[00:03:55] <Tom_L> andypugh, you might find parts of this useful: http://www.knucklebusterinc.com/features/wp-content/2011/09/Sheet_Metal_Fabrication.pdf
[00:04:12] <norias> i'm out folks
[00:04:13] <norias> thanks!

[00:04:23] <Tom_L> P 50 shows rolling a lip
[00:08:25] <andypugh> What is the page number of page 50?
[00:09:19] <malcom2073> 277+50?
[00:10:04] <Tom_L> 326
[00:10:11] <andypugh> Thanks
[00:10:27] <Tom_itx> there's a bit more a few pages ahead of that too
[00:10:34] <Tom_itx> around 40 ish
[00:11:06] -!- The_Ball [The_Ball!~ballen@202.10.92.134] has joined #linuxcnc
[00:11:17] <andypugh> That is beading, I have a beading tool.
[00:11:28] <Tom_L> ok
[00:11:30] <andypugh> The flange is different, and difficult.
[00:11:45] <Tom_L> yeah the metal keeps wanting to walk out on you right?
[00:12:35] <andypugh> Well, as I spin-down the chuch-side of the flange it “unrolls” the tailstock side.
[00:12:47] <andypugh> And how you get a constant diameter I have _no_ idea.
[00:12:53] <robinsz> andypugh, I have a company making stuff for guitarists and pa systems, the router we do prototypes on shat itself after christmas
[00:13:34] -!- moorbo has quit [Ping timeout: 245 seconds]
[00:13:35] <andypugh> That sounds unfortunate.
[00:13:41] <robinsz> indeed.

[00:14:24] -!- BellinganRoy has quit [Quit: Konversation terminated!]
[00:14:31] <robinsz> so ... shoudl I upgrade from EMC2? I just booted the machine ... it was last turned on in August ...
[00:14:39] <robinsz> 2008 ...
[00:14:39] <andypugh> Tom_L: It is perhaps telling that this replica lamp was made with a different style of flange: http://www.geutskens.eu/neracar/images/PPL/8-Accessories/807-Headlamp%20Acetylene/02-807-Headlamp%20Ace-lhv-gec.jpg
[00:15:10] <robinsz> been any bugfixes since 2008? ;)
[00:15:46] <andypugh> robinsz: One or two. But it’s unlikely that the PC will run a version of Linux that will run the latest version.
[00:16:32] <robinsz> what was 2008? hardy heron?
[00:16:32] <Tom_L> https://www.youtube.com/watch?v=3D4t9pp7y-I
[00:16:53] <robinsz> is there a liveboot these days?
[00:16:56] <andypugh> Yes. And I am pretty sure we dropped Hardy support.
[00:17:10] <andypugh> Yes, in the usual place at www.linuxcnc.org
[00:17:14] <robinsz> righty
[00:17:19] <andypugh> But they seem to have switched to Debian Wheezy.
[00:17:26] <robinsz> oh, good call
[00:17:34] <andypugh> (I am happy enuough with Ubuntu.)
[00:17:38] <robinsz> debian is slurpy!
[00:17:49] <Tom_itx> i updated my ubuntu to 2.6
[00:18:04] <Tom_itx> will probably go to 2.7 soon
[00:18:20] <robinsz> andypugh, anyting else happened in the last 7 years since we spoke?
[00:18:40] <andypugh> Not in my life :-)
[00:18:45] <robinsz> same ;)
[00:19:51] <robinsz> I visited Beaver in Swaziland, but thats about it
[00:20:11] <PetefromTn_> Hey folks
[00:20:28] <robinsz> good een
[00:20:43] <PetefromTn_> happy to report that the Cincinatti has been rigid tapping parts for me all afternoon LOL!
[00:20:55] <robinsz> this is "interesting" fsvo "interesting" http://dynomotion.com/KFLOP.html
[00:21:05] <Tom_itx> PetefromTn_, prove it!
[00:21:23] <robinsz> nice, rigid tapping is always fun, you have spindle encoder or tach?
[00:21:24] <PetefromTn_> 3/8-16 half inch deep in 6061..
[00:21:37] <_methods> nice
[00:21:38] <PetefromTn_> aluminum rods in the 5c collet fixture
[00:21:41] <_methods> tappin alum sux
[00:21:42] <PetefromTn_> vertically...
[00:21:43] <mozmck> andypugh: I don't mind Ubuntu, but I don't like the Unity desktop
[00:22:02] <andypugh> I got used to Unity pretty quickly.
[00:22:04] <mozmck> So I switched to LinuxMint - and use Cinnamon and XFCE
[00:22:08] <The_Ball> PetefromTn_, so external threads?
[00:22:15] <mozmck> andypugh: Do you do much with it?
[00:22:24] <andypugh> Not really.
[00:22:29] <witnit> this new distro seems so much lighter
[00:22:32] <witnit> i like it
[00:22:52] <mozmck> andypugh: That's probably the difference then - it's my main/only OS, and I use it for work and everything else.
[00:22:52] <The_Ball> witnit, which one?
[00:23:12] -!- Tom_L has quit []
[00:23:25] <mozmck> I have 5 workspaces, and many programs and virtualbox VMs running on various workspaces at once.
[00:23:31] <witnit> the iso on the the website

[00:24:01] <_methods> xubuntu
[00:24:04] <PetefromTn_> The_Ball No internal..
[00:24:04] <witnit> the last one one i had used was ubuntu
[00:24:09] <PetefromTn_> standby for pics...
[00:24:09] <_methods> plain old xfce FTW
[00:24:11] <andypugh> I find pretty much every App and foile on my Mac with CMD-Space so searching for most things in Unity feels sort-of familiar. I have a feeling that we have too many files and apps now for icons to actually be a sensible paradigm any more.
[00:24:14] <witnit> this is xfce
[00:24:46] <_methods> all the other "DE's" can go to hell
[00:24:48] <The_Ball> PetefromTn_, oh, so you have a 5C bed fixture, cool, what sort of tap do you use, a normal hand tap or have you got one of those short cnc taps?
[00:24:52] <andypugh> I might have to do something with the Lathe PC. It told me that the HD was going to fail imminently today.
[00:25:09] <_methods> andypugh: it's just messin with you
[00:25:10] <mozmck> andypugh: I use the search feature in the menu on cinnamon and xfce quite a bit
[00:25:11] <_methods> computers do that
[00:25:16] <andypugh> Can you still get IDE drives?
[00:25:19] <witnit> are you switching to ssd?
[00:25:35] <Tom_itx> andypugh you can get adapters if not
[00:25:39] <witnit> I keep backups of all my machines on bootable usb so i can recover very quickly
[00:25:53] <andypugh> This PC won’t biit from USB.
[00:25:58] <_methods> i never back up anything
[00:26:01] <witnit> sure it will :)
[00:26:07] <_methods> i just keep a lot of tissues around
[00:26:09] <witnit> you got a floppy drive in it?
[00:26:10] <witnit> =D
[00:26:13] -!- unfy [unfy!~Miranda@wsip-184-185-82-30.om.om.cox.net] has joined #linuxcnc
[00:26:14] <The_Ball> andypugh, I don't think so but you can get "bridges" which will convert from SATA to IDE
[00:26:17] <robinsz> andypugh, I bought another router as a project, for later int he year
[00:26:24] <andypugh> It’s a dual Xeon 1U server from 2003.
[00:26:27] <robinsz> Builerini or something ... italian
[00:26:40] <witnit> you could boot from network right>
[00:26:44] <PetefromTn_> http://i.imgur.com/x1Nl2WC.jpg http://i.imgur.com/odAMAjf.jpg http://i.imgur.com/2Vr9uGZ.jpg
[00:27:05] <robinsz> andypugh, nice big spindle, 10 tool ATC, 9 station drill , 2 horizontal drills and a slitting saw!
[00:27:08] <PetefromTn_> The_Ball The tap is a spiral flute 3 flute tap from Morse I belive
[00:27:32] <andypugh> witnit: In theory. It does seem to want to biit from network.
[00:27:49] <witnit> so there is a usb on it though
[00:28:00] <robinsz> andypugh, I didnt need it ... but it was cheap :)
[00:28:04] <witnit> you could do PXE>USB maybe
[00:28:23] <andypugh> robinsz: What more reason do you need ;-)
[00:28:48] <robinsz> andypugh, someone had cut the cabling when they ripped it out
[00:29:29] <andypugh> Hmm, this PC has “Ultra DMA/100 IDE” which sounds vaguely old-school.
[00:29:30] <robinsz> so it will need a bit of heatshrink and some soldering ...
[00:29:48] <andypugh> All wired in pink?
[00:30:19] <robinsz> Its itallian, so probably in their natioanl colours
[00:30:22] -!- sumpfralle has quit [Quit: Leaving.]
[00:30:33] <robinsz> its looks like its all mumtilcolor, so no biggie
[00:30:51] <witnit> andypugh http://www.plop.at/en/ploplinux/networkboot-linux.html
[00:31:11] <witnit> that would work from floppy or net or cd ect
[00:31:34] <robinsz> andypugh, unlike my existing router, this thing is built like a proper machine tool ... 12" x 6" box section for gantry, 1/2" wall
[00:31:37] <Tom_itx> andypugh, newegg still have PATA drives
[00:31:38] <The_Ball> PetefromTn_, nice, with the spiral flute I've heard they are better at clearing swarf, I started rigid tapping last weekend with a straight hand tap and found swarf to build up quickly. I then did multiple cycles with increasing depth, I think I used 10 passes to get 25mm/1inch so took a while and the threads were slightly loose
[00:32:04] <The_Ball> PetefromTn_, so do you do a single tap cycle straight to the bottom?
[00:32:05] <andypugh> Yeah, it’s tricky that the machine has no CD or floppy and won’t boot from USB :-)
[00:32:23] <witnit> serious boot from plops and you are set :)
[00:32:37] <robinsz> spiral machine taps will just go straight in usually, plenty of lube and away you go
[00:33:11] <witnit> you could install it on a junk hdd and then tell it to boot to usb after it kicks on
[00:33:12] <PetefromTn_> yeah just a straight tap cycle. Never tried a peck tap not even sure how to program it...
[00:33:22] <PetefromTn_> at least on the linuxCNC
[00:33:23] <robinsz> yeahm they sound risky
[00:34:07] <andypugh> I should be able to clone the HDD. I probably ought to backup the config folders. In fact I will do that now. (Oh the marvels of Wake-On-LAN)
[00:34:16] <robinsz> fluteless works OK in thinner aluminium
[00:34:21] <robinsz> with the right lube
[00:34:22] <The_Ball> PetefromTn_, cool. There isn't a peck tap cycle as far as I'm aware, I just did a while loop with increasing depth, so multiple G33.1 or what ever it is, it syncs to the index pulse so it's fine
[00:34:49] -!- mttr [mttr!~mttr@0016019a1697.cpe.westmancom.com] has joined #linuxcnc
[00:35:07] <PetefromTn_> on linuxCNC....SWEET! gonna have to try that. Can you share your code snippet so I can see how you did it?
[00:35:19] <witnit> are there any problems running a machine purely from bash to handle the machine instead of using gcode?
[00:35:29] <robinsz> doh ... mfw I downloaded and burnt a DVD .. and this PC has no DVD drive ...
[00:35:33] <witnit> so, halcmd then all the stuff you need?
[00:35:53] <andypugh> witnit: No, you can do that.
[00:36:05] <robinsz> you could ...
[00:36:15] <witnit> i was though, is that bad?
[00:36:47] <andypugh> I do lots of stuff from a halcmd session. Most of my driver development for example.
[00:37:06] <witnit> halcmd setp %@#$%#$%^WRWET FALSE; sleep.2; halcmd @#$%@#$%DSDF TRUE; sleep.5;
[00:37:13] <witnit> like that in a script
[00:38:09] <robinsz> whats about a nice ladder program and some PLC code?
[00:38:19] <andypugh> halrun / source script.hal
[00:38:20] <witnit> i dont know ladder and plx
[00:38:21] <witnit> plc
[00:38:24] <The_Ball> PetefromTn_, here you go, I just comment out the things that are not right for the cycle, first I would center drill, then peck drill, then peck tap: http://pastebin.com/YfDn6ipN
[00:39:40] <PetefromTn_> sure that is what this program is. Face off the top of the part, spot drill, run spot drill around part edge to champfer edge, then peck drill past depth of tapping op, then rigid tap and complete...
[00:39:44] <The_Ball> PetefromTn_, so I would do a manual tool change, change what commented out and do a new run
[00:39:56] <witnit> but i mean just stringing all my halcmd sessions into a bash.sh and executing it, thats np right? i was doing M102 etc with more common things which i repeat
[00:41:16] <The_Ball> PetefromTn_, yeah it's nice when you've done the programming. I've not thought about using a spot drill to chamfer, does that work well?
[00:41:40] <PetefromTn_> for this little champfer it does and saves a toolchange
[00:42:25] <The_Ball> PetefromTn_, nice I'll keep that in mind
[00:43:22] <furrywolf> grrrr. shoptask send me the wrong belt for my z axis.
[00:43:22] <andypugh> Time I was asleep. Night all.
[00:43:31] <robinsz> night dude,
[00:43:32] <Tom_itx> later andypugh
[00:43:32] -!- andypugh has quit [Quit: andypugh]
[00:43:45] <robinsz> nice to see people from wayback
[00:44:05] <robinsz> does anonimasu show his face from time to time?
[00:44:12] <Tom_itx> yes
[00:44:23] <Tom_itx> he's been working on something lately and has been here
[00:44:30] <robinsz> nice
[00:44:37] <robinsz> I see Jymm is still here
[00:44:42] <furrywolf> see, I ordered a replacement straight from shoptask to be sure I got the right one the first time, unlike measuring the length, guessing the tooth count, and ordering from the local industrial supply place. so, of course, shoptask sends me one that doesn't fit.
[00:44:49] <Tom_itx> anon is here but not here :D
[00:47:15] -!- anth0ny has quit [Quit: anth0ny]
[00:50:26] <PetefromTn_> I am NOT good at reading those Do while loops codes.... makes me dizzy ;)
[00:51:35] <The_Ball> PetefromTn_, well ignore the rest of the fluff, it's only the four lines with the o110 you want
[00:52:23] <PetefromTn_> sure
[00:53:40] <witnit> PetefromTn could you shorten that up and pass the variables for different setups using http://linuxcnc.org/docs/html/gcode/m-code.html#sec:M100-to-M199

