CNC threading is so cool
* skunkworks thinks jmkasunich still likes his cnc
yes, yes it is
jmkasunich: part of the e-week project again?
did you make a fusee(sp)
no, just a thread
the fusee will come later
what is that?
fusee? a tapered drum that a rope, chain, etc winds up on, or unwinds from
used in spring clocks so that even tho the spring gets weaker as it unwinds, the force on the clock movement remains constant

#emc - the educational channel!
(I didn't know what they were called until a couple weeks ago)
well, what do you expect from me, I was asking what the scroll was called on a scroll chuck yesterday
BigJohnT: gezar: do you know about the conversational tools already in emc? I used them to do several Heidenhain 'macros' http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Cp1
the output generated Heidenhain code for me, its very flexible
jmkasunich: nice plaq
a 'mop' is a text file describing the inputs, field names, and any math, then the output format. mops are added to the menu

I hate getting the corners correct.
I guess I hate plastering in general
I like plastering, but I'm not as good at it as I think I am
heh - I am not good at it for sure.
my house was all skim coated
so when I do something, I feel compelled to skim coat
that is how dad does it..
sure flattens things out nice
last time I was at lowes, they didn't have plaster
Well - I say plaster - but I use durabond 90
that's a drywall compound?
yes - 90min open time.
mix with water and go
doesn't shrink much at all
compared to the stuff in the pail
(never used it)
I'm too lazy for that, I use premixed
plus it is pretty well dried in a few hours - makes things go faster.
cool... I just generated a 380,000 line gcode file and axis loaded and displayed it with no issues !
thats quite a program
takes about 30 seconds to load... seems to run, but it doesnt appreciate it when I resize the window
what kind of part does it make
its a great circle map of the world... converted from a pdf file
I wrote a gcode module for pstoedit
[02:05:43] <LawrenceG> http://imagebin.ca/view/gejkSG.html
need a tiny cutter to mill that
thinking of a pcb v cutter and engrave it on the back of a piece of plexy
LawrenceG: what dimensions?
I need to figure out how to get rid of some of the detail..... also, the current code has no arcs or curves support
the pix is about an 8" diameter circle... scaleable in the gcode
LawrenceG: is that a sphere?
a great circle map centered on my location
thinking of a beam heading indicator
200k line gcode?
300k line gcode?
that must means it's mostly broken points
mostly closed polygons
LawrenceG: what did you use to generate the orginal drawing?
a 14mb file ... see http://www.wm7d.net/azproj.shtml
I feed the pdf file through pstoedit (which I wrote a gcode output module for)
wonder if pastebin will take a file that big?
They have LJ (HPGL) output too
HEY! They have PS output
Though, I'm not sure how to get it
LawrenceG: The AZ project is actually written in PostScript =)
yea.. it is a little wild... never done anything ps ps before
oh PS is very very cool
It's a complete programming language in itself
yadda yadda yadda
I'd LOVE to have PS replace SGML
stacks we use can all then
fenn: how much have you had to drink?
PS doesnt do animation or user interaction (or have any libraries worth speaking of)
not to mention it warps your brain
fenn: True, but if as much effort that has gone into SGML put put into PS, it sure would be
fenn: PS, not EPS
i didnt say eps
fenn: Ok, np. Some ppl think they are one in the same.

just won a Z axis for my pcb mill
looks like a nice piece of gear
lil surface rust, but no biggy.... nice LawrenceG!!!
I suspect shipping will be high... he lists $45 and said he would ship USPS for additional $15
looks fairly heavy
acme screw? looks very fine pitch
looks like a micrometer screw
LawrenceG: If you haven't paid and it's smaller than 8.5 x 11" UPPS Flat Flat boxes are $9 for up to 75LBS
Jymmmm: the auction has pics with dimensions, its 13.5" plus a motor long
yes... it does look very fine. Thanks Jymmmm ... I think its too big and there is a 20lb limit on international I think
probably close to 18", theres a stub shaft on the back of the motor
international? isn't it in NY?
LawrenceG: are you in the US>
Well, just trying to save someone a couple bucks....
oh, BC, right>?
even replacing the screw is an option... jmk I live in the great white north
jmkasunich: LawrenceG is a canook
LawrenceG: do you have a spindle picked out?
BTW... I broke down and bought a safety relay
if its gonna be a Z axis, that screw might well be fine
there is enough metal there that the weight might serve as preload - PCB cutting forces aren't that high
and Z speed isn't critical for PCBs either - they tend to be rather flat ;-)
Heh, gawd I hope so =)
Man, that is a fine thread aint it
jmkasunich: for the spindle, I am going to try a porter cable trim router... about 30k top speed
It looks like it probably a stepper on the drive end
thanks Jymmmm ... I dont see anything that looks like that table.... probably a few years old
LawrenceG: Once you get it, call Parker they're really nice about finding docs and such.
sim is now at line 125000 and still running

