[00:28:28] <PCW> 3 mb/s Ethernet maybe only at Xerox in 1978
[00:30:09] <_methods> hehe
[00:30:32] <_methods> he slapped me with the token and stole ring
[00:30:35] <PetefromTn_> ;)

[00:34:00] <Tom_itx> PCW, what would it take to talk you outta a couple chips for my boards?
[00:34:26] <PCW> let me get a bag...
[00:34:42] <Tom_itx> hopefully the rest is still good
[00:34:54] <Tom_itx> i checked the 5v and it's good
[00:35:07] <Jymm> PetefromTn_: So, what you are saying is _methods is your bithc and you are her pimp?
[00:35:08] <Tom_itx> dunno what happened really...
[00:35:42] * Tom_itx thinks Jymm should act like an op in a respectable channel
[00:35:47] <_methods> hey i have feelings
[00:36:03] <PetefromTn_> hehehe
[00:36:08] <Jymm> _methods: Your are pretty
[00:36:09] <PetefromTn_> jealous?
[00:36:13] <_methods> hahah
[00:36:36] <Jymm> Tom_itx: Find me a respectable channel, this IS irc afterall
[00:36:52] <_methods> #reprap lol
[00:37:05] <_methods> #ubuntu
[00:37:07] <Jymm> _methods: I said respectable, not pathtic
[00:37:08] <pfred1> #recrap
[00:38:19] -!- patrickarlt has quit [Remote host closed the connection]
[00:38:44] <pfred1> think these brackets will be heavy enough for my CNC machine's corners? http://i.imgur.com/CDEloWf.jpg
[00:39:12] <pfred1> I could always weld gussets to them if they're not
[00:39:16] -!- rob_h has quit [Ping timeout: 255 seconds]
[00:39:30] <Tom_itx> how big is your cnc gonna be?
[00:39:48] <pfred1> the whole machine?
[00:39:58] <pfred1> I think it is about 3x4?
[00:40:10] <Tom_itx> plasma?
[00:40:13] <pfred1> like 3 feet wide and 4 feet long
[00:40:24] <Tom_itx> what are you making?
[00:40:29] <pfred1> wood router
[00:40:34] <Tom_itx> probably
[00:40:53] <pfred1> I had 1/8" anglesi n the corners and the thing bent up like a doamond on me
[00:40:58] <pfred1> diamond
[00:41:17] <pfred1> I wasn't too happy about seeing that
[00:41:28] <Tom_itx> use square tubing instead
[00:41:37] <Tom_itx> or weld a triangle
[00:41:46] <pfred1> so now I put angles on the outside threaded rod on the inside and these brackets in the corners
[00:42:01] <zeeshan> has anyone run emt conduit before?
[00:42:06] <pfred1> well, I am only done with one end
[00:42:11] <pfred1> I have
[00:42:28] <pfred1> but I'm no wizard bending it
[00:42:43] <pfred1> I know people who are so I know I'm not
[00:42:58] -!- andypugh [andypugh!~andy2@cpc14-basl11-2-0-cust1010.20-1.cable.virginm.net] has joined #linuxcnc
[00:42:58] <zeeshan> do you run a ground
[00:43:00] <zeeshan> even with emt?
[00:43:11] <zeeshan> er
[00:43:13] <Jymm> This clips are not half bad, 6/$1 at dollarstore http://www.dhresource.com/albu_276218779_00-1.0x0/multi-purpose-colorful-clip-clothes-folder.jpg
[00:43:13] <zeeshan> thats not what i meant
[00:43:20] <zeeshan> i mean do consider 4 conductors
[00:43:22] <zeeshan> when picking the size
[00:43:29] <pfred1> one good idea is to leave some blow line in
[00:43:38] <pfred1> in case you ever want to run more wire
[00:43:40] <Jymm> Thean can hold a sheet of paper and be screwed down
[00:44:03] <Jymm> without marring the matieral
[00:44:36] <Jymm> stronger than a clothespin
[00:45:01] <_methods> emt is cheap i always get enough to double the conductors i'm gonna pull
[00:45:05] <_methods> makes it easier to pull too
[00:45:32] <_methods> double the conduit size for conductors i mean
[00:46:22] <pfred1> zeeshan a ground is not required but considered good practice so it is up to you
[00:46:25] <Jymm> good for clamping laminate, veneer, pcb, etc
[00:47:31] <pfred1> yeah with EMT there is a limit to how many wires you're supposed ot stuff into it
[00:47:53] <pfred1> I mean you can't just pack them with as many wires as you can fit
[00:47:58] <PCW> Tom_itx OK 3 422 driver chips 74HC132-tssop and a couple FAN2001s (probably nearly impossible to solder) in a envelope
