[04:58:43] <smellymoo> hey :)... got a robot arm, trying to identify the protocol of the serial data coming from the rotary encoder, google didn't help... properties. 0.5us per square wave, so 2Mbd?, 1 control that only has 1 shaped packet to start, no clock, 1 data line that shows evidence of a gap after each byte.
[05:27:38] <smellymoo> control line: <0 idle> 1101001000 data line: 11010001001011101101 <8 bits data that changes> 01 <8 bits that change> 01 <8 bits change> <0 idle>
[06:35:16] <pcw_home> sounds like a standard UART (8 bits 1 start bit (1) 1 stop bit(0))
[06:38:30] <Jymmm> pcw_home: up early, or up late?
[06:38:40] <pcw_home> Early
[06:38:45] <Jymmm> =)
[06:39:15] <Jymmm> pcw_home:
http://cell.weather.gov/radarhl.php?radar=kmux
[06:41:12] <pcw_home> Just gentle steady rain here (I thought it would be a bigger storm)
[06:41:41] <Jymmm> Yeah, last night's was WTH for a little bit.
[06:42:17] <Jymmm> pcw_home: how's your livestock doin?
[06:42:55] <pcw_home> Fine (well wet)
[06:43:18] <Jymmm> Oh, no barn or leanto shelter?
[06:43:45] <pcw_home> They have a shelter but still get wet eventually
[06:44:06] <Jymmm> Harbor Freight has 7x9 blue tarps for $3 with coupon
[06:45:55] <pcw_home> Their shelter is still OK but they wander down the hill to graze when the rain stops but often get caught if it starts raining again
[06:46:14] <Jymmm> pcw_home: Are you familiar with canopy tents? Oh, gotcha.
[06:47:32] <Jymmm> Not those flimsy "EZ-UP" ones, but the kind that use Metal conduit poles.
[06:48:11] <pcw_home> We may make a simple pole shelter this year
[06:53:24] <skunkworks__> pcw_home, been running the 7i80 'logging' setup a lot. No issues other than 1 random lockup. (I have my foot on the power supply at the time...)
[06:53:31] <Jymmm> pcw_home:
http://www.canopiesandtarps.com/canopy-fittings-flat-roof-fittings.html
[06:54:40] <Jymmm> pcw_home: This might be better suited for you
http://www.canopiesandtarps.com/canopy-fittings-low-peak-fittings.html
[06:54:57] <Jymmm> pcw_home: You can get the pieces at the flea market too.
[06:55:20] <pcw_home> Thats sort of like the vendors use at the flea market
[06:55:33] <Jymmm> pcw_home: Exactly.
[06:56:38] <pcw_home> Interesting we were considering wood/corrugated metal
[06:57:42] <Jymmm> pcw_home: Well, if you are looking for something more perm, you can do that. But this is just something alternative, but I'd use the solver and not blue tarps for longer life.
[06:57:53] <Jymmm> silver*
[06:58:07] <pcw_home> skunkworks__ : I have random lockups with Preemt-RT on some machines
[06:58:38] <skunkworks__> like I say - only once. This is a 2 core pentium 4
[06:58:58] <pcw_home> We have brown/silver tarps now (but those seem to vary widely in quality)
[06:59:13] <Jymmm> from HD ?
[06:59:37] <pcw_home> I think we got ours from OSH
[06:59:55] <Jymmm> Brown, Green, Blue are all crap.
[07:00:29] <pcw_home> first ones lasted 3+ years current ones I think only 1+
[07:01:08] <Jymmm> Well, maybe lumber structure might be better.
[07:01:09] <pcw_home> (same thickness but first had better UV protection or something)
[07:01:32] <pcw_home> Yeah
[07:01:35] <Jymmm> O think if you get tarps from the same place as the fittings, you would be ok.
