[00:05:00] <JT-Shop> Jymmm: I've used all mine up mounting different stuff
[00:05:11] <andypugh> I want this lathe, but I don't want it _now_
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=280640435673
[00:05:16] <JT-Shop> yea, so I'll make 18" of them
[00:05:26] <Jymmm> JT-Shop: Hit any repair shop, they have buckets of em
[00:05:48] <JT-Shop> there ain't no repair shops in down town Poplar Bluff :P
[00:05:49] <Jymmm> but I guess you're bored
[00:06:25] <Jymmm> http://www.evilmadscientist.com/article.php/hershey
[00:06:50] <JT-Shop> andypugh: looks like a sturdy one
[00:07:28] <JT-Shop> hmmm slant bed
[00:07:30] <andypugh> Very nice lathe, also with a covered leadscrew and the slant bed _probably_ means space for an X-servo.
[00:08:08] <JT-Shop> just have a few glasses of wine and keep flea bay up on your computer and it will be yours
[00:10:15] <andypugh> It is also 270 miles away, and I don't have space in the garage for it.
[00:10:34] <JT-Shop> 270 miles is not far around here
[00:10:47] <andypugh> I think it is quite a big variant of the breed, 6'4" long and 32" deep.
[00:11:42] <JT-Shop> I don't have any space in my garage either
[00:13:52] <andypugh> I suppose I could move house...
[00:14:47] <andypugh> I think the second one here is a shorter version

[00:15:51] <JT-Shop> the tractor sure, the backhoe (digger) now
[00:16:00] <andypugh> Yes, but if I built anything that size I would have to seize next-doors garden as well as my own.
[00:16:23] <Jymmm> andypugh: and your point is?
[00:16:24] <JT-Shop> that does become a problem
[00:16:34] <atmega> you could take a little each year

[00:17:03] <andypugh> I want their garage, actually. Then I could build a workshop on the side.

[00:19:16] <JT-Shop> I have a Samson manual lathe at the other shop
http://i47.photobucket.com/albums/f163/johnplctech/Machine%20Shop/HPIM2631.jpg
[00:19:21] <andypugh> I have the middle garden and the middle garage. (behind the black car). If I had the westerly garage I could have a linked workshop (you can't really see the northern pitch of the garage roofs)
[00:19:53] <andypugh> Looks very modern.
[00:20:42] <JT-Shop> yea, 70-80's I guess
[00:21:16] <JT-Shop> I don't use it much since I got the CHNC
[00:21:48] <Tom_itx> send it over here
[00:21:56] <Jymmm> I've always wanted a shop big enough to drive thru in a motorhome/bus with dual doors
[00:21:58] <JT-Shop> pretty good photo
[00:22:30] <JT-Shop> I'm moving it over to my new shop, it does come in handy with a tail stock

[00:38:25] <danimal_garage> i need a newer one myself
[00:38:46] <danimal_garage> one like that would be good, is it 14x46ish?
[00:39:12] <Jymmm> JT-Shop: for what?
[00:39:18] <danimal_garage> something like 16x36 would be awesome, but hard to find
[00:39:25] <JT-Shop> to get started on your new shop
[00:39:52] <Jymmm> JT-Shop: a screwgun, welder, or trowel, but never a hammer
[00:40:18] <JT-Shop> yea Dan it is about 14 x 42
[00:40:29] <danimal_garage> thats what mine is
[00:40:37] <danimal_garage> good size
[00:40:48] <danimal_garage> i just want a heavier duty one
[00:41:12] <JT-Shop> I need to rework the cross slide and the compound slide as they are a bit loose
[00:43:11] <danimal_garage> finish the roof?
[00:45:13] <JT-Shop> up to the ridge caps but it rained all day today
[00:45:42] <JT-Shop> I have enough overlap that it is water tight from that angle
[00:47:26] <danimal_garage> cool