[00:54:45] <PetefromTn_> witnit thats ball's code not mine... and I SUCK at this sort of thing. I let CAM take care of all of that mess... if the code is miles long I could give a rats ass as long as it works the way I want hehehe
[00:55:13] <witnit> The_Ball your code, can you do that thing i said up there?
[00:55:17] <Tom_itx> take the time to see what the cam is doing
[00:55:28] <Tom_itx> it will start to make sense
[00:55:31] <PetefromTn_> I do all the time...
[00:55:31] <furrywolf> pete: do you have a good free cam program to suggest?
[00:55:55] <PetefromTn_> CAM..no unfortunately... CamBam has been good to me but it is not free
[00:57:04] <witnit> http://fortwayne.craigslist.org/tls/4835628650.html yes or no?
[00:57:41] <PetefromTn_> Yes or no what?
[00:57:51] <witnit> is it a good buy?
[00:58:00] <witnit> would you guys jump on it?
[00:58:07] <furrywolf> no
[00:58:10] <PetefromTn_> I would think so if it comes with the table and you really need it..
[00:58:45] <witnit> I wouldnt say, need it, but. you know when you got the space...
[00:58:49] <PetefromTn_> I have done some wood turning on one of those before and it was decent
[00:59:11] <witnit> the cabinent is nothing special but thats okay too
[00:59:58] <PetefromTn_> It is not a very poweful machine but for it's size and whatnot it seemed to work fine. Small dia stuff should be easy
[01:00:09] <PetefromTn_> Does it come with any turning tools?
[01:00:16] <witnit> it said it did
[01:00:29] -!- Nick001-shop has quit [Quit: ChatZilla 0.9.91.1 [Firefox 30.0/20140605174243]]
[01:00:31] <PetefromTn_> a decent set of turning tools alone would cost that much
[01:01:14] <witnit> I should probably go get it, put it back up sale for 500 and use it as needed
[01:01:28] <witnit> 20 min drive away for me
[01:02:16] <furrywolf> I see wood lathes cheaply pretty often, but they don't have cabinets like that.
[01:02:24] <PetefromTn_> well ya never know man... I certainly would not pay $500.00 for it but that does not mean there is not someone who would..
[01:02:29] <witnit> looks like a pine cab
[01:02:42] <witnit> not exactly sought after
[01:03:32] <witnit> ill let you guys know if i get it :)

[01:05:47] <TekniQue> I second that, CamBam is quite good
[01:06:05] <TekniQue> and for the low amount of work I use it for the free trial lasts forever
[01:06:06] <MC500> I moved my STG ISA card to a new computer running Linux CNC 2.6 now the axis dont move, I am not getting +- voltage on DAC0-2 all configs are the same I have tried every I/O address
[01:06:23] <TekniQue> the free trial covers starting the application 40 times

[01:08:09] <witnit> this?
[01:08:35] <MC500> wow yea thats it..
[01:09:18] <SpeedEvil> Is any ISA card recognised?
[01:09:29] <MC500> I even changed out the power supply cuz the ond one only had a 4 pin CPU power supply
[01:09:31] <SpeedEvil> And is ISA bus enabled in the linux config?
[01:09:37] <MC500> yes the cards are seen by the software
[01:10:00] <furrywolf> cambam seems to come in a .msi file. what the hell is a .msi file?
[01:10:03] <MC500> not sure if ISA is enabled, didnt have to do it on the old software... whre is that done?
[01:10:17] <SpeedEvil> If the cards are seen - that's probably not an issue
[01:10:33] <furrywolf> also seems to be windows-only... and I don't have wine on this box to see if it even works.
[01:10:57] <MC500> the encoders work and display fine and I can turn the spindle on and off

[01:11:01] <witnit> 2 x ISA slots (No DMA support for ISA)
[01:11:04] <witnit> does that matter?
[01:11:20] <MC500> oh really? it may
[01:12:59] <witnit> what card are you plugging into it?
[01:13:42] <MC500> Servo to Go 2 ISA card
[01:14:56] <MC500> I didnt catch the no dma support for ISA I bet thats it
[01:16:12] <The_Ball> witnit, what do you mean, m codes do not run gcode as far as I know
[01:16:27] <witnit> do these work? http://www.diytrade.com/china/pd/3108380/PCI_to_ISA_Convertor_Module_PCM_9004.html
[01:16:39] <witnit> i know nothing about isa to pci conversion
[01:18:58] <witnit> the_ball i used mcodes to escape the gcode and call sub routines to do repetitive things like handling a momentary acuator with one command
[01:19:49] <witnit> so instead of writing it all out by hand in each gcode file, you could just call on it via mcode and pass the variables you needed with -q
[01:20:00] <MC500> no its a 16 bit card.....:(
[01:20:32] <witnit> sorry MC500 atleast we found a possible reason you are having issues
[01:21:57] <robinsz> so ,,, question
[01:21:57] <MC500> thanks for the help
[01:22:26] -!- rob_h has quit [Ping timeout: 264 seconds]
[01:22:41] <witnit> the_ball if your subroutine is dependant on a variable, and you pass an mcode with the variable in it, it writes the variable to file. now when you call your subroutine it will function with the new variable is what im trying to say
[01:22:57] <robinsz> pausing ... how easy/hard will it be to get it to do this when paused: retract spindle, spindle off. and then spindle on, wait 5 seconds, Z down .. continue
[01:24:06] <witnit> not hard
[01:24:08] <unfy> industrial boards might not be a bad idea. I-Base / IBase mad quite a few and should still
[01:24:19] <unfy> (that is modern hardware with pci/isa bus's)
[01:24:47] <robinsz> witnit, there is some scripting possible now for stuff like that?
[01:24:50] <furrywolf> I can't imagine a servo control card needing DMA.
[01:24:58] <witnit> you can call that with an mcode and pass a bash to handle it, i dont know how safe it is but its what i do
[01:25:13] <furrywolf> DMA is usually for transferring large blocks of information (disk sectors, display pages, etc) to and from memory, not a task needed for a servo card.
[01:25:23] <witnit> do you have a machine up right now?
[01:25:23] <The_Ball> witnit, what's the problem your solving with the m code? Why not just use a function call with the variables as arguments, or global variables?
[01:25:39] <robinsz> physical machine?
[01:26:09] <witnit> i use the m codes to do work outside of the program
[01:26:14] <The_Ball> witnit, o<pecktapp> #<depth> #<step> or what ever
[01:26:20] <robinsz> The_Ball, I'd like to do the following when the machine pause is pressed
[01:26:26] <robinsz> retract Z
[01:26:34] <robinsz> stop spindle
[01:26:53] <robinsz> probably stuff liek mist or vaccum off too
[01:27:52] <furrywolf> bbl, time for work
[01:27:52] <The_Ball> robinsz, for a tool change?
[01:27:53] <robinsz> then when continue, spindle start, drop back down to correct Z, off we go
[01:27:58] <witnit> I do this, M102, relay off, wait 5 seconds relay on; add 1 to the cycle program post results to website; exit;
[01:27:59] <robinsz> no, for a pause
[01:28:02] <witnit> with one mcode
[01:29:16] <robinsz> The_Ball, just a pause ... sometimes when working on 8x4 sheets on a router, its useful to be able to pause while you do something, like move a bit of scrap or some such

