good night all
* alex_joni heads to bed
the live cd on linuxcnc.org is now 2.1.0 isn't it?
work on the lathe? ;)
nope, not yet
you know how it goes
the house needs some work and I'm busy putting that off
I never have that problem
* Skullworks is an expert at rescheduling work indefinately.
we got 13 inches of snow last night - now we are going to get another 10 or so tonight.
near lacrosse WI
where are you located?
we got snow last night also - but it was like .130"
I bet you get a bit more snow than we do ;)
This is kinda a natural hole for snow
Denver ( 70 miles north ), Pueblo ( 45 miles south) both get it much worse than we do.
that could be good - i kinda like it.. (skiier)
but one of these freak 10yr or 50 yr storms might dump 4 feet.
never tried skiing
have enough other expensive life threatening hobbies.
that - I think - is my only one.
everyone needs a few pet vises
or is it vices
vices are what gets you in trouble, vises holds things
wilton bench vise, Kurt mill vise
I have Wilton C-clamps, for those jury rigged jobs.
I started counting vises one day, I think I stopped at 10 or so
I bet you have more than you think you do too
I have two bench vises (3.5" wilton, and a 5" one in the garage)
two drill press vises (one tilt, one plain, from an auction)
well, thats true - but my micro 20mm vises , I could hold a dozen in one hand
a little toolmakers vise
an old 6" mill vise
a 4" kurt
one of those little suction cup vises you use for electronics work
I'm going to order 3 Chi copy of the Kurt 3" vise.
and a couple more that I can't recall at the moment
Kurt hasn't made them in 30 years since they were a lousy seller
but its a perfect match for my X3
just remembered another one - the workmate for wood working stuff
I'm pulling my hair out trying to find GOOD Ballscres I can trust at a price less than I paid for the whole machine.
you want ground ones, not rolled?
either the precision rolled at spec'd error of .001"/ft or less - or cheap ground.
EMC can do screw error comp
found some ground - but they didn't harden the srews
they were soft stainless
Going to contact hiwin and see what they can offer
Rockford does not do ground, and has had some serious quality issues on the ballnuts.
Nook is a possiblity
does the screw error comp work all the time?
what do you mean?
as in jogging
once you are homed it works
so you build a lookup table?
(it "works" even before that, but if you are at one end of the screw, and EMC thinks you are at the other, the comp won't be right
or is it a set correction value
no, a table
it also incorporates backlash comp
the table has three columns
where you are, the correction to apply going forward, and the correction to apply going backwards
up to 256 lines IIRC
if you have no backlash, you make the forward and reverse corrections the same
how is the backash working in the current release - I heard before it was best to leave that at a zero value
its a little better
the problem is that when you reverse direction, it tries to take up the last using max accel and max velocity
but if the move is also using some accel, the sum of the move accel and the lash accel is higher than maximum
if you have lots of lash to take out that results in following error
I got a scale block to work goofing around - how do I use the comp module?
the comp hal module?
that has nothing to do with screw comp
its a comparator
Skullworks is now known as skullworks-ProfG
there - less confusion
skunkworks: short answer: man comp ;-)
I been reading the CNC conversion soap operas on CNCZone...
* skullworks-ProfG wants to take his money and run...
seems a batch of X axis bearing plates were shipped to customers - they were made backwards
counter bore on the wrong side.
thats just one of many bugs in that one thread
zero specs on the steppers or step controlers - no way to know how to set propper current levels
it just goes on...
makes me cringe
ok loadrt scale works - how do you tell it you want more than 1?
loadrt scale count=342
if you want three hundred and forty two of them
there might be a more sane limit, 8, 16, something like that
thanks - I actually went into the source of comp and got no where :) man comp - I will remember that
wait - exactly which comp are you asking about
(unfortunately "comp" is an over-used name)
there is the python program "comp" which is used to convert something like scale.comp into scale.c which is then compiled into the scale HAL component
there is also the HAL component comp, which is a two input analog comparator (like an LM339)
I was using blocks scale.. but wanted to use the comp version so I would not get the 'blocks are depreciated...
ok, then you just use "loadrt scale"
yep - working
so where did the question about comp come from?
