#linuxcnc | Logs for 2014-01-25

[00:01:14] <heathmanc> just one setting i don't understand, this A005 setting
[00:01:25] <Einar_> Try setting F002=10.
[00:01:26] <heathmanc> [AT] analog type
[00:01:33] -!- Tecan has quit [Ping timeout: 252 seconds]
[00:02:07] <WalterN> anyone use OpenPLM before?
[00:02:29] <heathmanc> no change
[00:02:43] -!- Thetawaves [Thetawaves!~Thetawave@186-51-178-69.gci.net] has joined #linuxcnc
[00:03:12] <heathmanc> lol, so easy before i started to control it with linuxcnc, change the frequency and hit run!
[00:03:21] <jdh> WalterN: I have to use Enovia
[00:03:47] <jdh> I'm sure there are more obtuse and absurd ways of doing things, but I've never seen them.
[00:04:16] <Einar_> Please keep linuxcnc out of the equation until you can control it using jumper wires and preferrably a pot or adjustable PSU.
[00:04:58] <heathmanc> oh, I know it's not me and linuxcnc
[00:05:12] <heathmanc> it's just me
[00:05:18] <WalterN> jdh: never heard of it before, nor have I used any PLM type of software before... as I understand it, they are designed to keep track of drawings and programs and stuff for one specific part?
[00:05:52] <jdh> WalterN: more or less. tracks everything related to a part
[00:06:11] <WalterN> jdh: alright, and thats exactly what I need... (heh)
[00:06:59] <jdh> parts, specs, changes, revs, etc
[00:07:04] <WalterN> yeah
[00:07:25] <WalterN> jdh: know of any good ones besides OpenPLM thats open source?
[00:07:33] <jdh> only one I've ever heard of.
[00:07:44] -!- Tecan [Tecan!~fasdf@unaffiliated/unit41] has joined #linuxcnc
[00:07:51] <jdh> it's not a trivial undertaking and requires robust infrastructure
[00:08:12] <WalterN> what? setting up OpenPLM?
[00:08:27] <jdh> no, writing a PLM package
[00:08:36] <WalterN> oh, yeah... heh
[00:08:47] <jdh> but, you need good DB practices. backups, journaling, etc.
[00:10:15] <WalterN> yeah, at the moment I have a debian minimal install sitting here on a raid1 array doing nothing... I'll figure out backup once I get the PLM software working
[00:10:43] <Einar_> One hour past midnight here. I'll go counting sheeps.
[00:10:55] -!- Einar_ has quit [Quit: Leaving]
[00:11:07] <heathmanc> I will try to use the hitachi software so I can look at this easier
[00:12:36] <WalterN> bleh
[00:12:46] <WalterN> it seems OpenPLM does not have an IRC channel
[00:12:57] * WalterN rages
[00:13:06] <jdh> ask for a refund
[00:13:27] <WalterN> they want me to sign up or something to download the software
[00:13:44] <WalterN> to the "OpenPLM Professional Network"
[00:14:07] <WalterN> I wonder if its in apt
[00:14:26] <micges> heathmanc: what is your wiring atm between inverter and lcnc?
[00:15:11] -!- terabyte- has quit [Quit: terabyte-]
[00:15:12] <heathmanc> i have a 7i48, with analog out + going to "O", and analog ground to "L"
[00:15:33] <heathmanc> and then I am jumpering the fwd/run at the moment.. P24 to 1
[00:16:32] <micges> do you have 24V logic powered on inv?
[00:16:51] <heathmanc> i am using the 24v from the VFD for logic
[00:16:56] <heathmanc> at the moment
[00:17:11] <heathmanc> once i sort this out, the 7i37 com will provide the fwd/rev inputs
[00:17:27] <micges> ok
[00:18:15] <micges> what pin is have 24V output?
[00:18:24] <heathmanc> P24
[00:18:38] <heathmanc> PLC and L are jumpered for sourcing input
[00:19:03] <micges> ah ok I got it
[00:20:17] -!- Jeebiss_ has quit [Ping timeout: 272 seconds]
[00:22:05] <micges> got shortbar between PLC and L pins?
[00:24:37] -!- Nick001 has quit []
[00:27:16] <micges> ok so you have analog in, and forward
[00:28:33] <micges> isn't needed to be 'start' pin somewhere?
[00:28:55] <WalterN> jdh: ugh... they want me to buy it in order to download the latest version.
[00:29:25] <WalterN> where is the source code? I'll compile it myself
[00:29:49] <heathmanc> yes, shortbar between plc and l
[00:29:54] <heathmanc> analog in and forward
[00:30:28] <micges> ok I don't see any other pin you should connect
[00:30:31] <WalterN> when I click on 'become a professional member' thing, it leads me to a web page that does not exist
[00:30:54] <heathmanc> right, so I assume it's a vfd config problem

