[03:02:11] <IchGucksLive> Hi from a Fog overloaded Germany
[09:48:41] <pythonirc101> has anyone used linuxcnc to do laser cutters?
[09:49:01] <cradek> sure
[09:49:15] <pythonirc101> cradek: can i build a machine so that it can act as a laser cutter and a cnc machine?
[09:49:32] <cradek> I don't know...
[09:49:41] <pythonirc101> cradek: how did you build one ?
[09:49:51] <cradek> I didn't
[09:49:57] <pythonirc101> cradek: you bought one?
[09:50:05] <cradek> no, I don't have any laser machine
[09:50:26] <pythonirc101> has anyone used linuxcnc to do laser cutters? - you said "sure"?
[09:50:35] <cradek> yes, lots of people have
[09:50:39] <archivist> what do you wantt to do with the laser, just burn or cut through
[09:50:43] <MacGalempsy> lcnc can do lasers?
[09:50:49] <archivist> yes
[09:50:54] <cradek> there are videos on youtube
[09:50:59] <MacGalempsy> NO WAY!
[09:51:03] <cradek> yes!
[09:51:16] <Roguish> pythonirc101: search youtube for linuxcnc to find the variety of applications.
[09:51:21] <pythonirc101> archivist: cut through/burn
[09:51:45] <pythonirc101> Seems like I'll need a lot of help. I decided to make a cnc/laser cutter using lcnc
[09:51:45] <MacGalempsy> es incredible!
[09:51:58] <archivist> burn on the same machine, burn through less sensible, you dont want to damage the base
[09:52:02] <cradek> rastering is tricky (although people have done it in various ways) but cutting an outline is not very different from machining
[09:52:23] <archivist> you could add a protective layer
[09:52:28] <pythonirc101> Around 36"x36" - what is the best place to buy frame/rail system for lcnc setup?
[09:52:53] <pythonirc101> So engraving is easier than laser cutting?
[09:52:55] <MacGalempsy> what country?
[09:52:57] <dioz> sup archivist ?
[09:52:57] <pythonirc101> us
[09:53:12] <CaptHindsight> depends on how well you understand how to build a machine and what location you are in
[09:53:39] <pythonirc101> CaptHindsight: I'm in eastern US. First thing is to find / find a frame
[09:53:42] <MacGalempsy> what kind of projects do you want to do with it
[09:54:01] <CaptHindsight> pythonirc101: do want a kit or just parts?
[09:54:03] <pythonirc101> MacGalempsy: Cut alum 20mm max. Cut acrylic - 1/4" max.
[09:54:11] <archivist> projects define the machine
[09:54:39] <MacGalempsy> 20mm is pretty think. acrylic is much easier
[09:54:41] <pythonirc101> CaptHindsight: I'd prefer to build one that is reliable and sturdy
[09:55:01] <pythonirc101> MacGalempsy: I was thinking of getting a 6090 - but i decided to build one instead of getting that
[09:55:18] <archivist> 20mm al, toys need not apply
[09:55:27] <MacGalempsy> ditto
[09:55:45] <MacGalempsy> maybe 2.0mm
[09:56:06] <pythonirc101> Frame recommendations?
[09:56:20] <pythonirc101> How does 80/20 website work? Do they have a good frame premade?
[09:56:21] <archivist> 20mm in 1mm bites on a light machine
[09:56:27] <pythonirc101> Also, any recommendations for good kits?
[09:56:46] <pythonirc101> archivist: I can absolutely live with that. And If I can afford it, I can buy better parts
[09:58:15] <MacGalempsy> one of the local guys made The Shark, which seemed ok. i think it was 50w co2
[09:58:23] <_methods> this must be that polymorhpate under another smurf account
[09:58:52] <pythonirc101> Perhaps there is an archive of this room somewhere, that I should read?
[09:59:02] <JT-Shop> zlog
[10:00:53] <archivist> _methods, I think there are two exceedingly similar people, the original was also in here yesterday remember he actually got a machine but then failed at the build
[10:01:41] <_methods> yeah interesting that this one shows up at the same time
[10:01:56] <_methods> coincidence....i think not
[10:02:02] <CaptHindsight> at least they didn't ask about welding zinc :p
[10:02:05] <pythonirc101> Maybe I should do some reading before I come here?
[10:02:32] <_methods> i huff galv fumes all the time
[10:02:48] <pythonirc101> http://www.ebay.com/itm/like/391539444553?catId=11700&item=391539444553&rmvSB=true - frame?
[10:02:58] <MacGalempsy> freinds dont let friends huff fumes....
[10:03:02] <MacGalempsy> ....without them
[10:03:05] <_methods> hahah
[10:03:55] <MacGalempsy> that case is huge
[10:04:26] <pythonirc101> MacGalempsy: any good?
[10:04:49] <MacGalempsy> you could get a whole laser setup instead?
[10:05:01] <pythonirc101> MacGalempsy: my main application is cutting alum/acrylic
[10:05:13] <_methods> lol
[10:05:13] <pythonirc101> laser cutter wont cut alum for me- at least not without costing an arm and leg?
[10:05:20] <archivist> those are very different materials
[10:05:39] <archivist> making what?
[10:05:47] <pythonirc101> archivist: I saw some videos about cutting acrylic using cnc setup - seems decent - rounded corners
[10:05:48] <MacGalempsy> why spend the money on that case when the laser is the most important thing?
[10:06:00] <pythonirc101> archivist: Mostly robotic experiments.
[10:06:24] <MacGalempsy> multiple passes with a galvo?
[10:06:25] <pythonirc101> MacGalempsy: it is not. Aluminium is more important
[10:07:28] <MacGalempsy> you should plan on 2 machines
[10:07:41] <CaptHindsight> a galvo is s bit to complex in this instance, you have to crawl before you run
[10:07:42] <pythonirc101> MacGalempsy: Then buy a cheap laser cutter and spend on the cnc
[10:07:43] <MacGalempsy> a router and a laser
[10:09:09] <pythonirc101> MacGalempsy: http://www.ebay.com/itm/High-Precise-40W-CO2-Laser-Engraving-Cutting-Machine-Engraver-Cutter-USB-Port-/201485085366?hash=item2ee9726ab6:g:6JoAAOSwfZ1WbnLw - something cheap
[10:09:39] <CaptHindsight> turn key system or many hours of the same questions in here with poor results
[10:09:51] <MacGalempsy> that is a common onen but i think the BOB needs to be swapped out for linuxcnc
[10:10:16] <pythonirc101> MacGalempsy: yes, I've heard of the board swap on those machines
[10:10:37] <CaptHindsight> even the cheapco engravers need tweaks to operate properly
[10:11:17] <pythonirc101> is there a cnc kit i could buy, that i can make work? and is decent?
[10:11:55] <archivist> are you expecting us to have bought and tried all teh shite out there
[10:12:07] <MacGalempsy> a Haas VSS
[10:12:19] <_methods> looking forward to the same questions being repeated for 3 months again
[10:12:30] <pythonirc101> archivist: "CaptHindsight: pythonirc101: do want a kit or just parts?"
[10:13:08] <MacGalempsy> lol. _methods: all questions must be asked in Esperanto
[10:13:16] <_methods> hehe
[10:13:27] <_methods> repeatedly?

[10:20:38] <gregcnc> if it has a change gear set, maybe reasonable
[10:21:49] <CaptHindsight> http://madison.craigslist.org/tls/5801437844.html $1200 or best
[10:24:38] <MacGalempsy> gregcnc: that kitamira looks awesome
[10:25:09] <CaptHindsight> http://appleton.craigslist.org/tls/5848079071.html Monarch 25 x 54 $1750
[10:25:19] <gregcnc> you'd have to look into the control if serious. at some age they were very limited
[10:25:31] <gregcnc> I can't remember the year though
[10:26:32] <MacGalempsy> it looks beefy
[10:26:50] <CaptHindsight> gregcnc: http://i.ebayimg.com/images/g/u~kAAOSwA3dYGPmL/s-l1600.jpg looks like it's been setup for horizontal :)

[10:29:09] <gregcnc> https://chicago.craigslist.org/nwc/tls/5900437479.html nobody wants this, or they are fishing
[10:30:12] <CaptHindsight> gregcnc: wasn't that up like a week ago?
