[01:05:59] <Gensor> what is the cost of changing a bridgeport from 3phase to 1phase?
[01:09:43] <Tom_L> a transformer
[01:10:06] <Gensor> somewhere under a $1000?
[01:10:27] <Tom_L> not sure
[01:10:27] <Tom_L> never had to get one
[01:10:57] <toastydeath> how are you doing it
[01:10:57] <Tom_L> you don't want to use a phase inverter?
[01:11:32] <Gensor> you got me... that is why I am asking
[01:11:41] <toastydeath> manual bridgeports don't give a shit about how clean the power is and will run off an RPC
[01:11:48] <toastydeath> which are largely a homebrew item
[01:13:05] <Gensor> bridgeport interact
[01:13:45] <Gensor> what is an rpc
[01:13:53] <Tom_L> don't use me as a last word here but my bud started out his shop using a phase inverter
[01:13:59] <Tom_L> and depending on how many machines he had on, he would change the tap on it
[01:14:58] <Tom_L> JT-Shop, i think i got things working here finally. mapped all my selector switches and mpg and tested it. got output on all axis
[01:14:58] <Tom_L> woot!
[01:15:01] <Gensor> Im assuming the cheapenst route would be to use a VFD on the spindle and try to rewire the other circuitry for 220v
[01:15:09] <toastydeath> vfd is the most costly option
[01:15:34] <Gensor> tom: good for you!
[01:15:50] <Tom_L> i'm thinking a phase inverter might be the cheapest route
[01:16:00] <toastydeath> rotary phase converter is the cheapest
[01:16:12] <toastydeath> since it uses a cheap 3ph motor
[01:16:15] <Tom_L> i'm not sure how it's done but you can make one from an old motor
[01:16:28] <toastydeath> if you have a 1 hp bridgeport, you need a 2 hp motor
[01:16:36] <Tom_L> converter*
[01:16:38] <toastydeath> 5 hp sprindle, 10 hp motor
[01:17:07] <toastydeath> VFDs that will take 1ph and spit out 3ph are expensive in any actual size

[01:18:29] <Gensor> thanks for the info
[01:18:38] <toastydeath> industria/commercial cnc gear is very intolerant of power problems
[01:18:51] <toastydeath> and most rpcs have power problems of varying descriptions
[01:19:05] <toastydeath> voltage imbalance being prime among them
[01:19:22] <Gensor> If you see a bridgeport interact for under 3000, please let me know!

[01:19:34] <Tom_L> 10Hp
[01:21:08] <Tom_L> don't they need a load to work?
[01:21:12] <Tom_L> i can't remember
[01:23:43] <Tom_L> we ended up changing the transformer in a Fadal because it didn't like the converter
[01:23:47] <Connor> I've hear of.. or seen, someone use a 2nd 3-phase motor to provide the 3rd phase..
[01:24:06] <Tom_L> the old bridgeport boss5 and tracer worked fine
[01:25:32] <toastydeath> Connor, that is what is being discussed
[01:26:35] <Connor> oh, sorry... didn't read far enough up.

[02:12:51] <willburrrr2003> any Idea what it should be, or what it is trying to do? the routine came with ngc under the testsuite folder...possibley just a mill function instead of a lathe function?

[02:17:01] <toastydeath> where does emc define user defined codes
[02:17:05] <willburrrr2003> the backlash.ngc was in with the mill fioles, so possibly in its sample ini is the m110 setup
[02:17:23] <willburrrr2003> I would assume in the ini file?
[02:19:19] <toastydeath> does it call some function
[02:19:22] <toastydeath> or is it blank
[02:19:33] <willburrrr2003> don't see it in the ini....hmmm will have to read up on it
[02:20:34] <willburrrr2003> i am thinking it is a custom M-code function having to do with a 1" dial indicatior, since that is what the routing uses for the backlash measuring in the function