[01:29:41] <zeeshan|2> i need to connect a diode between pin #14 of the relay
[01:29:51] <zeeshan|2> and -24vdc rail, what is the cleanest way to do this?
[01:30:16] <The_Ball> robinsz, ah I see, and you wouldn't do this with M0 or M1?
[01:30:24] <unfy> 'clean' is arbitrary
[01:30:32] <robinsz> ??
[01:30:41] <robinsz> where woudl you enter this M0?
[01:30:53] <zeeshan|2> http://i.ebayimg.com/00/s/MTEwN1gxNjAw/z/I5kAAMXQQANREsfg/$T2eC16JHJF8E9nnC6UtNBREsfgeu9w~~60_35.JPG
[01:30:53] <robinsz> in the MDI line while it is running?
[01:30:55] <zeeshan|2> thats the diode.
[01:31:02] <zeeshan|2> its legs are exposed, im not too sure how to put it in
[01:31:14] <robinsz> might be a bit cumbersome if the operator spots somethign and just wants to pause ...
[01:31:46] <unfy> you could just push the sucker in if you don't care and the legs are fat enough to get a solid grip
[01:31:57] <zeeshan|2> hm
[01:31:58] * FinboySlick is so cold...
[01:32:02] <zeeshan|2> i don think it will reach.
[01:32:06] <witnit> you could just put a button on the machine to trigger such an event
[01:32:07] <zeeshan|2> with the diode by itself
[01:32:22] -!- furrywolf has quit [Ping timeout: 245 seconds]
[01:32:41] <robinsz> The_Ball, I was hoping just to use the pause icon on the GUI .. or even a key press
[01:32:45] <The_Ball> robinsz, why not something like this? http://pastebin.com/XhJwNWRZ
[01:32:47] <unfy> otherwise, solder it to a couple copper bars and possibly heat shrink it the solder connections. don't cover the diode (it'll get warm, and you need to see the marking for direction)
[01:33:28] <robinsz> The_Ball, no, that would require you to know in advance where you want to pause it
[01:33:34] <The_Ball> robinsz, M0 will pause until you press cycle start again, M1 allows you to toggle the conditional stop, so if you don't want pauses it will just continue
[01:33:45] <The_Ball> robinsz, yes for sure
[01:33:53] <robinsz> yes, but thats in the GCODE program
[01:33:55] <_methods> kester 44 60/40
[01:34:01] <_methods> is it the best solder ever
[01:34:33] <robinsz> im talking about pressing the pause button on the GUI ... to temporarilt stop execution ... you cant just pause the motion on a router
[01:34:36] <unfy> then only thing i like modern solder for is adding it in a 1/15 or 1/20 ratio for casting lead bullets :D
[01:34:40] <The_Ball> robinsz, so what you want is a button in the UI which you can press to pause which will then move the spindle away?
[01:34:42] <robinsz> well, you could, if you dont mind a fire
[01:34:49] <robinsz> indeed
[01:34:59] <unfy> (all that tin and a touch of antimony ? yes plz)
[01:35:06] <_methods> hehe
[01:35:12] <witnit> but how is he going to do that one the fly?
[01:35:28] <robinsz> its standard on routers
[01:35:30] -!- moorbo has quit [Remote host closed the connection]
[01:35:37] <robinsz> you cant just pause motion
[01:35:47] <robinsz> tools burn up
[01:35:57] <witnit> I think you need to add a secondary switch that will pause your machine then do sequence and unpause the machine
[01:36:06] <The_Ball> robinsz, I've not tried this myself yet, but there's a feature called 'job on pause' allowing the spindle to be moved when paused, it might be possible to shoehorn into such a feature
[01:36:15] <The_Ball> sorry, jog on pause
[01:36:26] <robinsz> yes, thats useful
[01:37:00] <robinsz> my current router does (or did ...) that
[01:37:09] <robinsz> press pause, retracts, spindle stops
[01:37:21] <robinsz> jog it out of the way, mess around with wood
[01:37:35] <robinsz> press continue, it comes back to correct x,y
[01:37:39] <robinsz> starts spindle
[01:37:42] <robinsz> drops it in
[01:37:45] <robinsz> continues
[01:37:59] <witnit> yes, you can do that exact thing with a single button that that calls your routine
[01:38:19] <witnit> or a toggle switch would be nice
[01:38:30] <robinsz> well, if it can be done with a swtich
[01:38:33] <witnit> up down style
[01:38:37] <robinsz> it can be done on screen I would think
[01:38:44] <witnit> yes it can
[01:38:50] <witnit> just make a new pause button
[01:38:53] <witnit> are you using axis?
[01:38:58] <robinsz> yes
[01:39:06] <witnit> it has a button builder
[01:39:11] <robinsz> oh nice

[01:39:30] <zeeshan|2> does it make a difference?
[01:39:36] <witnit> it could be your keyboard

[01:39:42] <witnit> or a playstation controller
[01:39:50] <witnit> one button or a touchscreen button

[01:40:35] <zeeshan|2> the hydraulic solenoid is enclosed
[01:40:46] <robinsz> keep diode as close to coil *as you can*
[01:40:52] <zeeshan|2> if i put it close to it it would float around a dirty environment

[01:44:08] <robinsz> emc/linuxcnc has really come on a long way
[01:44:10] <witnit> robinsz that will only get you the button you still need to be able to get a script to handle the machine without losing the AUTO state it is in i think
[01:44:21] <unfy> zee: conceptually on paper, yes you can do it. wire length and capacitance ... and environmental conditions could play a role etc etc etc.
[01:44:34] <robinsz> that will be the harder part
[01:44:45] <witnit> yes but not too bad
[01:45:05] <robinsz> store XYZ, stor spindle speed
[01:45:08] <witnit> Im quite sure you can do it with a very simple bash script
[01:45:19] <witnit> yes
[01:45:23] <witnit> if you know how to do it that way
[01:45:26] <robinsz> it uses bash for scripting?
[01:45:33] <unfy> zee: if it was on a pcb, i wouldn't care prolly :D
[01:45:49] <zeeshan|2> i wish it was on a din rail mounted pcb w/ terminals.
[01:45:53] <zeeshan|2> would make it a lot easier..
[01:45:53] <witnit> I do, I just pass what i need to it and the hand the controls back to the software when im done
[01:46:01] <robinsz> hmm
[01:46:14] <witnit> I made a counter
[01:46:25] <witnit> everytime you call this mcode it will add 1 to a file
[01:46:31] <unfy> make sure the wire on the top example can handle the parallel load
[01:46:42] <zeeshan|2> theyre all oversized

[01:48:27] <robinsz> its normal just to wire the diode across the terminals
[01:49:11] <zeeshan|2> i dont have any damn din rail space left though haha
[01:49:34] <zeeshan|2> so i guess it looks like my option is to sold wire at the ends of the diode
[01:49:38] <zeeshan|2> heat shrink it all and shove it in
[01:49:45] <zeeshan|2> *solder
[01:49:50] <robinsz> you normally just find them pushed in to the din rail terminals
[01:50:00] <zeeshan|2> but the legs arent long enough?
[01:50:08] <zeeshan|2> i guess they design em with that in mind.. unlike me
[01:50:28] <robinsz> depends what diode
[01:50:47] <zeeshan|2> im using a 6a4
[01:51:09] <zeeshan|2> according to spec sheet its got like 8.5-9mm legs
[01:51:13] <zeeshan|2> er 1" legs.
[01:51:23] <robinsz> kinda short
[01:52:01] <robinsz> whatever ... just bodge it in there and be done

[01:58:02] <zeeshan|2> when its all wired up :P
[02:00:03] <The_Ball> zeeshan|2, maybe check with a multimeter that the coil doesn't already have a diode built in? if it's a fully sealed unit and all
[02:00:28] <zeeshan|2> the_ball i've never used a multimeter to check for that
[02:00:50] <The_Ball> zeeshan|2, there should be a diode tester mode on most multimeters these days
[02:01:20] <zeeshan|2> the setting that says hFE?
[02:01:32] <zeeshan|2> nm
[02:01:52] <The_Ball> zeeshan|2, that's for testing transistor amplification, but does that setting have a diode icon as well?
[02:02:15] <zeeshan|2> oh there we go
[02:02:18] <zeeshan|2> i do have a diode symbol
[02:02:30] <zeeshan|2> so what do yuou do, just touch the leads and it should beep?
[02:02:53] <The_Ball> depending on the multimeter it will show you the forward drop voltage, usually 0.6-0.7v
[02:03:07] <zeeshan|2> okay so if it shows me 0 v
[02:03:11] <The_Ball> so touch the leads check for a reading, reverse the leads check for a reading
[02:03:13] <zeeshan|2> in either direction
[02:03:18] <zeeshan|2> that means there is no diode?
[02:03:39] -!- amiri has quit [Ping timeout: 256 seconds]
[02:04:28] <The_Ball> hmm, actually that probably won't work without enough current to charge the coil up to the diode's forward voltage
[02:04:49] <The_Ball> sorry, I don't think you can do it without a power source
[02:05:58] <The_Ball> if you had a constant voltage and constant current power source you would hook up the coil one way and measure the voltage over it, then reverse the wires, one of the readings would give you a low ~1V reading if there was a diode in place
[02:06:57] <The_Ball> you'd also see the powersupply switch to constant current mode if there was a diode short circuiting in one direction
[02:14:11] -!- ejb has quit [Quit: ZZZzzz…]

[03:01:36] <zeeshan|2> that makes a good diode to use vs thru hole component

[03:04:26] <furrywolf> $18.29 each?
[03:04:50] <zeeshan|2> that site is overpriced :)
[03:06:31] <furrywolf> they took a $0.05 tvss or something, stuck it in a box with siemens on the side, and added $18.24 to the price.
[03:13:28] <pcw_home> For a relay you dont really need a diode unless its more than 60 mA (a small control relay will be less than 60 mA at 24V)
[03:13:57] <Tom_itx> isn't that double current kickback or double voltage?
[03:14:40] <pcw_home> This is for 7I77 outputs which have built in clamps
[03:15:01] <furrywolf> pcw: unless you're using a board with built-in diodes, you absolutely need one per relay...
[03:15:07] <Tom_itx> you mustuv been thinking ahead :)
[03:15:09] <pcw_home> Nope
[03:15:34] <furrywolf> even a tiny relay generates a >100V spike on turn-off.... hell, I've exploited this to get a little bit of high voltage for other things...
[03:16:07] <pcw_home> the drivers have feedback zeners so fast clamps to ~40V
[03:16:07] <furrywolf> and if you're driving this off, say, a 30v or 60v mosfet, you'll blow the gate oxide. (been there, done that!)
[03:16:54] <pcw_home> Many MOSFETs are rated for this service
[03:17:07] <furrywolf> ok, maybe the drivers YOU use do... but a generic output, unless stated to have protection, should get a diode.
[03:17:44] <Tom_itx> pcw_home, there's no problem configuring the 7i90 for 2 7i47 is there?
[03:17:53] <Tom_itx> since i think the one i have is good now
[03:18:12] <pcw_home> No should not be an issue
[03:18:14] <Tom_itx> won't need all the stepgen etc stuff
[03:18:15] <furrywolf> I have blown gate oxide doing that... first they get leaky between drain and gate, then the stop working... and often whatever was driving the gate gets fried too!
[03:18:21] <Tom_itx> mostly for gpio

[03:48:51] <Sairon> truly
[03:51:37] <furrywolf> I should work on the milling machine, but I'm too tired.

[04:08:56] <pcw_home> zeeshan|2 possible but with limitations: no physical index, limited count rate, TTL only
[04:09:02] <furrywolf> I guess I could go that route instead of a mesa board... stuff a mini-itx in the control box, and run the ui remotely.
[04:09:06] <zeeshan|2> hm
[04:10:15] <Sairon> damn
[04:10:16] <Sairon> wtf
[04:10:25] <Sairon> is that an $83 motherboard
[04:11:04] <zeeshan|2> are TTL
[04:11:11] <Sairon> when i see how cheap computers are these days
[04:11:11] <zeeshan|2> and NPN or PNP outputs the same thing?
[04:11:16] <Sairon> i just want to spit and curse
[04:11:17] <zeeshan|2> i know npn and pnp are different
[04:11:30] <zeeshan|2> or is TTL a combination of the two
[04:11:31] <Sairon> i bought ram for my laptop and it just blew my mind
[04:11:35] <Sairon> how cheap the stuff is
[04:12:26] <pcw_home> TTL in this case means single ended ~1.6V threshold
[04:12:33] * furrywolf remembers when a 16K ram board cost as much as a new car...

