[00:27:18] <witnit_> andypugh, I got it, I was afraid to use the BFH on it but, it was just surface rust on the outer spindle(pulley vibration damper) and it had it froze tight, I put an aluminum hub over it smacked it rather hard and the whole thing dropped though the front
[00:27:33] <witnit_> through*
[00:28:50] <witnit_> I try to use BFH as last resort, luckily it will go back together nicely when i clean all this rust.
[00:29:40] <witnit_> my intentions are to remove the vbelt pully and add a toothed belt system and servo, any suggestions while i have this apart?

[00:30:38] <andypugh> TBH id you can mount an encoder on the spindle then a V-belt will be just as effective as a toothed belt with whatever motor you choose.

[00:31:36] <MacGalempsy> evening all
[00:31:45] <witnit_> I thought of this, but it seems attaching encoder will be hard as well, I want to do have a high accuracy on it, but not high cost
[00:33:57] <witnit_> I dont know how to translate the spindle revolutions into an encoder unless I add tooth pulley to it somehow, or a large bore rotary.
[00:35:21] <MacGalempsy> question, I see on the newest version of linux cnc, there is a selection for dual mesa 7i77. what would I need to do to the HAL file to make it a 7i77 and 7i84?

[00:52:25] <furrywolf> witnit: I'm planning on a large encoder disc, like
http://members.shaw.ca/SWSTUFF/spindle-encoder.html
[00:52:42] <witnit_> tyty
[00:54:17] <furrywolf> the g-code file from that site is quite nice, and will generate discs of any size
[00:54:25] <XXCoder1> furrywolf: thankfully found onme
[00:54:40] <XXCoder1> looked all over the damn bottom. didnt find it
[00:55:26] <furrywolf> http://members.shaw.ca/SWSTUFF/spindle-encoder.ngc edit variables for any size disc with any number of slots
[00:55:49] <XXCoder1> one inch, billion slots
[00:56:05] <furrywolf> sure, as long as you have a small enough endmill. :P

[00:56:23] <witnit_> maybe that will help
[00:56:28] <XXCoder1> nah its finer than size of atoms lol
[00:56:33] <XXCoder1> impossible
[00:57:05] <XXCoder1> your pdf download is amazing but need context unfortnately
[00:57:14] <XXCoder1> I do suspect its closer than I thought though
[00:57:33] <furrywolf> actually, no, the g-code is smarter than you.
[00:57:33] <furrywolf> (DEBUG, Unable to cut encoder because #<_endmill_dia> cutter is too large for a #<_encoder_cycles> cycle #<_main_track_dia> dia disk)
[00:57:33] <furrywolf> m2
[00:57:43] <XXCoder1> nice
[00:58:04] <XXCoder1> try ricious size like .0001 mm
[00:58:09] <XXCoder1> em
[00:58:20] <furrywolf> also, if you think there's fewer than a billion atoms in an inch, you failed physics and chemistry. :)
[00:58:34] <XXCoder1> actually youre right lol
[00:58:49] <XXCoder1> theres very large number of atoms across thickness of paper
[00:58:55] amnesic_away is now known as amnesic
[00:58:55] <XXCoder1> let alone inch
[00:59:31] <furrywolf> as I said, it's a rather nice file.
[00:59:59] <furrywolf> nothing in it is incredibly complicated, it's just complete and easy to use.
[01:00:12] <XXCoder1> apparently (cant trust yahoo answers) paper thickness has 1 million atoms
[01:00:30] <XXCoder1> yeah best programs or scripts or whatever is simple to use, complex result
[01:00:40] <XXCoder1> bad programs has complex process to make something simple]
[01:01:51] <XXCoder1> http://www.physlink.com/Education/AskExperts/ae49.cfm
[01:01:58] <XXCoder1> probably more crediable answer
[01:02:23] <andypugh> 25nm for an atom? Sounds big.
[01:02:29] <witnit_> buffing compound is doing wonders to this spindle, this stuff must be 35 years old ahhahaah
[01:02:32] <XXCoder1> nm is tiny
[01:02:32] <witnit_> smells terrible
[01:03:01] <XXCoder1> unless maybe they really meant um