[07:01:45] <Jymmm> I would think
[07:02:10] <Jymmm> OR
[07:02:43] <Jymmm> Use the canopy as a frame, and skin with something more durable
[07:03:06] <pcw_home> Thats a good idea
[07:04:40] <pcw_home> skunkworks__ : the one that locks up is a Core Duo 8400 (and what gets broken is X: you can still log in on the terminal screens)
[07:06:03] <pcw_home> Its not linuxcnc/Ethernet either, it will lock up without linuxcnc running (but never does with non RT kernel)
[07:06:12] <Jymmm> http://www.canopiesandtarps.com/super-heavy-duty-tarps.html
[07:07:08] <Jymmm> pcw_home: If it's a tent, you may not need a building permit too
[07:08:15] <pcw_home> Right
[07:09:35] <Tom_itx> i thought it never rains in SO Cal
[07:10:08] <Jymmm> pcw_home: I used one of these to create a 20ft antenna mast
http://www.canopiesandtarps.com/fffcbcc.html
[07:11:05] <Jymmm> Tom_itx: It doesn't, it's just everyone pissing on you at once ;)
[07:12:18] <pcw_home> skunkworks__ the D525 never has an issue (up a couple of months now)
[07:13:31] <pcw_home> thanks Jymmm, if we do replace the tarps it looks like that's the place to get them
[07:14:23] <Jymmm> pcw_home: Or try your local flea market, or I kow of a retail outlet in San Jose too...
http://www.playafy.com/south-bay-canopy
[07:15:25] <pcw_home> smellymoo: looks like a standard UART (Mitsubishi encoder?)
[07:18:03] <pcw_home> I recommend CRC RevEng if you want to figure out the CRC
[07:26:22] <pcw_home> To decode I would capture the data with a UART, then print the
[07:26:23] <pcw_home> bytes in binary as you turn the encoder to figure out the fields
[07:26:25] <pcw_home> (CRC is likely the last byte or some bits in the last byte)
[07:27:16] <jthornton> Tom_itx, latest
http://www.gnipsel.com/files/g-code-generator/mill-1.7.02.zip
[07:32:43] <pcw_home> jthornton: 45VAC into capacitor input filter is ~60V and 45vac x 9A is ~400W so
[07:32:44] <pcw_home> that would be the max continuous motor power (divided by the number of motors)
[07:33:24] <pcw_home> might be 48V motors
[07:35:03] <pcw_home> finally got sleepy bbl
[07:57:33] <sigiiCNC> Hi all
[07:57:48] <sigiiCNC> is here someono who use MMOCCAPY ??
[07:57:55] <sigiiCNC> someone
[07:58:23] <sigiiCNC> i have question about hal pins config :/
[07:59:00] <sigiiCNC> i can write in english/ oraz po polsku ;]
[08:01:24] <skunkworks__> sigiiCNC, I don't know if anyone here is using mmoccapy.. You might get a better responce on the forum
[08:01:41] <skunkworks__> (but ask your real question just in case...)
[08:15:24] <PetefromTn> mornin'
[08:20:14] <skunkworks__> it's friday!
[08:20:33] <Jymmm> skunkworks__: Time change, it's now Monday!
[08:20:50] <skunkworks__> crap! is it leep weekend again?
[08:20:53] <skunkworks__> leap
[08:21:22] <Jymmm> Yep, and next time change is back 7 days!
[08:21:52] <humble_sea_bass> WOOOOOO DAYLIGHT SAVINGS
[08:24:17] <PetefromTn> you had me scared there I thought I missed the time change whew...
[08:26:58] <jdh> you still have a week.
[08:27:03] <jdh> I'm looking forward to it.
[08:27:52] <jdh> Uruguay(?) goes an hour backwards that day.
[08:27:58] <PetefromTn> I'm looking forward to the damn temp changes..
[08:29:42] <skunkworks__> our area is looking at the 5th coldest winter since records in the 1800's
[08:30:30] <PetefromTn> I have lived here in East Tennessee for over 15 years and this winter has been by far the coldest...
[08:33:45] <humble_sea_bass> I don't remeber a colder winter since 96
[09:49:31] <PetefromTn> so anyone got a clue why my tool 1 offset which is zero shows as no offset in the tool table?
[09:49:52] <PetefromTn> I mean there is no number not 0.0 just blank.
