Then we wouldn't have too choose between having too many "extra" choices, and having a wanted choice be unavailable. (Or messing with configs, yuk.)
oops, "have too choose" = have to choose
OK, I'll quit flooding now, LOL
is there a symbol for an alternate action pushbutton? ( aka push-push on-on )
the mechanical thingy, not a flop
for what kind of drawing?
any, i'll make an Orcad symbol if i can see it
is it a swx contact with 2 arrows underneath?
haha, telegraph key
I didnt' see a knife switch
i found eaton (cutler hammer) bt the symbols dont infer the toggl action at all
I've never seen a mechanical monostable switch from one of those type companies
ya know you shoud be able to mentally animate the thingy if its a reasonable representation
it's always been companies like oak
[01:32:48] <tomp> http://delta.octopart.com/Eaton_W103W2.pdf
googling oak pushbutton is a swamp of non pushbuttons
for some reason i get access denied
I couldn't think of a pushbutton manufacturer, sorry
cutler hammer makes industrial pushbuttons, the monostable ones are more consumer level
? start conveyor, stop conveyor without plc ( or chance of plc error , hardwired like estops )
but there has to be an ansi or mil standard symbol for such a thing, how do you design an airplane?
cutler hammer/AB would probably want you to do that with relays
limit switch has a symbol
closest I found was "Positive opening, latching with twist to reset"
IEC 617 symbol for E-stop is fun
ok, its like a knife swx, but (i imagine) it means the arm is shorting the left or right sets of contacts http://imagebin.ca/view/plES2h.html
it >looks< like a knofe swx
I'm not buyin' that as the correct switch
irc showed me nada
iec ( damnit tiny kbd)
has to be an IEC symbol for that
Back in 1 hour+ (time for "24")
24 is evil
too many people think it's real
ah! its the lever ont top og the shorting bar and a ghost lever laning other way (so sayeth the IEC )
on top of
(note to self dont buy another eeepc )
oops thats ansi, iec has a wiggly bit on the mechanicl link on actuator to shorting bar
ic code SA
I thought about going downstairs and looking for my ansi drafting book, but I was too lazy
np thjanks for the hints
[02:16:47] <tomp> http://info.bannersalesforce.com/xpedio/groups/public/documents/literature/ms_t8_s3_e.pdf
one page pf of ansi and iec symbos for power
I saw that, which one is your switch?
should have given you that link
SA in iec speak, SS in ansi
i read your mind :)
eric_unterhausen: what makes you think '24' isn;t real?
not to get into that discussion on here
I'm back from "24". It's not that people think it's real, it's that people think it's relevant to reality. But since discussion of "24" is off-topic, discussion of "24" will continue in #emc-24. All are welcome.
sometimes hitting paste is a really bad idea
Is SWPadnos in DC writing speeches?
Since I am a slow typist who types long answers, #emc-24 is now closed, LOL. But you never know, it might come around again.
my understanding is that archivist convinced you to design a usb to stepper drive device, so get to work
Is that for me? I recall only the recent here-reported post (from what, cnczone?) where several people had a lot of fun lampooning a "that should be easy" assertion by someone. It was very funny.
KimK: ok, that was too easy
archivist said there is a synchronous mode that might work if anyone could figure it out
Interesting. I'll place my future bets on RTnet, though. Is there a length limit on USB2 ?
I thought regular mode has (x)k blocks, where x is something I would never be able to remember more than a few minutes
Oh, I didn't specify. I meant cable length limit.
that one I know
Yeah, there's another drawback. 17(?) feet isn't long enough for some machines.
it certainly is for the class of machines that would probably use it
300 feet, on the other hand...
Yeah, that's a good point, all tabletop steppers. Yeah, might work.