[12:17:04] <SWPadnos> ok
[12:17:13] <SWPadnos> I was going to say, F is irrelevant for G0 moves
[12:17:22] <Tom_itx> the rapids have a much smoother acceleration curve
[12:17:46] <SWPadnos> and you changed the maxvel setting in the ini file to change G0 speed?
[12:17:51] <Tom_itx> and i probably could have gone well past F300 on them
[12:17:59] <Tom_itx> set with the slider in emc
[12:18:07] -!-
ries [ries!~ries@200.125.129.54] has joined #emc
[12:18:14] <SWPadnos> which slider?
[12:18:20] <Tom_itx> i don't have it on atm
[12:18:21] <Tom_itx> sry
[12:18:25] <SWPadnos> ok
[12:18:30] <Tom_itx> gotta leave in a few
[12:18:50] <Tom_itx> iirc it was max velocity
[12:18:57] <SWPadnos> hmm
[12:19:08] <Tom_itx> and i was curious why it overrode the file settings
[12:19:26] <SWPadnos> it do4esn't
[12:19:28] <SWPadnos> err
[12:19:30] <SWPadnos> -4
[12:19:38] <Tom_itx> i'll check all the settings later today
[12:19:43] <Tom_itx> and have better info
[12:19:58] <SWPadnos> the only slider that I'm aware of, which affects G0, is one that may reduce the G0 speed
[12:20:03] <SWPadnos> not increase
[12:20:18] <Tom_itx> well there's one that maxd out around 600
[12:20:28] <Tom_itx> i moved it down to about halfway
[12:20:51] <Tom_itx> i forget what it was called but it was the bottom slider mdi
[12:20:56] <SWPadnos> well, I don't know what's going on, but I suspect it isn't what you expect :)
[12:21:01] <Tom_itx> default emc screen
[12:21:26] <Tom_itx> i'm not expecting anything yet, just trying to figure out the settings
[12:21:54] <jthornton> did you use the StepConf Wizard to generate your config?
[12:21:59] <Tom_itx> no
[12:22:17] <Tom_itx> the default stuff for the mesa boards
[12:22:41] <jthornton> oh, I forgot you have a mesa board
[12:22:51] <Tom_itx> i've got time to post the hal and ini files then i probably gotta go
[12:23:07] <jthornton> I've got to head out too
[12:23:23] <jthornton> do you know your stepper drive timing ?

[12:23:56] <SWPadnos> see you later
[12:24:34] <Tom_itx> 10µs
[12:24:38] <Tom_itx> on the pulse
[12:24:58] <Tom_itx> default was 40 with the default file
[12:25:10] <Tom_itx> my old controller had it around 6µs
[12:26:00] <jthornton> so really knowing the drive timing you just need to work out the max rpm and acceleration
[12:26:58] * jthornton heads out
[12:27:07] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/emc/

[12:30:20] <Tom_itx> jthornton, ya.. if you're a math whiz
[12:31:56] <Tom_itx> figuring the table mass and what it takes to move it isn't something i'm used to doing on a regular basis
[12:36:40] <anonimasu> Tom_itx: trial and error works best
[12:37:46] <anonimasu> set your maxvel sanely high and try increasing your accel until it stalls

