[00:06:46] <alex_joni> http://FantasticContraption.com/?designId=333966 <- the first one I did worked better
[00:07:13] <jmkasunich> I still can't open that kind of url
[00:07:32] <fenn> this reminds me of http://phun.at/
[00:09:55] <alex_joni> jmkasunich: I found that it's quite fun to look at other designs
[00:11:13] <alex_joni> hmm.. rope bridge is pretty smart
[00:27:55] <jmkasunich> arg
[00:28:08] <jmkasunich> firefox crashed before I finished the last leve
[00:28:09] <jmkasunich> l
[00:28:19] <jmkasunich> thats probably a good thing
[00:28:25] <jmkasunich> * jmkasunich gets away from the computer
[01:10:44] <jmkasunich> it annoys me when people lie with numbers
[01:11:22] <jmkasunich> I got some junk mail from my bank today: "did you know that if everybody in the US used online bill payment there would be 1.45 billion tons less waste peper?"
[01:11:29] <jmkasunich> lies!
[01:12:27] <jmkasunich> 1.45 billion tons / 300 million people = 9666 lbs of paper per person per year
[01:12:39] <jmkasunich> NFW
[01:12:57] <jmkasunich> maybe if you combined all the junk mail, but not bills
[01:35:05] <jmkasunich> heh, came at umpossible a fresh way and solved it in 10 mins
[02:24:04] <cradek> the lathe has a PC in it!
[02:24:13] <cradek> downloading hardy now...
[02:24:20] <JymmmEMC> jmkasunich: mail them back... "Did you know that if you didn't send this out in the first place you would have saved 3 billions tons?"
[02:24:31] <jmkasunich> you mounted it in the old control cabinet?
[02:24:54] <cradek> I was able to make room in one of the boxes on the lathe itself. I will be able to get rid of the control cabinet.
[02:25:19] <cradek> I have a new box (old phone system case) that the servo drives and transformer will (barely) fit in.
[02:25:25] <jmkasunich> "PC" = the computer only, or the monitor and kb?
[02:25:42] <cradek> PC = power supply, hard disk, motherboard
[02:26:06] <cradek> there is room leftover to mount the mesa stuff, and the original wiring for most everything will reach it.
[02:26:36] <cradek> looks like I will have a lot going this weekend.
[02:27:37] <cradek> the coolant motor is 3 phase. Is there a simple way I can drive it with one phase (add a cap somehow?)
[02:28:23] <jmkasunich> "static phase converter" = a cap (or two)
[02:28:38] <jmkasunich> I'm not sure how it gets hooked up, or how much C you need
[02:28:53] <cradek> do you leave them hooked up all the time, or just to start it?
[02:29:13] <jmkasunich> all the time I think, or maybe you have a larger start C, and a smaller run one
[02:29:34] <cradek> ok thanks, I'll ask the internet (later)
[03:31:51] <cradek> os and updates installed!
[03:32:02] <cradek> yay, I'm committed
[05:04:24] <a-l-p-h-a> muahaha

[13:58:18] <ChanServ> [#emc] "This is the #emc channel - talk related to the Enhanced Machine Controller and general machining. Website: http://www.linuxcnc.org/, wiki at http://wiki.linuxcnc.org/"
[14:27:17] <JymmmEMC> SWPadnos: ping
[17:00:17] <Roguish> Morning all. Gcode question: I have an X,Z,C mill (sort of a vertical turret lathe or a horizontal mill with a rotary C table) with the tool in the -X direction. I want to use a tool table for tool offsets. how do I use G43 with the lathe format tool table to get the X tool length offset?
[17:01:30] <Roguish> I see that G43.1 (dynamic tool offset) uses I or K to indicate X or Z. Is that applicable in G43?
[17:05:38] <Roguish> How do I get the 'lathe' tool table to work with a straight G43?
[17:10:50] <jepler> Roguish: just write your tool table entries in the lathe format
[17:11:09] <jepler> it's G43 for both formats of tool table entry
[17:12:11] <Roguish> ok, so a 0 (zero) in the z offset and my real number in the x offset? and call G43?
[17:12:32] <Roguish> with the other stuff in the lathe tool table.
[17:13:29] <Roguish> oh, thanks for responding. my client has already broken 1 expensive tool and does not want to break any more.
[17:17:06] <Roguish> jepler: see this of the machine: http://www.youtube.com/watch?v=KT_cAiyks5U
[17:18:17] <jepler> well .. test first
[17:18:36] <Roguish> heck yeah.
