[00:08:03] <trentster> So guys- this is a non CNC related question, but what would you guys use excess solar power for in a shed or home workshop if you had it?
[00:09:53] <trentster> I have an 80W panel on the shed and a 100Amp Hour battery connected to it - at the moment I am only really using it for minimal LED lighting which is movement activated when I go into the garage. Any other suggestions as I have quite a bit of power going to waste?
[00:12:53] <Jymmm> It's not necessarily "excess" power. The moment you use it for something, you'll be draining the battery and that battery will need to be recharged.
[00:13:28] <Jymmm> 80W @ 12V = 6.7A
[00:13:48] <trentster> Jymmm: yes but there is a ton of sun here, so the solar regulator is most of the time preventing the battery from being charged as its always full.
[00:14:08] <trentster> thats why I want to use the power for something useful
[00:14:31] <trentster> especially during the day
[00:14:39] <Jymmm> 100AH / 6.7A = 14 Hours of 100% full sun to recharge the battery, and there is only one day a year where you have THAT much sun.
[00:15:21] <Jymmm> Plus, you can't discharge the battery that low else risk shortening it's overall lifetime
[00:15:29] <trentster> yes assuming a safe limit of battery drain, not reccomended to go over 60% for battery longevity there is still excess power
[00:16:26] <Jymmm> and most panels never do their full "rated" capacity.
[00:16:49] <Jymmm> Unless you are in the Mojave or something =)
[00:17:35] <Jymmm> Use it for backup winter lgihting for the house
[00:18:01] <Jymmm> Keep batteries topped off
[00:18:12] <trentster> Jymmm: playing with the numbers this is what I have thus far https://monosnap.com/file/EzdOdb8iuMASUCHHkYbtmGImnPbKIK
[00:18:33] <trentster> still trying to learn this stuff so it may not be perfectly accurate
[00:19:12] <trentster> I was thinking of maybe using it to generate hydrogen from water during the day or for electroplating or something else useful
[00:19:47] <Jymmm> Um why do you have it at all in the first place?
[00:20:34] <trentster> I wanted to learn about solar plus - have some kind of mini-backup
[00:20:49] <Jymmm> ah
[00:21:23] <trentster> but it irks me to think of the watts going to waste every day just to keep a battery topped up that hardly gets used
[00:21:41] <Jymmm> do you have a well pump?
[00:22:07] <Jymmm> fans that run constantly?
[00:22:55] <Jymmm> ham radio?
[00:23:14] <trentster> nope literally at the moment just some 12V stuff I use intermittently, like lights that come on when I go into the garage, extraction fan for soldering station, and lighting above soldering station.
[00:24:13] <trentster> I also have a server cabinet in there, and will probably put some 12V fans at the top connected to a temperature sensor that closes the circuit when the temp inside cabinet gets hot.
[00:25:29] <trentster> So in essence at the moment the only power which is really used is a Led light strip that is on when I am working on cnc stuff which uses 5.1W when on
[00:25:50] <trentster> I probably average about 20 hours a week of usage with it
[00:27:20] <Jymmm> cooling in the summer is a perfect usage for solar
[00:27:50] <trentster> yeah - besides a fan how else do you use it for cooling?
[00:28:07] <trentster> Aircon is obviously not practical - it uses ridiculous ammounts of power
[00:33:27] <trentster> anyway - I will carry on pondering some inventive uses, thanks for the input
[00:37:31] <Jymmm> swap cooler depending on where you are.
[00:37:52] <trentster> ? swap cooler
[00:38:24] <ink> evaporative cooling
[00:38:38] <Jymmm> swamp*
[00:38:48] <Jymmm> or evaporative cooling
[00:39:04] <ink> basically dripping water over a mesh and pointing a fan at it as the water evaporates, it pulls heat out of the air
[00:40:51] <trentster> yup, I have hd evaporative coolers before - it would require running water, and a seperate build, but its an option - thanks for the tip
[00:41:26] <Jymmm> Or a larger reservoir instead
[00:41:53] <Jymmm> You are just recirculating the water, and topping off as needed.
[00:41:59] <trentster> or maybe just wire up some pumps to an arduino and automatically water some hydroponics or plants etc
[00:43:07] <Jymmm> Sorry, but it sounds like you are trying to find a problem to your solution.
[00:43:16] <trentster> I found a rear projection tv on the curb today and took out the Fresnal lens - I have been dying to get my hands on one. Man! that thing is seriously dangerous
[00:43:42] <trentster> a solid piece of wood bursts into flames in seconds
[00:43:51] * ink really likes the idea of solar cooling
[00:44:07] <trentster> ink: yeah me too
[00:44:18] <Jymmm> ink: Yeah, made TOTAL sense to me when running AC you have LOTS of sunlight.
[00:44:26] <trentster> gonna look into the most efficient way of doing a mini diy evaporative cooler build
[00:44:33] <ink> hehe totally
[00:44:37] <ink> zeer pots are also interesting
[00:44:51] <trentster> zeer pots?
[00:44:56] <Jymmm> oh the pots in the pots?
[00:45:04] <Jymmm> with moist sand in between
[00:45:09] <ink> basically a double-walled pot with sand between the two pots you wet the sand and it cools the inside as it evaporates
[00:45:44] <trentster> hmmm interesting
[00:46:17] <Jymmm> trentster: https://www.youtube.com/watch?v=hmb-kCcDLxQ
[00:47:05] <trentster> thanks looking
[00:52:20] <trentster> interesting
[00:52:48] <trentster> Nice survival skill to have - will jot it down in the event of a zombie outbreak ;-)
[00:55:20] <ink> hehe
[02:30:32] <Deejay> moin
[02:41:31] <Jymmm> Hi DJ
[02:47:48] <Deejay> Hi Jymmm :)
[03:47:34] <tiwake> http://phys.org/news/2015-12-tiniest-picture.html
[03:48:59] <archivist> I think IBM beats that by many years, they deposited individual atoms
[03:52:06] <archivist> https://en.wikipedia.org/wiki/IBM_%28atoms%29
[03:53:21] <archivist> I hate false claims from later workers :)
[04:20:07] <archivist> a toy http://www.ebay.co.uk/itm/Mitutoyo-FN905-Coordinate-Measuring-Machine-CMM-Renishaw-PH10T-Plus-/281886074395
[05:14:05] <jthornton> morning
[08:05:10] <ReadError> anyone used leadshine gear before?
[08:06:58] <archivist> survey type question?
[08:08:02] <JT-Shop> yes he has, but I don't think anyone is here at the moment
[08:09:35] <ReadError> eh was just curious if its decent stuff
[08:09:38] <ReadError> or chinese garbage ;(
[08:09:47] <archivist> I think many have used leadshine
[08:10:00] <malcom2073> My dads mill runs on leadshines, and his small router runs on chinese clones, both work pretty good
[08:10:30] <archivist> I think leadshine badges for others too
[08:34:06] <gregcnc> Anyone used NI DAQ in Linux?
[08:46:10] <trentster> ReadError: I use leadshines, they are pretty good specially their digital stuff
[08:48:51] <trentster> ok folks I am going to rewire all the electrical this weekend. I now have a VFD in the mix - should I wire Live from wall to go physically through an emergency stop before supply to controller or to the VFD?
[08:49:32] <trentster> My logic here is that if you press emergency stop all power to everything is cut - only issue there is there may be a limit on how many amps emergency toggle switch can handle
[08:49:46] <Tom_itx> sp/or to the /and to the VFD
[08:50:06] <Tom_itx> ever hear of a relay?
[08:50:10] <trentster> Tom_itx: ?
[08:50:19] <Tom_itx> wire the estop to a relay
[08:50:25] <Tom_itx> or 2
[08:50:44] <ReadError> trentster, their servo drivers?
[08:52:07] <trentster> Yeah I have got 2 of these relays for AC and another smaller 4 channel relay that is optoisolated for the DC stuff - not sure how to throw them all into the mix as far as best practice is concerned
[08:52:21] <trentster> ReadError: no they are stepper drivers
[08:52:52] <Tom_itx> usually by the time you realize you need to hit ESTOP, it's too late anyway
[08:53:04] <Tom_itx> then you're just sparing the damage
[08:53:15] <trentster> ReadError: this is what I have, and I can vouch those guys are good sellers and the real deal http://www.aliexpress.com/store/product/3-PCS-Leadshine-AM882-Stepper-Motor-Driver-with-Sensorless-Detection-Up-to-80VDC-8-2A-512/1452584_2046501243.html
[08:53:30] <trentster> The bundled break out board is junk, I recommend not using it
[08:54:55] <trentster> Tom_itx: I am trying to follow the wiring logic used here - altho I dont use Gecko g540's
[08:54:56] <trentster> http://www.homanndesigns.com/pdfs/EN010_V8.pdf
[08:55:29] <trentster> I have the same 2 RL-04 48Vcoil 20A SPST that is shown there.
[08:56:23] <trentster> Tom_itx: I also want to wire up external switches on the enclosure so I can power up each individually and see via rocker switch light what is on.
[08:56:58] <trentster> the spindle water pump I guess makes sense to wire direct to vfd so when vfd comes on pump is on
[08:57:04] <trentster> Agree?
