[02:55:51] <pink_vampire> hi
[02:56:46] <pink_vampire> morning
[04:36:33] <Meduza> Is there anyone who sells a ready to go industrial pc made for Linuxcnc?
[04:49:44] <archivist> Meduza, not as far as I know,
[04:50:25] <pink_vampire> tormach
[04:50:34] <pink_vampire> path pilot
[04:51:07] <archivist> that is not pure linuxcnc
[04:53:07] <Meduza> I am involved in a project where we probably are going to use LinuxCNC to control the machine (not a lot of cnc controllers out there that are very flexible, does not cost serveral 10k€ etc and can provide 7-9 axis of control), and i would prefer to use hardware known to work well instead of just guessing...
[04:54:07] <enleth> Meduza: what is that machine? 7-9 axes sounds interesting
[04:55:04] <archivist> Meduza, there are many PD boards known to work though
[04:55:09] <archivist> PC
[04:56:23] <Meduza> enleth: the base is a cnc gantry router with three toolheads, and one of the toolheads will be a custom built thing that can pan/tilt and turn a tool around itself
[04:57:10] <Meduza> so it is X, Y, Z1, Z2, Z3 and A B C to explain it in a simple way :-)
[04:58:46] <archivist> one head at a time or all three or a combination
[04:59:05] <Meduza> one head at a time usually
[04:59:31] <Meduza> you can think about it as a crazy heavy toolchanger :p
[04:59:53] <archivist> some might just make a head changer :)
[05:02:37] <Meduza> The reason to do that would be to not have to move all the weight around, but in this case one of the heads will be 80% of the weight and be used 80% of the time, so it does not make a lot of sense to make a very complicated setup to change heads
[05:05:12] <archivist> loss of travel due to the other two heads is a thing I am thinking about
[05:05:31] <XXCoder> why cant just use other tools as that head tool?
[05:05:52] <enleth> XXCoder: I imagine that completely different speed ranges could be a valid reason
[05:05:55] <XXCoder> I have seen setup where one attaches dermel to milling head as tool, sideways to do 90 degree holes
[05:06:11] <XXCoder> enleth: dont matter as that tool handles speed anyway lol
[05:06:21] <archivist> this sounds more serious than dremel
[05:06:25] <enleth> XXCoder: it does in practice
[05:06:36] <XXCoder> archivist: yea
[05:06:51] <enleth> XXCoder: say, a woodworking Kress spindle with a 20k-100kRPM speed range and a metalworking 100-3000RPM spindle
[05:07:00] <enleth> XXCoder: you just can't do that with a single one
[05:07:11] <archivist> yet :)
[05:07:23] <XXCoder> archivist: what was strange is that mill head was using to turn dermel to correct angles lol
[05:07:30] <XXCoder> *used
[05:07:44] <XXCoder> enleth: you seem to have misunderstood what I meant. lol
[05:07:56] <archivist> is a dermal skin powered
[05:08:13] <enleth> XXCoder: no, I just gave a valid reason to have two separate heads
[05:08:33] <XXCoder> enleth: im talking attaching one spindle to other as tool
[05:08:39] <XXCoder> enleth: that solved speed issue..
[05:08:53] <enleth> XXCoder: attach a 3kW Kress as a tool
[05:09:05] <enleth> go ahead, I want to see it flop down under its own weight
[05:09:09] <XXCoder> though there is height limitions hmm
[05:09:17] <XXCoder> anyway
[05:09:28] <XXCoder> Meduza: whats other 2 heads do anyway
[05:09:30] <enleth> no, there are rigidity limitations
[05:10:20] <enleth> archivist: I guess spindles that can do 100-100k at full rated power might exist, but I don't even want to know the price
[05:10:25] <Meduza> In this case, the tool head that can rotate in 3 axis is not a rotary tool at all, one is a 3kw spindle
[05:10:36] <Meduza> and the third is not used atm
[05:10:50] <Meduza> but exist for a idea we will be developing
[05:11:43] <Meduza> the loss of travel is no problem, we "only" need ~900mm and we get that without problem even with the three head setup
[05:12:18] <XXCoder> nice
[05:13:00] <Meduza> even ordered the machine with the gantry made for single head, since i did not need the full 1280mm working width
[05:13:11] <Meduza> and prefer a compact machine
[05:13:26] <Meduza> (usually the 3 head version has a longer boom)
[05:14:18] <XXCoder> too damn bad im going car shopping at morning
[05:14:29] <XXCoder> or I'd be wiring up tb660s and BOB finally
[05:16:08] <XXCoder> I hate car shopping. :( thats why I just keep driving car for years
[05:16:37] <enleth> by the way, I've almost finished wiring 7i77 into the bridgeport
[05:19:19] <enleth> all I need now is to mount encoder interpolators somewhere so they don't hang off their cables, and get some shielded cabling to connect servo drive inputs properly
[05:47:57] <jthornton-> morning
[05:48:21] <XXCoder> hey jthornton
[05:48:34] <jthornton> what's up today?
[05:48:36] <XXCoder> did I menion I got my controller boards and BOB?
[05:48:49] <jthornton> yes
[05:49:05] <XXCoder> yea. I planned to wire em tomorrow but guess not
[05:49:08] <XXCoder> need to buy a car bleh
[05:49:17] <jthornton> old one died?
[05:49:32] <XXCoder> well its still drivable
[05:49:36] <XXCoder> but not reliable
[05:49:42] <XXCoder> it idles so rough at stops
[05:50:04] <jthornton> do a tune up
[05:50:21] <XXCoder> nah wiring is shot
[05:50:28] <XXCoder> few other fun issues
[05:50:44] <CaptHindsight> undersized Nissan wiring
[05:51:00] <jthornton> I need to rebuild my truck engine this winter
[05:51:16] <jthornton> started using oil and smoke puffs out when you start it
[05:51:26] <CaptHindsight> early retirement ECU firmware
[05:51:27] <jthornton> only has 150,000 miles
[05:51:29] <XXCoder> CaptHindsight: nah something happened, dunno what it was. it burnt left headlight socket and broke some stuff with it
[05:51:38] <XXCoder> near 200,000 miles
[05:52:11] <XXCoder> o2 sensor heater dont work for example. sensor reistance works but it cant get any power. summer it was still fine because engine heats it anyway
[05:52:18] <XXCoder> but now in winter it dont heat up
[05:52:21] <CaptHindsight> jthornton: what engine?
[05:52:29] <jthornton> 350
[05:52:38] <jthornton> chevy
[05:53:23] <CaptHindsight> better than the old Chevys, I can still smell the oil :)
[05:55:27] <jthornton> I went through 3 engines and a dozen transmissions on my 81 custom deluxe
[05:56:01] <CaptHindsight> how many miles did you get out of the body?
[05:56:15] <archivist> 12 miles
[05:56:16] <jthornton> the 81 is still running lol
[06:03:48] <jthornton> the internet says to change the pcv valve first then the valve seals, I need to take the intake manifold off and fix the knock sensor wires that the rats chewed...
[06:04:04] <jthornton> XXCoder: you shopping for a new vehicle or new to you?
[06:04:36] <XXCoder> used
[06:04:50] <jthornton> twice the fun
[06:05:30] <archivist> must have known history if you want reliable
[06:05:37] <CaptHindsight> jthornton: up to a few years ago I used to drive only 73' and earlier
[06:05:40] <XXCoder> im waiting for elio, I just want good used for couple years.
[06:05:47] <jthornton> I wonder if carfax is really worth it
[06:05:58] <XXCoder> heard its good
[06:06:01] <XXCoder> my sis liked it.
[06:06:36] <archivist> erm womans car <> mans car
[06:06:52] <jthornton> lol
[06:06:54] <XXCoder> how ya know? my sis might have large truck
[06:07:01] <CaptHindsight> I just look at the car and look up it's general problem history
[06:07:08] <XXCoder> my "sis in law" certainly does.,
[06:07:35] <XXCoder> (quotes because my bro is one who married into that family not me)
[06:07:49] <jthornton> around here girls hunt in pink cammo and have a gun rack on their truck lol
[06:08:19] <XXCoder> "so what are you doing to do when you lose your job in 6 months"
[06:08:21] <XXCoder> uhhh'
[06:08:29] <XXCoder> is that a threat?'
[06:09:30] <XXCoder> email spam gonna love em :P
[06:15:37] <CaptHindsight> jthornton: are the Hello Kitty rifles popular with them as well?
[06:16:34] <jthornton> some like them
[06:18:21] <CaptHindsight> jthornton: I'm running int the same problem as you with getting high speed internet in the country
[06:19:23] <jthornton> dang fiber cable is 1.6 miles from my house but it's not hooked to anything so it's a waste of money to put it in lol
[06:19:57] <CaptHindsight> I passed on two building that were only 100 yards from the end of the cable
[06:20:19] <CaptHindsight> Comcast wanted $15K to go the extra distance
[06:21:21] <XXCoder> that is because they are comcast
[06:21:37] <CaptHindsight> most of the trees around here have been cleared for corn fields so a cooperative wifi setup is possible
[06:21:55] <XXCoder> or use cannentas
[06:22:04] <XXCoder> other name is easier to find: pringo can
[06:22:40] <XXCoder> pringle can radio
[06:22:43] <CaptHindsight> they get soggy after a few weeks
[06:22:58] <jthornton> we had radio modems for a while but some ass wipe sued the company saying the antenna made lightning strike his house more often
[06:23:00] <XXCoder> just put it in plastic box
[06:23:10] <XXCoder> plastic isnt visiable to radar. so no inference.
[06:23:39] <CaptHindsight> XXCoder: just build or buy a proper antenna
[06:24:00] <XXCoder> yeah friend of mine bought cannenta
[06:24:07] <XXCoder> its like pringle but all metal
[06:24:15] <XXCoder> hell of range.
[06:25:28] <CaptHindsight> https://www.524wifi.com/index.php/catalog/product/view/id/556/s/jirous-parabolic-antenna-jrc-29dbi-extrem-dualpack/
[06:26:20] <XXCoder> pretty expensive,
[06:26:38] <XXCoder> im using wifi dongle that has standard RF connector lol
[06:26:48] <XXCoder> means I can use one of those that uses mini RF connector
[06:29:29] <XXCoder> lol
[06:29:30] <XXCoder> https://www.youtube.com/watch?v=_1WKwtSr3c0
[06:29:33] <CaptHindsight> XXCoder:
https://en.wikipedia.org/wiki/Cantenna#/media/File:5ghz_cantenna_as_satellite_dish_feed-horn.JPG
[06:29:38] <XXCoder> he turned his drill press into wood mill :P
[06:30:04] <XXCoder> ingenious really
[06:33:11] <XXCoder> couple nemas and controller and he has cnc drill press
[06:35:31] <CaptHindsight> XXCoder:
http://martybugs.net/wireless/antennacomp.cgi
[06:37:47] <XXCoder> interesting
[07:42:36] <jthornton> finally got my list of files in the correct order newest on top lol
[07:42:47] <jthornton> time to workout now
[08:13:17] <Tom_L> jthornton cool
[08:15:36] <Tom_L> jthornton, you know.. if they're in decending order there may not be a need for multiple directories
[08:30:39] <jthornton> for the #linuxcnc directory?
