[02:38:50] <Deejay> moin
[06:42:03] <jthornton> dang noisy fan on the video card
[07:16:14] <Tom_itx> did it wake you up?
[07:21:49] <archivist> it woke me this side of the pond!
[07:56:08] <mrsun_> hmm would you say that pieces not tabbed down when cutting out (profiling etc) has a great risk of breaking bits when they pop lose ?
[07:57:56] <Tom_itx> the possiblity is there but once they cut lose they generally move out of the way since they have the cutter width clearance as a place to go
[07:58:20] <Tom_itx> it's probably not good practice
[07:59:08] <mrsun_> Tom_itx: well when cutting out like 200 little small profiled pockets its nt realy fun to cut tabs either :/
[07:59:40] <mrsun_> heard it banging around quite hard sometimes :P
[07:59:48] <Tom_itx> is there a different way to do it?
[08:00:09] <mrsun_> dont know realy ... do full pockets and have the piece take 10x the time
[08:00:17] <Tom_itx> use air to clear the part
[08:11:07] <Tom_itx> have you broken bits because of it?
[08:11:58] <jthornton> well this is interesting, I started the linuxcnc config picker and picked on then when it started to run the computer dropped out of
[08:12:00] <jthornton> x
[08:12:10] <archivist> all depends if there is any climbing done that pulls a part ii
[08:20:11] <jthornton> all is not well with this computer :(
[08:28:26] <mrsun_> Tom_itx: not yet . .but havent done much of it yet :P
[08:30:25] <jthornton> logger[mah], log
[08:30:25] <logger[mah]> jthornton: Log stored at http://linuxcnc.mah.priv.at/irc/%23linuxcnc/2015-01-24.html
[09:14:36] <Bushman> a thing i made just few minutes ago:
[09:14:39] <Bushman> https://grabcad.com/library/clamp-for-nut-for-trapezoidal-lead-screw-1
[09:20:37] <archivist> nut needs something to stop it sliding in the clamps
[09:20:57] <Bushman> see the 5'th hole?
[09:21:12] <Bushman> one of those conical counter screws will be there
[09:21:25] <Bushman> just need to drill the nut a bit...
[09:21:56] <Bushman> maybe i will add all the screws to the project later :P
[09:22:07] <archivist> because later you will want to slit the nut to take up wear :)
[09:22:36] <archivist> some have flanges for that
[09:24:22] <Bushman> there are some flanged brass nuts for sale but not with slack/play reduction
[09:24:43] <Bushman> only some plastic ones... and quite pricey compared to this
[09:25:25] <archivist> a single slit in one side of the nut will allow the clamps to adjust a bit
[09:25:36] <Bushman> i know
[09:25:48] <Bushman> but i'm considering other options too
[09:33:58] <Bushman> like cutting the nut in half and making some clever mechanism to rotate one of them a tad and then clamp it back again
[09:36:30] <archivist> or a spring above expected cutting force, I have a worn screw that when adjusted locks up at the ends and is loose in the middle
[09:37:13] <Bushman> yea, i'm worried about that too
[09:37:26] <archivist> on a machine made in 1942, boss said it was almost new!
[09:37:53] <Bushman> lol
[09:37:57] <Bushman> almost
[09:38:59] <archivist> I cannot comprehend how he thought it had done little work
[09:39:59] <Bushman> well, i was working on CNC from 1973
[09:40:26] <Bushman> this bitch had some random twitches
[09:41:41] <Bushman> once when boring cast iron it twitched in the outward direction f***ing up the piece
[09:42:25] <Bushman> and by twitch i mean go few milimeters in random direction and hand up still runing the main motor
[09:42:53] <Bushman> (lathe)
[09:43:13] <Bushman> *hang up
[09:49:21] <archivist> we had a mechanical gear cutting machine at that place too, the dividing would throw an extra bit in for fun now and again
[09:50:01] <archivist> this beast http://www.collection.archivist.info/searchv13.php?searchstr=kopfer
[09:54:55] <archivist> had to take boss to hospital to get a .8MOD groove stitched because it liked flesh too
[10:05:05] <Tom_itx> jthornton you're gettin off to a rough start today
[10:14:24] <Tom_itx> drew or machined?
[10:14:36] <Tom_itx> woops, scrollback
[11:54:15] <Bushman> https://grabcad.com/library/hexagon-head-screw-iso-4017-din-933
[11:54:31] <Bushman> could someone convert this from solidworks to something FC can digest?
[11:54:53] <Bushman> s/FC/FreeCAD/
[11:55:41] <FinboySlick> Bushman: It should be very easy to model though.
[11:56:33] <Bushman> i'm lazy and there are people who have already modeled those basic parts
[11:56:56] <Bushman> it just happens most of the screws on grabcad are in solidworks format
[11:57:14] <Bushman> like this one: https://grabcad.com/library/caphead-bolt-and-dowel-set-1/files/M4%20x%2040mm%20CAPHEAD%20BOLT.SLDPRT
[11:57:27] <Bushman> pretty much what i need
[11:57:52] <Bushman> i could fix my model to accept those directly in no time.
[11:58:10] <JT-Shop> Tom_itx, I just ignore butt heads like that
[12:01:21] <pcw_home> "never wrestle with a pig, you get dirty and besides the pig likes it"
[12:02:46] <JT-Shop> like never argue with an idiot, they bring you down to their level and win from experience
[12:04:14] <Bushman> heh
[12:04:19] <Bushman> i like that quote
[12:04:21] <pcw_home> Yep same sensible idea
[12:06:09] <Bushman> hmm...
[12:06:22] <Bushman> plenty of m8, plenty of m6...
[12:06:32] <Bushman> but no m4 bolts that i can use :(
[12:07:34] * JT-Shop goes to find another pcie video card or take a nap which ever comes first
[13:27:56] <DGMurdockIII> Hi guys
[13:28:51] <DGMurdockIII> Any one now any good cnc drill bit starter kits
[13:31:21] <archivist> I dont remember ever seeing a drill kit aimed at cnc
[13:31:37] <XXCoder> yeah probably standard kits would do?
