[00:47:41] <tjtr33> JT-Shop, i replaced the pyvcp pin with a python file read. and use #5399 as the I term of a G02.
[00:47:50] <tjtr33> When i load it, i get errors saying circle of 0 radius. (true it has no value yet )
[00:47:56] <tjtr33> but i can ignore the error dialog and continue ok.
[00:47:57] <tjtr33> https://videobin.org/+87z/b0v.html
[00:49:19] <tjtr33> not sure why G02 X0Y0I0J0 is illegal ( maybe stupid, but not illegal )
[00:49:54] <tjtr33> illegal/complained about
[01:48:10] <_methods> that will fail every time
[01:48:36] <_methods> well it should
[01:48:53] <_methods> a circle of 0
[01:49:23] <_methods> if you have something in the tool offset page it may do something
[02:04:44] <Deejay> moin
[02:55:07] <Loetmichel> *Huff* *COUGH* mornin' re from the bakery. there WERE times when i had a lot more stammina. 2km bicycling to the bakery and back and i am absolutely out of breath... :-(
[04:25:03] <_abc_> Hello. Can someone please recommend an end mill or burr mill to cut Teflon with? I need a smooth finish, turns out it is tricky. Burr mills do not leave a smooth finish even after 3-4 passes. How does one polish teflon anyway? I tried very fine abrasive paper, does not work.
[04:30:14] <syyl_> have fun :D
[04:30:36] <syyl_> polished single flute endmills are the way to go
[04:31:10] <syyl_> the endmill equivalent of a razorblade...
[04:47:22] <_abc_> I only have 2 fluted end mills but I could grind one off of grind my own single tooth/blade cutter. I do that a lot, did a funny half ball shape yesterday too.
[04:47:33] <_abc_> Do you have a picture please syyl_ ? Link?
[04:47:38] <syyl_> a sharp two flute will work too :D
[04:47:56] <syyl_> http://www.datron.com/images/accessories/High_Speed_End_Mills/End_Mill_Single_Flute_Sprecially_Balanced.jpg
[04:47:56] <_abc_> syyl_: I use the 3d tool grinder all the time eh. It will be sharp.
[04:48:26] <_abc_> Are there any special burr type end mills which create a smooth wall finish?
[04:48:52] <syyl_> thats off my knowledge :)
[04:48:58] <_abc_> Ok, thanks.
[04:48:59] <syyl_> dont use burrs very much
[04:49:17] <_abc_> Burrs are usually easy to come by and do well for roughing jobs
[04:49:32] <syyl_> i use those only in a die grinder
[04:49:36] <_abc_> I am trying to use a single tool to make a trench cut about 2mm wide, 13 deep and 25 long
[04:50:00] <syyl_> ah that small of a slot
[04:50:06] <_abc_> Yes.
[04:50:08] <syyl_> try those pcb endmills
[04:50:19] <_abc_> And I have a 2mm burr which would do it but the surface will not be smooth.
[04:50:21] <syyl_> with the 1/8" shank
[04:50:35] <_abc_> That's what the burr has too. PCB end mills are not nice for this.
[04:50:37] <_abc_> I tried.
[04:50:50] <_abc_> Also they do not reach 13 deep
[04:50:59] <syyl_> relief the shank
[04:51:13] <syyl_> :)
[04:51:17] <_abc_> It breaks off easily. It's carbide 100%
[04:51:19] <syyl_> we do that all the time
[04:51:32] <_abc_> You can't have a thin finger 15mm long and way too thin and load it laterally
[04:51:37] <syyl_> not
[04:51:38] <syyl_> ?
[04:51:44] <syyl_> https://dl.dropboxusercontent.com/u/24396704/QMTL2/IMAG0589.jpg
[04:51:46] <_abc_> You need some martensitic core to take the lateral forces
[04:51:48] <syyl_> 1mm diameter, 30mm long
[04:51:58] <syyl_> dont tell me about long, skinny endmills :D
[04:52:10] <_abc_> Yes, but do you mill a wall with it?
[04:52:23] <_abc_> You know side force, beding, undercut, higher force -> snap
[04:52:35] <syyl_> all the time
[04:52:37] <syyl_> in fact
[04:52:37] <_abc_> *bending
[04:52:42] <_abc_> Hm ok
[04:52:42] <syyl_> carbide can be pretty flexible
[04:52:43] <syyl_> https://dl.dropboxusercontent.com/u/24396704/QMTL2/IMAG0568.jpg
[04:52:48] <syyl_> 0.6x20mm
[04:53:01] <syyl_> solid carbide
[04:53:03] <_abc_> Ok, nice.
[04:53:22] <_abc_> Looks like I will grind one to relieve the cutter and try it
[04:53:23] <archivist> dont take large bites
[04:53:35] <syyl_> of course :D
[04:53:43] <_abc_> Sure, just 0.3-4 mm depth per pass.
[04:53:50] <syyl_> the 1x30mm endmill will take a 7/100mm cut per pass
[04:53:55] <syyl_> of it will deflect
[04:54:01] <syyl_> in plastic
[04:54:02] <_abc_> Yes, well, I need to finish this year
[04:54:16] <_abc_> So I will try to push things a little. And 2mm is more solid anyway
[04:54:17] <syyl_> hey :P
[04:54:20] <syyl_> https://dl.dropboxusercontent.com/u/24396704/QMTL2/IMAG0586.jpg
[04:54:25] <syyl_> i finished this over night
[04:54:36] <_abc_> syyl_: neat.
[04:54:42] <syyl_> finishing pass was with the 1x30
[04:54:47] <syyl_> for reaching down
[04:55:07] <_abc_> What was that part designed in, if I may ask?
[04:55:09] <_abc_> Rhino?
[04:55:19] <syyl_> creo is what we use
[04:55:42] <archivist> note .07mm is way smaller cuts than your .3mm
[04:55:43] <_abc_> Is that hole threaded? Did you thread it manually or?
[04:55:53] <syyl_> na, thats just drilled
[04:56:10] <_abc_> archivist: Yes but teflon does not like very small cutting depths, it deflects and the tool chatters
[04:56:25] <_abc_> archivist: You need a rather special cutter for finishing passes
[04:56:33] <archivist> not sharp enough
[04:56:38] <syyl_> relief yourself a 1,6mm pcb endmill to reach down
[04:56:46] <syyl_> go easy on the roughing
[04:56:55] <syyl_> and finish with a full depth pass
[04:57:14] <_abc_> Yes, I will probbably relieve a 2.5mm one since I already need a 2.5mm tool there and I can use it for another pass too
[04:57:39] <_abc_> That will be solid enough for the job. Nice ideas. Thanks for the tips syyl_ archivist
[04:58:06] <syyl_> :)
[04:58:11] <_abc_> Would you say that a 2.5mm drill bit reground as end mill with flutes relieved would work for this?
[04:58:22] <_abc_> That's one of the things I'll try.
[04:58:27] <syyl_> that would not convince me :D
[04:58:31] <_abc_> Hm?
[04:58:40] <archivist> oh and get a machine as solid as syyl_ is using :)
[04:58:50] <_abc_> Anyway I will program it to plunge repeatedly to clean the chips
[04:58:54] <syyl_> hey, its the cheese master :D
[04:58:57] <_abc_> archivist: Machine is nice and solid ok
[04:59:16] <syyl_> good enough to hog out hard cheese
[04:59:25] <_abc_> Heh.
[04:59:47] <syyl_> plunging out material is a good way for deep slots
[04:59:57] <_abc_> Speaking of, WHERE does one get Delta connectors of various pin counts? The machine has such a Delta and its pin count is unfindable. 50 pins I think, not sure now.
[05:00:08] <syyl_> but i dont think its nessecary for that what you described
[05:00:22] <_abc_> I know it is.
[05:00:38] <_abc_> My own single point cutters are not so terrific at digging out chips
[05:01:01] <_abc_> Also, where does one find a really small diamond wheel for grinders? One with a sharp edge on one side so I can make flutes with?
[05:01:27] <archivist> tell me when you find grinding wheels
[05:01:56] <archivist> I need some wheels for cutter grinding
[05:02:02] <_abc_> archivist: We have grinding wheels here, Chinese and locally made ones, but they are 4 inch. I probably need 2 inch
[05:02:36] <archivist> you can shape your own wheels with a diamond
[05:02:55] <_abc_> These are diamond powder coated alloy wheels.
[05:02:59] <_abc_> So you can't
[05:03:25] <_abc_> I tried normal wheels but they don't even scratch the WC bits we use properly.
