how can i change the font used in latency test? can read everything except the headers and the Max Jitter (iirc) numbers.
tried all the font settings in System|Prefs|Appearance, none affect that dialog, all do change something visible on dekstop
so here's a stepper motor question, if I have a 6 wire unipolar and I only use 4 leads, what kind of setup do I have?
bipolar period i'd say
bipolar, the 'series' is unknown to the driver, and is only historical info for you
why is it relevant?
well I have my 6 wire unipolar stepper hooked up with 4 wires, was trying to figure out how I had it hooked up
and if there was a better way to hook it up for speed
there is only one way with a 6 wire motor
only one bipolar way that is
so would be bipolar series
or you can use half the coil
that works even if the coils are wound N-S-N
so if I did unipolar I would just ground the middle taps of each side?
and unipolar would probably run faster than bipolar series?
I'd guess probably not
with a loss of torque
that's the limiting factor
you stall when you hit the steep part of the torque curve
so, you'd really have to look at your motor data sheet
my application doesn't need very much torque
if the bipolar drive is crappy, and the unipolar drive is good, then maybe unipolar would be better. but unipolar has no inherent benefit over bipolar
potentially 2x the number of steps
icaro_ is now known as icaro
unipolar is just going to use half the coil if I ground the middle tap, yes?
half at a time
so it would change my stepping?
yeah a full cycle is 8 steps on a unipolar
if you count half steps, which you can do in DC on a unipolar
everyone recommends bipolar drivers now tho
what is the base thread period when there is no entry in the .ini file? ( eg 5axis )
i noticed that the latency test is base thread 25uS yet no one has that value in an ini ( checked from begin of configs up to HM2 dir so far )
tho the etchasketch and dallur's thc use 20uSecs
so whats the default when none is listed?
Calfin is now known as Calcite
Calcite is now known as CalG
Hi there, I was hoping someone could tell me if it is possible to run stepgen with encoder feedback? So basically a closed loop stepgen. The reason I ask is I have two Whedco DSP Motion servo controllers whith 10bit resolvers, these units perform very well, however I have been loosing some steps due to noise. I would like to bring the resolver feedback (quadrature out on the servo controller) into EMC and have EMC output extra steps if
any drift is detected. Is this possible?
I'm using a hostmot card the 5i20 if it makes any difference
I think someone has set up steppers with linear scales for feedback, but I don't know how he did it
here's a question for you though - if you have noise on the step/dir inputs to the drive, what makes you think you won't get noise on the encoder feedback?
It has been done, that why the velocity mode was added to HostMot2 (gtom at the EMC forum)
ok, that may be the person I'm thinking of
I wasn't sure whether it was set up as velocity mode and PID, or if it was just a "traveling following error" detector
SWPadnos, I'm hoping not to get noise on the encoder feedback because I have bought new cables with individual shielding on the paris and shielding on the cable as well as the encoder drive is rs-428 levels which the 5i20 supports
I was using a parallel port to drive the machine before
It was a closed loop system with a step motor and linear scale feedback
hello. I've got a working Rye 10'x14' table router, with OSAI controller series 10 (OS 8202) on it. It's one of 7 ever made... yay (not cool), anyway, I'm contemplating the switch to EMC2. Is this a good idea? I mean, the OSAI does work, it's just, well, very old (1998) and I'm having a hell of a time with the lack of network communication.
The_Ball, the 5i20 makes a big difference - it can generate steps and count encoders way faster and better than the parport
LaidBack_01, what's the interface to the morot drives (and other I/O)?
you can definitely use EMC2 to control your machine, it's a question of how much additional hardware you'll need to buy
The_Ball: If you are losing/gaining steps due to noise, can you drive the step/dir signals differentially? Are you sure its not a timing issue?
emc2 doesn't speak any network protocols, so if you have "smart" motor drives, or the existing control talks over ethernet, serial, SPI, SERCOS, or any of the serial buses, it will be more effort and/or cost to convert
(effort only if the smart drives can be used in a more basic mode, added cost if you need to replace them with dumber equivalents)
Hmm, I'm not sure on that. I'm not in front of the machine. I can tell you the OSAI provides an interface for 3 encoder axes, four 14bit d/a converters, a probe and a lot of safety systems
ok, D/A is a good sign :)
it probably means the motor drives take +/-10V control inputs
yes, they do.