yesterday, scifi channel had all day marathon of movies about people stopping tectonic plate movement with nukes, 4 unique ones I think
hmm.. nuke out a large crater and fill it with water?
I didn't really watch any of them, I was moving my mill back and forth
8" at a time
I think the idea was to destroy L.A. and cause an earthquake in all of them except one though
in another movie on scifi, I found out that if you try to drive your car in 130 degree heat, it will explode
don't tell the people in Az that, the gridlock will be horrible
maybe they meant celsius
doubt it, they were in L.A.
maybe it was a pinto
the first car to blow up was a Taurus, so the same management team was involved
second vehicle to go was a Chevy Suburb
I got a cheapie digital caliper from harbor freight - they were on special
it seems better than you would expect for the price
they're not bad until they go bonkers
$14 I think

I don't have gage blocks, but on my B&S 123 block it shows 1.0005, 2.0005, 3.001
is that after you zeroed it I assume?
I think the 123 blocks are supposed to be ~ 0.0002 oversize
why would they do that?
so you can lap them to size if you care enough
sounds like a good time
yeah no kidding
I can see lapping something flat, but maintaining flatness with the other side would be difficult
I think you could do pretty well for .0002
you weight the thing being lapped
one side laps faster
and once you get the geometry, it stays that way when you flip it over
it makes a sphere - any telescope maker knows that
I think I'll leave them alone!
or you can grind them
you can lap them, but its not done block to block
that's what we do, we have big (6-12 blocks) sets that we grind together
grinding .0002 is a pita
not for us though
but toasty is special
our grinding work is all +/-.0001 over big distances
and if you get your matched set, it doesn't necessairly matter that they're undersize
they're all the same size, so who cares?
hey, any of you set up the vsftpd?
I cant get something with it working right
ftpd thats available to the emc version thats on ubunto
v stand for very?
its one of the better ftpd
but it's sftp?
I believe it has a ssh component, im not sure
ssh has built in file transfer protocals, that smoke ftpd use anyway
yeah, I only use sftp, which is ssh version of ftp
especially if your using keys
I just want a simple ftp to work, so I can move stuff from this win box to the lin box
I'm pretty sure I've used sftp on ubutu
thats a missnomer, im on the win box, using ssh to use the lin box
eric_U: arent you thinking 'scp'?
sftp is really nice, but if im going to use ssh, ide perfer scp
maybe I just need a better wiindows method then ftp..
i use sftp on cygwin
cause as it stands fire ftp and the linux box do not like to play
iirc, putty has an scp client called pscp
yes I think so
is this two machines on the same local network?
I use the openssh client on windows too
then it looks just like a windows machine
99% of my linux work is done via a putty terminal
wanna test to see if my http tunnel works? I asked last night but nobody was on to try it?
its just a forwarded port from my router to the linux box for http, I dont know if it works outside the network because of names
what's your router ip?
www.masternode.net should work
it should return an open dir structure for apache
sweet then, thank you
Seeing this instead of the website you expected?
ok, so I changed directories
no, its normal, I just wanted to see if traffic outside of my lan, wan baised could reach this boxx
ha, ford is recalling tauruses because they might catch fire
yeah, its still not working from the linux box, sigh
sweet, its working now
I belive as anon at the moment too :)
sweet, now its working in full user mode
I had to load a kernel module
oh this makes me happy
cradek: you still around?
not for long
does axis have the ability to graph specific functions?
I don't understand the question
neither did I
im trying here
in John's counter bore app, could he have an axis portion, that as the user inputs data, about the counter bore
could axis be made to essentially, draw that tool path in his app's window?
no, but he could make an active preview separate from AXIS, like holecircle does
holecircle updates a preview of the holes as you change the various fields, and when you're happy you hit OK, and the gcode is generated and fed to AXIS
im learning c this year, so Im hopping I can start helping with emc for once
the more the merrier
john's stuff is all in python - maybe a better first language to learn
depends what exactly you want to do in emc
hardware drivers: C. user interface stuff: often python
yeah I know
noo cnc cuts metal :))
cutting a ratchet to test it then a production one in a few minutes
I havnt finished building it yet !
not till Im back on windaz later
then will have pics and short gear cutting .mov

