[00:34:24] <skorket> someone from another channel asked about maximum rpm of a stepper motor he had. I have them too and was wondering what the answer was. The datasheet is here: http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Robotics/42BYGHM809.PDF . From this, how does one calculate maximum rpms? How is that derived based on the load?
[00:36:46] <archivist> those types od data sheets should be burnt
[00:36:51] <archivist> of
[00:37:23] <archivist> you need a torque v step rate graph
[00:38:13] <skorket> archivist, so it is not possible to calculate it from the datasheet given?
[00:38:14] <archivist> the torque drops with step rate, you have to match that with your load
[00:39:14] <archivist> you would have to test on your machine, but even then you need to run a bit slower to give yourself some headroom
[00:39:24] <skorket> and it's presumably non-linear and not easy to impossible to derive from that datahseet?
[00:39:49] <archivist> impossible from that datasheet
[00:40:21] <skorket> too bad.
[00:40:26] <archivist> wild guess by knowing other stepper motor curves
[00:41:22] <archivist> but load effects your real maximum too, if you want high speed go with servo motors
[00:43:48] <archivist> skorket, http://www.velmex.com/motor_torque.html
[00:44:48] <archivist> shows variation with stepper size
[00:46:18] <skorket> archivist, thanks, that's what I was looking for. Obviously different for each motor and you really need the datasheet, but at least that gives a ballpark
[00:47:56] <archivist> thats what I mean by wild guess by looking at another maker
[00:49:28] <archivist> and also shows what a reputable supplier will tell you about their motors
[00:49:30] <skorket> It looks like it's pretty much linear for the latter region
[00:50:10] <archivist> rapidly dropping to 0, this is why the load matters for speed matching
[00:50:12] <skorket> are they selling?
[00:53:18] <archivist> they have a stepper motor price list
[00:54:17] <archivist> you probably will fall of chair at the prices
[00:54:23] <archivist> off
[00:56:13] <skorket> yeah, just talked to some chinese manufacturer, it's like $15, shipping included, for the one with the datasheet I just gave
[00:58:41] <archivist> the cheap manufactures are just making stuff, it turns therefore its ok, better makers test to a specification
[02:18:48] <DJ9DJ> moin
[03:36:13] <Loetmichel> mornin'
[07:35:16] <jthornton> doesn't look like a good day for mountain bike riding...
[07:35:34] <Tom_itx> rain?
[07:35:39] <Jymmm> time for the goldwing
[07:36:09] <jthornton> been raining off and on all night and not a peep of sun this morning
[07:36:23] <Jymmm> time for the goldwing and raingear
[07:36:46] * archivist blames jthornton for the rain over here
[07:37:30] <Tom_itx> fwd the rain msg to me
[07:37:31] <jthornton> I don't even have any frog toggs
[07:37:34] <Tom_itx> we need it
[07:38:11] <Jymmm> I met a 74yo lady that rode cross country on a regular basis, even in the rain.
[07:38:31] <Tom_itx> mountain bike?
[07:38:38] <Jymmm> 750cc
[07:39:29] <jthornton> Trek
[07:39:41] <Jymmm> They would never let her ride alone, but she did ride. Very cool lady, met their group at a MC overnighter
[07:46:51] <Jymmm> Heh, they had a wet tshirt contest that was getting "colorful". The sheriffs were parked up on a hill overlooking the crowd/stage area. Well as the festivities were getting more exciting, so was the crowd. Then all the lights/music died. Everyone thought the sherriffs had pulled the plug to clam the crowd down so they started booing the sherriffs. The sherriffs turn on their spotlights aimed at the stage area. They had just tripped a break
[07:46:51] <Jymmm> er is all =)
[07:47:07] <Jymmm> calm
[07:50:00] <Jymmm> That's all they needed is a bunch of angry drunk bikers that probably have more firepower then they could imagine pissed off at them =)
[07:51:37] <Jymmm> This was up in the National Forest, so any backup was at least 30 minutes away at minimum =)
[08:55:15] <IchGuckLive> hi all
[08:55:26] <IchGuckLive> african heat wave hit germany
[08:58:04] <Jymmm> ... news at 10pm!
[09:00:11] <jthornton> how do you copy a file from somewhere to the current directory? cp -r path/to/directory
[09:00:28] <jthornton> then what would say here for destination directory?
[09:00:46] <jthornton> I guess I could pwd
[09:00:58] <Jymmm> ./
[09:01:00] <IchGuckLive> why not via nautilus ?
[09:01:03] <jdh> .
