[02:08:12] <Tom_itx> i was rather surprised how empty the mall was today

[02:23:45] <andypugh> Or even a Flashmob
[02:24:03] <tjb1-mobile> Is it bad to move a stepper manually when the drive isnt under power?
[02:24:16] <jdh> not for the motor
[02:24:23] <Tom_itx> it could be bad on the driver
[02:24:43] <andypugh> Only if you move it rather fast, I supect.
[02:24:56] <tjb1-mobile> Ill have to ask gecko about it
[02:25:17] <andypugh> I do it quite often (as my lathe is still usable manually) and nothing bad has happened yet.
[02:25:32] <jdh> shouldn't hurt a gecko

[02:25:53] <tjb1-mobile> My drive fault light lights up when I move mine
[02:25:57] <Tom_itx> no probably not but all drivers aren't created equal
[02:25:58] <tjb1-mobile> Thats when drive is unpowered
[02:26:28] <andypugh> I have to say that flashmobbing is one one the most fun things that social media have brought us.
[02:26:44] <Tom_itx> yeah
[02:27:24] <andypugh> OK, I am drunk and I am bored, and I have eBay open. What should I look for?
[02:27:29] -!- cmorley1 has quit [Ping timeout: 255 seconds]
[02:27:33] <jdh> uh oh.
[02:27:41] <Tom_itx> anything you don't really need but possibly want
[02:28:00] <Tom_itx> if you searched when sober it wouldn't cross your mind to get it
[02:28:48] <andypugh> Hmm, latex basque
[02:29:05] <andypugh> (not _nearly_ that drunk)
[02:30:12] <tjb1-mobile> Little late for you andypugh ?
[02:30:19] <andypugh> 'appen
[02:32:47] <andypugh> Though my frequent search for "cnc lathe" with condition "for parts or not working" has found something: http://www.ebay.co.uk/itm/cnc-lathe-/230891194210?pt=UK_Home_Garden_PowerTools_SM&hash=item35c2300762
[02:33:48] -!- kmiyashiro has quit [Quit: kmiyashiro]
[02:35:27] <jdh> looks like it needs a lot of space
[02:35:35] <tjb1-mobile> Home and garden hug
[02:35:37] <tjb1-mobile> Huh
[02:35:40] <andypugh> That's why it isn't mine now.
[02:37:10] <andypugh> I wonder if you can make a living fixing up that sort of thing?
[02:37:37] <jdh> any living, or a decent living.
[02:37:40] <Tom_itx> i suppose tool suppliers do
[02:37:41] <tjb1-mobile> Why dont you try
[02:38:14] <andypugh> Well, yes, I make a good living from my job, so that would only be a backup if it went wrong.
[02:38:17] <Tom_itx> or you could lcnc it and make a living making parts
[02:39:12] <Tom_itx> the extras alone may be worth the 2k
[02:41:24] <kwallace> For a long time there has been too little margin in making parts, unless one finds a specialty.
[02:42:07] <jdh> http://www.ebay.com/itm/121033757061
[02:42:21] <jdh> that woudl be fun to play with for a bit. Don't suppose you could actually cut much with it.
[02:48:34] <kwallace> Too bad that EMCO doesn't have the tool changer, although it might be easy to make one. Slap a dumpster PC and LinuxCNC on it and put it back on eBay with a fancy video.
[02:48:54] -!- tjb1-mobile has quit [Ping timeout: 240 seconds]
[02:50:16] <andypugh> That's pretty cheap for a little Emco
[02:50:51] <kwallace> Andy, I had to look that one up, can't seem to get it out of my mind.
[02:50:52] <jdh> there is a tool changer on there for $450
[02:53:12] -!- tjb1 [tjb1!~tjb1@181.sub-174-252-208.myvzw.com] has joined #linuxcnc
[02:55:47] <tjb1> Is there a debounce setting for limits? Mine is blowing by a 1/2" wide target at 400 ipm
[02:56:29] <jdh> you can add one, but there isn't by default.
[02:56:39] <Tom_itx> i added one on mine
[02:57:25] <tjb1> Well I was hoping to turn something down...
[02:57:37] <tjb1> I can see the switch activated but Linuxcnc doesnt always treat it as a limit
[02:57:41] <jdh> does it not see it at all, or just not in time?
[02:59:01] <tjb1> Both
[02:59:21] <tjb1> I havent checked to see if the input is triggering with hal meter
[02:59:27] <tjb1> But I can see the prox sensor light up
[03:00:33] <kwallace> humm, this one is an hour's drive away http://www.ebay.com/itm/300828261507?. I wonder if they'll sell it whole?\
[03:01:03] <andypugh> how far do you travel in 1mS/
[03:02:45] <tjb1> 400 ipm = .16933 meters per second
[03:02:49] <tjb1> Is that what you wanted?
[03:02:56] <jdh> 6.66 thou?
[03:03:14] <tjb1> Oh 1 millisecond, silly metric...
[03:03:51] <tjb1> Yeah what jdh said
[03:04:07] <andypugh> I get 75 servo-threads per 1/2" travel. Either you have a very long debounce, or it simply isn't triggering the hal pin
[03:04:09] <tjb1> Target for prox sensor is .562" wide
[03:04:28] <tjb1> I havent set up any debounce
[03:04:39] <jdh> is it a cheap chinese prox switch?
[03:04:43] <tjb1> Yes
[03:05:13] <andypugh> Wierd thing with my machine. it is set to metric. G0 Z10 moves Z 10mm. Axis display shows a move of 245mm.
[03:05:26] <andypugh> (err, 254).
[03:05:50] <andypugh> It seems that Axis (and only Axis) is reading positions as inches, but displaying in mm.
[03:05:58] <jdh> bad wiring perhaps? (if the led lights, but the pin doesn't)
[03:06:07] <andypugh> I guess I forgot an INI flle setting.
[03:06:15] <tjb1> I think something with the G540…its going back this week because of bad outputs
[03:06:21] <tjb1> The inputs have also been fuzzy lately
[03:06:41] <tjb1> The prox sensors use to light up dimly then get bright when triggered…they arent doing that anymore
[03:07:00] <andypugh> tjb1: Might be your 5V not being 5V. Look for a common-mode failure, and that is more likely to be outside the G540.
[03:07:13] <tjb1> andypugh: Its a sinking signal
[03:07:41] <Aero-Tec> so does anyone know how to disable a limit for a rotary axis?
[03:07:56] <Aero-Tec> do you set limit to 0?
[03:08:21] <jdh> those little emco's seem to be expensive.
[03:08:29] <Aero-Tec> I just hit the limit
[03:09:13] <Aero-Tec> also I am in mid production run, any way to reset the limit while a program is running?
[03:13:48] <andypugh> Ah, you hit the 999 limit?
[03:14:27] <andypugh> I think G10 L2 (or l20, they confuse me) will let you reset the position.
[03:14:52] <andypugh> Or rehoming it from the menu (but you can't do that mid-part)
[03:15:58] <kwallace> jdh: That's why I thought adding LinuxCNC to the EMCO on eBay then reselling it might make sense, at least for someone in Florida.

