while looking for hints on autocad under vmware under linux... ( slow ) i came across BricsCad 'acad clone', but its 'for redhat 9, fedora 1,2,3', what kinda probs am i in for? ;)
using alien, i suppose
other than that.. ?
hunting down some dependencies
didnt think of alien, dloaded the tgz, yep expect dep hell
they don't have a list of deps?
cool ... "Delivered as RPM and as tar(for Debian-Ubuntu)"
deps? i will find out ;)
the only reason i would suggest finding a text list is because, from using slackware for a couple years, missing deps can sometimes be misleading in error messages
eh, it runs under wine, a zillion blah.dll.so files ( weird it runs under wine but is touted as a linux version )
and the user manual has a pdf icon but is an exe file :(
its help if you get it to run ( catch 22 )
that isn't sketchy at all, no sir
the tarball does have ahelp dir, and pdfs inside that. it seems it has sketch, dunno if its got the MDT extrude tho... i will keep trying
re bricscad. it opens sample 3d stuff ok, but none (of a dozen + files ) of mine showed any 3d content, only 2d renderings (aka layouts in acadese )
you install wine, you install brciscad, they send you a 30 day key, you run a script ( NOT wine icad blah ). very very very mdt like ( so far )
i seem to recall hearing ProE was available for linux
i love pro/e but I have very little experience with it
imho it's way better than solidworks, but it's more difficult to use
like emacs or vim vs. ms notepad
how can something that is more difficult to use be better?
its got a page in the pdfs, that compare the 3 versions, Linux, free W$ & w$ Pro... the linux column of full of 'not available' except for one 'partially available'
wasted a couple hours on that. maybe ubu hardy (no rt emc ) under vmware under w$ is easier, then i'd have acad native.
eric_unterhausen it's far more powerful
again, i point you to vim vs. ms notepad
solidworks makes a whole bunch of assumptions of things you will not try to do
fillets, drawing on surfaces, etc
and what actually makes pro/e difficult to use is it assumes you're going to want to do certain things, complex things, and that makes it more difficult to use if you aren't expecting it
like pulling data, relations, and geometry from elsewhere in the model into the current sketch
it doesn't just bring up the sketch view, it brings up all these dialouges and whatnot related to importing things
the first college I went to taught pro/e, it was too much for people who had never seen solid modeling before, but it was awesome
it would do absolutely anything you asked it to, as long as you knew how to ask it
the same can't be said of solidworks and similar packages, they just won't do everything
my productivity is much lower with pro/e
but I don't do advanced stuff
that's not been my experience, but I guess different people work differently
the only reason I wanted to use pro/e was for the cam post, but it turns out that mastercam loves solidworks files
and I wasn't smart enough to get the pro/e cam package to work anyway
i messed around with the cam package and it was really cool, but I wasn't into machining at that point
hmm, got acad mdt running under vmware, but on old laptop ( how'd i did i do that !! ;)
i can spin 3d models as well as native w2k pro

skunkworks: thanks for the heads up on cnc-toolkit
It's always been available, it's just that skunkworks has no life and just trolls cnczone for juicy gossip as he's such a drama queen!
good morning Jymmm