[01:03:22] <XXCoder1> it is
[01:03:52] <andypugh> Foil is 40um and paper is 4 thou :-)
[01:03:54] <XXCoder1> paper thickness alum would be bit stiff, probably enough to make it hard to use

[01:04:26] <XXCoder1> heh I could imange some teenager anwering "umm um"
[01:04:30] <furrywolf> hydrogen is 53pm according to whatever source google uses for its factoid blurbs.
[01:04:36] <andypugh> http://www.periodictable.com/Properties/A/AtomicRadius.v.wt.html
[01:04:47] <andypugh> 1 pm = 1e-12 m
[01:05:07] Loetmichel2 is now known as Loetmichel
[01:05:22] <andypugh> So, the milllion-atoms-to-a-sheet of paper is out by a factor ofd 1000
[01:05:24] <furrywolf> according to wikipedia, "Consequently, the smallest atom is helium with a radius of 32 pm, while one of the largest is caesium at 225 pm."
[01:05:40] <andypugh> Sorry, I missed one out.
[01:05:44] <XXCoder1> interesting that hyrogen is bigger
[01:05:48] <XXCoder1> atoms is weird
[01:05:58] <andypugh> The factor is 1,000,000

[01:07:14] <andypugh> 1 millionth of a sheet of paper is 23nm. And I want to change my mind again because i remembered my previous figure as being in um and it wasn’t :-). Back to the factor 1000.

[01:07:39] <andypugh> A sheet of paper is 1 billion atoms thick.
[01:07:43] <XXCoder1> lol yeah sometimes its hard to keep track
[01:07:50] <andypugh> I used to have to know this stuff.
[01:08:00] <XXCoder1> yeah? what job?
[01:08:21] * furrywolf guesses the job was "finishing school"
[01:08:25] <furrywolf> bbl
[01:08:30] <XXCoder1> suppose paper was made from Cesium
[01:08:37] <XXCoder1> how many atoms would it be? lol
[01:08:39] <andypugh> http://link.springer.com/article/10.1007/BF00275452
[01:09:07] <XXCoder1> scientist
[01:09:15] <furrywolf> cesium foil is very much like paper, and easy to get... :P
[01:09:57] <XXCoder1> I do want the first/second most dense material in form of half inch dia tube, inch long
[01:10:06] <XXCoder1> I have samples of few elements in that form
[01:10:07] <andypugh> Osmium
[01:10:31] <XXCoder1> bet it would cost more than gold
[01:10:45] <andypugh> A pint of mercury is astonishingly heavy, and osmium is much heavier.
[01:11:07] <XXCoder1> andypugh: other thing I always wanted was tungsein "gold" bar
[01:11:13] <XXCoder1> like one they always show in tv
[01:11:26] <XXCoder1> I want one close to gold density to show how tv stuff is impossible
[01:11:34] <XXCoder1> like stuffing 10 gold bars lol
[01:11:39] <andypugh> http://www.ebay.com/itm/Osmium-metal-solid-1g-pellet-/391039127294
[01:12:05] <XXCoder1> unfortunately not in shape I want
[01:12:37] <andypugh> I have found myself wondering what “they” could do if you left a shipping contianer full of solid osmium somewhere inconvenient.
[01:13:01] <XXCoder1> lol it would crush shipping cargo bottom probably
[01:13:39] <XXCoder1> and if in pebbles, bust out and spill
[01:13:45] <XXCoder1> killing people if they was close lol
[01:15:19] <XXCoder1> http://www.periodictable.com/Properties/A/AtomicRadius.sp.wt.html
[01:15:25] <andypugh> A 40’ container is 67m3 (I checked Wikipedia). I am going to assume that Osmium is 28 tons per cubic meter. So thats close to 2000 tons in a single brick. I don’t think that there are many 2000 ton cranes. And osmium has a high melting point, is very hard, and so would be very hard to chop up. :-)
[01:15:28] <XXCoder1> interesting pattern
[01:16:03] <XXCoder1> wtf with that dip
[01:16:17] <XXCoder1> around element 60
[01:16:31] <andypugh> <chagrin> 22.6 kg.m3, I misremembered
[01:16:54] <roycroft> that sounds like an excuse for some good explsives, andypugh
[01:18:05] <andypugh> A 1500 ton brick of something that melts at 3000C would laugh at anything short of a nuke.
[01:18:36] <XXCoder1> tungsein is fun one. it would freeze in lava
[01:18:53] <XXCoder1> because lava is so damn cold compared to molen tungsein
[01:19:47] <XXCoder1> if we ever find way to "freeze" peices of space we could finally contain melted tungsein and test its properies
[01:19:51] <andypugh> Osmium is not far behind.
[01:20:25] <andypugh> 3695 for Wg, 3306 for Os
[01:20:43] <andypugh> W, I mean. Wg is something else
[01:21:09] <andypugh> (Though I know not what)
[01:21:22] <XXCoder1> I remember usa (or russia or both?) used nukes to weld 3 feet thick metal
[01:21:26] <XXCoder1> only way to do that
[01:21:33] <witnit_> this hardinge lathe i got was a military owned lathe, it appears they actually put new bearings in it instead of just buying a whole new lathe
[01:21:35] <andypugh> (I cheated on the melting points, I used Wikipedia)
[01:21:36] <witnit_> strange
[01:21:36] <witnit_> hahaha
[01:21:47] <XXCoder1> damn
[01:21:50] <XXCoder1> thats nice
[01:22:04] <andypugh> XXCoder1: not so. You can weld 3’ metals with electron beams.

