[01:09:16] <CIA-8> 03jepler 07HEAD * 10emc2/src/hal/utils/scope_disp.c: draw the triggerline only for the right trace, not all of them
[01:10:34] <Dallur> beer's good m,key
[01:11:33] <A-L-P-H-A> yup
[01:11:38] <A-L-P-H-A> agreed. beer's good. :)
[01:11:46] <A-L-P-H-A> so is rum and coke.
[01:12:05] <Dallur> yup, I think GT is next though
[01:12:15] <Dallur> :D
[01:13:40] <A-L-P-H-A> GT? Gin and Tonic?
[01:52:56] <giacus> night
[02:35:15] <CIA-8> 03cradek 07lathe_offsets * 10emc2/src/emc/canterp/canterp.cc: pass lathe tool info through all the layers
[02:35:15] <CIA-8> 03cradek 07lathe_offsets * 10emc2/src/emc/iotask/ioControl.cc: pass lathe tool info through all the layers

[02:35:22] <CIA-8> 03cradek 07lathe_offsets * 10emc2/src/emc/rs274ngc/ (5 files): pass lathe tool info through all the layers
[02:35:24] <CIA-8> 03cradek 07lathe_offsets * 10emc2/src/emc/task/emccanon.cc: pass lathe tool info through all the layers
[02:35:25] <CIA-8> 03cradek 07lathe_offsets * 10emc2/src/emc/usr_intf/ (iosh.cc keystick.cc): pass lathe tool info through all the layers
[02:43:35] <cradek> wow, it even works, we have lathe tool offsets
[02:43:40] <jmkasunich> yay!
[02:44:16] <cradek> we're very, very close to being a useful lathe controller
[02:45:40] <cradek> http://timeguy.com/cradek-files/emc/lathe-offset.png
[02:46:02] <cradek> this is radius compensation with x=.5 z=.5 offset in the tool table
[02:46:13] <cradek> (axis doesn't know about tool offsets)
[02:46:43] <jmkasunich> what are the two lines? to passes?
[02:46:50] <jmkasunich> s/to/two
[02:47:05] <cradek> the top is the actual programmed path, the bottom one is with radius comp turned on
[02:47:12] <cradek> well, top and bottom of each pair
[02:47:26] <cradek> you can see the crazy entry moves on the bottom line
[02:47:27] <jmkasunich> ok, so what are the two pairs (white and red)
[02:48:02] <cradek> the white is ignoring the tool location, the red is the .5/.5 offset
[02:48:29] <cradek> axis doesn't read those offsets from the real tool table, so the preview doesn't line up
[02:48:35] <jmkasunich> oh, ok... I was confusing tool offset and tool radius comp
[02:48:50] <cradek> yeah it's several different things, all working :-)
[02:50:53] <jmkasunich> you've been busy
[02:51:00] <jmkasunich> me too: http://home.att.net/~jmkasunich/Pics/KE01052109.pdf
[02:51:21] <jmkasunich> turning the OD of the gear blank now, then gotta do the throat
[02:51:41] <jmkasunich> really wish I had CNC for that, one arc and done (well, a few passes actually)
[02:51:43] <cradek> cool, I saw your photo of this setup from last time
[02:52:05] <jmkasunich> the teeth are this weekend's project
[02:52:09] <cradek> cutting gears is NOT fun without cnc - it's so easy to lose attention and screw it up
[02:52:13] <jmkasunich> I just want to get the blank finished today
[02:52:40] <cradek> you made the cutter yourself too?
[02:52:47] <jmkasunich> yeah
[02:53:01] <cradek> you're way more of a machinist than I am
[02:53:02] <jmkasunich> did that back in 2001 when I did the first jig, don't need to do it again
[02:53:10] <cradek> ah great
[02:53:43] <jmkasunich> two cutters actually, the drawing shows the gashing cutter, the hob is just a piece of the threaded rod with flutes cut in it and hardened
[02:53:57] <Jymmm> Been looking for my wirewrap tool for three hours... if it was a snake it would have biten my nose off *sigh*
[02:54:13] <cradek> Jymmm: my grandma used to say that
[02:54:14] <jmkasunich> doncha hate it when that happens
[02:54:29] <Jymmm> jmkasunich I'm telling ya...
[02:55:07] <Jymmm> And the REALLY sad part... the last time I used it, I put it in a place so I wouldn't misplace/forget where I stored it!
[02:55:13] <jmkasunich> heh
[02:55:17] <jmkasunich> that will get you every time
[02:55:19] <cradek> that's a sure way to lose stuff
[02:55:26] <cradek> put it somewhere "special"
[02:55:44] <Jymmm> and I looked RIGHT at it 45 minutes ago too... but did I see it. Nooooooooooooooooo!
[02:56:06] <jmkasunich> been there done that
[02:56:26] <jmkasunich> spent an hour looking for something that was in my pocket once
[02:56:47] <cradek> I can beat that, I've looked for stuff I was holding in my hand
[02:57:07] <cradek> just think what it'll be like when we're old
[02:57:10] <Jymmm> I've done that at least once.
[02:57:22] <cradek> that's good of you to admit.
[02:58:05] <Jymmm> usually it's when your working on some POS crap, so pissed casue it's not doing what you KNOW it should be and are ready to start destroying something
[02:58:56] <cradek> I wish my lathe was done to test all this stuff
[02:59:16] <jepler> cradek: get to work on your lathe!
[02:59:17] <cradek> I keep telling myself I won't unpack the coffin (nist lathe) so it encourages me to finish mine instead
[02:59:36] <cradek> jepler: did you see my picture?
[02:59:42] <cradek> http://timeguy.com/cradek-files/emc/lathe-offset.png
[02:59:46] <jepler> cradek: yes I just looked at it
[03:00:16] <jepler> cradek: does this include tool shapes, or just two dimensions worth of offsets?
[03:00:18] <cradek> looks like we'll have to get axis to handle the tool offsets one of these days
[03:00:28] <cradek> just two dims worth of offsets
[03:00:45] <cradek> but I think the rest will be "simple" math in one place
[03:00:54] <Jymmm> Take for example when you have headlight issues that's ohming out correctly but when you go to turn them on no light. Test the lightbulb and socket seperatly all good, then say fuckit and slice open the harness and you find (this is no joke)... a corroded compression joint of copper wire in the harness where they used 100% pressure to "bind" the wires together.... no crimp ring, no solder.
[03:00:59] <jepler> cradek: the shape information will just treat some kinds of compensated curves as causing gouging, right?
[03:01:20] <cradek> yes I think so
[03:01:29] <jmkasunich> so, you think you can make axis show the tool shape instead of just a cone?
[03:01:31] <cradek> also there's the tool origin offsets that I was talking about today
[03:01:41] <cradek> jmkasunich: definitely
[03:01:58] <cradek> jmkasunich: SMOP :-)
[03:02:07] <jepler> cradek: while you're changing the tool table you should add enough extra columns so axis can show the mill tools right too
[03:02:23] <cradek> for mills I kept compatibility with the old tool table format
[03:02:34] <jmkasunich> diameter and length, right?
[03:02:38] <jepler> I'm sqrt(2)/3 serious
[03:03:10] <jmkasunich> what more does axis need? (I guess you might want to say "ball mill" or "end mill" or even "tapered 22.5 degrees"
[03:03:11] <cradek> jmkasunich: yes, and FMS, whatever that is
[03:03:28] <cradek> jmkasunich: I think that's exactly what he means
[03:03:31] <jepler> I should just provide a way to load a 3d model of the tool
[03:03:57] <jepler> goodnight guys
[03:04:02] <cradek> goodnight
[03:04:03] <jmkasunich> goodnight
[03:04:13] <jepler> cradek: very cool work .. when do I take you out for your beeer?
[03:04:28] <jepler> cradek: or maybe not until you finish that lathe
[03:04:31] <cradek> not sure... soon
[03:04:33] <cradek> uh-oh
[03:04:43] <jmkasunich> what is left to do on the lathe?
[03:04:55] <cradek> all the mechanical stuff
[03:05:02] <jmkasunich> motor mounts and such?
[03:05:06] <cradek> yes
[03:05:10] <jmkasunich> you're going servo, right?
[03:05:13] <cradek> yes
[03:05:20] <jmkasunich> got the pulleys and belts?
[03:05:23] <cradek> yes
[03:05:32] <jmkasunich> whacha waiting for then?
[03:05:45] <cradek> me
[03:05:54] <jmkasunich> I know how that goes
[03:06:06] <cradek> I guess I felt like programming instead
[03:06:29] <jmkasunich> thats what happened to me - now its three years later and my conversion project is still stalled
[03:06:49] <cradek> I hope mine doesn't stall that long!
[03:07:06] <jmkasunich> probalby won't, your lathe is smaller
[03:07:39] <cradek> I have a feeling I'll really want a tool changer next
[03:07:47] <jmkasunich> for the lathe?
[03:07:54] <cradek> yes
[03:07:58] <jmkasunich> fancy
[03:08:06] <cradek> the rotating changer on that overpriced lathe at workshop was pretty inspiring
[03:08:17] <jmkasunich> what about a QC toolpost and "pause" in the g-code?
[03:08:27] <cradek> that would definitely work too
[03:08:45] <cradek> don't know if they can be bought that small, maybe I would have to make it somehow
[03:08:52] <jmkasunich> one problem I have with toolposts and tool changers is that they take up space
[03:09:12] <cradek> a QC might not be that much bigger than what's on there
[03:10:21] <jmkasunich> the smallest standard QC is about 2" square without a toolholder on it
[03:10:28] <jmkasunich> the holder adds another 3/4 or so
[03:10:30] <cradek> http://www.mikestools.com/2250-Sherline-Quick-Change-Tool-Post-And-Holders.aspx
[03:11:21] <cradek> looks nice but expensive
[03:11:32] <jmkasunich> yeah
[03:11:41] <jmkasunich> can't tell what size it actually is
[03:12:02] <cradek> they say it's the sherline parting tool
[03:12:17] <cradek> so the holder is largeish
[03:12:33] <cradek> I bet it is 2"
[03:13:27] <cradek> http://www.sherline.com/images/2250fig1.gif
[03:13:36] <cradek> this gives a really good idea of the size
[03:13:40] <jmkasunich> http://www.littlemachineshop.com/products/product_view.php?ProductID=2477
[03:13:46] <jmkasunich> much cheaper
[03:14:21] <cradek> ah!
