[00:22:41] <RyanS> I had kind of a tailstock camlock crappy design..... :( cam section starting to bend after second use
[00:23:55] <RyanS> There is some website called "nothing too strong ever broke" I usually abide by that
[00:57:33] <toastyde2th> RyanS, why would you use a camlock for a tailstock
[01:20:12] <RyanS> It seems to be a common and easier method instead of a shiftinng spanner/nut
[01:22:30] <toastyde2th> common where
[01:22:47] <toastyde2th> ain't no production lathe I know of that uses a camlock for the actual tailstock bar
[01:23:06] <toastyde2th> there's lots of camlocks on tailstock carriages and split nut locks, though
[01:23:36] <RyanS> Sorry I was referring to the carriage itself
[01:29:17] <RyanS> I'm about to open up my three-phase motor.. It has no badge, but is it easy to identify 2, 4, 6 pole?
[01:33:03] <toastyde2th> no idea
[02:05:29] <Deejay> moin
[02:19:20] <Loetmichel> mornin'
[02:33:44] <archivist> RyanS, number of slots relates to poles
[02:34:24] <archivist> and the method of pole interconnection, see a motor book
[02:35:16] <archivist> but the rewire to delta is not too hard as there is only one star connection
[02:48:05] <Jymmm> archivist: Do you have any suggestions on how to setup resist/electro-etching to create a few of these "tiles" from a larger sheet of material ?
http://i40.tinypic.com/160aolf.jpg
[02:48:52] <Jymmm> archivist: The "tiles" might just drop out of the larger sheet before they've had a chance to etch out the honeycomb pattern.
[02:50:00] <Jymmm> archivist: The only thing I can think of is an inside-out process, but seems a tad process intensive.
[02:52:50] <archivist> leave a joining tag
[02:53:10] <Jymmm> oooohhhhh good idea!!!!! THANK YOU =)
[02:54:12] <Jymmm> Know of any good press-type tool to shearing the tab(s)?
[02:54:29] <archivist> scissors
[02:55:06] <Jymmm> My luck, I'd leave a razor sharp edge =)
[02:55:44] <Jymmm> I don't mind creating a fixture to have clean cuts
[02:55:49] <archivist> clean up any edges left
[02:56:30] <archivist> all cutting methods leave sharp edges
[02:56:54] <Jymmm> I was thinking of something like this, but squared, not round dies
http://www.grizzly.com/products/H7862
[02:57:06] <archivist> there are production methods of edge fixing
[02:58:47] <archivist> barrel polish with the correct abrasive, you get a consistent finish and deburred
[02:59:51] <archivist> that punch is for round holes, leaves an edge around the hole
[02:59:54] <Jymmm> This is 10mil so it has a higher razor potential which I'm hoping the electroetching will resolve, less the tabs
[03:01:08] <Jymmm> I'm just wondering how something like this has to burrs (tumbled?)
http://media.jetpress.com/ovxyuhpl10/Single-Cable-Pipe-Clip-Edge-Fixing-Standard.jpg?width=580&height=580
[03:01:18] <Jymmm> s/to/no/
[03:02:21] <archivist> likely that was punched out to leave burs inside, also tumbled=barrel polish
[03:02:39] <Jymmm> ah
[03:03:25] <archivist> as it has black finish that has been processed after any polish
[03:04:09] <Jymmm> It was just a burr-free "punch" image I found for an example is all.

[05:46:58] <RyanS> http://imagebin.org/280485
[05:56:37] <archivist> do you still have that link I gave yesterday showing a motor wiring being taken apart
[06:00:01] <archivist> http://madmodder.net/index.php?topic=7773.0
[06:02:10] <archivist> you have to undo the string restraining the wire and winding, find the star joint, you now have 6 ends
[06:03:38] <archivist> disconnect the star, and now connect as delta, re tie check for shorts and leaks to frame
[06:05:28] <archivist> reassemble, final check, three windings measure the same and still no leaks to frame, connect to a vfd and bring up slowly
[06:07:03] <archivist> be very careful you dont foul the through bolts when you tie the wires
[06:08:46] <TekniQue> don't they make inverter VFDs nowadays that can run a 400V motor from 230V single phase?
