clip9: didn't know it did! no idea...
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-08-22.txt
just looking for a little confirmation here... i just added a value to the backlash in the ini file, and the manual says i need to make sure my stepgen_maxvel is at least 1.5-2x my acceleration
I only need to do that for the axis i added the backlash value to, correct?
and my stepgen_maxvel value was 2.3, and my acceleration was 7.0, so now i need to make my stepgen_maxvel around 12-14?
ok - mental note. A). don't put anything plastic in the oven. B). check the oven before you turn it on for said plastic.

skunkworks: what did you stick in the oven?
the major thing was the plastic cutting board. I wasn't the dumbass that put it there.. I was the dumbass that didn't check. :)
oh, you mean a plastic chopping board?
oh well - let it all cool and it all popped off
I HATE when anything that melts/burns is placed in on around or near stove/oven
My gf is guilty of that, I keep ragging her about it too.
she won't do that anymore though.
what really sucked was the cutting knife that had a rubber handle.
our favorite knife
I don't think it was real rubber.. It didn't smell. no clue what it is.
wrap duct tape aorund it!
I whas thinking a nice wood insert - sealed up.
(match the kitchen) :)
Yeah, that'll give the NEXT piece of plastic you fabricte in the oven a nice smokey flavor
isnt EMC = Hardware company? :P
wrong emc - this is a cnc machine controller.

will comp preprocess a userspace comp file? I tried and the c file had the rtai stuff in it.
* cradek gently points mozmck to 'man comp'
thanks, but I already read it. here's what I ran: comp --preprocess --userspace ubob_outputs.comp
I tried it without the --userspace option and the output file was identical.
I don't know enough what I'm doing though. do I need something in the comp file to indicate that it is userspace?
oh hmm, sorry, I just figured you didn't know about --userspace
I need to make a userspace hal component, and I have a good bit of code in C so I'd rather not use python. This will be complicated enough that I don't think I can do it all in comp, but I figured I could start there and have comp generate an initial c file to get me started.
all I know I learned from reading the man page a few minutes ago :-)
heh, me too :)
do you know if there are any userspace components in c that I can look at?
looks like comp for userspace should be working as of 58e4f6e
there are a few in src/hal/user_comps, but no simple ones
ah, I'll look there. thanks!
surprisingly it looks like there are no userspace comps in git
is your checkout newer than 2009-07-11?
looks like that's when jeff fixed comp --userspace
I don't know when I first checked out, but I'm running master as of a day or two ago.
I have some comps under src/user_comps; gs2vfd.c, modbus.c
cradek: jr awake? ;)
looks like those may show me what I need. I probably don't know how to write a userspace .comp file
skunkworks_: yes! spindle is working.
skunkworks_: if I had a few more hours in the day, I would have cut something
finally, three working servo amps and one working spindle drive is a good feeling
did you mess with the servo amp I sent you?
no, I just put it on the shelf for spare parts. it is not quite the exact model, but it looks like the power parts are the same - a nice spare to have.
I see. yeah, spares are always nice!
the 1/8 tool holder is still soaking in penetrating oil - I haven't been able to get the set screw out yet.
I am patient and that oil is good stuff
I'd hate to strip out the hex in the teeny tiny set screw
oh wow, I didn't even try it. hope it comes out alright.
I bet it will
raise SystemExit, "Userspace components may not have functions"
that's in the comp code - maybe that's my problem..
I guess you need to have a loop that polls, like halui does
yeah, I need to read and write from/to the serial port
I'll make my loop run every 20 ms or so
seems like you'd want to use select for reading, and write if necessary when select periodically times out
* cradek checks to see whether that sentence was english - yep, more or less
yeah, man select
kind of a pain to use, but exactly what you want
no entry for select
"wait until there's something ready for reading on this file descriptor, or until the timeout expires"
I have to send a command before my hardware will talk.
oh it never speaks unless spoken to?
yep. I do a sort of multidrop or whatever it's called on standard serial
"manpages-dev" has select.2
does it ever say more than a few bytes at once? you might have to assemble the results of several reads if so
raw fd handling in C is such a pain
no, it's 3 bytes at a time 9600 baud.
cool, so they fit in the uart, and you'll probably get them all at once.
well goodnight, hope you get it.
thanks, and goodnight.
yes! finally got the proper screen resolution

dang I hate it when I do that
* jthornton and the wife are going on a ride on the couch with wheels
my tool lenght probe works ^^
is it possible, to modify the M06 command, that it does the probe automatic?
steve_stallings is now known as steves_logging
is there a reason to have a switch to ignore limits?
what do you mean a switch?
that bypasses the limit switches
if your limit switches are in your estop chain that can be very useful for jogging off a limit
my mill has that setup
you hold in the button, reset estop, jog off the switch, release the button
does your estop depower your drives?
that's the part I'm not sure of, I could just disable them
yeah it depends what failure you want to protect against
maybe I would like a bigger red switch that pulls a contactor
I think sometimes transistors fail by shorting out - nothing short of removing power helps you then
and my usual estop just disables everything
I'm no expert
I've seen shorted transistors
that should stop a brushless motor and fault the drive all by itself though
a brushed dc motor would go nuts
does anyone have an idea, how i will have go write an post prozessor for solidcam?
usually you start by adapting an existing one
start with Fanuc, emc2 is pretty close
i want to add, that it does allways a tool length probe after toolchange
then you look for M6 in the post
and add the code for the probe afterwards
where to find the post?
ok post found but how to modify?
it's text, isn't it?
pjm1, you about ?
building kicad from svn, fun
alex_joni what will i have to add in the post?
that's nice kicad build error
anyone know how to tell which boost library a routine is in? specifically BOOST_FOREACH
I have a question on tuning the servo driver. It says to use a +- square wave at 5 volts at .5hz. I am assuming that you disconnect the motor from the axis for this adjustment. any sdvice would be helpful.
apt-get has spoiled me, which is good
on the kicad developers list: "I knew this was going to happen"

python libs for cad
I hope all these warnings about missing string literals are no big deal
archivist yes i'm just back from the airshow
did you have a starturn?
um no i dont think so, what is that?
old denford cnc lathe
ah no, i am thinking of getting a lathe though, there is this emco one that i'm waiting to 'collect'
Im sure we had a brit with a starturn in here once... some appear for a few days and vanish
ahh that is a shame, we need more brits!
btw my mesa cards are in transit!! finally I'll have something that can keep up with my spindle encoder
by ballscrew arrived
need another and few more bits then attack the beast to get more travel
that's what she said
Man, they have some funky scissors
anybody know of something I have to do to get SVN working with the regular EMC Live CD install?
geo01005_home: sudo apt-get install subversion
also i think you'll need build-essential
hmm, I have done both of those things.