[08:30:57] <jthornton> yes I agree, thinking of putting year links at the top lol
[08:31:26] * jthornton cools down after a good workout
[08:31:46] <XXCoder> if setup (year)-(month)-(day) it will always sort well by filename
[08:31:52] <XXCoder> if you want date made
[08:32:23] <jthornton> the log files have names like 2016-10-12.html
[08:32:33] <XXCoder> indeed
[08:32:41] <jthornton> so they sort well with sorted()
[08:32:53] <jthornton> once they are in a list
[08:33:07] <jthornton> >>> for d in os.walk(log_dir).next()[1]:
[08:33:07] <jthornton> ... print d
[08:33:07] <jthornton> ... for f in sorted(os.walk(os.path.join(log_dir,d)).next()[2]):
[08:33:07] <jthornton> ... print f
[08:33:31] <XXCoder> hopefully not entire source code pasted.. lol
[08:34:01] <jthornton> no, just the bit that sorts the directories and files
[08:34:04] <XXCoder> one time I pasted over 100 pages of text into irc. :P had to leave so it would stop sending
[08:34:13] <jthornton> lol
[08:34:27] <XXCoder> only got to over one page. good thing hexchat dont instantly spam
[08:36:16] <Jymmm> XXCoder: You could have just closed your irc client
[08:36:40] <XXCoder> Jymmm: thats what I said... :P
[08:36:56] <Jymmm> XXCoder:butha didnt do it, did ya?
[08:37:25] <XXCoder> ok whateevr you wanna belive, whatever helps you pleasure your sigificant other lol
[08:38:09] <Jymmm> Uh huh, cough *BULLSHIT* cough
[08:38:40] <XXCoder> oh you having sigificant other is bullshit? sorry to hear that. someday you will find someone perfect for you im sure :D
[08:45:40] <jthornton> shower time!
[08:45:54] <XXCoder> heey keep that persona]
[08:45:55] <XXCoder> ;)

[09:05:52] <JT-Shop> too late in the day... 8am is free time cut off
[09:06:29] <JT-Shop> XXCoder: the X axis came out nice with the 40mm print fans, not perfect but workable
[09:07:13] <JT-Shop> holes are about 0.02mm undersized so a little reaming to size and I think it will work
[09:07:19] <Nick001> JT-you handle mesa cards?
[09:07:39] <JT-Shop> mesaus.com
[09:07:41] <JT-Shop> yes
[09:08:35] <Nick001> do you have a 7i37TA in inventory in MO?
[09:09:01] <JT-Shop> yep
[09:09:28] <Nick001> tele orders?
[09:10:27] <JT-Shop> I can't take a cc over the phone...
[09:11:49] <JT-Shop> well I could write it all down and pretend to be you and enter the order online and pay with your cc
[09:12:02] <Nick001> paypal at the site? could you ship today
[09:12:37] <JT-Shop> if you hurry and I only use paypal to take cc or you can use a paypal account to pay
[09:13:27] <Nick001> as soon as I find your # at the site
[09:14:12] <JT-Shop> pickup is 10am and I have to leave at 9:30 to make that otherwise it sits until the next day at the post office
[09:15:59] <Nick001> what about UPS
[09:16:37] <JT-Shop> I'm not sure about their schedule
[09:16:56] <JT-Shop> hurry up and place the order and I'll do my best to get it out today
[09:17:42] <Nick001> you'd be useing my ups account - you at that #
[09:18:41] <JT-Shop> ?
[09:19:55] <JT-Shop> I can drop it off at ups later today, I have to run to the post office with todays shipments then head to Van Buren to fix a lumber dip tank that has been down for a week
[09:24:40] <Jymmm> Oh noes, the lumber can't relax in the hot tubs!!!
[10:27:13] <pink_vampire> http://i.imgur.com/HIgHrX4.png
[10:27:45] <pink_vampire> brushed aluminum part that i did
[10:31:01] <cradek> pretty
[10:37:50] <Jymmm> pink_vampire: So, how does that part you made clip nails? ;)
[10:38:22] <Jymmm> cradek: Did you see the utility van conversion?
[10:38:31] <cradek> no
[10:38:45] <pink_vampire> it's the wire duck holder
[10:39:44] <pink_vampire> and i'm going to cut my nails soon
[10:40:17] <Jymmm> cradek: 016-10-19.08:44:46 Jymmm: cradek: Thought you might appreciate this... utility van converted to camper...
https://www.youtube.com/watch?v=wksm1xI1Ms0
[10:40:58] <Jymmm> pink_vampire: It they make you happy don't, I'm just pullin your chain ;)
[10:41:57] <SpeedEvil> http://imgur.com/gallery/dteLm
[10:42:22] <pink_vampire> i like them looong, but few of them start to split, and i want to play my violin again
[10:43:11] <Jymmm> pink_vampire: ah
[10:43:50] <pink_vampire> after 2 years, time to cut them and start again
[10:43:54] <Jymmm> SpeedEvil: CaptHindsight
http://i.imgur.com/5NKFkdj.jpg
[10:44:43] <Jymmm> pink_vampire: Oh come on, you know you just want to wipe your butt conveniently again. It's okey, we get it ;)
[10:45:10] <pink_vampire> i never do it
[10:45:36] <Jymmm> pink_vampire: You never wipe your butt? And your shit don't stink either, right?
[10:45:47] <pink_vampire> correct
[10:45:53] <Jymmm> pink_vampire: gotcha =)
[10:46:04] <pink_vampire> i'm using bidet
[10:55:18] <miss0r> o_O
[10:55:30] <pink_vampire> miss0r: ??
[10:55:31] <miss0r> One should never read back a few lines after being away
[10:55:39] * Jymmm pokes miss0r other eye to make them the same
[10:55:42] <miss0r> and not read it all lol :)
[10:55:50] <miss0r> Whats wrong with the bidet?
[10:56:36] <pink_vampire> nothing, it's the best thing ever made
[10:56:48] <miss0r> With these new aqua clean toilets.. I get it. The butthole is the only place on the body we are content with cleaning poo off just with paper...
[10:57:29] <miss0r> I'm just not ready to take the step :) I would have to get one of thoes combined units, because my bathrooms are quite small
[10:57:37] <pink_vampire> i don't like toilet paper,
[10:57:41] <miss0r> i'm basically showering with one foot in the toilet
[10:57:42] <malcom2073_> miss0r: They sell units that attach to normal toilets
[10:58:22] <miss0r> malcom2073_: i'm sure its the future, and I respect people using it- i'm just not ready
[10:58:33] <malcom2073_> Fine, but tailor your excuses to reality :-P
[10:59:07] <miss0r> we have all had a bowelmovement that dictated a shower afterwards.
[10:59:19] <malcom2073_> Indeed
[11:00:18] <miss0r> heh, I always get sidetracked when someone is talking toilet talk... This is why after a few minuts at any dinner party, sitting next to me becomes a job
[11:00:50] <miss0r> back to milling this drillpress table somewhat flat again.
[11:01:02] <Jymmm> miss0r: lol
[11:01:28] <pink_vampire> someone know about cnc milling projects?
[11:01:36] <malcom2073_> Many people
[11:01:48] <miss0r> thats a pretty vauge question, i'd say
[11:01:52] <Jymmm> And their shitty jobs too =)
[11:01:58] <Jymmm> they're*
[11:02:51] <miss0r> Jymmm: not at all - do like me, and stuff the half complete project in the bottom of a closet, and forget about it
[11:03:21] <Jymmm> miss0r: haha
[11:04:04] <miss0r> I have a 2/3 complete 5-axis mini cnc mill in here. I have started scrapping it for parts thou. I came to the conclusion I would never finish it
[11:06:28] <miss0r> mleh! my plate metal stock takes a leap form 10mm to 35mm - and I need 12. This sucks !
[11:06:53] <sync> weld on some material
[11:07:11] <miss0r> solution one: make something too flimsy for actual use OR spend the rest of the day stripping alot of good material down
[11:07:39] <Frank_20> jymmm: why cnc milling is a shitty job? i am between 3 different cnc machine types to build
[11:08:19] <Jymmm> Frank_20: shitty, as in pita or difficult, etc
[11:08:21] <miss0r> sync: yeah.. I find this method overrated. And I would have no real way of getting them put together properly "in the middle" other than drilling the bejesus out of it.
[11:09:12] <sync> I mean welding on the 2mm.
[11:10:26] <miss0r> sync: project eksplained: I am going to mill away 11mm of cast iron from this drillpress table. Then I am going to make 3 new peices to put on top, to replace the drilled out material there. I can't concieve of a way welding on 2mm to a 10mm plate would do this job properly
[11:10:31] <miss0r> Please do elaborate
[11:11:33] <sync> well, your plate will then be thicker than 10mm
[11:12:45] <miss0r> yeah, but how would you weld it, to act like one massive block?
[11:16:01] <sync> by laying down bead after bead
[11:17:25] <miss0r> Now I get it. You didn't want to add a 2mm plate to a 10mm plate... Yeah. That sounds like I would use as much time welding as I would milling down the 35mm.. Also, I would get some super strange material out of it. The weldings are harder than the steel I'm using for this
[11:44:21] <miss0r> milling cast iron is a bit too noisy for my liking
[11:46:13] <archivist> cast is wonderful
[11:46:28] <miss0r> and all the interrupted cuts does not make it sound better. This table is like a swiss cheese
[11:47:01] <archivist> I expect a shine when done
[11:47:07] <miss0r> archivist: I enjoy drilling in it as well. but I don't like facing it
[11:48:08] <miss0r> archivist: That is no problem. The surface is quite nice looking, but it sounds horrible with this mill doing 4k rpm in cast iron, no matter wich way you twist it
[11:48:10] <archivist> last bit of cast I worked on, was a stick of continuous cast
[11:48:29] <archivist> 4k seems a lot too fast
[11:49:25] <miss0r> 12mm tungsten carbide bullnose endmill, 4k rpm at 800mm/min feed
[11:49:30] <miss0r> Sounds about right to me
[11:49:45] * miss0r don't own a facemill yet
[11:49:55] <archivist> in steel maybe
[11:50:08] <miss0r> Well, I have one, but the inserts are impossible to figure out
[11:50:15] <miss0r> you would do lower rpm?