[08:57:24] <Tom_itx> sounds fair
[08:58:41] <trentster> in that diagram there I just not understanding why there is 2 48V relays? is the other one there on the assumption someone is gonna control a router via it?
[09:36:48] <Erant> gregcnc: I once looked at the NI stuff when I couldn't get a 5i25.
[09:37:00] <Erant> I think it would've ended up being a pain in the ass
[09:37:31] <gregcnc> I actually want to measure
[09:37:51] <Erant> Ah. Nope, sorry :/
[09:40:06] <malcom2073> Heh, I tried to use NI DAQ in linux... gave up
[09:40:38] <malcom2073> Didn't want to pay their exhorbidant fees for using their libraries, wound up using a labjack
[09:40:53] <malcom2073> Muuuuch easier to interface with
[09:41:11] <Erant> Ooh, cutters are coming in today.
[09:41:16] <malcom2073> gregcnc: ^^ Consider if Labjack would meet your timing requirements
[09:41:37] <gregcnc> I have an old one
[09:42:00] <gregcnc> i guess they still make the U12
[09:42:27] <malcom2073> It's free to use in linux, and actually supported by the community. The NI stuff uses mono iirc
[09:42:59] <malcom2073> The NI stuff is fantastic with windows, if you already have the hardware, I suggest using a windows box
[09:46:34] <gregcnc> OK. I looked a few years back and and I don't think NI was supported on linux at all.
[09:47:18] <malcom2073> It didn't used to be, it sorta is now if you want to pay for their IDE, and deal with mono
[09:47:30] <malcom2073> Only some of the devices are supported
[10:04:40] <maxcnc> Hi all ;-)
[10:05:01] <maxcnc> last workday here in germany so now on xmas holiday
[10:06:00] <maxcnc> if there is not as always a urgent job to make :-(
[10:09:09] <maxcnc> trentster: the 882 are realy good stuff better then the 880 in longtherme use
[10:11:07] <maxcnc> pcw_home: ?
[10:18:39] <maxcnc> Bye till later
[11:06:56] <CaptHindsight> http://www.ebay.com/itm/Matsuura-760-V-2-cnc-mill-plus-free-cnc-knee-mill-Great-Deal-/262179867379 $4500 or best
[11:07:19] <ssi> damn
[11:10:06] <CaptHindsight> with tooling and extra cnc knee mill
[11:10:53] <CaptHindsight> well lots of collets and chucks
[11:11:01] <ssi> which is the important part :)
[11:11:25] <CaptHindsight> tempting
[11:12:57] <ssi> I'd be all over it if I had any way to transport them and any room left in the shop :)
[11:15:12] <ssi> that knee mill looks like a cat spindle too D:
[11:18:40] <CaptHindsight> they just don't sell around here, $3k sounds crazy low but he might end up getting stuck with them
[11:19:16] <ssi> and they're sufficiently hard to move that it limits folks like me coming up and snagging them
[11:19:32] <CaptHindsight> the knee mill might get all the offers
[11:19:40] <ssi> yeah
[11:20:09] <CaptHindsight> ~ an hours drive for me
[11:20:44] <CaptHindsight> and the two combined are 12k lbs
[11:22:00] <CaptHindsight> the most difficult part looks like getting it out of his garage
[11:23:41] <archivist> still a nice cheap toy here, but too far,heavy/no transport http://www.ebay.co.uk/itm/161914877309
[11:24:13] <CaptHindsight> nice
[11:24:35] <CaptHindsight> Travel X 1200 mm Y 650 mm Z 700 mm
[11:25:09] <archivist> I need to win the lottery
[11:32:14] <ssi> don't we all
[11:32:30] <ssi> hard to win without playing though, and I refuse to play because I won't win :)
[11:32:50] <CaptHindsight> odds are about the same either way :)
[11:33:00] <ssi> yuuup
[11:33:05] <ssi> my mom plays scratchoffs constantly
[11:33:06] <archivist> same here not played in years
[11:33:07] <ssi> and WINS A LOT
[11:33:10] <ssi> I have no idea how she does it
[11:33:21] <ssi> I watched her win at least $500 on scratchers while she was visiting for four days this weekend
[11:33:29] <ssi> and she gets 1, 5, 10k prizes regularly
[11:33:31] <ssi> couple times a year
[11:33:36] <CaptHindsight> sounds like she might be a shill for the state :p
[11:33:40] <ssi> maybe
[11:33:46] <ssi> I suspect she spends at least as much buying ticktes
[11:34:31] <CaptHindsight> I hear similar stories
[11:35:03] <CaptHindsight> and spend >$100 a week
[11:35:16] <archivist> my only gambling is ebay toys :)
[11:36:00] <ssi> I gamble on barn-find airplanes that haven't flown in 25 years :D

[11:36:39] <ssi> ooo
[11:36:42] <ssi> that's close to metoo
[11:36:54] <ssi> I wonder what's dead electrically
[11:37:58] <CaptHindsight> "child with Jacobs Ladder went wild in the control panel" :p
[11:38:47] <CaptHindsight> worth it even if the whole panel looks like toast
[11:38:51] <ssi> yeah
[11:39:24] <CaptHindsight> but another project for you
[11:39:35] <archivist> project++
[11:39:40] <CaptHindsight> I have a few here myself in pieces
[11:39:41] <ssi> which I desperately don't need :)
[11:39:50] <ssi> I just have a machine hoarding fetish
[11:39:59] <ssi> someone come take this stupid NC punch press away from me
[11:41:04] <archivist> but you need it for panel making
[11:41:15] <ssi> yeah but I don't want to convert it
[11:41:20] <ssi> and the guy never brought me the tooling for it
[11:41:25] <ssi> he said he had over a hundred dies
[11:41:29] <ssi> but I have zero of them
[11:44:24] <CaptHindsight> and at the same time people post things like this trolling for suckers http://www.ebay.com/itm/Scotle-HY-3040-4-Axis-CNC-Aluminum-Router-Machine-for-Drilling-Milling-DHL-/111832107306
[11:46:05] <CaptHindsight> http://i.ebayimg.com/images/g/~ioAAOSwHQ9WVB0A/s-l1600.jpg comes with properly marked 4th axis connector location and cable :P
[11:46:18] <ssi> lul
[11:46:31] <ssi> people buy that stuff because you don't have to be and/or pay a rigger to get it home
[11:46:33] <archivist> CaptHindsight, Accuracy/Repeatability: 0.01mm http://www.ebay.co.uk/itm/310562732677 another one
[11:46:42] <ssi> and you don't need an industrial space to run it
[11:46:52] <malcom2073> Holy hell ssi, I misread that
[11:46:59] <ssi> lolololol
[11:47:15] <CaptHindsight> t-slot madness
[11:47:53] <CaptHindsight> maybe it comes with a 10 year warranty
[11:48:04] <CaptHindsight> nope only 1 year
[11:48:25] <archivist> the warranty covers the inaccuracies
[11:48:49] <malcom2073> Holy hell that t-slot thing is expensive
[11:48:55] <malcom2073> A lot of things areshocking to me today
[11:48:56] <malcom2073> it seems
[11:49:09] <ssi> hahaha
[11:49:11] <archivist> which one
[11:50:00] <malcom2073> The 10k one
[11:50:28] <archivist> that is pounds even more of your dolla
[11:50:40] <ssi> that's absurd
[11:50:44] <ssi> is it made of magic?
[11:50:48] <archivist> total lies for the accuracy
[11:51:16] <ssi> not if it's made of magir
[11:51:17] <CaptHindsight> 10450 British Pound equals 15539.31 US Dollar
[11:51:57] <malcom2073> Hey, if someone buys it
[11:51:58] <malcom2073> meh
[11:52:01] <malcom2073> sucker born every day
[11:52:09] <archivist> the sellers reply We build using Class 5 precision rolled ballscrew, preloaded...assembled with matched sets of preloaded end bearings
[11:52:09] <archivist> Our figure have been independently verified by the worlds largest measuring machine company....we produce machines for this Company!
[11:52:16] <Erant> ssi: I got a micro mill, which'll outperform that aluminum piece of c* all day.
[11:52:18] <malcom2073> Oooo class 5!!
[11:52:21] <malcom2073> That's like, better than class 4
[11:52:27] <ssi> Erant: I don't doubt it at all
[11:52:35] <ssi> malcom2073: yeah it's at least 25% better :D
[11:52:37] <archivist> C5 cannot achieve that claim
[11:52:38] <Erant> And you still don't need an industrial space.
[11:52:58] <ssi> Erant: what did the micro mill cost you all up?
[11:53:03] <CaptHindsight> did Mach3 increase the price of their pro version or something?
[11:53:05] <Erant> Or a rigger. (Though the thing still weighs like 150lbs)
[11:53:19] <ssi> I didn't hire a rigger for my 10klb vmc :P
[11:54:16] <Erant> ssi: Euh. $700 for the mill, $400-ish for the servos, $100 for the supplies, couple hundred for the Mesa, plus various tooling and whatnot.
