[01:13:11] <Gamma-X> got wire strippers and a multi meter.
[01:30:02] <Gamma-X> anyone available that has a mesa i got the proper tools and talked to someone about the anilam circutry.
[01:45:05] <Gamma-X> ?
[01:57:12] <Gamma-X> no one is on...
[02:42:39] <lewin1> lewin1 is now known as lewing
[02:56:59] <Gamma-X> anyone alive?
[03:09:42] <toastydeath> rrr
[03:09:43] <toastydeath> er
[03:09:44] <toastydeath> ffff
[03:17:38] <Gamma-X> GO BIG BLUE!
[04:38:50] <eric_U> Gamma-X what did you find?
[05:25:30] <alpha1125> alpha1125 is now known as a-l-p-h-a
[07:13:29] <SkinnypuppY34> brrrrrrrrrrrr
[08:20:12] <lerman__> lerman__ is now known as lerman
[10:23:04] <micges> alex_joni: have minute ?
[10:25:18] <alex_joni> yes
[10:27:24] <micges> ploter.ini file
[10:28:15] <micges> in TRAJ section default speed and acc are about hal or so max_vel and max_acc value
[10:28:22] <micges> half*
[10:28:52] <micges> in TRAJ section default speed and acc are about half or so max_vel and max_acc value
[10:29:07] <micges> why ?
[10:30:00] <alex_joni> I'm not sure what ploter.ini is
[10:30:13] <alex_joni> but default speed and acc are mainly used for jogging
[10:30:37] <alex_joni> (read by the GUI as the initial jog speeds)
[10:30:48] <alex_joni> other than that I don't think it's used anywhere
[10:31:10] <micges> ok I check it
[10:31:13] <micges> one more
[10:31:55] <micges> In [AXIS_n] section speed and acc suppose to be eqal to values in TRAJ section or not ?
[10:32:00] <alex_joni> no
[10:32:17] <alex_joni> in each AXIS_n you set the max speeds for the individual axes
[10:32:34] <alex_joni> the TRAJ refers to the tooltip (e.g. G0 moves)
[10:33:06] <alex_joni> if the move is in XYZ (x0y0z0 -> x10y10z10) the move can be done with faster speed than the speed on X|Y|Z
[10:33:41] <micges> and when TRAJ values are smaller than AXIS_n section the following error occurs ?
[10:34:13] <micges> then axis is to slow to follow trajectory ?
[10:47:57] <alex_joni> no, it shouldn't give a following error
[10:48:01] <alex_joni> it will go slower though
[10:48:13] <alex_joni> the trajectory planner will limit on (traj and axis_*)
[10:48:25] <alex_joni> so if axis_0 has 100mm/sec
[10:48:29] <alex_joni> and traj has 10 mm/sec
[10:48:40] <alex_joni> you can't move axis_0 faster then 10mm/sec
[11:16:47] <archivist> ew probotix looks cheap, I wonder how good
[11:35:13] <alex_joni> archivist: http://www.xendoll.com/
[11:35:32] <alex_joni> City.Guangdong Province,China
[11:35:53] <archivist> gah flash horror
[11:36:00] <alex_joni> (hint: skip)
[11:36:38] <archivist> acually was looking at his steppers and drivers not that little "thing"
[11:41:28] <archivist> I think retro fitting real industrial machines gets better bang for the pound
[11:41:35] <alex_joni> archivist: looks like a sherline clone
[11:41:56] <alex_joni> and they also have some unimat clones
[11:42:09] <archivist> far too light weight for reall work
[12:57:32] <alex_joni> archivist: depends what you call real work
[12:57:49] <alex_joni> if it involves wax or soft plastics.. I see no reason why it would be too light weight :D
[12:58:22] <archivist> cutting steel with a 10mm cutter
[12:59:13] <archivist> I like a bit of power and rigidity
[13:01:08] <archivist> I remember trying a Sherline at a Medel Engineer Exhibition some years ago and was impressed (about 5mm end mill in it)
[13:26:21] <Guest674> greeting all
[13:27:57] <skunkworks_> logger_emc: bookmard
[13:27:57] <skunkworks_> I'm logging. I don't understand 'bookmard', skunkworks_. Try /msg logger_emc help
[13:28:00] <skunkworks_> logger_emc: bookmark
[13:28:00] <skunkworks_> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-01-21.txt
[13:29:22] <fogl2> i am looking for the source code of hal pid module. I am searching the cvs but i cant find it. Can someone please direct me where to search.
[13:30:55] <jepler> fogl2: just a moment, I'll find you a link
[13:31:06] <jepler> if you have the source tree, it's emc2/src/hal/components/pid.c or pid.comp
[13:31:40] <jepler> if you want to view the source and history online, it's http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/src/hal/components/pid.c?graph=1
[13:32:49] <skunkworks_> Good morning
[13:32:53] <jepler> hi skunkworks_
[13:33:21] <skunkworks_> Still winter here :)
[13:35:40] <jepler> here too
[13:42:48] <fogl2> thank you jepler
[13:46:34] <skunkworks_> jepler: Did we find out if xemed(sp) got his pwm+dir working?
[13:46:41] <skunkworks_> out of the pluto
[13:47:29] <jepler> skunkworks_: he wrote me and said he didn't think the change worked.
[13:47:38] <jepler> skunkworks_: so it's waiting on me to take the time to hook up my pluto again
[13:47:50] <jepler> but that never seems to happen when I'm at home
[13:47:52] <jepler> must be a bug in me
[13:48:48] <skunkworks_> heh
[15:00:22] <Gamma-X> anyone on? im tryin to hook up my cables to the mesa cards anyone can help?
[15:16:46] <skunkworks_> SWPLinux: !
[15:16:52] <skunkworks_> how is california
[15:17:22] <Gamma-X> hey skunkworks u got mesa cards? i forget. im trying to hook them up now. the servo wires atleast...
[15:17:37] <skunkworks_> I do - but have not done anything with it. sorry.
[15:17:48] <Gamma-X> damn...
[15:18:05] <Gamma-X> u wouldnt know wich terminals on the 7i33 get the servos do u?
[15:18:17] <Gamma-X> or got any info on that besides the crappy mesa manual
[15:18:34] <SWPLinux> it's annoying at the moment
[15:18:38] <skunkworks_> heh. no
[15:18:58] <Gamma-X> SWPadnos are u kickin it up in compton?
[15:19:12] <jepler> http://mesanet.com/pdf/motion/7i33man.pdf page 5 is the only reference I know of
[15:19:27] <Gamma-X> jepler that manual is horribal
[15:19:54] <seb_kuzminsky> the pinouts on page 5 look pretty good to me
[15:20:08] <jepler> 0, 1, 2, 3 are the different channels
[15:20:17] <jepler> AOUT is the analog voltage output
[15:20:19] <Gamma-X> well it dont tell u what /x0 and x0 are used for
[15:20:25] <jepler> ENCA, ENCB are quadrature signals
[15:20:34] <jepler> IDX is the index signal (optional)
[15:20:48] <Gamma-X> im gettin schooled yay! thanks jepler
[15:21:02] <jepler> ENA is an amplifier enable (I think)
[15:21:06] <seb_kuzminsky> The idx and /idx pins mean the signals are differential
[15:21:46] <skunkworks_> you could look at this config also - to get ideas http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/m5i20/
[15:21:48] <jepler> right -- if you don't have a differential encoder then leave the /idx and /encab pins unconnected and leave the corresponding jumper W1..4 in the "TTL" position
[15:21:58] <jepler> if you have a differential encoder then connect both and modify the W1..4 jumpers
[15:22:17] <Gamma-X> im goin to try and use my scales..
[15:22:26] <Gamma-X> anilam series 2 haha!
[15:23:13] <fretless85> hello
[15:23:18] <jepler> hi fretless85
[15:23:33] <Gamma-X> hello fretless85
[15:23:36] <fretless85> how is it going?
[15:23:55] <Gamma-X> tryin to hook up my cables to the mesa cards
[15:24:27] <fretless85> mesa? servo driver?
[15:24:40] <Gamma-X> yup
[15:25:09] <Gamma-X> 7i33
[15:25:13] <fretless85> i will use UHU i got some for cheap
[15:25:22] <Gamma-X> cool
[15:25:48] <fretless85> 3 pieces for 80€
[15:26:05] <Gamma-X> idk what that symbol is but 80 sounds cheap lol
[15:26:15] <fretless85> euro
[15:27:11] <fretless85> thats about 115$
[15:27:36] <Gamma-X> jepler what is the e0 for?, and correct me if im wrong x0-x3 are my servo sigs correct?
[15:28:41] <jepler> Gamma-X: which 7i33 pin number do you mean?
[15:30:24] <Gamma-X> uhhh wow i got confused one sec
[15:30:54] <Gamma-X> if ur holdiong the 7i33 in ur hand and the weidmuller connectors are to the right doese it go pin one from the top or bottom
[15:32:20] <Gamma-X> or i could just ask this, on the 7i33t it says dro and ground, those are my servo analog out signals right?
[15:32:54] <jepler> look for a silkscreen "pin 1". Page 3 of the pdf manual shows that "pin 1" is on the bottom when the servo amp connection is on the right, but I think that's for the IDC version.
[15:33:15] <jepler> I don't see a silkscreen "dro" anywhere
[15:33:15] <Gamma-X> i c
[15:33:18] <Gamma-X> i got it
[15:33:36] <Gamma-X> its right next to the pins
[15:37:57] <jepler> "This page intentionally almost blank"
[15:38:02] <jepler> I chuckle every time I read that in a mesa manual
[15:39:09] <SWPLinux> yeah - I liked that
[15:39:25] <Gamma-X> signal of servo goes to pin 10
[15:39:31] <Gamma-X> for servo x
[15:39:47] <Gamma-X> correct?
[15:42:33] <Gamma-X> ?
[15:42:38] <Gamma-X> jepler?
[15:42:51] <SWPLinux> Gamma-X: nobody knows - read the manual :)
[15:43:02] <SWPLinux> (that's what we'd do to answer the question)
[15:43:41] <Gamma-X> SWPLinux its so vague! lol
[15:43:49] <Gamma-X> im gunna fuk this up hahah i already know it
[15:43:54] <SWPLinux> cool!
[15:44:14] <archivist> or its up to you to decide
[15:44:58] <SWPLinux> Gamma-X: to answer your question, I'm stuck at San Jose airport for a couple of hours, after getting 3 hours sleep and arriving about 2 minutes late to check in for my scheduled flight
[15:45:29] <SWPLinux> so now I get to fly to LAX, then Washington DC, then home to Vermont, but I get to arrive at close to midnight instead of 6:25PM
[15:46:04] <Gamma-X> damn!