[03:30:33] <tjb1> Anyone order that pendant for linuxcnc that was on kickstarter?
[03:30:59] <Aero-Tec> so is there a way to shut off the limit?
[03:31:05] <Aero-Tec> disable it?
[03:31:31] <Aero-Tec> I have a rotary axis and need to shut off the limit
[03:31:38] <Tom_itx> yeah
[03:32:02] <Tom_itx> tjb1, i got mine from PMDX
[03:35:45] <Tom_itx> http://www.linuxcnc.org/docs/html/config/ini_homing.html
[03:36:33] <Tom_itx> HOME_IGNORE_LIMITS
[03:53:25] <Aero-Tec> looked into that
[03:53:49] <Aero-Tec> looks like it is for when the home and limit switch are the same switch
[03:54:23] <Aero-Tec> but does not say anything about it not disabling the soft limits
[03:55:24] <tjb1> anyone good with zippos?
[03:59:38] -!- c60 has quit [Quit: Lost terminal]

[04:36:45] <Aero-Tec> Warning
[04:36:47] <Aero-Tec> Using this will allow the machine to go beyond the soft limits while in operation. It is not generally desirable to allow this.
[04:36:57] <Aero-Tec> it looks like that will do the trick
[04:37:07] <Aero-Tec> but does it for all axis
[04:38:13] <Aero-Tec> with a program as powerful as EMC and with all it can do, it is funny that a simple thing like turn off soft limits in a rotary axis is beyond what it can do

[05:08:41] <Aero-Tec> one other way EMC can be set up to disable a axis soft limit is to set the min and max to zero
[05:09:21] <Tom_L> it might be, i can't remember
[05:10:06] <Aero-Tec> there should be no real world reason to set them both to zero for a real working machine, unless your wanting to disable the soft limits
[05:10:15] <Aero-Tec> I tried it
[05:10:41] <Aero-Tec> setting them to zero only keeps them from moving
[05:17:42] <Aero-Tec> well that did not work
[05:17:52] <Aero-Tec> #NO_FORCE_HOMING in [TRAJ]
[05:18:21] <Aero-Tec> it still will not allow a move with min and max for the b axis set to 0
[05:18:41] <Aero-Tec> so what is the max one can set the limit?
[05:18:46] <Tom_itx> remove the #
[05:18:49] <Tom_itx> and set it to 1
[05:19:04] <Aero-Tec> anyone know

