heh somebody at mesa has a sense of humor
from their manual for the 7i40 "This page intentionally almost blank"
most of their manuals have that
I like it too :)
SWPadnos: how goes it?
pregnant with tripplets?
not that I know of
pregnancy isn't one of them
1) the washing machine died this weekend (with a load in it, of course)
CL alwasy has W&D, many free even
2) I needed some parts from DigiKey today, but missed the ordering cutoff on Friday. Then their credit card processing system was down this evening, so I couldn't order today either
(so now I'm 2 days late getting this stuff, which will hold up other things)
and 3) I'm so far behind on another project that I can't even estimate how much extra time I need
said estimate being due tomorrow morning
so as I say, so-so
oh, and my wife is planning a nice trip, which she has to take without me because I have so much work to do
Hmmm, go hug your SS enclosure, it'll make yu feel better.
yes. it's probably cooler in the garage
SWPadnos: Oh did you see the fan I posted?
[02:19:27] <Jymmm> http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100662921#reviews
$40 of awesomeness, and much quieter than the old pattons
Even on LOW it moves some ar
On HIGH, just attach wings and a couple RC servos
and a REALLLLLLLLLLLLLLLLLLLLLLLY long ext cord
I went back and bught another one actually.
SWPadnos: you could care less right abut now, huh?
more or less ;)
SWPadnos: Hey it's all good... you just mentioned "cooler in the garage" which implied hot in the house, so I thought that might help out in that dept.
it's not hot, about 76 in my office
it's just balmy here
I think it didn't rain today
or yesterday (much), come to think of it
Didn't rain here either, just balmy thae last two das
SWPadnos: well, I know it's almost your bedtime, so hasta!
SWPadnos: Go kick a (ceramic) cat or soemthing
no time for that
's a fairly cool looking fan
any idea why axis would show up with a blank window and hang the machine?
a guy on the forum is having that happen
hmm, how would I have him check for that?
run another opengl program like glxgears
Ok. I told him to make sure visual effects were turned off. I had the backplot do funny stuff on one machine when they were on
also good advice
ubuntu turns on "desktop effects" for certain Intel video chipsets even though it is broken in the way you described
.. for nearly two years, and by default, despite a huge number of duplicate bugs filed about it
not if you install with the linuxcnc cd
I would presume opengl is there because if it is not axis gives an error and exits.
their answer is "nobody uses opengl and doesn't run fullscreen, since it's for games"
there is a lot of advice recently to avoid our cd - I'm not sure why.
I don't know how he installed. I just used a standard ubuntu cd on the computer aforementioned.
yeah, that would do it, depending on your video card
don't know. I haven't tried it yet myself.
who is giving said advice?
Valen: I've seen it several times on the emc-users list
I think it might be because you can get the 8.04.1 CD which has better hardware support
IE atom stuff and other such
if you then replace the kernel with ours, I bet those benefits go away
I think so.
's entirley possible
one guy on the forum had some problem like that and had to change some hardware.
but you do at least have the option then of compiling your own kernel for it, if you only have the emc disk you cant actually install
how hard would it be to put the development packages on the CD?
I only know that for certain on atom though
mozmck: I think the cd runs pretty full, alex would know for sure
how is the cd made? can stuff like openoffice be stripped out - or is it already?
it could be
but this way lies madness IMO
the less we modify ubuntu the better
Might be an idea to have a super small livecd so people can test their hardware
then just use the packages ontop of a standard install
the best test is the full cd
heh, that's where we started some time ago
people really really wanted a full OS cd
all this talk about no internet access at the machine
that's why I wondered about the dev packages, because I've seen several people asking how to upgrade without a net connection.
you don't need dev packages to upgrade - so maybe I don't understand what you're asking
If they need to install components they will need dev
but not to upgrade to newer packaged versions
no, but if the dev is not there and they want to add it...
it requires a lot of extra packages
yeah getting the full compiler etc is a pain without a net connection
also that's a sign that it wouldn't all fit on the cd :-/
maybe we could put a list of required packages or something that would make it easier
also apt already supports something like what you want with --print-uris (you can get a list of things to go elsewhere and download)
ah, I need to read more... lots of stuff out there!