[15:46:10] <SWPLinux> at least I get to (a) use my free t-mobile account (wifi on Ubuntu), and (b) see how long the battery in this laptop actually lasts
[15:46:36] <Gamma-X> SWPadnos theres electrical sockets there...
[15:46:38] <Gamma-X> look around
[15:47:00] <SWPLinux> none near the coffee shop/wifi spot - O'll look elsewhere when prompted :)
[15:47:05] <SWPLinux> I'll
[15:47:49] <Gamma-X> hahaha. ok . I was stuck at dubai airport and sat in the irish restaraunt eating sausage links plugged into the wall.
[15:47:54] <SWPLinux> heh
[15:47:59] <Gamma-X> on my pc hahaha
[15:48:05] <SWPLinux> electric sausages, weird :)
[15:48:17] <Gamma-X> ehh i forgot a comma
[15:49:02] <SWPLinux> so, Jymm and I used this place over the weekend: http://techshop.ws/
[15:49:07] <SWPLinux> it's a pretty cool place
[15:51:10] <SWPLinux> maybe I'll unplug this damned ATM that's bleeping every 5 seconds
[15:52:10] <archivist> that looks a wonderful place to play at
[15:52:41] <SWPLinux> yeah - they've got a *lot* of different kinds of equipment
[15:52:49] <archivist> almost every toy a boy wants
[15:52:52] <SWPLinux> heh
[15:53:18] <SWPLinux> the powder-coating/anodizing room was a surprise
[15:53:23] <archivist> wasnt expecting electrinics as well!
[15:53:38] <SWPLinux> yeah, though the test equipment is a generation or two old
[15:53:46] <SWPLinux> may still work - didn't check
[15:54:07] <archivist> old stuff works if you know how to drive it
[15:54:21] <SWPLinux> that's the one problem - once you take the safety course, you can use the milling machines, but that doesn't mean you really know what you're doing
[15:54:36] <SWPLinux> so the machines are fairly beaten up, though they still work
[15:55:32] <SWPLinux> I think I had manual toolchages down to around 30 seconds toward midnight last night :)
[15:55:45] <Gamma-X> just talked to anilam again they gave me the pinout for the scales.
[15:55:54] <archivist> we sometimes allow people here to cut their own gears
[15:56:10] <Gamma-X> a a channel
[15:56:10] <Gamma-X> b b channel
[15:56:10] <Gamma-X> c plus 5
[15:56:10] <Gamma-X> d common
[15:56:10] <Gamma-X> e open - earth ground
[15:56:11] <Gamma-X> f marker pulse.
[15:56:13] <Gamma-X> half thouysandts 10 micro,
[15:56:15] <Gamma-X> quadrature ttl output
[15:57:04] <SWPLinux> is "marker pulse" equivalent to index?
[15:57:16] <Gamma-X> pretty much
[15:57:20] <SWPLinux> cool
[15:57:46] <Gamma-X> the resolution is 10 microns.
[15:57:49] <Gamma-X> that sounds good?
[15:58:02] <SWPLinux> scales are pretty cool - the machines at techshop had scales and DROs
[15:58:18] <SWPLinux> yeah, 10 microns is OK - something like 1/4000 inch I think
[15:58:25] <SWPLinux> or maybe 1/40000
[15:58:42] <Gamma-X> half thousandth
[15:59:01] <SWPLinux> hmmm
[15:59:12] <SWPLinux> should be a quarter thousandth, no?
[15:59:36] <SWPLinux> no
[15:59:38] <SWPLinux> :)
[15:59:39] <Gamma-X> well the dude at anilam seemed verry confident on the subject
[15:59:56] <SWPLinux> a 2.5th or a thousandth ;) (0.393701 mils)
[16:00:00] <SWPLinux> s/or/of/
[16:00:11] <SWPLinux> yeah, it is close to 1/2
[16:00:36] <SWPLinux> that's not great for dynamic positioning
[16:00:50] <Gamma-X> question.... on the mesas there are 9 wires terminals on my scales theres only 6...
[16:01:01] <Gamma-X> and one of them is an earth ground but im sure i can use the ground on the mesa
[16:01:36] <SWPLinux> I think you don't need to connect the earth ground to the mesa
[16:01:42] <SWPLinux> common is signal ground
[16:01:46] <SWPLinux> (pin d)
[16:01:47] <Gamma-X> would I use the / terminals
[16:01:59] <SWPLinux> I'm not sure
[16:02:17] <SWPLinux> you can jumper the mesa to be single-ended, in that mode, you may not need to connect the / lines
[16:03:36] <Gamma-X> well if i jumper it i dont think i can use the ttl or sumtin right?
[16:03:50] <SWPLinux> that's kind of a vague question
[16:04:03] <Gamma-X> im a vague person
[16:04:12] <SWPLinux> then the answer is maybe
[16:04:18] <Gamma-X> hahaha
[16:04:25] <Gamma-X> ok
[16:06:49] <cradek> surprising that you don't have differential outputs on the scales
[16:08:27] <Gamma-X> cradek there from 1989
[16:08:59] <cradek> my machine is from 83 and has differential
[16:09:04] <SWPLinux> differential signaling has been around for a long time
[16:09:38] <SWPLinux> (actually all voltage signals are differential, but that's a different story)
[16:10:20] <Gamma-X> lol wow
[16:18:06] <SWPLinux> OK, time to try to find an outlet - let's see how power management works on this beast
[16:20:27] <alex_joni> SWPLinux: lol
[16:26:09] <skunkworks_> well - he hasn't logged out yet..
[16:26:12] <skunkworks_> ;)
[16:27:25] <Gamma-X> question.... Can any of the grounds on the mesa boards be used for any ground? or does it have to corelate with the device ur wiring in, in the area that device goes.
[16:27:28] <archivist> airport security chases errant user for shorting the lights
[16:28:44] <archivist> best to corelate where possible
[16:29:14] <Gamma-X> cause theres ground in differant spots and im not sure wich one to put where.
[16:29:26] <Gamma-X> archivist is it imperative to do that or will it be ok?
[16:29:56] <SWPLinux_> SWPLinux_ is now known as SWPLinux
[16:30:31] <archivist> ground loops can/do cause problems so keep them with the signals
[16:30:33] <SWPLinux> hmmm. looks like I've got a little configuration to do for suspend
[16:31:20] <Gamma-X> ill give u an example whats the ground on pin 21 used for?
[16:34:05] <jepler> with a continuity tester, I'm sure you'll see that the GND on TB1 pin 21 is connected to all the other GNDs. However, the practical use of that GND wire and trace on the board is to reduce the coupling between IDX2 and AOUT2
[16:34:28] <archivist> 21 gnd is for the signal next to it
[16:34:47] <SWPLinux> it may also be a convenience terminal, so you don't have to connect all the ground wires to the same spot
[16:35:03] <Gamma-X> ahhh jepler i have to say that was a verry precise answer
[16:36:08] <jepler> http://ece.colorado.edu/~mcleod/teaching/EandM3400/Lab%20Book/Lab_5.pdf
[16:38:37] <seb_kuzminsky> hey, colorado.edu is where i work!
[16:40:17] <Gamma-X> ok well scales and servos are hooked up, thats all for the 7i33
[16:40:36] <Gamma-X> hmmmm how the hell am i gunna do this vfd bullshit lol
[16:42:28] <SWPLinux> are the scales working?
[16:42:42] <Gamma-X> idk i didnt go that far yet im just talkin about to the mesa cards! hahah
[16:43:32] <SWPLinux> you should check that the scale feedback is working, that's very important for moving motors
[16:43:56] <Gamma-X> ikm goin to
[16:43:57] <SWPLinux> and you can check it by moving the table - no power to the spindle (or servos, depending) necessary
[16:43:59] <SWPLinux> heh
[16:44:26] <Gamma-X> but its like 9 degrees outside and i dont feel like taking my computer outside and setting it up! lol
[16:44:33] <Gamma-X> that and I havnt configured hal yet
[16:45:00] <Gamma-X> honeslty im kinda lsot on it and i did read.
[16:45:29] <SWPLinux> feedback is what prevents the servos from crashing through limits, so it's a good thing to check early on
[16:47:45] <Gamma-X> ok
[16:47:51] <cradek> you must have working estop and limit switches that disable the amps before you apply any power to the motors
[16:47:54] <Gamma-X> i gotta hook up my limits and e stop
[16:48:06] <SWPLinux> heh
[16:48:09] <Gamma-X> lol
[16:49:53] <Gamma-X> oh i now have a p4 1.4 ghz and 512 pc133 ram controllin my emc machine
[16:50:17] <SWPLinux> ok, how does it perform for RT?
[16:50:44] <Gamma-X> whats rt
[16:50:56] <SWPLinux> realtime
[16:51:06] <Gamma-X> ohhh idk
[16:51:13] <SWPLinux> that's the kind of question that makes me concerned for your safety :)
[16:51:21] <Gamma-X> dont worry about me
[16:51:23] <Gamma-X> im always fine
[16:51:31] <SWPLinux> well ok then
[16:52:03] <Gamma-X> can anyone give me a few starting steps on hal? like where to begin?
[16:52:20] <cradek> reading the hal tutorial
[16:52:25] <Gamma-X> i did
[16:52:29] <SWPLinux> then start with the mesa sample config, I'd say
[16:52:34] <skunkworks_> read it again :)
[16:52:54] <SWPLinux> yeah, and don't come back until you can answer every question on the test!
[16:53:03] <Gamma-X> hahaha
[16:54:37] <SWPLinux> hmmm. I wonder if my phone "just works" as a USB modem
[16:55:47] <Gamma-X> if its got bluetooth prolly if it has windows on it then yes
[16:56:22] <SWPLinux> it has blutoth, but it's verizon-crippled bluetooth
[16:56:25] <jepler> I was excited to learn that my new phone does. and also puzzled that the few minutes I used it for haven't appeared on my online statement yet (voice minutes appear immediately)
[16:56:49] <SWPLinux> I think data calls are like voice calls in many cases
[16:57:06] <SWPLinux> or is that in EDGE/GPRS mode (or whatever)
[16:57:19] <Gamma-X> edge
[16:57:48] <cradek> mine works that way too - very handy
[16:57:52] <jepler> this is on sprint's network (virgin mobile pay as you go), I don't know much about the technologies..
[16:58:18] <jepler> but .. I plugged in the USB, and it appeared as /dev/ttyACM0
[16:58:26] <SWPLinux> me either - I just know a few of the acronyms :)
[16:58:27] <cradek> yep
[16:58:32] <SWPLinux> ok, mine does as well
[16:58:37] <jepler> it has bluetooth, but serial-over-bluetooth didn't work
[16:59:42] <SWPLinux> did you notice the connection speed?
