I was riding my bike in bear country, and I thought I heard one
decided not to circle back to find out
it would be cool to see one if it wasn't dangerous
Popeye's Chicken Earth Day Special... 8 pieces (2 each) for $4.99
JymmmEMC: is thaat today?
Yeah, TODAY ONLY
ds3: Either off of Saratoga or Capital
which one on capital? by 87?
[00:31:43] <JymmmEMC> http://maps.google.com/maps?um=1&ie=UTF-8&q=popeyes+chicken&near=San+Jose,+CA&fb=1&split=1&gl=us&view=text&ei=0LbvSa-fMZ_qtQP26vnYCg&sa=X&oi=local_group&resnum=4&ct=more-results&cd=1
C or D, I went to D
ds3: If you go, bring a friend, each get a boc of chicken for $5.45
I am closer to B/E
ds3: Ah, ok. Just thought I'd pass on the special to everyone =) You can't beat 16 pcs of chicken for $11 (if you bring a friend)
indeed... that is a good price
I am tempted to drive out to the campbell one
I didn't know there was one in Campbell
isn't the saratoga one officially in campbell?
the border between sjc and campbell is strange...used to go between the two cities just driving straight
yeah, it's just on the edge, might even be County area
the bear is going to be disappointed, no chicken
eric_unterhausen: the bear?
see my previous post about riding my bike past what sounded like a bear
better chicken that eric's =)
you reminded me that I missed 50 cent iced coffee day though
garage delivered today... some assembly required.
spent the last hour drilling a 2 inch hole thru the rim joist of the house so I can have a little power by the garage. Old house rim joist was over 8 inches thick solid. Pain when your hole saw can only drill 1 inch deep.
drill - chisle - drill - chisle
I bought a big, honkin' drill at Lowes
I don't know if it would be big enough, might have to drill two holes
IIRC, it was $30 and at least 10" long
skunkworks: Dude... chainsaw
skunkworks: never said it had to be a ROUND hole =)
there used to be a guy around here that did nice carving with a chainsaw
don't think he could make a 2" hole though
you could maybe do it - if the bar was about 2 inches thick. slowly spin the chainsaw as you push the nose in. Can you say kickback>
there are chain mortisers
for post/beam house construction
skunk why not just drill a ring of small holes
then connect the dots
or enlarge the holes until they touch
though really i dont see the problem with a bigass drill bit
first corn of the season ...mmmmm

hello, how fast is the emc servo upate loop?
tomp: but you can change that
I think there are machines running at 5kHz
alex_joni: logger v2?
alex_joni: how so?
don't feel like v2-ing anything atm :D
alex_joni: you didnt see my link?
I saw it ;)
alex_joni: and you grabbed a local copy right?
err.. not really ;)
can you put a diff on codepad ?
alex_joni: Come on dude...
* alex_joni is at work, kinda busy
I gave aoo the details
alex_joni: it's just two lines that need to be changed
I looked at line 411
as you said...
keep reading what I said
and 657: my @uris = getURI($msg);
alex_joni: I closed the window already, gimme the link to the codepad
didn't look relevant
I think I see it at 671-673
[08:21:02] <alex_joni> http://codepad.org/0Y0iOgEr
634 & 672?
you sure thats the right link?
ah there it is...
633 was the original, change it to 634
minor nag, when I hack these, I usually put a #FIXME-AJ before the change
so I can easily find it :)
alex_joni: Did you read the top?
I've prefixed each change with '###' so it'll be # easier for you to review
alex_joni: Lines 3 - 13
too bad searching for ### brings also #############################################################################
next time #--
better #JYMM ;)
that's unlikely to come up anyways
yeah, hang on
I'm logging. I don't understand '', JymmmEMC. Try /msg logger_emc help

