[00:25:08] <Contract_Pilot> The fans on them are temp controlled.
[00:25:38] <Contract_Pilot> Warmer it gets the faster it goes till about 200C then pop goes the controller at 6V
[00:26:17] <Contract_Pilot> Unplug the fan and measure the pins!
[00:26:50] <Contract_Pilot> Poor Design if it gets hot.
[00:27:15] <Contract_Pilot> But was able to get the other 2 to dunp in to a 8amp load.
[00:27:30] <Contract_Pilot> Need a better dummy load.
[00:49:06] <Jymmm> This is awesome.... HAPPY DANCE https://www.youtube.com/watch?v=LV8d19DRQXM

[02:22:25] <ganzuul> o/
[05:06:15] <XXCoder> heys
[06:13:17] <_methods> Jymmm: hahahah
[06:13:33] <_methods> that emu is awesome
[06:21:16] <XXCoder> today I noticed something odd about my van
[06:21:24] <XXCoder> lights dim each few minutes
[06:21:38] <XXCoder> when waiting for green light it dims while it has rough idle
[06:33:11] <XXCoder> possibly alternator going bad
[07:41:07] <_methods> http://glowforge.com/tech-specs/
[07:41:11] <_methods> ssi:
[07:41:16] <_methods> $4k laser
[07:41:23] <_methods> it's only 40w
[07:41:54] <SpeedEvil> It's got a _really_ cool name though
[07:42:07] <_methods> that helps cut thicker material
[07:42:11] <_methods> lol
[07:43:15] * SpeedEvil keeps pondering making a TEA CO2
[07:43:22] <_methods> 45w for pros
[07:43:33] <_methods> they don't trust the n00bs with that extra 5w of power
[07:59:58] <fenn> you'll put your eye out
[08:00:35] <fenn> someone should make a business retrofitting cheapo chinese lasers to not suck so much
[08:08:34] <Sync> there are already such businesses
[08:08:55] <Sync> they do it by throwing the chinese laser away and putting something proper there
[08:10:16] <fenn> thanks sync, i needed some humor
[08:12:35] <Jymmm> _methods: Yeah, I thought so =)
[08:13:06] <_methods> emu made my day
[08:14:09] <Jymmm> _methods: He should be on http://24hoursofhappy.com/ =)
[08:16:01] <_methods> trade my dog in for an emu
[08:16:02] <_methods> lol
[08:18:18] <Jymmm> Why? You can have BOTH!
[08:20:29] <_methods> damn you're a genius
[08:20:41] <_methods> hey wife i'm gettin an emu
[08:21:26] <Jymmm> There ya go!
[09:33:10] <ssi> _methods: lul
[09:33:42] <ssi> _methods: the only thing noteworthy about the glowforge thing is the stuff they're doing (or purporting to do) with a camera, following a drawing and stuff like that
[09:33:45] <ssi> that's interesting
[09:33:52] <ssi> other than that the maker kids can keep it
[09:46:19] <SpeedEvil> Also actually managing to sell it at a ridiculous price-point.
[09:46:24] <SpeedEvil> Is quite notable.
[09:46:54] <ssi> :P
[09:47:11] <ssi> I think I had about $4k in my 120W 24x48" laser
[09:47:45] <ssi> and that was with mesa hardware and "real" stepper drivers, which adds a fair bit of cost
[09:47:56] <ssi> laser and psu alone was about $1600
[09:48:08] <ssi> the 40W I started with was about $350 for laser and tube
[09:48:13] <ssi> er, tube and psu
[09:49:08] <PetefromTn_> morn
[09:49:13] <ssi> morn pete
[09:49:21] <PetefromTn_> hey ssi
[09:52:12] <ssi> what's shakin
[09:52:40] <PetefromTn_> aah just working on some cnc parts here
[09:53:45] <ssi> excellent
[09:53:56] <ssi> did you see this? https://pbs.twimg.com/media/CRxAOBTUYAA5LG8.jpg:large
[09:54:14] <PetefromTn_> nope
[09:54:19] <PetefromTn_> what is it?
[09:54:24] <ssi> first molded part I cast
[09:54:46] <ssi> I did another pour last night but it was WAY too hot
[09:55:04] <PetefromTn_> looks decent thats pretty cool
[09:55:10] <ssi> yeah I'm pleased
[09:55:33] <SpeedEvil> :)
[09:55:56] <SpeedEvil> What they?
[09:56:10] <PetefromTn_> yeah it looks good
[09:56:10] <ssi> huh?
[09:56:21] <SpeedEvil> ^are
[09:56:43] <ssi> oh, they're trailing links for piper cherokee landing gear
[09:57:34] <PetefromTn_> interesting, I would not have thought aircraft landing gear would be cast aluminum parts
[09:58:26] <SpeedEvil> ah
[09:58:52] <ssi> what would you expect it to be made of
[09:59:28] <_methods> gingerbread
[09:59:45] <PetefromTn_> I dunno billet or something I would think cast porosity dangers would be an issue
[10:00:48] <ssi> the trailing links don't take a hell of a lot of abuse
[10:01:08] <ssi> they exist to keep the wheel pointed straight, but allow it to go up and down via the strut
[10:01:22] <ssi> http://hangarswap.com/image/data/Hangar%20Swap/Flagler/FL0387/IMG_9063.JPG
[10:01:30] <ssi> those are the new style trailing links
[10:01:32] <PetefromTn_> ok I am not familiar with it and you are a lot more experienced with this than I am
[10:01:39] <PetefromTn_> not questioning your methods
[10:01:39] <ssi> the ones I'm casting are the old style, that have an AD on them
[10:01:54] <ssi> they have to be sandblasted and inspected for cracks every 100 hours, which is a huge hassle
[10:02:01] <ssi> so a friend of mine gave me his old set to melt :)
[10:02:11] <ssi> I only used it as a pattern for a test pour, not actually trying to make them
[10:03:15] <ssi> but see, without the trailing links a) the piston would come right out of the cylinder, and b) the wheel would be free to spin in a circle
[10:03:32] <ssi> the trailing links only see sideloading of the gear
[10:03:42] <ssi> and the old AD links would crack around the small pivot
[10:03:47] <ssi> the new ones are way beefier aroun dthere
[10:04:27] <PetefromTn_> those two pivoting links in the second picture look like they would be easy machined parts ;)
[10:04:37] <ssi> they would be fairly easy to machine
[10:04:50] <ssi> but even easier to cast and then finish machine :)
[10:04:53] <ssi> here's another example:
[10:04:54] <ssi> http://melmoth2.com/images/construction/main-lg-struts.jpg
[10:04:59] <ssi> that's the gear off an Arrow, retractable gear
[10:05:03] <ssi> lots of cast parts
[10:05:44] <PetefromTn_> well then you have a bunch of opportunity for having fun with your new forge LOL
[10:05:53] <ssi> yep!
[10:05:59] <ssi> I'm really enjoying it
[10:06:10] <ssi> takes about 12 minutes to melt a crucible load of aluminum
[10:06:15] <ssi> my crucible seems to hold 7-8lb
[10:06:30] <PetefromTn_> thats pretty fast
[10:07:04] <ssi> yeah it is
[10:07:12] <ssi> I ran it too hot last night though
[10:07:21] <ssi> my crucible was actually glowing yellow before the aluminum melted
[10:07:41] <ssi> and when I poured it, I got more burning of the sand than I have in the past, and a really crazy pocked surface finish,
[10:07:47] <PetefromTn_> be careful man! ;)
[10:07:48] <ssi> and the sprue tore away from the part when I separated the flask
[10:08:13] <CaptHindsight> heh, I just had a distributor ask me to open an account with a credit card first before they quote me pricing on a product.
[10:08:21] <ssi> seems legit
[10:08:52] <CaptHindsight> This is the first I've ever seen of this new lunacy. Has anyone ever even heard of this demand from a disti?
[10:09:26] <cradek> smells wrong
[10:09:38] <PetefromTn_> tell em to pack sand
[10:09:44] <CaptHindsight> yeah, nice try
[10:57:17] <PetefromTn_> just broke down an ordered 5 more ER32 short collet holders and 5 collets.....because......well ya just never have enough toolholders LOL
[10:57:24] <ssi> indeed
[10:57:34] <ssi> you still ordering from that same chinese ebay seller?
[10:57:36] <ssi> cme or whatever?