[16:59:50] <SWPLinux> in rough terms
[17:00:00] <jepler> it didn't print it in the CONNECT message. It seemed pretty sluggish and slow, though
[17:00:20] <SWPLinux> ok, so possibly modem-like, rather than 3G speed
[17:00:33] <cradek> oh wait
[17:00:38] <cradek> you are not calling an actual modem?
[17:00:40] <Gamma-X> prolly edge
[17:00:41] <cradek> that's what I do with mine
[17:00:44] <Gamma-X> 3g is fast
[17:00:48] <SWPLinux> the EDGE and EVDO networks are supposed to do 700kbits to 1.4 megabits
[17:00:50] <cradek> so of course I get modem speed
[17:00:50] <jepler> yeah I call my ISP's dialup number
[17:00:54] <jepler> what else would I call?
[17:01:00] <cradek> yeah we are not talking about the same things then
[17:01:03] <SWPLinux> ok, so you're at 14.4k or something
[17:01:05] <SWPLinux> heh
[17:01:17] <Gamma-X> ud connect to ur phone providers isp through an ip]\
[17:01:19] <cradek> does SWPLinux know something we don't?
[17:01:26] <SWPLinux> no way! :)
[17:01:44] <cradek> I don't have/want any kind of expensive data plan
[17:01:49] <SWPLinux> if you have data service from the cell carrier, you can get much faster connections
[17:01:52] <cradek> sure
[17:02:01] <Gamma-X> unlimited for 20 bucks a month
[17:02:01] <SWPLinux> right, me either (Because Verizon is so damned annoying and expensive)
[17:02:09] <SWPLinux> where?
[17:02:16] <Gamma-X> verizon sucks balls
[17:02:21] <Gamma-X> att
[17:02:38] <SWPLinux> no ATT service in my hometown, so not so useful for me
[17:02:44] <Gamma-X> wow
[17:02:55] <Gamma-X> sprint
[17:02:57] <Gamma-X> same thing
[17:03:08] <SWPLinux> I don't think we have any GSM providers yet
[17:03:17] <Gamma-X> where do u live?!?
[17:03:19] <SWPLinux> (or us-fubared GSM)
[17:03:28] <SWPLinux> Burlington, VT
[17:03:37] <Gamma-X> oh snap!
[17:03:38] <SWPLinux> area
[17:03:48] <Gamma-X> SWPadnos u should come down to ny and help me with my machine!
[17:03:53] <SWPLinux> hgeh
[17:03:58] <SWPLinux> where in NY?
[17:04:02] <Gamma-X> long island
[17:04:07] <lewin1> lewin1 is now known as lewing
[17:04:12] <SWPLinux> oh, that new york ;)
[17:04:17] <Gamma-X> haha yeah
[17:04:29] <SWPLinux> which town? ( you said once but I don't remember)
[17:04:36] <Gamma-X> blue point ny.
[17:04:46] <SWPLinux> how far from Asharoken is that?
[17:04:56] <Gamma-X> pretty far i believe
[17:05:03] <SWPLinux> or Brooklyn?
[17:05:11] <Gamma-X> wait
[17:05:19] <Gamma-X> y do u say asharoken?
[17:05:27] <SWPLinux> yes
[17:05:29] <Gamma-X> uve been there?
[17:05:30] <SWPLinux> oh
[17:05:41] <SWPLinux> no, I have an associate who has a house there
[17:05:46] <Gamma-X> ohhhh
[17:05:47] <Gamma-X> nice area!
[17:05:54] <Gamma-X> he lives right by where i work
[17:05:55] <SWPLinux> Rube Goldberg's old place ;)
[17:06:06] <Gamma-X> i work at the northport power plant.
[17:06:16] <SWPLinux> ok (never been there)
[17:06:18] <Gamma-X> where he lives he can see the smoke stacks of where i work lol
[17:06:29] <SWPLinux> I've been to Port Jefferson (?), but that was a while ago
[17:06:36] <Gamma-X> nice area aswell
[17:06:39] <Gamma-X> its 15 mins from me
[17:06:43] <SWPLinux> probably not, his beach house faces Connecticut ;)
[17:06:58] <Gamma-X> SWPadnos i guarentee he can see it haha
[17:07:06] <Gamma-X> cause i can see almost all the ebach houses
[17:07:09] <SWPLinux> oh right - no height limits in NY
[17:07:13] <Gamma-X> yup
[17:07:29] <Gamma-X> how do u know him?
[17:07:44] <SWPLinux> I designed a camera system for him
[17:07:57] <SWPLinux> he lives in Dallas, but he has a house on Long Island also
[17:08:00] <Gamma-X> ahhh
[17:08:02] <Gamma-X> ok
[17:08:13] <SWPLinux> aha - East Setauket, that's where I went before
[17:08:21] <Gamma-X> if u ever feel like takin a weekend trip down here let me know
[17:08:32] <Gamma-X> i worked in east setauket delivering for ups
[17:08:33] <SWPLinux> I will (but don't hold your breath ;) )
[17:08:49] <Gamma-X> hahah
[17:09:02] <SWPLinux> oh - I drove down to get some custom-frequency crystals a long time ago
[17:09:09] <Gamma-X> ?
[17:09:12] <Gamma-X> for what
[17:09:59] <SWPLinux> a radio transmitter we were designing
[17:10:00] <SWPLinux> 68.807 MHz
[17:10:19] <Gamma-X> im assuming u make good money in w/e u do haha
[17:10:21] <Gamma-X> http://maps.google.com/maps?q=Asharoken,+NY,+United+States+of+America&sa=X&oi=map&ct=title
[17:10:25] <SWPLinux> sometimes
[17:10:33] <SWPLinux> other years, I go without pay
[17:10:36] <Gamma-X> click that and look at the arrow, look to the right there are 2-3 water ways
[17:10:57] <SWPLinux> yep
[17:10:59] <Gamma-X> the first 2 are northport power plant, or click on satelite image
[17:11:41] <Gamma-X> and if u were in port jeff uve seen the other power plant I work at.
[17:12:25] <SWPLinux> heh
[17:12:47] <SWPLinux> I think if you look way out on N. Creek Road, that's where the house is
[17:12:51] <SWPLinux> I'm not sure exactly
[17:13:00] <Gamma-X> ok
[17:13:18] <SWPLinux> on the west side of that little "peninsula"
[17:14:37] <Gamma-X> got it
[17:15:26] <Gamma-X> he can see the stacks no doubt u can see them from conneticout
[17:15:51] <Gamma-X> how should I hook up the limit switches?
[17:15:59] <SWPLinux> probably, when the trees aren't leafy
[17:16:02] <Gamma-X> in series?
[17:16:24] <SWPLinux> for testing or for real?
[17:16:30] <Gamma-X> real
[17:16:42] <SWPLinux> it depends on what you want
[17:16:51] <Gamma-X> ...explain please
[17:16:57] <cradek> they need to disable the amps
[17:17:06] <cradek> you have to figure out how to do that with your amps
[17:17:14] <cradek> sorry for butting in
[17:17:19] <Gamma-X> as far as I know they run through my amps
[17:17:29] <Gamma-X> i dont mind.
[17:17:29] <SWPLinux> series is reasonably easy and useful - you only have one wire (pair) going from the machine to the control cabinet (with the motor drives)
[17:17:43] <SWPLinux> if that's the case, then you probably don't have much choice in how to wire them
[17:18:14] <Gamma-X> they run through the amps and into the control cabinet.... well the old one so i still have the wires available to me.
[17:18:37] <SWPLinux> "through the amps" doesn't make sense to me
[17:18:45] <Gamma-X> threw?
[17:18:54] <Gamma-X> uhhhh
[17:19:15] <SWPLinux> either they're in parallel with a disable input on the amps, or the amps have an aux output that feeds the switch signals to the control ...
[17:19:33] <Gamma-X> http://www.cnczone.com/forums/showthread.php?t=17510
[17:19:42] <Gamma-X> post #8
[17:19:44] <SWPLinux> they could also be in series - the amps could have the ability to fault the e-stop chain
[17:20:31] <Gamma-X> the way i turn the amps on is by shorting the estop and then un shorting.
[17:22:11] <Gamma-X> the way it was orriginaly done was u hit e stop, take e stop off then hit reset and they start to whistle
[17:22:51] <SWPLinux> are those two limit switch inputs for the two directions, or are they limit and overtravel? (ie, two limits)
[17:23:09] <Gamma-X> uhhh
[17:23:22] <SWPLinux> pins 6 and 7 on J1
[17:23:34] <SWPLinux> though those aren't necessarily inputs, they could be outputs (that list doesn't say)
[17:24:01] <Gamma-X> idk
[17:24:02] <Gamma-X> i can find out
[17:24:17] <SWPLinux> ok - that sounds like a good plan :)
[17:27:09] <Gamma-X> ok i found out
[17:27:27] <Gamma-X> he said u jsut gotta find out if when u strap it they run or un strap and they run,
[17:28:09] <Gamma-X> theres 3 pins 6,7 for the switches and pin 9 for common
[17:29:18] <SWPLinux> right - I noticed that pin 8 (an output) also uses 9 for common
[17:29:42] <Gamma-X> yup
[17:30:08] <Gamma-X> SWPadnos brb gunna go smoke, i know ull be sitting there for a minute! lhaha!
[17:30:12] <SWPLinux> which would mean that some digital output would be using the same ground as a switch mounted on the machine ...
[17:30:21] <SWPLinux> no - actually we should be boarding in 10-15 minutes
[17:30:26] <Gamma-X> damn
[17:30:28] <Gamma-X> ill sit here then
[17:30:33] <SWPLinux> heh
[17:30:43] <SWPLinux> not that I'm much help with this stuff :)
[17:30:53] <Gamma-X> so should I wire them in series or all differant?
[17:30:57] <SWPLinux> I do have a few AMC servo drives though ;)
[17:31:04] <Gamma-X> i got a 7i37 wich should be enough
[17:31:24] <SWPLinux> it depends on what you want ... :)
[17:31:35] <Gamma-X> whats the most safest?
[17:31:40] <SWPLinux> if you want any limit switch to disable all amps, then wire all in series
[17:31:50] <Gamma-X> yeah i do.
[17:32:14] <Gamma-X> SWPadnos thats the msot safest correct?
[17:32:29] <SWPLinux> actually, the limits are already connected between machine and servo drive, right?
[17:32:37] <Gamma-X> uhhh
[17:32:38] <Gamma-X> yeah
[17:32:47] <Gamma-X> but then they go back to the controller
[17:32:58] <SWPLinux> yes, it's probably the safest, but it's not very useful for moving off the limit, is it? :)
[17:33:12] <SWPLinux> which wire goes to the controller? the one from pin 8?
[17:33:15] <Gamma-X> well i can manualty movie it
[17:33:40] <Gamma-X> no
[17:33:51] <Gamma-X> all limit switches the + and - get wired to it.