[11:50:42] <archivist> on cast iron yes
[11:51:18] <miss0r> I know it is alot harder.. but to quite a TV personality I like: "POWEEER!!!!"
[11:51:38] <miss0r> Jeremy Clarksson, if in doubt
[11:52:01] <miss0r> quote*
[11:53:37] <miss0r> Don't get me wrong. it sounds right, it is just LOUD
[11:54:41] <miss0r> anywhy, This is it for me tonight. I have to get dinner with the misses. have a good one
[11:55:14] <archivist> try to find out what is vibrating
[12:08:07] <CaptHindsight> http://www.multiplaz.com/about plasma welding, cutting and soldering
[12:08:43] <CaptHindsight> " water-alcohol solution instead of shielding gas"
[12:10:15] <IchGucksLive> hi
[12:10:28] <archivist> a contradiction "allows you to melt even thick 12 inch (300 mm) metal to the depth of up to 7/16 inch (10 mm)"
[12:10:42] <Jymmm> cradekwhat did you think of the utility van conversaion?
[12:10:51] <Jymmm> cradek what did you think of the utility van conversaion?

[12:12:17] <cradek> it's neat. I see the appeal of having the sink and cooking but no toilet
[12:12:42] <CaptHindsight> what are the woods for anyway?
[12:12:44] <Jymmm> cradek: Yeah, I love that sink/stove, but it's $400 without the faucet =)
[12:12:45] <cradek> the toilet part is just as yucky as you'd expect
[12:14:02] <Jymmm> CaptHindsight: firewood
[12:14:25] <Jymmm> cradek: Heh, have a trap door in the floor and a manhole cover lifter =)
[12:16:51] <CaptHindsight> https://youtu.be/1cRW-aQ4TDc?t=5m5s not too pretty "Impossible Welds made Possible with Multiplaz"
[12:20:38] <IchGucksLive> CaptHindsight: use c4
[12:25:48] <IchGucksLive> my new vid uploaded a hotwire xyuv chuck

[12:40:53] <CaptHindsight> heh Expired due to failure to pay maintenance fee
[12:49:27] <Cromaglious_> hmmm every 15minute I was falling off...
[12:49:49] <Tom_L> get a longer rope
[12:49:57] <IchGucksLive> Cromaglious_: as long as you stanfd its ok #
[12:50:31] <IchGucksLive> the ruoter is logging you out for traffic reason
[12:51:29] <Cromaglious_> and yesterday my main laptop decided to shutdown due to over heating....
[12:52:03] <CaptHindsight> Tom_L: you think he might have this problem?

[12:52:18] <Cromaglious_> My other laptop a IBM T60 wouldn't play youtube for anything... I'd get 15 seconds of a video then youtube would pop up the ERROR
[12:52:41] <CaptHindsight> Cromaglious_: but you have a great keyboard
[12:53:02] <Cromaglious_> Logitech K330 wireless
[12:53:52] <Cromaglious_> This computer is my linuxcnc machine an ITX atom 1.4ghz.. doesn't play youtube for shit...
[12:54:15] <CaptHindsight> the T60 had one of the best laptop keyboards ever made
[12:54:34] <Cromaglious_> yeah it's keyboard is pretty good..
[12:57:37] <Jymmm> CaptHindsight: And the T60 had MAJOT overheaitng issues too
[12:57:42] <Jymmm> MAJOR*
[13:01:00] <IchGucksLive> Folks a question if i clone the drive to a exact the same PC and do A Latency i get not expected numbers well above 100k if i install frech 12.04 and then pae i get as low as 8000
[13:01:43] <IchGucksLive> is this true to a internal kernel patch only on real install
[13:13:00] <IchGucksLive> no answer
[13:13:30] <distrozapper> IchGucksLive, I don't understand quite: What steps did you go? You cloned some drive and placed it into "same PC"? You are sure it is configured _exactly_ (By BIOS, processor, mainboard) as the "source" system ?
[13:13:41] <IchGucksLive> im off i drilled 28H7 mm today 240 hles
[13:14:04] <IchGucksLive> yes it is
[13:14:16] <IchGucksLive> i got 20pc same
[13:14:29] <IchGucksLive> for 12 mashines and 8 in spare
[13:15:54] <IchGucksLive> Gn8 to be continoued

[13:24:36] <MacGalempsy> the illustrious cnc gluegun took a dive today...
[13:24:59] <MacGalempsy> but it is climbing back up...
[13:31:03] <CaptHindsight> Jymmm: major issue or general problem? :)
[13:31:35] <CaptHindsight> at least it wasn't a colonel bug
[13:36:51] <Jymmm> CaptHindsight: Known issue, unable to be resolved even at the repair facility, it still is an issue.
[13:36:57] <Jymmm> post repair that is
[13:38:48] <CaptHindsight> http://www.ebay.com/itm/PHOENIX-CONTACT-DIK1-5-LA-TERMINAL-BLOCK-3LEVEL-INITIATOR-300V-15A-28-14AWG/121044445181 is there a tool to separate these after adding the common bus bar?
[13:39:04] <CaptHindsight> ^^(the blue strip)
[13:39:41] <Jymmm> pocket screwdriver?
[13:40:08] <CaptHindsight> bends them
[13:40:30] <Connor> CaptHindsight: Are they not screwed in together?
[13:40:33] <CaptHindsight> they seem designed to stay put
[13:40:44] <Connor> I think you have to unscrew all of them.. pull the strip, then cut it..
[13:41:02] <CaptHindsight> Connor: no screw, the plastic strip is locked in tightly
[13:41:35] <CaptHindsight> prying on the strip bends the contacts below
[13:55:22] <Jymmm> CaptHindsight: I said a pocket scrwdriver, not a crow bar
[14:00:32] <CaptHindsight> Jymmm: I've asked you nicely before to leave me out of your online fantasy preversions :)
[14:02:54] <Jymmm> CaptHindsight: You are WAY TOO UGLY to be consider for a fantasy
[14:03:49] <Jymmm> CaptHindsight: But... you're an EXCELLENT candidate for one's worse nightmare
[14:18:35] <Jymmm> CaptHindsight: Don't worry though... we still luv ya =)
[14:25:34] <XXCoder> JT-Shop: nice!
[14:26:01] <XXCoder> getting ready to go buy a car
[14:44:22] <Demure_> So on my Emco F1, the original stepper motor cables go to the front, then out through the back. Is there any point to this over pointing the cables downwards or backwards straight towards the hole of the enclosure? (
http://www.lathes.co.uk/emcomiller/img21.jpg )
[14:55:52] <Jymmm> Demure_: travel clearances
[14:56:05] <Jymmm> you dont want to SMASH the connectors
[14:56:17] <Demure_> Ah, fair enough, thanks. :)
[14:56:24] <Jymmm> Thats's the only thing I could think of
[14:56:51] <malcom2073_> Seems like forward to back makes a better service loop than straight back
[16:01:35] <Demure_> Also, is having a power supply with the right voltage but way way overkill (I miscalculated the watts needed by tenfold, stupid stupid stupid) when it comes to amps?
[16:06:27] <lowridah> it's just likely to have a much lower PE factor is all
[16:06:37] <lowridah> which likely doesn't matter to you
[16:21:52] <The_Ball> Any tips on driving a 24V AC relay from a 7i77?
[16:24:02] <pcw_mesa> probably via another relay or SSR
[16:25:09] <The_Ball> Yeah that's what I thought. Would be easier with a 7i37 and two IOs
[16:25:17] <pcw_mesa> AC relays will overheat on same voltage DC and may stick (not release)
[16:25:39] <The_Ball> Yes I've heard that before, so I'll stick with the specified AC voltage
[16:26:10] <pcw_mesa> what current?
[16:26:45] <The_Ball> I haven't got it in front of me ATM, but I'm going to guess in the 100mA range
[16:29:02] <cradek> a black opto22?
[16:30:49] <pcw_mesa> I have a little quad OPTO board that will drive it but not released yet
[16:30:51] <pcw_mesa> 4-24V in 0 --24 AC/DC out normally uses CP1017 (100mA) but can use CPC1018 (600 mA)
[16:31:28] <cradek> The_Ball: do you need one of these, or many?
[16:32:12] <The_Ball> cradek, nah not many, might only be the one actually for flood coolant, a three phase contactor
[16:32:35] <The_Ball> I might just go the easy route with a small DC relay
[16:32:50] <cradek> a relay running a relay running a contactor?
[16:32:52] <MarkusBec> pcw_mesa: is it possible to power the 7i92 thru P2 or P1 and leave p3 open
[16:33:52] <The_Ball> cradek, no, 7i77 running a DC relay running a AC relay/contactor. I'm not sure when a relay becomes a contactor
[16:34:28] <pcw_mesa> Yes if jumpered correctly
[16:34:41] <MarkusBec> ok thanks
[16:35:13] <pcw_mesa> if not jumpered correctly you will put 5V on the 3.3V bus and fryola
[16:36:47] <nubcake> hi
[16:37:02] <The_Ball> cradek, this is for the lathe dead controller retrofit I'm working on. I think I showed you the panel last time
[16:37:16] <cradek> The_Ball: OAC5 are just a few bucks
[16:37:24] <The_Ball> this one
https://owncloud.wigen.net/index.php/s/2oFLZkbqkqCh5X5
[16:37:26] <cradek> http://www.ebay.com/itm/Opto-22-G4-OAC5-Module-120vac-3A/351647362400
[16:37:51] <cradek> what's the contactor coil rating?
[16:37:57] <nubcake> uhm.. how much would i have to pay for a decent lathe to start with? any ideas?
[16:38:28] <The_Ball> I'll have to check tomorrow. Postage from the states is usually a killer so I get a lot from ebay/china
[16:38:56] * The_Ball looks at pcw_mesa
[16:39:07] <MarkusBec> pcw_mesa: yeah grilled fpga on toast
[16:39:08] <cradek> they're everywhere
[16:39:09] <CaptHindsight> nubcake: define decent as well as size
[16:39:23] <cradek> it depends
[16:39:31] <cradek> that's not answerable
[16:39:40] <cradek> you'll have to search in your location
[16:40:08] <nubcake> about to specify that right now, just getting the info together ^^
[16:40:53] <CaptHindsight> nubcake: will you be turning anything other than potatoes, carrots and other root vegetables?
