the 203v needs to be hooked direct
only way i can make it work
jlmjvm: might want to ask mariss about it
he's very helpfull/friendly
there is no reason why - but as others have said - it has more sensitive optos - so more issues with noise
does a pulldown help?
hes how i knew to wire it direct
jlmjvm: what does it do again?
thru the breakout boards
skunkworks: wanders off
runs by itself?
when he switches spindle on/off
(manual switch) -> extra pulses
will pulse the motor when you turn on spindle or coolant pump,and they dont come thru board
maybe the board sucks..
i think it does,or is damaged
or you need a pulldown on the optos..
but works perfect wit g201
to kill stray noise..
<- is not a EE
but, that might help
I ran my plasma with G201, and never had a problem with runaway axes on arc start..
this board has no optos
no, but the geckos..
err the geckos do have optos on the input
yes,can they be filtered
[21:25:29] <jlmjvm> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=33&products_id=45&osCsid=6d1d4b0260b8c77faab5284014875208
thats the board i have
. All inputs are outputs are tied to pull-down resistors. Pins are never in the air open to noise. If you leave a pin in the air you will get a LOW or 0. If you input a ground you will get a LOW and a +3.3 or+ 5 vdc signal will deliver a HI.
you should probably put a pull down on the input pin..
to the board..
i have a few resistors here
I dont know :/
how bout a nice 470k
[21:29:19] <jlmjvm> http://www.winfordeng.com/products/brk25_parallel.php
sorry, I have no idea :/
thinking bout 1 of these
you dont need buffered outputs for the gecko.. :)
should be able to run gecko strait thru
but what you need is isolated ones for the power stuff opto > ULNXXXXX to a relay or something
I think more like 10k..
cant i do that with the winford
wire drives direct,and add pull ups,or downs and optos for the inputs
and outputs that would run relays
but you end up wiring it yourself..
wanna learn,want a burly breakout board
want something that will work for me and my machine
did you look at that winford
who has what kinda board in here
I have no idea
Ihave several that are similar, but not for a parallel port
that board is no better tahn a wire, except that it's probably going to be a bit more reliable and easy to disconnect/reconnect due to the screw terminals
you can do something equivalent by cutting a 25-pin cable and connecting the wires to a barrier strip
right now i have a cable i cut,pulled 3 wires out for g203,reconnected the rest
never heard of a barrier strip
I'm sure you've seen them though :)

plugs into my breakout board and my 203v,ugly but works
well, that's a definite plus :)
the winford boards are pretty inexpensive, so you may as well get them, if you don't want any protection for your parallel port
they have a pass thru board also that you can insert components,couldnt you put optos in that

i ran my mill all nite for the last 2 nites
worked perfect with the ugly cable
at some point, you may as well just buy an isolated parport card, like the ones from PMDX or others
and/or fix the cnc4pc card :)
im gonna fix it with a hammer soon,lol
i like the looks of the pmdx
the 1 with 1 relay would be good for me
what kinda board you got swpadnos
O don't have anything that's meant for the parallel port :)
could you build a super breakout board
I could, but at the moment I have a lot of paying work to do :)
has anyone here built one of those rapid prototyping bots
those look kind of neat, especially for wax deposition
rapid prototyping bots?
you mean like reprap?
yeah, like that
any of them
* anonimasu has only seen them
those could have some serious implications for anyone who wants to really, really build a machine tool from scratch, as in lost wax casting the machine base and components
i never really gave it much consideration until a couple days ago
hows this scenario,gonna have to have 2 ports for extra inputs for my encoders,use a winford on port 2 for gecko outputs and ttl encoder inputs,then something like a pmdx on port 1 for every thing else
isolation for things that need it,and direct connection for things that need it

steves_logging: i have a question for you
he's logging .. not really here
is he the pmdx guy
yeah, but his nick needs to change to steve_stallings for him to be here
often he'll see later what you type to him
jlmjvm: best to ask away, and check for an answer later
just wanted to know if he had a board compatible with the g203v
website says not supported yet
who has info on the pluto_step
and skunkworks has one afaik
good night all
cant find a website for it
good night alex
SWPadnos: Strike 1 =(
SWPadnos: Tell me about it.
I can't - you haven't told me about it :)