[00:48:00] <PCW> PM me your address and will mail tomorrow
[00:48:40] <Tom_itx> ok thanks
[00:49:40] <Tom_itx> U2 3 & 6 on the 7i47 and U9 on the 7i43
[00:50:40] <andypugh> So, I am making a clock with an Arduino. It is driving a 1 pulse every 30 seconds pulse-clock.
[00:50:57] <zeeshan> http://cdn.mrsupply.com/images/P/Siemens-HNF361_m.jpg
[00:51:01] <zeeshan> is there a non fused version of this?
[00:51:12] <zeeshan> 100A disconnect
[00:51:26] <Jymm> zeeshan: Why non fused?
[00:51:34] <Jymm> or do you want breaker?
[00:51:37] <zeeshan> i already have upstream breaker.
[00:51:43] <Valen> Tom_itx: did you break something?
[00:51:46] <Jymm> zeeshan: how far away?
[00:51:50] <zeeshan> 32 feet
[00:51:57] <andypugh> So that it has some idea of the last position it left the hands at after re-start or re-set I think I need to write the time of the last pulse to eeprom.
[00:52:00] <Tom_itx> Valen, yep
[00:52:04] <Jymm> zeeshan: get a breaker at least, it never hurts
[00:52:07] <Tom_itx> no idea what happened really
[00:52:09] <Valen> did you do something silly?
[00:52:15] <zeeshan> Jymm: there already is a breaker
[00:52:21] <zeeshan> upstream to the future disconnect switch
[00:52:24] <zeeshan> thats why it doesnt need to be fused
[00:52:24] <Jymm> zeeshan: more never hurts
[00:52:30] <andypugh> Now, the eeprom only has 100,000 writes and that gets used up pretty quickly with 30-second writes.
[00:52:31] <Valen> heh I defeated the current limit on mine with phat stacks of copper wire soldered onto the fet legs
[00:52:48] <Jymm> andypugh: why is it WRITING at all?
[00:52:54] <_methods> yeah why use the eeprom vs the tcr0a?
[00:53:17] <andypugh> Because I want to be able to recover from power failure
[00:53:21] <_methods> ahhh
[00:53:30] <Jymm> andypugh: thats what gps are for =)
[00:53:37] <Jymm> andypugh: and WWV =)
[00:53:40] <PCW> need some FRAM
[00:53:58] <andypugh> The whole basis of the clock is an MSF radio receiver.
[00:54:15] <andypugh> But it needs to know where the hands were last parked..
[00:54:24] <pfred1> I have one of those atomic radio clocks its is great
[00:54:26] <andypugh> The hand-control is open loop.
[00:54:26] <PCW> is there 12 noon index?
[00:54:35] <andypugh> No, no index.
[00:54:40] <PCW> rats
[00:54:56] <Tom_itx> Valen, i don't think so but you never know
[00:55:01] <Jymm> zeeshan: http://www.alcoelectrical.com/Creative%20Concepts%20036.jpg
[00:55:12] <andypugh> It occurred to me that the cheapest way to get feedback of the hands is probably a web-cam at the other side of the Quadrangle :-)
[00:55:13] <Tom_itx> i'm gonna have to go thru the whole wiring and make sure it's all good
[00:55:14] <zeeshan> sexy!
[00:55:21] <zeeshan> why is that disconnect switch so huge
[00:55:26] <PCW> sense a power failure and write EEPROM only then
[00:55:39] <_methods> have limit switches on the hands
[00:55:44] <_methods> like those rotor switches
[00:55:56] <Jymm> andypugh: battery back?
[00:56:10] <_methods> or optical encoders
[00:56:21] <Valen> why are they in 2 boxes is what I want to know ;->
[00:56:33] * Valen loans andypugh a supercap
[00:56:35] <Jymm> andypugh: http://www.hobbytronics.co.uk/real-time-clock-module-ds1302
[00:56:52] <andypugh> So, my thinking is that I have 100,000 writes but I have 1k of eeprom, so I can write the 3 x MSBs to addresses 0, 1 and 2, then use byte 4 to indicate where byte 4 is stored….
[00:57:11] <Tom_itx> PCW the FAN2001 those 3 legged SOP chips?
[00:57:19] -!- sumpfralle has quit [Read error: No route to host]
[00:57:25] <andypugh> (Sorry, store byte 4 at the address pointed to by byte 3).
[00:57:33] <PCW> 6 pin QFNs I think
[00:57:36] <andypugh> Anyone see a flaw with this plan?
[00:57:52] <Tom_itx> oh i see em