four 14 bit +- 10V d/a converters
that's in the manual I'm reading.
that's good. pcw_home happens to have a company that makes FPGA cards and daughterboards that would probably work very well for you
I don't think they're 14-bit equivalent, but it's probably not needed
has an encover interface +D/A converter (0+1, 1+2, 3+4) expansion in the form of a piggy back board.
okay, as for the network part, it's my understanding that emc runs atop ubuntu linux - and since that's network aware, should that not be able to pull my machine code files from the machine I'm creating them at?
you can even run a GUI over the network if you like
and at the machine - you can have more than one running at once
pcw_home, I'm not sure what the issue was timing/noise, when you say timing do you mean if I was driving the inputs fo the servo drives to quickly? I really don't believe that was the case
okay, that's all I'm after is a way to get file from my cad/cam pc to the router so that I can work more effeciently
yeah - Ubuntu has a complete SAMBA client, so you can mount a Windows share if you like
pcw_home: which company makes the cards that I might be interested in. obviously I need to do a bit of homework here, but I'd like to have a working system.
[02:32:13] <SWPadnos> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Supported_Hardware
his is Mesa Electronics
SWPadnos: okay, fair enough, I'm pretty familir with linux in general, wasn't sure if the RTOS exensions took away some of the functionality or not.
Oh, cool, thanks!
yes they do - you might have to actually hit the power button when you want to shut down - the PC may not shut off on its own :)
at the moment, the liveCD we have (at linuxcnc.org) is based on Ubuntu 8.04. We're working on a 10.04-based release, but it will be some time after 10.04 comes out before that's available
yeah, I'm not an ubuntu nut, but know debian quite well, so I should be fine. Obviously there are reasons you chose that O/S, and it's a suitable system, so I've got no gripes about it. Not like i care to browse the internet, of have my router stream music while cutting parts...
three letters: LTS - Long Term Support :)
yeah, that's cool. Course, once it's up and running, I don't forsee changing much at all for 10 or so years...
if it works, don't fix it.
yeah, that's why we like the LTS versions - they're supported for 3 years on the desktop and 5 years on servers
till there's a reason to make it work significantly better ;)
there will be improvements to EMC2 in that time, so you'll end up needing to compile your own once you get past the 4 or 5 year mark
(I think we're just dropping packages for 6.06 on the next release)
ah, that's planning too far ahead for me. heck, I don't even have a 5121 yet.
well, you're getting in at a good time - just as we're getting to a new LTS version :)
there are folks who build debian packages or make Gentoo ebuilds from time to time
this machine is insanely complex. Uses a combination of pneumatics and electronics to do tool changes, bit movement, etc. It's different.
cool, sounds interesting
you may want a 5i22 ;)
(96 I/O points instead of 48 or 72)
yeah, I don't know, damn thing was built in Italy made out of french parts with an american controller... manual is in german and french and enlish last. lol
check out the Mazak case study. I don't remember if it's in the wiki or somewhere in the main linuxcnc site
time for me to get to bed. have fun reading :)
ok, sounds interesting. A friend as a pretty old knee mill he wants to sell me... I might just buy it to convert it first so I can find out what's gonig on
ahve a good night.
ah, here it is: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?MazakRetro
thanks. see you
oh, and the full config is one of the demo configs that comes with EMC2
now I'm leaving! :)
SWPadnos, part of the reason I thought noise wouldn't be a problem on the encoder was that the drives has a index pulse output which I thought would zero out the encoder every revolution, however it seems it's only looked at when using homing, not during normal operation, isn't that right?
in order to perform a threading operation on a lathe, do all I need to do is put an encoder on the spindle?
* elmo77 is a mill guy.
"pcw_home, I'm not sure what the issue was timing/noise, when you say timing do you mean if I was driving the inputs fo the servo drives to quickly? I really don't believe that was the case"
Timing can be wrong for other reasons, wrong polarity, insufficient dir change setup or hold etc. Also what version of EMC is this?