[05:19:13] <Aero-Tec> sorry

[14:47:37] <pilla_> I need to program something but I have no clue how to make it interact with LinuxCNC. I'm working in C++
[14:47:43] <archivist> libraary, are you asking the right question
[14:48:09] <archivist> linuxcnc responds to gcode
[14:49:34] <archivist> what are you really trying to do
[14:50:36] <pilla_> I need to make a program that automatically makes a scan of what's on the table. I need the program to command LinuxCNC to move the axis to a certain point, to stop there and send a signal to tell it's received then the camera will send its feed to the program.
[14:50:47] <pilla_> sorta

[14:54:07] <archivist> there are scanning gcode programs too that output points
[14:54:35] <gmouer> sounds like you need to write a g-code program to move the axis around, pause in predetermined places and send a digital output during that pause
[14:55:11] <gmouer> a M command can send that digital output during the pause

[15:15:40] <gmouer> depends what you mean by "grab" linuxcnc can load and execute gcode files
[15:16:18] <gmouer> that image to gcode example given outputs a gcode file which can then be executed
[15:18:33] <pilla_> I realized I asked a dumb question. Nevermind! :)
[15:18:38] <gmouer> your C++ program could command linuxcnc to execute a loaded file via a HAL pin
[15:19:51] <archivist> almost anything is possible, but is it the right thing to do
[15:20:50] <gmouer> "almost anything is possible" I realize that more and more with linuxcnc, quite amazing
[15:21:52] <archivist> but reinventing a wheel is not needed when it already exists, just search a bit
[15:23:10] <gmouer> yes, but finding some of that info can be a trick searching, that site you gave github.com is one that I have not found before

[15:36:22] <Aero-Tec> the problem with a google search some times is not having the right terms to use so the search gets what you want

[16:53:06] <Aero-Tec> I thought G64 would make a smooth transition from move to move
[16:53:31] <Aero-Tec> I am making springs on the mill
[16:53:48] <Aero-Tec> the spindle is not turned on
[16:55:25] <Aero-Tec> it is just a tool holder and I have a 5th axis that I use for making springs, it is a universal 4th axis, portable, just a motor and planetary gear box that I connect wire forms to
[16:56:16] <Aero-Tec> anyway, it is stopping at each move, it is a spring so it should wind the spring in one move not 3 starts and stops
[16:56:53] <Aero-Tec> any help would be nice, the stops eat up time, and I have 4000 of them to make
[16:57:01] <andypugh> Aero-Tec: It should. Even normal path-following should blend rotary moves.

[17:00:28] <Jymmm> JT-Shop: Heh, now you need to make them into un/load timbers =)
[17:00:31] <andypugh> There is some wierdness about how rotary and linear moves coordinate.
[17:00:41] <Aero-Tec> comes to a complete stop before doing the next move
[17:01:08] <andypugh> I have a vague recollection that inverse-time mode works better.
[17:01:19] <archivist> I would make the P larger to try
[17:01:44] <Aero-Tec> what would you suggest?
[17:02:08] <archivist> I dont know as I want exact stop :)
[17:02:32] <andypugh> You could also try a config with the rotary as your Y axis set up as a linear. That should blend the moves for you.
[17:02:43] <Aero-Tec> inverse time is controlled feed based on spindle speed is it not?
[17:02:59] <Aero-Tec> I have no spindle feed or encoder on spindle
[17:03:09] <Aero-Tec> speed
[17:03:41] <andypugh> No, that's feed per rev. Inverse Time is the _other_ mode.
[17:03:52] <skunkworks> if the accelleration is set really low - it will appear like exact stop
[17:04:03] <andypugh> Where you say how long the move will take.

[17:05:15] <andypugh> Plasma slats?
[17:05:30] <archivist> hmm support...but only just :)
[17:06:16] <Aero-Tec> so can someone explain inverse time to me?
[17:06:17] <andypugh> A plasma cutter would be a better tool for the job, but I guess there is a bootstrapping problem there :-)
[17:06:19] <JT-Shop> yea, new ones fitted into the tank
[17:06:28] <Tom_itx> i like the nice yellow stickers
[17:06:45] <JT-Shop> I cut the first ones using the plasma on saw horses :)

[17:09:04] <andypugh> In G93 mode, G1 X10 A20 F2 means that the move should take half a minute. F4 means 15 seconds. (which is why it is "inverse" time).
[17:11:54] <Aero-Tec> so what possible good does that do?
[17:12:02] <Aero-Tec> what use is it?