[01:22:52] <witnit_> somebody definately took it apart before, improperly it seems according to how deep these marks are from hammering on a bar, but these bearings couldnt be tighter
[01:23:21] <andypugh> witnit_: Sounds good.
[01:24:59] <andypugh> I did an electron-beam welding project once. My sample was 100mm thick slabs of stainless and carbon steel welded edge to edge with no weld-prep. But the machine used can do 1m (again, with no weld prep)
[01:25:54] <XXCoder1> thick.
[01:28:04] <andypugh> Don’t ask how I got there but:

[01:28:47] <andypugh> So, if you are poisoned by Thallium they feed you micrometer blue and it comes out the other end. That must be a sight to behold.

[01:41:00] <roycroft> i generally replace phillips head screws on machinery with button head screws or socket head cap screws
[01:41:08] <witnit_> SAMES
[01:42:05] * jdh takes another look at Z's encoder sensor bolts
[01:42:11] <roycroft> on some machinery, namely some of the chinese stuff that comes with pot metal screws, i replace them all as soon as i get the machine
[01:42:38] <roycroft> on machines that have decent screws in the first place i usually swap them as i have cause to remove them
[01:42:39] <jdh> slippery slope
[01:43:03] <roycroft> you have to think of the chinese machines as kits
[01:43:11] <roycroft> and the parts are held together for shipping with pot metal fasteners
[01:44:07] <andypugh> There is nothing inherently wrong with the Phillips head
[01:44:14] <roycroft> no, there is not
[01:44:49] <XXCoder1> andypugh: in least its not standard
[01:45:08] <XXCoder1> I can't adjust my van tps because of its damn standard screws
[01:45:12] <roycroft> which is why i don't swap them out immediately when they're well-constructed phillips head screws

[01:45:41] <zeeshan|2> i think my Y servo has a bad bearing
[01:45:50] <zeeshan|2> rattling :p
[01:45:51] <andypugh> I think the problems people have are due to the smaller sizes almost working, and that Pozi drivers almost work too.
[01:46:24] <witnit_> andypugh, except improper fit between driver and head resulting in extra rear pressure to keep the taper point from acting as a wedge and forcing the screw driver out of the hole
[01:46:30] <witnit_> no there isnt