[10:04:00] <JT-Shop> 2 RPC's gone, 1 to go
[10:05:41] <ReadError> atlanta has been shut down twice so far this winter
[10:05:46] <ReadError> which is rare
[11:56:14] <CaptHindsight> somebody needs to write a LinuxWeatherController or at least an android app
[12:00:20] <archivist> hmm weekend ddos script kiddies at it again?
[12:02:02] <Tom_itx> probably
[12:02:12] <Tom_itx> rucas
[12:02:14] <CaptHindsight> nah just M$ trying to get us all to use Skype
[12:02:32] <Tom_itx> google him and you'll see what he is

[12:05:43] <IchGuckLive> hi all ;-) and helau to all germans
[12:06:03] <CaptHindsight> Vas ist Los?
[12:06:31] <CaptHindsight> Der Hund ist los, und de katze ist in der keller...... old joke I know
[12:11:49] <CaptHindsight> IchGuckLive: the problems we were having with eh 5i25/6i25 wasn't the configs it was that you have to upgrade from the LiveCD from 2.4 (or was it 2.3) to 2.5 for all the configs to work
[12:13:46] <IchGuckLive> its better to start over on the CNC pc as loestmichel said yesterday and the wiki shoudt be clear about that
[12:15:13] <CaptHindsight> IchGuckLive: which wiki page? I was going to write very clear one
[12:16:12] <CaptHindsight> maybe I can just edit one that's already there
[12:16:24] <IchGuckLive> i woudt do it on the main update and on the mesa
[12:18:07] <IchGuckLive> CaptHindsight:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Mesa_Cards
[12:18:27] <CaptHindsight> leaving Chicago they called a "Bag Check" for my carry on that contained a PC, positioners, pneumatic controller, server valves and several feet of tubing and cables that went through xray
[12:18:42] <CaptHindsight> server/several
[12:18:56] <IchGuckLive> snow and cold in the USA no flake on the ground so far here in germany
[12:19:12] <jdh> no snow here
[12:19:13] <CaptHindsight> on the way back they didn't
[12:19:40] <IchGuckLive> 36deg in RIO the carnaval will be naked as every year
[12:25:29] <CaptHindsight> IchGuckLive: yes, I need to write the Mesa Cards page for Dummies
http://imagebin.org/296354
[12:27:27] <IchGuckLive> most do the jumper failure on the 5i25
[12:28:10] <CaptHindsight> or missing field power
[12:28:25] <CaptHindsight> on the IO boards
[12:28:41] <archivist> CaptHindsight, book for web development
[13:08:32] <CaptHindsight> heh, the new Evil LinuxCNC edition, runs from a remote server on a subscription basis
[13:13:19] <CaptHindsight> aren't some large CNC machine makers already doing similar? I heard that some are going to the point of installing GPS units in the machines so that if they are moved they stop working.
[13:14:21] <kengu> true

[13:28:44] <Connor> PetefromTn: Hey, What's up?
[13:29:14] <PetefromTn> Connor: nothing man how are u?
[13:29:45] <Connor> Okay.. Eye's a little strained.. new prescription, and trying to go back to contacts
[13:30:18] <jdh> plain contacts?
[13:30:32] <Connor> extend ware day/nigh
[13:30:42] <jdh> you < 40?
[13:30:46] <Connor> Yes.
[13:30:47] <Connor> 38
[13:31:20] <jdh> heh... I wore contacts until I was 40
[13:31:22] <Connor> Wore them a few years ago. then switched to my backup glasses when I got poison ivy in my eye.
[13:31:37] <PetefromTn> Connor: Did ya get the shaft ordered?
[13:31:46] <Connor> PetefromTn: Yes.. and my bearings.
[13:31:48] <jdh> well, past that, but it sucked. You can always lift up glasses to read, but not contacts.
[13:31:51] <PetefromTn> sweet..
[13:32:39] <PetefromTn> I spent some time accurizing my toolholder setup yesterday and got the runout on the new holders down to almost nothing LOL...
[13:32:58] <Connor> Cool.
[13:33:19] <PetefromTn> still cannot figure out why the tool 1 offset is not there now..
[13:33:26] <Connor> You ever figure out any more info on the tool changer? Like what kind of motor it has? and if it has a switch to indicate every time a tool is in position ?
