[00:01:18] <chopper791> When I generate the code in sheetcam and try loading it I get the error of can not open file <touchoff> which is a subroutine file. I have the file in my NC folder and there is no reference to placing it anywhere else. Stumped on this
[00:03:15] <chopper791> I see no odd things in the gcode either
[00:04:32] <chopper791> http://pastebin.com/nd65YVLW
[00:04:35] <chopper791> Gcode
[00:04:41] <ssi> most likely answer
[00:04:52] <ssi> the post was made by someone who has a touchoff sub in their nc_files dir
[00:04:53] <ssi> and you don't
[00:05:12] <chopper791> its placed in the NC directory though
[00:05:38] <ssi> what is
[00:05:52] <ssi> the touchoff sub?
[00:07:32] <chopper791> http://pastebin.com/aHcjV9mh
[00:07:41] <mhaberler> see manual on SUBROUTINE_PATH
[00:08:29] <chopper791> mhaberler- looked over that and see nothing that would help in this. unless I am looking over something
[00:08:42] <mhaberler> try in mdi:
[00:08:49] <mhaberler> o<touchoff> call
[00:09:03] <chopper791> The original config has it nowhere either
[00:10:14] <chopper791> Same error in MDI
[00:10:57] <chopper791> sub file is named touchoff.ngc
[00:11:10] <chopper791> andis located in NC directory
[00:11:28] <mhaberler> what does SUBROUTINE_PATH say in your config
[00:11:52] <mhaberler> http://www.linuxcnc.org/docs/devel/html/config/ini_config.html#_rs274ngc_section_a_id_sub_rs274ngc_section_a
[00:13:54] <chopper791> SUBROUTINE_PATH = touchoff.ngc
[00:14:05] <mhaberler> well that is a filename, not a path
[00:14:17] <chopper791> doooh
[00:14:22] <mhaberler> a path is a list of _directories_, not filenames
[00:14:35] <ssi> technically a file can be a path too :D
[00:14:40] <ssi> but I don't think it's what he wants in this case
[00:14:44] <mhaberler> not in this case
[00:15:02] <ssi> chopper791: http://www.youtube.com/watch?v=AsRi7iN7yBI
[00:15:04] <Tecan> (AsRi7iN7yBI) "CNC plasma table" by "imcmahon" is "Tech" - Length: 0:00:11
[00:15:13] <ssi> that's how the x looks at 1800ipm, 60i/s/s
[00:15:31] <chopper791> SUBROUTINE_PATH = /home/chop/emc2/nc_files
[00:16:05] <mhaberler> well try, I dont know if thats the dir your file is in, but if so that looks more promising
[00:16:13] <chopper791> lol
[00:17:12] <RootB> Hey linuxCNC, anyone here with PCB experience?
[00:17:28] <chopper791> Looks like a sweet setup ssi
[00:17:34] <chopper791> I did not see it run though
[00:17:35] <ssi> the mechanicals are shit
[00:17:44] <ssi> I need to redo my belt reductions
[00:18:26] <ssi> also a larger reduction might be nice.... 0.005"/step is kinda coarse
[00:18:30] <mhaberler> chopper791: did that work now?
[00:18:34] <chopper791> mhaberler-still dont work
[00:18:36] <ssi> but I don't think I can get smaller pinions, and larger pulleys isn't ideal
[00:18:48] <mhaberler> paste error message here
[00:19:02] <mhaberler> you did restart linuxcnc?
[00:19:10] <chopper791> my toughoff.ngc is in the NC directory
[00:19:13] <chopper791> yes restarted
[00:19:56] <chopper791> all the error say is unable to open file <touchoff>
[00:20:43] <mhaberler> paste line from ini with SUBROUTINE_PATH here, and then output of 'ls -l '<the directory given>'/t*
[00:21:15] <chopper791> works now........ I forgot to change it from emc2 to linuxcnc
[00:21:20] <mhaberler> aha
[00:21:31] <chopper791> Yeah I feel stupid now
[00:21:41] <ssi> easy mistake to make
[00:21:48] <mhaberler> you hit the right directory, it's a whole new experience ;)
[00:21:57] <chopper791> Thanks,now its time to see if the config works right
[00:21:58] <mhaberler> ok, cu
[00:24:24] <ssi> I want to get my plasma table back running, and then use it to build a better table :P
[00:25:32] <pcw_home> nite all
[00:27:00] <chopper791> good night
[00:27:59] <RootB> why the hell isn't PCBGCode working with eagle on windows 7?
[00:28:05] <chopper791> Well the config works but still no control over z axis
[00:28:23] <chopper791> so I guess it part way works
[00:29:09] <ssi> do you have a machine torch?
[00:29:44] <chopper791> yes
[00:29:51] <ssi> that's one thing I'd like to have
[00:31:15] <chopper791> SO if I look at hal scope the the z pos does not move when I am feeding it up and down commands
[00:31:19] <chopper791> hmmm
[00:32:38] <ssi> well i'm gonna do myself a favor and go to bed earlier than 3am :)
[00:32:40] <ssi> gnight
[00:33:56] <chopper791> good night
[01:23:02] <Loetmichel> mornin
[01:36:50] <Valen> what unit is latency test measured in?
[01:37:19] <archivist> ns iirc
[01:39:12] <Valen> yes
[02:00:27] <chopper791> Anybody on?
[02:01:58] <Gamma-x> me
[02:04:12] <archivist> in irc ask the real questions
[02:05:05] <chopper791> Need some help with an input signal. I need to invert the my parport.1.pin-10-in as its seeing the signal reversed for some reason.I have tried using an invert but startup errors out and says parport.1.10-in is not found
[02:05:11] <Gamma-x> anyone know the correct terminology for the tormach draw bar pneumatic cylinders?
[02:05:34] <chopper791> Sorry I figured I would see if anybody was on before I started typing.
[02:05:40] <Gamma-x> chopper791, what is pin 10?
[02:06:32] <chopper791> pin 10 is my arc ok input pin. The thc moves my z axis when the arc is ok and keep does not move it when the arc is not ok
[02:07:06] <Gamma-x> arc? keep?
[02:07:12] <Gamma-x> dunno those terms
[02:07:20] <chopper791> I have used a -not on the pin and it shows the same results so I figure I would have to invert the signal like a spindle
[02:07:27] <chopper791> arc = plasma arc ok
[02:08:08] <chopper791> keep was not supposed to be there
[02:08:27] <Gamma-x> ohhh
[02:09:36] <chopper791> The issue is if I use a parport.1.pin10-in-invert 1 I receive an error on start up saying parport.1.pin10-in is not found
[02:09:58] <Gamma-x> is it grounded?
[02:10:09] <archivist> use the right name
[02:10:24] <chopper791> what name is that archivist
[02:10:37] <archivist> or create it by using an invert comp (not)
[02:11:21] <chopper791> Not following you on that. Please explain
[02:12:00] <chopper791> setp parport.1.pin-10-in-invert 1 should this invert the signal?
[02:14:59] <Valen> you should just mix negative logic into your code
[02:15:06] <Valen> just to keep you on your toes later on
[02:16:44] <chopper791> Please forgive me but Im kinda new to this
[02:17:07] <Valen> chopper791, don't do what I said, I was being sarcastic ;->
[02:17:19] <chopper791> fair enough
[02:17:36] <chopper791> ;-)
[02:18:18] <chopper791> Am I even able to invert this input signal?
[02:19:08] <archivist> yes
[02:19:34] <chopper791> Does it seem like this is what I need to do before I go at it?
[02:19:35] <archivist> the key word is not which is an inversion
[02:23:53] <chopper791> SO if I was to invert this signal and using setp parport.1.pin-10-in-invert 1 does not do it then how would you suggest go about doing this task?
[02:25:29] <archivist> http://linuxcnc.org/docs/html/hal/components.html#_logic_and_bitwise_components_a_id_sec_realtime_components_logic_a
[02:26:26] <archivist> or you look at the component pins and choose the right name if it has one
[02:27:10] <chopper791> net thc-arc-ok thcud.arc-ok <= motion.digital-in-00 <= parport.1.pin-10-in-not
[02:27:27] <chopper791> using a not or not using a not does not work. Is this what you mean?
[02:28:44] <chopper791> I know that pin 10 is there as my thc uses it fine. Its the logic I guess I would say is reversed.
[02:30:03] <chopper791> When ARC is OK the THC does not move the Z axis, when ARC is not OK the thc will move the z axis
[02:30:23] <archivist> if that is what you want
[02:30:53] <chopper791> sorry when ARC is ok the thc will move the z axis and when the ARC is not OK the thc will not move the z axis
[02:31:21] <RootB> ok linuxCNC
[02:31:24] <chopper791> this should be reversed
[02:31:30] <RootB> im having plenty of trouble with PCBG-Code
[02:33:44] <archivist> chopper79, parport.1.pin-10-in-not is the inverse of parport.1.pin-10-in it is why I have been pointing you at the NOT keyword
[02:34:37] <chopper791> This does not work though
[02:34:45] <chopper791> This was the first thing I tried
[02:35:02] <chopper791> Next was using an invert
[02:35:25] <archivist> not IS and inversion how many times do I have to say that
[02:36:14] <chopper791> Well just once as have used NOT many times before and this time it does not work for me.
[02:36:57] <chopper791> Like I said using a NOT was the first thing I tried and had no results
[02:37:44] <archivist> "does not work" is not a proper statement of a problem, people need a better explanation of the fault
[02:38:20] <chopper791> so how should I explain it then?
[02:42:58] <chopper791> regardless, if I use a NOT or leave NOT out the signal still never inverts.
[02:43:11] <archivist> you could pastebin your hal and ini files, or you could do some diagnosis as to why things are not happening as you expect
[02:43:43] <archivist> not does invert prove it
[02:44:11] <archivist> use halscope
[02:44:33] <archivist> and a real scope on the wire
[02:45:03] <archivist> this is the diagnosis part
[02:46:21] <archivist> do you have a pull up resister to make sure the signal goes high
[02:46:38] <chopper791> I am not denying that the signal does not invert as halscope shows that. The issue is regardless if I use NOT or leave it out, the function of the THC remains the same. I have been diagnosing this issue and now I am seeking help as to why the issue remains after trying multiple different approaches.
[02:47:20] <chopper791> I thought about a pull up resistor but wanted to try without one first.
[02:48:33] <chopper791> I figured that if the signal is working, but just in reverse that I should be bale to do a simple invert and correct it. I guess I am wrong on this.
[02:49:10] <chopper791> The pull resistor up does make sense though so I will give it a shot
[02:50:03] <RootB> Hey linuxCNC
[02:50:08] <RootB> Could you help me out with milling my first PCB?
[02:50:12] <RootB> I can't seem to be able to.
[02:50:41] <archivist> RootB, we are not seeing questions we can answer yet
[02:52:20] <RootB> I really don't have an idea how to set up the coordinates, depth gap and all that
[02:52:51] <archivist> experiment and learn
[02:53:16] <archivist> and it is tooling related too
[03:10:30] <RootB> I'm using V-shaped endbits
[03:10:37] <RootB> But i can't seem to get the depthness right.
[03:10:40] <RootB> If i put too much
[03:10:44] <RootB> It pierces thru the cooper
[03:10:53] <RootB> if i put it just touching the copper, it doesnt even scratch!
[03:13:09] <Gamma-x> with a stepper that is rated for 5 amps.... which of these numbers would you use? Ref Current (Screen printing)
[03:13:10] <Gamma-x>
[03:13:10] <Gamma-x> Peak Current
[03:17:00] <ReadError> RootB
[03:17:20] <ReadError> what i do is, use a DMM with with an alligator clip
[03:17:24] <ReadError> clip 1 to the endmill
[03:17:29] <ReadError> put the other lead on the copper
[03:17:38] <ReadError> then go down in 0.001 increments
[03:17:50] <ReadError> until i get continuity, set that as Z=0
[03:21:07] <RootB> A digital multimeter
[03:21:10] <RootB> ?
[03:21:37] <RootB> ReadError
[03:21:44] <RootB> The problem is, i don't know how to make the g-code properly
[03:21:48] <RootB> I have no god damn idea
[03:21:52] <RootB> what's going on with all the things
[03:25:20] <ReadError> you using eagle?
[03:25:35] <RootB> yes
[03:25:42] <ReadError> using the pcb-gcode thing?
[03:25:54] <chopper791> Well, after a 24hr straight run on this config its time for bed. archivist, thanks for the help. I will give a pull up a try tomorrow.
[03:26:02] <chopper791> good night all
[03:26:06] <RootB> The PCB-GCode thing doesn't work on my eagle god knows why.
[03:26:10] <RootB> GN
[03:27:34] <RootB> im using eagle 5.0.0
[03:29:21] <archivist> doesn't work is not a helpful statement
[03:29:35] <RootB> well
[03:29:37] <RootB> i get a weird error
[03:29:38] <RootB> that says
[03:30:52] <RootB> Unable to open the include file 'source/drill_sizes.h'
[03:31:15] <archivist> so diagnose that error
[03:31:49] <RootB> mmm
[03:31:51] <RootB> well i have no idea man.
[03:31:59] <RootB> I tried everything and it doesnt work
[03:32:12] <RootB> i copied the files, reinstalled it, etc.
[03:32:13] <RootB> nothing
[03:32:47] <Valen> does a file called source/drilletc exist?
