has anyone run a pick and place machine with em2?
ive not heard of it, but... pick and place machines dont usually use gcode, and few use emc2 w/o gcode
hmm. I wonder if orocos would be a better fit...
I don't know much yet, but I have a couple of older pick and place that I just got, and have thought of retrofitting one at some point.
pick&place with linux http://www.msl.ri.cmu.edu/publications/pdfs/Diploma_thesis_C_Niemeyer.pdf
irc is great. Thanks!
emc 2 can likely handle th ehardware and make it move, i just meant pick & place didnt usually use gcode
so you can have a lot of fun with emc2 and your hardware
yeah. I don't know what these machines take. They have 3.5" floppy drives.
I was thinking maybe a combination of gcode with some custom components and code would work.
that thesis is vision driven
download some manuals for commerical pick and place and see how they do it
I see that. These are also factory style pick and place. Mine are for SMT electronic components.
if they got drives, they're likely 'smart'. maybe you can go downstream far enough to find a spot where emc can take control
I have the manuals for these machines. As far as information on the web, I can't find anything at all.
That was my thought.
they use a camera to align components...
I'll be back in a little bit...

anyone happen to be a dentist
alk no more info than lspci -vvv
archivist did u suss it?
no went home and just got into work
cat /proc/ioports http://pastebin.ca/1428280
shows its there
did u try moving the output to pin-01 just to see if it worked?
it seems odd that parport_pc sees the card and detects the correct base addresses
its annoying that nothing indicates which port is which
yeah i found the same, i used the hal scope and just waggled a pin whilst checking which parport it was
been waggling pins for hours
it sounds like the card simply isnt compatible
as u have gone thru all the usual steps to make it work
i had a netmos based card 2XSer 1XPar that just would not work
"all the usual steps" thats kinda undefined
as the first of the two new cards stooped a boot and this card has no output, I do lean towards crap cards
stopped it booting, wow. might be worth trying it in a different pci slot
but getting parport cards is getting less easy
out of interest, is it possible for u to test the card under windows and print via it etc?
seems these cards have been around for a while http://his.luky.org/ML/linux-kernel.2005/msg23170.html
it takes an 1/2 an hour to get in the pc case to get at the card and another 1/2 to reassemble
not a normal case
the motherboard integral behind the LCD monitor in an industrial case
whats hapening freaky people
hello and how are you today my good fellow
thats no good
4:52 am here
ordered my stuff from mesa today
jmkasunich, awake this hour!
heh I was awake at that time last time i was dealing with magmotor
oh i got a ceramic knife for $6 today, tis somewhat nifty
archivist: not by choice - I have a deadline
So i got a bunch more to give out as presents ;->
hehe get it done!
whatcha workin on?
building a CNC mill
taking to the fest?
I'm planning to take the table assembly to the EMC-Fest in two days, so I can do some critical machining on a large mill
I had to get the frame assembled tonight, so I can do one more machining operation tomorrow, then ship it, before I catch a plane the next day
and catch up on sleep on the plane
gonna make it?
I think so
thats good then
else carry as baggage :)
its a bit heavy for that
see theres an application for my aluminium mill archivist ;->
not completely out of the question, probably 40-50 lbs
machinists can be productive on their aircraft l-> just like office weenies
how bout you archivist up to much?
table is a piece of 3/4" thick 2024 that goes on top
trying to get a 5th axis working, hardware done but parport is being an utter pain
the table is 11.75" wide, the frame is a bit over 8" wide
the linear rails go on the bottom of the table, next to the frame
for a rotary table?
no - the round hole is where the X motor goes
ballscrew underneath, "ring frame" wraps around, Y axis is above the table
archivist thaught about using a mesa board? or not much point for steppers?
and now, sleep
Valen, cost of getting one here compared to parport
$229 isnt *that* much ;->
its a lot on my wages with redundancy on the way
ahh sucky :-<
so whats the parrport doing to you to be no fun?
not putting out anything or not enough?
:-< thats no good at all
not using an invalid pin (one that you cant drive) or anything silly like that?
