[00:42:08] <Connor> Computer_Barf: Yes, it goes with it.
[00:42:50] <Connor> Put the Arbor in the freezer for a several hours.. then.. insert it into the chuck and tap it with a dead blow. or use a 2x4.
[00:43:23] <Connor> Computer_Barf: and Contracts on getting the mill
[00:43:32] <Connor> Was it new or used?
[00:49:58] <zeeshan|2> all i gotta say is
[00:50:07] <zeeshan|2> interstellar.. was actually pretty fin good
[00:50:19] <zeeshan|2> pretty damn scientifically accurate
[00:50:21] <zeeshan|2> minus the drama
[00:56:41] <Jymmm> zeeshan|2: how do oyu know the drama wasn't accurate?
[00:57:17] <zeeshan|2> lol
[00:57:23] <zeeshan|2> i guess it was to some degree
[00:57:25] <zeeshan|2> they got the timing right
[00:57:36] <zeeshan|2> the in blackhole event was all speculation
[00:58:03] <Jymmm> zeeshan|2: how do you know it wasn't accurate?
[00:58:18] <zeeshan|2> i guess i don't :)
[00:58:28] <Jymmm> zeeshan|2: otay panky!
[00:58:45] <zeeshan|2> it's one probable theory of a black hole :)
[00:59:00] <Jymmm> blak holes suck is another
[00:59:28] <zeeshan|2> we've observed blackholes eating light for dinner
[00:59:30] <zeeshan|2> and breakfast
[00:59:37] <zeeshan|2> pretty good evidence they eat :P
[00:59:54] <Jymmm> not necessarily
[01:00:26] <zeeshan|2> on a nother note
[01:00:35] <zeeshan|2> do you know einteins space-time fabric intrepration?
[01:00:46] <Jymmm> maybe they just et carbon and poop out diamonds and stuff?
[01:00:50] <zeeshan|2> thats true
[01:01:02] <zeeshan|2> then we can have cheap diamond lathe inserts
[01:01:03] <zeeshan|2> :D
[01:01:19] <Jymmm> shit inserts
[01:01:44] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15746739912/
[01:01:51] <zeeshan|2> i got most of my stuff mounted
[01:01:53] <zeeshan|2> non control stuff
[01:01:58] <Jymmm> Curious, do black holes poop like bunny turds?
[01:01:59] <zeeshan|2> i think the 3 fans is a bit overkill
[01:02:10] <zeeshan|2> Jymmm: poop opoop poop
[01:02:38] <Jymmm> many all the planets in the galaxy and just blak hole turn balls?
[01:02:43] <Jymmm> maybe*
[01:02:51] <Jymmm> turd*
[01:08:18] <zeeshan|2> lol
[01:34:27] <XXCoder> zeeshan|2: just watched it too
[01:34:30] <XXCoder> damn its hella gfood
[02:12:56] <zeeshan|2> XXCoder: yea man!
[02:13:03] <zeeshan|2> its so well done
[02:17:15] <archivist> hmm DNS and Bind on the shelf
[02:18:00] <archivist> are you allowed indoors on the carpet with that?
[02:18:49] <zeeshan|2> haha
[02:18:52] <zeeshan|2> thats such an old book
[02:19:05] <zeeshan|2> i think i bought it in 1998
[02:19:08] <zeeshan|2> or 199
[02:19:10] <zeeshan|2> 99
[02:19:57] <archivist> I got the 2001 ed :)
[02:19:57] <zeeshan|2> archivist: my gf asked me today
[02:20:06] <zeeshan|2> "how long will you have all your boxes in here?!?!"
[02:20:08] <zeeshan|2> im like
[02:20:10] <zeeshan|2> "a couple weeks haha"
[02:20:11] <zeeshan|2> :D
[02:20:22] <zeeshan|2> lemme snap a shot of what it looks like right now
[02:20:30] <zeeshan|2> i'd move it all to the garage, but that means i gotta heat it
[02:20:44] <archivist> I run DNS here :)
[02:21:20] <zeeshan|2> nice
[02:21:24] <zeeshan|2> i totally forgot what sin that book
[02:21:28] <zeeshan|2> i think i was trying to configure bind
[02:21:31] <zeeshan|2> to run a dns server
[02:22:00] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15560767500/
[02:22:02] <archivist> I run it hear at a customers and a friend has the third
[02:22:02] <zeeshan|2> disaster zone
[02:22:15] <zeeshan|2> archivist: cool :D
[02:22:36] <zeeshan|2> i left her some space
[02:22:40] <zeeshan|2> to access the dresser
[02:22:40] <zeeshan|2> lol
[02:22:53] <archivist> too much visible carpet error at line one
[02:23:08] <zeeshan|2> ?!?!
[02:24:59] <archivist> not enough stuph covering teh floor
[02:25:06] <zeeshan|2> haha
[02:25:18] <zeeshan|2> i hate working on carpet
[02:25:28] <zeeshan|2> because ifeel like ill statically discharge on something
[02:25:32] <zeeshan|2> i try to stay still :D
[02:26:12] <archivist> you could run an earth cable to the cases
[02:26:17] <Deejay> moin
[02:26:20] <zeeshan|2> where would it go to?
[02:26:22] <zeeshan|2> the wall plug?
[02:26:27] <archivist> yes
[02:26:36] <zeeshan|2> good idea
[02:27:04] <zeeshan|2> work has stopped for the night
[02:27:11] <zeeshan|2> i need a 23x23" mounting plate
[02:27:17] <zeeshan|2> i thought i had an extra one
[02:27:19] <zeeshan|2> but i cant find it
[06:58:43] <jdh> I have teh 1994 version
[07:08:09] <taiden> hey all
[07:13:42] <taiden> what do you guys think of the xylotex 3 axis kits?
[07:14:52] <taiden> i've always been a g540 user but i'm not a fan of 10 microsteps and the price is quite a bit more
[07:27:00] <jthornton> I prefer the G251X over the G540 for a low voltage stepper driver
[09:23:16] <CaptHindsight> http://www.washington.edu/news/2014/11/05/uw-study-shows-direct-brain-interface-between-humans/
[09:57:09] <CaptHindsight> here's a TI SOC with fast ARM cores, a decent GPU and PRU's http://linuxgizmos.com/beagleboard-x15-features-dual-core-cortex-a15-sitara/
[09:59:11] <CaptHindsight> I wonder if the BeagleBoard-X15 will priced high and only made in short runs like the Panda
[09:59:52] * jthornton finally got the entities from a dxf file into a python list
[10:00:08] <CaptHindsight> http://files.linuxgizmos.com/ti_am572x_block2.jpg
[10:00:10] <jthornton> now to find the matching xy points I think
[10:00:56] <CaptHindsight> http://files.linuxgizmos.com/ti_am572x_block1.jpg
[10:01:11] <pcw_home> powerVR GPU Yuck
[10:01:29] <ssi> jthornton: what are you working on?
[10:01:43] <CaptHindsight> yeah and will probably cost more than an x86 mini-itx board
[10:02:25] <jthornton> messing about with a wild ass idea to make a G code generator
[10:02:31] <jthornton> from a dxf file
[10:04:16] <ssi> I've been wanting to do something like that for awhile
[10:06:13] <jthornton> the hardest part was determining when I was at the end of an entity, I had to test for space space zero
[10:06:32] <jthornton> but ended up using if line == ' 0\r\n':
[10:06:42] <CaptHindsight> whats the current workflow with DXF? CAD --> DXF --> CAM --->Gcode
[10:07:03] <jthornton> dxf == cad
[10:07:25] <CaptHindsight> yes I was just representing the tool and it's output and input
[10:07:32] <jthornton> ok
[10:07:49] <jthornton> yea if it is my mill and no if it is my lathe usually
[10:07:53] <CaptHindsight> CAD --> CAM :)
[10:10:19] <jthornton> on my lathe I use ngcgui so I can skip the cam g code part
[10:12:29] <jthornton> ssi, you want the python I have so far?
[10:12:58] <jthornton> 70 lines to collect the entities from a dxf file
[10:15:23] <jthornton> I like this one lol "since light travels faster than sound, some people appear bright until they speak"
[10:32:12] <Tom_itx> jthornton the thing about that interpreter is handling things like pockets and multiple offset passes etc
[10:32:28] <JT-Shop> the next challenge is to sort the list by sequential start and end points I assume
[10:32:53] <JT-Shop> which interpreter?
[10:33:04] <Tom_itx> the one you're working on
[10:33:17] <Tom_itx> generator *
[10:34:10] <Tom_itx> you could do the profile but what about material removal up to the profile and things like lead in / out moves?
[10:34:19] <ssi> jthornton: yeah, I'd like to mess with it
[10:34:21] <ssi> probably won't be today tho
[10:34:29] <Tom_itx> sounds interesting though
[10:35:20] <JT-Shop> I'm thinking about plasma G code atm, but yes once you have all the entities you could do anything
[10:35:34] <Tom_itx> well that would be alot easier i suppose
[10:36:03] <Tom_itx> having the path with no tool offset direction etc would simplify it
[10:36:12] <JT-Shop> part 1 is done, reading the dxf file and extracting the LINE ARC and CIRCLE entities into a list of dicts
[10:36:52] <JT-Shop> to start you could draw the offset I suppose
[10:38:05] <JT-Shop> one thing that plasma cam does is read the layers so you can pick inside or outside offset for each layer
[10:38:08] <Tom_itx> have a look at eagle's gcode.ulp file
[10:38:26] <Tom_itx> it might help a bit
[10:38:33] <JT-Shop> what is it?
[10:38:35] <Tom_itx> i can post it if you don't have eagle
[10:38:44] <Tom_itx> eagle is a schematic / board program
[10:38:55] <JT-Shop> I don't think I have eagle any more
[10:39:02] <Tom_itx> i'll upload it
[10:39:07] <JT-Shop> olk
[10:40:07] <ssi> there's a mustang out flying around here today
[10:40:13] <ssi> not the same one that was up in kennesaw last weekend
[10:40:50] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/JT-Shop/
[10:40:50] <JT-Shop> full size P51?
[10:40:53] <ssi> yeah
[10:41:01] <Tom_itx> the gcodedrl is just for holes
[10:41:06] <Tom_itx> the other one does profiles
[10:42:31] <JT-Shop> thanks, I'll have a look at it in a bit... gluing up some corner trim for the shop siding
[10:42:48] <Tom_itx> np
[10:44:31] <renesis> jt-shop: neat book http://tom-itx.ddns01.com:81/~webpage/JT-Shop/HeatTreatingDataEBook.2011.pdf
[10:44:48] <Tom_itx> renesis he has that
[10:44:57] <Tom_itx> i uploaded it for him one day
[10:44:58] <renesis> i know its his link
[10:46:20] <Rab> Tom_itx, what does gcode.ulp do? Is it the same thing as pcb-gcode?
[10:46:33] <Tom_itx> pretty much
[10:48:14] <renesis> tom_itx: oh it was your link
[10:48:17] <Tom_itx> i've only used the drill one but heard others have used the profile ver
[10:48:19] <renesis> tom_itx: neat book
[10:48:23] <Rab> I'm looking for a way to plot Eagle paths straight to gcode, without isolation, to mill a positive rather than a negative (not for PCBs, naturally).
[10:48:40] <Tom_itx> you could look it over, it might do what you want
[10:48:48] <Rab> Yeah, I'll take a look.
[10:48:55] <Tom_itx> or mod it
[10:49:37] <renesis> rab: does it need to be eagle?
[10:49:46] <renesis> or you just want cam without paying
[10:49:54] <Rab> renesis, I just want cam without paying.
[10:49:55] <Tom_itx> eagle is free but limited
[10:49:59] <cpresser> Rab: export do .dxf (type 'run dxf')
[10:50:14] <renesis> rab prob has more than free eagle
[10:50:18] <cpresser> then use any cam to convert dxf to gcode
[10:50:25] <Rab> Yeah, I have the nonprofit license.