[00:40:45] <Tom_itx> ?
[00:41:27] <WalterN> Tom_itx: oh, for the source files... it seems like they might have abandoned the website... doing some more searching

[00:52:46] <zee-ipad> hi
[00:53:50] <WalterN> oi
[00:55:33] <zee-ipad> im so confused with the dir+ dir- pul+ pul- wiring on my stepper driver
[00:55:36] <zee-ipad> http://www.automationtechnologiesinc.com/wp-content/uploads/downloads/2012/08/KL-8070D.pdf
[00:56:30] <zee-ipad> on pg 7 in that pdf they clearly show that you need 5v vcc input to dir+ and pul+
[00:57:06] <zee-ipad> http://probotix.com/manuals/PBX-RF_manual.pdf
[00:57:29] <zee-ipad> in my breakout board im not sure where i should be picking up the 5vdc from
[00:58:06] <zee-ipad> im not using the pbx headers but rather using the screw terminals
[01:03:34] <zee-ipad> looks like i need to use the pbx headers to get 5v blah

[14:26:06] <archivist> lightening to thunder time is rather short
[14:26:35] <Deejay> get outside and let a kite fly :D
[14:28:46] <Jymmm> archivist: Got your LinuxCNC Approved lightening rod(s)?
[14:30:02] <archivist> moving away now, it is up to 3 secs

[14:33:01] -!- b_b has quit [Changing host]
[14:34:33] <archivist> its something like that
[14:38:30] <mozmck> Isn't it the speed of sound? In that case it is 4.6891 seconds per mile :)
[14:40:40] <Jymmm> When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck. If it takes 10 seconds for the thunder to roll in, the lightning struck about 2 miles or 3 kilometers away.
[14:41:50] <Jymmm> http://science.howstuffworks.com/nature/climate-weather/storms/question182.htm
[14:42:23] <Jymmm> 1 mile = 5 seconds, 1KM = 3 Seconds

[15:06:14] <Tom_itx> one hit a tree not 30' from the house late last year
[15:06:55] <Jymmm> Tom_itx: do you have lightening rods on the house?
[15:06:59] <Tom_itx> brown stripes all down the tree and unearthed the ground around it's base
[15:07:27] <Tom_itx> popped the bark off where it hit

[18:10:22] <Loetmichel> IchGuckLive: that sounds not so good.
[18:10:31] <IchGuckLive> about neer exact 2"
[18:10:32] <Loetmichel> the mechanics i meant
[18:10:46] <IchGuckLive> Loetmichel: at this low speed
[18:10:49] <Tom_itx> how did you determine that?
[18:10:51] <Loetmichel> something in the drive train is resonating
[18:11:07] <IchGuckLive> at over 1500mm/min lower noice

[18:12:31] <IchGuckLive> if in the green glase the Red Laser beam is near white then you are in focus

[18:34:08] <IchGuckLive> just ask if we can help you
[18:35:17] <onyedi> hello, can anyone help me test a dual drive setup? My x axis has dual steppers, but i cannot seem to test both of them at the same time, when i run the test only one stepper is driven. Any suggestıons?
[18:36:07] <onyedi> x axis runs fine in linuxcnc main
[18:36:26] <IchGuckLive> onyedi: gantry

