[00:00:31] <Gevallen_Engel> do you just need more tension?
[00:01:06] <Jymmm> Not more, just some. This isn't standard off the shelf but custom made.
[00:01:34] <Gevallen_Engel> You could set it up like a bow saw
[00:01:53] <Jymmm> Can't, needs to be electrically isolated
[00:02:20] <Jymmm> and it's such a small area; making it even more difficult
[00:02:29] <Tom_itx> ceramic insulators

[00:02:49] <Jymmm> Tom_itx: Too big (I have some)
[00:02:56] <Tom_itx> small ones
[00:03:11] <Jymmm> these actually are small, just not small enough.
[00:06:50] <Jymmm> I'm already using 4-40 screws as it is.
[00:06:58] <Gevallen_Engel> Arent the actual ones just fiberglass and the wire itself?
[00:07:49] <Jymmm> "ones" ?
[00:07:57] <Gevallen_Engel> sealing elements
[00:08:25] <Jymmm> heh, not that I know of. fiberglass uses resin and the resin isn't temp safe
[00:08:46] <Jymmm> but some use teflon cloth
[00:09:52] <Gevallen_Engel> they dont seem terribly priced on fleabay, in a variety of sizes
[00:10:52] <Jymmm> I dont need the heating element, I have that already. I need a way to TENSION it as it stretches when heated to 1200F
[00:11:09] <Jymmm> which is far above what those impulse sealers typcally go
[00:12:06] <Tom_itx> does it retract when it cools again?
[00:12:16] <Jymmm> yeah
[00:12:20] <Gevallen_Engel> what I was getting at is you might need to find a way to fit your element to a hard form rather than tensioning it
[00:12:26] <Tom_itx> what about mica insulators
[00:12:49] <Tom_itx> you asked about that a few weeks back
[00:13:16] <Jymmm> sure, that was a different one, this one is far smaller
[00:13:33] <Tom_itx> just how small?
[00:13:50] <Jymmm> 0.040"
[00:14:09] <Tom_itx> the heating element is .040 long?
[00:14:30] <Tom_itx> or that's the diameter
[00:14:45] <Jymmm> thickness of the itme being sealed
[00:14:58] <Gevallen_Engel> how wide is it
[00:15:25] <Jymmm> 1.25"
[00:15:52] <Tom_itx> what percentage of stretch?
[00:17:03] <Jymmm> about 1/4 to 3/8" or so

[00:39:04] <Tom_itx> what have ppl found to be good connectors for steppers?
[00:39:21] <jdh> 4pin plug thingies
[00:39:29] <Jymmm> cb mic jacks
[00:39:37] <Tom_itx> i'm about fed up with these original ones i'm stuck with
[00:40:04] <jdh> why are you stuck with anything
[00:40:19] <Jymmm> Tom_itx: http://www.universal-radio.com/catalog/parts/micconn.html
[00:40:28] <Tom_itx> well originally i was trying to maintain backward compatibility with my old control
[00:40:45] <Jymmm> Tom_itx: they are also twist lock
[00:40:58] <Tom_itx> so i got a few housings and a couple bags of pins

[00:41:14] <taiden> hey Tom_itx
[00:41:32] <jdh> http://tinyurl.com/6wftsuz
[00:41:56] <taiden> i'm going to make a softjaw arrangement
[00:42:09] <taiden> any tips before i do that?
[00:42:10] <Tom_itx> jdh i saw a similar setup
[00:42:27] <Tom_itx> taiden what do you have for clamping?
[00:42:34] <taiden> i was going to make something up
[00:42:44] <Tom_itx> make one side rigid to the table
[00:42:51] <taiden> two pieces of mdf
[00:42:56] <taiden> one bolted to the table
[00:43:12] <taiden> the other being pushed by 3/8" bolt tapped into angle iron which is bolted to the table
[00:43:23] <Tom_itx> keep the other one from raising up when you clamp it
[00:43:31] <taiden> that's my main concern
[00:43:55] <Tom_itx> so make a guide for it
[00:46:40] <Tom_itx> my control box isn't attached to the mill is the issue

[01:08:49] <taiden> so i take it that i should home the machine, pick easy coordinates and then cut the soft jaws, and use those locations for part centers after that?

