[03:44:21] <Loetmichel> mornin#
[07:20:04] <jthornton> dang I need safety glasses to eat this grapefruit
[07:35:21] <s1dev> jthorton, nah, just a bulletproof vest :P
[08:08:40] <R2E4> Good morning all.
[08:33:20] <r00t4rd3d> morning yes, good no.
[08:34:00] <jdh> it's a fine morning.
[08:34:15] <r00t4rd3d> for wood.
[08:34:28] <r00t4rd3d> I need to cut some.
[08:34:34] <R2E4> I'm finding it wuite nice especially after my new purchase......
[08:34:52] <R2E4> hitachi vm40.....
[08:40:23] <AR_> you use it to cut wood?
[08:41:13] <AR_> R2E4, how much did it cost
[08:41:33] <R2E4> 4000.00
[08:42:18] <AR_> not bad
[09:07:22] <alex_joni> jthornton: depends on the eating speed
[09:09:27] <JT-Shop> lol
[09:37:43] <JT-Shop> Tom_itx: what do i neet to program this? http://cq.cx/ladder-tutorial.pl
[09:39:28] <AR_> perl
[09:39:53] <AR_> oh i thought it was a perl file
[09:40:00] <R2E4> I have a pic programmer
[09:40:14] <AR_> yeah you need a PIC programmer
[09:40:48] <JT-Shop> ok
[09:41:44] <JT-Shop> like this? https://www.sparkfun.com/products/9671
[09:42:34] <R2E4> yup
[09:43:03] <R2E4> You'll need the mplab enviroment software
[09:43:18] <R2E4> Looks like it comes in that kit'
[09:46:28] <JT-Shop> download it from here? http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en019469&part=SW007002
[09:47:15] <R2E4> yes
[09:47:29] <JT-Shop> thanks, this is all new to me
[09:48:33] <jdh> seems pricey for a pic programmer
[09:50:14] <Jymmm> "From the "MPLAB IDE" directory on the included CD...."
[09:50:24] <JT-Shop> ah ok
[09:51:21] <jdh> guess it is reasonable for a USB one vs. ancient p-port versions
[09:51:48] <JT-Shop> I guess this is my sign "Standalone windows programming software fully supported by Microchip is included."
[09:52:44] <R2E4> It comes in that kit you posted, or youcan download it free. The programmer is only 69.00 or something like that.
[09:53:31] <JT-Shop> or this one? https://www.adafruit.com/products/462
[09:53:53] <jdh> it's for AVRs
[09:54:01] <JT-Shop> ok
[09:54:02] <R2E4> that doesn't do pic chips
[09:55:22] <R2E4> http://www.canakit.com/usb-pic-programmer.html?gclid=CPf66t7OmrYCFVSVMgodAhAArw
[09:55:31] <R2E4> getting cheaper
[09:56:02] <Jymmm> http://www.electronickits.com/kit/complete/prog/ck1708.htm
[09:56:19] <R2E4> depends on which pic chip you are using, some programmers only program certain chips, depends ont he number of oins, so make sure you check that.
[09:56:26] <jdh> http://www.alliedelec.com/search/productdetail.aspx?SKU=70045451
[09:56:42] <JT-Shop> ok
[09:56:59] <Jymmm> Open source http://usbpicprog.org/
[09:57:08] <JT-Shop> the one from sparkfun said it does all of the pic chips
[09:57:44] <Jymmm> 20 euro http://usbpicprog.org/?page_id=18
[09:57:53] <jdh> http://electronics4dogs.blogspot.com/2011/07/ldmicro-and-arduino.html
[09:58:03] <jdh> or that, and avoid the PIC
[09:58:40] <Jymmm> JT-Shop: linux http://usbpicprog.org/?page_id=16
[10:00:27] <Jymmm> Junk box http://www.incrediblediy.com/2011/07/homemade-usb-pic-programmer-pickit2.html
[10:00:53] * JT-Shop wonders how many tabs I can open at once LOL
[10:01:22] <R2E4> As many as you want, until it crashes....hehe
[10:01:42] <R2E4> \http://www.rentron.com/myke4.htm
[10:01:46] <archivist> firefox gets a bit bloated when over 100
[10:02:07] <JT-Shop> this is chrome
[10:02:28] <Jymmm> JT-Shop: $1 http://pic-diys.blogspot.com/2013/03/simple-pic-programmer-for-less-than-1.html
[10:03:07] <Jymmm> JT-Shop: 10 Euro http://www.p10link.net/plugwash/picsquirt/
[10:03:08] <R2E4> haha, less than a dollar. Beat that one....hehe
[10:04:21] <Jymmm> R2E4: the junkbox one above
[10:04:43] <Jymmm> another open source usb pic prog http://openprog.altervista.org/OP_eng.html
[10:21:09] <jdh> http://www.contactandcoil.com/automation/industrial-automation/the-controls-engineer/
[10:45:04] <c60> Morning,
[11:04:09] <L84Supper> 24" rotary air bearing table minus the motor, tach and slip ring for $2800 http://tinyurl.com/dyl9bu2 a real deal, but who has a machine big enough for it?