[03:15:09] <jmkasunich> http://www.littlemachineshop.com/products/product_view.php?ProductID=1147
[03:15:13] <jmkasunich> another design
[03:15:37] <jmkasunich> I bet that one could be re-designed to be much narrower
[03:15:57] <jmkasunich> it uses a t-nut kind of thing to pull the tool onto the block
[03:16:21] <jmkasunich> you could probalby make the block half as wide, and fasten it to the table with two screws that straddle the tee-nut screw
[03:16:57] <jmkasunich> http://www.littlemachineshop.com/products/product_view.php?ProductID=2401
[03:17:05] <jmkasunich> this is pretty much what I have
[03:18:21] <cradek> that $75 sherline setup looks very nice
[03:18:35] <cradek> I don't currently have any way to mount a round boring bar
[03:19:02] <jmkasunich> round boring bars are great
[03:19:12] <cradek> yeah I bet they fit in round holes better
[03:19:18] <Jymmm> lol
[03:19:26] <jmkasunich> I've made small ones from endmills
[03:19:38] <cradek> cool, that's a good idea
[03:19:43] <jmkasunich> chip one flute of a 2 or 4 flute endmill and its no good for milling
[03:19:55] <cradek> (I keep all my broken tools too)
[03:19:59] <jmkasunich> but grind off all but one flute and you have a boring bar
[03:20:18] <cradek> a nice one too
[03:20:21] <cradek> I'll remember that
[03:20:33] <jmkasunich> I also have some real 3/4" shank bars with reduced tips that can bore down to about 1/2"
[03:21:06] <jmkasunich> and a homemade one that is 3/4" diameter x 6" long and accepts a short piece of 3/16" square HSS
[03:21:31] <jmkasunich> that one is for holes over about 1"
[03:21:36] <cradek> I doubt I've ever bored anything 6" deep
[03:22:41] <jmkasunich> actually its 8" long, but with 3" in the toolholder, max depth is 5"
[03:22:55] <jmkasunich> not sure what the deepest I've bored is
[03:23:16] <jmkasunich> the bore for the worm in the gearbox has got to be up there
[03:23:27] <jmkasunich> maybe 3.5 or 4" deep
[03:24:30] <jmkasunich> diameter is only a hair over 5/8 tho, that bore is a fight with chatter
[03:24:50] <cradek> yeah that's really deep then
[03:25:28] <jmkasunich> http://www.metalworking.com/DropBox/_2001_retired_files/Worm02.jpg
[03:25:36] <jmkasunich> you can see the bore in that pic
[03:25:56] <jmkasunich> I bore it from the left side (large dia for the first bearing, then straight thru the rest of the way
[03:26:29] <cradek> what's the tolerance on the small part?
[03:26:32] <jmkasunich> the OD of the gear is 1.99", so I'm guessing the block is about 3.5 wide (drawing is on the doze PC)
[03:26:43] <jmkasunich> slip fit for the bearing
[03:27:01] <jmkasunich> I aim for plus 0.001, minus nothing
[03:27:21] <jmkasunich> the big (left) bearing takes the thrust
[03:27:41] <cradek> your lathe is big enough to hold a 3.5" block in a 4-jaw?
[03:28:07] <jmkasunich> shoptasks (like most 3-in-1's) have a large swing
[03:28:15] <cradek> I always forget people's machines are all bigger than mine
[03:28:47] <jmkasunich> something like 16" over the ways, 8" over the table
[03:28:47] <cradek> actually I could do that on the 6" if the jaws don't stick out much
[03:29:00] <cradek> wow that is big
[03:30:33] <jmkasunich> I honestly don't remember if I turn that gearbox housing in the 4-jaw or on the faceplate
[03:30:42] <jmkasunich> its been a couple years since the last time I made one
[03:31:14] <jmkasunich> pain in the ass to machine
[03:31:34] <jmkasunich> first bolt all the pieces together, drill and ream for down pins
[03:31:51] <jmkasunich> then drill for the bolts that hold it together
[03:32:15] <jmkasunich> then put it in the lathe, drill and bore the hold for the leadscrew/gear
[03:32:39] <jmkasunich> take it apart, put it back in the lathe, and bore the larger diameter steps for the gear and thrust bearings
[03:32:54] <jmkasunich> then put it back together, turn it 90 degrees, and bore the hole for the worm
[03:33:16] <jmkasunich> damn I can't spell for shite
[03:33:27] <jmkasunich> "down pins" = "dowel pins"
[03:33:31] <cradek> heh, close enough
[03:33:34] <jmkasunich> "bore the hold" ;-)
[03:33:41] <cradek> boar the whole
[03:34:21] <jmkasunich> http://www.metalworking.com/DropBox/_2001_retired_files/Worm04.jpg is the best view of all the pieces
[03:34:34] <cradek> woo
[03:34:40] <jmkasunich> shiny ;-)
[03:34:53] <cradek> very nice finish on everything
[03:34:58] <cradek> you make the crank too?
[03:35:09] <jmkasunich> I wised up since I made the first one - $25 to McMaster gets me a pre-made crank
[03:35:15] <cradek> ha
[03:35:18] <jmkasunich> (the crank in the pic I made)
[03:35:26] <cradek> the knob is a nice touch
[03:35:43] <jmkasunich> I also buy the shaft coupling (again, the pic has a home-made one)
[03:36:17] <jmkasunich> the mcmaster crank is even nicer
[03:36:41] <jmkasunich> it has a knob, and the OD of the wheel is knurled
[03:36:59] <jmkasunich> I've never tried knurling...
[03:37:23] <cradek> it usually works fine in only a few tries
[03:37:36] <cradek> :-/
[03:37:40] <cradek> (I've had mixed success)
[03:38:02] <Jymmm> Actually, kinda cool... http://led.linear1.org/led.wiz
[03:38:05] <cradek> I bet such a big diameter would be a challenge
[03:38:30] <jmkasunich> yeah
[03:38:40] <jmkasunich> I'm quite happy letting McMaster do it for me ;-)
[03:38:52] <cradek> you'd be pretty committed by the time you could tell if your knurl was going to line up
[03:38:56] <jmkasunich> shame I can't buy the gear (or the whold gearbox)
[03:39:03] <jmkasunich> whole
[03:39:51] <cradek> that couldn't be any fun
[03:39:56] <cradek> (or profit)
[03:40:23] <jmkasunich> I bet it takes me 30 hours to make that gear and box, maybe more
[03:40:41] <cradek> I'm not surprised
[03:40:57] <jmkasunich> if I could buy it for $200 I'd do it in a flash
[03:40:58] <cradek> it's easy to use an hour to bore a hole
[03:42:07] <jmkasunich> I probably have 8-10 hours in the two gear/screw assemblies already
[03:43:53] <jmkasunich> cut gear blank, face one side, drill, bore, tap (tappings a bitch), cut screw to length, clean up ends, turn down first 3/4" to 3/8 dia, thread gear onto screw and locktite, then pin, cut 5/8 sleeve to length, face both ends, drill/ream, and press onto screw
[03:44:24] <jmkasunich> then face both sides of gear blank, put steps on it to center the thrust washers, turn the OD (where I am now)
[03:44:28] <jmkasunich> turn the throat
[03:44:46] <jmkasunich> then gash teeth, hob, and spend a hour deburring
[03:45:01] <cradek> how many hours (if any) would cnc save you on this job?
[03:45:09] <jmkasunich> hard to say
[03:45:27] <jmkasunich> the only thing that really screams out for CNC so far is the throat on the gear (an arc cut)
[03:46:11] <jmkasunich> there are a lot of places where CNC would let me sit and watch instead of turning the cranks
[03:46:21] <jmkasunich> but the actual cutting time wouldn't be any lower
[03:46:25] <cradek> have you every used HNC (human)? calculate the steps and dial them in?
[03:46:42] <jmkasunich> might be longer actually, doing it by hand I can push the depth and/or feed more
[03:46:52] <jmkasunich> I considered that for the throat
[03:47:02] <jmkasunich> still haven't decided what to do
[03:47:47] <cradek> HNC is in my bag of tricks but I haven't used it for a real project
[03:48:46] <jmkasunich> I rarely find myself cutting the kind of profiles where CNC (or HNC) really shines
[03:49:00] <jmkasunich> usually its a straight diameter, a step, and another diameter
[03:49:06] <jmkasunich> maybe several steps, etc
[03:49:17] <cradek> yeah CNC doesn't get you much then
[03:49:27] <cradek> unless it's an hour of slow boring
[03:49:27] <jmkasunich> diameter and depth are critical, but there aren't any curves or even tapers
[03:49:44] <jmkasunich> the limiting factor on the bulk boring is clearing chips
[03:49:56] <jmkasunich> damn things wrap around the boring bar and make a mess
[03:50:38] <jmkasunich> if I could get the chips to break it would be much quicker
[03:51:24] <jmkasunich> thats one nice thing about the worm bore (as opposed to the gear bore)... since the housing is split and I'm boring along the split line, there is a natural break in the chip every 180 degrees
[03:51:29] <cradek> at least it's not chattering if you get those long chips
[03:51:49] <jmkasunich> oh, I can get chatter and long chips at the same time :-(
[03:51:59] <cradek> haha
[03:53:40] <cradek> http://www.metalworking.com/DropBox/_2001_retired_files/untwisted.jpg
[03:54:04] <jmkasunich> chinese drill bits
[03:54:25] <jmkasunich> HSS... not!
[03:54:51] <cradek> costs you a drill bit AND your work
[03:55:30] <Jymmm> jmkasunich No, they are HSS... Hunk of Shit Steel
[03:55:42] <jmkasunich> chinese cheddar cheese steel
[03:55:47] <jmkasunich> http://www.metalworking.com/DropBox/_2001_retired_files/Facemil3.jpg
[03:55:54] <jmkasunich> this is what I'll be doing in a few weeks
[03:56:23] <cradek> that's quite the tool
[03:56:46] <jmkasunich> actually I'm a little bummed - I have 4 pieces of 3/4" and 8 pieces of 1/2" to do, so I'll need two stacks
[03:56:52] <jmkasunich> twice as much time
[03:57:05] <jmkasunich> that tool cost me all of $10
[03:57:12] <jmkasunich> at the $2/lb sale
[03:57:23] <jmkasunich> 5-1/2" diameter, 12 teeth, it moves some metal
[03:58:09] <jmkasunich> I've gone as deep as 0.250 while cutting nearly full width (that pic is probably between 0.050 and 0.100 deep)
[03:58:42] <jmkasunich> I've also cut 5/8" deep x 1" wide in one pass with it
[03:58:54] <cradek> jeez
[03:59:09] <jmkasunich> see pic 4
[03:59:26] <jmkasunich> the chips go "clink" when they hit the floor ;-)
[03:59:48] <cradek> fun
[03:59:52] <jmkasunich> yeah
[04:00:28] <jmkasunich> what sucks is that it takes me longer to break the sharp 90 degree corners on the plates than it did to mill them
[04:01:18] <jmkasunich> 12 plates, each has 8 long edges, 4 short edges, and 8 corners......