I wanted to scale the velocity from the pluto so It was in rpm.
I guess I was really wondering how to use the comp componants like scale.comp
just like the blocks versions
except that the comp version have man pages
and you load them differnetly
loadrt blocks scale=3 ddt=2
is the same as
loadrt scale count=3
loadrt ddt count=2
I did a loadrt scale=2 and it didn;t works so I figured it was a bit different.
and man scale works ;)
I'm getting there
btw - hal is cool.
Do I need emc installed to use the rs274 and gcode python modules used in gdepth.py?
you mean as opposed to just copying the python code to some handy directory?
the python probably depends on some emc specific libs
bytecolor: install emc or use ". scripts/emc-environment" to set the PYTHONPATH environment variable
either way works
I usually use the emc-environment method
jmkasunich, yes that's what I had in mind. are those modules pure python? or C/Python?
jepler is the authority on that, listen to him, not me
some are written in C
we were poking around gdepth in #cam
the parts written in C are the g-code parser and the interface to opengl
I see. I havent played with emc in a long time
jepler, thanks for the hints
not young anymore?
crotchetyGuy used to be called crotchetyYoungGuy I think
maybe just a case of BA (bad attitude)
ah, yes too long a name :)
* skullworks-ProfG nowdays often feels too old.
I'll be 38 in a couple weeks
good think I decided to switch to ubuntu. I used debian for a couple years.
I'm 43 next month, damn, where did the years go?
45 in june for me
saw the reg users age graph at cnczone
40-49 is the largest group
I'll be in that group shortly...
don't ask how many were 20 or less - was a trace amount.
cool, import gcode in IPython works now
is this the full bug, with the inline macro support in the g code?
I noticed that was expaned quite a bit from last time I played with emc
gdepth keeps segfaulting
test.ngc -> http://pastebin.ca/371199
./gdepth.py -x "-1 1" -y "-1 1" -z "-1 0" -t ".25" test.ngc
it writes the .png, then writes "-1.0 0.0" to stdout, then segfaults
Can EMC work with an Isel Davinci CNC machine?
it would be helpfull if you had a URL or something about that machine
Ok It will take a few minutes I will report back
emc can be made to work with a huge variety of machines
but the amount of work and knowledge needed varies
note: when pasting a URL in an IRC channel, don't use quotes
most clients will let people just click on the link, but quotes can break that and make them paste it manually
it doesn't say what kind of drives the machine has, just "servo"
It accepts Gcode through serial port
that is bad
that means it as some sort of controller built in
to use EMC, you would have to find the connection between their controller and the motor drives, and connect EMC at that point
Yes it has a controller, I can control it with software called PAL (DOS)
(EMC is a controller - you don't want one controller talking to another one, you want the controller (EMC) talking to the drives directly
* skullworks-ProfG has plenty of dikes handy.
BOBCAD(which I severely dislike - crashes always) says that I can control the Isel Davinci as a FANUC machine
Guest717: I converted a Techno router by doing just what jmkasunich says to do- find the connections to the drives
I had to do some major surgery to get at the stepper drives
Guest717: EMC is a controller. You can use their controller, or you can use EMC, you cannot use both
Bobcad Version 6 onwards
it's probably easier to buy gecko drives and bypass all the techno stuff
DanielFalck: what kind of drives do they use?
the URL that Guest717 posted was to a servo machine, not a stepper machine, but I bet its step/dir servos
This sounds all very complicated. Is it not better to just get rid of the Isel? It is a very nice machine though, but I JUST HAVE to move CNC to Linux.
they had parker digipan stepper drives- full step I think
Guest717: there is the Isel MACHINE, and there is the Isel CONTROL
you have to make the distinction between them
What is the best replacement CNC that will work well with EMC?
the machine is fine, it is the control that you replace with EMC
pretty rough, they actually might have been 1/2 step- they used L297- L 6203 (whatever the SGS 3 amp chip is)
Guest717: I don't know what you are talking about
I had to trace the step and direction signals from the L297 chips
Guest717: how old is this machine?
EMC is a CNC controller, it can be used with all kinds of machines
jmkasunich: Simple...I want to solve the problem. If EMC does not support the Isel out of the box I must get rid of it. I therefore ASK id there is a list of CNC machines that will work out of the box with EMC including a servo controller.
out of the box?
