[01:54:11] <mrsun> hmm i need to make tapered stock for using when building foundry patterns =)
[01:54:28] <mrsun> that is like 5mm thick tapered pieces that i can just cut and glue on for ribs etc
[01:54:53] <syyl> hi mrsun :D
[01:54:56] <syyl> https://dl.dropbox.com/u/24396704/IMG_0635.jpg
[02:00:46] <mrsun> think im gonna start casting on my pcb milling machine =)
[02:00:51] <mrsun> or atleast making some patterns
[02:07:36] <syyl> good idea :=)
[02:07:47] <syyl> so
[02:07:54] <syyl> heading for muellernick ;)
[02:11:07] <mrsun> =)
[02:11:35] <mrsun> expensive to build machines tho, even tho i can make the castings myself ... linear guides etc costs alot :/
[02:12:01] <mrsun> even more nice patterns, nice syyl =)
[02:13:54] <mrsun> http://www.ebay.com/itm/New-2020-3D-Mini-CNC-Router-Drilling-Milling-Machine-Engraver-PCB-Engraving-/110905221036?_trksid=p4340.m1850&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D11%26meid%3D271108593919892700%26pid%3D100011%26prg%3D1005%26rk%3D1%26#ht_10603wt_1274 thinking that type of machine realy =)
[02:14:04] <mrsun> quite simple, and quite enginious :P
[02:15:46] <mrsun> those supported shafts, how are they fitted to the supports ?
[02:15:47] <mrsun> bolts ?
[02:31:59] <mrsun> omg
[02:32:09] <mrsun> £13 per 100mm of supported round rail :P
[02:32:58] <Jymmm> that's per 1.00mm, not 100mm =)
[04:13:09] <DJ9DJ> moin
[05:04:44] <uuyhy> hii all
[05:27:09] <uuyhy> someone here?
[05:39:04] <jthornton> at least one
[05:39:14] <jthornton> but it's mighty early
[05:42:41] <uuyhy> how i find the stepgen configuration file.. or how i set "type 1" mode in stepgen?
[05:44:15] <jthornton> did you create a configuration with the stepconf wizard?
[05:47:48] <jthornton> http://linuxcnc.org/docs/html/hal/rtcomps.html#_stepgen_a_id_sec_stepgen_a
[05:51:22] <r00t4rd3d> http://www.colonialmedical.com/flat-d-flatulence-deoderizer-P-1004.html
[05:52:27] <r00t4rd3d> by that for your gf/wife on your next anniversary.
[05:52:52] <uuyhy> yes i made it,
[05:53:10] <uuyhy> r00t4rd3d: I'm the wife...
[05:54:15] <r00t4rd3d> on your desktop
[05:54:24] <uuyhy> if i reamember right i need to edit some file..
[05:54:28] <jthornton> uuyhy, what version of the software are you using?
[05:54:33] <r00t4rd3d> there is a folder, My Mill or something
[05:54:41] <uuyhy> the 10.04
[05:54:52] <r00t4rd3d> then in that folder there is my_mill.ini
[05:55:10] <r00t4rd3d> that ini file is what you want to edit
[05:55:51] <jthornton> actually it won't be in the ini file
[05:57:12] <r00t4rd3d> yeah also i am a newb, I know where the config file is but not sure you can do what you want with it :)
[05:57:57] <r00t4rd3d> wood!
[05:58:15] <uuyhy> i see the file
[05:58:15] <Loetmichel> mornin'
[05:58:27] <jthornton> morning
[05:58:39] <r00t4rd3d> uuyhy, what exactly are you trying to accomplish?
[06:01:15] <uuyhy> r00t4rd3d: i try to set this type of configuration http://linuxcnc.org/docs/html/hal/images/freqgen-block-diag.png (the up down configuration)
[06:06:03] <uuyhy> the irc stop working..
[06:06:36] <uuyhy> r00t4rd3d: you see the pic that i send?
[06:14:39] <jthornton> r00t4rd3d, you got a couple of minutes to read something?
[06:14:51] <jthornton> http://gnipsel.com/linuxcnc/tutorial/gen02.html
[06:16:10] <uuyhy> r00t4rd3d: my firefox / irc get freezed.. - you get my pic?
[06:17:23] <uuyhy> jthornton: the link is for me?