[03:32:59] <RootB> Yes
[03:33:43] <ReadError> oh yea
[03:33:46] <ReadError> i think i got that error
[03:33:49] <ReadError> or something similar
[03:33:52] <RootB> really?
[03:33:53] <ReadError> theres some work around...
[03:33:54] <RootB> how did you fixed it
[03:33:56] <ReadError> did you google it?
[03:33:58] <ReadError> no idea tbh
[03:33:59] <RootB> yes
[03:34:00] <RootB> nothing
[03:34:12] <ReadError> sounds like a path issue
[03:34:20] <ReadError> can you search for the missing file?
[03:35:01] <archivist> or permissions
[03:38:04] <RootB> Ok
[03:38:07] <RootB> It just opened, but...
[03:38:20] <RootB> there's no flavour of g-code for me to use
[03:38:24] <RootB> no profiles
[03:39:03] <archivist> and what does that programs manual tell you to do
[03:39:15] <RootB> mmm nothing.. there's no manual
[03:45:11] <ReadError> RootB: theres a tab to select the output type
[03:45:18] <ReadError> 3rd tab or something when you run the setup
[03:45:40] <RootB> I'm getting nothing on my setup, readerror.
[03:45:42] <RootB> just a blank white box
[03:45:47] <RootB> and the rest of the babble
[03:46:03] <ReadError> did you type 'run pcb-gcode-setup' ?
[03:47:06] <RootB> yes
[03:47:15] <RootB> i have nothing
[03:47:18] <RootB> on the gcode style thing
[03:47:29] <RootB> file author description and a blank box
[03:54:38] <RootB> anyone?
[03:56:14] <ReadError> screenshots would help
[03:57:25] <RootB> http://imageshack.us/photo/my-images/94/captureahm.png/
[04:01:01] <RootB> so?
[04:01:41] <ReadError> looks like a path issue
[04:02:07] <RootB> any idea how to solve it?
[04:06:58] <RootB> now im getting can't open 'C:/settings/pcb-defaults.h'
[04:07:00] <RootB> what the fuck
[04:08:56] <RootB> There
[04:08:57] <RootB> Working
[04:13:21] <RootB> wait it's not working properly
[04:13:25] <RootB> what the hell is up with this damn software
[04:13:26] <RootB> jesus fuck
[04:23:42] <ReadError> did you move the files into your eagle directory?
[04:23:48] <ReadError> then load it at the main menu
[04:25:24] <RootB> yep
[04:25:28] <RootB> to ULP
[04:25:34] <RootB> and then i loaded it at the main program
[04:25:45] <RootB> im even thinking on placing the entire thing on the ULC
[04:27:15] <RootB> This is really confusing
[04:27:19] <RootB> No matter what i try, it doesnt work.
[04:35:32] <RootB> anyone?
[04:37:37] <Valen> you may be better off finding an eagle room
[04:37:54] <RootB> this is CNC
[04:37:59] <RootB> and you guys probably mill PCBs
[04:38:01] <Valen> no, its CAM
[04:38:05] <Valen> and its a problem with eagle
[04:38:20] <Valen> if you are having a problem running linuxCnC this is the place to come
[04:38:28] <RootB> oh well
[04:38:38] <Valen> I'm not trying to be harsh
[04:38:54] <Valen> I'm just saying that the problems you are having may be better addressed there
[04:39:03] <archivist> your problems are windows and path based, not something we use a lot in here
[04:43:08] <DJ9DJ> moin
[05:31:07] <carper64_lb> morning gents
[08:36:39] <gabewillen> Can only realtime modules use rtapi_mutex_get?
[08:38:22] <cradek> man rtapi_mutex
[08:43:04] <gabewillen> wow slap in my face
[08:43:08] <gabewillen> lol
[08:43:10] <gabewillen> should of known better
[08:43:31] <gabewillen> i man, rtapi, and hal, but not that
[08:43:35] <cradek> it's not a slap, it's a clear and concise pointer to the information you need :-)
[08:43:36] <gabewillen> thank you
[08:43:41] <cradek> anytime
[08:43:53] <gabewillen> no not by you, just i feel like an idiot, its clear as day written in there
[08:44:13] <cradek> probably rtapi_mutex_get should be a symlink to rtapi_mutex, but it isn't
[08:44:31] <cradek> because it took me two tries to find the manpage
[08:44:38] <cradek> bbl
[08:46:06] <gabewillen> the reason i ask is that i have wrapped liblinuxcnchal using python ctypes
[08:46:22] <gabewillen> im working on a halgui, but im writing a python version of halcmd
[08:46:48] <gabewillen> i can use every function thus far, and objdump shows rtapi_mutex but i can't access it from that library
[08:46:52] <cradek> hm, are you sure that wasn't already done?
[08:47:26] <gabewillen> well there is _hal.so, but its not wrapping every part of hal
[08:47:44] <cradek> ah, maybe that's what I was thinking of
[08:48:01] <gabewillen> its works great for what gvcp requires
[08:48:14] <gabewillen> but using ctypes is a better approach as far as keeping up with changes
[08:48:33] <gabewillen> much easier than rewriting c code if hal_lib where to change
[08:50:10] <gabewillen> i have almost all the functions working, but, i can load modules, it checks if your using a pre-compiled version of linuxcnc or a devel version. rips the environment for you if your using a dev version
[08:51:26] <gabewillen> i can get the base hal_data struct. But im basing this mostly off of halcmd, and i can't seem to access the rtapi_mutex calls
[09:02:06] <skunkworks> lok andy
[09:02:09] <skunkworks> *lol
[09:11:55] <archivist> hehe I just read it
[09:18:55] <skunkworks> sad but true though...

[09:31:33] <skunkworks> ssi, get it figured out?
[09:31:38] <ssi> skunkworks: yea more or less
[09:31:45] <ssi> I got X/Y jogging at least
[09:31:52] <skunkworks> what was the issue?
[09:31:56] <ssi> not sure
[09:32:01] <ssi> I just started over with the hm2-stepper config

[09:32:14] <ssi> 1800ipm :P
[09:33:19] <JT-Shop> be seeing some sparks soon from the revived plasma table
[09:33:25] <ssi> I sure hope so
[09:33:35] <ssi> I kinda want to rebuild the belt drives
[09:33:36] <r00t4rd3d> skunkworks, cnc this
[09:33:37] <r00t4rd3d> http://watertown.craigslist.org/tls/3744568791.html
[09:33:40] <ssi> belt reductions rather
[09:33:42] <ssi> they sorta suck
[09:34:24] <ssi> for whatever reason, I didn't slot the motor holes, so there's an idler in a slot for belt tension
[09:34:27] <ssi> and it doesn't hold
[09:34:35] <ssi> I need to go back and slot the motor holes and order shorter belts
[09:35:13] <skunkworks> well.. We are planing on cnc'ing this.. http://www.youtube.com/watch?v=2fUcCoj7APQ

[09:37:02] <jdh> in my experience, anything that is slotted will end up being mounted at one end of the slot.

[09:38:13] * skunkworks counts to 10.. No issue yet...
[09:38:34] <ssi> jdh: yeah that's about the size of it
[09:45:11] <L84Supper> http://www.youtube.com/watch?v=zedsBIXKaZI I come across these old turret lathes all the time, for the price of scrap or free if you can just get it out of here

[09:49:57] <ssi> that's a cool machine
[09:50:12] <L84Supper> Chicago, Milwaukee, Madison area
[09:50:27] <ssi> wonder how hard it is to get tooling for them
[09:50:35] <ssi> those toolholders don't look real common
[09:50:39] <skunkworks> L84Supper, where are you?

[09:53:44] <ssi> heh nice
[09:53:53] <ssi> tbh the last thing I need is another lathe
[09:54:03] <ssi> I have three lathes, two of them are cnc and only 1 manual mill :(
[09:54:05] <archivist> very badly place levers on that beast
[09:54:48] <L84Supper> Warner & Swasey Company was in Cleveland, probably explains why there are so many of them still around here
[09:57:11] <jdh> http://www.bidspotter.com/forms/staticitem.php?photo=16194087&gallery=21046
[09:57:18] <jdh> how would one transport that?
[09:57:35] <L84Supper> archivist: did you see they guy reaching between the levers in the video?
[09:58:06] <archivist> L84Supper, yes terrible lever placement
[09:58:25] <archivist> about the worst I have seen on any machine
[09:59:05] <L84Supper> jdh: take the cabinets off and it will fit into a pickup
[10:00:09] <L84Supper> I came across one 2 years ago that still had accessories in the original factory wax paper bags from the 50's
[10:01:01] <ssi> jdh: I moved my clausing 12x36 on a tilt-bed rental trailer
[10:01:15] <jdh> ssi: how did you get it off the trailer?
[10:01:19] <archivist> L84Supper, and did you see where his head was when adjusting the cross travel lever
[10:01:50] <ssi> jdh: it has a pair of wood skids bolted lengthwise to the bottom of the cabinets
[10:01:56] <ssi> and we put it on pipes and rolled it
[10:02:51] <Loetmichel> the good old (ancien) egyptian way?
[10:02:56] <Loetmichel> +t
[10:03:01] <ssi> yep
[10:03:05] <ssi> I've moved a lot of machines like that
[10:03:12] <ssi> it sucks, but it works :)
[10:03:20] <ssi> I moved my 9x42 mill that way
[10:03:27] <ssi> but I had to take the table off it and flip the head over to get it through a door
[10:03:30] <ssi> hahah
[10:11:11] <L84Supper> archivist: would you rather be an operator of that lathe or have to couple these cars https://www.youtube.com/watch?v=Yv_FXesGVzU
[10:21:54] <Gamma-x> anyone have a tormach unit?
[10:22:28] <Gamma-x> im interested in getting specs on the belleville washers they use on there power drawbar kit.
[10:26:33] <Aero-Tec> I need to change owner of a file
[10:26:42] <Aero-Tec> I tried su user
[10:26:52] <Aero-Tec> that did not work
[10:27:27] <Aero-Tec> the owner is root, my ID is in the root group
[10:28:13] <ssi> who was it that has the plasma table with the cncrouterparts rack and pinion stuff
[10:28:16] <ssi> ReadError?
[10:29:07] <Aero-Tec> do you have to use sudo with some command?
[10:29:12] <pcw_home> sudo chown user filename or
[10:29:14] <pcw_home> sudo chown user:group filename
[10:29:25] <ssi> sudo make me a sandwich
[10:29:32] <Aero-Tec> lol
[10:29:38] <ssi> http://imgs.xkcd.com/comics/sandwich.png
[10:30:02] <Aero-Tec> wish it would, I could use one right about now
[10:31:07] <Aero-Tec> you would have to be in the dir or use the full path to the file for that to work, right?
[10:31:13] <ssi> yes
[10:57:22] <Aero-Tec> wow thanks for the help, that little sudo and change owner sure has help me fix a ton of problems
[10:58:36] <Aero-Tec> when I make a file using my windows box the owner is nobody, funny thing is owner nobody trumps the admin and root group user
[10:59:26] <Aero-Tec> any way to set owner nobody so admin user can edit the file?
[11:00:29] <Aero-Tec> also I see there are at least 2 way to name a variable, not sure what will work with the latest version
[11:01:02] <Aero-Tec> what is the simplest and quick way to declare a variable and name it
[11:02:05] <Aero-Tec> like dia for setting the stock size on a lathe
[11:07:40] <r00t4rd3d> lets say i order 2 separate orders from the same company, i get charged shipping for both orders but they ship them in the same box. Should I get my shipping cost back for 1 order?
[11:09:15] <Aero-Tec> possibly part of it, would depend on size of box and weight
[11:09:40] <r00t4rd3d> flat rate box so size or weight made no difference
[11:11:06] <Aero-Tec> if the 2 small shipping orders size and weight when added together equal what the shipping would be on a larger and heavier box then probably not
[11:11:18] <Aero-Tec> ok then for sure yae
[11:11:26] <Aero-Tec> ask for a refund
[11:11:43] <Aero-Tec> I wish we had that here in canada
[11:11:55] <Aero-Tec> shipping up here is nuts
[11:12:59] <Aero-Tec> up here Canada post in a private company
[11:13:10] <Aero-Tec> and they like to rip us off
[11:14:12] <Aero-Tec> the gal at the desk says bend over when it time to pay the bill, and lube is extra
[11:14:14] <Aero-Tec> lol
[11:18:50] <jdh> USPS is also a private company
[11:25:26] <Aero-Tec> my browser froze for a bit
[11:25:38] <Aero-Tec> did I miss anything?
[11:25:47] <archivist> no
[11:25:54] <Aero-Tec> got that usps is also private
[11:26:00] <Aero-Tec> cool
[11:26:05] <archivist> use a real irc client
[11:26:11] <jdh> we were waiting for you.
[11:26:17] <Aero-Tec> lol
[11:26:24] <Aero-Tec> thanks guys
[11:26:34] <Aero-Tec> what a great bunch of guys
[11:26:36] <Aero-Tec> lol
[11:26:58] * archivist likes being waited on, and demands cake
[11:27:07] <Aero-Tec> what IRC client should I use?
[11:27:22] <archivist> I use xchat
[11:27:27] <jdh> I like ircII-Epic, but I've been using it for 15 years
[11:28:47] <Aero-Tec> looks like I may have mIRC
[11:28:55] <Aero-Tec> not sure how good it is
[11:29:12] <jdh> it's ok, if you like windows.
[11:30:18] <cradek> > It is an easy way to sink a fair bit of money into a pile of junk to end up with a computer-controlled pile of junk.