[04:13:19] <zeeshan|2> what is this? :)
[04:13:30] <Sairon> it's like telling someone they can have a trillion dollars
[04:13:46] <zeeshan|2> that outputs 5v dg on output 1 and 2.
[04:13:51] <zeeshan|2> dg = dc
[04:14:10] <furrywolf> looks like a quadrature sensor, just a guess...
[04:15:03] <zeeshan|2> last time i asked pcw about this
[04:15:09] <furrywolf> (guess based entirely on the shape of the module and having two outputs)
[04:15:12] <AR__> zeeshan|2, http://www.farnell.com/datasheets/1795491.pdf
[04:15:12] <zeeshan|2> he said something about needeing a 200 ohm resistor mto make it work w/ the encoder inputs
[04:15:26] <zeeshan|2> AR__: i stole that image from there :)
[04:15:53] <AR__> o
[04:16:29] <furrywolf> if it's open-emitter output, then put a 1K resistor to ground. or maybe 4.7K...
[04:16:46] <zeeshan|2> those words too to technical for me
[04:16:49] <zeeshan|2> :)
[04:16:55] <pcw_home> looks like it just has true and inverted outputs
[04:17:14] <furrywolf> or is it still open collector when it's pnp? brain too tired.
[04:17:17] <pcw_home> not quadrature
[04:17:19] <zeeshan|2> which pin would i connect to the enc a
[04:17:24] <zeeshan|2> pin
[04:17:32] <zeeshan|2> qa i mean
[04:17:35] <zeeshan|2> qb and idx
[04:17:44] <zeeshan|2> obv i have 3 of these :P
[04:17:46] <furrywolf> if they're just inverted outputs, pick whichever one you want.
[04:17:54] <zeeshan|2> just unsure which wire goes to the encoder inputs
[04:18:09] <furrywolf> just pick the same one for all three, although linuxcnc can compensate in software no matter how you do it.
[04:18:38] <zeeshan|2> im planning to tie all the +24vdc together for each sensor
[04:18:43] <zeeshan|2> and 0v ..
[04:18:43] <furrywolf> is your index pulse solid or a slot? and do you want it to go high or low?
[04:18:46] <zeeshan|2> to save on wires
[04:18:56] <zeeshan|2> furrywolf: everything will be a slot
[04:19:08] <furrywolf> ok, and when that slot is sensed, do you want it to go high or low?
[04:19:09] <zeeshan|2> i'm just confused whether if i hook up output 1.. to qa
[04:19:10] <pcw_home> dont wire 24V signals to the normal encoder inputs
[04:19:13] <zeeshan|2> will it notice a change?
[04:19:28] <zeeshan|2> pcw_home: it doesnt output 24vdc
[04:19:34] <zeeshan|2> it outputs 5vdc
[04:20:04] <furrywolf> not according to that diagram it doesn't.

[04:20:41] <zeeshan|2> okay then theres no need to give it 24vdc
[04:20:58] <zeeshan|2> ill just use the +5v out of the encoder header at 7i77
[04:21:17] <furrywolf> so when you get the index slot, do you want the input to go high or low?
[04:21:28] <zeeshan|2> furrywolf: it doesnt matter i can change that in linuxcnc
[04:21:34] <zeeshan|2> (i dont know yet)
[04:21:37] <furrywolf> if you want it to go high, use the black wire, with a 1k resistor to ground.
[04:21:44] <pcw_home> but it will need a stiff pulldown (since the 7I77 encoder inputs in TTL mode have a 2K pullup)

[04:22:18] <furrywolf> ouch. fighting a pullup with a pulldown is a bad idea.
[04:22:19] <pcw_home> No
[04:22:29] <zeeshan|2> ok ill buy a npn then

[04:24:51] <furrywolf> the npn will be much easier to wire. no pullups/downs needed if the board has a built-in pullup, and you can feed it any voltage you want.

[04:28:37] <furrywolf> you should only twist differential signals together. twisting unrelated things doesn't help. if you want to use twisted pairs, twist each one with ground.
[04:28:54] <furrywolf> twisting unrelated things causes crosstalk
[04:29:18] <zeeshan|2> yea but it helps with external noise?
[04:29:28] -!- racicot has quit [Changing host]
[04:29:28] <furrywolf> no
[04:29:47] <zeeshan|2> okay ill just use shielded cable
[04:29:58] <pcw_home> it will create crosstalk with A/B/Z
[04:30:03] <furrywolf> twisting helps with noise on differential signals because the noise affects both sides equally, and they cancel out... with a single-ended signal, it's not going to help.
[04:30:08] <furrywolf> shielded cable definitely helps.
[04:31:46] <pcw_home> on linuxcnc 2.6.x the encoder input filtering can be adjusted so it possible to reject most impulse noise

[04:40:33] <XXCoder> furrywolf: cpu cooler

[04:41:16] * zeeshan|2 hides
[04:41:35] <XXCoder> I want to make air liquifier too but I am far less skilled and mhas much less tools too bahh
[04:41:39] <furrywolf> because if you're extracting useful energy, you're raising the thermal resistance between the cpu and the air, causing higher cpu temps.
[04:41:46] <XXCoder> its not making energy
[04:41:54] <zeeshan|2> googlez stirling engine
[04:42:02] <furrywolf> so the fan runs off non-energy? :P
[04:42:07] <XXCoder> its pretty clear you need some stirling homework
[04:42:17] <XXCoder> stiring = heat engine
[04:43:06] <furrywolf> a heat engine works on a thermal gradient/temperature DIFFERENCE. not just magically off heat.
[04:43:29] <XXCoder> well theres plenty of difference for type c between cpu and air
[04:43:35] <XXCoder> expecially with heat sink
[04:43:50] <XXCoder> properly made type C can run off your hand
[04:44:05] <furrywolf> in that case, it works on the temperature difference between its base, contacting the cpu, and the air, on the heatsink on top of the cylinder. but if you got rid of the stirling engine and just put the heatsink on the base, it'd cool better...
[04:44:14] <zeeshan|2> whats type c
[04:44:15] <XXCoder> nope
[04:44:22] <XXCoder> zeeshan|2: theres 3 types of stirling
[04:44:41] <zeeshan|2> yea but i havent heard of type c
[04:44:46] <zeeshan|2> does it have another name
[04:44:47] <XXCoder> a, b, c. a has seperate pisions and enclosures, b is one you saw in nigrogen maker
[04:44:52] <XXCoder> c is weird one
[04:44:58] <XXCoder> nope
[04:45:10] <zeeshan|2> wiki shows alpha beta gamma
[04:45:12] <furrywolf> there's more than 3... I invented a double-coaxial setup with two systems working 180 degrees apart, intended for designs with a large physical separation between the hot and cold ends... :P
[04:45:25] <Sairon> hmm
[04:45:45] <Sairon> i seem to remember sterling engines don't need good seals around the pistons
[04:45:49] <zeeshan|2> furrywolf: youre right
[04:45:52] -!- ariscop has quit [Ping timeout: 240 seconds]
[04:45:55] <zeeshan|2> in the sense it needs testing.
[04:46:04] <witnit> turning the fan alone is a form of energy conversion from heat to motion.......
[04:46:10] <Sairon> at least the ones with the really long, opposed pistons
[04:46:14] <zeeshan|2> these sort of systems have a transition point where it makes sense
[04:46:16] <zeeshan|2> and where it doesnt
[04:46:28] <furrywolf> it may well work, but eliminating the stirling motor and sticking the heatsink right on the base will cool better... any time you're extracting energy, you're increasing the thermal resistance.
[04:46:47] <XXCoder> zeeshan|2: actually youre right, I somehow remembered c when its actually gamma
[04:46:57] <zeeshan|2> furry it depends
[04:47:10] <zeeshan|2> there might be a breakeven point on the area of the piston blocking the heatsink
[04:47:13] <zeeshan|2> vs convection
[04:47:15] <furrywolf> I also question the lifespan... even a good ball-bearing brushless fan dies in a few years of continuous use, and it doesn't have seals to wear.
[04:47:28] <furrywolf> zeeshan: an electric fan is the obvious answer. :P
[04:47:41] <XXCoder> furrywolf: I can see some uses though
[04:47:44] <zeeshan|2> convection is has a way higher heat transfer coefficient
[04:47:48] <zeeshan|2> than pure conduction
[04:47:53] <XXCoder> for example projector fan that does not die with power out
[04:47:54] <zeeshan|2> i bet this thing has merit to some point
[04:48:04] <furrywolf> now, if you really wanted fun, you could connect the electric motor to the stirling engine, which will cause the stirling engine to work as a heat pump instead of a heat engine, and actively try cooling the cpu below ambient... :P
[04:48:05] <XXCoder> so bulb lives blackout
[04:48:33] <witnit> regardless you can chase the heat toward the higher end of the heatsink and cool the areas closest to the cpu
[04:48:45] <XXCoder> furrywolf: heh I do want to get nice type beta to make liquified air
[04:49:56] <XXCoder> http://sunpowerinc.com/
[04:50:14] <furrywolf> I should build my design one of these days... it's designed to have the hot end and the cold end physically separated, possibly even with flexible lines between them, while still being efficient... needs a high-surface-area heat exchanger and other fun bits.
[04:50:30] <XXCoder> isnt sealed air requirement?
[04:50:36] <XXCoder> working air
[04:50:48] <furrywolf> no, as long as air is your working fluid, you can leak as much as you want... just lowers efficiency.
[04:50:57] <furrywolf> since it'll suck air back in through the same leaks
[04:51:22] <zeeshan|2> im happy you guys are talking about something viable
[04:51:27] <zeeshan|2> and not some perpetual motion bs

[04:54:26] <zeeshan|2> yea im wrong
[04:54:29] <zeeshan|2> i was thinking of something else.
[04:54:36] <furrywolf> I might do stirling if I ever move to an area with enough direct sunlight to try my fresnel parabolic trough solar collector idea...
[04:54:45] <zeeshan|2> n = 1 - tc/th

