How would the command m101 get to see all of the other stuff on the command line. (Or to use gcode jargon: in the block)?
more importantly, how does it cause canonical calls to be made
hmm m-codes only have 2 arguments
That's a kludge. At least, my kludge :-) is complete. In the sense that you should be able to implement any canned cycle.
one advantage of not using custom g-codes is that axis will render them properly in the preview
Some of the threading canned cycles have a lot of parameters. Hey. I hadn't even thought of that.
-- fenn's comment.
that's an understatement :-/
Do we currently have a file that is read (for interpretation) at startup of the interpreter? (Before any user file is read.)
So, I would have to add that. It would be supplied (in theory) by the integrator.
And it would be the only place where owords with negative numbers would be permitted.
So, g82.1 would be implemented in a subroutine named o-821. Of course, with named owords, I could just use oG82.1.
I'm bothered by this in a fundamental way. We already have our own gcode (ngc) that's incompatible with gcode done by other manufacturers. you're proposing that (potentially) all our users will have a gcode language that are incompatible with each other.
They already do. fanuc implements something different than Haas, different than ... etc. It depends on what canned cycles you've paid for.
no, that's not what I said. This makes EMC2 user "A" and EMC2 user "B" unable to share their programs.
I don't care about Fanuc users (although a program written with G0/1/2/3 will probably work fine)
Well, as long as they installed the same canned cycles, they could.
they can't install my G99 and your G99, so they can run my programs and yours.
In our case, most EMC users are their own integrators. (Is that true? -- are there a bunch of Sherline users who depend on Sherline to integrate for them.)
yes I think we have a LOT of sherline users
and at least a few other manufacturers
Well, I assume that we will try to implement industry 'standard' canned cycles. If you install your own, you might be out of luck.
who is we?
Assignment of canned cycle number should be strictly controlled (by the board of directors).
either you give integrators control, or you don't - I think I am not following you
dammit I hope it doesn't seem like I just like to argue
Presumably, the board would say: g82.1 should be implemented according to the way Haas (or whatever) does it. You can never really control an integrator. But I assume that some integrator might need a canned cycle g82.1 and then implement it to install. It is to the integrators advantage to be part of the community, too.
Nah. If people don't question things, we wind up writing things twice. -- gee: like my recent parameter stuff. (but that will be easy to fix.)
if the board/community thinks we should have g82.1 today we'd just stick it in the interpreter
I think it would be a lot harder to put there that to do it using a gcode subroutine. Also, not many people can read the C code to understand how the cycle works (or even find out where it is implemented).
* fenn either
i can read C, but not C written by a program
Which C is written by a program?
most of the interpreter
No it isn't -- at least it doesn't look that way to me.
some of it is maybe a bit strange, but it's certainly written by a human I think
To the degree that programmers are human. Which is arguable.
well, its been a while, i might be thinking of something else
NML, maybe? I haven't looked at it at all.
i just crack up laughing every time i look at that
interp is really long for what it does though
I've never considered that.
rs274ngc is a really rotten standard, though. Very limited line length, squishing out white space, conversion to lower case. All of that is a crock in a modern environment. But, I suppose it might have been necessary to keep old programs punched on paper tape working.
In the name of compatibility, we are stuck with junk. As we add new features, they have the same junk.
yep that's why i think its better to use a different language that outputs raw g-code
or acts directly on the state variable
Just don't try to read the generated g-code. But -whoops- that's all that axis shows you.
well.. lets say we used a source level debugger in the edit window
So... the right way might be to use a different language.
what would you want it to highlight if you clicked on a line in the preview rendering?
Say, python (to name someone else's favorite), for flow control with embedded g-code stuff.
the final API call? the last function called? a stack trace?
A stack trace would do the job, nicely.
ok i think thats a reasonable interface
will look at various python modules to see if any do what we want already
But what would be the underlying cannonical interface -- the same old gcode?
gcode is above the canonical interface
Yes, but it is pretty close.
The issues: ...
How do you machine lines, arcs, etc
How do you specify coordinates, origins, offsets
How do you specify cutter compensation
Would we just use python for control structs? Parameters? Computations? etc?
which would be easier to interface to?
We could, I think. But that would have been a lot harder to integrate into the interpreter than what I did.
gcode or canonical?
the canonical function calls are already pretty well specified arent they?
gcode might be easier. I could imagine kludging an interface to the interp so that it was fed a line at a time from some new interpreter.
Yes. It could be done by using existing canon.
i just think its a bad idea to layer cruft needlessly
It is well defined -- with a separate doc, I think, and a machine model that is well specified.
I agree that adding layers is bad.
i think g-code is useful for what it does, but we'd be fighting it if used as an API
But, what would be embedded in the python. It would be easy to say:
g1 x#pythonParam x#pythonThing
in the middle of a python program. Use a special character or word or something to tell the interpreter that this is an output line (perhaps its already there).
that would call the existing g-code interp
What would be embedded (and how) if we used 'canon' directly?
you'd use SWIG or something to call the C functions directly from python
The user (today a gcode programmer) would have to learn some python AND learn canon.
the python layer would be for writing wizards, right?
Well, there are two issues, then:
1 -- what does the user write (let's say gcode inside of python)
2 -- how is it implemented (kludge the interp or have python library call canon)
but it should easily interpret standard gcode so you can run any g-code program into the python shell
It could be. But average users (me) could use the python layer directly.
ok i see two scenarios
I think that might be the wrong model. Have Axis read and display the python directly.
one, is an end user writing a specific part program
the other is a developer writing a wizard for many different possible applications
the end user should be able to write G1X2 etc
but also be able to call python functions that have been provided already
I'm a user. Suppose I wanted to generate a flowsnake. How would I do that?
you'd write a python function
is that too much to ask?
OK. I can write a python fn as well as a kludged gcode subroutine.
Do you python? Could you translate my flowsnake program into your proposed language?
* fenn looks
As in... you're turn to write a proposal for the wiki. :-)
i have to understand the algorithm first
I just googled flowsnake and found a java implementation.
oh i thought you wrote it originally
Nope. flowsnakes have been around for a long time.
Sorry that wasn't clear.
* fenn is converting flowsnake.ngc to flowsnake.py
bah.. python and its stupid commas
[01:13:28] <fenn> http://pastebin.ca/298550
save to flowsnake.py and open with axis
* fenn looks around for an old mailing list post
I believe you. Suppose you wanted to build a new interpreter that took this directly. Clearly, the print lines are NOT nice.
that's just a first pass to get it into valid python syntax
instead of a new interpreter you could make a python gcode object with rapid(x,y.z) feed(x,y,z) etc
if you don't like print "g0 x%f y%f" etc
You would want them to say something like:
foobargag g1 f10 xendX yendY
Where foobargag denoted something special to inform the interpreter that this was going to be interpreted like good old fashioned gcode. And endX endY caused the current values of those python things to be embedded. We gould do that because the spaces WOULD be significant in the new language.
you could snork some of the code from print for that
Well, I might want to have spaces after the x and y.
then you get all the fancy format features
ferinstance gcode "X%f Y%f Z%f" (x,y,z)
or block quotes
gcode """ <50 pages of data> """
and it would be routed to the old interp
or you could use print :-)
but feed(x,y,z) would call the canon call
LINEAR_MOVE or whatever
The problem with print is that you have the nasty quotes and commas.
are you making this for programmers or machinists?
would you rather something like
gcode "x" x "Y" y "Z" z
gcode "x", x, "y", y, "Z", z
But since we have the source to python, we can make it do what we want. And since it is line oriented we could look for the word gcode at the beginning of a line. I'd like:
gcode g1 f10 x endX y endY
gcode g1 x10 y20
gcode g1 f10 x endX y endY poses some problems
The problem might be that you would have to be careful that there was no variable named x. So, maybe you want want to require:
gcode g1 f10 x#endX y#endY
how do you recognize endX as a variable without all the ugly tricks you have to use in the rs274 interp?
That would be reasonable to read and write. If you did not want to use any python, you could still read and write this.
spaces WOULD be significant.
ok.. i dont know how to go about changing the way python interprets its source
An issue is whether to support X[1+2]. I'd say NO.
We would have to write our own language that looked like python with a little added stuff. I haven't looked at the source of a python interpreter, but it would probably be pretty easy to do something special with lines starting with "gcode".
i'd rather not mess with the python interp
unless its easy to add a module
I know. Isn't a module just a subroutine? If so, then you have the issue of how do you make that line look nice for a 'normal' gcode writer.
I suspect that there is no neat way. (without a mod to the interpreter)
is it really worth it though?
you'd still have to add gcode to the beginning of every line
Yes. (Aren't you the one who wrote:
bah.. python and its stupid commas
heh actually i was complaining about python in general
Or something else that couldn't be on the beginning of a normal python line. Maybe just a colon.
because arguments to function calls are separated by commas
but lerman if we use print it's all done already
<insert gcode here>
Yes. But it looks' like crap. Particularly if you want to have python parameters inside the gcode line.
use %f then
konqueror crashed in the middle of my wiki entry
:g1 f10 x#endX y#endY
print"g1 f10 x", endX, "y", endY
(assuming a colon as the first character of a python line is illegal)
Which do you think is easier to read/write? Was I missing a quote or a comma?
the second one
* fenn thinks this would be easy in lisp...
does python have reader macros?
because it's python, and I know python - or I can learn it by using the tutorial or getting a book
Let me change the question. Which would be easier for someone who presently writes gcode to use?
that person would grumble at either one, and would continue to write gcode
(A typical debating technique. If you don't like the answer to a question, change the question.)
I think we (you?) should admit that we have gcoders and programmers, and not force them to use the same langauge
fenn keeps saying that other languages are already fine, you say they're confusing to gcoders -- you're both probably right
Well, I'd like to offer more to the gcoder -- in an incremental path.
that's certainly a challenging task
Without requiring that they have all of it at once.
(especially when you want several increments)
Hello, Chris, and everybody else, and a happy new year!
python is a lot easier (for me) to read than in might be to write. The language seems easy -- the libraries are hard.
maybe i'm spoiled, but i think python is really easy to learn, at least at a basic level
...and the best to all of you.
I think gcoders write simple programs, or make the jump to CAM
thanks jon, same to you
it's not quite that time here yet

