there is suppose to be rigidity problems on that axis due to the way the lead screw nut is mounted
The Y on this thing, to be as kind as I can be, sucks BADLY.
Heh, I'm sure, it ain't a bridgport :).
so you confirm it
they are saying the X2 design is better
problem with the current Y is that by the time you get somethiing mounted to the table, you are already well out of the gibs.
Does not help with rigidity nor chatter...
Centered in the gibs, the quill comes down about on the front edge of the table.
more to the front than that actually.
Sucko big time...
I played with it at HF and there are 2 redeeming features on that mill - MT tooling and a working quill
it's not immediately obvious to me how the motors mount with that cncfusion kit
I really should just go ahead and order the damn Y extensions.
[00:03:13] <K`zan> http://www.cncfusion.com/images/X1mounts/X1assembly/CIMG3302.JPG
oh, now that is bad design
Same as any for the uMill...
using only two bolts on the motor faceplate ...
same idea whether you use channel, plates and bolts or whatever.
not that there's enough power there to strip an 8-32 screw ...
how much power does it take to strip a 8-32?
dunno - but I can do it, so it's probably under 200W :)
Probably more than the 276 in/oz I am looking at....
it's a torque thing, not power
and 276 oz-in probably wouldn't do it, depending on the screw material
Oh... okie so I am safe with the 200in/oz motors ;)
have you looked at the taig mounts? that might be more secure
yeah - 200W and 200 oz-in are very different
If I thought a bridgeport would not end up 4 floors down in the basement, I would probably just save my $$$ :).
LOL, sure would be a LOT less frustrating :-).
don't bet on it ;)
Actually I suspect a bridgport (clone) would neither fit in the elevator nor fit up the stairs :), so I guess I go with what I got...
I have yet to make motor mounts for mine (it's been less than 2 years though ;) )
You have a uMill ?
no, I have a Bridgeport
For a moment I thought I might not be alone here :).
they're not necesasrily less frustrating, and you can't exactly lay them on their back for easy access ;)
There IS that :-).
well, you may be able to, but standing them up again is a real pain
luckily, it's only a ton or so
Fork lift or chain hoist....
not in my garage, unfortunately
This wooden building would not support one and my landnazi would have a heart attack...
in fact, I have to be careful about where I wheel it - the head is high enough to take out the flourexcent bulbs ...
Hummm, it MIGHT be worth it for that :-).
Tough life ;-) </envy>
I'm sure my wife will be even happier wehen the 3000 pound lathe comes :)
Tough life ;-) </HEAVY_envy>
though it'll be me who can't park in the garage (still)
Gotta start someplace, sigh, I didn't know how good I had it when all I had to do was write programs for the moogs...
I could really use a 1000 sq-ft shop with 12 foot or higher ceilings
In seattle that would pretty much mean loosing your transportation...
or a lot of damage rather constantly.
here it pretty much means losing your wallet
ie, it's rather costly
If I may ask.
specifically the Burlington area
Same here, accounts for the ludicrisly high government mandated insurance...
Wish I could get the gov to do that for my business...
Lot of industry there, lucky you.
not here, for the most part
there used to be in the southern part of the state - in Springfield
Thought that was pretty heavy industry.
you have to get the right Burlington :)
* K`zan avoids coasts anymore...
no - a fair amount of high-tech (IBM has a fab here, and IDX - now GE healthcare software)
not much in the industrial arena. I went to Buffalo for my mill
strangely though, I"m getting a very niec NC lathe from about 5 miles away
with a mill, around the block is a long haul :).
from an aerospace shop
it's the last 20 feet that make all the difference
most liftgates are only rated for 1500 pounds or so ...
Once we get out of scabattle and out of frugging apartments, a lot of things open up for me.
so the milling machine is a bit to big (200 pounds), and the lathe is away too big (3000 pounds)
get a barn
Yeah, read enough stories about that kind of thing on r.c.m
or a garage with cathedral ceilings ;)
Here if you do industrial stuff, you are sort of evil, but good for much taxing...
I'd be happy to just have a room all to myself :-) for a start.
[00:19:20] <K`zan> http://wrlabs.shacknet.nu/~vw/MyMachineShop/
Entertainment for you folks with real shops :)
heh. if I had a photo, you'd shudder ;)
Something about "the grass is always greener..." LOL
if only I had heat in the garage ...
it would be better for the machines, that's for sure
just use the shops at the JC
I'm not sure they have any metalworking equipment there
(we don't really have a JC around here)
Sterting to wonder how much machining is left in the USA other than the hobbiest...
there's a technical/vocational center next door to my house (for the most part), but I don't know what they have, and what's usable by the community
not much. americans are too greedy, on the whole
Sigh, it does seem to be a rampant disease these days :-(.
there is still stuffrelated to aerospace and military, because we're more paranoid than greedy :)
That is probably very wise...
Just because we are civilized (such as it is) does not by any stretch mean the rest of the world is.
"Just because you are paranoid doesn't mean they are not out to get you" -- Sign on therapist wall...
let's not go there tonight. there's plenty of other stuff to think about
Yep and nothing we can really do about it anyway.
Just keep your powder dry and plod on...
Back to figuring out where to start....
replace it with an X2 or X3 ;)
Probably wisest to just get the Y table mod.
Heh, I wish....
the X2 isn't that much more
Right now I'll keep most of my coins to get out of this sewer.
thought HF has that around $420ish
table ~= $100 with shipping.
since it is a store item, it qualify for 20% off coupons
Maybe / probably once I get out of here and can justify the expense. Any machining where I am heading might mean paying work :-).
Always nice to get paid to play :-)!