[17:33:53] <SWPLinux> no, leave the switches alone - they should be wired so the amps will be "safe"
[17:34:23] <Gamma-X> http://imagebin.org/13227
[17:34:26] <Gamma-X> look on the right side
[17:34:55] <SWPLinux> argh
[17:35:02] <SWPLinux> ih, here it comes
[17:35:04] <SWPLinux> oh
[17:35:29] <Gamma-X> ?
[17:35:42] <SWPLinux> the "oh" was correcting the previous "ih"
[17:35:47] <Gamma-X> ahhh
[17:36:06] <SWPLinux> well, I guess that pinout tells you how they're wired, huh?
[17:36:07] <Gamma-X> im puzzled on how it is set uop
[17:36:20] <Gamma-X> well kinda
[17:36:28] <SWPLinux> you have 6 wires coming to that connector, they're not wired together
[17:36:33] <SWPLinux> (that's my bet anyway)
[17:36:37] <Gamma-X> correct
[17:36:50] <SWPLinux> you can use 6 separate inputs to EMC, which should be the most flexible
[17:37:10] <SWPLinux> usually, people wire things in series because it's easier - you only have a single cable coming off the machine
[17:37:18] <Gamma-X> ok
[17:37:30] <SWPLinux> if it's already set up to disable whatever needs disabling, and the wiring is already done, you may as well leave it
[17:37:45] <SWPLinux> that will allow you to jog off the limits (if the amps allow it), for example
[17:38:16] <SWPLinux> if you use a limit switch as a home input, it will also allow you to home all 3 axes simultaneously (I think)
[17:38:28] <Gamma-X> ok
[17:38:42] <cradek> you cannot home on a limit switch if that limit switch disables the amp
[17:38:48] <Gamma-X> this will be a headache but i actualy worked out a deal with the creator of my control who worked for anilam! lol
[17:38:56] <SWPLinux> true
[17:39:08] <Gamma-X> im giving him a power supply and hes giving me all the info i need.
[17:39:09] <cradek> homing on limit switches is for small machines only
[17:39:10] <Gamma-X> anytime i want it
[17:39:11] <SWPLinux> cradek: what if it only disables further travel in that direction?
[17:39:24] <Gamma-X> cradek from past experience it shuts down the servo
[17:39:25] <cradek> SWPLinux: it'll still FE because it can't decel under power
[17:39:31] <SWPLinux> ok, good point
[17:39:39] <Gamma-X> so i should just do it in series
[17:39:52] <cradek> if you end up without home switches, you can use index-only homing
[17:40:06] <Gamma-X> i dont think the machine had homing switches
[17:40:07] <SWPLinux> they're wired in parallel already, you don't have much choice unless you want to rewire it all
[17:40:32] <SWPLinux> EMC will shut off all the motors if any limit is hit, I believe
[17:40:46] <Gamma-X> ok
[17:40:47] <SWPLinux> the offending motor will have already been turned off in hardware
[17:40:52] <Gamma-X> so series is the way to go!
[17:40:59] <SWPLinux> argh!
[17:41:14] <Gamma-X> haha
[17:41:27] <SWPLinux> they are already wired in parallel - you have six limit signals for EMC
[17:41:57] <Gamma-X> i know
[17:41:59] <SWPLinux> you can make some circuitry and "OR" (or and) them together, or you can just connect all of them to EMC
[17:42:22] <Gamma-X> wow that middle aprt is confusing
[17:42:35] <SWPLinux> I'm pretty sure that they'll already be wired to provide for safety concerns, probably by disabling the servo amps
[17:42:46] <Gamma-X> SWPadnos correct.
[17:42:49] <SWPLinux> I'm saying that you can just connect all 6 wires to the Mesa card
[17:42:55] <Gamma-X> SWPadnos thats how it ran when it was first up and running
[17:43:01] <SWPLinux> and wire them to HAL - there are 6 limit inputs to the motion controller
[17:43:10] <Gamma-X> ok
[17:43:32] <Gamma-X> im just trying to do as little as possible with hal
[17:43:36] <Gamma-X> its so god damn scary
[17:43:57] <Gamma-X> hey ill brb gotta smoke. if i misss u SWPLinux have a safe flight
[17:44:10] <SWPLinux> you have the choice of (a) rewiring the limits and possibly screwing something up, (b) making some custom hardware to combine those 6 signals, or (c) editing a text file ...
[17:44:15] <SWPLinux> see you -about to board
[17:44:21] <SWPLinux> hasta everyone
[17:44:24] <jepler> see you SWPLinux
[17:44:27] <cradek> safe trip
[17:44:30] <SWPLinux> thanks
[17:49:39] <archivist> cradek does the homing, test on make or break for its 0 position
[17:50:05] <cradek> archivist: you can do any of many things
[17:50:39] <cradek> linuxcnc.org, documentation, html, homing configuration
[17:50:58] <archivist> ah ok, Im wondering wether to make an amplified movement so I can use cheaper switches
[17:51:32] <cradek> amplified? like a lever arrangement?
[17:51:48] <archivist> yes
[17:52:10] <cradek> even cheap everyday microswitches give surprising repeatability - I advise you test your cheap switches first
[17:52:39] <cradek> helps to hit them straight-on
[17:53:03] <cradek> but even with ramps I get good repeatability: http://timeguy.com/cradek/01198731403
[17:53:57] <cradek> with a tenths indicator I can easily see each step (1/3200 inch) and I get the same one over and over
[17:54:26] <archivist> nice
[17:55:06] <cradek> don't know about long term, but in the short term if I home 20 times I get the same step each time
[17:55:08] <archivist> must find my box of bits with microswiches in it
[17:55:44] <archivist> I looked as some specs before xmas and some were good for the price
[17:56:31] <cradek> mine are junkbox so no specs :-)
[17:56:33] <cradek> http://timeguy.com/cradek-files/cnc/lathe/DSCN6295.JPG
[17:56:34] <archivist> but if a ramp is working that well! goody
[17:56:53] <cradek> in this one you can barely see the setup for the same kind of switch but head-on
[17:57:05] <cradek> it smacks into the saddle
[17:57:25] <cradek> the switch is slightly back from the edge of the mount so there's a hard stop to protect it
[17:57:33] <archivist> most of my machine is junk box
[17:58:13] <archivist> Im thinking of a spring to protect the switch
[17:58:15] <cradek> the lathe X homes as it pulls off the switch, so the backlash is the right way (for outside cuts)
[17:59:07] <archivist> have you done similar for the rotary axis
[17:59:24] <cradek> nope I just home them by eyeball
[17:59:30] <archivist> heh
[17:59:56] <archivist> near enoufg technique
[18:00:06] <cradek> well there's a mark where the handwheels used to be - I can get the right step by eye
[18:00:29] <cradek> (or at least close enough)
[18:00:50] <archivist> no longer visible on this on
[18:00:55] <archivist> one
[18:01:08] <cradek> it's not clear to me how to put home on an infinitely rotating table
[18:01:41] <archivist> well a ramp(bump) could actuate a switch
[18:02:00] <cradek> yes
[18:03:12] <cradek> index pulse would be nice for a rotary, you really want the home on the 'good' side of the worm
[18:03:44] <archivist> for gear cutting 0 doesnt matter anyway just as long as Im consistent
[18:04:09] <cradek> true, don't sweat it I guess
[18:04:20] <cradek> (on mine both of the zeroes definitely matter)
[18:04:55] <archivist> im making sure im unidirectional in my gcode to ensure no backlash from the rotary
[18:05:40] <cradek> someday I bet we'll want the special handling of infinite rotaries
[18:06:15] <cradek> then you'd just program with all positive numbers and not have to worry about the old value
[18:06:46] <archivist> yes move to absolute, but only clockwise etc
[18:25:54] <archivist> cradek those pitman servos from HP plotters?
[18:26:12] <archivist> servo motors
[18:26:45] <seb_kuzminsky> i donno where cradek got his, but my local electronics surplus place had a bunch for about $12 each
[18:27:06] <seb_kuzminsky> pittman 8XXX, not 9XXX like cradek has
[18:27:50] <archivist> * archivist has a 9413D319 in his hand
[18:28:32] <seb_kuzminsky> pittman's docs on their website are pretty good :-)
[18:28:42] <archivist> HP part no probably 0745-60104
[18:29:01] <archivist> ah must look
[18:31:30] <archivist> heh /me sees same number on cradeks lefthand motor, now I know how big that lathe is
[18:32:59] <archivist> must look out for more toys to disassemble
[18:33:21] <seb_kuzminsky> did you get yours from an HP plotter?
[18:33:44] <archivist> yes
[18:34:59] <archivist> mine dont have the IC on the pcb though
[18:35:34] <seb_kuzminsky> which IC? the driver?
[18:36:31] <archivist> on the pcb at the back of the motor (opto reader)
[18:36:41] <archivist> buffer probably
[18:38:21] <seb_kuzminsky> oh on the encoder? yeah they come with a bunch of different encoders. Does it say HEDS and a 4-digit number on it?
[18:40:00] <Gamma-X> how would i hook up a limit switch with a + and a - on the 7i37?
[18:42:53] <Gamma-X> ?
[18:50:07] <Gamma-X> it turns out the limit switches wernt even hooked up in the control....
[18:53:05] <Gamma-X> do i need to wire the limit switches to emc? or can i let the servo amps worry about it
[18:53:52] <seb_kuzminsky> i think you'd want emc to know
[18:55:34] <Gamma-X> is emc a open or closed loop system?
[18:55:47] <Gamma-X> i gotta figure out if my switches are open or closed loop.
[18:57:36] <skunkworks_> Gamma-X: you are scaring us again...
[18:59:24] <ALS> focus gamma focus
[19:16:33] <Gamma-X> hahah\
[19:16:56] <Gamma-X> i went out side to check sumtin
[19:17:19] <Gamma-X> skunkworks how should I hook up te limits?
[19:17:38] <seb_kuzminsky> lerneaen_hydra: hej en svensk! jag med fast jag bor is usa nu
[19:18:25] <lerneaen_hydra> nämen sedär, en till från sverige. Vi börjar snart ta över kanalen. bork bork bork
[19:18:45] <seb_kuzminsky> heh
[19:24:06] <cradek> seb_kuzminsky: do they still have those motors? I'd love to have a few more
[19:25:07] <seb_kuzminsky> I'll check. You sure you want the 8xxx's? They're not as torque-y.
[19:25:18] <cradek> oh, hmm, maybe not
[19:25:31] <cradek> I have some smaller, what I'd like is some more about this size
[19:25:38] <cradek> thanks anwyay though
[19:25:43] <seb_kuzminsky> check the pittman lcm document and see if they're in spec for you
[19:26:28] <Gamma-X> hey cradek on the 7137 if ur lookin at teh card with isolated i/o to the right would i put the limit switches all in the left row.... positive then negative and so on?