For the Europeans, they are already there!
errr... geez make that "HAPPY NEW YEAR"
Hey jone - happy new year
the killian's irish red must be catching up
I'm trying to get homing to work on my Bridgeport, with current EMC2 and the hal_ppmc.c driver. I made sure I'm getting the index signal through to the ppmc.0.encoder.00.index pin, and it responds correctly to the home switch, but then just keeps searching. I'm pretty sure the home_latch_vel is slow enough that it is not missing the pulse.
elson: Are you running head? I think there was issues that where fixed in head but I don't exactly remember.. or was that just for the motech card?
cradek would know ;)
It seems maybe there are some settings of the homing params that don't work right. There was a message from John Kasunich about it, but I searched and can't find it. Yes, I'm running with a head version from about 3 days ago.
have you hooked axis.N.index-enable to ppmc.whatever?
axis.N.index-enable <=> ppmc.N.encoder.NN.index-enable
No, axis.n.index-enable enables the resetting of the hardware counter by the index pulse. Not all encoder counters can handle this. I have updated USC and UPC for this, for threading support. I haven't done the PPMC yet. So, it can latch the count, or it can tell you it sees the index signal, that's all. Does EMC2 now only support index by zeroing the counter on the index pulse?
I think this is the connection you need
I don't know that answer for sure
My current PPMC hardware does not support clearing the counter from the index pulse. I guess I can revise the FPGA config.
I think that's the canonical way of doing it now - I'm not sure whether or not there are other ways too.
There is an axis.n.index signal that is an INPUT. If it is not for recognizing index, what is it for?
I think that's how mdynac has his motenc set up (and we recently fixed motenc to support it)
wait, what version are you using?
I'm looking at 2.1/head
you may be right about how homing to index works in 2.0 (I'm actually not sure it works at all)
OK, well, I have wanted to add the threading support to the PPMC to align it with the other boards. I got my update from emc2-head (is that right, or is it only emc2-head on my system?)
I don't understand - are you using the packages or did you build from cvs?
[02:00:57] <ejholmgren> http://video.google.com/videoplay?docid=727346500427703770&q=lathe
mmm machine tool porn
I built from cvs. I think this is the most recent checkout command I used : cvs -z5 -d:ext:email@example.com:/cvs co -d emc2-head emc2
scary how it drills toward that end mill
elson: ok, I don't see axis.N.index then - are you sure?
i like how it holds the piece for parting off
halcmd: show pin axis.0.*index*
05 bit I/O FALSE axis.0.index-enable
fenn: I think it can also machine from both ends of the stock also. (passing it to the other chuck)
fenn: you saw the hex turning lathe right? http://www.youtube.com/watch?v=oGq-9NNmr3o
Chris, you are right, I was misremembering what I saw.
I'm pretty sure it will work right if you can update the firmware like the others
I'm being dragged off to dinner. But, if there is no longer an input to axis (or whatever) to sense the index signal, then it is clear I MUST reset the counter. Needs to be done, anyway!
have a nice dinner
Thanks, home made pizza!
greetings.. from 2007 :)
hi alex from the future!
the world is still here, and just as mad
cradek: yes, do you understand how that makes flat surfaces in one pass?
alex_joni: I guess that's good to hear
fenn: my guess is 'simple geometry' but I haven't figured it out
its definitely an idea worth worrying about
cradek: the main spindle is way slower than the other one
no i think they are synchronized like gears in mesh
and changing the phase relationship changes the angle of the rounded shape that gets cut out
fenn: but it's not a rounded shape that comes out
and somehow you can use that + a linear movement to make a flat shape
like a hexagon
if you look at that video again, you'll see that the cutting tool has a far greater velocity
they are synced
but something like 1:2 or higher
also note they're counter-rotating
the cutting tool has a larger diameter
so I guess that's the ratio
if the main spindle (the stock) would be fixed, then the cutting tool would make an arc.. right?
i cant really tell how fast they are moving relative.. there's aliasing on the chuck jaws which makes it look like its going backward
but also on the polygon cutter
also, if they would turnwith the same speed, then you would get no cutting
not true if they're counter-rotating
well.. at least you cut in the same spot
more polygon cutting http://www.youtube.com/watch?v=SlLyXIcv6b0