[05:06:47] <archivist> I need the wheel shape as in this machine http://www.archivist.info/cnc/works2008/P1010239.JPG it is about 3" and very thin
[05:07:21] <archivist> we used that for gear cutter sharpenning
[05:08:50] <_abc_> Is the wheel the item on the left in the tray?
[05:09:05] <_abc_> We use something very similar
[05:09:07] <_abc_> Just a second
[05:10:47] <archivist> no that is an index plate
[05:11:33] <_abc_> Our machine strongly resembles this one http://www.ebay.com/itm/Universal-cutter-grinder-sharpener-for-end-mill-Twist-drill-lathe-cutter-AUG-/181240643291?pt=AU_HeavyMachinery&hash=item2a32c8bedb but uses a very different wheel, just a second.
[05:12:45] <_abc_> http://www.ebay.com/itm/Universal-Cutter-Grinder-Sharpener-Machine-MR-U2-Negative-Angle-0-25-Degree-/331161478761?pt=UK_BOI_Metalworking_Milling_Welding_Metalworking_Supplies_ET&hash=item4d1ac32669 uses a wheel like this one
[05:12:53] <_abc_> Is that what you need?
[05:12:55] <_abc_> archivist: ^
[05:13:15] <_abc_> There are also flatter wheels and smaller ones, what I need is a smaller one
[05:13:53] <_abc_> The one I have has a too large edge readius for small flutes and is so large it cuts into the movable tool holder 'roof' on the bottom.
[05:14:42] <archivist> no those are too large to fit in small watch gear cutters
[05:15:04] <_abc_> okay, does the hub use a 20mm hole? The axle?
[05:15:43] <archivist> total thickness was about 10mm , I never took the wheel off the spindle so dont know the hole dial
[05:15:48] <_abc_> Also the machine is not too large, trust me, I sharpen 0.2mm tip diameter end mills in it
[05:16:13] <_abc_> archivist: The hole is critical because of high rpm. Some are metric, some are inches. If you get the wrong one you will never true it
[05:16:31] <archivist> I realise :)
[05:16:33] <_abc_> I tried, we got a wheel and I tried to make it fit. Was not nice.
[05:16:46] <_abc_> Also busted a few salvageable mills while trying to use it
[05:17:35] <archivist> I make packing rings when making stuff fit
[05:18:27] <_abc_> The machine looks large but it is a knockoff of a 1940s-1950s German design and it is very sturdy. It's actually desktop size, and likely smaller than your item archivist. Besides Chinese crap issues like wobbly axle bearings on the tool holder and casting defects in the mostly cast iron casing and tool holder it is ok.
[05:20:29] <_abc_> archivist: What's your exterior wheel diameter?
[05:20:44] <_abc_> eBay seems to stock a lot of 100mm and 50mm wheels
[05:20:58] <_abc_> I assume your machine is Imperial so look for 2in wheels?
[05:21:07] <archivist> that machine I showed is actually reasonable small and is only designed for gear cutter grinding http://www.collection.archivist.info/searchv13.php?searchstr=safag%20grinder
[05:21:21] <archivist> that is a swiss machine
[05:21:28] <_abc_> safag is Swiss?
[05:21:31] <_abc_> Aha.
[05:22:02] <_abc_> Don't you make your own wheel cutting disks?
[05:22:11] <_abc_> Or is that machine what you use for that
[05:23:33] <archivist> that was at work at previous job but I need to do the same here at home
[05:24:16] <_abc_> So you do not have a safag now?
[05:24:35] <archivist> no....sniff
[05:24:38] <_abc_> You know, you could repurpose a lathe to hold a 100mm wheel in the chuck
[05:25:24] <_abc_> Make some custom holder for the gear wheel blank on the cutter holder, with a dividing disk. But why do you need diamond cutters to cut presumably soft metal?
[05:25:48] <archivist> I have been making a home brew grinder http://www.collection.archivist.info/searchv13.php?searchstr=tool+grinder
[05:27:45] <_abc_> Nice. Looks okay to me.
[05:28:43] <_abc_> How do you use a wheel dresser on these things? I assume you don't? Wrong?
[05:29:35] <_abc_> archivist: Here you can see some non knockoff grinders http://www.thetractorsource.com/Cutter-Grinder/
[05:30:08] <archivist> I hold the dress on the slide
[05:30:31] <_abc_> Yes but a metal wheel with diamond powder cannot be dressed? I assume?
[05:31:17] <archivist> I took a bunch of pictures of various machines at the model engineer ex a few years ago, just updating the descriptions so searchable

[05:40:58] <Tecan> not even a tractor ?
[05:41:07] <_abc_> Be my guest.
[05:42:43] <archivist> _abc_, ok updated the search terms http://www.collection.archivist.info/searchv13.php?searchstr=cutter+grinder+model
[05:42:57] <_abc_> Hm?
[05:43:16] <_abc_> Oh, ok
[05:43:27] <_abc_> The Model Engineer Ratford is not what you need?
[05:43:35] <_abc_> *d
[05:43:45] <_abc_> 1st item on page
[05:47:10] <archivist> the items were not all described so you could not pick out the grinders at the exhibition
[05:48:48] <archivist> I took about 87 pictures that day
[06:21:16] <_abc_> ok, later
[06:23:59] * jthornton wished he knew how to use a cutter grinder
[06:45:31] <archivist> make one and learn :)
[06:48:20] <archivist> what I dont yet fully understand is the grinding direction, it varies
[07:01:39] <JT-Shop> I have plans for one
[07:04:20] <JT-Shop> hmm, my Debian Wheezy box doesn't show up on the network
[07:06:37] <JT-Shop> ah samba is not installed
[07:10:32] <archivist> I have not use samba in a long while, because almost no windows now
[07:12:10] <JT-Shop> I still have two windoze boxes for cad cam
[07:12:41] <JT-Shop> I see it now :)
[07:23:02] <jthornton> too two reboots to see the debian box on this 10.04 box
[08:32:29] <Tom_itx> archivist have you tried lapidary supply for thin blades?
[08:33:15] <Tom_itx> http://www.dadsrockshop.com/blades.html
[08:33:30] <Tom_itx> not sure what size you need
[08:41:32] <archivist> not sure if those would like cutting/sharpening steel cutters, but my old man had a lapidary set up, wonder where the diamond blade went
[08:41:58] <Tom_itx> <Tom_itx> those are pretty small
[08:41:58] <Tom_itx> <Tom_itx> and $$
[08:41:58] <Tom_itx> <Tom_itx> http://www.bonanza.com/listings/Diamond-Coated-Micro-Saw-Blade-Straight-10mm-Health-and-Beauty-/196215269?gpid=18283950120&gpkwd=&goog_pla=1&gclid=Cj0KEQjwn4iiBRDFh76wlfCVuYABEiQAwWJ1IqMk0hqxqX_3ZrvK9VFC9N2MvQxP3YdXkGLu8nYQlfoaAsRT8P8HAQ
[08:41:58] <Tom_itx> <Tom_itx> better price
[08:42:11] <Tom_itx> posted all that in the wrong channel :D
[08:43:06] <Tom_itx> <Tom_itx> http://www.toolking.com/osung-micss10-diamond-coated-micro-saw-blade-straight-10mm/
[08:43:34] <Tom_itx> that went above ^^ nicer price
[08:45:17] * Jymmm hands Tom_itx his medication as he's talking to himself again.
[08:45:24] <Tom_itx> thanks
[08:45:28] <Jymmm> np
[08:45:39] * Tom_itx only has one eye halfway open
[08:45:53] <archivist> I am not sawing am grinding
[08:46:08] <Jymmm> laping?
[08:46:12] <Tom_itx> i know but that's all i could find so far
[08:47:09] <Tom_itx> what about a tile cutting blade?
[08:47:13] <Tom_itx> not thin enough?
[08:47:21] <archivist> one needs a large diameter to give more cutting surface but thin to get into the grooves
[08:47:31] <Tom_itx> those are fairly small diameter
[08:48:16] <archivist> it is the side/corner doing the work not outer edge really
[08:48:16] <Tom_itx> http://www.acmetools.com/shop/tools/dewalt-dw4765?cm_mmc=Google-_-PRODUCTFEED-_-DEWALT-_-DW4765&CAWELAID=600009240000038325&CAGPSPN=pla&catargetid=600009240000517635&cadevice=c&gclid=Cj0KEQjwn4iiBRDFh76wlfCVuYABEiQAwWJ1IvIVHn5Y3JDtAk8chTw7ogty0JHIdtyIRz9nOWqmpaAaAiPz8P8HAQ
[08:48:37] <Tom_itx> .060 thin
[08:48:42] <Tom_itx> cuts side and edge
[08:50:47] <archivist> remember those are coarse in terms of finish too
[08:51:16] <Tom_itx> they make ones for cutting metal too
[08:51:22] <Tom_itx> maybe the same issue there too
[08:52:24] <archivist> how you use the dresser on a wheel sets up how they cut in terms of finish
[08:53:32] <tjtr33> how to use a deckel style cutter grinder http://www.youtube.com/watch?v=RAUtNy0CeX4
[08:53:33] <tjtr33> you use stock cutter blanks, split the end, put form on end, then roll relief behind cutting edge
[08:54:10] <tjtr33> looong vid
[08:56:58] <tjtr33> _methods, it has no value at load time, it _does_ have value at runtime.
