oh, and of course there's the problem of completing things like -i <*.ini>
welcome to our planet
who you calling an earthling?
I don't like this planet, it's too cold
quite a change of weather today
do you two have the same weather?
the snow we had melted overnight, and it was raining this morning - maybe 40 degrees or higher
heh - actually 27deg here..
usually I get his weather a day later or thereabouts
we (Cleveland OH) had high 40s, maybe even 50 yesterday, high 20s today
well, then it went down 20 degrees or more in 2 hours, and the rain turned into snowfall
i'm in boulder, colorado - we had our first real snow a few days ago
it's now around 20 here, and we're supposed to get a storm, maybe a noreaster, around Friday
one more day of work, then off till Jan 5
* jmkasunich does a happy dance
we expect great things, jmk
very nice :)
gotta use up that vacation or lose it, huh?
more power to you then :)
That should be just enough time to get your 5 axis gantry running...
*made and running
definition of "mixed feelings" - getting a nice sized order, and then realizing that I'll probably spend a chunk of my vacation working on it
more carb stuff?
MAX_VELOCITY = 20 :)
a while back I made some test jigs for a couple labs
then another lab wanted some, and either I was too expensive, too slow, or something, so they had a third party make them
what do you charge for machining? if you dont mind
the result was horrible - they should take that guy's machining license away
so they're paying me to repair them
seb_kuzminsky: I don't really have a specific rate, and don't do normal machining - I'd have a very hard time competing on piecework type stuff
in this case, I helped to design a jig that wound up in some ansi or other standard
so I'm the leading supplier of jigs
I think the world marked for such jigs is about 15, and I've made about 12 over the last 5 years
let's hope some break :)
my jigs are the standard cause they are build like a BSH
uh-oh, there's two of them!
that just reminded me of something my ex-wife's grandmother said about her son (her father): If he was twins I would have drowned one of them"
hey seb_kuzminsky, if we had another garage we could fork again!
"her son (her father)" - that makes a lot of sense doesn't it?
jmkasunich: a complicated relationship, obviuously
terrible accident with a time machine
read the short story "By His Bootstraps" for a good chuckle
I think it's by Heinlein, but it could be Asimov
did you read "the man who folded himself"?
I think I've read that (bootstraps)
forget the author
no, I don't think so
[03:34:37] <jmkasunich> http://en.wikipedia.org/wiki/The_Man_Who_Folded_Himself
the net knows all
yep. just read that page :)
that page also confirms that bootstraps is heinlein
I'm on to the description of "All You Zombies" now :)
heh, I've read that one, although I didn't remember the title
strangely, I missed that one
and I've read a lot of Heinlein
I think it read it in an anthology of time-travel stories, rather than in an Heinlein collection
I probably have one or two anthologies of that sort - I'll have to look for it
then again, I know how it ends now :)
have i mentioned yet today that i like halscope?
hmmm. let me check the logs
no, I don't think so
how do i love thee? let me count the log entries
appropos time-travel stories: marooned in realtime
and of course "The Peace War", which comes before it
and there's a short story about the policeman as well (can't remember his name or the name of the story :) )
possibly my favourite short novels of all time
there's a book with all 3 called "Across Realtime"
yeah, they're excellent
not time travel, but have you read "Ender's Game"?
did you read A Fire Upon the Deep and Deepness in the Sky too?
i read enders game a while ago - definately one of Card's best
yeah. I think it's one of the top 5 books of all time actually
it's a short set in the Zones of Thought universe, he's rewriting it as a sequel to AFUtD
I guess I should start going to book stores again
but it's probably better for my finances if I don't :)
and your emc2 productivity ;-)
nah, nothing can help that ;)
grr, "current" is a symbol in the linux kernel sources
so you can't name anything that
yep, the current task
hmmm... "current_task", what a great name!
they should have just called it "c"
but that's the language, silly
any pythons about?
looking for the equivalent of break
for line in file:
if stuff found:
done with file, don't want to process the rest
how about break?
looks like that works
just like C: http://www.network-theory.co.uk/docs/pytut/breakandcontinueStatements.html
well, I'm now autogenerating all the input files for the synthesis step
time to actually invoke the tool from python and see what blows up
cool - seems to have worked
I only ran the synthesis step, but the remaining steps are more of the same
need to put a bit of error handling in there
interesting - when I ctrl-C the synthesis tool, my python resumes control, and prints an error message, which winds up BEFORE the last several lines of output from the synthesis tool
had me scratching my head for a minute....
EMC: 03jmkasunich 07TRUNK * 10emc2/src/hal/drivers/mesa-hostmot2/firmware/src/ (4 files): first steps toward automating FPGA firmware builds
SWPadnos: jepler: if you get a chance, could you cvs up and then try "spec2bit.py SVST8_4_5i20.spec" on your systems?
I'm interested in both linux and doze results, with various versions of the xilinx toolchain
it'll be a little while. different PCs for CVS, ISE, and EMC :)
don't feel any need to do it tonight, I'm about to quit anyway
yep. me too. good work there
* seb_kuzminsky kicks CIA-42
ok, i made encoder velocity estimation not be limited to 65 ms, it's now totally up to the user how long to wait for another encoder edge
well, it will be once i make that variable a hal parameter, for now it's hidden inside the driver
pics here again: http://highlab.com/~seb/emc2/
lazy garage_seb get back to work
EMC: 03seb 07TRUNK * 10emc2/src/hal/drivers/mesa-hostmot2/ (TODO encoder.c hostmot2.h):
EMC: Better low-speed encoder velocity estimation.
EMC: The "timeout" for waiting for the next encoder edge is now unconstrained
EMC: by the FPGA's 65 millisecond rollover, though i havent exported this as
EMC: a HAL parameter yet.
EMC: Also: Misc internal cleanups.
can someone change the driver type drop down box in stepconf.glade from Gecko to Gecko G201 as the timing is different on different models
I changed it here but cvs diff did not show it so I assumed that I did not know all I didn't know about it
jmkasunich: it seemed to work on both linux (92i) and windows (10.2); I sent you a little more info in private message
BigJohnT: what file did you change?
I changed the stepconf.glade file and tested it
and to my suprise it worked
EMC: 03bigjohnt 07v2_2_branch * 10emc2/docs/src/config/stepconf.lyx: add info on drive timing
for a reason I can't fathom, redirection in cmd.exe makes xst hang (go for minutes with 0% CPU usage in task manager)
.. for an equally unfathomable reason, it seems to work when using redirection in msys terminal and bash.exe