[04:02:42] <jmkasunich> I wonder if a router table, and a chamfer bit with a ball bearing pilot
[04:02:57] <jmkasunich> still probably leave a burr
[04:04:33] <jmkasunich> heh, they really stretch the meaning of the word "portable" http://www.metalworking.com/DropBox/_2001_retired_files/facemill96.jpg
[04:05:21] <cradek> yep
[04:05:34] <cradek> I agree it would be possible to move it from one place to another
[04:05:54] <jmkasunich> I remember when all those pics got posted.. we were having "facemill wars" - one-upmanship
[04:06:08] <jmkasunich> started with a 2" one http://www.metalworking.com/DropBox/_2001_retired_files/facemill1.jpg
[04:06:16] <jmkasunich> then mine
[04:06:18] <jmkasunich> then this one
[04:06:26] <jmkasunich> http://www.metalworking.com/DropBox/_2001_retired_files/Face_mill1.jpg
[04:06:43] <jmkasunich> then finally the 96" one... everybody pretty much shut up after that
[04:07:16] <Jymmm> wth is that last pic?
[04:07:30] <jmkasunich> about a 12" face mill
[04:07:46] <Jymmm> fuck me!
[04:07:57] <jmkasunich> no thanks, you're not my type
[04:08:13] <Jymmm> what do you use that on?
[04:08:25] <jmkasunich> things that need to be flat
[04:08:35] <Jymmm> heh, no I mean surely not a BP
[04:08:42] <roltek> jmk what type of gear are you trying to cut
[04:08:47] <jmkasunich> no, not a BP
[04:09:00] <jmkasunich> big old cincinati horizontal or something like that
[04:09:03] <jmkasunich> roltek: worm gear
[04:09:33] <roltek> pitch,preasure angle
[04:09:39] <jmkasunich> http://www.metalworking.com/DropBox/_2001_retired_files/Worm04.jpg
[04:09:58] <jmkasunich> I'm using 5/8 - 5tpi acme threaded rod as the worm
[04:10:04] <jmkasunich> so pressure angle is whatever it is
[04:10:59] <jmkasunich> http://home.att.net/~jmkasunich/Pics/KE01052109.pdf is the drawing, it has some of the specs
[04:11:00] <roltek> i have hobs but think i can help you with that
[04:11:16] <jmkasunich> I only have to make 2 of them
[04:11:26] <jmkasunich> I've done it before, have all the tooling already
[04:11:35] <roltek> ok
[04:12:02] <jmkasunich> if you look at higher numbered pics (worm05.jpg thru worm09.jpg) you'll see my tooling and setup
[04:12:55] <jmkasunich> 5 & 6 are tooling, 7 & 8 are gashing, 9 & 10 are hobbing (free hobbing)
[04:14:43] <jmkasunich> pretty much amateur hour compared to the kind of work you do ;-)
[04:15:37] <roltek> not really just another way to skin a cat
[04:15:49] <jmkasunich> the slow way
[04:16:23] <roltek> you do with what you have
[04:17:29] <roltek> when your gashing worm wheels , i take it your indexing your gear so you will have to be concerned with indexing error
[04:17:54] <jmkasunich> I'm using a dividing head, if thats what you mean by indexing
[04:18:02] <roltek> yes
[04:18:16] <jmkasunich> IOW, don't fsck up the cranking...
[04:18:41] <jmkasunich> the arms really help there, but you still gotta remember to do everything the right way
[04:19:04] <jmkasunich> turn the arms, pull the pin, turn the handle N turns, then continue till it gets to the arm
[04:19:25] <roltek> i have a ? on your encoder ratio hal mod
[04:19:34] <jmkasunich> ok, shoot
[04:20:25] <roltek> can i hook more than 1 axis up at a time to follow master
[04:20:30] <jmkasunich> sure
[04:20:41] <jmkasunich> just use more than one encoder ratio component
[04:20:57] <jmkasunich> you can route the master encoder signals to as many components as you want
[04:21:47] <roltek> was there any correction factors built in for counting of steps and slowwing down or speeding up
[04:21:57] <jmkasunich> the main limitation will either be having enough inputs for the encoder signals, or running out of speed (this is a software encoder counter)
[04:22:12] <jmkasunich> not sure I follow you
[04:22:33] <jmkasunich> the intent was that the master encoder signal goes to one input, the slave encoder goes to the other, and the output is position (tracking) error
[04:22:44] <jmkasunich> send the error to the PID to close the loop
[04:23:01] <jmkasunich> if the master speeds up or slows down the slave does the same
[04:23:18] <roltek> some of electronic gear box's i have seen or egb will have counting correction's
[04:23:44] <jmkasunich> guess I don't know what they are correcting for
[04:25:01] <roltek> i am not sure but will find out more
[04:25:35] <jmkasunich> if its something that is needed, and you can explain it in a way I understand, I can probably add it
[04:25:51] <roltek> great
[04:26:11] <roltek> i have to do more studying on egb
[04:27:06] <roltek> i do know that they use phase lock looping
[04:29:45] <roltek> see you guy's later
[04:30:05] <jmkasunich> goodnight
[04:53:41] <Jymmm> man, solding just kills my back!
[04:53:45] <Jymmm> soldering
[04:54:06] <jmkasunich> need a better bench layout
[04:54:31] <Jymmm> yeah, and a 3rd hand wouldn't hurt much either
[04:56:39] <Jymmm> but when your soldering bench is also your buffing/snading/saw bench, it makes it difficult at times =)
[04:57:04] <jmkasunich> 3rd hand like this: http://www.rjsintl.com/productListing.asp?category=Soldering&cat1=Tools&cat2=Third+Hand
[04:58:17] <Jymmm> I was thinking more like this, but I guess that'll do =) http://elfwood.lysator.liu.se/farp/hand/Untitled-28.JPG
[04:59:35] <Jymmm> What I'll end up doing is just making a fixture instead
[05:00:13] <Jymmm> Hey, have you used a wire wrap GUN before?
[05:00:35] <jmkasunich> a long time ago, and not very much
[05:00:59] <Jymmm> do yo remember if it automatically strips the wire too?
[05:01:23] <jmkasunich> I don't think it does
[05:01:42] <Jymmm> do you think ANY of them might?
[05:01:49] <jmkasunich> no clue
[05:02:00] <jmkasunich> I haven't done any wire-wrapping in maybe 10 years
[05:02:04] <Jymmm> heh, me neither. I have a manual tool.
[05:35:10] <giacus> G morning
[05:36:49] <giacus> wake up gents :D
[05:36:54] <giacus> ZZzzZZZzZzz
[07:32:54] <Lerneaen_Hydra> hi
[07:33:45] <A-L-P-H-A> ho
[07:50:34] <Jymmm> Can anyone think of a "reasonable" way to hold a 9V battery in a pocket that doens't require any tools to replace the battery? The only thing I could think of was using a brass disc that would rotate over the battery itself (bent slightly to hold the battery snag).
[07:50:47] <Jymmm> snug
[07:52:14] <giacus> hellooo
[07:52:25] <giacus> good morning
[07:53:36] <Jymmm> Mornin Jacky
[07:55:50] <giacus> Jymmm: is it correct "Thanks to Giacus for share this video." ?
[07:56:06] <giacus> or "Thanks to Giacus for sharing this video." ?
[07:56:16] <Jymmm> the 2nd one
[07:56:20] <giacus> ty
[07:56:25] <Jymmm> np
[08:04:54] <alex_joni> 'lo guys
[08:05:08] <Jymmm> lo
[08:06:55] <alex_joni> I should probably get going to work :)
[08:07:06] <Jymmm> only if you like to eat =)
[08:07:20] <alex_joni> well, I already ate
[08:07:29] <alex_joni> :-P
[08:07:34] <Jymmm> and sleep under a roof
[08:08:08] <alex_joni> well... I just woke up, and it seems I'm under a roof :P
[08:08:21] <Jymmm> not if you dont pay the rent
[08:08:57] <alex_joni> over here it's not really custom to pay rent
[08:09:06] <alex_joni> most people kinda own their places
[08:09:36] <fenn> as it should be
[08:09:40] <giacus> hello alex
[08:09:44] <giacus> hi fenn
[08:10:11] <giacus> nobody seems to sleep much in these days
[08:10:28] <Jymmm> WE can sleep all we want when we're dead
[08:11:36] <giacus> I had a battle with mosquitos latest night
[08:11:43] <Jymmm> garlic
[08:11:46] <giacus> wake up at 6:00
[08:14:36] <giacus> there's a new sort of tropical mosquitos here since some year
[08:14:44] <giacus> called mosquito tiger
[08:15:04] <giacus> they looks like condors
[08:15:20] <giacus> eat garlic for snack
[08:16:12] <Jymmm> giacus: http://www.mosquitobarrier.com/
[08:16:23] <giacus> http://www.comune.torino.it/ucstampa/2004/article_562.shtml
[08:16:30] <Jymmm> No, make a garlic concentrate an d spray around windows, doors, house, etc.
[08:17:03] <alex_joni> lol
[08:17:19] <giacus> yes, I need something like that
[08:17:47] <alex_joni> giacus: how bad is it over there?
[08:18:12] <giacus> alex_joni: for ?
[08:18:13] <alex_joni> with the mosquitos I mean
[08:18:19] <alex_joni> * alex_joni is thinking about sicily :D
[08:18:28] <alex_joni> should I pack tons of spray?
[08:19:02] <giacus> no, you can find all there around
[08:19:17] <giacus> the better I know is called Vape magic
[08:19:22] <giacus> its weird
[08:20:01] <Jymmm> giacus Make some garlic oil, but dont use a vegetable oil that will go rancid on you
[08:20:16] <giacus> mosquitos become very aggressive especially with peoples that comes from places far away
[08:21:30] <giacus> it seems they are able to understand the difference of skin
[08:21:33] <Jymmm> giacus: To make garlic oil, use LOW heat
[08:21:39] <alex_joni> heh
[08:21:46] <giacus> Jymmm: I'll try
[08:21:49] <alex_joni> ok.. later guys
[08:22:19] <Jymmm> laters alex_joni
[08:22:21] <giacus> later alex
[08:28:14] <bullzebub> hello everyone
[08:28:59] <bullzebub> regarding the "dapper" problems of installing EMC... do they extend to compiling the source too?
