I seem to be pretty clueless .... strace didn't go anywhere
$ /usr/bin/strace /usr/weber/bin/synergy > trace.out
produces command not found
OK after I finally get the path right I still get command not found
is synergy a completely standalone program, or does it need anything in the path?
(for example, does it use any libraries that they distribute?)
I think it uses lib32
I'm trying to run md5sum on the disk but can't get the cdrom syntax right
is /usr/bin not in your path?
that's a little strange
not a very clean install
did you reinstall or upgrade?

oh hey, fligths to Bangkok only $1190
but who wants to join the revolution
you saying' you want a revolution? :)
I want to go ride my bike in India
seems to me there has been rioting, etc in Bangkok
oh. maybe that's why the flights are cheap :)
where are the default paths set?
(I wasn't looking for flights there, I just got a low fare update to BKK)
I thought I saw something about flights only taking off from military bases
/etc/bashrc or /etc/profile maybe
maybe I have the wrong country

dave_1: what machine are you working on?
amd 64 dual
iron I mean
this is a desktop system ... non-rt just for sim and cad
I see, you're here for general linux support :)
eventually this cpu will go on the lathe
but of course will get rt for that
that's quite a list, but the executive summary would be much shorter
I'm going to set up my router at work so I can use Pro/E and Solidworks from home
that looked like the executive summary to me :)
have fun with that
have you tried it from linux?
I think a friend tried to set it up for SW, but it was just waaaay too slow
that could be
could be wrong, and it could have been a while ago. I don't remember the specifics
you can lower the resolution
sure, but I suspect SW looks like crap at 1024x768 or below :)
you'd probably have a 100x100 pixel work area
it doesn't matter so much what it looks like
why so small?
menus, toolbars, feature tree, property pane ...
the folks at my old company run dual 30" monitors on all their CAD stations now
it's likely overkill, I'm sure one would do ;)
I'm using 24", it works fine
I would have dual 24", but I have no place to put them
in fact, I may have some extra 20"
many apps are made with high resolution in mind, and they don't always work well when used on lower resolution displays
let me know though, I'm curious
when I said resolution, I meant rendering resolution, not pixels
oh. well on NT, 2k, or XP that should be fine
I've never used remote desktop over a wan, just a lan
and it can be slow on a lan
that thread you linked is funny, the guy asks how to learn html/css, and ends up getting a list of every linux software available
I noticed that the CAD apps didn't have much to do with Adobe
whatever, the list was good
good list, but I am left with the question "are any of these worth my time?"
I guess it depends on whether you care about using a Linux based CAD program
and how you value your time against that
sometimes there just isn't one available that is worth using
I suspect there's a good analogy with Eagle
I can't use EAGLE, and I have little incentive to try because I have Altium
eagle probably keeps the quality of the free stuff down a little
and know how to use it
but there are a lot of people who have taken the time to learn it, and they can do a lot of what I do with Altium
is Altium a new name for something else?
it's a PCB design suite
I know, just curious if it is renamed
Altium bought Protel and Tango way back when
and I think P-cad also
so I think maybe Protel turned into Altium
I wondered where some of those went
yeah, I think there's Cadence, Mentor, Altium, and PADS
Cadence bought OrCad I think
there isn't much else in the really high end market
there are some others though, Proteus is one, there's another I can't remember that I've seen
there is a limit to how many people are going to spend 4k+ on a package
and the MCAD market is pretty similar, you have CATIA, Pro/E, and SolidWorks on the high end
spending that much, you want to know that the company is going to be around
then a slew of mid-range products like TurboCAD, Rhino, etc
Aaltium is $10k
I think a full solidworks package would cost me almost $10k
sure, if you include FEA, the upgraded photorealistic renderer, and maybe their stupid versioner PDMWorks
with the first year of maintenance thrown in?
no support incidents, but upgrades for that major version
support is another $1800/year or thereabouts
and it gets you the major version upgrades (about 1 every 2-3 years)
do you get that?