[11:04:58] <syyl> thats nothing for a minimill ;)
[11:05:07] <c60> much to my suprise when I rebooted my machine this morning, the spindle is turning on and off via linuxcnc with the pdmx 107, but it's still not tracking the pwm for speed, I'm starting to suspect it's a setting in the vfd
[12:01:19] <c60> I wish these vfd's had better manuals,
[12:10:20] <Loetmichel> c60: what manuals? on my chinese vfd for the HF spindle was a sticker "do not tamper with, preconrfigured at factory for the 800W Spindle" ... and NO paperwork at all
[12:10:32] <Loetmichel> (and no file, either)
[12:11:39] <c60> some cheap thing from automation technologies, 2.2kw
[12:13:19] <c60> there is some jumper that is not mentioned in the manual that says vi/vr
[12:14:19] <c60> I had it working with a potentiometer but now I'm trying to control it via linuxcnc ->pmdx126->pmdx107, at least now it's starting and stopping and changing directions, just not follwing speed
[12:15:29] <jdh> http://www.woodworkforums.com/f170/tips-newbie-huanyang-vfd-users-96380/index22.html#post1417115
[12:15:33] <jdh> might be useful
[12:27:06] <c60> unfortunately my jumper was already in the vi position,
[12:31:24] <c60> Yeah, it's alive, just needs scaling now,
[12:58:57] <IchGuckLive> hi all
[12:59:42] <c60> good day
[13:00:05] <IchGuckLive> hi
[13:00:22] <IchGuckLive> C60 is a good steel
[13:00:32] <IchGuckLive> O.O B)
[13:00:46] <c60> it's a steel?
[13:01:17] <archivist> it is a cassette size
[13:01:51] <c60> It's mostly a buckyball to me
[13:01:58] <c60> among other things
[13:03:14] <IchGuckLive> in germany Europ C60 is a steel type
[13:04:17] <c60> there's really supposed to be a subscript there,
[13:08:12] <IchGuckLive> what is bucky ? c60
[13:09:04] <c60> A buckyball, 4th state of carbon, 60 carbon atoms bonded in a sphere, named after buckminsterfuller, foundation of nano technology,
[13:09:25] <JT-Shop> Tom_itx: are you around?
[13:09:27] <c60> strength of diamonds but flexible, or carbon fiber but flexible on all dimensions
[13:09:59] <c60> and if you take a buckyball and put gold on some vertices it becomes a inverter or other basic computing bit.
[13:10:48] <c60> there's also some research utilizing it for delivery of radioactive imaging isotopes, basically they put the isotope inside a buckyball and it goes through your body, but unlike the isotope your body knows what a buckyball is and shits it out.
[13:11:15] <c60> nanotubes, basically elongated buckballs, with no top or bottom.
[13:11:43] <c60> http://c60.ca my website of rambling,
[13:12:29] <c60> sweet, spindle control from linuxcnc achieved with proper speed following.
[13:16:26] <JT-Shop> to power a PIC in the field from a 24vdc power supply would a LM7805 with 1A output be ok?
[13:17:24] <archivist> should be
[13:17:24] <JT-Shop> and what does voltage dropout mean?