[08:29:46] <Lerneaen_Hydra> how do you mean?
[08:30:01] <Lerneaen_Hydra> just compiling the source won't help
[08:30:50] <Lerneaen_Hydra> AFAIK it's the RT kernel that's causing the issues, but you'd better ask someone that knows about that better (cradek, alex_joni, and several others. check #emc-devel)
[08:31:36] <bullzebub> RT?
[08:33:05] <alex_joni> bullzebub: realtime
[08:33:14] <alex_joni> emc needs realtime extensions in the linux kernel
[08:33:33] <bullzebub> Ah ... thnx :-)
[08:33:33] <alex_joni> because it needs certain parts of it to work very fast (every few microseconds)
[09:09:35] <Lerneaen_Hydra_> Lerneaen_Hydra_ is now known as Lerneaen_Hydra
[10:25:47] <Lerneaen_Hydra2> hello?
[10:25:51] <Lerneaen_Hydra2> anyone here?
[10:29:22] <anonimasu> yes
[10:30:23] <Lerneaen_Hydra2> do you know anything about emc & dapper?
[10:30:27] <anonimasu> no
[10:30:48] <Lerneaen_Hydra2> ok, I'll wait untill alex or someone else who knows comes
[10:32:36] <Lerneaen_Hydra2> * Lerneaen_Hydra2 pokes alex_joni
[10:49:21] <Lerneaen_Hydra2> http://emc.pastebin.com/728667 <- this is the second time I run the script, the first time I didn't run it in a terminal and it silently died
[10:54:03] <Lerneaen_Hydra2> http://emc.pastebin.com/728671 <- the modified script I ran
[11:06:52] <fenn> heh emc.pastebin.com
[11:07:28] <fenn> unfortunately it seems to take forever to load
[11:07:49] <Lerneaen_Hydra2> yes, it did for me too
[11:07:58] <fenn> just use regular pastebin then
[11:08:00] <Lerneaen_Hydra2> for some reason, even though AFAIK it's on the same server
[11:10:51] <Lerneaen_Hydra2> hmm, pastebin seems to be very slow to upload
[11:11:11] <Lerneaen_Hydra2> ok if I flood?
[11:12:11] <fenn> blast away
[11:12:32] <Lerneaen_Hydra2> gksudo -m "Enter your password to install EMC2" true

[11:17:39] <alex_joni> Lerneaen_Hydra2: you need Universe
[11:17:53] <alex_joni> because bwidget is there
[11:22:47] <Lerneaen_Hydra> oh
[11:22:52] <Lerneaen_Hydra> I forgot to add them
[11:22:59] <Lerneaen_Hydra> universe multivers
[11:23:06] <alex_joni> universe is enough
[11:23:08] <Lerneaen_Hydra> I'll test that soon
[11:41:06] <alex_joni> ok
[11:50:23] <Lerneaen_Hydra> ooh. 2.0.1 works nicely
[11:50:28] <Lerneaen_Hydra> or at least, sim does
[11:50:39] <Lerneaen_Hydra> anyway, I'll test cvs later today or tomorrow
[11:55:05] <alex_joni> cool, so except the bwidget there was no other problem?
[13:22:23] <Bo^Dick> could someone suggest a good way of adding trim-pots to this design so i can trim the lowest and highest voltage from this voltage regulator application? http://www.carmi.se/misterstarshine/img/4.gif
[13:23:30] <Bo^Dick> right now naturally it swings between -0.1 volts and 18.7 volts
[13:23:41] <Bo^Dick> i'd like to have between 0 and 15 volts
[13:24:14] <Bo^Dick> is there a clever way to do this?
[13:25:10] <SWP_Away> add trim pots above and below Rvar, so you have 3 in series instead of only one
[13:25:56] <SWP_Away> oops - one needs to be in parallel, one in series
[13:26:25] <SWP_Away> turn Rvar all the way down, and adjustthe series trim pot so you get the lowest voltage you want
[13:26:46] <SWP_Away> turn Rvar all the way up, and adjust the parallel trim pot for the highest voltage you want
[13:27:00] <CIA-8> 03jepler 07HEAD * 10emc2/src/hal/utils/scope_disp.c: draw the baseline for the samples even when there are no samples
[13:40:10] <Bo^Dick> the trimmed minimum output voltage seems to be incredibly sensitive to which mode on the multimeter i choose
[13:40:55] <Bo^Dick> on the 1000 VDC it says the minimum val is 11 volts and on the 200 volts mode it says 2 volts all the way down to the 200mV mode where it shows zero
[13:41:29] <Bo^Dick> i thought the output impedance of a multimeter in voltage mode was high
[13:41:46] <SWP_Away> the input impedance should be around 1 or 10 megohm
[13:41:52] <alex_jon1> alex_jon1 is now known as alex_joni
[13:41:58] <SWP_Away> SWP_Away is now known as SWPadnos
[13:43:28] <Bo^Dick> it is 1 megaohm on all modes
[13:43:55] <Bo^Dick> and the voltage value shows different for each mode. this is totally whacked up!
[13:45:10] <SWPadnos> is it a crappy meter?
[13:45:46] <SWPadnos> I suppose I should rephrase that - it
[13:45:50] <Bo^Dick> i don't know. but it should'nt be this bat
[13:45:55] <SWPadnos> it's probably a crappy meter
[13:46:23] <Bo^Dick> the output voltage doesn't seem to be very stable either
[13:46:34] <Bo^Dick> it's flickering around all over the place
[13:46:39] <SWPadnos> remember - the meter has the same input voltage range and resolution, regardless of the range setting. there are just resistor dividers put in front of the A/D
[13:47:02] <Bo^Dick> gotta look at the output on the scope i think
[13:47:08] <SWPadnos> so small amounts of noise will look like large voltages in the 200V range
[13:47:10] <SWPadnos> yep
[13:47:18] <SWPadnos> set the meter for AC, and see what happens
[13:51:42] <Bo^Dick> i've looked at the output voltage on the osc.scope and there is hardly any ripple or noise at all
[13:54:13] <SWPadnos> hook up the meter and the scope, and see if there are any major changes when you switch meter ranges
[14:04:41] <Bo^Dick> i'm now testing with two multimeters, one is newer than the other and possibly more reliable
[14:05:11] <Bo^Dick> the other multimeter shows 20 volts on the 600V mode and 10 volts when in 200V mode
[14:06:20] <SWPadnos> and what does mr. o-scope say?
[14:06:21] <Bo^Dick> it didn't do that when i was trying it with a 9V battery
[14:06:56] <Bo^Dick> o-scope doesn't show a lot of ripple but these strange behaviour must be due to ripple
[14:08:22] <Bo^Dick> lets zoom in the ripple real good!
[14:10:09] <Bo^Dick> as a matter of fact, it looks like the ripple exceeds 0.2 volts in magnitude!
[14:10:35] <Bo^Dick> but how can the multimeter read 20 volts on 10 volts
[14:15:53] <Bo^Dick> the signal looks awful
[14:16:20] <Bo^Dick> there is a low frequency sawtooth overloaded and a 100MHz signal with 0.2V magnitude p-p
[14:21:50] <Bo^Dick> my 1000µF smoothing caps appears highly inadequate for the task :(
[14:23:21] <Bo^Dick> one can hardly obtain ripple-free 1 amps current from a 1000µF smoothing cap
[14:24:43] <Bo^Dick> i seriously need some monster caps
[14:25:28] <Bo^Dick> this explained the saw-tooth shaped ripple on my output signal but it does not explain the aggressive 100MHz signal with 0.2V p-p
[14:45:45] <Bo^Dick> could someone refresh my memory regarding smoothing caps for power supplies as a function of the load current drawn
[14:46:52] <ottos> hello gents..
[14:58:01] <fenn> Bo^Dick: a 1000uF cap probably won't take out a 100mhz signal, you need to add some smaller bypass caps
[14:58:13] <fenn> but.. where the heck is a 100mhz signal coming from?
[14:58:35] <SWPadnos> it's probably from a nearby radio station
[14:58:52] <fenn> they have radio stations in sweden? :)
[14:59:03] <SWPadnos> oh right - maybe not ;)
[14:59:53] <Bo^Dick> the 100MHz signal puzzles me
[15:01:20] <Bo^Dick> first of all i need to recall to that formula that calculated the needed smoothing capacitance as a function of the desired current to be drawn
[15:01:39] <SWPadnos> dv/dt = I/C
[15:02:30] <Bo^Dick> if i remember correctly the formula also incorporated the ripple level which in my case shouldn't be larger than 0.5 volts max
[15:02:39] <Bo^Dick> at 1 amp that is
[15:03:25] <SWPadnos> are you on 50 Hz or 60 Hz?
[15:03:59] <Bo^Dick> 50Hz
[15:04:21] <SWPadnos> ok, so assuming that the ripple is from line frequency (possibly a bad assumption):
[15:04:37] <SWPadnos> dt = 0.01 second
[15:04:51] <SWPadnos> dv = 0.5V (specified by you)
[15:04:54] <Bo^Dick> i'm only talking about that ripple now, not about the 100MHz noise
[15:04:59] <SWPadnos> I = 1A (specified by you)
[15:05:06] <Bo^Dick> SWPadnos: yeah
[15:05:17] <SWPadnos> .5/0.01 = 1/C
[15:06:37] <Bo^Dick> C=0.02 F
[15:06:49] <SWPadnos> yep (left as an exercise for the reader)
[15:06:55] <Bo^Dick> or 200000µF
[15:07:01] <Bo^Dick> that's a monster cap!
[15:07:14] <SWPadnos> you havea n extra zero in there
[15:07:22] <SWPadnos> 20,000 uF
[15:07:42] <fenn> could be worse
[15:07:43] <Bo^Dick> ok
[15:08:16] <fenn> time to re-assume some assumptions
[15:54:43] <dmessier> Hello all
[16:23:55] <dmessier> alpha around??
[17:07:50] <giacus> alex_joni: you there ?
[17:08:47] <alex_joni> yes
[17:08:51] <giacus> I lost the url of your videoclip (my toy) :(
[17:09:01] <alex_joni> dsplabs.cs.utt.ro/~juve/emc/mytoy
[17:09:20] <giacus> alex how could be named that ?