At the moment this is ALL educational and one does indeed pay for education :).
are you a student?
I was at Cabin Fever over the weekend, and there were a lot of guys running Mach3, but none with EMC2. So I decided to ask a fellow who was selling circuit boards and exhibiting a mill controlled by Mach3 what he thought of EMC2 and the pros/cons compared to EMC2. Turns out I was talking to Steve Stallings. He had nice things to say about you all. :-)
ds3: Not at any instituition - all on my own.
K`zan: then what's the difference if you get paid to do machining or not?
None really, but it would be nice if it happened :-).
Always nice to have a hobby pay for itself.
And right now all I can call it is a hobby.
a lot of hobbies cease to be fun once you get paid for it :(
True, but a good while back I worked at it and really enjoyed it.
For some reason mechanical stuff is just fun.
Getting there (cnc) this way IS a bit trying at times, to be sure :-).
the alignment and final tweaking might be more annoying
Yep, I can see that coming to be sure.
LOTS to do.
LOTS to get right...
you got the indicators and clamps for them?
Got indicators, no clamps yets as damn near everything is going to get changed out (x and y).
by clamps I mean holders
Spending an awful :) lot of time planning at this point.
end mill? collets?
holders for the indicators
be it a magmount, one of those flexible thingies or whatever else you like
Magnetic holders at this point which is mess with the uMill.
Very limited spaces to clamp to.
Lost the Z indicator when I went to the belt drive.
always a bent rod in the collet
Got to come up with something to replace that.
Yep, can and do that.
setup a DRO =)
Heh, LONGway down the road.
If at all with this mill.
might be easier then replacing a micrometer collar esp. since the screws are part metric
Might be easier, but on my budget it is undoable.
"On the cheap" takes on new color and dimension here :-).
$12 + some creativity is still too much?
Where did you find DROs for $12?!?!?!
HF digital calipers are $12 on sale
look up the shumatech DRO for a built out system based on them
Yes, that could be done and perhaps eventually will be.
Seen a few people that have done basically that.
but since you are going CNC, all you really need is some clamps to hold the caliper down on the Z axis and be done with
it'll come off after CNC is finish
Still a nice thing to have if you have to do anything manual.
hehe... just use the jog function
CDCO Machinery sells some decent/cheap DROs
grrrrrrr perl is confusing "00", "0", 0, and undef :/
CDCO does have decent prices on those!
cheaper then the shumatech stuff?
IIRC 150mm is what I get with the expanded tables on the uMill.
chase all over for shumatech pricing...
you decided what to use for limit/home switches yet?
was considering hall effect sensors, but that is by no means written in stone at this point.
As noted, I am doing a rather fantastic amount of thrashing at this point :-/.
found any comparisms for limit switches? trying to figure out what I want
Just barely into researching that. Mechanicals have various problems as do the hall things.
Hall, at this point, seems easier, but I may be wrong there.
Liked this one:
one thing that bugged me is the lack of room
03fjungclaus 07TRUNK * 10emc2/src/emc/usr_intf/axis/scripts/axis.py:
Have the .ini file setting INCREMENTS in the [DISPLAY] area working
as described in the manual ...
ds3, I don't know what schumatech charges, so I'm not sure. CDCO charges $175 for a 3 axis display.
owad: does it include the scales?
My bookmarks are getting to be a real mess :-(.
that is comparable to the shumatech kit
[01:09:46] <K`zan> http://www.balbots.com/article_info.php?articles_id=10
What's shumatech charge? I was just looking at their website, and there wasn't any U.S. order link
shumatech is a kit
you order the parts given the BOM from Digikey or mouser; the board is the only non OtS part
The shumatech enclosure looks sturdier
guess they don't actually sell that enclosure though, looking closer
"machine your own"
CDCO is somewhat cheap-looking plastic
wheeeeeeeeeeeee G code post-post processor works
is there a way to capture the output of axis into an STL?
its what i've been working on this week actually
apparently jepler has been doing stuff in "secret" and made a lot of progress
that would be almost prefect now that I kind of have a haas to EMC post-post processor working
hmm did the logs move?
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2007-01-23.txt
[02:18:32] <fenn> http://emergent.unpy.net/files/sandbox/gdepth3.png
maybe I am missing something but is the G76 (multipass threading) in EMC fanuc style?
dunno if a consensus was ever reached regarding threading codes
is there a page describing g76?
[02:21:39] <fenn> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Lathe_Advanced_Features#Canned_thread_turning_cycle
no wonder I can't find it with a search for G76
blah seems only G33 is implemented
ds3: wow it seems a lot of progress has been made today while i was asleep
ds3: here is a script that previews your gcode output http://emergent.unpy.net/files/sandbox/gdepth.py
python gdepth.py -t .3 -x "-2.1 2.1" -y "-2.1 2.1" -r 200 -o spiral.png emc2.cvs/nc_files/spiral.ngc
fenn: I'm glad you like it -- did you get it to run on your system?
ds3: see g76.ngc in cvs
no, i think i need to install an updated gcode module
then i got distracted looking at the source
fenn: it's my usual scatter-brained approach to coding
hmm.. python2.4/site-packages/gcode.so is from cvs but i get
code, seq = gcode.parse(args, Canon(), 'g20 g17 g64', '')
AttributeError: 'module' object has no attribute 'parse'
are you getting the gcode module you expect? python -c 'import gcode; print gcode.__file__; print dir(gcode)'
['__builtins__', '__doc__', '__file__', '__name__', 'gcode']
python gets modules from the directory where the script resides before any other location
put gdepth in its own directory or rm gcode.py gcode.pyc
ok its cranking now
wow... that's great
looks just like the real thing eh?
subject to the resolution you can handle waiting for
I swapped my machine to death earlier trying to do a PCB gcode file at 500dpi
100 dpi is quite usable
and certainly fast enough
officially announced: http://axis.unpy.net/index.cgi/01169521961
how long did that take to write?
fenn, your script requires an installed EMC?
yes of course
otherwise how would you be sure that EMC does the exact same thing?