[13:17:32] <JT-Shop> http://www.digikey.com/scripts/dksearch/dksus.dll?FV=fff40027%2Cfff80182&k=7805+voltage+regulator&vendor=0&mnonly=0&newproducts=0&ptm=0&fid=0&quantity=0&PV69=80
[13:17:37] <cpresser> JT-Shop: depends :)
[13:17:50] <cpresser> LDOs have a minimum volate drop (eg input-output-voltage)
[13:18:06] <archivist> the poor 7805 gets hot if dropping too much
[13:18:06] <JT-Shop> I've seen some circuits that use a LM7812 then a LM7805 to get to 5vdc
[13:18:33] <JT-Shop> so better to go 7812 > 7805
[13:20:01] <archivist> I have never used two regs like that but it would share the power wastage
[13:21:23] <cpresser> how much power will you draw?
[13:21:26] <cpresser> just the controller?
[13:21:39] <JT-Shop> a PIC chip and a couple of optos?
[13:22:04] <cpresser> okay, that should be well below 50mA. Times 20Volts == 1Watt Heat generated in the 7805
[13:22:15] <cpresser> get a heatsink and you are okay
[13:22:22] <JT-Shop> ok, cool
[13:22:52] <pcw_home> a normal PIC (not DSPIC) will only be say 10 mA or so
[13:22:56] <archivist> is the 24v stabilised or a rough approximation
[13:23:06] <JT-Shop> are there input optos and output optos
[13:23:20] <JT-Shop> it is from a 24vdc power supply
[13:23:28] <pcw_home> so you need to add the max OPTO LED current
[13:23:39] <L84Supper> c60: any relation? http://www.steelnumber.com/en/steel_composition_eu.php?name_id=154
[13:24:31] <JT-Shop> this is the power supplies we use http://www.carlogavazzisales.com/pspdfs/datasheetSPD60W.pdf
[13:25:06] <pcw_home> for slow stuff you can get by on less than 1 mA for a PIC (more if you need xtal osc timing accuracy)
[13:25:06] <IchGuckLive> for power in a real board better to use mc34063A
[13:25:38] <JT-Shop> this is like one input per second max
[13:26:05] <pcw_home> How accurate is the timing required to be?
[13:26:07] <JT-Shop> just have to count to 100 or something like that and turn on an output
[13:26:57] <JT-Shop> I'm just counting each time the tilting bucket changes states in a rain gauge
[13:27:05] <JT-Shop> so real slow
[13:27:36] <pcw_home> OK so no xtal just a PIC and a couple OPTOS
[13:27:38] <JT-Shop> yes
[13:29:15] <JT-Shop> IchGuckLive: thanks for the tip on the MC34063AP
[13:29:16] <pcw_home> maybe a 8 pin PIC would have enough I/O
[13:29:57] <L84Supper> http://www.mouser.com/ProductDetail/RECOM-Power/ROF-78E50-05SMD-R/?qs=sGAEpiMZZMtwaiKVUtQsNWiU%2fn%252bYYHKMUYS0P1vLJVE%3d
[13:30:29] <L84Supper> $3.76 DC - DC switcher 5V out 500ma
[13:30:45] <JT-Shop> can't beat that
[13:31:14] <IchGuckLive> NP
[13:31:17] <L84Supper> then you don't have to worry about input or output caps or anything else
[13:31:29] <L84Supper> or heat sinks
[13:31:34] <pcw_home> But you only need 1 mA plus whatever the OPTOS need
[13:32:19] <L84Supper> it's only $3.76 for the whole thing
[13:32:32] <JT-Shop> I don't know where to start for optos
[13:33:06] <pcw_home> Does the I/O need to be isolated from the 24V?