:-< that would have been nice in a way
bah cannot download chip data without signing life away http://www.moschip.com/registration.php
bunch of bar stewards
thats a new insult to me
wee that "work around" works
heh its a cool site, lots of "odd" places are listed in it too
like electronics companies ;->
I have been known to put a pile of false info to get around them :)
I dont even feel bad about doing it anymore
I run my own mail server so i setup a temporary email account for the "authentication" email
a place related to bugmenot (or it might even be them) offer 15 minute long email accounts for the purpose of getting past those
hehe good workaround
skunkworks: I get a 404 not found on this link http://timeguy.com/cradek-files/emc/DSCN6290.JPG
in your message about the Kearney & Trecker
BigJohnT: thanks - I will take a look
I will have to ask chris if those pictures are still on his website somewhere

forgive me for I am about to sin..... are there any special considerations for installing Wine on an RTAI kernal like EMC?
say 100 hail Maries
can I use a do while loop?
steve_stallings: no special considerations
the same consideration as normal: it's pretty unlikely to work for any app you actually need to run
* jepler hates wine
* alex_joni has mixed feelings
I once had an win98 install on a hdd, and I pointed wine to that, after that a lot of apps just worked
obviously not _very_ advanced stuff
freemill is under wine here
i'd rather use wine than windows
my schematic capture stuff is known to work under wine, and there are claims that PCAnywhere can be made to work
PCB layout does not, at least in previous attempts
that may be solvable since the issues were with security key stuff
wean yourself off the dark side
cannot, the PCB layout tools available under Linux still come up short and I have two decades of experience with my current PADS tools
eagle is available under linux
its not too bad
kicad is ok, it has a ways to go but its got some funky features
kicad is slow to build up a user base, I started the #kicad channel to make a place to meet
the parts library is the biggiest hole with it
make new parts :) write a converter from other formats
might get in trouble for importing everything from eagle ;->
Eagle is usable but still much less capable than PADS, KiCAD is far short, usable only for simple circuits.
at least by my definition of usable, ie. get the job done now, not fight the tools
Im a 20+years user of PCAD so I realise the shortcomings
it seems all the good low cost tools have gone through multiple buyouts with detrimental results, I still use a version from many years ago in preference to the current stuff with its new bugs
hehe /me still on the dos version
well I don't go that far, just back to the first true Windows version that was stable
dos PCAD was very usable and the windows replacement less so, I stuck
I am a sucker for hi-res graphics and fast processors. My old ISA bus proprietary hi-res graphics cards had to be retired.
Number 9 video cards, about 2k by 1.5k resolution with hardware pan and zoom, cost over three grand when new.
.. and the monitors were not cheap back then either...
I have an old sun one somewhere
weighs about 400kg
the ones we used were typically BNC input, multisync and worked on SUN, Apollo, etc.
I remember the Prices quoted for Elsa Gloria video cards.. boss wouldnt pay
we were doing some boards with up to 200 thru hole chips, without hi-res you spent your whole life panning
I had a 37" 1080P TV as my monitor at one stage
was great for headshots in FPS games ;->
I'm looking at getting some new monitors now, a pair of 23" 1920x1650 or something like that
those should be fairly cheap these days
£1000 for 1meg of expanded ram so I could do bigger boards on my AST
* alex_joni still has a 387 coprocessor somewhere
cant remember if it was a 286 or 386
yeah about $250-300 australian
hmm.. seems it's 287
I have a 386Sx that i want to get running linux and PPP over serial for IRC
I am very happy with eagle. The learning curve was a bit bumpy but I am very supprised by what it can do.