[01:47:06] <witnit_> the problem with phillips is the angles of the head and seat, nothing else
[01:47:35] <XXCoder1> witnit_: if I recall theres 2 variants of philips? and chinese ones is halfway in between so it fits nothing perfectly
[01:47:36] <roycroft> use a properly-constructed screw and a quality, correctly-sized screwdriver and you're fine
[01:47:42] <andypugh> Pozi is more parallel, but even with the Phillips the angles are small.
[01:47:47] <zeeshan|2> robertson ftw
[01:48:04] <XXCoder1> do you guys mill philips screwdrivers? lol
[01:48:19] <roycroft> one of the biggest "problems" with phillips screws is that the average homeowner not only has just a #2 phillips screwdriver, but is also not aware that there is more than one size
[01:48:24] <andypugh> I think part of the problem is that Phillips is intended as a means to drive relatively low-tensile fasteners.
[01:48:50] <tjtr33> i thought Prinz bits were same angles as Phillips but came to complete point
[01:48:57] <andypugh> Yes
[01:49:06] <witnit_> agreed, but i dont think they should ever be used on machinery

[01:49:56] <renesis> big ones
[01:50:31] <roycroft> that said, socket head screws are significantly more expensive than similar size phillips head screws
[01:50:42] <andypugh> Actually, for button heads I might prefer a slot to the hex that fits
[01:51:25] <roycroft> for permanant installation i usually use phillips head

[01:52:11] <renesis> ya srs
[01:52:17] <witnit_> my only real complaint is having to apply backpressure to the driver 9 times out of 10 with phillips style
[01:52:45] <andypugh> Hex buttons (and hex countersunk) actually have rather a small drive radius for the diameter. I would bet on Phillips against Hex for the same screw material.
[01:53:32] <andypugh> But you don’t generally see them in the same material.

[02:30:41] <XXCoder1> lemme load inkscape
[02:31:10] <andypugh> Inside the Autodesk API I can split a spline into sub-curves, but they never have fewer than 5 knots, and that can’t be a cubic Bezier, as fas as I can tell

[03:07:32] <XXCoder1> would it float?
[03:07:41] <andypugh> I wonder about the Physics of _everything)
[03:08:00] <andypugh> Yes
[03:08:11] <XXCoder1> why dont anyone ever make one
[03:08:20] <andypugh> Why bother?
[03:08:29] <XXCoder1> it would last forever I would think
[03:08:53] <andypugh> Even quite a thick balloon full of vacuum would float.
[03:09:09] <jdh> you just need a container rigid enough to hold vacuum and be lighter than air.
[03:09:16] <witnit_> metal balloon that would float? you mean a boat?
[03:09:22] <XXCoder1> creative folding would do it I guess
[03:09:24] <witnit_> ahjahjahj
[03:09:44] <XXCoder1> folding to increase strength is quite old
[03:09:51] <XXCoder1> witnit_: I didnt say boat
[03:09:57] <XXCoder1> float in air
[03:10:05] <witnit_> ohhhh
[03:10:07] <XXCoder1> density must be lower than air
[03:10:10] <andypugh> Ah, sorry, witnit asked the right question. What do you want it to float _in_
[03:10:27] <XXCoder1> yeah guess didnt give full details
[03:10:29] <XXCoder1> srry
[03:10:49] <andypugh> Floating in water, no trouble at all.
[03:10:54] <witnit_> maybe if you fill it with a helium
[03:10:58] <andypugh> Floating in air. Harder.
[03:11:03] <XXCoder1> witnit_: helium is easy

[03:11:18] <witnit_> but a vaccuum does not mean lighter by volume does it?
[03:11:20] <XXCoder1> vacuum is harder since it would have to stay full size
[03:11:25] <witnit_> like enough
[03:11:38] <XXCoder1> it is lighter, nothing has zero densiry
[03:11:48] <andypugh> Why not equalise with Helium, which is only a bit more dense than vacuum but can have equal pressure.
[03:11:49] -!- zeeshan|2 has quit [Ping timeout: 264 seconds]
[03:11:55] <XXCoder1> pressure is huge though and would crush metal thing down

