hello again, what program can i use to record the animated motion of my 5axis vismach?
from the screen?
I'd search in synaptic for screen recorder
jepler posted the process on his blog

jmkasunich: In respect to threads, what is NS vs UN ? "15/16-16 UN-2A"
NS = national standard, UN = unified
don't know what either actually means, grab machinerys handbook
2A is fit class
yep I was just going to say that
jmkasunich: So, if I bought a tap that said "15/16-16 NS NOS Tin Coated 3 Flute Tap" would it be the right one for "15/16-16 UN-2A" ?
okey dokey, thanks =)
do you really need to hit 2A, or do you just need to make a hole it screws into?
it's for the ballnut on the X axis of the mill, so - uh, I don't know the answer to that question :)
cradek: Sorry, I really dont know what any of the suffixes mean, those are just what they give in the specs
cradek: Is 2A the tightness of the fit of the threads?
a link to jepler's blog info on dtop vid creation http://emergent.unpy.net/01196105360
yes it's a tolerance of pitch diameter
cradek: Is 2A considered tight, loose, avg?
you should get a machinery's handbook, it doesn't matter the year, so you can get an old cheap one
mine's out in the shop :-)
maybe google knows?
I think 2A is pretty middle-of-the-road
brrrr. the shop

damn. it's nearly impossible to stop eating licorice
red or black?
dip it in garlic power, guarnteed to make you stop
hmmm..... garlic licorice ...
SWPadnos: or better yet, dip it in ascorbic acid
licorice the sweetest sugar known
hmmmmm. sour patch licorice ...
SWPadnos: Yep =)
(you foget - I used to work in movie theaters :) )
SWPadnos: Better than "Would you like fries what that?"
"would you like butter on that?"
about the same I think
you people are sick

I found a place in california that sells 10 pair of full extension 20" slides for 42
shipping is then $32
eric_U: ballbearing slide?
for like rack mount gear?
no, heavy duty
drawer slides most likelt
eric_U: how long do you need and how many?
heavy duty drawer slides
I probably need about 6 pair, 21" -- 20" would work
6 pair?! wth
I thought you were making a foam cutter or something.
could do that
eric_U: Why do you think I have the ones I do =)
they kinda accumulate around here
I'd give up some, but not 6 pairs worth =)
did you go ebay?
lista brand cabinets had great slides. made to hold tools in the drawers. was a good ladder.
eric_U: Nope, I went in the trash can at work =)
best place for them
eric_U: Especially in a data center where most ppl throw beand new ones away still sealed in the box
my experience is those are extra
$150 a pair extra
eric_U: Nah, ppl just dont have/order back rails so they cant use them, they order a shelf instead.
Or if they're in a shared cabinet there is no backrails, so they CAN'T use the,.
I have some full extension rack slides, but they aren't ball bearing
Ah, these are, but not for drawers.
some guy in Georgia is paying half the shipping I am, origin is in california

eric_U: trust me, it's supposed to be there, the manual even talks about it
it's at the machine origin - you can bore a hole there for some reason