[10:50:37] <Rab> cpresser, ahh, thanks for the tip.
[10:51:09] <Rab> I use Inkscape now for 2D stuff, but I also have some faceplates and other vector art I did in Eagle that I'd like to mill.
[10:51:09] <Tom_itx> JT-Shop i also uploaded the dxf.ulp in case it might help explain parts of the other one
[10:51:14] <renesis> didnt cradek have some sort of autocad plugin
[10:51:20] <Tom_itx> i've not used dxf.ulp myself
[10:51:44] <Rab> I guess I could export PDF and import that to Inkscape.
[10:51:58] <renesis> inkscape wont eat dxf?
[10:52:06] <Rab> But if there's a way to do it straight from Eagle...
[10:52:08] <archivist> forget PDF
[10:52:49] <Rab> Oh wow, Inkscape totally does DXF!
[10:52:54] <renesis> rab: have you tried pcb-gcode with toolsize set to tiny and minimim thickness lines?
[10:53:04] <Rab> renesis, I haven't tried anything. ;)
[10:53:11] <renesis> even doing negatives, itd be doing paths on top of each other
[10:55:55] <ReadError> wow seems all of stonertronics from efnet has migrated here ;p
[10:55:57] <ReadError> j/k
[10:56:22] <Rab> renesis, that still doubles up on paths, which might not be desired behaviour depending on the material etc. It's the TTF problem: TrueType fonts define an outline, not a path, so if you want to engrave TTF you have to make two passes over the letter even if you reduce the area to 0.
[10:57:00] <renesis> so you make 4 paths over the letter
[10:57:13] <renesis> might be beneficial depending on material
[10:57:32] <renesis> http://www.gsimple.eu/features.html
[10:57:54] <renesis> this guy doesnt have any images of his program that i can find, bit scary
[10:58:09] <Rab> Might be, but it's also time-consuming. I've found engraving already takes a long time even if paths are optimized; plunges for each stroke, and so on.
[10:59:46] <renesis> needs moar g0
[11:00:50] <renesis> http://www.cambam.info/
[11:00:51] <Tom_itx> set the z return height low .050" etc saves time
[11:01:09] <Rab> renesis, I exported this design from Eagle -> PDF -> Inkscape -> Gcodetools and it ended up being like 40K lines. LinuxCNC sim took many minutes and kept dying in the job (just stopped moving). I definately need better CAM. ^_^
[11:01:09] <renesis> 40 functional sessions, 500 lines after, i kinda want to try that
[11:01:54] <Rab> Tom_itx, I do...to .050, actually!
[11:02:25] <renesis> you could just juarez mastercam
[11:02:29] <renesis> it works
[11:02:44] <Rab> Sure, but I'm trying to keep a Lunix toolchain.
[11:03:01] <XXCoder> yeah illegal is more fun :P
[11:04:14] <ReadError> cambam is great
[11:05:05] <renesis> cool
[11:07:52] <renesis> rab: cambam is only $150
[11:08:34] <Rab> renesis, pro small-business CNC dudes seem to love it...I could just take the easy way out.
[11:09:07] <renesis> its fully functional for free 40 times
[11:09:31] <Rab> CamBam, Mach3, done.
[11:09:35] <Rab> ;)
[11:09:43] <ReadError> did you just say the M word?
[11:09:44] <renesis> mach3 sucks
[11:10:08] <ReadError> cambam is good for 2.5D in particular
[11:10:15] <renesis> that shit would dwell the machine if you moved the mouse cursor too fast
[11:10:28] <Rab> Just kidding, I'm going to install Debian and try to get PyCAM or similar working.
[11:10:28] <renesis> readerror: thats mostly what i want
[11:10:40] <ReadError> renesis its great for that then
[11:10:44] <ReadError> the tabs are nice
[11:25:37] <Tom_itx> Rab i didn't make it past the 3rd one before i uninstalled it
[11:25:59] <Tom_itx> but i'm used to my pro cad cam package
[11:26:16] <Rab> Tom_itx, CamBam?
[11:26:20] <Tom_itx> yeah
[11:26:27] <Tom_itx> i loaded it to help someone with a post
[11:40:24] <somenewguy> PetefromTn_: did you write the faceing program in python?
[11:48:01] <Rab> All right, got PyCAM instlled.
[11:57:11] <jthornton> wow converting from a dxf arc to G code will be fun
[11:57:42] <XXCoder> how good is pucam?
[11:57:44] <XXCoder> py
[11:57:49] <archivist> better to make a drawing direct in gcode program :)
[11:57:59] <skunkworks> jthornton: what are you working on?
[11:58:33] <jthornton> just messing around reading a dxf file then converting it to G code
[11:58:56] <jthornton> I've got reading the dxf into a list of dicts down pat
[11:59:08] <jthornton> lines are easy
[11:59:42] <jthornton> here is how the arcs are stored http://pastebin.com/Uh8y3c9u
[12:00:53] <skunkworks> neat
[12:01:08] <skunkworks> have you looked at dxf2gcode?
[12:01:25] <skunkworks> it looks to be writen in python
[12:02:09] <jthornton> yes, but it is real complicated
[12:02:18] <skunkworks> the little I have played with it - it looks promisning. - it does things like combine profile segments and allows you to change direction and add cutter comp.
[12:02:37] <jthornton> I've never got it to work
[12:02:41] <skunkworks> oh
[12:03:32] <skunkworks> http://electronicsam.com/images/KandT/testing/Screenshot%20from%202014-10-20%2023:05:22.png
[12:03:52] <skunkworks> http://electronicsam.com/images/KandT/testing/Screenshot%20from%202014-10-20%2023:08:50.png
[12:04:09] <jthornton> neat
[12:04:57] <jthornton> this is the code to read the dxf into a list of dicts http://pastebin.com/uhN1QHdp
[12:05:01] <jthornton> not long at all
[12:10:27] <skunkworks> neat - my python that I write looks more like vb...
[12:10:32] <skunkworks> sorry
[12:10:43] <jdh> use cradek's realize format for feeds, tools, etc?
[12:11:47] <skunkworks> you pick the tool per profile (it is part of dxf2gcode) and the tool dictates the feed.
[12:11:52] <skunkworks> iirc
[12:13:30] <Tom_itx> jthornton, i added the dxf.ulp for you too
[12:13:37] <jthornton> hmm seems like all arcs are stored CCW direction for start and end
[12:13:41] <jthornton> thanks Tom_itx
[12:13:42] <Tom_itx> might help with arcs...
[12:13:45] <Tom_itx> dunno
[12:22:43] <PetefromTn_> Jeez man...
[12:22:53] <PetefromTn_> I got a little dilemma here now it seems
[12:23:15] <PetefromTn_> I wanted to get this CNC lathe badly
[12:23:39] <PetefromTn_> so I had to sell off my 12x36 manual lathe to get it.
[12:23:59] <PetefromTn_> Most of the work I do for customers is on the CNC mill
[12:24:27] <PetefromTn_> but since I sold the damn lathe I have had two different people contact me about making some cool parts that would sort of be better made on the lathe
[12:24:46] <PetefromTn_> Either that or they would require a BUNCH of custom 3d toolpathing on the mill
[12:25:16] <PetefromTn_> I am not all that great with the 3d stuff yet I can do it but these are fairly elaborate pieces
[12:25:25] <archivist> check the log, I may have mentioned dont get rid of a manual lathe :(
[12:25:33] <somenewguy> can you compare PyCAM to HeeksCNC?
[12:25:45] <PetefromTn_> so I gotta decide to take on the work or pass until the CNC lathe is here
[12:25:49] <PetefromTn_> er working rather
[12:26:05] <PetefromTn_> or try to do it on the CNC with the more advanced 3d toolpaths
[12:26:09] <archivist> somenewguy, not really completely different methods
[12:26:20] <somenewguy> ok, I haven't ever looked at PyCAM
[12:26:35] <PetefromTn_> yeah I know I should have not sold the lathe but I had to or I would never have gotten the CNC lathe here
[12:26:50] <somenewguy> oh does anyone in here konw how to make a super simple python GUI? or really any gui that will call a python function?
[12:27:00] <PetefromTn_> I wish I knew someone who was REALLY good at 3d toolpathing locally
[12:27:00] <somenewguy> I essentially want to make a calculator, and only spend an hour on it
[12:27:10] <somenewguy> PetefromTn_: who dosnt lol
[12:27:28] <PetefromTn_> I guess I need to become that person or pass LOL
[12:27:34] <somenewguy> although writing stuff for NGCGUI has been fun
[12:27:53] <somenewguy> I have a pretty stellar ramp in routine in the works that should make my paths more effecient
[12:28:22] <somenewguy> do you mean 3d toolpathing from a model, or the theory behind it?
[12:29:12] <PetefromTn_> I mean I can create a 3d model of the part I want, I usually do that anyways even if it is not a real 3d part
[12:29:41] <PetefromTn_> but I am not that experienced with programming the toolpaths especially the finishing paths that are required for that nice surface finish
[12:30:06] <PetefromTn_> and these parts are mostly aesthetic in nature so they have to look damn good.
[12:30:40] <PetefromTn_> I may be able to borrow a lathe from a friends shop to finish them but I gotta check and see. Most of the work I can do on the CNC mill.
[12:31:22] <PetefromTn_> Damn I cannot wait to have that CNC lathe running so this will be a simple process. There are a lot of parts I can make that will be profitable.
[12:32:01] <Tom_itx> even if you get a cnc lathe you will not be able to replace a manual lathe.
[12:32:15] <PetefromTn_> Just need to find some more Gold Pressed Latinum to be able to purchase the motors and drives etc. etc... Oh well at least it is here and I have something to work with.
[12:32:23] <PetefromTn_> how do you figure?
[12:32:56] <Tom_itx> there are parts i can make on a manual lathe quicker and more efficient than on a cnc
[12:33:00] <archivist> I use the manual lathes more than cnc
[12:33:05] <Tom_itx> i can't repeat it easily but i may only need one
[12:33:20] <PetefromTn_> that is precisely why I sold the manual lathe.
[12:33:28] <Tom_itx> but now you need it
[12:33:38] <PetefromTn_> Beleive me I see your point I have been turning manually for a LONG time.
[12:33:49] <PetefromTn_> yeah because the CNC lathe is not working yet
[12:34:22] <PetefromTn_> I have turned literally thousands of parts on manual lathes over the years.
[12:35:04] <PetefromTn_> and the lathe I have here once CNC will be kind of something in between a full blown turning center and a manual lathe which is why I chose it.
[12:35:34] <PetefromTn_> I will probably get another manual lathe at some point
[12:35:55] <PetefromTn_> but I am very excited about seeing the new CNC lathe working and making consistent parts.
[12:37:08] <archivist> a new to me lathe arrived here a few weeks ago, been very useful
[12:37:24] <PetefromTn_> Oh well I gotta contact the customer with a decision about this. I may see what kind of time frame he is under and then decide if I can put together a program for it in 3d millling or not.
[12:37:26] <PetefromTn_> nice
[12:37:31] <PetefromTn_> what kind of lathe did you get?
[12:37:56] <archivist> http://www.collection.archivist.info/searchv13.php?searchstr=lathe+lorch
[12:38:09] <archivist> no leadscrew :)
[12:38:25] <archivist> best for hand turning curves
[12:38:44] <PetefromTn_> almost looks like a wood lathe actually
[12:39:39] <archivist> it ic a clockmakers sort of lathe where you can change topslide to rest quickly
[12:40:06] <PetefromTn_> I can see where making delicate shapes that small it would come in handy for hand turning stuff and polishing tho.
