[00:04:41] <ssi> making a spider for the left end of the spindle
[00:04:52] <ssi> only suitable stock I could find was 3" roundbar
[00:04:58] <ssi> took ages to turn it down to 1.75 "
[00:06:12] <zeeshan> lol
[00:06:17] <XXCoder> ouch
[00:06:24] <zeeshan> use your cnc!
[00:06:34] <ssi> none of the cnc machines are operational yet!
[00:06:45] <zeeshan> http://i.imgur.com/BYpT0Ht.png
[00:06:46] <zeeshan> comments?
[00:06:54] <zeeshan> i wonder if this will work the way i think it will
[00:07:01] <ssi> what am I looking at
[00:07:05] <zeeshan> a mount
[00:07:17] <ssi> for?
[00:07:18] <zeeshan> so its adjustable in the dovetail axial direction
[00:07:20] <zeeshan> in 3 spots
[00:07:26] <zeeshan> using an indent type of setup
[00:07:34] <zeeshan> then its adjustable in two rotational axis
[00:07:40] <zeeshan> its a calibration jig
[00:07:45] <zeeshan> for the cameras for my experiment at school
[00:08:08] <zeeshan> im hoping with enough force
[00:08:13] <zeeshan> i can make those detents jump
[00:08:38] <ssi> just select the springs carefully
[00:08:40] <zeeshan> the detents forcing towards the orange plate
[00:08:43] <zeeshan> theyre dual purpose
[00:08:49] <zeeshan> they take up 5 thou of slack in the dovetail
[00:08:54] <zeeshan> cause im too lazy to machine gibs
[00:09:05] <zeeshan> yea i was thinking of buying a random spring kit
[00:09:08] <zeeshan> and cutting them to length
[00:09:12] <zeeshan> and just doing it by feel
[00:09:20] <ssi> I hope the clearance between this spider and the spindle bore isn't so much as to cause a problem
[00:09:21] <zeeshan> the holes are threaded too
[00:09:23] <zeeshan> so i can compress the springs
[00:09:31] <ssi> I'd hate to have to remake it :P
[00:09:46] <zeeshan> whats the id?
[00:09:50] <ssi> 1.403"
[00:09:58] <zeeshan> whats the spindle bore id? :p
[00:09:58] <ssi> and this came out 1.395"
[00:10:02] <tjtr33> maybe just buy vlier pins what toolmakers use http://vlier.com/product_index/mechanical/mech_09_springpin.html
[00:10:06] <ssi> spindle bore id is 1.403
[00:10:17] <ssi> od of the small end of the spider is 1.395
[00:10:49] <zeeshan> tjtr33: but then i cant adjust the feel for em
[00:11:04] <tjtr33> you can buy difernt spring pressures
[00:11:24] <ssi> about to chuck this thing up in a 5C 3-jaw chuck in a spin index bolted to the mill to drill and tap it
[00:11:38] <ssi> I have a rotab but I don't have a chuck or anything for it
[00:11:41] <tjtr33> 2.3 to 67.5 lbs
[00:11:43] <ssi> need to get that done
[00:13:38] <tjtr33> gnite
[00:13:41] <zeeshan> gnite!
[00:17:01] <zeeshan> http://i.ebayimg.com/00/s/NTMxWDgwMA==/z/2YYAAOSwEppUUETw/$_20.JPG
[00:17:02] <zeeshan> what in the world
[00:17:03] <zeeshan> is this
[00:18:17] <zeeshan> Bergonzi model LP 1250 box drill
[00:18:47] <zeeshan> now thats a drill press!
[00:21:28] <XXCoder> long arm that's for soure
[00:28:06] <toastydeath> hahaha
[00:28:29] <toastydeath> that's a small radial arm drill
[00:29:21] <toastydeath> bigger one:
[00:29:22] <toastydeath> https://s3.amazonaws.com/machinetools_production/uploads/2013462/24758.JPG
[00:29:47] <toastydeath> 4' and under is small, 6' to 8' is midsized, anything over is big
[00:30:00] <toastydeath> for drilling large castings
[00:30:13] <XXCoder> toastydeath: the one rule about industual machines
[00:30:18] <XXCoder> theres always bigger
[00:30:24] <toastydeath> nah they top out at about 12'
[00:30:33] <XXCoder> for now
[00:30:35] <toastydeath> i think the biggest one ever made was like 14' or some shit
[00:30:38] <toastydeath> and nobody uses them anymore
[00:31:14] <XXCoder> I remember this sci fi books
[00:31:18] <XXCoder> somewhat crappy but..
[00:31:50] <XXCoder> they have this tech to make pure black shape that cause anything that touch to fall out of universe (atoms not whole thing at once)
[00:32:03] <XXCoder> they used some as "drill bits" and so on
[00:32:13] <XXCoder> I bet that'd be awesome as cnc tooling too
[00:32:33] <XXCoder> it dont even need to rotate. 0 rpm at whatever ipm machine can go max at
[00:33:23] <XXCoder> actually it can't curve so wou;d have a flat profile. probably need to rotate for nice even round cutting "surface"
[00:35:40] <XXCoder> gonna love sci fi. night.
[00:39:44] <toastydeath> lol
[00:39:50] <toastydeath> night!
[00:41:13] <zeeshan> wow toastydeath that is huge.
[00:43:07] <unfy> got an electronics question
[00:43:30] <unfy> just started testing stuff, and more than one motor appears to be expressing it
[00:44:22] <unfy> it seems once per full rotation the motor is getting a 'pulse' in it. as in when holding the motor and the axis test run is going, every rotation you can feel a thud
[00:47:40] <pcw_home> what type of motor? What type of drive?