[06:09:04] <archivist> yes, cost about twice as much
[06:09:48] <archivist> there being a double inversion internally
[06:10:01] <TekniQue> aye
[06:10:37] <TekniQue> that being said, 3x63 amps is standard issue nowadays here
[06:10:50] <TekniQue> even in residential housing
[06:12:45] <archivist> rare to get 3 phase to the house I think
[08:15:11] <TekniQue> http://i.imgur.com/4QaTs51.jpg
[08:15:16] <TekniQue> oops, wrong window
[08:31:09] <skunkworks> ouch - curbed
[09:02:29] <pcw_home> skunkworks: 7I76E running under linuxcnc/PreemtRT for about a day now, no major bugs
[09:05:11] <skunkworks> awesome! I have been testing the tp that rob has been working on - so I have not gotten back to trying the new stuff for the 7i80
[09:05:25] <skunkworks> what kind of servo thread time are you getting?
[09:05:51] <pcw_home> I am running a standard1 KHz
[09:06:25] <skunkworks> I meant - how long are the functions taking
[09:06:29] <pcw_home> average time use for comms is about 100 usec
[09:06:54] <skunkworks> oh - nice. (I was seeing around 600 peak here with rtnet)
[09:07:16] <pcw_home> sometimes the RX time is much longer (on this machine video interferes)
[09:07:16] <skunkworks> so 2khz might be possible?
[09:08:42] <pcw_home> On this machine under Preemt RT Video interferes with RX so 1 KHz may be max
[09:08:44] <pcw_home> But I dont think all the possible tweaks have been done
[09:09:41] <pcw_home> (setting Ethernet RX interrupt priority high is one thing suggested by OSADL)
[09:10:34] <skunkworks> you must have figured out the incatation (mac address and such?)
[09:11:42] <pcw_home> Yes:
[09:11:44] <pcw_home> [HOSTMOT2]
[09:11:45] <pcw_home> DRIVER=hm2_eth board_ip="192.168.1.121" board_mac="00:60:1B:10:40:01"
[09:11:47] <pcw_home> BOARD=7i76e
[09:11:48] <pcw_home> CONFIG="num_encoders=1 num_stepgens=5 sserial_port_0=20xxxxxx"
[09:12:17] <pcw_home> But thats it, no other setup magic
[09:13:11] <skunkworks> nice
[09:13:16] <pcw_home> I probably should set the ip address so that it does not overlap my wireless range
[09:13:56] <skunkworks> yah - the ip was also part of our wired network - but didn't seem to cause any problems with rtnet
[09:14:10] <skunkworks> (two separate nics)
[09:14:40] <pcw_home> This is the MB Ethernet port on this old shuttle MB
[09:15:12] <pcw_home> dont even know what it is (thats the advantage of Preemt_RT)
[09:15:19] <skunkworks> awesome. that should really help if 'most' hardware should run now
[09:15:34] <skunkworks> right
[09:16:15] <skunkworks> have you had good luck with shuttles? I think every one we have had now has failed.
[09:16:32] <skunkworks> (they came with some equipment we got)
[09:16:36] <pcw_home> No, they are miserable
[09:16:42] <skunkworks> ok - good. :)
[09:16:43] <FinboySlick> Ditto.
[09:17:05] <FinboySlick> Every shuttle mobo I've come across died.
[09:17:42] <pcw_home> I have this one as its a Frankenstein of the last working remains of a bunch we had at work that all died
[09:17:57] <skunkworks> heh - ok. Atleast it isn't just us.
[09:18:24] <pcw_home> all PS issues (either the PS proper or the switching reg on the MB)
[09:18:44] <skunkworks> yes - we have had a bunch of power supplies with blown caps
[09:18:52] <FinboySlick> part of the capacitor-gate scandal? It was around that time, no?
[09:19:01] <pcw_home> maybe so
[09:20:04] <FinboySlick> Mention of video interfering with RT though... Since Axis is mostly xorg-based, wouldn't there be a good case to be made for easy setup with remote X display and no actual video drivers on the EMC machine?