[04:57:45] <XXCoder> car engine applies surpising little heat to tires
[04:57:57] <unfy> xxcoder: i... dunno if wanna do that yet.
[04:57:59] <zeeshan|2> been mostly doing structural
[04:58:15] <furrywolf> I do a little bit of everything...
[04:58:17] <XXCoder> me either lol
[04:58:59] <furrywolf> when I get my mill working, I want to play around with building hydraulic pumps and motors next.
[04:59:09] <zeeshan|2> im suprised
[04:59:15] <zeeshan|2> i thought you'd be building dildos or something
[04:59:20] -!- tjtr33 [tjtr33!~tjtr33@73.22.99.22] has parted #linuxcnc
[04:59:26] <zeeshan|2> scared tj away
[05:00:09] <furrywolf> who said I couldn't build a fucking machine too? :P
[05:00:52] <XXCoder> heh I need a lot to go before I can
[05:02:35] <furrywolf> before you can build dildos?
[05:02:41] <Sairon> dildos are easy
[05:02:44] <XXCoder> even that much yes
[05:02:48] <XXCoder> no lathe lol
[05:03:00] <Sairon> carve that shit out of wood with a knife
[05:03:06] <Sairon> watch out for splinters
[05:03:08] <XXCoder> probably can build stirling beta with almost just lathe
[05:03:41] <furrywolf> sairon: commercially available wooden dildos are made from very tight grained hardwood, and generally varnished. heh.
[05:03:53] <Sairon> gtfo
[05:03:54] <XXCoder> wow more experence I see
[05:03:55] <Sairon> really/
[05:04:04] <zeeshan|2> on that note, time for bed
[05:04:05] <zeeshan|2> :-)
[05:04:08] <Sairon> ha1
[05:04:09] <XXCoder> lol night
[05:04:20] <furrywolf> you can build a stirling with off-the-shelf parts... I have some airpel pneumatic cylinders that use a graphic piston in a glass bore.
[05:04:28] <furrywolf> graphite
[05:04:39] <furrywolf> I've always wanted to try turning one into a stirling engine. :P
[05:05:00] <XXCoder> really? besides beer or cans ones, never saw off shelf stiring howto
[05:05:04] <XXCoder> make one>? heh
[05:07:23] <furrywolf> http://www.airpot.com/ those people make pneumatic rams with graphite in glass designs... ultra low friction, and should be suitable for conversion into a stirling engine... and they're often dirt cheap on ebay, pulls from used automation equipment.
[05:07:46] <furrywolf> http://www.airpot.com/antistiction-air-cylinders.html
[05:08:10] <furrywolf> "unparalleled low friction, responding to forces as low as only a few grams and pressures less than 0.2 psi"
[05:09:05] <furrywolf> the ones I have are such low friction, that you only need to tilt them a couple degrees from horizontal for the piston to slide to the opposite end of the cylinder
[05:09:35] <XXCoder> wow
[05:09:43] <XXCoder> makes for pretty effecient stirling
[05:09:51] Audioburn is now known as il
[05:09:53] <XXCoder> too bad I has no skill to convert em. without guide anyway
[05:11:43] <furrywolf> well, first you need to think about how a stirling engine works...
[05:12:07] <XXCoder> yeah issue is im no engineer
[05:12:28] <furrywolf> sairon: http://www.coroflot.com/beneligni_holzdildo/holzdildo-wooden-dildo even has pictures on how to make one by hand. :P
[05:12:51] <furrywolf> interestingly, if you search for wooden dildos, google tries making you search for wooden dollhouses instead.
[05:13:05] <Sairon> not clicking on that
[05:13:06] <XXCoder> google used to be awesome
[05:13:08] <Sairon> but
[05:13:13] <Sairon> the google thing is funny
[05:13:19] <furrywolf> for someone who's not an engineer, you sure have strong opinions on how everyone else is wrong on engineering topics. :P
[05:13:33] <Sairon> eh
[05:13:33] <XXCoder> they now use different method than orginial. I love how orginal worked and I could work google magic
[05:13:36] <XXCoder> now its pos
[05:13:38] <Sairon> define engineer
[05:14:03] <XXCoder> designer and builder of mechism (sorry cant think better words tired now lol)
[05:14:11] <Sairon> oh, ok
[05:14:16] <furrywolf> sairon: there's nothing on that page other than generic basic woodworking shots
[05:14:55] <zeeshan|2> hey guys
[05:14:58] <zeeshan|2> did i show you the video
[05:15:03] <zeeshan|2> i know im supposed to be sleeping
[05:15:06] <zeeshan|2> but this video
[05:15:13] <XXCoder> sleepttyper!
[05:15:17] <Sairon> is it a wooden dildo video?
[05:15:22] <zeeshan|2> https://www.youtube.com/watch?v=R0fMyUXDMV0
[05:15:29] <zeeshan|2> this is what im working on for my research thesis
[05:15:53] <zeeshan|2> need to coat a dildo with that.
[05:15:56] <XXCoder> with you used a stand
[05:16:04] <XXCoder> for camera

[05:16:20] <zeeshan|2> buy me one
[05:16:44] <XXCoder> almost worth it but not good timing lol
[05:16:47] <Sairon> i watched it with no sound
[05:16:48] <XXCoder> my brain sucks
[05:16:49] <Sairon> so...
[05:16:53] * furrywolf isn't going to try dealing with youtube without a description of what the video is and how useful it is
[05:16:56] <Sairon> is it a special polymer?
[05:17:17] <XXCoder> yeah no speakers here, never needed one as me deefy :P
[05:17:18] <Sairon> i feel like i'm missing something
[05:17:36] <zeeshan|2> yea
[05:17:37] <zeeshan|2> it is
[05:17:40] <furrywolf> sairon: lots of companies make wooden dildos... I've never bought one. I like silicone. and stainless. the njoy pure wand is amazing. :P
[05:18:29] <Sairon> eh. i've heard the sex equipment business is quite profitable
[05:19:15] <XXCoder> heh sex is profitable im sure
[05:19:29] <furrywolf> it must be... I think I spent $85 on the pure wand...
[05:19:47] <Sairon> huh.
[05:19:58] <Sairon> oh1 i know!
[05:20:07] <Sairon> internet of things
[05:20:09] <Sairon> dildo
[05:20:15] <furrywolf> ?
[05:20:22] <Sairon> fucking hell, get me a kickstarter campaign
[05:20:33] <Sairon> i'm making dildos that tweak and all that
[05:20:38] <Sairon> er, tweet
[05:20:47] <Sairon> i'm gonna connect dildos to the internet
[05:20:52] <Sairon> to ... do... something
[05:20:57] <furrywolf> already been done.
[05:21:00] <Sairon> damn
[05:21:04] <Sairon> shit, really/
[05:21:17] <XXCoder> dilios that print more dilios? :P
[05:21:23] <Sairon> ha
[05:21:23] <furrywolf> starting with, thinks... it was the irabbit or something like that, way back in the '90s, with a genuine 9-pin serial port.
[05:21:39] <Sairon> dang, you seem to know a lot about dildos
[05:22:03] <furrywolf> when you like women, and like penetrative sex, that tends to happen.
[05:22:22] <Sairon> i like women
[05:22:26] <Sairon> and penetrative sex
[05:22:37] <toastyde1th> step yo game up
[05:22:37] <Sairon> but i don't know anything, really, about dildos
[05:22:40] <furrywolf> you know what I mean. :P
[05:22:50] <furrywolf> well, get one, and then you'll know more. :P
[05:22:55] <Sairon> true
[05:23:29] <XXCoder> you a man or lady fur
[05:24:27] * furrywolf is soft and fluffy
[05:25:20] <Sairon> what just happened?
[05:25:49] <zeeshan|2> soft and fluffy to me means chubby
[05:25:50] <zeeshan|2> haha
[05:26:02] <Sairon> lol
[05:26:19] <furrywolf> no. lol
[05:26:19] <XXCoder> heh
[05:26:48] <Sairon> to me it means "pillow"
[05:26:59] <XXCoder> well youre probably first furry I ever met. I think furry is strange thing but whatever as long as everyone consented
[05:27:08] <XXCoder> if I take what you said correctly
[05:27:44] <Sairon> oh, furries
[05:27:50] <furrywolf> as it turns out, furry doesn't have much to do with sex, despite what you're implying with the "as long as everyone consented".
[05:27:53] <Sairon> we have that convention here every year
[05:28:03] <XXCoder> yiff yiff
[05:28:07] <XXCoder> but yeah
[05:28:38] <Sairon> anthrocon
[05:28:44] <XXCoder> we tend to hear more about mproe perverted of any groups

[05:49:39] <PetefromTn_> so pleased with the Cincinatti tonight.... rigid tapped a SHITE load of holes and never missed a beat. KICK ASS hehe
[05:51:25] <PetefromTn_> finished this project and just got some deburring and cleaning up with brushed finishing to do and it is onto the next one
[05:51:52] <witnit> OHHHHHH YEAAHH!!! =D
[05:52:07] <PetefromTn_> :D
[05:52:17] <PetefromTn_> thanks nit hehe
[05:52:48] <Sairon> good deal
[05:52:57] <PetefromTn_> If I actually had the damn toolchanger working this would have been a fun project but even changing tools manually it was not too bad.
[05:53:01] <witnit> success feels amazing hahaha best when others understand what such a feat can mean to someone
[05:53:47] <PetefromTn_> Tomorrow I gotta finish the deburring and then I have a small prototype job to do for a customer. Kind of a neat plate job. simple and should go quickly with just a single tool
[05:54:12] <PetefromTn_> hell yeah man you don't know how long I have wanted to have a machine like this running reliably.
[05:54:21] <PetefromTn_> to me it is a VERY big deal.

[05:55:03] <The_Ball> PetefromTn_, what wasn't running reliably before?
[05:55:45] <PetefromTn_> nothing....well this is a complete retrofit of a commercial VMC. I bought it and had a lot of trouble from the original control and decided to completely gut it electronically and start over with LinuxCNC
[05:56:19] <PetefromTn_> after dumping a couple grand into the repair parts for the original control I got tired of it.
[05:56:31] <The_Ball> yeah, nice
[05:56:44] <PetefromTn_> now it is back together again for the last few months and has been working great so far.
[05:57:31] <PetefromTn_> It is still not finished yet and has a few little things remaining to be completed but I am still using it daily for my business.
[05:59:47] <The_Ball> awesome, wish I could open a one-man machine shop
[05:59:56] <witnit> do it
[06:00:00] <witnit> you could :)
[06:00:07] <PetefromTn_> it has NOT been easy let me tell ya.
[06:00:08] <XXCoder> back for a min
[06:00:14] <XXCoder> how do you get jobs anyway
[06:00:15] <XXCoder> for cnc
[06:00:22] <XXCoder> meaning orders etc
[06:00:27] <The_Ball> PetefromTn_, I believe that
[06:00:30] <XXCoder> unless your company secret
[06:00:35] <XXCoder> *its a
[06:00:52] <witnit> I did cold contacting and then the rest of my job came through the gravevine
[06:01:04] <witnit> grapevine*
[06:01:36] <PetefromTn_> no secret...just beat the fuckin' ground and knock on every damn door smiling like a salesman and try to get work wherever possible. I STILL have a lot of times when I have nothing to do but it seems to be getting better lately.
[06:02:15] <PetefromTn_> I REALLY enjoyed using that little 5c Collet closer today.
[06:02:17] <XXCoder> cool
[06:02:28] <The_Ball> PetefromTn_, best of luck, how long have you been doing it, I hear 5-10 years to build a reputation
[06:02:36] <XXCoder> its sounding more and more like job offer fell though because theyre concerned about interpeting
[06:02:39] <PetefromTn_> it is a stout little thing and after some teething problems worked great.
[06:02:46] <XXCoder> its one of very few times being deaf sucks
[06:02:52] <PetefromTn_> Thanks ball
[06:03:03] <XXCoder> 80% of deaf is unemployed
[06:03:13] <XXCoder> im actually one of 20%
[06:03:16] <witnit> :)
[06:03:22] <witnit> 100% deaf?
[06:03:26] <PetefromTn_> I found that the little handle despite having three setscrews on it is NOT enough to hold the clamp tube.
[06:03:28] <XXCoder> completely
[06:04:17] <The_Ball> XXCoder, sorry to hear that, can I ask if really loud noises are still somehow painful or not at all?
[06:04:18] <PetefromTn_> so I wound up drilling a little pocket in the side of the tube for one of the setscrews to go into the body of the tube and let the other two do the clamping. That fixed the slipping.
[06:04:29] <XXCoder> The_Ball: only physical damage ones
[06:04:48] <XXCoder> I sure as heck can feel the puncher machine chug along LOL
[06:05:01] <witnit> I thought about building a control system for the disabled, not the deaf but it is an encoder for the rotation in a chair and encoder for the front to back rocking motion, so one can control the mouse with their body, yet type with the good arm and click left right with foot pedals :)
[06:05:26] <PetefromTn_> then I found that using it vertically against my big slotted cast iron angle plate the little stop pin you use to lock the angle can fall out under some vibration of the cut
[06:05:34] <PetefromTn_> that was interesting...LOL
[06:05:39] <XXCoder> only difference for pure deaf like myself is dont bother with speakers
[06:05:52] <XXCoder> of course im actually pretty rare. most deaf has small amount of hearing left
[06:06:00] <witnit> but you can use vibration
[06:06:13] <XXCoder> for?
[06:06:14] <PetefromTn_> so I grabbed a little piece of Tig wire and belt it into a little U shape and locked it thru two of the adjacent holes to hold the pin in place.
[06:06:20] <witnit> with if you can associate vibration with sound
[06:06:29] <XXCoder> it dont work like that witnit
[06:06:33] <witnit> you can have more awareness
[06:06:42] <XXCoder> I grew up deaf. my brain never grew the hearing parts
[06:06:47] <XXCoder> and you need those to interpet
[06:07:10] <The_Ball> witnit, lol, I think you need to trust XXCoder here
[06:07:43] <witnit> I was just thinking you would be able to convert audio into vibration and orient direction with it
[06:08:49] <Sairon> naw, convert audio in to electric pulse
[06:08:57] <XXCoder> taser
[06:09:00] <Sairon> right
[06:09:06] <witnit> basically :)
[06:09:21] <witnit> wear a belt with electrodes all the way around
[06:09:24] <The_Ball> But other senses heighten as they are used more, I remember seeing on tv a blind person in a airbaloon able to tell when they were rising/falling better than the baloonist
[06:09:41] <witnit> if someone fired a gun you would feel the direction it comes from
[06:09:46] <XXCoder> The_Ball: I cant smell but I can taste more than people who cant smell
[06:10:07] <Sairon> to be fair witnit
[06:10:13] <XXCoder> and my vision... well its freaking annoying
[06:10:14] <Sairon> you feel the direction of a gunshot
[06:10:19] <Sairon> without being able to hear
[06:10:29] <Sairon> don't shoot guns much, i take it
[06:10:29] <XXCoder> everyone has around 180 degree vision, but I use pretty much all of it
[06:10:46] <XXCoder> ny focus area is well over twice space as average
[06:11:17] <witnit> you dont shoot guns much?
[06:11:40] <XXCoder> I dont shoot guns period
[06:11:54] <The_Ball> XXCoder, you mean your sharp sight is wider or your area of attention is wider?
[06:11:57] <witnit> my neighbor had all these bullet making machines we shot sooooo much
[06:12:04] <XXCoder> The_Ball: both
[06:12:11] <witnit> buckets of lead
[06:12:39] <XXCoder> which makes it bit distracting sometimes. I could read other person test paper while staring stright down to my paper. I had to carefully ignore others
[06:13:05] <XXCoder> thats why I tended to try get ends of table so that's ha;lf distraction lol
[06:13:21] <The_Ball> XXCoder, wow, never heard of anyone being able to do that
[06:13:33] <The_Ball> I've tried, lol
[06:13:33] <XXCoder> its not percise but yeah can
[06:13:54] <witnit> so you can look your wife in the eye and watch a hottie bend over at the same time...
[06:13:57] <witnit> glorious
[06:14:14] <XXCoder> not much of eye wanderer here
[06:14:17] <XXCoder> well
[06:14:28] <XXCoder> time to sleep, dont wanna sleep at 1 am again and wake 5 am uggh
[06:14:41] <The_Ball> sleep well