[13:31:45] <XXCoder> like at lowes or something
[13:32:44] <renesis> go to harbor freight and get the titanium nitride full set
[13:32:55] <PetefromTn_> while I am LOATHE to say it harbor freight now sells a cobalt mix drill index set for like a hundred bucks that is not bad. If you get one of these you can have a good start
[13:33:00] <renesis> fractional, lettered and numbered, theyre HSS
[13:33:05] <archivist> probably more important to get the right drills for the materials you work with
[13:33:16] <renesis> then as you wear them out, replace with the import stuff at enco
[13:33:34] <renesis> its the harbor freight stuff is about the same quality as enco import stuff
[13:33:38] <DGMurdockIII> http://www.toolstoday.com/p-6231-18-pc-cnc-signmaking-advanced-router-bit-set-14-inch-shank.aspx?&variantids=11628,0&keywords=AMS-132
[13:33:49] <DGMurdockIII> Was looking at that
[13:34:10] <PetefromTn_> you said drill bit kit
[13:34:10] <renesis> yeah thats some crazy shit
[13:34:13] <renesis> ya
[13:34:53] <renesis> thats expensive
[13:35:12] <renesis> you can buy most of that shit individually for less
[13:35:12] <_methods> they like to rob sign people
[13:35:22] <_methods> they know they don't know any better
[13:35:55] <_methods> poor woodworkers get it too
[13:35:58] <DGMurdockIII> Yeah I now that $$
[13:36:04] <renesis> like, id rather have 5 of the endmill that i need than a set of 10 random ones, one each
[13:36:10] <_methods> i see them sell them cat40 toolholders for silly prices
[13:36:25] <_methods> they could buy them from msc for cheaper and msc is still a rip off
[13:37:03] <renesis> you can get amaerican carbide bits for like $20/ea for little stuff like that
[13:37:16] <renesis> american
[13:37:20] <DGMurdockIII> Link me
[13:37:24] <renesis> murkin.
[13:38:01] <renesis> http://www.2linc.com/engraving_tools_additional.htm
[13:38:20] <_methods> man $500 for that lol
[13:38:24] <_methods> that's just brutal
[13:38:47] <renesis> http://www.2linc.com/endmills_aluminum_3fl_std.htm
[13:39:30] <DGMurdockIII> I just need stuff to cut metal and plexiglass
[13:39:43] <renesis> ive gotten half round and pyramid engraving cutters from them, stuff with .005 tips, worked great
[13:39:54] <renesis> okay well also there is...
[13:41:07] <DGMurdockIII> To make boxes or holes in then
[13:41:16] <renesis> http://www.ebay.com/itm/3mm-Shank-3mm-CED-Tungsten-Carbide-Cutter-Rotary-File-Bur-Burr-Grinding-20Pcs-/161261902056?pt=LH_DefaultDomain_0&hash=item258bf558e8
[13:42:18] <_methods> what kind of machine are you using to cut this stuff with?
[13:42:25] <renesis> http://www.ebay.com/itm/5-PCS-YG1-4-FLUTE-SOLID-CARBIDE-1-8-DIAMETER-END-MILL-X-1-2-LOC-X-1-1-2-CNC-BIT-/130911760434?pt=LH_DefaultDomain_0&hash=item1e7af2f032
[13:42:34] <DGMurdockIII> I'll show u
[13:43:01] <_methods> for plexi i'd get those single flute upcut bits
[13:43:35] <renesis> guy selling carbide on ebay is gone
[13:43:53] <_methods> and the type of metal you are cutting will determine what you need for end mill geometry
[13:44:07] <renesis> plexi you just want to keep it cool
[13:44:09] <_methods> so hard to recommend end mills without knowing what metal you plan to cut
[13:44:50] <renesis> either feed fast and spin kind of medium slow, or use water based lube or something
[13:44:57] <renesis> dish soap works
[13:47:27] <DGMurdockIII> http://www.cncrouterparts.com/standard-cnc-machine-kits-c-46_29.html
[13:47:46] <DGMurdockIII> That the machine
[13:48:37] <renesis> the uprights are steel?
[13:48:52] <renesis> for a lighter machine thats looks pretty good
[13:49:58] <DGMurdockIII> Yes i think there steel
[13:51:15] <_methods> so you want to mill aluminum and plexiglass?
[13:51:36] <_methods> most of the stuff renesis just recommended will work well on that machine
[13:52:38] <_methods> get some 2 or 3 flute end mills for the aluminum and some single flute spiral upcut bits for the plexi and you should be good to go
[13:53:42] <DGMurdockIII> Yes_methods
[13:58:36] <renesis> dgmurdockiii: but yeah for aluminum, i would get a bottle of rutlick water based lube and itll last forever, mix it in a spray bottle, and just squirt
[13:59:09] <DGMurdockIII> Ok
[13:59:11] <renesis> and ive used that and just regular dish soap
[13:59:19] <renesis> for acrylic
[14:00:01] <renesis> and i mostly use 4 flute carbide endmills for everything
[14:00:36] <roycroft> i use wd40 when machining aluminium
[14:00:39] <renesis> i guess some people have all sorts of reasons to use shit other than carbide, but fuck that for little cnc
[14:00:47] <roycroft> it works better than anything else i've ever tried
[14:01:05] <renesis> yeah i dont like the smell and my machine is in a studio apartment
[14:01:15] <renesis> it does work well as a cutting coolant, tho
[14:01:24] <renesis> prob its best use by far
[14:01:26] <roycroft> it does have a strong odor
[14:01:30] <renesis> yeah
[14:01:43] <roycroft> i machine in a garage with a big door
[14:01:46] <renesis> i like it but itll give me a headache =\
[14:02:26] <renesis> but yeah, carbide breaks, its doesnt wear
[14:02:46] <renesis> like, the tips will chip off, and leave a sharp edge, and itll still cut
[14:02:58] <renesis> finish will be ass, might loud as fuck, but itll cut
[14:03:23] <roycroft> except when you're doing a plunge cut and it breaks off inside the part
[14:03:24] <renesis> hss and similar will wear down, and they kind of stop cutting and start chewing and it loads down the machine bad
[14:03:38] <renesis> and i have an open loop step machine so loading like that is the enemy
[14:03:51] <renesis> yeah dont do that
[14:04:01] <renesis> i usually do little spirals
[14:04:34] <renesis> center cutting is a thing but the speed of the center is like nothing and the edges cant stray sharp down there very long
[14:04:53] <renesis> its not a drill yo!
