Hilarious Japanese game show subjects contestants to fear factor challenges. Whats so hilarious about that? The whole contest takes place in a library so while they're getting slapped and being forced to eat an ice cream cone of wasabi they cant scream or cry at all. Brilliant.
where is everyone?
cradek: your image to g-code program, that was mainly for smaller image, right?
like 100x100 pixel image
really? didn't know that
each row of the image is a pass by the tool
I found some cheapish CAM for doze (MeshCam) which does it for any size pictures
but I really find Z-maps bad, if you don't spend a lot of time improving the image
yeah its no good for functional parts
for decorative stuff it's not that cool either
so fenn..what's up?
how's your hexapod :)
talking about tweels in ##electronics
what are those?
dunno where the word came from
the ones with some funny inserts in them?

hmm, did anyone else get disconnects?

IF you have a reliable server somewhere..
hmm, not that I know of (none outside of my lan)
oh, random question, what was the command to check for PCI adresses for external parports?
not lspci but something else
Lerneaen_Hydra_ is now known as Lerneaen_Hydra
this whole article series is pretty interesting (not just part 1): http://www.freesoftwaremagazine.com/articles/free_matter_economy
[11:26:30] <fenn> http://www.freesoftwaremagazine.com/articles/free_matter_economy_2
fenn: do you remember the command to check for pci cards' adresses?
rayh said something about an "real PCI addy in the EMC ini file", any idea of what that is?
or dmesg or less /var/log/messages
are you adding a parport card? you might want to read the wiki page about netmos parport cards
under "supported hardware"
oh, ok. yes I'm adding a new card
oh, according to that it doesn't even need to follow the 0x2XX/0x3XX scheme
well well well,that would explain the "strange" adresses that lspci gave me
woo, dff0 is what it wanted
the strange thing is that cat /proc/ioports didn't show it as parport1
i think /proc wont show anything if there is no kernel module for it
to use two parports, all one does is have both listed in the start of the ini and then configure the pins as you want them?
fenn: oh, ok
yep, that's how i understand it (never done it though)
fenn: is there any graphics card that would be better or worse to have (currently I'm running integrated but I'm having RT-issues). Since I
since i'm going to use the standard drivers anything should work, right?
(well, maybe not a vodoo 2, but I digress)
well pretty much any video card will work
even nvidia/ati cards, if you arent using the binary drivers
fenn: ooh, ok
fenn: what defines what is parport 0 and 1, the order in which they are loaded? hardware?
the order they are loaded
any idea of which card would be best? an "ati rage pro turbo agp" or a "sis 6326 agp"
the cheaper one
I have both in a box in front of me ;)
well get crackin
* fenn flogs Lerneaen_Hydra with an inflatable cat-o-nine tails
I'll take the ati becuase I know it works
* Lerneaen_Hydra gets working

[13:12:01] <giacus> http://www.giacus.org/files/0001.png
added some stuff
guys, if anyone can help I can put the blend project in my website
happy to share it with you
just download it and add stuff as you like
I notice some strange effect in 3D
the motor on the cnc is aligned to the gear box
in a 3D view it looks back
its an optical effect I think
looking from the top is it aligned
same for the server farm
server farm is nice now
a bit better
but not enough yet ..
the blend file is on the way
kerry_ is now known as rayh
hi rayh !
giacus: how long did it take you to do anything in blender without fussing about for hours?
[13:22:09] <giacus> http://www.giacus.org/files/emc.blend
you need Blender 2.41
giacus: i want to know if i should learn blender or not
please let me know if you add funny stuff :D
giacus: brlcad is pissing me off
and blender is pissing me off too, but it seems like it has a lower learning curve
fenn: try it, it's the only way to know if you like or not
it seems can do nice things
interface is not standard
that's for sure
a bit of pratice is required
try it, you can download the binary
yes i have it
havent put the energy into it yet
that's why i wanted an estimate of how many hours it took you to learn it
because of the stupid interface
why do people make stupid interfaces?
interface is very powerful as well
yeah yeah, i think it sucks
intensive use of keyboard
yeah check out brlcad!