[08:59:54] <tjtr33> ive never seen the loupe device the guy checks his cutters with , we always used a comparator ( and had to wait in line :(
[09:02:44] <archivist> this sort of cutter, needs a taper and about .7mm thick at the tip http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_07_10_Barber_Colman/IMG_1263.JPG
[09:03:31] <archivist> and a straight pass therefore not the Deckel type of grinder
[09:05:55] <tjtr33> wow, sharpening that is an ambitious project. i'll stick to single lip
[09:08:41] <archivist> and now that machine is cleaner http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_09_23_Barber_Colman_speedo_gears/IMG_1832.JPG
[09:08:47] <archivist> ish
[09:12:21] <tjtr33> nice work, whats the '6's on the cutter face ( no sense of scale, you work so small! )
[09:14:00] <archivist> 24mm od ish cutter
[09:25:59] <archivist> hmm just found a smaller cutter, 10mm od, 20 teeth and about .25mm slots in front of the teeth
[09:27:50] <tjtr33> .25mm! use wedm to sharpen the faces!
[09:29:15] <archivist> it is what the safag cutter grinder was designed for at the last day job
[09:30:35] <tjtr33> did i see a closed compartment with coolant ?
[09:30:49] <archivist> yes
[09:31:29] <archivist> had an oil spray, often missing the damned job, had to watch it
[10:44:27] <CaptHindsight> JT-Shop: did you find a cold saw that worked well for cutting your aluminum shapes?
[11:02:18] <zeeshan|2> archivist: where do you get your hobs from?
[11:02:36] <zeeshan|2> theyre kind of expensive! :P
[11:12:04] <jthornton> CaptHindsight, I have one that works ok
[11:12:57] <Tom_itx> JT-Shop, how's the new flesh grinder?
[11:13:14] <jthornton> grinds real well
[11:15:31] <archivist> zeeshan|2, some came from flea market stalls some were cheap new, some from random bit boxes
[11:15:55] <zeeshan|2> that cutter that youre cutting the speedogear with
[11:16:02] <zeeshan|2> how much should that typically sell for used?
[11:16:08] <zeeshan|2> (flea market prices)
[11:16:15] <zeeshan|2> online theyre pretty expensive
[11:16:21] <archivist> that was new carbide .4 mod off ebay
[11:16:35] <archivist> under 30 quid
[11:17:09] <archivist> need to trawl long and hard to find though
[11:17:22] <zeeshan|2> something new like that is around 300 bux right?
[11:17:49] <archivist> chinese is cheaper
[11:18:24] <zeeshan|2> im looking at the flea bay
[11:18:31] <zeeshan|2> they vary significantly :P
[11:19:12] <archivist> yup, hence the long trawl to find the good buys
[11:19:39] <zeeshan|2> the ones that seem to look like good quality are made by gleason
[11:19:45] <zeeshan|2> but theyre all in the 500-800 range!!
[11:20:25] <archivist> they are a production tool to make quantity
[11:20:56] <archivist> I do have a mikron hob :)
[11:21:05] <zeeshan|2> http://www.ebay.ca/itm/NEW-GLEASON-GEAR-HOB-ID-93770-000-3-00-SERIAL-NUMBER-001-/291224600705?pt=LH_DefaultDomain_0&hash=item43ce56c081
[11:21:07] <zeeshan|2> so pretty
[11:23:00] <archivist> looks a bit like a worm wheel hob
[11:23:52] <Speedevil> I guess that would cost a little more than $115 new.
[11:24:13] <archivist> lots more
[11:24:56] <archivist> does have all the info on the end unlike my russian hob
[11:25:58] <archivist> that being a topping hob means you can use it on over sized blanks
[11:27:00] <archivist> zeeshan|2, look for a copy of the barber colman hob handbook
[11:27:30] <zeeshan|2> gives you geometries of different hobs for different types of gear cutting?
[11:27:44] <zeeshan|2> i would really like to make some automotive straight cut gears
[11:27:52] <zeeshan|2> for my transmission
[11:28:38] <archivist> hehe http://www.ebay.co.uk/itm/Barber-Colman-hob-handbook-First-Edition-1954-/200830218558 when O load that page it tells me I won it
[11:28:47] <archivist> o/I
[11:29:50] <zeeshan|2> i got an offer
[11:29:54] <zeeshan|2> on both my bosch tr10 servo amp
[11:29:58] <zeeshan|2> i have it up for 850 USD shipped
[11:30:02] <zeeshan|2> the guy offered 500
[11:30:29] <zeeshan|2> "I would like to buy this item. I would like you to send me all 8 of the circuit boards only. You could sell the rest or throw it away.If you can box the boards carefully and tell me what size the box is I will email you a shipping label,paper work"
[11:30:49] <zeeshan|2> i think thats a fair deal
[11:32:59] <Speedevil> As long as he's legit
[11:33:46] <zeeshan|2> has 54 feedback
[11:33:48] <zeeshan|2> the other guy has 108
[11:33:57] <zeeshan|2> both look like buyers only
[11:33:59] <zeeshan|2> not sellers ever
[11:35:59] <archivist> push for more moneys, probably one of the companies that sells boards for a few k each to the end users
[11:38:28] <zeeshan|2> what's the best way to send a couple of circuit boards
[11:38:35] <zeeshan|2> i was thinking bubble wrap
[11:38:40] <zeeshan|2> and a hardwood box?
[11:38:51] <zeeshan|2> with cardboard around it?
[11:39:16] <zeeshan|2> archivist: i'm happy with the 500
[11:39:26] <zeeshan|2> it buys all 5 axis servo drives
[11:39:29] <zeeshan|2> for my machine
[11:39:40] <zeeshan|2> and from the other controller, it buys all the vfds and gives me some money extra :)
[11:44:33] <Speedevil> How heavy is the drive?
[11:44:37] <Speedevil> other than the boards
[11:44:45] <zeeshan|2> total is prolly 80 lb
[11:44:49] <zeeshan|2> with the boards only about 40
[11:44:55] <zeeshan|2> the metal casing is pretty beefy
[11:45:04] <zeeshan|2> actually boards only about 20
[11:45:05] <zeeshan|2> not 40
[11:49:33] <somenewguy> does anyone know of a cleaner way of finding the sign of a value in gcode than <value>/abs[<value>]
[11:51:19] <archivist> you can branch on value
[11:51:38] <somenewguy> hmm?
[11:52:45] <archivist> http://linuxcnc.org/docs/html/gcode/o-code.html#sec:conditional
[11:53:39] <archivist> what are you actually doing
[11:54:20] <somenewguy> I need to multiply all values by the correct sign for my subroutine to be agnostic of input sign
[11:54:28] <archivist> eg look for LT in http://linuxcnc.org/docs/html/gcode/o-code.html#sec:looping
[11:54:43] <somenewguy> I just want to keep my code readable so I was hoping there was something a little more obvious than value/absvalue to get a sign value
[11:54:52] <somenewguy> like sign[] lol but I guess not
[11:55:16] <archivist> abs probably does what you want then
[11:55:29] <somenewguy> but my box cuttting routine is about to start supporting filleted corners, so yay for that
[11:55:33] <somenewguy> yeah it does work
[11:55:53] <archivist> nobody said gcode was pretty :)
[11:55:59] <somenewguy> Just was curious if there was something more obvious when you scroll thru the code quickly, as gcode gets ahrd to read quickly, even w/ comments
[11:56:05] <somenewguy> I suspect that is true lol
[11:56:15] <somenewguy> although syntax highlighting in sublime sure does help
[11:56:33] <somenewguy> esp the ERROR scope lol
[11:56:40] <archivist> being an assembler programmer helps too
[11:56:54] <somenewguy> too young, I escaped that experience
[11:56:58] <somenewguy> :P

[12:01:52] <somenewguy> srsly?
