Ziegler: Ok, so what exactly isn't workign well with the design, not stiff enough?
Ziegler: and in which axis'
and the rotary tool is whimpy
but that can be changed easily
does that tool have an unscrewable finguard near the tip?
I was trying to plundge through a sheet of copper flashing and was not able to
yes it does
why do you ask?
use something like an 'L' brakcet, but make it dense, like out of 1/2" MDf to thick metal, like 1/8" or thicker.
that'll make the tip "rigid", then just brakcet the back end to keep from wobbling.
I think my movment comes from the box around my x rails
are those Y tubes, solid?
It may need some side plates to keep from twisting
they are 1.5" EMT
have you checked to see if everything is squared up still?
ahh... some if it is now out of square :-\
the Y frame?
the box around the x rails (the rails on the gantry)
the stuff under the grey top?
those rails are still good
everything from the grey table down seems to be ok still
everything hanging in the air has problems
the z rails supports are sagging a bit now
ok, then just add another piece of MDF (~8" tall) to the back of the Y frame to stiffen it up. Might even use 8" long angle iron
the angle iron is a good idea
great idea actually
Well, the angle iron is to bolt the new backer plate MDF to the existing Y frame, as screwing MDF to MDF at right-angles is a bad idea.
they don't have to even be fancy, could be something thing and cheap.
I actually have some scrap aluminum angle laying around
that will do too
yeah, no doubt. Drill oversized holes so you'll be able to adjust later on if you need to.
there's always 2" fender washers if you DO need them =)
The kicker in all this...
I have access to a 4 axis mil in the shop, and a cnc'd lathe too
hey, better than what I have access to =)
well except my machine NOW that is.
I drool over some of those machine that people have made using that extruded t-slot aluminum
you mena 20/20?
that the same thing?
My "goal" with this machine... was to make it "good enough" to cut out patterns, so that I could cast the parts for the next machine from aluminum or cast iron
I think it may be good enough, but it will be slow going. I could cut out the patterns by hand faster
(anyone know off hand where are the ttfs are located in ubuntu??)
(true type fonts)
they even have a deflection calculator online too
good old locate to the rescue
search ebay too, they sell rem's and minor mfg defect pieces up there as well
scratch and dents good for me
one thing, forget their "linear bearings" they're crap for CNC purposes.
[01:14:36] <JymmmmEMC> http://k2cnc.com/
Ok, back in 90
Good to know about the bearings... that was my next question
Can one use loops in emc's ngc files? I would like to drill a matrix of 10x10 holes, so a conditional loop would be nice
Guest127 is now known as skunkworks
everyone bail out?
im getting ready too
I ment back at FEST
yeah I think so
we went for dinner, and are now back for the final pack up and load cars
I was wondering if the webcam was gone and the server is just reposting the same old last frame...
the webcam will probably run for another hour or so
jmkasunich: are the videos up?
working on it now
can anyone try running a program for me ?
sounds like you all got alot done! - many thanks from all of us on the sidelines.
[01:55:25] <anonimasu> http://www.pastebin.ca/571238
*unsure if it works*
anonimasu: you need to install linux on your computer ;)
ditch the "R" word in G2/G3 usage and use I and J values.
skunkworks: you need to write a cam program for linux
skunkworks: will do
I don't have the skills ;)
I am just a emc fan boy
so, does that code work?
I tried to buy some "obsolete" source code... but the owner was not in the mood to sell.
old DOS based CAD/CAM
figured it might be the easist to port
* skunkworks is running xp right now
what is your question - I can try running it thru a graphic sim?
hm, will it run on emc..
[02:07:03] <Skullworks-PGAB> http://www.ncplot.com/ncplotfree/ncplotfree.htm
does that run everything emc will?
it is a graphic test backplotter
Well, That's kind of pointless..
your code might have some issues
I know how the toolpath looks, but the question is if it works with emc..
and you might need to ditch the M30 %
Skullworks-PGAB, do you know if g-code supports loops? I would like to drill a matrix of 10x10 holes, so a conditional loop would be nice
Yes it does
also your first G1 line has a F0.
skunkworks: nice :)
that will stop everything
[02:11:52] <skunkworks> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Oword
anonimasu: autocomplete problems?