Machine is 3 years old
whats that? ;-)
the iron, aluminum, motors, screws, etc, in the Isel - the MACHINE itself, is fine, and in my opinion you'd be nutz to get rid of it
the motor drivers may or may not need replaced
Guest717: are you comfortable at all with doing electronic hacking?
the controller would be replaced by EMC
if not, you might want to use it as is
if you insist on getting rid of it, send it to me ;-)
I dont have time to do brain surgery please understand. It costs my company more to fiddle with surgery than just to buy a new machine. We are a Unix shop, so I star now with EMC and then decide which are the best machine to replace the Isel. As I read from responses, this means that I have to only look at the list of servo controlers supported and then choose a machine that will work with the servo controller. Is that right?
nothing is that simple
it's cool that you work in a Unix shop
a complete cnc system has several parts
control software and PC
optional interface boards to make analog signals, count encoder pulses, etc
We know all that can we stop lecturing?
and the mechanical parts o fthe machine
the only place you can get all those parts already hooked together is Sherline
everybody else does "conversions" - they take the PC and EMC and hook it to drives, motors, etc
Is there something a bit larger than sherline that is as easy in your opinion to configure?
I don't know
what is the application? what are you making?
I'm at the extreme other end of the scale, I go for retrofits
do you know how much the Isel costs?
Mostly 3D aluminium prototype work. Small parts for R&D.
Isel costs about $8,000\
so I imagine replacing it with a new machine of similar capacity would cost similar
what's the company that Ray has been working with? Smithy?
They use EMC to control some larger mill/drills
dunno your hourly rate, but if you could do the retrofit for less than say $4000 in parts and labor, that beats getting a new machine doesn't it?
I guess so, therefore to get someone to do the conversion is going to cost way motre than that in man-hours
[05:04:59] <DanielFalck> https://www.smithy.com/products.php?cid=11
gecko 320s are less than $200 each, thats $600
total material including a PC, drives, and a servo card will be less than $2K
that leaves 20 hours at $100 /hour to hit the $4000 target
DanielFalck: the Isel website didn't have pics, but I think that machine is more of a router than a mill
Guest717: does the work envelope of the Smithy machine meet your needs?
its pretty different from the Isel
my techno is a router and it's very lightweight
I wouldn't use it on aluminum- that would be frustrating
Guest717: sorry about the lecture....
I gotta look into a new tact filter, I think this one is busted
sounds like a desperate situation- having a control that depends on 'BobCad' ....
it blows my mind that people would consider replacing an $8K machine because of the control
we got rid of a couple Traub's that had old Mitsubishi controls on them- none of the shop guys would have been able to handle them
we got them used and brought them back to life - and were surprised at how different they were
so we traded them with another company
traded nicely retrofitted machines for the more with bad controls?
no, they were old.... and we traded them for services on bigger machines
that was a couple years ago
I don't follow
but it doesn't matter really
we work with a company that retrofits very large screw machines- 6 spindle New Britains. They said they could deal with the Traub's. We just wanted to cut our losses and be rid of them
It was interesting
ok, I completely misunderstood your original statement
I just got in on the bar loader hook up of the Traub's
we got rid of a couple Traub's that had old Mitsubishi controls on them- none of the shop guys would have been able to handle them
<DanielFalck> we got them used and brought them back to life - and were surprised at how different they were
I've narrowed down the segfault to _togl.install()
I assumed you meant "we got these old machines with POS mitsu controls that nobody could use, we brought them back to life by replacing the controls with EMC, and we were amazed at how differnt (better) they were with the new controls"
well, they were used and dead. we actually put some work into them to bring the original crappy controls back to life. We were very dissapointed in what they ended up being like.
I wish we could have used EMC at the time.
this was 5 years ago
it would never even occur to me to try to fix the old controls ;-)
yea. That's not my first impulse either - with EMC around.
its amazing how one sentence can have totally differnet meanings to two people
sorry. I can really twist things around sometimes : )
that wasn't the problem
I just made some incorrect assumptions
jmkasunich: I came up with a spiral boring routine, kind of like Jon Elson's routine in Apt today.
bytecolor, crotchetyGuy, tomp, fenn, and myself are really having fun with apt.
well, maybe fenn will need some indoctrinating....