[18:36:55] <CHNCguy> Hey Hey Guys ;)
[18:37:09] <IchGuckLive> onyedi: plese post your hal to pastebin
[18:37:31] <IchGuckLive> Loetmichel: whar Break out board do you use
[18:37:34] <onyedi> i dont have it with me sorry it is at work
[18:37:50] <IchGuckLive> ok what brek out board do you use
[18:38:01] <onyedi> pmdx 126
[18:38:21] <IchGuckLive> nice and the drivers are
[18:38:38] <onyedi> leadshine dm876
[18:38:39] <IchGuckLive> i guess you use 2 drivers for your X
[18:38:52] <CHNCguy> I got a pretty simple question: I am running mesa 7i76/5i25 and need to control spindle speed and direction. How would I effectively be able to reverse the motor direction for rigid tapping on a cnc lathe? 0-10vdc for speed, I understand that, but as for switching to go into reverse how does linux handle that? An output? A Relay? Thanks :D
[18:39:40] <onyedi> yes
[18:39:45] <IchGuckLive> CHNCguy: your VDF has a extra pin for that
[18:40:17] <onyedi> IchGuckLive: yes each stepper has its own drive
[18:40:31] <IchGuckLive> onyedi: ok then its easy
[18:41:40] <CHNCguy> let me scroll through the manual, http://www.soonwell.com/ebay_file/user_manual/Inverter-Manual.pdf
[18:42:29] <IchGuckLive> onyedi: you only need to output step and dir to 2 more pins
[18:42:56] <onyedi> IchGuckLive: i setup the pins 2-3 and 6-7 for the x axis, the gantry runs fine when jogged , the problem is with the testing
[18:43:14] <CHNCguy> Hey IchGuckLive, Can u look at 4.2 in the manual, I don't really see a pin... for reverse
[18:43:47] <IchGuckLive> onyedi: what woudt you like to test
[18:43:59] <IchGuckLive> onyedi: 2 diles
[18:44:05] -!- Komzzzpa has quit [Ping timeout: 272 seconds]
[18:44:09] <IchGuckLive> move 120+mm forward
[18:44:13] <IchGuckLive> and reverse
[18:44:30] <IchGuckLive> then setup the dilas and do it again
[18:44:38] <IchGuckLive> and you got your backlash
[18:44:58] <IchGuckLive> onyedi: on homing only home on one side
[18:45:16] <IchGuckLive> CHNCguy: i m on
[18:45:43] <onyedi> IchGuckLive: i would like to test using Stepconf and find the best velocity and acceleration ratio, so when i try to test the X axis it just moves only one stepper not both of them
[18:46:18] <onyedi> IchGuckLive: but main program runs fine as well as jogging manually
[18:46:26] <IchGuckLive> onyedi: use nomal entry
[18:46:27] <onyedi> IchGuckLive: cuts are fine also
[18:46:39] <IchGuckLive> onyedi: what V is on the stepper
[18:46:49] <IchGuckLive> Driver !
[18:46:55] <onyedi> 60v
[18:47:09] <IchGuckLive> ok cable length
[18:47:18] <onyedi> 2m
[18:47:29] <IchGuckLive> you are good to go 5m/min
[18:47:37] <onyedi> yes
[18:47:51] <IchGuckLive> use 2000 2000 5000 8000 for timing
[18:47:53] <onyedi> it goes 5m flawless
[18:48:15] <IchGuckLive> and 85mm/sec with 250mm/s²
[18:48:26] <IchGuckLive> then you are ok
[18:48:35] <IchGuckLive> why woudt you like to go faster
[18:49:23] <onyedi> let me rephrase the problem; when using Stepconf, X axis test only moves one stepper.
[18:49:24] <IchGuckLive> onyedi: open up the INI and change the Baseperiod down from 100000 to 30000
[18:49:52] <IchGuckLive> onyedi: that is normal as it internal did not use HAÖL
[18:50:09] <IchGuckLive> the interpreter makes its own config
[18:50:24] <IchGuckLive> so its not posible to test gantry in stepconf
[18:50:29] -!- gonzo__ has quit [Read error: Connection reset by peer]
[18:50:32] <onyedi> ok so there is no way to use the Stepconf to test a dual stepper gantry?