Other than what is listed EMC should have no problem with it
did you mean skunkworks?
videos posted http://linuxcnc.org/compile_farm/festcam.shtml
hey - I closed the page any time I was not around...
the f0 is odd.
jmkasunich: the links don't seem to be working...
I found the problem 0.001 plunge feedrate
looks like I need to go outside and try this.
anonimasu: - that looks like a Mastercam Post generated file...
jmkasunich: the festcam video still works - just not the tapping ones.
skunkworks: yep ;)
I hope this works.
I have MC9 and all the training vids - and not a clue how to use it or the time to try and learn.
so when is the canned stock removal cycles going to be available for the lathes?
[02:25:01] <anonimasu> http://www.pastebin.ca/571281
I had the permissions set wrong, try the videos now
Skullworks-PGAB: it's very easy to use
Skullworks-PGAB: though mcx.. is much easier
jmkasunich: perfect :) thank you
does that look better?
I still use my old CAD/CAM - I'm fast with it. - when needed I use my newer version for 3D or other stuff the old one can't do
webcam going offline....
I'll post the final movie when I get home
does your machine have a 4th axis?
hm, looks like my arcs are messed up
and is your spindle cnc controlled?
if your INI file does not have a forth - EMC might not like the A0. - don't know thats just a guess
I/J - are they set to inc values?
they need to be.
all I can set it to is Unsigned incremental
hmm - needs to be signed incrimental
though NCPlot shows it as crap..
Hurco wanted abs - fanuc wants Inc (signed) and so does EMC
mpfan is the post im modifying
dosent look like they have that
you have a post for 0m or 0mc?
Haas is very simular
I have a generic fanuc..
that should work
So cradek is going to be sitting there until next year ;)
at least we know where we can find him.
still the same thing
and the top of jmkasunich's head
Skullworks-PGAB: it only does inc
but thoose toolpaths end up ok in the preview..
it kicks hand-coding.
sorry - I don't use NCPlot much - the code I get from my old cad/cam almost always was good to go - no need to hunt down stuff in a graphic backplotter
I used it mainly to test code supplied by customers
im writing a post :)
hopefully this works
[03:06:45] <skunkworks> http://www.youtube.com/watch?v=JCEwlfJj__A
and a bottle of Cpt Morgans Spiced rum...
hum, EMC2 is very close to Einstein's e=mc2 coincidence? I think not ;)
sssssh he's here
anyone still awake?
I just woke up :)
and I just came back
what do you guys think of this for an controller enclosure? http://www.electronicsurplus.com/objects/catalog/product/image/img69165.jpg
It's 19" wide and 10" tall
looks like std 19" rackmount
it is, for cards the desc says
19" includes the mounting tabs
I'm going to catch some ZZZZzzzz I have to wrestle the iron in the morning.
who is left at the cnc workshop, he looks bored
The-Ball: That's cradek - the last picture before the webcam was disconnceted.
Rugludallur: Are you there?
jtr, ah ok. I have been working on a "cage" for my mill today, so that i can use liquid when milling: http://wigen.net/workshop/zx30/IMG_0236.JPG
the hal_joystick device works well with xbox joypad hacked to a stock usb cable.
but the big "+" button isnt in the list of hal items. the left A& right trigger pots are listed,
as are the 2 joy btns , the X Y A B btns, the B & W btn pair, and the 'Back' & 'Start' btns are all listed and ok.