[16:41:03] <The_Ball> I'm thinking of retrofitting a tiny watchmakers lathe with a beaglebone black as my next project. Could be a "cute" setup
[16:41:07] <Deejay> gn8
[16:41:22] <nubcake> CaptHindsight, i was thinking of aluminium and maybe steel
[16:42:32] <CaptHindsight> nubcake: where are you located? Country, state, planet etc
[16:42:51] <nubcake> Germany, Bavaria, Earth.. uhm. not sure about etc.
[16:43:49] <nubcake> 30-50cm spread (is it spread? max length of the working material)
[16:44:39] <nubcake> diameter of the working material around 10-15cm (more if it's not going to be too expensive)
[16:45:13] <CaptHindsight> nubcake: there are few from your region here earlier in the day, you might ask them
[16:45:38] <CaptHindsight> try 5-6 hours earlier
[16:45:42] <nubcake> CaptHindsight, will try, mostly missed them :'D
[16:46:16] <nubcake> CaptHindsight, that's gonna be difficult as i'm at work around that time. but i'll try to get a hold :)
[16:46:24] <CaptHindsight> they tend to use lots of ChinaCo parts
[16:46:42] <nubcake> are those of any use?
[16:46:59] <CaptHindsight> ChinaCo = parts from China
[16:47:09] <nubcake> yeah, i figured that ^^
[16:47:32] <nubcake> but are those parts (i guess the cheap ones) of any use at all, or should i better keep looking for something else?
[16:48:35] <SpeedEvil> Basically any machine tool is of some use.
[16:48:55] <SpeedEvil> How many cycles it will last, and what accuracies, and with what materials is the question.
[16:51:12] <CaptHindsight> https://wiki.hackerspaces.org/Bavaria check around and see what they have found
[16:51:18] <nubcake> Ok, well i don't have any numbers about that at all.. not planning to go for accuracy in the µ's just want something to start with, learn from and hopefully develop some kind of better understanding of it.
[16:51:53] <SpeedEvil> damn near anything will be quite useful to learn on.
[16:52:14] <nubcake> oh cool, didn't know about that page hackerspaces.org.. that's neat
[16:52:18] <nubcake> thanks for the link
[16:54:29] <CaptHindsight> https://www.youtube.com/watch?v=WhmP2IpJ8dc Virtual Lathe Simulator
[17:00:18] <nubcake> Says the Software cant be downloaded anymore
[18:00:32] <nubcake> good night everyone
[18:02:24] <The_Ball> anyone with a cnc lathe, do you know which way does the X axis move when you turn the MPG clockwise? I made it increment X as I thought that makes sense, but that is the opposite of what a manual lathe does
[18:03:23] <Tom_L> would depend which side the tooling is on i think
[18:03:46] <The_Ball> Standard "manual lathe" layout
[18:04:46] <Tom_L> CC head would be -X as -X would cut into the center
[18:05:16] <Tom_L> (i think)
[18:07:22] <JT-Shop> for a front tool lathe clockwise is + or toward you
[18:08:06] <The_Ball> Thanks
[18:08:34] <Tom_L> matches what i though as well
[18:17:31] <andypugh> I am pretty sure I reversed mine so as not to confuse matters. But my lathe has separate X and Z mpg wheels on the carriage, to feeling like a normal lathe matters a bit more.
[18:18:10] <The_Ball> that's what I was thinking, I'm also using two MPGs
[18:19:09] <DaViruz> http://i.imgur.com/L2QtU2c.png
[18:19:12] <DaViruz> this fellow is set up that way as well
[18:23:31] <zeeshan> where is skunkworks
[18:23:31] <zeeshan> =/
[18:24:36] <Tom_L> in the desert
[18:24:39] <zeeshan> hi
[18:24:41] <zeeshan> =P
[18:24:56] <Nick-Shop> JT - What's up with that card?
[18:25:48] <zeeshan> does anyone here have a complex setup using linuxcnc?
[18:25:51] <zeeshan> ie ethercat drives
[18:26:02] <zeeshan> where you're controlling the position loop on the drives
[18:26:05] <zeeshan> instead of linuxcnc
[18:27:30] <zeeshan> anyone got any videos of linuxcnc being used for highspeed machining?
[18:27:34] <zeeshan> 500~ ipm?
[18:29:37] <renesis> tom_l: i kind of wonder now
[18:29:54] <renesis> well actually, maybe not
[18:30:28] <renesis> my anecdotal evidense points to alot of their work being based out of nevada besides their palmdale place, but ya still desert
[18:31:58] <Tom_L> wonder?
[18:32:24] <Tom_L> you know he compiled some videos from ppl somewhere
[18:32:33] <zeeshan> tom! i know you know
[18:32:34] <zeeshan> answer me!!!!!!!!
[18:32:50] <Tom_L> what do you want to know?
[18:33:24] <zeeshan> videos of highspeed machining using linuxcnc
[18:33:31] <zeeshan> im also planning to buy my drives soon
[18:33:34] <zeeshan> i want to use more modern stuff
[18:33:41] <zeeshan> all the work stuff is ethernet based
[18:33:44] <zeeshan> i want to learn how it works
[18:33:47] <renesis> tom_l: i doubt they do anything very secret in palmdale anymore
[18:34:21] <Tom_L> https://www.youtube.com/watch?v=84iP10KShvY
[18:34:40] <Tom_L> you never know
[18:34:58] <zeeshan> thats far from highspeed machining
[18:35:04] <zeeshan> :P
[18:35:10] <zeeshan> thats just a circular pocket!
[18:35:25] <Tom_L> faster than yours
[18:35:29] <Tom_L> :)
[18:35:36] <zeeshan> hes going at 78ipm
[18:35:39] <zeeshan> i got videos at 120 ipm
[18:35:44] <zeeshan> and thats not even highspeed machining
[18:35:50] <zeeshan> im looking for 400-500 ipm range
[18:35:50] <Tom_L> my sherline will do that
[18:35:54] <Tom_L> i know
[18:35:56] <zeeshan> a lotta people say linuxcnc can do it
[18:35:59] <zeeshan> but ive never seen evidence
[18:36:00] <zeeshan> just theory
[18:36:47] <cradek> if you know what acceleration and velocity you want, set up the simulator accordingly and try it
[18:37:10] <cradek> you can plot anything you want about the motion with halscope
[18:37:20] <zeeshan> simulator isnt real world
[18:37:21] <zeeshan> :/
[18:37:50] <zeeshan> https://youtu.be/2fuYj4trEGg?t=73
[18:38:00] <zeeshan> something like that
[18:38:06] <cradek> you will know a lot more about linuxcnc's capabilities by measuring and studying them than by watching youtube videos
[18:38:25] <zeeshan> cradek: theory is one thing
[18:38:37] <zeeshan> visually seeing it getting done is another
[18:38:49] <renesis> well simulate it first and see if the software is capable
[18:38:52] <Tom_L> https://www.youtube.com/watch?v=uZtCJhwA5VI
[18:38:54] <renesis> then deal with the hardware
[18:38:58] <renesis> because free and fast
[18:39:10] <renesis> and more information than you have now
[18:39:19] <cradek> that's a super trivial kind of motion in that video
[18:39:27] <Tom_L> yeah
[18:39:30] <zeeshan> mine or toms
[18:39:37] <Tom_L> both probably
[18:39:42] <cradek> the one where the bro says "let's rock and roll"
[18:39:46] <zeeshan> haha
[18:39:49] <Tom_L> heh
[18:39:53] <Tom_L> no sound here
[18:39:55] <zeeshan> the guy is a dork
[18:40:00] <zeeshan> but i like him
[18:40:08] <Tom_L> typical geek
[18:40:13] <zeeshan> it says 800 ipm on the controller
[18:40:20] <zeeshan> but i dont think its actually doing 800 ipm
[18:40:22] <renesis> shrug, the full panel wood router i drove went like 400ipm with some ancient win xp based DOS looking software
[18:40:37] * Tom_L paints 800ipm on his sherline controller
[18:40:38] <zeeshan> renesis: not 400 ipm in straight lines
[18:40:40] <zeeshan> i mean using HSM
[18:40:45] <renesis> didnt slow down much doing tights arcs or reversals
[18:40:47] <zeeshan> ie usually many little lines
[18:40:50] <zeeshan> or many small arcs
[18:40:55] <zeeshan> thousands of em :P
[18:40:57] <renesis> right like splined arcs
[18:41:08] <cradek> the performance of that kind of gcode is precisely what you could measure in the simulator
[18:42:01] <zeeshan> simulation knows the lag between the drive and the computer?
[18:43:04] <cradek> brb
[18:44:05] <zeeshan> i feel like making some chips this weekend!
[18:44:17] * Tom_L just ate some
[18:45:56] <zeeshan> https://youtu.be/XoAgAy7RBGU?t=8
[18:45:58] <Tom_L> https://m.reddit.com/r/EngineeringPorn/comments/2o0qsy/high_speed_machining_operations_in_a_cnc_tapping/
[18:46:00] <zeeshan> i wish i wrote down the speed in this shit
[18:46:02] <Tom_L> that says linuxcnc
[18:46:03] <zeeshan> i think this was 120 ipm
[18:46:17] <zeeshan> im gonna try not using the keep tool down option
[18:46:23] <zeeshan> going to try retract to z
[18:46:28] <zeeshan> cause i think keep tool down option is slower
[18:47:04] <Tom_L> High speed machining operations in a CNC tapping center ... LinuxCNC running an analog servo interface board connected directly to all the existing drives.
[18:47:30] <zeeshan> youre the best
[18:47:31] <zeeshan> :-)
[18:47:47] <zeeshan> i dont think thats linuxcnc
[18:47:49] <zeeshan> ive seen this before
[18:47:51] <zeeshan> its a brother machine
[18:47:54] <Tom_L> says it is
[18:47:54] <zeeshan> demo part
[18:48:17] <zeeshan> https://www.youtube.com/watch?v=-fcWdMVVbEs
[18:48:19] <zeeshan> its lieing
[18:49:09] <zeeshan> if you read the posts
[18:49:13] <zeeshan> hes talking about a machine hes gettin
[18:49:22] <Tom_L> i did
[18:49:34] <zeeshan> i cant be the only one with my lousy 120 ipm videos!