[10:30:22] <gregcnc> I think a month ago
[10:31:06] <MacGalempsy> sometimes people have to get rid of it fast. time to lowball
[10:32:10] <archivist> go fetch!
[10:32:11] <MacGalempsy> http://tulsa.craigslist.org/bfs/5821505025.html
[10:32:13] <Deejay> re
[10:32:22] <MacGalempsy> too far for me!
[10:32:42] <CaptHindsight> gregcnc: called them, "he;s not in, have to call you back"
[10:32:45] <archivist> I have an adcock & shipley
[10:33:14] <gregcnc> i thought you called on that one when we fist saw it. Similar result.
[10:33:34] <CaptHindsight> gregcnc: "he will be back at 7am tomorrow"
[10:33:47] <MacGalempsy> http://tulsa.craigslist.org/tls/5827472325.html
[10:33:51] <MacGalempsy> oldest mazak
[10:34:47] <CaptHindsight> http://www.ebay.com/itm/Dunham-CNC-Lathe-Series-3000-Westinghouse-CNC-1981-/112050127716
[10:35:37] <gregcnc> I wonder if there is any life left in that one
[10:35:52] <CaptHindsight> walked into a shop the other day and they had ~40 cam operated swiss screw machines
[10:36:01] <archivist> still running parts on it
[10:36:22] <gregcnc> doesn't mean it's any good
[10:36:24] <archivist> tornos or bechler?
[10:36:28] <CaptHindsight> they said they they all hold a few 10ths
[10:36:48] <CaptHindsight> think bechler, let look at a pic
[10:37:08] <gregcnc> but linear rails are easy to replace worn iron takes more work
[10:37:31] <CaptHindsight> he's had them all for >20 years
[10:37:50] <archivist> nothing to wear almost on a swiss sliding head
[10:38:35] <CaptHindsight> his site http://www.minicprecision.com/index.html
[10:38:37] <archivist> most wear is the cams and it is simple to tweak for that last bit
[10:39:36] <CaptHindsight> Tornos, Bechler and Citizen
[10:40:00] <CaptHindsight> was 95% cam machines
[10:40:43] <archivist> cam for the production cnc for prototypes
[10:41:05] <gregcnc> if the volume is there cams still make sense
[10:41:45] <archivist> I think servos driving the cam arms should be a nice mod though
[10:42:06] <archivist> when I get funds... will play
[10:42:16] <CaptHindsight> http://www.ebay.com/itm/Bechler-AS-4-Swiss-Screw-Machine-W-3-Drill-Stations-w-5-Tool-Holders-Running-/201409458483
[10:42:19] <gregcnc> there is a shop in barrington with almost 200 cnc swiss
[10:43:02] <archivist> looks very similar to mine
[10:43:33] <CaptHindsight> lots of cnc lathes on ebay
[10:43:43] <CaptHindsight> looks like year end shop cleaning
[10:43:58] <CaptHindsight> then they will also appear late winter
[10:44:17] <archivist> spend the years spare budget on new lathes
[10:44:44] <CaptHindsight> Cincinnitti Malacron
[10:45:14] <CaptHindsight> http://www.ebay.com/itm/Cincinnitti-Malacron-210-Cnc-Lathe-/222326166234
[10:45:41] <CaptHindsight> they don't check their ads
[10:47:03] <archivist> no bids....
[10:48:19] <CaptHindsight> I need a big machine with lots of lights
[10:48:38] <CaptHindsight> impress the propeller heads when they come to visit
[10:48:50] <CaptHindsight> just needs to light up and make some noise
[10:50:40] <speedevil> shoot sparks?
[10:50:45] <CaptHindsight> looks clean http://www.ebay.com/itm/Mazak-Slant-Turn-40-Universal-1000-CNC-Lathe-4-Axis-Fanuc-6T-Controls-/291854804482
[10:51:21] <CaptHindsight> 4-axis for $3500
[10:53:04] <CaptHindsight> they have a few
[10:53:54] <CaptHindsight> http://www.ebay.com/itm/Okuma-LC30-1SC-CNC-Lathe-OSP3000-/291441819739 $1900 , 3 available
[10:55:31] <CaptHindsight> another 4-axis for $2900 http://www.ebay.com/itm/Okuma-LC40-2SC-4-Axis-Simulturn-CNC-Lathe-/111292739517
[10:57:44] <gregcnc> https://www.instagram.com/p/BNfB4U3l9QL/
[10:59:23] <_methods> hehe
[10:59:53] <_methods> sending that one to everyone in the shop
[11:03:35] <CaptHindsight> it's rare someone gets that pun
[11:03:51] <CaptHindsight> gregcnc: that cnc in rockford is still there
[11:06:19] <CaptHindsight> supposedly still works well
[11:07:55] <gregcnc> https://www.instagram.com/p/BNdPtBAhHl1/
[11:08:04] <gregcnc> put it in your shop to hold down the floor?
[11:09:26] <CaptHindsight> like the Chinaco fasteners we were talking about yesterday
[11:09:48] <CaptHindsight> threadless for easy on/off
[11:10:04] <CaptHindsight> why get dizzy spinning things around
[11:11:16] <CaptHindsight> https://www.instagram.com/p/BMr02_fh0SC/?taken-by=widgetworksmfg do they make matching nuts?
[11:15:49] <MacGalempsy> anyone watching 3% on netflix? translated from portugese
[11:20:08] <CaptHindsight> https://en.wikipedia.org/wiki/3%25
[11:21:27] <CaptHindsight> MacGalempsy: worth binge watching?
[11:22:56] <MacGalempsy> so far i am intriegued. if you like scifi its pretty good
[11:24:47] <MacGalempsy> binged the first few episodes last night
[11:24:57] <CaptHindsight> scifi Blade Runner yes, scifi Expanse, Defiance, not so much
[11:27:30] <MacGalempsy> i havent seen those last two.
[11:35:54] <CaptHindsight> 12 Monkeys and Humans started out interesting, then they must have changed writers
[11:35:58] <MacGalempsy> there is a selection process to get "offshore" and the trials are arduous and ppl cant handle getting cut, so its ruthless
[11:36:16] <MacGalempsy> never seen that either
[11:37:36] <MacGalempsy> of course everyone has their secrets
[11:59:39] <IchGucksLive> hi from a cold Germany
[12:01:31] <IchGucksLive> tomorrow cool 1k Base Caps with metall logo
[12:01:48] <IchGucksLive> 0.4mm thin
[12:02:02] <Jymmm> MacGalempsy: Like those pink pokidot lace panties you're always wearing? Seriously, you've turned them inside out way too many times, tod em in the wash already EEEEEESH
[12:02:11] <Jymmm> toss*
[12:02:54] <jdh> you kept that pic?
[12:03:21] <Jymmm> jdh: Me? Nah, it's up google forever and ever
[12:04:00] <MacGalempsy> Jymmm: when you gave those to me after a sweaty night dancing, i thought they would remain a secret
[12:04:17] <MacGalempsy> i havent washed them
[12:04:21] <Jymmm> MacGalempsy: This is the interwebz, nothing is a secret
[12:05:50] <Jymmm> MacGalempsy: But, if you want to remove all traces, you'll need to break into here and remvoe it yourself... https://en.wikipedia.org/wiki/Utah_Data_Center
[12:07:42] <CaptHindsight> Jymmm: did you come up with a heat storage device?
[12:09:20] <CaptHindsight> thermal battery
[12:10:00] <Jymmm> CaptHindsight: 2016-11-30.13:15:31 Jymmm: CaptHindsight: No TES for now.
[12:11:17] <CaptHindsight> TES = Toilet Equipped Scooter?