[12:01:55] <zeeshan|2> yea
[12:01:56] <zeeshan|2> :D
[12:02:02] <somenewguy> I did not see that coming
[12:02:55] <somenewguy> which mean guy again, there are a lot of them lol
[12:03:14] <zeeshan|2> me
[12:03:23] <zeeshan|2> im always ruffling vs ssi and pete

[12:12:19] <zeeshan|2> found a pic of the truck break down too
[12:12:20] <zeeshan|2> lol
[12:12:31] <zeeshan|2> i always giggle when i see a truck pulling another truck
[13:11:05] <archivist> for when you need an excuse http://www.collection.archivist.info/searchv13.php?searchstr=cast+iron+alibi
[13:13:45] <zeeshan|2> haha
[13:13:47] <zeeshan|2> that's cool
[13:13:56] <zeeshan|2> letters are a pain in the ass to cast
[13:14:06] <zeeshan|2> i guess thats why he has the massive draft
[13:14:16] <Speedevil> Are they scraped flat though?
[13:14:32] <zeeshan|2> looks like belt sanded flat
[13:16:57] <archivist> I am just fixing image titles and was amused
[13:53:12] <JT-Shop> anyone know how to share files on debian wheezy with no password needed
[13:55:42] <zeeshan|2> FTP?
[13:55:44] <zeeshan|2> anonymous? :D
[13:55:51] <JT-Shop> LAN
[13:56:26] <zeeshan|2> w/ a windows computer?
[13:56:38] <zeeshan|2> debain -> windows computer?
[13:56:44] <JT-Shop> with both linux and windoze
[13:56:53] <zeeshan|2> to talk to windows youre gonna need to install
[13:56:54] <zeeshan|2> "samba"
[13:57:01] <JT-Shop> have that
[13:57:39] <JT-Shop> I can see the debian computer on all other computers I just can't get to any directories
[13:57:55] <JT-Shop> and right click does not bring up the share option like ubuntu
[13:58:29] <zeeshan|2> http://debian-handbook.info/browse/stable/sect.windows-file-server-with-samba.html
[13:58:55] <JT-Shop> thanks been searching all day for some info
[13:59:06] <zeeshan|2> np
[14:06:23] <cox> JT-Shop: Samba reqires samba user and password, it is not always the same as linux user try this link http://www.cyberciti.biz/faq/adding-a-user-to-a-samba-smb-share/
[14:07:51] <cox> JT-Shop: I guess Ubuntu adds a samba user behind the seens when u add ubuntu user
[14:08:01] <toastyde1th> samba respects PAM
[14:08:56] <toastyde1th> most things that respect PAM include the standard authentication methods, and then fall back to other auth methods - iirc this is how Samba rolls; it looks at etc/passwd first, then its own authentication
[14:09:03] <JT-Shop> dunno in ubuntu you can right click on directory and share it
[14:10:11] <cox> JT-Shop: are you a menber of sambashare try command groups
[14:10:53] <JT-Shop> I'm trying out GADMIN-SAMBA at the moment
[14:14:29] <cox> To list samba users configured on your system you could use this command sudo pdbedit -L -v
[14:15:30] <JT-Shop> john@debian:~$ sudo pdbedit -L -v
[14:15:30] <JT-Shop> [sudo] password for john:
[14:15:31] <JT-Shop> Ignoring unknown parameter "update encrypted"
[14:15:43] <JT-Shop> other than that it listed the users
[14:17:04] <cox> where your user listed
[14:17:17] <cox> The user you are loged in as
[14:18:26] <JT-Shop> yes
[14:19:02] <cox> Did you check the groups command
[14:19:31] <cox> are you a member of sambashare
[14:20:00] <JT-Shop> looking at /etc/samba/smb.conf at the moment
[14:20:20] <Rab> JT-Shop, if there's no automatic way to share the directory, it has to be added to smb.conf.
[14:21:23] <JT-Shop> just trying that now, lol I added a share and it thinks it is a printer on windoze
[14:21:29] <Rab> Type 'testparm -v' to see what Samba thinks it's sharing.
[14:22:14] <JT-Shop> http://pastebin.com/2ss1j0qV
[14:22:59] <Rab> Type 'smbclient -L [hostname]' to see which shares are available. I think that works even if you aren't authenticated for a particular share.
[14:23:25] <JT-Shop> result of testparm -v http://pastebin.com/Y8UWCcfc
[14:23:45] <Rab> I don't see any specific shares.
[14:24:08] <Rab> Maybe your home directory, if you log on as yourself.
[14:26:05] <Rab> Probably better to look for a tutorial on setting up sharing from scratch, so you understand all the concepts. It's not hard, but if debian doesn't provide a shortcut like ubuntu you probably have to do it the long way.
[14:26:25] <JT-Shop> looks that way
[14:28:21] <zeeshan|2> how can you share files between linux computers?
[14:28:23] <zeeshan|2> ive never done that before
[14:28:30] <Rab> Samba.
[14:28:31] <zeeshan|2> i might need it for mill and lathe to talk to teach other
[14:28:33] <zeeshan|2> ah
[14:28:40] <archivist> or ftp
[14:28:43] <zeeshan|2> ftp is hacks
[14:28:45] <zeeshan|2> :)
[14:28:50] <zeeshan|2> drop and drop ftw!
[14:28:51] <Rab> Yeah, actually, SCP would be way faster and easier.
[14:28:51] <archivist> or email them across
[14:28:52] <cox> to be able to add shares automaticaly you need to be member of samba shares.
[14:29:01] <Rab> And automated, with keys.
[14:29:06] <cox> sorry sambashares
[14:29:11] <Rab> Or rsync.
[14:29:13] <archivist> sftp
[14:29:27] <archivist> a usb stick and walking
[14:29:41] <zeeshan|2> usb stick and walking?!?!
[14:29:46] <zeeshan|2> you think i have that much energy? :D
[14:29:57] <Rab> With scp, you don't need any service running besides ssh.
[14:30:00] <zeeshan|2> one thing i realized that i totally forgot on the lathe conmtroller is
[14:30:05] <zeeshan|2> theres no external usb connector!!!
[14:30:09] <archivist> too lazy to plug the network cable in
[14:30:15] <zeeshan|2> i have to open the case to access the usb connector
[14:30:15] <zeeshan|2> lol
[14:30:41] <archivist> actually I have no cable to the upstairs machine
[14:30:42] <Rab> zeeshan|2, that's a sad story. Surely you have a punch to add a panel-mount USB connector.
[14:30:49] <zeeshan|2> no i dont :(
[14:30:58] <Rab> zeeshan|2, you could make a punch.
[14:30:58] <zeeshan|2> i will need to put plastic and tape on the other side
[14:31:04] <zeeshan|2> and dremel it out
[14:31:12] <Rab> Use a nibbling tool!
[14:31:19] <zeeshan|2> rab isn't it a rectangular hole
[14:31:27] <Rab> Sure!
[14:31:48] <Rab> http://www.kleintools.com/catalog/cutting-notching-tools/nibbler-tool
[14:31:49] <zeeshan|2> it's just stupid i forgot about it
[14:31:51] <JT-Shop> SWEET! I got it to work
[14:31:54] <Rab> Best investment you can make.
[14:32:03] <archivist> why model engineers need cnc http://www.collection.archivist.info/searchv13.php?searchstr=eagle+engine
[14:32:03] <JT-Shop> http://www.howtoforge.com/samba-server-install-on-debian-7-wheezy
[14:32:04] <zeeshan|2> the case is 14 gauge steel
[14:32:37] <Rab> zeeshan|2, use kung-fu grip.
[14:32:45] <zeeshan|2> i soemtimes wish i was superman
[14:32:49] <zeeshan|2> id use my finger nails to cut metal
[14:32:55] <zeeshan|2> can you imagine how handy that would be?
[14:33:00] <zeeshan|2> you wouldn't need a lathe or mill anymore
[14:33:03] <zeeshan|2> do everything by hand
[14:33:10] <Rab> Work in pure gold plate. Or lead.
[14:33:16] <zeeshan|2> haha
[14:33:25] <zeeshan|2> delicious lead
[14:33:27] <Rab> Or, I guess, depleted uranium.
[14:33:27] <zeeshan|2> tastes so sweet
[14:33:36] <Jymmm> zeeshan|2: Let's just hope you never encounter the Invisible Man.
[14:33:58] <zeeshan|2> remember the days when kids use to lick lead paint
[14:34:00] <zeeshan|2> cause it was sweet
[14:34:05] <zeeshan|2> one of those kids was me
[14:34:06] <zeeshan|2> :-(
[14:34:17] <zeeshan|2> i used to get slapped by my mom for it
[14:34:17] <zeeshan|2> haha
[14:34:37] <zeeshan|2> Jymmm: who's the invisible man
[14:34:42] <Jymmm> zeeshan|2: So, who slaps you now when you do it?
