[00:00:07] <mhaberler> then search for g84 - you'll see who changed which line
[00:00:32] <JT-Shop> I'll have to do that when I git near a git machine
[00:01:05] <mhaberler> Paul Corner, cradek, a line by jepler, zero comments why
[00:01:23] <JT-Shop> odd

[00:11:43] <mhaberler> Jt-shop: I might give it a stab but it is probably better to ask cradek why he abandoned it
[00:11:49] <mhaberler> first, i mean
[00:15:38] <mhaberler> I would assume G84 needs a K word as well
[00:16:56] <tom3p> the kins on that 2 axis eye surgery robot is cool. it orbits.
[00:16:57] <tom3p> i couldnt access the .wmv using chrome but wget snags it w/o probs http://www.tue.nl/fileadmin/content/pers/2011/10_oktober/eye_surgery_robot_vid_1_movements.wmv
[00:17:11] <tom3p> and the uni made the src open
[00:22:41] <tom3p> open using the cern open hdwr license http://www.ohwr.org/projects/cernohl/wiki ( a borg penguin icon ;)
[00:27:15] <Tom_itx> JT-Shop, google ConnectBot
[00:27:22] <Tom_itx> for ssh client
[00:27:36] <jdhNC> isnt' that android?
[00:27:43] <Tom_itx> i'm not sure
[00:28:03] <jdhNC> there are a few good ssh apps in the app store
[00:28:09] <Tom_itx> i don't have either one
[00:28:27] <Tom_itx> but rather than running irc on it i'd ssh into his server
[00:28:42] <jdhNC> I paid for two ssh apps...wish I could give them away or something (ditched my iphone for android)
[00:34:03] <PCW> ConnectBot is Android
[00:35:39] <Tom_itx> jdhNC, you like android better why?
[00:35:55] <Tom_itx> like i said.. i don't have either one
[00:36:55] <jdhNC> iphone 3.5", my phone 4.3", I can read it
[00:37:57] <jdhNC> and, I wanted to be able to display/graph some data on the phone (from an AVR) and it is simple on android and doesn't require a mac
[00:42:57] <JT-Shop> mhaberler: ok, thanks for looking at it
[00:44:01] <JT-Shop> and yes a K word would be needed for thread pitch
[00:46:54] <mhaberler> other than that a retract to the R plane I guess
[00:47:22] <mhaberler> g33.1 returns to the starting position
[00:47:41] <JT-Shop> yes, it should be the same as G81 but tapping

