[00:23:58] <PetefromTn_> jeez
[00:24:12] <PetefromTn_> rob_h ya still there man..
[00:24:15] <rob_h> ye
[00:24:21] <rob_h> awake just
[00:24:34] <PetefromTn_> sorry my damn laptop locked up on me never had that happen before on this machine..
[00:25:01] <PetefromTn_> Ok I made all the changes we discussed.
[00:25:14] <PetefromTn_> Now I guess it is just time to save the file and cross fingers and toes...
[00:25:31] <rob_h> your tool table will be wrong now so have to redo that as you know
[00:25:37] <PetefromTn_> sure
[00:25:59] <PetefromTn_> that is no big deal I usually touch off all my tools each time anyways in case I forget I changed something...
[00:26:10] <PetefromTn_> Okay here goes nothing..
[00:26:37] <Tom_itx> man i heard that crash clear over here
[00:27:03] <rob_h> dont worry he just forgot the vise handles again and hit the doors
[00:27:15] <PetefromTn_> OK got no errors but I tried to enable and got an immediate joint 2 following error
[00:27:49] <PetefromTn_> recommendations?
[00:27:56] <rob_h> Z axis
[00:28:00] <PetefromTn_> yeah
[00:28:12] <rob_h> check over ur ini make sure no mistakes

[00:29:26] <PetefromTn_> open it up some?
[00:30:25] <rob_h> did u try to move it / home it
[00:30:28] <rob_h> or just error
[00:30:54] <PetefromTn_> immediate joint error upon servo enable
[00:31:07] <PetefromTn_> 'just changed it to 1" and it enabled no errors now
[00:31:17] <PetefromTn_> thats probably not good heh
[00:31:26] <PetefromTn_> gonna try to home it

[00:53:23] <PetefromTn_> but it seems the movements are off
[00:54:03] <PetefromTn_> right now when I click MPG .01 in X axis it takes like four or five clicks to go .001" and it is kind of slow to react
[00:55:02] <PetefromTn_> actually it is 3 clicks

[01:43:37] <PetefromTn_> trying to get it to move the correct amount at least and wound up chaning it from the -49.something back to the 1250 which it was before

[01:48:13] <Tom_itx> beats $65 US if anyone's looking
[01:49:30] <PetefromTn_> Okay I am having issues with my damn magnetic base
[01:49:44] <PetefromTn_> now it seems to move .01 when I click it .01 on the MPG
[01:50:16] <PetefromTn_> it does seem to move very slowly tho not nearly like it normally would rapid to that position
[01:50:29] <PetefromTn_> max velocity slider is showing 315 in/min
[01:50:35] <PetefromTn_> jog speed is maxed at the same
[01:51:38] <PetefromTn_> .001" clicks seem to move it .001 on the X axis which is the only one we changed the encoder count to 31750

[02:08:08] <PetefromTn_> I have been looking over the new settings and cannot see why it would move so slowly..
[02:10:53] <XXCoder> . at wrong places?
[02:14:20] <pcw_home> looks like you divided P and FF1 instead of multiplying it by 25.4
[02:14:24] -!- syyl_ has quit [Ping timeout: 245 seconds]
[02:15:10] <PetefromTn_> Oh really
[02:15:20] <PetefromTn_> I just was kinda doing the same thing to everything..
[02:15:34] <PetefromTn_> would that quicken up the show?
[02:15:45] <pcw_home> thats fine but it needs to be multiplied, not divided
[02:15:52] <PetefromTn_> OK
[02:15:57] <PetefromTn_> the P and the ff1
[02:16:40] <pcw_home> so they are about 600 times too low now
[02:16:40] <PetefromTn_> gonna try it on the X axis only
[02:17:55] <PetefromTn_> that would make the P 228.6??
[02:18:23] <pcw_home> what was the original value
[02:18:31] <PetefromTn_> 9
[02:18:53] <pcw_home> ok so yeah thats sounds about right
[02:19:37] <PetefromTn_> and the ff1 would become .381
[02:19:57] <PetefromTn_> what sounds right the math or the actual result
[02:20:14] <rob_h> the magic number
[02:20:16] -!- ariscop has quit [Ping timeout: 265 seconds]
[02:20:38] <pcw_home> P and FF1 must be multiplied by 25.4
[02:20:44] <PetefromTn_> Ok
[02:20:53] <PetefromTn_> gonna do just the X axis and try it.
[02:21:36] <PetefromTn_> hey that seems MUCH better
[02:23:01] <pcw_home> tuning should be the same as before
[02:23:14] <PetefromTn_> just jogged X around and it seems to be working as it did before...
[02:23:19] <PetefromTn_> Thank you PCW
[02:23:31] <PetefromTn_> So I should now make the same changes on the Y and Z
[02:23:40] <pcw_home> Yep
[02:23:41] <PetefromTn_> unless you see anything that stands out to you as a problem
[02:24:02] <rob_h> yep dont forget Y had some I and D also which needs a * 25.4 also
[02:24:37] <PetefromTn_> OK thank you Rob I know you want to get to sleep you have been SO helpful tonight I really appreciate it.
[02:24:59] <rob_h> no prob what we all here for right :)
[02:25:26] <PetefromTn_> Just got X to home out...beautiful!!
[02:25:57] <PetefromTn_> OK lemme make these changes to Y and Z and see what happens hjere