[11:54:28] <CaptHindsight> http://www.ebay.com/itm/MachMotion-3-Axis-CNC-Milling-Machine-Control-Retrofit-Kit-/321407780807 US $8,409
[11:54:31] <Erant> Maybe $400-$500 for assorted shit like vices and whatnot.
[11:54:41] <Erant> So around $2k total, I'd say.
[11:54:50] <ssi> Erant: yea see in my experience there's a price disparity between big machines and little machines
[11:55:19] <archivist> CaptHindsight, fishing for suckers too
[11:55:23] <malcom2073> At the auctions I go to, the smalelr it is, the more it costs
[11:55:28] <ssi> the price starts low for machines around your size, gets higher and higher up to some reasonable size, then goes way back down
[11:55:36] <ssi> malcom2073: yeah exactly
[11:55:37] <Erant> Interesting.
[11:55:56] <ssi> cause huge machines that are antiquated and need retrofit are only interesting to people like us
[11:55:58] <malcom2073> I've seen cnc knee mills go for less than $500
[11:56:03] <malcom2073> yeah
[11:56:09] <ssi> and only some of us are capable of moving, storing, setting up, and powering huge machines
[11:56:09] <malcom2073> But tabletop? Shit, won't go for less than $3k
[11:56:15] <Erant> This is the right size for my space (which is half of a 2 car garage).
[11:57:36] <Erant> And it's still Chinese, so it needs some TLC to get it to where I want it.
[11:58:36] <CaptHindsight> now that I'm looking there are all sorts of way overpriced parts on ebay, tool posts for $3K etc
[11:58:58] <ssi> I paid $1k for my hardinge HNC
[11:59:05] <CaptHindsight> add an extra zero, see what happens
[11:59:05] <ssi> and then three times that on tooling for it right out the gate
[11:59:07] <malcom2073> I paid $350 for my Clausing knee CNC
[11:59:54] <malcom2073> Oh hey ssi, I've decided I'm going to make a quill clamp to stick a router on my mill
[12:00:00] <ssi> nice
[12:00:18] <ssi> I need to find an enclosure and some connectors and start building a new control for the new knee mill
[12:01:53] <malcom2073> I have the origonal electronics enclosure I'm going to re-do for my stuff
[12:03:05] <cpresser_> I need unc 4-40 rivet nuts. anybody know a distributor for europe?

[12:04:30] <ssi> UNC 4-40?
[12:04:37] <ssi> you mean #4 size, 40tpi?
[12:04:41] <ssi> that wouldn't be UNC I don't think
[12:05:09] <ssi> hm disregard, 48tpi is UNF
[12:05:48] <cpresser_> ssi: actually i dont have a clue. "unc 4-40" is what the datasheet of the connector says.

[12:10:09] <CaptHindsight> 5 hours, isn't that like 1/2 way across Pennsylvania? :)
[12:10:17] <CaptHindsight> or just feels that way
[12:10:20] <malcom2073> Feels that way
[12:11:16] <CaptHindsight> http://www.ebay.com/itm/EDM-Machine-Eltee-Pulsitron-Sinker/181958918597 New Cumberland, Pennsylvania $1k
[12:11:37] <malcom2073> Even better, only 40 minutes away :P
[12:18:06] <gregcnc> I sorta want another http://www.ebay.com/itm/281882663902?
[12:18:47] <Jymmm> malcom2073: And you can use the cabinets for a Frankenstein move remake =)
[12:18:50] <Jymmm> movie*
[12:18:54] <malcom2073> hah
[12:19:49] <Tom_itx> cpresser_, is fastenal in uk?
[12:19:58] <Jymmm> malcom2073: see background http://movieboozer.com/wp-content/uploads/2013/10/YoungFrankenstein.jpg
[12:20:05] <malcom2073> Indeed

[12:20:50] * Tom_itx feels Jymmm has been letting us down on the morning imagery
[12:21:05] <malcom2073> I enjoyed young frankenstein
[12:21:27] <Jymmm> Tom_itx: NSFW http://i.imgur.com/yISeNZ3.jpg
[12:22:15] <Tom_itx> that was quick. you must have those bookmarked
[12:22:35] <Jymmm> nah
[12:23:34] <ssi> gregcnc: decent machine?
[12:23:46] <CaptHindsight> why are the monsters feet so big?
[12:24:42] <Tom_itx> CaptHindsight, ever wear a foot brace?
[12:25:45] <gregcnc> I'm still working on mine. for the size they are nice. Stepper motors with 5um resolution on diameter. The made a 320 with servos and real controls.
[12:26:00] <Tom_itx> cpresser_, http://www.rivetwise.co.uk/rivets/rivet-nuts.asp
[12:26:22] <Jymmm> Tom_itx: Though this is MUCH sexier (semi-NSFW) http://i.imgur.com/6JT9quJ.jpg
[12:26:56] <JT-Shop> yuck time to clean the coolant tank on the CHNC
[12:27:03] <Jymmm> JT-Shop: Hey
[12:27:23] <Jymmm> JT-Shop: Were you serious or kidding when you said you make "fuel" from wood ?
[12:27:47] <Tom_itx> Jymmm, you can
[12:28:07] <Jymmm> Tom_itx: I realize it can be done, but dont know of anyone that has.
[12:28:25] <ssi> are we talking like wood gas, or something different?
[12:28:51] <Tom_itx> http://www.motherearthnews.com/green-transportation/wood-gas-truck-zmaz81mjzraw.aspx
[12:29:04] <Jymmm> ssi: Like powering a chainsaw from wood extracted fuel.
[12:29:17] <Tom_itx> that woudl be a bit bulky
[12:30:09] <JT-Shop> wasn't me
[12:30:49] * Tom_itx believes Jymmm has a honda: http://www.instructables.com/id/Convert-your-Honda-Accord-to-run-on-trash/
[12:31:20] <Tom_itx> wait... Ca plates... is that YOU!
[12:31:23] <Jymmm> Tom_itx: I sold it
[12:31:34] <jdh> /quit z
[12:31:44] <jdh> heh
[12:31:51] <ssi> jdh has a tell
[12:32:21] <Jymmm> JT-Shop: 2015-11-21.05:32:33 jthornton: yea, I know what wood gas is, I have plans for a wood gas generator somewhere lol
[12:32:36] <Jymmm> the logs never lie =)
[12:33:42] <malcom2073> That's totally furrywolf
[12:33:46] <malcom2073> speaking of which, where is he?
[12:33:56] <Tom_itx> someone told him to leave
[12:34:05] * Tom_itx looks at zeeshan|2
[12:34:07] <ssi> bah fw is too damn sensitive
[12:34:07] <malcom2073> Lol and he took them seriously?
[12:34:19] <malcom2073> Yeah you won't make it long on the internet if you leave when people tell you to
[12:34:22] <ssi> y'all goan have to try harder than that to run me out of here :
[12:34:23] <ssi> :)
[12:35:12] <Jymmm> Tom_itx: Bonus NSFW http://i.imgur.com/7Vfr0GT.gif

[12:35:40] <Jymmm> Tom_itx: it's animated =)
[12:38:57] <JT-Shop> like I said I have the plans somewhere
[12:40:15] <malcom2073> I kinda wanna try doing wood gas from grass clippings
[12:40:39] <malcom2073> Or pellatize them
[12:41:05] <Jymmm> malcom2073: pellet
[12:41:13] <malcom2073> yeah
[12:41:25] <Jymmm> lots on ebay, electric, diesel, etc
[12:41:45] <malcom2073> Why buy one when I can make one? :P
[12:42:00] <ssi> I could think of some reasons :)
[12:42:04] <malcom2073> Psh heh
[12:42:11] <malcom2073> I figured it'd be an interesting project to design and build a mill
[12:42:18] <Jymmm> malcom2073: Fine, make two, send me one and I'll be your beta bitch! I have SHIT LAODS of leave and pineneedles
[12:42:23] <malcom2073> Hah
[12:42:30] <malcom2073> I have a spare 17hp lawn motor I can use to run it
[12:42:44] <Jymmm> malcom2073: And no burn permit needed right now either.
[12:42:53] <malcom2073> I have a burn permit, it's $1 a year heh
[12:42:57] <malcom2073> here
[12:43:04] <malcom2073> but burning grass is smoky
[12:43:06] <ssi> I never burn with a permit
[12:43:16] <ssi> thanks folks, I'm here all week
[12:43:33] <malcom2073> That's unfortunate :P
[12:43:50] <malcom2073> Jymmm: Pay for my materials and I'll make two :-P
[12:44:38] <Jymmm> malcom2073: are you going for the tiny or 3/8" pellets?
[12:44:49] <malcom2073> 3/8, go big or go home
[12:45:09] <Jymmm> malcom2073: Let me know how much and I might consider it.
[12:45:11] <malcom2073> I figured use the gasoline motor to heat the thing too, and use some of the organic pellet glue
[12:45:23] <maxcnc> G eveninf from GERMANY
[12:45:32] <ssi> yay GERMANY!