[06:29:59] <fenn> http://www.remsales.com/pages_blocks_v3_exp/images/links/POLYGON_MILLING_[Read-Only].pdf
i think you could do square or hex in two or three passes with only one cutter
would make setting up easier since you dont have to align all the cutters precisely
fenn: after 3 martinis, the gear cutting video is really cool! happy new year ( i love russian vodka http://russianvodka.com/russian_vodkas/moskovskaya_vodka.htm)
I re-commend the 'Martini Room, Elgin Illinois', great entry show: a girl steps out of a cab, drops keys. bends over, wind blows dress over head... too good to be true! honest it happened as i walked in! I am damn lucky!)
happy new year you old foggies. :D
that polygon milling stuff is cool :)
swp showed me something last week
it's pretty cool when both things spin in timed sync... to creat X # of flats.
polygon milling whaaaat???
happy new year
awallin is now known as etla
I did a bit of the python-vcp thing yesterday
now I'm playing around with layout for the widgets
I'm reading an xml file with the widget definitions, looks a bit like a .vcp file
one day you'll want to make that proper XML
proper meaning ?
that can be validated
e.g. write a schema for it :)
that needs a DTD ?
do you know of any good python intros ?
try this: http://docs.python.org/tut/tut.html
it might be elementary for you though...
elementary is what I'm after right now:=

nm, found something
I'll take you up on that offer when I'll be back home
internet right now is damn slow
is 2.5 justified?
or should I get 2.4?
no idea, I use what comes with emc2/ubuntu6.06