[17:15:59] <toastyde1th> coordinating axes that are in different units
[17:16:11] <toastyde1th> if you're doing 3+ axis machining with rotary tables, their units are in degrees
[17:16:30] <toastyde1th> so when you have a feed rate of "15," and one axis is in inches and the other is in inches
[17:16:40] <toastyde1th> that's probably not what you wanted
[17:17:09] <toastyde1th> so inverse time takes care of that and you calculate how long the move should take, and does an end-run around the problem of trying to coordinate the axis feeds
[17:20:36] <Aero-Tec> cool
[17:21:17] <Aero-Tec> I just set the speed insanely high and let the machine try to hit it
[17:22:01] <Aero-Tec> I needed the speed high for deg of rotation
[17:22:46] <Aero-Tec> I have noticed that the rotary axis speeds are not at full
[17:22:59] <Aero-Tec> nor is the linear one
[17:23:23] <Aero-Tec> linear can run at 45 but maxes out at 16
[17:23:48] <toastyde1th> 45 what
[17:24:02] <Aero-Tec> and the rotary one I am not sure what speed it is going but now where near max
[17:24:11] <Aero-Tec> IPM
[17:24:45] <toastyde1th> how long is the move
[17:24:56] <Aero-Tec> is that not what the DRO is set at?
[17:24:59] <Aero-Tec> IPM
[17:25:07] <Aero-Tec> 1 inch
[17:25:24] <toastyde1th> a one inch move isn't going to get an axis up to maximum speed
[17:25:52] <toastyde1th> you'll have to make a long ass move because the machine needs to accomodate the accel/decel
[17:25:53] <Aero-Tec> it hits 16 fast and holds
[17:26:10] <toastyde1th> weird
[17:26:16] <Aero-Tec> it could hit higher for sure
[17:27:06] <toastyde1th> you might want to talk to someone who actually knows about emc, because something could be set wrong?
[17:27:40] <Aero-Tec> I was hoping I was talking to a emc guy
[17:27:50] <archivist> it wont hit top speed if the rotary is holding it back
[17:27:51] <toastyde1th> hah, no
[17:28:05] <toastyde1th> i'm just a machinist, not an emc guy

[17:42:16] <Aero-Tec> the mill is stepper
[17:42:36] <Aero-Tec> should have just said stepper
[17:42:37] <archivist> IchGuckLive, he is doing a coordinated rotary with x

[18:06:10] <Aero-Tec> that is a motor connected to a planetary gear, I use it for making springs

[19:09:13] <archivist> he is coil winding where is accuracy and resolution needed
[19:09:37] <IchGuckLive> setp parport.0.reset-time 5000
[19:09:46] <IchGuckLive> there is a zero missing
[19:09:59] <IchGuckLive> that is your main problem
[19:11:24] <Aero-Tec> just wanting to fine tune things
[19:11:25] <IchGuckLive> setp stepgen.0.stepspace 2 FOR all Axis
[19:11:52] <Aero-Tec> the main thing was it stopping 2 times making 3 moves
[19:13:10] <IchGuckLive> setp stepgen.2.dirhold 45000
[19:13:31] <IchGuckLive> yes it will not stop
[19:13:46] <IchGuckLive> setp stepgen.2.dirsetup 20000
[19:14:00] <IchGuckLive> give this to all axis
[19:14:04] <IchGuckLive> in hal
[19:14:29] <IchGuckLive> and dont forget the latency BASE_period in ini to be set to 15000
[19:14:49] <Aero-Tec> the ini is all done to your specs
[19:14:59] <Aero-Tec> thanks for all this help
[19:15:05] <IchGuckLive> zhen you will se your g-code runnning at nice speed no sto p

[19:17:52] <Aero-Tec> as for the lead screw and steps per inch
[19:18:20] <Aero-Tec> I have a planetary on it
[19:18:29] <Aero-Tec> more power but slower
[19:18:37] <Aero-Tec> It is a acme screw right now
[19:18:49] <Aero-Tec> soon to be upgraded to ball
[19:19:15] <IchGuckLive> balls are very cheep in this days
[19:19:23] <Aero-Tec> true
[19:19:41] <Aero-Tec> I started with nothing and a shoe string
[19:19:48] <IchGuckLive> i looked in a shop anounce 5years ago it wars 10times that price
[19:20:32] <Aero-Tec> my money has gone to tooling and supplies