[14:23:18] <CaptHindsight> heh, you have to add "machining" or "cnc" to searches for water based lubricants or you won't find anything useful for machining
[14:23:51] <XXCoder> just use x-y lubricant lol
[14:24:11] <CaptHindsight> it is more readily available
[14:24:51] <CaptHindsight> and non-toxic
[14:26:18] <XXCoder> it would actually work?
[14:27:46] <_methods> man i forgot how funny super troopers is
[14:28:46] <CaptHindsight> XXCoder: http://householdproducts.nlm.nih.gov/cgi-bin/household/brands?tbl=brands&id=10001125
[14:30:51] <CaptHindsight> sorbitol, glycerin, propylene glycol, methylparabin.... the sorbitol might caramelize if it gets too hot
[14:31:45] <CaptHindsight> nah it boils at 290C
[14:38:09] <roycroft> just be sure to return the correct lube to the nightstand
[14:41:10] <renesis> http://www.acculuberustlick.com/pdf/msdsRustlick/msds_ws_11%205.17.13.pdf
[14:41:45] <renesis> i use this stuff, i may kill you, but they dont know how much it takes to kill a duck
[14:41:59] <renesis> they dont think its carcinogenic, tho
[14:42:04] <renesis> shrug
[14:42:36] <CaptHindsight> similar to the Mobilcut series
[14:43:17] <renesis> so like, its water/wax/oil?
[14:43:37] <renesis> shrug, it works, it doesnt fuck up acrylic
[14:43:50] <renesis> i cut it like maybe 20:1
[14:44:28] <CaptHindsight> yeah ~50% water the rest is oils, waxes and some soap to disperse them
[14:45:08] <renesis> i put it in a squirtbottle
[14:45:17] <CaptHindsight> I use one with a bactericide
[14:45:19] <renesis> like the shit cleaning ladies use for windex
[14:46:28] <CaptHindsight> that reminds me the HF pump died after a few hours use with it
[14:46:47] <renesis> that sucks
[14:47:14] <CaptHindsight> anyone found any aquarium pumps that survive cutting fluids well?
[14:47:35] <renesis> go to a local hydroponics shop
[14:47:59] <CaptHindsight> I think one overheated since the pump vanes still spin freely
[14:49:31] <SpeedEvil> CaptHindsight: you're sure the filter was good?
[14:49:41] <CaptHindsight> filter is fine
[14:50:31] <CaptHindsight> they are made so cheap maybe I just got one made early in the day
[14:51:46] <CaptHindsight> in China you don't want anything made in the morning since it could be the workers first time making/assembling/welding/soldering etc it
[14:52:22] <SpeedEvil> 6 year-olds take some time to get going in the morning.
[14:52:23] <CaptHindsight> it like in the US you didn't want a Monday or Friday made car
[14:56:46] <CaptHindsight> http://www.homedepot.com/p/Leaktite-5-gal-Screw-Top-Lid-5GAMMA6/203205720 these work out pretty well for converting a 5 gal pail int a coolant tank
[14:56:48] <XXCoder> https://i.chzbgr.com/maxW500/5084157952/h84C128E7/
[14:56:54] <XXCoder> reminds me of MAD lol
[14:57:36] <CaptHindsight> the back covers, I forgot about those
[14:57:39] <XXCoder> though it's not very good, you can see it on orginial
[15:02:29] <CaptHindsight> why was George Bush on every cover?
[15:04:09] <CaptHindsight> zeeshan: your white coating goes out Monday
[15:04:37] <zeeshan> thank you!
[15:04:49] * zeeshan is excited to try it out
[15:05:12] <zeeshan> Tom_itx: damn post office was closed
[15:05:19] <zeeshan> by the time i got there, package leaves monday :P
[15:06:28] <CaptHindsight> I feel like I have the flu back again or it would have made today's fedex
[15:06:45] <zeeshan> weather change
[15:07:16] <CaptHindsight> it's been nice for Jan here
[15:07:22] <CaptHindsight> >32F
[15:07:47] <Bushman> ok, made some updates, possibly improvements
[15:07:50] <Bushman> https://grabcad.com/library/clamp-for-nut-for-trapezoidal-lead-screw-1
[15:07:57] <Bushman> what do you guys think?
[15:09:13] <XXCoder> insane https://www.kickstarter.com/projects/elanlee/exploding-kittens/description
[15:09:20] <XXCoder> I backed it, why not lol
[15:12:49] <Jymmm> $3M funded.... for a card game ~Le Sigh~
[15:14:04] <XXCoder> it's theoatmeal effect
[15:15:04] <Jymmm> it's pathetic is what it is.... bastard! lol
[15:15:22] <XXCoder> lol
[15:15:49] <XXCoder> if it gets to 100k backers they will extend nsfw deck to full size
[15:16:00] <Jymmm> Funded $100K in less than an hour
[15:16:02] <XXCoder> less than 6k left
[15:17:43] <zeeshan> 20.1 A
[15:19:23] <Jymmm> I'm going to guess about $5.1M by Feb 19th
[15:19:41] <_methods> had $2m in 24hours
[15:19:48] <_methods> that's just silly
[15:20:09] <Jymmm> No, that's pretty fucking smart actually.
[15:20:18] <XXCoder> yeah
[15:20:20] <_methods> he's done well for himself
[15:20:23] <_methods> that's for sure
[15:20:26] <XXCoder> bulk cards is cheaper
[15:20:42] <XXCoder> with 100k backers thats 100k decks, big bulk = more profit per deck
[15:21:21] <zeeshan> dont b jealous!