[10:58:05] <PetefromTn_> yup so far so good I am plenty happy with these
[10:58:09] <ssi> yea
[10:58:16] <ssi> I have eight toolholders from them and a set of collets
[10:58:23] <ssi> but naturally I haven't used them at all yet :(
[10:59:11] <PetefromTn_> I notice zero difference between these and the MUCH higher dollar ones I used at the other local shops...both in overall appearance/quality and the amount of cutter compensation adjustment I have been doing
[10:59:23] <ssi> good deal
[11:00:06] <PetefromTn_> I got three more 3/8 collets, two 1/4's and another 1/2 incher
[11:00:15] <ssi> yea
[11:00:29] <ssi> I think I bought a set plus an extra 3/8, 1/2, and 3/4
[11:00:30] <ssi> something like that
[11:00:34] <PetefromTn_> I get tired of swapping between my 3/8 HSS cutter I like for the aluminum and the coated carbide 3/8 all the time LOL
[11:00:40] <ssi> and I have a couple short, medium, long er chucks and a drill chuck
[11:00:58] <PetefromTn_> yeah gotta have a vairety
[11:01:02] <ssi> I want to get a cat40 big facemill
[11:01:10] <ssi> I'd like to have a 4" and a 6"
[11:01:22] <PetefromTn_> I have a bunch of ER20's in short and long and the ER32's are all short
[11:01:24] <ssi> OH SNAP I can cast the toolchanger fingers for the cinci
[11:01:33] <ssi> I have that one broken finger
[11:01:43] <PetefromTn_> I can't imagine needing a 6" facemill for anything I am doing here
[11:02:02] <ssi> man I just want to see that bigass 15hp spindle with a 6" facemill CHEWING UP THE ALUMINUMSSSS
[11:02:03] <PetefromTn_> this 3" Maritool I just got is pretty nice
[11:02:26] <ssi> I have a 3" R8 facemill I use a ton
[11:02:29] <ssi> valenite I think
[11:02:48] <PetefromTn_> even on this steel 6" wide plate I only make two passes because it is actually 3.15 or something
[11:03:03] <PetefromTn_> down and back
[11:03:06] <ssi> yea
[11:04:03] <PetefromTn_> I have some special cutters I have setup that I ONLY use for the picatinny rail program I don't want to ever touch
[11:04:17] <PetefromTn_> so I really have been needing a couple more holders
[11:04:23] <ssi> yeah definitely
[11:04:30] <PetefromTn_> I ordered from him over the phone just now
[11:04:41] <PetefromTn_> he is pretty cool and said I should have them by Friday afternoon
[11:04:47] <ssi> damn that's quick
[11:04:54] <ssi> did you pay for overnight or something?
[11:04:58] <ssi> or 2 day?
[11:05:00] <PetefromTn_> nope
[11:05:04] <ssi> nice
[11:16:05] <skunkworks> http://electronicsam.com/images/KandT/Tooling.JPG
[11:18:07] <ssi> yea yea, rub it in ;)
[11:18:17] <PetefromTn_> show off ;)
[11:19:28] <skunkworks> can't usually buy anymore of those though...
[11:19:41] <ssi> which taper is that?
[11:19:49] <skunkworks> strait shank
[11:19:52] <ssi> ahhh
[11:20:06] <skunkworks> K&T's own design
[11:20:15] <ssi> that's a hassle
[11:20:45] <skunkworks> now that we have the mazak laith - we could probably knock some out if needed.
[11:21:28] <skunkworks> but we got pretty lucky with the selection we got
[11:21:53] <skunkworks> I think there is a bunch in the tool chain too.
[11:21:54] <ssi> I bought some barstock ages ago to try to make some of the goofy hardinge turning toolholders for the HNC
[11:21:58] <ssi> I have a bunch of tooling but more would be nice
[11:22:11] <ssi> now that I can heat treat I can really make some nice ones
[11:23:17] <skunkworks> they come up on ebay every so often
[11:23:31] <ssi> yeah they're expensive tho!
[11:23:53] <ssi> http://www.ebay.com/itm/HARDINGE-CC-15-EXTENSION-TOOL-HOLDER-for-TURRET-LATHE-/380473494002?hash=item5895fcc9f2:m:mteKJQne3IA880-CjExZfsQ
[11:23:59] <ssi> those type
[11:24:22] <ssi> in order to turn anything long, you need long toolholders like that
[11:24:23] <ssi> it's sort of a hassle
[11:24:51] <ssi> http://www.ebay.com/itm/USED-HARDINGE-C16-EXTENSION-LATHE-TOOL-HOLDER/171782526590?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20131003132420%26meid%3D752f528886ef48e9ae048890c68f2b0c%26pid%3D100005%26rk%3D1%26rkt%3D6%26sd%3D380473494002

[11:27:14] <ssi> dammit
[11:27:17] <ssi> heh
[11:34:42] <PetefromTn_> once I get my CNC lathe operational I will be wanting a BUNCH of those aloris style wedge toolpost holders....and some custom ones maybe we can work together and I will machine em and you can harden em for me ;)
[11:34:49] <ssi> lol k
[11:35:22] <PetefromTn_> or not
[11:35:50] <ssi> what?
[11:36:14] <PetefromTn_> I'm kinda serious ;)
[11:36:34] <ssi> yeah that's fine, I'm happy to harden them for you
[11:36:48] <ssi> I can probably do two at a time
[11:36:50] <PetefromTn_> and mebbe I can do something for you in return
[11:37:13] <ssi> aw c'mon man you know I'm not into that
[11:37:27] <PetefromTn_> you're not into getting free CNC milling done?
[11:37:28] <Jymmm> The video proves otherwise.
[11:37:35] <ssi> Jymmm: you can't prove that's me
[11:38:44] <Jymmm> ssi: then you should have never gotten that tattoo on your...um.... yeah you know.
[11:38:52] <ssi> rats
[11:38:55] <ssi> _methods: you around?
[12:06:20] <JT-Shop> ssi, getting closer lol
[12:08:33] <ssi> good!
[12:09:42] <JT-Shop> just have one more thing to sort out and it should be workable, take a look when you get a chance
[12:36:31] <Erant> What do you guys use as a CAM tool? I'm using Fusion360 but it's more than a little unstable, and not always intuitive.
[12:37:00] <JT-Shop> gedit
[12:37:34] <Erant> As in, you write your gcode manually
[12:38:50] <JT-Shop> sometimes, on the lathe I use ngcgui about 95% of the time
[12:39:11] <JT-Shop> I almost have a DXF to G code converter done...
[12:39:38] <Erant> I wish CadQuery had a CAM equivalent, but no.
[12:41:09] <JT-Shop> you looking for 2-d cad or 3-d?
[12:42:08] <Erant> Well, I do my CAD by writing Python with CadQuery.
[12:42:22] <Erant> Mostly 2.5D CAM.
[12:42:52] <ssi> JT-Shop: did anyone ever make and progress on lathe profiling cycles?
[12:42:56] <ssi> like G70/G71 style?
[12:43:15] <Erant> And Fusion360 works reasonably well, but it doesn't like me closing my laptop for example.
[12:43:20] <JT-Shop> not that I know of but I can kinda sorta use ngcgui for that
[12:43:56] <ssi> yea
[12:44:06] <ssi> I need to get my lathe running again :/
[12:44:15] <ssi> I had my minion pull the turret off about an hour ago to check if that seal was in there
[12:44:30] <ssi> I bought a replacement turret seal not long before the fire and I couldn't remember if I put it in the machine or if it got lost in the house
[12:44:36] <ssi> but he seems to think it's in place, so that's good
[12:44:53] <ssi> the only place I know of to get those now is that guy in connecticut that sold me the lathe; he's got them up on backpage still for $50 apiece
[12:46:29] <JT-Shop> what kind of lathe?
[12:46:42] <ssi> HNC
[12:46:54] <JT-Shop> you can get those from McMaster Carr
[12:46:58] <ssi> the turret seal?
[12:47:07] <JT-Shop> I have a handfull of the seals for the turret
[12:47:10] <ssi> the big 8" diameter square seal bastard?
[12:47:15] <JT-Shop> yea
[12:47:19] <ssi> hm cool
[12:47:25] <ssi> what do you call that to find it on mcmaster?
