EMC: 03jepler 07TRUNK * 10emc2/src/ (configure configure.in): improve the end-of-configure text
I thought we'd fixed things so that the unused elements of position were zero'd out
>>> s = emc.stat()
but it looks like we haven't.

hmmm. jepler, I just looked over the configure cnahge from last night, and it looks like there's an extra fi in there
at least, I see a +fi lne, but no removed fi or added if
unless I look a few lines below. nevermind
thanks for checking up on me
heh - no problem ;)
after marking as read the 147 commit messages I missed while traveling, I actually started looking at the 5 new ones
SWPadnos: do you think would I find a Core 2 Duo T7250 (2.0GHz) to be markedly faster than a Pentium M 1500 (for compiling software, etc)?
hmmm. let me think about that
especially with -J<something>
does the T7250 have the 4M cache as well?
this page says 2M
if you can get a T7200 or T7400, that may be better - I think those are 4M cache versions
yeah the next CPU up on this laptop for $50 more is a 4M cache version
oh bizarre: "the 9-cell battery will protrude from the front of the notebook approximately 1", creating a soft-touch wrist-rest."
that's probably worth it, especially for something like compiling
oh. I should fire up one of the "google OS development" boards I got
anyone seen this? over my head http://www.ee.ust.hk/~eeyoyo/thesis.pdf
it has a lot of pages
that is what I thought
I could do without the thanks to Jesus
I didn't see that.. I saw him thinking his wife and kids.
and last, the giver of all talents blah blah blah
maybe I'll go back to shopping for computers or something
jepler: thanks for fixing that already (I am sure I got zeroes when I was testing it)
cradek: you were probably running a 9-axis machine
that reminds me, please contribute the simulated probing configuration to CVS
I don't think I was. I was on max.
hmm. strange how NewEgg has the AMD 2.3 GHz quad-core CPU selling for $30 less than the 2.2GHz quad-core CPU
$269 and $299 respectively
phenom or opteron?
one says AM2 the other says AM2+ (socket).
I haven't quite figured out the AM2 / AM2+ thing, or whether a 1-year-old AM2 motherboard will be able to use one of these CPUs (though it's not listed on the official CPU compatability list for my motherboard)
yeah. I lost track of AMD sockets when the 1207/F/1207+ ... stuff happened
hm, among other interesting information this page lists a "Phenom X3". http://en.wikipedia.org/wiki/Socket_AM2+
I wonder what that would mean
apparently it means triple core. "Phenom triple-core (Toliman)" (model number would start with 7). http://en.wikipedia.org/wiki/AMD_Phenom
oh - DDR2 and DDR3 support, for socket AM3
oh right, I remember reading about those now
if all 4 cores don't work, just sell it as a 3-core chip
I wonder how many dies they can salvage that way
intel's had quad cores on the market first and they don't seem to have decided to do this
I'd probably be a little concerned that the process wasn't right for the chip, and that other cores might fail sooner than expected
Intel's quads are actually two duals slapped together, so they wouldn't put a defective dual into a quad package
oh, I see
man -- I want to reward Dell for offering systems without Windows preinstalled and at a slight savings, but they are missing some options (e.g., you can't choose bluetooth in D830N (freedos) but you can in D830 (XP/Vista)) and at least with their promotions today the $40 savings you get for FreeDOS vs XP Home is probably eaten up by the Free Shipping on the XP system.
but you don't need a new laptop...