[12:45:32] <Jymmm> malcom2073: IT's the compression that generates the heat iirc
[12:45:34] <maxcnc> g
[12:45:36] <malcom2073> Still working on the logistics, since there's little information on the process available, I need to do some testing
[12:46:01] <malcom2073> I had thought it might, was unsure
[12:46:19] <malcom2073> Gonna make some test rigs and compress some grass with a 50T press and see what happens heh
[12:46:39] <Tom_itx> press it harder and make diamonds
[12:48:38] <maxcnc> pcw_home: ?
[12:49:41] <pcw_home> yes?
[12:49:46] <maxcnc> ;-)
[12:50:03] <maxcnc> i did change today all mashine components as the com error
[12:50:04] <Jymmm> pcw_home: RUN! RUN FOR YOUR LIFE!!!!!
[12:50:28] <maxcnc> the mashine now is usabel ;-) BUT
[12:50:57] <maxcnc> the update for the 7i76 has the fault comerrors still eith no mashine brekdown
[12:51:13] <maxcnc> if ic change the 7i76 from a old mashine it has not
[12:51:42] <maxcnc> the old mashine insted with the new version 7i76 does provide the error imidet
[12:52:30] <maxcnc> is there a change to fet a version number on SW out of the device itself
[12:52:55] <maxcnc> to see if the SW is different it must i updated only one
[12:54:06] <Jymmm> Wood Gas Truck https://www.youtube.com/watch?v=aRbYiP0cJmg
[12:54:15] <pcw_home> Yes but the change only fixes a firmware bug (and that update was done about 2 years ago )
[12:54:28] <malcom2073> Yeah I've seen that video heh
[12:54:55] <maxcnc> the 3mashines are aboutt this old i dont know actuly as lothar buildet them
[12:55:52] <maxcnc> SO as yiou say its only a bug in firmware it has nothing to do on serial communication
[12:57:14] <maxcnc> i just dont understand why this fault ocures only on the updated one in different mashines that do not have that fault on non updated
[12:58:02] <pcw_home> main changes are that linuxcnc 2.7 has more complete error reporting.
[12:58:03] <pcw_home> As I said the 7I76 firmware update was a very limited bug fix
[12:58:05] <pcw_home> (for a bad but hard to trigger bug)
[12:58:06] <pcw_home> What is the actual sserial error? (this requires a dmesg log as the on-screen errors can lose the first error)
[13:03:50] <maxcnc> ok i missed that sorry i will check next year and report back
[13:03:58] <malcom2073> https://www.youtube.com/watch?v=Zygs9pb_zBw
[13:04:00] <malcom2073> That's scary
[13:08:01] <maxcnc> pcw_home: is there a prefered gronding point on the 7i76 i hooked it up to the DB25 connector
[13:08:19] <TAPit> I'm running a program (g code file) that should be 24 inches wide and long - it is 9 - LinuxCNC does move 10 inches when commanded to manually - any idea where I went wrong?
[13:08:34] <maxcnc> the 1284Cable is now inside a Double shilded tube with Ground on the outside and 24V on the inside
[13:09:03] <maxcnc> TAPit: SCALE in INI
[13:09:29] <maxcnc> TAPit: its in steps per unit MMorInch
[13:10:03] <TAPit> maxcnc - You are saying that the gcode must have a SCALE command at the 'beginning' ?
[13:10:06] <pcw_home> For a plasma machine, to avoid ground loops, I would not ground the 7I76 5V ground anywhere
[13:10:12] <swarfer> TAPit chekc that is has a G20 at the top, seems your machine might think it is metric
[13:11:08] <TAPit> maxcnc and sqarfer - I will relay to cnc operator. I have seen SCALE in the linuxcnc splash file.
[13:11:23] <swarfer> 20/9 = roughly 2.6 = roughly 2.5cm per inch? that is why I think the machine is in mm mode and the code is in inch, put G20 or G21 at the top of EVERY gcode file
[13:11:27] <pcw_home> (except at the PC)
[13:11:29] <pcw_home> that means no encoder or step/dir gnd pins connect to any local (to 7I76) gnd
[13:12:12] <maxcnc> pcw_home: no griounding on that side
[13:12:34] <pcw_home> the 24V I/O is isolated so not an issue, and normally the step/dir signals are isolated at the drives
[13:13:18] <pcw_home> also unless you need a fair amount of 5V from the encoder interface, its better to power the 7I76 from th e5I25/6I25
[13:13:33] <maxcnc> i dont think the problem is there as the same 7i76 runs fine on a mill but not on the plasma
[13:14:06] <maxcnc> you recomended that last time abnd i did it your way
[13:15:57] <pcw_home> sometimes a line filter on the PC helps
[13:15:58] <maxcnc> is this a part between the connectors
[13:16:06] <maxcnc> sry for my english
[13:16:41] <pcw_home> its a filer that goes in series with the PCs power connection
[13:16:47] <pcw_home> filter
[13:16:51] <CaptHindsight> http://www.designworldonline.com/how-do-you-really-use-3d-printing-systems/ "When asked what process was used for the initial prototype, the surprising answer was CNC machines, with more than two-thirds (67.61%) of the respondents turning here first."
[13:17:38] <maxcnc> pcw_home: i will get one
[13:18:24] <pcw_home> if the sserial error is multiple extra character errors, I have a 5I25 firmware change that
[13:18:26] <pcw_home> will improve noise rejection in the 5I25 receive UARTs
[13:19:38] <maxcnc> is this error 4
[13:23:02] <maxcnc> pcw_home: is the firmware available on the net
[13:25:32] <TAPit> maxcnc and swarfer - there is a G20 at the top of the file - when you say SCALE in ini - do you have a example entry?
[13:25:58] <TAPit> Or did you mean G50/G51 to set and cancel scaling?
[13:26:40] <maxcnc> NO does the mashine move wright in manuell movement ?
[13:26:58] <maxcnc> ARE you on IUnch or metric
[13:28:06] <swarfer> tapit said that it moves 10 inches if so commanded, so scaling must be correct, then we are left with inch/metric mode or the size of the Gcode itself, maybe th epostprocessor scaled it?
[13:28:36] <maxcnc> swarfer: right
[13:35:29] <JT-Shop> looks like the ball method to measure a taper is pretty good
[13:35:38] <maxcnc> TAPit: go to your mashine file folder open up the yourMashinename.ini file SCROLL down to [TRAJ] and read out the line LINEAR_UNITS =
[13:36:17] <gregcnc> JT-Shop, still working on the same one?
[13:37:37] <TAPit> maxcnc In TRAJ LINEAR_UNITS=inch
[13:38:02] <maxcnc> ok so is the Gcode also in inch i guess
[13:38:27] <TAPit> maxcnc yes we are using dxf2gcode and it is in inches
[13:38:28] <JT-Shop> just getting back to it and I cut a male part on the CHNC to test the fit
[13:39:03] <rob_h> Whos Idea was it to move machines this time of year!!
[13:39:09] <gregcnc> what did you decide was the actual taper?
[13:39:29] <maxcnc> TAPit: ok so in the INI file there is a line in [RS274NGC] RS274NGC_STARTUP_CODE =
[13:39:51] <maxcnc> Mine reads the RS274NGC_STARTUP_CODE = G17 G21 G54 G40 G49 G80 G90
[13:40:07] <maxcnc> Yours shoudt include the G20 instred of G21
[13:40:53] <swarfer> the G20 in the Gcode file shoudl still override that, surely?
[13:41:12] <maxcnc> swarfer: agree
[13:41:55] <maxcnc> TAPit: can you upload the gcode to pastebin ?
[13:44:16] <TAPit> maxcnc we havea RS274NGC entry but it says PARAMETER_FILE = linuxcnc.var and that is all
[13:44:51] <maxcnc> No problem
[13:46:05] <maxcnc> TAPit: can we get a look at the gcode to see if this is right
[13:47:50] <JT-Shop> 44°F and sun shining... time to go for a bike ride
[13:53:58] <TAPit> maxcnc yes I will upload to pastebin sorry for taking so long we were experimenting.
[13:55:56] <TAPit> maxcnc http://pastebin.com/iFA26qM6 it is a 24 inch by 24 inch L shape
[13:59:21] <Tom_itx> JT-Shop, snow.
[13:59:31] <JT-Shop> shut up
[13:59:41] <Tom_itx> just started
[13:59:50] <JT-Shop> keep it!
[13:59:55] <JT-Shop> sunny here
[14:00:17] <Tom_itx> it's moving due east
[14:00:30] <Tom_itx> http://www.intellicast.com/National/Radar/Current.aspx?animate=true&location=USKS0523
[14:00:36] <Tom_itx> bulls eye on your garage roof
[14:00:42] <maxcnc> TAPit: the gcode is clear
[14:01:14] <TAPit> maxcnc thanks and the machine moves 10 inches when told to manually move 10 inches. hmm and ugh.