90% command line
I halso had some issue with it
since i'm using ion and lot of keys combitantion are already used by it ..
ALT, CTRL, etc ..
dammit windows should be managed by the window manager
but people with stupid ideas about interfaces shove them down your throat
fenn: reading at the blender wiki, some day is enough to learn the base concepts of 3D modelling
giacus: part of the problem is i am already too familiar with 3d modeling with "standard" interfaces
but i no longer have any of that software (and if i did it would be useless anyway)
I like the armature stuff and lattice
you can animate a model as you want
i dont want to animate a model
i want to make cad models and simulate them
but blender is designed for making cartoon penguins dance
fenn: try catia ;)
that's why so far i've stayed away from it
alex_joni: send it right over :)
its only what, $12k?
i dont want to use catia
i want a good, standard, common, easy to use, GPL'd client that is intended for CAD/CAM use
let me know when there is one ;)
i'll let you know when it approaches the usability threshold
there are a lot of half-baked projects out there
"good, standard, common, easy to use, GPL'd"
i can define each of those if you want
nope, I agree with you
but let me know when there is one that fits all those ;)
as I haven't seen any..
well, standard is sorta a combination of easy to use and common
also using standard interfaces
and good doesn't mean muchh
there arent any standard interfaces though
unless you mean user interfaces
g-code output, dxf/stl in
also tons of others
ok, but that is only a small subset of the data
did you look at that article link i posted?
should be working on a presentation now :(
basically they want the cad model, tolerance, and functional specifications all in the same file to be bid on in a reverse-ebay process
or possibly to use with automatic quote generating software
buyer puts up a specification, contractors bid on it
compressed file is here: http://www.giacus.org/files/emc_blend.tar.gz
I forgot to gzip it before ..
4 mb dsl ! :D
an0n is now known as anonimasu
I have a ballscrew mounted now :)
i've got lots of pics
I'll post them at www.io23.net later today
when I boot the work laptop :)
io23 seems down
remembered it my connect is down
i'll fix a backup in a bit
turning threads were surprisingly simple
the only hard thing is that I lack a dro :)
but dial gauges work :)
digital read out
big numbers showing position
so anonimasu turned the threads in a manual lathe?
Lerneaen_Hydra: needed to have a ballnut mount that were extremely straight
straight/in line with the rest of the stuff
and on my other machine I welded a nut there with the correct threads..
since I have brand new ballscrews I didnt feel like doing the same..
thoose were new too but I didnt have stuff to turn threads :)
Lerneaen_Hydra: how's stuff going with your lathe?
Im converting mine as soon as I have the mill running
if you started welding on that precision swiss machine i'd reach through this console and do bad things to you
oh I didnt weld the other one either
just on the mounting plate
I am pondering if I should start a robot thread at cnczone
but it might be better not to
you will get a lot of "me too" but nothing of substance, that's my prediction
* fenn is anti-cnczone have you noticed? :)
oh so am I..
but I feel like throwing my palns around a bit
err plans that is
anonimasu: It's actually progressing quite well
currently I'm adding jogwheels, external estop, and a spindle on/off button and relay
after that I should only have the spindle encoder left
and that's just a matter of getting some mounting brackets that can hold my..uh..what are they called, opto readers? (same device as in a ball computer mouse)
my my mill is inertia matched..
the inerta at the motor shaft ends up the same with the higher tpi screws les had as a suggestion and the gearings
as my screws I have now and direct drive
0,00065 vs 0,00064 or something like that
and I can ignore the inertia of the reduction :)
sounds like a good deal
no meeting today?
i think the regular sunday meetings have been out of fashion for the last year or so
but what do i know
i cant really tell the difference between a regular meeting and normal irc blather anyway
I'm wondering does anyone have any docs that touch on finetuning of traj / system planner, and overall timing?