[15:55:51] <mrsun> making a realy long straight measuring bench ... think that 3 points and a machine level could get me there? =)
[15:56:22] <mrsun> a precision profile (rectangular steel profile) and 3 points on it to push it/pull it in line .. then move around machinist level to make it dead straight
[15:57:18] <ssi> depends how precise you need it
[15:58:02] <mrsun> noticed that my X axis on the machine is bent ... and might need due to my brain straighten it :P
[15:58:26] <mrsun> so need a dead straight comparation surface =)
[15:58:35] -!- norias has quit [Ping timeout: 265 seconds]
[16:00:53] <mrsun> but i guess there will be more parameters .. twist in the profile etc :/
[16:01:18] <mrsun> 6 bolts ... to also be able to take twist out of the sucker :P
[16:02:05] <ssi> more than that, you'll have convexity/concavity between your bolts, and general lack of flatness
[16:02:28] <mrsun> meh .. true that also :P
[16:02:43] <malcom2073> Could price out used grainte slabs
[16:02:54] <malcom2073> they're in the $300-$400 range for a 4'x4'
[16:03:24] <alex____w> friends have bought new 2x4 granite surface plates for under $200
[16:03:34] <alex____w> though i haven't seem them that cheap again for a while
[16:03:35] <mrsun> i know my rails was bent .. i hoped my beams would be able to move them straight .. but aparently not :/
[16:03:47] <mrsun> i guess some flame straightening of stuff is in order
[16:03:54] <alex____w> is your machine a cnc router?
[16:03:59] <mrsun> alex____w: yes
[16:04:14] * SpeedEvil passes mrsun a large hammer.
[16:04:28] <mrsun> SpeedEvil: haha .. to uncontrolled =)
[16:04:31] <malcom2073> Just be careful, that your U shape doesn't turn into a W shape :)
[16:04:51] * Loetmichel switched the hamemr to a copper hammer with birdshot inside
[16:05:29] <mrsun> malcom2073: hehe ... i was almost thinking of heating the whole side of the rail (the side that i want it bent towards ...) fast with a torch ... to get an even bend back =)
[16:05:36] <malcom2073> also don't forget to re-harden if you get them above the annealing temp.
[16:06:08] <mrsun> as it was a L profile that i cut 25mm off one side of ... so the internal stresses bent the profile
[16:06:14] <mrsun> when they were released =)
[16:06:19] <mrsun> malcom2073: just ordenary angle iron
[16:06:23] <mrsun> so no problem there =)

[16:58:52] <PetefromTn_> Hey guys got a hardware question for you.... I am looking for a funky threaded nut that I have seen used in different applications.
[16:59:19] <PetefromTn_> basically it is a dowel pin that is drilled and tapped thru the center along its length crosswise
[16:59:41] <Jymmm> hang on
[16:59:47] <PetefromTn_> so that it can be inserted into a machined hole and then a screw threaded into it from the side thru a clearance hole in the material
[16:59:57] <Jymmm> hang on
[16:59:59] <PetefromTn_> I cannot think of what you would call that..
[17:00:08] <Jymmm> hang on
[17:00:23] <Jymmm> http://www.amazon.com/12-Cross-Dowels-Barrel-Nuts/dp/B00BOZ7NGE
[17:00:40] <PetefromTn_> sweet thanks..
[17:00:45] <malcom2073> I was actually just thinking about those
[17:00:47] <PetefromTn_> cross dowels barrel nuts
[17:00:52] <malcom2073> Thinking of using large ones to hold together my frame
[17:00:57] <Jymmm> just cross dowel nuts
[17:00:58] <PetefromTn_> I have an application that would be perfect for these
[17:01:05] <Jymmm> primarily used in furniture
[17:02:10] <Jymmm> another http://www.homedepot.com/p/Unbranded-1-4-in-20-x-16-mm-Zinc-Plated-Type-D-Cross-Dowel-Nut-4-Pieces-54554/202105595
[17:02:21] <PetefromTn_> I see that is there an application for metal? I have been given a project to machine a couple hundred clamp style things and I was thinking something like this would be better than drilling and tapping into aluminum for longevitys sake..
[17:02:28] <Jymmm> But shitty "Crown Bolt" version
[17:02:58] <PetefromTn_> I don't even need the end machined just the threaded hole in the center
[17:03:28] <Jymmm> PetefromTn_: just google "cross nut"
[17:03:50] <Jymmm> 1/4"-20 is common thread
[17:04:34] <PetefromTn_> yeah already done.

[17:07:04] <zeeshan|2> nicee

[17:07:26] <PetefromTn_> no just hand coded the bastard...
[17:07:32] <zeeshan|2> especilly on bikes
[17:08:00] <zeeshan|2> nice setup pete
[17:08:10] <PetefromTn_> this part is all aluminum the only piece I want steel is the cross dowel pin to ensure the threaded hole will last for a LONG time...
[17:08:12] <Jymmm> zeeshan|2: Until they learn what a stop sign is, I don't care.
[17:08:29] <zeeshan|2> Jymmm: haha
[17:08:35] <zeeshan|2> damn bikers
[17:08:54] <PetefromTn_> plus with a steel cross dowl pin and a shcs bolt it should allow more tension on the clamping..

[17:31:06] <roycroft> i have a couple of those
[17:31:09] <roycroft> they work fine
[17:31:35] <roycroft> as shipped they are not true pid controllers, but there is pid code that can be burned into them easily
[17:31:43] <Jymmm> roycroft: there are shitloads of 220VAC out there
[17:31:58] <roycroft> the st1000 is also available in 110vac
[17:32:05] <roycroft> which are the ones i have actually
[17:32:16] <roycroft> i saw someone mention 220vac, so i posted that link
[17:32:29] <Jymmm> That was the 1st 12VDC I've seen under 2" sq
[17:32:34] <roycroft> i'm not sure what the application is, because i wasn't around for the beginning of the discussion
[17:32:35] <Jymmm> =)
[17:33:07] <Jymmm> roycroft: Just for whatever or automotive, livestock, etc
[17:33:29] <Jymmm> roycroft: for $4 you can't beat it
[17:34:02] <Jymmm> backup temp alarm, etc
[17:34:14] <Jymmm> for like freezer
[17:34:24] <roycroft> i use these on my brew system:

[17:34:28] <roycroft> they work great
[17:34:54] <malcom2073> It's artificial intelligence enhanced pid!
[17:34:59] <roycroft> it takes a while for them to train up on the system, but that only needs to be done seasonally
[17:35:47] <roycroft> they're overkill for many applications, of course
[17:36:22] <malcom2073> I'm actually looking for a temp controller to make a heated enclosure
[17:36:38] <malcom2073> 1250watt 110v heater coil
[17:36:54] <roycroft> how closely do you need to control the temperature?
[17:37:07] <malcom2073> Not a clue, I'll find out if it makes a difference :)
[17:37:23] <Jymmm> malcom2073: what are you heating and why?
[17:37:28] <malcom2073> I expect the tighter the control, the better
[17:37:40] <malcom2073> Jymmm: *whispers* 3d printer chamber
[17:37:41] <PetefromTn_> tjtr33 https://www.youtube.com/watch?v=yw9gWlpdQoI This is a nice homebuilt trike I was intersted in
[17:37:48] <roycroft> if so, then use a pid controller
[17:37:57] <malcom2073> yeah
[17:38:11] <PetefromTn_> oops sorry wrong forum LOL
[17:38:22] <Jymmm> malcom2073: Yeah, what roycroft said, but not a $50 one, maybe a $20 one
[17:38:49] <roycroft> and if you're comfortable soldering a couple wires on a pcb, get one of those stc1000 controllers and push the pid code onto it
[17:39:14] <Jymmm> malcom2073: http://www.ebay.com/itm/New-RNR-PID-Digital-Temperature-Control-Controller-1-Alarm-Relay-Output-TC-RTD/271660193617?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D777000%26algo%3DABA.MBE%26ao%3D1%26asc%3D20131227121020%26meid%3D6e0fb840e0be4c468623e7ac4a37fe41%26pid%3D100009%26prg%3D20131227121020%26rk%3D1%26rkt%3D4%26
[17:39:17] <malcom2073> I am, I thought about using an arduino with a SSR I have laying around, which is how I tested the heater in the first place, pwming it at different rates to find out power consumption
[17:39:21] <Jymmm> malcom2073: ships from USA
[17:39:28] <malcom2073> Nice, cheap too
[17:39:39] <roycroft> iirc the stc1000 can swith up to 15a directly, so you would not need a relay/ssr with it
[17:40:06] <malcom2073> roycroft: http://www.amazon.com/Digital-All-purpose-Temperature-Controller-STC-1000/dp/B00862G3TQ that?
[17:40:34] <malcom2073> Yo usaid push code, what micro does it use?
[17:41:14] <roycroft> i think it's an atmel, but i'm not sure
[17:41:56] <roycroft> i'm looking for a link to the pid code project - give me a moment