[11:33:04] <Aero-Tec> so what windows IRC client should I be getting, free ones would be good
[11:34:33] <jdh> I like my computer-controlled piles of junk.
[11:34:41] <Connor> cradek: What is ?
[11:34:57] <Aero-Tec> guess I should search source forge
[11:35:07] <jdh> or google
[11:35:55] <GammaX> what type of steel is tool holders for lathes usually made out of?
[11:36:31] <jdh> I need to go to the post office and mail some junky dive gear that I would never use to some guy that will be quite happy to have it.
[11:36:41] <GammaX> example http://www.ebay.com/itm/3-position-Gang-tool-Haas-Cubic-OmniTurn-SNK-/280422199561?pt=LH_DefaultDomain_0&hash=item414a773109
[11:38:19] <Aero-Tec> what is the best way to name a variable in Gcode for linuxCNC?
[11:43:15] <JT-Shop> what ever makes sense to you...
[11:45:51] <Aero-Tec> I had seen the docs about it before, but now that I need the info I can not find the docs
[11:46:00] <Aero-Tec> frustrating
[11:46:19] <syyl> a good variable should have a name that gives it some personality
[11:46:26] <syyl> like "hugo" or "fritz"
[11:51:42] <Aero-Tec> lol
[11:52:20] <Aero-Tec> I was asking about the best way to declare a named variable
[11:54:14] <Aero-Tec> the syntax
[11:54:45] <JT-Shop> crap just scrapped a part
[11:58:28] <Aero-Tec> not good
[11:59:36] <IchGuckLive> HI all B)
[12:01:08] <IchGuckLive> tomorrow dads day milling not allowed O.O
[12:01:29] <IchGuckLive> only Beer and BBq
[12:01:42] <IchGuckLive> best day ever !
[12:28:38] <Loetmichel> re @ home
[12:58:56] <generic_nick|2> i hate it when that happens JT-Shop
[13:00:09] <generic_nick|2> well, my cherry picker can lift the stripped down base of my mill. time to go borrow the trailer and load it up.
[13:00:27] <generic_nick|2> sketchy as hell, but hopefully it'll work.
[13:01:19] <generic_nick|2> gotta imagine it's 3000lbs
[13:01:50] <generic_nick|2> the ram has to be another 1000 or so
[13:02:48] <IchGuckLive> US police doesent mind if ypou overload
[13:03:08] <IchGuckLive> see mythbusters on germen VW Jetta
[13:03:32] <generic_nick|2> i wont be overloaded on the trailer. it's a 10,000gvwr
[13:03:37] <IchGuckLive> 800lbs on load paper and 3000lbs taken
[13:03:51] <generic_nick|2> completely legal.
[13:04:09] <IchGuckLive> so call your friends and make a BBq

[13:49:52] <ssi> hm so what next
[13:58:42] <andypugh> I wonder what that Aciera on eBay I posted to the mailing list will go for? The last one I saw (with a _full_ set of accessories, on the stand, with the wooden cases) went for $16k.
[14:00:24] <archivist> are you taking out a mortgage :)
[14:05:46] <Schmelzer> Hallo Zusammen
[14:07:39] <Schmelzer> Jemand online dem sich mir vll ein wenig helfen kann???
[14:08:06] <Loetmichel> Schmelzer: dont ask to ask, just ask!
[14:08:17] <Loetmichel> oder auf deutsch: raus damit ;-)
[14:08:28] <Daywalker198454> puh doch deutsch ... ;)
[14:08:29] <cradek> Daywalker198454: can you use English?
[14:08:39] <Loetmichel> oh
[14:08:45] <Loetmichel> sorry, here is english ;-)
[14:08:48] <Daywalker198454> not perfect
[14:08:49] <Loetmichel> right
[14:09:07] <ssi> any idea how I can tell the pressure angle of a rack/pinion set?
[14:09:07] <cradek> fortunately none of us is perfect either
[14:09:14] <ssi> they've fallen out of my mcmaster history :/
[14:09:17] <Daywalker198454> ok ill try
[14:09:30] <andypugh> SSI With a protractor.
[14:09:42] <Daywalker198454> i am new on linux cnc
[14:10:05] <andypugh> ssi: In the case of a rack the pressure angle is the tooth angle. It is that simple.
[14:10:17] <Daywalker198454> i used mach3 before and thge start with linux cnc is hard...
[14:10:24] <ssi> andypugh: hm I may be able to take a picture of the rack and measure it on the computer
[14:11:27] <Daywalker198454> i have problems setting up the ini and hal for the folowing system
[14:12:16] <Daywalker198454> mitsubishi MRj2 S Step / Dir Servo´s in combination with linear scales
[14:12:46] <andypugh> Did that work with Mach?
[14:13:15] <Daywalker198454> everything is was ok...
[14:14:31] <Daywalker198454> but i want to feed the tableposition back to linuxcnc
[14:14:53] <Daywalker198454> and i dont know hoe to do
[14:15:01] <Daywalker198454> sorry how
[14:15:03] <Daywalker198454> :P
[14:16:07] <ssi> how are your scales connected to your computer?
[14:17:41] <Daywalker198454> for testing on the 2nd parport..., if everything is fine ill buy a mesa 5i20
[14:18:09] <Daywalker198454> an connect everything to the mesa
[14:18:35] <ssi> when you run linuxcnc, can you open Hal Configuration window, add the parport pins to the watch list, and see the signals changing when you move the axis?
[14:19:48] <Daywalker198454> yes... the signals come in...
[14:20:17] <ssi> look at the man page for encoder
[14:20:48] <Daywalker198454> ???
[14:20:49] <ssi> create an encoder component, add it to the servo-thread, connect signals to it, and it will output a position
[14:21:05] <ssi> connect that positiot signal to the pos-fb pin on the axis
[14:21:28] <ssi> (and actually I think that needs to be on base-thread, not servo-thread)
[14:21:32] <Daywalker198454> i am a stepconf using noob ... ;) how to connect
[14:21:34] <ssi> http://linuxcnc.org/docs/html/man/man9/encoder.9.html
[14:21:41] <ssi> you're going to have to read a bit about hal
[14:22:25] <Daywalker198454> done so many times but dont understand it right now....
[14:22:45] <Daywalker198454> what to do first.. and so on...
[14:23:02] <ssi> first, open up your hal file
[14:23:26] <Daywalker198454> ok
[14:23:28] <ssi> at the top, you should have components being loaded, like "loadrt parport" and such
[14:23:39] <Daywalker198454> ok
[14:23:58] <ssi> so you're going to load the encoder component
[14:24:04] <ssi> with the number of encoder channels you need
[14:24:10] <ssi> loadrt encoder num_chan=3
[14:24:20] <Daywalker198454> ahhh ok...
[14:24:22] <ssi> refer to the page I linked above or the man page (man encoder)
[14:24:35] <ssi> that'll create you three encoders, encoder.0, encoder.1, encoder.2
[14:25:26] <ssi> then, according to the man page, there's two functions that need to be added to threads
[14:25:39] <ssi> since you're doing software stepping, you should have a base-thread and a servo-thread
[14:25:56] <Daywalker198454> ok..
[14:26:06] <ssi> addf encoder.update-counters base-thread
[14:26:10] <ssi> that one needs to happen frequently
[14:26:20] <ssi> addf encoder.capture-position servo-thread
[14:26:26] <ssi> man page says that needs to happen less frequently
[14:26:31] <ssi> so I'm assuming that means servo thread is fine
[14:26:43] <Daywalker198454> ok
[14:26:44] <ssi> the addfs will attach those functions to the corresponding threads
[14:26:55] <ssi> which means they'll get called when those threads run
[14:27:06] <Daywalker198454> k
[14:27:15] <ssi> then you need to connect your signals
[14:27:20] <ssi> is it an indexed encoder?
[14:27:29] <ssi> A/B/Z? or just A/B?
[14:27:39] <ssi> I'm assuming it's quadrature
[14:27:43] <Daywalker198454> yes it has indexsignal
[14:27:47] <Daywalker198454> yes
[14:27:48] <cradek> what position feedback goes to your step-servo drives?
[14:27:50] <Daywalker198454> ttl
[14:28:15] <Daywalker198454> ecoder on motorshaft
[14:28:25] <Daywalker198454> ac servo´s 750W
[14:28:30] <ssi> so you have rotary encoders on the motors, and linear encoders on the axes
[14:28:31] <ssi> weird
[14:28:46] <cradek> ah ok. very unusual setup.
[14:29:10] <ssi> so now wire the parport pins to the encoder
[14:29:12] <cradek> maybe you will want to run the step-servos stepgens in velocity mode
[14:29:17] <ssi> you know the hal names of the pins?
[14:29:29] <ssi> it'll be something like:
[14:30:06] <ssi> net x-enc-a encoder.0.phase-A <= parport.0.in-01
[14:30:15] <ssi> (x-enc-a is the signal name, and I completely made it up)
[14:30:22] <ssi> you need to attach A, B, and Z for each encoder
[14:31:05] <ssi> and you'll also need to setp encoder.0.position-scale XXX
[14:31:08] <Daywalker198454> ok.. the <= is for input and => for output?
[14:31:10] <ssi> whathever the scale of the encoder is
[14:31:23] <ssi> <= and => don't mean anything, hal ignores them
[14:31:32] <ssi> they're there to keep straight what's what, for your own menefit
[14:31:34] <ssi> benefit
[14:31:58] <ssi> but yeah, I used it there to indicate the signal from parport goes into the encoder phaseA pin
[14:32:17] <Daywalker198454> can i write "net x-enc-a encoder.0.phase-A parport.0.in-01" too??
[14:32:30] <ssi> yep
[14:32:43] <ssi> whatever makes it clear in your mind :)
[14:32:51] <Daywalker198454> ok.. i´ll try
[14:33:16] <ssi> the position-scale needs to be set to the counts per unit
[14:33:16] <Daywalker198454> it is hard to understand when nobody helps you understand it-... :P
[14:33:24] <ssi> it's a tall mountain to climb
[14:33:27] <ssi> but we all had to do it :)
[14:33:53] <Daywalker198454> mach3 was really simple
[14:34:01] <ssi> it's TOO simple
[14:34:23] <Daywalker198454> but you can´t close the loop in realtime
[14:34:34] <Daywalker198454> but u have to understand.. :P
[14:34:47] <cradek> you can get a very easy and simple setup like mach3 using stepconf. just ignore your scales.
[14:35:30] <Daywalker198454> did it, but linux should know the position of the table
[14:35:41] <Daywalker198454> not to comp. backlash or something
[14:37:14] <cradek> so like mach3, it is simple to do something simpler than you want
[14:37:19] <ReadError> servos sound like a PITA ;/
[14:37:29] <Daywalker198454> @ ssi and cradek are u often here
[14:37:32] <cradek> step-servos are the worst of all worlds
[14:37:34] <Daywalker198454> PITA???
[14:37:46] <ssi> heh yeah I'm not a fan of step-servos
[14:37:53] <ssi> necessary evil in the mach world
[14:38:16] <Daywalker198454> the mitsubishi´s are pretty fine stuff
[14:38:23] <Daywalker198454> (servo´s
[14:38:27] <FinboySlick> Woah, funky: http://www.youtube.com/watch?v=edJYIarO4R0
[14:38:28] <Tecan> (edJYIarO4R0) "CNC Lathe,CNC Automatic Lathe - HD Video produce by 聖僑資訊 S&J Corp." by "mysjtv" is "Tech" - Length: 0:06:56
[14:38:53] <Daywalker198454> but expensive
[14:40:19] <Daywalker198454> i can drive the mitsubishi´s in torque and velocitymode too
[14:40:54] <cradek> you should run them in velocity mode then
[14:41:04] <ssi> Tecan: I love crazy lathes
[14:41:23] <FinboySlick> ssi: That was me ;)
[14:41:29] <ssi> er right
[14:41:29] <ssi> hahaha
[14:41:37] <ssi> THE ONE WHO ISNT A ROBOT
[14:41:47] <cradek> ideally you'd feedback both positions to linuxcnc and run double pids
[14:42:05] <cradek> (the amps will also need the motor position, that's ok, wire it to both places)
[14:43:05] <ssi> FinboySlick: I can't even imagine what it must be like to program for that thing
[14:43:53] <ssi> also, live tooling polygon turning makes me immensely happy/jealous
[14:44:16] <FinboySlick> ssi: Would suck for one-offs, but optimizing this for output must be awesome.
[14:44:20] <ssi> yep
[14:44:43] <ssi> 11 axis
[14:44:43] <ssi> hahah
[14:47:42] <FinboySlick> When picking a hobby mill, I greatly underestimated the awesomeness that is a tool changer too.
[14:47:58] <FinboySlick> I definitely would have given the tormach more consideration.
[14:48:18] <ssi> yeah the tormach is a nice machine, but it's spendy for what it is
[14:48:21] <ssi> what machine did you end up with?
[14:48:48] <FinboySlick> "http://www.syilamerica.com/machine_x5speed.php
[14:49:07] <syyl_> a toolchanger is incredible usefull
[14:49:08] <syyl_> :D
[14:49:09] <FinboySlick> Considering the price of a Tormach, I'd have had a much nice marchine.
[14:49:13] <ssi> hm
[14:49:14] <ssi> yes
[14:49:26] <ssi> I'm having a hard time getting a sense of scale on that machine
[14:49:30] <ssi> looks small
[14:49:37] <ssi> BF20 sized maybe
[14:49:38] <FinboySlick> It is pretty small.