[00:58:54] -!- AR__ [AR__!~AR@] has joined #linuxcnc
[00:59:05] <Tom_itx> andypugh why not use flash?
[00:59:08] -!- sumpfralle [sumpfralle!~lars@vmd6311.contabo.host] has joined #linuxcnc
[00:59:15] <andypugh> Clock is easy. It is remembering where the hands were last in the event that someone presses reset, plugs in a serial terminal, pulls the plug etc
[00:59:20] <Tom_itx> i suppose they have about the same write cycle
[01:00:14] <andypugh> With 1k of eeprom I can easily have 50 years at 100,000 writes. I think I will be beyond caring by then. :-)
[01:00:39] <Tom_itx> or you'll be working on rev 2
[01:00:47] <PCW> is it really EEPROM or flash EEPROM
[01:01:03] <Jymm> andypugh: Why not the battery backed RTc I linked to? You COULD use a SUPERCAP with it as well
[01:01:05] <Tom_itx> use one of those serial eeprom
[01:01:16] <PCW> (can you erase a single byte/word?)
[01:01:26] <Tom_itx> i doubt it
[01:01:31] <andypugh> It isn’t the actual time that is the problem.
[01:01:33] <Tom_itx> they're probably block or chip erase
[01:01:48] <Tom_itx> SD is 512byte blocks
[01:02:08] <andypugh> This is only a 1k eeprom, but that is a good question.
[01:02:37] <PCW> for flash you can just write the count plua a serial number and find the largest serial numberwith valid checksum, at startup
[01:02:54] <andypugh> Jymmm I am not storing the time, I am storing the last position the hands were left in
[01:03:18] <_methods> zero out the hands after a power off
[01:03:18] <Tom_itx> yeah just increment the eeprom address and read the last one written
[01:03:30] <_methods> then have them move to the correct time
[01:03:51] <andypugh> _methods: And how do I know where the hands are to zero them?
[01:04:14] <_methods> add a sensor or switch to the hands
[01:04:30] <_methods> hall sensor
[01:04:57] <Jymm> andypugh: In school, all the mechical clocks were slaves to a MASTER mechclock in the schools office, sync to the recess bells. I remember after a power failure, they would spin like crazy to the correct time. Maybe look into what they did?
[01:05:51] <andypugh> _methods: It’s this clock: http://farm1.static.flickr.com/3/4657514_53908e6bb7.jpg
[01:05:51] -!- sumpfralle has quit [Read error: Connection reset by peer]
[01:06:23] <andypugh> Jymm: Yes, this was exactly that type of clock, but the Master was in a building that has been demolished....
[01:06:24] <_methods> heheh well that's one way to tell me to STFU lol
[01:06:26] <Jymm> andypugh: is the black area metal?
[01:06:45] <andypugh> Jymm: Yes
[01:07:30] <Jymm> http://www.instructables.com/id/Arduino-based-master-clock-for-schools/
[01:07:34] <pfred1> andypugh just get a bunch of Raspberry Pis and run ntpd on them all :)
[01:07:58] <andypugh> I thought about Pi and NTP, but I want something that will run for decades.
[01:08:10] <pfred1> LInux will do that
[01:08:19] <Jymm> andypugh: http://www.hvtesla.com/masters/masters_index.html
[01:08:33] <pfred1> donno how long a Raspberry Pi will last though
[01:08:42] <andypugh> Yeah, I have seen all these pages :-)
[01:09:07] <pfred1> recap it with solid state caps and it'll probably last
[01:09:09] <Jymm> andypugh: http://www.hvtesla.com/masters/slaves_intro.html
[01:10:55] <_methods> http://playground.arduino.cc/Code/I2CEEPROM
[01:11:04] <_methods> add a secondary eeprom
[01:11:13] <pfred1> http://www.10000yearclock.net/learnmore.html
[01:13:29] <andypugh> _methods: That might help. I guess it rather depends on if that is block-erase and if the Arduino eeprom is block-erase…
[01:13:51] <_methods> well i wonder if you could spread it betwee multiple eeproms
[01:14:20] <_methods> have multiple sacrificial eeproms to spread the writes between
[01:14:21] <andypugh> Was the suggestion of searching for the highest serial that the eeprom chips know which cells are empty?
[01:14:23] <_methods> cheap too
[01:15:03] <_methods> not sure how i'd tag the latest write location
[01:15:16] <_methods> yeah keep them all empty
[01:15:21] <_methods> just shift it
[01:15:38] <Jymm> andypugh: Just realize that no matter how much you fuck up the clock, it' be right twice a day =)
[01:15:58] <pfred1> Jymm that is not true with digital displays
[01:16:13] <Jymm> pfred1: It aint digital though (yet)
[01:16:42] <pfred1> the digital display atthe gas station I go to is unintelligible
[01:16:57] <pfred1> it is always like 72:99
[01:17:14] <andypugh> So, perhaps I read the MSBs, then just look for the highest value in any other location. I think this will need a deeper understanding of exactly how the eeprom is managed.
[01:17:20] <Jymm> andypugh: Do you have no way of attahing anything to the clock arm axels ?
[01:17:47] <andypugh> Not without modifying the antique mechanism :-)
[01:18:01] <Jymm> andypugh: any pics in the internal mechs?
[01:18:20] <andypugh> Yes, I am uploading as we speak.
[01:18:25] <Jymm> k
[01:19:54] <pfred1> andypugh replace the guts with steppers and use LinuxCNC!
[01:20:21] <Jymm> andypugh: I'm thinking there AHD to be some way to know it's position previously.
[01:20:25] <Jymm> HAD*
[01:21:58] <andypugh> No, they jut trusted them to work, and a little man had a full-time job looking after every clock on campus.
[01:22:19] <Jymm> andypugh: (seriously?)
[01:22:25] <andypugh> Yes
[01:22:42] <Jymm> lol, ok. I'll wiat for the photos =)