[17:18:48] <Roguish> they got a bit ahead of me.
[17:19:46] <Roguish> machine foam of different sorts. the cutters are generally .50 diam, 12" long, carbides, 2 flute spirals. kinda pricey.
[17:20:44] <jepler> sounds interesting -- I can't watch the video on this machine though
[17:21:51] <Roguish> check it out sometime. i added it to the emc group.
[17:22:25] <Roguish> they now want to change their gantry machine from flashcut to emc2.
[17:23:52] <JymmmEMC> hey LawrenceG wanna help me crack a safe?
[17:37:51] <LawrenceG> JymmmEMC, sounds like fun... a new product line for me..
[17:38:08] <JymmmEMC> LawrenceG: I'm actually serious.
[17:38:29] <JymmmEMC> LawrenceG: I have a digital safe I was given without the combination.
[17:39:18] <JymmmEMC> LawrenceG: The external keypad also houses (most) of the electronics and I've been able to take apart
[17:40:25] <JymmmEMC> LawrenceG: I just need some help with bypassing the electronics on it, specifically the microcontroller.
[17:45:48] <LawrenceG> hmmmm.... no idea
[17:46:45] <JymmmEMC> LawrenceG: There are three wires going into the safe. One is common with GND to the battery.
[17:46:54] <LawrenceG> send it to BigJohnT and let him try plasma
[17:47:13] <BigJohnT> MORE POWER
[17:47:15] <LawrenceG> any idea what is inside ?
[17:47:28] <JymmmEMC> No, I'm trying NOT to damage the integrity of the safe itself.... it's a data safe
[17:47:37] <micges> hi all
[17:47:49] <LawrenceG> greetings from the North
[17:47:50] <JymmmEMC> I can get into it easily if I had to, that's nto my intension.
[17:48:09] <JymmmEMC> LawrenceG: No idea, complete black box at this point.
[17:48:56] <JymmmEMC> LawrenceG: I'm assuming that there *MIGHT* be a "reset" button to clear/reset the combination, but I'm not sure as I don't have the instruction manual for it yet.
[17:49:30] <JymmmEMC> LawrenceG: Applting 5VDC to the other two wires does nothing.
[17:50:25] <LawrenceG> no clue here... depends on how hacker proof the designer was trying to make it....
[17:50:59] <JymmmEMC> LawrenceG: Not very... I've been able to bypass the 2 second delay, and the 5 minute lockout already.
[17:51:06] <LawrenceG> If you had another one that was open, it would be much faster to explore
[17:51:14] <JymmmEMC> LawrenceG: Well... DUH!
[17:52:22] <anonimasu> :)
[17:52:27] <anonimasu> jymm: trying to crack it?
[17:52:38] <LawrenceG> if built for the NSA, putting 5v on one wire would open it, and 5 volts on the other wire would set off a pile of thermite, melting everything into a blob!
[17:53:00] <JymmmEMC> anonimasu: yeah, but without damaging it =)
[17:53:55] <anonimasu> hm.. if it was a normal lock it'd be easier ^_^
[17:54:08] <anonimasu> better get guessing
[17:54:10] <LawrenceG> the only safe I played with was a huge jewelers safe, it even with the combination, it was a bear to get open
[17:54:27] <anonimasu> :)
[17:54:43] <JymmmEMC> http://upload.wikimedia.org/wikipedia/commons/e/ec/FireKing_KV2015-2_safe,_class_350-2R_combo_panel.JPG
[17:54:44] <cradek> at work three people know the safe combination, yet only I seem to be able to open it :-)
[17:54:55] <LawrenceG> locks only slow down the honest people
[17:54:56] <anonimasu> the shittier safes dont have that problem ;)
[17:55:18] <JymmmEMC> anonimasu: this is the shitter one, but has a UL Listed 2hr fire rating
[17:55:45] <anonimasu> jepler: no chance to get a code?
[17:55:47] <anonimasu> or did you find it?
[17:56:12] <anonimasu> http://commons.wikimedia.org/wiki/Image:FireKing_KV2015-2_safe,_class_350-2R_door_opened.JPG
[17:56:13] <anonimasu> heh
[17:56:27] <anonimasu> hello beast.
[17:56:55] <JymmmEMC> anonimasu: but see that lil hole there... not sure what it is
[17:57:02] <JymmmEMC> could be a reset button
[17:57:46] <anonimasu> I cant see it
[17:58:00] <JymmmEMC> straight down, on the inside fo the door
[17:58:27] <anonimasu> ah yes
[17:58:36] <anonimasu> I wonder how they open them if they've been through a fire..