[18:50:44] <Tom_L> i don't think the pc or link would be the bottleneck
[18:51:05] <zeeshan> Tom_L: help me find an ethernet setup
[18:51:09] <zeeshan> i want to use emerson drives
[18:51:36] <cradek> if you care about getting as fast a servo cycle time as possible, you want pci
[18:51:52] <cradek> at 800ipm the machine moves .013inch/ms
[18:52:14] <zeeshan> cradek: i am not doubting linuxcnc can do it
[18:52:16] <BeachBumPete> GOD thats freaking beautiful ;)
[18:52:18] <cradek> might be better to run at 3-4kHz if you go that fast
[18:52:31] <zeeshan> it would be niceto find a video that demonstrates it in real life to others
[18:52:34] <zeeshan> i was talking to a coworker at work
[18:52:38] <zeeshan> and i couldnt show him shit
[18:52:39] <zeeshan> =/
[18:52:46] <cradek> I mean if you want to *cut* at 800ipm
[18:52:53] <zeeshan> you really do
[18:52:53] <Tom_L> build one then show him
[18:52:57] <cradek> lots of machines can rapid that fast, and 1kHz is just fine
[18:52:57] <zeeshan> in aluminum
[18:53:07] <zeeshan> youre right
[18:53:17] <Tom_L> cutting or rapid isn't up to the pc
[18:53:18] <zeeshan> but i havent seen them take curves and real geometry at those speeds
[18:53:27] <cradek> Tom_L: exactly
[18:53:42] <cradek> zeeshan: yep, and that's what you could simulate
[18:53:46] <cradek> :-)
[18:54:22] <cradek> well it can be a factor. if you had linear motors that wanted 10kHz update you'd have to be very careful about your hardware
[18:54:53] <cradek> but for normal machine tools, even fast ones, the PC has an easy job
[18:55:42] <zeeshan> have you seen any retrofits where people are controlling the position loop off the drives?
[18:55:45] <zeeshan> instead of through linuxcnc?
[18:56:00] <cradek> all step/dir servo drives do that
[18:56:02] <zeeshan> (i really do not see the advantage of doing that)
[18:56:10] <cradek> nah, I don't either
[18:56:17] <zeeshan> because now you'd need to tune the drives using their propietary software
[18:56:27] <zeeshan> or some knobs
[18:56:33] <malcom2073_> heh knobs
[18:56:41] <zeeshan> frigging amc is knobs :P
[18:56:43] <cradek> even velocity mode amps have knobs to tune
[18:56:52] <cradek> (if you're lucky)
[18:56:54] <zeeshan> yea my amc is tuned using knobs
[18:56:57] <zeeshan> pots
[18:57:02] <cradek> if you're unlucky they have software for windows 3.1
[18:57:08] <zeeshan> haha
[18:57:18] <zeeshan> i REALLY want to try modern drives
[18:57:21] <zeeshan> just for learning
[18:57:29] <zeeshan> when i go see our machines
[18:57:38] <cradek> my hnc has amps that require you unsolder and replace resistors
[18:57:41] <zeeshan> its stuf ive never seen
[18:57:44] <zeeshan> haha
[18:57:44] <cradek> they're up on little posts so easy to find
[18:57:50] <zeeshan> that was like the bosch tr15
[18:57:54] <cradek> it works fine, much better than software
[18:58:15] <zeeshan> correct me if im wrong
[18:58:22] <zeeshan> wouldn't it be better to tune in software?
[18:58:28] <zeeshan> cause the tune might change over time?
[18:58:40] <cradek> well the amps were made in '78
[18:58:51] <cradek> software doesn't last like hardware does
[18:59:27] <cradek> so... "it depends"
[18:59:35] <BeachBumPete> I like those HNC's
[18:59:48] <malcom2073_> So funny thing, at work, we actually snapshot software when we take data logs of stuff, to ensure we can always view the data
[18:59:52] <Tom_L> upi dpm
[19:00:11] * Tom_L moves hands to the right
[19:00:20] <Tom_L> you don't still have windows 3.1???
[19:00:33] <malcom2073_> *left*
[19:00:36] <Tom_L> sry
[19:00:40] <Tom_L> other right
[19:00:45] <malcom2073_> I was looking at my keyboard... trying damn hard to figure out what yo uwere trying to say :-D
[19:01:04] <zeeshan> Control Techniques' SM-Applications and SM-EZ Motion option modules enable high performance motion / positioning controllers to be integrated within the drive. The position control loops operate at high speed and are synchronized to the drives internal current and speed loop, eliminating delays, which maximizes control performance.
[19:01:08] <Tom_L> i lost feeling in my index finger so i miss the keys once in a while now
[19:01:14] <zeeshan> this is one of the first things you read for emerson drives
[19:01:26] <zeeshan> it makes it sound like using a computer to do the position loop is a bad thing
[19:01:29] <BeachBumPete> thats the same company that made the original control in my Cinci
[19:01:35] <zeeshan> i highly doubt these things are running linear motors.
[19:01:47] <zeeshan> who
[19:01:51] <zeeshan> control techniques?
[19:01:54] <BeachBumPete> yeah
[19:01:58] <malcom2073_> Using the computer to do the position loop *is* a bad thing, in comparison to a totally integrated system
[19:02:06] <zeeshan> why
[19:02:07] <malcom2073_> Where teh drives do the position loop, but they talk very closely to the computer
[19:02:11] <malcom2073_> Speed
[19:02:17] <zeeshan> but cradek just said above
[19:02:21] <zeeshan> the computer is more than adequare
[19:02:24] <zeeshan> for like 800 ipm
[19:02:26] <malcom2073_> It is more than adequate
[19:02:27] <zeeshan> or even more
[19:02:57] <zeeshan> then using a drive to do a positional loop sounds like a gimmick no?
[19:03:03] <malcom2073_> When you have a hammer, every problem looks like a nail. Why try to make smarter drives, when the computer does all the thinking just fine?
[19:03:07] <Tom_L> get a 3-5hp 20k spindle and you can run just about any speed you can
[19:03:46] <zeeshan> malcom2073_: thats correct
[19:03:49] <zeeshan> so its a gimmick then!
[19:03:56] <malcom2073_> zeeshan It's progress
[19:04:14] <zeeshan> im looking at it from an economical perpsective
[19:04:28] <zeeshan> if a comp can do the speed you want, then why do you need something much more expensive to do it for you
[19:04:29] <Tom_L> did you sell em on your software yet?
[19:04:31] <zeeshan> i dont see the advantage
[19:04:42] <zeeshan> Tom_L: lol im not sellng!
[19:04:43] <BeachBumPete> damn I am glad its Friday ;)
[19:04:44] <zeeshan> im advising!
[19:04:46] <malcom2073_> zeeshan: Because it can't do *more* speed than you want?
[19:04:55] <Tom_L> call it what you want
[19:05:02] <zeeshan> malcom2073_: yes, but the only way i'll get to do more speed
[19:05:11] <zeeshan> is going to linear slideways
[19:05:15] <malcom2073_> Or a faster position loop?
[19:05:16] <zeeshan> and prolly some very high end servos
[19:05:25] <zeeshan> i'd think the servo would be the limitation
[19:05:42] <zeeshan> malcom2073_: look at it from my perspective
[19:05:51] <zeeshan> my lathe from factory was supposed to do 600 ipm
[19:05:54] <zeeshan> or 800
[19:05:57] <zeeshan> i forget
[19:05:58] <malcom2073_> zeeshan: I'm just trying to play devils advocate
[19:06:04] <zeeshan> i'm trying to pick a drive that'll work
[19:06:10] <zeeshan> and push the servos to their limit
[19:06:26] <zeeshan> i want to simplify wiring
[19:06:34] <BeachBumPete> is this for your big turning center?
[19:06:38] <zeeshan> yes
[19:06:45] <BeachBumPete> kickass
[19:06:51] <malcom2073_> Does linuxcnc support things like elmo controllers that close the loop in the controller?
[19:06:56] <malcom2073_> like over ethercat or can?
[19:07:15] <malcom2073_> I mean, like you said: if it ain't broke, don't fix it
[19:07:17] <zeeshan> i'm a noob
[19:07:19] <zeeshan> listen
[19:07:20] <malcom2073_> use normal +/-10v servo drives
[19:07:26] <zeeshan> i don't even know what the point of ethercat is
[19:07:26] <malcom2073_> They work damn well in many many many cases
[19:07:32] <malcom2073_> Ugh, I fucking hate ethercat
[19:07:34] <zeeshan> do you use it when you're trying to control position in the drive?
[19:07:35] <malcom2073_> I mean... *really* hate it
[19:07:47] <malcom2073_> You use it when you want to be annoyed as shit
[19:07:51] <zeeshan> no im serious
[19:07:54] <zeeshan> thats all i see in our machines
[19:08:04] <zeeshan> some ethernet cables doing to the drive
[19:08:05] <malcom2073_> It's low jitter communications over ethernet, except not using *actual* ethernet
[19:08:05] <zeeshan> and some power wires
[19:08:07] <zeeshan> its nice and clean
[19:08:12] <malcom2073_> Much lower jitter than ethernet
[19:08:17] <zeeshan> yes
[19:08:22] <zeeshan> but why do you need lower jitter?
[19:08:29] <zeeshan> cause youre trying to do position on the drive?
[19:08:45] <malcom2073_> Or you're trying to do coordinated motion with two drives
[19:08:46] <zeeshan> and each drive can communicate with other drives at highspeeds
[19:08:48] <zeeshan> to figure out whats going on?
[19:08:55] <malcom2073_> They don't communicate with each other
[19:08:58] <malcom2073_> they communicate with the master
[19:10:04] <zeeshan> is the master like a computer?
[19:10:10] <malcom2073_> It can be, yes
[19:10:19] <malcom2073_> It can also be dedicated hardware
[19:10:19] <zeeshan> i dont absolutely get it
[19:10:19] <zeeshan> lol
[19:10:28] <zeeshan> why is it better than using analog
[19:10:29] <malcom2073_> Ok big example, we have robots that have 4 arms
[19:10:33] <malcom2073_> each arm has 7 motors (7 joints)
[19:10:43] <malcom2073_> Each motor has a drive on it
[19:11:15] <malcom2073_> Easiest way to wire and control is ethercat, since it's a bus. We can run a single ethercat cable down each arm, so we have 4 ethernet cables coming back, rather than 28 analog and encoder cable sets
[19:12:01] <zeeshan> so each arm goes to some sort of master?
[19:12:04] <zeeshan> er
[19:12:10] <zeeshan> each drive for each arm goes to a master
[19:12:13] <malcom2073_> Right, each arm goes to an ethernet port on our main control computer
[19:12:20] <zeeshan> and then one cable comes out from each arms' master?