1/4" end mill, 1/8" deep, 4 ipm, in aluminum
(I've been chickenshit up till now, doing 0.050 or so stepdown)
what kind of cut?
I bet you really need more spindle speed for that
2400 is as fast as it goes
thats only 0.00083 per flute
wonder if you can get roughing mills in smaller sizes
I bet that would help too
I don't think a rougher helps until the depth of cut is more than a couple flutes
and most roughers have flutes about 1/8" or so, IIRC
flutes is the wrong word
the ridges or whatever they are called on a rougher
teeth ( on flute )
a good rougher will help at all depths of cut, but crappy ones do not
yay, max is in one piece and on one parport again
the jaggies (i like that) are ground differently on expensive vs. inexpensive cutters.
they help because they chew little horizontal chunks out
instead of trying to make a cut that's the entire depth
right, that's not at all what i am talking about.
i'm talking about the form of the individual teeth on the cutter
I'm still back thinking about what jmk said about them not helping if there's not much depth
that's what i'm addressing
a crappy rougher has those teeth cut likea thread, and that changes the engagement of the teeth
a good rougher has every one of those teeth ground straight, without any pitch to them, and those work great at small depths
but if the work is only as thick as one jaggie, won't one flute/jaggie do all the work since the other flutes won't even touch it?
or do they overlap quite a bit
there's lots of overlap on good cutters.
one tooth will do more work though.
for really, really tiny depths of cut i could see only one doing any work
if you cut shallower than the cutter had overlap
I bet jmk could cut several times as deep with one though
you have to be careful at that point, because if your cutter has helical teeth it's going to pull out of the collet
endmill holders are a better choice.
and even with straight teeth it sometimes does that
I think he has Tormach stuff
not familiar =(
holders that go in a collet
i will google it
as long as there is a positive locking (not just friction) holding that toolholder in, he will be fine
but if it's a straight collet w/ no lip, there can be issues
tormach is for cnc retrofit of R8 machines, there's nothing to keep them from pulling out
I didn't realize they went in a collet
[03:05:01] <eric_U> http://cgi.ebay.com/Tormach-Tooling-System-for-R8-Quick-Change_W0QQitemZ230221114288QQihZ013QQcategoryZ25295QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
yar, that will pull out
but how big is his machien
my machine is 3/4 HP
and I'm using a 1/4" cutter
I don't think pullout is gonna be an issue
nah, not on 1/4"
heh, something else subroutines are good for
commenting out a block of code you want to skip
I could manage it
just turn it into a sub with O400 sub / O400 endsub
that and playing 4 part harmony
O777 ignore / O777 endignore
well, my part cut MUCH faster with these feeds and speeds
need to do another pass tho
I expected (and got) significant tool deflection
I told the program I was running an oversize tool, so it left some metal
now I need to go back and clean it up
nice to see someone using radius comp a lot
historically I think that's not a well tested area of emc
I need a shop(s) like this: http://www.garagejournal.com/forum/showthread.php?t=2122
I've never seen that much empty space at once
he fills it up later in the thread
we looked at a place that had a 3-car garage, very deep bays, and a full-size upstairs which was a workshop
oh, there was also a house on the property
upstairs workshop seems limited without a crane
on 10 acres, and even affordable. too bad it was (a) outside he high speed internet access shpere and (b) in the middle of a 5-acre "lawn" which would have been better named a swamp
ain't that the way it always is
would have been fine for almost anything not requiring large machiners, which would have fit just fine downstairs
the garage was something like 45 feet deep - just about 3 car lengths
we looked at a house that would have been very nice, but it was sooooo ugly
and it was "over-wide" too - something like 1200-1500 square feet total
well, this one was a raised ranch, which at the time was our least favorite style
I like ranches if done right
and of course what we eventually ended up buying ;)
ranch isn't bad, as long as there's a basement
they don't build them much here in PA
raised ranch = ranch with basement that counts as living space - ie no storage space
walk out basement a must
also, the garage is generally half od the lower level, so you have no ceiling height in the garage
you can keep that
yeah, it's annoying
the BP fits in there, but if I have to replace the drawbar, I'll have to re-tram the head
lots of places charge extra tax if ceiling in basement is higher than 8'
it's 8 feet, but the lower level of a raised ranch isn't considered a basement
basically a split level?
sort of - most raised ranches have a half-down level and a half-up level, with the front door in the middle
the basement isn't quite deep enough to be a basement, and they finish half of it off and call it living space
know the type now
so you build a 1500 SF foundation, put a "second floor" on it, finish off 750 SF in the basement (the other 750 is the garage), and call it a 2300 SF house
(that's basically our house - a little larger than a "normal" RR style)
once my Parkinson's sets in, I'll need a real ranch