I'm running in place at the moment
well, sudo make install
I need to rebuild to do that
but that's fine.... I want to finish my HAAS to EMC script
jepler: something broke between version 0 and 0.1, now all i get is a red square
wow this is a complex g76
fenn: hm, really?
that's no good
fenn: try this commandline: ./gdepth.py -t .3 -x "-2.1 2.1" -y "-2.1 2.1" -r 200 ~/emc2.1/nc_files/spiral.ngc
fenn: are you using the "acceleration module"?
ds3: the tapered start/end stuff isn't in 2.1 - it's not quite done
it draws the .png fine
ds3: so ignore "e" and "l" but I think everything else is there
cradek: still a lot of parameters compared to what I am translating from
you can probably leave out the ones you don't need, they have sensible defaults
ahem - sensible, undocumented, defaults
what is required?
jepler: ok, "make" fixed it :)
if I still see the tip of the tool at the end of the cycle, I am happy =)
ds3: probably just drive line and depths
yeah no kidding
fenn: hm it's probably something obvious
but you probably want compound slide angle, degression, and spring passes for any real cut
unless your controller cuts straight in? I hear some do, but I can't imagine that working very well
isnt' compound assumed to be 30 fix for UN threads?
fenn: if you care to fix it in your local copy: http://pastebin.ca/325332
most people use 29
at least that's how I was taught to set a manual lathe
you don't want the right side rubbing, you want it to cut a bit
I been told 29, 29.5, and 30
(huh, most of the time is spent shoveling the data through glVertex calls to make the display list?)
as you please - that's why it's a parameter
except I am writing a translator so it'll be hard coded as I don't think Haas provides it
do they do 30 or 0 or some other number?
donno, they have at least 3 different codes for threading. Going to go dig out the manuals in a few minutes
someone at fest told me their control only does 0 (no compound)
might depend on the G code used
fenn: "0.2" uploaded
with the accel module, you mean?
yes, i think..
Something tells me I should have installed the ubuntu system here from the EMC CD rather than the regular, sigh. Ain't hindsight a wonderful thing :-/...
a few updates?
Not sure what it would take, need to take a look at adapt and see if EMC is even there.
the emc cd is getting old too, but not as bad as the original dapper disc
K`zan: there are simple install instructions on linuxcnc.org
Will take a looky see, the CNC box is in the shop and isn't networked (yet).
it's dapper right?
Nope it isn't available through adept...
err 6.06 LTS
we don't build releases for edgy
edgy is not the preferred path
you should use dapper if it's just for emc
Linux witch2u 2.6.17-10-386 #2 Tue Dec 5 22:26:18 UTC 2006 i686 GNU/Linux
Which means starting over with ubuntu on this box...
the install is trivially easy
Heh, as I said, something about hindsight :-).
Yes, but getting everything back will take a while again.
Finally about got this up to where the gentoo box is.
For my use.
Maybe just drag the emc box back in here since it is going to be a while before I get CNC together :-/.
Got two spare slots on the KVM :-).
K`zan: i've used skate bearings (non-angular contact, shallow groove) and they do work, and better than a plain bronze bearing, but you can tell it's stressful for the bearing so they may not last a long time
fenn: That has gone on the back burner for now, until I can get the right ones...
are they going on when you cnc it?
Yes, once I get to it all :-).
anyway you need either angular contact or both thrust and radial
Still thrashing a LOT on just what to do.
03jmkasunich 07TRUNK * 10emc2/docs/man/man9/pid.9: man page for PID loop
Spend all this time I am waiting to be able to afford drives and motors deciding whether to throw money at it (heh) or make something
Biggest problem is the dis and re-assembly process. Once I have two mills, life gets easier :).
you mean make a drive?
I should be spending some of this time learning to make G-Code do what I need while the rest is pending.
or make a mount kit
or wind your own steppers :D
or you could make your own servo drives ;)
fenn: I did that for a floppy stepper, but I am pretty much decided to forget the xylotex drives and get Geckos
AVR and a ULN2803...
yeah a real motor driver is a lot more involved
True, I could cheap it, but that is getting as discouraging as the "savings" would be...
The more I watched the xylotex group, the more that just seems to be a bad idea, no matter how cheap it is.
Just seems to be really "delicate"...
Jymmmmmmms experience is also not encouraging.
hey everyone, having a problem with some gcode to do a circle, getting back a message that all axes are missing motion
Sure you set feed rates?
in tthe gcode ot ini?
* K`zan is not God's gift to G-Code :-).
In the code yes, got the be there to move anything.
if it is 1 or 2 lines - paste them here.
otherwise use pastebin.ca
Hey skunkworks - you work for Lockheed :-)?
03jmkasunich 07v2_1_branch * 10emc2/debian/emc2.files.in: add manpage for PID loops
03jmkasunich 07v2_1_branch * 10emc2/docs/man/man9/pid.9: add manpage for PID loops
There are canned routines for circles IIRC?
feed rate 20 N3 G3 I-0.5 J0. F20.
k`zan: na - just own a dodge stealth ;)
feed rate 20 <-- don't think that is legal G-Code..?!?
you need x an y posistions
:-) Good start :-)
what is your post-proccessor?
