this is nice but the P=0 and external command + output sum is goofy
I wish there was a way to associate the wiki editor with the irc user (if he's here)
the other day - flyingelectron was on #emc
people could jsut use their IRC names
[15:42:09] <skunkworks_> http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-04-11.txt
started out as guest3673456
cool, maybe he will come back.
I think P=1 and removing the external sum would give him the same result and be much more standard
and of course, give adjustable P gain so it can be tuned
I=D=1 seems strange as well
er, no, P term is ~ error, not command
so it wouldn't give him the same behavior
but anyway, it sounds like the stability is not good currently
maybe I should try doing that again, now that mesa has index-safe velocity
when index was enabled - it would reset the velocity also?
sometimes I'd like to be able to change my varispeed (drilling large holes)
skunkworks_: I was using ddt on counts to get velocity - when counts reset, the ddt would go nuts for a cycle
it seems that FF0=1 (or FF1=1) would eliminate the need for the sum2
yes FF0, I think
in fact, I'd bet that results would be better with FF0=1, I=(something, maybe 1), and P=D=0
but at least all the parameters would be usable
newegg seems down. where else can I order a name brand micro SD and know I'll get it?
newegg isn't down for me though
micro SD are way too small
wtf, $9 for a gigabyte with two adapters?
is sandisk still decent?
hmm, they're out of the adapterized ones
they had these things on sale at Costco until last Monday

what are you adapterizing it to?
hah. 2GB are less expensive than 1GB
wow. and 4GB are the same price as 1GB

it would be nice if it had the CF thing with it - not sure I can plug anything else into the reader on my computer
CF or SD?
CF for the computer, micro SD for the phone
I wonder if I've seen uSD to CF adapters
it doesn't say SDHC so I think I need to stick with the 2GB card
might need to use two adapters...
check your computer. I think I have extra sets of the mini-SD / SD adapters I can send you
I also got a neat USB adapter - it's the size of a USB plug
I can't believe how cheap this stuff is.
I'm pretty happy with the 8GB CF "hard disks" I put in two of my laptops.
[15:59:29] <SWPadnos> http://www.newegg.com/Product/Product.aspx?Item=N82E16820134855
newegg still isn't loading for me
that USB adapter is a bit big
[16:01:51] <SWPadnos> http://www.shopping.com/xPO-Kingston-Kingston-KW-B042G-1MAQ-2GB-MicroSD-Card
$9.99 with free shipping at NewEgg (once you can get to it again)
sure (if you can get to it :) )
hmmm. should I get a netbook so I don't have to lug the big laptop on a cruise ??
what a first-world problem that is
I have a usb thumbdrive that takes my micro sd chip. Works great
same here, only it's pinky-sized
last pinky joint sized even :)
gotta love trade show schwag
got a tiny bluetooth adapter also, so small it'
it's hard to remove
the really nice thing is that there was a 2GB uSD card in the reader too :)
I have a thumbdrive-sized 3G modem, which takes a micro SD too
this is the one I got with my Beagleboard: http://www.iogear.com/product/GBU421/
it's mighty tiny
I've seen a wireless mouse adapter that was a bit smaller :)
and the USB connector is a tight fit, since it's meant to stay in the jack all the time (not too useful when you fly a lot though, especially if your laptop already has BT inside :) )
I'm sure they can stick everything inside the connector, but then you can't remove it
also. the metal around it makes a poor antenna design :D
a great Farraday cage though
it might be necessary/desirable to have a little bit protruding beyond the cage
hmmm. I wonder if 512M was enough for the rewritable filesystem on my bootabler Jaunty USB stick
SWPadnos_ is now known as SWPadnos
SWPadnos: get a pair of myvu crystal video glasses and hook them to your beagleboard, no netbook needed
the shopbot people have opened their toolpath language and are presenting it as an alternative to G-code
[19:16:31] <seb_kuzminsky> http://blog.makezine.com/archive/2009/04/shopbot_open-sources_their_code.html?CMP=OTC-0D6B48984890
what does opensbp have over g-code?
did you hear back from that guy about how he was jogging?
seb_kuzminsky: not yet, but I think keyboard
istr there's a known problem with keyboard jogging - it doesnt always register key-up events when it ought
but like i said in the email, halscope will show what's going on
I doubt that would cause such an issue
the only explanation I have is that the free planner uses a different accel/vel limit
on a related note - is it possible to script halscope? set pins to monitor, set trigger conditions, let it run, then dump the data to a file for later analysis?
I think you can use halstreamer for that
oh yeah! cool!
although hal_streamer has the disadvantage you can't feed more than one thingie at once
so you'd have to use more than one streamer
which means sync-ing them will be a PITA
when you say "it overshoots", do you know if he means "position-cmd goes to X, but position-fb goes past X to X+epsilon, then goes back to X", or does he mean "position-fb goes to position-cmd, but position-cmd goes past where I want it"?
he means the motor
it moves to a certain location, then moves back
like it corrects itself
(couldn't brake hard enough, or something like that)
I asked for a halscope trace
jogs happen "below" the trajectory planner, right? they're joint motions, not axis motions?
err.. that's a, confusing to answer, quesiton
but yes.. :)
there is a separate planner, called the "free" planner
which does simple trapezoidal control of each joint
(the requests are actually for axis jogs, but hte planner does joint jogs, but that's ok since he's using trivkins) - as a sidenote :D
does it connect to the axis.X.position-cmd nets?
i'm getting confused...
outside of emc's motion controller nothing changes
same position-cmd and -fb are used
the selection between the "free" planner and the normal trajectory planner is not done via HAL, it's done inside emcmot?
based on the current motion controller mode
when jogging the motion controller is in free mode (also used for homing)
and the "fp" is subject to all the same vel & accel constraints as the normal tp?
when under normal control (MDI, program) the motion controller is in coord. mode
it _should_ :)
the limits get set using the same mechanism
SET_FOO which sets both the free limits, and the TP limis
then there's also teleop mode (for coordinated in axis space for nontrivkins machines)
alex_joni: do you know about how far it overshoots?
