the fact that all the houses were 3/4 scale, and had hastily bricked missing walls etc didn't help

Um, she needs a boob job (or at least a push up) http://www.wallpaperbase.com/wallpapers/celebs/jewelstaite/jewel_staite_3.jpg
Jymmm: let's not get started on the things you need
(is she an emc user?)
TiN coated tools, is that good for metals?
Yeah, she's fabricating bra inserts (I hope)
LOL, this is pretty good... http://www.collegehumor.com/video%3A1938053
cradek: I doubt that Jewel Staite is an EMC user, but I'm sure Kaylee Frye uses EMC47 to make replacement parts for the anti-gravity drive.
frallzor: I can't find a recommendation for TiN on Al in MH
nm, the specs said Alu was fine it seems
some data on feeds and speeds
oh nm Ill just countersink some of the holes by hand and skip the ones not needed as it turned out
dont you be hating kayley
she be sexeh and if you don't like it she'll brain you with a wrench
cocatoo is an exotic bird now?
Valen: In the US, yes. In AU, a pest as I understand it

* alex_chally spent all day in measurement hell
my screws need to be aligned within .002" over 16" horizontally and vertically
and I am boring the nut holder out to fit the ball nut, and setting up that square to it is proving slightly difficult
.002 over 16": don't breathe on it
cradek, yeah I figure no matter what I do I am going to have to shim it
as the nicest indicator I have is only graduated every .0005"
so reading between the lines, .00025 +- a bit
so aligned to what within .002? I don't see what you're doing
cradek, I believe aial missalignment
is the issue
hmm, that does not make a lot of sense though
the y axis is designed to float on one end, it seems it would droop more then that
(gently suggesting) maybe you are in measurement hell because you don't understand the problem well enough?
cradek, well I am in measurment hell because I want the alignment to be at the limits of my measuring equipment, which is well within the capabilities of the machine
cradek, well that and the horrifying thought that I might fuck it up. There are no replacement parts to be had and I don't feel like fixing anything
not quite a pest but fuckin noisy lol
why do the screws need to be aligned so precisley?
Valen, because that is what it says in the little one page info sheet that came with them :)
i mean, that is .00125" per"
which is not actually insane, just kinda difficult
i missed a 0
aligned to what is the question
oh, the ways
of the axis in question
well at least that's easy to measure then - you hook your indicator to the slidy bit
oh yes, it is easy to measure the screw
assuming it slides in a straight line of course
the problem is squaring the Y axis nut mount for the boring operation that I need t od o
can't you test that squareness with an indicator in the spindle?
cradek, yes, but there are multiple critical surfaces to possibly measure from and iwas getting discrepant measurements
[02:49:51] <alex_chally> http://www.flickr.com/photos/33383121@N04/4701046799/
that is the part that I am cutting
I mounted it to an angle plate, and indicated in the bore, but then when I tested against the angle plate I was not square any more
so then the question is was this an acceptable amount of missalignment from the factory for the acme threaded nut, or is it a factor that was accounted for in the hand scraping and fitting of that part to the saddle, or a warp in my angle plate (old as hell at a school, who knows who has dropped it)
ok I see what you're up against now :-)
if it is an acceptable amount of error for the ACME thread nut, then I should bore it square to the angle plate (and thus the mounting surface of the holder)
if it is something that was scraped in, I should bore square to the ohle
i guess I could put my saddle and table back on the machine, put an indicator on the table and run it across the mounting point and check for relative squareness to the rest of the machine
too bad you can't line bore it somehow with it actually installed on the table
if the mount point is parallel to the table, then I should make my bore square to the angle plate
if it is not, I should align with the bore
yeah I think I agree
but don't trust any angle plate without checking it of course
fuck, that means putting the table back on
some are just for mounting stuff, not squareness
it is an adjustable plate, I had to square it
really nice one
old cast iron, hand scraped
made in detroit, could not see a mfgr
why do you have only one chance at this? you're not cutting that original piece are you?
and it is not a common mill
why not make the whole piece?
so if I fuck it up I have to ... do that
I need to take a trip to HGR
anybody still awake?