[09:01:32] <jthornton> . seemed to work thanks
[09:01:40] <jthornton> what is nautilus?
[09:01:43] <jdh> nautilus is non-unixy, cp is very unixy.
[09:02:07] <Jymmm> jthornton: You can also represent the name of the current directory by using the notation dot (.). The dot (.) notation is commonly used when running programs that read the current directory name.
[09:02:23] <jthornton> cp -r /usr/share/doc/linuxcnc/examples/sample-configs/gladevcp .
[09:03:39] <Jymmm> jdh: If ../ is up one level, what is ./ ?
[09:03:51] <Jymmm> and dont say a website
[09:03:59] <jdh> that's /.
[09:04:03] <Jymmm> =)
[09:04:45] <jdh> it is the current dir also, but might confuse some things
[09:05:14] <Jymmm> ok
[09:05:54] <IchGuckLive> is linuxcnc now running on a 64bit system 10.04 ?
[09:06:01] <IchGuckLive> 12.04
[09:06:12] <IchGuckLive> B) O.O
[09:06:33] <IchGuckLive> 12.04 woudt be good on the new education mashines
[09:06:49] <IchGuckLive> as FEM is also there
[09:07:40] <mrsun> FEM ?
[09:08:01] <IchGuckLive> Z88 aurora a structural analysis open source
[09:08:01] <archivist> finite element modelling
[09:08:06] <IchGuckLive> Yes
[09:09:38] <IchGuckLive> Precise is this 12.04 or 11.10
[09:10:19] <timholum> I beleve I know the answer to this, but is it possible to run linuxcnc without rtia or rtlinux installed?
[09:10:20] <IchGuckLive> http://buildbot.linuxcnc.org/ here we shioudt ad the number also not only the names
[09:10:32] <IchGuckLive> no
[09:10:45] <IchGuckLive> only in simulation mode
[09:11:16] <timholum> that is what i was afraid of, :( there goes my hopes of having my beaglebone running linuxcnc :(
[09:11:43] <timholum> atleast until someone makes rtai work on the cortex-a8 processor line
[09:12:48] <IchGuckLive> i need to restart the system i updated 500MB
[09:14:54] <IchGuckLive> Back
[09:15:12] <IchGuckLive> now on kernel 42
[09:37:13] <IchGuckLive> timholum: a 3-axis router in use
[09:38:31] <IchGuckLive> oh i need to go BYe
[09:49:28] <Jymmm> Alright, could someone explain something to me please.... I'm getting quotes of having SS shim stock. One part is a 6x12" rectangle with 1/4" radius corners, and 16 1/4" holes in it for around $15/ea. The other is a 3" disc with two 1/4" holes for around $12/ea. What am I missing here? Why is the disc SO expensive compared to the rectangle with all the work on it?
[09:50:54] <cncbasher> your paying for the waste materal too
[09:51:19] <archivist> and handling and setup
[09:51:31] <Jymmm> Ok, fine, but the material cost is nothing compared to the time
[09:52:25] <cncbasher> it's more the setup and handling and labour time
[09:52:28] <Jymmm> the disc is 1/4th the size of the rectangle and 1/8th the holes.
[09:52:44] <archivist> what was the qty you asked for
[09:52:46] <Jymmm> is cutting a circle THAT much of a big deal?
[09:53:27] <archivist> do they have to buy a new punch to suit your job
[09:53:55] <Jymmm> Well, I asked for 100, 1000, and 10000 qty to be quoted. on this quote I only got a qty of 30, but it's the ratio of cost between them. No die, it's waterjet
[09:55:06] <archivist> water jet is low qty iirc wrong technology for 10k
[09:55:18] <cncbasher> it will be minimun hourly rate they need to make
[09:55:24] <Jymmm> he says they can stack them
[09:55:33] <Jymmm> on the waterjet
[09:55:46] <archivist> they can only stack so many
[09:57:33] <archivist> I imagine punching would be cheapest option
[09:57:47] <Jymmm> They can stack 30 high.
[09:59:00] <archivist> are your dimensional specifications too tight also
[10:00:33] <Jymmm> it's a 3" disc and I specified their worse tolerances are fine. I even said if they have to adjust the dimensions for least amount of waster material would be acceptable.
[10:00:42] <Jymmm> wasted
[10:01:02] <L84Supper> I've gotten crazy high pricing by waterjet at some places, like I was going to get them to their monthly quota on 2 days of work
[10:01:38] <L84Supper> it might just be that waterjet shop
[10:02:00] <Jymmm> It's not the price on the rectangle and much as the high ratio between the rctangle and the disc that puzzles me.