[19:12:25] <malcom2073_> No, each arm has 7 motors. each motor has its own onboard driver
[19:12:38] <zeeshan> i dont see how you got 4 cables going
[19:12:43] <malcom2073_> Single ethernet cable goes up the arm, and each motor has two ports, input and output
[19:12:51] <malcom2073_> ethernet cable goes in one side, out the other, all the way up the arm
[19:12:58] <Tom_L> one for each arm
[19:12:58] <malcom2073_> So each arm only has 1 cable at the base
[19:13:00] <malcom2073_> Yeah
[19:13:03] <zeeshan> okay
[19:13:05] <zeeshan> so it's like a switch
[19:13:10] <malcom2073_> More like a bus
[19:13:12] <Tom_L> one cable controls a set of drives
[19:13:12] <malcom2073_> Because it is a bus
[19:13:20] <zeeshan> does each drive have an ip address
[19:13:21] <zeeshan> or something like that
[19:13:27] <malcom2073_> Nope
[19:13:32] <zeeshan> how do you send a packet
[19:13:34] <zeeshan> to a specific drive then
[19:13:36] <zeeshan> if they're all chained
[19:13:39] <malcom2073_> Each drive has an ID, but each drive on a "chain" sees every message
[19:13:43] <malcom2073_> but only responds to messages meant for them
[19:13:45] <Tom_L> probably has the drive in the packet
[19:13:51] <malcom2073_> Sorry yes, it has like an ip address
[19:13:56] <malcom2073_> but it's an ID, not an ip
[19:14:00] <Tom_L> or i2c of sorts
[19:14:05] <zeeshan> okay so one major advantage is
[19:14:08] <zeeshan> ease of wiring
[19:14:11] <zeeshan> and since less wiring
[19:14:15] <zeeshan> less wiring to diagnose in the future
[19:14:17] <zeeshan> that can be a huge thing
[19:14:17] <malcom2073_> Yes
[19:14:32] <malcom2073_> And, you can hook it to a single PC. No mesa daughterboard needed for controlling
[19:14:34] <malcom2073_> 28 motors, remember
[19:14:41] <malcom2073_> only needs 4 ethernet ports, no other special hardware
[19:15:11] <zeeshan> i do like the idea
[19:15:18] <zeeshan> of feeding the encoder for each motor to it's own drive
[19:15:23] <zeeshan> now you dont hajve a huge run of cable
[19:15:26] <zeeshan> going to the main computer
[19:15:31] <zeeshan> and having to deal with bullshit of noise
[19:15:44] <Tom_L> so you rely on the drive hardware to monitor it's position
[19:15:52] <malcom2073_> Yeah
[19:15:55] <Tom_L> does it send a packet back to the master to confirm position?
[19:15:57] <zeeshan> heres the main question
[19:16:05] <zeeshan> how does the master tell the x axis
[19:16:06] <zeeshan> to move 1"
[19:16:11] <malcom2073_> Tom_L: Yes, but not for control, only for confirmation
[19:16:23] <malcom2073_> zeeshan: Does that command invole more than one motor?
[19:16:26] <zeeshan> simplifying things massively
[19:16:26] <malcom2073_> Or just one motor?
[19:16:29] <Tom_L> like a checksum of sorts
[19:16:36] <zeeshan> does it go like IP ADDRESS OF X drive, move 1"
[19:16:46] <zeeshan> its a one way coimmand
[19:16:48] <zeeshan> rather than two way
[19:16:55] <Tom_L> zeeshan wire it with sliding windows kermit :)
[19:17:27] <malcom2073_> zeeshan: Yep. You say "go to position X with a speed of Y", and it reports back as it goes
[19:17:57] <zeeshan> it reports back in fine increments?
[19:18:05] <malcom2073_> In whatever increments you tell it to
[19:18:10] <zeeshan> not as fine increments as the drive is communicating directly to the motor
[19:18:10] <zeeshan> i'm sure
[19:18:12] <Tom_L> who accounts for accel / decel?
[19:18:18] <malcom2073_> I'm sure
[19:18:21] <malcom2073_> Tom_L: You set accel/decel
[19:18:23] <Tom_L> is that built in the drive controller
[19:18:25] <malcom2073_> Either beforehand, or in the move command
[19:18:40] <malcom2073_> These are Elmo drives, so you have complete control over the motion profiles
[19:18:58] <zeeshan> what if its something ridiculus for acceleration
[19:19:03] <zeeshan> that the motor can't physically achieve
[19:19:04] <zeeshan> what happens then?
[19:19:14] <zeeshan> (and youre commanding it from the master)
[19:19:19] <malcom2073_> The motor errors out, and sends a joint tracking error back to the master
[19:19:22] <malcom2073_> It stops moving
[19:19:23] <Tom_L> you should know better
[19:19:27] <zeeshan> haha
[19:19:29] <malcom2073_> Just like linuxcnc does :)
[19:19:33] <zeeshan> okay so it's a very robust system
[19:19:42] <malcom2073_> Elmos are the pinacle of robustness
[19:19:43] <malcom2073_> imo
[19:19:47] <zeeshan> i can now see why i see it being used everywhere
[19:19:50] <malcom2073_> We run a 250hz control loop, which means we send commands to each motor in 250hz increments. So if we want to move 1 inch in 1 second, we send 250 1/250th increment move messages.
[19:19:56] <malcom2073_> on the master
[19:19:58] <zeeshan> seriously, i've walked to a buinch of automation companies for interviews
[19:20:00] <zeeshan> i mostly see emerson drives
[19:20:07] <zeeshan> (control techniques)
[19:20:11] <malcom2073_> Tbh, my opinion means shit
[19:20:17] <malcom2073_> I've only ever used elmos, but I've only ever worked for two companies
[19:20:22] <zeeshan> no, you have a good insight into it
[19:20:23] <malcom2073_> So may just be their preference
[19:20:29] <zeeshan> only a person who's used it has a good detailed insight like this
[19:20:30] <zeeshan> :P
[19:20:37] <malcom2073_> but I like them, other than the stupid ethercat crap
[19:20:43] <Tom_L> http://www.elmomc.com/products/servo-drives.htm
[19:20:44] <malcom2073_> I hate ethercat because linux's implementation is shit.
[19:21:05] <zeeshan> now the question is money
[19:21:10] <malcom2073_> Haha, on ebay? Not terrible :-P
[19:21:10] <zeeshan> simplfiying wire for much more cost
[19:21:11] <zeeshan> =/
[19:21:16] <malcom2073_> You do NOT want to do ethercat
[19:21:24] <zeeshan> what would you recommend
[19:21:30] <zeeshan> for something that use some sort of fieldbus
[19:21:36] <malcom2073_> That's tough. I have zero hobbiest level experience with servos
[19:21:43] <Tom_L> can?
[19:21:49] <malcom2073_> I love fieldbus... but I'm not sure it's good for linuxcnc level of motion control
[19:22:06] <malcom2073_> I don't *actually* know what the limit of our coordinated motion is... or if it's good enough for machining operations
[19:22:17] <Tom_L> dude i know using lcnc was using can
[19:22:18] <malcom2073_> we have robotic arms, they're not precision machines. They have play and flex
[19:22:29] <Tom_L> builds forestry equipment
[19:23:13] <Tom_L> zee's a speed freak though...
[19:23:28] <malcom2073_> My servos, I'm planning on doing +/-10v analog control
[19:23:35] <zeeshan> Tom_L: i'm not a speedfreak
[19:23:39] <zeeshan> if you're not using hsm these days
[19:23:40] <malcom2073_> Gonna get some of sync's servo drives at some point
[19:23:48] <zeeshan> you're not making as money as you should be
[19:24:15] <zeeshan> it's pretty clear to me hsm is the technique to use when you have a shit load of chips to make
[19:24:21] <Tom_L> do they have a free version?
[19:24:21] <tiwake> zeeshan: isnt that the case for most people in here?
[19:24:42] <zeeshan> i'm not saying hsm the software
[19:24:45] <zeeshan> i mean highspeed machining
[19:25:07] <zeeshan> mastercam and inventor hsm are pretty much the same for highspeed machining
[19:25:19] <zeeshan> and yes 2.5axis is free
[19:25:19] <Tom_L> loads are high
[19:25:22] <zeeshan> and if y ou have fusion 360
[19:25:26] <Tom_L> increasing wear on equipment
[19:25:27] <zeeshan> 3d is part of it
[19:25:30] <Tom_L> increasing downtime
[19:25:50] <zeeshan> tell me why you think you're have more wear on the equipment
[19:25:58] <zeeshan> because of the movements?
[19:26:01] <Tom_L> sure
[19:26:07] <zeeshan> sure i agree
[19:26:09] <zeeshan> but the cutting forces are lower
[19:26:11] <zeeshan> not higher
[19:26:42] <zeeshan> i was reading an article by schulz
[19:26:44] <Tom_L> they probably blow spindles out quicker too
[19:26:54] <malcom2073_> Job shops, gotta get the job done
[19:26:55] <zeeshan> a lot of shops have been using high speed machining techniques since the 80s
[19:27:01] <zeeshan> noway
[19:27:04] <zeeshan> the spindle load is much lower
[19:27:13] <malcom2073_> How so? Taking lighter cuts?
[19:27:16] <Tom_L> what sort of rpm?
[19:27:17] <zeeshan> Tom_L: watch this video
[19:27:24] <zeeshan> and look at the graph in the background
[19:27:26] <zeeshan> of the cutting forces
[19:27:38] <zeeshan> remember this video only shows 1/2 the advantages
[19:27:50] <zeeshan> https://www.youtube.com/watch?v=-wHXd25N3Ns
[19:27:56] <zeeshan> nly need to see the first 3 1/2 mins of it
[19:28:16] <malcom2073_> Oooo 2 axis head
[19:28:18] <Tom_L> no sound here
[19:28:22] <malcom2073_> I want to do that on my big router when I build it
[19:28:23] <zeeshan> why
[19:28:25] <zeeshan> you need sound for this
[19:30:06] <malcom2073_> can fusion360 handle a head like that on the free version?
[19:30:07] <Tom_L> they're using a high helix cutter too
[19:30:19] <Tom_L> malcom2073_ i doubt it
[19:30:29] <zeeshan> head like what
[19:30:34] <Tom_L> i'd be surprised if it did
[19:30:44] <malcom2073_> zeeshan: a 2 axis head
[19:30:50] <zeeshan> wtf is a 2 axis head!!!
[19:30:59] <zeeshan> you mean a 3 axis mill?
[19:31:05] <Tom_L> like a a b cradle only backwards
[19:31:16] <zeeshan> it has 3 +2 machining
[19:31:23] <malcom2073_> zeeshan: at the beginning of that video you linked
[19:31:26] <zeeshan> lemme see
[19:31:39] <zeeshan> yea
[19:31:40] <zeeshan> you can do that
[19:31:46] <zeeshan> wait
[19:31:50] <zeeshan> thats a flow line cut
[19:31:51] <zeeshan> no you cant
[19:31:53] <zeeshan> thats a 5 axis tool path
[19:33:19] <Tom_L> http://www.nccs.com/
[19:33:44] <zeeshan> why you post that!