[09:22:08] <FinboySlick> It was a long time ago, but even then opengl through remote display worked fine.
[09:22:34] <FinboySlick> I failed miserably trying to get that to work with LinuxCNC when I was doing my initial setup though.
[09:22:49] <pcw_home> Sure, for the highest performance you want the fewest possible interfering tasks
[09:22:50] <pcw_home> (heck for the highest performance you want a machine that only runs HAL and has no
[09:22:52] <pcw_home> interrupts: all Ethernet coms are synchronous polled at the thread rate
[09:23:30] <skunkworks> that is close to what the bbb does I think
[09:23:52] <pcw_home> Well no the BBB is a standard linux mess
[09:24:34] <skunkworks> well - I mean most are running remote because it is a bit hard on it running axis
[09:24:57] <skunkworks> (but I have only been paying half attention...
[09:25:00] <skunkworks> )
[09:26:47] <pcw_home> I do think its a good general idea to spilt the user interface from the real time portion
[09:26:49] <pcw_home> so each hardware platform can be optimized for their specific task
[09:26:51] <FinboySlick> Heck, you could even netboot and disable all the drive controller hardware.
[09:27:11] <pcw_home> Yeah
[09:28:49] <pcw_home> I saw some old CNC system mentioned on cnczone that did this with 2 PCs, one for user interface and the other as a DSP
[09:29:03] <pcw_home> 386 vintage
[09:29:08] <FinboySlick> I'm still on Ubuntu 8 based livecd install... Can modern kernels (3.x) be used relatively easily now?
[09:29:46] <FinboySlick> pcw_home: That's what I wanted to do with my ALIX board, but I think it just sucks for RT.
[09:29:54] <pcw_home> Yes its much easier now thanks to Mhaberler and friends
[09:30:32] <FinboySlick> I might give a try at setting up a buildroot package for it.
[09:30:49] <FinboySlick> (buildroot the linux 'distro', not the general build system)
[09:31:07] <pcw_home> well if it suck for RT its really likely theres some process that blocks interrupts and its likely some driver
[09:31:28] <skunkworks> FinboySlick, good starting point
http://wiki.linuxcnc.org/cgi-bin/wiki.pl
[09:31:31] <FinboySlick> pcw_home: It's video related from what I read.
[09:31:47] <FinboySlick> I couldn't even get to a point where I could test the RT kernel.
[09:31:53] <FinboySlick> So I don't know for sure.
[09:32:14] <FinboySlick> I'll give it another shot with a newer kernel.
[09:32:20] <skunkworks> FinboySlick, I think I meant...
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?NewRTInstall
[09:34:42] <FinboySlick> http://buildroot.net/ apparently has built-in xenomai support.
[09:34:45] <pcw_home> Now if sound only worked on the Preempt RT- kernel I would leave it running my desktop
[09:35:12] <skunkworks> latency spikes?
[09:35:38] <pcw_home> No it just doesnt work
[09:35:41] <skunkworks> oh
[09:35:44] <skunkworks> huh
[09:37:31] <mrsun_> gah how to make a touch off plate that wont pass current throught the spindle bearings .. and its hard to get to the tool to clip a contact on that also :/
[09:38:28] <mrsun_> and that is big enough to now having to have to see exactly where the tool is while i touch off :P
[09:38:55] <FinboySlick> mrsun_: Doing the home-made touch probe thing might work better, no? Just put it upside-down with a flat 'probe'.
[09:39:28] <pcw_home> no sound _and_ the fact that is crashes about once a day...
[09:39:58] <mrsun_> FinboySlick, i want the touch of to be automatic as my brushes gives a huge preasure down on the table and everything i stuck under i cant realy feel good when the tool touches it =)
[09:40:23] <mrsun_> with my current router i guess i could just drill a holw in the back end and use a contact directly on the spindle shaft :P
[09:50:41] <MacGalempsy> mornin
[09:54:41] <archivist> FinboySlick, you had wandered off when I saw your message
[09:57:12] <JT-Shop> mrsun_: the best touch off tool is a dowel
[10:03:43] <FinboySlick> archivist: It wasn't all that important. I just wanted an opinion on the best tools to get my linear rails flat and perpendicular (on the machining/grinding side). I think they're recessed so I doubt I could even use a surface grinder.