I'm having fun at the other end of the code - doing 5i20 stuff
I'm really amazed with how fast you guys are coming up with hardware drivers
and new ways to use emc
hrm, I think I had the wrong ver of tk and tcl installed
a motion control board
DanielFalck, did you ever try gdepth.py?
bytecolor: I just looked at your pastebin- get rid of the %
ok, wasn't sure about that
not sure if it will barf, but try it
gotta familiarize myself with the ngc format
well _alrighty_ gdepth is working now :)
*very* cool little app
oh yea, I fired it up
I fscked up and installed tk8.0-dev instead of 8.4
wonder if that's CSG, or voxels or what
have to pick jepler's brain sometime
being sick sucks
anyone ever mention doing the mouse rotations in AXIS like modern CAD/CAM? Where the axis of rotation is perpendicular to the mouse vector (ala Solidworks, Pro/E, FeatureCAM, etc...)
guess it's whatever you get used to
was just playin with this,works really cool
alex_joni: wiki is down again
the icing on the cake would be if after you hit touch off ,and entered the nunber value
if the enter key would work,you have to go back to keyboard to enter value
jlmjvm: hmm.. enter should probably work even from the touchpad
or it's an ISP thing...
it replies to ping
it's on dreamhost too ?
only the enter on main keyboard works
I'd like the g92, g54 etc. offsets to be viewable in a pyvcp notebook tab. one way of doing that is to run an endless loop that exports some of the values from the emc status structure to HAL pins
awallin: wiki is on dreamhost too
awallin: do you know some python?
is it possible to generate a keyboard event?
hmm, think I figured that out (raise "<Enter>")
jlmjvm: yeah, doesn't work yet for touch_off.. still trying :D
if that would work you could do a whole setup from the keypad
jlmjvm: the fix is a oneline (by modifying AXIS)
not sure how to do it from .axisrc
I need to access an object that only gets created once you press Touch-Off
jlmjvm: I'm afraid here is where my python knowledge ends
* alex_joni pings jepler
I'm not very good at python... although I hacked together the first pyvcp version
how do you get to the tool and fixture offsets in axis,i cant find them
I don't think you can... if you switch between machine position and relative position, you'll notice the difference
but I don't think there's a window or anything where they are displayed
they're set by G-code (MDI or program)
you can visualize them with pyvcp :P
they are exported as hal pins from iocontrol.
the current offset, or all of them ?
er.. not the offsets
tool number and size
sorry, didn't read the whole line
there needs to be a way to get to them
you set them with G92 or G10 or something?
should be able to open a box and have your g54-59 offsets,and 1 for tool lengths
i dont think g92 set a fixture offset
yes, tooltable and offset helper programs would be nice
g92 is probably called something else
if they're coded smartly they could perphaps work both standalone, and in a pyvcp panel
that would be so cool
but the current tool table isn't in the most easiest to parse format... (XML would be easy)
the axis gui looks great
a tool-table helper application which would read/write to an XML file would not be hard to do, a basic program would be a couple of hours to do for someone like me and probably 30min for someone good at python/tkinter
awallin: wanna volunteer?
awallin: wiki is working again
alex_joni: I did try parsing the current tooltable file with python, it worked somehow but not that great. I'm not really interested in text file parsing, so if I would write something in python it would probably read and write from an xml file
21 inches so far here.
we get it in cm over here ;)
we dont even get that here
awallin: you can parse whitespace separated strings very easily with string.split
awallin: I think the tool table is probably the easiest emc file to parse :-)
do you know enough python to help jlmjvm ?
what's the question?
he has an issue with the Touch Off popup
the Numpad Enter doesn't work.. only the regular one
cradek: sure, the number values are easy to extract, it's all the headings, blank lines, and comments that are problematic
awallin: if you're editing it in a gui, I think you can throw that stuff away
because the headings etc. will be in the gui now
cradek: I think a bind for "<KP_Enter>" would be enough
but I couldn't figure out how to do that from .axisrc
alex_joni: just fix it in cvs - no reason for that not to work
cradek: I managed to check for KP_Enter and raise a normal one, but it only works for the main Window
ok, I'll do that
anyone else having problems with bounced e-mail on the list? SF keeps dropping me..