graphs / examples anything is good...
ottos: it would be best to start by searching through the mailing list archives
there have been some discussions of the above
ottos: the default cycle_time is way too high
i dont know why it's so hihg
fenn: it has been reduced
at least in HEAD
probably the old lookahead planner needed a lot more time to calculate stuff
whereas now we've sorta pushed a lot of that stuff into userspace
ok.. will do some digging..
ottos: posting a message to the dev list, seldom remains unanswered
sorry to ask all the time querstions about the traj planner, lookahead, but it's the only thing that bothers me on my mahcine is jerky movements..
did anyone make some tests on max block processing speed on a given machine clock..?
ok back to the lab.. thankx..
who's got ops? someone change the topic to 2.0.1
doh he left
well anyway if he looks at the dev list i just posted what i woulda said anyway :P
alex_joni has changed the topic to: Welcome to the Enhanced Machine Control forum - a linux based CNC control. | EMC2.0.1 is out .. | Home: www.linuxcnc.org | wiki up @ wiki.linuxcnc.org | EMC usage map: www.frappr.com/emc2/
thanks for pointing it out ;)
some programmers are too smart for their own good
i am cinfiguring emc and when i move one axis manualy, i get "jount 0 following error"...what thoes this mean?
is there feedback?
fogl: this means the motion controller didn't expect the axis to move
or it didn't move as it should have
alex_joni, he moved it manually.
what feedback...these are steppers motors
so no encoders... odd then.
fogl: what do you mean "when i move one axis manualy"
by hand, like turning a wheel, or with the jogging feature?
with emc, but not running the g code
fogl, the more details you give us the better.
a selected a manual contorl (axis interface) and clicked on + button
and AJ, take it away!
AJ = alex_joni
fogl, can you post your .ini on emc.pastebin.com?
with steppers a following error means you have a misconfiguration, we just have to figure out what it is
fogl... version of EMC would be good too. :)
Anyone notice that rapping your fingers against a hard surface, causes your fingernails to grow faster?
yes, I assumed you are using 2.0.1, but it's best to ask
hmm... maybe it's just me.
A-L-P-H-A: could be...
warm temperatures make them grow too
pulling on them with pliers helps too
here is my .ini file http://pastebin.dyndns.org/295
STEPGEN_MAXVEL is wrong
you need to put that higher than MAXVEL
can your machine really move 100mm/sec??
10cm a sec. wow. that's fast.
and you have 33000 steps per mm??
that's a step rate of 3MHz which is totally unobtainable with software step generation
I should take a look at jepler's ini generator, and use improve it.
what is this STEPGEN_MAXVEL...i dont find the explonation in user handbook?
[17:37:27] <A-L-P-H-A> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?SandBox
search then in that page, stepgen_maxvel
fogl, what version are you using?
testing 2006 04 09
cradek: when using a parport pin as an input, what type of circuitry do you need? floating for 1 and pull down for 0? or something else?
I use pullup to +5v, and the switch to ground
cradek: is there computer +5V that's easy to take from something?
that's the problem - for me it's always been available from outside the computer somewhere
cradek: oh, ok. I'm doing this in a control box, and I want ground to be common for both. maybe USB is viable, I need +5 for my jogwheels too, so that may be a good choice
can one just take a usb cable and jack into the outermost contacts to get +5 and ground?
yeah it seems like usb could work, or just run a power connector out the back of the machine
and if so, then ground for USB and for parport should be common?
yes I think so (to both)
but I've never done it that way
I'll test with my voltmeter
I have completely removable cables everywhere so I think usb would be quite good to have there
Any idea of how much current you can take? IIRC you got a low base current, and if the device requests more it can get more
I think there are low current and high current USB devices, but I don't know anything more than that
still, a few mA should be safe. the pullup for ttl is 3.3kohm at 5V which would give 1.5mA, and my encoders take 10mA each, so a total of under 50mA.
right, I'm sure that's fine
the new jogwheel stuff works very well, I set mine up yesterday
and it works well with axis now
ooh, sounds nice
I'll have to cvs&compile when I finish my jogwheels
cradek: did you write a book ?