[19:34:08] <Tom_L> local shop was considering it
[19:34:09] <malcom2073_> heh
[19:34:20] <zeeshan> honestly if youre just a job shop
[19:34:24] <zeeshan> pay the money for fusion 360
[19:34:25] <Tom_L> catia will do that too
[19:35:57] <zeeshan> fusion 360 does 3d tool paths and turning
[19:36:00] <zeeshan> (no mill turn)
[19:36:11] <zeeshan> 30 bux a month
[19:36:13] <zeeshan> cant beat it
[19:36:13] <zeeshan> :P
[19:36:16] <malcom2073_> heh
[19:36:20] <zeeshan> (trust me i hate the interface of fusion 360)
[19:36:25] <zeeshan> but i'd force myself to learn it
[19:36:30] <zeeshan> if i was trying to save money
[19:36:54] <zeeshan> it kind of pisses me of actually
[19:37:06] <zeeshan> work paid money for inventor pro licenses
[19:37:07] <zeeshan> many of them
[19:37:13] <zeeshan> you can only down 2.5 axis for free
[19:37:19] <zeeshan> none of the 3d tool paths are included.
[19:37:28] <zeeshan> fusion 360 is also included in our license
[19:37:29] <Tom_L> figures
[19:37:30] <malcom2073_> Hah
[19:37:35] <zeeshan> so i have to open that POS
[19:37:39] <zeeshan> to do 3d programming
[19:37:43] <Tom_L> 2.5 d is pretty easy to find cheap
[19:37:46] <zeeshan> makes zero sense to me.
[19:37:49] <malcom2073_> I'm switching jobs, so I'm losing access to inventor and solidworks
[19:38:00] <sync> malcom2073_: do it nao
[19:38:18] <zeeshan> im going to be sticking to solidworks at home
[19:38:19] <malcom2073_> sync: no monies for that atm... and I should probably build the actual machine before I buy drives for it :-P
[19:38:21] <zeeshan> but im thinking of buying hsmworks
[19:39:03] <malcom2073_> sync: I'm going to harp on you to get BISS encoder reading working once I do hehe
[19:39:25] <zeeshan> malcom2073_: im looking at the elmo drives
[19:39:34] <malcom2073_> zeeshan: I got a couple of smaller ones on ebay for like, $40
[19:39:42] <zeeshan> can you tell me what models i should be looking for
[19:39:44] <malcom2073_> Used them when playing around with my DC servos
[19:39:45] <zeeshan> i believe i need 200V
[19:39:48] <zeeshan> and 3kW
[19:39:51] <malcom2073_> Ouch
[19:39:54] <malcom2073_> that's *really* high power
[19:40:11] <zeeshan> yea the lathe has some big motors
[19:40:14] <malcom2073_> yeah
[19:40:14] <zeeshan> the main spindle is 20hp
[19:40:24] <zeeshan> but im planning to decrease that to 10hp
[19:40:27] <zeeshan> not enough power
[19:40:28] <zeeshan> )
[19:40:28] <Tom_L> don't run the microwave when you fire it up
[19:40:29] <zeeshan> :)
[19:40:47] <malcom2073_> https://github.com/rene-dev/stmbl
[19:40:55] <malcom2073_> up to 1kw, I've heard rumor you can get higher with some modifications
[19:41:50] <zeeshan> cant take chances
[19:41:53] <zeeshan> need to know for sure!
[19:42:39] <zeeshan> Tom_L: i forgot to tell you
[19:42:47] <zeeshan> remember how i was being made fun of for running a 100A breaker?
[19:42:55] <zeeshan> for the mill
[19:43:08] <malcom2073_> Did you blow it?
[19:43:12] <zeeshan> no
[19:43:15] <zeeshan> i measured the current
[19:43:21] <zeeshan> when doing serious cutting on steel
[19:43:28] <zeeshan> it peaks around 70A
[19:43:32] <malcom2073_> Haha
[19:43:32] <zeeshan> peak not continuous
[19:43:39] <zeeshan> most of the time is 30A
[19:43:39] <zeeshan> or so
[19:44:08] <sync> zeeshan: use our drives
[19:44:14] <zeeshan> no
[19:44:16] <zeeshan> :P
[19:44:27] <sync> why not
[19:44:35] <zeeshan> need to buy something with support
[19:44:41] <tiwake> I think most electric motors are rated at peak twice or so the power rating they are for continuous power... for 1/79th of a second? 1/49th?
[19:44:44] <sync> we'll support you
[19:45:03] <sync> and it is not like you can't figure shit out yourself, it is opensores
[19:45:10] <tiwake> not twice, maybe +1/3
[19:45:12] <malcom2073_> opensores!
[19:45:22] <zeeshan> f opensores
[19:45:25] <zeeshan> :]
[19:45:28] * zeeshan hijdes
[19:45:38] <sync> tiwake: you usually can run 300% torque for a while
[19:46:46] <tiwake> bleh I'm tired
[19:46:47] <zeeshan> sync: got a website for the drives?
[19:47:26] <zeeshan> tiwake: want real world #s
[19:47:29] <zeeshan> you'll get them anyway!
[19:48:11] * zeeshan digs datasheet
[19:48:12] <tiwake> zeeshan: real world numbers?
[19:48:42] <sync> zeeshan: malcom2073_ already linked it :P
[19:49:56] <zeeshan> yes, my xy mill servos have 51A peak current rating
[19:50:15] <zeeshan> 7.0A continuous current rating
[19:50:50] <zeeshan> i think the twice the rating rule of thing is for ac motors
[19:50:55] <zeeshan> but i'm not sure
[19:51:06] <zeeshan> sync i dont see
[19:51:37] <tiwake> zeeshan: most real world numbers are not really hard stops... ex: overclocking processors... it just depends on what you can get away with
[19:51:45] <zeeshan> yes
[19:51:54] <zeeshan> i know im not even close to running my motors hard enough
[19:52:01] <zeeshan> cause after a beating chip removal
[19:52:09] <zeeshan> they're warm to touch
[19:52:12] <zeeshan> not blazing hot :P
[19:52:26] <sync> https://github.com/rene-dev/stmbl zeeshan
[19:52:29] <zeeshan> need to get lathe running
[19:52:29] <tiwake> zeeshan: I work in the machine shop of an electric motor repair shop :P
[19:52:34] <zeeshan> then need to upgrade drives for mill
[19:52:46] <zeeshan> tiwake: hook me up!
[19:52:58] <tiwake> zeeshan: texas, anywhere close?
[19:52:58] <zeeshan> sync jeez
[19:53:09] <zeeshan> only 3000 miles away :P
[19:53:20] <tiwake> then sorry
[19:53:23] <zeeshan> do you know where fort dodge is
[19:53:24] <zeeshan> in tx
[19:53:31] <tiwake> uh, no?
[19:53:32] <zeeshan> i fly to different plants for work
[19:53:33] <sync> zeeshan: where is your problem?
[19:53:46] <zeeshan> sync: i aint builind that myself!
[19:53:51] <sync> why not?
[19:53:55] <zeeshan> wait im confusing fort dodge iowa
[19:54:03] <sync> you can also buy assembled drives
[19:54:04] <malcom2073_> I saw stmbl somewhere for sale...
[19:54:06] <malcom2073_> where was that?
[19:54:09] <malcom2073_> I couldn't find a link
[19:54:39] <zeeshan> i meant sweetwater texas
[19:55:03] <zeeshan> or mcqueeny tx
[19:55:05] <zeeshan> =D
[19:55:43] <tiwake> zeeshan: its a 2 hour drive from me
[19:55:46] <tiwake> evidently
[19:55:51] <zeeshan> sync: no +/-10v
[19:55:52] <zeeshan> fail
[19:56:11] <sync> nobody needs 10V
[19:56:21] <malcom2073_> zeeshan: Smart serial!
[19:56:22] <zeeshan> more voltage
[19:56:27] <zeeshan> power
[19:56:28] <zeeshan> yeaaaa
[19:56:45] <zeeshan> malcom2073_: i briefly searched google for ethercat support for linuxcnc
[19:56:48] <zeeshan> sounds like a whole lot of bs
[19:56:55] <sync> it works™
[19:57:11] <sync> zeeshan: we run straight sserial, a lot better than analog
[19:57:39] <zeeshan> i thought smartserial
[19:57:44] <sync> yes
[19:57:46] <sync> =sserial
[19:57:52] <zeeshan> was when you wanna put a daughtercard near a bunch of sensors
[19:58:00] <zeeshan> then run a massive serial cable back to the main card
[19:59:04] <sync> yeah, that is the current setup but the next one will just use ethernet
[19:59:58] <malcom2073_> so what, you connect every drive to a switch then back to the main pc?
[20:00:49] <zeeshan> honestly
[20:00:52] <zeeshan> since the lathe is so big
[20:01:01] <zeeshan> if you can do that, that would be super useful for me
[20:01:16] <zeeshan> im planning to keep the computer and all that crap inside the control panel
[20:01:20] <zeeshan> which has limited space
[20:01:29] <sync> nah malcom2073_, we have our own multiplexer
[20:01:32] <zeeshan> but i can put a big ass box bside the machine (about 15 feet away)
[20:01:41] <zeeshan> where all those servo crap can go
[20:01:44] <sync> as currently the mesa card we use is just an ethernet -> rs422 interface
[20:01:47] <malcom2073_> sync: So daisy chained?
[20:02:07] <malcom2073_> Oh multiplexer, so you're replacing the mesa
[20:02:17] <sync> yeah
[20:02:28] <sync> zeeshan: should be no problem
[20:11:01] <zeeshan> who else is doing a retrofit this winter?
[20:11:01] <zeeshan> :D
[20:11:09] <zeeshan> BeachBumPete: ?!?
[20:11:23] <gregcnc> i should finish the little emco
[20:12:23] <BeachBumPete> yeah
[20:12:34] <zeeshan> BeachBumPete: what drives did you go with
[20:12:44] <rene-dev> sync malcom2073_ zeeshan
https://www.youtube.com/watch?v=5CKMrOy0ZXk
[20:13:48] <BeachBumPete> for the new lathe I am using the ones from DMM
[20:13:49] <malcom2073_> rene-dev: +1
[20:14:08] <zeeshan> 320 ipm is good
[20:14:10] <zeeshan> lets see at 800!