[06:17:35] <jthornton> you can read it too
[06:17:52] <jthornton> uuyhy, so you found the correct file and have made your changes?
[06:20:09] <uuyhy> jthornton: i see the my-mill.ini here /home/cnc/emc2/configs/my-mill/my-mill.ini
[06:20:46] <uuyhy> i open it with gedit...
[06:21:02] <jthornton> what version are you running?
[06:21:37] <uuyhy> how i check it?
[06:22:35] <jthornton> top bar in the Axis GUI has the version like "AXIS 2.x.x ..."
[06:22:52] <jthornton> I'm guessing 2.4
[06:23:19] <uuyhy> 2.3.0
[06:23:37] <jthornton> you really need to upgrade
[06:23:57] <jthornton> in any case the file you need to edit is my-mill.hal
[06:25:03] <uuyhy> but i download the 10.04 from the cnclinux site yesterday
[06:25:41] <jthornton> that should be 2.5
[06:25:47] <uuyhy> how i upgrade it?
[06:26:18] <jthornton> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.4
[06:26:37] <jthornton> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.5
[06:29:08] <uuyhy> i need to do onle the link with the 2.5
[06:29:24] <uuyhy> or also the first link with the 2.4?
[06:40:14] <JT-Shop> LOL, it's been a long time since I've seen a dumb question
[06:42:34] <uuyhy> JT-Shop: ?
[06:43:45] <JT-Shop> why would someone post two links if they wanted you to ignore one?
[06:47:34] <uuyhy> maybe i can go directly to 2.5..
[06:49:09] <uuyhy> this is fresh install.. maybe it simple to install ubuntu 10.04 with 2.5 version..
[06:49:22] <uuyhy> there is a iso like that?
[06:51:06] <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)
[06:52:05] <JT-Shop> http://linuxcnc.org/index.php/english/download/21?task=view
[06:52:44] <JT-Shop> 2.3 has never been on 10.04 iirc so I'm confused how you got 2.3
[06:53:40] <JT-Shop> 2.3 is only on 8.04 Hardy
[06:53:54] <uuyhy> i download from the same link...
[06:54:24] <JT-Shop> what part of the world are you in?
[06:55:02] <uuyhy> NY and Israel
[06:55:16] <JT-Shop> New York now?
[06:55:51] <uuyhy> Israel..
[06:56:08] <JT-Shop> let me get the EU link for you
[06:56:15] <JT-Shop> http://dsplabs.upt.ro/~juve/emc/
[06:56:40] <JT-Shop> that is the 2.5 LinuxCNC on Ubuntu 10.04
[06:58:56] <uuyhy> i download it now..
[06:59:48] <uuyhy> in 20 minutes it will be done.
[07:00:17] <JT-Shop> YEA!
[07:13:23] <uuyhy> DONE! i go to bern it..
[07:28:15] <r00t4rd3d> im gonna bern one too!
[08:36:43] <Tom_itx> JT-Shop, maybe the confusion is not with you
[08:37:44] <Tom_itx> i'm confused though
[08:38:48] <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
[08:39:22] <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
[08:39:43] <Tom_itx> all the other inputs work fine
[08:40:15] <Tom_itx> no led blinkage on the 7i47 inputs for it
[08:40:52] <Tom_itx> checked dmesg to make sure the config was right
[08:48:08] <taiden> looks like in the middle of the night i bought a bosch 1617evs
[09:06:13] <Tuipveus> hello
[09:07:22] <Tuipveus> I was wondering, if I could connect my Raspberry Pi to Beckhoff with ethercat and do some simple io...
[09:16:14] <taiden> how do you like your rpi?
[09:50:41] <pcw_home> Tuipveus: as a master maybe as a slave, no
[09:52:07] <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?
[09:52:12] <Tom_itx> or voltage
[09:52:25] <Tom_itx> i'm not getting signal on my MPG now
[09:52:32] <Tom_itx> i tested the MPG with a LA
[09:52:50] <pcw_home> What is your MPG output voltage
[09:52:55] <Tom_itx> i could rewire it differential to try
[09:52:56] <Tom_itx> 5v
[09:53:24] <Tom_itx> the leds on the 7i47 don't blink
[09:53:29] <pcw_home> then a 2.5 V threshold would be the best noise immunity wise
[09:53:39] <Tom_itx> i'll check it in a little bit
[09:54:15] <pcw_home> so a voltage divider with 2 equal resistors from 5V to Gnd (say 100 Ohm x2)
[09:54:44] <Tom_itx> are the inputs to the 7i47 3.3v?