[12:47:53] <CaptHindsight> bastard seals 8 inch, HNC :)
[12:48:17] <JT-Shop> 261n700
[12:48:37] <ssi> that doesn't look up on mcmaster.com
[12:49:19] <JT-Shop> http://www.mcmaster.com/#o-rings/=zgrpo6
[12:50:10] <JT-Shop> that was the number off the bag
[12:50:38] <ssi> hm
[12:50:41] <JT-Shop> email them and they can cross it
[12:50:44] <ssi> yea
[12:52:17] <JT-Shop> I have 4 different X seals in the box, I assume that is the right one lol
[12:52:19] <PetefromTn_> I LIKE those Hardinge lathes... I wish the one I had was a leadscrew model It would probably be CNC by now LOL
[12:52:24] <ssi> ah they're X seals?
[12:52:27] <ssi> I was looking at square seals
[12:55:29] <JT-Shop> X-Profile O-Rings
[12:56:10] <ssi> cool, thanks
[13:00:24] <JT-Shop> http://gnipsel.com/shop/hardinge/images/hardinge-12thm.jpg
[13:00:40] <ssi> that's a teeny picture! :D
[13:00:51] <JT-Shop> http://gnipsel.com/shop/hardinge/hardinge-12.xhtml
[13:01:15] <ssi> man I had the turret body off of mine once, it was not fun
[13:01:25] <ssi> that was when I was trying to figure out why the turret wouldn't run
[13:01:31] <ssi> I had a shuttle valve go bad
[13:01:35] <ssi> $288 to replace
[13:01:49] <ssi> plus one of the air valves in the back compartment had a brazed fitting come out
[13:02:03] <ssi> I think I had all that fixed last time I was messing with it
[13:02:08] <ssi> but that was over a year ago
[13:07:27] <Tom_itx> ssi the trailing links we cut were firs from billet then forged Ti
[13:07:39] <Tom_itx> first*
[13:07:54] <Tom_itx> little bigger plane though
[13:07:57] <ssi> yeah I'm sure :)
[13:08:06] <Tom_itx> citation 10 iirc
[13:08:19] <ssi> buddy of mine is a citation 10 pilot
[13:08:22] <ssi> it's a big bitch
[13:08:42] <Tom_itx> they tried using exhisting forgings but weren't stout enough
[13:09:55] <Tom_itx> still got the iges for it here somewhere
[13:10:40] <Tom_itx> better make sure there aren't any voids in your castings
[13:10:49] <ssi> I'm not casting trailing links for use
[13:10:57] <ssi> that was just a convenient pattern for a test pour
[13:10:58] <Tom_itx> oh, good :)
[13:11:30] <Tom_itx> i would think those would be forgings anyway
[13:11:39] <ssi> they might be, I'm not sure
[13:11:49] <Tom_itx> to control grain direction
[13:22:59] <_methods> ssi: yeah back
[13:29:37] <Wolf_> yah for stripped BHCS...
[13:30:23] <JT-Shop> center punch gets them loose
[13:30:31] <Wolf_> 2 of them are stripped on this renishaw probe
[13:31:41] <Wolf_> only have 3/4” of clearance over the top of them
[13:32:20] <Wolf_> they are in the battery bay on the MP9, the screws that hold the adapter/shank on
[13:33:05] <archivist> just the hex part stripped?
[13:33:12] <Wolf_> yup
[13:33:24] <Wolf_> also really really tight
[13:33:53] <PetefromTn_> renishaw DROOL!!!
[13:34:07] <Wolf_> I dunno if it even works yet
[13:34:18] <archivist> cs stick
[13:35:20] <Wolf_> ?
[13:35:48] <archivist> counsersunk
[13:35:56] <archivist> counter
[13:36:03] <Wolf_> nope
[13:36:37] <archivist> you had BHCS ?
[13:36:56] <archivist> where CS means countersunk to me
[13:40:56] <Wolf_> http://i.imgur.com/YutOwMo.jpg
[13:41:21] <archivist> dome head
[13:41:42] <Wolf_> button head cap screw
[13:42:34] <archivist> also a large contact area relative to size so sticks/shakeproof
[13:43:17] <archivist> punch the head side ways to break that stiction
[13:43:36] <Wolf_> I think its part of the reason for the as it parts only sale lol
[13:44:10] <archivist> also I have sometimes managed to use grips to get them free
[13:44:37] <Wolf_> mount was pretty much stuck, all the centering screws were backed out so I bet they were trying to get it apart
[13:48:24] <Wolf_> contacts are dirty in the probe part i think also
[13:49:08] <andypugh> Drill the heads off anf hope that there is enough shank to grip?
[13:49:26] <ssi> buttonheads don't work well like that
[13:49:32] <ssi> when you drill the head off there's nothing left
[13:49:46] <Wolf_> can’t drill the heads off
[13:49:49] <ssi> screw extractor might work ok
[13:50:01] <Wolf_> solid mass of probe body in the way
[13:50:04] <archivist> in a recess
[13:50:26] <andypugh> ssi: How much is left depends on how thick the clamped part is, and not a lot else.
[13:50:49] <Wolf_> 3mm or so
[13:50:49] <andypugh> A screw extractor will probably only serve to end all hope.
[13:51:14] <andypugh> (though I have proved that you can mill screw extractors with a carbide end-mill)
[13:51:21] <ssi> also depends on if you can remove the clamped part once the head is gone
[13:51:28] <ssi> if it's concentric parts, you won't be able to
[13:52:15] <archivist> the hard way is dremel grind heads off, drill threads out after disassembly
[13:53:35] <Wolf_> I’ll give the center punch a go first, that half is sorta minor right now anyways
[13:54:30] <Wolf_> probe is showing open circuit on Ω test
[13:54:38] <Wolf_> unless I pull on it
[13:55:58] <Wolf_> so I’m guessing the contacts are dirty in it
[13:56:10] <archivist> my valeron probe was like that until I cleaned the contacts
[13:56:57] <Wolf_> looks like 4 set screws then the end of the housing unscrews
[14:06:59] <FinboySlick> Wolf_ If desperate with those screws, careful use of hacksaw might get you enough of a flathead to remove it.
[14:07:09] <FinboySlick> I know I've had to resort to that once or twice.
[14:07:45] <FinboySlick> If you can match the slot well enough (to minimize chances of stripping that too) you might get half decent leverage too.
[14:08:10] <SpeedEvil> slitting disk on a dremel works well too
[14:09:11] <andypugh> Cut through the probe body and the screw with a slitting disc. You will damage the body, but it will still work.
[14:09:28] <andypugh> (and you may be able to re-machine the faces anyway)
[14:10:16] <andypugh> Wolf_: Which probe model?
[14:11:22] <Wolf_> Mp9
[14:11:36] <andypugh> I have an MP3
[14:11:54] <andypugh> I _think_ I found service kit installation instructions on the internet
[14:12:14] <FinboySlick> ssi: Just saw the casting pic... Is it aluminium shrinkage on the fat part? Doesn't seem as round/wide.
[14:12:29] <Wolf_> I kinda want to not destroy the optical body, I also got a older OMM off eBay :D
[14:13:18] <ssi> FinboySlick: I think it's a perspective thing
[14:13:29] <ssi> I haven't actually measured to compare dimensions but visually they're pretty close
[14:13:29] <archivist> and an mi4?
[14:14:04] <FinboySlick> ssi: Is the pitting from bubbles or sand?
[14:14:09] <Wolf_> thats next, I wanted to spin the mp9 to make sure the output works before spending the $$
[14:14:09] <CaptHindsight> ssi: what material was used for the pattern to make the sand mold?
[14:14:14] <FinboySlick> (I'm pretty interested in casting too)
[14:14:24] <ssi> FinboySlick: little of both... I need a deeper sprue so some of the dross gets captured
[14:14:36] <ssi> mostly sand though
[14:14:41] <ssi> CaptHindsight: aluminum
[14:14:51] <ssi> I used the part on the left as the pattern for the part on the right
[14:14:55] <ssi> just a a test
[14:15:08] <andypugh> Wolf_: Not this one? http://resources.renishaw.com/download/leaflet-olp40-rlp40-eyelid-service-kit--30569
[14:15:10] <ssi> sand was a bit too dry, and the heavy pattern fell out when I flipped it, and some of the edges broke
[14:15:14] <ssi> that's why there's such bad flash
[14:15:24] <CaptHindsight> ssi: what did you use for sand?
[14:15:25] <FinboySlick> It's pretty cool that you can see the tape in the casting.