[00:56:51] <[cube]> what do you guys think of this lot?
[00:56:51] <[cube]> http://www.kijiji.ca/v-electronics/ottawa/cnc-stepping-motors-stepper/1035933096
[00:57:03] <[cube]> anything useful in there?
[00:57:19] <[cube]> im planning to convert a manual mill in a couple months
[00:57:24] <[cube]> (first time)
[01:10:52] <unfy> pcw: found it, it was... kind of a math / division thing
[01:11:52] <unfy> and, just a generic lpt breakout board -> individual tb6560 drivers -> nema17 bipolar
[01:15:53] <unfy> but, a single axis quick test on some hardware i will NOT be using - works :D
[01:16:02] <unfy> rather, a PC i will not be using
[02:09:59] <Deejay> moin
[07:03:07] <jthornton> anyone using dgarr/moveoff on a machine yet?
[07:47:23] * jthornton wonders why anyone would rather type in goto([-,-,10]) than G0 Z10 all those brackets and junk just drive me nuts typing
[07:48:17] <Tom_itx> who does that!?
[07:49:55] <jthornton> that gm something or other on the mailing list
[07:50:12] <jthornton> he is a C programmer and thinks it is easier to write G code in C
[07:51:11] <Tom_itx> he must be a c hacker instead
[07:52:01] <Tom_itx> or afraid to learn another language
[07:52:08] <Tom_itx> which is a rather simple one
[08:06:44] <_methods> no doubt
[08:06:51] <_methods> not like gcode is that complicated
[08:07:24] <_methods> there was some other guy in here the other day having all kinds of problems with his program
[08:07:33] <_methods> everything was a variable
[08:09:59] <_methods> or some convoluted calculation
[08:13:11] <rob_h> u mean when u walk upto a CNC and find some kind sole wrote a hole program using varables , so to mod it takes all day to read over it
[08:13:37] <PetefromTn_> love that heh
[08:13:41] <_methods> yes
[08:13:54] <_methods> holy macro
[08:14:01] <_methods> is usually what i say
[08:14:25] <PetefromTn_> I wish I understood more about macros... I almost never use them
[08:14:37] <_methods> i use them for very specific things
[08:15:05] <PetefromTn_> I do basically everything in CAM and only even write hand coded stuff for very simple things
[08:15:10] <_methods> but i remember when i used to try and use them for everything lol
[08:15:21] <_methods> pissed of a lot of people
[08:15:37] <_methods> then a month later when i'm trying to work with the old program again i learned my lesson
[08:15:58] <_methods> comments.......even from yourself are usually useless lol
[08:16:47] <_methods> i've had setup guys get pissed at me for using subs too lol
[08:16:55] <PetefromTn_> I have learned to write copious comments to myself because invariably I forget whaddahell I did the last time I made that part even if it was just last week LOL
[08:18:29] <PetefromTn_> Just made another one of those Steyr Short picatinny rails. This time a bead blasted finish. Looks pretty sweet!!
[08:18:37] <_methods> ahh the real reason russia invaded ukraine
[08:18:39] <_methods> http://www.latimes.com/world/europe/la-fg-russia-turkey-putin-energy-20141201-story.html
[08:21:25] <PetefromTn_> http://i.imgur.com/1rHrqtk.jpg
[08:21:46] <PetefromTn_> http://i.imgur.com/JgdoEDw.jpg
[08:22:48] <_methods> ah nice
[08:23:22] <_methods> cycle time on that thing?
[08:24:10] <PetefromTn_> well about an hour or so. actual machine time from
[08:24:25] <_methods> from start to finish?
[08:24:45] <PetefromTn_> main body is about an hour
[08:24:54] <PetefromTn_> then the picatinny part takes another 20 or so
[08:25:06] <_methods> yeah that's alot of slots
[08:25:34] <PetefromTn_> yeah and I cut them with an 1/8 endmill because I am stupid and did not get a slightly larger one LOL
[08:25:49] <_methods> 2 passes for each slot?
[08:25:51] <PetefromTn_> you like it?
[08:25:58] <_methods> hell yeah man it looks great
[08:26:03] <PetefromTn_> well actually it runs down the middle
[08:26:13] <_methods> you need to start makin them for ar's
[08:26:17] <PetefromTn_> then it cuts tapered to the edge minus .01
[08:26:18] <_methods> probably sell way more
[08:26:30] <PetefromTn_> then it finish passes each slot
[08:26:41] <PetefromTn_> so once it is done with a slot it is done period
[08:26:58] <PetefromTn_> but the real time eater is the triangular profile down each side
[08:27:07] <PetefromTn_> and the slotting underneath it.
[08:27:20] <PetefromTn_> I do the entire picatinny profile from the vertical
[08:27:29] <PetefromTn_> so it is all the same every time for sure
[08:28:01] <PetefromTn_> Honestly I would make them for AR's but from what I have seen everyone and their brothers brother make them often shitty and ill fitting and cheap.
[08:28:31] <_methods> well if you make a quality one some of those guys will pay top dollar i'm sure
[08:28:40] <PetefromTn_> my next door neighber is an AR nutjob
[08:28:40] <_methods> money seems to be no object to gun nutz
[08:29:00] <_methods> we get walkins all the time
[08:29:03] <PetefromTn_> he brought over all of the picatinny accessories he had to test fit my new rail.