[13:08:21] <archivist> Valen, how many times, eg production or 10 off, there are books on press tool design and forces
[13:08:45] <archivist> or is this robot wars
[13:09:12] <anonimasu> Valen: it's not too heavy
[13:09:22] <anonimasu> it's a matter of applying hooke's law
[13:09:40] <anonimasu> and you need to apply force to a point that exceeds the material you want to punc's shear force
[13:09:48] <Valen> robot wars
[13:10:02] <anonimasu> while keeping the force on the tool by material choice under the strain limit
[13:10:10] <Valen> a spinning disk is hitting an angled plate of armor
[13:10:15] <anonimasu> Valen: cobalt is kind of brittle...
[13:10:23] <Valen> we want the tooth sticking out of the disk to bite in to the armor
[13:10:34] <anonimasu> you want a steel with a high modulus of elasticity and a high toughness
[13:10:50] <Valen> doesn't have to punch through (though that is cool) but it must grab
[13:11:07] <Valen> thing is the armor is these days high hardness steels
[13:11:22] <anonimasu> got numbers?
[13:11:38] <anonimasu> you need a toigher steel to punch through them
[13:11:40] <anonimasu> tougher...
[13:12:18] <anonimasu> brittle might do, but it probably wont survive the moment after
[13:12:32] <Valen> chrome://downloads/home/jake/Downloads/Bisplate_400.pdf
[13:12:42] <Valen> doesn't need to survive too many rounds
[13:13:03] <anonimasu> err that's a local file
[13:13:11] <Valen> duh sorry
[13:13:23] <Valen> http://www.bisalloy.com.au/files/Bisplate_Pdfs/Bisplate_400.pdf
[13:13:23] <anonimasu> how thich?
[13:13:25] <anonimasu> thick
[13:13:29] <Valen> stoopod chrome
[13:13:31] <Valen> varies
[13:13:38] <Valen> 3mm is standard
[13:13:50] <anonimasu> holy crap.
[13:13:55] <anonimasu> punching that will be heavy.
[13:14:46] <Valen> currently its achieved with a ~1m titanium bar spinning at 3000RPM with 2x 500 gram S7 tool steel teeth hanging off it
[13:15:10] <anonimasu> i think that's as good as it gets
[13:15:47] <anonimasu> what's the problem with the current design?
[13:16:00] <Valen> doesn't do as much to the biz
[13:16:05] <Valen> just scrapes off it
[13:16:09] <Valen> doesn't bite in
[13:16:42] <anonimasu> you need a force down into the floor i gues
[13:16:43] <anonimasu> s
[13:17:08] <anonimasu> the force you can give with that configuration is only angular momentum
[13:18:23] <anonimasu> I'd say to pierce that you need a hammer...
[13:18:38] <Valen> http://www.youtube.com/watch?v=H36YjKvsTe8
[13:18:47] <Valen> the goal isnt to punch a hole through them
[13:18:55] <Valen> its not going to work
[13:19:12] <anonimasu> well, if you want to hook to them that is how it'll have to work
[13:19:46] <anonimasu> cant make anything attach to a flat surface
[13:21:16] <anonimasu> just my 5c
[13:21:18] <pcw_home> suction cup?
[13:21:30] <Valen> when people used mild steel for armor it would dig in
[13:21:35] <Jymmm> crazy glue + acetone
[13:21:47] <Valen> http://www.youtube.com/watch?v=_m5Hi9cjajo&feature=related this is a competition that would be nice to win
[13:23:15] <anonimasu> pcw_home: indeed but where to get vaccum from :)
[13:24:27] <anonimasu> Valen: how does the tooth look?
[13:24:44] <jdhNC> anyone ever seen a paxtonpatterson cnc'ed sherline mill or lathe?
[13:24:51] <anonimasu> _\ ?
[13:25:09] <anonimasu> can you get it below them?
[13:25:55] <Valen> current tooth design
http://www.robowars.org/forum/viewtopic.php?t=74
[13:26:02] <Valen> not my bot, but a good indicator
[13:26:19] <anonimasu> I see..
[13:26:28] <anonimasu> you would need alot more point to make damage..
[13:26:30] <anonimasu> or hook
[13:27:06] <anonimasu> simply you cant get enough force on that point to dig in...

[14:02:23] <anonimasu> I doubt you really do have that kinetic energy becaust it would defenetively pierce
[14:03:09] <Valen> well you can do the maths your self
[14:03:23] <anonimasu> also you have tungsten tip on thoose

[14:03:58] -!-
Valen has quit [Quit: Leaving.]
[14:05:06] <anonimasu> and last of all surface area...
[14:05:09] <anonimasu> -_-
[14:07:00] <pcw_home> I can see the momentum possibly, but nowhere near the KE as a bullet (KE proportianal to velocity ^2)
[14:08:06] <jdhNC> almost 1km/sec
[14:10:17] <skunkworks> http://www.youtube.com/watch?v=qrFEmTnMzV8
[14:10:51] <pcw_home> both the shooter and the target get the same momentum but the target gets the KE (in ratio of square of gun/bullet mass I think)
[14:11:40] <jdhNC> 18000 j, better to not be the recipient
[14:11:51] <The_Ball> skunkworks, recycled parts, sweet