[12:11:31] <Jymmm> TES = Thermal Energy Storage
[12:12:13] <Jymmm> CaptHindsight: TES == https://en.wikipedia.org/wiki/Thermal_energy_storage
[12:13:05] <Jymmm> CaptHindsight: But looking more at phase change as it can store 50x more https://en.wikipedia.org/wiki/Phase-change_material
[12:13:35] <CaptHindsight> like water
[12:13:42] <Jymmm> like wax
[12:14:02] <gregcnc> what does wax cost?
[12:14:52] <CaptHindsight> candle, bees, ear ?
[12:14:53] <Jymmm> gregcnc: Fairly cheap, and I can get it in 50lb boxes
[12:15:07] <gregcnc> Oh I thought it was expensive
[12:15:10] <Jymmm> CaptHindsight: parrafin
[12:15:43] <CaptHindsight> $800/ton for paraffin
[12:16:14] <Jymmm> gregcnc: maybe $50/50lbs or so
[12:16:37] <Jymmm> gregcnc: only expensive if you go retail pricing
[12:17:45] <CaptHindsight> and you can burn it for light
[12:18:19] <Loetmichel> how about that stuff that is in those pocket warmersß
[12:18:20] <Loetmichel> ?
[12:19:27] <gregcnc> a ton would be enough
[12:19:29] <CaptHindsight> the chemical type with iron?
[12:19:48] <MacGalempsy> fill it with coal
[12:20:09] <Loetmichel> sodium acetate triphospate?
[12:20:26] <Loetmichel> s/triephosphate/trihydrate
[12:20:45] <Loetmichel> CaptHindsight: no the rechargeables
[12:21:12] <Loetmichel> those plastic sacks with a fluid in them and a metal clicker to activate them
[12:21:35] <Loetmichel> they crystalize and go ~60°C for an hour or so when activated
[12:21:36] <gregcnc> thermite
[12:21:56] <Loetmichel> and can be "remelted" at 90°C
[12:22:07] <CaptHindsight> he wants to turn wood into heat and then store the heat for later use or over a longer period of time that the burning process takes
[12:22:17] <Loetmichel> yah
[12:22:27] <MacGalempsy> di
[12:22:34] <Loetmichel> so use a water jacked in the wood stove
[12:22:55] <Jymmm> Loetmichel: No, over time, like 24-48 hours
[12:22:55] <Loetmichel> and pump the hot water thru a tank with a few 100kg of the stuff
[12:23:14] <Loetmichel> (and some radiators)
[12:24:04] <Loetmichel> works basically the same as paraffin, can just store more energy per mass AND can store it for long times
[12:24:24] <Loetmichel> because even if it completely cools down to room temp it stays liquid until activated
[12:24:34] <Jymmm> Loetmichel: Think 55gal drum of sodium acetate and a sledge hammer =)
[12:25:02] <Loetmichel> yeah, that was my thought
[12:25:12] <gregcnc> never seen these http://www.thinkgeek.com/product/9e29/
[12:25:29] <Loetmichel> these were the ones i meant
[12:26:19] <Jymmm> Loetmichel: The issue is the storage capacity, a 55gal drum of non phase change material is only around 100BTU. Where I would need around 300K BTU
[12:26:39] <Loetmichel> sodium acetate IS a phase change
[12:26:48] <CaptHindsight> are you only allowed one drum?
[12:26:48] <Jymmm> Loetmichel: Yes, I know
[12:26:57] <Jymmm> CaptHindsight: You buying?
[12:27:07] <gregcnc> interesting so it's super heated liquid, and the shock causes it to crystalize at which point it can melt to give off heat
[12:27:16] <CaptHindsight> money money money, it's always about money
[12:27:23] <Loetmichel> gregcnc: yes
[12:27:26] <Jymmm> gregcnc: Not SUPER heated, boilging water will do it
[12:28:04] <Loetmichel> Jymmm: more like "over saturated liquid"
[12:28:24] <gregcnc> super heated is not right. Super cooled
[12:28:38] <Jymmm> Loetmichel: some one came up with ping pong balls of wax too
[12:29:47] <Loetmichel> Jymmm: actually: 90°C water will do the trick
[12:30:26] <Loetmichel> its usually formulated that at 90°C all the crystals can dissolve in the water inside
[12:30:51] <gregcnc> what's happening though is it's not turning to solid as it passes solidification temp while cooling, thus supercooled
[12:31:03] <Loetmichel> and inside the bags are no "cystalisation cores" a.k.a dirt, so it doesen crystalize when cooled below that
[12:32:03] <Loetmichel> the metal "clicker" causes a supersonic shockwave and cavitation, thus providing the crystalisation cores (the micro vacuum bubbles)
[12:32:49] <malcom2073> We have a bunch of those things
[12:32:51] <malcom2073> they're pretty awesome
[12:34:09] <Loetmichel> and Jymmm is right: a (steel) drum with that stuff inside and a sledge hammer would work to start the "heater"
[12:34:32] <Loetmichel> much less hassle to heat the workshop than to try to lit a fire with ice cold fingers ;)
[12:34:56] <CaptHindsight> how much heat do termites produce eating wood?
[12:36:25] <IchGucksLive> CaptHindsight: depends on wood
[12:36:55] <CaptHindsight> Termites are considered to be a major source (11%) of atmospheric methane,
[12:38:21] <CaptHindsight> Termites rely primarily upon symbiotic protozoa (metamonads) and other microbes such as flagellate protists in their guts to digest the cellulose
[12:38:50] <CaptHindsight> so maybe just a bacteria/wood reactor
[12:41:50] <CaptHindsight> slowly digesting wood at 25C
[12:44:18] <IchGucksLive> Loetmichel: did you got router problems this week ?
[12:44:28] <Loetmichel> no
[12:44:37] <IchGucksLive> smiles
[12:44:49] <Loetmichel> i have telkom as isp... but no telekom router ;)
[12:45:03] <Loetmichel> i am not silly ;)
[12:45:19] <IchGucksLive> so fritzt the box
[12:46:03] <IchGucksLive> most speedports can be fritz
[12:47:23] <Loetmichel> the telekom hardware us usually good.
[12:47:32] <Loetmichel> the firmware however...
[12:51:39] <CaptHindsight> wood bioreactor ---> methane ----> heat
[12:52:21] <IchGucksLive> CaptHindsight: shit makes money
[12:52:33] <IchGucksLive> all over the word
[12:52:38] <IchGucksLive> l
[12:55:34] <miss0r> Finally removed from the freenode banlist. But thanks to them, I found a pretty serious security issue in my webserver. I would probally not have noticed otherwise
[12:56:32] <IchGucksLive> always good to be informed
[12:56:43] <miss0r> absolutly
[12:56:59] <IchGucksLive> you shoudt consider less X pages
[12:57:13] <IchGucksLive> consume ;
[12:58:08] <IchGucksLive> Q: will there be a RT or PAE on 16.06
[12:58:14] <IchGucksLive> 04
[12:58:28] <IchGucksLive> so ubuntu LCNc will continue
[12:58:37] <IchGucksLive> or only on Debian
[12:59:19] <roycroft> grrr
[12:59:27] <roycroft> i keep looking at the lathe i can afford right now
[12:59:47] <roycroft> and thinking "if i had this feature that would be better - maybe i can stretch a few dollars"
[12:59:56] <roycroft> and then i look at the next model up, and think the same thing
[13:00:10] <roycroft> i keep getting to the one i want but can't afford
[13:00:41] <CaptHindsight> Solar Thermal Bioreactor Heating https://www.youtube.com/watch?v=ScRfKo-3kcI
[13:04:03] <roycroft> this one looks interesting but i don't have the room for it
[13:04:04] <roycroft> http://portland.craigslist.org/mlt/tld/5849952351.html
[13:08:20] <IchGucksLive> roycroft: http://www.homedepot.com/p/JET-9-in-x-20-in-Metalworking-Bench-Lathe-321376/204357253
[13:08:58] <IchGucksLive> im off Gn8
[13:24:08] <CaptHindsight> https://www.walmart.com/ip/Jet-321130-BDB-1340A-Lathe-with-NEWALL-DP700-DRO-Installed/20977249
[13:25:44] <roycroft> i'm not sure of that little jet lathe is interesting
[13:26:00] <roycroft> a 12x36 is more what i really need
[13:26:04] <roycroft> or want, at least
[13:26:40] <roycroft> that seems to be the "entry level" size that has commonality with standard industrial engine lathes
[13:31:12] <kyle____> walmart's really branching out huh
[13:31:39] <kyle____> it's amusing to see stuff like this on walmarts website even with the knowledge that they're trying to be like amazon now
[13:37:38] <roycroft> that jet also only goes down to 130rpm
[13:37:58] <roycroft> that makes threading/knurling a bit more scary
[13:41:16] <kyle____> oh that's no big deal, just take some adderall before you start
[13:41:36] <kyle____> why pay extra to slow your machine down when you could save money and speed yourself up?