[02:32:41] <PetefromTn_> OK Y axis seems to work fine now...
[02:40:06] <PetefromTn_> OK
[02:40:13] <PetefromTn_> Z axis is set and is working.
[02:40:14] <PetefromTn_> BUT
[02:40:46] <PetefromTn_> I am having a little issue where when I put a DTI on the Z against the table and move down incrementally in Z say .01 per MPG click
[02:41:03] <PetefromTn_> it moves down beyond the point and then kinda slowly creeps back up to it.
[02:41:55] <PetefromTn_> It seems to hit it but it goes beyond in the negative direction a touch maybe on a .01 move .o01 and then moves back up to the right position..
[02:42:23] -!- danylevskyi has quit [Quit: Leaving]
[02:44:47] <pcw_home> that should not be any different than before, Z may simply need better tuning
[02:44:51] <cradek> that's just servo tuning
[02:45:00] <cradek> heh yeah what he says
[02:46:03] <PetefromTn_> standby
[02:46:05] <pcw_home> Z is a little special because you dont have any counterbalance
[02:46:08] <PetefromTn_> thanks for the suggestion
[02:46:47] <PetefromTn_> trying to rig up a spindle mounted indicator so I don't have to futz with this piece of shite Chinese mag base
[02:47:45] <pcw_home> I wonder if your fancy drives can inject a constant upwards torque in that part of the velocity control loop
[02:48:57] <PetefromTn_> I would LOVE to get this Z sorted out as I have to limit my speed on it or it will fault coming down...
[02:51:04] <zeeshan> GOD
[02:51:05] <cradek> are they velocity mode with tachs?
[02:51:08] <zeeshan> THIS IS MAKING go crazy!!!!
[02:51:20] <zeeshan> VFD plz respond!!!
[02:52:10] <zeeshan> PetefromTn_: can you plot analogout2 and axis.2.ferror?
[02:52:49] <zeeshan> :01030001000102
[02:52:53] <zeeshan> im sending this message to the vFD
[02:52:56] <zeeshan> and this bastard wont reply
[02:53:01] <zeeshan> bcc code is correct
[02:53:07] <zeeshan> function code is correct, slave address is correct
[02:53:08] <zeeshan> ..
[02:53:11] <PetefromTn_> hang on man I am trying to do something here
[02:53:18] <pcw_home> Thats because you are not polite

[02:53:56] <zeeshan> they probably made it this way so you couldn't use standard modbus hardware
[02:54:05] <zeeshan> and had to buy their own propietary stuff
[02:54:13] <Tom_itx> what signal can i use to test my spindle index pulse?