[14:34:50] <zeeshan|2> no one muaheoaheoaha.
[14:34:58] <zeeshan|2> i'm kidding, lead is some toxic crap
[14:35:02] <zeeshan|2> don't lick it!
[14:35:15] <zeeshan|2> makes a great hammer
[14:35:17] <Jymmm> so are frozen steel poles
[15:02:09] <CaptHindsight> http://www.youtube.com/watch?v=HuecoWOo2l4 MAG welder based metal 3D printer. Apparently good for making pools of metal.
[15:13:19] <tjtr33> my program has some .010inch dia circles.
[15:13:20] <tjtr33> how to get AXIS to zoom in far enouf to see 'em? (theres some 'wall' on zooming in)
[15:18:27] <zeeshan|2> CaptHindsight: a robotic mig welder? :D
[15:23:15] <tjtr33> at first i thought the guy was moving it, but i think he's just triggering it
[15:38:46] <fenugrec> Hi fellas, I can't get G76 threading to work on my lathe. I have spindle-at-speed connected, encoder.0.index-enable connected and working; encoder.0.position working. When I "M4 S200; G0 X0 Z-250; g76 p1 z-260 I0.1 J0.025 K0.5 Q29 R2 " the tool moves to X=0.125 and then waits for something.
[15:39:23] <zeeshan|2> are you using the "near" component
[15:39:39] <fenugrec> yes
[15:40:36] <fenugrec> I just noticed, while using Hal Meter, sometimes the "near" output will have some glitches - can this be the problem ? (I have setp rpmnear.scale 1.03)
[15:40:58] <zeeshan|2> by glitches do you mean
[15:41:01] <zeeshan|2> it goes to true and then off
[15:41:06] <zeeshan|2> but mostly stays true?
[15:41:12] <fenugrec> exactly
[15:41:21] <zeeshan|2> i dont think that matters too much
[15:41:25] <zeeshan|2> on the first incident of true
[15:41:28] <zeeshan|2> it should start moving
[15:41:34] <zeeshan|2> mine does the same thing
[15:41:46] <zeeshan|2> though now that i think about it, i should probably pass it through the debounce filter
[15:42:17] <fenugrec> ok. Once thing I noticed; encoder.0.position is reset to 0 when I enter G76, but then increases continuously past 1.0
[15:43:08] <zeeshan|2> i forget exactly
[15:43:13] <zeeshan|2> but arent you compariing spindle velocity
[15:43:16] <fenugrec> Should it "warp" back to 0 automatically ? My understanding was that motion.index-enable took care of that
[15:43:17] <zeeshan|2> w/ spindle command?
[15:43:25] <zeeshan|2> spindle velocity pin is associated with encoder.0.velocity
[15:43:52] <zeeshan|2> i would monitor encoder.0.velocity
[15:43:58] <zeeshan|2> and see what value it's telling you
[15:44:04] <zeeshan|2> and see if it's close to your command value
[15:44:10] <zeeshan|2> i'd first sort that out..
[15:45:07] <zeeshan|2> is your encoder setup as quadrature
[15:45:10] <zeeshan|2> or phase a and index pulse?
[15:45:14] <fenugrec> I have encoder.0.velocity => rpmnear.in2 => motion.spindle-speed-in
[15:45:57] <zeeshan|2> monitor encoder.0.velocity
[15:46:17] <zeeshan|2> do a m03 s300 for example
[15:46:22] <zeeshan|2> and see if it matches with the commanded value
[15:46:43] <fenugrec> encoder.0.velocity = 3.29 (Hz, fits with S200)
[15:47:17] <zeeshan|2> what is spindle command value?
[15:47:38] <fenugrec> motion.spindle-speed-out-rps = -3.33
[15:47:49] <zeeshan|2> -?
[15:47:50] <fenugrec> I run this through an "abs" component before "near"
[15:47:54] <fenugrec> (counterclockwise)
[15:48:05] <zeeshan|2> whats youe near.0.scale ?
[15:48:07] <zeeshan|2> *your
[15:48:46] <fenugrec> rpmnear.scale = 1.02
[15:49:05] <fenugrec> Just for fun I also set rpmnear.difference=0.1 (== 6 RPM)
[15:49:45] <zeeshan|2> well according to your scale
[15:50:13] <zeeshan|2> the you can be anywhere from 3.26 <= 3.33 <= 3.39
[15:50:23] <zeeshan|2> where 3.29 falls within that range
[15:50:35] <fenugrec> rather 3.23 <= 3.33 <= 3.43 because of rpmnear.difference
[15:50:38] <fenugrec> it's even more permissive
[15:50:41] <zeeshan|2> oh
[15:50:53] <zeeshan|2> that is really weird that its not working
[15:51:19] <fenugrec> So yeah, spindle-at-speed ( driven by the output of rpmnear) seems to work well - like you said, almost always true but some short "false" glitches
[15:51:48] <zeeshan|2> you can pass the velocity through debounce component
[15:51:50] <zeeshan|2> to get rid of them
[15:51:53] <fenugrec> OK, I'll go back a few steps and try G33 instead. hang on.
[15:51:56] <zeeshan|2> but i dont think they are the issue
[15:54:19] <fenugrec> hmm, G33 works (although a bit irregular with S200)
[15:55:57] <fenugrec> I had to put a negative K though (to go from Z-250 to Z-260), the manual wasn't clear about that
[15:56:51] <zeeshan|2> haah
[15:56:53] <fenugrec> Obviously a negative pitch with G76 doesn't work hehe
[15:56:55] <zeeshan|2> so it was a g-code error
[15:57:11] <fenugrec> yeah, but G76 still doesn't work
[15:57:20] <zeeshan|2> if g33 is working
[15:57:27] <zeeshan|2> then you know its a g-code error
[15:57:47] <zeeshan|2> actually itake that back
[15:57:53] <zeeshan|2> it could be something to do with encoder position
[15:58:03] <R2E4> Hey all......
[15:58:08] <R2E4> IS pcw around?
[15:58:22] <zeeshan|2> wait sorry
[15:58:24] <fenugrec> zeeshan|2, do you have a known-good G76 line I can try then. I can't see anything wrong with mine
[15:58:27] <zeeshan|2> g33 is spindle sync
[15:58:33] <zeeshan|2> so if g33 is working it will work.
[15:58:44] <zeeshan|2> fenugrec: sorry i dont, i use mastercam to spit out g33
[15:59:02] <R2E4> Working on a cnc router and wondering if these servo motors would work with the 7i77. http://www.automationdirect.com/static/specs/sureservolowmed.pdf
[15:59:16] <R2E4> The drive is pulse and direction
[16:00:29] <zeeshan|2> maybe through H0 and L0?
[16:00:39] <zeeshan|2> otherwise your g76 code looks good
[16:01:45] <zeeshan|2> r2e4
[16:01:52] <zeeshan|2> i see that it accepts "analog velocity/torque"
[16:01:56] <zeeshan|2> so it should work.
[16:02:31] <zeeshan|2> pcw recommended 7i77 for me
[16:02:33] <zeeshan|2> for analog vel mode
[16:02:56] <fenugrec> zeeshan|2, I tried some variations (including H0, L0, R1, R2), still no dice - it rapids in X to the depth of the first cut, then waits there for who-knows what
[16:03:03] <zeeshan|2> haha
[16:05:00] * zeeshan|2 suggests using g33!
[16:05:00] <zeeshan|2> :D
[16:06:02] <fenugrec> fndsfkndsf
[16:06:19] <fenugrec> I like the R parameter of linuxcnc. I can't see how to do that in proE
[16:07:06] <zeeshan|2> are you using wildfire
[16:07:15] <fenugrec> WF4
[16:07:20] <fenugrec> and Creo2
[16:07:25] <fenugrec> but mostly 4
[16:07:43] <zeeshan|2> weird that it cant do that
[16:08:01] <fenugrec> it might, I haven't found the right parameter yet
[16:08:30] <zeeshan|2> i found someones g-code
[16:08:34] <zeeshan|2> on youtube
[16:08:37] <zeeshan|2> http://www.youtube.com/watch?v=7duqP-d68bU
[16:08:51] <zeeshan|2> try that in free air? :P
[16:09:03] <zeeshan|2> looks like its in mm too
[16:09:29] <fenugrec> hmm I managed to freeze AXIS.wtf
[16:09:31] <R2E4> zeeshan|2 with which drives
[16:09:46] <zeeshan|2> R2E4: for my bosch tr10 drives
[16:09:53] <zeeshan|2> but itll alsow ork with AMC BE series drives
[16:09:57] <R2E4> I didnt see velocity. I'll check again. I used the 7i77 also on my vmc. Its bad ass....
