a-l-p-h-a, but be quick about it - I'm about to start playing Wolf:ET :)
* jmkasunich listens in
heh - I'm not hearing anything - you? :)
did I ever paste in the part numbers for the mating connectors (4-pin power and the mate-n-lock motor connectors)?
I think I did, and DK was out of stock but Mouser had some
you probably did, but pastes into IRC don't last
well, one more time: motor plug: 172340-1, Pin insert: 770988-3, 4-pin plug: 641127-4
all by AMP/Tyco
oh right - DK only sells those in reel quantity - 3000 at a time (but $0.25 each)
okay... looking for a digikey purchase...
dunno what I should be getting.
looking at wireterms.
and trying to figure out what I should go get.
break out boards, 50pin female headers...
ah. I don't think DK will be the place for breakout boards
and looking to see if there are any other toys I should be looking at...
SWPadnos, making my own breakout boards (BOB).
just gonna make a BOB, as I don't think $45 is a good idea, especially if I'm gonn have like 3.
well, do you want 50-pin cables to go from Mesa <-> breakout?
so you'd need headers then ...
make a BOB that plugs onto the Mesa card, and have terminal strips ...
yeah... not sure if I should be like buying 5rows of 10Wire terms... or look for like 25pin ones... of should I go for 2x24pins (as there are not 2x25).
even the DIN-rail 50-pin breakout boards use a bunch of bi-level 2x3 headers (plus a 2x2 at the end)
err - terminal strips, not pin headers ...
SWPadnos, what's the mesa manual page again?

I could get away with two 24 pin wire terms... and just not send out power/gnd on another break out pins elsewhere.
which would mean I just needed six 24pin connects, and a bunch of misc power/gnd connects for other toys elsewhere.
you'll probably get a better per-pin price if you get a higher quantity of a smaller terminal strip
like 25 6-pin or 50 3-pin
they attach together to make larger blocks
looking at Fig 1. http://dkc3.digikey.com/PDF/T071/0277.pdf
they do snap together... I have some 3 and 4pin ones here.
another thing to think about in making the BOBs is that you can group pins by function, and maybe use smaller terminal blocks for each "group"
like make an 8-pin encoder connector - Vcc, Gnd, and A/B/Z differnetial pairs
I have this as a break out board, currently... sec...

same guy... except mine's blue.
and you want to connect the Mesa card to that?
are all the isolation parts missing from that board, or is it just me?
SWPadnos, ALL, except liek 2 pins.
there's a hex invert that is connected to two pins.
that's not isolation, that's buffering
and I only see one component on that board that could be an IC anyway ...
ah yes - it is an IC - I see the pins now
but there are a lot of conponents missing from that board, so who knows
well... it's a 7404 IC, If I remember correctly.
they aren't isolated
ok. though that description says they are ...
"Completely opto-isolated to prevent any feedback or PC damage." bullshit.
thats what is known as "marketing" in the business world
in the real world its known as "lying"
anyway - my original question was - do you want to connect the mesa to that, or replace it with something else?
I want the mesa to connect to these things.
next question: why?
break out, easier connection to my gecko's later on.
but no isolation for your $200 mesa card ...
I'm looking to make an isolation board...
that other one, is my current setup.
ok, so you're planning on replacing that board with something that connects to the Mesa ...
but still provides terminal strips for your machine ...
well, it may sound counterintuitive, but I'd decide on what configuration you'll want to use the Mesa in, then design the breakout board9s) around that
the 5i20 is too flexible to design a breakout board for - or at least an economical one
it's a pain to make an isolated I/O board that lets you select the direction on a pin-by-pin basis, for example
okay... I'll hold off till I get stablized on a design.
good plan. you may be able to make a board that lets you relatively easily select I/O direction in 4 or 8-bit blocks
but I'd decide on how many motors, inputs, outputs, encoders, VFDs ... you want first
here's what I envision...
estop, limits, 4 axis stepper, spindle motor speed controller, various power relays
is that separate upper and lower limits for each axis?
any external buttons or lights?
:( so much
I want all the toys.
I have the basic ability to make it all!
count the I/Os, and see where you get :)
there are 72, so a lot of things can be done there
is that enough for a femme bot?
err - I don't know ...
maybe I should go make a pendant...
maybe I should go do some fragging :)
was thinking the pendant would go RS232 instead.
SWPadnos,... where you playing?
rs232 = harder to deal with
usually on HH servers
was gonna let EMC handle it.
why wolfET? there are other servers...
wolf:ET, not UT
err... other games.
because I have Wolf, and I like it
nono... there are other free FTPs out there, that kick butt.
wolfET is good... but I don't see enough maps
I understand, but I do like wolf
there are many that I play
hmm... maybe cause the servers I played on, didn't have them.
several MLB ones, a few others
I don't know if you've used the "no quarter" mod before - it's very good
I like the shitgun
I'll redownload wolfET.
don't forget the 2.60b patch
I like the HH servers: 184.108.40.206 or 220.127.116.11
[00:48:39] <SWPadnos> http://www.hh-ops.com/
oooh - looks like Alpha Base has 21 players on - time to go :)
omg... that site is using php-nuke. hahaha
can't get wolfET to load... official pak files not found...
no clue why...
a-l-p-h-a_ is now known as a-l-p-h-a
sourceforge news: 2007-02-12: The shell server was taken offline for unscheduled maintenance. We estimate the outage will last at least 24 hours.
I'm glad we barely have any services on sourceforge anymore
jmkasunich: I'm seeing something weird from stepgen when I change the maxaccel in a running system
jmkasunich: I have stepgen traking siggen 'sine' output. First I make maxaccel so large that it can easily track. Then I change maxaccel to be so low that it can't.
if it was near the peak velocity in one direction it (unsurprisingly) overshoots quite a bit. but then it overshoots GOING THE OTHER DIRECTION, which I did not expect

and in another halcmd change stepgen.1.maxaccel from 100 to 1