[01:23:57] <andypugh> But another fun idea I have is to make the clock always show Sidereal time. It is a science college, after all. :-)

[01:27:21] <PCW> bbl Dinner!
[01:27:26] <Tom_itx> does the 3.3 feed the 1.2 or both from 5v?

[01:33:13] <andypugh> Yes. But It is rather small and buried.
[01:33:47] <andypugh> I will see how it goes. These things always used to run open-loop. It should be fine.

[01:36:37] <Jymm> lol
[01:36:55] <Jymm> andypugh: Oh, does this clock have a bell/chime?
[01:37:02] <andypugh> Quite a few coils work on 24V DC or 240V AC.
[01:37:22] <andypugh> No, no chime. But we could add one now.

[05:04:21] <XXCoder> yo
[05:04:21] <pfred1> hello
[05:04:25] -!- patrickarlt has quit [Quit: Leaving...]
[05:04:36] <ssi> first heat treating experience went quite well
[05:04:50] <pfred1> any caveman can do it huh?
[05:05:00] <ssi> I suppose
[05:05:13] <ssi> I've never tried to do it the caveman way, but doing it the sophisticated way came out quite nice
[05:05:22] <ssi> parts didn't seem to move much at all
[05:05:26] <ssi> maybe a couple tenths, maybe
[05:05:27] <pfred1> I had a job noce where i heat treated printing press dies