[13:48:03] <roycroft> for some strange reason i don't relish the thought of crashing the machine
[13:48:03] <roycroft> i've never crashed a lathe before (knock on cast iron)
[13:48:03] <roycroft> and i hope i never do
[13:49:21] <MacGalempsy> this damn burrito is so hot my scalp is both itching and sweating
[13:49:52] <MacGalempsy> amazingly, my mouth is not burning so much
[13:52:18] <MacGalempsy> ouch ouch burning, but soooo goood
[13:56:32] <gregcnc> salt+msg+capsaicin will make cardboard taste good
[13:57:39] <srdc> We are working on retrofitting a Mazak VMC with a 16 ATC using ClassicLadder, and were having trouble figuring out exactly how we would get the proper joint motion during the tool change sequence.
[13:58:04] <srdc> It is a stationary ATC with a rotating chain
[13:58:10] <cradek> if you need motion, probably remapping M6 is the easiest way
[13:59:04] <srdc> I was looking into that, but I wasn't sure how to pass control back and forth from CL to Gcode
[13:59:21] <srdc> because the sequence requires several different moves
[13:59:21] <cradek> might want to check out the example in sim/axis/vismach/VMC_toolchange
[13:59:59] <srdc> Ahhh...can't believe I forgot to look there. I'll go dig into that and see if it helps
[14:00:11] <srdc> Thanks for the tip.
[14:01:03] <cradek> M66 P3 L3 Q2 ; wait for tool-released = true
[14:01:17] <cradek> it uses M64/M66 for handshaking with the outside world (ladder in your case)
[14:01:22] <cradek> welcome
[14:02:42] <srdc> Perfect, this looks like what I was looking for.
[14:03:23] <srdc> Now just to finish learning how the o-word syntax works. Thanks again!
[15:05:25] <CaptHindsight> is there a pneumatic orbital sander that lasts more than a day or two?
[15:49:10] <_methods> dynabrade?
[15:49:24] <_methods> always had good luck with their pneumatic orbitals
[15:50:05] <_methods> https://www.amazon.com/Dynabrade-59020-Dynorbital-Spirit-Non-Vacuum-Orbital/dp/B00065TPK0/ref=sr_1_1?ie=UTF8&qid=1480713676&sr=8-1&keywords=dynabrade+orbital+sander
[16:00:41] <CaptHindsight> that looks like the Ingersol rand
[16:00:47] <CaptHindsight> probably same source
[16:21:53] <srdc> Don't know about the knew ones, but all the old ARO brand we get - solid aluminum housings - are rock solid.
[16:22:13] <srdc> We've picked up a few - orbital sander, etc at estate sales, auctions, etc
[16:22:28] <srdc> we haven't had to repair one yet - just plug them in and they work
[16:22:46] <srdc> i believe they are IR now though so dunno about the quality
[16:23:03] <Deejay> gn8
[16:23:29] <bpuk> I'm quite interesting in this conversation - we're currently looking at some air sanders - Chicago Pneumatic is currently looking like the most likely, but if anyone has used thier stuff...
[16:23:39] <bpuk> *interested
[16:26:16] <srdc> Have a Chicago Pneumatic solid aluminum impact wrench that is bulletproof. No experience with their air sanders
[16:26:43] <srdc> Just make sure ya don't accidentally get stuck with the other CP brand! ;-)
[16:27:10] <bpuk> theres another CP brand? (we're in the UK - so it's all listed as Chicago Pneumatic)
[16:29:10] <srdc> Sorry ... Central Pneumatic ... Harbor Freight brand ... made to look suspiciously like Chicago Pneumatic
[16:29:48] <bpuk> aaah :D yeah, I'm not likely to see those over here
[16:30:01] <Wolf_> Central (China) Pneumatic
[16:54:11] <CaptHindsight> I got a Central Pneumatic a few years ago. Returned it the same day. Not even worth trying to use them once.
[16:56:56] <CaptHindsight> https://www.menards.com/main/tools-hardware/power-tools-accessories/air-compressors-pneumatic-tools-accessories/air-tools/c-12915.htm?brandName_facet=Powermate+Vx these all look and feel like HF junk
[16:58:44] <bpuk> it's kind of annoying when the local pneumatic reps keep trying to sell you junk 'because it's cheaper, but just as good'
[16:59:00] <bpuk> Rather pay once and not have the headaches
[16:59:24] <CaptHindsight> the time alone returning it kills you
[16:59:56] <CaptHindsight> and Home Depot carries IR but at the stores they only stock Husky
[17:00:35] <bpuk> half an hour on the phone, 10 minutes dealing with the rep when he comes to collect. That's getting on 70 dollars without blinking
[17:01:56] <CaptHindsight> http://www.northerntool.com/shop/tools/category_air-tools-compressors+air-tools-accessories+air-sanders
[17:02:25] <Moronicsmurf> So this channel alive? Or just idlers. ;D
[17:02:47] <bpuk> couple of us are talking air sanders
[17:02:53] <CaptHindsight> alivedlers
[17:03:23] <Moronicsmurf> Air sanders huh.. like those you use for car paint? =)
[17:03:41] <CaptHindsight> http://www.cp.com/usen/whatwedo/powertools/sanderspolishers/
[17:03:41] <bpuk> yeah, or stripping varnish off wood in my case
[17:04:18] <Moronicsmurf> Ah right.. i prefer those long slime ones but i mostly do car stuff.
[17:04:29] <bpuk> two people at work have started getting whitefinger from electric sanders, so we've been looking for good air orbitals to try and reduce it
[17:04:57] <Moronicsmurf> well they dont really reduce white fingers.. unless you put like a absorbent material on the handles
[17:05:04] <Moronicsmurf> not in my case anyway
[17:05:07] <JT-Shop> shit something is leaking on the 300 gallon propane tank, I've lost 150 gallons
[17:05:24] <CaptHindsight> no smoking
[17:05:28] <Moronicsmurf> I imagine if you get a lighter you could find it. ;D
[17:05:41] <bpuk> err - I hope the tank is outside?
[17:05:49] <JT-Shop> aye
[17:06:18] <Moronicsmurf> wouldnt that smell?
[17:06:22] <Moronicsmurf> at least a bit
[17:06:25] <JT-Shop> been so windy I didn't smell it till today
[17:06:29] <bpuk> well, that's most of the terror out of the way - start huntin?
[17:06:40] <CaptHindsight> depends on if it took 15 minutes or 15 days to leak
[17:06:50] <JT-Shop> 2 weeks
[17:07:04] <Moronicsmurf> i once forgot an acetylen bottle open in the outhouse of my workshop
[17:07:11] <Moronicsmurf> one day there was no outhouse there anymore
[17:07:43] <JT-Shop> lit your fart?
[17:08:22] <Moronicsmurf> i was inside and just heard a low rumble
[17:08:31] <Moronicsmurf> came out and no more building
[17:09:01] <Moronicsmurf> i went and bought a plasma cutter after that.. felt safer
[17:15:03] <jdh> you need a few hundred watt laser cutter
[17:15:39] <bpuk> I've never found a good comparison for watts to thickness for various materials on a laser
[17:15:57] <jdh> depends on teh laser
[17:16:06] <bpuk> assume CO2
[17:16:30] <bpuk> target thickness, 3mm 316 stainless
[17:18:14] <Moronicsmurf> 150W would do about 2mm of that
[17:18:22] <Moronicsmurf> if you used a oxygen assist you could do 6mm
[17:18:31] <bpuk> really? 150W is enough for 2mm?