anyone want to be a second pair of eyes and see whether the Axis Configuration's Pulley ratio fields behave like you expect?
and I somehow got it magically working in the end
jepler: did you read jmk's and cradek's discussion about it?
alex_joni: no, when was this?
it seems it either works right or backward if you think about pulley teeth or pulley turns
I miss too much on IRC lately
jepler: recently, not sure what channel though
jepler: in devel /lastlog teeth
I agree, it should be clarified
jepler: cool :)
it was on devel
'Pulley teeth (motor:leadscrew)' would seem like a good way to clarify
too bad it'll break any translations
we'll fix those
this will only be for 2.2.4, so translations could be ready by then
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-02-04.txt
In RS274/NGC how can I reference an axis assigned as a variable? For example I am trying to create a routine that will make the necessary number of passes like this
#1=X (Cutting axis. Enter X, Y, or Z)
#1 0 (Move the selected axis to 0)
you can't, variables can only hold numbers
ok -guess I'll have to think more on this
just the question is the gcode interpreter in emc "open" ?
I don't understand the question
what do you mean "open"
free to changes
the source for all of emc2 is available under a free/open license, the GPL2
i love to change stuff in heidenhain control and play around with it...
jepler: you can have a variable for each axis
jensor: you can have a variable for each axis
and for the ones you don't want to move, you just don't change the value
when I tried to run
#1=X (Cutting axis. Enter X, Y, or Z)
#1 0 (Move the selected axis to 0)
I got an error
uh, weren't you here a minute ago when I answered your question?
jensor: not like that
jensor: g1 x#1 y#2 z#3
and #2 and #3 are 0
so only x will move
no, y and z will move to 0
I think he wants to not specify y or z move
then switch to relative G91?
maybe you want to use g91 mode
I want to the program to select the axis from the inpuit data
jensor: if you have the input data, you simply update one of the 3 variables above
you can use an "O- if" construct to only execute a line with the appropriate words
thats probably the wasy I'd have ot go
how would one use the o word to output a line?
this untested code (joined onto a single line with "/" marks) would move X if the flag is nonzero, or move Y if the flag is zero: O100 ([flag] [value]) / O101 if [#1] / X#2 / O101 else / Y#2 / O101 endif / O100 endsub
if you have to support more combinations, then you will have more if/else/endif blocks
I see - but i was hoping for 3 axis selection
I wanted to create a routine that would make the required number of passes to remove a given amt of material on a given axis
(Fly cut Routine for single axis cutting x)
#1=-.025 (Z down cut increment)
#2=14 (no. of increments to get to total depth)
#3=2.5 (movement along X axis)
#4=0 (Loop counter)
F5 G0 G90 Z0 X0
G91 (Incremental mode)
O1 while [#4 lt #2]
G1 Z [2*#1]
jepler: can u use the # of teeth as a ratio? like 10:20
random question; is emc-sim distro-dependant? or could it easily be installed on any version of ubuntu/fedora/<insert distro here>?
my pants are on fire
i'm looking at it that why the ?
that is how I read it. it is asking for pully teeth
you can still put in the ratio if you want.
yep - 16:32 is the same as 1:2
k but no mention of ratio
if someone doesn't understand that the ratio is based on the number of teeth, then they are probably not qualified to set up a CNC
cool but I guess I didn't understand the problem people had before
I think it was that there's soem ambiguity when you ask for a ratio - is it motor:screw or screw:motor
and even then, is it teeth or turns (reciprocals of each other)
asking for the number of teeth on each pulley should be unambiguous, even if it isn't the question peoiple are expecting
hope it clears things up
yeah, one would hope :)
simple mechanic ;)
Hmm I myself would find motor/driveshaft-ratio to be the least ambiguous, but oh well
so 2:1 would be a 2x reduction (two turns of the motor -> 1 turn of shaft)
* archivist wants shooting if he cant understand a ration/gear a gear b
as not all systems actually have teeth/cogs
then again, I'm just a bit pendantic atm