[18:50:56] <IchGuckLive> its only a setup not a test

[19:00:01] <CHNCguy> well i think its, check out page 30 in the manual P3.08
[19:00:14] <CHNCguy> it says 2-wire control
[19:00:33] <IchGuckLive> P3.08
[19:00:53] <CHNCguy> how would I go about and set it up?
[19:01:46] <pcw_home> Yeah but FOR/REV 2 wire mode unfortunately the 7I76 spindle control outputs only support ENABLE/DIR
[19:02:12] <IchGuckLive> he can use GPIO
[19:02:46] <archivist> there seems to be a 0= -100% and 10=100% mode
[19:03:25] <CHNCguy> which would be best? And how would I set it up?
[19:03:47] <CHNCguy> You guys are awesome by the way :D
[19:03:48] <IchGuckLive> onyedi: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?About_Charge_Pumps
[19:06:24] <IchGuckLive> onyedi: did you set correct mode on the pmdx
[19:06:25] <archivist> see page 43 for a graph going through 0
[19:07:17] <pcw_home> seems possible but not clear how to setup:
[19:07:19] <pcw_home> 2:3-wire control mode1: X4 is the multifunctional input terminal. Run command is given by X1, direction command by X2.
[19:07:20] <archivist> seems to be the PID mode
[19:08:01] <onyedi> yes I did config 1 is on (charge pump wişth normal mode), i assumed chargepump will work with just setting the pin 17 as chargepump in linuxcnc
[19:09:09] <CHNCguy> archivist, so if I output 5v it will be 0 or stopped, and 0v is max -100% (is this reverse?) and 10v is 100% (is this forward?)
[19:09:10] <IchGuckLive> so open close close 1-3
[19:09:31] <onyedi> yes exactly
[19:09:49] <onyedi> i can make it work with another software
[19:09:53] <archivist> CHNCguy, that is my assumption yes, I think some experimentation is needed
[19:09:55] -!- motioncontrol has quit [Remote host closed the connection]
[19:10:40] <onyedi> and when i turn config 1 off, it works as expected without the chargepump
[19:11:20] <onyedi> wikipage says i need to loadrt charge_pump
[19:11:33] <IchGuckLive> did you do that
[19:11:38] <onyedi> nope
[19:11:48] <IchGuckLive> then it wont work
[19:11:53] <onyedi> its a fresh installation of ubuntu and linuxcnc
[19:12:08] <CHNCguy> Yes I agree, so how exactly does linuxcnc handle to output with the 5i25 and 7i76? Meaning when I say S5000 (m3 clockwise) in gcode, how will it know to output 10vdc on spindle output pin. And If Input S5000 m4 (clockwise), it will out put 0vdc?
[19:12:08] <onyedi> i just installed it today and gave it a try
[19:12:15] <IchGuckLive> ok

[20:21:47] <pcw_home> 2:3-wire control mode1: X4 is the multifunctional input terminal. Run command is given by X1, direction command by X2.
[20:22:32] <CHNCguy> which page are u refering too?
[20:23:48] <pcw_home> bottom of page 45
[20:24:46] <CHNCguy> Yes I see that, but it wants a logic of relays to sense dir and stop commands, how would I set up linux to make this work?
[20:24:52] <CHNCguy> i have 7i76 board
[20:25:20] <pcw_home> No relays needed if it can do ENABLE/DIR
[20:26:07] <CHNCguy> do you know what I would need to hook up? I see the 3 wire but i am confused as how to get it to work
[20:26:14] <CHNCguy> on page 46
[20:26:14] <eric_unterhausen> all of the vfd's I have ever bought have forward/reverse/stop
[20:26:22] <pcw_home> I would play with a couple switches and seen if it can do ENABLE/DIR mode
[20:26:28] <eric_unterhausen> so it's not really enable/dir
[20:27:16] <CHNCguy> Hi eric, i have similiar experiences, have u looked at page 45 http://www.soonwell.com/ebay_file/user_manual/Inverter-Manual.pdf in this manual?
[20:27:29] <pcw_home> Most can do enable/dir but not all
[20:30:06] <CHNCguy> I think I can set up some relays for the fwd rev logic. But this would all be so much easier If I can just use this lower limit function on page 43
[20:30:54] <CHNCguy> where 0v from linux on spindle output voltage pin = -100% (rev) on the drive, and 5v= 0 (stop) and 10v = +100 (fwd) on the drive
[20:31:03] <eric_unterhausen> too bad their 2-wire mode is so stupid
[20:31:06] <CHNCguy> can this be done within linux and the hal?
[20:31:16] <CHNCguy> I know right.......
[20:31:51] <pcw_home> I think 3 wire mode 1 is correct if the text is correct
[20:32:57] <pcw_home> (the mode description text is _above_ the drawing)
[20:33:22] <eric_unterhausen> 3 wire mode description is really hard to understand