[17:09:29] <alex_joni> tripod ;)
[17:09:33] <giacus> Ok
[17:09:35] <giacus> thanks
[17:11:21] <giacus> was running with emc2 I suppose
[17:11:59] <alex_joni> yes
[17:12:03] <giacus> just to be sure :)
[17:42:13] <Dallur> Is Anders Wallin here ? Or does someone know if he comes by here ?
[17:49:37] <jmkasunich> I don't recall ever seeing him here (at least not by a name that I recognize)
[17:53:40] <Dallur> jmkasunich: Thanks, I got an email from him and thought he might use IRC to, I will just drop him a mail .. thanks
[18:08:44] <cradek> he does use irc, but I forget the name he uses
[18:11:43] <cradek> 'etla'
[18:14:13] <Dallur> great, thanks :D
[18:20:44] <Dallur> Does anyone know of a way to dynamically adjust classicladder timers/monostables ? I was hoping to make configurable timers through VCP when float support is available :D
[18:33:38] <dmessier> what dos emulator can i throw at ubuntu??
[18:33:53] <jmkasunich> I don't think that's doable (without major hacking on classicladder)
[18:34:07] <Dallur> isn't there a wine package for ubuntu ?
[18:35:12] <jmkasunich> Dallur: if you need timers who's delay is adjusted by a HAL signal, I could probably write such a hal component
[18:35:21] <jmkasunich> that seems like a hack tho
[18:35:30] <jmkasunich> the classicladder timers are already there
[18:35:41] <Dallur> jmkasunich: Yup, I think it would make sense to do it with classicladder
[18:35:52] <Dallur> jmkasunich: I think I might have found some ref. to a T[...] variable but I still have no way to pass float/int to classicladder, I'm going to poke around a bit more
[18:36:03] <jmkasunich> the problem is that we don' t have anyone who really understands classicladder
[18:36:13] <jmkasunich> (with the possible exception of petev)
[18:36:44] <jmkasunich> what kind of granularity are you looking for?
[18:37:00] <jmkasunich> today, CL limits you to 100mS, even tho the code is running every 1mS
[18:37:11] <jmkasunich> (an artifact of CL's original, non-RT design)
[18:37:14] <Dallur> yup, which is fine for what I am doing
[18:37:35] <Dallur> I have a pierce delay timer which really should be adjustable for sections of different thickness
[18:38:08] <Dallur> and I have a timer which triggers an estop if an arc is not established within a given period from the torch being turned on
[18:38:46] <Dallur> 100ms is just right for the pierce delay and more than good enough for the estop timer
[18:39:11] <cradek> dmessier: I use qemu with freedos, there's also a free (free as in money) vmware now
[18:39:51] <cradek> dmessier: the vmware is a little more challenging to install, but it runs faster
[18:42:17] <dmessier> qemu??
[18:42:27] <cradek> ?
[18:43:16] <Dallur> dmessier: I highly recommend -> http://www.winehq.org/site/download-deb, I use it at work when I have to run IE on my laptop to test IE only web stuff
[18:43:50] <cradek> I think wine does not run dos
[18:43:55] <Dallur> dmessier: although I run Centos on my laptop :D
[18:44:10] <cradek> if you have a real copy of dos (or freedos) you want to run, you need a machine emulator, like qemu or vmware
[18:44:47] <Dallur> cradek: It is true that it will not run dos but it emulates dos and as such you can run almost any win32 application on it
[18:44:51] <jmkasunich> Dallur: how well does wine work these days?
[18:44:55] <dmessier> ahh i see... does freedos let you set dos version??
[18:45:04] <cradek> dmessier: not sure
[18:45:06] <jmkasunich> I tried it once, long ago, and gave up in frustration
[18:45:21] <dmessier> i need an old dos ver..
[18:45:33] <jmkasunich> I want to run a doze CAD program, easycad, on my linux box
[18:45:38] <dmessier> tryin' to resurect a postprocessor..
[18:45:39] <cradek> I've tried wine on and off for many years, never seemed quite good enough to be useful
[18:45:49] <cradek> dmessier: why does it depend on dos version?
[18:46:05] <cradek> I bet wine is good now, it's a very old app
[18:46:06] <dmessier> locked in the code SOMEWHERE..
[18:46:22] <cradek> dmessier: that's nuts
[18:46:29] <jmkasunich> fine wine improves with age?
[18:46:39] <dmessier> comes up tith incorrect dos version error
[18:46:47] <Dallur> cradek: it is pretty decent by now, runs the entire office suite, IE and almost anything I have thrown at it, hmm I think I need to try Mach3 just for fun one of these days :D
[18:46:58] <cradek> Dallur: that's nice to know
[18:47:14] <cradek> Dallur: it doesn't require you own a windows license, which is a big advantage I think
[18:47:49] <jmkasunich> windows license? whats that?
[18:48:01] <jmkasunich> (I run w95 on the one remaining doze box I have)
[18:48:15] <Dallur> jmkasunich: it is like a tax on every computer sold that goes to a company in seattle so they can spy on you
[18:48:20] <dmessier> this post is a fill kinetic carrying post that eats apt cl
[18:48:50] <cradek> dmessier: do you remember the name of the program that tells dos to fake versions for certain apps? I can see if mine has it, but I can't remember the name of it
[18:49:14] <dmessier> dosver
[18:50:28] <dmessier> ive tried to fake it from win2000 ,XP , 98... doesnt work... also it seemed to like a 486 best..
[18:51:11] <dmessier> dont ask... its old stuff... i did say "Resurrect"
[18:51:18] <cradek> I don't see a dosver
[18:51:48] <cradek> want to borrow my AT?
[18:52:03] <dmessier> want to try some software??
[18:52:15] <cradek> nope
[18:52:29] <cradek> actually I recently unhooked it because I needed the desk space
[18:53:33] <cradek> why not just put dos on an old 486?
[18:53:37] <dmessier> figures... EVERY ones trashin them... and NOT giving them to me... i have 1 in the basement but its a pita
[18:53:47] <cradek> or do you want to actually use this software as-is
[18:54:08] <cradek> my AT is running a recent freedos too, so it probably wouldn't work
[18:54:10] <dmessier> i would like to have it web based... send in apt get back g-code
[18:54:47] <cradek> maybe you could disassemble it enough to find the dos version check, and disable it
[18:55:02] <dmessier> you build YOUR machines post.. on this server.. and post to it... for g-code
[18:55:03] <cradek> I doubt it actually depends on a certain dos version.
[18:55:25] <dmessier> i've looked and couldnt make it out..
[18:55:38] <dmessier> me too.. but its something
[18:56:51] <dmessier> linux just seems to be the way to get the networking i need IF i can get the s/ware to run somehow
[19:00:26] <cradek> dmessier: is it just an exe? I can try to run it for you on freedos
[19:01:57] <cradek> looks like you can set VERSION in the environment
[19:03:59] <cradek> I think it's setver, not dosver
[19:17:46] <jmkasunich> cradek: thanks for suggesting HNC last night
[19:17:55] <jmkasunich> just tried it on the first gear blank, worked great
[19:18:01] <cradek> slick
[19:18:16] <jmkasunich> 0.005 steps, all I needed was a tiny bit of 500 grit to smooth it up
[19:19:00] <jmkasunich> (I was cutting a 7/16 dia curve, so I wrapped the sandpaper around a 27/64 drill bit shank, the 1/64 undersize is to make up for the paper thickness)
[19:19:22] <cradek> perfect
[19:20:02] <jmkasunich> I think the result is better than I got in the past (where I set up a crude "ball turning attachment" by mounting a tool and swiveling the compound to cut the arc
[19:20:23] <cradek> about 80 steps?
[19:20:41] <cradek> that's another creative way of doing it
[19:20:58] <jmkasunich> 0.250 to 0.500 by 0.005
[19:21:07] <jmkasunich> feeling math challenged right now...
[19:21:15] <jmkasunich> 50 steps?
[19:21:26] <cradek> yep
[19:21:51] <cradek> I guess that wouldn't take long at all
[19:22:05] <jmkasunich> much less than the setup time the old way
[19:22:21] <cradek> I don't think my compound slide is at all rigid when it's not tightened down
[19:22:41] <jmkasunich> mine isn't that rigid either, but I take light cuts
[19:23:40] <cradek> I ordered that QC
[19:23:47] <cradek> couldn't resist
[19:23:48] <jmkasunich> the $75 one?
[19:23:52] <cradek> yes
[19:24:09] <jmkasunich> it'll be interesting to see what size it actually is
[19:24:26] <jmkasunich> once you get it, let me know, I'd like to compare the dovetail measurements with mine
[19:25:02] <cradek> ok
[19:25:26] <cradek> I got a couple extra turning tool holders, so I can mount all three of my insert tools (left, center, right) and a threading tool
[19:25:37] <dmessier> we recently had a request from design engineering to make the I/D of a set of bushings spherical...
[19:25:55] <dmessier> not cylindrical
[19:25:59] <cradek> bizarre
[19:26:19] <cradek> but simple with cnc and a boring bar
[19:26:45] <dmessier> after the bushes have been installed into the main fitting... ;(
[19:27:30] <jmkasunich> just get out your spherical reamer ;-)
[19:27:33] <dmessier> d'andrea head attatchment on our new okk SHOULD handle it... but what a cluster fack of a BAD idea
[19:28:12] <jmkasunich> dumbass design engineers
[19:28:23] <anonimasu> heh
[19:28:23] <dmessier> i just DONT see the engineering theory in this one... the pin is still a cylinder..
[19:28:44] <anonimasu> heh ;)
[19:28:45] <cradek> sounds very odd
[19:29:01] <jmkasunich> spherical as in bigger in the center than the ends?
[19:29:05] <cradek> next they'll ask you how to get the sphere in there
[19:29:17] <dmessier> amd we are talking about hte main PINTLE pin that holds the L/g the the aircraft
[19:30:16] <jmkasunich> how spherical? (I mean, how much bigger in the center than the ends - a few thou, or a lot?)
[19:30:31] <dmessier> its been mentioned.... i went ballistic as did the SR. methods guy... we went of on need ing gravity intensifiers to do it... and shite.. was a hoot..
[19:31:22] <dmessier> about .024 over a 3.5" bush from center both ways...
[19:31:42] <dmessier> and dont get to the nitro way... ive been there..
[19:31:48] <cradek> and the ID is bigger in the center?
[19:31:54] <Jymmm> Jymmm is now known as Jymm
[19:32:06] <dmessier> smaller in the center...