I did this last time because I wanted some of the features of the 08 version
so you don't have to have maintenance every year?
no, but they will charge you for the prior years if you want to get the upgrade :)
sounds potentially expensive
or there's an upgrade price, but it's about the same as a couple years of support (so you might as well get the back support, since you then get the support incidents)
Hi, A question about rigid tapping. What kind of spindle drive and motor did the Mazak at the EMC workshop have?
just a basic vfd
to a basic AC motor
What was the control input? analog?
yes +-10V analog for spindle speed
EMC2 can rigid tap with any spindle that can make a nice smooth reversal
for instance my lathe has a 2HP spindle motor on an automation-direct VFD
Do most drives have analog inputs?
VFDs do - I'm not an expert on the various kinds of drives
Yes I mean VFD. That is what would work for most 3 Phase spindle motors
All I need to do is have a VFD and an encoder.
right, encoder with index
the vfd's I've looked at have +/- 10v
The modbus interface is not fast enough?
it would probably be fine but I have not tried it. modbus support is very new in EMC2.
Yes SWP was working on that.
my VFD has 0 to +10V and digital inputs for fwd/rev
the command rate for modbus should allow at least 50-100 updates a second
at least for the GS2, at 38.4kbaus
it would be perfectly fine then
cradek: does the tapping work with digital forward/reverse?
it works from encoder feedback, which is realtime
it doesn't care what it takes to reverse the spindle, just that it reverses pretty smoothly
I believe that is more common
right, EMC just follows the spindle with the moving axis while it reverses
the reversecommand could be slow, but it would affect how much too far the spindle goes before stopping
all spindles take "a while" to reverse
hmmm. maybe 50-80 updates a second. I think there are around 50 bytes per exchange
Why do I need an index pulse on the encoder. dosen't EMC only need to know the spindle speed?
that's where it comes from
you must know the orientation of the spindle
you need a full encoder?
If it is a tap maybe I don't care where the thread starts
the current implementation waits for the index before moving (I know for lathe, I think for rigid tap too)
so multiple passes line up (think lathe threading)
you can even peck tap!
OK that makes sense.
that is pretty cool
how does he charge the thing at the track?
fast car though :)
john_f: it's neat to see on a part with a lot of tapped holes how the entry threads all point the same way
john_f: minor correction to your original question
the mazak has a DC spindle motor
not a DC servo, just a 5HP or so DC motor, with an SCR based drive
from a control point of view, it works just like an AC VFD
0-10V speed ref, etc
hello all i am new to emc. In efforts to do my homework i have been doing a lot of reading. Am i correct in understanding that i/o is mapped from physical to emc variables thru HAL
dose anybody know what seems to be the prefered method of interfacing to servos i have been looking at the vigilant pci board
everybody has different preferences
I seem to prefer the Mesa
but I could prefer the vigilant if it was cheaper
i want to use drives that take a +/-10v signal is the mesa capable of providing that the cost of the vigilant is steep for me
I like Mesa because the maker is an open-source supporter
yes, mesa can to +/-10V
Guest898: yes, there is a daughtercard for +-10V output
you need the external board for that
7i33 interface card, has 4 encoder inputs and 4 +/-10V outputs
the 7i33 is under $100
well thanks that makes that easy
mesa lit was unclear on analog
I'm not a big fan of their website
I used mesa for my latest conversion and I will also use it for the next one
any special coding to do with the mesa, or just load provided firmware
just load provided
in the EMC2 distribution
a common setup is 5i20 + 7i33 + 2x7i37 -- that gives you the analog+encoder mentioned above, 32 isolated inputs, and 16 isolated outputs
what are people using for interfacing mpg's
yes, and a simple mill might only need half that IO, saving you one board
you can use certain additional I/O as more encoder inputs
anything that reads an encoder, like mesa, or even software encoder reading on the parallel port
if you have a 3 axis mill and a 4 axis 7i33, wiring it to the mesa is easiest
dose emc have a provision for a mpg i assume it dose i just havent dug in enough
yes, it does
you can do lots with external encoders - jog, feed override, spindle override
cradek has set most of those up on his lathe
how dose it handle incrmental magnification
I'm just working on laying out a front panel for it...
