[00:05:42] <Mr_Mayhem> Heh, I had the same question for an open collector output on my VFD. (Not an input) It does not source current; it sinks, so I had to put field voltage to pull it up, so I used a 10k resistor to be sure not to fry something when it shunts to ground when on. The signal is spindle-at-speed output from VFD.

[03:01:16] <archivist> Valen, well past my bedtime !
[03:01:23] <Mr_Mayhem> CNCguy: I have not looked at those lathe features yet, looks like they are the kind of features that make use of encoder closed loop design.
[03:01:46] -!- GuShH_Lap has quit [Ping timeout: 240 seconds]
[03:02:05] <ries> Mr_Mayhem: they look very nice
[03:02:34] <Valen> we were after some clock gears in brass, and i figured, hey i know a guy who does that exact thing!
[03:03:03] <Mr_Mayhem> Hey archivist, you said earlier that steppers are not the future, you got me wondering what other ideas are floating around for future motion control.
[03:03:16] <Valen> SERVO!
[03:03:21] <archivist> servos
[03:03:24] <Valen> or linear motors if your keen ;->
[03:03:31] <Valen> (cyclical tech right?)
[03:03:54] <ries> steppers if you need something cheap, unless servo's become affordable :D
[03:04:03] <Valen> they are coming down
[03:04:23] <Valen> you can get 750W AC servos with drives for like $400 or so an axis as i recall
[03:04:50] <Connor> One thing about servos.. is tuning the PID and Closed loop
[03:05:15] <Valen> so archivist, want to make me some gears? ;->
[03:05:27] <Valen> big chunky ones
[03:05:31] <ries> I tend to see if you go pro, take servo... lot's of hobbyiests or some wood working type machines can get away with steppers..
[03:05:46] <Valen> 1.2mm brass up to 60-80mm dia
[03:05:50] -!- lyzidiamond has quit [Quit: lyzidiamond]
[03:06:17] <Connor> Steppers have their place.
[03:06:19] <archivist> Valen, mebe but you have the technology too and there is postage
[03:06:42] <Valen> to do it properly we would need 4th axis,
[03:07:18] <ries> night
[03:07:39] <Valen> I mean we can do it, but you already do do it ;->
[03:07:48] <archivist> bit thin for that diameter
[03:08:27] <Valen> yeah, that is a concern
[03:08:53] <Valen> but we do already have brass in that size which was the reasoning behind that ;->
[03:08:55] -!- terabyte- has quit [Quit: terabyte-]
[03:09:00] <archivist> I have seen some warping after cutting
[03:09:04] <Connor> Wouldn't it be better to make the gear thicker then face it down to 1.2mm ?
[03:09:26] <Connor> after the teeth are cut?
[03:09:57] -!- sumpfralle1 has quit [Ping timeout: 248 seconds]
[03:10:09] <Valen> I didn't think that'd be an issue in brass
[03:10:20] <Valen> see thats why I want to talk to you ;->
[03:11:08] <Valen> 3mm would look better
[03:11:26] <Valen> put a little radius on the edge of the gears
[03:12:58] <Mr_Mayhem> What are the gears to be used for? Just curious.
[03:13:42] <archivist> crossed out or plain
[03:15:15] <Valen> crossed out meaning spokes cut?
[03:15:45] <Valen> spokes would be nice but worst case we can cut those, centring on those wont matter much
[03:15:47] <archivist> yes
[03:16:03] <Valen> its going to be electrically driven but off batteries
[03:17:01] <Valen> so no particular accuracy requirement, but low friction is good
[03:19:36] <archivist> at this size (dia/thickness) mounting and arbour size get "interesting" so drilling some holes and screwing them to a plate to make a lot more rigid
[03:20:07] <archivist> but where and how have to be in mind of spokes

[09:38:47] <Mr_Mayhem> Is that for yourself or a client? Like, what would one make with it once it is working? Cabinets, house beams, Doors. I would do speaker enclosures for fun, ha.
[09:39:18] <Mr_Mayhem> Make some killer sub boxes heh.
[09:40:16] <kengu> it is sort of "joint" venture. as in it is for client but I will get full access to it and if they manage to do the products they are thinking with my help then I will get more money.
[09:41:44] <kengu> but yeah. I do not have experience with that kind of machines. ones that do not run linuxcnc in the end. ones that are this big or something that uses fibre optics to transmit signals. But I will learn
[09:42:44] <Mr_Mayhem> Oh, they use fiber? Good idea, to avoid interference.
[09:43:10] <Mr_Mayhem> I see, so you have access to it without needing to pay for it. Best of all possible worlds, I suppose.
[09:44:03] <Mr_Mayhem> I was thinking of this engineer I met in Rochester, NY.
[09:44:19] <Mr_Mayhem> He worked for Xerox and others in audio his whole life. Sold ultrasonic cleaners he designed for the medical field. Anyway, he had these huge diy bass horns filling the corners of his living room. Driving it with a 6" Radio Shack cheapie, he shook the house so bad stuff started falling off the wall.