lerneaen_hydra: it was
what about RT stuff?
getting RT was just a matter of compiling the right kernel patches
I've heard that it was very difficult, maybe just people that don't know how to apply kernel options (myself included)
ive tryed to patch a rt kernel for gutsy gibbon and failed ;)
though I can't say I've tried ;)
not yet at least
it would be nice to have a vanilla .deb with emc simulator
with no special dependancies
ive tryed with an vanilla
for 7,10 64bit
somehow i get an hal error and no one can help
when my cnc is rdy i going to set up an additional pc for cnc purpose only
64-bit systems work (http://axis.unpy.net/01180573281).
I also experimented with 7.10 and found that it worked with one tweak, the modification to /etc/security/limits.conf shown here: http://cvs.linuxcnc.org/cvs/emc2/debian/emc2.postinst.diff?r1=1.3;r2=1.4;f=h
I haven't yet tried 7.10 + 64-bit.
nice i will take a look
jepler; is that with RT or just sim?
unfortunately I don't have either of those systems handy, so it's possible some incompatabilty has crept in in the meantime
lerneaen_hydra: with RT
oh, sweet :)
I presume you'll jump to 7.0X when it's released?
We hope to make official packages to go with Ubuntu 8.04, the next LTS release.
err, I meant "I presume you'll migrate to 7.0X (next LTS and all) when it's released", and to the EMC devs
err, right, 8.0X
8.04 is coming in april right?
otherwise it wouldn't be called 8.04 ;)
you got me ;)
Right, the release is named for the year and month, so 8.04 is the version released in April 2008.
ah okay im relative new to linux so please excuse me ;)

schema and layout, its audio io for an atmel arm7 header breakout devkit
so like, filter-input preamp, and 4pole active filters for the pwm channels
try and do some 44.1KHz at 10b resolution type stuff
dac or pwm for output?
isn't pwm used for controlling servos?
its got a clock divider/pll multipler on the main oscillator
pwm is used in lots of applications where "analog" control is desirable
e.g., stuff as simple as controlling the brightness of a LED
so i can prob set the fast timer to a few cycles, get the output freq pretty close, try to keep the prob speed bit above 50MHz
jepler: yeah, but how would you use it to produce sounds?
i done more dac stuff
i put AC and DC coupled outputs so it should be pretty versatile for control stuff, besides audio processing and synth
maddash: pwm -> RC filter produces an analog voltage. Give that as the input to an op-amp that can drive your speakers/headphones/whatever.
dunno how great those amps are close to the rails, tho
yeah, you get an voltage average as a function of the pwm duty
you just have to filter below the pwm switching frequency (im prob gonna do 10KHz or 20KHz filter rolloff freq)
because high end in audio is trash
page 1 gives a bare minimum intro to pwm in the context of audio, and page 2 shows a simple scheme (R+C+op-amp): http://ww1.microchip.com/downloads/en/AppNotes/00538c.pdf
-- renesis's circuit is much more sophisticated than that.
i just dont get it why do you want to make audio out of an pwn signal? pardon me im german and i may just understand something not proper?
45.1584MHz pwm timer, for 10b resolution
because it wont look like pwm after you filter it
people are used to 44.1KHz DAC audio as analog, usually but not always filtered
your ears will filter it if they dont in the cd/mp3 player output circuit
fretless85: class-D audio amplifiers are just pwm + feedback
thats how they are so effecient, they fets are either full on, or full off, except for a short period during transision
both states burn 0 power in the output circuit
I wonder why no micros seem to have pulse-density modulation modes.
to me an audio amp should look like that (half way finished) http://mitglied.lycos.de/fretless85/R0011305.jpg
like, triangle instead of saw based
jepler: so the pulse centers are evenly spaced despite duty cycle, yes?
fretless85: you're a a traditionalist
(because avr timers mostly have that mode)
renesis: no, that's not what I mean. http://en.wikipedia.org/wiki/Pulse-density_modulation
I think many micros have the mode you're talking about
tubes also have horrible consistency
even new shit from russia and china
(heh i did QA for little audio tube warehouse for like 6 months)
like, you could do all that, analog, no switching, without the glass and without 40lbs of copper
i brought a bridged dual chipamp into work, like 100W on a 2x4" board, and they kinda handled it like it was going to bite them
but yeah, tubes are neat
class A 20W per chan
prob burn 100W in the amp =)
i think ideal theyre like 25% efficient =\
probably even worse :P
but i dont care
yeah rarely things are ideal
[21:28:38] <fretless85> http://mitglied.lycos.de/fretless85/R0011241.jpg
AB max effiency is something like 85% ideally, most amps do like maybe 50%
some got to stick with the traditions ;)
hey and fuck the efficients we germans pay enough on "Öko" taxes :P
85% on our fuel are taxes believe it or not
the fuel costs here about 1.4€ thats about $2.1 a liter
fretless85: you like nixie display tubes?
you have to convert it to gallons or we won't 'merkins won't understand it :-P
1l=0.26 gallons btw
so about $8 a gallon
we thought the gas prices on ireland where pretty good until we figured out they where in liters ;)
looks like in my state the total tax on automobile fuel is presently about 13%, but the taxes are written as an amount per volume (e.g., cents per gallon) not a percentage.
we got 19% more added value tax (caution the translation of "Mehrwertsteuer" may suck)
I think the usual translation is "VAT" for "value-added tax".
thanks for the correction
my english is far away from been perfect...
you're doing fine
for a german :P
at least we got nice beer ;)
If I may ask, what part of germany are you from? I've got a friend in Frankfurt, and family in Berlin and Dresden.
im native from (is native the right word?) a village near dresden, now i leave near the "ruhrpot" a city near duisburg
not leave pardon me
so i got to drink "diebels" ;)