It just seems this big central "+" joybtn was left out. Normal?
here's the hal show pin joystick result http://pastebin.ca/571942
xemet: is there a way to null the analog outputs of the joypad? they wake up non-zero (or -1 ). if used as jogging device, this would 'drift'
tomp: for joystick devices, the program "jscal" (from package "joystick") can calibrate joysticks interactively or from previous calibration data.
jepler: wicked! thanks!
tomp: the problem some devices have when they power up with the joystick non-centered is tougher and maybe unsolvable
jepler: unscrewing the case, hoping to find a pot to rewire ;)
tomp: in hal_input there are "offset"s which can be used to set the device center -- I don't think hal_joystick does
tomp: no, I mean that if you hold the stick on the right while plugging the joystick in, the internal calibration routine of the joystick may call that far right position "center"
I don't know if this affects the xpod controller but it happens on the wii "nunchuck" controller
jepler: will play and see if holding it matters. tho i'm just usin git for cheapo analog input ( will hack a live +/- 1V signal into it if possible )
jepler: thanks for all the hard work at the fest. you guys got a lot of important stuff done.
tomp: thanks -- we kept busy, between telling people about emc ("how much does a license cost" was a question we got asked), adding new features to the software, and improving the configuration on the mazak
it was one of those weeks that went by in a flash
looks like Roland swapped the mazaks, we worked on the left one before, and the right one was just storage.
tomp: both were moved around in the shop .. we were in the area that was behind the mazaks last year, with the emc mazak in the south west corner
last year and I assume the year before those areas were just cluttered with junk
it looks like ( halscope ) the LSB of the joypad's driver is near 8mV, so i figger that's 1V/127 or .0078125V ( now i have a guesstimate of the bit to volt relationship ;)
8 bits, bipolar output , +/- 127 units spanning analog value of -1.0000 thru +1.0000
joystick package calibrated the joypad very well using 'jscal /dev/input/js0 -c', tho 'jstest --blah /dev/input.js0' always segfaults. Also jscal finds the missing "+" device tho it's integer, not float ( -1,0,1)
jepler, did you meet any "if it doesn't cost anything, it can't be any good" people?
(7:02:33 AM) jepler: . . . it happens on the wii "nunchuck" controller. . . - Thats what we need, a youtude vid of someone jogging with a wii ( just for giggles).
JymmmmEMC, bought those geckos yet?
robin_sz: Nah, got some Parke OEM750's coming though.
and a PSU?
Already have that 48VDC@5.6A switching PS + I have 3900uF@300V caps
robin_sz: what do you mean by "sorted"?
"you hove your problems all sorted out then"
Ah, well the drives are still in transit, so we'll see =)
I thought fest was over? I see one lone guy on the cam still
there was a cam?
[17:55:04] <JymmmmEMC> http://linuxcnc.org/compile_farm/festcam.shtml
I did find the website for the cnc workshop thing
but it was too difficult to get in
$10 for 4 cap clamps, such a waste of shipping charge.
actually, from what I saw of the first few pages, the CNC workshop website probably qualifies for my "worst site ive seen in a while" award
Eh, some do web well, others don't.
[18:02:07] <robin_sz> http://www.cnc-workshop.com/join.asp
# this one
I've seen much worse.... at least there isn't any <BLINK> tags
or blue text on a black background.
well, it wasnt the design that was bad
it was the "so, whats this CNC workshop thing all about then" aspect .. there is absolutely zero clue
apparently to find out whats going on etc you have to register, give youe email addy so they can spam you, you mothers maiden name, home town, dat of birth, copy of driving licence etc
seemed a bit OTT security before being able to visit the site to me
[18:08:05] <JymmmmEMC> http://www.cnc-workshop.com/info.asp
Yeah, I kinda see what you mean. Not even any teasers so to speak
Sorry, I take that back.... there's the <BLINK> tag
ahh, thers the info page, how did you find that?
from web root clicked on "For the Web Site Directory - Click Here"
ahh, didn;t see that, lost in the graqphics
I probably would have never clicked that link unless you had said something about it.
maybe it will be better next year
[18:17:28] <DanielFalck> http://www.artsoftcontrols.com/forum/index.php?topic=3418.0
mach3 point of view.....of cnc workshop
What do you think of this for an enclosure for the new controller? https://www.electronicsurplus.com/commerce/ccp69165-19inch-rack-for-cards---new-10inch-hi-10897327-129704.htm
nice price for rack equipment
it's just a card cage, but I thought I could toss an al plate on the back, and plexiglass on the front
JymmmmEMC, thats called a verorack
wow that must be the only thing they have for sale. Every time I click on a category on the left, I get a 'Sorry ! Document not found' message : )
bob campbells psu/geco/interface box looks neat
DanielFalck, yeah, as you say, slightly Mach3 centric ... they don't seem to mention the EMC talk at all
I presume the big mazak is now all sorted and working, I saw the rigid tapping thing ...
much else left to do, or is it now all put to bed?
maybe. they have tool change working too.
robin_sz: I REALLY can't tell, but does that cage break down into it's pieces?