for someone new to linux it's not easy to figure it all out
easier to run some cat5 than figure out apt
also, the updates
we are tuning an axis, in manual mode it moves perfectly, in MDI or audo its all over the place..
define all over the place
I think i rember vuagley an ubuntu project to do that whole offline online thing
there was a project that would let you configure a system as you liked, and then would create either a CD or a list of installed packages, which could then be installed elsewhere easily
on the down side of the scope pattern it slows down and its as if it doesent have enough power to make it to position, and falls short
It acts like it runs from another set of PID settings when using MDI or Auto verses manual 1" steps
The acceleration and velocity are different
SWPadnos: that sounds interesting. any idea what it was called?
whats the consensus on this http://cgi.ebay.com.au/1000W-48V-20A-Switching-Power-Supply-Radio_W0QQitemZ190318518154QQcmdZViewItemQQptZAU_Security_Equipment?hash=item2c4fde1f8a&_trksid=p3286.m20.l1116
as a PSU for some CNC type lovin
4x 500W motors
sed_: running gcode in g64 (blending) mode will give you half the acceleration on some (many) moves
do you mean 1" incremental jogs?
is that long enough to make it up to cruise velocity? have you tried longer and shorter jogs?
I am not running G64. and yes incremental jogs. The deceleration is faster than accceleration in G0Y1 move
have a plot?
commanded accel and decel are the same
Longer distance MDI commands end up with a following error even though I have FERROR set to 1.000".
Not according to the scope
if you get ferror trips, the position has become that far behind
* Jymmm streaks across the channel
cradek: Seen enough yet?
I have also set the ferror to 2" and still have the problem only when moving less than 1/2"
ValenThis is what you NEED... http://cgi.ebay.com/ELECTRICAL-TRANSFORMERS-1000-KVA-13800-277-480Y-VOLT_W0QQitemZ130291505582QQcmdZViewItemQQptZBI_Circuit_Breakers_Transformers?hash=item1e55fa99ae&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A1%7C72%3A2149%7C293%3A1%7C294%3A50
yaknow mu mill isnt actually that big
just use it as the BASE =)
There should be some "its Australian for plugpack" line in there somewhere
geez at $10k it'd be almost worth it for scrap
[03:28:48] <Jymmm> http://cgi.ebay.com/35-35V-600VA-Toroid-Transformer-CNC-Controller-HiFi_W0QQitemZ370192780213QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item5631358bb5&_trksid=p3286.m20.l1116
Isn't it 35VAC * 1.414 = 49.49 VDC ?
Jymmm prolly the psu i found is dc out?
thing is theoretically I can only wind it down to 42 volts
think that would be too high for the 40v version of the 7i40?
Can i get EMC to limit rates based on total acceleration of 3 axies?
IE if my power supply isn't beefy enough to drive all motors at full power?
but it can run 2 out of 3 at full power
Or do I have to limit all the motors to 1/3rd of the available power all the time
all three x,y,z accel at the same time is a rare move
like 0,0,0 to 1,1,1
if you do 2.5d style milling you'll never have that
rare but i still don't want to smoke the power supply
We are hoping to wind up at 5 axis
sounds like the place to fix that is the power supply
that costs money though ;->
software is cheap
are you talking about steppers?
I'm mainly looking to ensure that a "worst case event" doesn't smoke the PSU
hmm I spose that can also be known as a fuse
what kind of power supply?
[04:21:59] <Valen1> http://cgi.ebay.com.au/1000W-48V-20A-Switching-Power-Supply-Radio_W0QQitemZ190318518154QQcmdZViewItemQQptZAU_Security_Equipment?hash=item2c4fde1f8a&_trksid=p3286.m20.l1116
cheap chinese style
We have some of their 12V supplies, they seem pretty good
hmm it says it has overload protection I spose
generally you can short a switcher without damaging it - it just shuts off
yeah, it is chinese though
Ah well Get one i spose and if its an issue get another
just don't put them in parallel.
it doesn't look like they are designed to do load sharing.
nah I'll put one to each controller
EMC looks interesting
I was on my way to build a cnc machine from scratch with a couple stepper motors, but didn't know how to translate a drawing into commands that my cnc machine would understandn
does EMC assume a certain setup (like commercial steppermotor controllers or using a parallel port or USB or so) or is it flexible enough ?