[17:18:35] <Moronicsmurf> depends on if you are in a hurry or not
[17:18:50] <bpuk> wow. I'd been estimating 2kW for 2mm
[17:19:03] <Moronicsmurf> there is a commercial machine even that runs that.
[17:19:12] <Moronicsmurf> 2kW would punch 20mm with ease :D
[17:19:29] <Moronicsmurf> the machine i ran at a former job was a 3kW machine we did up to 34mm in steel
[17:19:29] <bpuk> smallest commercial machines I've seen have been 4kW upwards
[17:19:44] <bpuk> ok - that gives me some nice perspective :)
[17:19:54] <Moronicsmurf> lemme look for that company
[17:20:00] <Moronicsmurf> i prob. have it in a folder here somewhere
[17:20:42] <Moronicsmurf> 400W is quite obtainable and if you use a gas assist of some sort its not the laser cutting then is it. =)
[17:21:00] <Moronicsmurf> but cutting with oxygen is expensive without a generator for it
[17:21:08] <Moronicsmurf> kern laser systems were they called.
[17:21:25] <bpuk> for CO2 I can probably manage 500W with a bit of effort
[17:21:42] <bpuk> if I can cut the thickness I'm interested in, I'll skip the plasma
[17:22:12] <Moronicsmurf> i just run a plasma its affordable
[17:22:24] <Moronicsmurf> and with a fine nozzle you get a bit wider kerf but the same quality on thinner stuff
[17:22:35] <Moronicsmurf> and you can run it at a higher cutting speed
[17:22:52] <Moronicsmurf> but when tuned properly you dont need to handle slag on that either
[17:23:13] <bpuk> mostly stainless, 2-3mm. Pretty much all of it needs to be welded, and is decorative as well as functional
[17:23:35] <Moronicsmurf> yeah i make race car parts mainly
[17:23:44] <Moronicsmurf> so alot of aluminium and stainless
[17:23:55] <bpuk> we spent approx 40k on laser cutting last year
[17:24:08] <Moronicsmurf> gbp i guess
[17:24:17] <bpuk> yeah
[17:24:18] <Moronicsmurf> thats a half million in my currency. ;D
[17:24:46] <Moronicsmurf> think my hypertherm pmx85 paid for itself by the 6th job i used it for
[17:25:25] <bpuk> to be honest, I'm pretty sure a commercial plasma would pay for itself quickly, but I can't convice the boss
[17:27:00] <Moronicsmurf> so he rather pay 40k on outjobs, then paying what 4.5k on plasma and about 2k more for a proper plasma table
[17:27:11] <Moronicsmurf> and just never pay for outjobs again.
[17:27:25] <Moronicsmurf> that guy needs to learn math
[17:27:58] <bpuk> about 20k typical for the range we're looking at
[17:28:10] <bpuk> haven't looked into the cost of a laser (which would be the preference)
[17:28:43] <Moronicsmurf> 20k plasma table / machine combo im guessing then.
[17:28:48] <jdh> more maint on big lasers
[17:28:57] <Moronicsmurf> shitload of more maintenance on lasers
[17:29:09] <Moronicsmurf> daily lens cleaning and aligning
[17:29:12] <Moronicsmurf> drove me mad
[17:30:56] <bpuk> Moronicsmurf: Yeah, hypertherm machine plasma, not hi-def. table by who knows
[17:31:17] <bpuk> you can get stuff around the 10k range, but the plasma is underpowered
[17:31:32] <Moronicsmurf> my pmx85 is definitely not underpowered tho
[17:31:42] <Moronicsmurf> cuts 38mm steel plate with no effort
[17:31:57] <Moronicsmurf> punches straight holes even
[17:32:15] <bpuk> 10k with table will get a pmax 30 or 45
[17:33:18] <Moronicsmurf> yeah sure but would be cheaper to just buy the plasma seperate and make the table, the time it took goes away fast
[17:33:24] <Moronicsmurf> you dont need fancy thc stuff in the beginning
[17:33:33] <Moronicsmurf> just X/Y and a manual set height
[17:33:45] <bpuk> cost isn't the problem
[17:33:49] <bpuk> philosophy is
[17:34:02] <Moronicsmurf> i see
[17:34:04] <bpuk> if I can find stuff cheap enough, I can buy it without him noticing
[17:35:08] <Moronicsmurf> hehe thats one way
[17:35:27] <Moronicsmurf> anyone here have got a RTAI/Preempt kernel working in Linuxmint 18?? *fiddling and swearing*
[17:42:11] <Moronicsmurf> guessing no then. =) *keeps fiddling with this then*
[17:44:31] <bpuk> Sorry, I rarely do anything but a stock install for the machines, and a RIP dev environment for dev
[17:45:10] <Moronicsmurf> yeah i just trying to figure out how this stuff work at all.. runs dynamicmotion kstep otherwise
[17:45:13] <Moronicsmurf> its plug n play
[17:45:22] <Moronicsmurf> but this has options top customize so much
[17:45:28] <Moronicsmurf> to*
[17:45:56] <pcw_mesa> I dont think there's anything too difficult with Mint18 at least after the LinuxCNC gurus fixed the main issues (have it running on 3 machines here)
[17:52:22] <Moronicsmurf> pcw_mesa; well you are the maker of the hardware and much of the drives.. i imagine you dont think much is especially difficult. =)
[17:52:43] <Moronicsmurf> i cant even find a preempt kernel for linuxmint
[17:52:51] <pcw_mesa> Yeah but i am not a software guy at all
[17:52:52] <Moronicsmurf> seems it needs to be compiled
[17:53:03] <Moronicsmurf> hardware is harder than software.. alot harder..
[17:53:47] <Moronicsmurf> have you seen downplay the difficulty level of this before - this is damn rocket science for me :D
[17:57:23] <pcw_mesa> Making Preepmt-RT kernels is not that hard, here's a script for 4.6.7
[17:57:24] <pcw_mesa> http://pastecode.org/index.php/view/634244
[17:57:26] <pcw_mesa> (you need to at the minimum choose the 32/64 bit mode and enable a fully preemptable kernel in xconfig)
[17:57:28] <pcw_mesa> you could also have this make debs for easier cleanup/distribution
[17:58:14] <Moronicsmurf> thx. =)
[17:58:20] <Moronicsmurf> i havent compiled a kernel since -93
[17:58:27] <Moronicsmurf> so this is a relearning curve =)
[17:59:13] <pcw_mesa> jepler has some prebuilt Preempt-RT kernels for Jessie also
[18:00:27] <JT-Shop> pcw_mesa: that script is for Mint18?
[18:00:45] <Moronicsmurf> it looks a general make a kernel script
[18:01:19] <pcw_mesa> its os agnostic (well probably debian only)
[18:01:19] <Moronicsmurf> after patching with the rt stuff you dont really need to select anything in the kernel menus these days?!
[18:01:36] <Moronicsmurf> just click the 64bit and hope for the best?
[18:02:23] <pcw_mesa> you need to select "Fully Preemptable Kernel" or you wont get a RT kernel
[18:02:54] <JT-Shop> ok
[18:02:59] <Moronicsmurf> hmm didnt find that option.. *keeps looking*
[18:03:27] <pcw_mesa> its in "processor types and features"
[18:05:25] <Moronicsmurf> and there i effed something.. *luls* start over. =)
[18:05:49] <Moronicsmurf> ah nice you can get Atom support as well. =)
[18:06:23] <Moronicsmurf> always wanna try to get this to run on a Lattepanda
[18:06:23] <pcw_mesa> ahh the jessie kernels are in backports
[18:06:24] <pcw_mesa> "jepler for debian jessie you can install 4.1, 4.4, or 4.6 realtime kernels from snapshot.debian.org -- https://emergent.unpythonic.net/01466682649"
[18:07:33] <Moronicsmurf> damn i have googled for something like that all day. =)
[18:07:38] <Moronicsmurf> or since noon at least
[18:09:38] <Moronicsmurf> pcw; do i figure this correctly that these cards of yours will remove much of the latency issues associated with software stepper generation. And by doing that a lesser hardware platform could be used successfully?