[10:05:49] <archivist> FinboySlick, or adjust the column mount where it fits the base
[10:06:46] <FinboySlick> http://www.syilamerica.com/product_docs/MachineDocs/X5/x5.pdf pages 34-36
[10:07:09] <FinboySlick> archivist: Just adjusting the mating between column and base isn't enough.
[10:07:23] <FinboySlick> The column seems warped/twisted.
[10:07:35] <FinboySlick> (or the rails aren't even).
[10:09:23] <archivist> you could try shims under the rails to see where it is wrong
[10:10:23] <archivist> basic squareness is probably the base to column for most of the error
[10:11:37] <FinboySlick> What I'm thinking on doing is re-facing the surface on the base where the Y rails are fastened as well as the surface where the column mounts on the same setup. That would at least make those decently parallel.
[10:12:13] <archivist> before cutting/grinding measure
[10:12:32] <FinboySlick> archivist: Good idea ;)
[10:12:49] <FinboySlick> I also need a machine that I can trust to do this.
[10:13:06] <FinboySlick> Obviously, the result would be as reliable as the machine that cut it.
[10:13:13] <archivist> you can do a hell of a lot with the right level...and files
[10:13:54] <archivist> and a few dtis and other assorted measuring toys
[10:14:00] <FinboySlick> archivist: The rail mounts are recessed though. It'd be a lot simpler if I could just lap the whole thing.
[10:14:52] <archivist> I would lift off the table place level on carriages and check
[10:15:11] <archivist> some parallels are needed too
[10:15:56] <archivist> do you have a precision level yet
[10:18:24] <FinboySlick> No.
[10:19:11] <archivist> if the problems are just sloppy assembly, all you need do is get the measuring toys and assemble correctly
[10:20:10] <archivist> here the the clearance around the screws holding the rails to column could be giving you a squareness problem
[10:21:12] <FinboySlick> I seem to be getting most of my errors (on the Y axis) at the ends, so I think there's a banana effect here.
[10:22:08] <archivist> oops you just missed a bible
http://www.ebay.co.uk/itm/Machine-Tool-Reconditioning-by-Edward-F-Connelly-1955-/300892448874
[10:23:28] <FinboySlick> archivist: a good place do do all this in is likely to be the hardest to find for me.
[10:24:00] <archivist> the rails are a bit bent because of the way they are hardened, they rely on the surface to hold them straight
[10:24:39] <FinboySlick> That's a good bit of information to have.
[10:26:05] <archivist> I got that from one of the machine tool shows
[10:26:23] <archivist> seems that book is available
http://www.abebooks.co.uk/servlet/SearchResults?tn=Machine+tool+reconditioning+applications+hand+scraping
[10:26:59] <archivist> although it predates rails, it does have the measuring
[10:27:34] <archivist> you need a box square really
[10:28:45] <FinboySlick> Hehehe, google image isn't helpful on finding what one of those looks like ;)
[10:29:25] <archivist> box level I mean
[10:31:25] <archivist> http://bbs.homeshopmachinist.net/threads/53674-anyone-used-these-levels
[10:31:47] <archivist> apart from the postage I do have a spare
[10:31:55] <FinboySlick> Sheesh, that's a lot cheaper than I thought.
[10:33:30] <archivist> scruffy one 171170058355
[10:34:22] <archivist> looks like it has been polished on a buff
[10:36:42] <FinboySlick> http://www.shars.com/products/view/2476/6quot_x_112quot_x_6quot_Precision_Frame_Spirit_Levels (assuming it lives up to its specs) should give me a pretty good idea of where the problem is at least.
[10:36:48] <archivist> never cheap this seller 330804628067
[10:37:17] <FinboySlick> are these ebay item numbers?
[10:37:19] <archivist> that is cheap for that spec
[10:37:22] <archivist> yes
[10:38:32] <archivist> thing about this type of level is you can check and get the column right after you have got the table done
[10:38:36] <Jymmm> You don't need an actual level, just a straight edge?