Guest898: yes you can change the jogwheel increments however you like
right -- for instance, you can use a 4-position switch to select one of 4 arbitrary increments. Maybe .01, .02, .05, .1; or maybe .001, .01, .1, 1.0 -- it's up to your configuration
or you can set it up to use a key on the keyboard to choose jog increments; again, the increments are up to you
yeah i have a ton of handwheels with axis and incremental selectors. they are all graycode switches so i just planed on decoding them in ladder logic
here's an example of putting a specific mpg on the parallel port: http://linuxcnc.org/docs/html/examples_mpg.html
in emc there's a special component (separate from ladder logic) to turn graycode / quadrature into counts -- that's what you'd want to use (if you're not using the encoder function of the 5i20 card)
no the selector switches are gray code
the handwheels are fanuc push pull
yeah ladder would be a good way to do that
Guest898: if you give me one I'll happily help you get it set up and working
I was not reading what you said, I was thinking about how quadrature = 2-bit graycode is all
heck, I'd probably help you either way
oh well, worth a try
send me you address i have two many to count. I do safety upgrades to CNC Machining centers i get them all the time
the pendant in that example has a 4-position switch -- I think one position is labeled "off" or just blank -- but I'm not sure if it's binary or graycode. with 2 inputs mux4, it doesn't matter -- just set up the right relationship between the inputs and you're done.
dont worry i plan on needing a lot of help lol
email sent, thank you
any suggestions on a board cpu ram combo
I'd happily pay for shipping too, let me know
I've used anything from P3 on up
will do i will probably just ship it from work
Guest898: you are in UK right?
got your email no toronto canada
ah, "ministry of labor" threw me for a sec
LOL i was thinking that my self
fenn are you from the uk
Guest898: what kind of machine is your retrofit?
brand new right now it's planed to be a 4'x4' gantry with about a 24" z axis i may also add a 4th rotary axis
drives and motors are allen bradley ultra 100
neat. for wood or metal cutting?
hope fully both i plan to over kill the structure
bosch linear rail with rolled ballscrews alum plate frame
I bet that much aluminum plate will cost a small fortune
actually i let jobs i do pay for it most of it i will use standard bar sizes and stay away from cutting plate
i do have a frist 9"x42" mill i may convert if this works out well
has anyone tried to do some sort of tool offset probing with emc to automatically measure tool offsets
Guest898: yes I've probed tool lengths
what did you use
in the upcoming EMC2.3 you can even write to the tool table with G10L1, so you could run a program that probes all your tools and writes the tool table for them.
I used a simple microswitch mounted to the table
renishaw makes some nice probes just for this if you want to spend 1000x as much for 10x the precision :-)
this is too much i wish i new about this two years ago
yeah i've used those probes before
ever tried a ruby switch
no, what is it?
a precision prox switch i can send you some info in the morn
verry repeatable for a simple switch
I'm always curious but my budget usually doesn't get me anything with "precision" in the name
i hear you i get all of my stuff on it's way to the bin
sounds like you have nicer bins nearby
just the industry im in machines get rebuilt i take what may be of some use in a year or ten
Trying to rebuild trunk, updated cvs, make clean, make -- got this error:
make: *** No rule to make target `/home/emc_from_cvs/head/src/hal/drivers/mesa-hostmot2/hm2_5i20.o', needed by `/home/emc_from_cvs/head/src/abs.o'. Stop.