[18:09:48] <pcw_mesa> If you have older hardware, I reccomend the 4.1 kernels
[18:09:52] <Moronicsmurf> thinking of trying to get this 1.8ghz, 4gb ram lattepanda working.
[18:10:05] <Moronicsmurf> and using this 7i76E card i got today
[18:10:31] <Moronicsmurf> have a small stockpile of mesa cards but not used any of them in anything yet ;)
[18:10:45] <pcw_mesa> yes, the steprate is not affected by latency anymore (though stuff as slow as Atoms is pretty painful)
[18:11:24] <Moronicsmurf> im thinking of stripping out UI completely. A friend of mine is fiddling with making a web interface instead binding it through a ehm.. rest service?
[18:11:47] <Moronicsmurf> hes nifty at making realtime webstuff
[18:12:43] <Moronicsmurf> http://www.lattepanda.com/product-detail/?pid=3
[18:12:50] <Moronicsmurf> Quad core 1.8ghz, 4Gb ram
[18:12:54] <Moronicsmurf> not thaaat slow
[18:13:08] <Moronicsmurf> at least if you kill off all the other crap you wont need..
[18:13:11] <Moronicsmurf> bluetooth and such
[18:24:20] <Moronicsmurf> Gotta say i enjoy using IRC again.. takes a bit of time getting used to irrsi again tho. =)
[19:10:44] <Tom_L> CaptHindsight, little late to the party but i'll second _methods on dynabrade sanders
[19:11:14] <Tom_L> i've got a 6 & 8" that have lasted for years
[19:32:51] <BeachBumPete> Evening linuxCNC :)
[19:33:02] <bpuk> ey-up pete
[19:33:19] <BeachBumPete> hello puk
[19:34:07] <BeachBumPete> anyone got any cool CNC plans for the weekend?
[19:34:19] <bpuk> Got some 4 axis engraving to do
[19:34:38] <bpuk> would be better as 5 axis, but don't have time to rig up a 5th :(
[19:34:47] <BeachBumPete> wow sweet... just wrapping or actual fourth
[19:35:17] <bpuk> mostly hand coded, it's sorta wrapping, but it's at an angle
[19:35:31] <bpuk> so I'll tilt the table and tweak by hand
[19:35:42] <BeachBumPete> what machine?
[19:35:51] <bpuk> bridgeport interact Mk2
[19:36:03] <BeachBumPete> ah ok
[19:36:57] <bpuk> running on original drives, with a mesa interface (and heidenhain voltage->current converters)
[19:37:07] <zeeshan> hi
[19:37:09] <BeachBumPete> can't go wrond with mesa
[19:37:18] <BeachBumPete> hello zeeshan
[19:37:28] <zeeshan> machine some parts?!?
[19:37:47] <BeachBumPete> what are you machining?
[19:37:57] <zeeshan> no im asking you
[19:37:58] <zeeshan> :)
[19:38:12] <BeachBumPete> oh no not yet I ordered some material tho
[19:38:13] <bpuk> I've been tempted by pico systems a couple of times on the resolver based boards - but haven't done so yet
[19:38:29] <zeeshan> nice
[19:38:42] <bpuk> if I get the models done, I might make some jewelery moulds on the router
[19:38:53] <BeachBumPete> I am planning to try to machine a custom rail that is a new design this weekend hopefully
[19:39:19] <bpuk> nice :)
[19:39:39] <bpuk> after that, I'm ordering bearings and raw material for the mini-mill
[19:40:11] <bpuk> but that's going to be a fiddly build - so will probably take me a year or so ;)
[19:40:12] <BeachBumPete> I have been wanting to get some work done on the CNC lathe for awhile and I am thinking I might pull it out of the corner and start installing the components I have for it inside the electronics enclosure
[19:40:52] <bpuk> do it :)
[19:41:05] <bpuk> lathes are comparatively simple
[19:41:16] <BeachBumPete> I am probably going to tomorrow..
[19:41:36] <bpuk> bpuk waves a carrot and a stick at pete
[19:41:38] <BeachBumPete> well this one will be slightly different than my Cincinatti but with the same basic setup
[19:41:51] <BeachBumPete> where are you located bpuk?
[19:41:56] <bpuk> northern UK
[19:42:00] <zeeshan> lol @ lathes are simpler
[19:42:00] <zeeshan> hahaha
[19:42:01] <BeachBumPete> ah OK
[19:42:15] <bpuk> zeeshan: I'm glad you got the joke ;)
[19:42:51] <BeachBumPete> I guess I missed the joke...
[19:43:13] <bpuk> I put about 10 hours into converting the mill, I hold a tenth pretty easily
[19:43:24] <bpuk> I've got about 200 hours into the lathe, and it's still in bits
[19:43:33] <BeachBumPete> ah ok
[19:43:39] <bpuk> it _should_ be simpler
[19:43:55] <bpuk> but I've hit pretty much every problem doing it
[19:44:14] <BeachBumPete> honestly it IS simple considering I am going to use much the same basic layout that I used on my Cincinatti Arrow 500 VMC
[19:44:22] <zeeshan> you hold tenths on a mini mill?
[19:44:52] <bpuk> on the BP interact (as long as I avoid the bad part of the dovetails)
[19:45:07] <bpuk> the mini-mill I'm building, tenths will be no problem
[19:45:12] <Wolf_> my mini mill will hold tenths… long as you don’t turn it on
[19:45:45] <BeachBumPete> my machine makes pretty parts ;)
[19:46:12] <zeeshan> deflection is a simple concept ya know
[19:46:48] <bpuk> yup, and for most materials, it isn't a significant problem
[19:47:35] <bpuk> (I'm aiming for 218x246 on the mini mill. ISO30 spindle (which is the hard part)
[19:48:08] <bpuk> since that's the largest mould base I need to do detail work on
[19:52:42] <bpuk> my internal argument at the minute is oil-mist or pre-grease - is the extra speed worth the annoyance of oil-mist
[19:53:19] <zeeshan> you just made it external
[19:53:21] <zeeshan> :[
[19:54:03] <bpuk> yup - I figure I'll get good input here
[19:55:08] <bpuk> I can't grind accurately enough on rotary parts for hydrostatic spindle bearings - so I'm stuck with ball bearings. I figure 15k max speed on grease, 20-22k on oil-mist
[20:06:54] <Frank_10> hi
[20:25:06] <andypugh> I can hold tenths with a wood chisel. Tenths of mm that is.
[20:27:57] <zeeshan> :)
[20:28:09] <zeeshan> andypugh: what do you brits call shafting "bright bar"
[20:28:19] <BeachBumPete> I need to figure out how I can add some castors to the CNC lathe base so I can move it around without too much drama
[20:28:29] <Tom_L> zeeshan i can beat it into tolerance
[20:28:41] <andypugh> zeeshan: Bright Bar works as a phrase
[20:29:00] <zeeshan> whatcha mean
[20:29:33] <bpuk> I'd order 60mm bright bar if I needed a cold-drawn bar
[20:31:39] <andypugh> BeachBumPete: I made a frame and jack-down casters for my lathe. Ir hooks into the hold-down bolt holes. Though in this picture it is using cargo straps as a test. http://2.bp.blogspot.com/-iR_qAXhV6Ng/Vc5mZ2Yu4fI/AAAAAAAAFbA/HyZ3fTLj9ZY/s1600/IMG_2063.jpg
[20:32:10] <zeeshan> having a light lathe must be nice
[20:32:11] * zeeshan hides
[20:32:11] * zeeshan hides
[20:32:14] <BeachBumPete> andypugh that is sort of an idea I have seen before
[20:32:33] <andypugh> BeachBumPete: If it looks a bit funny, it’s part of a modular system that also assembles with shorter bars to move the mill.