every male in my father's family has suffered from parkinson's by the time they reached 80
well, at least 80 is a reasonable age
true, but why give up then?
if you haven't done anything by then, you probably don't deserve to last much longer ;)
of course I'll cahnge my tune when I get to 60 or 70 :)
I'll have to remember that conventional milling deflects the tool toward the work
I've taken another 0.030 off the profile and it hasn't all cleaned up yet
hmmm. I sense an undersize workpiece
I'd like to make wheelchairs, my BIL had a bad experience with his
I allowed 0.020, so I'm not too far under
1/4 long is a pretty floppy endmill
about 1-1/4" flute length
the parts where it was cutting full width were the worst
other than pride will the undersize hurt anything?
that's what _she_ said
hmmm. she never said that to me
didn't want to hurt your feelings
no, it won't hurt anything
I'm stopping at 0.020 under though
about 80% of the perimeter is cleaned up
that means there was 0.040+ deflection in some places
funny thing is the mill sounded happy during the cut
made nice chips, no nasty noises
does the endmill still have both points?
I believe so - now that I'm done milling I can take it out and look
nice and sharo
nice and sharp
deflection doesn't really hurt cutters
how deep was the cut?
interesting that a 1/4" end mill would deflect that much .040?
.040? or .020 a side?
even if it was .020 worth of deflection, thats still ALOT
it is a long flute mill, about 1-1/4 flute length
and some of the deflection was probably machine, not cutter
do any of you use remote desktops and multimonitor? (for windows)
if I want to helical mill a deep hole (many revs), I need one G2 or 3 per rev, right?
G0 straight down
oops, hurt anything?
and yes (arcs)
see the hole milling in useful-subroutines.ngc, I bet it's what you want
I had one written already, just had to find it
I apparently botched the touch-off
that _was_ a nice 1/4" long flute center cutting endmill
and that _was_ a flawless vise
fortunately I don't think I ruined the part
I bet cnc vises are never flawless for long
heh, I was able to resharpen the end mill well enought that it can helical mill a hole
as long as I don't try to ramp too much
that didn't work so well :)

those are really nice guys :)
Never heard of them
they're from austria
maybe you remember a guy called cncuser
who did the puppy CD
alex_joni: you work with DSPs?
I do remember that.. I was wondering if it was the same guy
skunkworks: he used to work with them
maddash: I used to at some point
alex_joni: got a spindle on that mill yet?
fenn: yeah, a small one
alex_joni: how different is a DSP from a uc?
maddash: the instruction set is different
alex_joni: I mean, performance-wise
it's optimized for large amounts of data
maddash: depends what you want to compare
if you take a DSP which has been optimized for voice codecs
alex_joni: I read that a DSP is just a uc with hardware FP
yes .. ish
it's absicly very similar to a uC
alex_joni: you bought the unumax spindle also?
skunkworks: I got it :P
here's a slightly better pic: http://dsplabs.utt.ro/~juve/emc/mycnc/10170329/PICT0004.JPG
alex_joni: what is your work envelope?
XY : 2.75" x 13" (70 mm x 330 mm)
and Z is also roughly 200-300mm

wooooooooot kernel oopsies are gone (126.96.36.199/3.6)
is it possible to redirect all output from scripts/emc and the emc2 subprocesses (milltask,io,motmod, etc) to a file?
(don't ask me how, but it sure is possible :)
emc > file.foo 2>file.foo &
or something like that
you may need to disable the "normal redirections" in scripts/emc
emc 2>&1 > file.foo &
if ! tty -s; then
exec 2>> $DEBUG_FILE
exec >> $PRINT_FILE
or simply redefine $DEBUG_FILE and $PRINT_FILE appropriately
^^ the emc script does this by default, redirecting stdout into the 'print file' and stderr into the 'debug file', which is used to display the error dialog
let me also point out that motmod (and other realtime modules) output cannot go to stdout or stderr, it goes to the kernel message log
unless compiled for sim
maddash: you can dmesg -c, then dmesg > file.foo
then can I get milltask and other userspace friends to print to the same place?
maddash: I'm not sure it's very nice to print to the kernel log
maddash: timings won't be consistent anyways.. (order of the stuff printed might differ from actual happenings..)
"2>&1 > foo" is easier, and scripts/emc deletes DEBUG/PRINTFILES after it terminates
huh, you learn something every day. You can use bash redirections to open tcp connections using the format /dev/tcp/host/port
oh darn, the next paragraph says that it's disabled on debian