Yes index is only used for homing, but the idea of checking the count at index for a sanity check has been kicked around...
pcw_home, oh I started this with 2.2 I belive and I've been playing around with 2.3 and 2.4
well that's quite annoying, after moving house I can't find the mesa 7i33 card
That does sound annoying. Is it in the loft?
Asking because there was a firmware bug in the stepgen that could make it lose steps (but its pretty old before, 2.3)
Is the bug bad enough that he could lose the whole card :-)
I seemed to have timed out there... did anyone respond to my query about putting an encoder on a lathe chuck for tapping?
I wasn't logged in. What was the question? It definitely ought to work.
just thinking, a stepper is good for location of the tool but not the spindle or chuck. So... was wondering how to get tapping to work (on a mill or lathe) and I guess it would be with an encoder.
Yes, if you put an encoder on the spindle somewhere, it will just work.
It will actually work with one pulse per rev, but more is a lot better.
Sorry, ignore that, you can thread with one PPR, but not tap, tapping needs full quadrature so it can tell the direction.
I made my own encoder, it works fine. http://picasaweb.google.com/bodgesoc/Gibbs#5437112859354194098
(and the next two photos)
interesting trilingual sign
andypugh, yeah you gotta hate moving, at least my machinery is quite small, 300kg mill 500kg lathe
andypugh: photo 29 of 33, what are those blocks at the left?
elmo77: Just generic DIN-rail terminal blocks.
One wire in, one wire out, though further to the left lots of them are commoned with a strip in the central slot.
is that a tube covering the ballscrew?
#22 of 33
Yes, but only the top half. That ballscrew will be moving inside the column next week,
nice solid looking mount in #21
can a hall sensor be used as a spindle rotation sensing device into a Mesa "anything"? I have an Automotive transmission unit that puts out a signal when placed in proximity to the lathe spindle gears. The run in oil just fine ;-)
The mount is strong, but I have never managed to get the bolts from the back as tight as I would like, access is "difficult" to say the least
cstop: Yes, it will work into Mesa or direct to the parport. Put it on a gear and it can be linked to an encoder in counter mode for speed sensing.
But you will need to condition the signal to be +5V or a path to ground.
IT puts out both "above the line" and "below the line" pulses of varying magnitude, AC!
Ohh amplitude...that might be a problem
I'll need to look at the scope again, to see where it is at. You know these same sensors are found as "wheel speed" devices used for anti lock brakes. Rugged!
2 wire yes
andypugh: can't remove the mount, then attach the motor to it then reattach the mount?
Well, if it goes into a vehicle ECU it is 5V at that point.
elmo77: The problem is that the bolts go from inside the lathe bed into the block. It hasn't come loose for a whole though
I'll check the ECM/TCM signal conditioning...likely a transistor in the line
andypugh, img 21, I see you're into alu welding, I started that as a hobby a year back. lot's of fun when you get it right, not so much fun trying to get it right
Yes, let it switch a pulled-up IO port to ground through a transistor (the Mesa IO lines are pulled up by default, I think)
ALU with oxy fuel?
tig with argon for me
TIG. I look for excuses to use it
A nice machine with hi freq and a good pedal control makes the task easier.
did an oxy course, but we never got to do any alu
That's not my best weld, but it keeps the swarf out of the belt.
CLEAN CLEAN CLEAN! oh did I say clean? NO Dirty wire brushes!
409 mixed in HOT water is a good prep prior to striking any arc.
With gas, once the flame plays on the work, keep it there, to act as shield .
These welds turned out pretty good (by my standars) but they were easy welds http://wigen.net/hobby/f-16/images/stand_01.jpg.php
andypugh what do you mean "linked to an encoder?
Wired into an encoder module in HAL or the Mesa firmware.
The_Ball: nice plane!
not a separate encoder, but the encoder input right
Right, 5am, time to sleep
I'm just waiting for a plot to end. It's 51 % done. Caution! Pen plotter at work!
but it will plot without me watching it ;-)
what? computer driven equipment will keep working even when I am not watching them? That is insanity.