[01:47:01] <r00t4rd3d> bought
[01:47:53] <r00t4rd3d> thats a good price for supported rails
[01:48:01] <r00t4rd3d> with pillows
[01:48:23] <r00t4rd3d> how do you cut those?
[01:49:09] <r00t4rd3d> i was thinking a crack whore and her one good tooth but i am not sure...
[01:49:43] <Tom_itx> cutoff wheel
[01:49:48] <Tom_itx> if they are hardened
[01:49:54] <r00t4rd3d> really?
[01:50:00] <Tom_itx> i would
[01:50:08] <Tom_itx> but i'd remove the slides first
[01:50:11] <r00t4rd3d> on a angle grinder?
[01:50:26] <Tom_itx> don't get them hot
[01:50:38] <r00t4rd3d> what if im bothered?
[01:51:40] <r00t4rd3d> im probably just take them to the local metal guy
[01:51:46] <Tom_itx> why do you want to cut them anyway?
[01:51:52] <r00t4rd3d> he has a power hack saw
[01:52:00] <r00t4rd3d> 1/2 too long
[01:52:03] <Tom_itx> pfft
[01:52:06] <Tom_itx> live with it
[01:52:14] <r00t4rd3d> fuck that
[01:52:21] <r00t4rd3d> i would have to reconfig everything
[01:52:37] <Tom_itx> so cut them off then
[01:52:55] <r00t4rd3d> i was just thinkging if i could do it
[01:52:56] <Tom_itx> if it's a hardened shaft he may not want to cut them with his power hack saw
[01:53:04] <Tom_itx> i would but that's me
[01:53:06] <r00t4rd3d> torch them then
[01:53:17] <Tom_itx> not aluminum
[01:53:24] <Tom_itx> and not precision bars
[01:53:33] <Tom_itx> unless you just don't care
[01:53:39] <r00t4rd3d> your nick should be rain.
[01:53:53] <Gevallen_Engel> a chop saw?
[01:54:03] <Gevallen_Engel> with something to keep it cool
[01:54:09] <Tom_itx> i would but with a cutoff wheel
[01:54:14] <r00t4rd3d> ive thought about a diamond blade in a chop saw
[01:54:24] -!- uuyhy [uuyhy!4fb3d12f@gateway/web/freenode/ip.] has joined #linuxcnc
[01:54:25] <Gevallen_Engel> less control with a grinder
[01:54:30] <uuyhy> hii all
[01:54:34] <r00t4rd3d> i could file it
[01:54:36] <Tom_itx> you don't need a diamond blade unless you just want to spend the bucks for one
[01:54:44] <Tom_itx> you could chew it too
[01:54:48] <r00t4rd3d> the last 1 inch or so dont really matter
[01:54:49] <Gevallen_Engel> a large band saw would work too
[01:54:52] <r00t4rd3d> will be out of bounds
[01:55:04] <r00t4rd3d> i have a large band saw
[01:55:08] <uuyhy> i'm back to here after 2 years...
[01:55:09] <r00t4rd3d> but it dont like metal
[01:55:14] <Tom_itx> so make your stuff a half inch longer
[01:55:20] <r00t4rd3d> dude
[01:55:21] <Tom_itx> and leave them alone
[01:55:37] <r00t4rd3d> you would have to see my design
[01:55:42] <Tom_itx> i would?
[01:55:54] <r00t4rd3d> http://www.cnczone.com/forums/diy-cnc_router_table_machines/152794-mdf_madness-3.html
[01:56:17] <r00t4rd3d> to make my Y axis one mm longer would soil my sack.
[01:56:53] <r00t4rd3d> i could pad it out but them i lose stability.
[01:56:58] <r00t4rd3d> then*
[01:58:06] <uuyhy> I'm tried to connect my nachin to the EMC2 but the stepper motor conlroller need to get UP stepping /DOWN stepping, but the EMC2 send me STEPPING / DIRECION
[01:58:45] <uuyhy> how i can change the way that it work?
[01:58:46] <r00t4rd3d> what controller?
[01:59:14] <uuyhy> somthing that i build years... ago..
[01:59:19] <r00t4rd3d> and its probably in your Parallel Settings
[01:59:58] <uuyhy> it based on 74193 and 74139 and L293
[02:01:00] <uuyhy> it work good in 2009
[02:01:27] <uuyhy> this is the video from 2009 www.youtube.com/watch?v=MA_kd_3oM3k