:-) Good start :-) Dodge that is :-)
its really a mitsubishi
feed rate 20 was just a reply code started with 20 lol
was using code that was previously run on mach3
guest156: you need the end position of the arc in x y cordinates.
emc2 uses the nist standard gcode.
* K`zan hasn't done g-code in over 10 years now, so she will now shut up.
ok tried the emc post under bobcad but it doesn't set that
[04:12:23] <skunkworks> http://axis.unpy.net/files/gcode.html
usually fanuc post works with minimal mods
rum and orange juice is starting to taste too good.
* K`zan is a vodka and orange juice fan :).
Will have to try rum someday...
itssss not toooooo baddddd ;)
fanuc doesn't give ending coords either
Wonder if the mini-mill uses those damn plastic gears...
guest156: then there must be a setting in bobcad to put the x,y coordinates in the g2,g3 commands
ds3: if you're still here, look at nc_files/g76.ngc
* skunkworks doesn't know bobcad
Wonder if Homier ever has anything in stock for over 5 minutes ?!?
:) it is all on thier trucks driving around the us
a full circle has to specify XY the same as the starting position
G0 X1 Y1 / G2 X1 Y1 I.5 J0 will make a circle 1" dia around x1.5 y1
oh, he left
I did a quick search for bobcad post options and didn't find anyting
maybe some controllers accept that as-is, I don't know
nice thing about standards is there are so many to choose from
fenn: looked there, thanks.
oh so the I-J notation will let you do full circles? (vs max 180 w/the R notation)
ok, added emc output for gcam
Hmmmm isn't g76 over defined?, that is, for a given geometry, isn't pitch tied to thread height?
(or does K mean something else)
webcam to emc?!?!?
Wow, that would simplify my life :)
No such luck :-(
oh my U/W notation is not support it seems
guess not since threads are trucated
* skunkworks doesn't use R notation for g2/3.
gcam looks pretty useful!
looks like it needs fortran...
R notation is handy when you have circles that end at odd places
lots of theme packages, but no gtk :-/.
eventually I guess gcam will be installable or ubuntu will get gtk.
i'm sure ubuntu has gtk
or does it need a certain version?
fenn: Not sure, need to look at the config.log and see, IIRC > 2.0
conftest.c:26:21: error: gtk/gtk.h: No such file or directory
configure:18725: checking for GTK+ - version >= 2.10.0
configure:18870: result: no
configure:18948: error: GTK+ 2.10 or higher is required
Look at it all more tomorrow, kind of too tired to mess with it tonight.
I know I have that under gentoo, so worst case I can try it there.
i have libgtk2.0-dev version 2.8.20-3
does that make sense?
just dl and compile it
fenn: Could do that, I am just leary about spreading unremovable things too deeply...
Wonder why it isn't available through portage (or whatever they call deb package system)?
Lemme try something here.
Heh, like a dictionary :-), it helps if you know what to specify :).
Hauls in 31 other packages with it :).
Finally got all the libraries loaded (I think) but make blows out with:
gui_opengl.c: In function 'set_projection':
gui_opengl.c:384: error: 'M_PI' undeclared (first use in this function)
i came across some video tutorials that may be handy for newbies like me :) (python & blender) http://showmedo.com/videos/python
tomp_, repost that to the emc email list maybe? cradek, jepler, and alex_joni would probably be interested.
A_L_P_H_A: i came across it looking into vpython, which is even more important, i just used synaptic to get idle & vpython, & now have scriptable 3d , something like what jepler did today but animated, but maybe not cgs like jeplers ( subtract one volume from another to simulate tool cutting workpiece)... but will post
A_L_P_H_A: i had better luck runnning vpython from eric (ide) than from idle (ide)
alex_joni: regarding jepler's work yesterday, there's some tools 'vpython' available in universe. 3d scriptable scenes with animation

ah, building a box so I can install MythTV on it.
You gotta love it... dl the latest distro, burn it, install it, and upon first boot it says you have 104 updates.
I'd prefer kubuntu, but it has install "issues"
you can always switch later
sudo apt-get install kubuntu-desktop
sudo apt-get install xubuntu-desktop
sudo apt-get install ubuntu-desktop
sudo apt-get install edubuntu-desktop
I'll uninstall a LOT of things afterwords. Don't need all the overhead for the frontend box
I can understand
I'm only going to be using the front end as a video jukebox.
there was a linuxvdr project I think
[10:31:45] <alex_joni> http://linvdr.org/projects/linvdr/index.en.php

hey all, circle with flat edge problem here, can anyone help out?
Guest291: if you extend that a bit :)
backplot shows a circle, when i run the code it draws a circle with flat edges
if you run it slower, does the shape change?
will try it
I'm assuming that this is emc 2.0.5 and you've modified the ini file for some reasonable speed and acceleration settings
have you ruled out backlash as the cause?
yep modified the ini, backlash comp is on 0.0034 now only flat sopts on the sides
I still believe it's backlash
can you take a picture of what it looks like?
i dialed in my backlash with a dial, imagine a donught thats been in a small box :)
how big is the circle and how long are the line segments?
this is programmed with G2 or G3, not a CAM program that outputs a lot of G1s ?
circle is 1" dia arcs are about 0.25 the rest flat
N4 G03 X0. Y1. I-1. J0.F30
N5 X-1. Y0. I0. J-1. ... etc split into 4 segments
do you have G64PX.XX at the top?
whats that one?
that will set a tolerance for the blending, try G64P0.01
i.e. stay within 0.01 of programmed path at all times
also tell us about your machine, what are the leadscrews and nuts? what are your acceleration and velocity settings?
are you using AXIS gui? if so you will be able to see how close the red and white lines are, which would rule out a software setting
you might also try doing a single 360-degree circle, to eliminate the joins between different motions as a cause.
another good idea
stepper or servo ...
g0x1y0 / g3x1y0i-1j0
nope can't run axis going through vnc
strange. it works under Cygwin for me ...
if i export a full cirle my preprocessor doesn't snap in the coordinates
just write it by hand and test
cygwin using an xclient right?
cygwin is an X client on Windows
SWPadnos: vnc is based on xfree86 3, which does not have opengl in the xserver
xf4vnc provides two implementations of VNC in an Xserver. Both implementations are built around XFree86(tm) 4.x which provides numerous new extensions, such as RENDER and GLX.