[14:49:39] <ssi> or smaller?
[14:49:56] <FinboySlick> It's bigger tan an X3
[14:49:56] <syyl_> bigger than a bf20
[14:50:10] <FinboySlick> About 800 pounds with stand.
[14:50:12] <syyl_> what kind of spindle nose does the x5 have?
[14:50:14] <syyl_> collets?
[14:50:16] <ssi> 24k spindle?
[14:50:34] <FinboySlick> 24k spindle, R16 if I'm not mistaken.
[14:50:47] <ssi> R16?
[14:50:49] <ssi> not ER16?
[14:51:03] <FinboySlick> ER, yes.
[14:51:06] <FinboySlick> Not sure on the 16.
[14:51:11] <FinboySlick> 7mm max.
[14:51:15] <syyl_> thats er11
[14:51:18] <ssi> yea
[14:51:19] <FinboySlick> Ah, yes.
[14:51:23] <ssi> tiny
[14:51:25] <syyl_> and pretty small ;)
[14:51:27] <ssi> I have ER16 on my little engraver :P
[14:51:58] <FinboySlick> Given the rigidity, and spindle, I don't think it'd do very well with bigger tools anyway.
[14:52:00] <ReadError> it has a tool changer ?
[14:52:07] <FinboySlick> No.
[14:53:02] <FinboySlick> It's an option on a similarly priced standard X5 though.
[14:53:42] <FinboySlick> I could relatively easily convert the head of the machine to a standard spindle (instead of high speed)
[14:53:59] <FinboySlick> There's a lot of room in that casting.
[14:54:40] <syyl_> i like the fact that it has linear ways
[14:55:02] <FinboySlick> syyl_: You wouldn't like the fact that they're mounted on uneven surfaces though :P
[14:55:10] <syyl_> chinese standard ;)
[14:55:35] <syyl_> at least they dont wear that fast as the soft chinese castiron of normal guideways
[14:55:38] <FinboySlick> It's got no backlash and is silky smooth.
[14:56:05] <FinboySlick> I'll probably take it all appart, lap things nice, adjust and tweak everything that can be and cut my losses ;)
[14:56:32] <FinboySlick> It's just a heck of a lot of work getting there.
[14:56:36] <syyl_> :D
[14:56:51] <syyl_> but at least it looks a bit like a mini-vmc
[14:56:52] <syyl_> :D
[14:56:56] <FinboySlick> Castings are nice and heavy, it *could* be a nice machine.
[14:57:34] <syyl_> the x7 looks cool
[14:57:46] <syyl_> with those heavy sheetmetal waycovers
[14:58:14] <FinboySlick> syyl_: I'd take a magbase and last word indicator to the one I'm buying before signing though ;)
[14:58:39] <syyl_> i would to that with every far-far-east machine.. :D
[14:59:18] <FinboySlick> Mine was far east first, then far west since I bought it from a dealer in Alberta.
[14:59:43] <FinboySlick> I never got to actually see it before it got here.
[15:00:09] <Gammax-Shop> afternoon all
[15:00:32] <Gammax-Shop> ANyone running a hitachi sj200 vfd?
[15:03:29] <ssi> oshi I completely forgot about this little bit of awesomeness
[15:04:13] <Gammax-Shop> Cant wait for my couplers!
[15:04:34] <Gammax-Shop> picked up a hss cobalt 115 peice drill bit set at china freight for 45 bucks...
[15:04:44] <ssi> https://pbs.twimg.com/media/BJxJMQICEAAO_GV.jpg:large
[15:04:56] <ssi> that's supposed to make it on my little lathe and never did
[15:05:01] <ssi> stepper encoder mounts :D
[15:05:20] <syyl_> reminds me of my mill
[15:05:29] <syyl_> i run steppers in closed loop with glas scales ;)
[15:05:44] <ssi> syyl_: I mostly wanted them for the index, for more repeatable homing
[15:05:51] <ssi> but closed loop steppers would be fun too
[15:06:01] <Gammax-Shop> ssi will that make sure the steppers never lose a step?
[15:06:03] <syyl_> its incredible with the glass scales
[15:06:09] <FinboySlick> Ow.
[15:06:14] <ssi> Gammax-Shop: it'll definitely give you a follow error if they do
[15:06:20] <syyl_> i get better than 1/100mm absolute positionaccuracity
[15:06:27] <ssi> syyl_: that's awesome
[15:06:52] <ssi> I bought these encoders a long time ago, thinking the bases would mount on the back of a stepper easily
[15:06:54] <Gammax-Shop> I WOuld do that only if it gave an extra step or sumtin if it missed it.
[15:06:55] <ssi> but it wasn't the case
[15:07:06] <ssi> ended up 3d printing mount adapters for them
[15:07:08] <Gammax-Shop> Or configure it so the steppers were like dc motors ie servos
[15:07:15] <ssi> that's an example of an honestly useful 3d printed object :)
[15:07:20] <syyl_> steppers with encoders are not that uncommon in the industry
[15:07:30] <syyl_> and is it printed on a reprap?
[15:07:33] <ssi> syyl_: yep
[15:07:34] <Gammax-Shop> seriously nice job
[15:07:37] <syyl_> what? :D
[15:07:39] <syyl_> realy?
[15:07:45] <syyl_> a useable object out of a reprap?
[15:07:50] <ssi> it's actually possible to print stuff other than moustaches and fake sunglasses
[15:07:57] <syyl_> :D

[15:09:25] <r00t4rd3d> seems good
[15:12:28] <jdh> same price as keling more or less.
[15:14:03] <r00t4rd3d> i hate to buy 3 more steppers but I dont think the 125oz 2a ones I have now are going to cut it on my new machine
[15:18:01] <andypugh> ssi: I can do polygon turning on a normal lathe.
[15:18:51] <andypugh> Internal too: https://plus.google.com/photos/108164504656404380542/albums/5747722155741347649/5832320925027926978?banner=pwa
[15:20:32] <andypugh> Daywalker198454: For your step-servos what you need is a standard servo setup, but instead of the PID component driving a PWM generator (pwmgen) it needs to drive a step-generator (stepgen) in velocity mode.
[15:21:04] <andypugh> I can't decide whether it is easier to start with a stepper config, or a servo config, to set that up.
[15:21:57] <andypugh> I _think_ what you should do is get it all set up and working as a pure step-system, with no linear slides being used then consider modifying the config to use slides.
[15:22:32] <andypugh> However, if the motors have encoders, I am not really sure what the linear scales add.
[15:22:48] <andypugh> (And I used "slides" a lot of time there where I meant "scales")
[15:24:17] <JT-Shop> enough musicbee, time to take the Giant out into the woods and sweat some
[15:26:05] <andypugh> Take the Midget, and sweat less.
[15:28:38] <L84Supper> https://plus.google.com/photos/108164504656404380542/albums/5747722155741347649/5857937108905406242?banner=pwa blowed up pretty good
[15:32:12] <JT-Shop> crap I think I just made it start rainging but I'm going anyway
[15:32:27] <JT-Shop> I dont' have a Midget just a Giant
[15:33:08] <JT-Shop> last time I had one it had 10 speeds, I don't even know how many this one has...
[15:34:35] <ssi> andypugh: rotary broaching?
[15:41:49] <andypugh> No, active X-slide control.
[15:42:43] <andypugh> L84Supper: Yes, it looks worse now, I fixed the obvious problem with a blown track, then all the caps caught fire.
[15:50:22] <ssi> andypugh: for internal even? impressive
[15:50:28] <ssi> you end up with slightly curved walls that way, no?
[15:51:36] <andypugh> In theory the walls can be any shape, including straight. You do tend to get rounded corners.
[15:52:58] <r00t4rd3d> is that covered under warranty ?
[15:57:48] <andypugh> r00t4rd3d: The 8i20? It was an engneering sample :-)
[16:28:05] <ssi> holy crap how fast can I make this thing go
[16:29:46] <ssi> 3000ipm 100i/s/s works
[16:29:55] <ssi> er no that's 200i/s/s
[16:30:45] <ssi> 3600ipm works, but occasionally stalls in accel

[16:58:33] <r00t4rd3d> should i pack thrust bearings with grease ?
[17:01:05] <ssi> if they're metal race and metal ball, yes
[17:01:11] <ssi> dunno about plastic race ones
[17:01:45] <r00t4rd3d> http://www.cncrouterparts.com/images/IMG_2077.JPG
[17:01:52] <r00t4rd3d> hard to see them but they are all metal
[17:01:58] <r00t4rd3d> needle bearings
[17:02:00] <ssi> yea I'd grease those
[17:02:06] <ssi> something light, like kluber isoflex
[17:02:31] <Aero-Tec> can linuxcnc run more then one spindle?
[17:02:47] <Aero-Tec> variable speed spindles
[17:02:59] <r00t4rd3d> probably with hal and a custom break out
[17:03:04] <Aero-Tec> like the lathe posted above
[17:03:14] <Aero-Tec> cool
[17:03:48] <r00t4rd3d> im just guessing though
[17:04:29] <r00t4rd3d> some type of switched relay and some solder
[17:04:34] <r00t4rd3d> :)
[17:04:50] <r00t4rd3d> you can run a coolant pump and a spindle
[17:04:54] <r00t4rd3d> so
[17:05:18] <ssi> a spindle can be considered an axis
[17:05:49] <ssi> you can do damn near anything in hal
[17:06:01] <ssi> the limiting factor is gonna be user interface related and maybe kinematics related
[17:08:34] <Aero-Tec> so one could run a servo to run 2 spindles?
[17:08:42] <Aero-Tec> 2 servos
[17:08:59] <Aero-Tec> would that be a axis in EMC?
[17:09:41] <Aero-Tec> would be cool to run 2 servos for the 2 spindles of a lathe
[17:10:01] <Aero-Tec> as well as one for active tooling
[17:10:16] <r00t4rd3d> seems andypugh has posted about this
[17:10:27] <r00t4rd3d> http://linuxcnc.org/dapper/emc2/index.php/russian/forum/38-general-linuxcnc-questions/2652-is-driving-a-dual-spindle-mill-possible
[17:10:27] <Aero-Tec> so 3 spindles, maybe more

[17:11:23] <r00t4rd3d> ur gonna break something
[17:11:28] <ssi> NEVRRRR
[17:16:51] <Aero-Tec> it sounds like one can have more them 9 axis in EMC but can only control 9 at one time, is this true?
[17:17:07] <Aero-Tec> that would be so cool
[17:19:07] <andypugh> G-code can only control 9 axes. That is mainly because there are no letters left.
[17:20:10] <Aero-Tec> lot of letters left
[17:20:12] <Jymmm> O_o
[17:20:50] <Aero-Tec> 26 and your only using 9 of them
[17:20:53] <andypugh> But, if all you want to do is send "things" to "places" then the HAL "limit3" component is a complete motion controller. And you can drive it with the G-code analog-out pins.
[17:21:23] <andypugh> They all mean something.
[17:21:45] <andypugh> G, M, S, F and T are clearly "taken"
[17:21:59] <Aero-Tec> true
[17:22:05] <ds3> so are P and Q
[17:22:19] <andypugh> O was the only spare, and got used for loops.
[17:22:29] <andypugh> IJK are arc-centre
[17:22:52] <Aero-Tec> need to do aa ab ac
[17:22:54] <Aero-Tec> lol
[17:23:12] <Aero-Tec> that would expand things some
[17:23:17] <andypugh> Not unambiguous.
[17:23:29] <andypugh> G-code ignores spaces.
[17:24:37] <Aero-Tec> AA,AB,AC.........BA,BB,BC........CA,CB,CC.....................
[17:24:47] <ds3> andypugh: don't threading and macros also use IJK?
[17:25:56] <andypugh> Yes. They can be derived from context.
[17:26:14] <andypugh> But it's hard to see how you can overload an axis move.
[17:26:39] <ds3> trying to say that IJK have other uses beyond arcs
[17:28:48] <andypugh> They can be seen as generic XYZ modifiers, I think?
[17:30:22] <ds3> all the uses of them seem to suggest they are relative version of XYZ

[18:44:53] <JT-Shop> that I know of
[18:45:08] <JT-Shop> I do have some strange music though
[18:45:34] <L84Supper> Madness was a Ska band, then went pop
[18:45:53] <JT-Shop> ok, I had no idea what that was
[18:51:38] <ssi> fedex man is seriously late today :(

[18:58:10] <ssi> true
[18:58:27] <PetefromTn> I am TRYING to use a water heater element with the Z axis drive on my Cincinatti Arrow 500 VMC...
[18:58:55] <ssi> but?
[18:58:56] <L84Supper> PetefromTn: sounds good, any problems so far?
[18:59:00] <PetefromTn> I read the manual on the TSTA-30 teco drive and it indicates a minimum of a 23 ohm resistance
[18:59:24] <Tom_itx> what's the element resistance?
[18:59:26] <L84Supper> at what voltage?
[18:59:35] <PetefromTn> I bought a water heater element that is exactly 24 ohms and is 2500 watt 240v unit
[18:59:48] <L84Supper> sounds good so far
[19:00:14] <Tom_itx> you mounting it under your coffee pot so you can make use of the extra heat?