[10:02:37] <L84Supper> ask them
[10:02:39] <archivist> being shim does it need another waste but thick layer to support it
[10:02:39] <Jymmm> AND the rectangle includes laser engraving on it
[10:02:57] <cradek_> did you ask them? if there's something hard about the design and you're willing to adjust it, I bet they will work with you
[10:03:08] <L84Supper> see if you get a logical answer
[10:03:54] <Jymmm> cradek: It's a 3" disc with two 1/4" holes 180 degrees apart from each other, 1/2" in from edge.
[10:04:41] <syyl> will they cut the shim stock with abrasive added, or just with plain water?
[10:05:15] <Jymmm> and yes, I just did ask for higher qty and why the ratio is so high, just waiting for the reply.
[10:05:18] <Jymmm> syyl: no idea
[10:21:48] <Jymmm> what time is it in .DE ?
[10:22:08] <syyl> 17:10
[10:22:12] <Jymmm> ty
[10:24:20] <Jymmm> syyl: you in .DE ?
[10:24:27] <syyl> still, yes
[10:27:51] <Jymmm> syyl: you near Hamburg by chance?
[10:28:25] <syyl> 680km near ;)
[10:28:49] <Jymmm> syyl: that's like 10 minutes away walking, right?
[10:29:10] <syyl> 5min
[10:29:18] <syyl> after 6 hours of driving ;)
[10:29:51] <Jymmm> but but but EU public transit is fast and cheap =)
[10:30:08] <syyl> thats a myth
[10:30:15] <Jymmm> nuh uh
[10:31:18] <Jymmm> Hmmm, I came up with a modified Trilene Knot
[10:33:30] <Jymmm> At step #13, pass the tail through the 5-7 wraps, then finish the remaining steps. Then it's no long secured by a single point and the tail is now parallel to the standing end. http://www.animatedknots.com/trilene/index.php
[10:34:07] <Jymmm> s/long/longer/
[11:09:03] <skunkworks> Its a very easy solution- just switch the charge pump off by the little
[11:09:03] <skunkworks> switch on the G540. Charge pump is an old idea that offers no useful
[11:09:03] <skunkworks> protection. Just dont turn on the power to the G540 until the software-
[11:09:03] <skunkworks> mach or linuxcnc- is running and in control of the port.

[11:09:20] <skunkworks> yeck
[11:21:44] <Loetmichel> re @ home
[11:27:43] <IchGuckLive> hi all
[11:33:14] <pcw_home> skunkworks I guess safety is a old idea
[11:34:22] <Jymmm> dumb question... is a 1/4" radius one 4th of 1/2" circle - for purposes of determining circumference of the radius
[11:36:54] <archivist> so dumb I wont answer
[11:39:37] <Jymmm> or is it 1/4th of a 1/4" circle?
[11:40:17] <skunkworks> pcw_home, I guess.
[11:41:31] <skunkworks> pcw_home, did you see this? Its a very easy solution- just switch the charge pump off by the little
[11:41:31] <skunkworks> switch on the G540. Charge pump is an old idea that offers no useful
[11:41:31] <skunkworks> protection. Just dont turn on the power to the G540 until the software-
[11:41:31] <skunkworks> mach or linuxcnc- is running and in control of the port.
[11:41:31] <skunkworks> ron ginger
[11:41:36] <skunkworks> sorry
[11:41:53] <skunkworks> pcw_home, did you see this http://www.cnczone.com/forums/servo_motors_drives/159994-servo_advice_needed.html
[11:42:41] * archivist hands Jymmm PI
[11:44:02] <Jymmm> I know it's pi, but I'm asking the definition of "radius", if someoen says it has a 1" radius, is that really a 2" circle, cut into four pieces? (one per corner)
[11:44:30] <Jymmm> or is it a 1" circle cut into 4 pieces
[11:47:50] <archivist> you are confused
[11:48:43] <archivist> radius has no connection to the number of pieces a disk is cut into
[11:51:24] <archivist> schoolboy maths is at http://en.wikipedia.org/wiki/Circle
[11:52:31] <Jymmm> Ok, if a 3" square has 1/2" radius corners, how long is the straight edge of any one side?