* alex_joni runs home
[14:22:18] <alex_joni> http://failblog.org/2009/05/20/city-sign-fail/
Actually - what really got me into what it can do is by looking at others works. (jmk layed out a board for me which really opened up what could be done) (of cource I think it was the first time he used it and took him about 3 minutes to figure it out :))
dont bother too much with the auto router
I use it to get things close to where they should go then run it all by hand
Nope. More of a parlar trick ;)
we do mostly 2 layer SMT stuff, so autorouters are not much help, even the Spectra stuff that costs $$$$
human wins, 99% of the time
it is really all about placement and pin swapping, programmable logic helps a lot
I think it is pretty http://www.electronicsam.com/images/KandT/servostart/schem/latestcurrentlimit/latestboard.png
in a scary sort of way
only 1 via ;)
mainly becaus I gave up ;)
what I'd like to see in eagle is a "pinswap damnit" command
I'm all the time forced to go into the library editor just to make a pad swappable
jepler: when are you guys driving down?
I'm pretty sure I will get there tonight
bus willing? ;)
I'm taking bets on the bus's mileage - winner gets to fill it up!
I bet skunkworks161 is closest so far.
any hints as to what the bus is?
steve_stallings: my portable-house project
lets see, Kansas is kind of level isn't it, maybe 9 mpg
cradek: is this anywhere on your website - If I recall it is the servo mount for your little lathe http://timeguy.com/cradek-files/emc/DSCN6290.JPG
skunkworks161: sorry, I can't find that image anywhere.
That is ok
well, it wasn't a lie at the time.
I put it back at that URL so your link is unbroken
Cool - Thank you\
heh, that's one of the few things I cut out of aluminum on max
so glad I don't have to do that anymore
Suppose I have three 48 volt switching power supplies, any problems connecting them in series to get 144 volts to power an H-Bridge?
driving steppers or servos or what
A DC motor.
I'm just wondering if weird stuff happens when you connect switching power supplies in series.
I understand that to connect a couple of switching power supplies in parallel, they need to be designed to share the load.
I'm guessing this is not the case in series.
identical switchers in series should be happy with regulation, but there are other issues
like where ground it.
back EMF that causes the voltage to rise will make them unhappy, and a large cap across the output is good for motor driver but initial charge up may trip current limit on supplies
input/output isolation of supplies will need to be considered, if your stacked supplies approach this isolation limit bad things could happen
there can be issues with the switchers at low loads having weird output ringing causing interaction between the two
hmm...So an unregulated power supply may be better than the switching supplies in series?
I think it's a pretty sure thing, not a "may be"
I mean transformer, rectifier and a filter cap.
I think that's the standard way to do it
are unregulated power supplies usually preferred over switching supplies to servo motors?
for servo motors...
both my commercial machines use transfomer/bridge/caps for the servo power supply
3 phase transformer is typical (much lower ripple)
uh-oh, how's progress?
and still much to do
[15:20:28] <jmkasunich> http://jmkasunich.com/pics/imgp2931.jpg
pic looked good this morning
the camera autofocus liked the soldering iron
yeah, I'm a bit underimpressed with my camera's focus
BJT-Work: yes, except for the end plates - they're 7075
jmkasunich: wow - very nice
cool, did you make the bed?
and the table top (not in that pic) is 2024
the top part
casting or builtup?
is it a weldment or all bolted together
that pic is the "frame" the table itself is a piece of 3/4" plate that will be glued and screwed on top, after I flycut the top flat and parallel at the workshop
forgive me for asking, but what is it? i'm sure its not an ice cube tray ;)
screwed and glued with structural adhesive
geo01005: table and X axis for a small gantry mill
what you see is 24" long x a bit over 8" wide
the table plate is 26" long x 11-3/4 wide
the linear rails will go on the bottom of the table (facing down), just outside the little "lips" on either side of the frame
the gantry will hang from the rails, and be a loop that goes all the way under and arround the top
X ballscrew goes underneath, where you see various bored holes and recesses
That is going to be one nice machine
I sure hope so
as usual, I wind up overbuilding things
won't really know until the first time I try to cut metal with it
sure looks sturdy for a PCB mill 8-)
yeah, I'm definitely aiming for a metal cutting mill that also does PCBs
the spindle will be about 1/2 HP
but small tools only - 1/8" shank
still planning on a wide gantry that can accomodate head tilt like you mentioned at last fest?
not on this machine
strictly 3 axis
jmkasunich: get back to work and don't come back until you have more photos for us
so.... yet more projects in your future
why are "edit" and "edit tool table" under file grayed out in axis ?
rotate 180 deg on the bench and make into a trunion 5 axis
piasdom: because you have not set [DISPLAY]EDITOR (doc here: http://www.linuxcnc.org/docs/devel/html/config_ini_config.html#sub:%5BDISPLAY%5D-section
cradek: thank you
I wish guis had a "why is this disabled?" feature
I think it would help with discoverability
wonder if something like tooltips could be used for that.
can you have a different tool tip if it is disabled?