[20:32:34] <BeachBumPete> my CNC lathe has a base that has two seperate feet as it were
[20:32:47] <BeachBumPete> Oh I did not mean it looked funny
[20:33:00] <BeachBumPete> just that it is a bit different from mine
[20:33:13] <zeeshan> i need to build better skates
[20:33:13] <BeachBumPete> the headstock FOOT is quite wide and long
[20:33:22] <andypugh> zeeshan: It’s possibly the heaviest 10x20 lathe ever made :-)
[20:33:24] <BeachBumPete> and the tailstock foot is about half its size
[20:33:30] <zeeshan> andypugh: i kid
[20:33:43] <BeachBumPete> mine is like 3k or so
[20:33:56] <zeeshan> its gotta be more!
[20:34:02] <BeachBumPete> the two FEET have a thick base plate
[20:34:22] <BeachBumPete> each base plate has two leveling bolts
[20:34:45] <BeachBumPete> I was considering making a bar tig welded to top of that plate at both ends
[20:35:17] <bpuk> andypugh: hows the lathe running since the rebuild?
[20:35:17] <BeachBumPete> and adding a castor setup to each end of them both
[20:35:19] <andypugh> The Holbrook is meant to be 750 kg. Though it did bend an engine hoist in the 1.5 ton position.
[20:35:46] <zeeshan> damn you guys
[20:36:07] <Tom_L> zeeshan put yours on wheels
[20:36:08] <andypugh> bpuk: To be honest, once it was done I moved on to the backlog other things. I haven’t actually really used it in anger yet.
[20:36:14] <zeeshan> youre making it sound so complicated to move these machines
[20:36:17] <zeeshan> try moving 12000lb!!!!!!!
[20:36:21] <zeeshan> you'll blow up your skates
[20:36:25] <zeeshan> (i did)
[20:36:33] <BeachBumPete> its not complicated really
[20:36:42] <zeeshan> put it on some damn pipes!!
[20:36:45] <andypugh> zeeshan: Using flat-fish was probably an error.
[20:36:48] <bpuk> zeeshan: the home lathe is a denford! I move it with a crowbar and 1" pipe
[20:36:49] <BeachBumPete> I actually moved it with two large garage jacks
[20:36:58] <zeeshan> hah
[20:37:03] <zeeshan> i tried lifting mine with the garage jack
[20:37:07] <BeachBumPete> but I want to be able to EASILY move it
[20:37:16] <zeeshan> i had to warranty it :D
[20:37:31] <bpuk> if you can easily move it - the machine can easily move ;)
[20:37:37] <zeeshan> hes workin on it
[20:37:41] <zeeshan> not perm solution i hope!
[20:37:41] <BeachBumPete> OK zeeshan you win....you have the heaviest lathe here
[20:37:55] <zeeshan> i also have something else that is heavy
[20:37:59] <bpuk> zeeshan: do you sit on the saddle to oil it? :P
[20:38:02] <Tom_L> it's not a lathe until it cuts something besides his hand
[20:38:23] <zeeshan> BeachBumPete: i'm just trolling
[20:38:33] <zeeshan> i used to think all these weights were heavy
[20:38:37] <BeachBumPete> you are not bothering me man
[20:38:44] <zeeshan> now at work we have machines that are 100 tons
[20:38:51] <zeeshan> and they're moving them like cake
[20:38:52] <andypugh> I made the frame for the Holbrook to be able to have it clse to the wall bit be able to get it away from the wall to do routine servicing inside the base (where the gearbox and notor are)
[20:39:10] <BeachBumPete> well that is kind of the same reason I want the wheels
[20:39:18] <zeeshan> bpuk: unfortunately i dont know where all the oil holes are
[20:39:18] <BeachBumPete> the electronics cabinet has a HUGE door on it
[20:39:18] <zeeshan> ;[
[20:39:29] <bpuk> if you're moving machines often - you need a bigger shop
[20:39:36] <BeachBumPete> and I also intend to eventually run a bar feeder of some sore
[20:39:51] <BeachBumPete> sort
[20:40:04] <bpuk> zeeshan: first year of my dad's apprenticeship was spent oiling a gun lathe - by sitting on the saddle with a (large) oilcan
[20:40:08] <zeeshan> do you have a tool setter?
[20:40:29] <bpuk> sure, it's called the machine ;)
[20:40:37] <zeeshan> nahh im thinking with bar feeding
[20:40:41] <zeeshan> if youre doing anything of decent tolerance
[20:40:48] <zeeshan> it's nice to be able to command a tool probe cycle
[20:40:54] <zeeshan> so it can truly run automatic
[20:41:03] <BeachBumPete> the ability to move the machine out for working on the electronics and being able to position for optimal use of the shops length would be nice
[20:41:51] <BeachBumPete> but tomorrow I intend to use the two jacks to move it out from the wall so I can get to the big cabinet
[20:44:18] <yasnak> The collet closers on the mills make amazing use of all our swiss barends
[20:44:30] <yasnak> I feel so good using ALL the bar, not just 11 of the 12 ft :P
[20:44:48] <BeachBumPete> nice
[20:45:07] <BeachBumPete> I've got a ways to go before I can do that but I hope to be able to soon ;)
[20:54:50] <andypugh> Roger the f1-2000 man just sent me an interesting video. He needed to make some tiny hex-socket screws
[20:56:21] <andypugh> You have probably seen wobble-broaches? Well, he improvised by puttin a home-made broack on a flexible coupling in the mill spindle and orbiting the work round that. Very cunning. And cheap.
[20:57:07] <zeeshan> haha nice
[21:05:39] <zeeshan> https://youtu.be/LN-wa3HyY4w?t=129
[21:05:48] <zeeshan> https://youtu.be/LN-wa3HyY4w?t=127
[21:05:52] <zeeshan> i saw a demonstration of this in real life
[21:05:53] <zeeshan> lol
[21:05:57] <zeeshan> its kind of nuts.
[21:06:07] <zeeshan> in cast iron it's even crazier
[21:06:13] <zeeshan> https://www.youtube.com/watch?v=r_3kwBoHh50
[21:09:00] <Tom_L> heck my sherline'll do that !
[21:09:27] <andypugh> Once
[21:09:43] <zeeshan> i puckered up
[21:09:51] <zeeshan> cause it really seems abnormal
[21:09:55] <Tom_L> i've often wondered how they get the holes in bits that have thru tool coolant
[21:09:58] <zeeshan> goes against all your machinist gut feelings
[21:10:09] <zeeshan> Tom_L: its carbide drill
[21:10:12] <zeeshan> sintered carbide
[21:10:30] <Tom_L> any thru tool coolant....
[21:10:30] <andypugh> Yes, that makes the question even harder to answer
[21:10:40] <zeeshan> huh
[21:11:41] <Tom_L> what spindle rpm are they running?
[21:11:55] <zeeshan> the one i saw was 10000 rpm
[21:12:02] <zeeshan> i think 400 ipm
[21:12:32] <Tom_L> i suppose as long as you're ipm is right no reason it won't work
[21:12:55] <Tom_L> if the machine can take it..
[21:13:33] <Tom_L> ha, that linked me to a bunch of 'how it's made' videos
[21:13:39] <Tom_L> haven't watched that in a while..
[21:14:55] <zeeshan> :D
[21:15:00] <t12> evening
[21:30:12] <CaptHindsight> Tom_L: thanks
[22:15:19] <yasnak> they sometimes put the holes in during extrusion of the carbide, then before hardening they twist it
[22:15:33] <yasnak> then the machine picks up the holes and already knows the helix...the drill is ground
[22:15:43] <yasnak> but again, thats on small small drills that I've done :P
[22:58:04] <XXCoder> bo
[22:58:24] <tiwake> eek
[22:59:32] <evilroot> Sup?
