do I have to go to CVS to get pyVCP to work?
I am trying to get Anders Wallen's pyVCP widget for mesa to work
[00:25:51] <eric_u> http://www.anderswallin.net/2007/09/pyvcp-m5i20-hostmot-4-test-panel/#comments
his file called iotest.xml doesn't make a good control panel
and his pyiotest.hal flile runs until it gets to his variables, and says that they aren't defined
that happens on line 24
it appears that the pyvcp with TRUNK has the same features as the one in 2.1.7
there are a couple of bugfixes in the TRUNK version
modify the .hal file to show what's there
i am trying to get the pyvcp dro to work
can I just use halmeter?
eric_u, no. you were saying that some pins weren't found - add "halcmd show pin" just before all those connections to tell you what pins are there and what they're called
one thing I'm not clear on -- how do I stop all this stuff from running?
fwiw, I just tested it with trunk, and it works fine. I'm trying to figure out how to test it with the installed version on that machine :)
stop what stuff from running?
lsmod shows that I started a batch of modules
if you're talking about the HAL and RTAI modules, you prevent them from running by not using EMC
how do I kill them?
don't do that
use realtime stop
there is no reason not to just issue a halcmd show pin from the command line, correct?
it shows only m5i20.xxxxxx pins
lots of them
the reason to put it in the script is so you can see the state while the script is running, not after it's done
I think I just got the same problem you're seeing though, so I'll say that yes, you need TRUNK or 2.2 when it comes out
I could be wrong - someone else may know how to fix it
that's not something I can do in isolation is it?
I don't think that would be easier than just using TRUNK
if I just cvs .... blah blah blah ... co emc2, do I get TRUNK?
you need the emc2-dev and build-essential packages as well
(you'd need those for vcp as well - it's both python and C, and would need to be compiled)
apt-get install emc2-dev?
apt-get install emc2-dev build-essential
sudo apt-get install emc2-dev build-essential
SWPadnos:I am trying to use the pyvcp dro from the wiki,put the above files into your emc root directory (eg: /home/tomp/emc2-head/)
question is i dont have a emc2-head folder
jlmjvm, I think those instructions are probably to specific
but I think we are in the process of establishing that it's not going to work anyway
I may be able to tell you in a little bit
do you have a link to those files?
[00:50:28] <jlmjvm> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PyVCP
i miss the ssh terminal program I use on windows
I think pyvcp works at some level for emc 2.1.x, I just don't know the level :)
how do you tell what version?
no, I meant I'm not sure of the level of functionality in pyvcp for packaged versions of emc
I am running?
I'm up to the latest version that the updater knew about
err - I don't remember the dpkg / apt query incantation
then you've got 2.1.7
are there later packaged versions?
no, that's the latest
then I'm not holding my mouth right or clicking crooked or something
eric_u: I can verify that the .xml file from anderswallin.net works with CVS TRUNK, but not with 2.1.7.
I thought I had said that earlier - it's the same here
not sure why the 2.1.7 pyvcp just gives a tiny blank window instead of a useful error message though
SWPadnos: ok -- I saw that you were able to test it in TRUNK but that you couldn't figure out how to test in 2.1.7 or something to that effect
ah - I figured it out :)
I always miss stuff in scrollback
so I'm stuck building EMC2 from CVS?
the correct way to prepare a system to compile emc is to apt-get install build-essential, then apt-get build-dep emc2 (to install the packages needed to rebuild the installed version of emc) or apt-get build-dep emc2-cvs-build-dep (the packages needed to install the development / CVS HEAD version of emc)
i have all the pre-requisites, and just ran the big dro using those instructions... (see jimjvm's post 3 lines up )
you may also need to apt-get install cvs if you choose to get the source using the cvs command
but i'd add cd ~/yourruninplaceemcdirectory
NOTE the '.' is followed by a space
hmm, that's on emc-2.1.6
eric_u:the instructions were to specific,put files in home folder and it worked
did goslo-jimbo ever come back and get that big dro we made for him?
I thought he said something on the user list
btw: that page has another m5i20 test panel i scratched up, still untested ( my bad )
same page ;) http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PyVCP
hers the pkg look mid page http://wiki.linuxcnc.org/uploads/m5i20-pyvcp-tab-panel.tgz
I see why I didn't see it, it's an eye test :)
I fail those usually
heh, i still havent figgered how to load a thumbnail, then get a full size pic with that wiki
what I can see looks nice
this full size dro is pretty cool,have my z axis reading now
great, its now useful :)
can it run when emc is running,wanna see if my counts are right
i only change the a and b pin numbers in the hal file
should be able to run
jammed my computer up
how are you typing here then?
had to do a power off reboot
sample rate too fast?
1 on machine,other on net
tomp has disappeared
did you change lines like 'net YphaseA parport.0.pin-04-in +> encoder.1.phase-A' ? ( no i didnt disappear , just slow typer )
yes my a is 12 and b is 15
since it locked things up, doesn't that suggest that the 20 microsecond period real-time thread is too fast?
in combination with his steppers?
ok, how did the hang occur? immediately at running 'scripts/halrun pyvcp-dro2.hal' ?
no,when i started emc2
by itself its fine
you can't start emc while another hal setup is running
instead, you must integrate the pyvcp-dro2.hal with the other hal files of your emc config
so just add it to my ini file?
no, it won't be that simple. For instance, pyvcp-dro2.hal creates threads, but so does one of the .hal files that emc is already using
(at least I assume that's how it works, I am not actually looking at the file)
in other words, you'll have to do it by understanding hal and looking at all the hal files and at the error messages you get until you get it working
yes , makes 2 threads
in the case of the threads, instead of creating them you'd just want to use the two already created in emc (servo-thread [slow] and base-thread [fast])
or you could run the dro on a different computer
i'm not sure how to patch it into your .ini...
but here's some bits to know
the ini will have a 'HALFILE = yourhalfile.hal'
the halfile will 'loadusr -W halvcp yourpyvcpgui.vcp' and will describe the pins
the .vcp file will have the xml describing the gui
the wiki page we were just talking about is a whole world of info
the only downside to adding computers is trying to balance all those monitors on top of one another
12" height gauge, Enco brand $85.92; Mitutoyo $722.57
I wonder if there's - you know - a difference
that's not an indicator stand type thing is it?