[14:12:34] <The_Ball> I really like the RC servo Z servo
[14:14:03] <anonimasu> anyway it dosnet matter as the impact depends on the surface area of the hammer

[14:14:31] <anonimasu> so unless they have a sharp tip they wont have nowhere near the n/mm^2 they need to penetrate or make anything
[14:15:24] <jdhNC> what provides the force?
[14:17:42] <skunkworks> cradek: exactly
[14:19:37] <Loetmichel> anonimasu: but a hammer has a much bigger mass than a bullt
[14:19:42] <Loetmichel> bullet
[14:20:10] <Loetmichel> and if the hammer has a fin it will have LESS iimpact area than a blunt bullet
[14:20:11] <elmo401> the force is provided by the velocity.
[14:20:14] <elmo401> and the mass
[14:20:29] <elmo401> raise either one and you increase impact
[14:20:58] * Loetmichel had schot a .45 colt peacemaker faksimilie
[14:21:01] <anonimasu> their hammer dosent
[14:21:11] <anonimasu> it has a \/ notch with a long sharp tip

[16:37:44] <Connor> and of course, your in NC now.. hence your nick on IRC
[16:38:13] <jdhNC> yeah, I'm not so creative (my usual jdh was taken)
[16:38:36] <Connor> I've went by Connor for years and years.
[16:38:48] <Connor> Very rare that I don't get it..
[16:39:24] <jdhNC> the jdh that is registered here might be be, but I don't remember
[16:39:31] <jdhNC> err... might be me.
[16:40:46] <nullie> Connor, error was "all joints must be homed before going into teleop mode"
[16:41:10] <Connor> how many Axis do you have and how many does EMC say ?
[16:41:10] <jdhNC> I've seen that message and never knew what it meant
[16:41:26] <jdhNC> everything still worked though and I have no idea what teleop mode is
[16:41:44] <nullie> Connor, it's three axis, with two motor on X axis
[16:42:06] <nullie> Connor, config defines seven axes though
[16:42:13] <Connor> Ay, yea.
[16:42:16] <Connor> there is your issue.
[16:42:28] <Connor> you need to change the line in EMC file to only have XYZ
[16:42:31] <Connor> or XXYZ
[16:42:41] <nullie> hm, hever though about XXYZ

[16:45:00] <Connor> http://www.linuxcnc.org/docview/html/config_ini_config.html#sub:[TRAJ]-section
[16:47:09] <Connor> Which are you calling your X and which are you callling Y ?
[16:47:25] <Connor> X should be side to side, Y is back and forth, and Z is up and down..
[16:47:46] <Connor> Double motor's are normally on Y for the gantry.
[16:48:02] <Connor> When I started out, I got my X and Y backwards..
[16:48:08] <Connor> but, that's all fixed now. :)

[18:34:36] <Tom_itx> you could also use double back tape
[18:35:37] <skunkworks> some sort of syphon device? fast moving air causes a vaccum? (sort of like a venturi?)
[18:35:46] <Tom_itx> i would set the board against 3 dowel pins for alignment and stick it down with double sideed tape
[18:36:02] <Tom_itx> we used a vacuum pump
[18:36:23] <JT-Shop> I use Piab for vacuum
[18:36:25] <skunkworks> I have had good luck with a vaccum pump - but ours is a 1hp vane type - works freat

[18:40:58] <Loetmichel> yes, very much ;-)

[18:41:39] <Loetmichel> didn't need
[18:41:54] <Tom_itx> keep in mind, if you use coolant it will suck that into the pump as well

[18:44:31] <Tom_itx> and fall apart
[18:44:36] <Loetmichel> yes
[18:45:19] <Loetmichel> but to mill carbon and glass fibre and wood and Engrave pcbs you dont need coolant ;-)