alex_chally: where are you located? if you draw it up and send me a .dwg file, i could mill you one out of <insert material here>

foxtrot is now known as foxtroll
foxtroll is now known as foxtrot
foxtrot: how are things?
elmo40, pretty good, I am trimming my Z axis wood to lower its weight
and I upped the current on my motor driver for Z
seems to have taken care of the torque issues
im still having a lot of trouble consistently milling where I want to
im like 33% that I actually hit the material with the dremel
the other 33% i miss it completely
the other 33% i go like an inch into it
im extending my rails and adjusting my gantry outwards another 6" or so
to get my workable area above the current 8.5"x3.5"
i think I can get to about 12"x10", its just going to be ugly with long rails sticking out the X and Y
for the most part, weight (in the right areas...) equals rigidity. For the Z, though, it can cause missed steps.
i've got a big piece of MDF the entire length of my X axis, and 4 bearings on it, so i think its a little overkill
no such thing as overkill ;)
hehe in machining thats definitely true :)
the more I mess with this machine though, the more I want to build a new, bigger, better one
fixed gantrys are a pain in the ass
I really want a moving gantry
with my stage/surface fixed
instead of the current way where I have X&Y plates moving all over the place
i wish I could find some simple plans for the mechanical aspect of something like that
get larger motors before you extend things too far.

does it make a nice circle? did you manage to tune the x and y axis properly?
Jymmm: ahh, good times
but i was thinking of a 427 3x2 barrel
is it just me, or does the older Diamondville have Better specs the the more recent Pineview? http://ark.intel.com/Compare.aspx?ids=35641,43098,
[05:38:07] <Jymmm> http://media.photobucket.com/image/351%20blower/johngipson/superchargerpics002.jpg
elmo40, I made a circle but it looks a little off
you need a super charger on a mustang... the only way to make it roll. :-P
Ive got relatively powerful motors, I was planning to build a bigger machine and use these same motors (nema17, 24v, 1.8deg, 2.5A) and just put old crappy salvaged printer motors on this machine
foxtrot: could be many factors.
i dont know what powerful means in regard to that
elmo40: it's just you
nema17 is a mounting standard i think
alex_joni: Find NEMA17 with 230inoz or better
I just wish I could 100% master controlling location and workpiece distances in emc
everyones tried to help me but i just cant comprehend it properly
foxtrot: my tiny nema23's are not enough power for my wee 9" x14" mill...
Jymmm: I was talking about Diamondville vs. Pineview
foxtrot: if your Z is still acting up, it could be missing steps due to weight.
alex_joni: just looks like it.
alex_joni: Sounds like minoe league baseball teams
Jymmm: it is :D
majour league is AMD
less watts consume, almost half the transistors but practically the same 1.6GHz speed
what ma i missing?
alex_joni: Hey, a friend gave me a "portable computer"
elmo40, thats why i was going to trim the wood
"Additionally, TDPs are often specified for families of processors, with the low-end models usually using significantly less power than those at the high end of the family."
foxtrot: do you have the link for your picture?
alex_joni: true. but 1.6 vs 1.66 isnt much of a difference
elmo40: and integrated graphics for the Pineview
but 13W compared to 8W is a lot!
alex_joni: (not this one - I wish) http://www.chassis-plans.com/rugged-portable-lunchbox-computer/mp3x17-3lcd-portable-computer.html
Jymmm: for some values of "portable"
ya, u can carry it :P
That's still awesome =)

Jymmm: portable CNC controller?
now that's an idea for Aram K :P
alex_joni: aram what?
alex_chally, good man
sorry was at the grocery store
im still having trouble with getting my distances right
but i just think its my own stupidity
youve tried to explain it to me
im just not getting it
and still drilling into the board
emc keeps only letting me move like .1" total on my Z axis at times
im just confusing myself
[08:05:33] <alex_chally> http://www.r44sales.com/1992R22BetaforSaleSN2139.html
i want that
foxtrot, when you set the travel for you X axis, did you tell it that you wanted travel in the - direction not the + direction?