[19:27:13] <cradek> good gravy, Gamma-X - read the docs and figure it out - you have the card, the docs, and the mill - I don't
[19:27:34] <Gamma-X> cmon! im so scared to mess it up! hahaha
[19:28:17] <cradek> you either have to study the situation and become confident and capable, or you should stop before you damage yourself or (less important) the mill
[19:28:58] <Gamma-X> thats why i stopped and asked someone i trust more than myself with this stuff haha
[19:29:17] <jepler> consider the diagram here: http://en.wikipedia.org/wiki/Opto-isolator#Application
[19:30:01] <cradek> maybe you should consider getting someone out there to help you, at least with the safety-related parts of the retrofit
[19:31:12] <Gamma-X> SWPLinux is willing, but it may take a while so he said
[19:31:49] <ALS> you got time your only 22
[19:32:04] <Gamma-X> u remembered! thanks.
[19:33:36] <ALS> do you have a pc running emc yet?
[19:33:59] <jepler> the 7i37 board contains something like R1, R2, D1, Q1 for each isolated input. You have to find some parts of your system that are equivalent to V1 and S1, and connect that in the right way to two of the 7i37 pins (e.g., pins 1 and 2, IBIT0+ and IBIT0-). You could literally start with a microswitch and a 9V battery, and observe the state of the 5i20's input bits through halmeter in order to understand how the circuit works and behaves
[19:35:57] <Gamma-X> ALS yes i do
[19:36:07] <Gamma-X> jepler i think i figured it out
[19:38:17] <alex_joni> Gamma-X: why do I have a feeling you'll have other questions :)
[19:39:53] <ALS> make drawings of your circuits, why and were they hook up
[19:42:41] <Gamma-X> alex_joni cuase i know i will 2
[19:43:31] <alex_joni> ok, if you're so confident you can with only 2, you'll have 2 more questions left
[19:45:51] <alex_joni> free ones I mean :)
[19:47:36] <Gamma-X> hashaha
[19:50:12] <alex_joni> Gamma-X: you'll need to provide favours for the rest
[19:50:28] <alex_joni> small things like proofreading docs, writing wiki pages :P
[19:53:44] <Gamma-X> ouch
[19:53:50] <Gamma-X> writing a wiki page! hahaha
[19:53:56] <Gamma-X> i think i can do this on my own hahaha
[19:54:50] <Gamma-X> ull read in the paper, 22 year old young man slayed by his cnc machine when it all of a sudden turned into an auto bot
[19:55:09] <Gamma-X> ok limits are hooked up
[19:55:39] <Gamma-X> now for e stop
[20:31:49] <fretless85> hey
[20:32:14] <jepler> Aieeee! Stop!!!!!! <--- impression of a man who got his e-stop wired wrong
[20:32:44] <fretless85> rofl
[20:33:52] <cradek> jepler: you forgot the "squish" at the end
[20:34:22] <fretless85> squish? you mean "bam!"
[20:34:52] <cradek> could be either noise I suppose
[20:35:02] <cradek> I think squish is worse
[20:35:30] <fretless85> yea
[20:35:54] <fretless85> keep your fingers out of the way...
[20:37:28] <skunkworks_> squish - then bam
[20:37:28] <fretless85> in about 7 years as a milling machine operator i never got to hit the emergency stop...but its still good to know you have it ;)
[20:37:29] <lerneaen_hydra> that's why you use some other person that happens to be standing nearby as a meat-guard
[20:37:52] <lerneaen_hydra> fretless85; bah, you're machining at far too conservative speeds then ;)
[20:38:09] <lerneaen_hydra> and mostly thinking too much before you mill
[20:38:16] <fretless85> there is an nc stop tho...
[20:38:27] <fretless85> thats right
[20:38:50] <fretless85> i got no second try
[20:39:10] <fretless85> heavy parts 4-40tons
[20:39:39] <fretless85> you got to think before you mill ;)
[20:39:56] <lerneaen_hydra> that's pretty heavy actually
[20:40:12] <lerneaen_hydra> how often do you break off tools not just due to wear?
[20:40:29] <fretless85> you mean crash?
[20:41:28] <fretless85> most tools are hard to break off due to there diameter *g*
[20:41:50] <lerneaen_hydra> haha, that always simplifies things
[20:42:39] <cradek> a mistake I made with a large tool pushed the work out of the vise - if it had been a mistake in Y instead of X, I'm sure it would have snapped off
[20:42:39] <fretless85> yea but last week i killed an hm endmill diameter 40
[20:43:01] <lerneaen_hydra> hm?
[20:43:34] <fretless85> im german sorry hartmetal its called back here
[20:43:41] <fretless85> cabite metal?
[20:43:49] <cradek> carbide?
[20:43:53] <fretless85> yea
[20:43:57] <lerneaen_hydra> oh, carbide
[20:44:02] <cradek> that's an expensive endmill then
[20:44:03] <fretless85> sry for the miss spelling
[20:44:08] <lerneaen_hydra> hårdmetall in swedish, seems like a word-for-word translation :)
[20:44:23] <lerneaen_hydra> hard-metal
[20:44:26] <fretless85> yea
[20:45:16] <fretless85> i dont got it to mill with rapid feed,,,no idea why,,,
[20:45:32] <fretless85> :D
[20:47:01] <fretless85> shit happens...
[20:47:39] <lerneaen_hydra> most definitely
[20:48:22] <fretless85> someone who dont work, makes no mistakes...
[20:48:56] <lerneaen_hydra> and the inverse of that too
[20:49:23] <fretless85> thats the truth
[20:49:32] <fretless85> in german
[20:49:38] <fretless85> wer nichts macht, macht keine fehler
[20:49:41] <fretless85> ;)
[20:50:45] <lerneaen_hydra> heh, fehler is almost the same as fel in swedish (same meaning)
[20:51:09] <fretless85> when you mess up something...you got to know how to weld :P
[20:51:45] <fretless85> if you can weld it...
[20:52:25] <Jymm> OT Question... When you mill a thru hole where the end mill is gonna hit the table, How do you usually set that up?
[20:53:05] <fretless85> get space between the working space and the table?
[20:53:06] <cradek> with air underneath
[20:53:24] <cradek> if it's in a vise, just use parallels
[20:53:38] <fretless85> right
[20:53:39] <lerneaen_hydra> if it's a smallish peice, some plywood under, or in a vise with an air gap
[20:53:47] <cradek> if it's on the table, use scrap, or if you need it flat, spacers like 123 blocks
[20:54:35] <Jymm> I get that =) But But I have this L shaped chassis that's like 11" by 9" 16ga aluminum, so it's gonna be funky just mounting it to the table a bit.
[20:55:07] <Jymm> oh, by 17" long
[20:55:25] <lerneaen_hydra> oh, if it's large and flat (sheet metal), I clamp it to the table with some scrap plywood under
[20:55:41] <fretless85> plywood? gna
[20:55:50] <lerneaen_hydra> gna?
[20:55:52] <fretless85> use plastic
[20:56:05] <Jymm> lerneaen_hydra: Ok, I can see the plywood - as it would support the whole 17" w/o bowing the sheet
[20:56:32] <lerneaen_hydra> fretless85; plastic is probably better, plywood scraps are free ;)
[20:56:45] <Jymm> Just seems like swarf woulf collect in the wood and scratch the finish.
[20:57:17] <lerneaen_hydra> hmm, I haven't had any issues like that, maybe you could test with something similar and see if that would happen?
[20:57:59] <Jymm> This is gonna be REALLY hard as it is, because of the L shape, it's gonna block the entire fron of the mill
[20:58:07] <lerneaen_hydra> ugh
[20:58:14] <lerneaen_hydra> doesn't sound too fun
[20:58:30] <Jymm> I'll have to look from the sides - yeah, no doubt.
[20:58:36] <ds2> \
[20:58:39] <lerneaen_hydra> I'd prefer to have something solid under the chassis so it doesn't bow down
[20:59:08] <Jymm> Oh, maybe that dark brown stuff.... 1/8" thick
[20:59:11] <lerneaen_hydra> preferably lots of clamps to stop it from rising up (if you're using twisted endmills)
[20:59:23] <lerneaen_hydra> or whatever they're called
[21:00:28] <fretless85> the more teeth the better for sheet metal
[21:00:32] <Jymm> wth is that stuff called again (agrh), they use it for bench tops, harder than shit. usually you have to drill it before screwing it down
[21:00:52] <Jymm> like plyboard, but seriously desne
[21:00:55] <Jymm> dense
[21:01:05] <ALS> masonite?
[21:01:10] <Jymm> that's it!
[21:01:12] <lerneaen_hydra> oh, uh, I know what you mean
[21:01:12] <fretless85> epoxy resin wood?
[21:01:18] <Jymm> masonite
[21:01:33] <fretless85> in germany its called pertinax
[21:01:34] <lerneaen_hydra> wtf, not masonite, that's just pressed sawdust and glue isn't it?
[21:01:53] <Jymm> lerneaen_hydra: It is, but really dense
[21:02:04] <ALS> peg board stuff
[21:02:07] <Jymm> lerneaen_hydra: less chanse of swarm getting embedded in it
[21:02:17] <Jymm> swarf
[21:02:18] <lerneaen_hydra> hmm, ok, there's something else though that's a lot harder and more durable
[21:02:27] <lerneaen_hydra> it cracks like ceramic
[21:02:39] <lerneaen_hydra> used for high-wear tabletops and the like
[21:02:52] <fretless85> like ceramic? wow...
[21:03:01] <ALS> if its held down good shouldn't get under
[21:03:02] <Jymm> lerneaen_hydra: yesh, masonite for tabletops.
[21:03:08] <lerneaen_hydra> yeah, I can't quite seem to recall what it's called
[21:03:35] <ALS> fermica?
[21:03:44] <lerneaen_hydra> no, this is something else, cheap applications have a thin layer, a couple mm thick
[21:03:59] <Jymm> formica is a no no to machine.... formaldyhide in it
[21:03:59] <lerneaen_hydra> ALS; hmm, can't say I recognise the name
[21:04:40] <lerneaen_hydra> ALS; hmm, could well be
[21:05:59] <Jymm> I machined my first metal piece ever last night - and didn't screw it up either! LOL
[21:06:18] <ALS> they use router to trim the edges
[21:06:21] <skunkworks_> Jymm: your required to post a picture...
[21:06:29] <ds2> Jymm: and are you IRCing from home or the hospital? =) j/k
[21:06:50] <Jymm> skunkworks It's just a penny holder - no biggy
[21:08:04] <lerneaen_hydra> a penny holder? O_o
[21:08:33] <Jymm> Glad I took the safety class, it let me run one mill for SWPadnos (after he set it up), while he was working on the other mill.