I'd rather have a name brand second hand from fleebay
that's where ebay comes into the picture
forget that tgz of the m5i20 panel until its fixed :-[
there's no hal file in there
izzat what you're talking about?
yep, just xml, but even the giu is borqed
oh man, I downloaded it onto my computer, put it on a flash drive, walked down to the basement from the second story, and now you tell me it's not going to work?
sorry, i was trying to test it as you were walking, why didnt you tell me you were walking ;)
I didn't, I used sftp
but that didn't sound as good
dunno why, as you can see it use to run...
where's that hal file though?
I think I left my flash drive in the computer in the basement, brb
no hal file, just a gui, a demo of how to make the gui, wasnt wired to hal pins yet. doesnt matter if its borqd tho...
[01:46:14] <user_> http://cgi.ebay.com/Mitutoyo-12-Digit-Count-Height-Gage-NO-RESERVE_W0QQitemZ110167267923QQihZ001QQcategoryZ20043QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
i'll be working on it tho, i got m5i20, 7i33, breakouts and now 7i37's
I shoulda bought 2 7i37's
that mitutoyo has a travadial on it
18 bids, that may not be the final price
I've got a fowler like this bit 18 " the mag glass is nice. It is a nice tool fowler sells for less a lot of times
[01:49:05] <user_> http://cgi.ebay.com/Fowler-Height-gage-12-30cm-model-83103_W0QQitemZ330163994474QQihZ014QQcategoryZ20043QQssPageNameZWDVWQQrdZ1QQcmdZViewItem#ebayphotohosting
eye chart and height gauge combo
I should have left the travadials on my bp
just to be silly
travdials are kind of useful i guess
even with a dro
on a cnc they sure mean "we don't expect this to work very well"
"we don't trust it and we bet you won't either"
those bp's were the first cnc that their owners bought
so it makes sense
plus they didn't work
although, from the wear on mine, it did work fine
I was wrong, that height gauge went for 125
I predicted that from the bidding
$5 more would have gotten it
but, still too much for me
and who knows how accurate it is
+/- .1 mm
I bought a 24" Brown & Sharp vernier height gage on ebay for $44
was it any good?
eric_u: the m5i20 test panel wont work. it uses widgets that aren't in the distributed source. they're not secret, but didnt make it into the distribution. I'll remove it from the wiki.
without a dial or a place to stick batteries - nobody wants them
that's a great price for a 24"
ok, thanks tomp
lazy people don't want to read a venier scale
does it have a scriber point
not so much lazy, as they know their own limitations
same reason I don't balance the checkbook in my head
no didn't have that - but did come with the clamp
vernier is the way to go
it's important to have a vernier around in case the batteries run out on the digital
* Skullworks-PGAB wanted the Starett 50 reading...
and for scribing layout, i suppose
Anyhows if anyone is looking at that fowler, I can say it is just as nice as the starrett and BS that were @ school
I have several surface gages I can use for scribing.
i was on an old, very manual bridgeport at work
today and yesterday
note: much of the new Fowler is made in chian - and it shows, my Fowler 15-0-15 indicater had the needle fall off in less than a year - and the dove tails were crap.
i wanted to lay the work out before i did it
everyone looked at me like i was from mars
we apparently don't have any layout apparati
I haven't seen any of their new stuff , height gage looks to be older like mine though
toast, don't the compooter do that for you?
i probably could have printed out a drawing to scale
and taped it to the part
and just used that
have a 25+ year old Fowler dial depth gage thats sweet - but I would not buy it new today after the quality issues I've seen in the last 2 years
how do you like depth gauges versus depth mics
in moldmaking i had to have blade deep mikes to check ribs
round was too fat
but lotsa guys would cut off 1/2 the anvil
that sounds adventerous
you can get closer to a wall to measure a depth
I have to agree about recent Fowler stuff
American name on Chinese product, with pricing that's half way between the two
American profit on Chinese product
I think people have bout had enough of the china stuff... hope it doesn't get worse though
it'll be like Japan, originally crap tin stuff, but cheap, then later fine craftsmanship and expensive
user_: when you have a kid/grandkid, be sure to turn it over and look for the "Made In China" stamp.
Just some of those cheap china stuff is soooo poor I can't believe they used metal and machine time to make em.
labor is cheaper, you can stuff 6 ppl in a press machine
it was only 6 in that video?
in the machine, yeah
I think we made the right call _not_ going sailing this evening: http://jmkasunich.dyndns.org/pics/waves-0759.JPG
we went out for dinner with a friend and my wife was going to walk home
until she noticed the heavy rain and mega lightning
Pretty there, I'm 100 miles inland..
has stormy eyes
it's remarkably hard to hold a camera steady when the wind is strong enough that you have to lean into it
get a monopod
I had a tripod
so I built emc2 from cvs with run-in-place set, that's a little more work to run things
(and the first shot I posted was taken with it)
but later I went up in a lighthouse
the wind up there would have blown the tripod away
eric_u, once it's done, it's basically done. you can either install that version or set up icons/shells so that's the one that gets run
it's not like you have to recompile every time you want to run it :)
theres some old buildings like that, not quite light houses, in the harbors in Chicago. I'd love to live in one :) They have big doors to slide emergency boats out into the water.
this one is among the few sharp ones from atop the lighthouse: http://jmkasunich.dyndns.org/pics/waves-0767.JPG
the lake is a bit testy tonight
perch fishin !
cradek: use 'set log' in gnuplot to get log scale plots
for example, 'set log xy' gives a log-log plot

If I recall the sign correctly, that flagpole was removed from the first US navy all-iron ship

GIMP is pretty cool
[03:09:35] <jmkasunich_> http://jmkasunich.dyndns.org/pics/lighthouse-on-hill-0795.JPG
that was shot from the bottom of a hill looking up
so the flagpole and lighthouse seemed to be leaning toward each other at the top
perspective filter in gimp straightened them right up
I don't have patience enough to work with GIMP
wow... washing machine motor
bet that ball mill goes really really fast
oops wrong window
some of the photo stitching software ( like panorama stuff in quicktime) allows perspective corrections, and can be used on individual frames. http://hugin.sourceforge.net/
it took me a while to find the perspective stuff in Gimp, and a bit longer to figure it out
(undo is the greatest invention ever!)
crazy use of stitcher http://www.bruno.postle.net/panorama/barkers-pool/
jmkasunich_: CTRL+C, CTRL+V, CTRL+Z =)
jymmm in Gimp the first two are much less used than the last one
jmkasunich_: I have my trackball programmed for copy and paste (top left and right buttons)
I use them constantly
for photo editing?