[09:55:02] <pcw_home> they are 200 mv to 25V
[09:55:14] <Tom_itx> i did rewire the box but the only real change was to switch from USB power to a 5v smps
[09:55:43] <Tom_itx> 100 ohm isn't too 'strong' ?
[09:55:57] <Tom_itx> i'll check what i used when i measure it again
[09:56:26] <Tom_itx> it's the only thing i can think of as to why it's not giving me a signal
[09:56:32] <pcw_home> easy to check, just put your voltmeter across the differential inputs
[09:56:34] <pcw_home> you should get +2.5V in one state and -2.5 in the other if not you have a wiring error
[09:56:58] <Tom_itx> the led used to blink though
[09:57:01] <Tom_itx> and it's not now
[09:57:25] <Tom_itx> i'll check it in a bit...
[09:57:27] <pcw_home> (100 is fine even 10 is fine with a power resistor)
[09:57:42] <Tom_itx> trying to clear off my desk here first
[09:59:48] <pcw_home> I would use a divider on the lower end if one divider is used for a bunch of inputs
[09:59:50] <pcw_home> also forgetting to remove the termination on any input used this way will cause trouble
[09:59:52] <pcw_home> (as you will put current into you divider center leg)
[10:00:14] <Tom_itx> no, these were working before
[10:00:40] <Tom_itx> i think that one has a single divider on it
[10:00:48] <Tom_itx> i share some on some switches

[11:26:03] <FinboySlick> r00t4rd3d: Artsy.
[11:28:43] <r00t4rd3d> i love f-engrave app :)
[11:29:38] <FinboySlick> r00t4rd3d: What's that helix around your spindle head?
[11:29:59] <r00t4rd3d> just part of the router
[11:30:24] <r00t4rd3d> http://www.cnczone.com/forums/showthread.php?p=1134651#post1134651
[11:30:27] <r00t4rd3d> post #30
[11:31:23] <FinboySlick> r00t4rd3d: OK, I was thinking that it could be a somewhat clever way to implement a z axis.
[11:31:38] <r00t4rd3d> its threaded per say
[11:31:39] <FinboySlick> Though then you have to deal with twisting wires or what not.
[11:32:31] <r00t4rd3d> just raising and lowering it would not get that much twisting i dont think
[11:33:12] <r00t4rd3d> right now my router does not move up or down more then a inch
[11:34:40] <FinboySlick> That doesn't answer a much deeper and life-altering question however.
[11:35:01] <FinboySlick> Do I make steak or spaghetti?
[11:35:07] <r00t4rd3d> steak
[11:35:08] <ReadError> r00t4rd3d: did you setup backlash ?
[11:35:12] <r00t4rd3d> no
[11:35:21] <FinboySlick> r00t4rd3d: Thanks ;)
[11:35:23] <r00t4rd3d> well the jitter test thing?
[11:35:36] <ReadError> no you like run it 1 way
[11:35:39] <ReadError> put a dial on it
[11:35:50] <r00t4rd3d> nope
[11:35:50] <ReadError> then figure out how many 0.0001 steps it takes to reverse back
[11:36:37] <r00t4rd3d> i dont think i have any backlash
[11:36:44] <FinboySlick> ReadError: Making the steps too small might introduce more error if his steppers can't match them.
[11:36:56] <FinboySlick> No?
[11:37:08] <ReadError> FinboySlick: idk, i was able to hit 0.0001 * 10
[11:37:15] <ReadError> and it hit 0.001 perfect on the dial
[11:37:31] <r00t4rd3d> backlash would cause errors in my cuts right?
[11:37:56] <ReadError> yea you will lose accuracy every time the motor changes directions
[11:37:57] <FinboySlick> r00t4rd3d: 0.001" backlash you likely couldn't see in wood.
[11:38:28] <Tom_itx> does backlash compensation do a pretty good job of fixing that?