[14:15:30] <ssi> homemade greensand
[14:16:05] <Wolf_> andypugh: nope
[14:16:23] <andypugh> It looks like my MP9
[14:16:25] <CaptHindsight> I'm going to make and easy to use green sand with a heat set binder
[14:16:35] <andypugh> Which means that you don’t start at that end :-)
[14:16:40] <ssi> I ordered some sodium silicate off amazon for cores
[14:16:45] <ssi> I need to get a co2 bottle from the welding store
[14:17:02] <Wolf_> andypugh: http://www.ebay.com/itm/111779639915
[14:17:06] <andypugh> Taje off the other end cover (two screws) then carry on from there
[14:17:07] <FinboySlick> You guys aware of anyone using an induction heater to make iron casting?
[14:17:21] <ssi> I'm gonna try to build a better furnace to do iron in eventually
[14:17:25] <FinboySlick> (backyard-type, not a pro outfit, obviously)
[14:17:52] <CaptHindsight> green sand with binder for hand casting with a pattern or with an inkjet to print binder into the sand for pattern-less applications
[14:18:14] <andypugh> Wolf_: Yes, the three screws in the counterbores, then the end cover, then some rubber bellows, and you will find the probe parts in there. The back is all potted up solid
[14:19:10] <ssi> my greensand is home depot play sand mixed with 10% by weight bentonite clay
[14:19:14] <ssi> wetted to consistency
[14:20:56] <FinboySlick> I guess I got my answer: https://www.youtube.com/watch?v=OJGaQdgPRmA
[14:22:05] <archivist> I want to get inside the TP2 probe one day to clean the contacts
[14:22:10] <andypugh> Wolf_: As for the button-heads, try Vise-grips.
[14:22:50] <andypugh> FinboySlick: That seems pretty keen
[14:23:09] <archivist> worth grinding the jaws to get a close grip
[14:23:31] <FinboySlick> andypugh: It's pretty cool that the whole furnace can tilt.
[14:23:49] <Wolf_> probe shouldn’t be oil filled right?
[14:26:10] <andypugh> FinboySlick: http://webpages.charter.net/dawill/tmoranwms/Elec_IndHeat1.html (But nowadays I would be doing all the sequencing and tuning with an Arduino, rather than alalog elecronics). http://webpages.charter.net/dawill/tmoranwms/Elec_IndHeat1.html
[14:27:36] <Wolf_> because this probe is totally filled with oil lol
[14:29:29] <PCW> wouldn't it be a lot better to make a probe with cheap accelerometers nowadays and just use the balls/rods as a repeatable mechancal stop?
[14:30:20] <PCW> (they could be ruby or something else more wear resistant)
[14:30:21] <archivist> cheap strain gauges
[14:30:36] <FinboySlick> pcw: Care to expand on how you'd design a probe with accelerometers?
[14:30:50] <FinboySlick> You'd just measure the tilt?
[14:30:53] <PCW> I was thinking of differential accelerometers
[14:31:15] <archivist> some now have a piezo element to "hear" the contact too
[14:31:51] <PCW> Yeah, high frequency burst when hit
[14:32:50] <PCW> I saw Dabits probe on the forum that looks really nice but contacts seem like the wave of the past
[14:33:04] <archivist> hmm fpga card could be used for my LVDT probe
[14:33:42] <Wolf_> umm wtf http://i.imgur.com/eu4PY6S.jpg
[14:34:13] <andypugh> OK, so someone on the forum pulled off and destroyed his commutation encoders. Please tell me that I am not being stupid to suggest that eBay resolvers might be a good replacement?
[14:35:08] <andypugh> Wolf_: I don’t thnk it is _meant_ to be filled with oil. But perhaps it is?
[14:35:14] <archivist> Wolf_, some probes have an outer seal assembly before you get into the contacts
[14:35:27] <PCW> When (a million years ago) I was making resilient modulus measuring equipment we had these probes the resolved something around 1 uinch
[14:36:01] <archivist> smaller than a gnats cock
[14:36:02] <andypugh> Wolf_: If (big “if”) your probe is like mine you can now take off the 6 screws and lif out the three-legged thng.
[14:36:06] <Wolf_> I can see the contact bars
[14:36:57] <andypugh> The balls are captive on the ring and contact is by springs. All surprisingly non-fiddly.
[14:37:22] <andypugh> But beware of http://www.urbandictionary.com/define.php?term=Pingfukkit
[14:38:19] <archivist> I have heard those hit something behind me out of sight
[14:39:39] <andypugh> PCW: Contact may be old-school but the probes work incredibly well. Wheels strike me as very old school too, but seem to work :-)
[14:40:03] <PCW> :-)
[14:41:26] <PCW> I guess I was just responding to all the fancy things DaBit was doing, worrying about EDM-ing the contacts etc
[14:41:28] <archivist> one nice thing about the contact type is the over travel they can sustain
[14:41:47] <andypugh> Are the Ali-express ads tagetted? They seem to be trying to sell me sexy (ladies) underwear. I am the least likely person in the world to buy that. So what makes them want to advertise them to me? The only things I have ever looked at on their actual site is gear hobs and servo motors.
[14:42:38] <PCW> yes you still need that or a similar mechanism to allow both over-travel and quick settling after overtravel
[14:42:56] <Wolf_> ok, probe is now dismembered, what to clean it with...
[14:43:03] <PCW> (they just dont need to be contacts)
[14:43:35] <Roguish> the 'balls and rods' can work really good. http://www.precisionballs.com/
[14:43:43] <archivist> kinematic mount just for safety
[14:44:49] <Roguish> http://www.precisionballs.com/Kinematics_Components_Catalog_105B.php#graphical
[14:46:44] <PetefromTn_> that looks like a great place to get your balls! ;)
[14:47:44] <Roguish> ya want fine adjustments? how about 100 tpi or better ....... http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1208
[14:48:41] <andypugh> Roguish: Differential screws are probably a better idea
[14:48:54] <andypugh> And easy to make with CNC.
[14:49:43] <PetefromTn_> I would love for you guys to tell me how I can make a probe that is anywhere close to a renishaw here in the shop for dinero pequeno
[14:49:50] <Roguish> those will work also, but are 2 piece. I know of some 200 tpi adjusters. imaging the taps....
[14:50:07] <andypugh> https://en.wikipedia.org/wiki/Differential_screw
[14:50:44] <andypugh> PetefromTn_: You might as well get a real Renishaw from eBay. It’s probably cheaper. I paid £50 for my “Renshaw"
[14:51:13] <archivist> I would like to measure one of those threads to see how well they get the pitch
[14:51:19] <PetefromTn_> is that some chinese wack off of a real renishaw?
[14:51:33] <jdh> anyone ever used modbus tcp with an anybus chip?
[14:51:36] <andypugh> PetefromTn_: No, an eBay vendor who couldn’t spell :-)
[14:51:43] <PetefromTn_> aah
[14:51:47] <PetefromTn_> love those
[14:52:00] <Roguish> i've used the 100 tpi. the threads feel and look like scratches, but they actually work.
[14:52:30] <Wolf_> I’ll be $195 in to this renishaw setup after I order the Mi4 box
[14:53:22] <andypugh> There is a “Renshaw” probe here, but sadly it is priced as a Renishaw: http://www.ebay.com/itm/RENSHAW-TS27R-TOOL-SETTING-PROBE-/301774075957?hash=item464322f835:g:RzIAAOSw9mFWJ3QT
[14:56:24] <Roguish> speaking of probes, how is this one? of any value? http://www.cadcamcadcam.com/contactprobe.aspx
[14:56:57] <Roguish> not a Renishaw, but worth the price???
[14:57:32] <andypugh> I would rather pay 20% of the price for a real Renishaw
[14:57:42] <_methods> pretty bold callin it a tp-100
[14:57:50] <PetefromTn_> that is the table mounted tool probe..
[14:57:58] <_methods> looks like it uses standard renishaw stylus too
[14:57:59] <PetefromTn_> works excellent in my experience
[14:58:35] <_methods> i'm suprised they haven't shut that down
[14:59:06] <wolfmanjm> anyone know if there is a arduino sketch that just does pass through of parallel port signals to say a ramps board? basically I'm thinking the arduino would simply monitor the step/dir signals and mirror them to the stepper drivers on a ramps (or equivalent) board
[15:00:01] <wolfmanjm> I have several arduino based boards with stepper drivers on them and it would be cool to have them work with linuxcnc basically just using them as external stepper drivers.