[12:40:31] <PetefromTn_> I used to do things like that on my manual I sold.
[12:40:57] <PetefromTn_> I had some shop built radius turning tools and arc tools I fabricated and would finish with emery cloth and polishing rouge etc.
[12:43:43] <archivist> this is my grab of the ebay page http://www.collection.archivist.info/archive/mirror/Lorch/lorch.html
[13:10:50] <somenewguy> pete, aside from manual writing of gcode, what are you currently doing to get a toolpath?
[13:17:14] <Rab> Anybody have an opinion on bang for the buck of no-name chinese linear bearings/rail on eBay vs used/surplus THK/Thomson/etc? The name-brand stuff isn't that much more expensive...
[13:18:59] <Rab> And robust components, partially worn, seem like they might provide a better value over something that wears in quickly and poorly.
[13:19:23] <XXCoder> sometimes it really dont make all that much difference
[13:19:34] <XXCoder> but dunno when that's true
[13:26:05] <somenewguy> depends on what you are using it for I guess? a bad bearing can never be made better, buta worn brand name can be replaced piecemeal as you decide you need more accuracy I guess?
[13:26:10] <XXCoder> pop a lsd https://www.youtube.com/watch?v=kBMArUuHXDI
[13:28:39] <XXCoder> somenewguy: if get chinese shit then buy new bearings
[13:28:43] <XXCoder> american made ones
[13:38:06] <XXCoder> oh https://www.youtube.com/watch?v=GLZdnR7Nkus is what happens after that lsd trip lol
[13:39:28] <XXCoder> oh it cut at end dammit
[13:41:25] <JT-Shop> interesting a dxf file line start point is the end farthest from the WCS center
[14:12:39] <Computer_Barf> john Connor are you out there?
[14:13:39] <Connor> I dunno about John Connor.. But.. I'm here for a few minutes.
[14:14:48] <Connor> Computer_Barf: What's up?
[14:15:05] <Computer_Barf> did you go with a nema 34 on your z axis?
[14:15:22] <cmorley> somenewguy: gladevcp has a calculator widget. gscreen can make a simple GUI quickly and you can add python calls.
[14:15:40] <Connor> No. I stuck with a 570oz nema 23's all away around. (direct drive)
[14:16:04] <Computer_Barf> Im talking to a guy that makes kits , he can make me a z axis that can fit nema 34 , but already has one for nema 23 ready
[14:16:34] <Connor> Did you buy your G0704 new, or used? and did you see my comment about the arbor and the drill chuck ?
[14:17:13] <Computer_Barf> no i didn't see your response, its used
[14:17:16] <Computer_Barf> well
[14:17:38] <Computer_Barf> used might not be fair , its a rediculusly unused, used machine
[14:17:46] <Connor> Put the arbor in the freezer for several hours... then remove it and insert it into the juck and smack it good with a dead blow or 2x4
[14:18:30] <Computer_Barf> Nice that makes sense.
[14:19:18] <Computer_Barf> i got it for 900 bucks, with a clamping kit, collet set, vise, bunch of other things
[14:19:40] <Connor> that nice.. and no shipping too.
[14:20:10] <Connor> Looking at it.. does it have 4 bolts that hold the head to the Z-Zaddle ? or just 2 ? (Center and lower)
[14:20:20] <Computer_Barf> yeah. I can't likely do warrenty stuff but I plan on completely invalidating that anyway
[14:20:31] <Computer_Barf> 4
[14:20:47] <Computer_Barf> you mean in the lower back of the machine right?
[14:21:45] <Computer_Barf> man i had no idea how difficult it was going to be to move it
[14:21:49] <Connor> no. the head itself.
[14:21:54] <Connor> the spindle.
[14:22:04] <Computer_Barf> oh i would have to go look
[14:22:24] <Computer_Barf> brb
[14:22:30] <Connor> older versions only had 2 (1 in center and lower) bolts to hold it on.. newer ones have 3 (in circle pattern) + 1 in center
[14:25:00] <somenewguy> dude I just took a trip down memory lane
[14:25:05] <somenewguy> anyone else use CADKEY back in the day?
[14:25:33] <somenewguy> they still exist and do 2 and 3 axis tool path generation
[14:26:49] <CaptHindsight> Rab: so far any used/surplus bearings in good shape are better than anything I've gotten made in China. Not sure when they will catch up on quality.
[14:27:28] <somenewguy> cmorley: interesting, I'll earmark that for later
[14:27:47] <somenewguy> I just took a stab with tkinter, got my feet halfway under me but decided I don't have the time right now
[14:27:55] <CaptHindsight> Rab: if it made in Taiwan then it's generally on par with western or Japanese suppliers
[14:28:00] <somenewguy> was hoping for 1-2 hours to finish what I need, that smells like a full afternoon lol
[14:31:08] <Computer_Barf> Connor: oh you mean like , bolts to take the spindle off? I didn't take it apart to move it. I can see the state of the machine was manufactured in 2013
[14:31:35] <Connor> okay.. It should have what we call the 3-bolt mod.
[14:32:11] <Computer_Barf> ill check into that when my batteries recharge, yesterday was a long day
[14:32:37] <Computer_Barf> i hauled the thing in the back seats of a 4 door
[14:32:48] <Computer_Barf> didn't have a truck or engine crane
[14:33:11] <Connor> How did you all load it in? I hope you didn't lift using the table.
[14:33:47] <Computer_Barf> no it was done with a board , bunch of people , lots of patience
[14:33:47] <Connor> Could warp or bend the table. :(
[14:33:56] <Connor> OKay. GOOD! :)
[14:34:03] <Connor> Alright.. I have to run for a while.
[14:34:07] <Connor> Shopping and lunch.
[14:34:16] <Computer_Barf> cool , laters.
[14:43:26] <zeeshan|2> anyone have experience with case fans that are 230vac or 115vac
[14:43:29] <zeeshan|2> impedance protected
[14:54:09] <CaptHindsight> protected against impedance?
[14:54:22] <zeeshan|2> yea
[14:54:25] <zeeshan|2> im wondering if they need to be fused
[14:55:30] <CaptHindsight> http://en.wikipedia.org/wiki/Electrical_impedance
[14:57:30] <zeeshan|2> CaptHindsight: i know what impedance is
[14:57:36] <zeeshan|2> just need to know if they neewd to be fused
[14:57:39] <zeeshan|2> its a bit annoying because i have 3 fans
[14:57:43] <zeeshan|2> all 230vac
[14:57:55] <CaptHindsight> are fans that use the term impedance UL listed?
[14:57:56] <zeeshan|2> which will mean i'll need 3x 3 pole fuses to protect them
[14:57:57] <XXCoder> interesting http://hackaday.com/2014/11/07/printing-in-metal-with-a-mig-welder/
[14:58:04] <Rab> https://www.ia.omron.com/support/faq/answer/45/faq01551/index.html
[14:58:47] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15126376003/
[14:58:49] <CaptHindsight> zeeshan|2: I'm also poking fun at the bastardized use of the term impedance with the fans
[14:58:49] <Rab> Sounds like UL-listed impedance-protected fans can be safely operated in a locked condition for 15 days.
[14:58:57] <zeeshan|2> thats the fan
[14:59:29] <zeeshan|2> CaptHindsight: well they say impedance
[14:59:34] <CaptHindsight> after 15 days they explode violently
[14:59:34] <zeeshan|2> cause an AC you deal with complex terms
[15:00:14] <zeeshan|2> an = with
[15:00:27] <zeeshan|2> im kind of an idiot
[15:00:31] <zeeshan|2> i thought these were 115VAC fans
[15:00:33] <CaptHindsight> fuses are there to protect the conductors
[15:00:43] <zeeshan|2> CaptHindsight: i understand
[15:00:48] <zeeshan|2> but you can use fuses to protect the device too
[15:01:02] <zeeshan|2> so it doesnt go on fire
[15:01:07] <zeeshan|2> which is what im wondering right now
[15:01:11] <zeeshan|2> if the fans all need to be fused
[15:01:25] <zeeshan|2> it adds a shitload of fuse holders :{
[15:01:44] <CaptHindsight> fs you want to size some fuses to limit the current below what the impedance of the fans have ...
[15:01:55] <CaptHindsight> fs/if
[15:02:11] <zeeshan|2> hmm i'm confused
[15:02:17] <zeeshan|2> these fans are .10A draw
[15:02:22] <zeeshan|2> so i was going to put .5A draw fuses
[15:02:32] <CaptHindsight> the fans are supposed to protect themselves from fire if they lock up
[15:02:40] <zeeshan|2> so say a coil shorted inside the motor of the fan
[15:02:42] <zeeshan|2> then the fuse would blow up
[15:03:03] <Rab> zeeshan|2, that sounds absolutely insane. You were talking about fusing your task light, too. Why not run all these accessories to a small breaker?
[15:03:03] <zeeshan|2> if i rely on sizing the fuse for the conductor (14 awg in this case)- that would be 15A
[15:03:15] <zeeshan|2> rabb they are on a main fuse of 15A
[15:03:21] <zeeshan|2> but im afraid that say for some reason something happens to the fan
[15:03:27] <CaptHindsight> a sort to its coil would change their impedance
[15:03:27] <zeeshan|2> ie coil shorts
[15:03:34] <zeeshan|2> the fan will need to see 15A before the fuse goes
[15:03:40] <zeeshan|2> and that might be enough to set it on fire
[15:03:52] <CaptHindsight> sure, if a coil was shorted
[15:03:52] <zeeshan|2> instead of say if i had a 0.5A fuse there
[15:04:47] <CaptHindsight> to really find out what size to use you'll have to decide on how low an impedance the fan will have based on the theoretical short and how hot it will get
[15:05:10] <Rab> zeeshan|2, maybe you need some kind of overtemp/smoke/fire detection in your cabinet.
[15:05:17] <zeeshan|2> rab like
[15:05:19] <zeeshan|2> *lol
[15:05:22] <zeeshan|2> are you trolling me
[15:05:27] <zeeshan|2> cause i'm being a safety nazi
[15:05:45] <CaptHindsight> worst case would be a short right at the start of the windings
[15:06:26] <CaptHindsight> how much current will pass through the conductors, and how hot will they get
[15:07:15] <zeeshan|2> CaptHindsight: why cant you just throw a 0.5A fuse
[15:07:19] <zeeshan|2> for a 0.1A max draw fan?
[15:07:38] <zeeshan|2> so that it doesn't have to see 15A of current draw before the main fuse pops
[15:07:51] <CaptHindsight> why not a 0.2A or 0.3A?
[15:08:00] <zeeshan|2> cause of inrush currents
[15:08:01] <LeelooMinai> Hmm, what should I do with ENBL+/- on stepper drivers and 7i76? Stepper channels do no seem to have outputs for them.
[15:08:08] <CaptHindsight> are you just picking random vales?
[15:08:09] <zeeshan|2> they usually say 125% of fla
[15:08:35] <zeeshan|2> er
[15:08:40] <zeeshan|2> i should be using a .125A fuse then
[15:08:45] <Rab> zeeshan|2, I'm serious. I don't mean to minimize your concern, but I've never seen equipment constructed in this way. Trying to account for every theoretical fire hazard, you're bound to miss something. A global means of fire detection seems warranted.
[15:09:07] <zeeshan|2> rab so youre b asically say
[15:09:11] <zeeshan|2> plug the fans in
[15:09:13] <zeeshan|2> and call it a day :P
[15:09:34] <zeeshan|2> or if i m worried, go with some crazy fire detection :P
[15:09:37] <CaptHindsight> but then his OCD will kick in
[15:09:41] <Rab> Plus, there could well be fire-hazard failure modes which don't blow the fuse. What then?
[15:10:06] <zeeshan|2> rab like what?