Yeah, but for everything
who all here has sucesfully compiled rtai from source?
marque select, copy, paste into new image
I just did
(compile RTAI from source)
and it all worked?
magma CVS from a couple of days ago
hmmm - no, wait. this is the source from the experimental SMP RT kernel
I have the "SpaceNavigator 3Dconnexion" (a division of Logitech) - its the bomb for Google earth.
also for Solidworks
go to www.linuxcnc.org/experimental and download anything with 2.6.20 in the name
those are provided with really no support :)
ok, I need take notes... I just spent all day trying to get linux-2.6.15/rtai-3.3 working...
I think you need magma, and I believe the only way to get any recent version of it is to use cvs
hmmm, this only gets more complicated...
it's pretty complicated if you want to do it all yourself. if you want it simple, then you need to use the precompiled packages somehow
emc2 is best suported on a ubuntu computer connected to the internet and the computer I am trying to get it working on runs slackware(my preference) and cannot be connected to the net...
yep - that makes it more complicated for you :)
you should try to follow the instructions on the wiki for installing to other distributions
there's also a page called RTAISteps which should have some good information, though it is a bit outdated
(ie, most of the versions will have changed by now)
do you know when the next binary version will be release?
"in the next few months"
err - of emc2?
will that include a liveCD iso(for installing)?
there will probably be a new ISO, but until at least April of next year, we're thinking it will still be based on the Ubuntu 6.06 LTS distribution
so EMC will be different but the kernel probably won't be
well, thats a long time, what is involved in upgrading the current Ubuntu liveCD to the CVS version of emc2?
I don't understand the question
when the next EMC2 is released, the liveCD will be updated (soon after anyway) with the new EMC2
can Ubuntu install sources(packages) from disk(usb thumb drive)?
or are you asking what it takes to compile CVS EMC2 on an Ubuntu install?
yes, it should be able to
you can always use `dpkg -i <package-name.deb> to install a package
+/- some other command line options
what I am wondering is how hard it is to install the EMC2 Ubuntu liveCD then upgrade to the CVS version of EMC2
the siki installing emc2 page tells how to do that: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Ubuntu_5_10_and_6_06_from_source
ok, will take a look
it does assume a net connection, but you can use CVS on a connected PC and then copy the tree over to the EMC2 PC (use a flash disk or something)
installing the development packages would be much easier with a net connection
any vague ideas as to next release date?
"in the next few months"
thats 2.2 - or 2.1.8?
yes and no
2.2 in a few months, to get all the shiny new features currently only available from CVS
2.1.8 will come as if and when needed, but will contain only bugfixes
( yeah I did ask for vague... )
and a 2.1.8 if there are any major bugs found before 2.2 is "ready"
I'm still working on the hardware end - so it really makes no big dif to me.
anyone know where I can find a list of files that are needed for installing the development packages for EMC2?(so I can put them on my thumb-drive)
but I was going to start trying to port many of my Macro-B formated marco subs to work in EMC and post a library
have a 2.1.7 box here to run sim for compatability testing with interp
the really nice one will generate the tool path to threadmill female NPT threads.
skyfox00: are you sure you arent just making things difficult for yourself?
that sounds pretty useful actually
I am just trying to get the reset capability for the parport in EPP mode for use with the pluto_servo board.
I had the CVS version running with a buggy kernel and rtai-3.5 and it was working and could recover the parport after an error... but that was with a nvidia tainted buggy kernel.
what is the recomended PCI/ISA EMC2 compatible servo-motor contoller board?
Is there any USB multi-channel I/O board that could use a userspace driver for non-realtime critical events like coolant on etc. ?
if you cannot find one, it would be easy to make one...
if you want a closed-loop realtime usb interface, put on a flame retardant suit first...
no - no need for true realtime for stuff like coolant pumps, E-stop -OFF amp enable, etc.
are you looking for somthing that can drive motors, etc, directly or somthing that puts out logic signals?
but I would prefer something like an 8255
Skullworks-PGAB, look into the arcade game controllers that let you hook up buttons - those should be supported by hal_input
at least for inputs. I'm not sure how many outputs they usually have
been there done that - good for buttons - but not for switches
not likely what your looking for....: http://www.sparkfun.com/commerce/product_info.php?products_id=7841
handles momentary fine - but will trigger a stuck key response if a switch is used
even the USB ones?
I cn imagine that from the PS/2 style
don't know about those - I was looking mainly at the PS/2 type
but think the signal gen is same even if I/O method differes
could be if it registers as a keyboard
It would work fine if people wanted to put alot of extra bells & whisles in the GUI front ends.
so that status of these extra options were shown
those FT245RL boards show up as a serial port and the 8 data lines are just 8 bits... not sure how to interface a virtual com port to emc2 though...
I'm still thinking that tripple 8255 board would be the hot ticket for a nice hardwired control panel
what is a 8255?
that;s a cool little board. too bad it has zero protection on the I/Os
it's a 24-I/O chip fromthe old skool
Anyone know of a mobo the size of a deck of cards or smaller that has ethernbet, and maybe usb or serial, and a CF for storage?
yes was often used on 1st gen ISA cards
yes, but I haven't been able to find it online (saw it at a trade show)
SWPadnos: remember the brand?
we designed one such card, ages ago
Tokyo Electric, I think
it was in the AMD booth as a sample of a tiny computer
is the heatsink larger than the board?
no heatsink needed - it used a 3W eden or something similar
[04:08:16] <SWPadnos> http://www.via.com.tw/en/initiatives/spearhead/pico-itx/
those are close
8255 - http://www.futurlec.com/PCI8255.shtml
It doens't even need to be that fancy, just want to install a minimilistic nix on it.