JymmmmEMC, dunno, not an issue.
I've bee planning on using an old gutted PC case, but I'm sorta chicken to mount an 120VAC outlet to a PC case. I already got a al plate to mount everything on.
DanielFalck, cool, its nice when a plan finally comes together. I hope they managed to demo it doing some nice parts with multi-tools
What I REALLY want is to be able to mount a 1U server mobo and the controller in the same enclosure, but haven't found the right enclsoure for that yet, and can't think of anything to make one properly (except some 6" C channel
LOL.... Do you think this is telling me something? (read the first feature) http://www.hytec-electronics.co.uk/8810.html
JymmmmEMC: arent thosoe damn expensive?
VME stuff are pretty pricey
anonimasu: That last link or the first link?
a 1U mobo would be a really poor choice
robin_sz: Why is that? This does 15500ns max latency?
normally they only support a single PCI card
it's a server mobo, dual nics, and I already have a riser card
actually it's a dual P3 1.2GHz 4GB ram
has anyone got rtai to work on smp yet?
robin_sz: cradek has, but I don't know the full details
I thought there were various problems with dual cpu and rtai
I *THINK* RTAI only uses one cpu, but the rest of the system is full SMP
no need to reboot to utilize the SMP
* robin_sz shrugs
Faraday cge really works, and it wasn't even intentional.
anonimasu: My dust-prrof enclosure is lined with al screen. Can't use a wireless kybd inside it =)
anonimasu: you know what a faraday cage is, right?
anonimasu: well, not everyone does.
we are at freenode afterall ;)
Let's not go there, m'kay =)
Cleaning up actually... getting ready to toss a bulk box on ebay of stuff... 20 twict lock, linear rail (nfc), 10K RPM motor, leather electricians tool belt with drill holster, laser alignment mirror (with outdated calibration sticker), and whatever else I can find to toss in the box =)
up to 70 lbs that is =)
maybe these linear power supplys as well.
im working on some design in sw
designing what? mechanical, electrical, electronics?
16VDC @ 12.5A =)
actually it's some car air duct..
you mean heater/AC or intake?
got a better part to practice 3d stuff on?
I mean one of thoose f-ugly naca ducts..
wth is that?
national something something :D
[20:32:57] <anonimasu> http://www.m-99.co.uk/Car_Bodykits/Bonnet_Air_Vents/naca_vent.jpg
National Advisory Committee for Aeronautics
oh, hood air intake
air intakes in general..
as opposed to heating/ac ducts in a car, which are a PITA
anonimasu: solid works?
SW is nice, but I dont have a clueuse for 3D stuff just yet
not that much atleast..
I also heard that rhino (???) or that family does much better for 3d realistic rendering. THAT part I like
so you could design something and give the client a photorealistic img before even machineg anything.
well, it sucks for making real parts..
it's a 3d modeller not a cad progra
though rhino is good..
they do have a CAM pkg for it as well
but i have never been able to figure out which of their products go together, they have them so segrigated.
I know :)
never tried it though
got a picture of this in a sec..
[20:57:33] <anonimasu> http://imagebin.org/9023
hello folks. I'm getting "Cannot do g1 with zero feed rate" does anyone have any suggestions?
g1 x0 y0 f100?
crap. sorry about that. keyboard malfunction.
all my G01 commands are of the form: G01 X%.% Y%.% F10
oh wait. I found a G01 X%.% Y%.% F0 -- not good.
anonimasu: looks like shit.... where be the flames ????
gotta have flames on a hood scoop =)
anonimasu: other than that, looks good =)
err that's not a hood scoop..
it's a duct..
anonimasu: No, this is a DUCT http://fohn.net/duck-pictures-facts/pekin-duck.jpg