[11:38:34] <r00t4rd3d> i dont have any proper clamps yet either, i just hold it down with my hands
[11:38:39] <ReadError> Tom_itx: seems so for me
[11:38:41] <ReadError> i set it
[11:38:47] <ReadError> then i can hit left/right once
[11:38:49] <ReadError> and it moves
[11:38:56] <ReadError> rather than having that deadband
[11:38:57] <Tom_itx> i need to measure mine once i button up the wiring
[11:39:32] <r00t4rd3d> im using antibacklash nuts on everything but my z axis
[11:40:30] <r00t4rd3d> well one is a antiback lash with a spring on it and the other is a Delarian(sp) nut...
[11:40:53] <ReadError> http://www.youtube.com/watch?v=lunksapjAEI
[11:40:55] <ReadError> ahahahha i need
[11:42:54] <FinboySlick> I really like the confused look when he sits on the axis and just looks at it swing.
[11:42:59] <Tom_itx> it would be a curious poll to do here as to how many in here use linuxcnc for pure hobby as to pure work
[11:43:27] <r00t4rd3d> what kinda bit work best on inlays?
[11:58:28] <Tom_itx> http://www.ebay.com/itm/10-PCB-router-engraver-engraving-tool-blade-cutter-bits-/160593156364?pt=LH_DefaultDomain_0&hash=item256419190c

[12:10:01] <Tom_itx> boarder is one that stays with you
[12:10:39] <IchGuckLive> KostgƤnger yes it eats alot
[12:10:48] <Tom_itx> probably near 106F here today (again)
[12:11:25] <IchGuckLive> we expect the hevyest thunderstorm for month with a 20degC drop in 1hour
[12:12:26] <Tom_itx> i like when that happens
[12:12:54] <Tom_itx> but when it does we usually get this: http://tom-itx.dyndns.org:81/~webpage/temp/hail/hail5.jpg

[13:54:28] <r00t4rd3d> in saudi arabia the pot is so good it will get you stoned.
[13:55:04] <ReadError> lol
[13:55:59] <r00t4rd3d> read you ever try the f-engrave program?
[13:56:45] <ReadError> nah
[13:56:50] <r00t4rd3d> http://home.comcast.net/~sskroch/Fengrave/fengrave.html
[13:56:57] <r00t4rd3d> its great for text

[13:57:22] <r00t4rd3d> its my new best friend
[13:57:28] <r00t4rd3d> i shot my dog
[13:59:10] <Tom_itx> may your dog come back as a bear and eat you
[14:07:41] <FinboySlick> r00t4rd3d: Was that a literal statement or an expression that I'm not familiar with?
[14:09:43] <mrsun> hmm is magnesium harder then aluminium ?
[14:10:27] <mrsun> aluminium is harder
[14:10:28] <mrsun> hmm
[14:10:33] <FinboySlick> mrsun: I'd say it's mor brittle...
[14:10:39] <mrsun> i wonder why they have magnesium for hot printing on like leather etc ?
[14:11:34] <A0Sheds> probably an alloy
[14:13:38] <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 ?
[14:14:11] <anonimasu> how high did you set your accel?
[14:14:20] <anonimasu> higher then when running mach3 ?
[14:15:13] <Kentan> quite sure its lots lower, and the machine is running lots slower in linuxcnc
[14:18:05] <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)
[14:39:06] <pcw_home> wrong direction setup or direction hold times or wrong step len/polarity can all cause missed/wrong steps
[14:44:06] <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
[14:54:02] <mrsun> hmm, what is a "diamond drag" ?
[15:25:07] <mrsun> hmm, ballscrews, linear guides, and way overpowered motors that is upgeared, could make a mean fast beast? :P (for engraving :P )
[15:25:32] <mrsun> tho smaller motors can run at higher rpms right ?
[15:25:51] <mrsun> with ballscrews with the high leads i guess its not that hard to get high speeds
[15:58:09] <DJ9DJ> gn8

[16:41:52] <archivist> oops
[16:43:52] <Jymmm> Talk about sweeping it under the rug
[16:45:33] <archivist> is there concrete/rock under the carpet
[17:10:56] <Tuipveus> I don't have rpi yet... It will come in couple of weeks
[17:11:31] <Tuipveus> pcw_home: ethercat-master is fine, I can buy beckhoff slave-terminal
[17:14:35] <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.
[17:15:00] <Tuipveus> Any help, links etc. greatly appreciated...
[17:15:30] <anonimasu> only one axis left :)
[17:15:48] <Tuipveus> I don't know much about c-programming, just some basics
[17:16:28] <Tuipveus> is there any commandlineinterface to "talk" directly with the beckhoff-slaves?