[18:44:06] <CaptHindsight> zeeshan|2: what material and what tech?
[18:44:29] <zeeshan|2> the best possible kind
[18:44:37] <Tom_itx> zeeshan|2 probably depends on the tip size they're using
[18:44:38] <zeeshan|2> can you deposite 0.0001"?
[18:44:41] <zeeshan|2> thin
[18:44:45] <Tom_itx> most use .5mm i think
[18:44:48] <Tom_itx> i doubt it

[18:44:59] <zeeshan|2> what do you call em
[18:45:02] <zeeshan|2> FDM.. i think
[18:45:09] <zeeshan|2> im talking about the ones that use powder
[18:45:20] <CaptHindsight> nanometers
[18:45:24] <Tom_itx> yeah those are more precise
[18:45:29] <zeeshan|2> the MEMS shop has a 3d printer
[18:45:34] <zeeshan|2> i was wondering if i could place my sample
[18:45:35] <Tom_itx> not for your average hobbyist
[18:45:36] <ssi> SLA layer thicknesses are typically .002 to .006"
[18:45:38] <zeeshan|2> and 3d print a specle pattern
[18:45:45] <zeeshan|2> thats 0.0001" thick
[18:45:48] <zeeshan|2> or less
[18:46:04] <CaptHindsight> so ~2.5 micron
[18:46:06] <zeeshan|2> am i going crazy or is this something possible?
[18:46:13] <Tom_itx> not going...
[18:46:18] <zeeshan|2> haha
[18:46:20] <Tom_itx> :)
[18:46:53] <Rab> Sounds like 2D printing.
[18:47:08] <CaptHindsight> zeeshan|2: whats the material?
[18:47:12] <zeeshan|2> another polymer
[18:47:23] <CaptHindsight> in what form? liquid?
[18:47:29] <zeeshan|2> no
[18:47:36] <zeeshan|2> its that smp laminate
[18:47:49] <zeeshan|2> the smp is 0.008" thick
[18:48:00] <zeeshan|2> i want a very thin layer put on it
[18:48:02] <zeeshan|2> of dots
[18:48:07] <zeeshan|2> using a 3d printer
[18:48:15] <zeeshan|2> if the mems guys can print gears that are nanometers
[18:48:18] <CaptHindsight> what do the dots need to be made of?
[18:48:20] <zeeshan|2> i dont see why i cant use the same technique?
[18:48:30] <zeeshan|2> CaptHindsight: it doesnt matter as long as they adhere to the smp

[18:50:04] <zeeshan|2> no
[18:50:09] <zeeshan|2> like 0.001" is okay
[18:50:09] <CaptHindsight> something visible to the naked eye?
[18:50:15] <CaptHindsight> inkjet
[18:50:17] <zeeshan|2> which is 0.0254 mm
[18:51:26] <CaptHindsight> you can also spin coat with a photopolymer and cure with a laser
[18:51:58] <CaptHindsight> then rinse off the uncured photopolymer
[18:52:07] <pcw_home> or just contact print
[18:52:15] <zeeshan|2> its gotta be a speckle
[18:52:20] <zeeshan|2> i think spin coating isnt randomized?
[18:52:35] <zeeshan|2> im trying to make use of what we have
[18:52:42] <CaptHindsight> the curing randomizes the pattern
[18:52:48] <CaptHindsight> ugh
[18:53:07] <CaptHindsight> now you're starting to sound like Jymmm :)
[18:53:21] <pcw_home> spin coat is just to apply a uniform layer of photopolymer
[18:53:33] <zeeshan|2> CaptHindsight: my understanding is the 3d printers in the mems lab
[18:53:33] <CaptHindsight> simple question that ends up having 487,348 conditions
[18:53:49] <zeeshan|2> prints in layers.. and they make gears as small ias 0.00001" in diameter
[18:53:55] <zeeshan|2> some things even in nanometers
[18:54:18] <zeeshan|2> i want to know what kind of technology tha tis
[18:54:23] <zeeshan|2> cause i have 0 idea about 3d printing.
[18:54:34] <CaptHindsight> mems are silicon
[18:55:12] <CaptHindsight> they might have a 2-photon setup there to print using photopolymers

[19:00:05] <CaptHindsight> speckle photo
[19:00:33] <pcw_home> make artwork, photoplot mask at 4000 DPI or so apply colored photopolymer to substrate, lay photomask over substrate, expose to UV, develop
[19:01:26] <CaptHindsight> spin coat a photosensitive emulsion to the ~2.5um
[19:01:36] <pcw_home> (should be no more than a few 10s of dollars to get a 8x10 photoplot)

[19:09:33] <CaptHindsight> UV nail acrylic probably has a PI sensitive up to ~380nm
[19:10:19] <CaptHindsight> difficult to spin coat since the viscosity is so high
[19:10:28] <Rab> Thin with acetone?
[19:10:34] <zeeshan|2> when i have a photomask
[19:10:37] <zeeshan|2> i lay it on my sample
[19:10:41] <zeeshan|2> and expose it to uv light?
[19:10:47] <zeeshan|2> and the crap transfers over?
[19:10:48] <CaptHindsight> acetone is not an active solvent
[19:10:53] <pcw_home> you "paint" the entire sample with the (white?) photopolymer
[19:10:55] <pcw_home> then expose to UV through the mask
[19:10:56] <pcw_home> the develop (wash with solvent) "paint" washes away where it was not exposed to UV
[19:11:09] <zeeshan|2> thats the hard part
[19:11:12] <zeeshan|2> how do you paint it evenly?
[19:11:16] <Tom_itx> sounds like what i did with my silkscreen
[19:11:25] <zeeshan|2> do you just squish it with a squeegee
[19:11:33] <CaptHindsight> zeeshan|2: remember I offered to send you some visible light cure photopolymer
[19:11:35] <zeeshan|2> and remove the excess w/ the photomask
[19:11:41] <zeeshan|2> CaptHindsight: yes you did
[19:11:52] <pcw_home> spray or spincoat
[19:11:54] <CaptHindsight> you will need to spin coat it to get the 2.5um layer
[19:12:06] <zeeshan|2> okay so i need to see if i have a spincoater
[19:12:15] <CaptHindsight> you can make one
[19:12:15] <zeeshan|2> obv this has to be done in a dark room..
[19:12:20] -!- chillly has quit [Quit: Ex-Chat]
[19:12:25] <zeeshan|2> i think we have one in the corossion lab
[19:12:26] <zeeshan|2> i need to look
[19:12:27] <CaptHindsight> no, just in dim room
[19:12:48] <zeeshan|2> spin coat sample -> layer photomask over -> visible light cure
[19:12:51] <CaptHindsight> sanding pad attachment for drill
[19:12:57] <zeeshan|2> how do you clean the photomask after
[19:13:01] <zeeshan|2> water?
[19:13:09] <CaptHindsight> rinse with ethanol or IPA
[19:13:20] <zeeshan|2> okay this looks REALLY like an awesome idea.
[19:13:29] <pcw_home> you should not need to clean it
[19:13:30] <zeeshan|2> if its visible light i highly think it will work
[19:13:37] <zeeshan|2> uv light might cause problems
[19:13:41] <zeeshan|2> it might cake the polymer
[19:13:49] <pcw_home> its applied only to "dry paint"
[19:13:51] <zeeshan|2> or kill some of the copolymers
[19:14:05] * Tom_itx waits for the big brown truck
[19:14:07] <CaptHindsight> I think he meant rinse off the uncured photopolymer
[19:14:13] <zeeshan|2> uncured polymer yes
[19:14:21] <zeeshan|2> from my photomask so i can reuse it
[19:14:36] <CaptHindsight> no, from the sample part
[19:14:39] <pcw_home> its not applied to the mask
[19:14:49] <zeeshan|2> one side of the mask will be touching the photopolymer though?
[19:14:50] <pcw_home> the mask stays clean
[19:15:06] <CaptHindsight> the photopolymer is applied to the sample part, and then spin coated
[19:15:13] <zeeshan|2> sample <> photopolymer <> mask
[19:15:19] <pcw_home> at that point the photopolymer is dry
[19:15:23] <zeeshan|2> oh.
[19:15:32] <zeeshan|2> that makes sense
[19:15:35] <pcw_home> spin coated --> dried
[19:15:51] <pcw_home> looks just like paint
[19:16:00] <CaptHindsight> pcw_home: is thinking of the water based photopolymer emulsions that dry
[19:16:08] <zeeshan|2> after you do exposure, can you use something not as harsh as alcohol
[19:16:22] <zeeshan|2> to clean off the excess
[19:16:23] <pcw_home> no thinking of KPR type
[19:17:13] <CaptHindsight> water based photoresist
[19:17:24] <zeeshan|2> CaptHindsight: send me some! :)

[19:18:24] <zeeshan|2> i like the idea of photopoylmer
[19:18:31] <zeeshan|2> because likely there will be good bonding
[19:18:36] * zeeshan|2 is no chemist
[19:18:57] <zeeshan|2> whatever, ill try alcohol
[19:19:05] <zeeshan|2> tensile test the sample to ensure it didnt effect the properties
[19:19:11] <CaptHindsight> better than gelatin since it's not a porous substrate
[19:19:12] <zeeshan|2> won't know till i try
[19:19:24] <zeeshan|2> how strong is the bond? :)
[19:19:30] <zeeshan|2> can you scratch it off w/ a finger nail
[19:19:53] <zeeshan|2> googling says photoresists have a strong adhesion to metal
[19:19:56] <zeeshan|2> but nothing about polymers
[19:20:12] <CaptHindsight> depends on the oligomers and monomers used, whats the sample made with again?

[19:21:27] <zeeshan|2> to try out
[19:21:41] <zeeshan|2> ill order a photomask
[19:21:50] <zeeshan|2> find a spin coater and uv light
[19:21:52] <zeeshan|2> and try this out
[19:22:03] <zeeshan|2> this will help a lot w/ 3d aramis optical measurement
[19:22:29] <CaptHindsight> zeeshan|2: how important is layer thickness?
[19:22:39] <CaptHindsight> whats the range?
[19:22:51] <zeeshan|2> if my sample thickness is say 0.008" , and my film thickness is 0.001"
[19:22:57] <zeeshan|2> then likely it will effect the mechanical propeties
[19:23:05] <zeeshan|2> thats why i want it to be 0.0001" min
[19:23:20] <zeeshan|2> film thickness = photpolymer thickness i mean
[19:23:42] <CaptHindsight> so whats the min max?
[19:24:09] <zeeshan|2> less than 0.0001" (0.0025mm)
[19:24:18] <pcw_home> I wonder if it will be difficult to make the photopolymer opaque enough at those thicknesses
[19:24:27] <CaptHindsight> what color?