I've seen before but don't remember solution. Any ideas?
did you do cvs update -dP, or just cvs update?
just cvs update
redo that with cvs update -dP
maybe you are missing a directory otherwise
ok -- I'll try that -- and Bravo! for finding the seldom-seen arc bug
it showed up 3 times in 2 years - I was very happy to find it.
cradek: did you ever see it in person?
skunkworks: no but I was able to trigger it on purpose by initializing the uninitialized data to something nonzero
that was what made me confident that I had found it
it is SO rare that it will be hard to know it's fixed
but I think it is
* skunkworks actually thinks it is impressive you figured it out without 'being there'
I wonder if it happens eventualy on machines that are left on continuously
SWPadnos: I think that's possible
I bet Stuart leaves that machine on a lot more than the average EMC user
those are stack or heap allocated objects, so I wouldn't think an errant pointer would cause the problem
skunkworks: all I did was look at the places where I thought that behavior could be caused, and when I was sure it was right I went on to the next one, and eventually I found a problem - then I triggered the problem like I said, and the bug appeared
fenn_ is now known as fenn
i joined twitter and i don't know why
cradek: update -dP worked -- thanks, a lot of dirs had been added since my last update/make
it's always good to use -dP
lesson learned i hope
I put "update -dP" in my ~/.cvsrc and then it always remembers for me
i've built a kernel with rtai and acpi enabled so i can suspend on a laptop i use for testing (no machine attached). now i'll try to get emc working with this kernel
you are brave
so far so good:)
I leave the dahlih on all the time
ok, can you get back to us in a year or two and let us know if the problem is fixed? :)
you can be assured - if it is noticed again it will be revealed :)
stustev1: jonE has a forum on cnczone.. You should go say hi :)
[04:07:44] <skunkworks> http://cnczone.com/forums/forumdisplay.php?f=428
cradek: thanks for the quick response with the 'black flag' bug killer:)
it's a relief to have that one fixed
I do NOT like bugs that cause wrong motion
very bad very very bad
the main problem is Clyde has lost some confidence with the machine
I can't fault him for that
the day before the malmotion happened Clyde came to me with another 'problem'.
He had center drilled some holes, copied the program section to the bottom of the file to drill the holes, the drill motion was off the table in X and Y.
He was claiming the H02 was the culprit- somehow the machine was using it wrong
G91 or some coordinate system snafu?
SWPadnos: you are too quick ( G91 )
it's all I know :)
I went back to look at it with him. He had done a g91g28z0 at the end of the center drill cycle and hadn't reinstated G90 yet
It was a very easy fix but his not bothering to look any further than 'the machine is messed up again' is unfortunate
I'd expect the AXIS preview to warn him of that problem
This will allow him to gain some confidence now
the code didn't run did it?
(should have had soft limits exceeded error)
the preview did - he uses that a lot as his projects are one part or maybe a few
do you guys have the soft limits set artificially wide?
he hadn't tried to run it - he could see the motion way out of place in the preview
red numbers = bad :)
well, deep red that is
the soft limits are set to keep the machine from hitting a hard limit
yay, the preview
I will have to say Clyde is not a CNC operator - he is a very good manual machinist - I wanted him to learn it (he wanted to learn it) so I could get some feedback from a machinist
at least he didn't complain that "it took off on its own" when he ran G-code :)
he KNOWS how to cut parts so problems will more likely be real problems instead of machining errors
that is a good thing
his complaint was 'the motion is clear off the screen'
well, let's see how he regains confidence in the machine
he has learned it pretty good - he likes the keyboard hot keys - his finger just fly across the keyboard
funny - there was a guy I went to high school with who could type about 6 WPM
with his index fingers
he was a one-finger typist, but damned fast at it :)
err - 60 WPM
where'd that 0 go?
we don't hire secretaries that just use one finger to type with - they are a hunting pecker ;)
did your one finger miss the 0?
it must have :)
my pinky is slightly frozen. I'm in the basement with the heat off, and it's around 10 below out
it's a good thing my laptop puts out a bit of heat - we don't have a cat any more
it is short sleeve warm here this evening - prognosticators tell us we should have 2 inches of snow on the ground by noon tomorrow
what happened to your cat?