[11:38:46] <archivist> HDB10, you would paste a link so we dont need to hunt
[11:39:12] <HDB10_> It's at the top of the list
[11:39:51] <archivist> no it is not
[11:40:57] <HDB10_> pastebin has not sent a response for some reason maybe a search
[11:41:07] <HDB10_> simple loop
[11:41:27] <archivist> what is so hard about pasting the unique url to your paste
[11:42:42] <HDB10_> I haven't used the system very much and Iam just getting into using it.
[11:43:16] <archivist> there are hundreds of pastes after yours
[11:44:01] <archivist> look at your url bar in your browser, it should point at your paste

[12:12:00] <HDB10_> mhaberler : I don't know if it will work as I am looking for a edge trigger and I am not homing the axis
[12:12:42] <cpresser_> in fact, there is an edge-detect-component

[12:20:59] <HDB10_> mhaberler: How do you increment the A axis at the same time ?
[12:21:18] <mhaberler> are you in manual, mdi or auto mode?
[12:21:32] <HDB10_> Auto
[12:22:05] <HDB10_> Actually running the program
[12:22:17] <mhaberler> what exactly are you trying to do? have A move and wait until switch triggers?
[12:22:56] <mhaberler> then stop move? if so, try a probe (g38.x)
[12:24:46] <HDB10_> I'll try to explain it. I have a disk on the A axis and it has a slot in it. The issue is that the position from the home position varies by several degrees.
[12:25:02] <mhaberler> ok
[12:25:05] -!-
i_tarzan has quit [Ping timeout: 246 seconds]
[12:26:31] <HDB10_> So I wish to detect the start of the slot and the second side of the slot and the slot width can vary a few degrees also ...
[12:26:56] <HDB10_> This is the best way to explain it to you.
[12:27:17] <mhaberler> and you have a switch to detect the start and 'the second side'
[12:27:21] <jthornton> probe input
[12:27:24] <mhaberler> yep
[12:28:01] <mhaberler> fine, so why dont you probe with g38 then?
[12:28:05] <HDB10_> I have a photo cell and it is connected to a specific pin and is test and working.
[12:28:28] <mhaberler> good, or it with the probe input then
[12:29:21] <mhaberler> g38 can probe any axis, including a
[12:29:53] <HDB10_> I have tried this and it what to reverse the A axis and I need to have it advance.
[12:30:11] <HDB10_> I have spent days on it.
[12:30:30] <mhaberler> I dont get 'want to reverse'
[12:30:43] <mhaberler> g38 stops on probe contact
[12:31:58] <mhaberler> you can probe in either direction - put in relative mode (g91), then G38.x A<distance> where distance is positive or negative
[12:32:02] <HDB10_> Doesn't it store and return to the start again ?
[12:32:07] <mhaberler> NO
[12:32:13] <HDB10_> OK
[12:32:18] <mhaberler> the manual is VERY clear
[12:32:35] <mhaberler> The move stops (within machine acceleration limits) when the programmed point is reached, or when the requested change in the probe input takes place.

[13:55:52] <skunkworks> http://groups.yahoo.com/group/mach1mach2cnc/message/126126
[13:55:58] <mhaberler> parts are coming together - the state save/restore and introspection stuff was the last major thing I needed for the toolchange-in-gcode although its useful well beyond that
[13:56:41] <mhaberler> a minor bit is missing, namely interaction of M7x save/restore and abort handling, that's needed for toolchange
[13:56:51] <mhaberler> the major thing is proper docs..
[13:57:40] <mhaberler> right now any mode the TC gcode subs change is reflected in the main programs mode and that's not acceptable
[13:59:26] <skunkworks> neat