[03:12:19] <andypugh> Yeah,
[03:12:38] <andypugh> Actually Hydrogen is not that mucj less dense

[08:04:41] <Cromaglious> morning
[08:05:00] <witnit_> morning crom
[08:06:03] <Deejay> mojn
[08:06:25] <witnit_> =D
[08:06:30] <MacGalempsy> hi deejay
[08:06:42] <MacGalempsy> how is your straw packaging machine working?
[08:06:50] <Cromaglious> ugh time to buy new network cables... I guess after 15 years it's time
[08:06:59] <Deejay> hi MacGalempsy! the machine works fine! :)
[08:07:20] <MacGalempsy> excellent. you been making big bucks with it?
[08:07:32] <Deejay> uh, not yet ;)
[08:07:56] <MacGalempsy> if you build it, they (moneys) will come!
[08:08:01] <Cromaglious> straw? like in weaving straw?
[08:09:13] <SpeedEvil> Automated CNC basketweaving would be fun
[08:09:20] <Deejay> dunno what weaving straw is... straw like crop straw
[08:09:27] <Deejay> hehe
[08:09:29] <witnit_> i think they do that over at reprap no?
[08:09:55] <Cromaglious> weaving straw like in straw hats
[08:10:00] <Deejay> ah
[08:10:32] <SpeedEvil> Oh - a machine for packaging straw - a baler - not a machine for packaging instraw.
[08:10:33] <SpeedEvil> :)
[08:10:40] <SpeedEvil> Balers are fun.
[08:10:50] <Cromaglious> balers are EVIL
[08:11:05] <MacGalempsy> threshers are evil!
[08:11:23] <Cromaglious> threshers are KEWLIOS!
[08:11:28] <MacGalempsy> linuxcnc is evil! lol\
[08:11:47] <Cromaglious> what's a good Linux cad program?
[08:12:01] <SpeedEvil> Blender.
[08:12:05] * SpeedEvil lolz.
[08:12:12] <SpeedEvil> You can use blender for cad
[08:12:15] <MacGalempsy> Blender is EVIL!

[08:21:33] <MacGalempsy> I had it running on 3 axis, but was afraid to start the VFD...

[08:22:14] <MacGalempsy> I like caribbean country, like jimmy buffet!
[08:22:47] <witnit_> what all components are non functional right now?
[08:23:18] <MacGalempsy> that is the problem. I could not figure out how to get the 7i84 to function...
[08:23:36] <MacGalempsy> i feel good about the wiring, but im a programming idiot
[08:24:16] <witnit_> so you mean you have it all wired you just need a little boost on getting the card talking to it?
[08:24:37] <MacGalempsy> that and some direction as to sequencing the events...

[08:44:07] <witnit_> well they need 60,000 but they want 5,000 yesterday
[08:44:21] <MacGalempsy> wow.
[08:44:34] <witnit_> I can do the 60k but my setup time is way too long
[08:44:35] <MacGalempsy> machine or cast?
[08:44:43] <witnit_> machined
[08:45:23] <MacGalempsy> my end goal is to make vintage landcruiser parts
[08:45:46] <MacGalempsy> so once the cnc part is done, it will be on to plastic injection
[08:45:52] <witnit_> :)
[08:46:53] <archivist> wont go through my sliding head :(
[08:46:58] <witnit_> ;(
[08:47:34] <archivist> rob_h has a machine but he too is in uk like me
[08:48:01] <witnit_> bummer, however, if i get any jobs in the area i will send them to you guys first =D
[08:50:26] <witnit_> you need a job for your machine archivist?
[08:50:54] <archivist> it is not cnc'd yet
[08:51:27] <witnit_> these guys that sell knife making kits and handle bolts.....
[08:51:32] <archivist> I need funds to finish conversion before it does any work
[08:51:39] <witnit_> always looking for a thousand of something
[08:51:41] <MacGalempsy> how much per part do they pay?
[08:51:45] <witnit_> pennies
[08:52:05] <MacGalempsy> so like 60k will be like 5k?
[08:52:19] <witnit_> more in this case
[08:53:00] <witnit_> the part is complex enough most would have trouble keeping up and holding a tolerance
[08:53:16] <witnit_> luckily i would run it on a 5-6 spindle automatic
[08:53:32] <witnit_> so after wages i can still do really well on it.
[08:53:44] <witnit_> I will rough quote it for 60K and let you know how much i charge
[08:54:50] <witnit_> if you look, a very large % of the material turns into shavings. since its brass and has good return i will have to figure that into the quote.