good morning and merry christmas

I get them confused :-P
etla: holy cow that's a lot of progress for a little more than a day!
jepler: yeah, it wasn't too bad, I did do some python tutorials before...
jepler, etla : I'm more and more impressed how quickly you can do things in python
yep, sometimes it's scary effective...
but it's also easy to write quite cryptic code
happy new year
[15:10:21] <jepler> http://emergent.unpy.net/index.cgi-files/sandbox/axis+pyvcp.png
cool! that was similar to what I imagined could be done !
a bit of polishing, but looks nice already
I modified the vcpparse module just a little bit, then put this in ~/.axisrc:
f = Tkinter.Frame(root_window)
f.grid(row=0, column=4, rowspan=6)
basically I changed vcpparse so that it doesn't do anything when it is imported, and so that it can accept an argument for the Tk frame and hal component to use
so maybe my code wasn't all rubbish then...
[15:15:15] <jepler> http://pastebin.ca/299178
maybe I'll try that
hmm.. I don't have an existing -axisrc
oh, and the .xml file went in the machine configuration directory
Can not find -sec HAL -var HALUI -num 1
Stopping realtime threads
and where does vcpparse.py and pyvcp.py go ?
yes! it works!
the cursor flashes whenever I point at a widget
etla: in axis, I have some special logic to only .set() a Tkinter variable when the new value differs from the old one
etla: otherwise, tk may redraw the widget(s) affected by the new value
I'm not sure why that would make the pointer flicker, but I wonder if it could be because Tk is continually redrawing...
jepler: right, the update() function for each widget should probably not do anything if the value does not change
now it's in the wiki
[15:33:30] <etla> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PyVCP
etla: what do you intend to control with it ?
jepler: this way, you can just say 'do it with pyVCP' to people who beg for new AXIS features
etla: I hope you'll put a GPL license block and check it in soon
alex: I think spindle control, viewing part and tool offsets, servo command(load) etc.
jepler: that's encouraging ! where do I get the standard GPL header ?
hm there are files without the header in lib/python
maybe just copy/paste from some other emc file
I should fix
etla: take a look at rs274/author.py
etla: you can take it from another one
er, no, that's one that's missing
look around in the python files, I'm sure one has a copyright

jepler: nice.. someone asked about that

etla: #!/usr/bin/env python
import sys, os
BASE = os.path.abspath(os.path.join(os.path.dirname(sys.argv), ".."))
sys.path.insert(0, os.path.join(BASE, "lib", "python"))
etla: ^^^ that works when the script is in bin/ or otherwise one level below the top emc2 RIP directory
how about emc2/lib/python ?
if the module is being imported then it doesn't have to worry about the path
the importer has to worry
jepler: how does that work for installed?
jepler: hal_manualtoolchange.py I mean
alex_joni: in run-installed the sys.path.insert should be harmless
if the directory doesn't exist, nothing is hurt
ah, so it finds it in the proper path.. got it
sys.path.insert just adds one more place to look
I wonder if it wouldn't be usefull to have widgets that trigger 'emc' things not only 'hal' stuff
alex: yes, probably through the emc python module
that's what halui is for
so you would have a hal_button and a nml_button
bit HAL only deals with BIT or FLOAT signals, and expressing everything with those is a bit cumbersome
jepler: I find it odd to have a slider in axis, which links to a hal pin, is connected to halui, and sends a NML message to emc
would emc2/lib/python be the correct place to submit ?
I mean commit

jepler, cradek: could we have the vcpparse script run when pyvcp=pyvcp_demo.xml is set in the [AXIS] part of the ini file ?
now the somewhat cryptic ~/.axisrc is required
etla: I'm working on "something better"
etla: it will be a line in the inifile
jepler: yes, that sounds good.
I'd also like to figure out a "useful" example control panel, to put in the standard configs/sim/axis inifile
that will require a matched .hal file to do the interconnects
with just one or two widgets in it
spindle speed display ?
well, something that makes sense in sim...
a diagnose screen would be nice
limit switches, step/dir leds, spindle on/off, ...
but maybe one pyvcp_demo.xml should remain which shows how all the widgets are used
etla: somehow sim/ doesn't feel the best place for it
that's all I use on my dev. machine
it would be nice to add some kinematics to servo-sim
etla: yeah, but it's probably the first thing users try
or maybe there is something there already ?
so it's nice to keep it simple
alex: but this will be like halui, if you don't activate it in the ini you won't see it
it does clutter the dir with one more file...
and one of the inis's with the calls to it :)
otherwise it's not really usefull to have there
I'm not saying that an different dir would be better though
sim/axis_pyvcp would be just fine for now also
thanks for all the help guys, going now, but I'll be back...

jepler: hooked some led's to the pluto - so far so good. pretty cool
just seem to work ;)
How fast where you guys able to read write to it? My period is still set at 100ms
1ms was fine on cradek's lathe
Should I play with lowering that?
100ms won't give you very good machine control :-P
I figured ;)
actually I think chris tried 500uS for awhile, but it didn't seem to make a lot of difference
jepler: what's in lathe.xml?
alex_joni: it's a pyvcp file that shows the spindle speed of the simulated spindle