[15:05:12] <mhaberler> sure
[15:09:18] <JT-Shop> power up, home, and right back to making 6-32 standoffs, I love EMC2!
[15:10:46] <skunkworks> I agree!
[15:11:14] <atmega> why does one make 6-32 stand offs instead of getting them from china?
[15:12:45] <cradek> JT-Shop: I made some 4-40 ones - I form tapped them, which worked really great
[15:13:06] <skunkworks> I have not form tapped yet.
[15:13:32] <cradek> my limited experience says for blind holes it can't be beat
[15:14:06] <JT-Shop> I want them today
[15:14:07] <cradek> you have to get the hole size very right - for small holes I hear sometimes people ream them
[15:14:35] <cradek> (I just drilled for mine)
[15:14:36] <skunkworks> lots of lube
[15:15:00] <cradek> yeah, the lathe has cutting oil flood
[15:15:02] <JT-Shop> I'm missing 3 standoffs to install a new motherboard so it is much faster to just make them and much more fun
[15:15:28] <atmega> that's a good reason :)
[15:15:40] * JT-Shop wonders if he will rigid tap the hole or chicken out and hand tap them
[15:15:42] <atmega> I have hundreds of them here
[15:15:59] <skunkworks> doesn't everyone have a box of extra computer screws/hardware?

[15:28:15] <atmega> me too... I also can't imagine voluntarily going to ann arbor
[15:28:16] <JT-Shop> just need to finish up some wiring to test it out
[15:30:40] <atmega> looks good to me
[15:31:43] <atmega> I don't recall doing SPI that way though (SPI.transfer)
[15:32:23] <JT-Shop> seems like there is several ways to do it
[15:32:45] <JT-Shop> SPI.transfer uses the hardware SPI AFAIK
[15:33:22] <atmega> I was reading a multichannel ADC, seems like I had to tell it to start the conversion, wait for a bit, then tell it what channel I wanted to read
[15:33:41] <atmega> but, I might be confusing that with something else
[15:34:26] <JT-Shop> the Max6675 is a send data only chip
[15:34:54] <pcw_home> You often start a conversion and then select the _next_ channel to read
[15:35:04] <atmega> yeah, I just don't remember the .transfer
[15:36:15] <JT-Shop> http://www.arduino.cc/playground/Code/Spi
[15:37:57] <JT-Shop> http://arduino.cc/en/Reference/SPI
[15:41:59] <JT-Shop> took me a while to understand that the SPI.transfer you had to send something to get something even if the slave device only sends data out :)
[15:43:48] <atmega> I think I must have been doing SPI by hand
[15:44:02] <skunkworks> btw - turning off accelleration in the flash settings - fixed the problem.
[15:45:38] <JT-Shop> for some reason unknown to me I wanted to use the hardware SPI on the ATmega328 :)

[15:47:34] <atmega> I got some niftier i2c ADC's with built in programmable amps and used those with the WIRE library instead.
[16:00:52] <JT-Shop> cool, I needed either thermistors or thermocouples that are encased in SS for my project
[16:01:20] <JT-Shop> i have some i2c stuff somewhere
[16:03:12] <Jymmm> Is SPI, hw many masters can there be?
[16:03:16] <Jymmm> how
[16:03:37] <Jymmm> In SPI, how many masters can there be?
[16:03:39] <cpresser_> one.
[16:03:58] <JT-Shop> 1
[16:04:00] <Jymmm> so its a star topology?
[16:04:59] <cpresser_> no, chain
[16:05:17] <cpresser_> daisy-chain. one chip after another
[16:05:17] <Jymmm> then there can be more than one master, just not at the same time
[16:05:53] <cpresser_> depends on the output-drivers on the clock-line
[16:06:51] <Jymmm> from JT-Shop link...
[16:07:00] <Jymmm> It can also be used for communication between two microcontrollers.
[16:07:00] <Jymmm> With an SPI connection there is always one master device (usually a microcontroller) which controls the peripheral devices.
[16:07:00] <Jymmm>
[16:09:15] <cpresser_> I2C can have multiple masters, since all lines are active low and the output-drivers are open-collector. so you dont have drivers fighting against each other.
[16:09:44] <Jymmm> I2C is cool, everything has an address
[16:10:20] <mozmck_work1> in SPI, don't you have to have one chip-select line per slave? That would limit the practical number of devices I would think.
[16:10:49] <Jymmm> http://www.evilmadscientist.com/article.php/hershey
[16:11:12] <JT-Shop> yes, but you can multiplex the chip select lines
[16:12:44] <cpresser_> not all chips have a chip/slave-select line. for example the TI5925 (LED-Driver) has none
[16:13:18] <cpresser_> it is always possible to have a clever design with a multiplex to adress more chips :)
[16:14:19] <pcw_home> I prefer SPI since its easier to isolate and can be much faster that I2C
[16:16:02] * Jymmm kicks cpresser_ in the shin for giving a LED driver he can't use
[16:19:29] <L84Supper> Jymmm: how large an area can you laser engrave?