[19:32:12] <cradek> oh a torus shape
[19:32:14] <jmkasunich> thats not spherical then
[19:32:21] <cradek> * cradek points at jmk
[19:32:38] <jmkasunich> and I can even (maybe) understand why
[19:32:48] <jmkasunich> under heavy load, the pin is gonna bend a little
[19:32:49] <cradek> I can see a torus, it allows error in alignment
[19:33:09] <jmkasunich> in a straight bore, that will concentrate all force on the edges
[19:33:11] <dmessier> doghnut yeah.. torus connonical form torus/x,y,z,r1,r2
[19:33:30] <dmessier> 1 edge point in the center..
[19:34:01] <dmessier> but i think the plane will wiggle EVERY time it lands
[19:34:27] <jmkasunich> I bet there are other points of support
[19:34:39] <dmessier> ??
[19:34:49] <jmkasunich> words fail me...
[19:34:59] <jmkasunich> is the gear hanging from only one pin?
[19:35:07] <anonimasu> there shouldnt be a engineer that stupid alive.. not to have additional support..
[19:35:35] <dmessier> 1 pin... an actuator... and a side stay brace..
[19:35:50] <jmkasunich> the side stay brace will prevent the wiggle then
[19:36:35] <dmessier> the main pintle pin is ALL that holds MOST commercial and buisness jets l/g on
[19:36:38] <anonimasu> hm, might the donut have to do with preventing long term fatigue
[19:37:21] <dmessier> but the short ter..high stress profile in the center defeats it...
[19:38:05] <dmessier> ther will be CLEARANCE Clerance.. by the 2 landing
[19:38:52] <dmessier> the bushings are 17-4 ph at 42-26 Rc
[19:38:52] <jmkasunich> clearance when unloaded
[19:39:11] <jmkasunich> what about the pin?
[19:39:15] <jmkasunich> and what diameter is it?
[19:39:21] <dmessier> it WILL mash the highspot off the bushing i believe
[19:39:33] <dmessier> 2.05" ish
[19:42:34] <dmessier> 300m.. pre- machined....h/t...finish turned...nital etch inspect... mag particle inspect .. out for chrome and cad and another mag.. final grind on chrome...lpi of ground chrome... mag on ground chrome... final dimensional and visual insection
[19:45:11] <dmessier> lpi = liquid penetrant inspection
[19:46:57] <jmkasunich> wow
[19:47:11] <jmkasunich> they really really don't want cracks
[19:57:57] <Jymm> Can anyone think of a reasonable way to hold a 9V battery into a pocket w/o using tool to replace the battery? I was thinking of using a small disc that rotated over the battery, but I'm not sure I'll have even room to do that, I'm workign with limited space.
[19:59:29] <Jymm> I DO have side room, just not depth to play with
[20:00:37] <dmessier> cover and a zip tie glued OUtside??
[20:02:10] <jmkasunich> edges of the battery are rounded, can you make something that goes over only the edge, not the flat part?
[20:02:36] <jmkasunich> maybe one flathead screw on each side of the battery
[20:02:37] <Jymm> jmkasunich like a spring tab of sorts?
[20:02:53] <jmkasunich> the screwheads are flush with the top of the battery, but the edge of each head holds down the battery
[20:03:11] <dmessier> super glue.. no screws... ; 0
[20:03:38] <dmessier> could you mould it??
[20:03:44] <Jymm> They have to be able to change the battery, preferably without the use of tools.
[20:03:51] <dmessier> the cover..??
[20:04:22] <jmkasunich> Jymm: can you visualize the screw based design I described?
[20:04:55] <Jymm> jmkasunich The screw head overlaps the rounded part of the longest edge of the battery
[20:04:58] <dmessier> 2 slots to catch the cover on the sides...
[20:05:01] <jmkasunich> yes
[20:05:16] <jmkasunich> if you don't want screws, then do something similar with springy tabs
[20:05:35] <jmkasunich> either way, it can be effectively zero depth (other than the depth of the battery itself)
[20:05:42] <Jymm> jmkasunich I have no room on the depth of width of the battery, I DO have shitloads on the length though.
[20:05:51] <Jymm> s/of/or/
[20:06:08] <jmkasunich> a few minutes ago you said you had side room
[20:06:36] <Jymm> jmkasunich My bad... I was looking at it laying on it's edge
[20:07:03] <jmkasunich> ok
[20:07:10] <jmkasunich> on one end you have the terminals, right?
[20:07:17] <Jymm> I was thinking of some way to take advantage of the clip as part of the holding
[20:07:21] <jmkasunich> so that end ain't gonna pop out
[20:07:24] <Jymm> correct
[20:07:57] <jmkasunich> do you have _any_ depth at all?
[20:08:06] <jmkasunich> 0.001", 0.005", 0.010"?
[20:08:24] <jmkasunich> likewise on the sides?
[20:08:43] <Jymm> If I go more than .065" in deoth, I'll break thru the wall.
[20:08:57] <jmkasunich> what about on the sides
[20:09:23] <dmessier> a little can of exaning foam... some fiberglass cloth... and a little epoxy resin is all it takes to make a cover
[20:09:48] <Jymm> dmessier SOB!!!!
[20:10:23] <Jymm> line the longest edges with weather stripping, and just compression fit it in there
[20:10:57] <dmessier> vacuum bagging is cool too... but it must be right
[20:11:19] <Jymm> jmkasunich .125" on the width and I'll break thru the walls
[20:11:34] <jmkasunich> what material are these walls?
[20:11:47] <Jymm> jmkasunich wood
[20:12:02] <jmkasunich> eww
[20:12:06] <Jymm> yeah,
[20:12:39] <dmessier> you got OOOdles a room.. .125??? LOL
[20:12:58] <Jymm> lol
[20:13:35] <dmessier> i thought you were dealing with mi usual .03 wall thikness
[20:13:53] <Jymm> dmessier in wood =)
[20:13:54] <jmkasunich> 0.030 in wood?
[20:14:15] <dmessier> after epoxy.... yes...
[20:14:21] <jmkasunich> Jymm: I'm having a real problem visualizing this
[20:14:39] <jmkasunich> there is wood under the battery, right? (assume battery laying down flat)
[20:15:07] <Jymm> jmkasunich Take a 1x4" and make a 2"x1" pocket to hold the battery.
[20:15:15] <anonimasu> Jymm: you can push the battery from behind with a spring..
[20:15:19] <anonimasu> spring tab...
[20:15:24] <Jymm> noting that a 1x4 is actually .75 x 3.5"
[20:15:34] <jmkasunich> ah, got it - a pocket in a solid piece
[20:15:40] <anonimasu> /BATTERY(0)
[20:15:42] <Jymm> jmkasunich Yeah
[20:15:45] <anonimasu> 0 is the connector...
[20:16:05] <jmkasunich> you said you have a lot of length
[20:16:08] <anonimasu> I'm sure you've seen it before
[20:16:10] <Jymm> anonimasu any suggestions on the spring and how to keep the connector end from falling out?
[20:16:18] <jmkasunich> how much? can you install the battery from the end?
[20:16:19] <anonimasu> connector end?
[20:16:21] <anonimasu> glue?
[20:16:29] <anonimasu> the spring pushes the battery aginst the connector
[20:17:03] <Jymm> jmkasunich I have about 2" on each end on the battery
[20:17:18] <jmkasunich> you can get model airplain plywood in 1/32 and even 1/64 thick
[20:17:44] <jmkasunich> pocket the hole for the battery, then pocket out 1/4" all around and 1/32 deep, glue in a cover of 1/32 plywood
[20:17:49] <jmkasunich> stuff the battery in the end
[20:18:40] <Jymm> jmkasunich so sitting on the table, would you be able to see the battery hole?
[20:18:51] <jmkasunich> I have no idea how it sits on the table
[20:19:03] <jmkasunich> you have any pics or drawings? words aren't enough
[20:19:19] <anonimasu> bbl..
[20:19:42] <Jymm> think of a tbale lamp, where the bottom of the lamp is where the battery goes, hidden underneith
[20:20:06] <jmkasunich> ok, when the lamp is sitting on the table, is the battery flat or vertical?
[20:20:12] <Jymm> flat
[20:20:23] <jmkasunich> so its a big but thin base
[20:20:29] <Jymm> yes
[20:20:46] <jmkasunich> but only 1/8" wider than the battery
[20:21:02] <Jymm> yes
[20:21:13] <Jymm> but 4" longer than the battery
[20:21:44] <jmkasunich> and you want the top surface to appear as untouched wood
[20:21:52] <Jymm> yes
[20:21:55] <jmkasunich> but the bottom can be open, or ugly, or whatever
[20:22:01] <jmkasunich> as long as it doesn't fall out
[20:22:02] <Jymm> yes
[20:22:23] <jmkasunich> what kind of wood? fine grained and strong, or coarse and crappy?
[20:23:25] <Jymm> could be all the above, but if I have to limit what can be used, so be it.
[20:23:38] <jmkasunich> how about this: use a cutter that can undercut just a tiny bit (think a 3/8" diameter sphere on a 1/4" shank)
[20:23:51] <jmkasunich> mill a pocket that is twice as long as the battery
[20:24:14] <jmkasunich> the end near the connector is undercut, so it extends just a tiny bit over the rounded corners of the battery
[20:24:26] <jmkasunich> the far end isn't undercut, it has straight walls
[20:24:27] <Jymm> ok, like a weird keyhole slot on half
[20:24:39] <jmkasunich> drop the battery in the straight side, then slide it toward the connector
[20:24:40] <Jymm> drop in the battery, slide it over
[20:24:54] <jmkasunich> still gotta figure out how to hold it once its in there
[20:25:20] <Jymm> I could get some battery clips that mount to the wall of the wood
[20:25:50] <Jymm> it'll make it a reall bitch to wire, but might be doable
[20:26:22] <jmkasunich> why can't you make the wood a little thicker or wider?
[20:27:08] <jmkasunich> btw, how thick is a 9V battery?
[20:27:47] <Jymm> 1" is common, cost goes up dramatically past that. .680"
[20:28:14] <jmkasunich> 1" nominal, 0.75 actual, I assume?
[20:28:19] <Jymm> yeah
[20:28:36] <jmkasunich> how wide is the battery?
[20:28:45] <Jymm> and any sanding drps that .75" down too.
[20:28:54] <Jymm> 1" x 2"
[20:29:18] <Jymm> 1" x 2" x .680"
[20:29:25] <jmkasunich> how wide is the board?
[20:29:40] <Jymm> 6"
[20:29:57] <jmkasunich> how long?
[20:30:17] <Jymm> 1.250"
[20:30:39] <roel01> hi all!