[19:00:21] <JT-Shop> LOL
[19:00:33] <PetefromTn> I fabricated a small bracket from a piece of square tool steel and tig welded the threaded portion of the element to it and hooked it up from the P to the PC inputs on the TSTA-30
[19:00:46] <JT-Shop> 23, 24 whatever it takes
[19:00:49] <L84Supper> auxiliary water heater
[19:01:30] <PetefromTn> When we powered it up there is ONE setting that I can find that determines the resistor power.
[19:02:04] <PetefromTn> It is CN012 and it WAS set to 60 but we upped it to 300ohms...
[19:03:04] <PetefromTn> When we turned it on there was a strange clicking noise that sounded like a relay was msifiring or something. I quickly powered it down and checked everything
[19:03:14] <PetefromTn> Found nothing in particular.
[19:04:16] <PetefromTn> When I removed the leads to the resistor and reinstalled the little shunt that was there I also changed that parameter back to 60. powered it back up and it STILL made the noise. I shut it off again.
[19:04:45] <PetefromTn> Then I let it sit for awhile and now it seems to work in Z axis drive as I had control with no noise and head goes up and down smoothly and quietly...
[19:05:06] <PetefromTn> I am stumped at what the hell that clicking noise was and why... Afraid to try it again.
[19:05:13] <PetefromTn> any ideas?
[19:05:24] <L84Supper> are there any relays?
[19:05:39] <L84Supper> all semiconductors?
[19:05:43] <JT-Shop> gentlemen I'll leave you with this inspirational song http://www.youtube.com/watch?v=m_WRFJwGsbY
[19:05:43] <PetefromTn> sure three of them but they have nothing to do with this Z drive?
[19:05:44] <Tecan> (m_WRFJwGsbY) "Monty Python Live at the Hollywood Bowl - Philospher's Song" by "Adam Meeks" is "Comedy" - Length: 0:03:57
[19:06:13] <PetefromTn> no mechanical relays...
[19:06:22] <Tom_itx> it wasn't causing an under power condition to trip the relays was it?
[19:07:19] <PetefromTn> how? The relays are used for witching the main contactor, a seal in circuit relay, and the last one is for the spindle motor fan...
[19:07:29] <L84Supper> maybe stuff on the z-axis screws?
[19:07:56] <L84Supper> or was the sound from the control panel?
[19:07:56] <PetefromTn> I never actually moved the axis.... I only energized the servos and heard the noise and quickly hit the E-stop
[19:09:12] <PetefromTn> No it was from the electronics cabinet as far as I could tell. The second time I tried it before reverting to the previous setup I walked back there quickly to see if I could find the source of the clicking but could not tell quick enough and felt scared of the possible problem so I killed the main switch.
[19:09:46] <L84Supper> but it runs fine now?
[19:10:43] <PetefromTn> yeah I actually just lost power from a bad thunderstorm a bit ago so have not been able to check it but once I reverted to the original setup I was able to move everything and checked the coolant pump etc... no issues that I could find... crazy.
[19:11:33] <PetefromTn> Now that the storm has passed I am gonna try to power it up and home everything again. Did not check the spindle motor as I had not messed with it yet.
[19:12:22] <Tom_itx> get a 2nd pair of hands on the control while you stick your head inside the cabinet
[19:12:58] <PetefromTn> yeah good idea...
[19:13:33] <PetefromTn> Really glad I went with the estop circuit that kills power completely.
[19:13:45] <JT-Shop> always a good plan
[19:13:54] <L84Supper> intermittent problem or ? you'll see
[19:14:32] <PetefromTn> yeah I guess so...
[19:15:57] <PetefromTn> what are your thoughts on the element I chose. 2500 watt, 240v, and a measured 24 ohms with the wires hooked up to the resistor. I dunno what the rating would be for it in AIR since it is rated for 25oo watts in water.
[19:16:33] <Connor2> Allot less..
[19:17:09] <PetefromTn> yeah but WHAT?
[19:17:18] <Connor> No clue. :)
[19:17:19] <L84Supper> 10:1 in air so maybe 250W
[19:17:38] <PetefromTn> REALLY well we set that number to 300 in the setting...
[19:18:18] <PetefromTn> again funny thing is I never actually moved the head so the drive should have never sent any power to the resistor yet. I just energized the servos...
[19:18:30] <JT-Shop> water heater elements don't like to be in the air when they get hot, but how long would the breaking resistor be powered up a second or two
[19:18:42] <PetefromTn> if that...
[19:19:25] <PetefromTn> I have one on my 7.5HP spindle motor which is 5.5kw and it is about the same size resistor incidentally and it works fine and honestly does not even get that hot really...
[19:19:25] <JT-Shop> I had to put one on my GS2 VFD to get the spindle to stop quick for tapping
[19:19:44] <PetefromTn> yeah me too...
[19:20:02] <PetefromTn> nice that they are only $10.00
[19:21:50] <L84Supper> 0.6 vs 0.025 W/(m·K)) air vs water 24:1 but that's comparing the heat absorption
[19:21:54] <JT-Shop> aye, that does help when sperimenting
[19:21:58] <Connor> 600 Watts
[19:22:08] <Connor> Water makes no difference...
[19:22:20] <Connor> are the drives 120 or 240 v ?
[19:22:23] <L84Supper> the 2400W is just the rating of 240V with a 24 ohm load
[19:22:31] <cpresser_> PetefromTn: where do you get 10$ resistors?
[19:22:39] <Connor> yea 600W at 120v
[19:28:07] <Tom_itx> is a stovetop element similar resistance?
[19:28:11] <Tom_itx> they work fine in free air
[19:28:36] <Connor> Hot water heater element will be fine.. it's not like they're ran continues duty..
[19:28:42] <Connor> in this application.
[19:28:46] <L84Supper> PetefromTn: whats the 300 setting all about?
[19:28:57] <L84Supper> a wattage setting?
[19:29:21] <Connor> If that's the Watts setting... then.. you need to set it for the rated element.. makes no difference if it's in air or water.
[19:30:04] <L84Supper> the current is still determined by the voltage generated by the motor and the resistance
[19:31:12] <r00t4rd3d> resistance is futile
[19:31:39] <r00t4rd3d> join the force luke
[19:32:32] <L84Supper> should have been the campaign slogan for Bush in 80
[19:32:47] <L84Supper> sorry 2000
[19:33:19] <L84Supper> fits Reagan as well
[19:38:21] <L84Supper> PetefromTn: whats the motor voltage?
[19:38:41] <Connor> I think it's single phase 240v.
[19:38:47] <PetefromTn> Okay just went out there and TRIED it again. Not sure what the hell the difference was other than I set the wattage at 150 in setting CN012 instead of 300. It SEEMS to work properly now. The resistor got hot to the touch like the one on the spindle motor now and I was able to rapid the millhead at twice what I was before. That is all I was able to test thus far.
[19:39:06] <PetefromTn> The motors are 1kw 240v 3 phase I beleive.
[19:39:26] <PetefromTn> cpresser_: they are simple water heater elements you can buy at any hardware stor.
[19:39:30] <Connor> is that a value for wattage ?
[19:39:30] <PetefromTn> store.
[19:39:39] <PetefromTn> apparently..
[19:39:52] <Connor> well @ 24ohms @ 240v = 2400watts
[19:40:11] <Connor> @ 24ohms @120v = 600watts
[19:40:12] <L84Supper> add fins to the heater element
[19:40:41] <L84Supper> increasing the surface area will increase the thermal conductivity
[19:40:46] <PetefromTn> it is not a problem I have them installed in a small vertical space between the column and the electronics cabinet
[19:41:02] <PetefromTn> besides that would be easier said than done really.
[19:41:42] <L84Supper> use a contactless IR thermometer and read the the temp when braking
[19:41:48] <PetefromTn> right now unless I run into that damn clicking again it accomplished the objective. Before If I rapided it at anything more than about 70 IPM it would fault, now I just tested it at 120 and it was working...
[19:41:59] <PetefromTn> Got one I can borrow LOL
[19:42:06] <Connor> I Do.
[19:42:18] <PetefromTn> how did I know that was coming LOL...
[19:42:23] <Connor> ROFL
[19:42:44] <PetefromTn> Oh by the way I thought about that paint, you have been so helpful to me you are welcome to use it as much as you need for free...
[19:42:52] <L84Supper> http://www.harborfreight.com/infrared-thermometer-93984.html
[19:43:12] <PetefromTn> LOL...
[19:43:30] <L84Supper> http://www.harborfreight.com/non-contact-pocket-thermometer-93983.html even cheaper
[19:44:26] <Connor> I have a Ryobi one.. I can't use it in the house.. because the dog hears the BEEP and sees the laser dot and goes nuts wanting to play "Red Bug"
[19:45:02] <Connor> I don't mind playing Red bug with her.. but, she obseses for hours after we're done...
[19:45:06] <PetefromTn> Hmm might have to pick one of those up..
[19:45:26] <PetefromTn> I was gonna use that stuff to paint my Nacra Catamaran sailboat LOL...
[19:45:37] <Connor> http://www.homedepot.com/p/Ryobi-Tek4-Professional-4-Volt-Infrared-Thermometer-RP4030/100671261#.UYrudS7SGtg
[19:45:56] <PetefromTn> Now that it works I am gonna try upping my rapids on the Z and see how far it can go before it faults again...
[19:45:58] <Connor> That's the one I hve
[19:46:16] <Connor> Probably won't at this point..
[19:46:21] <PetefromTn> LOL you likethe spensive ones...
[19:46:37] <PetefromTn> probably won't what?
[19:46:41] <Connor> It wasn't that much when I bought it.. I think it was $40.00
[19:46:46] <Connor> Fault out.
[19:46:55] <PetefromTn> oh that would be nice LOL
[19:47:03] <PetefromTn> one more issue sorted..
[19:47:18] <Connor> Now just the noise generated by the spindle..
[19:47:26] <Connor> Dinner Time.. back in a while.
[19:47:37] <PetefromTn> Got a small 8gb flash drive and gonna try to run some simple code..
[19:47:40] <PetefromTn> enjoy man...
[19:49:33] <r00t4rd3d> i run linuxcnc off a 4gb usb memory stick
[19:56:53] <r00t4rd3d> http://i.imgur.com/0pU8ERT.gif
[19:57:53] <Valen> drift it!
[19:58:01] <Valen> horsie may not be too happy
[20:05:13] <PetefromTn> Okay fellas, I was just out there playing with the setup and I changed that parameter for the resistor output wattage to 150 and was able to up the Z axis rapid speed to like 300 easily, when I went t 340 I got another fault so I am gonna up the resistance setting to 250 again and see if I can get it to go faster without faulting.
[20:05:51] * Tom_itx waits for fireworks
[20:06:01] <Valen> see if you can see why its faulting
[20:06:27] <PetefromTn> I know why its faulting...
[20:16:50] <r00t4rd3d> you?
[20:26:49] <PetefromTn> okay I just was able to rapid that massive millhead up and down the column at 475 IPm without any faults... AWESOME!!
[20:27:03] <Connor> Damn, That's fast
[20:27:20] <Connor> Scary fast.
[20:27:36] <generic_nick|2> yay, my old parts mill is gone!
[20:27:54] <generic_nick|2> cherry picker held together long enough to get it on the trailer at least
[20:28:31] <PetefromTn> yeah you should see it in person LOL
[20:30:05] <PetefromTn> about crap yourself speed rofl..
[20:32:01] <PetefromTn> Honestly it SHOULD do 650 like the other two axes but 475 is faster than the stock setup so I'm happy now,,,
[21:28:37] <PetefromTn> OMFG!! I just ran a simple circular interpolation program with the Cincinatti Arrow. I ran it in air several times to ensure it was gonna do what I wanted it to do and after I felt comfortable with it I decided to FINALLY strap a piece of aluminum to the table to see how she cuts.
[21:30:12] <PetefromTn> I zeroed on a piece of paper and set my Z,X,and Y and held my breath and hit go. It ran a 1/4 inch four flute cutter in .050 DOC passes on a 2" interpolated circle down to half an inch. Flood coolant, spindle on and off, all three axes did exactly what they were supposed to. It was awesome.
[21:32:02] <L84Supper> PetefromTn: what was causing the fault?
[21:32:04] <PetefromTn> The best part is that once I finished the program I raised the millhead up and not expecting anything super precise on my first cut I put my telescoping gauge in the resultant hole and measured it with my calipers and then my best micrometer. The hole is 2.0001!!! I cannot freakin' believe it. It is also about as round as I can measure. I almost crapped my pants when I measured it ROFL...
[21:32:47] <PetefromTn> The fault as I said was from regen when the millhead goes DOWN the column. The head is rather heavy and it was kinda causing the regen to overcome the built in resistor on the drive.
[21:33:47] <PetefromTn> Once I installed the new water heater element resistor and got it dialed in with the drive it now can rapid at almost 500 IPM down the column without tripping the overvoltage error.
[21:34:40] <PetefromTn> Now all I need to do is work with Mike Kilroy on getting the spindle setup correct and I should be able to start really making parts with this monster. The program ran exactly as I wanted so my Sheetcam post is apparently working fine with EMC.
[21:35:12] <PetefromTn> I do want to modify my post so that at the end of a program the millhead goes up to maxZ and the table centers and comes fully forward.
[21:35:25] <PetefromTn> Other than that it ran perfectly. I am STUNNED!!
[21:36:21] <jdh> do you always want it to do that? You could add a pyvcp button to go there, or G28
[21:38:34] <PetefromTn> Honestly I do actually want it to do that after every program because I want to be able to unload and load parts without reaching into the machine to do it or jog it closer to me...