[05:05:46] <pfred1> we warped a few of those real bad
[05:05:55] <ssi> lol
[05:06:12] <pfred1> the super didn't think it was so funny
[05:06:21] <ssi> I made some tapered bushings that I would like to have for riflesmithing
[05:06:23] <pfred1> I mean potato chip
[05:06:24] <ssi> and I'm about to heat treat them
[05:06:28] <ssi> but I cut them wrong :(
[05:06:32] <ssi> so I have to remake them anyway
[05:06:38] -!- tjtr33 [tjtr33!~tjtr33@c-24-14-156-156.hsd1.il.comcast.net] has joined #linuxcnc
[05:06:38] <ssi> but I'm interestd to see what the ID does
[05:06:43] <pfred1> we used an arsenic oven?
[05:06:45] <ssi> cause they're reamed to .375
[05:06:55] <pfred1> in the morning it looked like this rusty bucket of white powder
[05:06:59] <ssi> and it needs to be a hydraulic fit on a piece of thompson shaft
[05:07:12] <pfred1> the nwe'd fire it up and it would turn into this molten glowing red goo after a while
[05:07:17] <ssi> lol
[05:07:21] <ssi> sounds dangerous
[05:07:23] <pfred1> it was pretty funny
[05:07:29] <pfred1> oh unreal dangerous
[05:07:30] <ssi> I have a little fiber oven
[05:07:36] <ssi> does pretty well
[05:07:49] <pfred1> we'd wire up the dies with tie wire and dip them into that glowing goo
[05:07:58] <pfred1> we had like a rod over the furnace we'd tie them to
[05:08:14] <pfred1> then we'd fish them out and quench them in barrels of salt water
[05:08:27] <pfred1> whoosh! the water would go shooting up the wall!
[05:08:31] <ssi> I be.t
[05:08:35] <pfred1> these dies were liek an inch thick
[05:08:37] <ssi> I'm hardening O1
[05:08:39] <XXCoder> http://hackaday.com/2014/12/04/cutting-glass-with-cnc/
[05:08:44] <ssi> and I bought some honest to god quench oil
[05:08:49] <ssi> and the quenching is pretty uneventful, thankfully
[05:08:56] <ssi> there's a little flame the instant it's dunked, but goes right out
[05:08:57] <pfred1> and when we fished them out they were like translucent almost as if you could see right through them
[05:08:58] <ssi> minimum smoke and smell
[05:09:08] <pfred1> it was weird
[05:09:31] <tjtr33> skunkworks, maybe your opencv can track andypugh's clock hands by doing angle recognition https://www.youtube.com/watch?v=njab2bBps6U
[05:09:35] <pfred1> I mean I've heated up some steel but nothing like what we were doing at this joint
[05:10:22] <pfred1> well before I got there they used to oil quench but they had some problems i heard
[05:10:24] <unfy> i've been meaning to fiddle with opencv, just haven't yet ._.
[05:10:42] <pfred1> I didn't lasti n that place too long it was kind of messed up
[05:11:01] <pfred1> we also hard chrome plated stuff there
[05:11:11] <ssi> that stuff is horrible for you
[05:11:15] <pfred1> yeah
[05:11:33] <pfred1> we had a plastic apron that was so filthy dirty no one wanted to wear it
[05:11:39] <pfred1> that was our safety gear
[05:12:02] <pfred1> there were some masks hanging on hooks on the wall I can't tell you how long they'd been hanging there
[05:12:13] <pfred1> no one wore thoseeither
[05:12:26] <pfred1> you kinda held your breath when you went into the vat room
[05:13:40] -!- tjtr33 has quit [Quit: Leaving]
[05:13:56] <pfred1> place cuold have used better management let me tell you
[05:14:39] <pfred1> the guy that was there before i was went out to lunch one day and never came back
[05:14:59] <pfred1> a week later i quit myself
[05:21:46] <ssi> heh I don't balme you
[05:22:08] <ssi> I need to get my surface grinder wired so I can grind these test blocks
[05:22:32] <pfred1> I've run a surface grinder
[05:22:46] <pfred1> man when I got taught how to do that I thought it was the silliest thing I'd ever done
[05:23:01] <pfred1> the way you have to spin the two handles
[05:23:14] <pfred1> I was good at it though
[05:23:27] <pfred1> man i could make a finish like a magnetic tape
[05:23:40] <ssi> I wouldn't say I'm good at it
[05:23:41] <pfred1> you know how some tapes sort of look like a rainbow?
[05:23:49] <ssi> I still haven't gotten to where I can make a really nice finish
[05:23:56] <pfred1> yeah you'll get it
[05:23:58] <ssi> and I don't have the intuition for setups on the grinder like I do on the mill
[05:24:00] <pfred1> dress the wheel a lot
[05:24:07] <ssi> I need to figure out where my diamond is
[05:24:20] <pfred1> yeah you'll never get a good finish if the wheel ain't dressed
[05:24:35] <pfred1> place i worked for that's what they made wheel dressers
[05:24:42] <pfred1> so we always had 'em
[05:25:07] <pfred1> we did a big business in industrial diamonds too
[05:25:15] <pfred1> that was what kept the shop going when I worked there
[05:25:45] <pfred1> other than that the place was a joke
[05:25:57] <pfred1> but we had soem nice machines to play with
[05:26:30] <pfred1> in its hey day that shop had 40 people on the floor when I was there there were 6 of us

[15:53:39] <Rab> He seemed to think it was OK, generated a successful CAM job with it. It supposedly uses "the cloud" somehow, I don't know if that means designs are stored remotely or what.

[16:04:35] <renesis> yeah using it might suck
[16:04:36] <ssi> and having the whole thing freeze because the internet burbles is obnoxious
[16:04:43] <taiden> except that Fusion has 3 axis machining
[16:04:49] <taiden> HSMexpress is 2.5d only
[16:04:54] <renesis> ya
[16:05:14] <taiden> just tried it out on my cnc router
[16:05:24] <taiden> the built in EMC post seems to work extremely well
[16:05:34] <taiden> I will be purchasing a subscription
[16:05:44] <renesis> oh shit it has emc post?
[16:05:47] <taiden> yes
[16:05:55] <taiden> it's also $40 a month or $300 a year
[16:06:09] <renesis> i would still prob have to remove toolchange and spindle shit, shrug
[16:06:17] <taiden> no idea
[16:07:06] <renesis> its free if student or startup
[16:07:06] <taiden> yes it is
[16:07:06] <renesis> and as student it didnt request verification
[16:07:06] <taiden> it's also free for DIY use but you have to request it
[16:07:06] <renesis> so its basically free
[16:07:06] <mozmck> Has anyone tried weber systems synergy?
[16:07:06] <taiden> it seems they only require you to pay if you're making product
[16:07:06] <mozmck> http://www.webersys.com/