* All features from tightVNC 1.2.9 included,
I wonder if it's stable/working
I sit corrected
ok g64 continous gives flat sides
you probably need to pastebin your g-code and your ini file for anyone to have something smart to comment...
ok how do i do that?
or do the things people already suggested
[15:05:55] <SWPadnos> http://pastebin.ca/
i tried g64
G64P0.01 will set the tolerance, G64 by itself is not good if you have low acceleration values
oups thats supposed to be a p
does emc take backlash setting into consideration on doing a circle?
yes it should, but you could try running your code with all backlash set to zero
what emc version are you using?
your X acceleration is 1, but Y and Z are 20
is that really what you meant? is X underpowered?
VEL and ACC values in [TRAJ] should be set lower than VEL/ACC in [AXIS_N]
that's not true
awallin, not necessarily
the vel/accel in TRAJ are vector sums of individual axis vel/accels
ok, so sqrt(vx^2 + vy^2 + vz^2) ?
usually they should be higher, since TRAJ limits in every direction, even diagonals, which can go faster
which would be sqrt(3)*v if all vs are equal?
Guest291: what do you have for leadscrews and nuts?
gonna go though my config again
so I'm only off by 1.7...
it's a sherline mill, I'm running 196oz steppers on it
are those the steppers they sell with it?
awallin, heh. "within an order of magnitude"
ok then, I was surprised you had those going 60ipm :-)
75 is my top
then they start stalling
how long is the flat spot?
(in the individual axis sections - only 60 in TRAJ)
(should be able to calculate the actual backlash from that if you know the circle and cutter diameter - shouldn
sin(x) ~= x for very small x, so it
well i did backlash with a dial gauge ...
it's not any easier to measure it that way
right - but he can compare it to what the dial said.
true. though the 0.0034 backlash should be a little bit hard to measure on the circle ;)
sounds like it is pretty big though from the description.
yep - I got that impression as well
flat sport is allmost 1/2"
on a 1" circle?
more like a square with a round bottom and top
how wide is it across the flats?
let me get the piece out and measure
by the way you should really run the update to 2.0.5 - I promise it won't break anything, and it fixes a few bugs
what size cutter?
right now trying to setup cygwin
and no G41/G42?
[15:20:27] <cradek> http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/debian/changelog?rev=184.108.40.206;only_with_tag=v2_0_branch
nope no g41/42
try replacing lines N4 and N5 with a single line: N4 g03 x-1 y0 I-1 J0 F30
hmmm - no, do that on lines N5 and N6
leave lines 6 & 7?
so leave N4 alone, and make N5 X0 Y-1 I- J-1
and remove N6
oops - there should be a1 after that I: I-1
argh - man, I need more coffee :)
ok, N5 X0 Y-1 I0 J-1
that should just do one 180 degree arc that goes across the X direction reversal (which is the problematic one)
x is still flat
I'd fix the accel as well
have you tried it without backlash?
also at slower speeds, like F5 or something
do you have to restart emc on ini changes?
err - F2 even
that accel is VERY low and might actually be the whole cause
I think arcs use the same (lowest) accel of any axis which has arc motion
but wouldn't g64p.001 fix that?
I think it should, but then you're going to virtually get stops at the quadrants, which will mess up the part too
not seeing it. (doesn't take much though)
paste your ini again please
03jepler 07TRUNK * 10emc2/src/emc/usr_intf/axis/scripts/axis.py: earlier change accidentally modifed DTG default
[15:38:27] <Guest291> http://pastebin.ca/325734
now your acceleration is 1 on both X and Y. Try 20 instead
k, got axis running atleast :)
at these settings it will take an entire second to get up to full speed, then another second to stop. Your motors can do much better than that!
although even at these wrong settings I get excellent path following (because of N0 G64 P0.001)
ok will try that, gotta run off to work, thangs again will keep plugging at it and re-read the ini docs :)
awallin: there's a bug in that tooltip, the extra window doesnt get destroyed on exit
oh one last thing couldn't find anyware to set the step pulse duration?
ok, later Guest291
Guest291: you can find that in the hal documentation, or with 'halcmd show param'

awallin: For now I think I will try to create a complete geometric hierarchy, if certain functions turn out to be to slow they should be easily replaced by C/C++ code
I want to take a minimalist approach and just define the types required to represent any object, however it's not very efficient to define a circle as a NURBS curve and simpler representations should be added later
Dallur: ok, keep us posted on what you do!
brb, getting good

Dallur: here's a page on profiling python code, with some steps for getting adequate performance: http://www.onlamp.com/pub/a/python/2005/12/15/profiling.html
jepler_: do you have a version of psyco on your 64-bit install?
ah ok. I was trying to see how it would do on gdepth, but psyco isn't available (packaged) for 64-bit
in fact, it's x86 only, but I figured it might work anyway
SWPLinux: try gdepth 0.2, it has its own speedup module which does work on 64-bit systems
ok. is it at the same place?
using hotspot, I saw that triangle() takes most of the time (with make_list() a relatively distant second)
of course, I somehow managed to screw it up so it only shows the +,+ quadrant ...