I really don't understand why anyone would buy that card when the MEsa 5i20 is only $200
SWPadnos: Hmmmm C7 cpu on that thing
Skullworks-PGAB: phidgets is a usb i/o thing, seems crappy but that's all i know off the top of my head
$230 for that board
that's not bad
In itself, no. But I wasn't looking for as many features as it has, just a minimilistic nix install (not BusyBox, necessarily)
[04:12:52] <LawrenceG> http://gumstix.com/
[04:13:31] <fenn> http://www.embeddedarm.com/epc/ts7200-spec-h.html
maybe grab a cheap and small wireless access point and install Linux on it
Jymmm: netgear wgt634u
or a wired access point - either way
what are you doing jymmm?
does mesa make a more rudamentry card - it would seem to me the 5i20 is overkill for simple switching I/O
SWPadnos: That's what I have now, just a tad bulky
Skullworks-PGAB, they do have a 96-I/O dumb card, but I think it's PC/104 only
Jymmmtake the case off ;)
fenn: Bummer $100/100qty pricing
its like $129 single qty
yeah seems most there line is PC104 based
is that too much?
$40 - that's why I laughed
fenn: I think the better deal would be the VIA board
good fast cheap - pick two
good fast cheap compact - pick at most two
in this case, compact is part of "good"
ok, I can accept that
and fast refers to how long you have to surf ebay
fenn: I have a dawg slow connection here at work
musta changed jobs
i thought you were mister 100MB/s
* Jymmm hands SWPadnos a 0
well, that's per pipe ...
or a comma, whatever you prefer
maybe I should try to get hired by them and have an OC48 installed at my house, so I can effectively telecommute
or telecommute effectively
SWPadnos: dark fiber to NY?
I'm a ways from NY, and there's a lake in the way
I can get to a SONET ring pretty close by though
there ya go
well, I think I'm going to try linux-2.6.17/rtai-3.5 next...
that is a nice looking board though... http://us.st11.yimg.com/us.st.yimg.com/I/yhst-27518546784426_1965_109064608
yeah - it is
hmm MESA ISIO
that's just an isolator for parports
useful, but doesn't give you any more I/O than you had
Hmmm optional A/d converter http://www.embeddedarm.com/epc/ts7200-spec-p.php
but it looks much more robust
The ISIO has 4 relay or 4 transistor outputs and 8 opto-isolated inputs. Relay outputs are rated at 2A, 24VDC or 1A, 120VAC. Transistor outputs are rated at 1A, 48VDC. Inputs are 10 to 48VDC. All isolated I/O uses screw terminals. Outputs are disabled at powerup until a specific 12 bit code is sent to the ISIO
Skullworks-PGAB, the reason I'd get the 5i20 (or better) over a simple I/O board is that i removes the burden of faster I/Os from the parallel port. I'd shift step/PWM generation and encoder reading to the 5i2x, and use the parport I/Os for the slow stuff
I may end up buying Jon's PWM amps and controller
even for software step or PWM generation, the 5i20 is better. it has a lower overhead since outptus can be written in larger chunks, and it has 33 MHz bus cycles instead of ~1 MHz, so wait states are much shorter
anyone want a good deal on a new pluto board?
how well is the 5i20 suported/work in emc2?
the hostmot4 configuration is completely supported
I have yet to find a PWM amp with current limiting for less -
that's 4 PWM (pseudo-DAC) outputs, 4 wuadrature inputs, and 32 out+16 inputs (or 32 in + 16 out - don't remember)
I guess I should ask if can run servo motors
Skullworks-PGAB, what does Jon charge?
~$159 or something
$125 /ea for amps + $250 for the PWM inferace
oh, that's pretty darned good
add the in-rush limiter and E-stop breaking card the package will be about $1000
well, for me it should be less
I think all I need is the EEPROM to make my USC a UPC, and I already have the gecko servo interface
$1k for an inrush limiter?
and a resistor
I think the PWM in the new mesa configs will be able to run his amps though - I recall some discussions about that (but I don't recall the outcome)
no, $1000 for the whole thing, including the inrush limiter and E-Stop stuff (plus UPC and drives)
I guess cnc is not for people with thin wallets...
well if they get the hostmot8 functional and could drive his amps...
skyfox00: not if you are moving big chunks of metal around fast
hostmot8 isn't all that hard to get going
but I'm not sure it will work with Jon's amps. they have an odd bootstrap requirement
skyfox00: but there's a lot of uses for cheap slow cnc too
key thing is I have a 130 VDC (peak) 18A DC spindle motor
hmmm. 160V / 20A is pretty perfect for my motors
that is still within the specs for his amps - to run the spindle as a servo
I dont have a job right now, so cheap/slow cnc is thinning my wallet execivley...
though I'm not looking forward to building a powersupply for that motor :~
and getting free multiple-party software/hardware/firmware to all get along without killing eachother has proved to be quite a nightmere...
I'm getting fired on friday
( lucky I start a new job on Monday)
did you quit
or are you seriously getting fired
what will you be doing for your new job?
company got sold
did they sell to your new company?
I got an offere from the new company
many people didn't
bout 1/3 are getting serverence pkg
maybe closer to half overall - but 1/3 in my dept.
well, thats better than nothing, when I left my paper route, one of my old customers sent me a check for $20 several months afterward...
I must have done a better job than the new guy...
about 50% eff
but I have the best quality record in the company for last 3 yrs
what kind of company?
I make fuser rollers
like for printers/copiers?
the imaging drums that transfer images in laser printers and high speed copy machines
how do people generate g-codes without using expencive(non-free) software?
gcam is a start: http://gcam.js.cs/
I have it and was quite disapointed with the lack of user interface....
it would be nice to just take a DXF and "convert" it but that doesnt seem to work for me

Haas VF-0E fed by robot
ok that looks like fun!
i recognize that robot
just another job I have to setup
[04:50:11] <fenn> http://fenn.dyndns.org/sketches/emc-splash/Puma.png
does the robot feed a lathe?
no - it loads rollers between 4th axis centers to have the drive feature added ( flats or drill & tap )
fenn : these are Stauubli robots
We did have some pumas - those are much older
pumas are older
oh, on a mill?(I dont know what a 'Haas VF-03' is)
its not actually a puma, but the same kinematics
i just thought real pumas were ugly
also the machine next to this one has a GMF / Carrol Fanuc with yello cap 4 brush motors
looks like that e-itx board should have a blower, not an axial fan
yes - even the paint color was ugly
these Staubli are scary fast
we had a open house for halloween last year
and you put costumes on the robots and had the guests walk through the haunted factory?
robot would reach down inside a bucket in a lathe, grab some candy, whip around and toss it into the kids pail that was sitting in a little circle on the floor
think they were jumbo tootsie rolls
where does your company operate?
company firing me is based out of MN
new company is 1/3 local here in Colorado Springs, 1/3 a spinoff of Minolta, 1/3 in china
oh, I thought the US outsourced all manufacturing years ago... nice to know there behind schedule...