Xteven yes EMC is truely excellent, I started in much the same way with some steppers and driver boards then built a milling m/c
here are some ideas http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Cam
pjm__ is now known as pjm
Xteven, I also did a from scratch cnc
pjm is now known as pjm1
bah wrong button!
I suppose I should learn more about gcode
some of us hand code
I do because Im making gears
what I'm most scared of is having to implement some arc-drawing code
I cheat... rotate the A axis
there are some wizards to help with arcs
is there a list of the things a CNC machine should be able to do if I want to use it with EMC2 ?
I dont think so, its up to your imagination
often a machines construction and shape places limits not the cnc software
unless you mean the drivers for the steppers or servos
I should be more clear ;)
my cnc machine would move in X and Y direction
drawing lines is not a problem, but drawing an arc would be
and Z we hope if a mill
does EMC translate the arc in a sequence of straight lines ?
why is that
well yes, that too :)
yes gcode has arcs
does the hardware need to know how to draw an arc ?
ah ok :)
or your cam software
or cheat and have rotary axes
I'll give this a go
and hopefully start building soon
thx for the info
what do you intend making
I'm already in love with emc
I just want to make a simple cnc machine
mainly to drill holes on PCB's I guess
but probably also for all kinds of other interesting projects
some are milling the tracks as well
yeah I saw that :)
archivist: how many axis does your machine have ?
built up from scrap and a couple of new rotaries
emc must be made up of magic
EMC can handle 9 axis
this has a lot of potential :)
I was imagining I had to write all the controller software myself
luckily, I'm wronng
now I can focus on building hardware
which is my favorite part
there's a bunch of videos on youtube of CNC machines controlled by EMC2
one of them vids should be my machine!
a few picture of my mill at http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Pjm
I may admit to some
I was looking for cad software for linux earlier
do you use any ? if so, which ?
thats why I pointed you at the cam page
Im part of the group building HeeksCAD
Im testing mainly
I've tried a couple CAD programs, but a lot of them seem unfinished and missing basic functionality
I'll look at heekscad
most are unfinished
define "basic functionality"
Xteven not *nix but windows, cambam is simple and pretty good
well, not crashing for example
I've played with qcad before, its very good
but only 2D
yes the current cambam is pretty nice, it supports proper 3d profiling too
not had cause to use that as yet
what do you think about using "voice" to control movement, motor ...just like HDD voice-coil to control its head
as long as servo controlled and has enough force and damping for the job
enough force, thats a good thing to consider...
what application do you have in mind
maybe mini-CNC for building mini robotic parts
its a medical stuff
no one on earth go healty for forever
so, cheap tools must be easy to build and exist anywhere
voice coil has a limit to the force it can resist from the machine
... and other problem is the drill stuff
handphone vibrate motor?
how about home made voice coil?
magnetics are not easy
its a 1 magnet + 1 coil winding(like tesla)
no magnet, we can create it/ repalce it with other 1 coil winding
+ iron core
a speaker has exceedingly small gaps and very high magnetism
since human can hear ?hz - 22khz
so speed is 22khz
but what's the torque of a speaker? what is the positioning accuracy? what is the positioning range?
nothing to do with hearing its to do with the mechanical efficiency of movement
...small gaps, good to consider...
the gaps on my woofers are less than .5 mm
jepler, go made a experiment on broken HDD, to see its stability on a STATE, and the precise on POSITION
and 22khz is getting beyound EMC's cycle time, it cannot be controlled
... but force.. we need to build bigger one
even for a small CNC torque is in the range of .1 newton-meter. positioning accuracy is in the range of .01mm. range is 200mm
A4NDY: and when you put +-.1Nm force on the hard drive actuator, does it stay in position?