prognosticatos tell us it'll be 45 degrees in a few days, but we have an inch of snow on the ground now :)
oh, he died a couple of years ago
my wife is allergic, so we didn't get another one
do you need another cat - we have three - I think these are hypo allergenic :)
I like cats but three are two too many
cats are good for one thing
be careful now
you only say that because you have 20+ birds
SWPadnos: Nope, said it a long long long time ago
do you have a bumper sticker that says 'I like cats - they taste like chicken'?
oh. in that case it's because you're an asshole :)
you folks are lucky my mother isn't around
68 years old but she'd still thrash you for talking badly about cats :)
SWPadnos: It's the only animal that hunts for sport that I know of. I don't like it when humans hunt for sport either... and they can be dog food too (if they can bury the bones that is)
humans are animal too
ok - that's true. house cats do tend to have fun wth other animals
and those humans that hunt for sport can be dog food too!
I'm an equal opportunity offender.... I dont care who you are, I'll offend ya!
only one of our cats will do any hunting - she always brings whatever she catches and offers it to the whole family - then she eats it
Now, if you can tell me how to get the dman subtitles into a AVI, I'll be your bestest buddy!
she doesn't hunt much anymore - she is 10 years old - when she brings something now I think it was probably dead already :)
we had a cat that lived to over 20, he was still out catching birds when he died -- only 3 working legs
I will miss this cat when she dies - she meets me at the end of the drive when I get home, she sits in my chair when I am gone, she sits at the table with me when I eat (I don't feed her from the table)
10 is a young one, especially for a non-neutered male
I am a non-neutered male :)
a friend has a cat that recently lost control of one leg (then got it back, lost it again, and I think got it back again)
you're not 10
a little more :)
this cat catches at least one thing per day, and eats about as much as possible
which makes it fun for me when I take care of the cat - looking for rabbit or squirrel (or frog ???) entrails around the carpeted condo
SWPadnos: so, that's why you like to eat so much... snacks all around
no. just a high metabolism I guess
that's ok, I enjoy finding new holes in the wall
...to eat at
I wonder how they get all the lights you need plus brakes into a 4-prong connector
oh, not that - sorry
I like holy walls too :)
gnd, left, right, brakes
or chassis + left, right, brake, rev
yeah, I guess the expectation is that you'll flash the parking lights or something
it's 46 out here, and I have a date with a pillow!
oh right. duh!
the brake light contact can also activate the brakes themselves (or vise versa)
are you talking about car lights?
yeah - trailer lights actually
do they actually have separate brake/direction lights?
actually, that would be 4
well, the trailer actually has brakes
so that's 1
left and right are needed for blinkers, and can double as parking/marker lights
so I guess that's all you really need
do they have parking lights? I don't recall seeing that
I had just forgotten that the brakes and the brake lights always go on at the same time (ideally) :)
that's the preferred option
well, driving lights on the left and right
which are the blinkers, just left on all the time
[05:09:44] <SWPadnos> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130273244982
expensive, but looks about perfect for moving machines around
that's what I'm talkin' about
I rented something similar for my mill
the trouble with rentals (and that one also) is that they're really heavy relative to their load rating
so idiots don't destroy them
as an idiot, I approve of that message
the pickup I was towing it with was a monster too, drop tailgate
cost me a tidy sum to drive 400 miles
it is funny that you can't get a pickup that can take more than 1-1.5 tons, but the big ones are rated to tow like 14000 pounds
I can imagine
this is a good time to buy a long distance lathe. I can afford the gas to pick it up
between that and the forklift it was at least half what the mill cost
I paid the guy I bought the lathe from to deliver
best $300 I ever spent
I lucked out. a friend wanted to get a lathe on the same route as my mill, plus he had a coupon from Ryder for a $79 2-day rental (which was avtually 3 because it was a weekend)
so for $300 or so, we got the truck, gas, and a hotel
was it a closed top truck?
and were able to pick up two machines, one in Buffalo and the other in Syracuse
yep, panel truck
you can load those with a forklift just fine
the ones I've rented didn't have reasonable tie-down options
unloading was fun because we don't have forklifts
my mill weighs about 5k
we got load bars from Ryder
what do they do?