[10:38:48] <archivist> er no Jymmm
[10:39:09] <archivist> this is first principles getting it right
[10:39:47] <FinboySlick> archivist: My concern with the level approach is also that they're almost as long as my entire travel for the rails. In fact, on y, they're longer.
[10:39:53] <Jymmm> So a level IS needed? Is so, can't one use a clear hose and colored water?
[10:40:06] <Jymmm> If so*
[10:40:09] <FinboySlick> So I also need a good way of making sure the rails are flat before I can consider the level accurate.
[10:41:36] <archivist> you put parallels in place of table on carriages at the spacing they are in use and try between carriages and between rails, all over
[10:42:09] <FinboySlick> archivist: Oooh, smart!
[10:42:12] <FinboySlick> Hehe.
[10:42:30] <archivist> you can just put the level on the table and see if it remains stable all over before you do anything
[10:42:31] <FinboySlick> archivist: I'm glad I nagged you about this again now ;)
[10:43:03] <archivist> also move the level about on the table see if it is flat
[10:43:17] <FinboySlick> archivist: Yeah. My chief concern for the time being is actually finding a place where I can do that kind of work.
[10:43:34] <FinboySlick> My floors aren't sturdy enough.
[10:43:37] <archivist> note all this is impossible if your machine is on a wooden floor and you are heavy
[10:43:57] <FinboySlick> It's half-impossible then. It's on a wooden floor, but I'm pretty light.
[10:44:24] <archivist> you will get a shock just how still you need to be
[10:44:32] <FinboySlick> Regardless, I'd do this on a concrete, ground floor.
[10:44:59] <FinboySlick> archivist: These floors move from just me breathing.
[10:45:09] <FinboySlick> It's a terrible place for a machine to be to begin with.
[10:45:23] <archivist> you can use a clinometer too
[10:45:23] <FinboySlick> I'm still gathering money to build a proper place.
[10:45:43] <FinboySlick> All this while I was thinking of a large granite surface and a dti.
[10:46:13] <archivist> I saw a slab of granite on a dead cmm over here the other week
[10:55:37] <FinboySlick> cmm?
[10:56:32] <archivist> coodinate measuring machine
[10:56:49] <FinboySlick> Hehe, it feel on it?
[10:57:37] <archivist> 261318218650
[10:58:10] <FinboySlick> Wow... Now there's a slab of granite.
[10:58:36] <archivist> too big for me to get home
[10:59:01] <FinboySlick> I guess that thing would tell me where my machine flaws are.
[10:59:36] <archivist> I thought about bidding and fetching all the motors and control and leaving the seller with a slab problem
[11:02:52] <FinboySlick> It's a beautiful machine... Do they know what's wrong with it?
[11:02:52] <JT-Shop> like I'll be back later for the slab?
[11:03:24] <FinboySlick> JT-Shop: Have them air-mail it ;)
[11:09:45] <archivist> I think that slab weighs more than the estate car
[12:16:49] <IchGuckLive> hi all B)
[12:21:24] <IchGuckLive> storm over UK and north Europ expected to hit this night
[12:22:39] <Deejay> fleurop?
[13:21:41] <MacGalempsy> link to slab pic?
[13:22:51] <MacGalempsy> my nephew is 8 and wants to get into programming. anyone got any suggestions for literature?
[13:24:09] <Jymmm> MacGalempsy: LOGO or Arduino
[13:24:27] <Jymmm> with the arduino, he can see the results
[13:24:27] <archivist> basic
[13:24:50] <FinboySlick> MacGalempsy
http://www.ebay.co.uk/itm/ITP-CMM-Machine-/261318218650
[13:24:53] <Jymmm> archivist: Might as well teach him to set the clock on VCRs =)
[13:25:19] <FinboySlick> Best language to learn nowadays is probably python.
[13:25:53] <archivist> too much magic with oop
[13:26:06] <Jymmm> Arduino sketchs are (technically) java, so it's a start.
[13:26:09] <FinboySlick> archivist: You don't need to use oop with python.