[08:29:05] <_methods> wanting crazy gun mods
[08:29:16] <PetefromTn_> shit send em my way I NEED the work LOL
[08:29:46] <_methods> we just had a guy come in with an rp-90 we had to do some work on
[08:29:49] <PetefromTn_> only about half of them fit right and that was usually the most expensive ones. A lot of it is plastic crap
[08:30:12] <PetefromTn_> or poorly cast pot metal stuff
[08:30:17] <_methods> yeah
[08:30:46] <PetefromTn_> the real picatinny rail profile information is online to see and read and very little of what is labeled picatinny actually fits right
[08:31:31] <PetefromTn_> I have been beating the ground around here visiting all the local companies and shops trying to get work and it is like pulling fucking teeth sometimes to get even a little job.
[08:32:04] <_methods> yeah it's rough doing job shop stuff
[08:32:25] <PetefromTn_> I feel like there is not much I cannot make and I think my parts show I can make a pretty part if I need to.
[08:32:28] <_methods> i never know if i'll have a job one month from the next
[08:32:46] <PetefromTn_> I doubt I will ever get used to that part of the game
[08:33:00] <_methods> it's stressful for sure
[08:33:27] <_methods> i can't wait till i'm retired and i can just make parts in my garage for spending money
[08:33:38] <PetefromTn_> I gotta get this rail mailed out this morning. Gonna visit the last company that sent me some work and see if they have anything.
[08:33:59] <_methods> you been hitting up the maint depts in big factories?
[08:34:12] <_methods> we get a lot of repair work from guys like that
[08:34:23] <PetefromTn_> I have visited quite a few of the local companies yeah
[08:34:24] <_methods> or small run production jobs
[08:34:43] <_methods> yeah it sux you really gotta hit them at the right time
[08:34:56] <_methods> if you walk in when they need something done you'll get it
[08:35:04] <_methods> but you gotta have the time to go hit them up
[08:35:22] <PetefromTn_> I spoke this morning to a fellow I used to do work for that owns a company that makes some cool bicycles and he needs some parts made he is sending over some drawings today. HOPEFULLY I will get that work at a reasonable price.
[08:35:33] <PetefromTn_> Oh I GOT THE TIME!! LOL
[08:35:57] <_methods> well if you got the time...doughnuts and coffee can go a long ways to drumming up some work
[08:36:10] <_methods> stop in and drop off doughnuts and coffee lol
[08:36:29] <PetefromTn_> not a bad idea really. sometimes I can't afford the donuts LOL
[08:36:30] <_methods> that's always a good tactic lol
[08:36:41] <_methods> yeah maybe just once a month
[08:36:53] <_methods> drop off some cards and donuts and coffee
[08:37:49] <PetefromTn_> I may just try that this morning. There is a DD on the way over there.
[08:38:07] <PetefromTn_> nothing works like a good sugary snack hehe
[08:38:11] <_methods> yep
[08:38:30] <_methods> do that a couple times and they'll remember you
[08:38:48] <PetefromTn_> if that doesn't work I will just get on my hands and knees and beg :O
[08:38:53] <_methods> hahaha
[08:39:32] <_methods> some places though other people are giving them better "donuts" and you'll never get in
[08:39:52] <_methods> unless you can give better "donuts"
[08:39:57] <PetefromTn_> those must be some freakin gold plated donuts..
[08:40:02] <_methods> deep sea fishing trips
[08:40:06] <_methods> hehe
[08:40:10] <_methods> yes gold plated donuts
[08:40:20] <_methods> disney world vacations
[08:40:24] <_methods> you know
[08:40:25] <PetefromTn_> ya gotta pay to play huh
[08:40:29] <_methods> yeah
[08:40:37] <PetefromTn_> shit I cannot even afford that for myself.
[08:40:48] <_methods> yea
[08:40:49] <_methods> yet
[08:41:37] <PetefromTn_> I am kinda proud of that Steyr rail design tho. Not bad for a NON-engineer type
[08:42:00] <_methods> engineers make functional stuff
[08:42:07] <_methods> designers make pretty stuff
[08:42:19] <PetefromTn_> then I must be of the designer bent I guess
[08:42:25] <_methods> looks that way lol
[08:42:35] <PetefromTn_> I get bored with just drill and tap and slot too much
[08:42:53] <PetefromTn_> most of the reason I got into CNC was to be able to make smooth contours and curves etc. etc.
[08:43:01] <PetefromTn_> eye candy stuff.
[08:43:31] <PetefromTn_> can't wait to get this CNC lathe working so I can play with making some neat stuff on that machine.
[08:43:46] <_methods> how much you have left on it?
[08:43:52] <PetefromTn_> even on my manual lathe I made a lot of curvy contours
[08:44:22] <PetefromTn_> well honeslty I just don't have the money to get it done so it will probably have to wait until I get my tax returns or something to buy the damn CNC parts.
[08:44:40] <PetefromTn_> I could probably get it working inside a month easily if I had the parts I need for it.
[08:45:01] <PetefromTn_> right now I am just refinishing the sheetmetal panels and cleaning it up
[08:45:37] <_methods> i wish i had the space to have some real machines
[08:45:44] <PetefromTn_> it is starting to look like a lathe again but I am missing the rear sheetmetal panel behind the bed
[08:45:45] <_methods> one day
[08:46:06] <PetefromTn_> I just have a 25x25 shop nothing special at all.