[08:59:43] <MacGalempsy_> wow. those returns are so low per part
[09:00:07] <MacGalempsy_> the guy who told me he would buy the plastics in bulk said he would pay $15 per knob
[09:00:19] <witnit_> how many?
[09:00:59] <MacGalempsy_> there are 17 different knobs in the truck, plus whatever else I can come up with . I told him a minimum of 100 sets
[09:01:52] <witnit_> my cycle time is under 10 seconds
[09:01:53] <Cromaglious> 1429 bars for 60018 units so probably 1435 10' 13/16" C36000 bars
[09:02:52] <MacGalempsy_> as of now it is only a dream until this first machine is up and going...

[09:32:56] <witnit_> Im not that good on a mill, I just dont do it enough, I drill alot of holes and turn alot of parts. my personal specialty is automating long production runs and repairing anything with moving parts
[09:32:59] <witnit_> indiana
[09:33:31] <MacGalempsy_> that sounds good, so you are burning the midnight oil like me? Im on the graveyard shift
[09:33:54] <witnit_> its my style i guess, I just cant sleep normal hours
[09:34:02] <witnit_> usually up for two days down for 1
[09:34:16] <witnit_> as it works out
[09:36:30] <MacGalempsy_> I kind of like the graveyard shift, been on it for about 3 years now
[09:36:41] <witnit_> what do you do?
[09:36:45] <MacGalempsy_> usually less stuff to deal with, but it can get rediculous
[09:36:56] <MacGalempsy_> geologic modeling
[09:37:02] <witnit_> ooh
[09:37:05] <MacGalempsy_> realtime for oil and gas wells
[09:38:04] <witnit_> so do you look at grainy ultrasounds and convert them into pretty color graphs?
[09:38:08] <witnit_> or? am i off
[09:38:34] <MacGalempsy_> if you have google hangout, I can show you
[09:38:47] <MacGalempsy_> https://plus.google.com/hangouts/_/event/c6fq454g46bctlm5cpqu7l7t62g
[09:38:48] <witnit_> i try to not have google anything :/
[09:38:59] <witnit_> but then i search.... and they know all
[09:39:00] <MacGalempsy_> lol. this is the reprap hangout
[09:39:21] <witnit_> yeh, no google account :/
[09:39:23] <MacGalempsy_> I use gamma data, and others if they pay up . then model where we think we are in section
[09:40:03] <MacGalempsy_> in some of these wells, being in zone for 5000 ft compared to 500 ft could be millions in returns over the life of the wells
[09:41:27] <MacGalempsy_> this is like my 8th or 9th year in the industry. its kind of scary right now with prices being so low
[09:41:40] <MacGalempsy_> hence the reason for wanting to learn cnc machining
[09:42:52] <MacGalempsy_> software design is easy, just not programming
[09:42:59] <witnit_> I suggest get a quality small hand lathe or mill, buy brass, aluminum, delrin, steel, and stainless steel material and just play around
[09:43:09] <witnit_> do it for hours, just to make shavings
[09:43:33] <witnit_> you will understand so much more when you have problems later with your cnc
[09:43:43] <MacGalempsy_> ok. i have been buying scrap aluminum and carbon on ebay when the prices are fair
[09:44:33] <witnit_> is it chatter, is my tool dull, am i cutting too fast, is the machine not ridgid, once you get a feel for a machine and the materials you can diagnose a majority of problems just by listening to the machine cut
[09:45:48] <MacGalempsy_> hmmm. ok
[09:45:54] <archivist> is the tool hanging out too far from the holder
[09:46:25] <witnit_> is there enough relief in my tool to cut at this feedrate...
[09:46:37] <archivist> is the material work hardening or free cutting
[09:46:53] <witnit_> some tool steel and a bench grinder is nice too
[09:47:00] <archivist> do you have a crap finish due to built up edge
[09:47:21] <witnit_> do you have build up on ledge due to wrong coating type?
[09:47:34] <archivist> or lack of lube
[09:48:29] <archivist> there are some good youtube vids on built up edge
[09:48:46] <witnit_> MacGalempsy_,
http://lindsayengraving.com/tour/photos/hardinge1small.jpg
[09:49:01] <witnit_> these are nice and fairly common
[09:50:42] <archivist> and...cnc is not always the right answer for very low qty production
[09:50:47] <MacGalempsy_> not sure I want to get a lathe.
[09:51:07] <archivist> I cannot work without a lathe
[09:51:11] <witnit_> same
[09:51:14] <MacGalempsy_> barely have enough room in my garage for the stuff I got
[09:51:17] <witnit_> i can do without a mill
[09:51:19] <witnit_> a lathe tho
[09:51:23] <witnit_> is so much
[09:51:30] <MacGalempsy_> I guess it depends on what you want to get into