[20:34:13] <CHNCguy> I know... so let me get this straight, if sb1 is closed, x1 gets a com signal and it goes forward
[20:34:38] <pcw_home> it says X1 is run and X2 is direction in that mode
[20:34:42] <CHNCguy> if sb3 is closed and x2 gets the signal for com, it goes reverse
[20:35:11] <CHNCguy> ?
[20:35:42] <CHNCguy> So then do I have to switch sb1 and sb2? and sb2 and sb3 at the same time? it says stop command by normally closed sb2
[20:35:48] <pcw_home> 2:3-wire control mode1: Run command is given by X1, direction command by X2, X4 is normally close input.
[20:35:57] <pcw_home> (from page 45)
[20:37:51] <zeeshan> guys
[20:38:04] <zeeshan> should the step and dir signals be getting constant +5v when the breakout board is powered?
[20:38:05] <CHNCguy> that would only give me fwd or rev? But not both...
[20:39:23] <pcw_home> I am assuming direction means direction
[20:40:08] <eric_unterhausen> that's just crazy talk
[20:40:17] <pcw_home> zeeshan: depending on step polarity and current direction, possibly
[20:40:33] <CHNCguy> ahhhh I got it LOL tricky beast. Check this out, page 45. 0:2-wire control mode 1, if I output no change to k1 and k2 the drive is in stop mode
[20:40:42] <CHNCguy> if I close k1 it goes forward
[20:40:50] <CHNCguy> if i open k1 it stops
[20:40:55] <zeeshan> pcw_home: do you work at automation technologies?
[20:40:56] <zeeshan> :)
[20:41:00] <CHNCguy> if I close k2 it goes rev
[20:41:08] <CHNCguy> if I open k2 it stops
[20:41:18] <CHNCguy> right?
[20:42:07] <eric_unterhausen> yes
[20:42:17] <CHNCguy> whoot! lol
[20:42:59] <pcw_home> Thats a for/rev mode so you need a relay to do that with the 7I76
[20:43:00] <pcw_home> It looks like it may support a DIR/ENABLE mode (3 wire mode 1)
[20:43:53] <pcw_home> (but I would try with a couple switches)
[20:43:56] <eric_unterhausen> I would set up 3 wire mode one and test it
[20:44:37] <CHNCguy> gotcha, thanks guys, so I would just set up the hal pins net spindle-fwd motion.spindle-forward => parport.0.pin-16-out
[20:44:37] <CHNCguy> net spindle-rev motion.spindle-reverse => parport.0.pin-17-out
[20:45:05] <pcw_home> Umm I thought this was for a 7I76
[20:45:11] <CHNCguy> or change the pins to what I want, i have 24vdc for the IO's it will give me 24vdc out on those pins right?

[20:46:25] <CHNCguy> What pins would they be GPIO something something right?
[20:46:32] <pcw_home> Theres a bit more work because the spindle speed value is signed

[20:47:36] <CHNCguy> signed? Not sure what u mean
[20:47:59] <pcw_home> basically you wire the motion spindle_on pin to 7i76_spinena and motion spin forward (or rev) to 7I76 spin_dir
[20:48:57] <pcw_home> but you need to put the spindle speed through a absolute value component
[20:48:59] <pcw_home> (since it will be negative for reverse spindle speeds)
[20:49:34] <CHNCguy> the voltage will be negative on the output to spinena?
[20:49:51] <CHNCguy> If so how would I include that absolute value component so it only outputs positive?