No china owners
60% Japan 40% US
Japan group own 4 factories in china
I am a bit biased, but I say we need to stop all the outsourcing and bring manufacturing back to the US before everybody forgets how to make stuff...
part of why they bought us was to help fix all the quality issues in the china plant
China still has not learned good tool and die
so things don't work as envisioned
and while they learn good tool and die, we forget... madening I tell ya....
yep - our best old timers are helping design tools for them
* skyfox00 wishes he could learn machining....
machining will be a cottage industry outside of defense work in 20 years
Production will move offshore - OSHA and others will force that
time to string OSHA up with some bright orange safety tape...
I'd settle for some budget cuts, enough to be sure they don't leave the lights on in the restrooms ( at OSHA)
(make it hurt)
and we all know the red comunists who we call the government would never do that...
likewise gut the "clean air act" - while it was a good idea - many of the current regs cause more damage than good - like oxy-fuel
oxy-fuel made cars with carburators run cleaner
but the whole Oxly fuel thing is redundant with computer controlled fuel injection systems that use oxygen sensors.
not that many cars with carbs now days
well, when the government breaks up due to total economic destruction, we can always work up from being cavemen agian... re-envent government as a non-opressive entity.
Thanks agian for all the help and cya later!
well - bed time for me - still going to milk the OT from the old company - another 12hr shift comming up.

i am trying to do some of the pyvcp examples from the wiki,near the end of the page it says pyvcp wont be released untill 2.2,i
does that mean the examples wont work with ver 1.7?
in the end, we ported an early version of pyvcp into emc 2.1.x. The one that will be in 2.2.0 has many more capabilities, and when you give its .xml files to the one in 2.1.7 it will not do what you want.
i was able to make the big dro work,but when i tried the panel with led indicator,no luck
this documentation should match what is possible in 2.1.7's pyvcp: http://linuxcnc.org/docs/html/hal/vcp/index.html
k,thats the page i was reading
I tried the first example with one label and one led on emc 2.1.7's pyvcp and it worked
k,that lets me know the problem is on my end
as so often the case,lol
I guess the advice on how to run it (just 'pyvcp ...') is not right, though
you need to: halrun
then at the halcmd prompt, 'loadusr pyvcp ...'
i did that and it says this halcmd: Usage: pyvcp -c hal_component_name myfile.xml
but no panel,i put the stuff in a file called tiny.xml,does it need to be changed to myfile.xml?
halcmd: loadusr pyvcp -c mypanel tiny.xml
halcmd: pyVCP: Creating widgets from tiny.xml ... Done.
... and the panel popped up above my terminal ...
the "-c mypanel" is required; if I leave it out I get the error message you did.
one last thing -- when you want to incorporate this into a .hal file, you have to add even more words to the command:
halcmd: loadusr -Wn mypanel pyvcp -c mypanel tiny.xml
Waiting for component 'mypanel' to become ready......pyVCP: Creating widgets from tiny.xml ... Done.
"loadusr -Wn mypanel" forces halcmd to wait (-W) for a new component named mypanel (-n mypanel) so that a following 'net' or 'link' statement can succeed
every time i reopen terminal and type halrun it says realtime already running
then command not found
is there a command to stop realtime from terminal
if you left emc or halrun going in another terminal, or made one of them exit in an odd way, you will get that message
"halcmd unload all" followed by "/etc/init.d/realtime stop"
have a led
now i can work on the other examples
the mesa boards 7i33, 7i37 have a T variant, and that means "The -T version uses 3.5 mm screw terminal compatible plugs". This sounds like it would eliminate the need for breakout boards. anybody use 'em?
that came out after I had orderd a few :)
beware the cost and accessibility of the terminal plugs
beware, they don't come with the screw terminals, only the socket to plug them in. after getting the mesa board, you have to go hunt for the right connectors.
each 24-position plug is over $20 (there are two per board)
pete doesn't have a good source?
they'd still be in the $20 range
unless he got thousands
there are also accessibility problems. the two terminal strips are only 3/16 " apart - there's no room for the wires to exit the inner connector if you want them both to face the close edge of the board
there are left, top, and right facing plugs, so that problem can be worked around
I suggested to Pete that he use the right-angle header for the outer connector, but I don't know if he
he'll do that
how is the conversion coming?
if you are the adam I am thinking of..
just compiled the trunk version run in place, I'm trying to use one of my configuration files that work with the official version
and I get this error
Traceback (most recent call last):
File "/home/mill/develop/emc2-nurbs/bin/axis", line 3260, in ?
_tkinter.TclError: domain error: argument not in valid range
with the sim/axis configuration everything works
wonder if that isn't related to INPUT_SCALE vs. SCALE
try changing INPUT_SCALE to SCALE in your ini file
HAL:70: Ini variable not found.
HAL config file /home/mill/emc2/configs/COBRA/core_stepper.hal failed.
Shutting down and cleaning up EMC2...
maybe I've to change in the core stepper
if you change the inifile you have to change references in the hal file as well
but it should not be necessary to do that -- only if I introduced a bug in axis with a recent change ..
and it's better for me to fix the bug than to require everyone to change .ini files
nope, if I change INPUT_SCALE to SCALE in ini and core_stepper, everything remains the same
Traceback (most recent call last):
File "/home/mill/develop/emc2-nurbs/bin/axis", line 3260, in ?