but I thought there might be another way to do it from .axisrc
dave_1: your ISP bounces a lot of messages sent to you
dave_1: the problem is not SF
dave_1: hi dave

t.bind("<Return>", lambda event: (self.ok.flash(), self.ok.invoke()))

OK, this is what I needed to know
dave_1: one other charter user gets this too - you will have to get it fixed on their end
jepler: yeah, but only in a while.. you can do it now if you like
jepler: I take it there's no way to change that from .axisrc ?
(except redefining the whole touch_off class)?
yes, that would be the way
t.bind("<KP_Enter>", raise "<Enter>") <- how's that?
that's not even english^Wpython

are you talking bout the ubuntu cd,or just an axis download/
an emc2 release
when we make an updated package available, your update manager will offer to download it,just like for any of the other updates

got a few questions if anyones about
wow I think I finally got my mouse touchpad to behave in ubuntu
only borked the xorg.conf once ;)
col: ask, and if someone knows the answer you'll get it.
much better - not click where I don't want to.
hmm - what do you guys use to stream audio from the web?
cat < wget
I use xmms for music
thanks - now I only have to figure out why I need to open the administration/network before I can get hooked to the network :)
I use amarok for all kinds of music. mp3/ogg/streaming
alex_joni: question. Now that I am running 2.1.0 on here plus head... HOw do I re-disable it? seems to be doing it now. I thought you had changed it some how so it was a bit easier or do I still need to do what we did before http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?FixingDapperSMIIssues
sorry - in regards to smi
skunkworks: disable smi you mean?
or reenable it?
seems to have been re-enabled when I updated to 2.1.0
getting rtlatency every 90 seconds or so
I still have the rtai_smi.ko file on my desktop - but I thought there was a few files that you had changed.
jepler: thanks realised its a stupid question that i need to find more info on to be of any use
skunkworks: I changed something inside emc2.1.0
so you can loadrt rtai_smi in your hal file
but you still need the modified rtai_smi.ko file in /usr/realtime...
I didn't upgrade the RTAI package yet
I can probably handle that ;)
if it's the same machine, then you only need the loadrt rtai_smi in your hal file
but the only issue with that is - how would I use the RTAI Latency test to test it?
sudo insmod rtai_smi
then latency test
skunkworks: can you upload the binary to the wiki?
alex_joni: that worked - thanks
skunkworks: cool, can you upload it to the wiki?
how would I do that?
[20:02:39] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?action=upload
alex_joni: should be there - how do you see a list of the files?

This is so much nicer now that the mouse doesn't click everywhere ;)
cool I just arranged to buy 25 L298n's @ $3/ea. - I'm going to make some majic smoke...
what are you gonna do with that many L298's
good morning everybody
(its gotta be morning somewhere....)
kinda late for good morning
it always is..
I got 9 hours of sleep last night!
that's enough for the whole week I bet
or was it for last week?
it was a futile attempt to catch up
I gotta stop staying up so late
but unfortunately thats when I get the most work done
didn't see any complaints about the motion change last night
I wonder how many people use freqgen?
(most should be using stepgen)
I think a few people use freqgen (but for something else, like chargepump)
I was only using freqgen until you got the pwmgen working.
man freqgen mentions (in the bugs section) a few quirks that I'd like to fix for 2.2 - inconsistencies between freqgen and stepgen
bet that's ok to do then
now that I'm working on the 5i20, I was reminded of the mismatch
because at least for now, the 5i20 works like freqgen, with an external PID
might put the same pretuned loop stuff from stepgen in the driver, but it has to be optional
jmkasunich: have you run your hardware yet with the mesa step firmware?
yeah, last night I had a motor going at 100K steps/sec
* skunkworks has never had hardware step generation
what does that relate to rpm?
assuming 10X microstepping
100000 / 400 * 60 = 15000 RPM
1.8 deg step as example..