[14:03:12] <maxcnc> TAPit: can you please put a G54 behind the G20
[14:03:26] <jdh> 81f here
[14:04:00] <maxcnc> TAPit: did you touch of at the P1 G54 coordinate system as we all expect
[14:08:11] <_methods> wtf is g64
[14:08:39] <maxcnc> _methods: its a speed up for litel gcode pathes
[14:08:51] <_methods> wtf is litel
[14:09:04] <maxcnc> overtakes some small steps and rounds corners by the given P
[14:09:05] <jdh> french spelling of little
[14:09:24] <maxcnc> _methods: G64 P0.2
[14:09:25] <_methods> oh is the g64 the trajectory planning they added or something
[14:10:03] <maxcnc> no as it is since 2.3 in use
[14:10:07] <_methods> oh lol
[14:11:28] <maxcnc> its realy good on foam or loose material
[14:11:40] <maxcnc> also on 3D sculps its perfect
[14:12:21] <TAPit> maxcnc we just got to the point of running a gcode file this morning - it worked perfectly - had a following error - I slowed machine in .ini - did other work - at some point we were thinking 'that is a bit small' and now here we are. I will try G54 after G20 now. Yes we did 'touch off' all three axis.
[14:13:29] <TAPit> maxcnc G54 did not change anything - a side note - after touching off - the shape is no longer 'on the table' but now moves so far to the left that it leaves the table.
[14:13:57] <_methods> yeah you must have touched off wrong
[14:14:11] <_methods> home your machine
[14:14:15] <_methods> then touch off on the part
[14:14:20] <_methods> work coordinate offset
[14:14:30] <_methods> seems like a lot of people like to home the machine on the part
[14:15:10] <maxcnc> _methods: Mach 3 users for instant as they came in shop first time linuxcnmc
[14:16:05] <_methods> well i think it's an easy concept to get confused when you're first starting
[14:16:12] <_methods> homing vs work offsets
[14:16:36] <maxcnc> ok im of for this year HAVE a good Xmas party and sray dry on Newyears eve BYE from Germany
[14:17:43] <TAPit> In the overall configuration - which parameter sets the size of the work area? MIN_LIMIT and MAX_LIMIT?
[14:18:05] <_methods> they both do
[14:18:16] <_methods> of min is 0 and max is 18
[14:18:16] <TAPit> and they are in inches right?
[14:18:20] <_methods> your work area is 18
[14:18:43] <_methods> or if your min was -18 and max was 18
[14:18:48] <_methods> you'd be at 36
[14:19:10] <TAPit> we have min set to -5 and set to 72 which is 1/2 of our actual work area (one table)
[14:19:19] <_methods> it just depends on how your machine is physically set up
[15:14:39] <CaptHindsight> https://www.kickstarter.com/projects/nx1/nx1-the-first-fast-3d-printer fast SLA printer people don't really seem to want. Italian? No maker* or cutesy in name? Can't tell where the table ends and printer begins?
[15:15:06] <CaptHindsight> lack of any wood grain?

[15:20:18] <_methods> i was reading this morning that those kickstarter morons finally figured out the laser razor was a LIE
[15:20:24] <_methods> ermahgerd
[15:20:41] <CaptHindsight> was it a complete scam?
[15:20:45] <_methods> oh yeah
[15:21:00] <_methods> how many millions did people sign up to give away for that too
[15:21:10] <_methods> kickstarter is the new ponzi
[15:21:21] <_methods> or as sold on tv

[15:22:18] <_methods> heheh
[15:22:19] <enleth> pcw_home: hi, do you think it would be OK if I arranged for a courier to pick up stuff at Mesa after placing an order without shipping included? It appears that a collection request placed at my local branch of an international shipping company may be significantly cheaper than paying for shipping the usual way.
[15:22:20] <_methods> yep
[15:22:36] <CaptHindsight> they jumped from poopstarter to indepoopoo
[15:23:14] <enleth> CaptHindsight: kickstarter was OK at the beginning, then it went to shit at some point
[15:23:25] <enleth> but it's still better than everything else I guess?
[15:23:41] <gregcnc> some guys still use it after they are established?
[15:23:49] <CaptHindsight> how about a combo xray face scanner and razor?
[15:23:56] <_methods> do it
[15:24:01] <Tom_itx> it's done kick started. now it's a scam
[15:24:03] <_methods> airbag rzor
[15:24:18] <gregcnc> https://www.kickstarter.com/projects/tactical/ti-mqr-titanium-magnetic-quick-release-edc-keychai?ref=project_link
[15:24:26] <CaptHindsight> or a belt sander exfoliator
[15:24:27] <_methods> place your face against airbag and inflate rapidly to remove localized facial hair
[15:24:52] <Tom_itx> or for a _new_ look
[15:24:57] <enleth> https://www.kickstarter.com/projects/1623255426/fps1000-the-low-cost-high-frame-rate-camera - this is one of the kickstarter projects I'm following. I did not know about it when it was in the fundraising phase but I would contribute if I did.
[15:25:05] <CaptHindsight> CO2 nozzle and then snap the hair off
[15:25:14] <CaptHindsight> may cause slight skin irritation
[15:25:25] <gregcnc> I want an fps1000 too, it sounds like they've shipped some
[15:25:32] <enleth> The guy seems to be legit and if his camera works, it will be crazy awesome
[15:26:03] <enleth> high-FPS machining videos are both cool and informative
[15:26:09] <CaptHindsight> you either need a fast enough sensor or multiple sensors
[15:26:28] <SpeedEvil> Or a line camera
[15:26:32] <SpeedEvil> (for some things)
[15:26:44] <CaptHindsight> I built some super fast cameras in the past for strip mining
[15:27:00] <gregcnc> tactical keychain guy doesn't need crowdfunding, I'm not sure why he continues to give them what 12%?
[15:27:03] <CaptHindsight> they would examine the explosions and optimize
[15:27:30] <enleth> CaptHindsight: I think he's got some kind of mostly off-the-shelf sensor and put a lot of work into making all the support stuff around it on the cheap
[15:27:37] <CaptHindsight> the greatest expense in strip mining was the cost of the explosives
[15:28:41] <enleth> If it ships and someone confirms that it meets the advertised specs, I'm definitely buying one
[15:28:56] <SpeedEvil> I want a strategic keychain.
[15:30:15] <gregcnc> I don't get the product either, but he's making money all in his garage.
[15:31:39] <enleth> gregcnc: well at least he's selling something he actually made, and it exists, and seemingly is exactly what's advertised
[15:31:45] <_methods> wtf is a strategic keychain
[15:32:12] <enleth> _methods: it's for when "tactical" no longer sounds cool because you can get anything tactical
[15:32:20] <lair82> pcw_home you around?
[15:32:39] <_methods> i'm googlin it and all i'm getting is password keychains lol
[15:32:44] <_methods> and marvel shield keychains
[15:33:25] <anomynous> how about cryptonite keychains?
[15:34:08] <gregcnc> tacticalkeychains.com looks like he stopped the site. try https://www.instagram.com/tacticalkeychains/
[15:34:48] <anomynous> what are you looking for
[15:35:08] <_methods> https://www.kickstarter.com/projects/tactical/ti-mqr-titanium-magnetic-quick-release-edc-keychai?ref=project_link
[15:35:32] <_methods> its just a keychain?
[15:35:45] <_methods> hahahahah
[15:35:49] <_methods> a magnetic keychain
[15:35:52] <gregcnc> a magnet holds the halves together for quick release
[15:36:08] <_methods> $70k for a magnetic keycahin
[15:36:20] <_methods> gotta love kickstarter
[15:38:58] <DaViruz> looks like a perfect way to lose your keys
[15:39:18] <_methods> and wipe any usb drives in the area
[15:39:36] <anomynous> does magnet wipe them?
[15:39:39] <_methods> nah
[15:39:40] <gregcnc> no
[15:40:00] <_methods> but floppy disks
[15:40:02] <_methods> look out
[15:40:14] <anomynous> im not using floppydisks anymore
[15:40:22] <_methods> you're missin out
[15:40:27] <anomynous> :(
[15:40:47] <anomynous> hmm... is floppy the hard floppy of flexy floppy?
[15:41:33] <_methods> i think it could be all of them
[15:42:05] <anomynous> having a rar or zip packaged over many floppies and having an error in one of them :(
[15:45:28] <Tom_itx> single sided 5.25" FTW
[15:45:49] <_methods> hehe notched with a paper punch
[15:45:56] <Tom_itx> yup
[15:46:09] <CaptHindsight> How do magnets work?
[15:46:17] <_methods> no one knows
[15:46:24] <Tom_itx> perpetually
[15:46:26] <_methods> is mystery
[15:46:37] <CaptHindsight> si it's like asprin or oprah?
[15:46:43] <_methods> both
[15:46:46] <_methods> in one magical cup
[15:46:55] <_methods> called the magnet
[15:48:25] <CaptHindsight> is this faith based or does it work via contributions or both?
[15:48:30] <Tom_itx> we'd be screwed without em
[15:48:51] <Tom_itx> i've contributed plenty to magnets
[15:48:57] <gregcnc> there was a later article on cnet about the laser razor seemed like the tech is real, but it only cut one hair at a time right now and the fiber is impractically fragile.
[15:49:04] <CaptHindsight> "Is it safe from my child to swallow the keychain?"
[15:49:06] <DaViruz> i'm using floppy discs again. the control on my emco mill uses 3.5" DD-discs :)
[15:49:20] <CaptHindsight> from/for
[15:49:20] <Tom_itx> they're physical therapy
[15:49:30] <gregcnc> F1 CNC?