[21:39:47] <Tom_itx> i added that to my post
[21:39:59] <Tom_itx> make sure you put the G28z on a separate line
[21:40:18] <Tom_itx> or you'll end up hitting fixtures
[21:43:19] <PetefromTn> so you do a G28 at the end of the program and it goes to your final home positions which for me would be table in center of X table all the way towards the op in Y and head all the way up in Z...
[21:43:37] <PetefromTn> whatsa G28z?
[21:44:41] <Tom_itx> i do G49 G28 Z0
[21:44:47] <Tom_itx> G28 Y0
[21:45:02] <jdh> you store a position with g28.1 first
[21:45:14] <Tom_itx> well i didn't
[21:45:20] <Tom_itx> i just send it to 0
[21:46:46] <PetefromTn> why Z0? Is that machine coord Z0 perhaps at the top of travel?
[21:46:53] <Tom_itx> yes
[21:47:53] <Tom_itx> but i also use G54 offsets
[21:48:03] <jdh> g28 is absolute
[21:48:06] <PetefromTn> Sheetcam has two parameters for parking and toolchange position. Talking with Art apparently they are both machine coordinates so in theory I could just say go to Z o and whatever y forward is and set those up that way. Should work the same...
[21:48:36] <Tom_itx> they are absolute coordinates yes
[21:48:38] <PetefromTn> I want to use g54 etc for my vises once I get them etc..
[21:48:55] <PetefromTn> damn you should see the finish on this hole...LOL
[21:49:09] <Tom_itx> i set my tool table to match my cad cam tool setup too
[21:49:57] <PetefromTn> actually on my last machine I setup my tool table in mach3 and used no tool offsets in Sheetcam just the tool numbers and descriptions... rather zero..
[21:50:25] <PetefromTn> Would like to do the same with this machine since I will be using a toolchanger eventually on it and getting everything working the way it used to work on the original control.
[21:51:53] <PetefromTn> Tom_itx: hey man where are you?
[21:51:59] <Tom_itx> ks
[21:52:11] <PetefromTn> oh okay... gonna make that linuxCNC meet?
[21:52:11] <Tom_itx> same town as the fest
[21:52:17] <PetefromTn> ROFL
[21:52:22] <Tom_itx> might swing by for a day or so
[21:52:26] <PetefromTn> lucky guys
[21:52:43] <Tom_itx> i go by there all the time
[21:52:46] <Tom_itx> never been inside
[21:52:55] <PetefromTn> nows your chance...
[21:53:33] <Tom_itx> i've been out of the loop for probably 15-20 yrs for the big machines
[21:53:33] <generic_nick|2> what happens if there is a tornado?
[21:53:43] <Tom_itx> you land in a field nearby
[21:54:01] <generic_nick|2> do we need to wear ruby slippers so we can get back to the fest?
[21:54:08] <PetefromTn> Funny I machined that hole and for some reason which I was not sure of it left a little teet in the middle of the hole like a little stick sticking up. I thought it was a problem but then I looked back at sheetcam and it was that way in the toolpath LOL... I had a setting wrong.
[21:54:25] <PetefromTn> Been awhile since I used the program or ran a CNC on it LOL
[21:55:00] <Tom_itx> i use the sherline to 'keep in touch' with cnc
[21:56:30] <Tom_itx> you coming for the week?
[21:56:54] <PetefromTn> who me?
[21:56:58] <Tom_itx> yeah
[21:57:40] <PetefromTn> yeah I wish... I have spent so much time and money on this retrofit I NEED to start using it and making some money to get back in shape over here. No cash for any grand excursions for awhile Im afraid LOL...
[21:57:58] <generic_nick|2> same here... no time either.
[21:57:59] <PetefromTn> Would love to come tho...
[21:58:20] <generic_nick|2> plus if i had the time to travel, i'd be on the rubicon lol
[21:58:24] <Tom_itx> i'd be in the same boat if i didn't live here
[21:58:49] <PetefromTn> I hear ya...
[21:58:55] <generic_nick|2> plus i see my cnc's everyday, the last thing i want to see on vacation is another cnc lol
[21:59:13] <PetefromTn> Damn I am happy that Z axis faulting issue appears to be behind me now.
[21:59:25] <generic_nick|2> was it the drive faulting?
[21:59:39] <PetefromTn> Can't miss mine, it is this HUGE box in the garage LOL...
[21:59:47] <generic_nick|2> or a ferror?
[22:00:53] <PetefromTn> Yeah it has been giving me overvoltage on Z down moves due to the massive millhead weight. I had to switch to the braking resistor from the factory internal one to overcome that overvoltage fault. Honestly I knew that was gonna be the case as Mike Kilroy told me so even before I tried it...
[22:01:14] <generic_nick|2> gotcha
[22:01:41] <PetefromTn> Now that a larger resistor capacity is there I was rapiding the head down and up the column at like 475 IPM....
[22:02:11] <PetefromTn> I backed it back to 100 for these initial program run tests tho. also set the feedrate override to like ten..
[22:03:29] <Valen> I suggest finding a "torture test"
[22:03:45] <Valen> something that will max out all the axies for 10 minutes or so
[22:03:59] <Valen> lots of accelerations, rapids short little hops
[22:04:07] <Valen> all over the bed if you can
[22:04:36] <Valen> we found ours isn't quite right, tune it in tight in one spot and it'll oscillate in another
[22:04:57] <PetefromTn> that is the plan man... still have LOTS of tuning to do here. just getting started really...
[22:05:23] <Valen> still, pretty good when it all works though ;->
[22:05:35] <Valen> don't forget that
[22:05:37] <PetefromTn> I ran it up and down the column via rapid jog about a dozen times this afternoon once I got the resistor to work...
[22:06:00] <PetefromTn> yeah I am totally amazed at this machines capabilities... makes my RF45 look like a toad LOL.
[22:06:07] <Valen> in 4 months time when you are doing something fiddly and its shitting you, remember you have a computer pushing a couple of hundred kg of iron around
[22:06:13] <Valen> ours is a **45
[22:06:19] <Valen> we put glass scales on it ;->
[22:06:25] <Valen> got a pic?
[22:06:32] <Valen> got some machine porn for me?
[22:06:43] <PetefromTn> pic of what?
[22:06:47] <Valen> your machine
[22:06:52] <PetefromTn> the Cinci?
[22:07:14] <PetefromTn> I sold the RF45 awhile back to help fund this monster LOL.
[22:07:31] <Valen> the thing you are doing now
[22:07:57] <PetefromTn> Right now my Spindle drive need tweaking parameters because it does not like pulling the 12k motor RPM...
[22:08:31] <PetefromTn> I will try to take some pictures of the machine and post them to my Photobucket account here in a minute so you can see it. Its a pretty nice looking little machine.
[22:08:37] <PetefromTn> Standby..
[22:08:55] <generic_nick|2> is it designed to go 12k?
[22:12:41] <PetefromTn> yup, 12k motor RPM 6k spindle RPM factory...
[22:16:33] <generic_nick|2> i mean the spindle, the motor is irrelevant
[22:17:29] <generic_nick|2> you'll burn up the spindle bearings pretty fast if you run them at 12k if the machine was designed to run 6k
[22:18:15] <PetefromTn> here is the account...http://s150.photobucket.com/user/matospeter/library/Cincinatti%20Arrow%20500%20Retrofit?sort=3&page=1
[22:18:36] <PetefromTn> <PetefromTn> yup, 12k motor RPM 6k spindle RPM factory...

[22:21:44] <Valen> yes
[22:21:56] <PetefromTn> well that is kinda hard to say really... LOL...
[22:21:57] <Valen> neat conversion there btw
[22:22:04] <PetefromTn> thanks man...
[22:22:19] <PetefromTn> Actually I bought the machine with a blown Z drive for $1300.00....
[22:22:34] <PetefromTn> Spent a couple grand trying to fix the original control system...
[22:22:34] <Valen> damn thats half what we paid for the 45 clone
[22:23:02] <PetefromTn> Then I sold off all the original parts I did not need for like $5600.00 and bought all the new parts...
[22:23:19] <jdh> ice
[22:23:21] <PetefromTn> So basically I must have like $2000.00 or so in it
[22:23:23] <jdh> err... nice.
[22:23:40] <Valen> i hate you ;->
[22:23:41] <PetefromTn> I do believe that I have lost a LOT OF HAIR over it thoo
[22:23:49] <Valen> thats a given
[22:23:50] <jdh> hair is overrted
[22:23:55] <PetefromTn> It has been a real bitch to get it to this point.
[22:24:06] <ssi> still
[22:24:18] <ssi> a lot of people in here would gladly put in the effort and the $2000 :)
[22:24:31] <PetefromTn> If it works and I can use it to make money I will be thousands ahead of what it would cost to buy even a decent working used VMC...
[22:24:58] <Valen> 1
[22:25:06] <Connor> It is a nice machine. I swear, one of these days, I'm going to finish up mine..
[22:25:07] <Valen> this is what $3000 gets you here http://www.ebay.com.au/itm/ROLAND-ENGRAVER-Roland-EGX-20-NEW-IN-BOX-FREE-DELIVERY-NEW-PROTECH-CNC-/251262967648?pt=LH_DefaultDomain_15&hash=item3a80709f60&_uhb=1
[22:25:23] <PetefromTn> Agreed, I can' t complain at all... I love it and if it works the way I hope it will make me some decent cash for my family...
[22:26:01] <ssi> Valen: yea well your dollars are smaller than ours
[22:26:13] <Valen> $au is 1.04 $us
[22:26:16] <ssi> see?
[22:26:19] <ssi> 4% smaller
[22:26:19] <ssi> :D
[22:26:20] <PetefromTn> It has really taken a lot of patience and even more importantly a LOT of good friends helping me or this would have never happened at all...
[22:26:34] <Valen> 1 australian dollar buys you more than one US$
[22:26:42] <Connor> PetefromTn: You look at the motor on the tool changer yet?
[22:26:45] <ssi> pssh you with your math
[22:26:47] <PetefromTn> nope...
[22:27:07] <Valen> toolchanger would be *awesome*
[22:27:10] <PetefromTn> just breathing a sigh of relief that I did not smoke my Z axis drive earlier LOL...
[22:27:22] <PetefromTn> It has a built in 21 tool carousel LOL...

[22:29:15] <Connor> Breaking out my Chop saw makes a HUGE ass mess.
[22:29:22] <PetefromTn> I want a CNC lathe next..... but that one is too big.
[22:29:25] <ssi> Connor: I bought a grizzly 7x12 bandsaw last year and I'm quite happy with it
[22:29:25] <Connor> ssi: I have one.. Just doesn't do well on Alumn
[22:29:38] <PetefromTn> REALLY mine kicks ass in aluminum...
[22:29:46] <PetefromTn> Gotta buy better blades..
[22:29:54] <ssi> that mazak is super hot, but too big for me
[22:30:14] <Connor> Having issues with it.. stupid pulley comes off... it's just a little table top one..
[22:30:15] <PetefromTn> I get mine from Holston gasses and you need to buy Lennox variable pitch aggressive...
[22:30:57] <Connor> http://www.lowes.com/pd_22199-46922-3386-01_0__?productId=3526092&Ntt=bandsaw&pl=1&currentURL=%3FNtt%3Dbandsaw&facetInfo=
[22:31:02] <Connor> one like that.
[22:31:03] <PetefromTn> I got that 4x6 here but I blew the damn motor on it. Then I got the 7x12....
[22:31:20] <ssi> yeah 4x6 bandsaws are mostly shit
[22:31:23] <PetefromTn> Thats a toy and it is also a wood bandsaw...
[22:31:34] <Connor> Yea, that's my point..
[22:31:41] <Connor> It sucks for trying to do alumn.
[22:31:43] <PetefromTn> Actually I used my 4x6 for years with great success....
[22:31:43] <ssi> haha yea that's not a bandsaw
[22:32:01] <ssi> PetefromTn: I did too, so long as great success implies "one piece of metal came off the other piece of metal"
[22:32:05] <ssi> it wouldn't cut anything like straight
[22:32:07] <PetefromTn> It is no 7x12 tho that thing is much more powerful and has liquid coolant onboard...
[22:32:09] <ssi> or quickly
[22:32:10] <ssi> or cleanly
[22:32:40] <Connor> PetefromTn: You need to come over sometime and look at my tiny a$$ shop.. you'll see what I'm dealing with as far as tools...
[22:32:40] <ssi> it was a $200 HF 4x6 though... about the junkiest bandsaw one can get that's still nicer than Connor's fischer-price saw :D
[22:32:44] <PetefromTn> Hmm Mine cut fine with the right blades and proper adjustment. I recall it was a bitch getting it to cut right...
[22:32:59] <ssi> I moved it to the airport, and one of the castings snapped in half during the journey
[22:33:00] <PetefromTn> ROFL...
[22:33:01] <Valen> push harder ;->
[22:33:11] <PetefromTn> you guys crack me up..
[22:33:13] <Connor> I'm for sure not using the right blades for alumn on it.. not sure what to get.
[22:33:21] <ssi> Connor: get a horizontal bandsaw :P
[22:33:41] <r00t4rd3d> most people have no clue how to tune a band saw.
[22:33:45] <PetefromTn> This 4x6 is not that big really. In fact you can use it on a table top without the stand if you want..
[22:34:02] <Connor> http://www.ivdc.com/cnc/shop/ My shop before getting the Mill.. it's were the Radial Arm saw is.. (and the saw is gone)
[22:34:06] <PetefromTn> I found you gotta make that blade TIGHT!!