[20:21:03] <Tom_itx> i should add some to the pendant
[20:21:18] <JT-Shop> took me a year to figure it out but I never did a chap on the forum found something a chap in europe had done and I fixed it so it stays in sync with Axis
[20:23:35] <Tom_itx> too much 'cleaning' being done around here atm for me to get anything done
[20:26:30] <JT-Shop> crap, tornado watch to the south of us
[20:26:48] <Tom_itx> just keep it over there is all i ask

[21:07:43] <FinboySlick> I'm all bummed out. I had some pretty consistant > 7000us jitter when I tested this box with the livecd. Not so after the install. Enabling APIC in the bios makes things better. I'm pealing off the wiki but if anyone has hints I'd be grateful.
[21:14:43] <skunkworks> what is the jitter after install?
[21:15:10] <FinboySlick> about 18000
[21:15:53] <FinboySlick> There was a cheapo onboard RAID controller that really killed things so I disabled that, disabled audio, etc.
[21:16:12] <e3m> hello my new retrofit:
http://frezowanie-toczenie-cnc.pl/cnc/
[21:17:03] <FinboySlick> skunkworks: there's an nvidia card in there, but I'm using nouveau... It was there when I tested off of the livecd too.
[21:21:41] <FinboySlick> I think I have a PCI G200 somewhere, I guess I could try that.

[23:19:26] <ssi> I'm having a hard time debugging this code I'm writing, because it seems like maybe it has an infinite loop in it
[23:19:34] <ssi> and emc doesn't handle it gracefully... it just hangs
[23:21:30] <JT-Shop> not much handles infinite loops well
[23:22:02] <SWPadnos> how could it tell before the end of time? :)

[23:41:05] <FinboySlick> Okay, I got it down to a pretty steady < 6500 *unless* I go to the appearance control panel. So I'm guessing what's left is random video card burps.
[23:41:12] <JT-Shop> Tom_itx: there are a couple of gotcha's with pause/run
[23:41:52] <JT-Shop> one is what to do and that is fairly straight forward... if running and button pressed pause... if paused and button pressed resume
[23:42:14] <JT-Shop> the hard one was the racetrack condition when the button is pressed
[23:43:06] <JT-Shop> Anders Wallin had a nice bit of code for that part... I just added the first part to his part and have a very well behaved pause/run button on the CHNC now
[23:43:57] <JT-Shop> the key I missed was toglle2nist
http://www.linuxcnc.org/docview/html/man/man9/toggle2nist.9.html
[23:44:06] <JT-Shop> toggle2nist
[23:44:35] <JT-Shop> FinboySlick: let it run a while to be sure
[23:46:07] <JT-Shop> toggle2nist is one that I never understood and there is 0 documentation on it to explain what it does so I promptly forgot about it
[23:46:34] <FinboySlick> JT-Shop: Yeah.

[23:49:29] <JT-Shop> no wonder awallin knows how it works he wrote it lol
[23:53:39] <Tom_itx> undocumented code is like no code at all
[23:54:46] <JT-Shop> can you make any sense of the comp?
[23:56:26] <JT-Shop> I think this is the key /* reset pins when we see the desired state */
[23:56:27] <JT-Shop> on will be only on for 1 or 2 cycles at the most
[23:56:27] <Tom_itx> if it doesn't match, find the state and toggle it
[23:56:52] <Tom_itx> that's the else condition
[23:56:57] <Tom_itx> if there wasn't a toggle
[23:57:19] <Tom_itx> if in != old_in... else
[23:57:33] <Tom_itx> the else is that in = old_in
[23:58:22] <Tom_itx> and if in that case it is on, turn it off
[23:58:41] <JT-Shop> I'll attempt to add some comments to it in the AM
[23:58:48] <Tom_itx> :)
[23:58:59] <Tom_itx> that code is relatively easy to follow
[23:59:05] <JT-Shop> yea
[23:59:36] <Tom_itx> it's the 'where it applies' that needs comments
[23:59:40] <JT-Shop> I think the is_on is the key to this working like it does