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-04-11.txt
The_Ball: what kind of fuel does that jet use?
someone reported emc wouldnt load a program.
I just had similar.
While trying for shorter BASE_PERIOD and higher velocities without any Unexpected RealTime Delays,
I had loaded the system with radio, video, gimp, glxgears... and had success ( no URTD ).
Then I edited the ini file for a shorter BASE_PERIOD, and loaded a new .ngc into the already running emc2.
emc seemed to be frozen loading 3DChips.
it wasnt frozen, it was very very slow,
I let it keep trying after marking the progress meter.
after 1/2 an hour the progress meter showed HALF.
I exited emc, cleaned up and rebooted, tried again.
3DChips loaded in a flash.
I THINK the load can be slowed by system load, but the execution isnt.
this in a forum?
sorry dropped out for a bit, cleaning up the garage to find that darn missing 7i33 card
elmo77, thanks it uses real A1 jet fuel with a bit of added turbine lubrication oil
what made you paint it like that?
elmo77, I didn't actually paint it like that, it's the "Tiger Meet" colors used for air shows/"meets". It came pre painted from the factory
top speed? ;)
haven't done a dopler analysis yet but should be +300km/h
just don't hit a pidgin :P

going on a bike ride today
pedal or power
going about 350 miles round trip
1840CC thats about the size of my car
yea same size as my wifes Honda but more hp
[10:49:13] <JT-Dev> http://i47.photobucket.com/albums/f163/johnplctech/HPIM1988.jpg
the one it replaced http://i47.photobucket.com/albums/f163/johnplctech/GW1500.jpg
probably weighs more than her cat too lol
I call it my bluewing
how many cylinders?
the amazing thing is the 1800 gets better gas mileage than the older 1500 did
the new bike gets 40-45 mpg
inline or V?
the 1500 best was 30-32 mpg
the cylinder heads are the silver part on the bottom
I always liked inline 6's
and by extension V 12's ;->
[11:04:50] <Valen> http://www.vapourforge.com/jake/general/hotness_scaled.JPG
4L straight 6 at the moment
I'm pondering what would be involved in making it into a V12
with the top half of 2 of the same engine
lots of work
well yeah thats a given
should be new crank, new timing chain bits, longer conrods
V rods maybe
like a harley two pistons on a common rod shaped like a V on the same crank journal
that's why harleys sound funny
I thaught that was a "saftey feature"
well thats what my brother keeps preaching to me
that they sound funny?
that they are stinking loud
yea, they usually are loud... most harley riders can't hear me coming and only see the blue flash when I pass them up
most of the bikers that I ride with keep the sound to a moderate level on their harleys and harley look alikes
is your ford a stick shift transmission?
did you know the steering wheel is on the wrong side?
its the right side!
yeah its manual
aparently when dealers sell them that commands a $3000 markup
its 10 years old
looks like a fun car to drive
i hate automatics
peak torque is 2500 RPM ;->
I'm wondering as well if its possible to make a crank shaft + conrod setup that is ball bearing based rather than slide
you might get a roller bearing to work but I doubt a ball bearing would.
2-stroke motorcycles use roller bearings because of the dry sump
I'm wondering how you actually assemble it, getting the bearing housing over the crank
assuming the crank is a single piece
I spose if you made it out of multiple pieces it could work
on 2-stroke bikes the crank parts are pressed together
the engine I was thinking will be pushing at least 1000HP
pressed bits might not be up to the job lol
yea, and pressure fed plain bearings can take a lot of load compared to roller or ball bearings
time to go get ready talk to you later
hmm hydronamic bearing?
its all pie in the sky of course, but its nice pie at least ;->
I was thinking of sticking one of the straight 6 engines onto a bike for my missus, just as a bit of insanity

can I ask someone who is using a NVidia card with the nv driver to post their xorg.conf file? I managed to hose mine and now I can't get GLX back
I do have one, but I just changed it from one I used with the closed driver by just changing 'nvidia' to 'nv'
so it's probably not something you'd like to see :P
not really :) my glx module is missing it seems. Failed to load module "glx" (module does not exist, 0)
celeron55, could you run "locate libglx.so" for me and tell me the path of that please
ah! apt-get install xserver-xorg-core --reinstall did the trick
thanks celeron55, the NVidia binary installer had overwritten the libglx.so file
omg I am an idiot! I've been turning my house upside down looking for a 7i33 card while I have been looking at it all along thinking it's the 5i23... not remembering the 5i23 is inside the computer!