[15:49:44] <DaViruz> vmc-100
[15:50:00] <Tom_itx> https://en.wikipedia.org/wiki/Magnet_therapy
[15:50:12] <DaViruz> silly little machine, but i got it for a pretty decent price
[15:50:50] <gregcnc> I have a pcmill 125, virtually the same
[15:50:56] <DaViruz> picked up a emco lathe from the same place
[15:51:09] <DaViruz> that one uses mini cassette tapes. that's even more troublesome then floppys
[15:52:28] <gregcnc> 20-30 years old
[15:52:36] <CaptHindsight> so it's a combination key chain, floppy and magnetic tape eraser, crt color mangler, refrigerator note holder
[15:53:03] <Tom_itx> you should get alot for one of those
[15:53:51] <FinboySlick> Sort of reminds me of that AvE quote: "Why would you use a microcontroller when all you need is a 555, two diodes and a time machine to go back to 1979?"
[15:54:01] <DaViruz> :D
[15:54:57] <CaptHindsight> 555 in DIP package might require a time mashine
[15:54:59] <DaViruz> i picked up a mini cassette to make a backup of the machine data. rs232 is probably a bit more convenient for program transfer
[15:55:10] <_methods> yeah i guess i kinda sold it short......it has so many uses lol
[15:55:13] <_methods> magnetic thereap
[15:55:17] <_methods> therapy even
[15:55:27] <CaptHindsight> dream catcher
[15:56:01] <CaptHindsight> it can hold bags closed without making a hole
[15:57:05] <CaptHindsight> keep fresh socks, gloves, clothing on the side of your VMC with no drilling or gluing
[15:58:15] <gregcnc> fresh pant liners for when the Estop is really needed
[15:58:27] <CaptHindsight> I can already see the infomercial
[15:59:59] <anomynous> how deep can indexable drill drill into steel dry without melting?
[16:00:07] <anomynous> or clogging
[16:00:37] <DaViruz> i was contemplating the most convenient way to mill a hex on the end of a rod
[16:00:43] <DaViruz> when a friend showed me these:
[16:00:46] <DaViruz> http://www.arceurotrade.co.uk/Catalogue/Collets/ER-Collet-Fixtures#Stevensons-ER40-Collet-Blocks
[16:00:52] <DaViruz> quite nifty
[16:01:08] <DaViruz> possibly quite well known though i guess
[16:01:18] <gregcnc> In 5C flavor yes
[16:01:37] <CaptHindsight> isn't there a womens razor that uses light on TV?
[16:01:43] <gregcnc> ER blocks are specific to that source.
[16:01:52] <_methods> heh never seen ER ones
[16:01:55] <_methods> only 5c
[16:02:01] <DaViruz> oh
[16:02:23] <DaViruz> i have nothing 5C, but a bit of ER stuff
[16:03:03] <gregcnc> capt, those are hot wire i think
[16:03:49] <CaptHindsight> https://www.silkn.com/flash-and-go/ here it is
[16:04:43] <gregcnc> that's probably new if it's for home use
[16:04:55] <gregcnc> profesional machines have been around for a long time
[16:06:02] <gregcnc> industry recycles just sent me endmills and a bag of candy
[16:06:12] <CaptHindsight> https://youtu.be/zW7uZU7WXXM?t=2m44s Flash & Go Update #4 NSFB (not safe for bigots)
[16:08:44] <FinboySlick> CaptHindsight: https://www.youtube.com/watch?v=AYbP-fkiJ0o is a bit manlier.
[16:10:41] <cradek> I've read that nothing but electrolysis really works well at all, especially home stuff
[16:11:50] <FinboySlick> "On a scale of one to America, how free are you tonight?"
[16:12:19] <CaptHindsight> UV would have to be low enough to fend off an lawsuits over cancer
[16:12:25] <CaptHindsight> an/any
[16:13:56] <CaptHindsight> then again that what many of these outfits do is sell a buttload of something then go "bankrupt" before the suits
[16:14:32] <CaptHindsight> but the 6-7 figure salaries have all been paid
[16:43:31] <Deejay> gn8
[17:17:12] <Jymmm> How to scare the fuck out of Jymmm...
[17:18:18] <Jymmm> Have a pyro experiment started inside, go out on the back porch for a few minutes, watch the lil smoking coning out of the chimney, then all of a sudden see smoke coming out from under the porch!
[17:19:27] <Jymmm> Sidenote: GF doing laundry which VENTS to under the porch (aka steam, not smoke =)
[17:47:53] <Tom_itx> false alarm
[18:07:12] <SpeedEvil> http://imgur.com/gallery/OlpI8cf This is not CNC.
[18:14:03] <Tom_itx> they compete to see how thin they can cut it
[18:16:19] <JT-Shop-> touch probe is here
[18:16:26] <Tom_itx> cool
[18:16:31] <Tom_itx> it can snow now.
[18:16:38] <Tom_itx> you must stay in and play
[18:17:07] <JT-Shop-> looks nice
[18:17:14] <JT-Shop-> a lot smaller that I thought
[18:17:45] <Tom_itx> what's the diameter?
[18:18:28] <PetefromTn_> What touch probe did you get?
[18:18:42] <JT-Shop-> about 1.148"
[18:19:03] <PetefromTn_> wow that is tiny
[18:19:12] <Tom_itx> sounds about right
[18:19:15] <JT-Shop-> seems well made
[18:19:27] <Tom_itx> i made a smaller one for my sherline and a couple larger ones
[18:19:39] <JT-Shop-> lol facebook wants me to be a friend with Pete
[18:19:50] <PetefromTn_> ?
[18:19:52] <Tom_itx> not sure i'd friend him...
[18:19:57] <Tom_itx> he's quite a character
[18:20:02] <PetefromTn_> you mean PCW?
[18:20:03] <JT-Shop-> not sure how they guess that
[18:20:21] <JT-Shop-> no, you
[18:20:40] <PetefromTn_> I didn't friend request you but I just never thought of it ;)
[18:20:56] <JT-Shop-> it was a suggested friend
[18:21:03] <PetefromTn_> besides you are right....I am an azzhole so why would you want to LOL
[18:21:15] <JT-Shop-> I'm like how did they know I know you
[18:21:33] <JT-Shop-> I don't get on there much
[18:21:37] <PetefromTn_> that is a good question
[18:21:47] <Tom_itx> i stay off those types of social media
[18:21:55] <PetefromTn_> I have no idea how they get suggestions
[18:21:58] <JT-Shop-> I did some steel fencing for a guy and they suggested him too
[18:22:05] <PetefromTn_> honestly I quite enjoy facebook
[18:22:19] <JT-Shop-> anyway time to put on the chef hat
[18:22:27] <PetefromTn_> there are lots of groups on there that I am in for different things
[18:22:41] <JT-Shop> we need to play with probing tomorrow
[18:22:56] <PetefromTn_> and none of them have anything to do with furry costumes :D
[18:24:42] <PetefromTn_> so is nobody gonna tell me what probe he got?
[18:24:52] <Tom_itx> i can't remember
[18:24:57] <Tom_itx> it's in your logs
[18:25:17] <PetefromTn_> OK dinner time...
[18:47:57] <FloppyDisk> @petefromTN_ I think JT got this probe: http://deepgroove1.com/stainlessprobe/stainlessprobe.htm
[18:48:24] <FloppyDisk> I pulled it off the emc mailing list. Although, there were a lot of probes suggested and I think that was it, JT to confirm.
[18:56:34] <skunkworks> if you keep an eye on ebay you can get some renishaw knockoffs or even a renishaw for less than that..
[18:57:28] <skunkworks> like http://electronicsam.com/images/KandT/probe/PROBE2.JPG
[19:11:21] <PetefromTn_> Okay back from dinner
[19:11:31] <PetefromTn_> FloppyDisk thanks for the link.
[19:11:37] <CaptHindsight> what did we have?
[19:11:37] <PetefromTn_> that looks decent actually
[19:12:12] <PetefromTn_> Oh Dacia made some Chicken Parmesan and rotini noodles
[19:12:45] <CaptHindsight> here's the deal of the week http://www.ebay.com/itm/Matsuura-760-V-2-cnc-mill-plus-free-cnc-knee-mill-Great-Deal-/262179867379
[19:12:48] <PetefromTn_> skunkworks that looks nice man
[19:13:00] <CaptHindsight> $4500 or best for 2 mills!
[19:13:07] <CaptHindsight> both cnc
[19:13:12] <CaptHindsight> and working
[19:13:15] <PetefromTn_> yup pretty nice
[19:13:31] <PetefromTn_> Anyone getting anything cool for Christmas?
[19:13:54] <CaptHindsight> is anyone wants the knee mill I have room for the 760V :p
[19:15:38] <FloppyDisk> @PetefromTn_ You're welcome. Like I said, should confirm w/ JT, but he can simply yeah or neah...
[19:15:57] <CaptHindsight> ohh another one http://www.ebay.com/itm/MATSUURA-14C-760V-Tsudakoma-12-1-2-Hor-Vert-Rotary-Table-RNCV-300R-/301798798319 for $2500
[19:16:03] <CaptHindsight> in Florida
[19:16:08] <FloppyDisk> I got some digikey parts to make an encoder:-) otherwise, not so much...