wonder why sim/axis works then?
don't ask to me :)
mind putting your inifile on pastebin?
ah I bet you have a negative SCALE

ok, now it works
skunkworks - I am wiring up my Mesanet boards, Building a pendant, and waiting on a VFD.
alex joni: i have an encoder on my z axis and its hooked up to my breakout board with a and b channel,is there a place on the wiki that deals with adding an encoder
wanting to get ferror
jlmjvm: search the configs for the component encoder
you need to loadrt encoder num_chan=1 (if my memory serves me right)
then add the 2 functions of encoder to base_thread and to servo_thread
you need to get the scale right
and the output from encoder needs to get connected to the axis feedback position
configs?do you mean where the hal and ini file is?dont have encoder component in my configs,
may not be looking in the right place
jlmjvm: look at the etch-servo hal for a starting point for setting up the encoder module
looks like what i need to get started,thanks
could I get a hal module written for this? http://www.electronicsam.com/images/imageset.jpg
sorry - phone camera
what is it?
heres my hal file,crashes when emc starts
[19:24:30] <jlmjvm> http://pastebin.ca/694392
im only using 1 encoder right now,and the a and b pins are right
uh what's the error?
HAL:20:error message here
(20 is the line number)
want me to paste error msg
encoder.2 is wrong
you need encoder.0
and loadrt encoder num_chan=1 is enough for now
if you want encoder.2.* then you need num_chan=3 (0,1 and 2)
my z axis is number 2
encoder on z axis
cradek: it is a interface card for an old image setter
jlmjvm: 'Z axis' doesn't mean you automatically put .2. everywhere
jlmjvm: in this case, this is the first and only thing you are hooking up to 'encoder', so you use encoder.0
just tried it with 0
still no go
yeah but the error is almost certainly different now :-P
want me to post it
well that's the only way anybody here is going to be able to help you
Hey guys are there any other IRC channels where machinists hang out regularly?
there's #machinist too, but there arent lots of people around there
right about not a lot of people there

cnczone probably has a chat somewhere..
if you like white noise
the drummer juggler is great
I have never been in the cnczone chat when other poeple where actually there
I hadn't either but it was a long time ago
I expect it to be like the rest of cnczone
is 'white noise' racist?
Forums are cool, but I always feel like I am chasin my tail..

Question: I am unsure of the pinout for my glass scales, I am trying to wire them up to my MeSA 7I33. Any suggestions for testing this?
use a oscilloscope
Jeez I was just looking for a replacement scale for my sargon/enco
or contact the maker.. and ask for a pinout
[19:47:37] <jlmjvm> http://pastebin.ca/694421,thats
the changes i made
how do you send an error,cant copy
somebody check me on these alternative names... the 7i33 can accept 'RS244" (aka differential ) and TTL ( aka single ended )
adam2 do you know about the cadcamdro list on yahoo?
jlmjvm: start emc from a terminal
then you can select and copy the error
jlmjvm: but the error is probably :
newsig Zpos-fb float
that one should already be defined
jlmjvm: the linksp should be enough
skinnypuppy no i dont, what is it?
hmm - for about a $1198 you loose 3-4 inches of table travel.. :) http://littlemachineshop.com/video/ToolChangeDemo.mpg
Is that the spider looking tool changer?
sort of a tool chain - maybe and upside down spider
I'll have to look at it later, no codecs on the 6.06 box
apt-get install w32codecs
alex, thanks would you look at this pastebin ?http://pastebin.com/m7d2a9cee
[20:04:51] <jlmjvm> http://pastebin.ca/694451
finally got the error msg
jlmjvm: don't see the actual error
skinnypuppy1334: did you add a repository?
k,on the way,that was the dmesg
skinnypuppy1334: try http://onlyubuntu.blogspot.com/2007/03/install-mplayer-and-multimedia-codecs.html
Alex, thanks. I didn't add repo, which is the w32 coming from?
skinnypuppy1334: it's in the previous link I posted
[20:09:04] <jlmjvm> http://pastebin.ca/694459
that should be the error
Greetings people of Emc!
jlmjvm: I already told you that you need to remove the newsig
Yeah those aren't in my sources, thank you
gives another error when i did
jlmjvm: what's the error?
already has a writer?
lemme remove the newsig and resend error
jlmjvm: no need
remove the newsig
then open core_stepper.hal in the same dir
and look for the following line 'linksp Zpos-fb <= stepgen.2.position-fb
and comment that line out
k,will give it a try
your going to have to scale the encoder module correctly to work correctly with you input scale
I think I could have squeezed another 'correctly' into that sentence
emc came on and if i turn the motor the numbers change
motor poer is off
where do i set the cpr amount at?
20480 counts per inch
scale I think
it's up to you actually
you can stick a line like that in the .hal file
setp encoder.0.position-scale 20480
you can use any name you want in the ini file, and reference that in the .hal file
I ment scale pin on the encoder.
so setp encoder...scale 20480 is one way
SWPadnos: he is doing steppers with encoders.
so he has the scale in the ini for the stepper which will be different than his encoder scale.
* skunkworks is thinking out loud
you can add any variables you want to the ini, and reference tem in the HAL file, so it really depends on how you want to set it up
really - cool
so you can add a section called [MY_STEPPER_ENCODER_FEEDBACK]
really? - cool
and a variable in it called THE_NUMBER_OF_COUNTS_PER_INCH_ON_THE_X_AXIS
so add that setp line to my hal file?
and you can set that by using "setp encoder.0.scale [MY_STEPPER_ENCODER_FEEDBACK]THE_NUMBER_OF_COUNTS_PER_INCH_ON_THE_X_AXIS" in the hal file
setp encoder.0.position-scale 20480
that'll work too, of course :)
hmm - wasn't there an issue with the stepgen with using encoders as feedback - like it doesn't reset it position to the 'encoders' position after an estop or something like that?
changed the hal file,still have joint error,was i supposed to put something in the ini file also?
what is the error? following error?
encoder is doing its job already
with it off - does the readout count correctly? like 20 turns equal an inch on the readout?
are they going in the same direction?