[21:09:30] <Jymm> I can now appreciate a rotary table =)
[21:10:31] <Jymm> ds2: you should check that place out, pretty cool. It's in Menlo Park. Right at the dumb bringe
[21:10:36] <Jymm> bridge
[21:10:42] <ds2> Jymm: what place?
[21:10:52] <Jymm> http://techshop.ws/take_classes.html?a=1&i=2783709
[21:11:08] <ds2> oh I been there several times. I am disappointed by the machines and tooling offered
[21:11:30] <Jymm> Ah, well better than nothing in our case.
[21:11:43] <ds2> it is fine if you have no other means
[21:11:58] <ds2> and their classes are meager... I recommend the deanza shop classes instead
[21:12:00] <Jymm> I had to run over to HF and buy a set of drill bits becaue all of theirs wee chewed up.
[21:12:21] <ds2> even the basics, they are short of... they have chucks w/o keys for them
[21:12:23] <Jymm> The classes are safety and basic usage classes.
[21:12:58] <Jymm> They had chuck keys, but BYO tooling wouldn't hurt anything.
[21:12:58] <ds2> MCNC71 @ deanaza is better. the instructors at deanza know more and the shop is well equipped
[21:13:33] <Gamma-X> mr bouvier is sending me the turn on circuit for the control.... everything is going pretty smoothly.
[21:13:59] <Jymm> They got a laser, so I'm jazzed about that.
[21:14:15] <Gamma-X> Jymm wernt u helpin me with my retro fit?
[21:14:17] <ds2> the epilog and the dimension are redeaming features
[21:14:24] <Jymm> Gamma-X: not me
[21:14:31] <lerneaen_hydra> hmm techshop looks like an interesting concept, does it work?
[21:15:15] <Jymm> lerneaen_hydra: It seems so, especially if you dont have all that gear. $30/day or $100 month
[21:15:34] <lerneaen_hydra> what about assholes that mess up and/or break stuff?
[21:15:47] <ds2> lerneaen: a lot of what they have are in pretty poor shape and are used by people who donno what they are doing
[21:16:08] <ds2> stories I have heard include people trying to machine a incandescent lightbulb on the metal cutting lathe
[21:16:21] <lerneaen_hydra> O_o dude...
[21:16:26] <Jymm> lerneaen_hydra: It's cheap tooling, they dont guarntee accuracy on the machines. but if you dont have a cnc plasma cutter of your own, etc
[21:17:07] <ds2> they have a lot of harbor freight stuff... IMO, the crucible has better tooling equipment (but they cost more)
[21:17:10] <ds2> okay food time
[21:17:22] <lerneaen_hydra> right. are there workshops for people that know at least the basics of machining?
[21:17:25] <Jymm> ds2: crucible?
[21:17:36] <lerneaen_hydra> publicly joinable
[21:17:46] <ds2> http://www.thecrucible.org/
[21:17:53] <ds2> Jymm: they are up in oakland
[21:18:02] <Jymm> lerneaen_hydra: Yes, theres the BASIC safety class, then there are other class to actually LEARN how to do it "properly"
[21:18:15] <ds2> caters to artist types.. they also have a shaper
[21:18:16] <Jymm> ds2: thanks.
[21:18:55] <Jymm> They have a 3D printer, vacuum forming machine, the kinda stuff not everyone has in theri shop.
[21:18:56] <lerneaen_hydra> Jymm; uh, I was thinking about workshops as physical entities, ie. places with lathes, mills, sheet metal equipment etc.
[21:19:22] <Jymm> lerneaen_hydra: I'm not following, sorry.
[21:19:44] <lerneaen_hydra> something like techshop but without the idiots, and better machines
[21:20:38] <Jymm> lerneaen_hydra: Ah, gotcha. This is the only place I was even aware of. So no clue.
[21:21:18] <Jymm> lerneaen_hydra: Sounds like you mean something like this... http://store.thecrucible.org/product_info.php?cPath=1_10&products_id=1023&osCsid=e5b4a5126d5301372d63f3d27b81f28f
[21:21:53] <lerneaen_hydra> oh, ok. I can't quite see where the average person would do their machining, lathes and mills are prohibitively expensive, so building your own workshop for personal use is out of the question, where do people do their stuff?
[21:22:25] <lerneaen_hydra> hmm yeah I guess that fits the bill
[21:22:56] <lerneaen_hydra> I've been lucky enough to have access to workshops for quite some time, I can't see how I'd survive without them
[21:23:02] <Jymm> lerneaen_hydra: Well, I guess someone that has half a clue, or knows how to do it but doesn't have access to equipment
[21:25:25] <Jymm> I mean owning a BP for say $2000, doesn't cover anything, you still have to add on all the tooling, collets, clamps, etc etc etc
[21:25:46] <Jymm> place have 220 available to you =)
[21:25:50] <Jymm> plus
[21:25:53] <lerneaen_hydra> yeah exactly, the price can run away very quickly
[21:26:05] <lerneaen_hydra> lets not even get started on how much they cost here in sweden
[21:26:21] <Jymm> Hell, even if I wanted a quality mini mill, I never realized all the extras that I would need.
[21:26:23] <lerneaen_hydra> a micro-mill from china costs about $2000...
[21:28:25] <Jymm> Shit, even the bandsaw to cut the .75x2" al bar stock, then the other band saw to cut down some 1/4" al plate - it all adds up with the extras
[21:46:59] <Hugomatic> Hi, I'm having a problem with tool length compensation (10 gcode lines from the handbook). It looks like an AXIS display bug: I get a strange long line in the z axis. Fortunately, the tool does not follow the line, but Axis is a bit screwed up. Can anyone help?
[21:48:27] <Hugomatic> This is the simple program I'm running (I added the tool table at the end) http://pastebin.ca/867743, and this is the screenshot with the weird line (selected) http://imagebin.ca/view/NQwGo3Z.html
[21:52:28] <Hugomatic> Notice that the line is 50 mm long and that the compensation is 2 mm. Since 1 inch = 25.4 millimeters, this looks like a conversion error somewhere in Axis or EMC.
[21:53:03] <cradek> what version of emc is this?
[21:53:09] <skunkworks_> where did your machine start when you turned it on? looks like maybe when the program was loaded - z was not 0.
[21:53:17] <Hugomatic> 2.2.2
[21:53:25] <lerneaen_hydra> it's not that the tool was at that point when emc was loaded?
[21:53:38] <lerneaen_hydra> ^^^ what skunkworks said
[21:53:48] <Gamma-X> sweet i got my machine to power up. gotta have e stop on the machine internally connected then hit reset.
[21:54:03] <Hugomatic> Even when I home all before loading my file, I get the same result
[21:54:31] <Gamma-X> all cnc machine dont have home correct?
[21:54:36] <Hugomatic> My machine is a metric Sherline mill
[21:54:54] <Gamma-X> as far as I know myne doesnt have them.
[21:55:12] <Hugomatic> The funny thing is that the execution is OK. The tool doesn't go along the line.
[21:55:12] <ds2> a small show is not that expensive
[21:55:29] <ds2> a basic mill (import grade, manual) runs around $500 new
[21:55:51] <cradek> the length of tool 2 in the tool table is 2mm?
[21:55:58] <Hugomatic> cradek: yes
[21:56:31] <ds2> hmmm 2mm long tools... must not get a lot of chatter ;)
[21:56:42] <cradek> so at line 16 the actual motion you get is 2mm upward?
[21:56:57] <Hugomatic> cradek: yes
[21:57:49] <cradek> I see it's showing -50.8 for the lower extent. I agree it looks like a bug
[21:58:05] <cradek> can you file a bug report on sourceforge? I can't look at this right now and I don't want to forget it
[21:59:00] <Hugomatic> cradek: sure, I'd be happy to. Should I submit my sherline ini file as well?
[21:59:56] <cradek> it couldn't hurt. It may be that something in there smells like inches to AXIS
[22:02:04] <Gamma-X> can i set emc up to have a reset button? my servos will not come on unless i hit the reset button and i would like to keep it for functionality.
[22:02:19] <Gamma-X> a software layer reset.
[22:02:33] <Hugomatic> cradek: is this a duplicate 1825638? http://sourceforge.net/tracker/index.php?func=detail&aid=1825638&group_id=6744&atid=106744
[22:02:33] <alex_joni> Gamma-X: when you start emc you're in a state called estop
[22:02:41] <alex_joni> then you hit a key to get to estop reset
[22:02:50] <alex_joni> Gamma-X: from there you need to hit another key to get to machine on
[22:02:59] <alex_joni> only at machine on should your amps be enabled
[22:03:01] <jepler> Hugomatic, cradek: I do *not* see the problem using TRUNK sim/axis_mm.ini and hugomatic's tool table in sim_mm.tbl
[22:03:08] <Gamma-X> ahhhh
[22:03:36] <jepler> this enable signal is called axis.#.amplifier-enable-out
[22:03:40] <Gamma-X> alex_joni can i config that 2nd key to be my reset? thats kidna how my machine was setup to begin with? i just dont want a current going thorugh that circuit all the time. just a quick blip.
[22:03:40] <alex_joni> Gamma-X: the moving from estop to estop-reset is usually just a key (for micro, nano and other smallish mills)
[22:03:48] <jepler> one for each axis, though in any case I know about they're either all enabled or all disabled
[22:03:55] <alex_joni> jepler: right
[22:04:17] <alex_joni> Gamma-X: although on big machines moving from estop to estop-reset is usually only done if the external estop chain is ready
[22:04:21] <Gamma-X> cause my machine already has a hardware implementation of this. so it should be easy to set it up in emc.
[22:04:35] <alex_joni> Gamma-X: I don't understand what your reset key is
[22:05:05] <Gamma-X> it goes to a ice cube wich turns on the transformer for the servo amps. hitting e stop turns that transformer off.
[22:05:22] <alex_joni> sounds like amp enable to me
[22:05:43] <Gamma-X> pretty much but on the old control it had a label ( RESET ) haha
[22:05:43] <alex_joni> while you are in the state MACHINE_ON the amp enable is true
[22:05:59] <alex_joni> if you go to ESTOP or ESTOP_RESET then amp enable is false
[22:06:00] <Gamma-X> will it have continutity all the time though?
[22:06:23] <Gamma-X> the reset button that is?
[22:06:24] <alex_joni> if you connect the amp enable to a parport? pin, and from there to your transformer control, it will do what you want
[22:06:45] <alex_joni> Gamma-X: again, I don't know what your reset button is/does
[22:06:53] <Gamma-X> alex_joni i dont need the mesa cards tio putput any electric though.
[22:06:57] <alex_joni> I can only tell you what emc2 does or can do
[22:06:59] <jepler> that's a bit of a stretch
[22:07:37] <alex_joni> Gamma-X: you don't "need"?