[15:00:54] <andypugh> wolfmanjm: One solution would be to run LinuxCNC on a Udoo, as that has an Arduino pinout.
[15:01:22] <_methods> https://ckcnc.wordpress.com/basic-arduino-emc-howto/
[15:01:25] <wolfmanjm> yea but i already have LinxCNC running on an old PC
[15:01:27] <_methods> or maybe google
[15:01:42] <wolfmanjm> tried google ;) I will write it if it has not already been done
[15:01:49] <_methods> https://ckcnc.wordpress.com/basic-arduino-emc-howto/
[15:01:50] <_methods> https://ckcnc.wordpress.com/basic-arduino-emc-howto/
[15:01:52] <_methods> https://ckcnc.wordpress.com/basic-arduino-emc-howto/
[15:02:18] <FinboySlick> The thing I regret most about my mill (aside for its non-cartesian nature) is the lack of repeatable tool holders. Having to mess with the collet nut every tool change is a lot more hassle that I had anticipated.
[15:02:30] <archivist> wolfmanjm, you want the arrrrrghino just to emulate a stepper driver (step dir in)
[15:03:15] <FinboySlick> It also makes use of a probe pretty difficult. Heck, finding an edge finder that fits ER11 is tricky enough.
[15:03:20] <wolfmanjm> no not really, it is simper than that and the post _methods posted is not what I am thinking of
[15:04:40] <wolfmanjm> I have an Azteeg X3 PRO, runnign grbl at the moment. But I'm thinking with a very simple sketch running on it I can hook up the parallel port lines to the spare pins, and simply pass through the step/dir signals to the pins that teh drviers are conencted to. so linuxcnc still does all the timing and stuff
[15:04:53] <PetefromTn_> FinboySlick I hear ya but I would think a plate tool probe macro would help considerably
[15:05:30] <Wolf_> hmmm Milling machine-van norman ram type horizontal/verticle $500 think i may go look at that tomorrow
[15:05:41] <_methods> nice
[15:05:48] <_methods> those van normans are good machines
[15:05:50] <PetefromTn_> probably a VERY HEAVY machine
[15:06:01] <_methods> pain in the butt switching from horizontal to vertical
[15:06:07] <Wolf_> been on cragslist for 2-3 months now
[15:06:07] <PetefromTn_> but they are beasts when it comes to cutting metal
[15:06:08] <_methods> but nice to have the flexibility
[15:07:21] <andypugh> FinboySlick: Are there any quick-change adaptors for ER11?
[15:07:40] <andypugh> (Maybe not, that’s pretty tiny)
[15:08:31] <FinboySlick> andypugh: Not that I could find. It's machined straight into the spindle motor shaft (think router) so that would have to be drilled to slide in a drawbar.
[15:08:35] <andypugh> FinboySlick: If you have a lathe you could make a bunch of solid ER11 “collets” with tools held in by setscrews. At least then you have repeatable length.
[15:08:36] <Praesmeodymium> well son of a bitch my motors from newegg were delivered to day.... to somewhere else. need to file a refund request, shipped motors intended for opregon to georgia
[15:08:40] <archivist> andypugh, I have seen end mills having the shaft tapered to fir ER series
[15:08:45] <archivist> fit
[15:08:48] <Wolf_> any suggestions on what to wash this oil out of the probe body?
[15:09:08] <malcom2073_> mineral spirits? Unknown if that would hurt the electronics
[15:09:35] <andypugh> Wolf_: I think I would use White Spirit.
[15:09:42] <PetefromTn_> probably some denatured alcohol or similar
[15:09:43] <archivist> I use spirits and the ultrasonic tank
[15:09:43] * JT-Shop is being attacked by ladybugs
[15:09:54] <Wolf_> Praesmeodymium: mine showed delivered to Calf from china, but one of the packs showed up with usa ship from address
[15:10:38] <malcom2073_> Praesmeodymium: Mine said the same thing, I emailed them, they sent me a "corrected" tracking number
[15:10:45] <andypugh> malcom2073_: Having checked Wikipedia, I see that “Mineral Spirits” is USA-ian for White Spirit.
[15:10:53] <malcom2073_> Seems the china tracking number is no good in the usa heh
[15:10:55] <malcom2073_> andypugh: Nice
[15:11:13] <andypugh> Also reasonably good as a fire-breathing liquid.
[15:11:15] <malcom2073_> So I have a USPS tracking number
[15:11:33] <Wolf_> oh cook I think I can pull the upper contact plate out as well
[15:11:48] <Wolf_> cook/cool
[15:12:01] <FinboySlick> Haha, wow: http://www.joinersales.com/wp-content/gallery/400__bottom/VAN%20NORMAN%20UNIVERSAL%20MILL.JPG Now there's a van-norman.
[15:12:48] <andypugh> FinboySlick: One word that does not come to mind is “Flimsy”
[15:13:02] <_methods> i would use acetone mineral spirits can leave residue
[15:13:17] <malcom2073_> Mmmm them box ways
[15:13:23] <andypugh> But Acetone dissolves some plastics
[15:13:33] <_methods> yeah
[15:13:36] <_methods> this is true
[15:13:57] <FinboySlick> andypugh: Don't know if it's the paint job but it looks pretty darn well maintained too.
[15:14:04] <andypugh> I have never known White Spirit to damage anything, I use it to de-gunk my motorcycle.
[15:14:22] <_methods> contact cleaner
[15:14:30] <PetefromTn_> by white spirit you mean God?
[15:14:36] <PetefromTn_> ;)
[15:14:43] <andypugh> FinboySlick: Top spindle speed is likely to be 1000 rpm....
[15:14:45] <FinboySlick> andypugh: The thought of moving it made me think of your engine hoist picture.
[15:14:45] <_methods> why is there oil in the probe?
[15:15:05] <PetefromTn_> makes the trons flow better :D
[15:15:12] <_methods> lol
[15:15:58] <andypugh> FinboySlick: That photo is Photoshopped, look at the telegraph pole :-)
[15:16:35] <malcom2073_> andypugh: Look behind the pallet leaning on the fence
[15:16:41] <malcom2073_> Between the slats
[15:16:42] <PetefromTn_> http://www.ebay.com/itm/200W-CNC-Digital-AC-Servo-Driver-and-AC-Servo-Brushless-Motor-3000rpm-0-64N-m-Y-/151332115504?hash=item233c18d430:g:QrAAAOSw-nZTorRQ ??
[15:19:07] <andypugh> (I was joking, in case you believed I believed that)
[15:21:03] <Jymmm> andypugh lies, and photoshopped that himself!
[15:21:54] <XXCoder> nah it is real photo. Jymmm andypugh broke in factory and took pic there himself
[15:22:07] <Jymmm> XXCoder: Ah, gotcha
[15:22:14] <FinboySlick> PetefromTn_: I'll take 5
[15:23:51] <Praesmeodymium> malcom2073_: I sent an email we will see, I can hope I got the wrong number I dont think i can replace the 5 motors for that cheap ever again lol
[15:24:11] <Jymmm> cradek: https://vimeo.com/26607676
[15:24:48] <malcom2073_> Though, it's been 5 days since theUSPS "Accepted" the package
[15:24:50] <malcom2073_> and it's 3 day delivery
[15:24:52] <malcom2073_> so... I dunno
[15:24:59] <malcom2073_> I did get 4 from this seller, so they're semi-legit
[15:25:10] <malcom2073_> could be they just suck at shipping from china, the ones I got previously came from their warehouse in NJ
[15:25:18] <PetefromTn_> you'll take 5 what??
[15:25:25] <XXCoder> hyperdrives
[15:25:30] <FinboySlick> PetefromTn_: Of those motors.
[15:25:33] <XXCoder> real cheap steppers if I recall
[15:25:44] <PetefromTn_> says servos..
[15:25:50] <PetefromTn_> probably hybrids
[15:26:06] <PetefromTn_> I need two in a 750watt flavor
[15:26:26] <XXCoder> if I recall it was pretty nice motors and drivers for 9 bucks
[15:26:39] <FinboySlick> PetefromTn_: Oh, you think they're more like 'stepper with encoder' type of deal?
[15:26:40] <XXCoder> nema23 was thin and cheap but drivers was worth way more
[15:27:19] <PetefromTn_> dunno thats why I put ??