Barely... I just returned from a week in the hospital involving major surgery to repair a problem from a previous surgery. :-(
Sitting on the couch with my laptop sitting on my incision with 30 staples in it. -- But, I'm getting better.
ouch.. sorry to hear that
hope you get well soon
So, what can I do for you?
uhmm.. not much :)
there was a german guy around, asking for someone who knows his way around interpreters
so I sugested he should bug you when you're around
basicly he wants a new interp for heidenhain code :)
And what does that look like?
* alex_joni knows nothing about it
And.... aside from him, how many people would like it?
oh, I think there's plenty heidenhain users
Vq^ here might know more about heidenhain then me
I'd be happy to advise though. If you here from him again, he can email me at lerman dash emc at se dash ltd dot com.
* Vq^ wakes up
here -> hear (still under anesthesia)
* quiteBIGeye kicks Vq^ in the nads
Vq^: you had some converter and sample .h code
Vq^: did you scare that you with crap h2iso yesterday?
alex_joni: yep, thought quiteBIGeye is the one who wrote the sample code
Well, that's a long way from a spec, but my guess is that it is doable; but probably not an easy job.
If someone could produce a spec showing the equivalent gcode for each consruct in heidenhain, it might be a reasonable thing to do.
The big issue is whether the canonical Hcode machine is the same as the model that we use. If it is, than it would be a reasonable thing to do (in the sense that I could do it).
if it is a radically different language (and it looks like it is) then it makes sense to point out the "canon" interface, and program a different interpreter to talk to the canon interface
lerman: I think the trickiest thing will be converting programmative stuff (procedures & such) to g-code
If not, then it would not be something I would consider doing.
jepler: that's what I was talking about..
LOOKS LIKE EVERY
LINE STARTS WITH
You can't use the canon interface if the "model" is not the same.
I think canon is basic enough that it represents the basic machine capabilities
that's assuming linear and circular motion are the primitives I guess
that was certainly the intent of canon
cradek: sorry but only linear lines begin with L

<- contains some examples
But then throw in things about constant time and feed speed. And about commands with mixed rotary and linear axes.
Some of those things are (1) not obvious and (2) not the only way things might reasonably be defined.
if you need new kinds of movement that can't be represented in canon, then you'll also find that they can't be executed by motion

well - kitchen
oh... sometime necessary
[19:53:22] <skunkworks> http://www.electronicsam.com/images/house/kitmud.JPG
That hole in the wall is new
that real tile on the floor?
when we built 20 yrs ago we made the kitchen/dining room/living room all one ...
makes it easier to visit while cooking
yes - well - it is ceramic tile
good stuff, cleans up easily ... and always looks nice
that is why we did this. when friends are over - they are always bringing chairs into the kitchen to talk. this way the breakfast bar on the other side of the hole will be nice.
yep! that is why we did ours the way we did.
otherwise the cook is just a slave with no fun