what do you mean
i was homeing it all the way to the left (-)
so i was setting travel to 0 to 8.5
foxtrot, in your ini file you specify the limits of your axis in both + and - direction
travel is from -8.5 to 0
not 0 to 8.5
foxtrot, does that answer your question?
ohhh that must be whats wrong for my Z
what should i make the Z travel be
if I want its home to be at the top
and then it to come down
whatever the total travel of your Z axis is, but in the negative direction
i don't know if you do maths, but -|ztravel
questoion, tuing up our mill, I get it fairly close, then i use FF1 to zero out the position error when its running at one speed
thing is when i change the speed the error changes
0 to -6.5 if my Z travel is 6.5?
and then I move it all the way up and press home
you can put home anywhere in your travel btw
we have 0 at the bottom
but "home" at the top (if we used home switches)
well my problem now is getting it to actually make contact with the workpiece
its complicating things because im just using the premade examples
so whats the problem specifically?
user error :)
of course, but what paticular aspect ;-P
well i keep either milling into the air above my workpiece
or drilling through my table
have you touched off?
where should i touch off
your G code specifies heights in it
you need to tell EMC where the 0 in that gcode is
foxtrot, [01:20:17] <foxtrot> 0 to -6.5 if my Z travel is 6.5?
[01:20:25] <foxtrot> and then I move it all the way up and press home
this is correct
or, a correct way to do it
can you pastebin the code?
there is no code just yet
im trying to mill EMC2AXIS
foxtrot, you really should try to just do a square first
and a circle
a LOT more information can be figured about the machine (length reported vs length traveled among other things)
backlash can be calculated
eh its fun to press play and see things work though
and it will be a bit more predictable
can you pastebin the code?
I think its Z is at 0
or just the first bit of it at least
axis was the first thing we ran as well I think ;->
foxtrot, so with the change in the Z axis settings to a negative number, can you get all your axis properly homed?
all the mills I have seen have Z increasing as you go away from the table
well I home it and then I press - to move closer to the table Valen
foxtrot, ok, so let me tell you a little story about a guy we like to call G54
what do the co-ordinates do
foxtrot, G54 is a command that sets what I will call a work co-ordinate system
hi guys! i have been trying to set up stepgen and ive been reprogramming all the files but now im getting an error when i lunch emc2.. it says parport.0.pin-24-out does not exist
foxtrot, a work co-ordinate system allows you to set a new 0 point anywhere you wish, after your machine is homed at it's limits
foxtrot, that would allow you to, for example, have multiple vices set up and to run the same job on each one, or quickly set your tool to run a couple inches above the part in the air so you can test the code for large errors
its also set at the start of most gcode files
as in setting which workspace your in
I think its probably above his pay grade just at the moment
give the guy some success and lets get a pen drawing of axis on a bit of paper ;->
Valen, I was going to help him do a little program :)
and learning g54 makes life less frustrating
foxtrot needs to learn alot of Gcode before he can start using it,
Valen, also it will keep him from crashing in X and Y, as the axis software limits will work
i'd like to do a little program :)
G54 doesn't stop crashes
homing and limits are done in machine units, axis etc is in G54 by default
you need to take explicit action to get into machine units
huh, I was unaware of that
* alex_chally has not actually used EMC that much
everything is done in workplace cordinates
you need a Gsomething Xfoo Yfoo to tell it to go places in machine cords, its mainly used for stuff like tool changers etc aparently
to run the axis program he needs to touch off his Z at the right height, I'm just not sure what plane that is written for
Valen, interesting, all of the comercial controlers I have used make extensive use of having the machine co-ordinate system be seperate from the workplace co-ordinate system
it is seperate
but all G1's etc are done in workplace cords
you can set a workplace to have the same origion as the machine i believe
the emc2axis files initalisation line sets to G54 as i recall
i just don't know what height it does its "cuts" at
foxtrot, I am writing a quick program, what diameter is your cutter?
you mean my tooltip?