gaps on motor also abit the same
SOUNDCARD is the best choice
I have seen large voice coil mechs from IBM disks circa 1970
sound cards do not make servos
competition subwoofer voice coils are 4"+ in diameter
if you're looking for force.
how about big amplifier + big 'voice coil, home made'
your best bet would be a solinoid
...yes it is alot to consider
* toastatwork shrug
I was looking at it for a full sized mill
it's about the same thing
it was close to working in terms of numbers
the only difference is the gap and motor hang are pretty rigidly controlled in a competition coil
needed a neodinium magnet about the size of a football though
and I didn't want to stand next to it when it was in operation
i'm sure if you were careful you'd not have a problem winding your own.
The biggest issue was damping vibration and the like
JUST replace the PERMANENT MAGNET, with electric-COIL-MAGNET.... ;)
yes, some ripple on pre-amp would jold it
We were also thinking we would need to water cool the coil
Valen: in your design did you have a linear scale or something? I don't see how this works without position feedback..
yeah you know how I love the linear scales ;->
btw. is there any HOME-MADE linear scale ?
a ruler and a camera ?
(i really need it beside 'my common' encoder)
accuracy is hard to invent from first principles
The only way your going to even be able to mark it accuratly is with an interferomiter and a kickass laser
yes, the precision of position feedback should be several times higher than the actual positioning accuracy
factor of 10
and sound card dont cut it
i wonder to "print" linear scale like we use to SEE on our DESKJET PRINTER (canon,hp,epson,etc)
yay our mill should hit .01 mm accuracy ;->
printers are crapish
a TAPE from our oldy TAPEDECK or VIDEOTAPE would do !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
its a magnetic tape
u can read/write it using your oldy head-tape
not many positioning devices, especially not interferometers, have a 22 khz read speed
u still remember floppy disk right
how hast is it..
fast... is not too important for the buldozer cnc
the speed of floppy-head is still faster for our need
tape is easy to replace also
problem is how to GLUE it to its rail, and consider the space-gap if ure using floppy head
the idea of using unrolled cassette tape media for a homemade linear scale is interesting. The play rate is 4.76cm/s and the better media could store a 20kHz signal (according to wikipedia). That gives one cycle per 2.38um; in quadrature that gets you about .6um per edge. but how can you be sure you accurately recorded your 20kHz quadrature signal?
go see magnetic strip card for refference
jepler that's pretty much the main problem nowdays
getting nanometer resolution isn't particularly spectacular considering what's available, but getting it to resemble a meter is difficult
the STUFF u need is a FREQUENCY-GENERATOR, using a X-TALL
you mean "stuff", "frequency generator" and "crystal"
ALL RADIO HAVE IT... ;)
oh, and "you"
device to record the polse
to the tape
uh, where are you going to get a copy of a meter to calibrate your whole shenanigan
or even a reasonable facimile at much lower tolerances (i'm assuming)
generating an accurate 20kHz signal is not difficult, but how do you make sure that the rate the tape is passing under the recording head is 4.76cm/s +- .6ppm?
(that's .6um/1m or an error of one edge per meter of scale))
OK, FORGET WHAT I SAID ABOVE ABOUT FREQ-GEN, USE..
USE your already have encoder to role the tape using gearbox to gain more accuracy, BETTER than your original encoder
stretch would be a problem I'm sure
if you have any repeatable positioning, it's an easy matter to calibrate it (like screw compensation)
please do not shout
NOT REALL CRADEK
hahha, ill explain u how
(im so excite/happy... thats why im using big char)
you guys have pretty accurate rotary encoders, right? lap a wheel to a known diameter with a gage block and indicator, and use the wheel to drive the tape past the read head.
common this is a invention, small excite invention, so please is its useable, go build one and publise it on yourhomepage
here, how to
the streech problem
A4NDY, you build
all I'm saying is you can't trust magnetic tape to ever be the same length twice
yes me too, its just came to mind
cradek: yeah, I agree -- if you do anything but record it in place
cradek, UK company makes glue on strip encoders
The big problem with using a tape is you can only read it while its moving
cradek hahahahaha.... here we go my solve:
valen the same is true of other encoders
they're just pulses
if it isn't pulsing, you're not moving, so it's okay to assume you're in the same spot
yeah but if you are moving "really slowly" you will be getting ~0 volts out of your read head
at high speed you will be getting say a volt
so the size of the pulse is velocity dependent?