[17:16:33] <anonimasu> mrsun: small steppers, for servos you can get whatever rpm
[17:16:41] <anonimasu> mrsun: my big 1.9kw servos run up to 5k rpm
[17:17:48] <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.
[17:19:23] * anonimasu draws up a ball puller for the nc lathe
[17:21:26] <Tuipveus> so are guys (and girls) building everything from scratch like in Terminator movie, or are you using some industrial controllers with the cnc?
[17:23:22] <anonimasu> i do both
[17:23:42] <anonimasu> tho mainly i use industrial iron, coupled with homebrew bits and pieces
[17:24:00] <anonimasu> and also, i have some real machines of my own for actually making stuff on :p(atm)
[17:25:27] <Tuipveus> I just found this: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Etherlab and I was wondering if I can do the same
[17:25:52] <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
[17:27:10] <Tuipveus> :)
[17:27:47] <Tuipveus> about 30 minutes left, that is not bad
[17:28:52] <anonimasu> that means pulling a new piece of stock out every 20 seconds
[17:29:05] <anonimasu> opening and closing the spindle and doors to the machine
[17:30:01] <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
[17:30:24] <anonimasu> and pulling bars out i could have a 30 minute coffee break and swap tools in the mill
[17:30:29] <anonimasu> :p
[17:32:21] <Tuipveus> I have played mostly with Kuka-robots which have vxworks realtime operating system over the windows...
[17:36:32] <anonimasu> also i predict repeat stuff so i better get shit running on auto
[17:42:19] <anonimasu> nice stuff
[17:42:37] <anonimasu> i play with iec-61131 everyday at work pretty much when im not busy manufacuring things
[17:43:41] <anonimasu> well, linkage plate is done :]
[17:44:19] <anonimasu> baseplate left and force limiter
[17:44:19] <Tuipveus> anonimasu: which plc?
[17:44:36] <Tuipveus> I have done some programming also with beckhoff plc's and a littlebit with Siemens
[18:46:33] <Tom_itx> pcw_home, i'm getting 1.6 -1.6v on the differential inputs
[18:49:14] <Tom_itx> not sure why it's so low
[18:52:54] <r00t4rd3d> http://www.ebay.com/itm/CNC-ROUTER-MOUNT-HOLDER-FOR-DREMEL-4000-/190696089443?pt=LH_DefaultDomain_0&hash=item2c665f6763
[18:59:29] <r00t4rd3d> thats a new mount listing
[19:04:35] <skunkworks__> Tom_itx: that is what I was seeing on my differential encoders..
[19:04:51] <skunkworks__> might have been less.
[19:05:09] <skunkworks__> works though
[19:05:18] <Tom_itx> i'm not getting any leds on the mesa card like i was though
[19:05:41] <Tom_itx> i could wire up the differential side and try that
[19:05:55] <Tom_itx> it's got a resistor divider on it right now
[19:10:59] <Tom_itx> ok, i'm not sure what i did but it started working
[19:11:07] <Tom_itx> nothing really..
[19:11:17] <Tom_itx> i'll check for loose wires
[19:14:22] <Tom_itx> that may be the culprit, i just wiggled the board connector and it cut out
[19:25:21] <pcw_home> Yeah if you have > 200 mv change in the inputs the differential receiver should switch
[19:25:23] <pcw_home> TTL is about 3Vish anyway and 1.6V diff is 3.2V
[19:26:16] <Tom_itx> yep, i got about 3.3 3.4v from gnd
[19:26:24] <Tom_itx> thereabouts
[19:26:48] <pcw_home> I'm getting one of those sniglet crimpers for wiring those terminal blocks
[19:27:09] <Tom_itx> link?
[19:27:26] <Tom_itx> i'm not that crazy about them on the geckos
[19:27:45] <Tom_itx> you get some decent wire on them and they will become intermitten
[19:28:00] <pcw_home> http://www.ferrulesdirect.com
[19:28:07] <Tom_itx> i had the same thing on the z axis power connectors
[19:29:13] <pcw_home> what was intermittent?
[19:29:33] <Tom_itx> the z axis driver was cutting out
[19:29:57] <pcw_home> which power connectors?