[21:57:41] <MrSunshine> so i guess i was right it was the runout of the spindle causing the problem =)
[21:58:16] <MrSunshine> from 0.1mm runout to 0.01mm runout now (runout in spindle cone is 0 but ER collet has runout) ALOT of vibrations is gone from the spindle and sounds alot nicer =)

[22:11:33] <CHNCguy> small microswitch from radioshack or ebay (the one with the small roller on the end)
[22:11:52] <Loetmichel> cheap as fuck and less than 0,01mm error when run over sideways
[22:12:12] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=7414
[22:12:18] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=7411
[22:12:50] <Loetmichel> i.e: less than 2 steps difference when checking the position multiple times
[22:13:09] <heathmanc> seems fair enough
[22:13:10] <Loetmichel> even in that dirty conditions
[22:14:02] <Loetmichel> CHNCguy: these switches with the roller at the end have some play usually, not so good actually for reference switches.
[22:14:21] <heathmanc> will be using an index pulse with them
[22:20:40] <zeeshan> Loetmichel: do you like proximity limit switches?
[22:22:33] <CHNCguy> well limit switches ;)
[22:23:00] <CHNCguy> JT-shop, does our encoders have the index pulse? Do you have the wiring info for the encoders?
[22:26:56] <heathmanc> what I would prefer, is a round plunger type, small

[23:30:35] <CHNCguy> thanks for all the help JT and the gang ;) Till next time ;D