SWPLinux: I didn't hotspot it, but it is the "triangles" stp that takes the most wall time
yep. 19.3 seconds, of ~25 total
on my system, callgrind shows 50% of the cycles are inside nvidia's libGLcore
_gdepth.c:triangle accounts for only 85M cycles out of 3G
ok. gdepth0.2 is much faster
all we nede now is a multi-threaded version ;)
I don't really see anything about _gdepth.c:triangle that can be optimized
thank you for your fix in AXIS
fjungclaus: yes, thank you for fixing that. I appreciate it.
Hi! Good evening to all ...
SWPLinux: on my system this gives 4s user 8s wall: time python2.4 gdepth.py -t .25 -x "-2 2" -y "-2 2" -z " -.3 .05" ../emc2/nc_files/spiral.ngc
I'm still fighting with the setup of chatzilla ... so give me some time and some more join&leave-cycles :-))
fjungclaus: that's ok :D
I think SWPLinux uses that too - so we're used to his join&leave cycles
SWPLinux: just doing the calculation part is about 1.6 seconds (the -d flag except that doesn't work in 0.2)
I've got it running here also.
hard to tell, since the time includes how long you view the result
but it's a lot speedier
Hi, Alex. I've been away from emc for nearly a year, but you've very actively supported the emc-users @ peter's cnc-ecke, as I've seen!
(like real 3.63 / user 2.37 seconds)
fjungclaus: we all do out part
SWPLinux: if you hit the window close button it'll exit right after preparing the display list
ah - o
@Jeff: "I appreciate it": Does that mean the patch is working? :-)
2.832 / 2.128 in that case
fjungclaus: yes, it worked for me too
SWPLinux: in gdepth.py on the line with getopt.get add "d" to the end of the string. then run with -d on the commandline
SWPLinux: this will tell me what fraction of the time is spent in each phase (calculation & display list creation) on your machine
SWPLinux: I had the impression last night that it was maybe 1:4 on my athlon64, but it seems to be more like 1:1 on this machine (with a slightly different version of _gdepth.c)
fjungclaus: try /msg it works better
real: 0.691, user: 0.632, sys: 0.060
SWPLinux: so 1/3 calculation and 2/3 display list creation
closer to 1/4
err - unless you're using the "user" numbers ...
yes, "user" is CPU time, "real" is wall time
user+sys seems to jive well with wall
though not always, as I can see in a different run
is this version any faster? http://emergent.unpy.net/files/sandbox/_gdepth.c
it won't serve files with a leading underscore,
[19:51:58] <jepler_> http://emergent.unpy.net/files/sandbox/underscore_gdepth.c
(rename before using)
jepler_ is now known as jepler
slightly better: 0.666 / 0.604 / 0.064
this was an optimization of the display list creation step -- remove -d from your commandline again
2.635 / 2.016 - still a little better
were you trying to get gcam to work on ubuntu dapper?
Yes, and it won't compile under either ubuntu nor gentoo :-(, same error both places :-(.
this makes gcam compile with gtk+2.8: http://emergent.unpy.net/files/sandbox/gcam-2007.01.09+dapper.patch
Ah, edgy here, does that matter?
was the error that you didn't have the right version of gtk+?
if so this patch will probably work for you too
No, finally tracked down the needed stuff for that, hold a sec, lemme grab it.
that patch also fixes an error about M_PI being undefined
those are the two problems I ran into compiling gcam on dapper
That was the one :-o:gui_opengl.c: In function 'set_projection':
gui_opengl.c:384: error: 'M_PI' undeclared (first use in this function)
Lemme see what it takes to apply that...
patch -p1 (or maybe -p0) < gcam*dapper.patch
p1 :-) worked.
lemme give it a shot! Thanks!!!!!!!!!
worked! Lemee see if I have to make install..
Comes up! Coool. Verrry Coool :-). Many thanks. Now to figure out what to do with it :-). Will see if I can make the tool holder part for the QCTP :).

Heh... Just how many years do we have accurate climate data for?
the Royal Observatory has been keeping track of some things (like temperatures) since 1659
I still don't buy it...
and polar ice cores give data going back ~650000 years
Much talk about ice pack melting, but not a word about the areas where it is thickening...
"Insufficent data" and emotion is not data :).
on a climatological scale, there aren't any areas of thickening
Err, yes, there indeed are.
rwmwmber - "weather" isn't the same as "climate"
remember, that is
Yep, quite well aware of that, something gory misses completely.
LOL, usually here. Funny we get discussions here rather than emotional ranting, quite refreshing.
My climate requires COFFEE, bbiaf :-).
what, too much water in your caffeine system?
too much blood
blood ~ water
some other odds and ends
blood is thicker than water (expecially if you're high in iron)
still the main component is water
of course you've got various organic compounds (like haemoglobin)
well.. it is the main component of the human body :)
yewah - all you have to do is watch that Star Trek spisode, and you'll know all about it
uh-oh, one of us doesn't know his star trek
SWPLinux: no real treckies around here
the one where they went to the "primitive planet" where iron was toxic?
sounds like something from the original series (shrug)
some crystal? alien thing called the humanoids "ugly bags of mostly water"
becuase it's oh so likely that a planet will be nearly deviod of the atom with the lowest atomic energy
LH: right on
it's the TOS episode where several people get turned into little polyhedrons of minerals
"the other 2%"
and let me guess, they're back to normal by the end of the ep?
only the main character that was affected ;) the others were "red-shirts"
they used the uh ... transporter to ... rehydrate them
no wait, that's the other half of the episodes
no, they reversed the alien [TECH] device to put them back
man those were pretty bad weren't they
they used a phaser to capture the humidity from the planets atmosphere
I just saw one of the fan-made "Star Trek - The Continuing Voyages" episodes in a movie theater
Anything with William Shatner in spandex and high heels can't be good !
it had better production value than TOS
Which would cause less latency ya think: 700MHz w/ 512K cache -OR- 1000MHz w/ 256K cache ???
same processor family?
hmmm. is one a celeron?