OK, *you* get to work on it right away, LOL
yeah, I'll get right on that
actually, any time I'm tempted to do something like that, I realize a pc with a parport is cheaper than anything I could hang off of a usb port
this has been obvious for at least the last 10 years
I hope someday to mess around with a parallel port and steppers configuration, just for fun, even without a machine to put it on. I'd just like to get a little more familiar with the config that most people are using with EMC2. But, first things first.
it's a blast
I scored some cheap drivers from ebay, it's well worth it for the amusment factor
what does the 'teach-in.py' script do? I saw it in the axis/scripts folder
the comments aren't clear
looks like it writes machine movement to a file
maybe for robot teaching?
that might be it
jog to a spot, hit a button to say "here is a spot on the toolpath", jog to next, hit button again, etc
that's what I was hoping it was. thanks
I saw some guys doing that on an aircraft wing, I was thinking that was a job one step up from a qtip tester
I too have a set (2? 3?) of NOS stepper drivers. I don't think they microstep, though. Half-step, probably. Finer? Not sure, don't recall. I have no parallel port device though. I should get them out.
half step is better, if you have 4, you can play music in harmony
eric_unterhausen: you wouldn't happen to be the EricJ who added the intel D945GCLF2 board to the latency test results on the wiki?
don't think so
was it recent?
jan 9 and 11
I'm curious about the test conditions, etc
I just ordered one of those
nice small board, 6.75" square
I thought about testing this computer, but I'm not going to use it for emc
$100 with CPU, 512M ram, and shipping
although the board seems to be available about everywhere, for between $85 and $90
it's an atom
CPU is included with the board
I was wondering if they would work with rtai
a guy from EDN magazine reviewed and tested several mini-ITX boards (not for RT) in the latest issue, that one did quite well
I have some robots I'd like to put one in, beats mounting laptops
funny, someone mentioned emc2 on one of the atom reviews

"LAN must be disable to install ubuntu 8.04"
that seems odd
I wonder about the driver issue
sounds like user error
because the live cd doesn't have all the drivers built
somebody was whining about that on here a month ago
several other reviewers report success with stock 8.04
so its either user error, or we left off a driver or two
pretty sure it's the latter
argh, I'm flunking algebra here
intersection of the line x = m*(y-h) and circle x^2 = r^2 - y^2
square both sides of the line equation, so it is x^2 = blah
set the two equations equal to each other and solve for y
its a quadratic in y, use quadratic formula, get wrong answer
two wrong answers
I know which answer I want, so I only evaluate one
are you sure the equations match your line and circle?
the line is a ray coming out of the camera lens towards the mirror
the circle is the mirror
the coordinate system is centered on the mirror
h is the distance between mirror and camera
I'm about 99% sure the equations match my line and circle
I'm 100% sure that my calculated intersection doesn't work,
I plugged the calculated Y back into both equations, they x's don't match
not even close
so I did something wrong in the "set the two equations for x^2 equal to each other and solve for y" step
but I've re-done it twice, and verified that the code matches my algebra
-b +/- sqrt(b^2-4ac) / 2a is the quadratic formula
not -b +/- sqrt(b^2-4ac) / 4ac
and now I will stop working it out
yep, works much better now
my daughter's algebra problems kicked my behind
one of the problems could be done with trig, but she hasn't had trig yet :)

what is in english "material smoothing-out" ?
preparing material for making parts
roughing is removing lots of material before finishing
what does google translation say
squaring is getting the material square
or is it the fettling one does to a casting
and if related to straightening sheet for laser , rolling
I think the best is fettling
thats knocking/grinding off sprues etc
I've never even heard of it :)
helps to read old books BigJohnT :)
I've never heard of it either, and dictionary.com was not much help. "To remove sand from a casting"(?)

KimK, I did my bit a few years back, went to Dayton, Chicago,South Bend and Detroit
Very good, I hope you enjoyed your stay (or travels)?
Sounds like a tour of manufacturing centers? You said a few years ago, so I assume you got to see them while they were still operating? ;)
Cam accros for the Dayton hamvention, the rest was touring around holiday
I never made it to the Hamvention, kind of quit following it. Has attendance dwindled over the years?
archivist afternoon, might you know a decant source of timing pulleys and belts over here?