[11:53:07] <syyl_> he is not confused
[11:53:10] <syyl_> he is confusing
[11:53:35] <cradek> since the radius is the distance from center to edge, and you'll have two radii to subtract from your square's side, you'll get 2"
[11:54:11] <archivist> he need to learn not be spoon fed :)
[11:54:37] <cradek> after that question, I see why he's asking about a cut-up circle
[11:55:33] <Jymmm> cradek: ty
[11:55:33] <cradek> if you cut up a pecan pie into any number of slices, then you measure the edge of a piece before eating it, it's always exactly a radius if you're good at cutting pies
[11:55:56] <cradek> so you've got a quarter of a pie at each corner
[12:00:52] <Jymmm> then the circumfernce of a corner would be: r2Pi/4, or r*pi*0.5 if I got the right, and not r*pi/4.
[12:01:21] <Jymmm> I do appreciate the help =)
[12:02:08] <cradek> yes circumference is 2 pi r, so 1/4 of that is 0.5 pi r, like you say
[12:02:45] <cradek> are you trying to calculate the whole circumference of your rounded rectangle part?
[12:02:50] <archivist> as it is a square with 4 rounded corners you can short cut the circumference calculation it is one circle
[12:04:20] <Jymmm> cradek: I was trying to determine the travel distance of a rectangle for 1/4" radius corners.
[12:05:05] <cradek> gotcha
[12:05:14] <Jymmm> cradek: many many surface inches of travel are needed for the tool.
[12:05:29] <Jymmm> cradek: how many surface inches of travel are needed for the tool.
[12:05:42] <archivist> depends on tool dia
[12:05:57] <Jymmm> laser beam
[12:06:20] <cradek> it's true if you do any kerf adjustment the path clearly gets longer
[12:07:27] <Jymmm> I could always increase the margin by the kerf value.
[12:07:58] <Jymmm> s/increase/expand/
[12:09:33] <cncbasher> you should not need to add any adjustment for kerf if sending to a laser cutter .. they will adjust to suit the machine being used
[12:10:45] <Jymmm> cncbasher: It's not for that, it's for calculating the surface inches traveled. to get a guesstimate on time to completion.
[12:11:19] <Jymmm> (assuming a constant speed)
[12:12:11] <cncbasher> for one single part or multiple
[12:12:33] <Jymmm> nested parts per sheet.
[12:13:23] <cncbasher> difficult as you are going to have to presume the path taken
[12:13:46] <cncbasher> i.e path between parts etc
[12:13:47] <Jymmm> I do have some somewhat control of that actually.
[12:14:39] <cncbasher> if your using cam software they usualy will give you an estimation
[12:14:46] <cncbasher> of time
[12:15:09] <Jymmm> Not on mine
[12:15:36] <cncbasher> we have ours also giving running costs , based on gas usage , consumables etc ..
[12:16:47] <Jymmm> cncbasher: My laser uses a "print driver" for the cam aspect. It's basically like a glorified plotter. so I can send pretty much any job to it from any application that can print.
[12:17:13] <cncbasher> laoslaser ?
[12:17:26] <Jymmm> ULS M-300
[12:18:11] <cncbasher> yea the epilog
[12:21:48] <cncbasher> easiest way is to take the path of one part and multiply and add a % , then multiply number of parts
[12:21:59] <cncbasher> will get you close
[12:22:20] <Jymmm> It's calculating the single part that's the complicated part.
[12:23:05] <cncbasher> if you have the part in cad format then it should be easier
[12:23:25] <cncbasher> just take the measurments and add
[12:24:00] <cncbasher> or are you engraving .. so need to know the actual tool path , which is more complicated
[12:24:33] <cncbasher> i guess engraving as your using the m-300
[12:25:27] <cncbasher> have you access to the cam source code ?
[12:28:19] <IchGuckLive> are you talking about setting a part multiple on a metell sheet for laser cut ß
[12:29:54] <IchGuckLive> the new 2Aug heekscnc has a laser post where you can set the lines and rows
[12:30:48] <cncbasher> visicut also probably would with a tweat
[12:30:52] <cncbasher> tweak
[12:31:06] <IchGuckLive> i think i will now make a video tutorial on how to modify the postprocessor for your own nedd
[12:32:13] <pcw_home> Wheres my pecan pie?