[16:10:38] <zeeshan|2> in that pdf
[16:10:40] <zeeshan|2> page 5
[16:10:49] <zeeshan|2> look under heading I/O interface
[16:11:07] <zeeshan|2> right side
[16:11:49] <zeeshan|2> R2E4: how much are those drives?
[16:12:48] <zeeshan|2> nm
[16:12:52] <zeeshan|2> expensive! :D
[16:17:21] <fenugrec> brb
[16:23:03] <fenugrec> zeeshan|2, I tried that guy's G76 line almost verbatim... same thing
[16:34:53] <fenugrec> could it be because the encoder always gives a positive velocity and increasing position, but since I work CCW, motion expects a negative velocity ?
[16:36:15] <fenugrec> HAHAH
[16:37:01] <fenugrec> that was it. But how can it be ? Does everybody thread CW on their lathes??
[16:37:53] <fenugrec> For a conventional lathe, my understanding is that M4 = CCW = "normal" direction
[16:43:19] <SquirrelCZECH> nah
[16:43:25] <SquirrelCZECH> I have cnc-style machine (3d printer)
[16:43:42] <SquirrelCZECH> if I add weight, increasing the center of mass
[16:43:49] <SquirrelCZECH> can it ahrm the quality of products? :)
[16:44:45] <Nick001-shop> On most lathes M3 = ccw - top of chuck coming at you standing in front of machine
[17:02:14] <fenugrec> Nick001-shop, that would explain a lot, but it seems counter-intuitive : Z+ is to the right, X+ is towards you, so Y+ is towards the floor - then "top of chuck coming at you" should be CCW... anyway. At least I found my problem now
[17:08:04] <CaptHindsight> SquirrelCZECH: what are you trying to figure out?
[17:14:36] <SquirrelCZECH> CaptHindsight: just instlled this http://www.thingiverse.com/thing:302854
[17:14:44] <SquirrelCZECH> and started to worry about center of mass
[17:25:36] <Deejay> gn8
[17:55:38] <fenugrec> so... what is the definition of "clockwise" on a lathe ?
[18:05:53] <Jymmm> fenugrec: The opposite of CCW silly! *rolls eyes*
[18:52:36] <somenewguy> fenugrec: I assume it is based on the motion of the tool relative to the workpiece as most moves are, but I am not sure
[18:53:28] <somenewguy> so if you are standing next to the lathe, jaw to your left, tool post in ur belly, if the top of the jaws are coming toards you that is CW
[18:54:47] <somenewguy> http://linuxcnc.org/docs/html/common/images/lathe-diagram.png
[18:54:58] <somenewguy> that image should probably have a spindle direction arrow or two to clarify things
[18:58:51] <somenewguy> so folks there is that nice webpage w/ a bunch of python tools for linuxcnc g-code generation, is there an equivalent for ngcgui tools?
[18:58:56] <somenewguy> the one in the forum is a little, uh sparse
[18:59:10] <somenewguy> or are all the ones that ship w/ linuxcnc the bulk of what exists out there in the wild
[19:00:51] <somenewguy> Nick001-shop: so I guess I have it backwards? CW vs CCW is relative ot the direction of the face of the chuck, not the travel of the tool relative to the workpiece
[19:09:28] <fenugrec> somenewguy, so you see it's not obvious. If you look at the chuck, from the toolpost, CCW looks "normal" but apparently that's called CW. If you take a product vector of X+ and Y+ (giving Z+), and call that CCW (like I did), apparently that's also wrong
[19:11:46] <fenugrec> but I found no official word on this. The only convention is "M3=CW, M4=CCW"
[19:21:03] <Nick001-shop> Back in 1/2 hr - supper
[19:21:19] <fenugrec> Ah, got it. I think RS274 defines "clockwise" as "looking out from the spindle face"
[19:21:32] <fenugrec> that's what machinery's hbk says, at least.
[19:21:59] <fenugrec> That should definitely be added to the docs to prevent morons like me wasting 6hrs trying to thread "backwards" with g76
[19:50:35] <fenugrec> aaaarg I think I'm getting spurious Index pulses from my encoder, it's mangling my threads
[19:51:42] <zeeshan|2> did you shield the encoder cable?
[19:51:55] <zeeshan|2> did you get your g76 working?
[20:22:29] <fenugrec> zeeshan|2, I got G76 "sortof" working (now that I clarified CW/CCW") but I'm getting what appears to be a 80-entry thread p-)
[20:22:55] <fenugrec> I'm checking the cabling right now, but it might just be the index pulse sensor that's misaligned
[20:27:46] <zeeshan|2> does alignment matter a lot? :P
[20:28:09] <zeeshan|2> how many slots is your trigger wheel
[20:28:22] <zeeshan|2> http://i.imgur.com/njCNjKP.jpg
[20:28:41] <fenugrec> 80/rev + 1/rev slots
[20:28:43] <zeeshan|2> i kinda eye balled it
[20:28:44] <zeeshan|2> :D
[20:29:29] <zeeshan|2> ok yours is more precise than mine
[20:30:04] <fenugrec> I don't have the pic anymore, but mine has 2x3mm slots (for the 80/rev) and the index slots is like 2x5mm; it was plastic-printed by a friend of mine but concentricity is not incredible
[20:30:32] <fenugrec> Plus, I had to paint the bloody thing because the white ABS didn't occlude the LED enough !
[20:32:36] <zeeshan|2> you have 2 index slots? :D
[20:32:45] <zeeshan|2> haha
[20:34:15] <fenugrec> nono just 1 index, 2mm*5mm
[20:34:26] <fenugrec> I dropped an "s"
[20:37:28] <zeeshan|2> i thought the slot width
[20:37:34] <zeeshan|2> had to be the same
[20:37:36] <zeeshan|2> as your other slots
[20:37:52] <fenugrec> it is. Depth is 5
[20:38:19] <zeeshan|2> gotcha
[20:38:29] <zeeshan|2> wasn't sure what the dimensions were referring to :)
[20:39:04] <fenugrec> I'll be making another one though, and modifying the sensors to have full quadrature
[20:39:14] <fenugrec> but for now I need this to work
[20:39:20] <zeeshan|2> you need quadrature
[20:39:26] <zeeshan|2> to do LH threads right?
[20:39:38] <zeeshan|2> i forget :p
[20:40:45] <fenugrec> I don't think so - as long as you remember which way the spindle needs to turn
[20:41:22] <zeeshan|2> http://www.youtube.com/watch?v=7vePhuVR3Lc&list=UUy-Z-COl0WvPmSLXMOvtedg
[20:41:27] <zeeshan|2> i found my threading video :D
[20:46:58] <fenugrec> coming soon to a lathe near me
[20:48:00] <zeeshan|2> what lathe are you working on
[20:50:46] <fenugrec> Denford easiturn 3 ( http://www.wotol.com/images/thumbs/800x800/198401_4037e79c23581764c8520817fb5469f9.jpg without the computer-box on top)
[22:06:56] <Connor> pcw_home: Do you have any interface cards or anything that gives you a high speed encoder input using RS-422 expansion ?
[22:07:22] <Connor> from the 5i25 + 7i75
[22:07:25] <Connor> err. 7i76
[22:09:18] <somenewguy> fenugrec: so to be clear, CW is the "normal" lathe direction of rotation?
[22:09:30] * somenewguy does not own a lathe
[22:09:33] <pcw_home> No, there are no full axis encoders as serial remotes
[22:10:06] <Connor> pcw_home: What are the ENC422 and 422ENC board for ?
[22:10:17] <somenewguy> oh and for shielded cable, what do you guys normaly use? I have no encoders so I don't ahve a need currently
[22:10:39] <somenewguy> it sounds like ppl typically add shieldsto existing cables, why not just use cut up USB cable or somesuch?
[22:11:30] <pcw_home> one channel TTL --> DIFF and DIFF --> TTL redrivers
[22:13:37] <Connor> pcw_home: Okay, so nothing to do with the RS-422 expansion port on the 7i76
[22:14:43] <pcw_home> Made for I/O expansion
[22:15:26] <zeeshan|2> how many more i/os
[22:15:28] <zeeshan|2> can you get?
[22:15:38] <zeeshan|2> pcw_home: im about to place an order from mesa
[22:15:46] <zeeshan|2> can you please confirm if i need anything else
[22:15:54] <zeeshan|2> so far im getting the 7i77 and 5i25 kit
[22:16:49] <Connor> zeeshan|2: You might want the DIN rail brackets..