[08:46:34] <_methods> i need to try and talk some people into making a coop space
[08:46:43] <PetefromTn_> I also have to make the arm that will hold the pendant they stole that off of it.
[08:47:37] <PetefromTn_> I have some square tubing for it just gotta cut and tig weld it together.
[08:48:08] <PetefromTn_> and I have to make a rear support vertical member for the sliding headstock cover top rail support.
[08:48:30] <PetefromTn_> that will also probably just be square steel tube and some plate.
[08:49:21] <PetefromTn_> will probably have to get that rear panel bent up at a local sheetmetal shop as it will be pretty long and have multiple bends in it. it will also need to be thicker than I can reasonably bend here.
[09:02:18] <PetefromTn_> Well gotta head out to the Post office. BBL.
[09:31:53] <JT-Shop> assembly table prepped and ready
[09:32:13] <_methods> what're you assembling?
[09:32:44] <JT-Shop> air filter kits I make for the Spyder
[09:32:55] <_methods> ahh
[09:35:44] <_methods> every time i think of those spiders i just see kenny powers lol
[09:38:37] <_methods> http://28.media.tumblr.com/tumblr_lz19oxjg5E1qd0z3co1_500.jpg
[09:39:18] <_methods> oooh better pic

[10:08:50] <Guest31645> I'm trying to hook up my VFD. It's a WJ200. I see there are drivers for this on 2.6. Can anyone help me finding these and tell ing me what they do? Are they modbus drivers?
[10:23:36] <jthornton> should be in the man pages
[10:24:36] <jdh> there is a wj200_vfd comp
[10:25:25] <jthornton> I'm not seeing that in the 2.6 man pages
[10:27:14] <jthornton> Guest31645, not taking any chances are you?
[10:27:31] <jthornton> forum, mailing list, IRC...
[10:27:45] * jthornton looks in the files
[10:28:39] <jthornton> I see the wj200 component... wonder why there is no man page
[10:29:30] <cradek> it's polite to ask in one place at a time, because otherwise you waste a lot of others' time answering your questions in several disparate threads
[10:29:38] <jthornton> Guest31645, are you still here?
[10:29:40] <cradek> jthornton: seb answered about that on the mailing list
[10:29:41] <jthornton> exactly
[10:29:52] <jthornton> ok, thanks
[10:31:09] <_methods> http://www.lorenzpotthast.de/petroglyphomat/
[10:33:39] <ssi> morn
[10:36:13] <Rab> Strip away the academic language and I think they've got Rube Goldberg's cordless drill.
[10:36:26] <_methods> heheh
[10:37:08] <Rab> Nice Stonehenge photoshop, though--sure to provoke.
[10:39:56] <ssi> people build the dumbest crap
[10:40:13] <_methods> different strokes i guess
[10:40:35] <_methods> i'm sure some clown will put a 3d printer nozzle on it
[10:41:55] <jdh> like lixpen.com ?
[10:42:11] <_methods> is that that 3d printer pen
[10:42:17] <jdh> one of them.
[10:42:31] <jdh> the video is carefully edited to never show the end of a stroke
[10:43:00] <syyl_ws> i love that line, _methods :D
[10:44:08] <_methods> hehe
[10:44:43] <syyl_ws> i always get a itchy feeling when i hear 3d printing or reprap
[10:45:05] <archivist> it is pronounced rep crap
[10:45:20] <_methods> hahahah
[10:45:21] <syyl_ws> oh lord :D
[10:45:26] <syyl_ws> just felt of my chair
[10:45:46] <syyl_ws> i also like "3rd industrial revolution by 3d printing"
[10:46:13] <syyl_ws> until i cant print brakedisks and calipers for my car with a consumermachine, its no revolution.
[10:47:10] <CaptHindsight> it's all the hype for the toy CNC glue guns, those sellers have no shame
[10:47:35] <syyl_ws> :D
[10:47:39] <syyl_ws> oh
[10:47:50] <syyl_ws> a guy at work bought a ultimaker2
[10:47:58] <syyl_ws> he showed me a few parts he printed
[10:48:01] <syyl_ws> they look ok
[10:48:06] <syyl_ws> but its plastic
[10:48:07] <jdh> key fobs?
[10:48:11] <CaptHindsight> they know it's a scam, they are just providing those suckers with a device to spend their money on
[10:48:12] <jdh> logos?
[10:48:19] <syyl_ws> crap that catches dust in the shelf, yes
[10:48:35] <CaptHindsight> FDM has a place but not for what they hype it to be for
[10:48:35] <jdh> but, you could print a gun!
[10:49:04] <syyl_ws> i could knock a gun out with a lathe, a tigwelder and some black steel pipe.
[10:49:07] <archivist> a potato gun
[10:49:26] <CaptHindsight> here's an actual good application http://www.3ders.org/articles/20141201-adidas-develops-new-springblade-footwear-using-3d-printing-technology.html
[10:49:47] <CaptHindsight> they are able to print the molds in a few days vs weeks
[10:50:04] <syyl_ws> we also had parts from lasersintered molds
[10:50:06] <syyl_ws> hmm
[10:50:10] <syyl_ws> not to impresive ;)
[10:50:21] <syyl_ws> we could machine a simple cavitiy in the same time
[10:50:24] <CaptHindsight> 48hours vs 3-6 weeks for tooling
[10:51:06] <Rab> It's a good application, but it's definately not FDM.
