00:38 DagoRed yay
22:30 rue_shop2 armyofevilrobots, you using a cartridge heater?
22:41 armyofevilrobots rue_shop2: Yes. Found a little 12V one from Tinkerine.
22:41 armyofevilrobots http://www.tinkerines.com/store/heating-elements/cartridge-heater/
22:42 armyofevilrobots I am actually running his whole j-head assembly. Works good.
22:52 rue_shop2 20w, hmm
22:52 rue_shop2 http://www.ebay.com/itm/321233947908
22:52 rue_shop2 thoughts?
22:53 rue_shop2 6mmx20mm
22:53 armyofevilrobots awesome. Looks like a pretty standard one. Actually, the one I have looks more like that than the picture on Tinkerine now.
22:53 armyofevilrobots and it works great.
22:54 rue_shop2 hmm my head is almost dead on 20mm wide
22:54 rue_shop2 ok
22:54 rue_shop2 30w vs 50w, I wonder if 50 will heat up too fast
22:54 armyofevilrobots get some of that glass fabric silicone insulation to wrap the whole thing.
22:54 armyofevilrobots and 50W is fine as long as you have PID I think.
22:54 rue_shop2 the control loop on marlin seems pretty good
22:54 armyofevilrobots Yeah. I am stable +- a degree.
22:55 rue_shop2 wow
22:55 rue_shop2 glass fabric silicone...
22:55 rue_shop2 I'm failing to come up with a mental image...
22:55 armyofevilrobots Looking for link, one sec.
22:56 rue_shop2 I have some uber-high-temp stuff I used on the boiler firebox, its a tube..
22:56 armyofevilrobots yeah, mine is a tube too, and it's cross-hatch wound, so it works like the sleeves on your air muscles.
22:58 armyofevilrobots It's like this stuff.
22:59 e_shop2 falls off the edge of his
23:00 armyofevilrobots http://www.firesleeveandtape.com/high-temperature-heat-flame-fire-resistant-saturated-braided-fiberglass-sleeve-firesleeve-wire-cable-hose-protection.html
23:00 armyofevilrobots damn paste. Sorry.
23:00 rue_shop2 iiinteresting
23:00 rue_shop2 trying to think where I have seen that before
23:01 rue_shop2 I think that stuff is better than what I'v seen....
23:02 armyofevilrobots http://www.aliexpress.com/item/ID1-0-66-Insulation-Fire-Sleeve/1531484446.html
23:02 armyofevilrobots Probably don't need 66 feet ;)
23:02 rue_shop2 is that in part to soften the transfer rate of the heat?
23:02 armyofevilrobots yeah, and to protect against sudden temp drops when the fan kicks in for bridging or surfacing.
23:03 rue_shop2 ok...
23:03 armyofevilrobots There we go. It's called "fire sleeve'
23:03 rue_shop2 should I send you a dxf from my drafting program to see if it'll open on what you have for the router?
23:04 armyofevilrobots Sure, but it'll almost certainly work.
23:04 rue_shop2 I find that scaling can sometimes be odd with it
23:04 armyofevilrobots http://www.aliexpress.com/wholesale?SearchText=fire+sleeve+insulation&catId=&initiative_id=SB_20140130204656
23:05 myofevilrobots resists urge to pull out vis
23:06 rue_shop2 haha
23:09 rue_shop2 that work for file transfer?
23:18 Curious looks ar
23:20 zze looks
23:20 MrCurious any robotic develpments while i have been hybernating learning openstack?
23:26 myofevilrobots glad he's not the only
23:28 armyofevilrobots Sorry rue, was on another page. Looks like it's waiting for you to send, or crashed or something.
23:33 rue_house heh, it does that, I'll go try the send again, the transfers are easily blocked by firewalls
23:34 rue_shop2 if it wont go, I'll use next option
23:36 rue_shop2 ok, next option
23:36 rue_shop2 http://eds.dyndns.org/~ircjunk/not_public_dont_open/test.dxf
23:37 armyofevilrobots That works :)
23:38 rue_shop2 it should be 1cm square
23:38 rue_shop2 centered at 0,0
23:38 Jak_o_Shadows Bunnings is near useless
23:38 rue_shop2 Jak_o_Shadows, what you trying to get?
23:39 rue_shop2 a parting tool?
23:39 Jak_o_Shadows M5 bolts...
23:39 rue_shop2 what pitch?
23:39 Jak_o_Shadows That's a good question.
23:40 rue_shop2 my chart only shows M5 in 0.8
23:41 rue_shop2 where did Triffid_Hunter go?
23:42 armyofevilrobots rue_shop2: It loaded as 1x1 mm centered at 0,0.
23:42 armyofevilrobots Scaling is so easy as to be not worth trying to change your output format.
23:42 armyofevilrobots we'll just scale whatever you send.
23:42 rue_shop2 hahah
23:42 rue_shop2 ok
23:42 rue_shop2 you should see what it does to fonts tho :)
23:45 armyofevilrobots I can only imagine.
23:46 rue_shop2 why do I always try to optimize pcb layouts till they would fit on the head of a pin? its forever a dissapointment cause after I succeed I have to add mounting holes which take up 99% of the final layout room
23:50 rue_shop2 hmmm
23:51 rue_shop2 smaller....