oh let's see -- most of the time I'm in germany, I spend in the three cities I mentioned already. Munich, Koln, and Trier are the next three places that come to mind. I've also probably stopped at each station the ICE train goes to between berlin and frankfurt, I've made that trip so many times
Haven't heard from them in a while, so I guess it's still working...
trier isnt germany? or may i mistaken something? ;)

its the second smallest smd
“0603” 1,6mm x 0,8mm
0.06inch x 0.03inch
arnt you afraid to breath this stuff in?!
fretless85: turret boards?
[22:03:51] <jepler> http://en.wikipedia.org/wiki/Turret_board
maddash: for what?

you can do soic and 0805 by hand with a good regulated soldering iron
soldering wire size doesnt matter
because you wont be using it
not me renesis *g*
(I don't quite understand that description, though)
other than to tin your tip
renesis: good point
QFP and SSOP are doable by hand, but you gotta be good
i havent tried yet, but i think i can do it
fretless85: if that's your photo you should add it to the wikipedia article, after reading it and then looking at the photo again I think I understand what "turret board" means
thats my photo
it is odd to me to call the stand-offs 'turrets'
belongs to that amp http://mitglied.lycos.de/fretless85/R0011305.jpg
skunkworks_: if you want to see some smt soldering methods, look up maybe 4 or 10 smt soldering vids on the youtube

that amp got the same boards
theres a few diff methods, but theres a vertical soldering method that works awesome
you basically use gravity to keep the solder on the iron
and then the metal and flux will wick up the exact amount of solder they need
can use same method to fix bridged gaps
just kinda drag the iron across the row of pins
it looks easy but im sure timing and temps gotta be pretty dead on
and its damn small...
but yeah, for soic and 0804 you dont need special tools, just an iron wont burn the parts, flux, and tweezers
0603 is a bit harder (i dont use magnification), but its doable with a tiny bit of faith
I shake too much.
if you can do qfp and ssop you are basically er337 solder tech
naw most methods it dont matter
its prob even help, actually
I like bigger componants. http://www.electronicsam.com/images/KandT/servostart/top.JPG
if you have trouble keeping parts steady, you can glue the parts before soldering
is how they do smt wave soldering
i even cant weld properly
either glue or sticky paste
because of shaking hands

has any of you encountered TTL expired in transit. while pinging a host?
fretless85: 7 segment vfd display tubes
(also pretty efficient smps supply setup)
im making a clock
hehe, got backlogged for a bit, but all i have to do before machining boar is the buzzer circuit
piezo thing, shouldnt be hard
yea i thought about doing a nixi clock
mine will have wwvb time sync
maybe my next project after finishing the amp and my cnc mill
depends how ninja this little reciever with serial out is
it like a $2 antenna and an $8 chip
chip has 2bits for signal integrity indicator
but if it gets to tiny i will fail... ;)
its like 60mm ferrite coil
alex_joni, i got you
i havent messed with radio stuff since school
renesis, thats the right size for me http://mitglied.lycos.de/fretless85/shw.jpg
hehe, i put my scope on the antenna (it has integrated cap) and got the cleanest 60KHz sine, omg gorgeous carrier wave
i didnt think it would for i dunno why
nice machine center
if you can stand on it without braking it--->right size for me :P
okay i needs foods
nice talking, bbl
but my hands shake to bad for that smd "shit"
see ya renesis
tomorrow i got some nice hooks to machine ;)
2 pieces 13000pounds each
they can carry 660000pounds each ;)
maybe i post some pictures within these days
im gonne get some sleep...got to get up early (6:00AM)
see you guys!
good night all
can i use my cnc for multi-layer pcbs?
drilling or machining pads and traces??
sure, why not?
but the holes will pass thru all layers and you can only mill the top and bottom of the board
so...don't drill so deep?
hm, let me go check
properly designed multi-layer it shouldn't need to be that extreme