[16:21:14] <Jymmm> L84Supper: Like what?
[16:21:34] <L84Supper> Jymmm: sheet of cold roll or aluminum
[16:22:08] <Jymmm> L84Supper: I have a CO2 laser, not a YaG laser. Doesn't do metal.

[16:34:32] <Jymmm> 6.35mm
[16:34:49] <Jymmm> 25.4/4
[16:35:07] <atmega> how fast can you cut 1/4"?
[16:35:12] <Jymmm> slow
[16:35:28] <L84Supper> atmega: can you make your 4mm acrylic 2.35mm thicker, then he can cut it
[16:36:15] <Jymmm> This is 1/4"

[16:38:38] <L84Supper> Jymmm: I was wondering if your machine can handle a sign project where the material is 24" x 24" 16Ga painted steel and we'd like to laser etch an image through the paint layer down to the steel
[16:39:00] <Jymmm> L84Supper: I'd need to see the drawing
[16:39:33] <L84Supper> it's line art or a 1 bit bitmap
[16:39:43] <Jymmm> L84Supper: I'd still need to see the drawing
[16:40:39] <Jymmm> L84Supper: it's all about registration and complexity.
[16:44:14] <L84Supper> Jymmm: I'll get back to you soon with one
[16:44:22] <Jymmm> L84Supper: ok
[16:46:18] <L84Supper> the Cermark looks interesting.... does it contain a frit that gets sintered by the laser?

[17:17:55] <cradek> do you have a community college where you can take "Lathe 1" and "Milling Machine 1"?
[17:18:19] <cradek> cad and cam don't make parts, machinists do -- that's what I did when I wanted to be able to actually make things
[17:18:31] <atmega> sadly for me, cad + cam will not make you a machinist.