[13:34:22] <JT-Shop> hmm I don't know, the 24v powers up the text messaging thing and it has 24vdc sinking inputs
[13:34:27] <JT-Shop> IIRC
[13:34:43] <L84Supper> http://www.mouser.com/ProductDetail/RECOM-Power/RBL-1205S-E/?qs=sGAEpiMZZMtwaiKVUtQsNXYYRYMm%252bq33LghJMB36PWs%3d
[13:34:59] <L84Supper> isolated version for $5.97
[13:35:14] <L84Supper> oh wait thats up to 12V in
[13:35:59] <L84Supper> http://www.mouser.com/ProductDetail/Cincon/EC1SA21N-S/?qs=sGAEpiMZZMtwaiKVUtQsNVinBSFi1TTftVwfm7u5c7o%3d
[13:36:26] <L84Supper> a bit more $9.62 or use the non isolated supply + opto's
[13:36:42] <pcw_home> So maybe you dont need OPTOs or isolation, just dividers on inputs and MOSFETs on outputs
[13:37:07] <JT-Shop> well the input can be a 5v reed switch actually
[13:37:30] <pcw_home> the bucket switch?
[13:37:37] <JT-Shop> yes
[13:38:39] <JT-Shop> so really I just need to turn on and off the 24vdc input
[13:39:49] <pcw_home> well just one darlington OPTO will do that so still less than 5mA total so a 7805 would be just fine
[13:40:25] <JT-Shop> ok, got a number for the OPTO?
[13:41:26] <L84Supper> can you use an opto-isolated relay? SSR? http://www.mouser.com/ProductDetail/Clare/CPC1217/?qs=sGAEpiMZZMtJb2UpDWIubW29ERzDkclq
[13:41:33] <L84Supper> $1.39
[13:41:39] <pcw_home> SMD or through hole
[13:41:57] <JT-Shop> through hole
[13:42:02] <JT-Shop> so I can breadboard it
[13:42:15] <JT-Shop> I need to make a prototype
[13:43:18] <JT-Shop> something like this? http://www.digikey.com/product-detail/en/4N32/4N32VS-ND/1738520
[13:43:47] <pcw_home> do you need more than one output?
[13:44:09] <JT-Shop> no, I just have to switch on and off one input
[13:47:52] <pcw_home> That should be fine
[13:48:16] <JT-Shop> thanks
[13:48:50] <pcw_home> A little higher voltage might be better (30 is not much more than 24)
[13:52:36] <tjb1> I hear from a teacher that Seco will probably be calling me :D
[13:53:15] <pcw_home> http://www.digikey.com/product-detail/en/MOC8021M/MOC8021M-ND/1793973
[13:53:15] <pcw_home> is a 50V one
[13:53:51] <JT-Shop> thanks
[14:05:21] <IchGuckLive> SOMEONe kows if qcad can reorder the sketch lines so it is closed
[14:09:35] <JT-Shop> not that I know of but sheetcam can jump gaps if you tell it to...
[14:09:41] <skunkworks> can you turn it into a polyline?
[14:09:59] <skunkworks> http://qcad.org/doc/qcad/2.2/reference/en/chapter21.html
[14:10:05] <IchGuckLive> thanks
[14:10:21] <IchGuckLive> sheetcam is this also free atubuntu
[14:11:43] <tjb1> JT-Shop: I will have full version of sheetcam thursday :D
[14:11:47] <IchGuckLive> i stay with my Heeks its free and i can do the PIMP at my self
[14:12:35] <JT-Shop> tjb1: you going to work for Hardinge?
[14:12:54] <tjb1> JT-Shop: Not sure, tour got moved to next wednesday
[14:13:04] <tjb1> They told me the first step to getting a job there was to tour the plant so maybe?
[14:13:53] <JT-Shop> at least your at step 1
[14:14:22] <tjb1> I spoke to Haas about being a service engineer and I have no idea what I would do at Seco
[14:14:45] <JT-Shop> sell inserts
[14:16:02] <tjb1> They said at the career fair about getting prints and then building a process for the customer
[14:16:11] <tjb1> What tooling, inserts, speeds and feeds, etc...
[14:26:13] <jdh> if you run across any spare inserts...
[14:35:15] <JesusAlos> hi
[14:37:15] <JesusAlos> http://imagebin.org/251715
[14:37:24] <JesusAlos> have a problem with machine
[14:37:42] <JesusAlos> the trajectory create a circle
[14:37:53] <JesusAlos> when change direction
[14:39:12] <cradek> http://www.linuxcnc.org/docs/html/gcode/gcode.html#sec:G61-G61_1
[14:39:32] <skunkworks> aww - I was just about to post that...