[20:14:24] <Tom_L> hmm come to think of it i've got a couple sserial boards
[20:15:04] <rene-dev> 7i92 sserial bob for stmbl
https://www.dropbox.com/s/8g6ydjeaofeae8w/2016-10-17%2018.34.17.jpg?dl=0
[20:16:56] <Tom_L> zeeshan, still got your board but it's in a box now
[20:17:04] <zeeshan> ebay it
[20:17:10] <zeeshan> when things go in boxes
[20:17:11] <Tom_L> i'll keep it
[20:17:15] <zeeshan> they never come out
[20:17:15] <zeeshan> ;D
[20:17:44] <Tom_L> should have a spare 7i47 too
[20:19:22] <Tom_L> 7i90 is toast
[20:20:01] <Tom_L> 7i71 7i84
[20:20:10] <Tom_L> hmm
[20:20:24] <Tom_L> 6i24
[20:20:43] <Tom_L> that's a pcie
[20:21:12] <Tom_L> just need a good mill to put it on
[20:22:44] <zeeshan> anyone here ship a lot of things?
[20:23:03] <Tom_L> not anymore
[20:23:07] <BeachBumPete> I was shipping a lot of rails ;)
[20:23:21] <Tom_L> hmm, new 7i90 i forgot about
[20:24:30] <zeeshan> http://www.ebay.com/itm/NAKAMURA-TMC3-CNC-LATHE-PARTS-LIST-CATALOG-MANUAL-BOOK-/162170573325?hash=item25c21e920d
[20:24:32] <zeeshan> what do you guys see for price
[20:24:33] <zeeshan> for this
[20:24:36] <zeeshan> for shipping
[20:25:08] <Tom_L> not 12 bux
[20:25:17] <Tom_L> but anymore who knows
[20:25:20] <BeachBumPete> I was thinking ten
[20:25:28] <zeeshan> huh
[20:25:37] <Tom_L> ups just went up 10 bux on one i get alot of
[20:25:43] <Tom_L> just because it's long
[20:38:47] <rene-dev> zeeshan 0-10v is really limited in resolution
[21:05:07] <MacGalempsy> yo
[21:06:13] <BeachBumPete> Hello Mac
[21:07:14] <MacGalempsy> Heya Pete. anything new?
[21:07:28] <BeachBumPete> new house?
[21:07:33] <BeachBumPete> hehe
[21:07:41] <MacGalempsy> old news zzz
[21:07:47] <BeachBumPete> sorry
[21:07:55] <MacGalempsy> any cnc action this week?
[21:08:11] <BeachBumPete> my machine is now on its leveling pods and I am working on getting all the wiring hooked back up so I can get it powered up...
[21:08:27] <MacGalempsy> sweetness
[21:09:03] <BeachBumPete> the plan was this week to work each evening but honestly it has been a crazy work week and when I got home I was too tired to do much for the most part
[21:09:20] <MacGalempsy> heh. i hear that.
[21:09:54] <MacGalempsy> https://flic.kr/p/NspVq8
[21:09:56] <BeachBumPete> I did do some yesterday and tuesday tho. I plan to sleep in a bit and get working on it
[21:10:10] <MacGalempsy> oops wrong flik
[21:10:12] <BeachBumPete> did you pour it I guess?
[21:10:44] <MacGalempsy> https://flic.kr/p/NcEjw9
[21:11:07] <MacGalempsy> yeah. its sitting with a 400w lightbulb on a dimmer switch
[21:11:34] <BeachBumPete> so this is to cure it?
[21:12:17] <MacGalempsy> part of the process. i will bring it to 65°C and hold for 24hrs
[21:12:35] <BeachBumPete> sweet
[21:12:53] <MacGalempsy> then raise it to 150°C at 25deg per hr and hold for 3 days
[21:13:04] <MacGalempsy> or until it stops steaming
[21:13:21] <MacGalempsy> then fire time
[21:13:36] <BeachBumPete> awesome congrats
[21:14:23] <MacGalempsy> thanks. time to get to printing forms to cast into
[21:14:56] <BeachBumPete> that ought to be quite fun... I need to try my hand at 3d printing...
[21:15:55] <MacGalempsy> it took a dive today and the onboard fuse went out.
[21:16:22] <BeachBumPete> how much do you have in the project would you say?
[21:16:35] <MacGalempsy> which one :)
[21:16:49] <BeachBumPete> the hot one ;)
[21:17:21] <MacGalempsy> $8 for the drum and about $90 in cement
[21:17:49] <MacGalempsy> maybe another $20 in odds and sends.
[21:18:56] <MacGalempsy> next i will try to mix sandcasting sand
[21:19:11] <BeachBumPete> thats not bad at all really
[21:19:19] <BeachBumPete> how do you plan to heat it up?
[21:20:44] <MacGalempsy> the jet burner
https://flic.kr/p/M2ncwx
[21:21:09] <MacGalempsy> propane with compressor assist
[21:21:22] <BeachBumPete> sheeit
[21:21:46] <MacGalempsy> it will singe the hair from Satan's balls
[21:21:48] <BeachBumPete> looks like that will work juuuuust fine
[21:22:05] <BeachBumPete> ooh ouch
[21:22:49] <MacGalempsy> yeah. my buddy is welding up a foot operated stand
[21:23:44] <BeachBumPete> I have seen people make some neat stands for these things specifically with a cantilevered lid opener and whatnot
[21:24:22] <MacGalempsy> yeah. the thing should lift just the lid, or the entire mid and lid
[21:27:04] <MacGalempsy> it will hold a 4 liter crucible
[21:27:24] <BeachBumPete> sweet
[21:31:04] <MacGalempsy> i wonder how effeciently the molten Aluminum will disolve the ABS mold
[21:32:27] <BeachBumPete> dont you just use the mold to form the casting cavity?
[21:33:07] <MacGalempsy> i was going to pour right into it. make the wall .5mm thin
[21:33:48] <BeachBumPete> I know very little about this so whatever they normally do for the mold I suppose
[21:33:49] <MacGalempsy> it will require testing
[21:34:31] <MacGalempsy> imagine it as lost wax jewelry casting, but w plastic
[21:35:24] <BeachBumPete> sure I suppose that is possible but I have seen it done with the sand molding too
[21:35:33] <malcom2073_> I thought with ABS you typically burned it out before pouring?
[21:42:59] <MacGalempsy> just watched a video that showed him leaving it in.
[21:44:02] <MacGalempsy> his model was infilled, and there were spurts of the plastic melting. a shell would probably pour easier
[22:01:47] <zeeshan> anby one know why the fuck
[22:01:55] <zeeshan> kvirc won't let me double click links
[22:01:56] <zeeshan> ;[
[22:06:23] <MacGalempsy> junky software?
[22:07:27] <zeeshan> it used to let me
[22:07:30] <zeeshan> today it decided to stop
[22:08:55] <MacGalempsy> man, i added kapton tape to the printer today. ive never had such good prints
[22:17:41] <zeeshan> why
[22:51:21] <MacGalempsy> the adhesion between this abs and the tape is magic. no pulling up corners
[22:51:36] <XXCoder> yo
[22:51:41] <MacGalempsy> yo
[22:51:48] <XXCoder> yoyo is fun
[22:52:04] <MacGalempsy> yo
[22:52:50] <MacGalempsy> XXCoder: whats happening?
[22:53:04] <XXCoder> not much
[22:53:17] <XXCoder> just relaximng. been busy all day getting newer car
[22:53:29] <XXCoder> my van decided to basically die
[22:53:36] <MacGalempsy> what did you end up with?
[22:53:48] <XXCoder> ford focus 2012
[22:54:22] <MacGalempsy> cool. it should get good mileage, right?
[22:54:28] <XXCoder> yeah
[22:54:33] <XXCoder> 40 mpg supposely
[22:54:48] <MacGalempsy> time to trick it out :)
[22:54:53] <XXCoder> nah
[22:54:58] <XXCoder> just drive it till I get elio
[22:55:06] <XXCoder> then trade
[22:55:21] <MacGalempsy> ok
[22:56:12] <MacGalempsy> extra $$ for cnc by leaving it stock
[22:56:50] <XXCoder> lol
[22:58:14] <MacGalempsy> just put on LOTR, trying to keep an eye on the printer and furnace at the same time
[22:58:42] <XXCoder> just grow third eye for tv
[23:02:33] <MacGalempsy> i need a biocerebral chip
[23:05:19] <Tom_L> use oxy assist :)
[23:05:49] <MacGalempsy> ?
[23:05:56] <Tom_L> reading about your burner
[23:06:04] <Tom_L> catching up..
[23:08:48] <Tom_L> you don't burn the plastic out of the mold firstZ?
[23:09:34] <Tom_L> i wonder whether pla or abs would burn out better
[23:09:54] <MacGalempsy> well, im not sure, but want to experiment a little.
[23:11:05] <Tom_L> do you leave escape holes for the plastic?
[23:11:14] <MacGalempsy> the aluminum will be poured at 725°C and the abs melts at 230°C
[23:11:30] <Tom_L> yeah but it cools quick
[23:11:51] <Tom_L> just how quick i'm not sure
[23:12:55] <Tom_L> you didn't put any vent holes in the side of your burner?
[23:12:58] <Tom_L> iirc jt did
[23:13:07] <Tom_L> to suck air in too
[23:13:33] <MacGalempsy> the burner hooks up to compressed air
[23:14:54] <MacGalempsy> its touchy on the settings, i may try a smaller diameter insert
[23:39:13] <zeeshan> dont u guys sleep
[23:39:14] <zeeshan> :)
[23:39:44] <XXCoder> zeeshan: I sleep when you are not looking at me.
[23:39:48] <zeeshan> =]
[23:39:57] <XXCoder> unfortunately you dont seem to ever stop
[23:40:04] <XXCoder> (hi zeeshan!)
[23:40:38] <XXCoder> heh
[23:40:47] <XXCoder> well whats up there the z
[23:40:54] <XXCoder> last I heard youre at college and working
[23:41:01] <zeeshan> part time college :P
[23:41:04] <zeeshan> full time work
[23:41:39] <zeeshan> you?
[23:41:43] <zeeshan> hows the 3d printer goin
[23:41:46] <XXCoder> full time work heh
[23:41:50] <XXCoder> doing pretty good
[23:42:10] <XXCoder> having fun. just chilling today though, tired after all the busy stuff :P
[23:42:50] <zeeshan> :]
[23:42:55] <zeeshan> at work
[23:42:58] <zeeshan> do you guys use high speed machining paths
[23:43:04] <XXCoder> car buying sucks
[23:43:05] <zeeshan> or conventional
[23:43:10] <XXCoder> no idea lol
[23:43:17] <XXCoder> i dont do programming
[23:43:27] <XXCoder> your next project
https://youtu.be/DeNgIWj8ZM0 ;)
[23:44:11] <zeeshan> lolwtf
[23:44:43] <XXCoder> both, collectively, failed to equal that dog :P