[15:10:14] <CaptHindsight> I think his garage has a Halon system
[15:10:18] <zeeshan|2> fyi
[15:10:23] <zeeshan|2> the reason i'm worried about fires is because
[15:10:26] <zeeshan|2> my old car went on fire
[15:10:30] <Linuxcncnube> Looking for assistance with Dell Inspiron 600m on latency. Huge spike every 16 seconds, great otherwise. New to Debian, thought from RTFM attempts it might be SMI, but it seems to happen at a much shorter interval than I'd expect from reading.
[15:10:35] <zeeshan|2> and now that i think about it, it was completely factory wiring.
[15:10:40] <zeeshan|2> and the fuse failed to go off
[15:10:45] <zeeshan|2> while the wires chaffed away on metal
[15:10:51] <zeeshan|2> and the harness cauight on fire
[15:11:07] <CaptHindsight> Linuxcncnube: did you try all the BIOS settings and kill all power management?
[15:11:45] <Linuxcncnube> I didn't find any power management settings in the bios. Phoenix bios version A16 if that helps
[15:11:46] <CaptHindsight> Linuxcncnube: SMI has no regular interval, it could be every second or once a year
[15:12:07] <CaptHindsight> yeah DEll trims out most settings
[15:12:15] <zeeshan|2> rab
[15:12:20] <zeeshan|2> i'm looking at my house 120VAC fan
[15:12:22] <zeeshan|2> it has no fuse in it :P
[15:12:35] <CaptHindsight> Linuxcncnube: some BIOS are just not suited for RTAI
[15:12:56] <zeeshan|2> LeelooMinai: arent you stepper drives enabled normally?
[15:12:57] <LeelooMinai> I guess I could leave ENBL +/- disconnected, but maybe there's some merit to disable drivers from linuxcnc (?)
[15:13:02] <zeeshan|2> when you power them
[15:13:24] <LeelooMinai> zeeshan|2: Yes, I just wonder if there's some plus of having control over them
[15:13:32] <Rab> Linuxcncnube, try pulling the battery and see if the issue changes or disappears.
[15:13:34] <zeeshan|2> yes there is
[15:13:42] <zeeshan|2> when you hit the machine power off button in linuxcnc
[15:13:45] <zeeshan|2> you can have them disabled
[15:13:53] <zeeshan|2> but it's really not failsafe
[15:14:02] <zeeshan|2> cause asap you remove power from 7i77
[15:14:06] <zeeshan|2> it'll go back to enabled :P
[15:14:36] <CaptHindsight> Linuxcncnube: DELL treats thei buyers like they are nothing but trouble so they minimize the possibility for users causing their support wasted time
[15:14:36] <LeelooMinai> But in this case where could I connect it? To field IO instead?
[15:14:55] <zeeshan|2> no
[15:15:01] <zeeshan|2> for my case it was ena + and gnd
[15:15:11] <zeeshan|2> but i think in your case it will be ena - and...
[15:15:13] <zeeshan|2> lemme see the manualk
[15:15:17] <LeelooMinai> On 7i76?
[15:16:19] <LeelooMinai> There are channels for steppers that have 5V+ GND step -/+ dir -/+, but no enable
[15:16:39] <zeeshan|2> yea wow
[15:16:40] <zeeshan|2> its different
[15:16:42] <zeeshan|2> i thought it was similar
[15:17:32] <LeelooMinai> Hmm, maybe I could use gnd/ +5V for that
[15:17:35] <zeeshan|2> looks like you'll need to pwoer one of your field i/o drivers
[15:17:35] <zeeshan|2> with 5v
[15:17:50] <zeeshan|2> LeelooMinai: that would disable your drives all the time then
[15:17:52] <zeeshan|2> i dont think its switched
[15:18:14] <zeeshan|2> are you talking about +5VP?
[15:18:15] <LeelooMinai> A, right, the enable disables when powerd
[15:18:33] <LeelooMinai> Since disconnected it's on
[15:18:37] <zeeshan|2> yes
[15:18:46] <zeeshan|2> its retarded
[15:18:54] <zeeshan|2> i did read that you can change something in the drives
[15:18:56] <zeeshan|2> to make it the opposite
[15:19:16] <LeelooMinai> I think I will just leave it unconnected
[15:19:30] <LeelooMinai> I have relay on the PSU anyways
[15:19:33] <zeeshan|2> just make sure you have a way to kill the power to the
[15:19:35] <zeeshan|2> there u go :P
[15:19:52] <LeelooMinai> oki then, thx
[15:19:53] <zeeshan|2> LeelooMinai: the thing i hav ebeen arguing about in here is
[15:20:01] <zeeshan|2> you dont want to rely on that safety relay all the time
[15:20:09] <zeeshan|2> it's a harsh way of killing power to your stepper drives
[15:20:13] <zeeshan|2> especially when they're under power
[15:20:20] <Linuxcncnube> <Rab>, you nailed it, the battery has been out for about 2 minutes, jitter looks great. Any permanent solution ideas that will allow the battery to stay in?
[15:20:26] <zeeshan|2> the enable is a much "softer" method
[15:20:33] <zeeshan|2> say you're about to detect a crash
[15:20:38] <zeeshan|2> you'd want to disable the drives first
[15:20:50] <zeeshan|2> and if for some odd reason, the drives don't want to disable (unlikely)
[15:20:53] <zeeshan|2> then you press e-stop
[15:21:10] <zeeshan|2> pressing e-stop means you also lose your position
[15:21:24] <zeeshan|2> (if you had feedback)
[15:21:33] <LeelooMinai> Right, well, not sure if it's doable in software, but maybe I could use spare step channel to control emable?
[15:21:37] <LeelooMinai> enable
[15:21:43] <zeeshan|2> use one of your field i/o
[15:21:44] <LeelooMinai> Using step or dir - not sure
[15:21:57] <LeelooMinai> I have 12V there though
[15:22:21] <zeeshan|2> thats okay
[15:22:33] <LeelooMinai> Not sure if driver can take that - it's probably just opto there with a resistor to limit current, could work
[15:22:34] <zeeshan|2> if you go to the field power connector portion in the manual
[15:22:43] <zeeshan|2> you'll see thheres 4 pins for field power
[15:22:48] <zeeshan|2> ugh nm
[15:22:52] <zeeshan|2> they're 8-32V
[15:22:56] <zeeshan|2> so you're SOL!! :P
[15:23:11] <LeelooMinai> well, not necessarily as I wrote:)
[15:23:31] <zeeshan|2> i guess i'd ask pcw :P
[15:23:35] <LeelooMinai> I could add additional resistor there to limit current from 12V
[15:24:06] <zeeshan|2> i dont know how resistors work in that situation :P
[15:24:17] <zeeshan|2> (with a transistor)
[15:24:34] <LeelooMinai> I think the inputs on the driver are just inputs to optocouplers. So basically infrared diodes that have resistor in series
[15:25:06] <zeeshan|2> you know more electronics than me
[15:25:08] <zeeshan|2> knowing me
[15:25:21] <LeelooMinai> they are current driven, so as long as I limit it, they can be driven with whatever voltage - that's just my guess, but I could verify it if I open the drivers I guess
[15:25:27] <zeeshan|2> i'd prolly just pass the 12v output signal through a coil
[15:25:35] <zeeshan|2> and on the switch side of the relay have the 5v :D
[15:25:57] <LeelooMinai> That's kind of overcomplicated solution though:)
[15:26:00] <zeeshan|2> hahah :D
[15:26:11] <zeeshan|2> if youve been folllowing the fan conversation
[15:26:15] <zeeshan|2> i like to overcomplicate things :(
[15:26:28] <zeeshan|2> bloody engineering
[15:26:44] <zeeshan|2> "if you aren't comfortable with something, OVER ENGINEER IT!!"
[15:27:22] <LeelooMinai> Finding a good balance that will work should be preferable:)
[15:28:02] <LeelooMinai> But I wonder why 7i76 does not have those driver disable outputs...
[15:28:11] <LeelooMinai> If there's some reason for it
[15:28:42] <LeelooMinai> I guess I will leave it for now and maybe the "mesa magic man" will know
[15:29:34] <zeeshan|2> haha
[15:29:50] <zeeshan|2> CaptHindsight + Rab
[15:29:52] <zeeshan|2> fu guys!
[15:29:55] <zeeshan|2> im putting a 0.2A fuse!!!
[15:30:04] <zeeshan|2> <3
[15:30:50] <zeeshan|2> if i had 2 damn fans
[15:30:56] <zeeshan|2> i could put them in series
[15:31:11] <zeeshan|2> but it had to be 3 :(
[15:33:49] <pcw_home> Mesa doesn't have drive disables because its a bad way of doing things (some servo drive have this and thats really insane)
[15:34:09] <LeelooMinai> pcw_home: So what is the good way?
[15:34:31] <pcw_home> a broken wire or wire shorted to ground should not enable a drive
[15:35:24] <pcw_home> with step drives you can use a spare Step/dir output as a 5V Disable signal if you wish
[15:36:22] <LeelooMinai> pcw_home: You think it's better than just to leave them enabled all the time?
[15:37:10] <pcw_home> possibly, it adds another layer of safety
[15:37:28] <LeelooMinai> ok, thx then - I was not sure if I will be able to reconvigure spare channel for this
[15:38:30] <pcw_home> you would want to chose the output polarity that defaults to disabled at power on and watchdog bite
[15:38:49] <zeeshan|2> LeelooMinai: you have the keling drives right?
[15:39:23] <pcw_home> all IO pins can be GPIO so if dont have all 5 stepgens enabled on a a 7I76, the free ones can be used as outputs
[15:40:20] <LeelooMinai> zeeshan|2: No, some Chinese wantai ones - but probably similar/clones
[15:40:51] <LeelooMinai> Ok, great
[15:41:17] <CaptHindsight> zeeshan|2: how about a 15 day time delay fuse?
[15:41:26] <zeeshan|2> CaptHindsight: !!!
[15:41:46] <zeeshan|2> CaptHindsight: i realize that if i somehow put these fans
[15:41:48] <zeeshan|2> in parallel or series
[15:41:50] <CaptHindsight> fan blade watchdog
[15:41:54] <zeeshan|2> i might be able to tie them to 1 fuse
[15:42:11] <renesis> genius, zeeshan|2
[15:42:19] <zeeshan|2> like with 2 fans its easy
[15:42:21] <zeeshan|2> i just put em in parallel
[15:42:23] <CaptHindsight> probably in parallel
[15:42:26] <zeeshan|2> and hook em up with 115vac
[15:42:28] <zeeshan|2> instead of 230vac
[15:42:31] <zeeshan|2> and it'll draw same current
[15:42:33] <pcw_home> motors in series is never a good idea
[15:42:33] <renesis> why cant you put three
[15:42:35] <zeeshan|2> but having 3 is where it confuses
[15:42:40] <renesis> in parallel
[15:42:45] <renesis> why does it confuses
[15:42:48] <zeeshan|2> renesis: it'll draw too much current at 115VAC
[15:42:57] <renesis> what kind of fans are these?
[15:43:05] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15126376003/
[15:43:11] <zeeshan|2> pcw_home: why
[15:43:23] <CaptHindsight> how about 2 230VAC motors in series?
[15:43:38] <zeeshan|2> CaptHindsight: id like to run them off 115VAC
[15:43:42] <renesis> theyre 230v .1A
[15:43:49] <CaptHindsight> with a center tap to neutral
[15:43:50] <renesis> so at 120v theyre prob .05A
[15:43:51] <zeeshan|2> thats why i wanna put em in parallel
[15:44:01] <renesis> so three in parallel is 0.15A
[15:44:03] <CaptHindsight> and then make them 115VAC motors :)
[15:44:05] <renesis> whats the issue?
[15:45:04] <CaptHindsight> what size fuse to use for 100ma 115VAC impedance protected fans?