[13:26:27] <FinboySlick> You can write purely functional code.
[13:26:34] <Jymmm> FinboySlick: No need to start teaching bad practises
[13:26:42] <archivist> you need the magic whitespace too
[13:26:55] <Jymmm> Yeah, I think that would be a bigger issue
[13:26:58] <archivist> serious bad practice
[13:27:29] <Jymmm> Ardunio... lots of examples, instant feedback
[13:27:45] <Jymmm> and gets to learn electronics along the way at the same time
[13:28:37] <archivist> rpi has more educational stuff probably
[13:28:37] <Jymmm> MacGalempsy:
http://blog.arduino.cc/category/kids/
[13:29:11] <MacGalempsy> Jymmm: thanks, i'll check that out
[13:29:15] <Jymmm> http://techcrunch.com/2013/11/24/primo/
[13:29:30] <jdh> I thought arduino sketches were c++
[13:29:41] <jdh> though I often can't tell the difference.
[13:30:17] <FinboySlick> MacGalempsy: And if you don't want to listened to the python-prejudiced people:
http://shop.oreilly.com/product/9781593274078.do
[13:31:09] <MacGalempsy> trying to get him started with something that would be usefully for me ;)
[13:37:35] <archivist> there is the lego stuff
[13:37:44] <archivist> and it is xmas
[13:48:25] <MacGalempsy> those are an option
[13:53:09] <jdh> vb dot net
[13:59:24] <WalterN> inserts are so expensive
[14:00:04] <WalterN> http://www.mscdirect.com/product/74161522
[14:01:14] <WalterN> http://www.mscdirect.com/product/05095088
[14:01:23] <WalterN> both of those should fit in the same holder, right?
[14:01:33] <syyl--> ever bought a diamond insert? ;)
[14:01:53] <WalterN> syyl--: linky
[14:04:15] <syyl--> as i am sitting in germany, a link to a supplier here would be a bit useless ;)
[14:04:39] <syyl--> those wpmt inserts should fit in the same holder, yes
[14:04:49] <syyl--> same style and size as it seems
[14:05:02] <WalterN> yeah
[14:05:10] <WalterN> though, is it worth the price difference?
[14:06:22] <WalterN> I'm cutting 4150 steel with it
[14:07:22] <WalterN> what do the grade numbers mean?
[14:07:56] <WalterN> Material Grade C5 (for the Hertel brand)
[14:08:20] <syyl--> you have to look for the specs of the manufacturer
[14:08:23] <syyl--> whats it rated for
[14:08:25] <WalterN> Material Grade Micrograin (for the Cutting Tool Technologies brand)
[14:12:22] <WalterN> bleh, I'm not finding any information on insert grade for hertel
[14:15:17] <Tom_itx> what about Kennametal or Sandvik?
[14:16:19] <WalterN> what about them?
[14:16:36] <Tom_itx> for finding insert grades
[14:17:01] <Tom_itx> http://www.sandvik.coromant.com/en-us/knowledge/general_turning/getting_started/choice_of_insert/insert_grade/pages/default.aspx
[14:18:01] <Tom_itx> http://www.sandvik.coromant.com/en-us/knowledge/milling/grade_information/pages/default.aspx
[14:19:00] <Tom_itx> that one looks fairly complete
[14:33:08] <WalterN> I'm finding less information on cutting tool technologies
[14:33:22] <WalterN> their catalog on their website is from 2009 evidently
[14:33:36] <WalterN> and does not contain the insert I'm looking at
[14:49:10] <WalterN> stupid
[14:50:04] <WalterN> not finding any information on this stuff
[14:50:54] <WalterN> is that what everyone does? buy different inserts and stick with the ones that work best?
[14:53:00] <jdh> gets pricey
[15:12:59] <mrsun_> finaly got the touch off plate to work .. damn that was a hassle just to do that, and now i cannot start stepconf anymore cause it overwrites my changes :/
[15:13:08] <mrsun_> stepconf needs to get smarter =)
[15:13:13] <mrsun_> to diff in the changes or something
[15:14:07] <jdh> add your changes to custom.hal or wtf it is.