The_Ball with smp the binary driver is fine btw
lots of graphical oomph
hi is it now posible to compile emc2 on karmic ?
or just is there a g-code viewer fpr karmic that suports emc2 code language
you can compile emc2 in simulator mode on any linux system. there are instructions on the wiki...
Valen, oh, I've been getting some "unexpected" realtime delays
jepler, you wouldn't happen to be around would you?
cradek: I lookt now into wiki but dif not find anything about simulator mode

i want to make a grid drilling with G91 G82 G98 X10 L5 the simulation does not show the drilling its only at the first drill
witch is G82 G99 Z-5 R5 P.5 F100
what i'am making wong
never trust sub programs to work or work the same on every machine
oh this is #emc not #electronics
i thought you were zee working on some random college cnc
emc does not suport M97 as Haas does
yeah i learned on a haas and had to unlearn a bunch of shit to work on other machines, heh
neato canned cycles, on that
the new has bunch of cycles
the old has also G150
that does the most
i tried checking haas g-code on emc, they are too different
doesn't your haas have a graphics console
our minimill had complex perimeter pockets with tons of parameters for cut depth/overlap and finish passes
but yeah ive done looped subprograms (sometimes w/ variables) on the haas, turbocnc, and emc, im pretty sure its completely diff on all three
like even the way o-codes are used
haas follows the fanuc macro-b standard
on the haas you can jump to completely other files
which is fairly convoluted
but you have to name the file by the o-code you put at the top
or some detail
instructor didnt even know you could do that
m98 is just sub call, g65/g64 are macros
i did like 4/5 the assignments with a single main code file
ok what is the best way on emc to get a grid drilling 10x10 drills 5 depth 25 spare X,Y
freaking people out with weird g-code is phenomenal
im like wat textbook that thing is expensive
you gave us the whole manual for the haas i just read that!
best way to learn g-code, hands down, is the manual
we had a haas turning center too, fun program at that school
i have books on g-code programming and they don't beat the manual
hahaha they got a fadal setup like 2 years ago
last time i talked to the instructor hes like ya were selling that thing
oh the new 5Axis cordinate drilling is very good as Heidenhein
toastydeath: yeah you need manuals anyway to figure out how to work all the auxillary stuff on a machine anyway
I have to get the manual from my new boss, he paid for really, really fancy controls on his machines
standard G-code shoudt work either
they have crazy insane g-codes that I've never seen that the teach mode inserts
standard gcode doesnt really exist
like, you can define paths and then call them later
with different tools and different roughing/finishing cycles
chamfering tools, etc
yeah if youre really good with those controllers you dont even really need CAM software to do most typical parts
yeah, and the teach stuff is incredible on it
like, G100-G200, canned cycle for every other situation you can think of
so if you know the g-code, you can use the conversational control to quickly hammer out the initial g-code and then edit it yourself to tweak it
i am really excited about this control, it's so awesome
plesa help with the grid drill on emc please
sealive, what you could do is call the peck drill cycle (g83 on most controls)
last job was a big german router from argentina or something, had a win xp controller =(
then call the 1st line to your first hole
was like, dos running in xp
and then call a subroutine that goes down the column
then have it move over incrementally a number of times
yeah what is it...