it was 15 years ago and only went once, dunno how it is these days
pjm_, a few
BigJohnT hi, re my testing from y/day with the velocity mode on the pendant, it seems to work nicely, when u stop turning the handle the machine stops, it dont cache or buffer any of the steps
pjm_, did you manage to get that network analyser
pjm_: how did you change to velocity mode (I can't remember) :/
BigJohnT one sec i'll check the config file
setp encoder.0.x4-mode 0 changed to setp encoder.0.x4-mode 1 in the hal file
archivist no the guy had gotten rid of it
ok, I'll ad that to the wiki site thanks
pjm_, shame :(
archivist yeah its typical init... oh well... so re the timing pulleys i'm basically looking to replace my v-belt drive and DC motor with a 3phase job, and i want to ensure nothing can move hence needing a toothed belt
HPC in chesterfield, Daval down south somewhere, some local trade stockist have the drive stuff like that
how do check my step time and step space ? (sherline stepper motor)
I would use an oscilloscope
but what do you mean by check
in stepconf i have http://imagebin.ca/view/7xCNlTEV.html
pjm_: I've updated the manual and the wiki site
ah excellent, nice one!
yeah the velocity mode seems good also
been looking online and i seen where steptime is 500 and step space is 5000 . was wondering if i am wrong or they had a typo
piasdom, yours is set very slow
Can you use halscope?
well, i removed the sherline controller card and made its' own box and get it a separate power supply
getting a 512 video card today/tomorrow and want to do see it all is ok now
KinK:how do i get to halscope ?
one moment... or anybody else jump right in if you know
it is on the Machine menu
this is a basic setting up problem, speeds and latency
piasdom: step time and step space can be backwards if your pin is set up different from what the controller is looking for
I have the answer, here it is: "Complete operating instructions should be located here eventually. "
if your controller is looking for a high for 500 and a low for 5000 and you have the pin set the other way around...
hang on, there's another place to look, brb
archvist:that is what i'm trying to fix...my latency
BigJohnT; that is not my stepconf..it's one i found on the web mine is at http://imagebin.ca/view/7xCNlTEV.html
i have 500 for both
OK, this is better. "halcmd: loadusr halscope"
i got the scope...but i get "realtime function not linked"
KimK : thanks
piasdom: what are you trying to see on the scope?
don't know what the scope shows...trying to see what my step time and step space is
BigJohnT : i separted the sherline controller card from my computer to fix my latency trouble
piasdom, whatever you set on your numbers
archvist : so i set the values ? i don't set them to the motor ?
and why don't my halscope work :( ?
you dont need halsope to fix latency
archvist : then i'm looking in the wrong places
i'll start over...thenks
one more ? ...does it matter if i use a wireless mouse or cabled ?
[12:52:57] <BigJohnT> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?FixingSMIIssues
should not matter AFAIK
piasdom: is your latency so high that you can not get the speed you want from your steppers?
BigJohnT : i saw that but i looked in my file ...it doesn't show any smi .so i thought i didn'y use it
in what file
i am talking about my rtai.conf file
piasdom: is your latency so high that you can not get the speed you want from your steppers?
BigJohnT : i get the realtime error
BigJohnT : and ya'll said it was my latency
so i was trying to fix that
ok, and then you raise up the number until you quit getting the realtime error
The Latency test result number
BigJohnT : which ? time/space ?
neither of those
on the basic machine info page the Latency test result number
last time i did a lat it was 27384(run all weekend) but that is before i removed the controller card
ok set the number to 30000
i want to get the video card installed then i'll run lat .get the card today/tomorrow
BigJohnT : but while i'm waiting...i wanted to see if all my stepconf was correct to my machine
so i was looking at time/soace
what kind of driver do you have?
for what ?
for your steppers
the controller card ?
* archivist assumes the bog standard sherline
this has been updated http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Stepper_Drive_Timing
BigJohnT : can i use that model ?... i have model 5400
I don't know if they are the same
i'll call sherline ...but they won't help me...i'll try
test and tell us
btw could someone point me in the direction on how to get emc2 to see other file extensions by default, not just ngc's
archvist : i'll do that
archivist: So standard Sherline means no special controller card, just parallel port connections?
if your numbers are higher than you need it will work fine
got to be something there between the parallel port and the steppers
i'll let ya'll know ... brb
KimK, I have no idea
piasdom: if you put those numbers in and it does not work then invert the step pins and try again
BigJohnT : K
archivist: OK, I was just trying to follow along. I'm unfamiliar with the basic parallel port and stepper setup that many (most?) are using
past time for me to head out guys so talk to you later
OK BigJohnT thanks
KimK, Im using stepper but not got close to a sherline
Oops too slow
What are you using? Building your own?