[22:17:12] <fenugrec> somenewguy: yes, CW is the usual direction you would use on a manual lathe.
[22:17:17] <Connor> for the 7i77...
[22:17:38] <fenugrec> somenewguy : but if your sitting on the toolpost looking at the chuck, it will look like CCW
[22:17:43] <fenugrec> *you're
[22:17:53] <zeeshan|2> remember guys
[22:17:55] <zeeshan|2> its right hand rule
[22:18:05] <zeeshan|2> positive z is away from the chuck
[22:18:14] <zeeshan|2> if your thumb points in the direction of the z axis
[22:18:30] <zeeshan|2> your fingers rotation gives you + direction of rotation
[22:18:42] <fenugrec> zeeshan|2, it's also "viewed *from* the spindle face"
[22:19:26] <zeeshan|2> right hand will give you the correct answer as long as you define your coordinate system using right hand rule
[22:19:28] <zeeshan|2> :D
[22:20:25] <zeeshan|2> like if you define towards spindle +z
[22:20:31] <zeeshan|2> and towards you +x
[22:20:39] <zeeshan|2> then its no longer a right handed coordinate system
[22:20:57] <zeeshan|2> connor din rail brackets ordered
[22:20:59] <zeeshan|2> anything else? : D
[22:21:07] <fenugrec> zeeshan|2, X hand rules suck. It's better to know what a vector product is (i.e. "X+ vector (X) Y+ vector gives Z+; it's like turning a bolt from X+ to Y+ and so it "unscrews" and moves up Z+)
[22:21:48] <zeeshan|2> fenugrec: without right hand rule in mechanics
[22:21:51] <fenugrec> there's right hand rules for coord sys, hand rules for magnetic fields (but it's the opposite if you use electron flow instead of positive flow", etc
[22:21:51] <zeeshan|2> we'd be all confused :D
[22:21:54] <Connor> zeeshan|2: The only other possible thing you might want is the 7i73 Pendany Control panel interfcae..
[22:22:28] <Connor> that would let you have a remote pendant (custom build of course) up to 30 Meters away using RS-422 interface.
[22:22:41] <fenugrec> it's a mess, confusing and looks retarded when you do it. I refuse to use X-hand rules
[22:22:50] <zeeshan|2> haha fenugrec i guess its preference
[22:22:58] <zeeshan|2> if you dont conform to them
[22:23:13] <zeeshan|2> then rh and lh thread are meaningless :P
[22:23:30] <zeeshan|2> cause then it will all depend on which way you look at the bolt from
[22:23:45] <zeeshan|2> as long as you get the right answer, who cares right? :D
[22:24:03] <zeeshan|2> connor i'd like to use a usb pendant
[22:24:05] <fenugrec> of course not !! Hold an RH bolt "upside down", if you turn it CW it will screw "away" from you
[22:24:12] <fenugrec> just as it does when "rightside up"
[22:24:29] <fenugrec> I came here for an argument
[22:24:32] <zeeshan|2> yea but lets say you're takling the cross product of two vectors
[22:24:39] <zeeshan|2> how do you know which way that third vector points
[22:24:44] <zeeshan|2> you know its normal
[22:24:48] <Connor> zeeshan|2: More thinking about your main console if your going to have a integrated MPG and buttons and stuff..
[22:24:58] <zeeshan|2> connor no main console
[22:25:01] <zeeshan|2> just computer interface
[22:25:02] <zeeshan|2> and mpg
[22:25:15] <Connor> and the 7i77 is going to be far enough away to make it painful to run wires between..
[22:25:17] <zeeshan|2> ideally i'd like it to be touch screen
[22:25:31] <zeeshan|2> so you no longer need any buttons except e-stop
[22:25:33] <Connor> I'm doing touchscreen, will have a MPG, and a few hard wired buttons.
[22:25:41] <zeeshan|2> what will be your hard wired buttons
[22:25:50] <somenewguy> DIN rail mounting makes life so much easier
[22:26:06] <fenugrec> zeeshan|2, yes, cross product is what I was describing. I always view it like turning a wrench on a bolt - your handle is on the X+ axis, turn 1/4 turn (handle now on Y+), then visualize which way the bolt went. That direction is Z+, the result of cross prodct
[22:26:25] <somenewguy> so that would be the right hand thread rule?
[22:26:28] <Connor> Push-To-Start, E-Stop, maybe a external axis select for the MPG.
[22:26:30] <somenewguy> :P
[22:26:37] <zeeshan|2> you dont have axis select
[22:26:39] <zeeshan|2> on the pendant?
[22:26:49] <Connor> and a power draw release button.
[22:26:54] <somenewguy> oooh what are you doing for a touch screen? I really want to do one of those
[22:27:07] <somenewguy> But I think I am waiting for htem to come down in price first
[22:27:08] <fenugrec> somenewguy, encoders is not too critical for shielded cables - just about anything will do, it's not HF stuff. Just remember to connect the shield both ends
[22:27:54] <Connor> zeeshan|2: I don't have a pendant.. just the main console.. but yes.. you would have a axis select on a pendant.
[22:28:05] <zeeshan|2> ah okasy
[22:28:22] <fenugrec> "data" cable that has a foil shield + drain wire will be quite OK. USB too, although some cheap cheap cables may be of questionable quality (like 3-strand 42Ga conductors that will break the second time you flex them)
[22:28:27] <Connor> I just finished making my DB25 breakout box..
[22:29:26] <Connor> I need to order more ferrule's from digikey.. Running out..
[22:29:36] <zeeshan|2> pcw answer me!! :D
[22:29:58] <Connor> zeeshan|2: He's in the Devel channel helping someone else.
[22:30:03] <zeeshan|2> oh
[22:30:08] <zeeshan|2> connor
[22:30:09] <zeeshan|2> http://store.mesanet.com/index.php?route=product/category&path=74_79
[22:30:14] <zeeshan|2> which din rail adapter is the one i want
[22:30:18] <zeeshan|2> for 5i25 and 7k77
[22:30:20] <zeeshan|2> 7i77
[22:30:33] <Connor> I bought 2 x 2pcs.
[22:30:37] <zeeshan|2> okay
[22:30:45] <Connor> but, I have th 7i76
[22:30:52] <zeeshan|2> same thing
[22:30:56] <zeeshan|2> just analog
[22:30:58] <zeeshan|2> vs step/dir
[22:31:13] <Connor> Different number of mounting points.. Mine has 4.
[22:31:20] <Connor> the 7i77 has 6
[22:31:21] <zeeshan|2> really? :/
[22:31:28] <zeeshan|2> okay then i prolly want the 3
[22:31:36] <Connor> so 2 x 3pcs
[22:31:45] <Connor> or 3 x 2 pcs. :)
[22:31:55] <zeeshan|2> http://store.mesanet.com/image/cache/data/Products/AIO-FPGA-Cards/7i77colo-500x500.png
[22:31:57] <fenugrec> OOO in other news, I *finally* managed to make some threads. Turns out I needed to debounce the encoder inputs
[22:31:57] <zeeshan|2> i see like
[22:32:02] <zeeshan|2> 2390123098312 gazzilion mounting holes
[22:32:09] <zeeshan|2> 6!
[22:32:12] <zeeshan|2> er
[22:32:14] <zeeshan|2> 12
[22:32:21] <Connor> 6 on top, 6 on bottom. the din rail uses 2..
[22:32:27] <Connor> err. din mount uses 2 per.
[22:32:31] <zeeshan|2> fenugrec: you might be getting noise in your encoder signal?
[22:32:37] <zeeshan|2> i didnt have to debounce mine
[22:33:00] <zeeshan|2> ill just wait till pcw chimes in :D
[22:33:05] <zeeshan|2> i dont wanna pay for shipping tiwce :(
[22:33:28] <fenugrec> zeeshan|2, not sure; I scoped the encoder pins right at the PCB, and at the other end of the computa cable, and signal seemed OK. Well obviously it wasn't, because with the HAL scope I was getting spurious pulses on both phase-A and phase-Z
[22:33:30] <Connor> 3 servo's + spindle right ?
[22:33:34] <zeeshan|2> no
[22:33:36] <zeeshan|2> 5 servos
[22:33:37] <zeeshan|2> + spindle
[22:33:44] <Connor> you have 5 servos ?
[22:33:48] <zeeshan|2> yea
[22:33:54] <zeeshan|2> for 5 axis
[22:34:03] <Connor> That machine was 5 axis ?