[09:45:26] <Mr_Mayhem> With a machine like that, easy peasy.
[09:47:46] <Mr_Mayhem> Yeah, just play with it till it works kind of thing. With manual in hand, of course.

[09:50:00] <Mr_Mayhem> I had a hell of a time finding the manual for my VFD. One day, someone posted it in the cnc forum. It was like several months after I bought the machine.

[09:53:02] <Mr_Mayhem> But enough to learn from square one. Started with Linuxcnc on an old dell.
[09:53:40] <Mr_Mayhem> Yeah. I see how crazy it can get with toolchanger, and all kinds of other things to consider.
[09:53:50] <kengu> i did do plasma cutter conversion and laser cutter conversion and I did not do ncstudio->linuxcnc on the smaller (1400*2500) router (yet)
[09:54:42] <Mr_Mayhem> What do you use then in the meantime?
[09:54:53] <Mr_Mayhem> Same as above or Mach?
[09:55:25] <Mr_Mayhem> Oh, duh. Ncstudio.
[09:57:06] <Mr_Mayhem> It would be fun to work with a machine like that. I hear the plasma needs to have a height thing to keep it behaving as it goes.
[09:57:19] <Mr_Mayhem> Or something like that.
[09:58:09] <kengu> yeah. thc or atc to google if you need more info on that
[09:58:16] <kengu> there is not one on that plasma, yet.
[10:03:07] <Mr_Mayhem> So, the machines you do are for metal cutting. I wonder what they often make with such machines. Like I sort of know, but I don't really know what the plasma or laser cut parts are most commonly used for.

[10:05:32] <Mr_Mayhem> Here in Vegas there are many shops contracting work for the casinos, like decorative metal, marble, wall treatments, etc.
[10:06:29] <Mr_Mayhem> We have like 15 cnc related shops in town, by my estimate looking at google maps.
[10:09:51] <Mr_Mayhem> A bunch of waterjet places too.
[10:12:10] <kengu> cool .. perhaps
[10:12:29] <kengu> you do not have to have your own as there is some competition if you need to get something done
[10:12:37] <kengu> to get the price right
[10:12:51] <kengu> Mr_Mayhem: for wood mainly
[10:16:29] <ReadError_> I do a lot of G10
[10:18:54] <Mr_Mayhem> Really? I just cut my first printed circuit board. What do you make? Sounds like either PCBs or quadcopter frames. :)
[10:20:27] <Mr_Mayhem> I used the autoleveler app to correct for un-level board relatve to the tool, and my second board was perfect.
[10:20:44] <ReadError_> lol quads mostly
[10:20:53] <Mr_Mayhem> Nice.
[10:21:12] <Mr_Mayhem> That is a good application. How do you keep the dust down?
[10:21:43] <ReadError_> dust boot + 2 cyclone filters + hepa filter
[10:22:01] <Mr_Mayhem> Holy cow, you got serious!

[10:22:35] <Mr_Mayhem> Next I expect to hear cleanroom air management system.
[10:23:18] <ReadError_> nah this cuts down most the stuff
[10:23:37] <Mr_Mayhem> Wow. what cutter tools (company wise) do you prefer? I know G10 is harsh on tools.
[10:24:13] <ReadError_> i use burr endmills mostly from ebay, kyocera (spelling?) mostly
[10:24:59] <Mr_Mayhem> Yep. Are they also called chip breaker end mills? I have those.
[10:25:34] <Mr_Mayhem> Like they have lots of tiny spikes flared out on the surface of the tool, and a spiral pattern.