Machine, I mean
me , home brew 4 axis at the moment, 5 when I finish a trunnion
So your spindle remains vertical? That's probably best in most cases, I'd guess.
toalllistening : the values don't move the mill
BigjohnT : you said to invert the step pins ... the directions for all three axis ?
It doesn't move at all now? And it did before?
Sorry, piasdom, BigJohnT said goodnight. We'll try to help if we can.
KimK : correct ,i'm trying a few things to fix my latency
KimK : didn't see him go
KimK : to answer your question eariler sherline has a controller card off the printer port
OK. So there is something beyond just the parallel port, then. And you don't have a second copy of the card to trade off for testing, do you?
KimK : no sorry... wish i did
would me glad trade off
piasdom: wat are you using for the sherline configs? There are some tested ones in the cvs.
[13:46:50] <skunkworks_> http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/Sherline3Axis/
[13:46:58] <skunkworks_> http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/Sherline4Axis/
on the m5i20 are the pull-ups and the pin-49 VCC both the same voltage? I'm trying to figure out how best to run an SSR from the 5i20 for spindle on/off control. The presence of those pull-ups makes me think that I need to have VCC ---|>--- Mesa Output Pin so that the SSR turns on when the mesa output is low.
skunkworks:thanks...i'll try that and let ya'll know
BigJohnTatWork is now known as BigJohnT
jepler: from the 5i20 manual: The power connection on the I/O connectors can supply either 3.3V or 5V power... When W1, W2 or W3 are in the left position, 5V power is supplied to the connector and associated pullup resistors. When W1, W2, or W3 are in the right position, 3.3V is supplied. Does that help?
jepler: Also, doesn't the 5i20 have driver functions to invert the output state if needed?
5i20 manual again: Note that even though the 5I20s FPGA can tolerate 5V signal inputs, its outputs will not swing to 5V. The outputs are push pull CMOS outputs that will drive to the output supply rail of 3.3V. This is sufficient for TTL compatibility but may cause problems with some types of loads.
For example when driving an LED that has its anode connected to 5V, the 3.3V high level may not completely turn the LED off. To avoid this problem, either drive loads that are ground referred, Use 3.3V as the VCC for VCC referred loads, or tristate the output signals when no drive is desired (open drain).
in the grand tradition of electrical engineering, I would steal my circuit from Anders Wallin's board that he designed for the m5i20
skunkworks : this is my current stepconf http://imagebin.ca/view/BaYTYsiV.html
.... loading the one you suggested ..brb
KimK: aha, I missed that "and". That addresses my concern, I think
skunkworks : and i get this error with the suggested file http://paste.org/index.php?id=4914
jepler: OK. Also, the 5i20 is supposed to be Opto-22 compatible, so I was going to pull up an Opto-22 (board/module) data sheet and an Opto-22 (stand-alone SSR) data sheet and see how they compare. I downloaded a bunch and now I'm having trouble finding them
piasdom: Could not open command file 'core_stepper.hal'
you need to copy that file there
(sounds like an unconfigured emc2 though)
alex_joni : i just replaced my mill.ini with the web fersion...guess that's not how s works :)
alex_joni: i didn't have the core_stepper file in my emc2 folder abd did copy it there .....got this error now http://paste.org/index.php?id=4915
alex_joni: after running stepconf
emc/iotask/ioControl.cc 792: can't load tool table.
Could not open command file 'core_stepper.hal'
hm, looks like two problems
cradek: i didn't change the tool table
if you're using stepconf, why are you moving around hal files? stepconf generates a full working configuration.
cradek: skunkworks_ suggested piasdom use the new sherline configurations
they don't have the "common files"
cradek: was try different conf before i get my new video card in so i can have all correct before installing card
can i just copy the core_stepper file to emc folder and try that ?