[13:34:15] <PetefromTn> nope I need to. We are redoing the kitchen so have been busy..
[13:34:53] <PetefromTn> Also designing some new parts to make. Got an order for a custom scope rail here today.
[13:34:53] <Connor> Understood.. might be easier to email that guy and ask him.
[13:35:03] <Connor> nice
[13:35:08] <PetefromTn> No I will get to it man LOL...
[13:35:23] <PetefromTn> I did get the RS232-RS485 adapter here..
[13:38:19] <PetefromTn> We need to finalize the design for the base so I can figure out what kind of material I need to buy.
[13:38:38] <Connor> okay.
[13:38:52] <Connor> in pvt msg
[13:39:00] <PetefromTn> okay.
[13:55:02] <CaptHindsight> anyone work in an ITAR registered shop?
[14:02:09] <Jymmm> CaptHindsight: ITAR?
[14:02:20] <Jymmm> CaptHindsight: Um which "ITAR" are you spekaing of?
[14:03:59] <CaptHindsight> Jymmm:
http://en.wikipedia.org/wiki/International_Traffic_in_Arms_Regulations for cnc machines and shops
[14:04:40] <Jymmm> You need an ATF permit
[14:04:56] <pcw_home> Applies to electronics as well
[14:05:08] <Jymmm> munitions manufcturing permit
[14:05:16] <pcw_home> (ITAR)
[14:05:33] <CaptHindsight> looks like ITAR for the machines used to make parts as well
[14:06:38] <pcw_home> some cabled PCIE devices fall under those restrictions
[14:06:56] <Jymmm> pcw_home: ?
[14:07:20] <pcw_home> (allow building supercomputers)
[14:08:04] <Jymmm> pcw_home: Eh, they can't stop you legally from doing so, besides many are going ASIC anyway
[14:08:26] <pcw_home> They absolutely can stop us
[14:08:34] <Jymmm> not legally
[14:08:43] <pcw_home> legally
[14:08:49] <Jymmm> how?
[14:09:04] <pcw_home> arrest is a possibility
[14:09:36] <Jymmm> Eh, phil zimmerman went thru all this for us years ago.
[14:09:49] <pcw_home> we cannot ship certain things to certain countries
[14:10:03] <Jymmm> I wouldn't anyway.
[14:11:16] <CaptHindsight> people have gone to jail or be given hefty fines for letting foreign grad students see the wrong work in the lab
[14:11:17] <Jymmm> pcw_home: have you had requests to ship to ITAR restricted countries?
[14:11:30] <pcw_home> Yes
[14:11:35] <Jymmm> pcw_home: lol
[14:12:36] <Jymmm> pcw_home: mostly FPGA based items?
[14:12:41] <pcw_home> Most or maybe all of our stuff now has no restrictions but we have to be (and should be) careful
[14:12:42] <JT-Shop> anyone have an idea how to calculate the F word for inverse time mode?
[14:13:45] <Jymmm> If Fuck Off is future tense, then wouldn't inverse time mode be past tense then it be FUCK ON ?
[14:14:58] <Jymmm> pcw_home: What did you have that was restricted? Or was it a limit was removed?
[14:15:22] <Jymmm> s/limit/restriction/
[14:15:47] <Einar_> I got a file where "G28 W0 U0" is in the beginning. What are W and U? This is for a lathe.
[14:16:48] <humble_sea_bass> secondary coordinate system
[14:16:57] <humble_sea_bass> kind of like I and J
[14:17:56] <andypugh> Einar_: G28 is "go to predfined absolute position". (in the LinuxCNC dialect at least). W and U are the secondary X and Z axes.
[14:18:20] <andypugh> Was the code for a twin-toolpost lathe?
[14:18:28] <humble_sea_bass> The "U" letter address relates to X-axis incremental moves and the "W" letter address relates to Z-axis incremental moves.
[14:18:53] <andypugh> humble_sea_bass: Well, maybe. It would tend to be vaguely machine-dependent.
[14:18:58] <Einar_> It seems this is before a toolchange. Do I have to set these with a G28.1 first?
[14:19:14] <Einar_> It's a single toolchanger (rotary).