[15:27:29] <PetefromTn_> it SAYS AC servo drive
[15:28:59] <PetefromTn_> http://www.ebay.com/itm/0-75kw-750W-AC-servo-motor-drive-set-1PH-220V-2-4NM-modbus-2500ppr-CNC-new/201344944375?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D777000%26algo%3DABA.MBE%26ao%3D1%26asc%3D33873%26meid%3D519c7b5e5c044eea9f58263267eb7233%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D151791787971 these look nice but CHINA
[15:29:20] <andypugh> PetefromTn_: 3-phase output looks like servo to me
[15:30:27] <PetefromTn_> I thought steppers were technically 3 phase?
[15:30:47] <andypugh> No, 2 phase or (sometimes) 5 phase
[15:31:12] <ssi> steppers are 2 phase, 50 pole brushless motors
[15:32:12] <PCW> There are 3 phase stepmotors
[15:32:36] <PCW> (Tormach uses them for example)
[15:32:59] <PCW> not sure what the step size is
[15:33:38] <ssi> PetefromTn_: those chinese servos/drives would be worth trying if the shipping weren't so prohibitive
[15:34:00] <andypugh> Add the shipping to the price and it still looks good.
[15:34:19] <PetefromTn_> I wonder if they combine shipping on em?
[15:34:33] <ssi> yea if you could get three of them shipped for about $1200 that'd be alright
[15:34:44] <PetefromTn_> I mean honestly the TEco's I have running my VMC are chinese and I have had great luck with them
[15:34:46] <ssi> 2500ppr encoders
[15:34:57] <ssi> well there's chinese and then there's chinese :)
[15:35:08] <PetefromTn_> I know thats the trouble here
[15:35:56] <ssi> here you go

[15:36:00] <ssi> pay more, free shipping
[15:36:04] <ssi> better deal overall if they won't combine
[15:36:57] <PetefromTn_> yeah that is what the going rate is....just have trouble buying from someone in CHINA named Fastobuy LOL
[15:37:24] <XXCoder> fast to buy
[15:37:42] <andypugh> And he has been around since 2012!
[15:37:43] <XXCoder> same picture as other one
[15:38:16] <XXCoder> "Member since: Nov 19, 2012"
[15:38:53] <FinboySlick> ssi: I really like the picture called: "C:\Users\Administrator\Desktop\..."
[15:39:13] <ssi> lul
[15:39:26] <ssi> I want to find some servos about that size with encoders and cables, but no drive
[15:39:39] <ssi> I got my stmbl boards today, gonna hopefully get one assembled in the next day or so
[15:40:40] <andypugh> It seems I have been on eBay since 2000 !
[15:40:46] <PetefromTn_> woohoo just sold two more rails!!
[15:41:52] <XXCoder> andypugh: "Member since: Jan 05, 1998"
[15:41:56] <XXCoder> thats my account
[15:42:23] <SpeedEvil> I was a member since before they launched in the UK.
[15:42:33] <SpeedEvil> (my account is still a bit fucked)
[15:42:51] <SpeedEvil> (they send me notifications from the US site - in dollars, with links to .com)
[15:44:53] <FinboySlick> Hmmm... http://www.ebay.com/itm/12000rpm-8KW-380V-18A-400Hz-Air-cooled-ATC-Spindle-Motor-ISO9001-2000-NEW-/111704027468 "Repair time: bearing(half year),spindle(one year). I wonder what that means.
[15:45:05] <FinboySlick> You have to change the bearings every 6 months?
[15:45:21] <XXCoder> or maitance like grease? dunno
[15:45:24] <_methods> party at PetefromTn_'s house
[15:45:28] <Connor> 9 minutes till Marty Arvies.
[15:45:47] <PetefromTn_> woohoo party on boys!!
[15:46:01] <FinboySlick> Marty arrives, blackbagged by DHS.
[15:46:07] <XXCoder> http://istodaythedaymartymcflyarriveswhenhetravelstothefuture.com/
[15:46:14] <PetefromTn_> who's Marty?
[15:46:22] <Connor> PetefromTn_: Back to the Future.
[15:46:27] <XXCoder> You dont know who Marty McFly is??
[15:46:28] <FinboySlick> PetefromTn_: Today is when Marty from back to the Future arrives.
[15:46:30] <PetefromTn_> oh yeah doh
[15:46:41] <Connor> Well.. Wait.. It's PST
[15:46:44] <Connor> not East coast..
[15:46:45] <Connor> damn
[15:46:50] <FinboySlick> He'll be sad to find that his floaty-skateboard needs a special track.
[15:46:52] <Akex_> Lol Connor ;)
[15:47:03] <PetefromTn_> so he's already here then?
[15:47:19] <XXCoder> not for few hours
[15:47:23] <Connor> No. 4 hours and change
[15:47:32] <XXCoder> 3 hours
[15:47:34] <PetefromTn_> LOL that's cool
[15:47:37] <XXCoder> 1:23 pm here
[15:47:44] <PetefromTn_> jeez I'm old
[15:48:04] <FinboySlick> PetefromTn_: But not obsolete.
[15:48:17] <Connor> They never talked about what time zone the DeLorean was set too...
[15:48:21] <FinboySlick> (Terminator Genesis reference)
[15:48:26] <PetefromTn_> you know when a movie you watched as a kid shows a far in the future date for "the FUTURE" and now your're there...well you'd be OLD
[15:48:27] <XXCoder> Connor: but we know where he arrives
[15:48:30] <XXCoder> calfornia
[15:48:35] <XXCoder> so yeah lol
[15:49:10] <FinboySlick> PetefromTn_: Well, you're older if you weren't a kid when it came out.
[15:49:16] <ssi> I find it hard to believe that doc would design his time circuits around anything other than UTC ;)
[15:49:18] <FinboySlick> So look on the bright side.
[15:49:22] <PetefromTn_> I tried to call Arturo Duncan three times today about servos and never got him LOL
[15:49:28] <XXCoder> http://www.october212015.com/
[15:49:35] <XXCoder> soon exactly 3 hours
[15:49:45] <ssi> PetefromTn_: ?
[15:50:04] <PetefromTn_> ?
[15:50:08] <Connor> I liked when Fox showed Buck Rogers (in syndication) they intro always stated the year he left Earth.. they would always advance the year by 1 year when it was show.. to keep it "in date"
[15:50:50] <XXCoder> why why is there billion 43 mm spindle holders but zero spindle that diameter
[16:10:29] <SpeedEvil> https://www.youtube.com/watch?v=Pw8T1YgnVck - inconel machining.
[16:10:33] <SpeedEvil> Wow
[16:13:20] <Connor> XXCoder: Is that for a Kress ?
[16:13:39] <XXCoder> Connor: the chinese 4030 cnc router
[16:13:51] <Connor> Yea.. but the holder is for a Kress Spindle..
[16:13:55] <Connor> which is 43mm
[16:14:19] <XXCoder> I need to check mount holes it might have one larger set for 53 mm
[16:14:28] <XXCoder> it do have 6 holes and use only 2
[16:14:37] <XXCoder> Connor: oh yea! that expensive router
[16:15:08] <XXCoder> aw mythbusters is ending
[16:15:18] <Connor> do what?
[16:15:20] <PetefromTn_> nice ceramics!!
[16:15:22] <XXCoder> with a bang though not just sudden end
[16:15:48] <XXCoder> http://www.ew.com/article/2015/10/21/mythbusters-ending-interview
[16:17:03] <Connor> That sucks. Kinda saw that happening after they got rid of Grant, Kari and Tory
[16:17:21] <XXCoder> yeah its been long years
[16:17:24] <XXCoder> 14 years.
[16:17:46] <XXCoder> enough for them to look youngish to mid
[16:18:14] <Wolf_> http://i.imgur.com/X1ozLpw.jpg
[16:18:19] <Wolf_> :D
[16:18:54] <XXCoder> YOU BROKE IT!!
[16:18:54] <XXCoder> heh
[16:19:29] <Connor> Wow, so that's what's in a Renishaw passive..
[16:19:53] <Connor> How do you adjust those ?
[16:21:53] <Connor> Someone made a 5 contact instead of a 3 contact version...
[16:21:58] <Connor> not sure what that gets you..
[16:24:13] <XXCoder> glowforge needs internet to work
[16:24:14] <XXCoder> jeez
[16:24:32] <XXCoder> how long before someone hacks it
[16:24:36] <Connor> Why ?