[19:30:02] <Tom_itx> i added some slack in the wire harness and the problem went away
[19:30:19] <Tom_itx> the removable screw connectors they ship with on the 203v
[19:30:58] <Tom_itx> i've got 14ga wire on them
[19:32:05] <pcw_home> are those 5 mm spacing?
[19:32:18] <Tom_itx> i'm not sure
[19:32:25] <Tom_itx> they may be
[19:32:29] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/control5.jpg
[19:32:34] <Tom_itx> that's what it looks like
[19:32:43] <Tom_itx> the spagettin by the mesa card is gone now
[19:32:52] <Tom_itx> that was the last of the wiring, the pendant
[19:33:03] <Tom_itx> spagetti*
[19:33:27] <pcw_home> or 3.5 like ours (I dont think I'd use bigger than 20 gauge on the 3.5 mm)
[19:33:52] <Tom_itx> if they're good for 7A 20ga wouldn't be enough
[19:34:29] <Tom_itx> i used 18 on the stepper wires
[19:34:58] <pcw_home> we dont use any at 7A
[19:35:16] <Tom_itx> i'm not either
[19:35:23] <Tom_itx> 3.5 currently
[19:35:57] <pcw_home> I really dont like to use any tin connector at more than about 1/2 it rating
[19:36:04] <pcw_home> its
[19:36:14] <Tom_itx> i don't know what series they use
[19:36:35] <Tom_itx> connectors are always a pita on pc boards
[19:37:06] <pcw_home> due to heat --> higher resistance --> more heat loop
[19:37:58] <Tom_itx> i'll rework the one on the 7i47
[19:38:04] <Tom_itx> i'm being lazy right now
[19:39:17] <pcw_home> Since we are starting to make some cables with the terminal blocks the ferrules seemed like a good idea
[19:39:55] <Tom_itx> like theirs?
[19:40:12] <pcw_home> Whose?
[19:40:36] <Tom_itx> gecko
[19:41:11] <pcw_home> They have premade cables?
[19:41:25] <Tom_itx> not that i know of
[19:41:57] <r00t4rd3d> http://www.ebay.com/itm/12-volt-air-conditioner-portable-28qt-Aircraft-boat-RV-/160778667176?pt=Air_Conditioner&hash=item256f27c4a8
[19:42:15] <pcw_home> For example we make cable for 7I52/7I77/7I76 to sserial so its terminal block to RJ45
[19:42:33] <Tom_itx> ok
[19:43:29] <pcw_home> but its a little mickey mouse with just bare stranded wire in the screw terminals \
[19:43:31] <pcw_home> and likely to have stray strands
[19:44:13] <pcw_home> and tinning guarantees the wire breaks
[19:44:28] <Tom_itx> unless they're assembled carefully
[19:44:39] <skunkworks__> I have seen tiny copper crimps on the end of wires that go into terminal stirps
[19:44:41] <Tom_itx> with all strands inside the clamp
[19:44:53] <pcw_home> anyway we are going to try the sniglets
[19:45:04] * skunkworks__ tins usually......
[19:45:27] <pcw_home> yes thats what i am calling sniglets
[19:45:42] <pcw_home> proper term is wire ferrules
[19:46:05] <skunkworks__> ah
[19:46:15] * skunkworks__ just looked at pcw_home 's link
[19:46:36] * skunkworks__ likes talking about himself in 3rd person
[19:50:34] <pcw_home> I never remember the name of that place but "ferrules are us" works in google
[20:02:38] <r00t4rd3d> i have a push button estop, it does not lock down and twist to release, just makes contact then releases I believe. Do I wire that normally open or normally closed? I think N.O
[20:02:55] <skunkworks__> nc
[20:03:15] <skunkworks__> you want a failure in the estop circuit to stop the machine
[20:03:21] <skunkworks__> imho
[20:03:48] <Connor> Some one tell me if the endmills are any good ?
[20:03:49] <Connor> http://www.shars.com/products/view/4862
[20:03:57] <Connor> http://www.shars.com/products/view/4864
[20:04:03] <Connor> http://www.shars.com/products/view/4866
[20:04:15] <Connor> http://www.shars.com/products/view/4868
[20:04:22] <Connor> http://www.shars.com/products/view/4870
[20:05:00] <Connor> Using them mostly for Aluminum work. I've got them already.. but.. i need to get some new ones as I've broke the 1/8 and 1/4
[20:05:18] <Tom_itx> what rpm?