that's how I'd do it on fanuc
pcb-gcode for EAGLE pcb editor
will do g82 on every line
but wont put all the parameters on every line
wow i'd kill myself if it did that
so emc is like wat
one of my co-workers used to constantly change feed rates
so i have macros in my text editor to eat all these extra g82
so if you wanted to feed at 14 ipm instead of 10, you had to change every frigging line
find @ replace ftw
but that gets scary
tho really because its easy to seperate out f words, ive never had it fail
but i dont like batch editing big shit like that where like you almost cant practically check every change
i guess the program you're talking about doesn't have a post of any sort
haha like CAM editor gcode will always be a billion lines long with f words every 3 lines
and then you post the code and it pops up this editor like, HEY YOU WANNA LOOK AT THIS
like cmon rly
its a user script for a pcb editor, its not cam
so i use stuff to sim the gcode first
like the programming is good but the syntax is all fucked
like i wanna slap the dude wrote that output script like ITS FUCKING MODAL JUST PUT THE G82 ONCE
tho i bet alot of controller will read the next g82
and then just use whatever parameters were in the registers
that is standard behavior
or fairly standard, i suppose
heheh 'standard' is just a misleading word in context of gcode
that's why i added fairly =)
as in it's how fanuc behaves, so most people copy it
haas has some toggles you can pick what manufacturer it copies for alot of details, heh
sinmply does not work i got to programm all the 100holes +
sealive, i responded to you
you have a subprogram with the coordinates of a column of holes
then you call g83 or whatever, and pass it off to that sub
then when it returns, you have it move over however much, and call the sub again
then i can do it also in the programm if i have to use a sub
and I think Haas has a sub for bolt grids
if you look in the manual
so... just look in the manual?
is this a trick question
[16:09:39] <sealive> http://www.haascnc.com/pdf/96-8000.pdf
you have the manual, why are you asking us
i don't use haas if i can help it
so i don't know any of their codes
haha if i can help it
at WESTEC two years ago it was like everything was haas
they had a huge display area, and then hidden behind that was maybe 3 or 4 other machine manufacturers
and then literally every fucking tool vendor doing demo had a haas
every shop just getting into shit buys haas
hahaha like haas showed up with 30 rextra VMC and just started handin them out
they've got flashy controls, i like some of the features they have
but it doesn't make up for the horrible setup facilities they have and the utter lack of rigidity
minimills w/ turret changer pretty neat for the money, used
oh, no doubt
esp for a minimill, you aren't really going to be running a 5" facemill in stainless steel
i'm not saying they're terrible, they're just not my first choice by a wide margin
the two haas mills i'd own are the minimill and the tl-3
heh i have an open loop stepper desktop mill
i like the idea of a bridgeport-sized, full featured cnc
so any haas going slow is like haulin ass for me
hahaha we had an 80s bridgeport cnc
cool machine omfg the 80s UI on that thing
those things are old school
one line display
it had no shields
ok then i will write a simple python to get all the cordinates
so first semester, we loaded felt pens in a spring loaded tool
and drew shit on the clipboard fixture
hahaha @ crashing felt pens with a bridgeport
like, how to make funny plastic flowers with your CNC
my old school has a haas vm-1
i wish they had like, an OKK horizontal or some other old beat up cnc
because the haas is a show machine
it moves fast as shit but it can only cut aluminum with any expediency
and you had to clean it every time you used it
because it was a show piece for visitors
and the tools were all touched off god knows where, so it was always a nightmare
but that's not haas's fault, just nobody had any cnc experience at the school
but still, I would have preferred a 50-taper small horizontal
20 hp geared head
when i got to wood CNC job, the old programmer was using one burnt 3/8" carbide endmill
it was like, flutes up in the collet
and the offset was setup wrong
crashed four times and not reset
so all the programs had weird offset to compensate
none of his shit was usable
there was a 3/8" toolmark in the vacuum table
with a little charred bakalite spot at the end
like, the size of piece of letter sized paper
this boss tried to start me at $10
im like what you paid the other guy $18 to fuck your machine and not do any maintenance on it for 2 years
and hes like I HAVE GUYS WHO WOULD COME IN HERE DO THE SAME JOB FOR $10
"then get them"
im like hahaha (this is pacoima)
"why'd you call me"
that fuckhead, i got the shop on schedule and hes standing there like, NO MORE SALES SORRY
dude we called a contract guy he had for awhile
and hes like HAI DO YOU KNOW WHERE X FILES ARE
and dude is like, HAI DO YOU HAVE A CHECK
haha yeah seriously, what an asshat
and were on speaker phone, it was awesome
who calls a contractor for shit THEY should have
i got him to agree to wither $18, or $15 + $1 raise a month until $20
and got to $17 before he really just had like zero work
dude he called me, im like working someplace else almost a year and a half
HAI DO YOU HAS PASSWORD FOR CNC PC?