I'll stop "helping"
cradek: i appreciate ANy "help" i get .....thanks
piasdom: short answer is "yes". you can also look in /etc/emc2/sample-configs/common for these files.
piasdom: (I think that's the right path)
jepler:saw that after searching thanks
piasdom: just a guess, but the ones you need may be: emc.nml, emc.var, tool.tbl, core_stepper.hal
jepler: i have all those file in emc folder
now i get http://paste.org/index.php?id=4916
sigh, no good deed goes unpunished
the link skunkworks_ gave you is for the development version of the inifiles, and they're not quite compatible with 2.2
Use this link to download instead: http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/Sherline3Axis/?only_with_tag=v2_2_branch
emc quits because it can't load the tool table?
eric_unterhausen: I think the fatal error is this one, further down: #
core_stepper.hal:6: Ini variable not found.
core_stepper.hal:6: Ini variable not found.
core_stepper.hal:6: Ini variable not found.
is the stuff on pastbin an output from emc?
or a system log?
a combination of both
doesn't look like dmesg
eris_unterhausen : it's an error msg when i start emc
a win pops up
I've never seen it before
jepler: same error msg
try this one, then: http://emergent.unpy.net/files/sandbox/Sherline3Axis.zip
it should include all the necessary files, and I tested that it starts on my 2.2
jepler: i copied the extracted file to my emc folder and got the same error...should i have done something else ?
hhe, I just looked over the specs of the motors i'm using again,.. max. axial force: 10N
that's....... not impressive
jepler: i noticed it doesn't have a mill.ini file ...is it still using my old conf ?
in the ini chooser you'd pick "Sherline3Axis_inch.ini" under "Sherline3Axis"
after unzipping that file in your ~/emc2/configs directory
i'm starting to think emc is not look at the file i'm working on
when i go to choose the file, it doesn't see any ini files and i see them in file browser
when I unzip that file in the right location, here's what I see when starting emc2 with the config selector: http://emergent.unpy.net/files/sandbox/config-selector.png
when i go to get the file, i can only see ~/emc2/configs/my-mill/my-mill.stepconf
that means you didn't unzip in the right place
or you chose the wrong options when unzipping
ok...i'm in the wrong place...brb trying again
I unzipped in the terminal, like this:
$ cd ~/emc2/configs
$ unzip ~/Desktop_/Sherline3Axis.zip
i was in stepconf.....it works :)
toall : thanks
I swear 20" monitors aren't as big as they used to be
but you can't sneeze at $130 for a 20" monitor either way
why can't i see other ini files in stepconf, can only see ~emc2/configs/my-mill.stepconf .. i can see ini files in file browser ?
you can only edit the ones you created
or you need the .stepconf file or whatever the extension is
BigJohnT: thanks, i like to use stepconf(getting use to it) ,but i'm getting familar with editing the ini file also
d### it, i need to slow down..almost started a latency test with emc running
don't think that works
remember you add things in the custom.hal file and it will not overwrite it when you run stepconf again...
i haven't started editing custom.hal yet, one pebble at a time :)
can giving the controller card a separate power supply(straight out the wall) help with the latency ?
and other issues
just getting off the video portof the motherboard ?
video and and power management issues on the motherboard
I hope the system I just stopped using as my main desktop has good latency. My new desktop seems to have very good latency, but I'm not using that for emc
when i go to open a file, is there a way to get it to start looking in a different folder ?
I assume he means the file open dialog
* archivist assumes more than one dialog method
* eric_unterhausen assumes he meant in emc2
did you try ../ ?
emc2 ...open dialog mehod...to start to run a file
there isn't a browse option, don't have it installed on this computer.
piasdom, clear questions describing what you are doing in which program
i use file,open...buit it starts in ~home/emc2/comfig
nobody uses mini :)
buit = but
i heard that before
where are your files?
guess i'll have to look around...thanks
dir i made for my file,it gets backed-up from there
axis has the same habit, its just a few clicks to get a file
it is a setting in the ini file
alright..then that's what i'll have to do
~ means /home/currentuser
so the default looks a little strange to me
maybe I should check out mini, I have a little touch screen for my mill that I'd like to use
or maybe it would be better to tweak axis. Didn't I see reference to vb skins in the next release?