and strapped to those, plus the base of the vertical beams
they're sturdy beams that you latch across the truck at strategic points
they keep things from sliding front-to-back
I didn't know that was an option, every time I rent it's from incompetents
they're about a 4x6" cross section of aluminum tube
U-Haul = incompetemt
ryder still owes me $40 from my last move
the Ryder people also didn't know where they were - we had to show them in the back room :)
they said, "oh, we don't have a hand truck, you can go drive an hour and pick one up yourself"
but at least they had them
cha-ching! mileage charge
and they wouldn't take the thing off the bill, they said take it off when you settle
actually, that was the other nice thing about this - the mileage was free
yep, of course
then they don't know what the heck drugs you're on
of course they wouldn't do that
I'm probably lucky they didn't charge me for losing it
"what hand truck? you guys don't rent those"
so I drained the oil and drove it for 10 miles
I just wish I had
although I did forget to retract the ramps on the car hauler and drove it at least 5 miles with them dragging
boy, did I feel stupid
good sandpaper, that asphalt roadway
concrete is even better
around here it's almost all asphalt
but concrete would cause more sparks I think
oh right - PA
it is strange that in the northeast we use asphalt, but in the midwest they often use concrete (like Wisconsin and Minnesota)
they get just as cold as we do, so that's probably not it
I think cold is ok, it's the oscillation from one to another that causes concrete to die young
they have permafrost, and their big problem is during the spring thaw
stronger is better, asphalt roads are weight limited during that period
hmmm. concrete is brittle compared to asphalt, so the freeze-thaw cycles are a problem
we have a concrete interstate nearby, it is getting a massive overhaul after 10 years
oh. 10 years wouldn't be bad for up here
not too bad anyway
last year, they decided it didn't have good enough drainage, so they had to cut across it, this year patching
60 miles of one lane interstate is a fairly good psychological test
turns out most people are insane
oh, is this the stretch across the west end of the state, between NY and OH on I-95?
I know they've been working on that for a couple of years
you are thinking about I-80? I-95 is east
the connection between da truway and Ohio, through Erie :)
80, 90, whatever
well, if it's anywhere Ohio, it's broken
I lived there for 6 years, and the concrete there is shortlived
actually, they're working on that road in both PA and OH
do you watch "30 Rock"?
oh. too bad, it's a funny show
they had an episode where they portray Cleveland as paradise (especially compared to New York)
it was pretty funny
that does sound funny
although Cleveland isn't too bad
Tina Fey writes and stars in it - it's damned good
seems like red leds have been left behind as far as power
hmmm. I think I have some 130 candela ones
(yes, candela, not mcd)
those ratings are fairly arbitrary
they're pretty damned bright
I got a lot of LEDs from a couple of eBay sellers in Hong Kong
do they require a heat sink?
no, they're not the 1, 3, or 5W class like the Luxeons
the white leds seem to be rated in lumens
some are now, which is good
I want to build a light for my bike, front is good, rear I'm not sure about
oh. if you're looking for visibility and not illumination, these would be fine
they're low power - I think 3.7V and 20-100mA will do it
2 or 3 will light my office enough to read by (shining at the ceiling)
I have something like that now, bought it from lowes
16 bucks, 4 AA cells, 10 LEDs
then you probably don't need to build one
I have a hub dyno, so I'd like to use that for power

I have some old luxeon stars, wonder if I can just replace the emitter
no, the emitter is what makes it a Luxeon :)
the star thing is just a heatsink
I know that, but the emitters are outdated
ah. you may be able to do that with a new Luxeon
now that I think of it, I'm pretty sure people are now replacing their old luxeons with crees or seouls
yeah. DigiKey seems to only have accessories and lenses for them - no actual LEDs
last time I looked, mouser had more options
but it's cheaper to get them from HK
570 - 740 lumens
but not red
at 2.8A, for not more than 5 seconds without heatsink
it is nice and small though
true, I couldn't pedal the bike
now I see why the P7 flashlights cost $50
570 lm is a lot - about like a 30-40W bulb
People with 150 lumen bike lights report drivers flashing them because the light is too bright
now you can get up to 800 lumen, you have to dim them
oh yeah, I can imagine
oh. bedtime. good night
hey night owl ... SWP ... still around???
he said he was leaving, but you never know
well he is still loged on but that may not mean much.
btw hi eric
after pulling out most of my remaining hair I finally downloaded the rt from linuxcnc.org and installed.
does it work?
at least it will boot from CD to install.