[12:32:50] <IchGuckLive> in the pven
[12:32:56] <IchGuckLive> owen
[12:33:22] <IchGuckLive> oven B)
[12:34:08] <IchGuckLive> tomorrow here is the all american walking day as there where 50k+ american stationed in the region we need alot of coke at 40Deg C
[12:35:34] <IchGuckLive> pcw_home: BBQ oven line is 150+ meters
[12:39:27] <pcw_home> Never got hot this summer, still ~55F in the mornings
[12:40:12] <IchGuckLive> here the african temp comming in this weekend til wend
[12:40:56] <pcw_home> This is just local to the SFBA 30 miles from here its normal
[12:42:30] <IchGuckLive> pcw_home: wildfire in the range
[12:42:50] <IchGuckLive> 72 burning in SF as National wether
[12:43:13] <IchGuckLive> washington is hard hit this seasson
[12:44:06] <IchGuckLive> pcw_home: are there windmills i the SFBA
[12:44:26] <pcw_home> Yes I know drought and wildfires everywhere (but somehow its been the coolest summer here I remember)
[12:44:32] <IchGuckLive> Bakersfield plenty of them sa far as you can see
[12:44:59] <pcw_home> Yes not close here but within 30 miles or so are big wind farms
[12:45:39] <IchGuckLive> 4 weeks ago we opend owr solarpark here with 15600 modules
[12:46:03] <IchGuckLive> and 60+ windmills with 1,5MW here
[12:46:17] <IchGuckLive> etch
[12:46:25] <jdh> who makes the windmills?
[12:46:35] <pcw_home> Its funny PV solar has gotten cheaper than most other ways so a lot of solar-thermal plans have been shelved
[12:46:39] <IchGuckLive> the energie producers most
[12:47:13] <IchGuckLive> 77USD in china 340WP
[12:47:52] <pcw_home> There is of course a suit charging the Chinese with dumping...
[12:48:10] <IchGuckLive> and if seen 10KW inverters at 500USD
[12:48:17] <archivist> hmm fleabay toy 130749287101
[12:49:12] <IchGuckLive> pcw_home: agree here its the same 5 big solarproducers went out this year Bunkropsy
[12:58:27] <IchGuckLive> im off i need to col my wounds as i had a bycicle accident yesterday 2 full turns on concrete AUTSCH!
[12:58:49] <IchGuckLive> i hidded the sideway
[13:02:57] <pcw_home> Ouch. I fell and broke my collar bone when I was about 40, and decided I was a getting a little too brittle for bicycles
[13:03:14] <jdh> guy at work died on his Monday.
[13:06:19] <pcw_home> One mistake and the rather grim physics of height above the street, gravity, forward velocity and a hard surface are upon you
[13:07:33] <pcw_home> or some idiot on a cell phone plows into you
[13:14:52] <jdh> or an old lady in a 1994 cadillac
[13:24:57] <Jymmm> To those of you who ride bicycles... Do you stop at stop signs/lights?
[13:25:54] <jdh> no, they don't.
[13:26:16] <syyl_ws> :D
[13:27:02] <Jymmm> jdh: Yeah, the president of a local bicycle club admited that 95% of the time him/members don't.
[13:27:44] <jdh> that is obvious to anyone who drives near bicylists.
[13:28:12] <Jymmm> Yeah, but it's nice to hear from the horses mouth, less bias.
[13:30:19] <skunkworks> or ride on sidewalks and assume pedestrian rights.
[13:31:01] <Jymmm> skunkworks: 7mph?
[13:32:46] <skunkworks> riding through intersections
[13:33:30] <Jymmm> ah
[14:34:03] <jthornton> no stop signs where I ride...
[14:35:22] <jthornton> dang, still can't see any computers on my network
[14:35:46] <Jymmm> Alright, I'm taking quotes to have a punch and die I can chuck in my drill press for create a 2.5" disc
[14:36:34] <Jymmm> bonus if it can punch two 1/4" holes in the disc too
[14:37:53] <Jymmm> jthornton: can you ping em?
[14:39:32] <jthornton> I've not tried that
[14:40:12] <jthornton> yes I can ping one

[14:43:32] <Jymmm> 138? 139?
[14:44:04] <archivist> jymm drill press may not be accurate or strong enough, accuracy can be fixed by using a bolster
[14:44:39] <Jymmm> archivist: arbor press maybe?
[14:45:42] <archivist> some of the cheap arbor presses have a lot of side play
[14:46:41] <syyl_> you can build a guided tool
[14:47:00] <syyl_> then a cheap arbor press would be good enough
[14:48:01] <archivist> see also die set
[14:48:24] <archivist> which has the guides
[14:48:43] <archivist> there is a suitable one in my truck :)
[14:48:49] <syyl_> thats the premium variant
[14:48:51] <syyl_> :)
[14:51:15] <skunkworks> I would think you could find some die sets pretty cheap
[14:51:24] <archivist> I got some tooling from a couple of places, one was an antenna maker, the other die set was from the experimental dept of Metal Box Co
[14:51:28] <skunkworks> we used a set to make a simple punch for aluminum
[14:51:48] <skunkworks> *used die sets
[14:52:19] <archivist> a few springs and you can easily make a double action set
[14:54:36] <archivist> Jymmm, should be hunting for a flypress
[14:55:34] <jthornton> Jymmm, what am I looking for with telnet?