200 steps per rev..
for the motor I have as paperweight
it smells fried
that's the most common
I used 400 for halfstepping :)
alex_joni: what are you gonna do with that many L298's - Try to make some small PWM servo amps to run off the Pluto-p
how many amps?
or you plan on frying your way through? :D
about 7A for the X/Y and about 12 on Z
those are surge - G00 reversal
dual H-bridge chip without internal freewheel diodes
I thought they where only 2 amp
7A is a bit much for the L298
or you what to parallel them?
rated 2A DC cont for each bridge - going to have to gang them up
why not use MOSFET's ?
Seen a stepper driver which ganged 3
skullworks-ProfG: I have been playing with the pluto off and on. I really like it.
because the L298n is cheap and MOSFET is way beyond my education level
I been out of Electronics since the late 70's
so I'm trying to relearn - but designing a bootstrap, and having a fool proof circuit for shoot thru... thats beyond my current skill
skullworks-ProfG: have you looked at the integrated IGBT packages where you only need to provide logic signals ?
maybe later - or if I come upon a proven mosfet design.
I have some Pittman 14203's for the X/Y and the BIG 14 series for the zZ
yeah - that looks great
but I have not seen anything other than the pic
that has a bootstrap circuit on it - lots and lots of help from jmkasunich

skunkworks: about RPM: I'm running 200 step/rev motors, and 10x microstepping, so 2000 steps/rev
100K steps/sec = 50 revs/sec = 3000 RPM
I was right ;)
how much where you getting software?
skunkworks: looks really nice
Is 100K/sec he gecko limit?
350 kHz maximum Step pulse frequency
for the 203V
anonimasu: thanks - jmkasunich did the board so it is his art :)
is ovlmax 25747 bad?
max latency of 26us?
skullworks-ProfG: 100K/sec is pretty close to my motor's limit
the driver as it exists now doesn't do smooth accel
if I change from 100K to 101K steps/sec, it does it instantly
and that made the motor stall
so needs a ramp profile
right - the driver will do that once I finish it
* skullworks-ProfG goes running thru the house booting all the systems.
I need to collect a bunch of files on the USB drive before I head over to the shop.
Someday I need to hammer out the Wake on LAN function...
I like the quote on bash.org where the dude can ping a certain machine ... but not physically located it in his house
it is pretty easy. bunch of utilities.
We turn on our multimedia pc that way.
I'm toying with a multi-media box - KnoppMyth
* skunkworks hasn't played with linux for a multimedia pc.
I pooched good - ext2 dose not like unexpected poweroff while writing streaming vid.
clean format/install will fix all :)
why not ext3?
The way the Knoppix/Myth install works its not an option
but if I was doing a custom build I would use jfs I think
deleting large files is the big issue
you can always convert an ext2 to ext3
seems everything grinds to a halt during a delete
jfs can wipe better than 1gb/sec
so most times the buffers/cache won't starve/overflow
Its not a seriuos project for now, I have no time to play with it or watch captured content.
As is I have to figure out where I'm going to shoehorn in the New IH mill I ordered.
international harvester? ;)
skullworks-ProfG: didn't they go out of business?
Since the deal on the new property fell thru - I'll have to stick this in the kitchen.
They closed in Dec - but there was a ownership buyout in progress
there are open again
now based in CT
and the new guy is even more hardcore
skunkworks: still got a roof over your head?
We close on the new house on march 7th and on the house we are selling on april 4. so far so good.
He told the mill mfg they must buy a new grinder to finish the ways before he would order another lot.
that has been done
Anyway the next container load should hit U.S. Port about April 1
skunkworks: I was wrong before
loadrt rtai_smi won't work
you need to add rtai_smi to rtapi.conf
like we did before?
just edit /etc/emc2/rtapi.conf
hmm looks like it is already there MODPATH_rtai_hal=/usr/realtime-$(uname -r)/modules/rtai_hal.ko
MODPATH_rtai_hal=/usr/realtime-$(uname -r)/modules/rtai_smi.ko < I need to add this?
skunkworks: you're looking at /etc/emc2/rtapi.conf ?
I don't see that by default there
I was wrong
and to the MODULES="
I'm off to bed
good night all
skullworks-ProfG is now known as skullworks-away
yo ho ho and a bottle of tequilia!