[22:34:04] <zeeshan|2> i have two 1/4 hp dc motors
[22:34:06] <zeeshan|2> no
[22:34:09] <zeeshan|2> im going to make it 5 axis
[22:34:31] <zeeshan|2> i want all the electronics ready for 5 axis
[22:34:48] <zeeshan|2> then use the mill to build the 4 axis table
[22:34:50] <zeeshan|2> er
[22:34:52] <zeeshan|2> 2 axis table
[22:34:57] <Connor> Then your good.
[22:35:08] <Connor> Couldn't think what else you would need.
[22:35:13] <zeeshan|2> for input wise
[22:35:35] <Connor> 7i77 has 32 inputs and 16 outputs..
[22:35:44] <zeeshan|2> yea im using like 5 on the bob currently
[22:35:45] <zeeshan|2> lol
[22:35:59] <Connor> 2 of the 32 will be used for the MPG,
[22:36:08] <zeeshan|2> mpg needs inputs?
[22:36:09] <Connor> you don't have a tool changer do you ?
[22:36:10] <zeeshan|2> i thought it worked through usb
[22:36:14] <zeeshan|2> no tool changer
[22:36:20] <zeeshan|2> maybe id like to in the future, but not anytime soon
[22:36:34] <zeeshan|2> its got a power drawbar on it already
[22:36:35] <zeeshan|2> hydraulic
[22:36:37] <Connor> No, MPG's are hardwire.. I.E. they're encoders.. Pendant's can be USB..
[22:36:40] <zeeshan|2> which should make tool changes okay
[22:36:55] <Connor> okay.. so 1 output for that. maybe a output for the Coolant pump.
[22:37:01] <zeeshan|2> the pendants have the mpg on them
[22:37:02] <Connor> maybe one for airblast.
[22:37:06] <zeeshan|2> like that wireless one
[22:37:08] <zeeshan|2> xhc?
[22:37:20] <zeeshan|2> definitely need 1 output for coolant pump
[22:37:25] <zeeshan|2> which will turn on the vfd
[22:37:34] <Connor> Yes, I'm talking about ones like this... http://www.cnc4pc.com/Store/osc/product_info.php?cPath=40&products_id=163
[22:37:40] <zeeshan|2> ohh
[22:37:43] <zeeshan|2> im talking about this:
[22:37:53] <Connor> MPG != Pendant
[22:38:07] <Connor> A pendant can include a MPG, or just buttons...
[22:38:09] <zeeshan|2> aha i was confusing
[22:38:10] <zeeshan|2> http://i00.i.aliimg.com/wsphoto/v0/1941841020/Free-Shipping-New-Wireless-USB-MPG-Pendant-Handwheel-font-b-Mach3-b-font-For-CNC-Mac.jpg
[22:38:26] <zeeshan|2> http://i.imgur.com/ci50ock.png
[22:38:30] <zeeshan|2> currently thats what i have laid out
[22:38:35] <zeeshan|2> vfd for hydraulic pump, one for coolant
[22:38:37] <zeeshan|2> and spindle
[22:38:48] <Connor> Mine will have a built-in MPG along with hardware button for Push-To-Start, Power-Draw-Bar release.. and not sure what else.
[22:38:52] <zeeshan|2> i will need an encoder on the spindle :(
[22:39:16] <Connor> Does your spindle not have a encoder ?
[22:39:22] <zeeshan|2> no
[22:39:25] <zeeshan|2> i dont thinkso
[22:39:34] <zeeshan|2> i havent taken that panel off
[22:39:39] <zeeshan|2> but i dont see any wires going there that are obvious
[22:39:44] <zeeshan|2> its only one wire going to the motor
[22:39:53] <zeeshan|2> a bundle of wires that is
[22:40:10] <somenewguy> link for that pendand?
[22:40:31] <Connor> Be careful on those.. only get the ones that say they're for Mach3.
[22:40:51] <zeeshan|2> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Using_A_XHC-HB04_Wireless_MPG_Pendant
[22:40:54] <Connor> The other ones are for a proprietary control and won't work with the linuxcnc drivers.
[22:41:01] <somenewguy> as apposed to
[22:41:04] <somenewguy> oh that makes sense
[22:41:05] <zeeshan|2> i remember there was a maunal version for this
[22:41:10] <zeeshan|2> er
[22:41:13] <zeeshan|2> wire version
[22:41:16] <zeeshan|2> not wireless
[22:44:30] <Connor> I'm not seeing the one that's NOT for mach3 now..
[22:44:37] <Connor> They had some on ebay.
[22:45:57] <somenewguy> I remember those pendants being pretty pricey, but that one sounds cheap seeing as how its so popular lol
[22:46:09] <zeeshan|2> wireless scares me
[22:46:10] <zeeshan|2> :(
[22:46:11] <somenewguy> but I am haveing a surprisng amount of time finding them for sale lol, I can find DIY clones tho
[22:46:17] <zeeshan|2> "battery out during +x feed"
[22:46:20] <zeeshan|2> oh noes!
[22:46:22] <zeeshan|2> spindle crash!
[22:46:39] <zeeshan|2> unless when the signal drops
[22:46:40] <zeeshan|2> it stops
[22:46:50] <somenewguy> thats why I have my trusty hard wired sound port joystick to control my mill
[22:46:58] <zeeshan|2> haha
[22:47:01] <somenewguy> *gameport
[22:47:01] <zeeshan|2> somenewguy: what kind of mill
[22:47:08] <somenewguy> taig
[22:47:12] <somenewguy> desktop
[22:47:14] <zeeshan|2> ah
[22:47:49] <somenewguy> When I upgrade the shop I'll go full size, but unitll then this little bastard has been invaluable
[22:48:25] <somenewguy> being able to pretned I have a lathe is awesome
[22:48:37] <somenewguy> without actually loosing precious shop space to more equiptment
[22:51:15] <Connor> http://www.ebay.com/itm/Ncstudio-CNC-3-Axis-USB-wireless-MPG-pendant-Controller-engraving-for-NC-studio-/251582528060?pt=LH_DefaultDomain_0&hash=item3a937cba3c
[22:51:28] <Connor> That's the one to NOT get.. the one for NC studio
[22:51:43] <zeeshan|2> hook me up with alink for wired pendant :D
[22:52:07] <Connor> http://www.ebay.com/itm/CNC-3-Axis-4-axis-USB-HandWheel-MPG-pendant-for-Mach-3-engraving-Router-system-/171194705426?pt=LH_DefaultDomain_0&hash=item27dbffe612
[22:52:15] <Connor> That one.
[22:52:32] <Connor> 4 Axis. has the nicer key layout.. non of that stupid Marco crap
[22:53:08] <zeeshan|2> connor
[22:53:13] <zeeshan|2> i have a mpg that came with this machine
[22:53:15] <zeeshan|2> i wonder if i should use it
[22:53:17] <zeeshan|2> it looks really nice
[22:53:28] <Connor> That would be the one for the console..
[22:53:35] <zeeshan|2> yea
[22:53:39] <Connor> and yes. One at the console is a good idea.
[22:54:23] <Connor> they also have that key layout in wireless..
[23:00:06] <zeeshan|2> do you know if when using the wireless one
[23:00:09] <zeeshan|2> if battery does out
[23:00:15] <zeeshan|2> *goes out whle youre jogging
[23:00:18] <zeeshan|2> it'll stop jogging?
[23:00:25] <Connor> It should
[23:00:35] <Connor> I think they have a dead-man circuit in them so to speak.
[23:00:46] <zeeshan|2> itr'd really suck
[23:00:49] <zeeshan|2> if youre doing something precise
[23:00:52] <zeeshan|2> and boom it does
[23:00:52] <zeeshan|2> lol
[23:01:16] <zeeshan|2> wireless is way more convienient though cause you can get really close to the part when jogging
[23:04:28] <fenugrec> Does anyone know if there's a .ini option to force AXIS to start with "show relative position" activated ?
[23:04:37] <cradek> yes
[23:04:43] <fenugrec> I can't find it
[23:05:30] <zeeshan|2> look under [display]
[23:05:36] <zeeshan|2> i think its position offset
[23:05:37] <zeeshan|2> or something
[23:05:54] <cradek> http://linuxcnc.org/docs/2.6/html/config/ini_config.html#sub:DISPLAY-section
[23:05:56] <cradek> yeah that's it
[23:06:17] <fenugrec> aaah thanks guys I was looking 10 lines too low
[23:06:35] <zeeshan|2> how do you setup
[23:06:39] <zeeshan|2> default g-coides on startup
[23:06:43] <zeeshan|2> my thing always shows radial coordinates
[23:06:45] <zeeshan|2> when i want diameter
[23:06:59] <fenugrec> zeeshan|2, in [RS274NGC] : RS274NGC_STARTUP_CODE = G7 G18 G21 G40 G49 G80 G90 G95