WalterN [WalterN!~walter@tiwake.com] has joined #emc
[20:15:12] <cpresser_> may there be a problem with the way i load the component? i was running emc with the default-emc-start-script (as user cv), then load my component via halcmd as root
[20:15:31] <cradek> you should not do anything as root
[20:15:36] <danimal_garage> cradek, did you want me to look at anything in emc for you regarding the jogging in mdi issue?
[20:15:38] <cradek> but I doubt that's the problem
[20:16:36] <cradek> danimal_garage: yes, it would be great if you could say how to reproduce the problem (well, better yet, tell the devel list, since I probably am not the one to fix it)
[20:17:06] <cpresser_> since i was suspecting hardware-issues (its DIY), and replugged the device several times; so i was running it as root to avoid credential-problems
[20:17:30] <danimal_garage> cradek, i dont know if i can, it wont do it again after i went back to f3 then f5
[20:17:42] <cradek> fooey
[20:17:45] <danimal_garage> i had to run parts :\
[20:18:00] <skunkworks> I think seb fixed some things recently...
[20:19:04] <danimal_garage> cradek, i could home and touch off in mdi as well
[20:19:31] <cradek> true did you ever say what version you have?
[20:19:43] <cpresser_> cradek: shame on me. loading it as user 'cv' (the one running emc) solves the problem
[20:19:51] <danimal_garage> also another possible bug is that you can run a program in mdi if you right click and hit run from here
[20:19:57] <cradek> relevant things have been "adjusted" recently
[20:20:35] <cradek> cpresser_: weird
[20:20:36] <danimal_garage> cradek, i have 2.5 but if you need any more info than that you'll have to tell me where to look for it
[20:21:18] <cradek> ummmmm, have you remembered yet how you got that version? :-)
[20:22:09] <danimal_garage> it was the buildbot page
[20:22:22] <cradek> then try dpkg -l emc2
[20:22:42] <danimal_garage> in terminal?
[20:22:55] <cradek> yes
[20:23:03] <danimal_garage> wont scre anything up or shut down emc, right? stupid question but i gotta ask
[20:23:08] <danimal_garage> screw
[20:23:08] <cradek> no
[20:23:11] <danimal_garage> ok
[20:23:53] <danimal_garage> ok i did that
[20:24:03] <cpresser_> cradek: segfault is gone, but it is not working.. but so far, i am not out of clues...
[20:24:18] <danimal_garage> says unknown package -1
[20:24:21] <anonimasu> does anyone have a clue if the mesa 7i40 will work togther with the 7i43?
[20:24:31] <seb_kuzminsky> danimal_garage: i had some surprise jogs in mdi as well recently
[20:24:43] <cradek> danimal_garage: l, not 1
[20:24:49] <danimal_garage> Ha! see it aint just me
[20:24:54] <seb_kuzminsky> jeff fixed one bug, but i think there is at least one still lurking in 2.4 and 2.5 (and master)

[20:25:37] <seb_kuzminsky> up until a few weeks or so ago, i could jog in MDI mode (f5) by hitting Ctrl-Shift-Arrows
[20:25:39] <seb_kuzminsky> jeff fixed that
[20:25:49] <danimal_garage> do i have to do sudo?
[20:26:08] <seb_kuzminsky> a few days ago i could jog in MDI mode by hitting F5, then F4, then arrow keys (iirc)
[20:26:16] <seb_kuzminsky> danimal_garage: no sudo needed for that
[20:26:20] <danimal_garage> it says i cant do it without superuser privilege
[20:26:26] <seb_kuzminsky> run "dpkg -l emc2 | grep Version"

[20:28:26] <seb_kuzminsky> perfect
[20:28:32] <seb_kuzminsky> you're using buildbot debs from the master branch
[20:28:45] <seb_kuzminsky> those should have jeff's Ctrl-Shift-Arrow fix