[15:41:01] <jthornton> power cycle all fixed it Jymmm
[15:54:59] <Nick001-Shop> hi - just upgraded to 2.5.1 and now won't recognize loadrt hostmot2 command - doesn't recognize loardt by itself - what did I miss?
[15:56:00] <Nick001-Shop> loadrt
[15:56:13] <cradek> please use pastebin to show us exactly what you are doing and seeing
[15:57:34] <Nick001-Shop> nick@Hardinge1-2:~$ loadrt hostmot2
[15:57:36] <Nick001-Shop> loadrt: command not found
[15:57:37] <Nick001-Shop> -Don't have a pastebin account-(
[15:57:51] <cradek> loadrt is not a shell command. you can't type hal commands at the shell
[15:59:16] <cradek> % halrun
[15:59:16] <cradek> halcmd: loadrt and2
[15:59:16] <cradek> halcmd:
[15:59:32] <cradek> also, you don't need an account to use pastebin.com, pastebin.ca, etc
[16:00:11] <Nick001-Shop> Manual says The hostmot2 driver must be loaded first, using a HAL command - thought it was a terminal command
[16:06:11] <Nick001-Shop> think its there now - tried twice and second time says file exists.
[16:06:13] <Nick001-Shop> is the file there permanently?
[16:13:13] <skunkworks> what are you trying to do?
[16:17:38] <Nick001-Shop> trying to load mesa firmware for 5i20
[16:19:11] <skunkworks> you normally don't load it manually - it would be in your hal/ini file...
[16:20:03] <Nick001-Shop> got the first to load and now it wont take the command loadrt hm2_pci config="firmware=hm2/5i20/SVST8_4.BIT
[16:20:05] <Nick001-Shop> num_encoders=3 num_pwmgens=3 num_stepgens=1" This is whats in the integrators manual
[16:20:19] <DJ9DJ> gn8
[16:22:01] <Nick001-Shop> ok- I see it now - nice of the manual to point it out
[16:22:07] <skunkworks> Nick001-Shop, I would first try the hm2-servo sample config and modigy that...
[16:22:18] <skunkworks> *modify
[16:22:40] <skunkworks> There is a generic 5i20 config within that
[16:24:11] <Nick001-Shop> if I leave encoders and pwmgens at 3 and only use 2 - will it notice or do I have to make it 2 to get rid of Z calls
[16:25:55] <Tom_itx> archivist on those dies how much lip did they leave for sharpening?
[16:26:03] <Tom_itx> i'm curious how others do that
[16:26:16] <skunkworks> Nick001-Shop, actually - there is a config wizard for mesa... http://www.linuxcnc.org/docs/2.5/html/config/pncconf.html
[16:26:26] <skunkworks> I have never used it. but it might make things easier
[16:27:31] <archivist> Tom_itx, the ones I have are old so no idea
[16:28:48] <Nick001-Shop> thanks - keep me reading for a while. Hoping not to smoke a third H-bridge
[16:28:50] <Tom_itx> the ones we did were like 1/2 to 3/4" plate with a 2 or so deg relief angle
[16:28:58] <Tom_itx> maybe a bit more
[16:29:18] <Tom_itx> then the edge was maybe .1" or so to allow for resharpening
[16:37:36] <archivist> also depends if the edges are set up to shear like scissors or all the edge at the same time
[16:38:36] <Tom_itx> yeah
[16:38:44] <Tom_itx> these were punched
[16:39:00] <Tom_itx> they had cork in the bottom to pop the part out
[18:22:20] <Jymmm> JT-Shop: what did you pwr cycle?
[18:24:39] <Jymmm> a riddle... "How do you tell if a knife is good enough to save your life?"
[18:25:07] <Tom_itx> do tell
[18:26:17] <Jymmm> It can easily open one of those damn clam shell packages!
[18:27:30] <Jymmm> http://www.momlogic.com/2010/12/how_to_open_fing_clamshell_pac.php
[18:27:36] <Tom_itx> u saw the ipod one didn't you?