[15:21:30] <Jymmm> He could even have them made in the US, as cutomsdecks are very common (think casinos)
[15:23:51] <CaptHindsight> I know guys that make custom games but they have trouble selling more than 100's
[15:24:10] <Jymmm> CaptHindsight: card games?
[15:24:20] <CaptHindsight> card and board
[15:25:14] <CaptHindsight> printing those decks will cost a few $$ ea
[15:25:53] <CaptHindsight> including the packaging, nice to seel that much without having to do much advertising
[15:26:01] <CaptHindsight> seel/sell
[15:26:58] <CaptHindsight> $35 for a pair of decks
[15:27:32] <XXCoder> nfsw will be only part deck, unless over 100k backers, which will happeb
[15:27:50] <XXCoder> it increased over 500 backers while we was chatting
[15:28:00] <XXCoder> er 400
[15:29:20] <Jymmm> I was thinking of using solid wire to attach, any other thoughts? http://img.dxcdn.com/productimages/sku_287251_2.jpg
[15:31:27] <renesis> make a pcb? because its pcb mount?
[15:31:32] <renesis> if wires, use hot glue
[15:31:57] <_methods> http://techno-logic-art.com/tower.htm
[15:32:02] <renesis> also flux, low temp, very quickly, else the contacts will shift a ton in the housing
[15:32:43] <renesis> also i dont use solid for anything, really, except solderless breadboard jumpers
[15:46:17] <Jymmm> _methods: what is that a clock?
[15:46:23] <Jymmm> _methods: you make it?
[15:46:56] <_methods> i guess it's insane
[15:47:02] <_methods> but i think it's supposed to be a clock
[15:47:16] <_methods> and no i didn't make that
[15:48:04] <PetefromTn_> Hey guys!!
[15:48:13] <_methods> i wonder if he's ever tempted to steal a diode out of it when he's short one in another project
[15:48:42] <PetefromTn_> I am oploading a neat video I made of something I did a little while ago on the CNC that I finally finished. I thought you guys might enjoy it....
[15:50:57] <Jymmm> My PS module arrived, mich smaller than I expected it to be
[15:51:03] <Jymmm> much*
[15:51:31] <Jymmm> even came with standoffs
[15:52:41] <Jymmm> It almost fits in an altoids tin, just slightly too high
[15:53:56] <zeeshan> cute
[15:55:11] <Jymmm> https://www.youtube.com/watch?v=yePhLQs0OGU
[15:55:32] <zeeshan> is his left hand
[15:55:35] <zeeshan> right next to the mains power?
[15:55:35] <zeeshan> lol
[15:56:04] <Jymmm> No, it's DC-DC
[15:56:16] <zeeshan> O
[15:56:57] <Jymmm> You can take any old brick DC PS and make it ia digital variable CC/CV PS
[15:57:38] <Jymmm> http://www.amazon.com/Digital-Constant-Voltage-Current-Step-Down/dp/B00GYVDSY4
[15:57:42] <PetefromTn_> http://vid150.photobucket.com/albums/s83/matospeter/SAM_0728_zpsxumwths2.mp4
[15:58:16] <_methods> ah nice you got it finished finally
[15:58:44] <Jymmm> PetefromTn_: where did you buy the base from?
[15:58:46] <_methods> wow came out good
[15:59:52] <PetefromTn_> yeah finally finished it hehe
[16:00:09] <PetefromTn_> I got the base on ebay and it worked out really nice I thought.
[16:00:21] <Jymmm> PetefromTn_: Cool. Link?
[16:00:22] <PetefromTn_> it is very slim and tight looking
[16:00:25] <renesis> petefromtn_: cool
[16:00:47] <PetefromTn_> thanks guys glad you like it. It is actually really hard to get a good video of it..
[16:01:39] <renesis> maybe turn more lights on in the rooms
[16:02:05] <PetefromTn_> http://www.ebay.com/itm/360914944106?_trksid=p2059210.m2749.l2649&var=630271391966&ssPageName=STRK%3AMEBIDX%3AIT
[16:02:54] <PetefromTn_> yeah we blacked out the curtains as much as we could and I lowered the brightness volume as much as possible and you can see it still almost washes out the video
[16:03:00] <Jymmm> PetefromTn_: thanks.
[16:03:02] <PetefromTn_> I think you can get the idea tho...
[16:03:05] <PetefromTn_> sure man.
[16:03:16] <renesis> petefromtn_: no the other way
[16:03:28] <renesis> more light, not less, so theres less of a diff
[16:03:41] <PetefromTn_> maybe..
[16:04:01] <PetefromTn_> I think you can get the idea tho from the video.. that is actually like the fourth try at the video LOL
[16:04:10] <PetefromTn_> I am kinda over making any more now hehe
[16:04:18] <renesis> ha yeah not a bid deal, that came out awesome
[16:11:21] <PetefromTn_> thanks man... She loved it!
[16:16:13] <renesis> cool
[16:16:50] <zeeshan> for a keyboard and mouse
[16:16:56] <zeeshan> better to do 2 extension cables
[16:16:58] <zeeshan> or 1 hub
[16:17:14] <Tom_itx> zeeshan you slept in too long!!
[16:17:20] <zeeshan> Tom_itx:
[16:17:20] <zeeshan> haha
[16:17:27] <zeeshan> its saturday!
[16:17:35] <Tom_itx> i made it to the post
[16:18:00] <Tom_itx> actually i'm in no rush
[16:44:42] <Deejay> gn8
[16:56:55] <renesis> zeeshan: usb?
[16:57:17] <renesis> do extensions and heatshrink the connectors
[16:59:55] <PetefromTn_> zeeshan something to consider is one of the all in one dustproof and liquid proof keyboards like I got for the CINCI.. Mine has a touch pad and keypad..