[20:30:42] <jmkasunich> so basically, you want to stick 1" x 2" x 0.680" inside 1.25" x 6" x 0.75"
[20:31:07] <Jymm> * Jymm nods
[20:31:10] <jmkasunich> which way is the grain running? you said 6" wide and 1.25 long, is that true?
[20:31:20] <jmkasunich> grain runs the short way?
[20:31:28] <Jymm> long way
[20:31:37] <jmkasunich> ok, so 6" long and 1.25" wide
[20:31:55] <Jymm> It's being cut out of 1x4's
[20:32:10] <jmkasunich> 1x4 is 3.5 wide, not 1.25
[20:32:24] <jmkasunich> or are you trying to get two side by side?
[20:32:58] <Jymm> No, that's the MAX that that battery can have, past that is other stuff
[20:33:11] <jmkasunich> oh, ok
[20:33:25] <Jymm> going beyond 1.25" and you break thru walls
[20:33:40] <jmkasunich> either to the outside of the item, or into another "compartment", right?
[20:33:40] <Jymm> well, hitting 1.25" and there is no wall =)
[20:33:49] <Jymm> yeah
[20:34:12] <jmkasunich> I assume that the thing powered by the battery is in the other compartment?
[20:35:07] <Jymm> yes, and I have to drill a 1.25"+ hole to get from that compartment into the battery compartment to run the wires.
[20:35:29] <jmkasunich> hmm, I was starting to get a mental image, and now its gone
[20:35:33] <jmkasunich> 1.25 hole?
[20:35:49] <Jymm> 1/8" diameter, 1.25"+ long
[20:35:54] <jmkasunich> oh
[20:36:03] <jmkasunich> duh, I was assuming 1.25 dia
[20:36:13] <Jymm> tis ok, it's the weekend =)
[20:36:22] <Jymm> brb,, need ice tea refill
[20:36:25] <jmkasunich> if the wall is so thin, why is the hole so deep?
[20:36:44] <Jymm> Just incase I need to use a walwort
[20:37:22] <jmkasunich> this is really tough
[20:37:35] <jmkasunich> because you obviously have a mental image of what we are talking about
[20:37:41] <jmkasunich> and I/we don't
[20:42:36] <Jymm> Let me see if I can draw this up...
[20:44:02] <Jymm> I gotta figure out how to draw the "lips" =)
[20:58:06] <robin_sz> meep?
[20:58:52] <giacus> here's the 'experiment' http://www.giacus.org/en/videoclips.html
[20:59:13] <giacus> text scrolling on video might be changed
[20:59:40] <robin_sz> * robin_sz wonders what a "walwort" is?
[20:59:45] <giacus> codec should be fine, for latest mediaplayer vers. too
[20:59:48] <jmkasunich> wall wart
[20:59:55] <robin_sz> yeah, figures
[21:00:17] <giacus> and file size small enough
[21:00:20] <robin_sz> how are you jmk?
[21:00:47] <giacus> ?
[21:00:50] <jmkasunich> not bad
[21:00:56] <jmkasunich> busy
[21:01:25] <giacus> robin_sz: did you shou a video of you machinaries running ?
[21:01:35] <giacus> shot*
[21:01:45] <robin_sz> nope
[21:01:55] <giacus> why not ?
[21:02:02] <giacus> would be nice
[21:03:06] <robin_sz> jmkasunich, we got busy again ... were quiet last week, but run off our feet this week
[21:03:18] <robin_sz> coolant/swarf systems for Mazak
[21:04:12] <jmkasunich> I'm making gears
[21:04:36] <jmkasunich> actually, I'm procrastinating, but I'm supposed to be making gears
[21:04:55] <robin_sz> heh
[21:05:40] <robin_sz> giacus, one comment, lose the cartoons. gotta be 25% of the download.. nice as it is .. put it up seperately
[21:06:15] <jmkasunich> agreed
[21:06:27] <jmkasunich> its one thing to have a 30 second intro to a 10 minute video
[21:06:39] <robin_sz> 'zackly
[21:06:39] <giacus> robin_sz: yeah
[21:06:41] <jmkasunich> but when the video is less than a minute, a long intro is a big much
[21:06:51] <jmkasunich> s/big/bit/
[21:06:54] <robin_sz> * robin_sz is enjoying a nice pint of beer
[21:06:56] <giacus> we could also remove transitions and video delay :D
[21:07:05] <robin_sz> weird, we still do beer in pints huh?
[21:07:06] <giacus> just back to the original format :/
[21:07:25] <giacus> nah ..
[21:07:40] <giacus> you have to impress linucnc in the mind of peoples ..
[21:07:47] <giacus> that would be the target
[21:07:57] <giacus> linuxcnc-emc2
[21:08:06] <robin_sz> shrug
[21:08:11] <giacus> :)
[21:08:11] <robin_sz> less is more
[21:08:20] <giacus> yeah ..
[21:08:32] <robin_sz> depends if you are targetting engineers or housewives
[21:08:33] <giacus> have to get out of the shell a bit ..
[21:08:46] <giacus> robin_sz: users
[21:08:49] <robin_sz> engineers aitn fussed about cute cartooons.
[21:08:52] <giacus> users are the power
[21:09:02] <giacus> you can develop how much you want
[21:09:09] <giacus> your power are users
[21:09:30] <giacus> doesnt matter is engineers, hobbist or other
[21:09:36] <robin_sz> shrug
[21:10:02] <robin_sz> well, unlike a cash-based business, the developers can ignore the users if they want,
[21:10:16] <giacus> open source projects are so
[21:11:22] <giacus> eh ?
[21:11:31] <giacus> how can ignore they ?
[21:12:12] <robin_sz> well, imagine there are two tasks to be done in the code
[21:12:29] <robin_sz> one the users are really wanting, but is dul, tedious and boring to code
[21:12:47] <robin_sz> the other is just an idea that the developers have had, but is sexy and exciting to code ...
[21:12:54] <robin_sz> which one will get done?
[21:13:12] <giacus> no .. its a different approach
[21:13:24] <giacus> may you're missing what I meant
[21:14:33] <robin_sz> must be ...
[21:14:39] <giacus> you need user for testing, debug
[21:14:46] <robin_sz> not really
[21:14:57] <robin_sz> users cant submit bug reports usually
[21:14:59] <NickServ> This nickname is owned by someone else
[21:14:59] <NickServ> If this is your nickname, type /msg NickServ IDENTIFY <password>
[21:15:00] <giacus> especially for debug
[21:15:17] <robin_sz> shrug .. they are of some use
[21:15:28] <giacus> you should say a developer do things in a certain way
[21:15:45] <giacus> he could try 1000 times and get no issues
[21:15:57] <giacus> a 'stupid' user can help , instead
[21:16:13] <giacus> just because he think different
[21:16:18] <giacus> and act different ,,
[21:16:24] <robin_sz> possibly
[21:16:27] <giacus> sure
[21:16:34] <robin_sz> but they dont contribute much to an open source project
[21:16:51] <giacus> in this sense they can
[21:16:53] <robin_sz> open source projects tend to go where the delopers want them to go
[21:17:05] <robin_sz> commercial projects go where users want them to go
[21:17:05] <giacus> but I think a big projecy needs donation
[21:17:14] <giacus> donations in money or HW
[21:17:15] <robin_sz> thats the difference
[21:17:43] <giacus> i.e I'm a free software supporter
[21:17:57] <robin_sz> sometimes OS projects do things no commercial project would do, because users dont want (or think they want) that function
[21:17:59] <giacus> I donate 250 euro/year just for that
[21:18:08] <giacus> also 100 euro on wikipedia too
[21:18:21] <giacus> this really help
[21:18:32] <giacus> but you need to become popoular before..
[21:18:33] <robin_sz> wikipaedia?
[21:18:38] <robin_sz> coo.
[21:18:53] <robin_sz> anyway
[21:18:57] <giacus> I do not pay for licenses
[21:19:11] <robin_sz> in OS projects, I dont think users are the power, its developers
[21:19:12] <giacus> as many peoples instead have to do
[21:19:33] <robin_sz> and in commercial projects, its the sales team
[21:20:20] <giacus> you should ask that to who develop night and day ..
[21:20:51] <robin_sz> shrug
[21:21:03] <robin_sz> OS developers develop what they feel motivated to do
[21:21:05] <giacus> :)
[21:21:20] <robin_sz> paid dvelopers do what they are told/paid for, no matter how dull
[21:21:52] <giacus> I didnt say to pay developer, but help
[21:22:25] <giacus> they
[21:22:27] <robin_sz> right .. and moving swiftly on ...
[21:22:35] <giacus> and there are many ways to do it
[21:22:37] <robin_sz> this is a NICE curry ...
[21:23:30] <robin_sz> mushroom biryani. mm nice
[21:23:52] <giacus> btw, I think its quite simple today find a software to run a cnc under doze
[21:24:09] <giacus> I don't know much, because I just used emc since I started
[21:24:19] <robin_sz> yeah, there is stuff around
[21:24:37] <robin_sz> not much as flexible or reliabe as EMC though
[21:24:42] <giacus> But I see lots of peoples in cnc forum they do not talk about linux or free software
[21:25:00] <giacus> just using what they have on theyr hands ..
[21:25:03] <robin_sz> but the front ends are nicer, and easier to install / set up if you are a doze person
[21:25:03] <giacus> good or bad
[21:26:07] <giacus> robin_sz: I know the difference between 'easier to use' and 'good to use'
[21:26:29] <giacus> learning curve is very different
[21:26:33] <robin_sz> tried mach2/3 yet?
[21:26:39] <giacus> but many peoples don't think that
[21:26:48] <giacus> what's that ?
[21:27:00] <robin_sz> nevermind
[21:28:34] <robin_sz> a good rule when developing code, or anyting really, machines, whatever, is to research what the market leaders are doing, get what ideas you can amd select the best features of them
[21:28:56] <robin_sz> its what artists and musicians have doen for centuries
[21:29:03] <robin_sz> enginners too
[21:29:26] <giacus> exactly
[21:29:49] <giacus> have to look at 360°
[21:29:56] <giacus> around you
[21:30:03] <robin_sz> quite ...
[21:30:40] <robin_sz> so, tomorow, when I ask "have you tried mach2/3 yet" maybe the answer will be different
[21:31:26] <giacus> I hope so for you :)
[21:31:55] <robin_sz> oh I tried it many times ...