[22:59:50] <tiwake> ponies
[23:00:11] <evilroot> Anybody have experience converting old school CNC machines to modern controls?
[23:01:05] <evilroot> I have 12 X/Y/Z systems from 1991 that need to be brought up to par so they can do useful work again!
[23:04:25] <XXCoder> can be done by computer change I guess
[23:04:44] <XXCoder> besides that dunno as never upgraded a old cnc gheh
[23:06:18] <tiwake> evilroot: depending on how its set up, you might need to get new servo/stepper drivers
[23:06:48] <tiwake> and that would be the most expensive thing, if its a full size mill/lathe/whatever
[23:09:41] <evilroot> The onboard control electronics are entirely proprietary
[23:10:05] <evilroot> You need a Windows XP comp with a special USB dongle to run the special software to talk to the bot
[23:10:23] <evilroot> I intend to replace that with LinuxCNC
[23:10:35] <evilroot> Or perhaps something else
[23:11:10] <Wolf_> thats the controller. real question is how the controller talks to the motor control (servo amps/stepper driver)
[23:12:00] <evilroot> Motor drivers are no problem, I'm an Electronics Engineering Technician with a speciliazation in surface mount soldering
[23:12:17] <evilroot> Coding and controller, that's my weak spot
[23:12:20] <tiwake> evilroot: no... it depends on how its set up
[23:12:29] <Wolf_> well, what protocols do the drivers take?
[23:12:37] <evilroot> Gcode
[23:12:40] <Wolf_> ...
[23:12:40] <tiwake> but it does take at least a little bit of reverse engineering of the electronics
[23:12:42] <Wolf_> no
[23:12:54] <Wolf_> the servo amp/stepper drivers on the cnc machine
[23:13:14] <evilroot> On the big one, just how many steps
[23:13:40] <evilroot> One the smaller ones native gcode telling the servo what position to move to
[23:13:42] <Wolf_> eh, step/dir input?
[23:13:46] <tiwake> evilroot: is your machine steppers? DC servos or AC servos?
[23:13:49] <evilroot> Yes, step/dir
[23:13:59] <Wolf_> well thats easy…
[23:14:29] <evilroot> I have several machines. The big guy is 20ft x 15ft x 1ft X/Y/Z
[23:14:58] <Wolf_> gcode direct to servo?
[23:15:22] <evilroot> No, I have a servo drive board that translates
[23:15:35] <evilroot> Geckodrive
[23:15:48] <evilroot> (Or that's the plan at least)
[23:16:28] <Wolf_> depending on what drivers are on the machine to convert you may just need a mesa board to talk to the servo amps
[23:17:05] <evilroot> The biggest thing is my customer need to final result to be easy to use
[23:17:37] <evilroot> They want to just send it a file from their fancy iMacs and have the machine do the rest
[23:17:58] <Wolf_> lmao, thats really easy
[23:18:08] <Wolf_> outsource the machine work...
[23:18:36] <evilroot> Excpet they paid $30k for the machine!
[23:18:38] <tiwake> email the drawing to a company that does the work
[23:18:40] <evilroot> haha
[23:19:02] <evilroot> They want to pay ME to do the work, or modify the machine so IT will
[23:19:22] <tiwake> machines are dumb though
[23:20:10] <Wolf_> not many cnc that you can just toss a cad file at and go
[23:20:46] <tiwake> rapid prototyping maybe, on some
[23:22:21] <XXCoder> cnc mill that can just get cad file and make it? jeez
[23:22:38] <Wolf_> would be nice, right...
[23:23:03] <XXCoder> indeed
[23:23:05] <evilroot> Well they want it to work like their 3d printer
[23:23:16] <evilroot> I figure it ought to be possible
[23:23:35] <Wolf_> what material is the cnc machine working in?
[23:23:41] <evilroot> Just code a first, second, and finial finishing pass
[23:23:50] <evilroot> Wolf_: Pine
[23:24:00] <Wolf_> wood, so router machine
[23:24:04] <evilroot> Yes
[23:24:25] <evilroot> They do fancy custom furniture
[23:24:32] <Wolf_> 2d or 3d cut profiles?
[23:25:48] <XXCoder> its not possible with 3d printer in most cases
[23:25:49] <XXCoder> unless its SLA
[23:26:58] <Wolf_> they might not really understand the slicing process is really cam
[23:29:53] <XXCoder> dunno if they do yeah
[23:30:14] <XXCoder> printing should be re-done from bottom up to be more proper cnc engineered stuff
[23:30:24] <evilroot> 2d, we're talking removal no additive
[23:30:39] <Wolf_> …
[23:30:43] <XXCoder> reprap has some very strange stuff
[23:31:01] <Wolf_> so no overhangs or top features? on furniture?
[23:31:03] <evilroot> Don't even get me started on my additive printers, haha
[23:31:23] <evilroot> No, they do table tops and seats
[23:31:37] <evilroot> The bases are welded steel
[23:31:40] <Wolf_> ahh ok, yeah might be simple then
[23:31:55] <evilroot> Now we're on the same page, heh
[23:32:16] <evilroot> The smaller machines . . . honestly I don't know how I'm going to use them yet
[23:32:40] <evilroot> I have two arms and 10 X/Y/Z
[23:32:44] <tiwake> if the offset never changes, and the tool never changes, and the location of the material never changes, then it might be alright
[23:33:05] <evilroot> Offset and location no, tool should
[23:33:17] <Wolf_> http://i.imgur.com/IKemF8k.png?1 milling isn’t always simple :D
[23:33:29] <XXCoder> yeah with proper loader and unloader it can even run forever (on stock limit anyway)
[23:33:39] <evilroot> That's the idea
[23:34:23] <XXCoder> wolf yeah can be nightmare too. like one part that have to hollow out "arm" on part. that area is concave very concave, hole area is smaller than volume
[23:34:29] <XXCoder> tool paths is insane
[23:34:37] <evilroot> The Cartesian bots are Sieko XM-5000's
[23:35:15] <XXCoder> imange trapezoid but with hole as smaller end
[23:35:19] <Wolf_> yeah, that pic is one of my milled parts off my x2 conversion, 3 separate ops to make it… damn pain in the ass
[23:35:21] <XXCoder> thats volume it has to cut out
[23:35:28] <XXCoder> just 3? lol
[23:35:44] <evilroot> 1M x .8M x .4M
[23:35:45] <Wolf_> well, 3 times in the vice
[23:35:53] <Wolf_> like 5 tools lol
[23:36:08] <evilroot> With 1M/sec move speed and .04mm resolution
[23:36:46] <evilroot> Achieved by massive Japanese made servomotors and agressive leadscrews
[23:37:00] <Wolf_> http://i.imgur.com/cbTjU5A.jpg :D
[23:37:01] <evilroot> Terrifying machines
[23:37:20] <Wolf_> sounds fun
[23:37:31] <XXCoder> fancy
[23:37:42] <evilroot> I have a few of the original controllers and a teaching pendant
[23:38:06] <evilroot> They work, though the optical endstops are shot
[23:38:24] <evilroot> (Pretty easy fix, that)
[23:38:58] <evilroot> http://www.cnczone.com/forums/diy-cnc-router-table-machines/267388-cnc-software.html
[23:39:10] <evilroot> This guy has one of the same machines, just smaller
[23:39:35] <Wolf_> endstops don’t sound like much of a problem imo
[23:41:13] <Wolf_> and servo motors are fun http://i.imgur.com/EOp8e4l.jpg
[23:42:10] <evilroot> We're talking 1200W servos
[23:42:27] <Wolf_> I don’t keep those on my desk :P
[23:42:53] <evilroot> Me neither, but I have them on a pallet!
[23:43:09] <Wolf_> are they brushed or BLDC
[23:43:51] <evilroot> BLDC
[23:45:14] <Wolf_> best bet is to start figuring out what the BLDC amps use for inputs…
[23:46:57] <Wolf_> 1200w amp isn’t going to be cheap I would think
[23:49:53] * Wolf_ has 1410w servo… after you add them together…