[15:45:23] <renesis> three in parallel?
[15:45:40] <renesis> i dunno, 500mA normal speed
[15:45:58] <zeeshan|2> .15A = burned motor coils? :p
[15:46:02] <zeeshan|2> thats over drawing em by 50ma
[15:46:04] <renesis> what?
[15:46:09] <zeeshan|2> driving
[15:46:14] <renesis> no each draws 50mA
[15:46:19] <renesis> wtf overdriving
[15:46:22] <zeeshan|2> oh duh
[15:46:30] <renesis> im an idiot?
[15:46:56] <renesis> good luck overdriving them at half rated voltage
[15:47:06] <renesis> more likely to stall them and burn them out
[15:47:09] <zeeshan|2> you know whats throwing me off?
[15:47:14] <zeeshan|2> im thinking of them as induction motors
[15:47:16] <renesis> take about 1 fan and 1 minute to test that
[15:47:27] <renesis> they might be who knows
[15:47:28] <zeeshan|2> a 230VAC induction motor cant be wired to 115VAC
[15:47:38] <zeeshan|2> cause it'll draw double the current
[15:47:39] <renesis> prob a rectifier and a regular hall sensor motor
[15:48:07] <zeeshan|2> why does it draw double the current in the induction motor case?
[15:48:27] <renesis> because itll go half the speed and the current draw depends on the magnets switching before the inductance lets much current pass through
[15:48:31] <renesis> these might do the same thing
[15:48:49] <zeeshan|2> easy way to test this would be hook ammeter
[15:48:53] <zeeshan|2> and check out how much its drawing?
[15:48:59] <renesis> no
[15:49:13] <renesis> you dont trust ameters with anything not a sine wave or DC
[15:49:23] <renesis> true RMS doesnt mean from DC to light
[15:49:28] <zeeshan|2> this isnt a sine wave?
[15:49:42] <renesis> anyone who thinks so is an idiot they usually roll off under 200hz
[15:50:12] <renesis> zeeshan|2: current wont be if it doesnt have perfect power factor correction
[15:50:22] <renesis> use a sense resistor and an oscope
[15:50:28] <zeeshan|2> i dont have a scope
[15:50:28] <zeeshan|2> :P
[15:50:32] <renesis> then integrate the area under the wave form
[15:50:37] <renesis> use simple shapes, gets close
[15:50:52] <renesis> then just use a 1A fuse and get on with your life
[15:50:58] <renesis> if the fans burn. buy 120VAC ones
[15:51:13] <zeeshan|2> i have some 115vac ones
[15:51:20] <zeeshan|2> but theyre all different ratings
[15:51:23] <renesis> just take a fan and plug it into 120VAC and if after an hour its not fucked up hot, youre prob okay medium term
[15:51:26] <zeeshan|2> meaning faked up airflow
[15:51:37] <zeeshan|2> i hokoed it up for a few mins already
[15:51:39] <zeeshan|2> it wasnt f'ed
[15:51:41] <zeeshan|2> didnt get hot
[15:51:45] <renesis> you have your shit laid out so airflow is all turbulent anyway
[15:52:00] <renesis> few minutes isnt enough to saturate the magnets and housing
[15:52:04] <renesis> you need like an hour
[15:52:22] <renesis> then you need to smell for enamel wire, if you can smell burnt coil dont use those at 120vac
[15:52:35] <renesis> if you cant smell anything, its fine
[15:52:37] <zeeshan|2> or i can just hook em up to 230VAC :P
[15:53:11] <renesis> i dont like ac fans
[15:53:14] <renesis> they remind me of urmom
[15:53:43] <zeeshan|2> i justr checked with the ammeter
[15:53:48] <zeeshan|2> theyre drawing .1A at 115VAC
[15:54:13] <zeeshan|2> gonna check @ 230vac
[15:54:15] <renesis> because lower voltage but lower speed so its a wash
[15:54:24] <renesis> use a 500mA normal blow fuse
[15:54:32] <renesis> turn it on an off like a dozen times
[15:54:47] <renesis> if it blows, put a slow blo, move on with life
[15:56:12] <zeeshan|2> there goes the theory of 50mA at 115vac
[15:56:18] <zeeshan|2> at 230vac its also drawing .1A
[15:56:23] <zeeshan|2> so either my ammeter is inaccurate
[15:56:32] <zeeshan|2> or its being an induction motor
[15:56:35] <zeeshan|2> =p
[15:57:10] <zeeshan|2> gonna just hook em up to 230vac
[15:57:11] <zeeshan|2> and call it a day
[15:58:26] <zeeshan|2> so since hteyre drawing .1A each, can't i just put them in parallel and put em on a .5A fuse
[15:58:30] <zeeshan|2> so if one of the fan shorts
[15:58:34] <zeeshan|2> it'll still pop the fuse
[15:58:44] <renesis> jezus fuck do you have nme on ignore again or what
[15:58:45] <zeeshan|2> cause its current draw will try to go to infinity?
[15:58:53] <CaptHindsight> heh
[15:59:14] <zeeshan|2> ren i'm not talking to you anymore
[15:59:20] <renesis> haha
[15:59:21] <zeeshan|2> your advice is meaningless
[15:59:25] <zeeshan|2> you make too many assumptions
[15:59:27] <CaptHindsight> renesis: it's Sunday, anything goes
[15:59:33] <zeeshan|2> just like you made the assumption of it drawing half the current
[15:59:35] <zeeshan|2> which it clearly isnt
[15:59:41] <renesis> and i told you why
[15:59:43] <zeeshan|2> this isn't a DC motor
[15:59:51] <renesis> its going slower, so the coils are drawing more, so its a wash
[16:00:06] <zeeshan|2> and i don't like your stabs
[16:00:07] <zeeshan|2> like
[16:00:11] <zeeshan|2> "i dont like ac like your mom"
[16:00:13] <zeeshan|2> you're on ignore now
[16:00:19] <renesis> <3
[16:00:25] <CaptHindsight> ok, going to go do something more fun like belt sand my nipples, bbl
[16:00:51] <renesis> do you do summersalts while doing it to get an even chamger on them?
[16:01:20] <zeeshan|2> http://i.imgur.com/PSaJyLu.gif
[16:01:21] <zeeshan|2> hahah
[16:01:27] <zeeshan|2> CaptHindsight: see that before you go
[16:01:30] <zeeshan|2> you'll like it :)
[16:04:12] <renesis> 01:31:01 < renesis> these might do the same thing
[16:04:34] <renesis> see i qualified my assumptions
[16:05:11] <renesis> and what actually happen in real life is in between the two cases
[16:11:13] <Deejay> gn8
[17:40:15] <renesis> http://formulafreak.kinja.com/craig-scarborough-explains-the-mercedes-2014-power-unit-1656299441
[17:41:09] <renesis> they split the exhaust half and the compressor half of the turbo, front and back of engine
[17:41:29] <renesis> with the motor for spool up and energy recover in the middle, in the engine v
[18:52:42] <zeeshan|2> its the wire coming from the tank
[18:52:45] <zeeshan|2> yellow covering
[18:53:38] <pcw_home> level float?
[18:55:15] <zeeshan|2> whats the thing with what it looks like is 2 diodes
[18:55:17] <zeeshan|2> 1 2 3 4
[18:55:40] <zeeshan|2> i thought this central lubrication had just power wires
[18:55:45] <zeeshan|2> but it looks like theres 6 wires coming out of the unit
[18:55:47] <zeeshan|2> no idea where they go :P
[18:56:42] <zeeshan|2> nm
[18:56:46] <zeeshan|2> that this is the"pumpenmotor"
[18:56:47] <zeeshan|2> :P
[18:56:56] <ssi> DAS PUMPENMOTOR
[18:57:00] <pcw_home> thats the pumpenmotor (it has two windings so can be 110V or 220V)
[18:57:02] <zeeshan|2> DAS IS
[18:57:18] <zeeshan|2> okay then the float makes sense
[18:57:28] <zeeshan|2> cause it shuts power off the pump if fluid level is low
[18:57:32] <zeeshan|2> so i guess you dont burn out the motor
[18:57:40] <zeeshan|2> actually
[18:57:42] <zeeshan|2> it could also be a light
[18:57:58] <CaptHindsight> re
[18:58:03] <syyl_> sl1 is a lamp
[18:58:19] <syyl_> "pumpenmotor" is a motor
[18:58:22] <zeeshan|2> das lamp
[18:58:30] <zeeshan|2> is dk and ws
[18:58:34] <zeeshan|2> some sort of timed siwtched
[18:58:37] <zeeshan|2> they have funny arrows on em
[18:59:24] <pcw_home> so lamp is on when pump is running
[18:59:30] <CaptHindsight> zeeshan|2: that gif is with German robots and Japanese swords
[18:59:30] <zeeshan|2> yes
[18:59:37] <zeeshan|2> CaptHindsight: haha
[18:59:48] <zeeshan|2> i looked through my pi&d handbook
[18:59:54] <zeeshan|2> and i couldnt match any of those symbols theyre using
[18:59:58] <zeeshan|2> except the ds
[19:00:03] <zeeshan|2> it looks very similar to a pressure switch
[19:00:15] <CaptHindsight> I dob't think that a Japanese robot vendor would have allowed that :)
[19:00:59] <zeeshan|2> if you think about it
[19:01:00] <pcw_home> Yeah DS could be a pressure switch also
[19:01:07] <zeeshan|2> this machine was made in the era where the berlin wall was still up
[19:01:17] <zeeshan|2> :D
[19:03:23] <pcw_home> which wires went to the controller?
[19:03:46] <zeeshan|2> pcw_home: all i know is thers are 6 wires
[19:03:48] <zeeshan|2> 1 of them is ground
[19:03:52] <zeeshan|2> 2 of them are l1 and l2
[19:03:55] <zeeshan|2> the other 3 are a mystery
[19:04:33] <pcw_home> what pins do the 3 mystery wires go to?
[19:04:43] <zeeshan|2> its really hard to tell
[19:04:45] <zeeshan|2> cause the wiring is am ess in there
[19:04:49] <zeeshan|2> im gonna check
[19:05:01] <syyl_> die lampei would guess that at least one goes to the plc
[19:05:09] <syyl_> -die lampei
[19:05:41] <pcw_home> and which pins are L1 and L2
[19:06:10] <pcw_home> 5 looks like one of L1,L2
[19:06:46] <syyl_> 5 and 8?
[19:07:03] <syyl_> maybe
[19:07:23] <syyl_> happy guessing, i go for my bed ;)
[19:08:03] <pcw_home> not 8 I dont think (motor would be on all the time)
[19:09:53] <pcw_home> also 1,2,3 seem to be be low voltage (UMAX=42V)
[19:12:39] <pcw_home> so my guess is 4,5 = L1,L2
[19:12:41] <pcw_home> 2= sensor switch common
[19:12:42] <pcw_home> 1,3 sensor switch outputs
[19:15:43] <zeeshan|2> dk is a manual switch
[19:15:44] <zeeshan|2> i found it
[19:16:15] <zeeshan|2> okay the wires that went to the external control cabinet are at pin 1, 2, 4, 5, 8, and ground
[19:16:44] <zeeshan|2> and 8 is one leg
[19:16:55] <zeeshan|2> 5 is the other leg
[19:17:44] <zeeshan|2> so the mystery wires are 1 2 4
[19:19:00] <zeeshan|2> i think im wrong about pin 5

[19:22:28] <PetefromTn_> Evening folks.
[19:24:59] <ssi> PetefromTn_: hey
[19:25:01] <ssi> any opinion on this?
[19:25:02] <ssi> http://atlanta.craigslist.org/atl/tls/4735122273.html
[19:26:33] <PetefromTn_> Looks like a big heavy bastard huh
[19:26:35] <zeeshan|2> for cnc?