[17:26:36] <SpeedEvil> Really, really not.
[17:26:46] <SpeedEvil> That basically guarantees no adhesion
[17:27:11] <SpeedEvil> You can - with the proper wax design - get a wax output that looks like toothpaste pretty-much
[17:27:16] <SpeedEvil> not liquid

[19:06:39] <__rob> I am assuming this can't really be the backlash setting
[19:06:48] <__rob> as it would be larger/smaller inside and out
[19:06:59] <__rob> morning :)
[19:07:10] <__rob> well, evening here.
[19:07:28] <__rob> I am using inventor to generate the toolpath
[19:07:30] <Cromaglious> you running inch or metric lead screws?
[19:07:34] <__rob> metric
[19:08:05] <_methods> what do you mean you're getting smaller on inside and same on outside?
[19:08:24] <__rob> so calipers on an inside pocket, are 0.17mm too small
[19:08:34] <_methods> the pocket is undersize
[19:08:37] <__rob> calipers measuring the outside profile cut of the part is 0.17mm too big
[19:08:48] <_methods> that's your offset then
[19:08:50] <_methods> that is normal
[19:09:04] <__rob> what offset ?
[19:09:11] <Cromaglious> tool offset
[19:09:12] <_methods> you need to make a wear offset of .085mm
[19:09:18] <tjtr33> or cutter diameter is seen the same by 2 programs
[19:09:19] <_methods> yes tool offset
[19:09:32] <__rob> yea, ok, but then surely if I have measured the tool to be correct
[19:09:36] <zeeshan> linuxcnc has wear offset?
[19:09:37] <__rob> and entered this into Inventor
[19:09:42] <__rob> it should be exactly right

[19:11:47] <__rob> just nice to know though where thats from
[19:11:53] <__rob> if it is indeed the tool offset thats needed
[19:12:00] <zeeshan> ok you have 0.0066" error
[19:12:00] <__rob> or if its perfect, and the measurement on the tool is wrong
[19:12:17] <tjtr33> yeah, you can make the part, but you still have a problem and need to find the source
[19:12:18] <zeeshan> your calipers are accurate to like +/- 0.003
[19:12:19] <__rob> purely from the point of view of applying the 'fix' to other tools
[19:12:59] <__rob> I'll do as jdh suggested
[19:13:16] <__rob> if thats it, then I guess I need to run each tool on a test cut
[19:13:21] <zeeshan> if you're really trying to aim for .17mm accuracy
[19:13:23] <zeeshan> you need a micrometer
[19:13:25] <zeeshan> not a caliper
[19:13:26] <_methods> that's how everyone does it
[19:13:35] <zeeshan> even if you cutr a slot
[19:13:36] <__rob> I didn't know :)
[19:13:37] <zeeshan> and measure with a caliper
[19:13:39] <_methods> you measure the tool and get as close as possible
[19:13:40] <zeeshan> you're gonna be off
[19:13:53] <_methods> but you'll always have to make some tool offset adjustments