[17:00:11] <PetefromTn_> http://www.ebay.com/itm/DSI-Silicone-Industrial-Waterproof-USB-Keyboard-with-Touchpad-KB-107-/311127208518?pt=PCA_Mice_Trackballs&hash=item4870a07246 this one looks like the exact same one I have
[17:00:48] <zeeshan> 51!
[17:01:12] <PetefromTn_> I think I paid more than that for mine actually..
[17:01:22] <zeeshan> yea i wouldnt pay more than 10 bux for one
[17:01:23] <zeeshan> lol
[17:01:36] <PetefromTn_> you get what you pay for man
[17:01:38] <zeeshan> if it fries, replace! :P
[17:12:21] <jdh> http://images.craigslist.org/00l0l_dI4TPYjRsQ9_600x450.jpg
[17:12:28] <jdh> pete needs that
[17:13:41] <PetefromTn_> shiiitt I don't have enough toolholders to fill one turn in that beast LOL
[17:14:11] <jdh> 120 slots
[17:14:26] <Tom_itx> we had a 119 tool belt on one of the Okumas
[17:14:32] <PetefromTn_> yeah I think I have like 24
[17:14:33] <renesis> for $50 i would buy a cherry keyboard
[17:14:39] <XXCoder> 119 tools? dang
[17:14:45] <renesis> but 90% of the time i rock a $12 lofitech keyboard
[17:14:45] <jdh> http://wilmington.craigslist.org/tls/4840382407.html
[17:14:51] <XXCoder> and I thought hurco I run's 20 slots was plenty
[17:14:52] <Tom_itx> it was housed in a cage behind the machine
[17:14:52] <renesis> logitech
[17:15:18] <Tom_itx> that one had a double swing arm to change tools
[17:15:28] <Tom_itx> pick one and place the other in one fell swoop
[17:16:23] <_methods> wow pretty good deal at $135k
[17:16:27] <_methods> with all the tooling too
[17:16:47] <_methods> 3 horizontals for $135k
[17:18:53] <_methods> i'm sure he just wants it all out and would probably do it for less than that
[17:18:57] <Tom_itx> cat 50
[17:19:02] <_methods> amen
[17:19:19] <Tom_itx> i bet they couldn't keep em busy enough
[17:19:35] <_methods> yeah you gotta feed those monsters
[17:20:11] <Tom_itx> there was a shop here with a pallet changer with a conveyor and enormous toolchanger
[17:20:28] <Tom_itx> you could schedule jobs on it but they didn't utilize it's capacity
[17:20:31] <Tom_itx> and now they're gone
[17:21:25] <Tom_itx> iirc it had like 6 or 8 toumbstones
[17:25:31] <Tom_itx> they dug a pit for it and filled it with silicone for a dampener
[18:17:53] <JessicaRN> hey folks, I'm looking for a toolpath optimizer for .plt files. any thoughts? I found BOCNC but I cant read german
[18:27:24] <_methods> just convert it to dxf or dwg and have your way with it
[18:28:21] <JessicaRN> what I'm trying to do is reduce cutting time when processing a .plt file on my laser cutter.
[18:28:55] <JessicaRN> it currently cuts parts willy-nilly instead of tracking down the cut in a logical fashion
[18:30:14] <JessicaRN> so, I'm looking for a utility to re-write the plt file in an optimized manner where after cutting a path the laser jumps to the next closest path to it's current position
[18:30:27] <JessicaRN> capish?
[18:36:41] <_methods> like i said i'd convert it to a dxf or dwg and work with it that way
[18:36:58] <_methods> your cutter only works with plt?
[18:37:23] <JessicaRN> no, but that is the easiest way to generate output.
[18:37:50] <JessicaRN> i usually get corel files, and I can easily dump them out to .plt files.
[18:38:34] <_methods> what nesting software?
[18:38:54] <JessicaRN> the problem is, if my image is made up of 2000 paths there doesn't seem to be any logic to the order they are cut.
[18:39:34] <JessicaRN> so the laser head jumps all over the job while cutting. it slows the whole process down
[18:39:34] <_methods> you can't modify your pathing?
[18:39:43] <_methods> i'm sure it does lol
[18:40:32] <_methods> well what toolchain are you using that might help someone in here identify a better solution for you
[18:40:52] <JessicaRN> If I can modify it, I sure don't know how. I've read that there are apps that will read the generated plt file and reorder the shapes therein in order in optimize cutting speed.
[18:42:17] <JessicaRN> well, for these images I'm using corel. i open a bitmap in corel, trace it, and output the trace to a .plt file
[18:42:27] <JessicaRN> my laser can read that
[18:44:41] <zeeshan> http://i.imgur.com/lx3lint.jpg
[18:44:43] <zeeshan> :-)
[18:45:17] <JessicaRN> door froze shut?
[18:49:05] <zeeshan> i guess so lol
[19:15:59] <LeelooMinai> It's a safety lock - you take it home so no one can open the door any more
[19:22:37] <zeeshan> LeelooMinai: less talk more CNC
[19:22:38] <zeeshan> !
[19:22:50] <LeelooMinai> Watching music video now:)
[19:23:05] <zeeshan> im watching predestination
[19:23:08] <zeeshan> interesting so far
[19:23:36] <LeelooMinai> Brutal playing is brutal
[19:28:02] <malcom2073> So, which mesa board combo do I need to run a servo driven knee style CNC? 5i25 + 7I77?
[19:28:23] <Tom_itx> probably
[19:28:32] <Tom_itx> is the 7i77 a servo board?