[19:26:59] <ssi> nah, probably leave it manual
[19:27:00] <PetefromTn_> There is a guy local here that has two machines that look almost exactly like that
[19:27:00] <XXCoder> nicely foggy pics
[19:27:11] <PetefromTn_> yeah that would not be a candidate for CNC really.
[19:27:18] <zeeshan|2> why not
[19:27:33] <ssi> cause it's probably a nice manual lathe
[19:27:36] <ssi> and I need one of those :)
[19:27:38] <PetefromTn_> yeah basically
[19:27:42] <ssi> and I already have two cnc lathes
[19:27:45] <zeeshan|2> whats the diff between cnc lathe
[19:27:46] <zeeshan|2> and manual
[19:27:48] <PetefromTn_> it has all gear driven actions and whatnot
[19:27:53] <ssi> well look at pete's lathe for instance
[19:28:02] <ssi> it doesn't have all the change gears and leadscrew and everything
[19:28:06] <ssi> it's just a bed
[19:28:07] <XXCoder> one has "CNC" in place of "Manual". ;)
[19:28:08] <zeeshan|2> mine did
[19:28:09] <ssi> perfect for cnc
[19:28:12] <PetefromTn_> I mean you could CNC about anything
[19:28:12] <zeeshan|2> it had quick gear change box
[19:28:13] <zeeshan|2> power feed
[19:28:14] <zeeshan|2> etc
[19:28:16] <ssi> sure
[19:28:16] <zeeshan|2> i ripped it all off
[19:28:17] <zeeshan|2> =D
[19:28:24] <zeeshan|2> and just use a button to manually machine
[19:28:27] <PetefromTn_> but it would be a waste to make that one CNC
[19:28:33] <ssi> point is, I'm not gonna take a 70 year old nice manual lathe and throw all the manualy bits away
[19:28:47] <ssi> I'd rather use a grizzly if I were gonna do that
[19:28:47] <XXCoder> isnt there way to do both
[19:28:56] <ssi> and I've already done that :P
[19:28:57] <PetefromTn_> Hey man
[19:28:58] <zeeshan|2> XXCoder: yea its called handwheels w/ encoders
[19:28:59] <zeeshan|2> :P
[19:29:08] <PetefromTn_> I just spent most of the day underneath my house
[19:29:18] <XXCoder> sounds fun. buring bodies.
[19:29:34] <PetefromTn_> I would like to kick the ass of the guy who did the air conditioning install
[19:29:39] <zeeshan|2> ssi what lathes do you have
[19:29:39] <ssi> I spent all night last night cleaning up stuff
[19:29:42] <zeeshan|2> other than hnc
[19:29:43] <ssi> I cleaned up my tube amps and stuff
[19:29:47] <ssi> zeeshan|2: G0602
[19:29:57] <PetefromTn_> I basically removed half the return plenum
[19:29:57] <ssi> I had a clausing 6300 12x36 but I sold it to Dannifer
[19:30:10] <ssi> I cleaned up one of my basses that was hanging on the wall and real bad off
[19:30:11] <ssi> https://fbcdn-sphotos-e-a.akamaihd.net/hphotos-ak-xap1/v/t1.0-9/10425496_10100519846900152_6080753954434852054_n.jpg?oh=de246030f010a7f33d250926c92c131a&oe=551B63FD&__gda__=1424577704_9cb98d21e1632d20f3d43263c64f4333
[19:30:16] <zeeshan|2> whats the point of having 3 lathes
[19:30:17] <zeeshan|2> :D
[19:30:23] <ssi> after a lot of scrubbing and wax
[19:30:23] <ssi> https://scontent-a-lga.xx.fbcdn.net/hphotos-xfa1/v/t1.0-9/10703622_10100519876460912_1395401883298200434_n.jpg?oh=e0f818e5372e78c991fd741076d6ed8f&oe=54E8DA30
[19:30:28] <zeeshan|2> wow
[19:30:28] <PetefromTn_> nice
[19:30:33] <zeeshan|2> ssi to be honest with you
[19:30:37] <zeeshan|2> that looked cooled smoked
[19:30:37] <zeeshan|2> lol
[19:30:39] <zeeshan|2> *cool
[19:30:41] <PetefromTn_> are any of you guys good with sheetmetal?
[19:30:51] <ssi> I built an airplane from scratch :P
[19:30:52] <XXCoder> heh careful there is things that lose value with cleaning
[19:31:02] <PetefromTn_> well I have a serious question for yo.
[19:31:04] <PetefromTn_> you
[19:31:19] <ssi> my sheetmetal skills are not exactly the same as HVAC sheetmetal skills tho :P
[19:31:25] <PetefromTn_> basically all the duct work under my house is mostly rectangular
[19:31:55] <PetefromTn_> and the new unit has those square to round adapters so you can run the more efficient 14" round insulated ducting
[19:32:20] <PetefromTn_> so after removing all the laughable leaky, shitty plemun they built under there
[19:32:33] <PetefromTn_> I now have two rectangular duct openings
[19:32:37] <PetefromTn_> one for supply
[19:32:39] <PetefromTn_> one for return
[19:33:03] <PetefromTn_> I have to adapt both of them to the new unit which has two 14" round pieces of duct going into it.
[19:33:17] <PetefromTn_> I saw a couple videos on youtube about how to do that
[19:33:30] <PetefromTn_> but they used some fancy software
[19:33:41] <PetefromTn_> to figure the angles and bend locations
[19:34:12] <PetefromTn_> I was wondering if any of you guys know how to do this so I can get it designed and maybe get a .dxf of it and transfer the dims to real sheetmetal here
[19:35:00] <PetefromTn_> I got the rest of it sorted out and we will be installing the new unit this week.
[19:36:14] <PetefromTn_> https://www.youtube.com/watch?v=pxhHBgPYdrM something like this
[19:36:34] <zeeshan|2> you can do that in inventor
[19:36:35] <zeeshan|2> or solidworks
[19:36:37] <PetefromTn_> https://www.youtube.com/watch?v=bYs4_STaQlU
[19:36:39] <zeeshan|2> using sheet metal module
[19:36:44] <PetefromTn_> that is a video showing the software
[19:37:32] <PetefromTn_> Basically what I need is that kind of transition only it has to be offset to the top or bottom. IE the round part is not in the middle of the rectangular part.
[19:37:47] <zeeshan|2> do you wanna do it with 2 sheet metal pieces
[19:37:48] <zeeshan|2> that you weld together
[19:37:50] <zeeshan|2> or 1 piece
[19:38:03] <PetefromTn_> probably two I will just rivet it together
[19:38:11] <zeeshan|2> do you know the dimensions
[19:38:14] <PetefromTn_> sure
[19:38:23] <PetefromTn_> the round is as said 14" diameter
[19:38:41] <PetefromTn_> the two rectangular plenums are 10x18 and 10x20
[19:39:08] <zeeshan|2> let me clarify
[19:39:09] <PetefromTn_> I started to draw it in freecad but I do not know how to unfold it once it is done
[19:39:20] <zeeshan|2> you need sheet metal module to do that
[19:39:24] <zeeshan|2> does freecad have it?
[19:39:28] <PetefromTn_> doubt it
[19:39:32] <zeeshan|2> are you doing 14" round ->? 10x18 for one
[19:39:37] <zeeshan|2> and anotehr is 14" round -> 10x20?
[19:39:42] <PetefromTn_> yeah
[19:39:47] <zeeshan|2> length of transition?
[19:39:58] <PetefromTn_> whatever makes the most sense..
[19:40:02] <zeeshan|2> haha
[19:40:07] <PetefromTn_> I am not limited by the distance
[19:40:25] <PetefromTn_> they are both pointing towards the unit which is like ten feet awar
[19:40:27] <PetefromTn_> away
[19:40:33] <PetefromTn_> say 24" or so?
[19:40:53] <PetefromTn_> less if possible to get the most efficient use of materials
[19:40:58] <PetefromTn_> and easiest bends.
[19:41:09] <PetefromTn_> This shit is thin so that is not really a problem.
[19:41:24] <PetefromTn_> do you have sheetmetal module?
[19:41:27] <zeeshan|2> what is material thickness
[19:41:27] <zeeshan|2> yea
[19:41:38] <PetefromTn_> hang on I will measure it.
[19:42:58] <PetefromTn_> Looks like about .023"
[19:43:57] <PetefromTn_> probably 24 gauge
[19:45:15] <PetefromTn_> You can see in that video they made some like 1" flanges in the ends of the rectangular part.
[19:45:26] <PetefromTn_> That would make it much easier to attach it
[19:46:13] <PetefromTn_> I am gonna call this AC shop down the hill from me in the morning to see what they might charge to make them but I have a BUNCH of sheetmetal here from the old plenum shit I removed that I can probably use to make my own.
[19:48:34] <PetefromTn_> ssi You gonna buy that lathe?
[19:51:16] <zeeshan|2> pete
[19:51:19] <zeeshan|2> i have it made
[19:51:28] <zeeshan|2> but the thing is i dont get where you want the flanges
[19:51:29] <zeeshan|2> on the rect part
[19:51:57] <PetefromTn_> well the first thing is like I said it needs to be oriented offset to one side of the rectangular part.
[19:51:58] <zeeshan|2> lemme show you apic
[19:52:21] <PetefromTn_> In other words the edge of the round has to be parallel to one of the long edges of the rectangle
[19:52:32] <PetefromTn_> BTW thanks for doing that
[19:52:37] <PetefromTn_> I appreciate it
[19:52:59] <zeeshan|2> np
[19:53:00] <zeeshan|2> i hope this is what u need
[19:53:14] <zeeshan|2> http://i.imgur.com/so7ATzD.png
[19:53:19] <zeeshan|2> is that the shape?
[19:53:58] <zeeshan|2> oh
[19:53:58] <zeeshan|2> shit
[19:54:16] <PetefromTn_> yup I think so but it is hard to tell if the round part edge is inline with one of the square edges
[19:54:50] <zeeshan|2> can you tell me the video
[19:54:53] <PetefromTn_> basically the round part has to be offset the four inches from the long edge across from it on one side.
[19:54:54] <zeeshan|2> and wart part
[19:55:04] <PetefromTn_> hang on.
[19:55:09] <zeeshan|2> *what
[19:57:56] <PetefromTn_> https://www.youtube.com/watch?v=bYs4_STaQlU In this video at .26 you can see a small picture of the duct preview in the top left of the screen. YOu can see how the round hole is offset from the center and from the side
[19:58:17] <zeeshan|2> yes
[19:58:29] <PetefromTn_> Basically I need the round hole in the center of the long axis and offset to the top or bottom in the short side 10" dimension.
[19:58:29] <zeeshan|2> how much of an offset do you need
[19:58:57] <PetefromTn_> whatever puts the round hole even with the long side 18" or 20" depending on which one you are drawing first
[19:59:06] <zeeshan|2> ok lemme show you an image
[19:59:10] <zeeshan|2> thatll clarify it a bit better
[19:59:14] <PetefromTn_> trying to find you a picture to represent
[19:59:46] <PetefromTn_> at 1:53 in that video you see the side view that is exactly what I need
[20:00:10] <zeeshan|2> okayt you want it shifted to the right
[20:00:20] <zeeshan|2> is it okay if its like 1" away
[20:00:21] <zeeshan|2> from the corner?
[20:00:34] <PetefromTn_> yeah I need it 90 degrees on one side that is the long side.
[20:00:42] <PetefromTn_> but centered on the long edge
[20:01:43] <PetefromTn_> hard to describe I guess
[20:01:53] <PetefromTn_> if you look at it from the round hole side
[20:02:08] <PetefromTn_> the edge of the round hole will be even with the middle of one of the long edges
[20:02:29] <PetefromTn_> and the round hole will be centered along the length of the long edge from side to side
[20:03:45] <zeeshan|2> http://i.imgur.com/tka24Ir.png
[20:03:48] <zeeshan|2> kinda like that?