[02:06:20] <uuyhy> what do you think about this machin? http://www.ebay.com/itm/4axis-CNC-Router-6040-220V-110V-DRILLING-MILLING-engraving-mahcine-/220946046100?pt=LH_DefaultDomain_0&hash=item3371691c94
[02:06:49] <r00t4rd3d> ill build it for you for 800
[02:06:54] <Tom_itx> expensive
[02:06:57] <r00t4rd3d> thats what i think
[02:07:01] <Gevallen_Engel> ohh
[02:07:03] <r00t4rd3d> store, brb
[02:07:04] <Gevallen_Engel> that reminds me
[02:07:34] <uuyhy> how you get the linear rails?
[02:08:07] <Gevallen_Engel> http://tinyurl.com/dyhl97q
[02:08:24] <Gevallen_Engel> I picked that up awhile ago, I was thinking it looked like it had potential?
[02:10:11] <uuyhy> what is that machin?
[02:10:26] <Tom_itx> it may but i'm not sure either what it is for
[02:10:39] <Gevallen_Engel> I have no idea
[02:10:52] <Tom_itx> maybe some type of measuring equipment?
[02:11:00] <Gevallen_Engel> the guy at the surplus store it was at said it had something to do with ic manufacturing
[02:11:14] <Gevallen_Engel> checking levelness but that didnt seem to make sense
[02:13:12] <uuyhy> what is the langth of the rails..
[02:13:47] <uuyhy> i want something about A3 paper size..

[11:06:52] <jthornton> you can read it too
[11:07:09] <jthornton> uuyhy, so you found the correct file and have made your changes?
[11:09:26] <uuyhy> jthornton: i see the my-mill.ini here /home/cnc/emc2/configs/my-mill/my-mill.ini
[11:10:03] <uuyhy> i open it with gedit...
[11:10:19] <jthornton> what version are you running?
[11:10:54] <uuyhy> how i check it?
[11:11:52] <jthornton> top bar in the Axis GUI has the version like "AXIS 2.x.x ..."
[11:12:09] <jthornton> I'm guessing 2.4
[11:12:35] <uuyhy> 2.3.0
[11:12:53] <jthornton> you really need to upgrade
[11:13:13] <jthornton> in any case the file you need to edit is my-mill.hal
[11:14:19] <uuyhy> but i download the 10.04 from the cnclinux site yesterday
[11:14:51] -!- sumpfralle has quit [Quit: Leaving.]
[11:14:57] <jthornton> that should be 2.5

[11:18:25] <uuyhy> i need to do onle the link with the 2.5
[11:18:41] <uuyhy> or also the first link with the 2.4?
[11:29:30] <JT-Shop> LOL, it's been a long time since I've seen a dumb question
[11:31:51] <uuyhy> JT-Shop: ?
[11:33:02] <JT-Shop> why would someone post two links if they wanted you to ignore one?
[11:36:51] <uuyhy> maybe i can go directly to 2.5..
[11:38:26] <uuyhy> this is fresh install.. maybe it simple to install ubuntu 10.04 with 2.5 version..
[11:38:39] <uuyhy> there is a iso like that?
[11:40:23] <uuyhy> or I have to make the upgrade from 2.3 (my problem is P3 computer and i cant connect it to my network, i dont have dungel, and i dont have LAN card)
[11:41:22] <JT-Shop> http://linuxcnc.org/index.php/english/download/21?task=view
[11:42:01] <JT-Shop> 2.3 has never been on 10.04 iirc so I'm confused how you got 2.3
[11:42:57] <JT-Shop> 2.3 is only on 8.04 Hardy
[11:43:11] <uuyhy> i download from the same link...
[11:43:41] <JT-Shop> what part of the world are you in?
[11:44:18] <uuyhy> NY and Israel

[13:26:00] <Tom_itx> JT-Shop, maybe the confusion is not with you
[13:27:00] <Tom_itx> i'm confused though
[13:28:04] <Tom_itx> i'm using my mpg single ended t the 7i47 with a resistor divider on the other leg of the input and that worked fine before but now i get no input to the board. i tested the mpg with a LA and it's working
[13:28:39] <Tom_itx> maybe i need to adjust the voltage divider since it's 5v powered now instead of USB. that shouldn't matter though since they're both 5v
[13:29:00] <Tom_itx> all the other inputs work fine
[13:29:32] <Tom_itx> no led blinkage on the 7i47 inputs for it
[13:30:09] <Tom_itx> checked dmesg to make sure the config was right