[19:16:37] <CaptHindsight> yikes, but it looks like it was left outside :(
[19:16:52] <PetefromTn_> yeah thats a deal breaker I think
[19:17:04] <PetefromTn_> nobody getting anything cool for Christmas?
[19:17:05] <CaptHindsight> http://i.ebayimg.com/images/g/oV8AAOSweuxWR1dG/s-l500.jpg
[19:17:29] <PetefromTn_> skunkworks what kind of probe is that you linked?
[19:19:14] <PetefromTn_> http://i.ebayimg.com/00/s/MTAxNFgxMjE2/z/a7cAAOSw2s1UwVvX/$_1.JPG We're getting a couple of these for Christmas!! I CAN'T WAIT!!

[19:19:52] <g_mouer> hi guys, have not been here in quite a while, does Andy Pugh still hang out? I'm pulling my hair out trying to bench test a redcap servo with BLDC.
[19:20:15] <CaptHindsight> stable enough to stand in?
[19:20:32] <PetefromTn_> yeah apparently ;)
[19:20:43] <PetefromTn_> we took a test ride this past weekend on them
[19:20:50] <PetefromTn_> there is a dealer in Chattanooga
[19:20:51] <CaptHindsight> g_mouer: he's around often
[19:21:00] <PetefromTn_> we took a ride down and they let us test some
[19:21:02] <CaptHindsight> must have called it an early night tonight
[19:21:06] <g_mouer> thanks capt !
[19:21:24] <g_mouer> heck of a lot easier to troubleshoot a prob here than the forum
[19:21:35] <PetefromTn_> https://www.youtube.com/watch?v=QHta4ASFC60
[19:21:39] <CaptHindsight> almost 1am his time
[19:22:15] <PetefromTn_> http://cdn3.bigcommerce.com/s-2kv17xia/products/151/images/494/skipjack90__95875.1436492523.1280.1280.jpg?c=2 Getting two of these for the kids
[19:22:31] <g_mouer> yea, my shop computer pwr supply went belly up, just got it online a few mins ago again
[19:23:38] <CaptHindsight> we have a few acre retention pond next door, been tempted to get a paddle boat
[19:24:07] <PetefromTn_> yeah man there are TONS of lakes, rivers, streams around us here.
[19:24:25] <PetefromTn_> I can't wait to start fishing from these and exploring our area.
[19:24:40] <PetefromTn_> They are gonna be also great if we ever sell our house and move back to Florida
[19:24:53] <PetefromTn_> perfect for the indian river/intercoastal
[19:25:01] <g_mouer> talking about deals, a good friend picked up 2 Kryle VMC's for $170 on a sealed bid sale from a school. modern machines, fanuc controls that lost parameters, company isn't around anymore, linuxcnc retrofits to be done once I blaze the redcap servo part of the retro for him
[19:25:03] <PetefromTn_> and lots of these guys take them out on the ocean to fish
[19:25:21] <g_mouer> that $170 included free delivery and tooling !
[19:25:40] <PetefromTn_> WOW
[19:26:07] <g_mouer> yea, hellva deal !
[19:26:11] <malcom2073> Nice!
[19:26:24] <malcom2073> Sometimes you luck into good deals
[19:26:39] <g_mouer> no, he lucks into them, I only hear about them LOL
[19:26:58] <PetefromTn_> tell him you will retro one for him for the other one ;)
[19:27:05] <g_mouer> 800 inch a minute class machines
[19:27:16] <g_mouer> ha ! I tried that Pete !
[19:27:27] <PetefromTn_> that is about like my Cincinatti
[19:27:40] <PetefromTn_> mine can do 730 or so but I am scared to ;)
[19:28:21] <g_mouer> the redcap servos thicken the plot a bit I volunteered to sort that part of the retro out
[19:28:41] <PetefromTn_> talk to PCW I think he had some info on that.
[19:29:04] <g_mouer> I know, some great minds around here
[19:29:12] <malcom2073> lol
[19:29:20] <malcom2073> Haha
[19:29:26] <malcom2073> I'm lucky if my machine does 30ipm :P
[19:29:35] <malcom2073> I'll bet the stock servos could go really fast though
[19:29:45] <PetefromTn_> the only thing great about my mind is it's ability to wander uncontrollably at any moment
[19:29:56] <malcom2073> Our matsuura 500 at work is scary fast
[19:30:14] <g_mouer> I picked up a 20 inch toolroom type cnc lathe this summer for $1000 was supposed to be dead, had it up and running in about a half hour, bad crt connection dynapath 40 control
[19:30:31] <PetefromTn_> jeez
[19:30:44] <g_mouer> one owner, from a speedshop
[19:30:48] <PetefromTn_> My CNC lathe I got for $500 but it needed the entire control and a good cleaning
[19:30:56] <PetefromTn_> Still working on it here.
[19:31:07] <malcom2073> Nice, I got my 12x36 for $250 at auction, that's the best deal I've ever gotten
[19:31:13] <malcom2073> manual
[19:31:15] <malcom2073> not cnc
[19:31:18] <g_mouer> bison chucks look brand new
[19:31:32] <PetefromTn_> I once bought a manual 16x60 asian lathe for $300
[19:31:34] <enleth> malcom2073: wow, that sounds like a great deal
[19:31:43] <malcom2073> enleth: It was, it was a tiny auction, poorly advertized
[19:31:46] <PetefromTn_> I need a chuck for this beast
[19:31:55] <malcom2073> It's a late 80's grizzly/central precision
[19:32:19] <g_mouer> just getting back into cnc and the shop after moving to SC from MY state a couple years back
[19:32:27] <malcom2073> centra/machine rather
[19:32:46] <g_mouer> built a 32x50 pole barn for a toybox, just need the floor poured to complete now
[19:32:55] <bobo__> g_mouer as Pete noted PCW may help, ssi is/was working on a servo driver supply for yellow or red caps
[19:33:05] <malcom2073> I need to get some quotes to get my polebarn poured
[19:33:42] <enleth> I'm looking into buying a lathe soon and all I can get is old east bloc crap or chinks, I can only dream of a vintage Sherline or something
[19:33:46] <g_mouer> I am extremely lucky, part retired and the place I work for does a lot of that kind of work, so I will get it done at cost.
[19:33:46] <PetefromTn_> well I got some machining to do here so I can get some cash for Christmas to pay for these damn boats ;)
[19:34:30] <g_mouer> toys come first Pete, you got it right
[19:34:34] <enleth> To add insult to injury, I can't even easily get a proper Sieg lathe
[19:34:53] <enleth> Only Sieg knockoffs
[19:35:26] <PetefromTn_> g_mouer I hear ya man. Honestly MOST of the time work comes first around here as does parts/tooling for work but I have been wanting to get some kayaks for awhile now.
[19:35:58] <PetefromTn_> We WERE going to get a pair of nice canoes but actually these kickass fishing kayaks are cheaper LOL believe it or not.
[19:37:00] <g_mouer> I followed your RF45 retro, got one myself, about half done, belt drive done, Z moving, brushless servos
[19:37:13] <PetefromTn_> Oh yeah COOL
[19:37:27] <PetefromTn_> I actually liked that little mill it was pretty decent
[19:37:41] <PetefromTn_> I redid the whole damn machine
[19:37:47] <PetefromTn_> took almost a year LOL
[19:38:03] <g_mouer> I got it before I built the barn this summer, it would fit well into my 12x24 shed
[19:38:55] <PetefromTn_> If i found a smoking deal on a used one I would get it, probably keep it manual as a second op machine for the VMC but it makes a good retrofit machine IMHO
[19:39:15] <g_mouer> then.... a bridgeport boss fell on my lap this summer, part done retro with all parts, prev owner died, wife wanted garage back, offered it to me for $300 with all the retro parts couldn't pass that up
[19:39:37] <PetefromTn_> jeez man you are a lucky one
[19:39:51] <PetefromTn_> I bought my VMC for 1300 with a bad Z axis
[19:39:57] <g_mouer> yea, this summer was a good one for finding machines
[19:40:01] <PetefromTn_> thats probably the best deal I ever got
[19:40:27] <g_mouer> local guy has a haas VF2 for $2000 OBO about a month ago, had a keyboard problem
[19:40:43] <PetefromTn_> DAMN that is a smoking deal
[19:40:44] <bobo__> so Pete how soon are taking a trip down the New River in that there boat thing?
[19:40:50] <g_mouer> I gotta stay off that damn craigslist
[19:41:00] <PetefromTn_> dunno where is the new river?
[19:41:44] <g_mouer> what part of TN you in Pete? east or west?
[19:41:48] <PetefromTn_> east
[19:42:02] <g_mouer> I'm in Anderson SC, not far away
[19:42:03] <PetefromTn_> until I can sell my damn house and then I will be PetefromFL
[19:42:15] <PetefromTn_> oh yeah
[19:42:18] <bobo__> west virginia
[19:42:27] <PetefromTn_> I am just south of Knoxvegas
[19:43:00] <PetefromTn_> we are about three miles from Chilhowee lake
[19:43:15] <g_mouer> movingis a PITA I sold off my machines, just getting more now. Kept all the tooling and such though
[19:43:15] <PetefromTn_> and not more than 5 from the Tennessee River/little river areas
[19:43:34] <g_mouer> almost neighbors
[19:43:45] <PetefromTn_> really you are that close?