[20:05:10] <PetefromTn_> unfortunately not really the rectangular part would need to be centered on the round part....and the top edge of the round part would touch the top edge of the rectangular part
[20:05:51] <zeeshan|2> hm
[20:06:07] <zeeshan|2> but the diameter is 14"
[20:06:10] <PetefromTn_> so the bottom half you did not show would be a larger piece due to the offset
[20:06:12] <zeeshan|2> and the rect part is 10"
[20:06:16] <PetefromTn_> yeah
[20:06:50] <zeeshan|2> might be easier to do it with just one piece then :P
[20:07:14] <PetefromTn_> basically just like in that video I just posted but the round part needs to be in the middle of the long direction
[20:07:43] <zeeshan|2> yea but its bit eaasier for him
[20:07:49] <zeeshan|2> cause the tube is smaller than the rect
[20:08:10] <PetefromTn_> yeah I know
[20:08:25] <zeeshan|2> what makes it challenging is
[20:08:28] <zeeshan|2> one part is expanding
[20:08:32] <zeeshan|2> while another part is collapsiing
[20:08:34] <zeeshan|2> if you kow what i mean
[20:08:49] <PetefromTn_> ssi http://knoxville.craigslist.org/tls/4721684300.html looks like a nice machine here too..
[20:09:08] <PetefromTn_> yeah I know that is why I was hoping to get a cad drawing done.
[20:09:18] <PetefromTn_> I thought about using cardboard to try to build it
[20:09:24] <PetefromTn_> then transfer it to sheetmetal
[20:10:06] <PetefromTn_> Lemme work on a 3d model of what I need and maybe I can just send you that and you can use it easier?
[20:14:30] <zeeshan|2> sounds good
[20:15:30] <zeeshan|2> can you check this out
[20:15:52] <zeeshan|2> http://i.imgur.com/ORekOqL.png
[20:15:54] <zeeshan|2> like that i hope?!?!
[20:16:09] <zeeshan|2> or does the top of the circle
[20:16:14] <zeeshan|2> have to be exactly tangent
[20:16:18] <zeeshan|2> to the rect line
[20:16:49] <zeeshan|2> nm
[20:16:55] <zeeshan|2> i changed it to tangent
[20:16:57] <zeeshan|2> and it works
[20:17:22] <PetefromTn_> yeah if the rectangle was touching the top of the circle it would be what I need
[20:17:37] <PetefromTn_> working on the drawing right now but that is basically it.
[20:17:54] <PetefromTn_> The bottom half if split on the 10" side would be larger than the top halp
[20:17:55] <PetefromTn_> half
[20:18:23] <zeeshan|2> http://i.imgur.com/573wYKk.png
[20:18:33] <PetefromTn_> it's basically a loft op
[20:18:44] <zeeshan|2> yes
[20:19:40] <PetefromTn_> yeah that last one is it. as long as the square dimensions are 10x18 or 10x20 and the round is 14"
[20:20:36] <zeeshan|2> its not liking it
[20:20:40] <zeeshan|2> not wanting to flat pattern
[20:20:56] <PetefromTn_> hm
[20:21:13] <PetefromTn_> as long as it is close to level with the top edge it should be fine.
[20:21:48] <zeeshan|2> ok it worked
[20:21:49] <zeeshan|2> it was my fault
[20:21:50] <zeeshan|2> lol
[20:21:50] <PetefromTn_> The duct is strapped to the bottom of the floor joists suspended a few inches underneath it so if it was just centered it would not be able to be installed because the top edge would hit the joists
[20:23:14] <zeeshan|2> im just confirming if the flat pattern makes sense
[20:23:29] <PetefromTn_> no hurry here LOL
[20:24:04] <zeeshan|2> yea the flat pattern makes no sense
[20:24:05] <zeeshan|2> haha
[20:27:07] <zeeshan|2> there we go!
[20:27:10] <zeeshan|2> how many b end lines do you want
[20:27:12] <zeeshan|2> for the curve
[20:27:24] <PetefromTn_> as few as possible to make it work right
[20:27:38] <PetefromTn_> I don't have a brake here so I will be doing it the hard way
[20:27:39] <zeeshan|2> well think of it like this
[20:27:46] <zeeshan|2> you got a circle
[20:27:55] <zeeshan|2> if you do 8 bend lines total
[20:27:59] <zeeshan|2> you have 8 flat portions on that curve
[20:28:00] <PetefromTn_> http://i.imgur.com/jR4dTiy.jpg
[20:28:21] <PetefromTn_> yeah I understand the concept
[20:28:28] <zeeshan|2> so you gotta make the call
[20:28:31] <PetefromTn_> probaly like ten or so five from each side
[20:28:42] <zeeshan|2> okay make a 10 sided polygon in freecad
[20:28:46] <zeeshan|2> and see if it looks okay to you
[20:28:46] <zeeshan|2> :D
[20:28:54] <PetefromTn_> should allow me to get it done and not be bending for days
[20:28:59] <zeeshan|2> haha
[20:29:04] <PetefromTn_> no I know what it will look like;
[20:29:19] <PetefromTn_> I just don't have the software to make it unfold
[20:29:32] <PetefromTn_> so I can use the .dxf to create the real thing here in the shop
[20:30:08] <zeeshan|2> http://i.imgur.com/LwpSqNO.png
[20:30:10] <PetefromTn_> you see I bought a couple 14" round adapter rings that have sheetmetal fingers all the way around for riveting or screwing it in
[20:30:12] <zeeshan|2> does that look ok?
[20:30:28] <zeeshan|2> looks like a nightmare to me :D
[20:30:51] <PetefromTn_> looks like twelve which should be fine actually
[20:30:54] <ssi> PetefromTn_: that clausing does look nice, although it's hard to tell with atht one blurry picture
[20:30:57] <Connor> ssi murphy oil soap works good on smoked covered stuff.. I know from exp.
[20:31:04] <zeeshan|2> PetefromTn_: its gotta be a multiple of 4
[20:31:09] <ssi> yeah
[20:31:11] <PetefromTn_> okay that is fine
[20:31:13] <zeeshan|2> for each quadrant of the circle
[20:31:21] <zeeshan|2> okay thats the 10x18
[20:31:35] <zeeshan|2> lemme send you the DXF
[20:31:43] <PetefromTn_> ok
[20:31:59] <PetefromTn_> so that is half right which half is it?
[20:32:10] <zeeshan|2> no thats the whole thing
[20:32:24] <PetefromTn_> oh sorry you are right
[20:32:33] <zeeshan|2> all you gotta do is rivet it
[20:32:34] <zeeshan|2> at the end
[20:32:46] <PetefromTn_> yeah
[20:32:52] <PetefromTn_> I can split it If I need to
[20:32:56] <zeeshan|2> yes
[20:33:01] <PetefromTn_> wish I had a bigass plotter here LOL
[20:33:05] <zeeshan|2> yea man
[20:33:08] <ssi> I have a bigass plotter :P
[20:33:09] <zeeshan|2> you could print it out
[20:33:12] <zeeshan|2> and test it on a piece of paper first
[20:33:12] <zeeshan|2> haha
[20:33:13] <ssi> I need ink cartridges for it
[20:33:28] <PetefromTn_> that would be easiest
[20:33:35] <PetefromTn_> but I will have to do it the hard way
[20:33:48] <PetefromTn_> laying it all out on the metal from dims from the .dxf
[20:33:56] <PetefromTn_> what does the solid model look like>
[20:34:51] <zeeshan|2> http://i.imgur.com/vAQtdJn.png
[20:34:56] <zeeshan|2> theres an extra line theere
[20:34:59] <zeeshan|2> cause its the split line
[20:35:19] <PetefromTn_> that looks beatiful man
[20:35:22] <zeeshan|2> this is one of those drawings
[20:35:24] <PetefromTn_> exactly what I need
[20:35:30] <zeeshan|2> that you hope to god you'll never have to draw in drafting class
[20:35:31] <zeeshan|2> by hand
[20:35:32] <PetefromTn_> thank you
[20:35:34] <zeeshan|2> np man
[20:35:38] <zeeshan|2> 10x18
[20:35:41] <zeeshan|2> what was the other one
[20:35:45] <PetefromTn_> 10x20
[20:35:53] <PetefromTn_> exactly the same orientation
[20:35:56] <zeeshan|2> okay
[20:36:24] <PetefromTn_> it's too bad ssi is so far away I could have him burn it for me on the plasma and then I would just need to bend the friggin thing
[20:37:19] <ssi> if my plasma was set up :P
[20:37:33] <ssi> the water table is actually out at the coaters getting blasted and powder coated
[20:37:41] <zeeshan|2> i forget
[20:37:44] <zeeshan|2> if i save it as dxf
[20:37:46] <zeeshan|2> and im using 1:8 scale
[20:37:49] <zeeshan|2> will it show up on your end?
[20:38:19] <zeeshan|2> im gonna leave one dimension in there
[20:38:23] <zeeshan|2> it should say 17.5"
[20:38:25] <zeeshan|2> and measure it
[20:38:30] <zeeshan|2> just double check
[20:38:56] <PetefromTn_> you can't save it 1-1?
[20:39:20] <PetefromTn_> I can just scale it here in .dxf form I guess
[20:39:29] <zeeshan|2> i wouldnt want you scaling it on your end
[20:39:35] <zeeshan|2> ive had some bad experience with tha tbefore
[20:39:41] <PetefromTn_> ?
[20:39:43] <zeeshan|2> if that one line measures 17.5"
[20:39:52] <zeeshan|2> we're good!
[20:40:10] <PetefromTn_> what was the total length you wound up using?
[20:40:23] <zeeshan|2> 24
[20:40:29] <PetefromTn_> okay
[20:41:06] <zeeshan|2> should i email these
[20:41:12] <PetefromTn_> sure
[20:42:27] <PetefromTn_> this will be much more efficient and smoother than just adding a freakin' box like the other guys did. More work but I think it will be worth it.
[20:42:52] <PetefromTn_> I will just add the flanges of like 1.5" to the rectangular end before I try to cut it out.
[20:43:09] <PetefromTn_> Probably cut it from cardboard first to make sure it will work.
[20:43:25] <PetefromTn_> ssi that is a nice looking clausing tho huh?
[20:43:38] <PetefromTn_> If I had 3k laying around I would go look at it I think,
[20:43:50] <PetefromTn_> probably get it for $2500
[20:49:03] <zeeshan|2> yea id definitely do it with cardboard first
[20:49:06] <zeeshan|2> i was making this:
[20:50:07] <zeeshan|2> http://i130.photobucket.com/albums/p252/turbozee84/sheetmetal_zps667cac4d.png
[20:50:10] <zeeshan|2> for an intercooler pipe
[20:50:12] <zeeshan|2> weird ass transition
[20:50:19] <zeeshan|2> i printed that out
[20:50:23] <zeeshan|2> and layed it on the pipe and traced it
[20:50:41] <zeeshan|2> it still needd like about 1/16-1/8" of clean up
[20:50:41] <PetefromTn_> yeah it would be nice to have those capabilities
[20:50:44] <zeeshan|2> to get a perfect fit
[20:50:53] <PetefromTn_> I usually just cave man it
[20:51:09] <zeeshan|2> i used to too to be honest
[20:51:21] <zeeshan|2> but after i wasted some stainless tubing
[20:51:26] <zeeshan|2> i was like f it!