[10:51:10] <CaptHindsight> you can also SLA print those soles in a few minutes
[10:51:19] <syyl_ws> ok thats true :D
[10:51:38] <CaptHindsight> no, that is laser with metal powder
[10:52:17] <CaptHindsight> DMLS direct metal laser sintering
[10:52:56] <CaptHindsight> then they injection mold with PA12
[10:53:23] <jdh> we have laser sintering. surface finish is awful
[10:53:34] <Rab> Custom prosthetics are one of the few FDM applications that actually made me sit up and take notice.
[10:53:36] <CaptHindsight> if the kids at reprap really wanted to innovate they would be working on other techniques
[10:54:01] <syyl_ws> that form# thing looks interesting
[10:54:03] <CaptHindsight> but they just want to peddle their glue guns
[10:54:08] <syyl_ws> with the resinbath
[10:54:32] <CaptHindsight> that is SLA, but the form1 is really slow since it uses a single laser
[10:54:35] <Rab> I think I might wear a glove over a filament prosthetic in public, though.
[10:55:03] <syyl_ws> just replace it with an hook
[10:55:08] <Rab> As opposed to some wicked sintered titanium thing.
[10:55:27] <syyl_ws> terminator ;)
[11:15:50] <CaptHindsight> http://www.3ders.org/articles/20141202-7-year-old-girl-receives-new-3d-printed-custom-made-bionic-arm.html
[11:16:32] <CaptHindsight> if they used SLA they could print that prosthetic in minutes vs days
[11:26:57] <crash112> Hi all
[11:27:48] <crash112> PCW: Are you really out out of stock of the 7i76e cards?
[11:28:06] <crash112> I was hoping to have a new NC machine up and running b4 christmas
[11:29:35] <pcw_home> I think we have 16 back from assy (assy error), will add to store today
[11:30:08] <crash112> Excellent!
[11:33:21] <crash112> How are they under linuxcnc now? It's just a hobby machine, so I don't mind if I have to put a bit more time in to get it running perfectly.
[11:35:23] <crash112> I'll order a 5I25 as well incase I run into problems
[11:39:59] <crash112> PCW: also, will you be releasing a 7i77e at any point in the near future?
[11:57:28] <pcw_home> crash112: the Ethernet cards need Linuxcnc 2.7 or master built for uspace and a preemt-rt kernel
[11:57:29] <pcw_home> so you either need to install the buildbot debs or compile the linuxcnc source (so a bit more work than just using the iso)
[12:01:34] <Loetmichel> *MHMMM* nice stuff. but needs a BIT more water... there is fire in there... (not exactly a whiskey glass, closest i could find in the kitchen ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=15413
[12:21:31] <Jasen> Hi pete
[12:42:42] <Guest31645> Yes I'm here.
[15:54:14] <jdh> are you sure?
[15:54:24] <jdh> anyone know what this is: http://myrtlebeach.craigslist.org/hvo/4785620950.html
[15:54:58] <PetefromTn_> Its a shoptask machine 3 in 1
[15:55:11] <PetefromTn_> I used to have one before they made the bridgemill
[15:56:46] <syyl_> uh
[15:56:50] <syyl_> the bridgemill looks funny
[15:57:38] <syyl_> a pretty beefed up version of the small 3in1 machines :o
[15:57:49] <PetefromTn_> it does but I am sure it goes a long way to strengthening the millhead on an otherwise halfway decent machine. I enjoyed mine
[15:58:11] <jdh> I'm not seeing the 'ability to put a cnc computer on it"
[15:58:17] <PetefromTn_> The lathe part of the machine was the better part
[15:58:32] <PetefromTn_> I could see one setup as an interesting gang tool setup.
[15:58:58] <PetefromTn_> they actually came setup for accepting motors on the table even when I bought mine.
[15:59:17] <PetefromTn_> It was the first machine I ever owned and I had it a LONG time ago.
[15:59:23] <jdh> where the handwheels are?
[15:59:37] <PetefromTn_> nothing like a good seperate lathe and mill but pretty decent for a 3 in 1
[16:00:03] <PetefromTn_> no actually the motors went on the back of the table and at the end of the Z travel. the millhead was a different story
[16:01:19] <PetefromTn_> that looks like an early bridgemill I think.
[16:01:50] <PetefromTn_> don't get me wrong it is still a 3 in 1 machine and has its compromises
[16:02:05] <Connor> http://shopmasterusa.com/
[16:02:09] <PetefromTn_> but for what it was it was not too bad really especially for a hobby machine.
[16:02:10] <Connor> Very funny looking machine.
[16:02:45] <PetefromTn_> whats funny looking about it?
[16:03:03] <Connor> Just kinda funny looking.. I dunno.. :)
[16:05:15] <PetefromTn_> its just another chinese machine after all.
[16:05:52] <PetefromTn_> but I must say that the base of the machine would make for a cool gang tool lathe since you are basically using the X axis of the mill table to run your cross slide on.
[16:31:16] <PetefromTn_> https://www.youtube.com/watch?v=IrlY8qEmO3I interesting setup
[16:37:42] <Deejay> gn8
[17:06:27] <unfy> pcw: thanks again for lsat night :D
[17:21:40] <unfy> Lookinag the getting started guide and a few other things, it looks like expected to roll own gcode or use something to convert dxf's.. or maybe openscam/blendercam ?
[17:22:24] <unfy> the documentation is awesome about gcode itself and setting up linuxcnc - but not really about how ya generate projects to feed into it ._.
[17:23:49] <unfy> and gcode reminds me of logo.