motioncontrol has quit [Remote host closed the connection]
[20:29:12] <anonimasu> and the next question is what kind of mesa io module do you use for buttons?
[20:29:19] <seb_kuzminsky> was it F5, then F4, then arrow keys? I think that's what i did the other day
[20:29:43] <seb_kuzminsky> anonimasu: i use a 7i37COM for the buttons on my control panel
[20:29:52] <cradek> yeah 7i37 is nice for that
[20:30:03] <anonimasu> easy to wire?
[20:30:04] <cradek> or whatever you use for the rest of your IO
[20:30:05] <danimal_garage> i dont usually use yeystrokes to go to mdi so i probably just hit the mdi tab
[20:30:16] <anonimasu> any idea about the 7i40 servo driver?
[20:30:17] <danimal_garage> keystrokes
[20:30:22] <cradek> mine has a bunch of opto22 for IO
[20:31:15] <anonimasu> is it really nescessary to have that if you spec sensors for 5v output?
[20:31:46] <cradek> are you talking about sensors or buttons?
[20:32:09] <anonimasu> well, limit switches
[20:32:17] <anonimasu> will the 7i37com-ta do that nicely?
[20:32:32] <cradek> seb_kuzminsky: what's com?
[20:32:41] <danimal_garage> seb_kuzminsky, you are right, f4 does make it so you can jog
[20:33:16] <anonimasu> common input reference
[20:33:20] <seb_kuzminsky> cradek: that's the new version where all the inputs share a common low side
[20:33:27] <danimal_garage> i was in mdi then i hit f4 then f5 and you can do everything you can do in manual control
[20:33:27] <seb_kuzminsky> makes wiring a little more convenient
[20:33:31] <cradek> ah
[20:33:38] <seb_kuzminsky> danimal_garage: surprise!! movement!!
[20:33:41] <cradek> yes if all your sensors are the same
[20:34:01] <danimal_garage> however i'm positive i didnt hit f4 the first time it happened
[20:34:07] <seb_kuzminsky> ruh-roh
[20:34:11] <anonimasu> mhm, I think I'll go for the 7i37-ta
[20:34:13] <cradek> so far I always seem to end up with half of them needing high common and the other half low common
[20:34:17] <anonimasu> since that has output drives
[20:34:19] <danimal_garage> i've actually never seven seen that screen before
[20:34:21] <anonimasu> for some aux stuff
[20:34:39] <seb_kuzminsky> anonimasu: the 7i37com has the same outputs as the regular 7i37, iirc
[20:35:17] <anonimasu> im kindof lost as to which one is better
[20:35:54] <anonimasu> my ground will be common anyway
[20:36:34] <seb_kuzminsky> if all your inputs are high-side switched and have common ground, i think the 7i37com is more convenient to wire up
[20:36:36] <cradek> seb_kuzminsky: do you still have that crazy override limit I wired up, that you have to be behind the machine to activate?
[20:36:40] <anonimasu> even for the inductive sensors...
[20:37:01] <seb_kuzminsky> the regular 7i37 is more flexible, at the cost of having to run more wires
[20:37:09] <seb_kuzminsky> cradek: yes, it's saved me more than once :-)
[20:37:31] <seb_kuzminsky> it's good calisthenics to reach that button and hit the right jog key in axis :-)
[20:37:39] <cradek> heh
[20:37:44] <cradek> super convenient
[20:38:02] <anonimasu> I can just bridge all commons.. what I will use as well
[20:38:05] <anonimasu> on the normal one
[20:38:24] <anonimasu> is there a output like ref on it?

[20:56:57] <atmega> no pullups needed on?
[20:57:53] <andypugh> There are weak ones (I think) built in. Pete would know better than me. I am just saying what I have got away with.
[20:58:02] <PCW> Pull ups are provided on the card (most cards) or the FPGA (7I43)
[20:58:08] <atmega> cool
[20:58:29] <atmega> I would have bought some, but it is 2011 in the rest of the world :)
[20:59:57] <anonimasu> really nice, that's the way im going to do it...
[21:00:37] <PCW> If you use the bare FPGA pins beware of hot plugging things or make sure you alaway have a ground between systems that you do not disconnect
[21:00:46] <PCW> always
[21:01:00] <anonimasu> tho, I dont plan on that since
[21:01:12] <anonimasu> I like screw terminals and more robust stuff
[21:01:21] <anonimasu> I already killed a 7i43 before without even using it
[21:02:14] <cradek> 7i37 is only $69
[21:02:17] <anonimasu> PCW: what card do you recommend for general purpose io? the regular 7i37 or the com one?
[21:02:30] <cradek> fpga cards are much more expensive to risk
[21:02:53] <Tom_itx> hey anonimasu
[21:03:08] <anonimasu> Tom_itx: hey!
[21:03:14] <cradek> hm $79 for screws
[21:03:19] <PCW> Weve killed a few using cell phone chargers as power supplies (Ive measured about 70V open circuit from charger ground lead to earth)
[21:03:25] <cradek> guess that is getting up there
[21:03:51] <anonimasu> this was using usb from the computer as power and it just died for some reason
[21:03:53] <PCW> If you just want 5V IO you can use a 7I42TA
[21:03:55] <cradek> weird - I assumed those chargers always gave isolation, but maybe not.
[21:04:32] <Tom_itx> anonimasu, how did you kill a 7i43?
[21:04:35] <cradek> ahh 7i42ta looks great (and cheap)
[21:04:47] <anonimasu> Tom_itx: I dont know, I think static electricity and bad luck...
[21:04:56] <PCW> well they are isolated but have considerable capacitance to the primary side