[19:44:16] <g_mouer> gimme a city pete, I will google map and see how far
[19:44:49] <PetefromTn_> just looked at the map...you are close huh
[19:45:04] <PetefromTn_> I visited a guy in SC that helped me with my RF45 CNC build
[19:46:07] <PetefromTn_> Cherokee is like 45 minutes from my house....we went and saw Alice in Chains there recently
[19:48:11] <PetefromTn_> well back to work
[19:48:24] <g_mouer> nice chatting Pete
[19:49:01] <PetefromTn_> yeah man
[19:53:36] <bobo__> PetefromTn: New River Gorge in West Virgina
[19:58:05] <toastydeath> fuck my life, I need to figure out some way to connect pins to test leads
[19:58:13] <toastydeath> the pins are a non-standard size and are recessed
[19:58:16] <toastydeath> they carry power
[19:58:18] <toastydeath> thoughts?
[19:59:51] <tiwake> each time I do a little welding job I'm reminded why I don't like welding
[19:59:52] <tiwake> lol
[20:00:59] * tiwake goes back to yelling at the welding machine
[20:26:47] <CaptHindsight> tiwake: mine are deaf
[20:27:47] <tiwake> mine is too
[20:28:12] <tiwake> CaptHindsight: most of my yelling is translated to fierce glaring
[20:28:13] <tiwake> lol
[20:29:26] <CaptHindsight> I need an application that looks at my parts and then creates the toolpath for the mating parts
[20:29:38] <CaptHindsight> all one of a kind
[20:29:52] <malcom2073> *screaming internally in spanish*
[20:30:05] <toastydeath> CaptHindsight, can't subtract from a block?
[20:30:50] <CaptHindsight> toastydeath: it should do it when I'm asleep and have the parts when I come back in morning
[20:30:56] <toastydeath> oh
[20:31:13] <CaptHindsight> guess I need elves
[20:31:20] <toastydeath> i mean i have done that before, if you trust your machine
[20:31:21] <gregcnc> isn't that called an employee, well a good one
[20:31:34] <toastydeath> but did it in solidworks
[20:33:08] <toastydeath> have a block, align part to a datum, subtract
[20:33:11] <toastydeath> generate toolpath
[20:39:16] <CaptHindsight> toastydeath: yeah, if you have the data for the original part
[20:40:10] <CaptHindsight> 3d scan --> NX --> NX-CAM ---> linuxcnc
[20:40:32] <toastydeath> oh, tru
[20:40:34] <CaptHindsight> ^^ these steps while I'm sleeping :)
[20:42:14] <CaptHindsight> the most I usually get are simple catalog drawings with mounting holes
[20:42:22] <CaptHindsight> in some shorthand
[21:00:34] <skunkworks> PetefromTn_: big
[21:06:33] <Erant> Woohoo. Endmills! The rougher looks like a mean sob
[21:08:28] <CaptHindsight> Erant: where did you end up ordering from?
[21:16:10] <SpeedEvil> http://imgur.com/gallery/MCGxmcL on buisness cards
[21:21:01] <Erant> CaptHindsight: SunCoast Precision Tools
[21:21:38] <CaptHindsight> doesn't sound very Chinese :)
[21:22:35] <Erant> They're not. They're US made.
[21:23:19] <Erant> The rougher's from Melin, and I got two 3/8" HSS mills which are made by...
[21:23:25] <Erant> Huh, says Korea on the box.
[21:23:38] <Erant> The Melin one is made in the US though
[21:24:40] <Erant> Very excited to try that one out.
[21:25:39] <gregcnc> Erant what kind of machine are you runnign them in again?
[21:36:12] <trentster> hey all - water cooled spindle additives - opinions please?
[21:36:25] <Erant> gregcnc: Micro mill
[21:36:32] <trentster> Also is tap water fine or do I really 100% need distilled water?
[21:36:53] <trentster> will anti freeze damage a spindle? if no? what ration do I add to water volume?
[21:43:08] <irontree9> anyone know a good place for bits. he ones I have suck
[21:46:43] <Tom_itx> bits of what?
[21:48:01] <irontree9> cutting bits
[21:48:48] <Erant> gregcnc: I got the numbers off http://www.endmill.com/pages/training/Speed%20and%20Feed%20-%20Roughers.pdf which I'll just use, see what happens.
[21:49:12] <Erant> irontree9: Mills? Drills? Boring bars? Lathe tools? Little bit more specific.
[21:49:17] <gregcnc> How mcuh power do you have?
[21:49:24] <irontree9> Milling
[21:49:28] <Erant> gregcnc: Not a lot. 1/3HP :/
[21:49:45] <irontree9> tiny routing type. 1/8" or 1mm
[21:49:55] <gregcnc> trenster, I think it's just antifreeze, buy some borate and silicate free type
[21:50:11] <Erant> irontree9: What kind of material? Wood, plastic, aluminum?
[21:50:20] <irontree9> atm wood
[21:50:56] <Tom_itx> you want good ones?
[21:51:06] <Erant> Guessing that's like a single flute...
[21:51:43] <Tom_itx> http://www.lakeshorecarbide.com/ has good stuff
[21:51:53] <Tom_itx> travers.com has good stuff
[21:52:01] <irontree9> Just want one that can plunge, cut sideways and life the material out instead of packing it down
[21:52:03] * irontree9 clicks
[21:52:48] <gregcnc> for small stuff like that the kyocera stuff. i get it from this guy http://stores.ebay.com/CARBIDE-PLUS?
[21:53:28] <gregcnc> Erant, you'll want to check cutting power and torque http://zero-divide.net/index.php?page=fswizard
[21:53:47] <Erant> gregcnc: Probably going to start with 0.375 DOC, 0.05 WOC, @ 2500 RPM and 18IPM
[21:53:54] <Erant> Yeah, I use that one a lot.
[21:54:25] <Tom_itx> you can put that on your phone too
[21:59:31] <irontree9> http://www.lakeshorecarbide.com/132carbideballendmill2flutetialncoated.aspx
[21:59:49] <gregcnc> Seems reasonable, have you been using regular cutters? I've only used roughers in my smallish manual machine last one i tested was Ø1/2", 1" DOC, .08W, maybe 1600RPM. as fast as could turn the handles made a nice shower of fine chips
[21:59:51] <irontree9> That should be good for engraving about 4mm deep into wood, yes?
[22:00:48] <Contract_Pilot> Sup All
[22:01:01] <ReadError> anyone ever seen some reliable methods for figuring out motor torque requirements?
[22:01:08] <ReadError> in the past ive just freeballed it
[22:01:31] <gregcnc> torque for what?
[22:01:32] <ReadError> but want to get the lightest suitable motor
[22:01:51] <ReadError> gregcnc: x and y axis drives
[22:01:56] <Contract_Pilot> Gun show table all set up.
[22:01:57] <ReadError> on a PNP
[22:02:30] <gregcnc> PNP?
[22:02:45] <ReadError> pick-and-place
[22:06:25] <toastydeath> oh my god my oscilloscope works
[22:06:58] <gregcnc> if you want to optimize it, need to look at mass and acceleration to get torque, there isn't much force required other than friction I would think.
[22:08:10] <gregcnc> http://machinedesign.com/motorsdrives/how-pick-motors-linear-motion
[22:08:23] <Erant> gregcnc: So this is what's confusing me a little. Melin says 0.00225" per tooth. FSWizard seems to go 0.0045" per tooth...
[22:08:34] <Erant> And I set it to HSCobalt.
[22:09:41] <gregcnc> That .002 you mention doesn't match what I found on the melin site. .0045 isn't out of line for a 3/8" cutter in aluminum
[22:10:09] <Erant> Got it from here: http://www.endmill.com/pages/training/Speed%20and%20Feed%20-%20Roughers.pdf
[22:12:03] <gregcnc> the page I sent posted the other day had different numbers. you can run slower, it's ok, but faster won't hurt the tool and it will last longer overall.
[22:12:49] <Erant> I'll give a heavier chipload a shot, see what the machine does.
[22:13:44] <Erant> 1500RPM @ ~18IPM or so.
[22:14:15] <toastydeath> how rigid is your machine - 18ipm can be a bit much, if it complains a lot keep bumping the rpm down
[22:14:21] <toastydeath> to drag the feed back too
[22:14:51] <toastydeath> (i agree w/ gregcnc about the chip load, just that the actual linear feed rate might give you problems)
[22:15:11] <Erant> I was able to do about 20IPM with a light-ish cut with a sharp endmill.
[22:15:31] <Erant> 0.05" DOC, slotting the 3/8"
[22:15:45] <gregcnc> with small machines you just have to see what works.
[22:15:53] <Erant> Which is what I'll do
[22:23:52] <Erant> I'm getting the machine tuned a little more to where I want it to be, slowly but surely...
[22:34:53] <irontree9> Almost have mine tunned...... blood thirsty monster.