[16:07:06] <ssi> getting there
[16:07:06] <renesis> cloud thing is the only really annoying part
[16:07:10] <mozmck> If I remember the price was somewhere around $800 for the full 3D CAD/CAM
[16:07:15] <renesis> ui is annoying but thats pretty standard for CAM
[16:07:22] <taiden> well
[16:07:25] <taiden> I came from Mastercam
[16:07:31] <taiden> and if you want to talk about annoying UI...........
[16:07:34] <taiden> ..................................
[16:07:34] <renesis> right
[16:08:10] <taiden> it also has 4th and 5th axis indexing
[16:08:22] <renesis> but yeah the way it splits tasks between left and right click menus is dumb
[16:08:38] <taiden> i find myself having to shoot for the enter key a lot which is annoying
[16:08:59] <taiden> i feel like i should have a foot pedal bound to RETURN
[16:09:06] <renesis> ha
[16:09:36] <renesis> i like the stock setup
[16:09:56] <renesis> boundaries in 2d would be nice
[16:11:34] <taiden> i usually throw down some geometry and island pocket
[16:11:41] <taiden> it works ok
[16:12:16] <taiden> (assuming im thinking of what youre speaking about)
[16:14:55] <renesis> im importing from solidworks
[16:15:26] <renesis> ive done simple geometry in fusion to do slots and bores on origin
[16:16:20] <taiden> is solidworks available in monthly subscription yet?
[16:16:35] <renesis> i dont like the CAD part of it, but compared to SW everything is annoying
[16:16:43] <renesis> i dunno i have student edition