[17:58:45] <JymmmEMC> plasma cutter =)
[17:59:01] <anonimasu> heh
[17:59:03] <anonimasu> yeah
[17:59:04] <anonimasu> zwoop
[17:59:21] <BigJohnT> DynooooMite!
[17:59:21] <JymmmEMC> it's no burglary rated, just fire rated.
[18:00:02] <JymmmEMC> The UL impact test calls for the safe to be heated to 1638° for 45 minutes, then dropped onto concrete rubble from a height of 30 feet, then inverted and reheated for another 45 minutes.
[18:00:37] <anonimasu> google dosent know how to open it
[18:00:43] <JymmmEMC> nope
[18:00:50] <anonimasu> did you try alot of combinations yet?
[18:01:00] <JymmmEMC> the most common ones
[18:01:08] <anonimasu> fingerprint powder would have been a approach
[18:01:20] <anonimasu> isolate a few numbers
[18:02:03] <JymmmEMC> There was a barcode on the PCB. I was able to scan it and get a number, but that number or it's patterns don't open it. and doens't match the SN of the safe itself.
[18:02:32] <JymmmEMC> It might have been the original combination from the factory, but has changed since then.
[18:04:21] <anonimasu> * anonimasu nods
[18:04:49] <anonimasu> call the manufacturer and ask them if a locksmith could open it for you?
[18:04:58] <anonimasu> without exploding it ;)
[18:05:08] <JymmmEMC> Nah, no fun in that
[18:05:14] <anonimasu> or if they can open it..
[18:05:40] <JymmmEMC> There's no rush in getting it opened, and I like the challenge of it.
[18:06:08] <anonimasu> HEHE
[18:06:10] <anonimasu> ok
[18:06:31] <anonimasu> I locked a padlock to something at my desk yesterday -_-
[18:06:36] <JymmmEMC> locks have NEVER stopped me, just slow me down
[18:06:40] <anonimasu> without finding the key
[18:06:51] <LawrenceG> jymm, any idea how many numbers in the combo?
[18:06:57] <JymmmEMC> up to 5
[18:07:06] <JymmmEMC> so 100,000 possible
[18:08:08] <LawrenceG> a bunch of relays, a small program and a day or 2
[18:08:08] <JymmmEMC> If *I* knew how to interface paraport to other electronics, I could just attach the PC to the safe and let it go thru sequencially in a couple of hours.
[18:08:28] <LawrenceG> classic ladder!
[18:08:34] <JymmmEMC> sure
[18:08:34] <anonimasu> yep ;)
[18:08:37] <anonimasu> optoisolators
[18:09:41] <JymmmEMC> There are two LED's on it that I could use as feedback to say when it's found the right combination
[18:09:42] <anonimasu> http://www.fireking.com/pdf/Lost%20Key%20Replacement%20Form.pdf
[18:09:43] <LawrenceG> the devel channel was just talking about feature creep..... I dont think they though of this one
[18:09:56] <JymmmEMC> anonimasu: It's $50 and no guarntee
[18:10:07] <anonimasu> :p
[18:10:38] <JymmmEMC> If I could just find the manual, that be half the battle
[18:11:09] <anonimasu> did you try emule?
[18:11:21] <JymmmEMC> anonimasu: nope, could you?
[18:11:24] <anonimasu> no
[18:11:29] <JymmmEMC> smack
[18:11:35] <anonimasu> uh yes, I can.. actually ^_^
[18:12:41] <anonimasu> emule is good for stuff not found easily
[18:13:42] <anonimasu> jymm: it was probably easier to pick my crap padlock with the hairpin then to open your safe..