[14:39:57] <pcw_home> Tuipveus: as a master maybe as a slave, no
[14:41:24] <Tom_itx> pcw_home while back you suggested using a voltage divider for the differential inputs to the 7i47, do you recall the recomended values?
[14:41:29] <Tom_itx> or voltage
[14:41:41] <Tom_itx> i'm not getting signal on my MPG now
[14:41:49] <Tom_itx> i tested the MPG with a LA
[14:42:07] <pcw_home> What is your MPG output voltage
[14:42:11] <Tom_itx> i could rewire it differential to try
[14:42:13] <Tom_itx> 5v
[14:42:40] <Tom_itx> the leds on the 7i47 don't blink
[14:42:46] <pcw_home> then a 2.5 V threshold would be the best noise immunity wise
[14:42:56] <Tom_itx> i'll check it in a little bit
[14:43:26] -!- BenceKovi11 [BenceKovi11!~BenceKovi@catv-89-132-134-30.catv.broadband.hu] has joined #linuxcnc
[14:43:31] <pcw_home> so a voltage divider with 2 equal resistors from 5V to Gnd (say 100 Ohm x2)
[14:44:00] <Tom_itx> are the inputs to the 7i47 3.3v?
[14:44:19] <pcw_home> they are 200 mv to 25V
[14:44:31] <Tom_itx> i did rewire the box but the only real change was to switch from USB power to a 5v smps
[14:44:59] <Tom_itx> 100 ohm isn't too 'strong' ?
[14:45:13] <Tom_itx> i'll check what i used when i measure it again
[14:45:43] <Tom_itx> it's the only thing i can think of as to why it's not giving me a signal
[14:45:49] <pcw_home> easy to check, just put your voltmeter across the differential inputs
[14:45:51] <pcw_home> you should get +2.5V in one state and -2.5 in the other if not you have a wiring error
[14:46:15] <Tom_itx> the led used to blink though
[14:46:18] <Tom_itx> and it's not now
[14:46:42] <Tom_itx> i'll check it in a bit...
[14:46:44] <pcw_home> (100 is fine even 10 is fine with a power resistor)
[14:46:59] <Tom_itx> trying to clear off my desk here first
[14:49:05] <pcw_home> I would use a divider on the lower end if one divider is used for a bunch of inputs
[14:49:07] <pcw_home> also forgetting to remove the termination on any input used this way will cause trouble
[14:49:08] <pcw_home> (as you will put current into you divider center leg)
[14:49:31] <Tom_itx> no, these were working before
[14:49:57] <Tom_itx> i think that one has a single divider on it
[14:50:05] <Tom_itx> i share some on some switches

[16:20:39] <FinboySlick> r00t4rd3d: OK, I was thinking that it could be a somewhat clever way to implement a z axis.
[16:20:55] <r00t4rd3d> its threaded per say
[16:20:56] <FinboySlick> Though then you have to deal with twisting wires or what not.
[16:21:47] <r00t4rd3d> just raising and lowering it would not get that much twisting i dont think
[16:22:29] <r00t4rd3d> right now my router does not move up or down more then a inch
[16:23:57] <FinboySlick> That doesn't answer a much deeper and life-altering question however.

[16:24:56] <ReadError> put a dial on it
[16:25:06] <r00t4rd3d> nope
[16:25:07] <ReadError> then figure out how many 0.0001 steps it takes to reverse back
[16:25:53] <r00t4rd3d> i dont think i have any backlash
[16:26:00] <FinboySlick> ReadError: Making the steps too small might introduce more error if his steppers can't match them.
[16:26:13] <FinboySlick> No?
[16:26:25] <ReadError> FinboySlick: idk, i was able to hit 0.0001 * 10
[16:26:32] <ReadError> and it hit 0.001 perfect on the dial
[16:26:47] <r00t4rd3d> backlash would cause errors in my cuts right?
[16:27:13] <ReadError> yea you will lose accuracy every time the motor changes directions
[16:27:14] <FinboySlick> r00t4rd3d: 0.001" backlash you likely couldn't see in wood.
[16:27:45] <Tom_itx> does backlash compensation do a pretty good job of fixing that?
[16:27:51] <r00t4rd3d> i dont have any proper clamps yet either, i just hold it down with my hands
[16:27:55] <ReadError> Tom_itx: seems so for me
[16:27:58] <ReadError> i set it
[16:28:04] <ReadError> then i can hit left/right once
[16:28:06] <ReadError> and it moves
[16:28:13] <ReadError> rather than having that deadband