[19:27:30] <zeeshan|2> even if it was orange
[19:27:31] <zeeshan|2> it might work
[19:27:36] <zeeshan|2> as long as it contrasts the black

[19:58:27] <CaptHindsight> Jymmm: black colorants cab be tough to source based on the application, even carbon blacks vary from grey, to brown to blue

[19:58:57] <witnit_> reupload to the server for us

[19:59:25] <Jymmm> CaptHindsight: Yeah, they do a great job making it appear black, but when you look up close or in certain light the true" color is reveiled
[19:59:28] <CaptHindsight> Jymmm: it might be lower cost to use lots of purple dye vs a black

[20:00:54] <malcom2073> witnit_: linuxcnc code makes my head hurt :( I'm not that good
[20:00:58] <CaptHindsight> Jymmm: for example BASF makes a black dye that is really black for $80/lb and you have to buy ~200/lbs at a time min
[20:01:41] <Jymmm> CaptHindsight: ouch. I'll have to look at Rit Black dye sometime and see what they do out of curiosity
[20:01:49] <CaptHindsight> Jymmm: a purple or brown might be $10/lb and you just use $40/per ton of whatever you make
[20:02:22] <CaptHindsight> Jymmm: fabric dyes are whole other thing
[20:02:32] <robin_sz> anodising dyes?
[20:02:33] <Jymmm> CaptHindsight: Yeah, I just dont think there is a "practical" black dye, where deep purple/blue will do just fine instead.
[20:03:14] <CaptHindsight> carbon blacks are $1/lb and up but they are pigments vs dye
[20:03:24] <Jymmm> CaptHindsight: or heck, it might just be easier to use RBY dye mixed together to get "black" instead
[20:03:31] <CaptHindsight> dyes are in solution where pigments are in suspension
[20:04:11] <robin_sz> I was thinking of buying an anodising thing
[20:05:30] <robin_sz> http://www.rileysurfaceworld.co.uk/machines/25877.htm
[20:05:45] <CaptHindsight> anodizing dyes are water based, a nice trick is to use solvent based dyes in an ethanol bath, spray or print for really deep colors
[20:06:39] <CaptHindsight> you can wait longer between anodize to coloring and it doesn't wash out when sealing
[20:07:22] <Jymmm> CaptHindsight: still uniform when evaporating?
[20:07:30] <CaptHindsight> yes
[20:07:33] <Jymmm> cool
[20:07:46] <CaptHindsight> the dye stays behind in the pore

[20:07:58] <CaptHindsight> the ethanol evaporates
[20:08:07] <Jymmm> ah
[20:09:05] <CaptHindsight> you can combine the solvent based dying with water based dying since they won't mix, to get those splash effects
[20:09:34] <CaptHindsight> you can even inkjet using solvent dye before sealing
[20:09:50] <Jymmm> Wat, I thught ethanol was somewhat alochol based, as alcohol is water soluable.
[20:10:19] <CaptHindsight> yes, the ethanol is but the dye isn't
[20:10:24] <Jymmm> ah
[20:16:01] <CaptHindsight> Jymmm: Kiwi shoe dye is solvent based, it works in anodize
[20:16:23] <Jymmm> CaptHindsight: heh
[20:18:28] <CaptHindsight> Fiebings leather dye is another
[20:19:34] <Rab> Rit dye is another brand people use quite a bit.
[20:20:00] <CaptHindsight> rit for fabric is water based
[20:20:13] <Jymmm> Rab: Rit is water based though, not solvent
[20:20:35] <CaptHindsight> it works but it's expensive and difficult to end up with saturated colors
[20:20:43] <Jymmm> Rab: But some are making it alcohol based for unique applications
[20:20:50] <PetefromTn_> I really need to get an anodization station put together here.. with all the billet aluminum parts I machine it is a no brainer really just have not gotten that far yet.
[20:21:24] <CaptHindsight> water based dye bath is art as much as science
[20:21:33] <JT-Shop> mine is only needed start up time
[20:21:34] <Rab> Hmm, it's the brand I always hear about for home anodizing...maybe that's just because it's easy to grab at the supermarket.
[20:22:01] <CaptHindsight> anodizers figure out just the right timing, temps and ph
[20:22:03] <Jymmm> Rab: Rit even has pantone color swatches
[20:23:13] <CaptHindsight> you can also use pigment but the pigment has to be milled down to a few nm to fit into the pores

[21:07:24] <alex____w> do you have a servo or stepper machine?
[21:07:28] <cncej> servo
[21:08:00] <alex____w> clicking that field in pncconf is the easy answer
[21:08:03] <witnit_> are you talking about the way it appears on the screen?
[21:08:15] <cncej> the way it appears on the screen
[21:08:17] <witnit_> within the black drawing box?
[21:08:25] <witnit_> yeah that wold related to the kinimatics
[21:08:27] <cncej> yes, the backplotter
[21:08:44] <witnit_> so you are talking more about the GUI
[21:09:17] <alex____w> why would you want to reverse the picture without reversing your machine?
[21:09:21] <witnit_> I think you would have to rework more than just the INI
[21:09:22] <alex____w> are the coordinates correct on the machine?'
[21:09:33] <cncej> the machine now moves according to the keyboard so that the table/tool moves to the directions of the arrows printed in the keyboard. My problem is that the axis GUI displays the Y axis to the opposite direction and the "-" sign doesn't work in the .ini file
[21:09:53] <cncej> the Y is inverted
[21:10:19] <alex____w> your servo is turning backwards from what linuxcnc things, flip the encoder and motor direction in pncconf
[21:10:24] <alex____w> try that first

[21:12:04] <witnit_> so is reminding people hahahah
[21:12:11] <alex____w> and put all of our customization in other hal files
[21:12:25] <cncej> I'd guess change the input_scale polarity as well as PID polarity
[21:12:39] <alex____w> sounds about right
[21:12:40] <cncej> I'll try that.
[21:13:10] <cncej> my machine is custom firmware for mesa 7i43. 6 PWM & encoder channels, few IO to each driver (VSD-E) and 2x serial as expansion

[21:17:08] <zeeshan|2> is pncconf working well?
[21:17:12] <zeeshan|2> i will need to soon use it :P
[21:17:32] <alex____w> yes, it's working pretty well these days
[21:17:52] <JT-Shop> I've never used it
[21:18:01] <zeeshan|2> JT-Shop: you're hardcore though
[21:18:11] <JT-Shop> not really
[21:18:24] <alex____w> i'm not normally a gui person, but it's nice for basic configuration of the servos
[21:18:32] <alex____w> and using the open loop test to make sure directions are right, etc
[21:18:37] <zeeshan|2> when i used stepconf
[21:18:39] <zeeshan|2> it helped a lot.
[21:18:47] <zeeshan|2> to setup the skeleton of hal
[21:19:28] <alex____w> and there are enough other hal files loaded which aren't touched by pncconf/stepconf to customize without breaking the ability for pncconf to be run again later
[21:19:51] <alex____w> the main machines that i work on are used/owned by machinists, not programmers, so it's better to keep pncconf functional
[21:19:51] <cncej> ok, I inverted the input_scale and PID. now AXIS displays the geometry ok, but the table moves to the opposite direction (I'd like it so, that the table moves to the same direction that the arrow key on keyboard)
[21:20:00] <JT-Shop> I find it is easier to maintain if you start with a sample config
[21:20:04] <alex____w> cncej: you really don't want it to move that way
[21:20:20] <alex____w> that is the opposite of how the cutting head is moving against the object
[21:20:47] <JT-Shop> cncej, do you know the correct direction of movement for +- on each axis
[21:21:00] <JT-Shop> it is the tool movement that counts not the table
[21:21:31] <alex____w> JT-Shop: the resulting configs from pncconf/stepconf are well enough commented that it is basically like starting with a sample config
[21:21:37] <alex____w> just one that already works for your machine
[21:21:45] <alex____w> i should stop saying stepconf, since i haven't used that in a year

[23:36:02] <JT-Shop> damn I trashed my parting tool holder
[23:37:42] <JT-Shop> I need one that can take the side load of pulling the delrin through the collet
[23:39:03] -!- karavanjo has quit [Ping timeout: 264 seconds]
[23:39:28] <furrywolf> side loading is pretty much exactly what parting tools aren't used for.

[23:45:08] <zeeshan|2> hm
[23:46:00] <zeeshan|2> when i measure @ the motor termins resistance betwene u1 and u2 , or u1&v1, or u1&w1, or u1&v2 or u1&w2 , i get conitnuity.
[23:46:07] <zeeshan|2> and read 2 ohms
[23:46:12] <zeeshan|2> terminals
[23:46:35] <furrywolf> 2-speed y-wired motor?
[23:46:45] <zeeshan|2> i dunno it says D or YY.
[23:46:54] <zeeshan|2> on the name plate
[23:47:06] <furrywolf> I've done very little 3ph work, unfortunately.
[23:47:15] <zeeshan|2> i wish this damn motor had a wiring diagram
[23:47:17] <zeeshan|2> like all the others.
[23:48:58] <furrywolf> usually I'd figure you just either jumper three of them together for wye, or jumper three pairs together for delta... never seen a motor with all six hooked up individually.
[23:49:56] <zeeshan|2> yea man
[23:49:57] <furrywolf> or is this just a single-phase motor with confusing terminals?
[23:49:57] <zeeshan|2> lol
[23:50:03] <zeeshan|2> no its 3 ph

[23:51:19] <furrywolf> 1630 3280 min-1 sure sounds like a 2-speed motor.
[23:51:24] <zeeshan|2> i literally see u1 u2 v1 v2 w1 w2
[23:51:35] <zeeshan|2> on the terminal block in the motor thing
[23:51:38] <furrywolf> the delta/yy marking sounds very 3ph-ish.
[23:52:05] <zeeshan|2> yea
[23:52:07] -!- patrickarlt has quit [Quit: Leaving...]
[23:52:16] <furrywolf> try connecting 3ph to u1 v1 w1, then do the same to the 2s.
[23:53:14] <_methods> http://www.congatec.com/en/products/mini-itx/conga-ic97.html
[23:53:51] <zeeshan|2> whats throwing me off.
[23:53:59] <zeeshan|2> is the contunity between u1 and all the other pins
[23:54:03] <zeeshan|2> its like tehre is a short circuit?
[23:54:06] <zeeshan|2> its only measuring 2 ohms.

[23:54:23] <furrywolf> random forum post says:
[23:54:24] <furrywolf> The connections for a two speed, six wire IEC motor are...I believe
[23:54:24] <furrywolf> Low speed= line connections on 1U, 1V and 1W with the remaining wires open (not connected to each other)
[23:54:24] <furrywolf> High speed= line connections on 2W, 2U and 2V with the remaining wires joined together and taped.
[23:54:24] <furrywolf> If you do a Google search for EASA Handbook you will find all this information..good luck
[23:54:46] <furrywolf> stopped motors are always short circuits.
[23:55:15] <furrywolf> that's why they draw hundreds of amps until they spin up. :)
[23:56:53] <zeeshan|2> haha
[23:56:58] <zeeshan|2> i thought itd be a bit more
[23:57:10] <zeeshan|2> http://www.hollandindustrial.com/PDF%20Files/Identify%20Unmarked%20Leads%206%20and%209%20Lead%20Motors.pdf
[23:57:13] <zeeshan|2> reading that :)
[23:57:23] <zeeshan|2> but what youre saying makes a lot of sense.
[23:57:27] <zeeshan|2> 2 speed motor.
[23:57:46] <zeeshan|2> so it draws 3.6kW in 1 speed?
[23:57:50] <zeeshan|2> and 4.4kW in the other?
[23:57:54] <furrywolf> the two complete sets of ratings rather suggests 2-speed. heh.
[23:57:55] <zeeshan|2> thats a bit weird :P
[23:57:55] <furrywolf> yes
[23:58:07] <furrywolf> why is it weird that it uses less power when running slower?
[23:58:42] <zeeshan|2> i duno single phase motors usually are 1 hp
[23:58:52] <zeeshan|2> i dunno :)