jepler: read my mind.. thank you
wow, that's really cool
alex_joni, jepler, cradek, skunkworks, etla, and of course, the ever present CIA that watches over us all.
I've been (vaguely) following the VCP stuff.
cradek: where is the apostrophe, if any, in "happy new year's" supposed to go? and why is it there?
I was thinking we could stick that on the right side of the AXIS screen, and it might help the guy who wants a button to say which pulley his belt is on - oh look, a screenshot from the guys who get up earlier in the morning
jepler: in my happy place, there isn't an apostrophe there, and there isn't an "s"
cradek: "happy new year"?
jepler: thanks, same to you
Once upon a time I suggested the ability to output (and input) between hal and parameters. Output would be easy, but could be dangerous if used to control hardware. Input would be more difficult.
For now, though, there is enough stuff on my plate.
lerman: right, I remember
jmk, I think, was concerned that giving users the ability to gcode to the hardware would be dangerious. He was correct.
g0 X100 might also be dangerous
Although the user can already send the tool into the vise.
it's another way that makes gcode incompatible, even among emc2 users
Although I think some limit exceeded error might appear.
If they have incompatible hardware, that would be the case.
more than the usual though. say someone does tool change with a bunch of parameters instead of M6
I might want to be able to code my own version of M6. Of course, I can already do that with classic ladder.
gcode assumes a fixed model of a machine. Some of us (or some of them) would like to change that model, somewhat.
gcode should be a tool path description language that describes the part more than it describes the machine
For example, I would like to be able to probe (as soon as I get one) three points on a fixture and then be able to automatically align the axis in x and y. Then all of my standard g0, g1, g2, etc would refer to the new aligned coordinate system. To make things even more interesting, I would like the display (in axis) to show the commanded positions in the gcode coordinates, so I could follow...
cradek: seen that link with the hex cutting last night?
the pdf by fenn?
alex_joni: not yet, I only have one computer with flash and I haven't been there yet
oh I did see a pdf, yes
[17:00:06] <alex_joni> http://www.remsales.com/pages_blocks_v3_exp/images/links/POLYGON_MILLING_[Read-Only].pdf
interesting that the sides are only approximately flat
it was exactly as I pictured it :)
they can't be completely flat
even a facemill can't make a complete flat surface :D
lerman: this is where I sound like a nut, because I don't think probing belongs in gcode either, for the same reasons :-)
I wonder how long g-code will be still used
Probing IS part of the standard, though.
yes it is
thankfully, I don't have to like everything in the standard
but..but.. it's that standard.
no butts now
skunkworkwrk: plenty other standards around :)
it has a few crazy things in it - probing is one of the less crazy
I could use the probing I described and still have a compatible program, though. Just put in a test -- is probing available. If yes, do my probing; if no, tell the user to manually align the fixture.
:) don't change it too fast.. I like gcode
there - I said it.
My son does some blacksmith work. Has an anvil and forge. He describes himself as year 1000 ready.
So. How do we decide what 'changes' are acceptable in the interpreter. I say changes rather than improvements.
first we decide who is 'we'
1 -- Shouldn't break existing, standard conforming gcode
There's a blacksmith shop around the corner from me. He has/had a sign up that his products were all Y2K ready.
We is the community. acting thru the Board.
lerman: starts to sound like trouble :D
Being born is trouble. It's all downhill after than. :-)

hmm, the spindle readout on sim/lathe is in rps, not rpm
cradek: I think there's no way to avoid the raw speed being in rps, if its .position is to be in rotations
cradek: that's why i scaled it by 60 for display
maybe there should be a separate .velocity-scale
I don't follow
I mean the bargraph should be in rpm (I thought it was in your screenshot)
the bargraph is in rpm for me
it's not for you?

another one asking about axis reversing. http://www.cnczone.com/forums/showthread.php?t=29687
I wonder is puting a little comment in the ini file would help
somebody probably needs to make (or publicize if it already exists) a "quick start guide" for setting up EMC2 for steppers
step 1: use this procedure to calculate how many steps/second you need
step 2: use this method to figure out how fast your computer can generate steps
a one-page quickstart would be nice.
maybe skunkworks wrote most of it for that thread
it seems that way
I wonder if we could have the option of specifying the desired number of steps/second in the ini, and calculate the BASE_PERIOD from that ...

did jepler commit any changes to make the pyvcp load automagically from ini file settings ?
awallin: that is really cool, thanks
awallin: that's what you get when you run sim/lathe now
cradek: you're welcome, the code is probably a mess compared to what you're used to... ;)
haha you're assuming a lot about the existing code
nice. so there's a new ini parameter that points to the xml file ?
sorry I have no clue how it works, I just ran it
ok, but you did not have to edit a ~/.axisrc by hand
I don't have a .axisrc at all
I guess that was jepler's quick fix to get it working the first time
hrmmm, I get: HAL: ERROR: pin 'axisui.spindle-speed' not found

They also have a probe....
You can carve up a master, probe it, and recreate it...
cradek, jepler: with the new sim/lathe, I always get HAL: ERROR: pin 'axisui.spindle-speed' not found, HAL:1: link failed
it's working for you ?
awallin: you sure you updated all of emc2?
even the configs dir?
maybe you don't have the lathe.xml or you got a conflict merging the lathe ini
yes. could it be that I am under vmware, and thus everything is a bit slow ?
what's the '?' files I get when I do cvs update ?
I think I saw a commit message by jepler that he put a hal ready at the end of pyvcp
? is for local files which don't exist in the repo
M is for merged
P for patched
M for modified.. sorry
can I delete the ?'s with some command
that means you have a newer change than in the repo
no, but it shouldn't matter
I'm trying to run fenns flowsnake..py and get undefined sqrt. What do I need to do to get that defined? (syntax of import and whatever...)
if you do 'import math' then math.sqrt(2) will work
if you want just sqrt(2) to work you need to do 'from math import *'
from math import * worked
pretty cool video. neat little machine.
yeah! now I see the new sim/lathe working !