[15:17:28] <mrsun_> well some changes has to go into mymill.ini also =)
[15:17:31] <mrsun_> all tho not many
[16:32:56] <Mjolinor> anyone aware of a linuxcnc 3d printer implementation that doesn't use an arduino?
[16:33:34] <Mjolinor> I have mad emyself a hot end and stuck an A axis to push the filament but I am unsure fo hte best way to control filament speed adn temperature
[16:34:23] <cpresser> Mjolinor: that depends on the gcode
[16:34:26] <Mjolinor> I have a PIC reading the temperature adn turnign the heater on and off itself but feel that it would perhaps be better to deliver hte temperature fomr the PIC to the PC over serial and let Linuxcnc decide if it's hot enough or not
[16:34:47] <Mjolinor> but I cant find anyone that has done anyhting similar
[16:35:04] <cpresser> Mjolinor: you could create a userspace-hal-comp to communicate with the pic
[16:35:28] <Mjolinor> hmm, perhaps you could but not I :)
[16:35:44] <cpresser> most 'slicer' programs use custom m-codes for extuder and temperature controol
[16:35:52] <Mjolinor> I am happy enough with assembler all day long but C and higher is not soemthign I can do very well
[16:35:57] <cpresser> Mjolinor: when you are able to program a pic, you can do python :)
[16:36:30] <Mjolinor> Skeinforge seems to be pretty straighforaward but as you say there seem to be lots of custom M codes involved that presumably one can download form some reprap site
[16:37:10] <cpresser> anyway, you need to adapt some of the mcodes
[16:37:23] <Mjolinor> I could write a standalone C binary to look after temperature easily enough
[16:38:14] <Mjolinor> feed rate and temperature don't seem to be too well documented generally unless oyu are using an arduino
[16:38:15] <cpresser> Mjolinor:
http://pastebin.com/xZTnQ5Jp thats how i send data to a pic
[16:38:41] <cpresser> Mjolinor: i would take a look at
http://slic3r.org/ its not as complicated as skeinforge
[16:38:58] <Mjolinor> cheers
[16:39:37] <Mjolinor> I find skeinforge OK but it is the only one I have looked at
[16:39:56] <Mjolinor> python bakees my noodle
[16:40:38] <cpresser> that code looks ugly, it was my first python script
[16:40:44] <cpresser> but it works :)
[16:41:37] <Mjolinor> it doesnt look ugly to me, it just looks random :)
[16:41:46] <cpresser> it has everything you need: open, read and write a serial port
[16:42:14] <Jymmm> serial port? who uses serial ports?
[16:42:22] <Mjolinor> I have C programmes that will read serial and I2C already
[16:42:32] <Mjolinor> http://81.110.238.61/
[16:42:44] <cpresser> Jymmm: virtual-serial-ports. for all kind of microprocessor applications
[16:42:44] <Mjolinor> that is using C to talk to some pics over 433 MHz radio
[16:43:05] <cpresser> Mjolinor: you can write a comp in C. its not limited to pyhton
[16:43:28] <Mjolinor> I am just not sure iof linux needs any more than "temperature OK2 or not
[16:44:12] <Mjolinor> given the choice I would do it all in assembler but that would be a lifes work I fear :)
[16:48:48] <Mjolinor> http://linuxcnc.org/docs/html/hal/comp.html
[16:48:54] <Mjolinor> is that where I shoudl start?
[16:49:31] <Mjolinor> seems like a terribly complex place to start, doesnt make a lot of sense to me :)
[16:49:35] <cpresser> Mjolinor: yes, that would do.
[16:49:37] <andypugh> For writing components, yes.
[16:49:57] <cpresser> there should be some examples for userspace components
[16:49:58] <Mjolinor> OK, cheers Ill go read it then :)
[16:50:59] <Mjolinor> I am sort of surprised that no one has done this for a 3d printer
[16:51:38] * cpresser was to lazy to finish the project. i still have the extruder and a partially finished temperature control hidden in abox
[16:52:23] <Mjolinor> :)
[16:52:45] <Mjolinor> I actually bought a 3d printer off ebay
[16:53:02] <Mjolinor> TNT reduced ti to a fair sized pile of recycling before I go tmy hand on it
[16:54:39] <Jymmm> Does anyone have any recommendations for a .22lr pistol?