[17:23:57] <Tom_itx> that part is left up to you
[17:24:01] * unfy shudders to think back to that turtle of childhood
[17:24:14] <Tom_itx> gcode standard for most cnc machines
[17:24:49] <unfy> tom: so... it'd be the Cam page on the wiki ? as someone completely new to CNC stuff, this appears to be an initial stumbling block
[17:24:51] <Tom_itx> some hand write gcode others use fancy cad cam to do so
[17:25:22] <Tom_itx> cam generates gcode from the cad
[17:25:35] <unfy> so it'd be finding a cad program that supports it, or maybe a dxf to gcode converter etc. i understand.
[17:25:37] <Tom_itx> gcode is then interpreted by linuxcnc to movements on your machine
[17:25:49] <Tom_itx> 2d or 3d?
[17:26:03] <Tom_itx> there are a fair amount of 2d programs out there for free or little cost
[17:26:14] <unfy> understood
[17:27:38] <unfy> that would explain one of the other softwares that came on a cd with .... i think the breakout board
[17:27:47] <unfy> some windows software with 'cam' in its name.
[17:28:06] * unfy will find an OSS or linux software for it <3
[17:29:42] <unfy> tom: tnx btw <3
[17:31:04] <Connor> PetefromTn_: Do you know what he was making in that video? https://www.youtube.com/watch?v=IrlY8qEmO3I
[17:31:38] <PetefromTn_> it says a bugle mouthpiece why?
[17:31:54] <Connor> Looks like maybe a Trombone / baritone moutpiece.
[17:31:58] <Connor> Oh. I missed that.
[17:32:04] <PetefromTn_> yeah
[17:32:09] <PetefromTn_> pretty cool really
[17:32:21] <PetefromTn_> I have often considered doing something like that on the VMC.
[17:32:29] <PetefromTn_> The mill 2 lathe setup is interesting.
[17:32:38] <Connor> I have done a little of that.
[17:32:56] <Connor> but, not a gang tool setup like that.
[17:33:53] <PetefromTn_> I can do up to 7/8 inch I think with my ER32 setup but a small three jaw chuck is probably a bit better. never seen a Cat40 setup that way that I recall tho.
[17:33:56] <unfy> interesting inversion of principle :D
[17:34:14] <Connor> I've got at 4" on R8 I can use. :)
[17:34:37] <PetefromTn_> how does the chuck attach to the shank?
[17:35:40] <Connor> The shank is part of a flat plate.. and the chuck bolts the flat plate. I think it has a boss too.. because I can't get it off even after removing the bolts..
[17:36:37] <PetefromTn_> so it is not a typical mount like for a boring head or something
[17:37:30] <Connor> http://www.ebay.com/itm/4-3-JAW-R8-COLLET-CHUCK-/290965241705?pt=LH_DefaultDomain_0&hash=item43bee13f69

[17:38:38] <Connor> here you go.
[17:38:58] <Connor> Must be out of stock.. they have the price at 1134.95 ROFL
[17:39:15] <PetefromTn_> WOW
[17:39:22] <unfy> yeah i was a bit O_o
[17:39:34] <Connor> It's not that much.. it's like $99.00 or so..
[17:39:49] <PetefromTn_> I am sure
[17:39:56] <Tom_itx> is the R8 collet attached to a backplate?
[17:40:00] <PetefromTn_> probably 113.49
[17:40:00] <Tom_itx> or part of..
[17:40:26] <Connor> they jack the price up when out of stock instead of removing the listing.. I can't find it on normal site..
[17:40:31] <SpeedEvil> PetefromTn_: if they actually say they are out of stock, then they need to close the listing
[17:40:38] <SpeedEvil> More than 10 available / 36 sold
[17:40:47] <SpeedEvil> if they close the listing - they lose that '36 sold'
[17:40:48] <Connor> Tom_itx: The R8 shank IS part of the backplate..
[17:41:12] <Tom_itx> might be a cheap way to get a 3jaw for my little lathe
[17:41:29] <PetefromTn_> who cares it is a ridiculous price and I can't use it anyways hehe
[17:41:37] <Connor> I've got a 3" on the lathe.. 4" on the rotary table, and the R8 4"
[17:41:53] <Connor> http://www.ebay.com/itm/3-INCH-5C-MOUNT-FOR-3-4-JAW-SELF-CENTERING-LATHE-CHUCKS-3900-4703/231314095633?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D27538%26meid%3D7de8a7a732b5438b8c3e87c0c020c72a%26pid%3D100005%26prg%3D11353%26rk%3D4%26rkt%3D6%26sd%3D331114009913&rt=nc
[17:42:04] <Connor> basically one of those.. except R8
[17:42:07] <Tom_itx> or use that as a beginning for a rotary table
[17:44:04] <PetefromTn_> I can get a cat40 ER40 and use up to 1 3/16 accurately held

[17:54:12] <Connor> up. 2 kids and 1 adult dead
[17:54:15] <Connor> err. yup..
[18:02:07] <unfy> :(
[18:27:01] <roycroft> i have to machine some ceramic insulators
[18:27:09] <roycroft> is diamond grit tooling my only option?