[19:28:49] <malcom2073> seems like that's the servo daughter for the 5i25
[19:29:09] <Tom_itx> they had a stepper board and a servo one for it i know
[19:29:38] <Tom_itx> get the kit
[19:33:17] <malcom2073> I need to verify these servo cards use analog input for their control. The system used to run EMC through a servo2go isa card... witing to see if the guy can find his notes on how it was hooked up heh
[19:38:30] <malcom2073> Yep, they're 10v +/- signal, awesome
[19:40:28] <zeeshan> 7i77 + 5i25
[19:40:31] <zeeshan> 5i25 for pci
[19:40:34] <zeeshan> 6i25 for pci-e slot
[19:40:47] <zeeshan> 7i77 for analog output to servo drive
[19:41:10] <malcom2073> I think I want to stick with pci
[19:54:04] <XXCoder> jeez, that kickstarter is at 95,260 supporters and 3.7 million now
[19:54:12] <XXCoder> and only been 4 days
[20:05:57] <LeelooMinai> Damn, something weird is happening to Canadian dollar - seems like every day I buy stuff from internet in US dollars I pay more:)
[20:06:25] <XXCoder> they have time machine and adjust according as soon as you plan to buy something ;)
[20:06:43] <LeelooMinai> IN the past it was more or less similar...
[20:07:07] <zeeshan> yea its like .78 cad = 1 usd
[20:07:14] <zeeshan> i started buying stuff locally
[20:07:40] <XXCoder> thanks for warning I'll wait on canada buys ;)
[20:07:59] <zeeshan> i meant
[20:08:04] <zeeshan> .78 usd = 1 cad
[20:08:07] <LeelooMinai> Hmm, just read that there is some situation with oil prices that caused this
[20:08:26] <zeeshan> yea and bank of canada dropped interest rate unexpectingly
[20:08:29] <LeelooMinai> Wonderful
[20:09:01] <LeelooMinai> Was just going to buy nice VFD:)
[20:21:02] <_methods> some situation with oil lol
[20:21:51] <_methods> i wonder if that's vladimir putin calls it hehe
[20:37:23] <XXCoder> splitville
[20:37:27] <_methods> hehe
[20:37:31] <_methods> it's the weekend
[20:37:41] <XXCoder> split pea soup
[20:37:41] <PetefromTn_> lovely..
[20:37:41] <_methods> the skript kiddiez are actin up
[20:41:48] <XXCoder1> lovely
[20:42:01] <_methods> das splitz
[20:42:52] <Jymmmm> IT'S WORKING!!! IT'S WORKING!!! Go my minions, continue to do my bidding!!!
[20:42:57] <XXCoder1> the split compels you
[20:43:13] <_methods> topic Jymmmm is still gay
[20:43:22] <_methods> oops
[20:43:40] <Jymmmm> _methods: You knows whats worse?
[20:43:50] <_methods> no what?
[20:44:05] <PetefromTn_> huh Jimmy's gay?
[20:44:12] <_methods> it's tru
[20:44:16] <MrAsshole> _methods: Me. You know whats worse than that?
[20:44:25] <_methods> hehe no what?
[20:44:33] <PetefromTn_> figures...
[20:44:47] <_methods> hold on i'm trying to take over freenode
[20:44:58] <Tom_itx> it's the weekend! jymmm is uncloaked!
[20:45:05] <MrAsshole> _methods: Me with ops =)
[20:45:05] <PetefromTn_> first freenode....then.....THE WORLD!!
[20:45:11] <_methods> oh noes
[20:45:40] <XXCoder1> ops = over-powered shit ;)
[20:46:03] * MrAsshole sets mode: +pink-panties _methods
[20:46:09] <_methods> hahaha
[20:46:14] <XXCoder1> lol
[20:46:16] <_methods> you got my pics?
[20:46:43] <Jymmm> _methods: Yes, some imagines are just burned in
[20:46:54] <Jymmm> and can never be forgotten
[20:46:54] <_methods> sets mode +O _methods
[20:48:21] * _methods trout slaps _methods
[20:48:29] <_methods> oops
[20:54:30] <Tom_itx> zeeshan|2 were you planning to connect that board directly to the fpga pins?
[20:55:47] <_methods> heheh
[20:55:51] <_methods> ahh the games
[20:56:06] <Tom_itx> _methods put that friggin plug down now!
[20:56:13] <_methods> no kidding
[20:56:57] <Tom_itx> ok it looks like i lose 4 outputs with the S board over the regular one
[20:57:15] <PetefromTn_> s board?
[20:57:18] <Tom_itx> rather they are remapped to pwm with dir and enable
[20:57:26] <Tom_itx> 7i47 7i47S
[20:59:04] <Tom_itx> question is if it will overload the fpga if i use stepgen, pwmgen, quadrature, sserial, ioporttag, ledtag functions
[20:59:29] <_methods> that's a pcw question for sure lol
[20:59:38] <Tom_itx> i know
[20:59:46] * _methods goes back to dismantling freenode
[20:59:49] <Tom_itx> i don't know the xilinx warnings well enough to tell
[21:00:01] <PetefromTn_> well actually I could answer it....but I would be WRONG!
[21:00:18] <Tom_itx> it would be a timing issue
[21:00:45] <_methods> or not enough timers issue lol
[21:00:56] <Tom_itx> however it looks like this little board uses stepgen instead of pwmgen for the pwm signal
[21:01:24] <Tom_itx> so i may not need pwmgen
[21:02:07] <_methods> so if you're using one of those mesa boards do you have to worry about jitter?
[21:02:45] <Tom_itx> if you load too many hostmot2 functions in a bitfile you can get timing errors
[21:03:06] <Tom_itx> _methods, no not so much
[21:03:15] <Tom_itx> you use the servo thread for those cards
[21:03:19] <_methods> so you can get away with using a laptop?
[21:03:26] <_methods> and a mesa card
[21:03:36] <Tom_itx> i dunno, depends on the laptop i suppose
[21:03:45] <Tom_itx> generally not, i don't know anybody using one personally
[21:03:53] <_methods> i was going to try with one
[21:04:03] <Tom_itx> the parport may not be compatible either
[21:04:18] <_methods> i ordered a mini-pcie to pcie card
[21:04:21] <_methods> with cable
[21:04:29] <_methods> to break out the mini pcie slot on the laptop
[21:05:19] <_methods> i'm sure it won't work but i'll give it a shot
[21:05:49] <Tom_itx> you can always send me the board if it doesn't
[21:05:50] <_methods> would be nice to put some old laptops to use though for linuxcnc
[21:05:59] <_methods> haha i plan on using the board
[21:06:34] <_methods> if my laptop experiment fails i'll just use a real computer lol
[21:26:37] <Tom_itx> Q. when you load the config line config=num_stepgens=x where do you specify the type of output "step_type" ?