this house is so out of wack
but that is what you get with a turn-of-the-century house that has been moved atleast once.
it is difficult to hold tolerances even on a new house but old ones are always out of square
did you get your new drives tuned?
I'm working on homing right now ... on the X once it all runs then I will do the Y
I'm also going to upgrade from an 80 V supply to 125 so that will change the tuning.
I just got new brushes for the Mazak
I saw that on the list.
It is a real pain to get the old ones out and cleanup the commutator and then install new brushes.
we are going to need brushes for these monsters.. http://www.electronicsam.com/images/KandT/DSC_0242.JPG
access to two of the brushes is almost impossible
8 brushes per servo
easier to take the servo off?
not in my case ... apparently the gear case is filled with oil and not sealed.
going to need a 150v supply for ours. Think we have a transformer though (3 phase)
(could almost rectify 120) :)
skunkworks I used these people http://www.schunkgraphite.com/en/sgt/home
in my case there were slow because of the holidays but the prices are certainly better than going to ... in my case Mazak
Stede George or Melinda Schall are the contact people
I think they are standard brushes.. 1/4 by 9/16 or something like that
... then you may not need custom .... however the grade of graphite is critical for good results
it is inland motor http://www.electronicsam.com/images/KandT/servotag.JPG
buying from inland may be a good deal but I wouldn't bet on it.
when an ADC is described as 8-Bit does the output on the 8 pins come out like BCD? http://www.chipcatalog.com/Datasheet/6F3EE1B54C1A704E43F54325D6A5B1C8.htm
binary most likely
bcd is for us humans
BJ it should be straight binary unless they say bcd
from the lsb to the msb by 2's?
usually sign ..msb .... lsb
or unsigned ... may depend on how you configure
I've printed out the data sheets and will try to understand how it works from that
yep ... you can select 0-10v or +/- 5 ...
unless your signal is very stable ... you need a S/H in front
adc's don't do well when the signal changes during conversion
unless the chip is one of that that has track and hold
did some of this stuff 30+ years ago. .. converted a P-E Atomic Absorbtion to digital
4 KHz a/d ... into a PDP-11
in fact figure 12 on page 6 proposes a S&H circuit using AD582 together with AD570..
it may be easier to find a chip that is track and hold instead ... but S/H works well and has more flexibility
8 bits isn't nearly as touchy as 12 and up
going to go back to shop and try to get something done. .... see ya later
good luck on the a/d
sorry, I had to step away from the computer
jepler: I see the figure 12 and it looks kinda straightforward
seems like one could just get over-size brushes and chop them down to size
as long as the spring and such is the same size
large brushes have copper pigtails

we haven't really decided how we are going to couple it into our machine.
like, are there setscrews pushing on the key? and if so, which direction
I've installed the ubuntu cd. I've configured it with the step tool.... the axes test there works fine. But when I start Axis, there is no movement.... can you help ?
I really don't remember. I would have to take a look at the coupler
joern23: can you jog the axes?
it works only with the config tool... with the axes test option
does emc show movement on the back-plot?
yes on the pc the axes move... but not on the machine
but with the config tool the axes move on the machine fine.
any idea where the problem can be?
joern23: could you post your .ini and .hal files on pastebin.ca for us to see?
i've never used stepconf so i'm not going to be much help
i'm can currently not get the data because the machine is not here.
it is a standart stepconf generatet config
do you think that stepconf is missing some parameters?
in Axis there is a button, "override limits" I can't set this button, so i can not override the limits... can that be a reason for the problem?
no, if a limit switch were tripped emc would give you an error
but it can't until now there are no limit switches installed on the machine
is there any chance of help without posting the ini file? If not, I will post the ini files tomorrow
SWPadnos_ is now known as SWPadnos
In my opinion there is something missing in the config...
tap tap tap... is this thing on?
I ran the stepconf and the only problem I had was I left the e-stop in and it wouldn't run
SWPadnos: I'll take that as a yes =) New irc client, never used it before.
joern23, stepconf seems to work in many cases, so it's hard to tell what the problem is withoug seeing the files
one thing to be sure of - make sure you're loading the correct config when you run EMC
i think that it will load the right files.... but at the moment i'm not able to get at the files....
I don't think the stepconf creates a desktop start icon does it? You might be using an old config there...
I don't know about desktop icons
everytime i start emc ... it asks for a config... then i choose meine-confi
ok, that should be the right one
i don't understand that... with step conf the machine works fine... but under emc the machine won't move... only on the pc
that is pretty strange, but you should realize that stepconf is a separate program that loads a test environment only
when EMC loads, it uses a different set of parameters to start (ones written by stepconf)
but it seems that EMC can communicate with the lpt port. Because the emergency stop button on the machine works fine
ok, that's a good thing :)
there must only be a little problem ;-)
did you have a pin to enable your drive or anything like that?
so what does EMC do (or not do) exactly?
i have a drive with step and direction signal on lpt
on the screen in Axis everything moves .... but only there :-(
well, I think a look at the inni and hal files will be a lot more informative than speculating about what's going on
no i ve only connectet the drives with step and direction ... all other singals are set to not used...
yes i think too...
can i install emc without using a real time kernel?
did you disconnect and reconnect the drives inbetween running stepconf and emc?
I would than install it on my kubuntu system and i would reproduce the config files
... by the way... sorry for my bad englisch..... ;-)
your english is better than mine, I'm not from England either
I'm not form England too... I'm from germany ;-)
But I think writing here in English is a good training.... but the problem is that I will never now if there are mistakes ...
so far so good
in that case we will let you know if you make a mistake LOL
alex_joni:are you running a robot with emc
good night all
jepler:has emc ever been used on a robot yet?
I think you need a space between the : and what you type..
like jlmjvm: Hello
it has run quite a few hexapods.. I think alex knows a guy that is running a puma robot..
thanks skunkworks,never knew i needed a space
here is a test
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-02-11.txt