[02:55:15] <zeeshan> i would really appreciate if you guys could take a look at the vfd manual under comms section, and see if im going blind. i don't see any addresses for reading registers
[02:55:28] <PetefromTn_> Okay guys
[02:55:49] <PetefromTn_> I rigged up a dial indicator in the drill chuck since my chinese mag base is a piece of dog shit
[02:55:59] <PetefromTn_> now I have a rigid reading of the movement
[02:56:41] <PetefromTn_> when I jog down it goes beyond the .01 distance about .003-.004 and then slowly goes back up to the number exactly
[02:57:06] <PetefromTn_> takes like two to three seconds to get back to the position.
[02:57:12] <PetefromTn_> never had that before..
[02:57:19] <PetefromTn_> any ideas what changed?

[02:57:53] <zeeshan> PetefromTn_: are you sure
[02:58:01] <PetefromTn_> am I sure of what?
[02:58:06] <zeeshan> that it didnt happen before
[02:58:11] <PetefromTn_> yes absolutely..
[02:58:18] <zeeshan> that sounds like a tuning issue
[02:58:25] <zeeshan> go back to your old ini and remeasure
[02:58:30] <zeeshan> and see if you have the same prob to prove it to yourself
[02:58:33] <PetefromTn_> it would have certainly fucked up parts and I have been getting great results
[02:58:47] <cradek> which of pidff did you scale?
[02:58:59] <PetefromTn_> there is a bias setting i there as well as a deadband setting I don't think we changed...
[02:59:01] -!- f1oat has quit [Ping timeout: 256 seconds]
[02:59:14] <PetefromTn_> cradek what do you mean?
[02:59:23] <PetefromTn_> we scaled the P and the ff1
[02:59:40] <cradek> I'm pretty sure you shouldn't scale ff1
[02:59:51] <cradek> I think you should scale P,I,D and not FF1 or FF2
[03:00:20] <PetefromTn_> ok why do you say that it seemed to work for the X and Y...
[03:00:36] <cradek> you don't have an indicator on them? haha
[03:00:41] <PetefromTn_> yeah I did
[03:01:00] <PetefromTn_> the movements were crisp and to the numbers like it was before.
[03:01:18] <PetefromTn_> I have been getting VERY precise movements and parts from the machine before just metric native..
[03:01:21] <Tom_itx> check for a typo just in case
[03:01:43] <pcw_home> Yeah that right FF1 should be divided
[03:01:45] <PetefromTn_> right now the P is at 228.6 and the ff1 is at .889
[03:02:06] <PetefromTn_> not multiplied?
[03:03:01] <PetefromTn_> I would have thought if I tried to rigid tap with this issue we would have broken some shit LOL...but I recently rigid tapped a shit load of holes 5/8 deep in 6061
[03:03:19] <pcw_home> No, FF1 does need to be multiplied
[03:04:41] <PetefromTn_> ff1 was at .035 and it is now at .889...
[03:05:02] <pcw_home> that is your output is scaled in volts, 10V FS, to translate say 10 IPS to 10V needs FF1 of ~1
[03:05:03] <PetefromTn_> what about the bias and the deadband
[03:05:43] <pcw_home> bias should stay the same (since its in volts)
[03:05:44] <PetefromTn_> so do you think it is off?
[03:06:02] <pcw_home> I think you should plot it
[03:06:09] <PetefromTn_> OK how..
[03:06:55] <pcw_home> HalScope
[03:07:07] <PetefromTn_> I'm saving the .ini file as it is currently and reopening linuxCNC
[03:07:46] <PetefromTn_> Okay

[03:08:16] <PetefromTn_> I know jack squat about using halscope
[03:08:58] <PetefromTn_> what do I have to do to plot the Z axis..

[03:16:00] <zeeshan> echo -e "blahjasdlkadsjlkasdjsdaklsadlkjsadljkasd" >> /dev/ttyS0
[03:16:32] <zeeshan> does b for example get translated to binary?