[22:34:20] <r00t4rd3d> you shouldnt have to over tighten it
[22:34:22] <PetefromTn> Then play with the guides ad nauseum...
[22:34:33] <PetefromTn> You do on the POS 4x6's
[22:34:42] <r00t4rd3d> look at the blade from the top down, when it flattens out, thats enough
[22:34:45] <PetefromTn> My 7x12 is another animal completely...
[22:35:58] <ssi> you guys see my ridiculous 3000ipm plasma jog test earlier?
[22:36:03] <PetefromTn> Love how that Aus ebay site says G'day instead of hello ROFL...
[22:36:10] <PetefromTn> nope...
[22:36:13] <PetefromTn> do tell...
[22:36:14] <ssi> http://www.youtube.com/watch?v=wNo5JsQFgco
[22:36:24] <ssi> linuxcnc+mesa runs this thing SO much faster than it used to
[22:36:51] <PetefromTn> what about the smash smash at the ends of travel LOL...
[22:36:57] <ssi> hahahaha that's the best part
[22:37:00] <ssi> those are just love taps
[22:37:01] <r00t4rd3d> what could you cut at 3000ipm besides paper?
[22:37:07] <ssi> if i really forget and smack it, it's pretty gnarly
[22:37:09] <PetefromTn> AIR.
[22:37:34] <Valen> foam
[22:37:37] <Valen> timber perhaps
[22:37:45] <ssi> thin sheet
[22:37:47] <PetefromTn> Those uprights are kinda flimsy looking no?
[22:37:47] <r00t4rd3d> balsa
[22:37:55] <ssi> dunno about 3000ipm, but you gotta cut pretty quick
[22:38:10] <ssi> PetefromTn: they're 1/4" aluminum, and welded to the gantry
[22:38:12] <PetefromTn> Need to tig weld some more ass on there methinks
[22:38:12] <ssi> it's pretty stout
[22:38:42] <PetefromTn> Just bustin your balls man. LOL
[22:38:48] <ssi> it's actually overbuilt as hell
[22:38:53] <ssi> no cutting forces for plasma :P
[22:39:02] <ssi> the damn table weighs 300lb
[22:39:13] <ssi> I'm kinda dumb, and I made it out of 1/4" wall tube
[22:39:19] <r00t4rd3d> just sloppy cuts unless you spend a million on a plasma
[22:39:39] <PetefromTn> is that belt driven?
[22:39:47] <r00t4rd3d> rack and pinion
[22:39:47] <ssi> rack+pinion
[22:39:59] <PetefromTn> jeez thats smokin'
[22:40:17] <PetefromTn> You wanna see 475 on my Cincinatti millhead. Scared the shit out of me LOL
[22:40:29] <ssi> I need to reduce it more
[22:40:33] <ssi> it's 3:1 reduction
[22:40:41] <PetefromTn> Damn millhead probably weighs as much as my van...
[22:41:03] <ssi> I may go to a smaller pinion... can't really reduce in the belt reduction any further
[22:41:16] <ssi> running the smallest and largest practical pulleys for my shaft sizes
[22:41:35] <Tom_itx> PetefromTn, that coolant is way too clean
[22:41:48] <PetefromTn> yuppers brand spankin new
[22:41:51] <Connor> okay, so how many spot drill before primary drilling under CNC ?
[22:42:07] <Tom_itx> small drills
[22:42:09] <Tom_itx> always
[22:42:20] <PetefromTn> Ya know what amazed me about it is when I made that test cut today I could not see ANY chips anywhere.. Talk about chip evac..
[22:42:26] <ssi> I prefer to spot drill
[22:42:26] <PetefromTn> basically always...
[22:42:31] <r00t4rd3d> i send 1/4 holes all the time
[22:42:32] <ssi> but I don't cnc mill yet
[22:42:58] <generic_nick|2> i always center drill
[22:43:22] <ssi> I want to add a spot drill to my plasma table
[22:43:30] <PetefromTn> Read something on PM yesterday about how it is actually bad to use a center drill as a predrill.
[22:43:31] <Tom_itx> it's just a good idea in general to spot drill first
[22:43:45] <Connor> What?
[22:43:46] <ssi> that was the most disappointing part of plasma for me... small holes don't cut well, and if you pilot them, it hardens the plate enough that it's a bitch to finish drill
[22:43:50] <r00t4rd3d> aspire has peck drill and you can set the parameters
[22:43:53] <Connor> I thought that was what they were for...
[22:43:54] <PetefromTn> You really should use a spot drill that has the same tip angle as the drill you intend to use..
[22:43:59] <ssi> PetefromTn: yea don't use a center drill, use a spot drill
[22:44:16] <Connor> Ahh.. Yea.. I use Center drills all the time..
[22:44:18] <ssi> center drills aren't for spotting
[22:44:18] <r00t4rd3d> i drill with a endmill
[22:44:26] <ssi> they're for drilling 60 degree centers in stock for lathe centers
[22:44:37] <PetefromTn> yes exactly..
[22:44:38] <generic_nick|2> you can get them in different angles
[22:45:09] <PetefromTn> need to pickup a real nice spot drill in the same tip angle as your drills..
[22:45:19] <ssi> I don't bother with the same angle as my drills
[22:45:19] <PetefromTn> Probably a 1/2 incher...
[22:45:23] <ssi> I run a 90 degree spot drill, and that's fine
[22:45:34] <Connor> I'm not a machinist.. So.. I didn't know..
[22:45:34] <ssi> but yea, center drill is the wrong tool for the job
[22:45:37] <PetefromTn> what are your drills?
[22:45:43] <ssi> mostly 118
[22:45:44] <ssi> some 135
[22:46:01] <ssi> my machine shop drills are mostly 118, all my aircraft stuff is 135
[22:46:03] <generic_nick|2> if a hole is that critical, you shouldnt be drilling to a finished dimension anyways.
[22:46:08] <PetefromTn> yeah that is what they were saying it causes the drill to wander upon first contact that way..
[22:46:20] <tjb1> https://www.dropbox.com/s/w1n3gwjsaaaevgm/2013-05-08%2023.31.17.jpg
[22:46:21] <PetefromTn> yeah but it is just good practice.
[22:46:24] <Connor> http://www.harborfreight.com/115-piece-high-speed-drill-bit-set-with-index-528.html
[22:46:27] <Connor> my drill bits
[22:46:43] <ssi> tjb1: awesome
[22:46:47] <PetefromTn> predrill, drill, ream...
[22:46:55] <Tom_itx> bore
[22:46:59] <generic_nick|2> reaming doesnt help hole location
[22:47:14] <PetefromTn> agreed...
[22:47:20] <ssi> spotting does
[22:47:31] <generic_nick|2> not enough
[22:47:32] <PetefromTn> I sold my boring head like an ass with my last machine..
[22:47:45] <Connor> I have one! :)
[22:47:48] <Tom_itx> we used a boring bar on +0.0000 -0.0005 holes
[22:47:52] <ssi> yea everyone needs a good boring head
[22:48:01] <Connor> 3"
[22:48:08] <Tom_itx> but they were ~2-3" holes too
[22:48:09] <PetefromTn> Short drills and reamers work nice...
[22:48:11] <ssi> tjb1: what hotend are you running?
[22:48:20] <tjb1> j-head from makergear
[22:48:23] <ssi> I'd love to have a set of short drills
[22:48:32] <Tom_itx> jobber length
[22:48:37] <ssi> tjb1: ah ok... I have a jhead on my prusa, and a buda on my max
[22:48:44] <ssi> tjb1: your quality looks great
[22:48:46] <generic_nick|2> i only use a boring head on the manual mill. but i make all my fixtures on the manual mill anyways so i dont really need one for the cnc mill
[22:48:50] <PetefromTn> After seeing what this Cincinatti can do with interpolations that may not be too necessary LOL...
[22:49:06] <tjb1> ssi: no, the green is just impossible to see any detail, I still have retraction issues
[22:49:09] <ssi> att
[22:49:10] <ssi> ahh
[22:49:11] <Connor> I needed it for when I was doing manual stuff...
[22:49:20] <ssi> bowden, yea?
[22:49:23] <ssi> you said airtripper I think
[22:49:31] <ssi> 1.75mm?
[22:49:34] <tjb1> yes
[22:50:00] <ssi> what is that model?
[22:50:19] <Tom_itx> PetefromTn, is it still 3 phase/
[22:50:20] <Tom_itx> ?
[22:50:27] <tjb1> http://www.thingiverse.com/thing:5700
[22:50:30] <Tom_itx> you running an inverter?
[22:50:33] <PetefromTn> nope single phase...
[22:50:36] <Tom_itx> mmm
[22:50:37] <generic_nick|2> i've gotten lazy since i got out of aerospace lol
[22:50:45] <ssi> neat
[22:51:00] <Tom_itx> hard to find single phase cnc
[22:51:22] <PetefromTn> yeah but I wanted to run it anywhere without a rotary. I sold my 20HP rotary..
[22:51:29] <ssi> ok I gotta get off my ass and wire the Y motors
[22:51:35] <ssi> heading downstairs, brb
[22:51:41] <generic_nick|2> vfd's for the win
[22:51:44] <PetefromTn> well quit lollygaggin'
[22:51:48] <ssi> sarsly
[22:52:01] <PetefromTn> VFD's rule...
[22:52:18] <PetefromTn> especially if I can get this Hitachi wj200 to cooperate..
[22:52:28] <generic_nick|2> do you have a servo spindle or an ac motor?
[22:53:13] <PetefromTn> 270v 5.5kw 7.5HP 12000 RPM AC spindle motor with timing belt 2-1 reduction to spindle..
[22:53:24] <generic_nick|2> nice
[22:53:39] <PetefromTn> hopefully anyways...
[22:53:52] <generic_nick|2> mine's just 3hp 3 phase ac
[22:54:10] <generic_nick|2> i run it at 120hz
[22:54:20] <generic_nick|2> the mill runs at 6krpm
[22:54:55] <PetefromTn> my RF45 was 3hp 3 ph AC 1725 RPM motor, with belt drive ran it up to 7k or so...
[22:54:55] <generic_nick|2> a bit high for the spindle, but the amount of time i save WAY more than pays for the occasional new spindle bearings
[22:55:26] <PetefromTn> Yeah I am dreading spindle bearing replacement on this monster. Bearings are like $750.00 or so I am told...
[22:55:44] <generic_nick|2> i have a 7.5kw vfd on it with a braking unit and 2.2kw braking resistors. it stops on a dime
[22:55:56] <generic_nick|2> mine's about 400-500
[22:56:05] <PetefromTn> what machine?
[22:56:11] <generic_nick|2> shizuoka ans
[22:56:18] <PetefromTn> Oh yeah thats right...
[22:56:27] <PetefromTn> Wish this was a cartridge spindle...
[22:56:33] <PetefromTn> its not...
[22:56:41] <Tom_itx> my friend had to replace a ball screw end bearing on his a while back
[22:56:47] <generic_nick|2> i stole the spindle out of my kasuga i just scrapped, so i think i can just swap the entire quill into my shizuoka
[22:56:50] <Tom_itx> the factory wanted $1400 for one bearing
[22:56:55] <generic_nick|2> poch
[22:57:00] <generic_nick|2> ouch
[22:57:00] <Tom_itx> he found one for $700
[22:57:06] <PetefromTn> I have a 15HP Hitachi VFD derated to 7.5HP
[22:57:12] <Tom_itx> double row ball bearings
[22:57:23] <PetefromTn> yeah real machines are damn expensive for parts...
[22:57:24] <Tom_itx> 3" ballscrew
[22:57:29] <generic_nick|2> yea, gotta derate them quite a bit.
[22:57:31] <PetefromTn> nutz
[22:57:40] <PetefromTn> half actually
[22:57:56] <generic_nick|2> eh, 33%
[22:58:19] <generic_nick|2> i have a 3hp on my 2hp lathe and it works fine
[22:58:24] <Tom_itx> but he got the machine back for $400 from the shop he sold
[22:58:31] <Tom_itx> with a blown spindle and the bad bearing
[22:58:54] <generic_nick|2> Tom_itx: i have a friend who does machinery dismantling and makes a fortune
[22:59:04] <generic_nick|2> sells all the parts
[22:59:14] <Tom_itx> it would be a fun job i'd think
[22:59:41] <generic_nick|2> i think he hires someone to dismantle them. he just lists the crap on ebay
[23:00:02] <generic_nick|2> has a huge house in the expensive part of san diego
[23:00:10] <Tom_itx> you're the one that showed andy those servo drives
[23:00:15] <generic_nick|2> yes
[23:00:24] <generic_nick|2> those were from somewhere else though
[23:00:50] <PetefromTn> I was amazed at what my old parts from this retrofit sold for.
[23:00:59] <PetefromTn> Paid for everything new and then some...
[23:01:08] <Valen> nice
[23:01:08] <generic_nick|2> nice
[23:01:10] <Tom_itx> well considering what new costs...
[23:01:23] <generic_nick|2> i just trade my old parts to him for stuff i want/need
[23:01:48] <PetefromTn> original drives just to have them refurbished was over a grand each and I bought brand new motors and drives for less than that.
[23:01:49] <generic_nick|2> traded some shit for most of the 4th axis i just got
[23:02:08] <Valen> what are you using to drive?