yeah -- a similar problem exists trying to use a stepper as an mpg
GMR read head = dc coupled
(i don't know jack about magnetic read heads, just curious)
the voltage yeah
just place the blank tape on your rail first, assemble your cnc, THEN the head that moving using old encoder move 1 way and write it pulsw
time measurement is fairly easy to do, so getting a drum to rotate at a set speed shouldn't be that hard with a gps synchronised clock signal
I can see that netting you .001mm markings without too much of a problem
thats way, we could ignore stech problem
Personally I think the old "ball bearings in a tube" trick is probably a better way of "inventing" accuracy
well good enough anyway
strech on placing the ape on
strech on placing the tape on
when you go into production you'd probably want to just apply the magnetic coating directly to a narrow plate, rather than start with a tape
hmm theres a question, whats the "width" of the track on a CD?
seems like there are lots of existing (working) linear scale technologies to choose from
heathen, other people invented those technologies
ours will be better because we did it
I'm thinking if you rip apart a CD mechanism and drive it just to the side of the hole (so its always over a data section) you could read the servo tracking bumps different from the data section
Valen: first figure I found on wikipedia says 500rpm 150KB/s
thats the linear size though
i answer the question for mr.cradek ...haha ...i do this cos other share their though, now its my turn
I'm talking about running radially across the surface
... ure talking about using CDROM as encoder
Valen: well, that gives 144kB/revolution, or ~4600 revolutions/640MB
yeah that sounds somewhere in the ballpark
it can't be as simple as that, though, because isn't CDROM CLV?
assuming one peak and land for servo groove and data your looking at .007mm per track
and on crappy plastic that expands with temperature
but aren't you limited to travel of under 1 CD radius?
The mylar strips in inkjet printers and their read heads
are probably a good place to start playing with linear encoders
JUST jumper the write laser if u wanna to do so
yeah under one cd width
as simple as that
was just a thought
cdrom as rotary encoder sounds more interesting to me
speed of WRITE is not important !!!!!
if only you had a cdrom that could track no matter which direction the head is moving
then the rest is ... u know the cd/dvd speed
now you've got a 4kturn absolute rotary encoder with a precision of 5e-6 radians
.. except for all the little problems that crop up when you try to actually do it
jepler put multiple readers one one cdrom
offset them just a little and you get direction
aren't there bit patterns related to LFSRs that allow you to determine both absolute position and direction? I have a vague memory of this..
Only issue your going to have as well is the data on a CD is encoded so you cant just write a string of zeros to it, and you might wind up with DC offset problems when you try to go slowly again
i'd imagine you could do something along those lines
a grey code of some description unless you were able to let it rotate some before getting an absolute position lock
Personally I'd rather make a mill (with magic) that runs the whole time from "first principles"
IE everything is based on light
interferomiter for length measurements, and beam following for straightness
yeah, the kind of scheme I'm talking about assumes you can move just a bit
you need to see a bunch of adjacent states to reconstruct the bit generator's internal state
yeah if you can do that you could encode absolute position along the rotation
whats a "first principles" way of measuring angle for a full rotation?
Just us FM or MFM encoding, clock bits are relative position between absolute codes
I think the best circles were made with worms and wheels, but via a few generations to average out the errors and the wheel gets sliced to distribute the error
thats a good one to conseder, IF we made encoder using a CD
'/DVD ... pulse of 1 cycle
I'm wondering if you set up a standing wave in an optical fiber around a "round" you could read that by looking at the leakage out the side of the fiber
last pulse and first pulse... would have a gap
measuring how out of round the round is would compensate that and is doable with an interferomiter
so buy a encoder rotary is cheap .... (linear encoder is expensive)
my solve of linear encoder (write on first cnc start) would not generate this such a problem
cos its a single line.... but we have problem on how to glue it on the rail
tape strip is plastic, rail is iron/metal
Yah, use the mylar strip encoder from a defunct printer
<archivist> printers are crapish
contact readers are crapish
floppy-head on tape strip
contact readers slow yes
AC coupled = wont work
counts lost below some speed threshold
floppy head will not read statically== useless for low speed
A4NDY, stop dreaming and spend some time seeing how real systems work
(archivist, i just know it from u) so we only have tape-head, contact readers
just a thought, im using ordinary encoder in today works
do u have any refference on 'low-cost' linear encoder...