im like, no cmon rly
no idea what he was talking about
there wasnt passwords anywhere on that pc
the floor workers needed access to load random gcode and basically hit go and run away from the machine
i'd run too from the sound of it
the hail mary method of machine setup
that's actually how shit is running now
the tool offsets before i set them all up were just silly
like, how to crash your machine for sure
the fucked thing was they had a real nice setup plate for measuring offset
..at one time?
and some digital height micrometers
and a bunch of nice tool holders and an ER16 collet setup for small engravers
like what a dickhead all the shit to set tool height from the base of the tool holders was sitting there in plastic bags, shiny and new in his office
OH WHAT ARE THIS I DUNNO
hi am a 12 years old and what is this
neat machine tho
i just got a job at a place part time so i can do school full time
and they're not organized
i don't know how long i'm going to last there, they're not telling me what i need to know to set the machine up
like, having a print of any sort, for instance
"put these tools in the machine, and here is the program" is all i get
nothing about, oh hey, you might want to hang the part out the end of the vise so it doesn't carve said vice up
i've never programmed in CAM before, all my programming at my old place was by hand
HERE IS RANDOM LETTERS AND NUMBERS, MAKE IT HAPPEN
so they're going to have to show me their cam system
that will clear some of it up
yeah you cant look at cam code and make much out
its all super inline
most of the time theyll use G1 for drills
yeah, it's all weird shit
but i don't even know what the part looks like
there are no part prints
yeah its like trying to make itunes work open the itunes.exe with a text editor
they get a solidworks model from the customer
and then they just cam it
and like, if there's a critical dimension they write it down on a piece of paper
its easy to do when you have a good workflow going
solidworks dumps in in a few seconds then you just attach toolpaths to features
what freaks me out is that i am used to really cosmetic, high tolerance parts
so you can skip documentation step and prob go like 4x faster
and they don't even bother blending tools?
huge steps in the parts
they hand deburr if they deburr at all
yeah i dont really like the idea of working in production machining
too hardcore, everything too fast
do too good a job on your parts, get fired for taking too long
it's not even that
it's just completely disorganized
they don't MEAN to be this way
well yeah thats what the situation leads too
dude my apartment is a fucked up disaster
cnc machine in the dining room, oscilloscopes all over the carpet
i dont want it to be like this it just is
like a production shop isnt going to stop for a month and go OKAY WAIT EVERYONE CHILL OUT
LETS CLEAN UP, GET SOME SHELVES, ORGANIZE
this a new shop staff
yeah you know
is the other part to it
so i guess the bottom line, i don't know how long i'll be there
but that sucks because it's one of the few places looking for part time work folks
a lot of people were interested, but not part time
like, machine shop your life kinda depends on other people not being stupid and fucking up
electronics lab, not so much

messed up the finishing a bit, but its only trial anyway :)
but all in all, pretty ok
say what what
[16:49:32] <Jymmm> http://sfbay.craigslist.org/sby/tls/1686885974.html
a mechmate with a 2kw spindle, how much can I mill in a single pass do you think? feel free to suggest any feed from 0mm/min to 10000min/min
*in alu that is
frallzor, how long did that take? looks pretty good
but I messed up some when I forgot to adjust Z after tool change =)
discovered it too late =)
and when I was going to redo all values were off, so I just had to guess where 0,0 was
tried to oil the work :P
wow, impressive speed , must been a lot of meters of motion with 6mm ball
gives it a luxury cardboard feeling to it
3mm ball =)
cant say Im not satiesfied with the build =)
how did you make the program?
its a bit odd too
* frallzor basks in the light of his grace

Spindle motor??? http://sfbay.craigslist.org/sby/tls/1687030893.html
1700rpm is a bit low
single phase, cant vary the speed

know if the spindle, you can set a ramp?
you will have to do it yourself in HAL
I have not found a way yet
look in the integrator manual
there should be a HAL block which limits the time-derivative of its output
you hook the spindle-output from EMC to the limiter
and the limiter output to your spindle hardware
okay I'll try
* archivist sets his ramp in the vfd :)
I do not use inverters
but dc motor
frallzor: dude, happen to be here?
billykid2: are you driving your dc-spindle with a servo drive?
with limit you can at least limit the commanded spindle speed
What should I put in the file hal?
im pirating =)
frallzor: I was curious to know what your acceleration and maximum speed settings where....