[01:00:32] <mhaberler> could you give this a try? http://git.mah.priv.at/gitweb/emc2-dev.git/commit/a6c74c209b218b69ec15d1eaeaaca4004aa2b987
[01:00:40] <skunkKandT> for non rigid tapping...
[01:01:10] <mhaberler> I have a simulator only, not near a machine; g33.1 blocks on sim
[01:01:48] <JT-Shop> it should run on the Axis lathe sim with simulated spindle feedback
[01:02:12] <mhaberler> hm..
[01:04:22] <JT-Shop> I'm on a winblows machine here at the moment
[01:04:42] <mhaberler> I can give it a try tomorrow I guess
[01:05:23] <mhaberler> G84 says 'right hand tapping' - unclear what drives tapping direction; the spindle direction?
[01:05:34] <mhaberler> ah, disregard
[01:05:45] <mhaberler> I thought of left & right hand tapping
[01:05:45] <JT-Shop> be CW in CCW out
[01:06:11] <JT-Shop> I can also try in the morning
[01:06:12] <mhaberler> ok, the obvious thing would be to do g84.1 left hand
[01:06:19] <JT-Shop> yea
[01:06:36] <mhaberler> anybody out there with a left hand tap ;-?
[01:06:47] <JT-Shop> I have several
[01:06:58] <Tom_itx> i've use em but have none currently
[01:07:04] <mhaberler> uh, you are my stunt man;)
[01:07:19] <JT-Shop> quite common for adjustment to have a right hand thread on one side and left on the other
[01:07:58] <mhaberler> ok, lets see if this patch makes any sense, and we go from there; we still need to interview chris why he gave up on it
[01:08:14] <mhaberler> reduce blunder score..
[01:08:19] <JT-Shop> ok, thanks a million for looking at it this late in the evening
[01:08:33] <mhaberler> cut air only..
[01:09:22] <JT-Shop> I can test on the lathe only at the moment until the BP knee mill conversion is complete
[01:09:52] <mhaberler> ok, I'll ty on my mill tomorrow
[01:11:53] <skunkKandT> i could probably test it too...
[01:12:22] <mhaberler> no workpiece nearby..
[01:13:15] <mhaberler> sure, give it a try; I have never worked on cycles so it might execute nonsense
[01:13:38] <rob__H> mhaberler, here is abit from fanuc manual on some codes.. www.innovative-rc.co.uk/fanuc-tapping.pdf
[01:14:08] <mhaberler> thanks, reading
[01:14:11] <rob__H> only thing is G84 is normaly reserved for tapping with floating holder.. as per man
[01:14:17] <rob__H> G74 for left
[01:14:30] <rob__H> g84.1 being rigid cycle
[01:14:47] <mhaberler> aha
[01:15:13] <rob__H> so cradek might say g84 was ment to be a floating cycle ?
[01:16:06] <rob__H> as just program feed rate.. and waits for spindle at speed. then feeds in at feed rate programmed.. gets to Z dether.. reverse feed back out but not truly synced like rigid is
[01:16:16] <mhaberler> no; manual says its undefined, and the code is commented out; I dont think that ever worked because it didnt use the RIGID_TAP canon command
[01:16:18] <rob__H> as spring in holder lets tap follow in and out loose
[01:16:45] <rob__H> hopefully makes some sence
[01:16:58] <rob__H> like 1:15am here lo
[01:17:36] <skunkKandT> rob__H: where are you?
[01:18:23] <rob__H> uk
[01:18:47] <rob__H> windy rainy UK right no
[01:18:50] <rob__H> w
[01:19:20] <JT-Shop> clear and cold in swamp east missouri
[01:19:38] <Tom_itx> it was rather cool this morning for sure
[01:19:55] <skunkKandT> cold.....
[01:19:59] <mhaberler> the only advantage in using a floating holder with a non-synced cw in/ccw out motion would be you dont need a spindle encoder?
[01:20:06] <rob__H> more global warming needed
[01:20:16] <rob__H> correct mhaberler
[01:20:24] <mhaberler> I see
[01:20:24] <Tom_itx> that G74 G84.1 must be mill g cycles
[01:20:33] <rob__H> ye
[01:20:39] <Tom_itx> it's completely different in this lathe manual
[01:20:41] <rob__H> came from the mill manual
[01:20:47] <rob__H> i got lathe one
[01:20:53] <JT-Shop> you just guess the rpm is correct with a floating holder?
[01:21:03] <rob__H> yea waits for spindle at speed sig
[01:21:08] <Tom_itx> G74 lathe is transverse grooving
[01:21:15] <rob__H> and u tell it feedrate to go at'
[01:21:18] <Tom_itx> on this okuma anyway
[01:21:20] <rob__H> so just feeds xxx mm./min
[01:22:03] <rob__H> becasue all main controls have two interps.. mill lathe and just solection the control type on load
[01:25:03] <rob__H> fanuc 21i manual says Front Tapping Cycle
[01:25:03] <rob__H> (G84) / Side Tapping
[01:25:03] <rob__H> Cycle (G88)
[01:27:05] <rob__H> off now, bye all

[03:54:34] <jackc> ive built a couple small emc mills... im working on a project where i need to accurately move one angular axis and thought id see if i could use HAL's stuff for it
[03:55:03] <jackc> ideally id plug in one servo driver, then connect to hal or use the hal python module to basically say "new goal position: 30 degrees"
[03:55:32] <jackc> is this a good idea, or am i barking up the wrong tree?
[03:57:22] <archivist> just set the axis to angular
[03:57:47] <archivist> eg A B or C
[03:58:52] <jackc> thats what i figured - i did a stepconf config, then took out the 2nd two axis, named my axis 'c', and changed it to angular
[03:58:57] <jackc> but there are a bunch of errors when i start up
[03:59:05] <jackc> is there a smarter way to debug the .hal?
[03:59:12] <jackc> (other than starting axis and seeing what it says)
[03:59:19] <jackc> ie, whats the cli interface to it
[04:00:41] <jackc> when i do 'halcmd -f single.hal' (or any of the other hal cmds) i get "RTAPI: ERROR: could not open shared memory"
[04:01:12] <jackc> "RTAPI: Locked memory limit is 64KiB, recommended is at least 20480KiB"