I don't think so, both "should" be full P3
ok. bus speed?
what's your target BASE_PERIOD? Either is likely to be fine for 20us
No idea on the buss speed. But with the 700MHz I can get 18000
I have a PIII that I ran at 20k, but upped to 25k becuase I wanted better non-rt performance
well, try the 1GHz one and tell us which was better ... :)
SWPLinux Ok, fair enough. I just had ALL the systems torn apart atm and going Hmmmmm, what if I..... =)
if the bus speed is the same, then I'll bet on the 1 GHz one, but not by much
it depends on the chipsets as well. if you have the time, try swapping CPUs and see what happens
Same mobo, just swapping CPU's is all
Oh Slot1, so they HAVE to be P3, right?
wasn't the P2 available in some slot thingie?
Maybe, but these say Pentium III on them. But not sure of "celeron" was available in Slot1
Slot1 can be either a PII or a PIII processor
Well, I'll play later with it as I'm not ready anyway. Working right now to build up the front end MythTV box.
PII are <500MHz, PIII > 500MHz; you can adapt a Socket370 to a slot1 board
I just using what I have on hand, no need to buy when you have shitloads of systems laying aorund.
sounds like me
I bought nine system from work for $6 for the whole lot.
stripped 4, and brought home 5
3 dual cpu systems
they were disposing of a pile of dual CPU systems at work
so I got a lifetime supply of dual PIII's and dual athlons
I just need some pc100/133 512MB ram though.
ds3 that works =)
regular or registered?
not sure, I think regular.
(I'd have to look it up)
my boards had all registered memory :/
anyone need some PIII 550's?
I have a stack of 256, but need 512's to max out the mobo.
n/m i only have 128's
bummer, I'll probably toss a barter ad up on CL down the road.
even got a bunch of serial to LCD display modules and serial to EL display modules
ds3 Yeah? what kind/size? 2x16?
2x16 on the LCD; 4xsomething on the EL
I have one Indigo Blue EL 2x16 I was thinking of putting on the front end MythTV box
2x16 seem small
EL == Elctro Luminesant
the blue type?
alex_joni that purrty glow
HSC had some miniATX cases a while ago that have built in 2x16 backlit LCDs except I donno the pin out
oops.. maybe not EL... more like vaccumm flourescent (?)
let me double check which is which
this is EL http://www.gpegint.com/images/alpha/2x16.jpg
Oh... I have a ton of these and just a few vacuum displays
I need one in 2x40
alex_joni EL is kinda being repalced today with LED's instead as then they don't need the 10KV inverter
i like the vacuum displays
the led type
[21:04:50] <ds3> http://en.wikipedia.org/wiki/Vacuum_fluorescent_display
<--- got these in 4xsomething..maybe 4x20
ds3 Yeah, *I* think those are icky =)
i like them cuz they are brighter
Oh, I understand. They just have a fixed character display most of the time.

that's the problem with C

Nope, segfaults out if you select a line to draw. Just started trying it - got lots to learn :).
saw something on that, frugging AMAZING!
I need to watch again..
HEAVY ENVY :-)..........
Almost makes me want to toss the uMill in the trash :).
I could fit a 4th axis :D and 5th.. on my machine
but the work %"!
And expense :-/.
im so amazed at the contouring
And me still with an almost stock uMill :-(...
hm, I dont think it would be _that_ expensive
Yes, it was really ****amazing****!
my spindle is homebrew anyway
Heh, for me it would be.
Gonna be at LEAST 6 months before I get a 3 axis going :-/.
Still, a manual uMill is better than no mill at all, by a LOT :-).

Yeah, budget, looking at getting out of scabattle and out of apartment into a house.
K`zan: really now, get some busted HP inkjet printers and steal the servos out of them
I hate that machine
fenn is right
no need to wait 6 months to save money for something you dont need (geckos and oversized steppers)
and build the H bridges yourself
Not sure those would drive the umill, conventional wisdom says at VERY least 200 in/oz///
steppers are crap
and with enough gearing you can move anything
True, but gears ain't cheap either :-(.
you dont need speed for that kind of mill
you have a lathe..
and a mill.
what's keeping you from making gears?
yeah i've been meaning to hob some gears for a while now
Yes, just where to throw money is something I am being, perhaps too, worried about.
K`zan: 20DP is just a 20tpi tap used as a hob
fenn: I figure im going to machine gears someday
Not enough to shit away...
well, use plastic gears..
SWPadnos_ is now known as SWPadnos
dont use gears
Just replaced the crappy plastic crap in the mill with a belt drive :-).
fenn: do you think inkjet steppers will direct drive?
just use a different (better than stock) leadscrew
scabattle is not a place to find any kinds of bargains on this stuff, unlike chicago or atlanta.
though plastic is crap. :D
they come with timing belts and pulleys i think
I use 3:1 with similar size motors (maybe mine are a little bigger)
Yes, it is, gets expensive quick...
and a hassle.