[18:14:21] <JymmmEMC> heh
[18:15:10] <anonimasu> I think smacking the lock upside down against something with a bit of tension would make it open ^_^
[18:18:32] <anonimasu> JymmmEMC: nope cant find anything
[18:18:46] <anonimasu> JymmmEMC:they probably do not exist on the net

[18:25:59] <jepler> jepler has changed the topic to: Welcome! EMC (Enhanced Machine Controller) is a linux-based opensource CNC control. | Latest release: EMC 2.2.6 | http://www.linuxcnc.org | http://wiki.linuxcnc.org
[18:28:05] <JymmmEMC> anonimasu: I don't think this one uses a silenoid, as much as a screw
[18:38:38] <anonimasu> ok
[18:43:04] <jmkasunich> well, there is one for the "chores I didn't plan on doing today" list
[18:43:17] <jmkasunich> wash the dog because he found some stinky pile-o-crap to roll in
[18:43:31] <BigJohnT> my dog loves to do that too
[18:43:43] <anonimasu> hm mine dosent
[18:43:51] <anonimasu> she does it sometimes, very very rarely
[18:43:59] <jmkasunich> my dog gets to sleep on the bed, so he can't be doing that
[18:44:06] <anonimasu> mine too :)
[18:44:16] <BigJohnT> mine sleeps behind my chair
[18:44:59] <stustev> I don't have a dog - my cat doesn't do that
[18:45:19] <jmkasunich> just one of many dog things that cats don't do
[18:45:26] <jmkasunich> otoh, dogs rarely get hairballs
[18:45:42] <jmkasunich> and my dog cleans up the cat puke
[18:45:52] <stustev> hair balls don't usually stink
[18:46:18] <BigJohnT> * BigJohnT heads out to the shop to plasma some parts out
[18:46:21] <stustev> maybe that would be a reason to get a dog
[18:50:40] <DanielFalck> stustev: hi
[18:50:55] <cradek> hi all
[18:50:57] <DanielFalck> have you been doing anything with apt360 lately?
[18:51:41] <DanielFalck> cradek: hi, how's the lathe coming along?
[18:51:57] <cradek> it is firmly beyond the point of no return
[18:52:21] <cradek> I unhooked, without labeling, the 900 wires that connected the control to the machine
[18:52:36] <jmkasunich> it is good to be committed
[18:52:46] <cradek> yes
[18:53:04] <cradek> I have a pc and its accoutrements mounted where some 70s ttl machine logic used to be
[18:53:27] <cradek> next step is to mount the mesa boards and start hooking things up.
[18:53:36] <cradek> I'll go out and do that any second.
[18:53:44] <jmkasunich> you need to take pictures
[18:53:49] <jmkasunich> * jmkasunich nags
[18:53:58] <stustev> DanielFalck: I haven't done anything for quite a while. Still hoping to get back to it. I have been trying to get EMC2 on a few machines.
[18:54:08] <cradek> I have a few.
[18:54:30] <DanielFalck> stustev: can you drop into the #cam channel for I little bit?
[19:59:43] <BigJohnT_> BigJohnT_ is now known as BigJohnT
[21:58:19] <alex_joni> good night all
[22:14:28] <jmkasunich> that's sad....
[22:14:41] <jmkasunich> in 2003, I bought a surplus 4" Kurt, less jaws
[22:14:52] <jmkasunich> on June 1 of this year I bought the jaws
[22:15:08] <jmkasunich> on August 10, I finally got around to disassembling and cleaning the vise and mounting the jasw
[22:15:10] <jmkasunich> jaws
[22:15:25] <jmkasunich> but, its done, so yay!
[22:15:56] <robin> heh good comes to those who wait
[22:16:21] <robin> got my drive hooked up to my motor now, just playing with tuning the PID loop
[22:16:32] <jmkasunich> good comes to those who don't procrastinate so much
[22:16:39] <robin> I found plenty of ways to get following errors :)
[22:17:55] <jmkasunich> only three ways to not get them
[22:18:32] <jmkasunich> 1) get it tuned right
[22:18:38] <jmkasunich> 2) set the limits really wide
[22:18:42] <jmkasunich> 3) don't turn it on
[22:18:58] <robin> option 1 sounds good
[22:19:16] <robin> i guess this is going to involve "reading"
[22:20:58] <jmkasunich> mostly reading scope traces
[22:21:11] <robin> halscope?
[22:21:13] <jmkasunich> but you might have to read docs to find out how to use the scope
[22:21:14] <jmkasunich> yeah
[22:26:08] <robin> presumably a real scope on the Aout will do similar?
[22:27:31] <robin> on the basis of I know how to drive a real scope ;)
[22:28:26] <robin> i presume the integrator manual is the place to start?
[22:41:51] <robin> hmm
[22:42:47] <robin> odd, it seems bit strange .. in one direction, monitor Aout, crank ballscrew by hand, 0.8V error input to servo amp ..
[22:42:58] <robin> crnak in other direction .. lots of volts
[23:49:38] <robin> ah, there it is .. the M5i20 setup has a MAX_OUPUT=1.0 line .. so the output goes -10.0 to +1.0