if you can pastebin the first 4 lines i can get you running the axis program in a few minutes
foxtrot, you should pastebin that code for valen
[09:02:11] <alex_chally> http://pastebin.com/
I just want to make sure of what height it wants to run at
also the first line is a good thing to explain all about workspaces and the like ;->
djwez, there is no pin 24 on a stadart //port, so there is a mistake in your HAL file
djwez, max output pin is 17
ja so i found out. goign to have to make a new controler board
Valen: the #1 #2 #3 #4 lines?
to be clearer, pins 1 2 3 4 5 6 7 8 9 14 16 and 17 are outputs, and 10 11 12 13 and 15 inputs
first 10 or 20 just to make sure
assuming you can copy and paste it
i cant, that machine doesnt have net access
so this might take a while
it must be on the interweb somewhere
whats its name exactly?
ok i didnt look there lol
why no net?
ok the cutting plane is at 0
so the easy way is to jog your machine down to where you want to start the start of the E
its a desktop and i only have wireless
so put the tool on the point where you want the cut to start
then select X and press touch off
do the same for Y and Z
the cone should be at the same point in the view in axis then
jog up away from the part
set the feed override to like 5%
then run it
THAT FEEDOVERIDE STEP IS IMPORTANT
oh and put your hand over the estop button
and don't stick your dick in it
for the first try you might want to put the Z an inch above the table
ok im about to try
did it work?
Fox_M|afk is now known as Fox_Muldr
im not sure yet
hmm i set my Z home to -5.0
and then i open emc and jog it to it sproper location (5 inches above table)
and in the upper left corner it shows -4.7 for some reason
and it shows the little white arrow thingas being *below* the EMC2AXIS logo
did youy touch off Z ?
so it's normal the EMC2AXIS preview is not zt the place you want
jog the Z axis to the place you want to mill the EMC2AXIS logo, then touch off Z
you need. to touch off homing is not a requirement
and the preview will be ok with the real world :)
when you touch off, you say to EMC where the 0 of your work is, this as nothing to do with machine home position
setting the machine home is required for axes limits to work.
limits are for pussies ;-)
so, basically, if you don't have home switches, first you jog to the _machine_ 0 (machin home) then home all your axes there
then jog to your work 0 and touch off
it keeps adding .3
its a g54 thing
like i went into stepconf and changed my -5 to 0 to 5 to 0
your homing still or are you zeroing
im trying to home
it will be off by your cordinate offset then
so leave it
well when i do that it says out of range
because its 5.3
set yiu limits large
get it working then when yiu get what all the bbits do use them
where are you ircing from? :)
no I still cant get it to even run the program
i think im about to give up for the night, its 6AM and my brain is starting to hurt
thanks for all the help
im sorry I let you down :(
turn the home and limits off
like make the limits 10000000000

hrmm.. screen froze up
very interesting. The Mazak I work on uses this 'card computer' setup: http://www.datasheetarchive.com/SCE8653711-datasheet.html
only 133MHz ;)
the newer machine, 2005, uses this: http://www.ibase-i.com.tw/ib300.htm
but the thing that i dont understand... i can shut down the computer and STILL run a program. I think the computer is only for the UI. Somewhere else, after you load the gcode into memory, is actually running the machine. I would like to know how they do that.

Jymmm: different expectations, I suppose.
Well, what do you expect since the city and many businesses no long have a fireworks show now.
Just the morters than ppl set off.
in other states, it gets more visual
Well, kick the dumbasses that have nfc and catch the neighborhoof on fire
then they'll allow fireworks again.
So i've blown my driver circuits anyone have any suggestions?
I think maybe uln2003 is no good for driving dc motors?
uln2003 is ok WITHIN its ratings :)
I think maybe something strange happened?
how big of a DC motor are you using?
I was under the impression that any number of darlingtons could be paralleled to give greater current?
only if you do some external power sharing
I was running 7 in parallel which should have covered 3.5A??
don't you need a load balancing resistor?