[18:27:43] <Jymmm> nuh uh
[18:28:17] <Tom_itx> I changed my iPod's name to Titanic. It's syncing now.
[18:28:42] <Tom_itx> I know a guy who's addicted to brake fluid. He says he can stop any time.
[18:28:46] <Jymmm> rimshot
[18:33:17] <jthornton> Jymmm, turn everything off then back on
[18:33:27] <Jymmm> JT-Shop: oh, heh
[18:33:57] <Jymmm> jthornton: Hey, have you ever had possum?
[18:34:12] <jthornton> no, but Brent eats it
[18:34:19] <Jymmm> brent?
[18:34:26] <jthornton> that and coon
[18:34:40] <jthornton> he is a friend that rent's Dad's house from me
[18:34:48] <Jymmm> ah
[18:35:07] <Jymmm> you have to ask him if he's ever had Beaver Butt Juice some time.
[18:36:12] <jthornton> he's not much of a connoisseur of the fine cuisine like epicurean delights
[18:36:31] <Jymmm> jthornton: you have to ask him if he's ever had Beaver Butt Juice some time. It's a natural sweet rasberry flavoring http://en.wikipedia.org/wiki/Castoreum#Food_use
[18:36:41] * jthornton is off to hydes
[18:37:31] <Jymmm> apprved by the FDA
[18:47:40] <Tom_itx> gawd those reprap guys are set in their ways
[19:50:26] <r00t4rd3d> #reprap
[19:50:35] <r00t4rd3d> call them all losers
[19:51:08] <alex4nder> haha
[19:51:10] <alex4nder> why?
[19:51:15] <alex4nder> cuz they can't print wooden guns?
[19:51:16] <jdh> why
[19:51:44] <Jymmm> I can print wooden guns
[19:51:53] <Tom_itx> i can burn wooden guns
[19:52:14] <Tom_itx> they're sure not open to ideas
[19:53:17] <r00t4rd3d> you wanna try stuff with them?
[19:53:53] <Tom_itx> i was mildly interested in what they're up to
[19:53:53] <r00t4rd3d> dont be too aggressive, it will turn them off
[19:54:05] <Tom_itx> i'm not worried about that
[19:54:29] <r00t4rd3d> just take it easy, one finger at a time
[19:54:40] <Tom_itx> start with the middle one?
[19:54:53] <r00t4rd3d> or your big toe what ever

[21:41:50] <ReadError> fiberglass
[21:41:52] <r00t4rd3d> oh
[21:42:04] <Jymmm> ReadError: LOL good luck with using rit for that =)
[21:42:06] <r00t4rd3d> your going to crash and crack it
[21:42:16] <ReadError> Jymmm, alot of knife makers do it
[21:42:19] <ReadError> on g10 scales
[21:42:29] <ReadError> r00t4rd3d, its strong stuff
[21:42:35] <ReadError> plus, 12x24" is only 20$
[21:42:39] <ReadError> i can make new parts easy
[21:42:45] <r00t4rd3d> comes in sheets?
[21:43:10] <r00t4rd3d> where you get that at?
[21:43:20] <Jymmm> knife maker son what amterial?
[21:43:26] <Jymmm> material
[21:43:41] <ReadError> r00t4rd3d, amazon
[21:43:48] <ReadError> i can ordered color but i cant find the dang site

[21:44:30] <ReadError> g10
[21:44:40] <Jymmm> fiberglass on a knife?
[21:45:07] <ReadError> yea g10 is super rugged stuff
[21:45:16] <ReadError> phenolic resin
[21:45:16] <Jymmm> for what?
[21:45:27] <Jymmm> phenolic is not fiberglass
[21:45:58] <ReadError> well thats what it is
[21:46:02] <ReadError> phenolic resin sheet
[21:46:08] <ReadError> but its glassish?
[21:46:12] <ReadError> im not sure
[21:46:44] <Jymmm> there is linen and paper phenolic, I have paper phenloic, and yes rit can dye that. but what I have can handle 1600F+
[21:47:43] <Jymmm> there is a newer material they are using now for handles
[21:48:02] <Jymmm> cant dye it though
[21:48:12] <ReadError> http://www.amazon.com/Sheet-MIL-I-24768-Natural-Thick-Length/dp/B003SLF01C/ref=sr_1_1?ie=UTF8&qid=1345257390&sr=8-1&keywords=g10+sheet
[21:48:14] <ReadError> that stuff
[21:50:19] <ReadError> i love the stuff
[21:50:40] <Jymmm> what thickness
[21:51:43] <ReadError> what i just cut was 2 pieces of 0.093
[21:51:55] <ReadError> and some 0.062
[21:52:06] <Jymmm> ok, there is glass, paper, canvac, and linen
[21:52:06] <ReadError> but i have some .125" stuff too
[21:52:15] <Jymmm> canvas
[21:52:49] <Jymmm> what size pieces?
