shrdlu-: are you using lots of short arcs/lines at high speed?
I'm trying to raster with the laser. scan the axis from one side to the other in one smooth motion
fire the laser at appropriate points
but it seems that either EMC, or my setup, will not allow two commands at the same time
which kinda means I've wasted a lot of time, money and screwed my clients over
sounds like it is time for a beer :)
* BigJohnT heads up to get some chow
I might melt my face off with the laser
are there any other gcodes that I can play with that will effect how smoothly two commands transition?
maybe I'm not blending it right
is the emc documentation done in open office?
raster using using arcs... huh?
I'm not using arcs
Well, HPGL is a vector language, not raster.
it contains both
but this isn't even properly featured hpgl. It uses PU and PD for switching the laser on and off, x and y as normal
and it's completely smooth
[00:38:43] <shrdlu-> http://www.youtube.com/watch?v=gnZ26ZAfo4c
I want to do that
mach3 seems to be doing it fine
maybe I'll have to buy that
wow, hm, that youtube link has pulled up a good looking raster to gcode prog
even if the program is in polish
if the feedrate affects using Z for the laser, would using a rotary axis instead fix that?
i dont really get why feedrate would make it pause
i mean you're hardly moving at all on Z in the first place, and Z should have ridiculous accel/velocity settings
and you did set [TRAJ] MAX_* to 9999999 right? (like i told you earlier)
everything is maxed out
could you post your hal and ini files on pastebin?
I've had to go into windows
why'd you "have to go into windows"?
so I can try mach3
I've been working with emc for 14 hour days for 3 days and I'm nowhere
all files are exactly how stepconf sets them up for a 3 axis machine
with high values for accel and velocity on the z axis
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-02-12.txt
hm, maybe I'll give it one last go with code generated via this converter
I would think to get the effect you want - z would have to be on its own line.
(I just jumped in again)
yep, that's true
even using the PWM mode, the laser power would ramp up/down over the course of the whole move
otherwise - it will change the power over the whole x movement.. (even though it is short)
it will still blend great though
I would think
you can also program ___/\___ instead of ____|_____
or _____|----- (sort of :) )
I've tried the z on its own line
can you draw a picture of a horse?
I think it was worse
are you running g64px.xxxx?
no (by hand or with ASCII art)
maybe I'm not using it right
I'm not sure it's what you want actually
you need the Z move to run, you don't want it to get optimized away by hte naive CAM algorithm
oh - good point
depends on how big the z move is..
that's big though, you want small moves so accel/vel limits aren't a problem ...
but not too small
or something :)
wow - I don't know the correct incatation.. how do you make a certain program open a certain file in ubuntu?
depends on the program I bet
I mean - I want to click on a sch file and have it open in eagle.
oh, right-click and you might get some option to "open with another program" or something
well - that is I think the other problem.. It isn't in the list and I can't type eagle from the command line. (I have to actually go to the program file)
there's an option to "use a custom command" at the bottom of the window
err, axis wont even load this raster code in decent time
how big is the file?
6.1 megs ;)
I've loaded a 20M file in ~30 seconds before
but that was on a fast PC :)
this is taking several minutes
you can press ESC if you don't mind missing out on the preview
what isn't working?
what speed is your CPU, and how much memory do you have?
3ghz P4, 2 gigs of ram
I don't know what's wrong there. esc definitely should stop the preview
ah, yes, it works. But not until half way through
it's running faster now I've killed off this prog in wine
that cannot be good. ;)

oh, i guess i should share with you guys too: http://fennetic.net/machines/hexegrity-applet/hexegrity.html
now that i think about it, X would have to stop to let Z move up and down
in the laser raster scenario
you really need synched analog i/o
I just typed in a moderately long g-code program and then realized that I need to rotate the part 90 degrees to fit it on the machine
does emc support scaling and rotation?
oh, well nvm then
it isn't as bad as it might have been - I put the profile in a subroutine and called it several times, so I only had to change it in one place
I also have to tweak entry and exit moves - the part _barely_ fits on the machine
that's a good feeling
"huh, i guess that DOES fit"
* JymmmEMC hands jmkasunich a machine stretcher
swap x & y cables?