[21:29:37] <Tom_L> which encoder?
[21:29:51] <Tom_L> C C4 or CR
[21:30:59] <anonimasu> the r35 one

[22:42:17] <danimal_garage> this is getting expensive :(
[22:45:41] <skunkworks> what do you mean 'positioniing error'?
[22:46:01] <danimal_garage> it looses position
[22:46:06] <andypugh> Wierd.
[22:46:10] <danimal_garage> doesnt actually throw an error code
[22:46:16] <danimal_garage> yea
[22:46:35] <skunkworks> so - your encoder couting is getting lost?
[22:47:08] <danimal_garage> yea
[22:47:23] <andypugh> FWIW my completed machine is running without the SMI patch (it disappears every time you recompile) so gives a RTAI delay every 64 seconds. (Of course, only the first is reported) and it does not actually cause any problems.
[22:47:59] <danimal_garage> it goes resolver===>drive to convert to encoder counter===>7i37
[22:48:33] <danimal_garage> or 7i33
[22:48:58] <danimal_garage> whichever one is the daughter board for 4 servos

[22:49:18] <danimal_garage> andypugh, i don't have SMI on my machine
[22:49:50] <andypugh> No, I am just saying that the problem is likely to be unrelated to the realtime delays (it was you with that problem with a screensaver?)

[22:51:14] <skunkworks> danimal_garage: are you still getting realtime delays
[22:51:18] <danimal_garage> i get it in the neighborhood of 750k

[22:51:39] <danimal_garage> skunkworks, havent seen one since i turned off the screensaver
[22:51:41] <danimal_garage> yes
[22:51:49] <skunkworks> thats good.
[22:51:54] <danimal_garage> yea
[22:51:55] <andypugh> Wierd, no sign of that with mine (so far)
[22:52:00] <skunkworks> how far from your drives to the 7i33?
[22:52:06] <skunkworks> is it differental or ttl?
[22:52:13] <danimal_garage> i turned the screensaver, but i leave it blank instead of the cosmos thing

[22:52:50] <danimal_garage> i turned back on the screensaver*
[22:53:04] <skunkworks> can you compare the counts in the drive to the counts in emc?
[22:53:06] <danimal_garage> i'm using cat6 cable, sheilded and stranded
[22:53:28] <danimal_garage> i dunno
[22:53:29] <skunkworks> figure out if you are loosing between mesa and the drives or the drives and the reslovers?

[22:53:51] <danimal_garage> i dont see how it can be the resolvers as they dont count
[22:54:05] <danimal_garage> but i have limited knowledge so anything is possible
[22:54:25] <skunkworks> how far is your position off?
[22:54:55] <skunkworks> and do you have the 7i33 set for differential?

[22:55:40] <danimal_garage> it varies. about .100" this last time, but it continually changes. it is set to differential
[23:01:07] <skunkworks> exactly .1?
[23:01:17] <skunkworks> what is 1 rotation of your resolver?
[23:02:35] <danimal_garage> no, there's no consistent error
[23:02:42] <danimal_garage> .200"
[23:03:10] <danimal_garage> it goes off a little bit more every time i feed it
[23:05:53] <anonimasu> PCW: are you still there?
[23:06:03] <anonimasu> PCW: how well does your plasma thc work?
[23:06:13] <andypugh> danimal_garage: Resolver loose on shaft?
[23:07:00] <danimal_garage> i'll check
[23:07:18] <PCW> anonimasu: Its just a isolated noise resistant A-D that outputs frequency
[23:07:26] <andypugh> Is it always the same axis that glitches?
[23:07:33] <Tom_L> anonimasu
[23:07:55] <danimal_garage> andypugh, right now, yes, but not before
[23:08:14] <PCW> ( 2500V isolation ~1pf capacitance from input to output)
[23:08:28] <andypugh> Never discount the possibility of multiple problems...
[23:09:37] <PCW> multiple overlapping problems is often the case for hard to solve bugs
[23:11:07] <danimal_garage> swapping the drive now