I apparently need to do anObject._getframe() ... What object would that be?
me either - I only know about that page because of Google ;)
Got it. The idea is this (after a discussion with fenn). I'd like to try using python as a gcode wrapper. In flowsnake.py, fenn used nasty looking printing like:
print "g1 f10 x", endX, "y", endY -- which looks like crap (to me). I suggested something like:
gcode("g1 f10 x#endX y#endY") instead. Now I know how to implement it. :-)

lerman: that's nice
lerman: what do you think of python?
Not too bad for me to read (I'm a C programmer). Hard for me to write (I'm a C programmer).
I guess it depends on what you want to do
im in love with python for making hacks
anonimasu: What were you talking about last night.... hex milling or something like that
I said the videos were cool as hell :)
just a sec..
[20:50:04] <SWPadnos> http://www.youtube.com/watch?v=oGq-9NNmr3o
I couldnt find it :)
Did they just vut a hex nut on that shaft?!
[20:52:18] <anonimasu> http://video.google.com/videoplay?docid=6346970134695813259
look at that ;)
will emc do that someday?
that's brutal stuff
it can just about do it now, but possibly only with HAL
what would it take to do?
a 2nd spindle?
driven tool.. that is
I'm not sure how one could configure the interpreter / TP to keep track of the second spindle
wth kind of cutter is making that hex nut?!?!?!
the second spindle is synced very accurately to the first one
standard cutters, but several of them
I'm not sure it's any "better" synchronization than multi-pass threading requires
SWPadnos: Um, it's spaced uniquely....
it could be done easily in HAL, the question is if the servo update rate of EMC is enough
that's a hell of a sync!!!!!!!!!!
you need a servo spindle..
you need 6 tools to pass the workpiece per revolution of the workpiece - so if you have a 2-slot head, it needs to turn 3x as fast as the chuck
or well, sync on both I think..
you need to sync the X/Z as well, I imagine
I doubt there's a PC for the controller! LOL
if you ship me the hardware for free I'll promise to make it work on emc ;)
if you look in the middle of it..
you see the tool slow down
awallin: Sounds like a plan, but we'll need your left testical as deposit.
Oh, does anyone work on TV's by chance? I have no color on the tuner, or video inputs. But have color on the OSD.

It worked the first couple of days, then no color at all.
no clue then

anonimasu Yeah, a couple of days ago.
oh no not yet (wrong router)