= hardwire rotation
I fixed the program
in soviet russia, program fixes YOU
asking if its ok to move the limit switches is a good sign that you should upsize the machine tool one notch ;)
THREE HUNDRED NOTCHES
arghhh! cannot run emc in simulation mode
X Error of failed request: BadWindow (invalid Window parameter)
sounds familiar. are you trying to run over an ssh connection and forgot to connect with -X?
nope, fixed just now...
emerged xorg-server, and it stole my opengl...
put gl back to nvidia, and i got it to start fine
how does nvidia work with gentoo? i had some bad experiences with their custom installer
their = nvidia's
some versions work ok, others are unusable
as far as the gentoo part of it goes, never had a problem
besides the afore-mentioned fighting between packages over who wants to be the default opengl implementation
higher-performance, but less stable than ATI in my experience, but that is not comparing similar generations, so ymmv
anybody try to convert a grizzly g0484?
looks like an rf45 clone
just curious, because i have one, and plan to do said conversion
hard to find on google for some reason; here's the g0484: http://www.grizzly.com/products/9-x-32-Gear-Head-Mill-Drill-with-Stand/G0484
looks like a good candidate for CNC
will keep posted of progress
on peux parler français?
Savoir si le chan est anglophone ou pas :-)
tu peux parler francais, mais je ne comprend pas rien ;)
oki no prob (my english is very bad, but it's a good exercice for me ^^)
Stun2: seems good enough ;) better than my french
anybody have problems opening files?
as in emc crashes when opening a file, even clicking on a dir
Dr_Phreakenstein: what GUI?
no others even start up
Dr_Phreakenstein: start emc from a terminal (Applications->Accessories->Terminal)
and see what messages get printed in the terminal
alex_joni: thx, but, I have only english bases :-)
Dr_Phreakenstein: pastebin if it's more than 2-3 lines

btw, thanks for help
try to update CVS
there was a fix yesterday relaetd to segfaults
updated hours ago
again just now, compiling
I see you compiled and sudo make install'ed .. right?
it's always best to keep your local copy compiled for run-in-place
else you're overwriting an existing install
well, existing install is broken
what cvs command should i use?
cvs up -dP
using cvs -z5 -d:ext:firstname.lastname@example.org:/cvs co emc2
but before you compile, go to stc and (./configure --enable-run-in-place)
then make && sudo make setuid
np, exec'ing now
cvs -z5 -d:ext:email@example.com:/cvs up -dP
dumb question: how do i exec emc-environment
it complains and does not run manually
ahhh ... source it, don't run it
can any one help on IGBT driver circuit
i have difficulty time on buying the ic driver
Andy7: not sure if tight now, but maybe later (weekend) you get more answers
still segfaults on line 637
try a different sample config
alex_joni ok :)
i trying to use PWM on IGBT
Andy7: directly from the PC? or using an IGBT driver?
how fast IGBT could do switching, how low the Voltage it can transmit from Collector to Emmitor
Andy7: that's in the datasheet of the IGBT you are using
IGBT driver, home build one... no specific IGBT Driver, it is hard to find on local store
might be, but it only contain MAX VOLTage ...(300V-1200V) .. never LOWest Volt
sorry, power outage, telco rt lost power and reset
is 2Volt 500A would be able to? ...imagine Welder
2v, 500A?!!! that would take a lot of copper!
since the gate is 15V,25V,30V ...im not sure ...and the turn on/off timeing...
univpwm and univstep fail at line 340
yup, u bet
more amp more heat
ordinary igbt could handle 1200V 500A u know
gets bucket of liquid nitrogen
they alot on the local river
true, and cheaper
and ceramic to isolate
+ - ground of local river
any recomended, or particularly "
"safe " configs?
u should try one of these kind of welder... im not yet see forward on microwave welder...microwave= xx GHz ....IGBT only able to do 20KHz
just turn the igbt on and off, would do it
we would have best result if u add ferrite core transformer
everything still segfaults
* crams ferrite into computer as last resort
fans grind and throw chunks
only 5-axis config even starts, but segfaults at line 637 when i open a file
i must go, internet time limit is over for me, i must plug off, i wish u all luck.
thnx in advance
Dr_Phreakenstein: univpwm is using special hardware
you should be testing the sim/* configs
andy7 needs to download some books while he's online next time
or at least some datasheets
i am using 5-axis, but i have to load from command line...
i can reload using file -> recent files, so that will do
learning g-m code, so i have to keep reloading until i get a good plot
Dr_Phreakenstein: that is strange
yeah, no explanation i can guess
may be a tk thing, mged from brlcad was doing similar recently
that's not using Tk
Dr_Phreakenstein: when you type emc does the config picker come up?
usually, but i have been specifying config on command line
Dr_Phreakenstein: oh, ok.. so the configpickers works.. (that's also tcl/tk)
did you try mini and/or tkemc as a GUI?