oh - maybe not.. :)
did that work?
heh - I am running the linuxcnc.org irc client.. It doesn't seem to have highlighting of names
so a 6 axis fanuc robot arm hasnt been done yet?
Not that I am aware of..
dave is back
yep ... with questions ... or is it puzzlement ;-)
uh oh ;)
not making sense so I have to presume I have something set wrong
goes neg and finds home switch
reverses and stops with following error when it comes off switch
if I use HOME_USE_INDEX NO
then it homes coming off the switch
what am I missing
do your encoders have an index?
I can prove with a scope that the index pulse is getting to the interface board ...
I am not going to be much help
did you try a minus sign on your home latch yet ex: HOME_LATCH -.01
yep ... it goes the other way
and I think still does wierd things or never finds the index
I assume that the index pulse is too fast to follow with halmeter and Xindex (that doesn't set and stay set does it)?
i could never make my index work properly either
I suppose I should try to catch it with halscope ... not necessarily easy
dave_1, what hardware are you using for encoder counting?
jlmjvm what motion board?
ok, then it's unlikely that you will be able to see the index pulse - it goes to the motenc and resets that counter (or latches the count or something) - it may never make it into HAL
dave_1: where did you get your servo dynamic drives?
direct from Servo Dynamics .... talk to Lillian
there is a pin for index ...at the motenc level called out in hal ...
dave_1:did you try to slow your latch speed ,HOME_LATCH 0.001
yes I did ... I think I got impatient waiting. 0.01 is pretty slow
it seems a pity to have an index pulse and not use it
yes,would like to get mine working also
jlmjvm: I would talk to jonE about it.. seems to me they had the index working correctly\
I guess I should try to verify that I can see it at the board level
my board is pretty much the same one they used at Galesburg ... and I think they homed on index.
have to check the ini.
yar, made it home, how yall doing?
HOME_USE_INDEX = YES
what home sequence are you using?
HOME_SEQUENCE = 1
^ MAZAK ini
I think I need to go look at the chart ...
I just checked the Mazak demo ini and they don't use the index ...
maybe that is just stale but it is in the current distro that way
says it does on my mazak demo
I just checked it in the cvs - that is where I got it from
[23:06:47] <skunkworks> http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/demo_mazak/demo_mazak.ini
hmmm wonder where I downloaded mine from ?????
skunkworks:doesnt the home sequece number determine the order of homing if you use home all
I think so ...
question about the steper torque emails recently issued, doesnt voltage have a direct impact on the output torque of a stepper?
* skunkworks is reading the homing part of the manual
for the most part.. Voltage gives you higher stop speed - current gives you torque.
* Top speed
oh sweet, ive done rotary broaching in the past