[18:59:43] <mrsun> aluminium is harder
[18:59:44] <mrsun> hmm
[18:59:50] <FinboySlick> mrsun: I'd say it's mor brittle...
[18:59:55] <mrsun> i wonder why they have magnesium for hot printing on like leather etc ?
[19:00:50] <A0Sheds> probably an alloy
[19:02:54] <Kentan> Any likely problem when the machine is not finding the same position again after moving around when it seams to manage to do that in mach3 ?
[19:03:28] <anonimasu> how high did you set your accel?
[19:03:37] <anonimasu> higher then when running mach3 ?
[19:04:30] <Kentan> quite sure its lots lower, and the machine is running lots slower in linuxcnc
[19:07:21] <Kentan> 20 mm/s^2 in linuxcnc and 200 mm/s^2 in mach3 (those are the values in the boxes not sure that they actually mean what I believe)

[19:28:23] <pcw_home> wrong direction setup or direction hold times or wrong step len/polarity can all cause missed/wrong steps
[19:33:22] <kentan> How do one convert mach3's Step Pulse (2us) and Dir Pulse (0) to linuxcncs values ? I guessed at 2000 ns step time 3000 ns step space, diection hold and setup both at 2500 ns

[20:15:08] <mrsun> with ballscrews with the high leads i guess its not that hard to get high speeds

[22:00:12] <Tuipveus> I don't have rpi yet... It will come in couple of weeks
[22:00:47] <Tuipveus> pcw_home: ethercat-master is fine, I can buy beckhoff slave-terminal
[22:03:52] <Tuipveus> I am familiar with some of the beckhoff-devices since I work as a robot programmer... I also have used Linux many years... But I am not familiar with putting these two things together.
[22:04:16] <Tuipveus> Any help, links etc. greatly appreciated...
[22:04:47] <anonimasu> only one axis left :)
[22:05:04] <Tuipveus> I don't know much about c-programming, just some basics
[22:05:44] <Tuipveus> is there any commandlineinterface to "talk" directly with the beckhoff-slaves?
[22:05:49] <anonimasu> mrsun: small steppers, for servos you can get whatever rpm
[22:05:58] <anonimasu> mrsun: my big 1.9kw servos run up to 5k rpm
[22:07:05] <anonimasu> mrsun: one point to note is that about 5mm pitched screws are what most machines use, both for strength and also they come in whatever backslash grade you want smaller screws are a bit more limited and also a shitload of cash.
[22:08:39] * anonimasu draws up a ball puller for the nc lathe
[22:10:42] <Tuipveus> so are guys (and girls) building everything from scratch like in Terminator movie, or are you using some industrial controllers with the cnc?
[22:12:38] <anonimasu> i do both
[22:12:58] <anonimasu> tho mainly i use industrial iron, coupled with homebrew bits and pieces
[22:13:17] <anonimasu> and also, i have some real machines of my own for actually making stuff on :p(atm)
[22:14:43] <Tuipveus> I just found this: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Etherlab and I was wondering if I can do the same
[22:15:09] <anonimasu> I have 80 pieces left of a 120 piece run and cycletime is 20 seconds so I gotta make my machine feed itself bars
[22:16:26] <Tuipveus> :)
[22:17:03] <Tuipveus> about 30 minutes left, that is not bad
[22:18:08] <anonimasu> that means pulling a new piece of stock out every 20 seconds
[22:18:22] <anonimasu> opening and closing the spindle and doors to the machine
[22:19:17] <anonimasu> with a drill holder and a floating tap holder cycletime would be about 35 seconds probably and they would fall off done for cleaning
[22:19:40] <anonimasu> and pulling bars out i could have a 30 minute coffee break and swap tools in the mill
[22:19:46] <anonimasu> :p
[22:21:37] <Tuipveus> I have played mostly with Kuka-robots which have vxworks realtime operating system over the windows...
[22:25:48] <anonimasu> also i predict repeat stuff so i better get shit running on auto
[22:31:36] <anonimasu> nice stuff
[22:31:53] <anonimasu> i play with iec-61131 everyday at work pretty much when im not busy manufacuring things

[23:54:07] <skunkworks__> might have been less.
[23:54:26] <skunkworks__> works though
[23:54:35] <Tom_itx> i'm not getting any leds on the mesa card like i was though
[23:54:58] <Tom_itx> i could wire up the differential side and try that
[23:55:12] <Tom_itx> it's got a resistor divider on it right now