[19:14:51] <zeeshan> or if you got gauge blocks you can sneak up on it
[19:15:09] <zeeshan> or you can use 2 gauge blocks and a regular caliper
[19:15:11] <zeeshan> er regular mic

[20:02:31] <dirty_d> i measured it at under 0.001

[20:05:44] <furrywolf> I guess if your machine had pretty bad rigidity issues it could do that...
[20:06:01] <furrywolf> poorly tuned servos overshooting?
[20:06:05] <dirty_d> steppers
[20:06:45] <dirty_d> if the cut is too light could the small chips get stuck between the cutter and side of the hole wearing it bigger?
[20:06:47] <furrywolf> are linear cuts the correct length?
[20:06:59] <dirty_d> yea linear cuts were to within 0.001 over 2"
[20:07:21] <furrywolf> I guess there's theoretically possible, but I'd consider it unlikely.
[20:07:25] <furrywolf> that's

[20:09:55] <dirty_d> ill have to try going slower and see if it helps
[20:10:32] <furrywolf> it's take a lot of slop to overshoot four thous... and with steppers I don't think you'd have the speed to do it.
[20:10:37] <dirty_d> it would make sense that the smaller hole would be off by more than the bigger one because there would be higher angular acceleration
[20:11:02] <dirty_d> but i dunno

[20:19:31] <jdh> its a fad
[20:19:50] <dirty_d> i diversify
[20:22:09] <furrywolf> I'm surprised the planner is feeling the need to go large instead of small cutting a hole.
[20:23:23] <furrywolf> that is, when cutting a circle, why go large? are you right up against the maximum acceleration of your machine, and it's cutting large so it can keep the feedrate up?
[20:28:04] <dirty_d> well that confirms it
[20:28:25] <dirty_d> http://pastebin.com/DuCtiYdS
[20:28:42] <dirty_d> the actual path is noticable larger than the programed path if i run that

[22:47:11] <Cromaglious> I just added a root cron job to do that every day
[22:48:26] <Cromaglious> bit more detained than that.. it goes through all the user dirs and changes everything inside a users dir to their username
[22:49:25] <Cromaglious> I started doing that back in slackware pre elf kernel days
[22:50:02] <Cromaglious> damn it Samsung D3 is a 3.5" drive

[23:08:44] <MacGalempsy_> can someone take a look at this website and tell me what I am doing wrong?
http://rivendell.tryphon.org/wiki/ELO_touchscreen_setup_%28debian/KDE%29
[23:09:15] <MacGalempsy_> I get down to calibration, "Then extract Touchcal and compile" then the trouble starts

[23:27:01] <witnit> MacGalempsy, what did you type to install libcurses?
[23:27:14] <MacGalempsy> apt-get install libncurses5-dev
[23:27:19] <witnit> use sudo
[23:27:32] <MacGalempsy> root
[23:27:51] <witnit> yeah, when you install something to the system, its going to want your root
[23:28:25] <MacGalempsy> it stays it is installed
[23:28:32] <witnit> proceed
[23:28:45] <MacGalempsy> but then the line says ./configure
[23:28:57] <MacGalempsy> when I write that it says directory not found
[23:29:01] <witnit> type ls
[23:29:08] <witnit> and look at your options
[23:29:29] <witnit> are you in the right folder?
[23:31:02] <witnit> according to the guide, its asking you to download the software called Touchcal, but you will need to extract the contents of the Touchcal file
[23:31:45] <witnit> once you have it downloaded and extracted you can cd (change directory) to the folder of freshly extracted files =D
[23:32:07] <witnit> in there should be the things you need to start compiling