I can cut at around 13000mm/min
[21:17:39] <frallzor> http://hotfile.com/dl/37432319/5807e9e/CAMWorks.2010.SP0.0.part5.rar.html
bah wrong link =)
[21:18:23] <frallzor> http://pici.se/p/large/KOpKehkow/
frallzor: I cannot cut that fast yet... I am cutting at 8000mm/minute, 5 mm in MDF with a HSS bit
this was done with 13000mm/min at max
and around 22000mm/min2 or what ever the velocity setting is called
I noticed that my dewalt router at high speeds starts to sweat a lot :)
crap... you are at 22000?!?!?!.... Hmmm I have it 1000 right now
2200 I think
Ahhh ok... yeaa that makes better sense... I need to se eif I can crank it up a bit then :)
and 300 set in the box aboce
I did try to plish my racks and pinion yesterday, I think that helped to get some of the resonance weirdness out
yesterday I made a little wooden thingy for my bread hobby.... to let the bread rize in, I only need to make new files to mill at both sides, it went fairly smooth I must say
yeah my little test went ok too, besides messing up Z for the 2nd program =)

can I ask some basic Linux Terminal questions here? Just two simple ones ;-)
Ask, if someone can help, they will.
Jymmm First a thanks on the "Battery" problem the other evening, The power management (I forget the name AP,,,,???? ). I removed the driver, and everything works fine. I need to reinstall a driver to return power management, but that's trivial.
Now question 1 If I type a command such as "Man" and open the pages, How do I get back to the prompt?
just now, I have a terminal open, and have called "TOP" The display is filled with information regarding applications and memory usage etc.
And I can't get out ;-(
except to close the terminal and open a new one....
no "q" ;-)
cd up the file tree? cd //? or ?????
dot dot? I thought I tried that....hmmmm?
Thanks. I must have too much on my mind and not enough under it ;-)
Now for a tough one... I need a zero to 3 or 4Kohm "industrial duty" (Well at least oil resistant) potentiometer for the lathe VFD speed control. I have a nice 2K, but it's a bit rough on the control sensitivity. Suggested sources? I looked at a few on line electrical houses. Nothing caught my eye.
That would be a 1 turn, ten turns would be sooooo slowwwww ;-)
dos up through some versions of windows allowed cd.. (no space) linux requires cd .. (It took me a bit to figure out) ;)
that's cd spacebar ..?
[23:36:59] <aystarik> http://www.alliedelec.com/variable-resistors/potentiometers/?N=4294824533+4294828195+4294901059+4294911953+4294958880
allied, I'll have a look
seems like I should really want a 5k unit. Only 1 at 3.5 K the spec suggests 3K, but I tried a 10K 10 turn that did the job, just that it was a ten turn. I am sure the 5K or the 3.5 K will do. Perhaps get both. Thanks
another Terminal question?
how to send a simple text string command to the serial port device? In DOS echo would do...
Sounds like that could be read with a resolver input device:
pcw_home: we have a function generator - going to send some signals down and see what comes back.
Yeah, I think that would be instructive...
we never had a positioning issue with the old controller (that we know of) so it would be cool to get the old scales running again.
Certainly a tough scale
pcw regarding the cat instruction is the form "cat <text to send> /dev/ttyS0" ?
Yes like that...
cat (filename) > device
echo is like you said
Looks like maybe the original reader squared up the read signal and interpolated with a counter
well, cat did not work, the kitty wants a file, not just text. I have been successful using cat to send files to the serial port.
yes echo for command line string