[14:39:42] <JT-Shop> http://www.linuxcnc.org/docs/html/common/User_Concepts.html
[15:29:25] <tjb1> Ehh Seco just called...
[15:29:31] <tjb1> 10 week internship at $15 an hour
[15:32:26] <JT-Shop> cool
[15:36:49] <tjb1> Probably can't live in Troy, Michigan for $15 an hour.
[15:41:50] <tjb1> What do you think JT-Shop?
[15:51:56] <L84Supper> tjb1: they pay you or you pay them? :)
[15:52:09] <tjb1> They pay me $15 an hour
[16:04:44] <t12> supermicro :(
[16:04:58] <t12> sled id's not matching slot id's and identify not working :(
[16:05:50] <t12> or maybe just sas addrs not matching?
[16:05:51] <t12> confusion
[16:19:53] <tjb1> Just got an email from seco, they provide housing and vehicle...
[16:19:56] <tjb1> Looking better
[16:46:03] <r00t4rd3d> doing what
[16:46:54] <AR__> where can i get cheap small endmills/drills?
[16:47:00] <AR__> i think someone linked me to a good ebay seller
[16:47:04] <AR__> but i forgot it

[16:51:26] <AR__> $10 for that piece of shit
[16:51:55] <r00t4rd3d> i see your new to buying good bits
[16:52:06] <r00t4rd3d> 10 aint shit
[16:52:09] <r00t4rd3d> buy some onsurd bits
[16:52:16] <r00t4rd3d> 10 is cheap
[16:52:19] <AR__> i want cheap shit bits
[16:52:23] <r00t4rd3d> they are great bits too
[16:52:35] <r00t4rd3d> cheap bit burn and break
[16:52:50] <JesusAlos> i
[16:52:51] <JesusAlos> hi
[16:52:58] <r00t4rd3d> oh jesus
[16:53:08] <AR__> hi jesus
[16:54:49] <r00t4rd3d> http://www.ebay.com/itm/ONSRUD-CUTTER-ROUTER-BIT-PCL400031-1-4-/300611882765?pt=LH_DefaultDomain_0&hash=item45fddd4f0d
[16:55:19] <r00t4rd3d> thats a good price
[16:56:12] <r00t4rd3d> 10 for $80
[16:56:15] <r00t4rd3d> http://www.ebay.com/itm/ONSRUD-CUTTER-ROUTER-BIT-PCL400031-1-4-QTY-10-/290621674777?pt=LH_DefaultDomain_0&hash=item43aa66d519
[16:56:35] <mozmck> I used an onsrud spiral bit, but was not terribly impressed. I was routing end grain hardwood, and it did not make as smooth a cut as I thought it should.
[16:57:14] <r00t4rd3d> have you used a bit that does make it smooth?
[16:57:17] <r00t4rd3d> i havent
[16:57:49] <mozmck> so I bought an import solid carbide endmill from MSC for a few dollars ($6 or $8 I think), and it worked much better.
[16:57:59] <r00t4rd3d> lol
[16:58:40] <mozmck> it's true! I would never buy a "spiral" router bit again if I can get the same size in an endmill.
[16:58:44] <r00t4rd3d> i use my .125 solid carbides on everything
[17:00:38] <mozmck> This was routing about 1" deep endgrain, just taking off a hair to true up the ends of pieces that were to be glued into a ring.
[17:00:52] <mozmck> So it had to be perfect.
[17:08:20] <r00t4rd3d> http://www.ebay.com/itm/New-1-4-5-Flute-High-Performance-Carbide-End-Mill-w-AlTiN-/190752133747?pt=LH_DefaultDomain_0&hash=item2c69b69273
[17:08:27] <r00t4rd3d> bet that cuts good
[17:09:52] <r00t4rd3d> all them flutes would help smooth the edges i think

[17:24:37] <DaViruz> http://imgur.com/cQLQ2f8
[17:24:44] <DaViruz> one step closer to digitized lathe threading!