[20:51:28] <PetefromTn_> but for something like this I wanted to try to make sure I got it right since it is going to ensure my house is energy efficient
[20:52:18] <PetefromTn_> I also only have a certain amount of sheetmetal here to play with so screwing one up would make me have to reach into my poscket some more
[20:52:38] <zeeshan|2> http://i130.photobucket.com/albums/p252/turbozee84/ypipe_zps6992c98a.png
[20:52:41] <zeeshan|2> this was another weird one
[20:52:47] <zeeshan|2> trying to figure out how to cut the transition right
[20:53:20] <zeeshan|2> i ended up cave manning that one
[20:54:26] <zeeshan|2> i sent the dxfs
[20:54:31] <zeeshan|2> plz lemme know if they open right
[20:54:35] <zeeshan|2> one dimension should be 17.5
[20:54:40] <zeeshan|2> the other should be 19.5 (for the 10x20)
[20:54:49] <PetefromTn_> look good so far.
[20:54:51] <PetefromTn_> BRB
[20:54:56] <PetefromTn_> Gotta put my kids to bed
[21:12:08] <PetefromTn_> well the 17.5" dimension shows the same in my program so it's all good.
[21:15:41] <PetefromTn_> neato
[21:16:00] <PetefromTn_> the bend angles actually already have the dimension angles listed
[21:41:15] <ssi> bleh
[21:41:24] <ssi> I need to weld something, but the welder's not set up and I don't know where to put it
[21:41:28] <ssi> and I need to run 220 for it
[21:41:35] <PetefromTn_> bring it up here man LOL
[21:41:42] <ssi> yeah that sounds ealier :P
[21:41:45] <ssi> easier
[21:43:52] <zeeshan|2> PetefromTn_
[21:43:56] <zeeshan|2> you have a box and pan brake?
[21:44:03] <PetefromTn_> nope LOL
[21:44:08] <zeeshan|2> they confuse me
[21:44:13] <zeeshan|2> theres so many different kinds
[21:44:16] <zeeshan|2> i never know which one to buy
[21:44:18] <Connor> I want a 24" one..
[21:44:32] <ssi> we have a 48" enco box brake here
[21:44:33] <ssi> but it mostly sucks
[21:44:50] <zeeshan|2> whats the biggest length of the box
[21:44:52] <zeeshan|2> you can maake
[21:44:54] <zeeshan|2> length = depth
[21:45:04] <ssi> I dunno
[21:45:08] <zeeshan|2> the ones were at eaton were quite different
[21:45:09] <Connor> http://www.grizzly.com/products/24-Box-and-Pan-Brake/G0557
[21:45:13] <zeeshan|2> i dont think theyre called box and pan brakes
[21:45:14] <Connor> that's the one I want.
[21:45:33] <zeeshan|2> http://www.jps-machinery.co.uk/wp-content/uploads/2013/03/Hydraulic-press-brake-2.jpg
[21:45:34] <zeeshan|2> it was like that
[21:45:35] <Connor> G0557 24" Box and Pan Brake
[21:45:43] <zeeshan|2> is that still considered a "box and pan brake"
[21:45:44] <zeeshan|2> lol
[21:45:51] <zeeshan|2> i just called it a "brake press"
[21:45:52] <PetefromTn_> they make a large combo machine I would not mind having but they will not genereally do anything real thick
[21:46:04] <ssi> I would try to find the one we have on the enco site
[21:46:05] <Connor> If it has fingers that can be removed.. then yes.. it's a box and pan brake
[21:46:05] <ssi> but it blows
[21:46:13] <ssi> unknown word
[21:46:14] <ssi> We were unable to find an exact match for your search for "BRAKE"
[21:46:18] <zeeshan|2> yea you can remove the fingers
[21:46:20] <zeeshan|2> and adjust them
[21:46:23] <zeeshan|2> and put different types of dies
[21:46:41] <PetefromTn_> I would rather have a nice big press brake
[21:46:44] <zeeshan|2> like i never understood why these things needed to be so huge
[21:46:49] <zeeshan|2> like it looks like it weighs 15,000 lb
[21:46:50] <zeeshan|2> or more
[21:46:56] <Connor> PetefromTn_: 48" ?
[21:46:57] <zeeshan|2> yet a box and pan brake 48" is like..
[21:46:59] <zeeshan|2> 1000 lb
[21:47:20] <ssi> ours is way less than that even
[21:47:22] <Connor> zeeshan|2: Thickness of material you can bend dictates it's mass
[21:47:23] <ssi> maybe 500lb
[21:47:26] <zeeshan|2> connor
[21:47:32] <zeeshan|2> these things did like .185" max
[21:47:34] <zeeshan|2> or .2"
[21:47:42] <zeeshan|2> that doesnt seem like a lot
[21:47:52] <ssi> it doesn't?
[21:47:53] <ssi> heh
[21:48:00] <PetefromTn_> http://img.directindustry.com/images_di/photo-g/hydraulic-presses-brake-cnc-113373-5558131.jpg
[21:48:08] <zeeshan|2> no it doesnt
[21:48:11] <zeeshan|2> when you consider hydraulics
[21:48:25] <Connor> STEEL ?
[21:48:25] <zeeshan|2> yes something like ete posted
[21:48:35] <zeeshan|2> is what i imaged something that can easily do .2" steel
[21:48:35] <Connor> That's damn thick to be bending.
[21:48:35] <zeeshan|2> no prob
[21:48:40] <roycroft> that's quite a bit when you're talking about a sheet metal brake
[21:48:50] <PetefromTn_> http://www.bangshift.com/assets/images/news/2009/May/10-16/press%20brake.jpg
[21:48:53] <roycroft> and when you're talking 1000lbs you're talking about a sheet metal brake
[21:49:00] <ssi> it's one thing to bend a piece of 1/4" steel thats's 2-3" wide
[21:49:07] <ssi> it's another hting entirely to bend 48" of 1/4" steel
[21:49:18] <zeeshan|2> i know!
[21:49:23] <zeeshan|2> i calculated the forces before
[21:49:56] <Connor> Anywho... the little 24" would suit my needs.. just not sure where I would put it.
[21:50:03] <zeeshan|2> maybe its something to do with distortion
[21:50:04] <zeeshan|2> and not forces
[21:50:24] <zeeshan|2> like yea the metal might not yield at 50 ton force
[21:50:34] <zeeshan|2> (the frame of the brake press)
[21:50:36] <zeeshan|2> but it might flex
[21:51:22] <roycroft> i had to bend some 0.120" 304 ss a couple weeks ago
[21:51:27] <roycroft> the pieces were about 2" wide
[21:52:03] <roycroft> i milled a vee groove in the pieces at the bend point 0.060" deep
[21:52:29] <roycroft> my 30" 3 in one sheet metal machine just about broke trying to do the bend
[21:53:03] <roycroft> it's rated to bend 20ga ss at full width
[21:58:23] <PetefromTn_> Working on a little birthday present for my wife
[21:59:08] <PetefromTn_> She's a huge fan...
[21:59:24] <PetefromTn_> http://i.imgur.com/aDsNHlF.jpg
[22:03:24] <PetefromTn_> Thinking I will engrave it into some plexiglass or something and then make a base out of wood and backlight it with some change color LED's somehow.
[22:05:18] <PetefromTn_> https://www.youtube.com/watch?v=uIO6WB_fWNc
[22:07:28] <PetefromTn_> says they used a 5050 LED strip whatever that is.
[22:08:57] <PetefromTn_> http://www.ebay.com/itm/New-5M-5050-RGB-SMD-Waterproof-Flexible-led-Strip-300-LEDs-24-Key-IR-Remote-/170922603127?pt=US_Car_Lighting&hash=item27cbc7f277 Pretty cheap!
[22:11:50] <zeeshan|2> yo ssi
[22:11:56] <zeeshan|2> is there anyway to interface the brake for z axis
[22:11:58] <zeeshan|2> with amc drives?
[22:14:22] <ssi> not those drives
[22:14:30] <ssi> just have the same enable drive a relay
[22:14:47] <ssi> https://scontent-a-ord.xx.fbcdn.net/hphotos-xap1/v/t1.0-9/9766_10100520524791652_4657380844245345821_n.jpg?oh=c70992eaa2662bc8482777750adb367a&oe=54E650DD
[22:15:30] <zeeshan|2> my enable signal comes right from mr 7i77
[22:15:37] <ssi> sure
[22:15:39] <zeeshan|2> and i think its limited to 300mA
[22:15:46] <zeeshan|2> so youre saying throw a relay in between
[22:16:10] <zeeshan|2> a 1-2 s delayed relay that is
[22:16:14] <zeeshan|2> (like pete was talking about)
[22:16:22] <ssi> I dunno that I'd delay it that long
[22:16:40] <zeeshan|2> i mean delay the enable
[22:16:42] <zeeshan|2> by 1-2 sec
[22:16:47] <zeeshan|2> wait wtf am i saying
[22:17:05] <zeeshan|2> i want the brake to enable for a small duration
[22:17:17] <zeeshan|2> till axis is enabled
[22:17:21] <PetefromTn_> You probably need to look into having linuxCNC output another signal to enable the relay a second or two BEFORE the enable signal goes off
[22:17:29] <ssi> that's easy
[22:17:32] <ssi> well
[22:17:41] <ssi> before isn't easy
[22:17:43] <zeeshan|2> PetefromTn_: is that how youre doing it on the cinci?
[22:17:47] <ssi> but honestly I don't think it'd be that big a deal
[22:18:06] <PetefromTn_> no as I said my drives take care of that internally but that is basically how it works
[22:18:17] <zeeshan|2> f it
[22:18:24] <zeeshan|2> disable brake
[22:18:27] <zeeshan|2> at the same time enabling drive
[22:18:28] <zeeshan|2> see what happens
[22:18:30] <zeeshan|2> :-)
[22:18:39] <ssi> they can't know that you're disabling them before you disable them
[22:18:46] <PetefromTn_> mine would drop about a quarter inch or so.
[22:18:47] <zeeshan|2> ssi well
[22:18:50] <zeeshan|2> asap it gets an enable signal
[22:18:53] <PetefromTn_> probably more
[22:18:54] <zeeshan|2> you can start a timer
[22:19:02] <zeeshan|2> before the actual enable happens
[22:19:05] <ssi> and I certainly wouldn't want them to keep the drive enabled
[22:19:56] <PetefromTn_> enabling the drives is the easy part it is disabling the drives and applying the brake the causes the drop
[22:20:16] <zeeshan|2> oh
[22:20:23] <zeeshan|2> well remember
[22:20:25] <zeeshan|2> my brake is normally closed
[22:20:28] <zeeshan|2> so its always on
[22:20:30] <PetefromTn_> if they happen simultaneously the head drops a little bit before the brake can engage
[22:21:01] <zeeshan|2> until you press 24vdc through it and i think that disables it
[22:21:09] <zeeshan|2> i have still to test it
[22:21:20] <PetefromTn_> the brake should be engaged whenever power is NOT applied to it.
[22:21:27] <zeeshan|2> PetefromTn_: yes
[22:21:52] <PetefromTn_> when you enable the drive the power is turned on DIS engaging the brake
[22:21:54] <zeeshan|2> ill try it out without any delay
[22:21:58] <zeeshan|2> if its got an issue, ill add a delay
[22:22:06] <PetefromTn_> works for me
[22:22:30] <zeeshan|2> what happens if you dont disable the brake
[22:22:34] <zeeshan|2> and try to run the servo? :D
[22:22:46] <zeeshan|2> is that a good way to blow up your 24vdc power supply
[22:22:47] <PetefromTn_> Like I said my head dropped about a quarter inch before we played with the delay in the drives settings
[22:23:36] <zeeshan|2> that can be pretty dangerous :P
[22:23:39] <PetefromTn_> now when I hit the servo on/off button in linuxCNC there is a little click and you can hear the brake engage and then you can hear the servo depowering a moment later
[22:23:45] <zeeshan|2> especially if your end mill is sitting 1/4" above your work piece!