[16:55:36] <Mjolinor> so you ahve obviously looked t this hot end filament assembly thing then
[16:56:20] <Mjolinor> I was planning on putting hte stepper on a pivot wiht a strong spring and hall effect sensor so that I can read how hard the filament is being pushed
[16:56:21] <cpresser> Mjolinor: i did
[16:56:42] <Mjolinor> but none of the things I have looked at seem to care how hard hte filament is pushed, they jsut push it
[16:57:06] <cpresser> Mjolinor: true. all designs i know dont care about a 'readback'. they just push
[16:57:17] <Mjolinor> so if you push at a particular rate then it is only the temperature that controls how much flows
[16:57:30] <Tom_itx> Jymmm why so small?
[16:58:25] <Mjolinor> thats not right, they dont push, they pass
[16:58:58] <Mjolinor> the amount of push is not used they jsut feed so extrusion rate is fixed and if the hot end is not hot enough then presumably they stall the stepper
[16:59:13] <Mjolinor> or strip the filament
[16:59:47] <cpresser> you just described one of the various problems of FDM-Type printers :)
[16:59:57] <Mjolinor> that doesn't seem sensible to me, much better to measure the force on the filament I think
[17:00:00] <cpresser> i have a seen a lot of people struggling with this issue
[17:00:40] <Tom_itx> Jymmm,

[17:01:04] <Tom_itx> http://en.wikipedia.org/wiki/.221_Remington_Fireball
[17:04:18] <Mjolinor> anyone know what sort of feed in rate the filament needs?
[17:04:37] <Mjolinor> all fo the info I find is realted to output flow rate, nothign about the in rate of the filament
[18:20:23] <Jymmm> Tom_itx: Avaiability of ammo
[18:22:04] <Jymmm> Tom_itx: When I ht the range, I usually go thru 100+ rounds of 9mm and that's now expensive and hard to come by out here
[18:22:32] <Jymmm> Tom_itx: a box of .38 is $42 now.
[18:23:13] <Jymmm> Tom_itx: and that's not even the really good stuff either.
[18:25:07] <Jymmm> Tom_itx: maybe a 10/22 Takedown
[18:25:53] <Jymmm> Tom_itx: I'd rather have a register pistol that I can add a long barrel to though.
[19:21:44] <Tom_itx> Jymmm time to start reloading
[20:00:27] <jdh> what kind of .22 pistol?
[20:00:55] <jdh> I can find plenty of 9mm ammo here. No .22lr though
[20:34:26] <MacGalempsy> 100 rnd box of .40 cal was $$30 at wallyworld (if I remember right)
[20:35:13] <jdh> $40ish for a 100 pack of cheapo stuff
[20:37:33] <Tom_itx> nobody reloads anymore?
[20:37:53] <jdh> sure, but not .22
[20:38:03] <Tom_itx> not sure you can reload those
[21:21:05] <MacGalempsy_> my neighbor reloaded them and said they were ok
[21:26:37] <jdh> you can't 'reload' .22
[21:33:52] <skunkworks> neighbor reloads almost every day
[21:34:13] <skunkworks> He targetshoots and goes through hundreds of rounds every day
[21:34:27] <skunkworks> (ok - couple times a week...)
[21:41:53] <Tom_itx> used to but i haven't done any in a long time
[22:07:33] <Jymmm> I dont think I've seen a wallyword in Calif sell ammo
[22:20:53] <jdh> 25 will be sufficiently hard for me.
[22:21:29] <Tom_itx> shotgun but maybe not rifle
[22:22:07] <jdh> they keep shotgun ammo on the shelves. Everything else is in locked cabinets.
[22:45:26] <ChuangTzu_> there are walmarts in california that sell ammo
[22:45:29] <ChuangTzu_> the one in duarte for example
[22:45:36] <ChuangTzu_> they sell every kind of ammo
[22:46:05] <ChuangTzu_> probably all of them inland too