[23:30:43] <JT-Shop> Jymmm, it don't work that way
[23:30:49] <JT-Shop> CHNCguy, have fun
[23:30:49] <rob_h> CHNCguy, CHNC encoder stock is 4000PPR btw
[23:31:04] <JT-Shop> and thank rob_h for the spindle hal
[23:31:06] <rob_h> axis ones cant rember what they are but they are the same, fix the bracket
[23:31:11] <Jymmm> JT-Shop: That's not what she said
[23:31:13] <CHNCguy> it is?
[23:31:25] <rob_h> u have fanuc motor still?
[23:31:34] <CHNCguy> ya
[23:31:42] <CHNCguy> the 200+lb monster motor LOL
[23:31:43] <rob_h> i saw your VFD question above, i just got in was reading over logs real fast
[23:31:52] <CHNCguy> any help?
[23:31:57] <rob_h> says ur drive is close loop vector only
[23:32:08] <CHNCguy> You can set it to vectorless
[23:32:33] <rob_h> mode where does not use a ecndoer yea openloop... closeloop needs encoder feedback from motor
[23:32:39] <CHNCguy> there is 2 settings, there is an auto tune in the beginning manual to set it for vectorless
[23:32:55] <CHNCguy> the vfd can be blind, linuxcnc will tell it what speed and direction right?
[23:33:05] <CHNCguy> With the encoder feedback
[23:33:18] <rob_h> i have found over years running real spindle motors in openloop vector does not work too grate.. well not for our use, hoppy use would work fine i guess
[23:33:33] <rob_h> soon as slap encoder feedback on they come back tolife almost as good as a real spindle drive
[23:33:35] <CHNCguy> well the spindle does have a encoder inspide of it
[23:33:44] <CHNCguy> inside*
[23:34:11] <CHNCguy> I was reading the fanuc manual for the drive and the CHNC schematic, it has a pulsing mechanism, I assume is an encoder....
[23:34:22] <rob_h> inside motor yes
[23:34:25] -!- asdfasd has quit [Ping timeout: 252 seconds]
[23:34:27] <CHNCguy> When I mean spindle, I mean the motor
[23:34:31] <rob_h> a gear type wheel and a pickup
[23:34:37] <rob_h> but its sine and cosine output
[23:34:50] <CHNCguy> So we cant use it for my vfd?
[23:35:16] <rob_h> only if you convert it to square wave, or have a drive option that can read in sine cosine. i have not read your manual
[23:35:22] <rob_h> only look realy quick and saw what modes it did
[23:35:51] <rob_h> what size VFD did u get? motor in our CHNCs mine and johns are the 5.5kw motors
[23:36:05] <CHNCguy> i have a 7.5kw motor
[23:36:12] <CHNCguy> I got a 7.5kw vfd
[23:36:24] <rob_h> urs a CHNC 1 or 2
[23:36:27] <CHNCguy> 2
[23:36:35] <CHNCguy> II SP
[23:36:36] <rob_h> maybe they added a bigger motor for some reason then
[23:36:55] <CHNCguy> it is for sure a 7.5kw, it says it on the name plates
[23:37:06] <rob_h> sure.. so 44amp motor?
[23:37:26] <CHNCguy> not sure about the amperage, but I checked this before buying the VFD
[23:37:47] <rob_h> says on same plate 30min and const ratings
[23:37:50] <CHNCguy> I don't have it near me to check, it weighs about 200+ lbs though....just the motor, not including the plate
[23:38:11] <rob_h> i know our mills have the 7.5kw motors on them
[23:38:49] <CHNCguy> Mmm ill double check :)
[23:38:51] <rob_h> but our chnc 1 are not 1:1 gearing i found... motor does 6000rpm but spindle is only doing 5000rpm
[23:39:05] <rob_h> dont know about 2 maybe its 1:1 why a bigger motor
[23:39:36] <CHNCguy> probably
[23:39:42] <CHNCguy> how heavy is yours? :)
[23:39:56] <rob_h> so if u have not checked that yet... when u run VFD and it says its doing 4000rpm say and linuxcnc says spindle encoder is less then probly know why
[23:40:07] <rob_h> how heavy what? the motor
[23:40:14] <CHNCguy> yes, just curious
[23:40:21] <rob_h> pritty much the same id have to look in manual to see
[23:40:32] <rob_h> but 5.5kw and a 7.5kw motor is much diff in size
[23:40:33] <CHNCguy> See, I am completely retrofitting it
[23:41:08] <CHNCguy> I took the entire lathe out including motor and am mounting it on a benchtop style setup
[23:41:18] <CHNCguy> the enclosures were crap
[23:41:24] <zeeshan> what vfd aare you using btw?
[23:41:32] <rob_h> whats the model number of VFD
[23:41:54] <zeeshan> teco and eaton drives use 0-10v input as one way to control the speed
[23:42:12] <CHNCguy> its a Hyria Inverter 10hp SL series SL-275EE
[23:42:29] <zeeshan> chinese special!
[23:42:30] <zeeshan> :D
[23:42:37] <rob_h> single phase
[23:42:41] <CHNCguy> 3phase input
[23:43:12] <CHNCguy> I have many of these and they work great, just havnt used them in conjunction with a linux or cnc
[23:43:22] <zeeshan> looks very much like my eaton drive
[23:43:29] <zeeshan> guaranteed its got 0-10v control ;D
[23:43:37] <CHNCguy> It does have 0-10v control