define low cost
i have dificulty time on its demand
accurate and robust is common
A4NDY: what resolution?
there are some wire+spools for measuring
you strap it to one end of the axis, the end of the spool to the moving part, and it outputs position
it's accurate to some .1mm or so
0,1mm or 1mm
thats would do. :)
the length of linearscale 6-12meter is a problem on shipment...
(please i need suggestion, ill go check the answer on log tomorrow) :) ....thanks guys
heh voice coil and 12 meters in the same session....

I'm impressed with EMC2's documentation
actually, with pretty much everything in it
how come something this great exists and I don't know about it ?
must be because of my tendency to reinvent the wheel with microprocessors
I've reclaimed a P4 desktop machine I have running around
it has a parallel port
Xteven: Download the LiveCD, MD5 the ISO, burn at4x speed, boot off of the CD and run the latency test for 24 hours to see if your system will work well with emc.
24 hours ?
I will do that in the next couple of days
Xteven: You can use the system while it's running the latency test, actually better if you load it up use and abuse it as much as possible.
I plan to use it for EMC2 exclusively
is there come compensation for play in emc?
It's still ubuntu
well, maybe I can use it as a radio in the basement too
radio, surfing, email, video,etc
I'll do it all
ah backlash was the word, is there compensation for that in emc?
yes but dont have any to compensate
Yes, but mechancial correction is FAR better
.oO(is that what you get for not using cnc parts?) *ducks*
archivist: Oh, I thought you were saying YOU dont have any backlash.
I do and its a pain
it breaks tools
archivist: Well, in the words of LArry the cable guy.... GIT ER DONE
gimme money to git done
are ballscrews so expensive?
but you could counter it by having 2 thingies on the threaded rod that are forced outwards
* Jymmm hands archivist a pair of fishnet stocks and a tube top....
* Xteven is not making sense
leadscrew nuts ?
a double nut with preload
that sounds a lot more scientificy
I do that goodly

I'm looking for nice clear definition of "microstepping" (verbiage wise), any suggestions? Just a one-liner or two would be fine.
microstepping is dividing a normal step into smaller pieces, allowing you to position in smaller increments
I were going to add a (which is typically 1.8 degrees)
ohhhh, that was niiiiice anonimasu =)
but due to internal magnetics the partial steps are not accurate divisions of a full step
you beat me to the second line :)
thats the snake oil most dont see
I'm just trying to make a JS calculator, and thought it be nice to toss in a little description is all
anyone in here using solidcam?
is there some line-limit in emc? it woont show my model and paths in the preview
seems to load all the code fine, but nothing shows
zoom right out
Ive sometimes had to hunt for a dot or two when ive made a boob
it wont show
emc2 axis only
and for some reason it wont obey my home axis for Z
if you use perspective view it should auto zoom to the extents of your code
allways 0.500 or -0.500
or any other view
nope, no model there
just EMC2 AXIS that the software starts with
but running it is no problem
who in here had a G540 too?

when its set to 0 in stepconf that is
And THIS is why I hate working IT... http://thedailywtf.com/Articles/Slow,-Difficult-to-Code,-and-Buggy.aspx
well IF my home axis is set to 0, shouldnt it be 0 when homed? =)
not if you have some offsets set.
but if set like 10 as home, its 10
but 0 is bugging for me
ill try to play with settings some more
frallzor: stepconf changes the end of travel so that it is at least .01" (for inch machines) or .1mm (for metric machines) away from the home position
I can't explain where 0.500 inch or mm would come from, though
noone can =)