[21:26:51] <Tom_itx> and what is the default?
[21:27:08] <Tom_itx> i assume it is step/direction since i didn't specify one
[21:34:37] <Tom_itx> what ini section do you put spindle control parameters?
[21:35:31] <Jymmm> FAAAAARK... The battery holder doesn't accept protected cells =(
[21:54:53] <pcw_home> Tom_itx: step type is a parameter
[21:55:36] <Tom_itx> some of those parameters are specified in the axis sections though
[21:55:53] <Tom_itx> this board uses a stepgen signal to drive the adc
[21:56:07] <Tom_itx> for spindle control
[21:56:49] <Tom_itx> so i could put the step_type as part of the stepgen parameters in the config line?
[21:57:09] <Tom_itx> pretty sure the one i need it the default anyway
[21:57:48] <pcw_home> its a hal parameter so set with a setp statement in the hal file
[21:57:57] <Tom_itx> ahh ok
[21:58:12] <Tom_itx> do you know what the default type is?
[21:58:14] <Tom_itx> 0?
[21:58:26] <pcw_home> step/dir
[21:58:29] <Tom_itx> ok
[21:58:34] <Tom_itx> that's 0 i think
[21:58:51] <Tom_itx> so i don't really even need to specify it
[21:59:38] <Tom_itx> however i specify the stepspace and steplen for each axis in the axis sections.
[21:59:52] <Tom_itx> where would i specify it for the spindle?
[21:59:57] <pcw_home> no, but for rate controlled spindle DAC you may want quadrature mode
[22:00:15] <Tom_itx> it says it want's velocity mode
[22:00:39] <pcw_home> sure (thats a parameter as well)
[22:01:14] <Tom_itx> they have an example hal file but it's for the software stepgen. i'm sure the hostmot2 one is similar
[22:01:41] <Tom_itx> ie setp stepgen.5.stepspace x
[22:01:43] <pcw_home> note that the ini sections are mostly pretty arbitrary (just a convenience) so you can make up your own sections
[22:02:32] <Tom_itx> did you see my question about hostmot2 components in the bit file above?
[22:02:39] <Tom_itx> i wonder if that's too many for it
[22:03:00] <Tom_itx> with stepgen, pwmgen, quadrature, sserial etc in it
[22:03:28] <Tom_itx> i don't actually think i need pwmgen now
[22:03:33] <Tom_itx> so it should be ok
[22:04:04] <pcw_home> no, you can put pretty much anything you want until you run out of space
[22:04:21] <Tom_itx> i got a timing error on one i did early on
[22:04:32] <Tom_itx> that's why i was wondering
[22:04:44] <Tom_itx> i don't recall the exact error
[22:05:09] <pcw_home> The compiler reported that it did not meet timing?
[22:05:14] <Tom_itx> yes
[22:05:26] <Tom_itx> i wound up changing it
[22:05:37] <Tom_itx> i think i removed pwmgen since i wasn't using it
[22:06:53] <Tom_itx> i see the 7i47s uses 4 of the io for the spindle signal
[22:07:06] <pcw_home> you can often fix this by tweaking the build parameters (and some timing errors are bogus. it think most ucf files have fixes for bogus error reports but not all)
[22:07:29] <pcw_home> yes PWM/DIR/ENA/SPARE
[22:07:44] <pcw_home> so 4 of the TX lines are used
[22:07:54] <Tom_itx> well if i did something like that which i don't think i'll need to i may get you to look it over before i loaded it to the card
[22:08:09] <Tom_itx> yeah i saw that
[22:08:37] <pcw_home> also are you optimizing for speed or area?
[22:08:43] <Tom_itx> speed
[22:08:49] <Tom_itx> you warned me about that
[22:09:05] <pcw_home> ok it might be worth looking at
[22:09:29] <Tom_itx> i don't have the hardware right now anyway, just preparing
[22:09:32] <pcw_home> for which card?
[22:09:46] <Tom_itx> something zeeshan|2 is sending me
[22:09:56] <Tom_itx> cnc4pc spindle card
[22:10:28] <pcw_home> I mean for whcich card did you get a timing error?
[22:10:32] <Tom_L> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=25&products_id=58
[22:10:35] <Tom_itx> oh
[22:10:45] <Tom_itx> it was on the old 7i43 7i47 combination
[22:11:00] <Tom_itx> i'm not using the 7i43 anymore
[22:11:12] <Tom_itx> it's pretty well toast
[22:11:21] <pcw_home> probably less likely on a 7I90
[22:11:29] <Tom_itx> yeah
[22:11:41] <Tom_itx> it's got a faster clock doesn't it?
[22:12:17] <pcw_home> Yes Clocklow is 100 MHz, ClockHigh is 200 MHz
[22:12:33] <Tom_itx> i was just looking at the 7i47S as a 2nd card but i don't think i need it
[22:13:07] <Tom_itx> i'm keeping the one you just sent as a spare since i fixed the old one
[22:14:02] <pcw_home> Spartan 6 CPU clock is 100 MHz also for things that have CPUs (sserial, resolver, serial,Ethernet)
[22:15:03] <pcw_home> looking forward to using Artix chips, Clocklow/CPU clock will be 200 MHz
[22:16:14] <Tom_itx> you may have to start changing your board designs for those
[22:17:00] <pcw_home> They have ADCs built in which is nice
[22:21:12] <Tom_itx> seems i may be able to use the stock sherline speed control for this
[22:30:14] <Tom_itx> pcw_home, what boards are you gonna start putting those in?
[22:31:17] <pcw_home> higher end at first (3x20 replacement with USB3 interface is one planned)
[22:31:29] <LeelooMinai> pcw_home: Is Artix supposed to be replacement for Spartans or you just want to move to more powerful FPGA?