[17:56:26] <giacus> http://www.giacus.org/files/0001.png
[17:56:51] <giacus> http://www.giacus.org/files/axis_front.png
wonder if I'm violating any (c)
giacus: it's spelled AXIS not Axis ;)
usb can supply 500mA
fenn: from one port
brasil won again
Hi all... is anything installable on the live ubuntu CD... my laptop sounds like its in an oops loop
FRED was on for under 3mins... SCORED.. ; )
I'll be back in 5 minutes
i just watched the match
austrailia played well... brazil played well better...
with a bit of luck ..
6 points in 2 match's
i still like Croatia...
yeah, Spain and Argentina too
croatia... played some of the CLEANEAST football last wee i have EVER seen
dmessier: have any parallel port on the laptop ?
ohhh my laptop just woke up... been 30 minutes to install some guitar tab sware
old laptop ?
1.8 or so
not if it wont come home... ; (
ohh... icons.. ; )
me son just got their butts fed to them 6-4.. and still got a trophy..
dmessier: what software
guitar pro is great btw
i cant even see the options any more....
my son loved utumbu when he could log onto MSN
then he spotted add programs...and so the sagga goes
found somethin' that let him d/load guitar tabs and edit them... and play them... so i expect its grabbing all the dependencies.. ; )
but how long could it take??
"EMC1 and the variant with BDI is more stable and thus there
are more options to getting it up and running."
aiee.. some people will never get it
who says that?
some guy (David Frantz) on the dev list
did he try emc2?
Subject: *****SPAM***** Re: [Emc-users] (no subject)
alex_joni: that sure was a strange post on the mailing list (I got it on the users list too)
chinamill: god afton
its callled songwrite... i just got a whole lot back...
dmessier: A-L-P-H-A has been looking for you for a couple days.
thx... Jymmm... have him call me..
my calls in... tag hes it.. ; )
anyone here ?
do you know a lot about servo systems ?
heh, next to nothing
sorry, you'd better wait for someone who knows more about them. IIRC jmkasunich knows about them
I'm more stepper orientated (ATM)
you'd better just ask and see what answer you get
what kind of "lock" range, in encoder counts, should I expect ?
what do you mean "lock" range?
i.e. I twist the shaft by hand, and before the PID loop starts correcting there is a bit of "play"
that's mostly the deadband setting
oh, deadband should be about 1 or 2 encoder counts
now I get about +/- 80 encoder counts
also, too low an I in your tuning will make it sluggish to respond
Lerneaen_Hydra: what strange mail?
+/- 80 encoder counts is probably too much ??
alex_joni: the one you were talking about
I need to sand some acrylic with 200grit. Do you think if I used a 3500 RPM bench grinder and slapped the sandpaper on it, that it'll fuber the plastic?
3500rpm sounds a bit much IMO
why not a vibratory thingy?
If it's a small piece and you cool it enough maybe it would work...
anonimasu: not the vibrator, the 3500rpm
yeah, but why not one?
dont 95% of all households have one
not a grinder, a um sander
oh, yeah, that would probably work
depending on how bad it is though you could just do it by hand. (glass, water, soap and grit)
way too many surface feet todo by hand.
plus needs to be square... no round overs
aka poor mans disc sander
just not sure on the RPM's
Jymmm: it'll work with the right feed
so would walking thru the propeller of an airplane =)
you first =)
surely you have a material sample..