[21:53:57] <ReadError> those, are like ~11"x4.85 on the largest
[21:54:10] <ReadError> but i buy it by 12x24"
[21:54:18] <ReadError> amazon prime, 2 days ;)
[21:54:56] <Jymmm> and use it for what?
[21:55:25] <ReadError> i make quad frames out of it
[21:55:31] <ReadError> multirotor frames
[21:56:14] <ReadError> http://dl.dropbox.com/u/25091878/Photo%20Jul%2024%2C%208%2055%2012%20PM.jpg
[21:57:06] <Jymmm> thats a lot of battery packs
[21:57:31] <ReadError> oh
[21:57:34] <ReadError> those are speed controllers
[21:57:37] <Jymmm> or are those speed controls
[21:57:39] <Jymmm> heh
[21:57:39] <ReadError> yea
[21:58:19] <ReadError> this new frame, will have 12 motors im guessing
[21:58:27] <Jymmm> move them closer to the motors, then use the frame for a ground
[21:58:34] <ReadError> 6 arms, 2 motors per arm
[21:58:39] <ReadError> grounded to battery
[21:58:44] <Tom_itx> what uses .scad files?
[21:58:49] <ReadError> plus, g10 isnt really conductive
[21:59:14] <Jymmm> i see shiny aluminum?
[21:59:28] <ReadError> i gotta ground to battery
[21:59:33] <ReadError> wont work otherwise
[21:59:49] <Jymmm> I mean the power source to the spd ctrl
[21:59:54] <ReadError> plus more mass on the outside, kills its responsiveness
[21:59:59] <Jymmm> ah
[22:00:41] <ReadError> https://www.dropbox.com/s/bfmjcy6plr9qqv5/Photo%20Jun%2026%2C%2010%2006%2032%20PM.jpg
[22:00:46] <ReadError> thats the power distribution
[22:01:07] <Jymmm> run the three wires IN the tubing
[22:01:17] <ReadError> i could yea
[22:01:25] <ReadError> but it would require more wire, more mass
[22:01:43] <Jymmm> its there anyway, just less wind drag
[22:01:46] <Jymmm> drag
[22:02:13] <Jymmm> mnt spd ctrl near the end of the tube under the pcbs
[22:02:14] <ReadError> well this one im building
[22:02:19] <ReadError> is more for stability
[22:02:24] <Jymmm> k
[22:02:25] <ReadError> for doing good aerial video work
[22:02:37] <ReadError> the little one i do the fancy flying with ;)
[22:03:36] <Jymmm> how loud?
[22:04:18] <ReadError> pretty quiet actually
[22:04:28] <ReadError> with my setup, i can fly ~3.5km away
[22:04:34] <ReadError> and still maintain video and control
[22:04:49] <Jymmm> flight duration per charge?
[22:04:49] <ReadError> if i amplified my radio transmitter
[22:05:00] <ReadError> i could do ~10-15km easy
[22:05:16] <ReadError> if i have 1 battery ~15 mins
[22:05:27] <ReadError> but if i do a 2 in parallel, ~25
[22:05:42] <ReadError> this new one, i should be able to get over 30-40
[22:05:47] <ReadError> with the battery system im using
[22:06:12] <Jymmm> carbon fiber =)
[22:06:17] <ReadError> i have video goggles
[22:06:20] <ReadError> so i put them on
[22:06:27] <ReadError> and see everything first person
[22:06:53] <Jymmm> =)
[22:13:38] <r00t4rd3d> read you know any place that has quadcopter frame plans?
[22:15:20] <ReadError> i can send you mine
[22:15:27] <ReadError> already gcoded
[22:15:29] <ReadError> if you want
[22:15:40] <ReadError> or the visualmill and solidworks
[22:15:46] <ReadError> but nah i havnt run across much
[22:16:24] <r00t4rd3d> how big is yours?
[22:16:28] <r00t4rd3d> looks huge
[22:24:01] <ReadError> r00t4rd3d,
[22:24:04] <ReadError> my quads
[22:24:07] <ReadError> arent that big
[22:24:29] <Jymmm> Man, I really dislike AAA batteries