[22:32:00] <pcw_home> its effectively spartan 7
[22:32:46] <LeelooMinai> Someone just mentioned it in #fpga so I was wondering. That is someone wrote that Spartan 6 is phased out and I was wondering what is the replacement.
[22:33:37] <pcw_home> Nonsense spartan 6 will be available for probably 10 or more years
[22:33:58] <pcw_home> we have 0 issues getting Spartan 2
[22:34:02] <LeelooMinai> Right, well, I thought it was weird - it seems to be very popular right now.
[22:34:28] <pcw_home> and most Artix chips are barely available now
[22:35:17] <pcw_home> I think you can still get 4000 series Xilinx (from the late 80s?)
[22:35:24] <zeeshan|2> hi tom
[22:35:32] <Tom_itx> z
[22:35:39] <LeelooMinai> lol, I did not even know there were FPGAs in 80s
[22:35:41] <zeeshan|2> i think you only give it step, gnd, cw and ccw
[22:35:41] <zeeshan|2> wires
[22:35:59] <zeeshan|2> and it controls the relays and stuff
[22:36:01] <zeeshan|2> accordingly
[22:36:11] <Tom_itx> zeeshan|2, if it feed the relay with cw ccw, what's the point of both signals?
[22:36:18] <Tom_itx> one will be active by default
[22:36:22] <zeeshan|2> oh it says
[22:36:25] <zeeshan|2> en and dir
[22:36:27] <zeeshan|2> nm
[22:36:37] <zeeshan|2> relay 1 on/off enable signal
[22:36:41] <zeeshan|2> relay 2 dir signal
[22:36:51] <Tom_itx> were you gonna feed it straight from the fpga?
[22:36:56] <zeeshan|2> i didnt have fpga
[22:37:02] <zeeshan|2> i had a probotix breakout board
[22:37:04] <Tom_itx> oh
[22:37:14] <zeeshan|2> was gonna feed directly from parallel port pretty much
[22:37:21] <Tom_itx> well part of those signals are opto isolated but not all
[22:37:31] <zeeshan|2> pretty sure
[22:37:33] <zeeshan|2> this board is isolated
[22:37:35] <zeeshan|2> so that isnt a prob
[22:37:36] <Tom_itx> unless i read it wrong
[22:37:48] <pcw_home> Xilinx 2000 series was 1985, 4000 series was 1991
[22:37:55] <zeeshan|2> Opto - isolated output signals. The analog and CW and CCW signals are optically isolated, so this board can be used with drives that make grounds common with the mains that drive the VFD or motor
[22:38:01] <Tom_itx> i got an old old xininx board
[22:38:21] <Tom_itx> ahh ok
[22:38:33] <Tom_itx> what about enable?
[22:39:25] <Tom_itx> output signals...
[22:39:35] <pcw_home> probably either CW or CCW asserted is enable
[22:39:42] <zeeshan|2> yea
[22:39:45] <zeeshan|2> as long asits getting a signal
[22:39:47] <zeeshan|2> it spins one way
[22:39:51] <zeeshan|2> and vise versa
[22:39:52] <pcw_home> (like VFDs with FOR and REV)
[22:39:54] <Tom_itx> haha xc95108
[22:40:29] <pcw_home> thats a CPLD
[22:40:37] <pcw_home> a 5V one at that
[22:41:00] <pcw_home> 108 macrocells
[22:41:04] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/temp/xilinx1.jpg
[22:41:18] <Tom_itx> i played with that a bit a loooonnng time ago
[22:41:48] <Tom_itx> it's got a jtag on it i could still use
[22:42:30] <Tom_itx> kinda cumbersome for that
[22:44:11] <pcw_home> we still use those on one of our older cards (they have 48 mA low side drive, and we have a card that emulates 4x beefy 8255s)
[22:44:51] <pcw_home> (96 I/O using 2x 95108s)
[22:45:27] <pcw_home> the 5V parts are hard to get now and expensive now
[22:47:14] <zeeshan|2> http://www.mini-lathe.com/kx3/bellows.jpg
[22:47:19] <zeeshan|2> i really dislike these kind of way covers :/
[22:47:22] <zeeshan|2> such a pain to clean
[22:47:33] <pcw_home> ahh that DB25 is a parallel port JTAF wiggler connection
[22:47:40] <pcw_home> JTAG
[22:47:45] <XXCoder1> zee I saw one machine that has those, AND another plastic sheet covering it
[22:47:56] <XXCoder1> just flat sheet thats enough to make cleaning easy
[22:47:56] <zeeshan|2> ah
[22:48:43] <Tom_itx> pcw_home yeah
[22:49:00] <Tom_itx> you can disconnect it from the board and use it externally as well
[22:49:21] <zeeshan|2> http://www.maschinensucher.de/ma2/bilder/MIKRON-WF21C/1851330-2.jpg
[22:49:25] <zeeshan|2> im missing that Z axis cover
[22:49:29] <zeeshan|2> its like 400 bux to replace :/
[22:49:37] <XXCoder1> ouch
[22:49:41] <zeeshan|2> im thinking of just bolting on a piece of plastic sheet
[22:49:42] <zeeshan|2> lol
[22:49:47] <zeeshan|2> for now
[22:50:10] <LeelooMinai> You can use an old accordeon too
[22:50:12] <Tom_itx> pcw_home, the schematic for those are up there somewhere
[22:50:48] <pcw_home> wonder if it got crumpled up at some point
[22:51:16] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/xilinx/digilent/
[22:51:59] <pcw_home> Tom_itx: remind me next week and I'll send you a couple PCBs for an improved type 3 JTAG interface
[22:52:16] <Tom_itx> you don't recall what chips are on it?
[22:52:41] <pcw_home> I think a HC14 and a HC125
[22:52:46] <Tom_itx> k
[22:52:52] <Tom_itx> smt?
[22:52:54] <pcw_home> (surface mount)
[22:52:58] <Tom_itx> i probably have some somewhere