PROGRAM_PREFIX = ../../nc_files/
skunkworks : i saw(and changed) that, but it didn't work - for me
probably because they aren't in ../../nc_files
piasdom: I take it you're a linux newbie
eric_unterhausen: very new
somewhere on the rt-linux mailing list archives, I asked the stupidest question ever
I'm still proud of that even a decade later
i don't think there're stupid questions, just stupid who don't want to learn
it's annoying at first, then you start to learn the shortcuts and standard locations
then it becomes annoying again when you change distributions
i learn by trial and error, lots of errors
I thought there was a "my computer" icon in ubuntu, but it isn't on my computer
I read that is - back out 2 directories and go down to nc_files.
all I'm saying is that he doesn't have a nc_files directory two levels down
shunkworks: that's what i do and will continue to do .thanks
. isn't where we think it is
shouldnt the PROGRAM_PREFIX be an absolute path?
~ is an absolute path, but it's malformed in his case
i'll try again
well, it would help if we knew where your files were
i have this in the ini file /home/father/emc2/nc_files
but my file are in ~emc2/gcodes
go to the dir where your gcode files are, run "pwd", and set PROGRAM_PREFIX to that?
open a konsole and tell us what it says when you type pwd
my file are in /home/itt/gcode
i just used ~ for /home/itt....
/home/itt/gcode is the same as ~/gcode
thought there was a misinderstanding
are they in ~/emc2/gcode ?
i'll set it to that
I guess there is always some chance mini screws with the path
it worked ..
don't know what i did before
jepler: the new conf you gave me improved my latency so far
nm...only been two hours
i'm home sick as a dog.. and bored outa my wits.. anyone heard any good news??
im back... sound system went to crap hard....

[Global Notice] Hi all, it would appear one of our sponsors are having some issues with their connectivity. As a result we've lost one of our client (leaf) servers along with services. We hope to have things back to normal asap.
[Global Notice] Hi all, Everything is back to normal now (services included) -- bgp issues with uunet as the cause of the problem. Apologies for the inconvenience and have a good day.
How do I set up my home to be in the top right corner? If I use stepconf to set a table travel on the x to be 0 - 210, then set the home location to be 210, then it goes left when I home it
if I set it to zero, it goes left
if I set it to -210, it goes left
shrdlu: it you let it go to it's "home", what number do you have ? (new here,but will try)
shrdlu-: "If the machine moves the wrong direction at the beginning of the homing procedure, negate the value of Home Search Velocity."
(under heading Home Search Velocity in http://linuxcnc.org/docs/html/config_stepconf.html#sub:Axis-Configuration
Good evening. I have studing one solution for create one comunication for EMC at Labview of Nation Instruments.The problem is read ad write Halui.Exist one librari for read and write parameter for EMC
oh, that worked, thank you jepler
motioncontrol: If you want to use a new kind of hardware interface, you need to implement a "HAL component" for it. Typically, hardware interfaces are implemented as realtime components written in C or in comp (a C preprocessor).
look at examples in the source code, the html or pdf documentation for comp, and the manpages intro(3hal) and intro(3rtapi)
one simple example you may find instructive is src/hal/drivers/hal_parport.c
once you have a hardware interface component, then you can hook up the inputs and outputs in whatever way makes sense (e.g., to halui as you mentioned)
shrdlu-: good, glad I could help
ok. i thing the good start up is the classicladder.I want study how classicladder read and write in Halui
make sure the next question you ask me is just as easy
motioncontrol: that's in src/hal/classicladder but I am not very familiar with it myself
personally I'd look at as simple a component as possible (e.g., hal_parport for hardware interface; and2 or ddt for a non-hardware component) rather than a very complicated one like classicladder
ok thanks for all and excuse for my question, i use the EMC and Linux also 2 week.I studing first linux, realtime,patch,emc use and after i want implementation new tool in emc.
i want use labview because i use it for my application
you'll be the first as far as I know
i have create one motion control with g code interpreter with labview at c.please read in google :flexmotioncnc for info
I already have enough projects myself
jepler what is your contry?
you want work in Italy not at beach
but motion control application
jepler: looks like the new ini you gave me improved my latency by 15000,i'll see what happens after i install the new video card