I log to a database so I can add searching

Im about to fix the viewing side so viewing across a date boundary is far better
the poll "EMC Version you are using " needs emc 2.3.x adding !
do we ever see any results from the poll, does the poll do anything for us
makes an interesting graph
i wonder what the estimated global useage of EMC2 is, its probably very hard to tell
I think the map helps there
perhaps but again that depends on user interaction
and perhaps download stats
i guess there is a high percentage of EMC machines that are not internet enabled too
I just checked if my emc box had any internet jobs queued http://askmonty.org/buildbot/waterfall?branch=5.1
yeah thats a nice display
that means a bunch of remote machines can build and test some code
I know one or two solaris boxes will get added there this weekend
alex_joni, nice to know :)
all greens :)
warnings on builds
true, I was looking at the top line
main site should point to http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Development
and that could point to buildbot info for those that want to help
* jepler debates between getting a "loose" mpg (just the wheel) or a full pendant with knobs, buttons, and enclosure
it's nearly 3x as much for the full pendant at the site I'm looking at
damned intro is enough to send you away
yeah I hate that kind of crap too
If I tried to make the rest of the pendant it would end up sucking
I think the AXIS integration is better than these separate x/y/z/1/10/100 knobs
if you also think that, all you need is to mount the wheel somewhere.
it is real handy to have an axis selector next to the mpg
if the mpg is next to the keyboard, you pretty much do
I'm never out of reach of the keyboard on my system, though
jeff's machine is small and he wouldn't need to follow the tool around with the pendant in hand.
.125ft3 working volume
.. or about one gallon
I'm thinking like my mill where I have to go to the screen and select an axis then put my head in position to see it move and the mpg is on the x slide
sounds like the keyboard is bigger than the mill jepler
what would be awesome is 3 light-up pushbuttons for axis select
yeah, especially if you could work them without looking at them.
so the gui and the mpg would both share the same "active axis", and both would indicate it too
when you press one it lights up and when you press the next on the prev one goes out and the new one comes on?
that would be cool
and if you hit "x" on the keyboard the light changes too
or if you jog with an arrow key
that would be real nice
ugh, I can't see shipping rates on cnc4pc without creating an account
i hate that
I'm probably going to do a cheapy conversion on our existing mill, then look at doing a better one starting from scratch
still, I hope to get decent accuracy with the existing leadscrews by using those linear scales
last time I ordered from cnc4pc the rates were ok
Valen: what kind of existing scerws?
acme have too much backlash for that to work.
we are going to put an anti backlash nut type arangment on it
also, you can't climb mill, which is very important on a cnc
oh, interesting, what kind of setup?
the simple kind, a second acme nut and a bigass spring
BJT-Work: you could make your fortune selling these miracle devices: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320359594296
why cant we climb mill?
we are planning on putting a gas strut or something to take the backlash out of the quill
because the cutting forces will pull the work into the cutter because the table is loose
the table shouldn't be "loose"
your spring arrangement may make it ok for very light cutting
provided the spring force is > than the force from the cutter it should be ok
by spring i am thinking car valve spring btw
how long do you think the nuts will last with that kind of force on them?
the "backlash" nut we are thinking to lathe out of delrin
moderatly hard plastic
it will be somewhat "disposable"
both nuts delrin, or just one? (they will both have the same force on them)
the force only needs to be a little larger than the largest static force
so the wear should only be ~2x normal
just one, trying to reduce the friction, make it a little easier to spin
let us know how it works out - sounds interesting.
probably won't be as good as a ballscrew system, but if the "encoders" are good for 5um and the screw is somewhere near consistant then the servo loop should hopefully be able to handle it
Know any handy high amp low volt controllers?
the fan motors run at ~12V but can pull a fair number of amps
ATX power supply?
the power supply i have sorted ;->
2nd hand truck battery and a 300W charger ;->
what do you need to control about a fan?
the fan motor is what is driving the spindle
using it as a servo motor
that seems a bit out of the ordinary
$10 for a "750W" motor cant be all bad
probably closer to 100-200W in a servo application
it's a 62A 12V fan motor?
something like that
that is a "peak" rating o course
they arent little lol
[14:10:04] <Valen> http://www.robotmarketplace.com/products/0M-EVCCW.html
they are pretty much the same as that