That is a cool little tool changer, hadn't seen that one .
i can check
This is the one I considered spider looking,
[20:33:01] <skinnypuppy1334> http://home.insightbb.com/~joevicar3/default.htm
SWPadnos: did you read what I wrote above about stepgen?
yes. that could be a problem, I don't know
this is interesting: http://home.insightbb.com/~joevicar3/Air_Spindle_Plans.htm
I wonder how fast it spins .. doesn't seem to say
he does say 50 IPM taking 0.06" cuts, but he doesn't say how many flutes the cutter is
or if "deep" means chip load or cut depth
guys I have some kind of tapping head that appears to just be a clutch with settable max torque. It also has a (tiny) bit of give axially. Is that used by just feeding too slow for the rpm and letting it constantly slip?
(it seems like that can't possibly work very well)
cradek: isnt it a reversing head?
the float is to keep the tap from snapping, just like in a cnc floating tap holder
you're supposed to feed at the right rate, but if there's a mismatch, the tap will wait for the quill to catch up
anonimasu: no reversal stuff as far as I can tell
cradek: does the entire head rotate
or is there an apparatus to keep part of the head stationary
SWPadnos: but if you feed a tiny bit too fast it would smash it into the thread right?
the whole head rotates, there is no arm
yes, I think that's probaby true
then there's no reversing.
right - need a static reference to reverse
cradek: the tap will pull itself along
no feed necessary
in a BP, anyway
I think it only moves axially a tiny bit (.020)
toast: you mean pull the quill down?
the problem is when it bottoms, it needs slack to absorb the inertia of the spindle
it's possible it's broken or something
you probably want to program some feed with a CNC BP, else PID will try to stop the tap from moving :)
and to get that clutch slipping
that's a f-ugly thing
oh it's cnc
yeah it won't pull anything along on this machine!
ugly doesn't have much to do with how well something works
toast: um, that's f-ugly..
and it f-works
that's f-ine f-or you f-olks
jlmjvm: so the second you turn the machine on - you get a following error - or is it when you start to move?
cradek: cnc tap holders need a lot more play than .020
toast: maybe it's not meant for this machine. I don't know anything about it really
* JymmmEMC lol @ SWPadnos
when i start to move
I'll just wait and use rigid tapping with emc
so when you start to jog - it will error?
I would negate the scale on the encoder
floating tap holders usually have like .100-.250 float in either direction
pretty sure this one doesn't have that
jlmjvm, you may need to fiddle with the stepgen accel and vel limits
it seems to be just a clutch, you're supposed to set it with a torque wrench
setp encoder.0.position-scale -20480 - or does it count the right direction?
or use halscope to display what is happening with commanded & feedback positions during the short time you try to move -- that will give you a better idea what is going on
cradek: that's probably just a manual tapping head
for a drill press or BP type arrangement
jepler: what? systematic aproach? bah
it's QC30, I bet I could sell it to a manual BP user
oh wait, I have R-8
(and a set of tpamatics :) )
and tapmatics, which work much better
i'd like a collapsing tap head
jlmjvm: yes what?
I'd like it if MTD would send me my f-ing servo mounts
yes its reading the right way
ah - ok. Jepler really has the correct way to see what is going on. use halscope.
and my rapids are slow right now,60 ipm
try moving much much slower than that
what if you jog slow - like 1ipm or such
jepler: I think 3CFM @ 90 needs a non-toy compressor
use MDI to do something like G1X1F10
3SCFM @ 90 = $100 or so compressor
SWPadnos: I think they're more even at HF
was doing this same thing yesterday on mach and it could read at 100 ipm
jlmjvm: what is your following errir set to in the ini?
I got one at an auto parts stor (slightly on sale) for $89, it says 4.2 SCFM @ 90 PSI
it also says 3.5HP, but plugs into a 120V outlet, so it's probably wrong
that's those fake HPs
and probably fake SCFMs too
"4HP shop vac" :-)
I would think that would be more than enough.
ferror that is.
jlmjvm, you have a setup error, and you'll need to use the diagnostic tools to figure out what that error is
cradek: wasn't 3@90 what that harbor freight 56krpm grinder required?
I thought it was 2@90
halscope is probably the best tool at the moment, because at the moment, nobody knows exactly what's going on
and without knowing what's happening, it's hard to fix it
Micro design requires only 2 cubic feet per minute at 90 PSI to deliver 56,000 RPM.
I stand corrected
wasnt i supposed to add something to the ini file to point to the encoder scale?
jlmjvm, not necessary
but you should make sure the scale is correct before going on
it seems by your account - it is working correctly - 20 turns of the leadscrew is 1 inch.
in the display
ie, manually turn the motor shaft/screw to move the table 1 inch, and verify that the display shows 1 inch of movement
its doing that
does it go the right way?
ok, and if you don't use the encoder feedback, but use the stepgen feedback, can you jog?
and when you do that, does it jog in the correct direction?
yes,was moving it yesterday
you can experiment a little by setting ferror very large - like 1 inch
are you sure software counting can keep up with your encoder rate?
will try,but was i supposed to add something to the ini file?
just to be sure, you are exiting from EMC and restarting every time you change anything in the hal or ini files, right?
ok - just had to check ;)
jlmjvm: no, you did not need to modify the .ini file if you put the encoder scale explicitly in the .hal file
you have the option of using an ini file setting for the scale (or anything else), but it's not required to use one
just wanted to make sure
lemmee open up the ferror setting
open up both of them.
I called and got the pin-out for my glass scales: 1-A Channel, 2-B Channel, 3-+5v, 4-Common, 5-Ground, 6-Blank. Whats the deal with common and ground?
the A and B channels may be either (a) isolated from the power supply or (b) common + instead of common -
some big dummy had the pins backwards
i swear when the power was off the motors it was reading right
it has to be right, and also it has to match the motor
it's more important for it to match the motor
(as far as following errors go)
swapped the a and b pin # and its working
ok. you could also have negated the scale as skunkworks suggested
jlmjvm: negating the encoder scale I think would have done the same thing..