[22:07:54] <jepler> e.g., we don't know if this "ice cube wich" will take a signal at parport current and voltage
[22:08:04] <alex_joni> the mesa card outputs are perfectly ok for driving small loads
[22:08:15] <alex_joni> jepler: sure.. that's for Gamma-X to figure out
[22:08:18] <jepler> we don't know what else should be involved in turning on or off this signal -- e.g., should it be involved in the estop chain, or just with the software "amplifier enable"?
[22:08:21] <alex_joni> voltage and current needed
[22:08:25] <Gamma-X> theres already current going through the reset switch
[22:08:25] <jepler> we don't know a lot of things
[22:08:27] <Gamma-X> 24v
[22:08:35] <jepler> don't hook 24V to your parport :-P
[22:08:41] <alex_joni> nor to your mesa
[22:08:45] <Gamma-X> when u touch the 2 together the machine turns on.
[22:08:53] <alex_joni> do you keep them touched?
[22:08:56] <Gamma-X> no
[22:09:12] <Gamma-X> it just allows the ice cube to switch on.
[22:09:12] <alex_joni> ok, so you probably have a latching relay in your "ice cube"
[22:09:17] <Gamma-X> correct
[22:09:20] <alex_joni> wth is an ice cube?
[22:09:37] <Gamma-X> sorry for a diff terminology
[22:09:41] <Gamma-X> an ice cube is a relay
[22:09:55] <alex_joni> Gamma-X: before messing with specifics like these, I would start designing my estop chain
[22:10:05] <Gamma-X> alex_joni I already have it setup
[22:10:13] <jepler> see you guys later
[22:10:18] <alex_joni> ok, mind to share how it connects to emc2?
[22:10:25] <alex_joni> see you jeff
[22:10:26] <Gamma-X> it will have a software e stop and a manual e stop, the machine has it built in.
[22:10:43] <alex_joni> built in => means nothing to me
[22:10:56] <Gamma-X> aslong as emc keeps the circuit closed the machine will stay on, once the circuit becomes open, then the servos power down,
[22:11:10] <alex_joni> ok, what else is on the circuit?
[22:11:17] <alex_joni> do you have pneumatics there?
[22:11:28] <alex_joni> is there a pressure switch?
[22:11:30] <Gamma-X> an estop button, and i will program the vfd in aswell
[22:11:34] <alex_joni> do you check for estop?
[22:11:37] <alex_joni> vfd?
[22:11:38] <alex_joni> lube?
[22:11:40] <alex_joni> etc..
[22:11:57] <Jymm> Espresso?
[22:12:02] <alex_joni> there are 2 circuits involving e-stop
[22:12:20] <alex_joni> the first one (the most important) is the one causing the machine to stop when somethings funny
[22:12:30] <alex_joni> the on you already have figured out
[22:12:54] <Gamma-X> if a limit switch is hit, it will shut the machine down. if i hit e stop, the machine shuts down.
[22:13:11] <Gamma-X> all im going to do is add in emc into the chain of the already existing estop.
[22:13:16] <alex_joni> 24V power, estop button, vfd, limit switches, emc driven relay -> machine power
[22:13:25] <alex_joni> Gamma-X: and that's quite fine
[22:13:39] <alex_joni> but you probably also want emc2 to know the estop has been tripped..
[22:13:41] <Gamma-X> correct
[22:13:52] <Gamma-X> u reffering to the manual switch?
[22:13:56] <Gamma-X> button*
[22:14:03] <alex_joni> button, vfd, limit, whatever
[22:14:23] <Jymm> BRB = Big Red Button, as I like to call it =)
[22:14:42] <Gamma-X> the vfd will talk to emc, and the button has 4 pins, im using the top 2 for manual estop and the bottom 2 to let emc know when i hit the button
[22:14:50] <Gamma-X> haha
[22:14:56] <alex_joni> Gamma-X: sounds crappy to me
[22:15:04] <Gamma-X> well what would u suggest?
[22:15:32] <alex_joni> Gamma-X: I would take the end of the estop chain (just before it commands the machine/servo power) and feed that as an input to emc2
[22:15:45] <alex_joni> probably through an optocoupler (because of voltage levels)
[22:15:55] <Gamma-X> ok
[22:15:55] <alex_joni> that way anything trips the estop chain, you see it
[22:16:04] <alex_joni> even if it's emc2 that tripped it
[22:16:04] <Jymm> s/you/emc/
[22:16:11] <alex_joni> Jymm: correct
[22:16:13] <Gamma-X> ill put it through the 7i37 then
[22:16:24] <Jymm> icky
[22:16:26] <alex_joni> I am usually assuming people are looking at emc when something doesn't work
[22:16:34] <alex_joni> Gamma-X: not through
[22:16:41] <Gamma-X> sorry
[22:16:43] <Gamma-X> in?
[22:16:47] <Gamma-X> connected
[22:16:48] <alex_joni> yes :)
[22:16:50] <Gamma-X> haha
[22:16:51] <Jymm> in between maybe
[22:16:57] <Gamma-X> i hate u guys hahaha
[22:17:06] <alex_joni> you simply "look" at the signal
[22:17:15] <alex_joni> don't divert/change/influence it in any way
[22:17:17] <Jymm> [emc] ---- [estop chain] --- [ I/O board ]
[22:17:30] <alex_joni> Jymm: not quite
[22:17:33] <Jymm> wait, I did that wrong
[22:18:01] <Jymm> fucking ascii grpahics on one-line in irc =)
[22:18:06] <alex_joni> [24V]---[estop-chain]--+--[servo power]
[22:18:14] <alex_joni> |- emc input
[22:18:24] <Jymm> alex_joni: cheater =)
[22:18:31] <alex_joni> add a couple of spaces in there :)
[22:18:54] <alex_joni> Gamma-X: estop is not something to treat lightly
[22:19:01] <alex_joni> hope you are aware of this
[22:19:15] <BigJohnT> I second that and put it withing reach!
[22:19:37] <Jymm> alex_joni: Hmmm, you know... if ther was a way to compressive short vector grphics via irc client, you could do simple graphics via one liners.
[22:19:45] <Gamma-X> alex_joni im aware, i just know that the estop circuit is already in place, i tested it with out a control box.
[22:19:54] <alex_joni> in europe we have regulations that each mushroom _must_ use both contacts
[22:20:02] <alex_joni> so you have 2 distinct circuits on machines
[22:20:15] <alex_joni> just for increased safety (redundancy)
[22:20:27] <alex_joni> Gamma-X: good to know
[22:20:41] <alex_joni> gene_: then you may proceed.. you have 1 question left
[22:20:46] <alex_joni> darn
[22:20:51] <alex_joni> gene_: then you may proceed.. you have 1 question left
[22:20:51] <Gamma-X> hahah i got one
[22:20:54] <Jymm> Gamma-X: with emc off and i/o card off ?
[22:20:54] <alex_joni> argh
[22:20:59] <alex_joni> can't type for shit
[22:21:02] <Gamma-X> Jymm correct
[22:21:12] <Jymm> alex_joni: That's ok, I speak typo
[22:21:23] <alex_joni> Jymm: surely he'll test again after everything is supposed to work
[22:21:23] <Gamma-X> Jymm reason being is i kept all circuits inside the original servo cabinet in tact,
[22:22:17] <Jymm> Gamma-X: Well, whatever you do, just remember the term is called FAIL ***SAFE***, not fail sorta kinda convientant safely
[22:23:25] <Gamma-X> i connect 2 pins.. little r and little s to be exact and then touched little e to little s and the machine booted up, i disconected the reset wich is the little e to little s and it still ran wich is good, then i disconnected the little r from little s and it shutdown, meaning the e stop circuit is already in place, now all i have to do is put my manual estop button in that circuit, and emc in that circuit.
[22:24:27] <alex_joni> sounds like e to s acts as machine on
[22:24:29] <Gamma-X> my question is, where on the mesa boards should I connect my " reset button" and my estop wires.
[22:24:36] <alex_joni> and r to s as estop.. or something
[22:24:36] <Gamma-X> alex_joni correct
[22:24:43] <Gamma-X> exactly
[22:24:54] <Gamma-X> and that was without a control of any type connected.
[22:24:59] <alex_joni> Gamma-X: you'll probably want an output triggering a relay which connects e to s
[22:25:26] <Gamma-X> why would u suggest that? theres already one inside the servo cabinet,
[22:25:41] <alex_joni> output from emc2 I meant
[22:25:53] <Gamma-X> alex_joni thats already in place.
[22:26:06] <alex_joni> then I don't understand what you're asking..
[22:26:40] <Gamma-X> alex_joni i just need to know what spot on the 7i33 can I plug in these 2 circuits that It will not add any voltage.
[22:26:59] <alex_joni> Gamma-X: then I suggest you read the 7i33 manual
[22:27:09] <alex_joni> I can't help with specifics/pins etc
[22:27:21] <alex_joni> like I said.. I can tell you about what emc2 is capable to do
[22:27:27] <Gamma-X> alex_joni I have but im confused on what is an IBIT and what is an OBIT
[22:27:31] <alex_joni> you need to figure out how to use that .. safely
[22:27:39] <alex_joni> IBIT sounds like input bit?
[22:28:08] <BigJohnT> Gamma-X you might need to isolate the machine circuits from the mesa card with relays...
[22:28:25] <alex_joni> or optos
[22:28:27] <Gamma-X> BigJohnT Its already been done.
[22:29:05] <alex_joni> Gamma-X: if you ask how to connect something, then it's not done
[22:29:32] <Gamma-X> well the question was specific to the mesa 7i33
[22:29:55] <Gamma-X> as far as I know there 2 different types of connections on that card,
[22:30:41] <alex_joni> types of connections?
[22:30:55] <alex_joni> I think you mean 3 different connectors
[22:31:17] <Gamma-X> The 7I37 provides 8
[22:31:17] <Gamma-X> Isolated 48VDC 1A output drivers and 16 Opto-isolated inputs.
[22:33:20] <alex_joni> inputs are IN0..IN15 (pins 1,3,5,7,...,31)
[22:33:38] <alex_joni> outputs are OUT0..OUT7 (pins 33,35,..,47)
[22:33:50] <alex_joni> Gamma-X: from the 7i37 manual
[22:34:09] <Gamma-X> im trying to figure out the pinout, .
[22:34:13] <Gamma-X> damn
[22:34:16] <Gamma-X> i jsut got it haha.
[22:34:34] <Gamma-X> im readin the silk screen on this board and it doesnt have I's or O's
[22:35:03] <Gamma-X> looks like that atleast,
[22:35:04] <alex_joni> Gamma-X: read the fine manual
[22:35:06] <Gamma-X> im an idiot...
[22:35:10] <alex_joni> page 6
[22:35:15] <Gamma-X> i did... pinout was wierd in my head my bad.