[21:32:11] <robin_sz> its not that great to use seriously
[21:33:58] <robin_sz> but, as you say, you need to look around 360 degrees
[21:37:46] <A-L-P-H-A> dmessier, I think I'm gonna try out Astoria tonight.
[21:43:28] <Jymm> Jymm is now known as Jymmm
[21:47:59] <robin_sz> anyway .. as I was saying, that was a NICE curry :)
[21:48:09] <robin_sz> and the beer is helping wash it down
[21:53:53] <giacus> the problem is the time..
[21:54:01] <giacus> darn time, stop it
[21:59:59] <A-L-P-H-A> Whenever I think of curry, a secondary thought soon follows - many white people can't handle spice...
[22:00:05] <A-L-P-H-A> primary thought of, YUMMY.
[22:02:09] <robin_sz> strangely, of all the restaurants in the UK, curry restaurants are proably the most numerous
[22:02:41] <A-L-P-H-A> robin_sz... yeah... soo many of my friends are now thinking indian food is good... though their stomachs can't handle the spice, and their systems do a little purging.
[22:04:11] <Lerneaen_Hydra> logger_aj: bookmark
[22:04:11] <Lerneaen_Hydra> See
[22:04:39] <giacus> I love this http://en.wikipedia.org/wiki/Spaghetti
[22:05:09] <giacus> cant stay without, any 2-3 days I have to eat it
[22:06:10] <A-L-P-H-A> <shrug> spaghetti is yummy... but I like vermicilli better.
[22:06:21] <A-L-P-H-A> or however you spell it.
[22:06:24] <giacus> smallest
[22:07:36] <giacus> we do homemade tomato sauce every year in august
[22:07:59] <giacus> with tomatoes from my garden hehe
[22:08:06] <giacus> that's the big secret
[22:09:46] <giacus> for a good quality pasta you should try barilla brand
[22:09:54] <giacus> the best !
[22:10:11] <giacus> we pay it 1/3 more of other here ..
[22:10:43] <giacus> exported should be not cheap too
[22:10:51] <giacus> but its damned good
[22:13:10] <giacus> http://www.annamariavolpi.com/how_to_cook_pasta.html
[22:14:57] <giacus> and finally http://www.annamariavolpi.com/how_to_eat_spaghetti.html
[22:15:07] <giacus> doh, the video too :D
[22:18:01] <robin_sz> spaghetti is one of the few good things to come from Italy :)
[22:18:31] <giacus> few ? :)
[22:18:40] <robin_sz> Ducati and Limon Cello being the other two
[22:18:58] <giacus> in the past they were many !
[22:19:11] <giacus> indeed, all change ..
[22:19:13] <Lerneaen_Hydra> oh? is barilla good?
[22:19:24] <giacus> Lerneaen_Hydra: absolutely the best
[22:19:37] <giacus> I sayd isnt cheap too ..
[22:19:45] <giacus> compared to others
[22:19:55] <Lerneaen_Hydra> I think they are quite easy to find in sweden
[22:20:07] <giacus> probably
[22:20:17] <giacus> it comes from Parma
[22:20:22] <robin_sz> I suppose Sweden must import all its spaghetti,
[22:20:29] <giacus> same place of Prosciutto do parma (bacon)
[22:20:35] <robin_sz> too cold to grow it I assume?
[22:20:43] <giacus> or cheese (parmigiano reggiano)
[22:20:57] <Lerneaen_Hydra> hmm, I'm not sure. it depends on how sensitive it is
[22:21:18] <robin_sz> I think it needs good sun to ripen on the trees
[22:21:34] <giacus> Lerneaen_Hydra: http://it.primopiatto.barilla.com/home/htm/home.htm
[22:21:53] <Lerneaen_Hydra> here where I live it's not all too cold, we've got most standard fruit trees (plum, pear, apple and so on) and most plants that live in germany & france, so it's not all too cold
[22:22:02] <Lerneaen_Hydra> probably around 20-25°C during the summer
[22:22:39] <robin_sz> right
[22:22:58] <giacus> altitude ?
[22:23:10] <robin_sz> there was a very famous programme on the BBC in 1960, about the Swiss spaghetti harvest
[22:23:26] <Lerneaen_Hydra> where I live near 0
[22:23:35] <Lerneaen_Hydra> maybe 20-30 meters above, at most
[22:23:57] <robin_sz> xotic delicacy
[22:23:57] <robin_sz> Spaghetti is not a widely-eaten food in the UK and is considered by many as an exotic delicacy.
[22:23:57] <robin_sz> Mr Dimbleby explained how each year the end of March is a very anxious time for Spaghetti harvesters all over Europe as severe frost can impair the flavour of the spaghetti.
[22:23:57] <robin_sz> He also explained how each strand of spaghetti always grows to the same length thanks to years of hard work by generations of growers.
[22:24:38] <robin_sz> http://news.bbc.co.uk/olmedia/70000/video/_70980_aprilfool_vi.ram
[22:24:52] <Lerneaen_Hydra> what?
[22:25:04] <Lerneaen_Hydra> sounds
[22:25:11] <Lerneaen_Hydra> oh, april fools, right
[22:25:16] <robin_sz> video
[22:25:30] <robin_sz> it was the first april fool ever to be done on television
[22:25:41] <robin_sz> until then the BBC was always VERY serious
[22:25:56] <robin_sz> wait, 1957 ...
[22:26:00] <robin_sz> long time ago
[22:26:49] <giacus> robin_sz: I bought one of these for my mother http://www.vicentia.net/eng/products.htm
[22:26:58] <giacus> as gift, years ago
[22:27:13] <giacus> have to add some stepper :D
[22:28:09] <giacus> wanna try to build one like that ?
[22:28:52] <robin_sz> nah, I kn ow it grows on trees ;)
[22:29:08] <giacus> Produce over the 600 different shapes of pasta.
[22:29:14] <robin_sz> where is that pesky les_w?
[22:30:47] <robin_sz> so .. this week, ther was a company that closed locally, but hey still had one very good product, and they still have orders
[22:31:34] <robin_sz> but now, they have no factory ... so the old boss came to see me, maybe I can make them and ship them, he can still make some money
[22:33:14] <Lerneaen_Hydra> did they close les_w's factory?
[22:33:21] <robin_sz> nah, not in the USA
[22:33:24] <giacus> watching the video .. http://www.vicentia.net/filmato.wmv
[22:33:27] <robin_sz> here in the UK
[22:34:46] <Lerneaen_Hydra> oh
[22:40:49] <robin_sz> if we get the contract it will be very good
[22:41:04] <robin_sz> its like twice our current turnover :)
[22:43:17] <Lerneaen_Hydra> not bad ;)
[22:43:29] <robin_sz> all in "chromweld" too,
[22:43:48] <robin_sz> not quite stainless steel
[22:44:48] <robin_sz> 1.4003is the euro spec, or 3CR12
[22:45:08] <Lerneaen_Hydra> oh
[22:45:14] <Lerneaen_Hydra> sounds like a PITA to machine
[22:51:26] <robin_sz> its ok to laser and weld
[22:52:15] <Lerneaen_Hydra> oh, but cutting machine and so on (mill/lathe) is not?
[22:52:25] <Lerneaen_Hydra> or well, like stainless
[22:53:32] <Lerneaen_Hydra> aaaaanyway, it's late here now
[22:53:39] <Lerneaen_Hydra> cya all. (g'night)
[22:55:36] <robin_sz> night
[23:19:41] <Dallur> Is there any instance where the GUI (TkEMC) would display different Z axis position than the stepgen.x.position-fb would display ?
[23:19:54] <Dallur> I am seeing the wierdest thing, when I run in manual mode I can move Z axis and I get the same readout from TkEMC as I get from halcmd but when I start a gcode TkEMC displays something way different
[23:20:20] <Dallur> I change back into manual after running in auto and the same thing as auto ...
[23:21:37] <cradek> you probably have offsets active
[23:22:00] <cradek> in MDI mode program G90x0y0z0 and G10L2P1x0y0z0
[23:22:08] <cradek> err G92x0y0z0
[23:22:13] <Dallur> ahh
[23:23:22] <cradek> and maybe a G54 for good measure
[23:23:54] <Dallur> I implemented the feed-hold a while back
[23:24:15] <Dallur> that might be the cause
[23:24:32] <Dallur> RS274NGC_STARTUP_CODE = G50
[23:24:46] <cradek> that won't make offsets
[23:24:59] <cradek> but does it successfully turn on adaptive feed by default? I never tested that
[23:25:06] <Dallur> yup it does :D
[23:25:08] <cradek> yay
[23:25:17] <Dallur> I use it for my feed-hold function
[23:25:36] <cradek> great
[23:26:50] <Dallur> I have not implemented any offsets to the best of my knowledge, can they be included in the gcode or ?
[23:27:04] <cradek> yes gcode can set them
[23:27:28] <cradek> if you program MDI g28 does it show 0,0,0?
[23:28:04] <Dallur> I am checking
[23:29:25] <Dallur> switch to MDI, type in g28 I get work offsets 0 0 0
[23:30:24] <cradek> ok then you don't have active offsets
[23:30:35] <Dallur> and in the auto mode there are no offfsets
[23:31:08] <Dallur> The actual distance traveled should be 300 but is 11.8111 which gives a ratio of 25,4
[23:31:14] <Dallur> I know that number .... :D
[23:31:28] <cradek> ok back up, what's the problem again?
[23:31:47] <Dallur> If the gcode is in inches do the "DROs" also display inches ?
[23:32:16] <cradek> is the machine configure inches or mm?
[23:32:19] <Dallur> mm
[23:32:28] <cradek> so the gcode program has a g20 in it?
[23:32:31] <Dallur> yup
[23:32:45] <cradek> it'll probably show you mm still, but I'm not sure in tkemc
[23:33:07] <cradek> is there a problem with the distance it moves, or just the display?
[23:33:12] <Dallur> just the display
[23:33:32] <cradek> isn't there a button to change the display?
[23:33:43] <Dallur> nope
[23:33:56] <Dallur> sorry figured out what I was doing wrong I think
[23:34:01] <Dallur> (now I feel really stupid)
[23:34:20] <Dallur> There is a menu to select mm/inches and it seems after loading a file with g20 you have to change back to mm
[23:34:49] <cradek> the g20 will continue to be in effect until you change it
[23:35:03] <cradek> you can go back to mm with g21
[23:35:17] <cradek> *every* gcode program should have g20 or g21 at the beginning
[23:35:49] <Dallur> I will file this one as pebkac (problem exists between keyboard and chair)
[23:36:02] <cradek> haha ok
[23:46:22] <anonimasu> :)