[16:25:18] <XXCoder> http://www.tested.com/tech/548192-going-depth-glowforge-laser-cutter/ reading
[16:31:08] <XXCoder> they said they will allow people to0 flash custom firmware but it will void warranty. not too bad considering if they go under in 5 years can flash new firmware and use it without cloud
[16:35:43] <Wolf_> Connor: adjustments are at the mounting/adapter area
[16:37:19] <Wolf_> nothing fancy either, just 4 screws
[16:44:08] <Deejay> gn8
[17:02:08] <Connor> Here is the one I was talking about that is 5 way vs 3 way
[17:02:08] <Connor> http://www.ebay.com/itm/Stainless-CNC-Digitizing-Touch-Probe-Toolsetter-3-8-adj-for-Mach3-Sherline-Taig-/131613972270?hash=item1ea4cdd72e:g:WcEAAOSw0vBUg2lI
[17:27:08] <Roguish> andypugh: see here. look at lower right adjustment screw.................. http://www.thorlabs.com/navigation.cfm?guide_id=131
[17:36:09] <MacGalempsy> hola
[17:37:43] <malcom2073_> Hi
[17:42:27] <JT-Shop> dang this dxf2gcode is fast
[17:42:38] <JT-Shop> still wrong but real fast
[17:46:03] <Tom_itx> hah
[17:46:27] <Tom_itx> JT-Shop, is 'go' a compiled language?
[17:46:29] <JT-Shop> but getting close
[17:46:31] <Tom_itx> or interpreted
[17:46:31] <JT-Shop> yes
[17:46:46] <Tom_itx> like c?
[17:47:26] <JT-Shop> beats me lol
[17:47:43] <JT-Shop> I thought c was compiled...
[17:47:50] <Tom_itx> it is
[17:48:07] <Tom_itx> basic was interpreted
[17:48:17] <Tom_itx> one that comes to mind...
[17:48:40] <andypugh> Python is interpreted
[17:48:57] <andypugh> (or, possibly, compiled on-demand)
[17:49:12] <Tom_itx> still slower
[17:49:43] <Tom_itx> but there's not much to the converter he wrote as far as overhead
[17:49:58] <Connor> andypugh: python can be both
[17:55:06] <JT-Shop> almost got it sorted out... the sorting of the entities is the fun part lol
[17:57:47] <JT-Shop> it's down to a matter of a few offsets that are backwards now :)
[17:58:08] <Tom_itx> no biggie...
[17:59:23] <JT-Shop> yea, I just need more smarts in my switch
[18:10:37] <JT-Shop> one less error...almost there
[18:24:03] <Sync> bah
[18:24:20] <Sync> those philips scales use a goddamn trick circuit
[18:24:55] <PetefromTn_> well finally got ahold of Arturo Duncan at CNC4PC this afternoon
[18:25:32] <Tom_itx> about what?
[18:25:34] <PetefromTn_> he is supposed to be giving me a GOOD price on two axes worth of the DMM servo motor/drivers/cabling tomorrrow...crossing fingers
[18:25:54] <Tom_itx> 700w?
[18:25:56] <PetefromTn_> hopefully I can swing it and go ahead and order them
[18:25:58] <PetefromTn_> 750
[18:26:22] <PetefromTn_> can't wait to start building this BEOTCH
[18:26:32] <Tom_itx> better than automation direct?
[18:26:48] <jdh> I spent a couple hours writing some code to speak modbus tcp to a flow meter. The manual said modbus registers 40001-40065. Tried that, tried 0, 1, turns out that it really starts at 513.
[18:26:50] <Tom_itx> or whatever it's called now
[18:26:51] <PetefromTn_> I tried automation direct and their drives are kinda funky..
[18:27:04] <PetefromTn_> they also require a seperate power supply
[18:27:10] <PetefromTn_> and some other module
[18:27:20] <Tom_itx> and the ones you're looking at?
[18:27:30] <PetefromTn_> these DMM servos are basically designed to work just like my TEco's
[18:27:53] <PetefromTn_> yeah built in power setup wired for 110 or 220vac
[18:28:07] <PetefromTn_> just wire em up and hook up the premade cables for motor and encoders
[18:28:28] <PetefromTn_> wire up the high density connection to linuxCNC7i77 card and you are good to go
[18:28:42] <PetefromTn_> basically just like the Cincinatti Arrow 500 build here
[18:30:49] <PetefromTn_> I am also looking at that Hitachi WJ200-110lf drive like I am using for the Cincinatt for the spindle but I have not bought it yet because I am trying to find information about the one that Zeeshan used for his mill and other similar chinese drives
[18:32:23] <Sync> or get our drive and hope we get async vectoring running quickly :D
[18:32:38] <Tom_itx> direct 110/220 would be handy
[18:32:59] <PetefromTn_> you mean that DIY drive?
[18:34:01] <Sync> yes
[18:34:56] <PetefromTn_> I would definitely consider it but ssi made it sound like it was a ways off and required a good bit of programming knowledge if you are new here you will realize that I SUCK at that part LOL
[18:35:25] <Sync> well, it is not really ways off
[18:36:02] <Sync> but we currently only can do motors with some kind of feedback device
[18:36:41] <PetefromTn_> what do you mean?
[18:37:13] <Tom_itx> closed loop
[18:37:27] <PetefromTn_> oh I would not have it any other way ;)
[18:38:06] <Sync> well the nextgen™®© hardware can do async vector control
[18:38:09] <Sync> without feedback device
[18:38:42] <PetefromTn_> all I need is analog 0-10v closed loop control with reasonable encoders
[18:39:05] <Sync> 0-10V is not happening
[18:39:05] <Tom_itx> +-10
[18:39:31] <PetefromTn_> yeah sorry +/-10v
[18:39:39] <Sync> that's still not happening :D
[18:39:45] <Tom_itx> my sherline is 0-10
[18:39:46] <PetefromTn_> why?
[18:40:00] <PetefromTn_> how do you plan to control the motors?
[18:40:09] <Tom_itx> pwm probably
[18:40:22] <Sync> quadrature or direct velocity/position commands
[18:41:30] <Sync> well, what is a reasonable encoder for you?
[18:42:06] <PetefromTn_> whatever is typical I think mine are 2500 or somthing like that
[18:42:08] <Sync> we can do quadrature, resolvers, sin/cos and about all digital absolute things
[18:42:18] <Sync> yeah quadrature is not an issue
[18:42:53] <Tom_itx> Sync, who is this 'we' you speak of?
[18:44:20] <Tom_itx> not familiar with what you're developing
[18:44:21] <Sync> me and two other guys
[18:44:59] <Sync> https://github.com/rene-dev/stmbl
[18:47:27] <Tom_itx> mmm i got one of those
[18:47:29] <Tom_itx> boards
[18:48:16] <Tom_itx> never bothered to learn to program arm though
[18:49:51] <Tom_itx> those are all 3.3v ip aren't they?
[18:50:31] <Tom_itx> io
[18:50:35] <PetefromTn_> tryin to buy my wife something on Amazon and they are offering a free shipping trial 2 months of amazon prime?
[18:51:10] <_methods> i buy so much off amazon prime is a no brainer
[18:51:23] <_methods> only reason i go to a real store anymore is for groceries
[18:51:25] <PetefromTn_> what is?
[18:51:42] <_methods> amazon prime
[18:51:44] <PetefromTn_> I almost buy everything from ebay
[18:51:53] <_methods> i get a lot from there too
[18:52:02] <PetefromTn_> never use amazon
[18:52:06] <Tom_itx> _methods, amazon thanks you
[18:52:09] <PetefromTn_> whats the deal?
[18:52:19] <_methods> it's easy?
[18:52:24] <_methods> and i don't have to leave the house
[18:52:48] <PetefromTn_> no I mean what is prime and whats it gonna cost me?
[18:52:53] <Sync> Tom_itx: not all of the ios are 5V intolerant ;)
[18:53:02] <_methods> oh it's mainly free shipping
[18:53:08] <_methods> but they have shitty music and lame movies
[18:53:32] <Tom_itx> all the more reason..
[18:55:28] <_methods> free 2 day shipping is the big thing
[18:55:46] <PetefromTn_> yeah but whats it cost ya?
[18:57:23] <andypugh> After your free trial, Amazon Prime is just £79/year. Cancel anytime.