[07:02:39] <automata_> I am trying to reset the feedback position (position-fb) for a hostmot2 stepgen to a given value
[07:02:45] <automata_> not sure how to do that!!
[07:04:38] <automata_> I have a servo motor that is controlled with step and direction pulses...
[07:05:48] <automata_> I want to use it sometimes as a spindle using and sometimes as a position based device
[07:06:12] <automata_> sometimes as the axis C
[07:14:04] <automata_> I guess as soon as I change the control type of the stepgen, the position-fb changes its value to 0

[10:31:43] <EMCUser> hey, I just wondered if there is a Graphical editor for HAL files out there. Something similar to the Shader Editors of 3D-Engines: ( http://warby.bitproll.de/projects/9999_wip/warbys_uber_shader.jpg )
[10:34:54] <EMCUser> The hal components would be the nodes and you would be able to connect them via lines. I think it would provide a faster and more convenient configuration.

[11:06:13] <awallin> that would be a very good thing! could include a picture of the hal network for example configs, tutorials, etc.
[11:06:31] <awallin> there is some work in that direction with electronics-schematics tools (geda and/or eagle)
[11:06:50] <awallin> and I think someone tried plotting tha hal netlist with graphviz
[11:32:53] <EMCUser> hmm nice
[11:33:00] <EMCUser> do you know that someone?

[15:07:04] <pcw_home> Hi automata_
[15:21:20] <pcw_home> sutomata_ For running s step/dir controller spindle, I would set the stepgen in velocity mode and use a normal PID loop around the stepgen

[15:29:07] <automata_> Hi PCW_home
[15:29:20] <automata_> good morning.
[15:30:12] <automata_> Any reason to use a PID loop around the stepgen?
[15:32:01] <pcw_home> there no pure velocity mode without it
[15:32:08] <automata_> I have another problem: I had bought 10 pcs of 7i43P - 2K. I think one of my PC's power supplies fried and took out the U1 IC with it.
[15:32:37] <pcw_home> well actually you could use it open loop
[15:33:04] <automata_> Now with I connect 5V power to the board, I can see the magic smoke (still) coming out of it...
[15:33:42] <automata_> I was hoping to use it open loop... there is no reason to run it closed loop...
[15:34:07] <pcw_home> Smoke is hardly ever a good sign
[15:34:50] <automata_> I also could not catch all the magic smoke... so I can't put it back in... ;-)
[15:35:20] <automata_> anything you can suggest I try?
[15:36:33] -!- syyl [syyl!~syyl@p4FD14686.dip.t-dialin.net] has joined #emc
[15:36:39] <automata_> I am amenable to soldering too ...
[15:37:01] <automata_> I have a hot air solder gun to cleanly lift U1 out...
[15:37:31] <automata_> though I am not sure what I would replace it with...
[15:38:10] <pcw_home> I dont know what U1 is offhand
[15:39:11] <automata_> I am thinking it is a voltage regulator... (placed close to the power input connector)...
[15:40:48] <pcw_home> OK its the serial EEPROM, its not a good sign (means 3.3V that powers most chips on board was WAY too high at some point)
[15:41:22] <automata_> oops...
[15:41:42] <automata_> not an easy replacement then....
[15:41:49] <pcw_home> as far as soldering goes isthe rest of the card survived, it will run without that chip
[15:42:00] <pcw_home> if the rest
[15:42:36] <automata_> In that case, I will lift it out of the board and let you know the results...
[15:43:48] <automata_> Another question for PWM to analog conversion: Do you have a low cost board that can do only PWM to analog conversion?
[15:44:11] <pcw_home> how many channels?
[15:44:14] <automata_> I am trying to operate a Fuji Frenic mini VFD.
[15:44:17] <automata_> 1 channel
[15:44:33] <automata_> ok having 2 channels would be better...
[15:45:28] <pcw_home> No but i keep thinking I should do this so 2 channels +-10 or just 0 to 10 and dir?
[15:45:56] <pcw_home> Ill make one for the next proto panel we do