[18:35:05] <_methods> yeah pretty much
[18:36:35] * roycroft was hoping silicon carbide might do it, but is dubious
[18:37:08] <roycroft> i just had a brilliant idea though - pottery kiln furniture
[18:37:17] <roycroft> which i think i can get in the exact size i need
[18:37:18] <_methods> man that stuff is a nightmare
[18:37:24] <_methods> tooling is expensive
[18:37:30] <Jymmm> http://www.google.com/search?q=do+a+barrel+roll
[18:38:05] <roycroft> i need to thermally isolate a burner assembly that gets up to about 300c from the rest of my brew stand
[18:38:34] <_methods> ceramic inserts
[18:38:39] <_methods> ceramic washers
[18:38:55] <roycroft> i'm thinking of some 1"x1" kiln posts
[18:38:56] <_methods> stack them up to give you enough clearance for thermal break
[18:39:01] <roycroft> they are hollow in the center
[18:39:05] <_methods> yeah
[18:39:14] <roycroft> i can weld a stud to the brew stand and to the burner assembly
[18:39:25] <roycroft> and set the insulator on the brew stand stud and set the burner on top of it
[18:39:28] <roycroft> that would work fine
[18:39:29] <_methods> you can get the ceramic washers for a decent price on mcmaster
[18:39:44] <_methods> they're a bit spendy but not too horrible
[18:39:45] <roycroft> i can get the kiln posts at a local pottery supply store for about $1.25 each
[18:39:55] <_methods> hell that's a no brainer
[18:40:06] <_methods> try it with the posts and if it doesn't work shift frie
[18:40:13] <_methods> s/frie/fire
[18:40:15] <roycroft> http://www.amazon.com/Inch-Kiln-Posts-Set/dp/B0078G460O/ref=sr_1_2?ie=UTF8&qid=1417566003&sr=8-2&keywords=kiln+posts
[18:40:29] <roycroft> stuff like that
[18:40:48] <roycroft> my brew stand is made of 1"x1" square tubing, so they would sit on top perfectly
[18:41:09] <roycroft> so i think i should go buy some of those before the store closes
[18:41:19] <Jymmm> https://www.google.com/search?q=askew&gws_rd=ssl
[18:41:19] <roycroft> and perhaps do a bit of fabrication tonight
[18:42:06] <Jymmm> https://www.google.com/search?q=zerg+rush
[19:15:52] <_methods> wow talk about making something more complicated than it has to be
[19:16:03] <_methods> all that madness to make an ark
[19:16:09] <_methods> arc even
[19:27:04] <unfy> was building an electric shop furnace 9 months ago ... but things happened ._.
[19:31:30] <roycroft> well they went up in price
[19:31:37] <roycroft> they're $1.45 now
[19:31:43] <roycroft> but i blew the budget and got them anyway
[19:32:04] <roycroft> one only lives once (per lifetime at least)
[20:35:12] <jfigie> cradek ?
[20:39:33] <jfigie> I have a SEM DC servo motor with tach that works better in one direction than the other. cradek suggested that the issue may be the tach. I took the motor off the machine and scoped the tach output. I used a hand drill to spin the motor. The output is noisy in both directions but maybe 2 times worse in the direction that was giving me trouble (CW).
[20:39:51] <jfigie> Now I need to figure out how to fix the tach.
[20:40:11] <jdh> clean the brushes
[20:40:37] <jfigie> Here is a view https://drive.google.com/file/d/0B2fj8HWg0FnNOHkxSlFIVzkyRU0/view?usp=sharing
[20:40:56] <jfigie> I cleaned up the carbon dust
[20:41:12] <jfigie> but it is a little oily inside still
[20:41:29] <jfigie> how do you clean the brushes?
[20:41:41] <jdh> if the brush holders aren't centered, they will wear oddly and catch one direction
[20:42:37] <jdh> take them out, clean everything. make sure the springs work
[20:42:45] <jfigie> OK but what about the commutator segments? How smooth do they need to be?
[20:42:47] <jdh> clean up the armature edges if needed
[20:42:55] <jdh> err...commutator
[20:43:18] <jdh> I have no way to quantify that
[20:43:28] <jfigie> I checked the springs by pushing each brush up with an xacto
[20:44:12] <jdh> pull it out and deglaze the segments?
[20:45:42] <jfigie> ok armature segments. I will take it apart further. I just did not want to take it apart more than necessary
[20:46:24] <jdh> commutator segments
[20:48:13] <jfigie> So after cleaning up the commutator in a lathe? Do I need to do anything to the brushes? will they just quickly wear back to the right shape?
[20:49:46] <jdh> I have usually spun the motor with a drill or whatever to reshape the brushes and then blow out the carbon
[20:50:38] <jfigie> OK thanks. I will proceed from here.
[20:51:53] <jfigie> Maybe some new gaskets to keep the oil out. The motor is about 27 years old.
[21:49:15] <PetefromTn_> Damn I love craigslist..
[21:49:22] <XXCoder> yeah?
[21:49:27] <PetefromTn_> yeah
[21:49:30] <jdh> W4WM?
[21:49:46] <XXCoder> found something>
[21:49:54] <PetefromTn_> I ripped out all that old AC unit shit and all the old sheetmetal
[21:50:01] <PetefromTn_> had it all sitting in my driveway
[21:50:06] <PetefromTn_> wanted it GONE
[21:50:19] <PetefromTn_> someone is supposed to be coming to look at my house for sale in the morning
[21:50:25] <PetefromTn_> took a couple pictures
[21:50:33] <PetefromTn_> posted a free ad on craigslist
[21:50:38] <PetefromTn_> come get it ALL or none
[21:50:48] <jdh> scrap metal would bet picked up in 10 mins here
[21:50:51] <PetefromTn_> half an hour later and my driveway is CLEAN!!