[18:57:44] <andypugh> (I have no difficulty resisting)
[18:58:18] <PetefromTn_> is it one of those you gotta remember to decline or they just go ahead and put the screws to ya LOL?
[18:58:34] <_methods> yeah i think it will autorenew
[18:59:51] <PetefromTn_> sheet
[19:00:01] <_methods> i probably do 50/50 amazon/ebay
[19:00:09] <_methods> but i've been happy with prime
[19:00:26] <PetefromTn_> it says its 99 a year tho
[19:00:31] <_methods> it is
[19:00:37] <PetefromTn_> Ok thanks
[19:00:46] <PetefromTn_> bbl gotta eat some din din
[21:43:45] <PetefromTn_> jeez man I go eat some dinner and work out in the shop and this place just DIES!! ;)
[21:45:06] <Wolf_> all your fault
[21:45:22] <Wolf_> and amazon prime is great
[21:45:25] <PetefromTn_> apparently
[21:45:38] <PetefromTn_> does this prime thing INCLUDE the TV part?
[21:45:55] <Wolf_> yeah
[21:46:25] <Wolf_> I’m watching back to the future on amazon prime vid via a Roku right now
[21:46:44] <PetefromTn_> nice
[21:46:58] <PetefromTn_> we have had netflix
[21:47:09] <PetefromTn_> but I understand amazon is decent as well.
[21:47:50] <Wolf_> it is, the few bucks to upgrade to overnight shipping has saved my ass a couple times on jobs
[21:48:50] <PetefromTn_> well I already did not accept the free trial and paid the fee for shipping...maybe next time.
[21:50:28] <Wolf_> just need to watch the marketplace vs fulfilled by amazon
[21:58:49] <Wolf_> sometimes amazon also marks stuff down to clear stock http://amzn.com/B000TIRZLK and I got http://amzn.com/B006M706CW x2 for $6.60 each
[21:59:38] <PetefromTn_> heh WTF is that thing?
[22:00:11] <Wolf_> handless dead blow knocker
[22:00:22] <Wolf_> handleless*
[22:01:03] <PetefromTn_> I think I would wind up smashing the crap out of a finger with that thing hehe
[22:01:22] <Wolf_> its pretty handy for seating stuff in the mill vice
[22:01:33] <Wolf_> and putting ikea stuff together :D
[22:02:03] <PetefromTn_> I have a nice mallet with two different heads for that but I actually need another hammer for work
[22:03:48] <PetefromTn_> I swear I must live in a freaking metal working black hole around here. There is almost NEVER a craigslist ad selling real metalworking equipment or machinery nearby me...
[22:04:25] <jdh> cali, kansas, penn. all seem good for equipment
[22:05:04] <PetefromTn_> yeah it seems like California is a used metalworking equipment nirvana sometimes...
[22:05:40] <Wolf_> this area is kinda slim for anything priced decent
[22:07:13] <Wolf_> I’m still wondering why that van norman ram type horizontal/vertical I found on craigslist for $500 hasn’t sold, its been on there for months now
[22:08:01] <PetefromTn_> probably because it is a BIG HEAVY HIGH HP machine that MOST people don't even know what the hell it is...?
[22:08:29] <Wolf_> I think the price is under scrap lol
[22:08:43] <PetefromTn_> even a small one of those older horiz/vert machines is very very heavy let alone a big one.
[22:09:48] <Wolf_> Listing: vertical/ horizontal ram by Van Norman non-op currently, needs some reassembly no tooling, Very heavy, 1940's era. bring cash and a rollback to take it. $500 firm
[22:12:30] <Wolf_> I sent them a message, I’ll find out how bad it is tomorrow afternoon lol
[22:15:46] <PetefromTn_> good luck man
[22:19:07] <Wolf_> could be fun...
[22:22:38] <PetefromTn_> surely
[22:22:39] <Contract_Pilot> hahahah walmart another 20 motors. Order cancled in 4 hours... Technical Price Error! hahaha! I think they caught on!
[22:23:17] <Contract_Pilot> Next time i see them will just buy a couple using wifes account.
[22:23:24] <Wolf_> lol
[22:23:26] <Contract_Pilot> See if they full fill them
[22:23:42] <bobo__> Pete how close is York,Pa from where you are ?
[22:24:54] <Wolf_> least I have them 470w nema34 servos, should work good for something big :D
[22:25:00] <bobo__> seems like Pa should have used machinery
[22:25:09] <Wolf_> york, pa is close for me, somewhat
[22:28:31] <PetefromTn_> pretty danb far
[22:30:52] <bobo__> Wolf that Van-Norman mill , you might want to check what collets are available for it. I think the are not a common type.
[22:31:33] <Wolf_> yeah, will have to see what the spindle is on it
[22:37:37] <ssi> Wolf_: I'm putting a stmbl together
[22:37:44] <Wolf_> cool :)
[22:37:47] <ssi> there's a bunch of parts on the pcb that weren't on the bom :/
[22:38:22] <ssi> wait maybe not
[22:43:43] <Wolf_> wonder what the cost would be to have a spindle taper reground or w/ever needs to be done to change it over
[22:45:38] <bobo__> Wolf may not be enough material/space in the spindle to change it
[22:46:19] <Wolf_> I’ll keep that in mind and take some calipers with me too then when I go look at it
[22:46:41] <Wolf_> http://jmkasunich.com/vannorman/VN_Spindle.htm
[22:47:13] <bobo__> also look at spindle speeds
[22:52:04] <Wolf_> I’ll be taking a load of pics and getting as much info off the machine before I decide to get it
[22:52:51] <bobo__> Or it gets you.
[22:53:21] <Wolf_> yup lol
[22:55:40] <bobo__> pis and mone if the overarm outboard spindle support is missing. I bet it is missing
[22:57:39] <bobo__> horz spindle overarm support bearing thing-e
[22:58:36] <Wolf_> I have no idea what that is lol
[22:59:00] <Wolf_> oh wait, http://www.practicalmachinist.com/vb/attachments/f19/35906d1309269494-van-norman-milling-machine-4810.jpg
[23:00:56] <bobo__> it supports the horz shaft at the outboard/far end ,for horz milling
[23:01:48] <Wolf_> yeah, its kinda obvious in that last pic I linked, but not knowing what model it is doesn’t help much (pic from goggle)
[23:06:14] <bobo__> always thought outside horz spindle supports for various older machines would be marketable items
[23:06:21] <Wolf_> its almost a hour drive to where that machine is so I’m going to go check it out in person first
[23:07:12] <Wolf_> will also help to see where it is how big it is so I can figure out which truck to take
[23:10:09] <bobo__> cast iron is heavy, and Van-Norman mills are not noted as being light weight
[23:11:02] <Wolf_> well I can take the f550 (can take 5tons) or the roll back
[23:13:44] <bobo__> to me most machines of that era were designed to maintain stated performace when sitting on a crappy wood floor
[23:14:55] <Wolf_> heh
[23:17:50] <bobo__> Hope it has a 40 or 50 taper spindle
[23:18:12] <Wolf_> yeah
[23:37:09] <fenn> "seems like California is a used metalworking equipment nirvana sometimes" are you kidding
[23:45:52] <Contract_Pilot> http://www.stevenrhine.com/wp-content/uploads/2015/10/Stepper-Driver-PSU-Lot-1024x576.jpg
[23:46:21] <Wolf_> lol
[23:47:34] <Contract_Pilot> Still awaiting one more.
[23:47:54] <Contract_Pilot> Still stuck in NJ....
[23:55:40] <Praesmeodymium> Contract_Pilot: can I sell ya a motor or 2?
[23:55:43] <Praesmeodymium> lol
[23:56:18] <Contract_Pilot> What did ya get that ya do not need?
[23:56:36] <Praesmeodymium> I was joking you have far too many for selling to you to make sense
[23:56:53] <Contract_Pilot> hahaha
[23:57:28] <Contract_Pilot> Chatting with the seller we were lucky to get the price we did.
[23:57:41] <Praesmeodymium> oh I am sure
[23:57:50] <Contract_Pilot> Said the price we got was an error/.
[23:57:55] <Wolf_> lol, I asked about tracking number for newegg order, reply in email “As such , we will issue a full refund for your purchase.” wtf lol
[23:57:56] <Praesmeodymium> I was hoping it was a typo or fire sale