[20:05:23] <Tom_itx> http://www.lakeshorecarbide.com/
[20:06:58] <Connor> 2000 to 3000 is what I normally run.
[20:08:15] <Tom_itx> the carbide won't dull as quick
[20:08:23] <Tom_itx> run higher rpms
[20:09:24] <Connor> 3k RPM is tops.
[20:09:26] <Connor> for now.
[20:10:25] <pcw_home> Short to ground on estop wiring should estop as well as open
[20:10:27] <pcw_home> so control power --> NC estop switch --> stuff enabled by control power
[20:42:34] <FinboySlick> Tom_itx: You ever tried their high-feed mills?
[20:43:13] <FinboySlick> They seem pretty expensive but for fast shallow passes they seem pretty awesome.
[21:05:31] <Tom_itx> i haven't ordered from them but i'd like to
[21:05:37] <Tom_itx> i generally get mine locally
[21:05:46] <Tom_itx> jt likes them
[21:32:50] <Tom_L> test run: http://www.youtube.com/watch?v=XhU7S8kifJ4&feature=youtu.be
[21:38:04] <azureviolin> hi guys, I'm running linuxcnc in sim mode with axis_mm config
[21:38:42] <azureviolin> And when I execute some Gcode produced by pcb2gcode, I got error
[21:38:55] <azureviolin> like "cannot home while shared home switch is closed"
[21:39:28] <azureviolin> I googled the sentence, found nothing
[21:39:43] <azureviolin> any ideas how I can solve this problem?
[21:40:08] <azureviolin> I compiled linuxcnc on 64bit Ubuntu 12.04 Precise
[21:40:17] <Tom_itx> just a sec
[21:41:48] <azureviolin> Another problem would be, there's nothing shown on spindle area, and the sim stops when gcode tells it to spin. I need to jump over the spin code to continue running sim
[21:42:16] <Tom_itx> NO_FORCE_HOMING =1 in [TRAJ]
[21:42:23] <Tom_itx> try that
[21:42:48] <azureviolin> Hi Tom, Where do I input your instruction
[21:42:49] <azureviolin> ?
[21:43:51] <Tom_itx> in your machine ini file
[21:44:17] <azureviolin> oh. I'm using sim-axis_mm config
[21:44:29] <azureviolin> I'll try to find it and modify
[21:44:48] <azureviolin> However, I assume I don't need to change that to make it work, am I right?
[21:44:58] <azureviolin> since these are pre-set configs for simulation
[21:46:06] <Tom_itx> i've not used sim
[21:46:44] <azureviolin> okay, thank you though.
[21:47:42] <azureviolin> Actually, I'm developing a way to precisely cut PCB with CNC machine, based on probing method developed by phk.
[21:48:06] <azureviolin> Have you heard that anybody have done this before? other than phk
[21:49:03] <Tom_itx> no but there are others cutting pcbs
[21:50:03] <azureviolin> yeah, I'm aware of that. However, not everybody can cut a PCB with 1 mil track as phk have done. right
[21:50:06] <azureviolin> ?
[21:50:19] <r00t4rd3d> get a 1mm bit
[21:50:42] <azureviolin> 1 mil, which is 0.00254 mm
[21:50:59] <r00t4rd3d> oh
[21:51:01] <azureviolin> with 60 degree V bit
[21:51:25] <r00t4rd3d> hmm
[21:51:56] <azureviolin> check this out http://phk.freebsd.dk/CncPcb/
[21:52:00] <r00t4rd3d> do you have any pcb gcode? I want to try now :) I have a 60 V
[21:52:21] <azureviolin> he added a probe pin to parallel port.
[21:52:45] <azureviolin> And he designed his code for eagle's plugin: pcb-gcode
[21:53:14] <r00t4rd3d> yeah im reading that now
[21:53:23] <azureviolin> I want to make it more general, with pcb2gcode, which can take in general gerber file, outputs gcode
[21:53:32] <azureviolin> I'm working on this right now.
[21:53:40] <azureviolin> Enjoy your reading. It's amazing.

[22:00:32] <r00t4rd3d> ebay?
[22:03:08] <azureviolin> how does things go, r00t?
[22:07:29] <r00t4rd3d> ok, im not into pcb milling but maybe something I would like to try in the future
[22:07:45] <r00t4rd3d> just to see if I can
[22:35:24] <azureviolin> sure, r00t