* skunkworks thinks now jlmjvm should now play with adaptive feed controll....
lets rock n roll,lol
* SWPadnos thinkd skunkworks needs to take his meds
err - thinks
i really appreciate the help from everyone
any time. just remember to put it on the wiki if you discover anything major about steppers+encoders :)
Does anybody know if the Mesa electronics 7I37 card can output less than 48vdc? for I/O commands?
jlmjvm: you really need to post this on cnczone. This is always brought up.
im the only guy on the block with encoders on his steppers
So - now if you stall - do you get a following error?
yall can have a copy of my hal and ini if you want
no thanks. I'd rather have you put it on the wiki ;)
im sure it will
lemmee give it a big accel and stall it
me,on the wiki
just set the axis vel limit to 1000IPM and try G1X10F500
but set the ferror back down first :)
he should be able to measure the following error - and as it increases slow the feed rate down using adaptive feedrate.. I think it would be a cool experiment..
oh yeah,jacked the acceleratio up from 6 to 60 and it gives an immediate joint following error,doesnt even move
thats gotta be working
plus its showing up when i home out the axis,-.0002,.0001 etc
i think this is gonna really help
im ready to have a keg party now,this was magor to me
what base period are you running?
its reading at 60 ipm no problem
yah - you should be able to do 150ipm no problem
should be able to get 100 ipm like i did in mach yesterday
150 would be awesome
what is your input scale.
remember - you can output at least twice as many steps as you can read
the cool thing is i had these encoders all along
the encoder counting is going to be your real limmit
you probably won't be able to count past ~90 IPM reliably
SWPadnos: explain? you mean doing doublefreQ?
yes,they were higher count than i wanted,but they were on the motors i bought
yes, doublefreq is part of it
but you need some margin for reading quadrature that isn't needed for step generation
and they were 250.00 encoders,wish they had an index
AH - but he should be able to count at 50khz shouldn't he? with base period set to 10000?
oh - I think I had an extra factor of two in my head
so that is 146ipm
100 is prolly all i will go
no, at most. if latency is 0 and the encoder has perfect 90 degree phases, then 50 KHz is doable
and at 60Hz?
if latency isn't zero, then the least time the encoder needs to be at one state is 10000 + latency to guarantee that the software sees it
oh, nm didn't see the K
if the encoder isn't perfect, then that restriction is on the shortest phase
so if it's got a "short pulse" in one quadrature state - say only 75 electrical degrees instead of 90, then that short state needs to be BASE_PERIOD + latency_max long to be noticed
in that example, 75 degrees is ~1/5 of a full cycle, so a cycle of 4 counts = 5 *(base_period+lat_max)
so it works great, until you start looking at the fact that nothing is perfect ;)
alright lets get started on that adaptive feedrate,lol
opk - time for me to get back to paying work! ;)
thanks for the help
I could have swarn though that I was counting encoders close to base period... but I don't know for sure..
but that is an argument for another time.. :)
you could have been
thats how we say it down south
ahh coulda swahn
SWPadnos: this is all I have http://www.electronicsam.com/images/KandT/servostart/Fastermouse.png
jlmjvm: atleast get a wiki up and I will post it on cnczone
btw,couldnt this same scenario be used with a gecko g320 setup by also connecting the a and b encoder wires to a 2nd breakout board also
how do you get a wiki up,never done 1,and no smart remarks,lol
never posted before
still in intense learning mode
back in a bit,gotta eat supper
jlmjvm: glad it works
jlmjvm: the wiki is pretty straightforward
gonna check it out
first thing read & try to follow this page: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?BasicSteps
i think this is an awesome safety feature
once set up right, you can have unstallable steppers :P
basicly if the stepper starts to lag behind, you adjust the feedrate to go slower
just like marris is doing
if you prove it working :)
that would be awesome
we all think it should, but so far no one bothered enough to try it out *blush*
i will try it
gotta get my 2nd paraport installed tomorrow
then i can wire it all correctly,was outta inputs,had to disable y limit switch
2 ports,many inputs
I would personally try to get my hands on some hardware counter for the encoders
I'd trust one a bit more than software counting
may look in to that later
just glad its working
alex joni:shouldnt i be able to do this with gecko servos also,run a and b to gecko and second parport?
SWPadnos: have you hacked any GPS modules/antennas by chance?
SWPadnos: I was just wondering if I unsoldered the ceramic antenna from the PCB, and tossed in some RG-58 or RG-213 if I'd fubar anything?
JymmmEMC, I wouldn't bet on the antenna being 50 (or 75) ohm
it may be, bit you should check first
SWPadnos: I was hoping it would be 50ohm
no identifying marks on it, but maybe I can find the specs. it be a pain to find a balance
well, as oen of the guys in my national guard unit used to say "shit in one had and wish in the other, and see which fills up first"
yeah - that's why I've remembered it for 15 years :)
Ok, if I decide to do this as a test, is there any way for me to check once I've unsoldered everything?
I got crap for T/E
only with a spectrum and/or network analyzer
I was afraid you were gonna say that =)
The one I WANT is only $68,000
it's OK. the newest spectrum analyzers are cheap - only around $9k
Agilent, thank you
HP to me still =)
I have one with HP on the front
I'll have to check the specs, to see if the module has an antenuation var I can pole.
see if belden.com is back online

Hi all... sure am glad those weren't MY dash 8 legs having problems in sweden and denmark
Twingy, I've been playin with Gcam. Pretty cool
next release will have a few more bugs worked out
gerber -> g-code is much improved too
graduate school is eating up all my time though
Cool, do you have a set date?
think there's one minor bug I need to take care of... soon as I get 2-3 hours free
you can grab a sneak peak if you checkout subversion repo
I'll probably just wait for the iron out.
next major features are 4th axis support and dxf/stl + contour pocketing
is 4th going to be rotary?
those still require a fair bit of planing, but contour pocketing code is almost identical to the isolationing code I wrote for RS274X importer
yes, rotary 4th axis, i.e. lathe
before I jump into that stuff I want to take a step back and optimize a few sections of the code
I'm a big code optimization zealot
it'll probably be 12-18 months before said features are available
the project has been going for about 18 months now
It's pretty usefull, kudos
for basic stuff, yep, for complex stuff you'll probably want to use solid works
I use mastercam X @ school for anything too hard.
another good app
Runs the hell outta the heidenhein bp, I haven't tried any McamX posts in emc but should be attempting soon.
Speaking of heidenhein, is there an emc gcode that will allow incremental rotation around a set pole? Like g10/g11 heidenhein?
Ok, I must be clueless today, this ceramic patch antenna only has one connection to it. Am I missing something here?
dont antennae usually have one connection?