7 of them
I dont know the motor ratings but looked like it was only drawing 1.1A?
did you have external resistors to power share
otherwise, you get stuff like thermal run away... one of them hogs current... so it gets hotter...which in turn causes it to hog more current...repeat til one pops, then the next one and then the next one....
no external resistors
doesn't matter if one transistor heats up is starts hogging current
[19:50:12] <moop> http://22.214.171.124/ppj/
you cannot parallel bipolars like you did
should show a .jpg of my notes
or you can but the smoke gets out
magic smoke escapes??
I just spent 2 hours and a dollars worth of components, and now i feel like I have been cheated by ebay
I have a search for power sharing resitors on google, thanks for advice
you also failed in your diagram, thats incorrect to reverse the motor current
I always get diodes the wrong way round
its more basic than that, you need an H bridge
H bridge are expensive, i wanted to use uln2003 as I had some in my junk box
but i think an h bridge maybe the way to go
you need to source AND sink current
the uln circuit did work for 5 minutes
and its probably 20 times cheaper than an h bridge circuit
but i guess my circuit idea has major faults or someone would have used it before
* archivist torpedoes Jymmm's SS/Minow
I wondered what happened to the SS Minnow
The Professor made a nuclear reactor, which blew up, acting like a very effective giant flare, so they all got rescued. Except the boat, because it had been previously broken by some attempts to glue it back together.
Skipper Shoes are getting harder and harder to find any more and use to be my favorite leisure shoe
JT-Hardinge, I am beginning to suspect you are a thousand years old
Dawn Wells or Tina Louise..... who would you rather be shipwrecked with? was the old question
close to that I think
or Donna Douglas :)
the professor had built quite a few machines by the end of the series
with bamboo and that one transistor radio that they had
wow i just saw a recent pic of Donna Douglas..... getting my memory eraser out
I think Bob Denver was in a movie where he played a bartender at some tropical bar, and at one point he said to a customer (while holding a couple of coconut-shell cups) "You know, I used to know a guy who could build a nuclear reactor out of a couple of these, but he couldn't fix a 3 foot hole in a boat"
heh I saw that film
anyone else here use Dropbox?
the one on linuxcnc.org?
SWPadnos: I was going to ask you something, but I forgot. So, let me know when you remember, ok?
I think it had to do with LED lighting or power supplies
SWPadnos: No, that was charger circuits. But this was somethign else.
the packages all arrived
cool... the SS minnow is about 5 minutes drive from here....
SWPadnos: Ah, very cool. I completely forgot about them.
good for you :)
SWPadnos: Get your cords?
yep. they're thick :)
SWPadnos: Yeah they are. Good stuff maynard!
at least one of the lenses broke in shipment - oh well
still a good deal
SWPadnos: Really? I even packed in newspaper and everything
so it wouldn't bounce around
I guess good for spare parts then
SWPadnos: He's still happy with them?
I think maybe there was a piece of hardware under the lens in one package
yep, happy they're with them
huh, yoda speak
SWPadnos: Just the grill
SWPadnos: I taped newspaper to each of the lenses
SWPadnos: Musta been the Ooooops Gorillas - could get it replaced under the insurance
oh yeah, they were insured, weren't they
SWPadnos: $100 per package iirc
I got an invoice for $40 also - apparently the shipper number was missing on 4 of the packages, and they charge $10 to look it up (per package - jerks)
SWPadnos: I have the copies right here, the acnt# is on every single one of them.
can you mail those to me?
SWPadnos: As long as Oooooooooops ins't involved
USPS, your favorite :)
Yeah, I can do that
SWPadnos: Just email me the $0.86 =)
I'll DCC it to you right now ;)
yep, that's me
so there :P
maybe later, she's not even home yet
SWPadnos: It's in quotes. That's liek crossing your fingers when you say "I promise"
oh, isn't that funny

has anyone ever tried orocos?
would be interested if anyone has any comparisons between orocos and emc?
moop: orocos is a tookit, not a full blown application like EMC is
i thought emc was a toolkit, programs like axis are the applications built on it?
w00t, new PSU works great
AXIS is just one of many UI's.
moop, my understanding is that EMC is a command line program and AXIS is a gui
I think there is a bit more to it than that. I think there are features only available from code, not the command line, for example.
Anyway, what I have been doing today...