yes - I was trying to figure out why big<tab> wasn't working until I notice he had quit.
man.. mach3 is one big POS

wow - that is funny. (almost quote worthy)

barak obama - it's not who you know - it's what you know. (TM) What a great idea :)
I figure by next year I should be spelling his name right..
yeah, right :)
skunkworks_: tried actually running it
it's awful, I can't explain why people like it
for once if you push estop on the GUI it unloads the loaded program, so you need to load it again
* alex_joni shudders
you might as well unload the program if, by definition, you will lose position and have to re-reference the machine :)
I mean, it doesn't help, but it doesn't hurt much either
I understand resetting the interpreter, and rewinding it back to the first line
but unloading it is odd imp
heh, cool: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=330252914453
this guy was asking $3000 for this thing before, then he reduced it to $1299 I think, now $750 (but no best offer option)
cradek, do you happen to know the sizes of allen wrench needed to get that end cap off or turn the screw on your lathe?
no, but they are all english sizes
ok - so a standard set should have them, no giant ones or anything?
right, a basic english set will have what you need
also take something to pry with - the covers might still be sealed with gasket glue goop
RTV or just the oil of the ages? :)
although probably not the ones on the screws, since you have to open them to crank it off the limit switches
oh, that's annoying
they are/were all sealed with permatex (?)
not sure how much testing you are doing - but be aware the control won't come up without air pressure
that was a bit of a surprise for me
I don't know if JMK will be able to plug it in
ah, one at HGR?
he sure won't have power then
it's still for sale, and at $799 it's probably a good deal if the screws move and it's not too gooey with sludge
what size motors are on yours?
spindle is 2HP, axis motors are the originals, I don't know their ratings
they are about 4" diameter I think - they seem small for how powerful they are
I bet the motors in that "Unique Writing machine" I linked to would do it
they're 200W Yaskawa AC servos
I can't even begin to budge the 50W ones I have, so the 100;
100's should work nicely (if the motors on the lathe are bad)
the motor mounts have a complex oilproof setup sealed with O rings - you will have to do a lot of tedious reengineering to change the motors.
is the mounting complexity on the motor or the machine? (ie, is it a standard motor that attaches to a complex mount)
one seal is a plate with a circular hole with an internal O ring that seals around the body of the motor itself
also, the wiring comes out the shaft end of the motor so it's all inside the machine
err I think
no, maybe not
I don't remember how the wires go, but it ends up inside
do they look like standard NEMA 42's ?
I don't know - they're round, they have a square flange with four holes
oh, hmmm. if there's a bug complex mount they may need a longer shaft than normal
ok, flange type was my next question :)
I bet the shaft sticks out about 2"
ok, that's normal
it should look familiar: http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=21-211-041
pulley with one split dowel pin
oh interesting - they use a dowel pin instead of a key?
or as a key
yes pretty sure it's only a pin
iirc, shaft is plain with a hole through it
people say that keyways are bad for CNC because of the frequent reversals. I wonder if that's meant to absorb a little bit of that load
make sure the collet closer is on it ... would suck to have to find one I bet
ok, I'll let JMK know :)
if so, it doesn't work -- on Z, I had to replace the pin, as it let the pulley turn a bit on the shaft
it may have worked for longer than a key, but who knows
the bridgeport clamping collet thing seems very good to me - but complex
actually, there's a chuck on this one (from the photo)
yeah that's nice
hmmmm, strangely I think it's not screwed onto the nose
maybe it's a 5C mount chuck?? seems too big for that though.
I can't see it well enough to tell if it's an air chuck, but I suspect it isn't (because the diameter of the "base" of the chuck seems too small)
"pay no attention to the forklift behind the curtain"
oh hmm. that could be an air-actuated chuck. the actuator would have to fit within the 5C diameter anyway
are you talking about this http://www.electronicsam.com/images/KandT/servostart/smallservo.JPG
not that I know of :)
is that from an HNC?
I think that is a servo from an hnc
I may have been confused about what you guys where talking about earlier.
[20:07:58] <SWPadnos> http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=21-211-041
and this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=330252914453
wondering if the small AC servos would fit on the HNC
probably not, though they may be powerful/fast enough to use
yes sam's motor looks about right
ok, so the flange is set back like that?
yeah I think it's just like that
(it's been a few months since I had one out...)
good for you :)
the wires do come out the front, and I recall the brushes couldn't be replaced without completely taking the motor out
ick, the centroid lathe pendant assumes tool on top/back - it would be backward for this machine
oh. they mention that the servos are 17 in-lb
SWPadnos: I'm free!
and planning an HGR trip tomorrow