[23:02:08] <PetefromTn> tell him I want a blown fourth axis for my VMC will ya LOL
[23:02:11] <generic_nick|2> nice
[23:02:22] <generic_nick|2> lol
[23:02:33] <PetefromTn> Valen: talking to me?
[23:02:34] <generic_nick|2> i wish i didnt sell my 5th axis
[23:02:37] <Connor> PetefromTn: I sent you a link for one.. you didn't get it... :)
[23:02:39] <Valen> PetefromTn: yes
[23:02:51] <PetefromTn> Connor: Smartass...LOL
[23:03:04] <PetefromTn> Yeah I am using the Teco servo drives and motors from Machmotion..
[23:03:16] <PetefromTn> missed out bad on that one
[23:03:42] <PetefromTn> Connor: you gotta come over here and see this bad boy run man...
[23:04:04] <Connor> I'll try to.. It's been a busy past few weeks..
[23:04:16] <PetefromTn> no worries...
[23:04:46] <PetefromTn> next victim...http://www.ebay.com/itm/Hardinge-AHC-Automatic-Hardinge-Chucker-CNC-Lathe-/161005644011?pt=BI_Lathes&hash=item257caf28eb
[23:05:42] <generic_nick|2> meh, hold out for an hnc
[23:06:02] <PetefromTn> whazza difference?
[23:06:10] <generic_nick|2> cnc vs air
[23:06:30] <generic_nick|2> isnt that one all air operated?
[23:07:13] <PetefromTn> dunno just found it..
[23:07:33] <generic_nick|2> i dont think it has servos or ball screws
[23:08:03] <PetefromTn> really interesting...
[23:10:29] <ssi> you don't want the ahc
[23:10:34] <ssi> I htink it's actually hydraulic
[23:10:36] <ssi> and crazy
[23:11:21] <PetefromTn> okay.... dunno really. Actually what I want is like a slant bed model with gang tooling perhaps an older Cincinatti milacron.
[23:11:59] <generic_nick|2> http://www.ebay.com/itm/HARDINGE-CHNC-4-CNC-SUPER-PRECISION-CHUCKER-BAR-LATHE-w-BAR-FEEDER-/321118978689?pt=BI_Lathes&hash=item4ac42ec281
[23:12:28] <ssi> yea that's the one you want
[23:12:32] <ssi> hell that's the one I want
[23:12:43] <generic_nick|2> has the bar feeder too
[23:12:53] <generic_nick|2> wish i had one for my hnc sometimes
[23:13:51] <PetefromTn> how big is that bastard?
[23:14:20] <generic_nick|2> small
[23:14:22] <ssi> not that big
[23:14:40] <ssi> 4klb tops
[23:14:44] <generic_nick|2> 2500lbs or so for the lathe. controller is a beast though
[23:14:45] <ssi> probbaly less
[23:14:51] <ssi> hnc is 2500
[23:14:57] <PetefromTn> we're ditching the controller no?
[23:14:58] <ssi> chnc might be a bit more, bigger spindle
[23:15:04] <generic_nick|2> true
[23:15:07] <ssi> you'lll prolly want the drives and power supply out of the control
[23:15:24] <PetefromTn> yeah so I can sell em...
[23:15:33] <generic_nick|2> but the servo might be more of a direct drive so you loose all the varidrive bs
[23:15:41] <generic_nick|2> or use them
[23:15:54] <ssi> true
[23:15:56] <generic_nick|2> i used the hiak amps and the stock servos
[23:16:07] <generic_nick|2> they work great
[23:16:07] <ssi> me too
[23:16:08] <ssi> worked great
[23:16:10] <PetefromTn> what size are the sercos..
[23:16:15] <generic_nick|2> tiny
[23:16:18] <PetefromTn> servos..
[23:16:26] <PetefromTn> 130mm
[23:16:28] <generic_nick|2> 20 amp drives though i believe
[23:16:39] <ssi> hnc is 90vdc
[23:16:42] <ssi> dunno about the chnc
[23:16:52] <PetefromTn> they're not AC drives?
[23:17:00] <generic_nick|2> not the hnc
[23:17:19] <generic_nick|2> but no clue. that chnc is old as balls, so maybe dc as well
[23:18:24] <generic_nick|2> you're not going to be doing big work in that thing so no need for big power
[23:18:58] <generic_nick|2> i havent needed any more power anyways
[23:19:08] <PetefromTn> Im likin this guy..http://www.ebay.com/itm/MORI-SEIKI-SL1A-CNC-LATHE-WITH-TOOL-HOLDERS-TAIL-STOCK-SL1A-/271150510399?pt=LH_DefaultDomain_0&hash=item3f21d4713f
[23:20:07] <generic_nick|2> id get that over the hardinge
[23:20:30] <generic_nick|2> but it is much bigger
[23:20:32] <PetefromTn> gotta find a nice one with a blown control LOL...
[23:20:39] <generic_nick|2> they're all over lol
[23:20:45] <generic_nick|2> that one is a bit overpriced
[23:20:50] <PetefromTn> agreed...
[23:21:00] <PetefromTn> nice machine tho...
[23:21:06] <generic_nick|2> you can buy a running sl6 for 5-6k
[23:21:20] <PetefromTn> only thing I don't like is that Mori parts are spensive
[23:21:30] <generic_nick|2> yea but you dont need them
[23:21:35] <generic_nick|2> they're the best lol
[23:21:36] <PetefromTn> LOL..
[23:22:05] <PetefromTn> thats what I hear...
[23:22:12] <generic_nick|2> i ran an sl0, sl3, and an sl6 for years
[23:22:20] <PetefromTn> good machines?
[23:22:29] <generic_nick|2> great machines. only thing that ever went wrong was the fanuc controls
[23:22:40] <PetefromTn> LOL we can fix that right..
[23:22:57] <generic_nick|2> we had some HARD crashes. didnt evne flinch
[23:23:08] <PetefromTn> I'll bet.
[23:23:26] <PetefromTn> If you arent crashing you arent making anything I guess over time...
[23:23:30] <generic_nick|2> lol
[23:23:47] <generic_nick|2> id like an sl0
[23:23:51] <PetefromTn> I hear they are built like a brick outhouse...
[23:23:58] <generic_nick|2> yep
[23:24:01] <PetefromTn> whats the difference
[23:25:54] <generic_nick|2> the number is the size
[23:26:06] <generic_nick|2> 0 is the smallest, and it goes up from there
[23:26:15] <PetefromTn> obviously...
[23:26:27] <PetefromTn> they all have the same features just smalller
[23:26:35] <generic_nick|2> more or less
[23:26:39] <PetefromTn> all slant bed, all tool turret
[23:26:48] <PetefromTn> do they all have tailstock
[23:27:03] <generic_nick|2> i ran a newer mori lathe, like a 2006 model. it was ok but i think the older ones were beefier
[23:27:05] <PetefromTn> whats the HP on SL1
[23:27:14] <generic_nick|2> all the ones we had did
[23:27:22] <generic_nick|2> no clue on numbers
[23:27:38] <PetefromTn> Sure seems like a sweet machine tho...
[23:27:45] <generic_nick|2> yep
[23:27:49] <PetefromTn> Can you get a collet closer?
[23:28:00] <generic_nick|2> no clue. we just had chucks
[23:28:11] <PetefromTn> pneumatic?
[23:28:20] <generic_nick|2> hydro
[23:28:31] <PetefromTn> are the machines hydro?
[23:28:43] <generic_nick|2> servo
[23:28:56] <PetefromTn> so a pump setup just for the chuck?
[23:29:09] <generic_nick|2> yes and maybe turret, i dunno
[23:29:27] <PetefromTn> don't like hydro stuff... too messy and complicated...
[23:29:34] <generic_nick|2> and tailstock
[23:29:45] <generic_nick|2> never had a problem with it
[23:30:08] <generic_nick|2> all power chucks willl bte hydro
[23:30:12] <generic_nick|2> be*
[23:30:58] <PetefromTn> I am gonna want a nice pendant for my Cincinatti Arrow here soon I think. Gotta find one that has an MPG on it that plays nice with LinuxCNC..
[23:31:04] <generic_nick|2> you need to be able to adjust the pressure. same with the tailstock
[23:31:28] <PetefromTn> aah...
[23:33:26] <PetefromTn> Well I am gonna hit the hay here fellas. Nice chatting with you.. peace
[23:33:59] <generic_nick|2> nite
[23:37:06] <ssi> mhaberler: excellent find!
[23:37:48] <mhaberler> maybe that helps to fill in the quadrature decoder missing spot in Charles' driver
[23:38:00] <ssi> I'm gonna jump into the PRU code here real soon
[23:38:04] <ssi> PWM outs would be good to have too
[23:38:42] <mhaberler> yes, but maybe investigating the existing PWM's first might make sense before doing new ones
[23:38:52] <ssi> true
[23:38:56] <mhaberler> I didnt look into those though
[23:39:10] <ssi> I have a couple applications for the BBB driving machines
[23:39:24] <mhaberler> stepper?
[23:39:30] <ssi> one is redoing my g0602 lathe, which requires two stepgens, an encoder counter (three would be nice), and a pwm out
[23:39:33] <ssi> yea
[23:39:44] <mhaberler> how many ppr
[23:39:57] <ssi> the spindle encoder is 32 I think
[23:39:58] <ssi> pretty coarse
[23:40:01] <ssi> it's homemade
[23:40:26] <ssi> https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-frc1/205204_655375525742_5631970_n.jpg
[23:40:39] <mhaberler> so that wont be more than say 3000 transitions/sec then
[23:40:50] <ssi> it'd be more than that at 3000rpm!
[23:40:55] <mhaberler> oh
[23:41:30] <ssi> I'm hoping that two prus is enough to run four stepgens and four encoder counters at least
[23:41:34] <ssi> but maybe I'm overestimating the hardware
[23:41:37] <mhaberler> well that'd be a bit pushing the envelope with a soft encoder and base thread
[23:41:45] <mhaberler> oh absolutely, enough bang there
[23:42:13] <mhaberler> you need to talk Charles into providing the hooks for other tasklets in the PRU, it might be there already
[23:42:54] <ssi> yea I dunno how configurable pru code is gonna go
[23:43:04] <ssi> might be we just end up with a bunch of different programs, and you load the one you want
[23:43:46] <mhaberler> dont think that will scale; I guess its going to be one binary with all functions assembled in, and select the ones you need based on a config mask
[23:43:59] <ssi> that may work
[23:44:10] <ssi> are there limits to the binary size in the PRU?
[23:44:11] <mhaberler> mask bit set -> execute corresponding tasklet
[23:44:16] <mhaberler> 12k I think
[23:44:33] <mhaberler> pretty hard to exceed with assembly code.. I wouldnt understand it
[23:44:45] <ssi> it's also complex because what pins the PRU grabs (and therefore become unavailable to gpio driver etc) will change based on the tasklets you want
[23:45:05] <mhaberler> yes, that's why the bitmask is needed
[23:45:19] <ssi> yeah I guess that won't be a problem if it's a hal driver that's setting up the PRU
[23:45:44] <mhaberler> that is the case now; HAL driver does incantations, then load PRU binary and start it
[23:45:45] <ssi> pru driver loads first, based on config strings tells pru which tasklets to run, and then marks those pins clamed
[23:45:52] <mhaberler> yes
[23:45:58] <ssi> and honestly the order doesn't even matter
[23:46:11] <ssi> if the gpio driver loads first and claims pins that the pru needs, pru driver will fail
[23:46:16] <mhaberler> that's the point of the bitmask
[23:46:47] <mhaberler> what we do need is a inter-driver convention how to correlate bit number and GPIO pin
[23:47:00] <mhaberler> that's where your offset comes in
[23:47:03] <ssi> keep it simple
[23:47:17] <ssi> two 46 bit masks
[23:47:26] <ssi> first one is P8, second one is P9
[23:48:05] <mhaberler> so we need say macros to convert pin# to bitpos and vice versa
[23:48:21] <ssi> yeah
[23:48:34] <ssi> and those macros can be specific to whatever representation the driver in question uses
[23:48:39] <mhaberler> hm, another list item..
[23:49:51] <ssi> so there's an 8k block of ram in the pru that you can write to from linux code
[23:50:02] <ssi> I guess the strategy is to write control data into that space on the servo-thread
[23:50:09] <ssi> and let the PRU run its own base thread based on your control data
[23:51:27] <ssi> haha gotta love college students
[23:51:28] <ssi> So, if you need precise timing, or more rapid access to a certain GPIO pin, this is a route you might want to look into. There are a few suggestions listed above that might be interesting to see come out of using the PRU. However, if you do not require precisely timed events or faster access to GPIO pins, you might want to consider just using C on the main processor. Much of the information needed to access certain parts of the PRU and the hardware from
[23:51:42] <ssi> "Using the PRU is hard, so we recommend you don't unless you need to, cause it's scary and hard"
[23:52:05] <ssi> also, who starts a paragraph in a research paper with "So, "
[23:52:07] <ssi> :D
[23:53:55] <ssi> http://blog.pignology.net/2013/05/getting-uart2-devttyo1-working-on.html
[23:53:57] <ssi> this is useful too
[23:53:59] <ssi> from Dave's post
[23:55:00] <ssi> oh weird... now I see how you apply an overlay
[23:55:58] <ssi> I'd love to get to a point where we can design some hardware breakout capes that have signal conditioning for specific tasks, and give it an eeprom so it'll load its dto automatically at boot
[23:56:03] <ssi> that would be pretty dang slick