they are a pain in general
Had to buy a new frig yesterday, now it looks like the new frig is fubared too. *sigh*
Jymmmm: Just stay away from the wire running from the picture tube to the flyback.
My gf's monitor goes out, replaced it with a 17" which also went out. Then replaced that. Ten the 32" Tv goes out, and replaced that. Then the Frig goes out, replaced that yesterday, adn now it doesn't even set ice cubes yet and almost 24hours later.
is there something wrong with your mains?
Jymmmm: how's your power?
jtr Can't, need to disconnect it to be able to pull out the electronics.
what he said. ^^^
Hmmmm, This is a new place, but I don't think so. I checked which circuit is what, and now of the breakers are overloaded (I don't think)
You thinking brown outs?
no idea whatsoever it may be
I have a Kill-a-watt meter, maybe I'll toss it on and watch the line voltage.
I'm wondering if your voltage is high. should have two legs of 110, but if the neutral connection is poor coming into the house,
when you put a heavy load on one leg, the other leg could go up in voltage.
like 90/130 rather than 110/110
ah, ok. MAybe I'll borrow another kill-a-watt meter from work and see if I can figure out which circuits are on the first and second half of the 220
Nothing fancy... http://www.the-gadgeteer.com/review/kill_a_watt_electric_usage_monitor_review
Work just gave them out one year for Christmas gifts. This year was a network cable tester.
looks like a neat tool
This is this years xmas gift... http://www.compusa.com/products/product_info.asp?product_code=316202
While I'm thinking about it, I'm going to go plug in the kill-a-watt meter.
Well, I plugged it into the 110 outlet closest to the electric dryer. Got 119VAC. Turned on the dryer and it dropped to 118VAC
SWPadnos: solved my problem. Thanks for your quick google.
oh -- you're welcome
Jymmmm: the dryer is a balanced load, pulling equally from each leg of the 220 - very little from the neutral.
I can now write python with embedded stuff like:
g("g1 f10 x$endX y$endY ($Glevel)"
endX and endY are local variables; Glevel is a global variable and they all get substituted.
The only down side is that you have to write the line of gcode inside g("...").
Jymmmm: try loading with toaster, microwave, and other 110 loads.
[And you might want to know python if you care to use its features.)
jtr: Good to know. Will try the other appliances.
you can probably do something with triple-quoted literal strings, and so some pattern/varaible substitution on the string (using the python equivalent of eval() )
python rocks :D
Using the template class it's only a few lines of code -- once you know the magic to get the local and global symbol tables.
Pythons are reptiles -- have no rocks. :-)
I made a program to hook gnuplot for work..
and throw my data from our machines as a graph :)
pressures and stuff
lerman, I'm not a python expert, but it sounds to me like you're trying to solve a problem using python in a non-pythonic way :)
I'm not sure. I'd like the user to be able to not be a python programmer. Python I/O is a bit of a pain because of the quotes and commas.
It makes for a stepping stone approach where you learn just as much python as you can stand at a time.
But, you might be right.
jtr: Turned on/off the coffee maker and microwave... as each one was turned on, I saw it go from 119, to 118, to 117
well, I can't say for sure, especially because I know little of either python or the particular problem you'r eworking on
Its the alternative that cradek likes. Don't add subs and calls and named parameters to the interpreter. Instead, use python.
hm,. I like that also
jtr: This is a older place. There is only like one or two outlets that acutally have a ground.
so you want to use something like names params and stuf fin a file, and process it with a python program to generate code EMC can understand?
I 'spoke to' fenn last night and he also liked the python approach. So, I challenged him to rewrite the flowsnake program in python -- which he responded to nicely. I din't like the syntax of the print lines, so here we are -- the best of both.
Pretty much. cradek would (probably) just run the program as an input to Axis. I don't mind that, but I'd like axis to display the thing in source form and provide single stepping, step into, step over, breakpoints, etc. That would let us debug the stuff.
what does single-step mean when one "source" line may generate many G-code lines?
ve7it is now known as LawrenceG
or the opposite (several lines of source only generate a single G-code line)
A message like limit exceeded on line12345 doesn't tell us much without seeing it in the context of the source that generated. If we could feed the line to the interpreter in "real time", when the interp generated ad error, we could gen a python backtrace.
would anyone like to jog emc with the mouse-wheel ?
It's the opposite, I think. Show the line of source with the g("....") and then be able to see the backtrace.
I'd prefer a separate encoder wheel. I hate to think about the results when I drop the mouse (again).
03awallin 07HEAD * 10emc2/lib/python/pyvcp.py: the scale widget now responds to the mouse-wheel
the pointer would have to be on top of a special jog-area
and emc in manual mode
I would still drop the mouse and lose it.
But it would be fine for toy or hobbiest machines, I suppose.
I think I'll try it sometime later...
Jymmmm: I'm out of ideas - my speculation may have been flat wrong.
jtr: No, I'm not dismissing the fact that this is an older place and all. Why it's dropping a volt per appliance I have no clue.
jtr: If there is no/poor ground, would that affect anything?
I know crap about AC, Just that' their labeled hot, neutral, and ground.
and that 220 into the building is really one leg of 220 and enutral to get 110
two hots, 180 deg out of phase get you 220. either hot and the "neutral" give you 110.
can you get 110 from one of the hots and ground?
yes, but not a safe practice. ground and neutral are bonded together at the service entrance. or supposed to be.
if you are spliced, connected. when you read the code book, you start saying bonded - it's the term they use.
s/if you are//
Either one, I still don't "get it"
bonded = connected
tying two wires together is called "bonding"
"tying" doesn't sound like physically connected, or is it?
tied to ground ... connected to ground ... joined to ground .. bonded to ground ... same thing
Ok, then why is hot+gnd not as "safe" as hot+neutral, if gnd and neutral are the same thing?
eek, well, say they became disconnected at the inlet ...
now all your exposed metalwork is live!
my service entrance has a ground bus, and a neutral bus. Heavy jumper between them bonds them together electrically.
if the jumper comes loose, and you are using ground as a power return, your safety ground just went to 110v.
Ok, so say I turn off the mains. Take an ohm meter to an outlet. Both the neutral + gnd would (should) show 0 ohms?
Jymmmm, say, you decided to wire a lamp between the metal casing of the lamp in your dining room and hot ... and the ground lead in the lamp failed du e to flexing/breaking .. now what happens?
between neutral and ground, yes.
robin_sz: I'm understanding the "safety" factor now, just trying to figure out the difference between neutral and ground.
one is safe, the other is not