[10:30:36] <ReadError_> cambam now mostly
[10:31:43] <Mr_Mayhem> Cool. So I guess you sell kits and people put them together?
[10:33:18] <Mr_Mayhem> I was following crudcnc on youtube, and he was doing something like that, for quadcopters. He made camera mounts or something.
[10:34:27] <Mr_Mayhem> Nice footage of ships at sea filmed from his quadcopter. He works on the ship, and brought his heli along to film the ship on a gopro hd camera.
[10:34:36] <ReadError_> i make some of my own stuff but lately ive been doing alot of work for others

[10:38:33] <ReadError_> yea the clamps are great
[10:41:17] <Mr_Mayhem> I want to see someone make an rc gyro computer using HAL from linuxcnc's innards. Hehe. Run it on a beaglebone.
[10:41:39] <Mr_Mayhem> Lord knows it handles servos and is fast enough.
[10:41:57] <archivist_herron> hal needs better maths for that
[10:42:17] <Mr_Mayhem> Yeah, kapfman filters or whatever.
[10:43:15] <Mr_Mayhem> Have it land on something, and cnc it, and fly away, hehe
[10:43:37] <Mr_Mayhem> Ok, that was too much.
[10:44:26] <Mr_Mayhem> But nice work on the quad copters. I love those videos on you tube with them flying in all different cities like a tour. Forget the name of the group.

[11:38:58] <Mr_Mayhem> Is there a difference in quality of the inside color? Some look like they are only black on the outside surface.
[11:39:20] <Mr_Mayhem> But maybe that's the camera or lighting on the cut. I don't know.

[11:59:00] <jthornton> like these?
[11:59:22] <MacGalempsy> one looks like that
[11:59:48] <jthornton> cut off a bit of tube to get a fresh place to seal to, if that fails replace the fitting
[12:00:14] <MacGalempsy> thats what I was afraid of. the really leaky one is part of the manifold
[12:00:22] <MacGalempsy> the tubing is new
[12:00:43] <jthornton> as in a all in one manifold with the fittings molded in?
[12:01:17] <MacGalempsy> it looks like it could be component
[12:01:48] <jthornton> some fittings have an internal hex for an allen wrench

[17:47:43] <Mr_Mayhem> a bit choppy here in Vegas.
[17:47:55] <Mr_Mayhem> that livestream.
[17:48:16] <IchGuckLive> im trying to chop all the viewers inside the room
[17:48:26] <IchGuckLive> wait 20sec
[17:48:38] <Mr_Mayhem> ok
[17:48:52] <Mr_Mayhem> Yeah, cuts the congestion.
[17:49:50] <Mr_Mayhem> Usually the treckies are in Vegas, the other way around:-)
[17:50:06] <Mr_Mayhem> Or la
[17:53:36] <Mr_Mayhem> It dropped and is now back up and choppy.
[17:54:40] <Mr_Mayhem> I guess two screens is too much this far away.
[18:03:15] <IchGuckLive> Mr_Mayhem: now it shoudt work only 20 inside the lan and 5k viewers

[18:14:07] <Mr_Mayhem> It played for a bit choppy and died again. The pageload is slow, so maybe just latency to me is the issue, like high ping time. Anyway, I don't want to fill this room with star treck signal reports. Looks like a fun show, though. I never heard folk music like that played by people in star treck uniforms.:-)

[23:44:16] <ries> mozmck: my recent exprience with libreCAD seems to indicate that even if it's GPL there is nothing what I can do for people to fork, re-copyright it and sell. LibreCAD is found in the appstore and Apple isn't taking it down :s so I cinda wondering what would be the best for the project... if somebody is interested :D
[23:45:15] <mozmck> I think the re-copyright would be problematic, but you can always fork and sell a GPL project.
[23:45:47] <ries> they are just bluntly selling it with a re-copyright without giving the source
[23:46:08] <ries> I am just now wondering what's better project whise
[23:46:52] <mozmck> Interesting. I think there is a group that will take them to task for that if you let them know, but I don't remember who.
[23:48:16] <mozmck> I would think it would just depend on your goals/ideals.
[23:51:01] <ries> Hopefully next week...I wrote it in java so they can't sell it on the App store anyways :D (as far as I know....)
[23:53:26] <jdh> tjb1: what is your part?
[23:53:28] <Spida> tjb1: would probably be helpful to know on which continent your are located if you want the fnished part sent to you...
[23:55:08] <tjb1> NY, USA and yes
[23:56:58] <tjb1> jdh: It would be this

[23:57:12] <tjb1> If you can do it I would of course have a real print and not chat talk or napkin sketches ;)