6500 is fast ;)
Lerneaen_Hydra: what do you mean?
alex_joni: you wrote that ""EMC1 and the variant with BDI is more stable and thus there are more options to getting it up and running." some guy (David Frantz) on the dev list", then I said that the same person had posted a similar reply on the normal, users, weblist
I might have confused what list it was
I get them both in the same place ;)
alex_joni: oh, ok
that would explain things
heh, the time from when I first said something to when I explained it was rather large, 2 hours. ;)
yeah, I watched a movie in the mean time
alex_joni: Power Puff Girls
hello, can someone tell me, what are these errors i am getting every time i move one axis: http://pastebin.dyndns/296
Jymmm: now quite
fogl: yes, your machine is not configured properly
and emc can't keep up with what you are requesting
fogl: you have max speed of 100mm/sec
and 30000 pulses / mm
... that's a bit too much
not any more
fogl: can you post the ini?
g'night everyone.... *yawn*
[20:48:55] <fogl> http://pastebin.dyndns.org/296
[20:49:00] <fogl> http://pastebin.dyndns.org/297
ok, it seems you started with an inch ini and adapted ;)
but there are some things there that don't quite make sense for mm
FERROR = 0.050
MIN_FERROR = 0.010
0.01 mm is tiny
and at 40 pulses / mm you only can do 0.025
I would recommend 0.1 and 0.5 or so
* alex_joni wonders if he's talking alone
fogl: increase FERROR and MIN_FERROR
sorry...i was disconected, any adia wat is wrong with this http://pastebin.dyndns.org/296
(this are the errors i get) http://pastebin.dyndns.org/297
(my ini file)
fogl: increase FERROR and MIN_FERROR
by a factor of 10
this is better now...now i get this error onl when i move one axis manualy in continuous mode...and when i relese the + button
increase it a bit more
is there a way to change the ini file while emc is running, or should i restart emc every time i change ini file?
kerry_ is now known as rayh
BUT WHY ARE WE YELLING?
why do I always read the news? I hate the news
can't stop yourself eh?
hmm, don't cut up a bunch of garlic and then pick your nose
they should teach that in cooking school
so whacha making? if it has garlic in it it must be good
done and eaten already
I got potatoes, turnips, radishes, onions at the farmers market (no old-people jokes please)
also rosemary and dill
well, had that
lots of it
made a biscuit "crust" and put it on top of the whole works and baked it
it was really very good.
yeah, kind of
sounds like it
too hot here to be baking anything
I never buy stuff like turnips at the store, but when I see locally-grown ones at the market they look good
although I would make an exception if "anything" was "brownies" ;-)
that's what central air is for! also I have a new-ish oven that doesn't seem to heat the house at all
we have central air, but the oven just makes it work harder
yeah brownies would be nice. I never seem to make desserts (probably a good thing too)
I'm in the basement where its nice and cool (almost chilly)
but I was outside for several hours earlier
yeah basement workshops are very nice in the summer.
and in the winter I just put a space heater right nearby
ours isn't bad in the winder
it'd be better here if I'd fix the seals on the doors etc.
I installed a furnace register in the main hot air duct, in the winter I open it
pumps heat into the basement, then it rises to heat the rest of the house
in the summer I close it, then duct tape over it to seal it good
I hate home maintenance, but I sure like having one
beats the heck out of an apartment
apartments are fine for eating and sleeping, but not so good for a lot of hobbies
definitely not good for hobbies that make chips
machining isn't really that noisy
now if your other hobby is playing drums....
before I replaced the spindle motor on my little mill, I wore earplugs full-time when using it
it was terrible
oh, high speed stuff
I guess, if you call that high speed
but yeah, good machinery, like my "large" lathe, isn't very loud
hmm, I should ask LH to add a threading canned cycle on that wiki page he wrote
I bet I could whip that together if he'd figure out how it should work
I gotta figure out what to work on
got a lot of machining to do, so I don't want to get into major emc stuff
there's several things I want to do, but I'm too scattered to start on them
focus on little things instead
you're making more parts like the ones you did before?
got an order for 2 CIM jigs
probably 100-120 hours of work