[23:11:29] <danimal_garage> i have a spare
[23:11:52] <PCW> I would expect noise in the resolver leads to be more of an issue than the encoder leads (depending on how good the drives resolver to digital converter is)
[23:13:38] <JT-Shop> chance of snow tonight :/
[23:14:20] <Tom_L> and 70 F tomorrow
[23:15:47] <danimal_garage> PCW, i just don't see how a resolver can be off like that. i can see it being off while moving or if it's a full rev off, but not staying in the incorrect position by a random amount
[23:15:58] <danimal_garage> am i wrong on that?
[23:18:01] <PCW> Depends on how they do the resolver to incremental (quadrature) converter...

[23:18:35] <danimal_garage> the only computer in here with a serial port died
[23:19:11] <PCW> USB-Serial
[23:19:48] <danimal_garage> think that will work?
[23:20:09] <PCW> They seem OK with our serial stuff

[23:23:19] <kirk_wallace> I am trying to make && make install using this Makefile:
http://wiki.linuxcnc.org/uploads/Makefile , but I get a message "Makefile:24: .o/homann_modio.d: No such file or directory". I made a mistake the first time I compiled but removed all of the new files and tried again, but make seems to be remembering something from the previous make.
[23:23:40] <JT-Shop> make clean?
[23:23:55] <kirk_wallace> Okay. I'll try.
[23:24:20] <kirk_wallace> Nope, I get the same message
[23:24:26] <danimal_garage> JT-Shop, i have one but i dont have a driver for it
[23:25:18] <danimal_garage> win 7 doesnt have one in it either
[23:25:31] <danimal_garage> i dont know what brand it is
[23:26:19] <danimal_garage> yay win update found one
[23:32:57] <kirk_wallace> In the Makefile there is a my_file.d , what are .d files?
[23:35:33] <andypugh> Directories, often
[23:37:14] <kirk_wallace> I guess I could open one to see. Thanks.
[23:38:10] <kirk_wallace> Yup, directories. Now I'll check if they are correct.

[23:49:27] <JT-Shop> cool
[23:52:03] <danimal_garage> interesting... i turned on the overtemp monitoring and it instantly threw a motor over temp alarm
[23:52:31] <andypugh> Odd.
[23:52:41] <danimal_garage> maybe it's overheating
[23:53:02] <danimal_garage> but that doesnt explain the positioning error i guess
[23:53:07] <andypugh> No chance that one of the signal lines is accidentally wired through the thermistor? That might work OK until the motor heated up...
[23:53:53] <danimal_garage> i doubt it, they're all factory cables
[23:55:42] <danimal_garage> i'm dry running a part now
[23:55:47] <danimal_garage> we'll see how it works
[23:55:59] <danimal_garage> it's possible these motors dont have an OT sensor
[23:56:07] <PCW> An overheated motor would be stinking hot, is it to hot to touch?
[23:56:12] <danimal_garage> actually there's no wiring for one
[23:56:28] <danimal_garage> PCW, it's room temp
[23:56:41] <danimal_garage> as are the drives
[23:56:57] <danimal_garage> drives may be 1 or 2 deg warmer
[23:57:12] <PCW> You really have to push a servo system to get the motors hot
[23:57:17] <danimal_garage> yea
[23:57:26] <danimal_garage> i've never felt them get warm
[23:57:48] <danimal_garage> we'll see how it is now with the different drive
[23:58:30] <PCW> Do you have a scope?
[23:58:40] <danimal_garage> nope