[14:19:19] <andypugh> If you don't have a U and W axis then it won't do anything.
[14:20:02] <humble_sea_bass> andypugh: good call.I was not aware that the U/W I/J convention was up for debated, but i should not be surprised
[14:20:36] <andypugh> I and J typically refer to an offset, but UVW are actual machine axes.
[14:21:18] <andypugh> (W is sometimes used as a tool-length offset along the spindle axis in a 5-axis machine, just to confuse matters)
[14:21:30] <Einar_> OK. I need it to go X+ close to home so the tools sticking out don't hit the bed. Is there an easy way to go to an abs. pos relative to the machine, not the workpiece?
[14:22:01] <andypugh> Einar_: You can put TOIOLCHANGE_AT_G35 or TOOLCHANGE_AT_G28 in the INI
[14:22:10] <andypugh> (from (imperfect) memoy)
[14:22:38] <Jymmm> andypugh: I thought we upgraded you to 640KB?
[14:23:04] <andypugh> No, I still have a wobbly 16k RAM pack.
[14:23:20] <Jymmm> andypugh: Get one of these SIMM Stackers...
http://www.retro-pc.net/musei/ram/simm72/p5.jpg
[14:23:30] <Jymmm> 72pin too
[14:23:41] <andypugh> http://farm4.staticflickr.com/3074/2671527140_fd269593b5.jpg
[14:24:02] <Einar_> I have an excellent memory! But I wish it was not so short.
[14:24:25] <Einar_> Tried to Google "TOOLCHANGE_AT_G28 linuxcnc". Got nothing.
[14:24:47] <humble_sea_bass> Einar_: get one of these cats
http://www.ebay.com/itm/SHARS-MAGNETIC-Z-AXIS-DIAL-SETTER-0004-GAGE-offset-pre-setter-tool-CNC-NEW-/300748405853?pt=LH_DefaultDomain_0&hash=item4606007c5d
[14:25:24] <humble_sea_bass> wait that's the answer to a question that wasnt asked
[14:26:05] <Einar_> I'll remember to ask that question later.
[14:26:27] <humble_sea_bass> http://www.linuxcnc.org/docs/devel/html/config/ini_config.html
[14:26:52] <humble_sea_bass> TOOL_CHANGE_AT_G30 = 1 - The machine is moved to reference point defined by parameters 5181-5186 for G30 if the value is 1. For more information on G30 and Parameters see the G Code Manual.
[14:30:40] <Einar_> Looks like what I want. The params will be remembered when starting Linuxcnc again later, or will I need to do that G30.1 again?
[14:31:19] <andypugh> They are sticky, stored in the vars file.
[14:31:39] <Einar_> Thanks!
[14:32:04] <andypugh> (might be worth checking the vars file to be absolutely sure)
[15:14:16] <PetefromTn> Damn that champfer cutter leaves a pretty finish hehehe
[15:17:47] <PetefromTn> Well apparetnly the lack of a number in my tool zero offset does not affect anything. It is just still zero. All the tools for this program worked correctly with their TLO's..
[15:25:56] <andypugh> PetefromTn: I saw you sounding happy on cnczone, and I was wondering if you sorted out your tool length?
[15:26:14] <PetefromTn> hey man I am ALWAYS happy ..
[15:26:23] <PetefromTn> But I did sort out the TLO..
[15:27:16] <andypugh> I have got in a tangle once or twice, but it does actually work.
[15:27:18] <PetefromTn> I was just wondering why with the new master we downloaded my tool 1 which has a zero offset and is my touch off tool all the other tools are referenced to does not have anything in the tool table under tool length..
[15:28:30] <andypugh> I guess nothing == 0 (but I would prefer not to assume that)
[15:28:37] <PetefromTn> I have not yet tried to use the cutter comp tho.
[15:28:44] <PetefromTn> yeah me too that is what I was worried about...
[15:29:21] <PetefromTn> I actually tried to manually edit it to 0.0 and save it and reopen the program and it was back to nothing...