[19:43:59] <A2Sheds> size and torque
[19:44:14] <IchGucksLive> i use NEMA23
[19:44:20] <IchGucksLive> 1,2Nm
[19:44:30] <IchGucksLive> out of the epson laserjet
[19:44:34] <A2Sheds> that low
[19:44:55] <IchGucksLive> 2,4V 1,8A at 24V 12Euros
[19:45:05] <IchGucksLive> TR12x3
[19:45:18] <IchGucksLive> you can go with Timbelt 1:2
[19:45:21] <A2Sheds> yeah, I've been tempted to a lot of them on ebay
[19:45:43] <IchGucksLive> this gives you then around 6Nm torque at the tool
[19:47:23] <IchGucksLive> A2Sheds: 23LM-C355-44W
[19:47:48] <IchGucksLive> this is what i wuse i got 50 for 100 Euros from a dealer
[19:48:09] <IchGucksLive> 8wire so speed or torque can be pulled
[19:48:21] <A2Sheds> yeah, I saw 100 for $500

[19:57:13] <IchGucksLive> this hits all my pricelimits

[20:04:03] <IchGucksLive> 100
[20:04:24] <IchGucksLive> 1m =100cm
[20:04:34] <archivist> that I agree
[20:04:39] <IchGucksLive> 1cm =0.01m
[20:05:01] <FinboySlick> So 0.01 * 920N/cm
[20:05:04] <IchGucksLive> l1xf1=l2xf2
[20:07:00] <archivist> so the force at a metre is greater than at 1cm you think...time to learn levers

[21:51:16] -!- Adelie has quit [Quit: leaving]
[21:51:22] <jackc> sec, checking
[21:52:00] <jackc> yes - its in basethread. stepgen.capture-position and .update-freq are in servo-thread
[21:52:26] <andypugh> Is position-fb moving?
[21:53:01] <jackc> yes
[21:53:07] <jackc> oh, dir is changing
[21:53:13] <jackc> it must be stepping too fast for halmeter to see
[21:53:30] <jackc> hmmmm
[21:53:42] <andypugh> Yes, it could well be. Use Halscope, in the base thread?
[21:54:12] <jackc> i couldnt get halscope to show me anything, but its prolly user error. lemmy try again
[21:56:35] <jackc> oh hey
[21:56:41] <jackc> it works! thanks for the debug help

[22:01:09] <andypugh> My encoder target works too :-) That saves me £200
[22:01:53] <tom3p> andypugh, that wasnt a coil embedded in some potting material? haha, whats an OHP pen?
[22:02:06] <andypugh> Overhead Projector Pen
[22:02:54] <andypugh> Staedtler Lumograph. It is actually what you get if you buy an etch resist pen from RS or Maplin nowadays. They work better than the dedicated resist pens.
[22:05:39] <tom3p> well i cant find decent vacuums <10amp 120Vac so its time for an intermediate relay after the gordos ssr. ( expensive to run AND noisy as hell )
[22:06:22] <andypugh> tom3p: Use 240V?
[22:07:04] <tom3p> at home in usa, well there is 220 single phase but i ate that up for the edm power supply
[22:09:13] <jdhNC> get a better ssr
[22:10:54] <tom3p> ssrs for rackmount with 120v 12amp? dunno who makes such http://imagebin.org/191809

[22:11:56] <andypugh> Does it have to be rackmount?
[22:12:01] <tom3p> i could use a brick i suppose, they'll go 15 amp
[22:12:05] <tom3p> righto
[22:12:15] <jdhNC> http://www.mpja.com/25A-480VAC-SOLID-STATE-RELAY/productinfo/17155%20RL/
[22:12:50] <tom3p> jdhNC, thx! ( marlin P to the rescue)
[22:13:42] <jdhNC> I have one of those mounted in a single gang box with a duplex outlet. Spindle and vacuum plugged in to it.
[22:14:15] <tom3p> haha same here ssrs running each of the outlets of a duplex
[22:14:21] -!- FinboySlick has quit [Quit: Leaving.]
[22:15:00] <jdhNC> same ssr for mine, vacuum comes on with spindle
[22:15:26] <andypugh> There is a 40A on that site for only a few more $
[22:16:21] <jdhNC> they have some high current DC ones also
[22:16:22] <tom3p> http://imagebin.org/191812
[22:17:31] <tom3p> the 1st ssr runs that festo solenoid for air blast at tool tip