[21:51:14] <jdh> and they are happy too
[21:51:25] <PetefromTn_> even got a phone number from the nice guy that came to pick it up for a Tile install guy that he recommended during our conversation.
[21:51:30] <PetefromTn_> yeah they were pretty happy.
[21:51:43] <PetefromTn_> I would normally try to recycle that shit myself
[21:51:54] <XXCoder> just bad timing
[21:51:55] <PetefromTn_> but I don't have the time right now
[21:52:32] <PetefromTn_> SO I am happy it is all gone and I can concentrate on cleaning up the yard from leaves and stuff and clean up the house inside for their visit.
[21:52:45] <PetefromTn_> With my luck I will do all of this and they won't show up again
[21:52:53] <PetefromTn_> had that happen a couple times now
[21:52:57] <PetefromTn_> asshats
[21:54:48] <PetefromTn_> I cannot tell you how nice this new AC unit is. SOOO quiet and so far it seems to barely run to keep the house nice and warm. I am so pleased. Plus it is one less annoyance to chalk off the list of things the house needs finished to be completed
[21:54:58] <PetefromTn_> hopefully it will help me sell it soon.
[21:55:15] <jdh> my old ones would run about 20hours a day in the summer
[21:55:23] <jdh> new ones are much better
[21:55:42] <PetefromTn_> yeah this one is not some state of the art thing but compared to what I had it is MUCH better LOL.
[21:55:54] <XXCoder> probably better effecentivty
[21:56:00] <XXCoder> less power for more bac
[21:56:11] <jdh> replaced both of mine last year. old ones were from 1992?
[21:56:25] <PetefromTn_> shits expensive huh
[21:56:32] <jdh> not really.
[21:56:46] <PetefromTn_> it is to me man..
[21:56:51] <PetefromTn_> and I got a great deal
[21:57:13] <jdh> friend with hvac company needed to keep his guys busy so I got it at cost + their labor
[21:57:59] <PetefromTn_> Once I get to Florida I will have that kinda setup. My best friend for years does AC work. He already has done similar for my other best friend and family members. Wish he was closer
[21:58:29] <jdh> he would be if you hadn't run off and left him for teh backwoods
[21:58:47] <PetefromTn_> yeah right what the Frack was I thinking???
[21:59:01] <jdh> guess where I'll be in 3.5 weeks
[21:59:21] <PetefromTn_> yeah I know you might as well live there it seems
[21:59:44] <PetefromTn_> Tell you what if I get my house sold we are gonna need to do some diving together man LOL
[22:00:14] <Connor> I better get my stuff done before you do sell the house.. Huh?
[22:00:36] <PetefromTn_> might be a good idea for us to finish my toolchanger too LOL
[22:00:38] <PetefromTn_> but yeah
[22:00:53] <PetefromTn_> been following that WJ200 thread today
[22:01:06] <PetefromTn_> gotta figure out how to get orient working here somehow.
[22:01:20] <PetefromTn_> that is really the only thing holding us back from the toolchanger setup.
[22:02:09] <XXCoder> heh would love to have toolchanger but my cnc simply cant be used with it
[22:03:31] <Connor> If there was better documentation and examples of the component.. it would be that big of a deal.
[22:04:14] <PetefromTn_> well apparently there are several people using it now so maybe there will be soon.
[22:04:40] <Connor> Someone did get it working.. and supposedly sent his stuff to who ever maintains the wiki.. not sure if it made it on yet or not.
[22:07:40] <PetefromTn_> I think I want to get rid of my fish tank man...sigh
[22:07:54] <XXCoder> fish tank man. sounds weird. lol
[22:08:08] <PetefromTn_> my last guppy died yesterday
[22:08:16] <PetefromTn_> all that is left is the plecostamus
[22:08:22] <PetefromTn_> and he is a hearty little guy
[22:08:33] <XXCoder> or it has connections to mafia.
[22:08:33] <PetefromTn_> but I am kinda over the goldfish dying
[22:09:09] <PetefromTn_> besides if we move I am not gonna be taking it with us that would be a beotch
[22:09:22] <XXCoder> big ass tank eh
[22:09:30] <PetefromTn_> no not really
[22:09:40] <PetefromTn_> I cannot remember how many gallons it is
[22:09:51] <PetefromTn_> probably 30 or something like that
[22:10:26] <XXCoder> actually its possible to just put fish in larg-ish plastic bag. when you fill tank with fresh water put bag in it for while to balance out then release
[22:10:47] <XXCoder> but since youre basically done its better just to sell it or something
[22:10:55] <PetefromTn_> yeah but moving to florida with fish in a bag is probably not gonna work
[22:11:07] <XXCoder> or pull it apart and make cool glass designs with cnc
[22:11:15] <XXCoder> yeah
[22:20:58] <CaptHindsight> 102F and climbing
[22:21:06] <XXCoder> ?
[22:23:30] <CaptHindsight> what the thermometer says
[22:35:31] <XXCoder> on what? your kiln? your body?
[22:46:16] <Connor_iPad> CaptHindsight: What thermometer?
[22:59:35] <unfy> plecos usually are hearty
[23:00:44] <unfy> but yeah, a gradual water mixing and stuff is usually good. put the bag in the tank (still closed) for a while to slowly balance temp, then add in a bit of tank water every 5min for a while and then finally dump them ... or something.
[23:00:50] <unfy> or, just give them to your cats :D
[23:09:48] <PetefromTn_> yeah well like I said just probably should let it go to someone else who wants it. Its a nice tank actually.