[19:21:18] <Aero-Tec> getting close to where I can now afford to redo the screws and other updates like new electronics
[19:24:53] <Aero-Tec> bought a new lathe and mill so I could use it for redoing the old lathe and mill
[19:25:21] <IchGuckLive> ok im off for today have a nice day
[19:25:21] <Aero-Tec> would hate to rip the old apart and not have anything to use if needed

[20:08:28] <skunkworks> the mesa resolver interface - only interfaces with the 50pin (like 5i20...)
[20:08:46] <skunkworks> (7I49)
[20:08:56] <skunkworks> nothing for the 5i25 yet?
[20:09:02] <skunkworks> maybe I already asked this..
[20:12:06] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[20:15:13] <andypugh> Yes, it's a 50pin board.
[20:15:39] <andypugh> However, it is probably possible to use it with a 5i25, it's mainly a matter of wring.
[20:16:03] <andypugh> I am liking my 7i49.
[20:16:37] <andypugh> 16777216 cpr encoders :-)
[20:19:15] <skunkworks> wow
[20:19:51] <skunkworks> andypugh: and firmware?
[20:20:12] <andypugh> I think that Mesa say that the numbers are only realy good to 16 bits.
[20:20:45] <awallin> how do you get 16 M counts?
[20:20:45] <andypugh> I think you would have to build a custom 5i25 / 7i49 firmware, then flash it to the 5i25.
[20:20:56] <skunkworks> ok - thanks
[20:20:59] <andypugh> The numbers out of the board are 24bits
[20:23:02] <awallin> ? specs say 14bit adc with about 12bit absolute accuracy

[23:03:08] <JT-Shop> they was on the edge of that cold front
[23:03:09] <Nick001-Shop> Still trying to get yesterdays project going. I have a vertical slide that advances and retracts with M codes. There is an end of travel switch that I have connected to a hal pin. How do I convert that true and false signal into something that M 66 can read.

[23:09:48] JT-Shop-2 is now known as JT-Shop
[23:10:05] <JT-Shop> what does the M66 do?
[23:10:32] <micges> read hal input into gcode variable
[23:10:32] <Tom_itx> waits for input
[23:10:48] <Tom_itx> but it doesn't say where it comes from other than input 0..3
[23:10:54] <JT-Shop> I mean in his M1xx code...
[23:12:39] <Nick001-Shop> m66 waits for a signal
[23:12:43] <Tom_itx> how do you define the inputs though?
[23:13:57] <JT-Shop> M1xx stops executing of G code until it is finished so you don't need M66
[23:14:18] <Nick001-Shop> my M105 and M106 code is parport .0.08-out true and false to a selinoid
[23:14:58] <Tom_itx> JT-Shop, how would you define those on a mesa card though?
[23:15:03] <JT-Shop> ok so your doing a M105 then a M66 Px

[23:15:19] <JT-Shop> you just connect them in hal
[23:15:35] <JT-Shop> motion.digital-in-nn <= input pin

[23:15:41] <Tom_itx> oh ok
[23:16:24] <JT-Shop> did you connect the paraport pin in hal?
[23:17:01] <JT-Shop> net slide-input motion.digital-in-00 <= parport.0.pin10-in
[23:17:18] <Nick001-Shop> yes - I can see it switchine as the switch is on and off
[23:17:40] <Nick001-Shop> switching
[23:18:39] <Nick001-Shop> just the net slide or also the motion.digital--
[23:19:48] <JT-Shop> so M105 and M106 work as expected?
[23:20:24] <Nick001-Shop> yes
[23:20:42] <JT-Shop> and you have the net line similar to the one above?
[23:21:21] <Nick001-Shop> not yet - witch lin do I use
[23:21:29] <Nick001-Shop> and would M66 P00 L3 be correct format?
[23:21:49] <JT-Shop> yes, only one 0 for P is needed
[23:21:59] <JT-Shop> net slide-input motion.digital-in-00 <= parport.0.pin10-in
[23:22:24] <JT-Shop> example from the manual M66 P0 L3 (wait for digital input 0 to turn on)
[23:23:31] <Nick001-Shop> thats what I was reading but couldn't fin the net slide info
[23:23:55] <Nick001-Shop> find
[23:23:59] <JT-Shop> an example would help in the manual...
[23:24:11] <JT-Shop> I'll speak to the manual guy in the morning