Jymmmm, electrically, theres not much difference .. but ground is not normally part of the supply loop, its a seperate protective circuit, a backup,
Also, ground might be a smaller diameter.
ground wires are often sized a bit smaller than the hot/neutral. they're also not sheathed (they're bare copper)
SWPadnos right, or green. Yeah.
not ALL building have them connected at the supply inlet either
fenn_ is now known as fenn
that only in PME .. there are other grounding schemes ...
what he said
protective multiple earth
SWPadnos: wtf? they have bare ground cables in the US? O.o
Rolmex has that
lerneaen_hydra, you are green/yellow like the rest of the planet for ground?
next you'll be telling me that they staple the wires to wooden beams
lerman: so i've been thinking.. how are we going to run python code if axis isnt present?
12/2 wire is white, black, bare
SWPadnos: what about corrosion?
Ok, if there is shitty wiring here causeing brownouts, is there anythign I could do?
copper doen't corrode much when it's at ground poential
How do we run any code if axis isn't present?
SWPadnos: I was thinking because of salt in the air and stuff
robin_sz I just moved in.
robin_sz and took 4 months to get the place.
lerneaen_hydra: and the bare wire is in the overall sheath
Jymmmm, its unlikely to be in-house wiring causing brownouts ...
unless of course you can smell burning
jtr: oh! so there is an PVC sheilding?
probably netural shifts doe to poor load balancing in the building
Jymmmm, buy a decent UPS for the sensitive stuff
[22:30:18] <Jymmmm> http://extreme.infomagic.net/static/romex_12_2.jpg
we have that in sweden too, though that's just local ground for a certain wire (there is a "real" ground wire in the cable)
Jymmmm, they will boost the voltage during brownouts
lerneaen_hydra: yes, two insulated and teh bare in an overall sheath.
Jymmmm: A line-interactive UPS will increase the voltage during brownouts
and an online one too of course
APC SmartUPS are nice
for a version of your code that lets you say:
robin_sz: Not proven yet, But my Gf's 17" went out, our 32" TV lost all it's color, and the frig went out and just replaced it yesterday (and looks like I'll have to call and have the new one serviced today as well)
g("g1 f10 x$endX y$endY ($Glevel)")
with substitution of local (endX and endY) and global (Glevel) parameters.
just dont put a) CRT monitors or b) laser printers on it
Jymmmm, coo, bad. get a UPS .. with the APC ones you can log mains voltage and graph it
Jymmmm, as for the frig ... did you move it recently?
The outlet that our computers are on is NOT grounded. I was planning on putting a grounding rod in and running a ground wire to the outlet. My UPS is only 1800VA, so I'm not sure it;ll handle all of our systems (less the CRTs)
Jymmmm: are you sure it's just not surges or generally shitty power?
lerman: No, I'm not sure of anythign at this point or even if it's power or just murphy's law
My fridge has a microprocessor in it; so it might care about the power.
Jymmmm, as for the fridge ... did you move it recently?
soft start motors
Jymmmm, and if you did, did you leave it to stand a full 24hrs before switching it on?
robin_sz The NEW frig, yes from the store to the house. But we never tipped it
fenn: seems stupid from a reliablility standpoint to have a microprocessor for that
24hrs my friend or the motor pumps the oil into the coils and .. goodnight vienna
lerneaen_hydra: one of us should change his handle... and since mine is my real name, I vot for you :-)
robin_sz It never went more than 30 degrees tilt
lerman: oh no! :p
robin_sz doens't matter huh?
lerneaen_hydra is now known as the_lerneaen_hyd
the_lerneaen_hyd is now known as lerneaen_hydra
30 is plenty .. trust me .. they die
Not enough characters.
oh, uh, maybe some client-level stuff?
lerman is now known as klerman
I personally stalk LH
and hydra and other permutations
Does this solve the problem?
lerneaen_hydra: know of a better way?
if it's ok with you then definetly
klerman, hi, you must be new here ....
Hi. You look familiar. Do I come here often? (Man walks into a bar and says...)
for some reason, whenever I see lerneaen_hydra I always think of something from greek mythology with a hea dof snakes or something
robin_sz: yep, that's correct
robin_sz: Ok, just unplugged the frig. Will 24h from now be long enough for the oil to drop back down and out of the coils?
one of hercules 7 (or was it 9) tasks was to kill the lerneaen hydra
Jymmmm, ummm ... do you want the bad news?
Jymmmm, well, is it just sort of running, but not actually getting cold?
robin_sz: it's spelled the lernaean hydra though
Both the frig and freezer are at 46F
Jymmmm, well, ive not know one recover yet ... but maybe you'll be lucky and be the first
How about hydra_lernaean?
I'm pretty sure that when we had out new fridge delivered, the delivery people pluggged it in for us ...
basically, if you switch it on too soon after moving it .. it pumps the oil out and thats that.
so it may not always be detrimental to turn one one after moving it
SWPadnos, so, and as a rule, delivery people have exactly how much intellignece?
not much, but our fridge has been functioning perfectly for the last 4 years ...
SWPadnos, well, if it was vertical all the time, maybe it would be OK, but if its had to go upstiars ...
About the same as us. But most if it is tied up with their gonads.
reaised ranch = up 1/2 flight indoors, plus 6 steps outside and a pirouette at the landing
While our intelligence is tied up with hardware/software.
SWPadnos, well, my gunsmith is an ex-fridge engineer and he explained all the reasons to me .. and basically, 24hrs is a really good plan .. you find they will run continously once they have pumped their oil out, they just stay on all the time and don;t get cold .. because it cant compress anymore
and turning off again and waiting wont bring it back
anonimasu, getting the oil out of the circuit is the first problem
or is it refridgerant you are talking about?
* anonimasu has nfc how it works.
Jymmmm, on a posiive note, you might just have disturbed a joint and released the freon, thats easier to fix
Take it apart, blow it out, put in new oil, suck it out with vaccuum, add new freon, etc.
or call the store and tell them it doesn't work ... :)
robin_sz, I'm not disputing that they can die this way, just pointing out that it's not guaranteed
If it's just low the freon, add a special fitting, add some more, (use your pressure/vaccuum gauges) seal it back up.
have the store guys fix it?
Is it new?
im pretty sure it's standard practice, about this kind of things
SWPadnos, agreed, but .. im afraid Jymmmm's have all the signs
I dont think they care about that 24h stuff..
at least the major one - fridge doesn't work ;)

that seems to know more than I do
Did you drop it down the stairs, or stand it on its head? Why would we do that? Besides I wasn't home at the time -- my husband was in charge of that.
why gmail might be flakey
that tip about carrying them suction-side down is not one I had heard of .. but makes sense
slashdot must be the world's lamest site..
all they do is post old stuff..
anonimasu: Thanks. I already disable JAVA and enable only as needed, guess I'll have todo the same for JS too. Though I usually connect to gmail via POP3, not the web interface.
oh, yeah, but that's probably why it's flakey..
anonimasu: POP3 is fine, but not ALL of my gmail accounts are setup as POP3 is the problem.