Got synergy intstalled and it comes up. :-)
not really tried anything yet.
good start anyway
need to add the old disk as hdb and copy files across
will know tomorrow
where are you
eric_ul .... where are you
ah ... so it is early morning. .... another night owl
nice if you hold up
no one bothers you
probably not good for me
If I stay up til three it makes me grumpy, so I should be off
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-12-09.txt

only 6 more inches of snow over night.
maybe 1 or 2 more today
I love winter
* skunkworks_ has to get some new ski boots.
* archivist sitting here in a fridge
winter is only nice if heating is provided
skunkworks_: there was supposed to be a decent snowfall here but it didn't amount to much
The snow is light and fluffy. Not a real issue at all
* archivist want warm sun
sod.. got beat for a couple of auto-collimators on ebay
* skunkworks_ thinks of collimators for telescopes
machine alignment scopes
I didnt fight hard for them as I have an angle dekkor which is the same almost

it's photoshopped ;)
* skunkworks_ is kidding
Does anyone know why EMC doing g0's would ignore my MAX_VELOCITY in the config file?
Seems to be trying to go rather faster, which my steppers really don't like. :)
what behavior are you seeing?
Well, I've got the mill set to a maximum of 12mm/s (using the stepconf wizard) but if I do a longish G0 it seems to try to run rather faster than that, then the steppers miss a step and it locks up.
(the mill, that is, not the program)
Once the speed drops down slow enough in deceleration that the steppers can deal it runs OK again.
The maximum I've set in the .ini does seem to be OK using the "Run Test" option in the stepconf wizard.
if you turn on the velocity display, what does it show when it's going too fast?
do you know maxvelocity is in units per second? (not inches or mm per minute.)
Yes, and it's set to 12. 12mm/s is fine on the hardware.
The velocity display while it's going too fast is a bit hard to read (since it's still accelerating) but it gets above 820 that I've seen - and that's above the 12mm/s limit.
it will go over 720 if you are moving diagonally
12mm/s is an axis limit. If you're moving X and Y at a 45 degree angle, you could get up to about 1000 mm/min velocity (12 * 60 * sqrt(2))
Yes, I know. Two minutes and I'll see what I can get it to peak at on a one-axis G0.
if it still seems wrong, you could put your ini file on http://pastebin.ca
so we can see it
bbl, work calls
OK, this is a bit confusing. The velocity display on a single axis tops out at 720, which *should* be OK, right on 12mm/s. But it's clearly not moving at the same speed as in the stepconf wizard's test set to 12mm/s.
(By a fair margin - sounds, going by the buzzing noises from the motors, about twice as fast?)
it may be that in the stepconf test, it never gets up to speed because of a low acceleration?
Unfortunately I also just managed to bugger up one axis when it ran into the endstops.
or, maybe stepconf does it wrong
Yeah, sod's law. I'll fix it. :)
Acceleration's about 15ms^-2, and I was using the left/right buttons not the rattle-back-and-forth bit so it seemed OK.
I'm going with stepconf's doing it wrong (in some way or other) and I should really just turn down the max_velocity for now. :)
yeah, it sounds like 12 is too fast, so just lower it. I agree it might be a stepconf problem.
what version is this?
Not sure on the version numbers, it's the version on the Ubuntu 8.04 LTS CD image on linuxcnc.org
help/about inside EMC
run your updates and you'll get 2.2.7
I would, but the machine with the mill attached isn't on the network. :)
It's on my todo list, just after unjamming the X-axis. ;)
network is the easiest way to update (by far) but you can do it without. There is some information on the wiki about that.