I keep forgetting that
aluminum sure is expensive.
only if you buy it. How is the max coming? I suppose the shop is taking away from that :)
and work, eating and sleeping..
other than buying it I can only think of one way to get aluminum...
max is coming along fine. I got the second rotary (C) assembled last night
without a surface grinder, which is what I actually needed
next purchase :)
I would think stuart would have an extra ;)
he'd let me use his. too bad about the 10 hours of driving though.
with the price of gasoline, it doesn't take many trips to equal the cost of your own grinder
plus the aggravation :)
I am sure you could get a inexpensive one from enco or the lik
This is how mach does rigid tapping.. :p http://www.hossmachine.com/Videos9.html#videos53&54
but, he's doing "peck tapping"
(he should get some better taps instead)
he said he stalled it once so far - so he added more pecking cycles
a thru tap in 1/2 aluminum should take about 3 seconds :-)
that's about the same as how EMC2 does rigid tapping
except for the fact that he's keeping the spindle load low enough so it doesn't slow down :)
this is actually a pretty clever hack he's got going
SWPadnos: no, he's got his spindle hooked to a stepper configured as the A axis
oh, I didn't notice that part
he must pull the belt off to do regular machining
ok. I noticed the belt, but didn't think further than "that's a strange arangement"
it does look like hand tapping might be faster
yeah but this is going to be much more upright
this is what someone would have had to do with emc a few years ago...
but we can make fun of it now.. ;)
I still think it's pretty clever considering what he's working with
yes - we had discussed this at the cnc workshop.
neat little tool holders - I wonder if they are tormach?
did you see his tool changeer?
he has turned that little mill into a monster.
[18:56:48] <skunkworks_> http://www.cnczone.com/forums/showthread.php?t=30385
must be air powered somehow?
I think he used belvel springs to clamp it - air cylinder to unclamp.
I can think of all sorts of designs for power drawbars right up until I realize the spindle still has to turn
[19:00:00] <skunkworks_> http://www.cnczone.com/forums/showthread.php?t=43651
that is his toolchanger thread
jeez his Z is slow
I would tell him he could use my drill press and tapping head...
yes. (I was thinking the same thing)
(having him use your drill press and tapping head)
I did a bunch of 1/2-13 holes that way. it's **fast**
I just found why it's so slow: http://www.cnczone.com/forums/attachment.php?attachmentid=29635&d=1168883992
"FET-3/Dynamo kit($329) from stepperworld.com"
it's a dumb unipolar L/R drive with expensive transistors?
it might have step/dir circuitry (probably PICs)
with his 10? pitch ballscrews and those big steppers, I couldn't figure out why it was so slow...
those black package ICs look like they must be power, because they have the funny double pins at the center. http://www.stepperworld.com/images/fet3Pic.jpg
the yellow/orange ICs -- dunno what they are
[19:37:07] <cradek> http://www.cnczone.com/forums/attachment.php?attachmentid=31317&d=1171070322
wow look at his pendant!
but from the silkscreen text it does look like it takes step/direction
the yellow/orange ones look like resistor packs to me
yes the yellow are definitely resistors
for $329 you could almost buy three geckos. what a joke.
I think the $329 kit includes motors
but this is so simple - it just plugs right into the parallel port
yep, 190 oz-in
heh, and a power supply
on the sp3 you can see that the funny power chips are ucn8048 (not 100% sure of the digits) http://www.stepperworld.com/images/SP3pic.jpg
that looks like 5804B
UCN5804B description : ALLEGRO - BiMOS II UNIPOLAR STEPPER-MOTOR TRANSLATOR/DRIVER
and some nice fast 1n4001 diodes I'm sure
I played a bit with zenbot last night. I found that 1/4 stepping works a little better than 1/2 stepping, but 1/8 stepping still works for crap.
I dunno why that would be
in this thread he does say it's R8 so those are probably tormach or similar
(R8 seems so small for use in a full sized mill)
jepler: problem with accent in checklinks
python ../docs/src/checklinks.py ../docs/html/gcode_fr.html ../docs/html/gcode_main_fr.html
Anchors used in gcode_fr.html but not defined in gcode_main_fr.html:
make: [checkref_fr] Erreur 1 (ignorée)
all these links are correct but with accents
I have to remove these accents ? or you can update the script ?
do the links work when you use a browser?
It's just messages, but they are ignored
jepler: I don't like all these warning :)
I'll look into it
jepler: tnak you
yes it's a problem of encoding
I'm not sure how to untangle it but I'll keep working
jepler: This is not very important!
