jmkasunich: does easycad do polylines?
it does polygons
I'll boot it up and see if does polylines
I'm finally writing dxf-realize
easycad has "paths"
is that a polyline made of lines and arcs?
but they seem to consist only of lines, not lines and arcs
I fear dxf-realize is gonna have to do the sucktastic guessing of what things are supposed to be a path
searching for polyline in the help system finds spline only, the text is "CUBIC B-SPLINE (smooth polyline in AutoCAD® terms) draws an open smooth curve"
the sucktastic guessing takes it from being something simple to something not
well if this is going to work with (the free) qcad, I have to bite that bullet anyway
yes I agree
qcad doesn't have polylines either?
not the free version
and it doesn't have 3d (a polyline can't be at z=-1)
so that scheme is out the window too
I thought realize used layers for Z
no, that's also sucktastic
layers for *tools*
easycad doesn't do 3d either - fastcad does (thats the deluxe version)
I'm now remembering why I never started this
but, I remembered too late, as it's well-started
I was about to say don't feel like you have to start it on my account
it seems like it will be extremely hard to make it work right
very easy to have a badly behaved drawing, and no real way to check the result short of loading it into axis
the whole way it works is polylines are tool paths, and depths are depths, and layers are tools
without polylines and depths, you are in a bit of a pickle
nearly all of that has to be thrown out to work with these lesser cad programs
no offense, that's not how I meant to sound
seems like you aren't really talking about rewriting realize
we're talking about a different kind of cam program
I was thinking minor hacks might make it work, but it would have to be pretty much reamed
I'm thinking about a different structure completely
I could have it reading autocad's dxfs in an hour, but fat lot of good that does anyone
list of lines and arcs, mission is simply to make paths that include all of them
you mean unordered list right?
pick one line or arc arbitrarily, find another with its endpoint within some epsilon of the first one, continue till you run out of things within epsilon
yes that's what it would have to do
probably not even that hard
but where do you get depths?
well, for what I've been doing to date I don't need depths
but thats not a very general solution
if its 2d cad, you will have 2d paths
its the users job to set the depths - the program just removes the drugery of connecting lines and arcs, and calculating I and J values, etc
the epsilon algorithm would get confused if you had a t-junction anywhere
which makes sense, cause you can't machine that
which one is the toolpath, and which one is the mistake?
neither - they're both toolpaths
one is two segments, one is one segment
well, I don't see that making a meaningfull part
one or the other path will be cutting stuff thats already been cut
I cut a T-shaped path in max
it's true some of it was a recut
but if you want a T, you have to do that
you can't make a T surface in 2D
I'm not talking about a T-shaped slot
what are you talking about surface?
I'm talking about a T shaped surface
these are tool paths, not surfaces
all the realize things you did for me were paths that I used with radius comp, they were the actual part shapes
I got my microwave
telnetww is fast?
And just got a Ubuntu server setup to route to my local network.
got the bits marching in rows and columns now, instead of crawling up the anchor line?
Something like that.
Fast-air has a speedometer. Something around 2m is average though I've seen it near 3.
Any thoughts on the timeline for 2.3
have you pulled the photos off your camera yet?
sometime after 8.04 is released, I think
I want to see the one with max and the big rougher
jmkasunich: no, but I can
hmmm. I left the camera in the room
no wifi there, unfortunately
oh, you're on the road again?
is this the bollywood trip?
Sunny Mishicot, Wi
jmkasunich: were you involved with EMC when support for RTAI was first added?
(it llooks like RTLinux was first, then RTAI a year or two later)
when I started, there were lots and lots of compile time #ifdef, etc stuff to switch between support for different OSs
I've procrastinated a lot on getting that email out to the EMC movers and shakers
I got involved with RTAPI to get rid of that
yep, I'm seeing a lot of that
ok, RTAPI was around 2002 or so maybe?
there was even stuff in there for windows and windows CE
2003 I think, but I might be getting mixed up
yep, and whatever the DEC Alpha UNIX was at the time :)
my coding started after a meeting held a the NAMES show - not an emcfest or anything, just a meeting in a room
but I'm no longer sure which year it was
hmmm. was that the one where the board was first discussed?
no, that was at the emcfest in Ann Arbor (smithy)
at least one, maybe 2 years later
ohh, history: http://www.metalworking.net/EMC_news_history/Meeting2003.html
I've got half a dozen of those open :)
some from the defunct NIST site
it looks like RTAI was released some time after RTLinux, but I think before FSM Labs took it
(it being RLTinux)
I didn't realize that RTAI was a university project at the beginning (just like RTLinux)
judging from those meeting minutes, RTAPI started shortly after the 2003 NAMES show
that was the first coding I ever did for EMC
my first introduction to emc was at the 2002 names show, I met Jon Elson, Ray, and Paul there - over the next few months I started reading the mailing lists etc
cool. amazing how much happens in a few years, isn't it
[04:17:14] <jmkasunich> http://emc.sourceforge.net/NIST-archive/msg04097.html
fred, reporting that he set up an emc mailing list
it had 4 subscribers
hmmm. I Think I have an archive of that list traffic, but I'm not sure how far back it goes
I think this is all of it: http://emc.sourceforge.net/NIST-archive/threads.html
the emc-users list was created shortly after that 2003 meeting, IIRC, and thats when we phased out the list at nist
strange - I think I got involved in 2003 or 2004
2004, must have been
the first fest I went to was 2005, at NIST

HAL rev 0.01 ;-)
heh. I'm just reading through a long message from Ray on how to go about developing HAL (new CVS module, etc)
heh - funny that you mention the G2002 in that post
damn, somehow it went from 10:00 to 11:30 in five minutes
the dog must be ready to explode by now
wasn't your fault
oh, he's not driven by bodily functions - took care of those a bit ago
he's driven by the urge to sniff every tree, bush, leaf, and snowflake in the neighborhood
most of them twice
must get a cold nose this time of year
he seems immune to cold tho
earlier I had him out back, where the snow is chest deep
he'd run two steps, then plunge his entire head into the snow to sniff something
a few seconds later he'd snort, come up for air, run two steps, and plunge the head in again
up to his hears in the snow
ok, this time I'm really off
if you need translation services, ping me ;)
hey neat it actually works too
emc is a little too picky about its arc endpoints :\
alex_jon1 is now known as alex_joni
cradek: seen the dxf2gcode ?
I haven't run it, but I looked briefly at the code
if it's good, we should try to get the guy to help us set it up for distribution with emc
afaik it already works as an AXIS filter
we should look at packaging it for the LiveCD
how's the microwave?
I'm getting the network worked around to what I want