can you upgrade from acme to something like a kerk brand screw? http://www.haydonkerk.com.
the valve spring/delrin/acme combo sounds like it'd be eating the delrin fast ( like only hours till the spring no longer had anything to push on )
just a more irritating shaft
Trying to do it without changing the mill at all (or as little as possible), otherwise we might as well just do a ballscrew setup
Might try it with 2x metal acme nuts and see what the friction is like
ok, try a brass nut, split it and use die springs between and dowel pins to keep alligned. it'll take force and last
you can but acme brass nuts
(or learn to cast babbit ;)
cast what now?
babbit = ?
low melting temp bearing material
Heh i am pondering the practicalities of casting a bed for a bigass gantry mill
cast iron is still pretty much the best stuff to make mills out of
think carbon fiber would be any good?
its plenty stiff and has ~0 thermal expansion
Valen: 18V 21A (heatsinked) but unfortunately has no internal current limit: http://www.pololu.com/catalog/product/755
bah current limits are for pussies
cheap carbon fibre? ;)
I have a source for it ;->
the good stuff too
maybe concrete with embedded rail on top, just machine the little bit o steel
aerospace stuff thats past its "used by date"
thermal expansion issues would probably be the killer with that
i just left B&Q ( taiwan DIY home store) got PVC pipe to make shipping container for my carbon fishing rod
1 meter long in sections (5m total ) cant take on plane.. too dangerous
and once you install the power cap and connectors as shown I dunno how you heatsink the thing .. I guess you would solder everything to the bottom and then place the top against the heatsink
I have no experience with this controller, just something I saw on the internets
if it comes to it i'll just make one
the mesa boards have the right output i think?
they have all sorts of outputs
otherwise i'll need some glue to turn fets on and off at the right PWM from the card
I think pwm + direction is one of the choices
jepler: that board made for electric bicycles?
(all the abttery talk )
tomp3: not sure what it's intended for
is there one with 4X PWM chanels + deadtime?
tomp3: robots maybe
might work for robots
you mean one for each switch in an h-bridge? no, I don't think so.
dang, its a shame, a whole FPGA sitting there begging to be used too lol
it's made for little robots
they are a hobby outfit
it's more a matter of pin count, I suspect.
one connector = 24 I/O points. mesa does 4 position-control differential servos on one connector, or 6 pins per motor: ABZ PWM DIR ENABLE
[14:23:44] <Valen> http://www.robotpower.com/catalog/#simple-h
i know works for $80
the baby mesa cards have 70 odd IO ports dont they?
mix up some logic chips to convert PWM + direction to the correct drive type
Or i'll just use a bunch of the "fets" on it
they are brilliant
don't parallel too well though
that one has higher voltage and current specs, better provision for cooling, plus it sounds like you've used it before -- that's got to be the better idea even if it costs a bit more
I've used stuff from them before
plus schematic, that's nice
heh i'm soon to become their service agent in Australia ;-.
not much of a discount though :-<
[14:31:50] <Valen> http://www.robotpower.com/products/firecracker/
is the next step up
"coming doon" though
Anyone know a way to check my Servo To Go ISA Bus card is communicating with HAL??
if the hal_stg driver loads, it is
ok cool, just wanted to make sure
check dmesg after it loads - there will be some information there about what kind of card it found.
check it in the hal shell or in the main terminal?
in a terminal type dmesg
kk one sec
Im excited, I should have my mill powered up on monday to test out emc2 and get my feet wet
so it showed up correctly in dmesg?
good, you're on your way then.
yep, just got to finsh a few wiring issues, then I'm going to test spindel and baxis functions
still need to wire in the limit switchs for over travel so im going to hold off on the xyz
is it me or has emc users started to increase at an exp rate?
I've been gaining weight at an exponential rate, yes. Even Since I got married.
I have actually reversed that trend
down to 210 so far.

what browser is that?
guess it doesn't know how to do "margin-right:201px" :(
looks like it wraps in the right place OR at the width of the images below, whichever is greater
I think it's the table with the pics.. right
* alex_joni changes that
cradek: better now?
better for me, but still has the problem at some width I guess
youtube is really slow for me :/

Does anyone know if there is any possibility of using a stepper motor with a uln2003 on a serial port with linuxcnc?
if you mean parallel port, yes
emc2's stepgen can generate lots of formats of step output that are suitable for driving motor windings
serport? heck no.
[18:59:46] <cradek> http://www.linuxcnc.org/docs/2.3/html/man/man9/stepgen.9.html
No possiblity of using a de-9 serial port rather than a de-25 parallal port?
in what way would you expect to use serial to communicate with a uln2003?
No clue, thats why im asking :)
ok, then the answer is no