At least I have reached the point where trying to make motor mounts doesn't send me screaming to look at the checkbook :).
ebay shipping will kill you :-(.
K`zan: well, why do you keep making excuses?
K`zan: either you do it or you dont, we are trying to give you the cheapest options..
maybe not the best, but the cheapest.
anonimasu: because A) I'm confused, B) I have a nasty budget and C) because I can ;-).
its easier to make excuses than visiting a copy machine repair shop
they are throwing one out right now K`zan

I really really want that machine.
look at that..
Problems here are traffic from hell (makes chicago look tame) and everything! is a long way from where I am, sigh. That is why we want OUT of here.

though that turbocharger housing one is the most impressive
it's as fast as thoose datrondynamics machines
the bar mill/turn doesnt look like its tall enough to swivel a full bar and not hit the floor
thoose seems to be surgical machines..
implants.. and stuff
[22:14:51] <anonimasu> http://video.google.com/videoplay?docid=-3550758284646677253&q=stama
96 seconds per part..
what a waste of titanium
the tooth implant
fenn: though you wont complain when your hips wear out from all the time standing next to your mill
but I think thoose are stainless..
looks like its cutting through cheese
said titanium at the end
50 hp spindles
Whew, that is just SO cool...
LOL, understand that :-)
how much of a bitch is titanium?
thoos machines costs more money then I'll own in my whole life
Probably less that a million dollars....
Yeah, too true :-(.
lerneaen_hydra: quite a bitch.. low thermal conductivity causes it to melt and stick to tool tips, and its pretty flexible (relatively low modulus)
hm, sharp tools and cooling?
how low is the modulus?
so it's similar to copper or shitty alu?
isnt all alu shitty?
At least the stuff from Lowe's and home depot...
wonderful to work with
actually 6061 cut's well, with sharp tools
Fortunately online metals is close :-).
or was that 6063
6063 is nice :D
6061 seems to work out OK here.
SWPadnos? it arrived, but they didn't ring my door bell... :( fackers.
or was it 6061-T6(maybe)
T6 is IMO good
lerneaen_hydra, want to be my moving target?
I cant remember the tempering
* lerneaen_hydra dodges
as in I get up at 6:20
and it's 11:20
lerneaen_hydra. wimp. but that's okay. :)
I wish the xylotex 1 axis driver was _way_ cheaper
need one more ef'ing drive
I wonder how impressed the GF would be if I made her a Ti ring...
eholmgren: why xylotex?
I was wondering that too...
eholmgren: thoose things have no midband resonance compensation :/
who else sells single axis drives?
xylotex: enjoy it... :) As long as you don't know what you're missing from a gecko. :)
... I have 2 centent CN0162's
eholmgren: or well, rutex.. or japan servo
anonimasu, no ... my member.
eholmgren: you really do want midband resonance compensation :) take my word for it
someone at the last party said they were hung like a gecko... I go... wait... the whole gecko, or just it's dick?
the girls got a chuckle out of that... :)
I wish the prices on IP-KVM's would hurry up and go down.
A-L-P-H-A: stop talking crap please
the centents do resonance comp
lerneaen_hydra: do you know where to get High density foam in sweden
no idea actually
lerneaen_hydra, got more picks of the waterblock you made... you still using that waterblock setup?
I'd love that kind of stuff for making molds of..
anonimasu: the blue/pink stuff?
not the stuff used for building
there's another kind of foam..
the blue stuff dosent end up with good finish
anonimasu, any styrofoam will work... acetone will disolve the styrofoam... the white pellet stuff.
spray on a "tooling gel" layer?
fenn: where do you find that in sweden?
hell if i know
still using it
and got more images
lerneaen_hydra, send them over...
anonimasu: if it were me i'd just use whatever resin i had and then buff it with paste wax
mall? all? or mail?
same address as you sent your resume from?
anonimasu: or if it's a one-off, put the styrofoam on the inside :)
lerneaen_hydra, dcc works too... but sure. where ever
fenn: works for cf..
though not fibreglass
it'll be big though
wait, I'll just host it
the resin eats the foam
oh.. use epoxy resin then
or polyester resin
well, then I might aswell do carbon fibre instad :D
polyester is what eats the foam..
have you checked CF prices lately? :)
what are you trying to cast?
fenn: I have a local supplier
* fenn guesses car parts
shit... Jymmmm sent me a link to this machinable wax company... that had epoxy casting resins... it was cool stuff.
they have good prices and I can buy in any sice I want
one liter resin and 50 meters of twill..
make a negative mould, and cast. looked like it worked great.

<-- don't download unless you want them, it's 50mb and my upload is slow
A-L-P-H-A: but that kind of stuff isnt avaiable here
anonimasu? couldn't they ship?
i want to do that with just regular gulf-wax stuff
A-L-P-H-A: from the usa?
also shipping costs lots of money :/

my geckodrive order is still missing

Your item was processed and left our SANTA ANA, CA 92799 facility on January 22, 2007. Information, if available, is updated every evening. Please check again later.
hm, I'm not a happy camper this time..
my mesa is sitting in the post office... I gotta pick it up... I'll pick it up tomorrow
Jan22nd, that's only yesterday
it's probably on a cargo plane.
I ordered before christmas..
oh. was Mariss on vacation?
then I changed my order for another drive, that they could ship faster....
are these servo drivers?
and then it still didnt show up at the post tracking until today
complain. and go get %20 off. :)
it's still shitty as I need the drives.
"Mariss, I would like to file a complaint against your shipping dept. I order blah blahb lahadsfasdf"
20% off dosent bring me drives faster.. :/
anonimasu, could have opted for over night express delivery for around $150USD.