[16:51:32] <ssi> hey pete
[16:51:41] <PetefromTn_> hey
[16:51:50] <PetefromTn_> got a question for you machinist gurus
[16:52:02] <PetefromTn_> just got a small job for a large local customer
[16:52:15] -!- tekniq [tekniq!~tekniq@50-80-21-243.client.mchsi.com] has joined #linuxcnc
[16:52:26] <PetefromTn_> and it is a pair of mirror image prototypes.
[16:52:43] <PetefromTn_> just simple plate aluminum
[16:52:44] -!- tekniq has quit [Remote host closed the connection]
[16:52:55] <PetefromTn_> but it has a .050" radius all around the perimeter.
[16:53:18] <PetefromTn_> I usually use a 1/16" radius for easing edges like this
[16:53:42] <PetefromTn_> but I am trying to determine if I should just order an .050 corner rounding endmill
[16:54:14] <PetefromTn_> or just cut the .0625" endmill shallow a touch which will make it easier to avoid lines should the offset not be exactly perfect?
[16:54:28] <ssi> I would let the customer know that the non-standard radius callout will require a tool purchase and increase the cost
[16:54:38] <ssi> and give them the option to change the callout if it's non-critical
[16:54:43] <PetefromTn_> job has already been quoted
[16:54:56] <PetefromTn_> figured in additional tooling
[16:54:59] <jdh> what's the tolerance on teh 0.050" ?
[16:55:05] <ssi> then unless there's a tolerance quoted on the radius, you're buying a cutter :)
[16:55:14] <PetefromTn_> just wondering if I can get away with the .0625 or not
[16:55:39] <ssi> a .0625 rounding tool at a shallow depth doesn't create a .050 radius
[16:55:48] <PetefromTn_> yeah I realize that
[16:55:57] <jdh> but it probably isn't measurable
[16:56:01] <PetefromTn_> but the difference would be almost impossible to tell
[16:56:15] <ssi> so if the print says .050+/-.0000 and you quoted it, that's what you're supposed to produce :)
[16:56:15] <jdh> you would know
[16:56:19] <PetefromTn_> and this is more of a visual kind of part than it is a precision part
[16:56:36] <ssi> well thats sort of my point; give the customer the opportunity to tell you it's non-critical
[16:56:47] <PetefromTn_> I considered that.
[16:56:58] <ssi> cause every once in awhile that'll bite you in the ass, it'll be an engineering decision on their end
[16:57:20] <PetefromTn_> I was going to go ahead and order a new corner rounded double end carbide anyways for the job
[16:57:29] <ssi> what's the tool cot
[16:57:30] <ssi> cost
[16:57:30] <PetefromTn_> it would give me another option for tighter stuff on my custom rails
[16:57:35] <PetefromTn_> about $40.00
[16:57:40] <PetefromTn_> plus ship
[16:57:41] <ssi> just go ahead and get it
[16:57:43] -!- bobo_ [bobo_!63283ad9@gateway/web/freenode/ip.] has joined #linuxcnc
[16:57:55] <ssi> you already quoted it with the tool price included, and you get to keep the tool
[16:58:21] <PetefromTn_> yeah but If I can cut it with the .0625 I have here I can save a few precious pennies LOL
[16:58:43] <PetefromTn_> the quote included tooling only in my view they are not aware of it.
[16:58:50] <PetefromTn_> just gave them a price to make the parts
[16:58:58] <PetefromTn_> and the finish
[16:59:00] <PetefromTn_> and delivery
[16:59:09] <PetefromTn_> so nothing earth shattering here
[16:59:15] <PetefromTn_> and it is a one off pair of prototypes
[16:59:27] <PetefromTn_> but I DO want to make them very very happy here
[16:59:33] <PetefromTn_> so I get further work
[16:59:40] <PetefromTn_> this is the second job I have done for them
[16:59:49] <PetefromTn_> hoping to get more and more as time goes on.
[17:00:16] <jdh> buy the tool and use it, ask them for tolerance relief, be scum and deliver known out of spec parts.
[17:00:50] <ssi> yes, two of those options are fine options
[17:01:03] <jdh> I thought they were phrased suitably
[17:01:04] <ssi> personally for $40 I'd be inclined to try to make it exactly to the print and have another tool in my chest
[17:01:05] <PetefromTn_> thats harsh
[17:01:20] <PetefromTn_> thanks
[17:01:30] <ssi> if we were talking about a $200 tool I'd be on the phose confirming the tolerance
[17:02:02] <jdh> I'm guessing you were planning on doing the right thing anyway, you just wanted the interwebbes to confirm your integrity.
[17:02:15] <PetefromTn_> well I know for most shops that would not even be a consideration
[17:02:21] <PetefromTn_> but for me every dollar makes a difference
[17:02:42] <ssi> yeah I know, which is why calling them and confirming tolerance is a perfectly valid option
[17:02:45] <PetefromTn_> for instance with this job I need to order the materials and cutters out of pocket
[17:02:58] <PetefromTn_> and once the job is completed I won't be paid for a week or more
[17:03:11] <PetefromTn_> so yeah even a $40.00 bit plus shipping is a consideration.
[17:03:15] <jdh> I hate asking people to do that for us since we pay net 180
[17:03:24] <ssi> they're humans, just call them and tell them "hey you called this out as .050, I have a .0625 cutter on hand. Is there an engineering need for this to be .050 radius, or can I approximate it with the cutter I have?"
[17:03:38] <ssi> if they have a legit reason for the radius, which they likely DON'T, they'll tell you
[17:03:43] <PetefromTn_> The bit will certainly come in handy in the future as all my bits do
[17:03:48] <PetefromTn_> sure
[17:03:51] <PetefromTn_> I may just do that.
[17:03:55] <jdh> it's generally pretty random for edge breaking
[17:03:57] <ssi> that's the easiest way to go
[17:04:04] <PetefromTn_> Just received an email from the engineer wishing me a merry christmas
[17:04:18] <JT-Shop> yea, many times it is just a default number in the cad software
[17:04:19] <ssi> yeah they probably drew it in solidworks and added a fillet around the edge and just picked a number that looked aesthetic
[17:04:23] <PetefromTn_> agreed that is why I thought I might be able to get away with the non spec cutter size
[17:04:32] <PetefromTn_> thats what I do LOL
[17:04:38] <ssi> the disconnect between engineers and machinists is often a big issue :)
[17:04:41] <JT-Shop> I have to pay attention or all my radius end up being 0.100" in solidworks
[17:04:45] <PetefromTn_> worst case scenario I can just 3d mill the contour
[17:04:56] <ssi> yeah you don't want to do that, it'll take a million years and not look as good
[17:05:02] <PetefromTn_> not really
[17:05:05] <PetefromTn_> done it several times
[17:05:18] <PetefromTn_> especially on a part that will be bead blasted as this one will
[17:05:36] <PetefromTn_> and I could do it with a ball endmill I already have
[17:05:47] <PetefromTn_> but I could really use the new tool
[17:05:51] <PetefromTn_> on future stuff
[17:06:31] <PetefromTn_> money is just really tight right now around here.
[17:07:15] <jdh> thanks obama
[17:09:14] <ssi> lul
[17:09:49] <PetefromTn_> well like I said I recently bought that new lathe, moved it here, bought a brand new AC system and everything I needed to install it, and Christmas is coming REALLY REALLY FAST... I really need some work right now around here or it is gonna be a slim Christmas that is for sure.
[17:10:11] <ssi> I'm in somewhat the same boat
[17:10:16] <ssi> but thankfully I ignore christmas
[17:10:32] <PetefromTn_> well when you have two little Girls that is an impossibility

[17:12:07] <PetefromTn_> not bad
[17:12:10] <ssi> not terrible
[17:12:13] <ssi> it's small, but it works well
[17:12:14] <PetefromTn_> I need to get one at some point
[17:12:17] <ssi> and it's big enough for most tooling I'd make