[22:35:44] <alex_joni> now you need to see if you connect that card to a port on the 5i20
[22:35:52] <alex_joni> and you need to see how those pins will match
[22:36:09] <Gamma-X> yeah i know.
[22:36:11] <alex_joni> (usually people connect the 5i20 and the 7i37 with a 50-pair ribbon)
[22:36:20] <alex_joni> that's generally a 1-1 mapping
[22:36:21] <Gamma-X> thats what i got.
[22:36:28] <Gamma-X> a scsi cable.
[22:36:41] <Gamma-X> 3 dollars for a scsi cable woohoo!
[22:36:47] <alex_joni> so.. open the 5i20 manual, look for pin 33 on port A|B|C
[22:36:57] <alex_joni> and see which one suits you :)
[22:37:07] <Gamma-X> ohhhhh
[22:37:08] <alex_joni> you probbaly will have a port for the servo card
[22:38:25] <Gamma-X> the 5i20 is just an i/o card, all ports on it are I or O
[22:39:12] <alex_joni> Gamma-X: yes.. and no :)
[22:39:27] <Gamma-X> heres an even better nube question, what would the outputs on the 7i37 be used for?
[22:39:29] <alex_joni> the pins on the ports also have some predefined function
[22:39:44] <alex_joni> spindle on? limit switches?
[22:39:52] <Gamma-X> is this according to emc?
[22:39:58] <Gamma-X> or mesa?
[22:40:12] <alex_joni> Gamma-X: lets step back a second
[22:40:18] <alex_joni> you have a 5i20.. right?
[22:40:31] <Gamma-X> yes
[22:40:39] <alex_joni> it has 3 connectors
[22:40:43] <Gamma-X> correct
[22:40:50] <alex_joni> and it can provide 72 I/Os
[22:41:03] <alex_joni> so either 72 Ins, or 72 Outs, or a combination
[22:41:04] <Gamma-X> correct
[22:41:26] <alex_joni> furthermore it can have some hardware program loaded in the fpga to make some pins work in a special way
[22:41:34] <alex_joni> for example encoder counters
[22:41:47] <Gamma-X> ok
[22:41:58] <Gamma-X> yeah i know that.
[22:42:03] <alex_joni> ok, that is done by loading a firmware into the card
[22:42:09] <alex_joni> the emc2 driver loads one
[22:42:14] <Gamma-X> a hal config right?
[22:42:22] <alex_joni> nope
[22:42:27] <Gamma-X> ahh
[22:42:39] <alex_joni> a card firmware (coniguring the FPGA on the card)
[22:42:40] <Gamma-X> i havnt gotten to hal yet hahaha,
[22:42:46] <alex_joni> right
[22:43:13] <alex_joni> that card config (called HOSTMOT4 or HOSTMOT8 or something like that) defines how the card is set up
[22:43:16] <alex_joni> internally
[22:43:20] <Gamma-X> ok
[22:43:35] <alex_joni> and how each of the pins on those 3 connectors are configured
[22:43:44] <alex_joni> either inputs or outputs or something more advanced
[22:44:14] <Gamma-X> well what are u trying to explain?
[22:44:40] <alex_joni> I'm trying to explain that if you want to use emc2 and it's driver and the fpga configuration loaded by it..
[22:44:52] <alex_joni> then you want to keep with the pinout assumed by the above
[22:45:14] <Gamma-X> i thought u editted that driver once u have everything hooked up.
[22:45:53] <alex_joni> you don't want to mess with the fpga firmware
[22:46:23] <Gamma-X> ok, where would I find the correct layout for the firmware?
[22:46:38] <alex_joni> Gamma-X: in the docs obviously
[22:46:40] <Gamma-X> alex_joni thanks for lettin me know by the way
[22:47:18] <alex_joni> http://www.linuxcnc.org/docview/2.2/html//hal_drivers.html#r1_5
[22:47:40] <alex_joni> Gamma-X: scroll down to connector pinout
[22:47:46] <BigJohnT> Gamma-X likes Molly Hatchet
[22:49:54] <alex_joni> Gamma-X: found it?
[22:50:11] <Gamma-X> yes
[22:50:21] <alex_joni> see P2?
[22:50:24] <Gamma-X> i have everything on the 7i33 connected the right way/
[22:50:35] <Gamma-X> the 7i37 seems it doesnt realy matter
[22:50:40] <alex_joni> you probably want the 7i33 connected to P2
[22:51:01] <alex_joni> the 7i37 goes to P3 or P4 depending what further things you need/don't need
[22:51:21] <Gamma-X> yup
[22:51:35] <alex_joni> i you want to count 4 axes encoders (maybe spindle speed or such), thne I'd put the 7i37 on P4
[22:51:51] <alex_joni> make that 5 axes
[22:52:31] <Gamma-X> so basicly i can connect the estop and servo start connections anywhere theres an input on the 7i37
[22:52:55] <Gamma-X> and just make sure i connect the 7i37 to p4
[22:53:20] <alex_joni> if you put it on P4 you'll be working with in-16..in-31
[22:53:26] <alex_joni> and out-08..out-15
[22:53:31] <alex_joni> in emc2/HAL that is
[22:54:03] <Gamma-X> ill be settin that up once i get the boards wired up.
[22:54:15] <Gamma-X> then my plan is to take a multi meter and test it all
[22:54:30] <Gamma-X> before i hook it up to the machine
[22:54:43] <Gamma-X> or use halscope
[22:55:31] <alex_joni> using halscope is for tweaking things
[22:55:48] <alex_joni> if something is wired incorrectly by the time you start halscope the magic smoke is long gone
[22:56:39] <Gamma-X> aslong as i hook up the 7i33 and the 7i37 to the 5i20 correctly i should have a problem because nothing will be attached just a big pin connector
[22:57:14] <alex_joni> right.. but if you feed 220V into the 7i37 it may damage the 7i37 and the 5i20
[22:57:37] <alex_joni> same goes for 7i33
[22:58:00] <alex_joni> wish I'd gotten the T version
[22:58:05] <Gamma-X> I here what ur sayin
[22:58:08] <Gamma-X> yeah t version is awsome
[22:58:15] <alex_joni> they didn't have them back then..
[22:58:51] <Gamma-X> but the cards are + 10 bucks each for the t and ontop of that 15 for each connector that 80 bucks just for the t versions
[22:59:24] <Gamma-X> its a good price to pay though compared to buy breakout boards
[22:59:32] <alex_joni> right
[22:59:50] <alex_joni> bob are 25-45$
[22:59:57] <alex_joni> http://www.daqstuff.com/50_pin_breakout_500013.htm
[23:00:10] <alex_joni> http://www.winfordeng.com/products/brk2x25.php
[23:00:38] <Gamma-X> dang
[23:01:29] <alex_joni> daqstuff messed their site
[23:02:27] <Gamma-X> hmmm
[23:02:28] <Gamma-X> what else...
[23:02:42] <Gamma-X> the only thing i need to know is the m codes from the original machine
[23:02:46] <alex_joni>
[23:02:47] <Gamma-X> for oil and coolant, etc
[23:03:21] <alex_joni> well.. I'm off to bed
[23:03:45] <Gamma-X> goodnight man good talkin to u
[23:04:35] <alex_joni> goodnight :)
[23:04:52] <alex_joni> hope it helped at least a bit
[23:05:09] <Gamma-X> yes sir
[23:05:55] <BigJohnT> Gamma you get the new computer loaded up with linux and emc?
[23:07:42] <Gamma-X> yes sir
[23:07:59] <BigJohnT> cool
[23:08:19] <Gamma-X> i got the 7i33 and 7i37 in my lap im wiring them up now to my 37 pin connector
[23:08:21] <BigJohnT> tack good notes and document everything
[23:08:28] <BigJohnT> take
[23:09:07] <Gamma-X> fuck that shit!
[23:09:19] <BigJohnT> why
[23:10:23] <Gamma-X> BigJohnT NO BALLS NO GLORY!
[23:10:42] <Gamma-X> i want to do this and then sell new controll systems pre maid for the crusader II system
[23:10:50] <BigJohnT> but I might have to do it someday!
[23:11:00] <Gamma-X> beats the hell outa 7500 bucks for a new anilam
[23:11:02] <Gamma-X> true u may
[23:11:08] <Gamma-X> but then ill help u
[23:11:13] <BigJohnT> ok
[23:11:52] <Gamma-X> and if anyone needs this information u can contact me ( this is for the logs baby) nygoldenmemories%yahoo!
[23:12:18] <BigJohnT> I bet you would have just as much fun with a new anilam but have less momey
[23:12:30] <Gamma-X> i know
[23:13:04] <Gamma-X> 7000 less hahaha
[23:14:23] <BigJohnT> just use the force and check twice before letting any magic smoke out
[23:16:07] <Gamma-X> so i heard
[23:16:22] <Gamma-X> how often do u here stories about smoke
[23:17:15] <BigJohnT> twice for each time
[23:19:09] <Gamma-X> lol
[23:25:19] <BigJohnT> http://i47.photobucket.com/albums/f163/johnplctech/Plasma%20Cutter/Plasma007.jpg
[23:25:37] <cradek> that's quite the transformer
[23:28:56] <BigJohnT> 600 watt 56v
[23:29:06] <BigJohnT> antec
[23:29:24] <BigJohnT> + 12vdc reg and 5vdc reg
[23:29:47] <Gamma-X> damn! lol
[23:41:19] <Gamma-X> u cant do a latency test until everything is hooked up right>?
[23:41:35] <BigJohnT> no
[23:41:51] <BigJohnT> you don't need anything hooked up
[23:42:06] <BigJohnT> and you don't want emc running
[23:42:23] <skunkworks> with version 2.2.2 you can run latency-test from terminal
[23:46:28] <BigJohnT> different from before?
[23:47:54] <skunkworks> before you did this http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting#RTAI_Latency_test
[23:49:29] <skunkworks> (still can)
[23:51:48] <BigJohnT> yes that is what I did
[23:52:58] <BigJohnT> which is what is still in the integrater manual
[23:53:11] <BigJohnT> ?
[23:54:13] <Gamma-X> skunkworks well what do u do now?
[23:54:56] <Gamma-X> how do i configure my 5i20 and 7i33 and 7i37 cards for what I have put into them?
[23:56:09] <BigJohnT> http://www.linuxcnc.org/docview/html//config_stepconf.html#sec:Latency-Test
[23:57:56] <BigJohnT> Gamma-X: type latency-test in a terminal window
[23:58:22] <Gamma-X> ok
[23:58:26] <Gamma-X> ill try it now hold on
[23:58:30] <Gamma-X> whats a good number?
[23:59:38] <BigJohnT> lower is faster
[23:59:56] <BigJohnT> these numbers look different than the other test...