try using configs/sim/tkemc.ini and sim/mini.ini
the 5axis also has vismach loaded which might be the culprit
will i get a pretty backplot?
what was the package that added wifi support to 8.0.4?
linux-ubuntu-modules-2.6.24-16-rtai I think
tomp: look for linux-ubuntu-modules and search for rtai
apt-cache search linux-ubuntu-modules | grep rtai
hmm, on a non ubuntu box now ( but it is on the net ) , and the grep returned nothing
i hope i can store it to thumb drive an move to the ubuntu system
you need to have the linuxcnc repository added in apt
so the apt-cache will probably return nothing
let me grab you a link
k, onto the wiki for them, thx
[12:37:49] <alex_joni> http://www.linuxcnc.org/hardy/dists/hardy/base/binary-i386/linux-ubuntu-modules-2.6.24-16-rtai_2.6.24-16.22.linuxcnc.2_i386.deb
that's assuming you have a i386 install
um, eeepc and xandros, i think its intel
I think you didn't install a 64bit distro
oh, wget was painless thx alex
urf! 'same version already installed', looks like i tried this already. need to do some research.
there is also http://www.linuxcnc.org/hardy/dists/hardy/base/binary-i386/linux-restricted-modules-2.6.24-16-rtai_220.127.116.11-16.34.linuxcnc.1_i386.deb
uh, dmesg & lspci doesnt even see the controller. ubuntu just doesnt see it 9 and it works fine under that other os
i get lotsa hits saying its an 802.11a+b/g wireless but noone says the chipset
seems to be a LiteOn WN630x PCI Express card inside the lappie
BigJohnT is now known as BJT-Work
BJT-Work: how are the utilities doing?
they are still trying to get everything hooked up.
many of the poles they set when the ground was frozen fell over when the ground thawed out because they didn't have time to set
at least where I live it is all rock but down south and east of here it is all sand and mud from the Mississippi
I'd have to guess that 90% have power back
aha. lshw -C network shows that the wireless chip is seen as eth0 and the r8169 river is loaded. isnt it supposwd to be ath0?
good evening.i want implementation the m fuction custom example m119 whith one parameter input.This parameter do write in pid.3.command for orientation the spindle. Is possible ?
back to annoy you all again
that cam.py has a very useful raster fill function, that will output 'raster' gcode
but I still don't like this stopping thing :/
good evening.i want implementation the m fuction custom example m119 whith one parameter input.This parameter do write in pid.3.command for orientation the spindle. Is possible write it?
ok thanks cradek.exist one manual for sintax the m code?
the m fuctionc after do write, is necessary compile?
motioncontrol: you can write a custom m code as any executable you like
even a compiled C file, or a shell script
ok alex, when i write in partprogram m119, emc control in nc_file directory the m119 and actualization the m119 script ?
if the m119 is a shell script, then you don't need to compile it
(there is an example included with emc2)

Hi, I got stuck on the pyvcp changes I'm doing and wrote down my toughts on the subject, maybe somebody could help me to find a nice way to solve the issues
[18:06:42] <JanVanGilsen> http://pastebin.com/m6b7c3d9
ok alex . i want write in pid.3.command : i write in m119 : halcmd setp pid.3.commad = in1 , in1 is input variable the position command. is ok for you?
setp pid.3.command $P
then M119 P10
that will cause setp pid.3.command 10
ok thanks alex this fuction i command the spindle in c axis mode
good evening.One quetion.in g33 z-10 k1 code when the z axis stay at -10 the spindle change direction itself or i write after m3 s1000,g33 z-10 k1, m4 s100, g33 z0 k1, etc?
you do not program the spindle reversal, it is part of the cycle
ok thanks cradek i use only g33.1 and spindle reverse itself, i don't use g33 for compenmsate tapping
sorry, I don't understand what you mean
i don't use g33 fuction , i use the g33.1 and fuction ok
right, g33.1 is the tap cycle
excuse cradek the canned cycle fuction in emc? example g84
please try to answer questions using the documentation first: http://www.linuxcnc.org/docs/html/gcode_main.html
ok thanks cradek
Somebody who has comments on my pvcp xml toughts?
oilproof pendant? http://west.loadup.com/military/surplus/12649.html
I'm sure it's waterproof, but it may not be oilproof
I like the large flat lid
cradek: way easier to work with than the tall & narrow US-style ammo cans
SWPadnos: fill it with water, then it's oilproof