[17:25:13] <DaViruz> the hard part remains, the mechanical part..
[17:33:30] <JesusAlos> what G trajectory mode is best for cut circles?
[17:44:15] <andypugh> Firstly, are you sure that your machine can't handle higher accell values?
[17:49:23] <JesusAlos> no. i'm not sure
[17:51:01] <andypugh> Unless your machine is cutting very fast that image seemed to show really excessive rounding.
[17:55:18] <JesusAlos> yes, machine cutting very speed.
[17:55:56] <JesusAlos> but don't understand wy linucnc can't adjust the speed
[17:56:56] <JesusAlos> don't linuxcnc reduce speed to optim value?
[17:57:15] <andypugh> It can do, if you tell it to.
[17:57:51] <andypugh> But "optimum" means different things to different people
[17:59:54] <JesusAlos> so, must use G61 or G64 commands?
[18:07:43] <andypugh> I don't know. I have never noticed any problems with the parts I make, so I don't know what settings I am even using.
[18:08:23] <andypugh> What are your axis max velocity and accelleration settings?
[18:16:17] <JesusAlos> Don't know now
[18:16:24] <JesusAlos> tomow see
[18:21:58] <andypugh> Is this a servo or stepper machine?
[18:33:00] <JesusAlos> stepper
[18:34:44] <andypugh> Metric or Imperial setup units?
[18:37:40] <JesusAlos_> z
[18:44:47] <JesusAlos> gn
[18:51:16] <JT-Shop> you gotta sit still http://imagebin.org/251736
[18:52:01] <andypugh> What is he?
[18:52:09] <andypugh> He looks foreign.
[18:52:10] <JT-Shop> tufted titmouse
[18:52:16] <JT-Shop> he is
[18:52:21] <JT-Shop> he is american
[18:52:47] <JT-Shop> they seem to be the only local birds that love peanuts
[18:53:56] <andypugh> These were in my garden making a noise today: http://en.wikipedia.org/wiki/Coal_Tit they must be expecting spring. They are the only ones, it's freezing here and nobody can leav my folk's village for 10' snowdrifts.
[18:54:46] <JT-Shop> almost looks like our chickadees
[18:55:39] <JT-Shop> http://en.wikipedia.org/wiki/Black-capped_Chickadee
[18:56:24] <andypugh> They appear to be very close relatives.
[18:56:43] <JT-Shop> the bird in the photo http://en.wikipedia.org/wiki/Tufted_Titmouse
[18:56:51] <JT-Shop> yes very related
[18:57:36] <JT-Shop> they have two songs one you can hear easy and one very high pitched one that is hard to hear
[18:58:02] <JT-Shop> I can only hear the high pitched one when they are up close and in my face
[19:00:02] <andypugh> I don't think I have ever been particularly close to a coal tit. I was about 6' away today, and was surprised at the odd noise it was making.
[19:00:27] <JT-Shop> looking for a mate I suspect
[19:02:00] <andypugh> That was my guess.
[19:02:51] * JT-Shop has to slip on the chef hat now
[19:03:16] <andypugh> A bit early for laying eggs though, this year. The car said 33F today. Last year this time was 20C (67F)
[19:08:15] <JT-Shop> that's a big difference
[19:08:41] <JT-Shop> I must get started on the french onion soup so it will be ready for dinner
[19:08:44] <JT-Shop> talk to you later
[20:11:42] <Jymmm> http://www.youtube.com/watch?v=MrqqD_Tsy4Q
[21:06:46] <PCW> For some reason that led me to KPA videos
[21:10:18] <PCW> "Its time to settle final accounts with the US Imperalists"
[22:12:44] <Valen> could somebody take a look at this http://pastebin.com/cbJ84v8e
[22:13:46] <Valen> its a super simple file but for some reason it is rapiding to the origin of G54 before it then rapids again to the actual start of the cut
[22:13:58] <Valen> generally through the job and the bed and the floor
[22:17:06] <Valen> running 2.6
[22:17:17] <ReadError> is that from HSM ?
[22:17:49] <Valen> ?
[22:19:39] <Valen> ReadError, ?