[23:43:41] <rob_h> yea but these fanuc motors and other real spindle motors do love to be driven unlike a normal induction motor
[23:43:59] <zeeshan> usually the finned type motors like vfd
[23:44:15] <CHNCguy> If the drive cant run it good, ill get something else, no biggy ;)
[23:44:15] <zeeshan> those sheet metal ones don't
[23:44:30] <zeeshan> it should run it good
[23:44:36] <zeeshan> just hook it up in manual mode and get it running like that first
[23:44:41] <zeeshan> before trying to computer control it
[23:44:48] <rob_h> does this VFD havea heavy duty mode and normal/light mode?
[23:45:16] <zeeshan> is it sensorless vector
[23:45:24] <CHNCguy> I don't know about heavy duty or not but I know it can run 30mins at 150% its rating
[23:45:31] <CHNCguy> it is sensorless vector
[23:45:35] <zeeshan> sweet
[23:45:36] <CHNCguy> or sensed vector
[23:45:38] <zeeshan> so its so easy to setup then
[23:45:46] <CHNCguy> you can choose
[23:45:52] <zeeshan> you dont really need sensed vector for turning applications in my opinion
[23:46:08] <rob_h> depends how much cut you take ;)
[23:46:12] <CHNCguy> The setup calls for a simple auto tuning with no load and it sets all the paramaters
[23:46:19] <zeeshan> the only place from what i've read that sensed vector shines is at 0-5hz
[23:46:21] <CHNCguy> like winding current and all that
[23:46:30] <zeeshan> the sensorless vector works great at all otehr frequencies
[23:46:45] <zeeshan> yea you can't have any pulley connected to it when auto tuning
[23:46:56] -!- Einar_ has quit [Quit: Leaving]
[23:47:08] <zeeshan> after you're done autotuning, you will rarely see speed flucations
[23:47:08] <rob_h> it might alarm out on some things in auto tune too
[23:47:19] <rob_h> as fanuc motors are built very speshial for high HP high speed
[23:47:35] <zeeshan> i thought fanuc motors were servers
[23:47:36] <zeeshan> *servos
[23:47:36] <rob_h> some moan about induction readings and such due to the values
[23:47:38] <CHNCguy> I know I have to get a braking resistor....
[23:48:03] <rob_h> 1kw brake resistor should do
[23:48:12] <CHNCguy> mine are 3 phase motors
[23:48:19] <zeeshan> ah okay
[23:48:19] <CHNCguy> not dc
[23:48:34] <rob_h> he means on spindle motors more newer machines are true servo motors
[23:48:44] <rob_h> just very high speed, hight HP servo motors
[23:48:44] <zeeshan> yea cause at work we could index the spindle
[23:48:50] <CHNCguy> ohhh
[23:48:51] <zeeshan> at various positions so milling can be done
[23:48:54] <rob_h> yea u can on induction motors
[23:49:02] <rob_h> just need a realy good vector drive
[23:49:30] <rob_h> i just put a yaskawa on our mill. and that thing runs the mitsubishi motor sweet now.. orientates it nicly
[23:49:47] <zeeshan> yaskawa makes nice drives
[23:49:52] <rob_h> afew other drives i have tryed, well they cant do it very well.. yaskawa does have a spindle firmware installed tho
[23:49:54] <zeeshan> expensive though!
[23:50:12] <rob_h> well i throught it was not bad priced, 1600 including tax and encoder board
[23:50:17] <rob_h> 40amp drive
[23:50:35] <CHNCguy> hey rob are u running linux on urs? or the old control?
[23:50:39] <rob_h> every one else was around that price too
[23:50:59] <rob_h> linuxcnc on, CHNC , Superslants 2x off, leadwell VMC
[23:51:12] <rob_h> soon to be a 2nd VMC when i get time
[23:51:22] <rob_h> and a 3rd superslant with power tooling when i get time
[23:51:31] <rob_h> thats a 4 axis machine also
[23:51:56] <CHNCguy> I got a guy thats gonna give me 2 cincinatti vmcs that I can convert to linuxcnc, you think its worth the effort?
[23:52:05] <rob_h> love to change the sliding head over but that will have to stay mitsubishi for now as no way linuxcnc can handle all them axis

[23:52:34] <rob_h> but depends on the machine etc...
[23:53:05] <rob_h> if needs new ball screw bearings, are screws in good condition, how about spindle bearings.. what slides like etc etc
[23:53:16] <CHNCguy> Im still learning this linuxcnc stuff, its taking a while...
[23:53:40] <rob_h> i rember doing my firm machine the VMC lol.. took awhile yea

[23:57:17] <rob_h> for?
[23:58:25] <rob_h> CHNCguy, page 45 of manual shows u how to wire vfd, then u just need to feed a 0-10v analog from mesa card to the drive and away you go
[23:59:01] <CaptHindsight> rob_h: " to change the sliding head over"
[23:59:55] <rob_h> erm, 6 only a citizen L16 VIII , but its more having use of working with sub spindle while main is working with out putting two PCs in side and linking them