[16:16:29] <Deejay> gn8
[16:38:28] <MrSunshine_> liquid ring vacuum pumps ... sounds like they are very sensetive to contaminated air? =)
[17:17:46] <Loetmichel> *HA* got my home CNC running again. It was just a loose coupling at the y-axis. but i had to dismante half of the machine to get to the y stepper. What did i think when constructing that motor into the back bottom of the machine?!?
[17:18:40] <Loetmichel> s/CNC/CNC mill
[17:20:05] <PetefromTn> Loetmichel What kinda machine is it?
[17:20:21] <Loetmichel> PetefromTn: a very small one
[17:20:36] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12569
[17:21:18] <PetefromTn> Hey that looks pretty sweet man..
[17:23:59] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=3037 <- the stepper for y is right in the "corner" of the column
[17:25:12] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12539 <- there it is ;-)
[17:26:22] <PetefromTn> Kinda tucked in there huh...
[17:26:28] <Loetmichel> yeah
[17:30:22] * PetefromTn[A] is now away - Reason : Goin' ta make some swarfmonkies...
[17:32:08] * PetefromTn is no longer away - Gone for 1 mins 46 secs
[17:32:49] <Loetmichel> that was short ;-)
[17:34:11] <PetefromTn> LOL just trying out a new chat client and clicked on the wrong thing hehe
[17:35:12] <Loetmichel> ... so now tghat the machine is running i can draw a 2 part heatsink for the antminers u1s and then modify them to 1.1V supply and 350MHz a.k.a 3.6 GH/s ;-)
[17:36:56] <andypugh> Rivett lathe blog is now finsihed up to date:
http://bodgesoc.blogspot.co.uk/2014_01_01_archive.html
[17:41:03] <FinboySlick> Wow, that's a beautiful little lathe.
[17:42:17] <PetefromTn_> Damn I missed it what lathe?
[17:42:38] <andypugh> It's a Rivett 608
[17:42:59] <andypugh> PetefromTn:

[17:43:41] <PetefromTn_> Oh okay I saw that picture already nice little lathe..
[17:44:04] <andypugh> It's not all that little actually. 40" bed length
[17:44:32] <PetefromTn_> Oh wow really it does not look that big in the picture...
[17:44:44] <andypugh> But an almost unique design.
[17:44:49] <FinboySlick> I like the feet. Monolyth pyramids from another time.
[17:45:34] <andypugh> Lots of info on the lathes.co.uk page:

[17:46:08] <PetefromTn_> I gotta thank you guys for all the help with my machine lately. I was out there making a part with it awhile ago and it just kinda dawned on me how nice it works and how much work it took to get here..
[17:46:35] <andypugh> I may need to learn how to do hand-flaking.
[17:47:21] <PetefromTn_> If it was not for you guys ideas and suggestions I would not have been able to do it.
[17:47:24] <FinboySlick> andypugh: Google just told me you had a skin condition ;)
[17:47:46] <PetefromTn_> Now I need a nice CNC lathe to do it again :p
[17:47:52] <FinboySlick> so I guess I should ask what's 'hand flaking'.
[17:48:39] <FinboySlick> Like chipping flint tools like cavemen?
[17:49:24] <andypugh> FinboySlick: Sure it wasn't the other Andy Pugh? (

[17:50:51] <FinboySlick> andypugh: We've seen her already... You can't hide behind that homonym anymore, we know your tricks!
[17:51:50] <FinboySlick> Anyway. I searched 'hand flaking' on google to palliate to my language barrier and only found skin conditions.
[17:52:38] <Tom_itx> andypugh, question is.. are you ever gonna use that lathe?
[17:52:57] <andypugh> Tom_itx: I can't decide :-)
[17:54:51] <Einar_> Andypugh: Put it in the kitchen and you can use it to turn carrots to EU standards.
[17:55:06] <andypugh> FinboySlick: It's the decorative finish that they applied to machine tools back then.

[17:55:12] <Tom_itx> or peel apples
[17:55:27] <andypugh> I think i would need to CNC it to peel apples
[17:55:54] <Tom_itx> or oranges... some of them can be a bugger to peel
[17:55:57] <andypugh> I will decide if it is a good lathe when I have rectified the wear in the front dovetail.
[17:56:17] <andypugh> If it is, then it might get an interesting CNC conversion.