(remember the question mark button in windows 95?)
seems a good idea
BJT-Work: not sure.
* archivist expects over the weekend :)
archivist: I don't think you can do it in just one application and have it discoverable. it's hard to do anything that all applications don't already do.
we've had 10 years of pretty much no innovation in GUIs and this is where we're going to be stuck for a while...
dunno, its someting I do in html and in that case I can think of a method to change wording
I guess we got scroll wheels in the last 10 years
just change the hover text on greyed
quick-n-dirty mockup: http://jmkasunich.com/pics/imgp2932.jpg
archivist: sure but I don't know if it would be discovered (because a user doesn't know to hover over a disabled thing to tell why)
cradek: what HOME_LATCH_VEL do you use on your max and what type of accuracy do you get?
pay no attention to the clamp
jmkasunich: that is going to be so slick
alSMT: since home switches are read in the servo cycle, you should go a speed no faster than a whole or half step per servo cycle.
* archivist notes the clamp for later evidence
alSMT: I get pretty good repeatability (homing to the same step over and over)
jmkasunich: are those 123 or 246?
the quill is going to be 1.5" bar - I think that piece I used is the right size
ah I see a roll of paper towels now - I was struggling to get scale
a better representation would be if I had bolted the Y rail to the front of the 246 blocks, instead of on top
that way the Y carriage could use the full length of the rail
you're going to flycut that .750 plate?
and of course, the 246 blocks should be outside the width of the table, and the X rails underneath
at MPM, I will flycut the top of the frame, mate the table to the frame, cut the t-slots in the table, and flycut the top
seven 1/4" t-slots on 1.5" centers
does that mean for T nuts that take 1/4" screws?
do you think it will warp when you cut the t-slots?
that's a nice size.
where do i place the EDITOR = gedit in my ini file...it's not listed
bjt - hope not
I think I want to cut the slots first
then flip the table over and flycut the bottom in a zero-stress state (3 point clamping, etc)
then glue the newly flat bottom to the frame, and finally flycut the top
cradek: thanks again
jmkasunich, are you going to skim both sides of the tabletop
I'm gonna think that thru at MPM, and also ask Stuart's advice
going to be one solid pcb mill
BJT-Work: I see that the AXIS-specific section is under the [DISPLAY] section, but maybe it could be more explicit that those things also go in DISPLAY. what do you think?
* BJT-Work goes back to read it again
yea, it is a sub sub section under the display sub section. It would look better if it was a *subsubsection so the axis part is not numbered I think
i added editor..but it doesn't work(still gray) i restart axis..do i need to restart system ?(don't think so)
i placed it under PROGRAM_PREFIX
like this EDITOR = gedit
placed what under PROGRAM_PREFIX?
oh under that line you added the new line, I understand
did you turn machine on?
no...just tried to edit a file
maybe you edited the wrong ini?
got it...guess it took time :)
what was wrong?
don't know...i restart emc a number of times
was only editing the one file

good night all
g'dnite mr Joni
i'm interested in using a CNC machine to do 4 or 5 DOF laser cutting.
looking at the wiki
the one thing i'm having a hard time discerning
is what kind of hardware linuxcnc is used on
(cutting foam with a fiber coupled 30w diode laser)
(i'd been half intending to build/modify a reprap for the purpose)
hardware? PC of some sort
with as low latency as possible
i dont own any now-- part of the reason i was considering bui/modifying a reprap
from homebrew to retrofit
anything you can hang motors off of, or has motors pre-hung
rektide, some examples http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Case_Studies