[16:17:17] <cradek> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Released
^ you can see there are quite a few stepconf fixes
I'll have a look.
archivist: I'm sure we're not as rare as all that. :)
Gah, got to strip the couplers off the X-axis entirely to fix.
* MH^WrongNetwork goes to fiddle.
i have a tool whose center height is floating
on this lathe
it is quite possibly the most annoying thing i have tried to deal with
the turrent isn't indexing repeatably
worn locking pin
our old Herbert is loose but still manages centre drills
archivist: well, they are stuff enough to cut off center too

is there some law that says every forum must aruge about a plane on a treadmill at least once
but it's like Moore's law - not really a regulation, just a description of the facts

I know there is a municipality here in WI that is installing hydrogen generators on their vehicles.. The news clip said - 40% better fuel economy.
jeeze - http://www.beloitdailynews.com/articles/2008/11/19/news/local_news/news01.txt
11.1 miles per gallon to 21. 9
skunkworks_: Hydrogen fuel enhancement from electrolysis of water where the required electricity is supplied by the engine’s alternator or 12/24-volt electrical system can produce fuel efficiency improvements on an older diesel truck in the order of 4% and similar modest reductions in emissions, and is currently in use in Canada. ; However recent tests by consumer watch groups have also shown negative results.  
[20:29:24] <jepler> http://en.wikipedia.org/wiki/Hydrogen_fuel_enhancement
100% improvement? probabl ynot.
some interesting things in Talk: http://en.wikipedia.org/wiki/Talk:Hydrogen_fuel_enhancement
I always see "if you make some adjustment to the engine/mixture/gas and the mileage goes up, IT'S PERPETUAL MOTION!!!1!"
but ... that's not true
I remember some hydrogen hype from the early 1980's
Yes - I think it is a bunch of bull. (just so you know where I am coming from.)
lower temperature normally means lower efficiency so its BS in the main article reason Diesel is more efficient is the temperature and expansion
diesel egt's are lower though - is that just because more energy is extracted during the power stroke?
that is cool.
higher compression ratio = more adiabatic expansion
you can make liquid nitrogen if you get the ratio high enough
there was actually a doodad on ebay the other day that did exactly that, i believe?
looked like a tank mounted compressor but made liquid nitrogen?
they had one in the chemistry department, my dad (chemistry professor) called it "the fart machine"
I dont fart nitrogen
that may imply something else :)
you do know it is big oil suppressing all the high efficiency stuff.. ;)
is there a book somewhere that has all the math for combustion engines
A guy here at work (he also tried to make a perpetual motion machine) make one of the electrolisizer(sp) for his car. He came back the next day and said 'it doesn't make much hydrogen'
the same company that sells the 'power supplies' also sell magic O2 recalibrators. (so I would guess it leans your engine out also)
I have a few books at home from the Lucas technical library when the Birmingham factory shut and although they did early fuel injection and other work I dont remember any hydrogen snake oil in the books

oh boy. http://peswiki.com/index.php/Main_Page
Is it possible to build a device in which the forward motion turns a wheel that turns a propeller which provides enough wind propulsion to accelerate the device forward faster than the air around it? You would think not,
yeah that's pretty much right - I would think not
cool, they are exploiting the zero-point field
people are idiots
skunkworks: it doesnt *take* all kinds, we just *have* all kinds ;-)
I like the treadmill one.. Does anyone wonder how much power the treadmill is taking? ;)
hehe another idiot with magnets, we have a local here must get his name to see if any link
see peswiki link above
good night all
I found a vhs tape of pictures from the 50's of my family in my dads things... how can I convert that to dvd to share with my family
just go to a local photographic supplier they will know someone with the right gear
becoming a more regular service, some video capure cards can deal with SVHS in but quality may not be as good (needs a timebase corrector)
I know my older sister and mom would like to see them... I'll check what is here in the back woods
gotta go talk to you later
BigJohnT, do you have the original 50's pics
some people need training to leave the client connected