I'm trying to install rtai on a smp kernel
I ran the configure -r
so it sees the new kernel, then it says to do a debuild, what is that for?
trav: be a bit more specific
did you finish building the rtai-patched kernel?
is it installed?
I'm following these instructions http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC_With_Custom_Kernel
do the tests run?
and emc2 says it requires the real-time kernel 2.6.24-16-rtai
but I have an intel atom 330, so I was wanting the smp support
trav: try to go a bit slower
so I created the kernel 2.6.24-16-rtaismp
when you say "emc2 says" -> that is no real information
which I'm running currently
ok, so you're booted using 2.6.24-16-rtaismp, that is ok
next you want to either install the emc2 package (one that works with 2.6.24-16-rtaismp) or build your own
gpg: WARNING: unsafe ownership on configuration file `/home/travis/.gnupg/gpg.conf'
gpg: skipped "Jeff Epler <email@example.com>": secret key not available
gpg: [stdin]: clearsign failed: secret key not available
debsign: gpg error occurred! Aborting....
debuild: fatal error at line 1174:
yes I assume I'm trying to build emc2 per that web page instructions
I get to the debuild part and get that error
that is ok
it only means you couldn't sign the package
so just install the deb file and reboot?
no need for reboot either
ahh it worked
I see errors and I worry about them
alex_joni, can i pick your brain for a second
in the robot kine
do you know what A3 is ?
from what iv worked out A2 is link 1 of arm, D3 is the offset to the side of the base, and D4 is link 2 of arm
A3 seems to be the smallest of the offsets
so could it be wrist ?
did you read about DH?
its hard to get my head around what means what tho
A & D are 2 offsets
A2 and D2 refer to the link between joint 1 and 2
A3 and D3 refer to the link between joint 2 and 3
its all very confusing
A is angle and D is translation ?
[15:27:58] <alex_joni> http://prt.fernuni-hagen.de/lehre/KURSE/PRT001/EXAMPLES/eqs2/index.html
A is distance between the rotations aka strut length
and D is the side deviation
thanks ill give that a read :)
been a long time since iv had to do maths like this
and even back then i wasnt that good lol
you can see A & D here: http://uwf.edu/ria/robotics/robotdraw/DH_parm.htm
A3 is confusing because it looks like that joint is on the centerline
A3 should be the length of the second arm
but isnt that D4 ?
shorter than d4
but I think it depends how you select the coordinate systems centers
but as my bot has the joints on the centerline
d2 would be 0 ?
and would A3 be 0 aswell ?
[15:41:43] <alex_joni> http://www3.hi.is/~pgg/DenavitHartenberg.pdf
that's a pretty good introduction to 2 joints
SWPLinux: you ears must have been ringing
hmm im starting to think im in over my head slightly with this
SWPLinux: AVR uC's to TCP/IP modules (and chips)... http://www.saelig.com/miva/merchant.mvc?Screen=CTGY&Category_Code=MFR00088
(serious hint hint nudge nudge lol)
colin_: maybe there's a math univ. around your place
maybe i should just pay someone to write my kine
you use emc2 with robots?
im trying too
trav: Sure, why not?
guess I never thought of it that way, just seems it's geared toward cnc
you can use bots for cnc aswell
in fact thats why im doing it
trav: As example what's so different from a gantry router and a pick-and-place machine?
Just replace the spindle with a vacuum pickup
nothing, but when I think robot, I think articulating arm
Which is what, two maybe three motors
true tho, they all move in 3d space
all cnc machines move in 3D space =)
the idea of the kine module is to convert the 5/6 rotary axis of the articulating arm into linear xyz movements
colin_: have you looked at the pumakins or scarakins source code?
those two robot types are already implemented for EMC2
(of course, I've missed the rest of the discussion, so ignore me if I'm repeating someone :) )
SWPadnos, yeah of course
sadly I've worked for chrysler for many years with cnc's and robots
Here is an example http://www.youtube.com/watch?v=AoOWi1r6-Eo,

SWPadnos, just trying to work out what how the puma kins works
* Jymmm pokes SWPLinux with an gigabit hub
Jymmm: those look interesting. I'll have to check them out more when I have time
SWPLinux: Cool, chips are as low as $4, not too shabby, still need the xfmr though
and RJ45, etc
SWPLinux: Oh, and some of the AVR's already have (R/C) Servo too =)
alex_joni: what type of board is this? http://dsplabs.cs.upt.ro/~juve/emc/mytoy/HPIM5139.JPG
trav: Is this relevant? http://www.interfacebus.com/Design_Connector_PCAT.html
yes it's ISA, is just a motion control board?
A wild guess is that it is a single board computer, but I'm not qualified to say. Are there any markings or model numbers?
I never seen a SBC with an ISA slot, but ya never know
trav: an older SBC
at ~ 300MHz
you get ISA at the bottom, PC-104 and pC-104+ (PCI_
I got it for the 4 x serial
which I thought I needed 4-5 years ago :D

good night all
strange behaivour of hostmot2 stepgen
are you running installed or compiled EMC2?
home on index only does not work
ok. is the homing problem the problem with stepgen?
yes, home on index, axis wants to return where the move started...
Made a setup with parport -> runs fine, problem occurs using with hm2 stepgen
the stepgen has nothing to do with homing (or it's not supposed to anyway)
are you sure the index input was being correctly detected?
Yes, Hal-> watch -> index-enable -> gets FALSE
Problem is HM2 Stepgen, same Setup with Stepgen on Parport works fine
Seems to be the same problem that HM2 Stepgen had before 2.3.1, i've installed the 2.3.1 HM (HM Version did not change,right?)
Version 2.3.1 is 0.15 and 0.6 HM and HMPCI, is this the newest Hostmot?
where's fest news?
they must be having a lot of fun