[17:35:41] <ssi> yeah I'm gonna cover the ways when I grind
[17:35:53] <ssi> it's about the only way to finish grind the part I'm working on unfortunately

[17:38:56] <ssi> hm you know
[17:39:04] <ssi> well no
[17:39:13] <ssi> there are two challenges
[17:39:25] <ssi> I can do OD grinding on the surface grinder in a spin index
[17:39:33] <ssi> but cutting that taper accurately is going to be hard
[17:39:53] <ssi> taper attachment on the lathe is still set to the angle I cut
[17:40:02] <ssi> so I can just use the taper attachment with a post grinder to finish grind it
[17:40:23] <ssi> second challenge is ID grinding; I could set up a spin index on the surface grinder, and set up a fixture to hold the air spindle to the grinder head
[17:40:26] <ssi> but that sounds like a bunch of work
[17:40:38] <ssi> but then the combo challenge is grinding those two diameters concentric
[17:40:46] <ssi> doing it on the lathe in one setup guarantees concentricity

[17:47:44] <ssi> yeah but if I do it in a spindex with a sine bar, I can't ID grind in the same setup
[17:48:00] <ssi> well yeah I guess I can

[18:26:31] <PetefromTn_> Got the LED edge lit sign material mounted up and touched off. getting ready to engrave that thing now.
[18:26:36] <PetefromTn_> Should be fun!

[18:50:47] <tjtr33> yes, same trick allows you to detect where a hand is above a plexi plate http://goo.gl/m9oDu
[18:51:27] <PetefromTn_> neat I will have to check that out after I get this machined. Gotta get my kids from school soon and want to get this done...Appreciate the idea

[20:19:37] <PetefromTn_> you and me both..
[20:19:44] <ssi> heheh

[20:21:03] <PetefromTn_> I got the LED's here but yeah I can try to use a flashlight to kinda get a looksee.... It really came out beautiful.
[20:21:19] <PetefromTn_> Only issue was that carpet tape is UNBELIEVABLY strong
[20:21:29] <ssi> yeah it is heh
[20:21:31] <PetefromTn_> I thought I was gonna snap it pulling it off the substrate
[20:21:52] <ssi> I have some doublesided tape that is sold in woodworking shop as turners' tape
[20:22:01] <ssi> I use it to tape 1/4" MDF router templates down
[20:22:17] <PetefromTn_> It actually pulled the protective backing off the plastic instead of coming off the substrate so I am gonna have to see if I can remove that shite..
[20:22:39] <PetefromTn_> The machine did a beautiful job and the cuts are SOO clean in the engraving.
[20:22:55] <ssi> heck yeah
[20:23:08] <PetefromTn_> Hang on lemme see if I can get a pic with the LED flashlight on it.

[20:41:01] <a1cypher> Any ideas how to resolve this? I found a pull request on the git page for someone who seems to have fixed it, but I cant quite figure out how to actually see his change to the configure.in file
[20:42:41] <cradek> what branch are you building?

[20:43:00] <a1cypher> master I believe
[20:43:16] <cradek> odd - that builds on lots of x86_64 platforms
[20:43:33] <a1cypher> It could just be some stupid default setting somewhere.

[20:53:22] <_methods> oh you want to array a toolpath
[20:53:33] <_methods> just use a sub
[20:54:03] <cradek> for a linux-rt kernel you should build uspace
[20:54:06] <_methods> or have 4 work offsets
[20:54:15] <_methods> and run the same program at each work offset
[20:54:24] <a1cypher> uspace ?
[20:54:39] <taiden> does ncgui have this feature?
[20:54:43] <taiden> it's been forever since I looked into it
[20:55:23] <cradek> I'm bothered that your kernel headers aren't in the right place
[20:55:27] <a1cypher> is that an option during ./configure
[20:55:32] <cradek> why not use the packaged debian linux-rt kernel?
[20:55:54] <a1cypher> Not sure, I just built my own from source.
[20:56:05] <cradek> why?
[20:56:15] <_methods> what is ncgui? is it like a little conversational style plugin or something
[20:56:22] <a1cypher> I wasnt sure where to find the prepackaged one I guess. I could change it, but I dont think the kernel is the problem
[20:56:30] <taiden> it might be legacy now, im not sure
[20:56:41] <_methods> ah it's like a conversational plugin
[20:56:45] <cradek> sorry, I have no reason to believe or not believe your kernel is right
[20:56:45] <taiden> it used to have little functions built in

[21:15:00] <cradek> on the other hand if you can contribute fixes to support trusty I'd be happy to review them
[21:15:07] <cradek> it uses xfce

[21:19:44] <PetefromTn_> not a bad idea