[03:16:42] <zeeshan> so b = 96 in decimal
[03:16:48] <zeeshan> so it would 62 H ?
[03:17:45] <PetefromTn_> what signals do I want and how do I select them
[03:18:38] <pcw_home> look at zeeshan's pic
[03:18:46] <PetefromTn_> I am
[03:18:52] <PetefromTn_> got some of it setup that way
[03:19:38] <PetefromTn_> right now I have red on 1 and green on 2 4000 samples at 1.0khz normal run mode normal trigger but I have 500m/div and I cannot get the level to his numbers
[03:19:39] <Tom_itx> PetefromTn_ i think you select them from the lower right button in the box
[03:19:50] <Tom_itx> after you select a channel
[03:19:51] <pcw_home> you select pins,signals, and params with the channel buttons on the bottom
[03:19:53] <zeeshan> PetefromTn_: your level will be diff
[03:20:17] <zeeshan> the way i do it is after i have the pins setup, i quickly press force and within like 1 sec jog the axis.
[03:20:27] <zeeshan> then i increase the gain on the analog out
[03:20:40] <zeeshan> then i move the trigger threshold on the rising edge of the analog out
[03:20:49] <zeeshan> then you can do another jog
[03:20:51] <PetefromTn_> I hit the right bottom button and it says trigger source
[03:20:56] <PetefromTn_> chan and source
[03:21:00] <zeeshan> after that increase gain on the f-error. im not sure if thats the correct way to do it
[03:21:02] <zeeshan> but it works for me
[03:21:04] <PetefromTn_> how do I select the sorce
[03:21:25] <zeeshan> source chan should be whatever analogout is set to.

[03:23:46] <PetefromTn_> what?
[03:24:02] <zeeshan> those arent the right pins!
[03:24:05] <PetefromTn_> I don't know how to use it..
[03:24:17] <PetefromTn_> COnnor helped me with it before and he did the plotting
[03:24:23] <zeeshan> its okay
[03:24:27] <zeeshan> halscope is confusing
[03:24:30] <PetefromTn_> yeah I know they are not the right pins how do I select them
[03:24:33] <zeeshan> click where it says selected channel
[03:24:43] <zeeshan> click on the button
[03:24:47] <PetefromTn_> OK
[03:24:52] <zeeshan> on your screen the button that says hm_2blsahdasjklasdasdk
[03:25:09] <zeeshan> i wasn't laughing at you not working it
[03:25:14] <Tom_itx> you must have the russian translation up
[03:25:15] <PetefromTn_> ok I see the signals now which ones do we want
[03:25:16] <zeeshan> i was laughing at the signal
[03:25:40] <zeeshan> PetefromTn_: !! see my image!
[03:25:44] <PetefromTn_> I guess axis out for axis 2 and f error
[03:25:58] <zeeshan> axis.2.-f-error
[03:26:09] <zeeshan> hm2_5i25.0.7i77.0.1.analogout1
[03:26:13] <zeeshan> hm2_5i25.0.7i77.0.1.analogout2
[03:26:14] <zeeshan> i mean
[03:26:45] <zeeshan> okay
[03:26:53] <zeeshan> i have a hammer in my hand right now
[03:27:05] <zeeshan> if this vfd doesnt reply to my manual code
[03:27:12] <zeeshan> its going to meet a brutal death
[03:27:34] <PetefromTn_> OK I have number one set for that 5i25 analog out 2 and number 2 set for axis 2 f error
[03:30:01] <PetefromTn_> http://i.imgur.com/huR27K4.jpg
[03:31:16] <PetefromTn_> ok is that right?
[03:31:44] <zeeshan> on the button that says source chan 3
[03:31:53] <zeeshan> click it and change it to channel 1.
[03:32:42] <PetefromTn_> OK
[03:33:26] <PetefromTn_> done
[03:34:36] <PetefromTn_> the machine won't jog with the halscope up gotta minimize it is that normal?
[03:35:13] <PetefromTn_> should I set it to auto trigger?
[03:35:56] <zeeshan> nah
[03:36:23] <zeeshan> [22:20:18] <zeeshan> the way i do it is after i have the pins setup, i quickly press force and within like 1 sec jog the axis. [22:20:28] <zeeshan> then i increase the gain on the analog out [22:20:42] <zeeshan> then i move the trigger threshold on the rising edge of the analog out [22:20:51] <zeeshan> then you can do another jog 22:21:02] <zeeshan> after that increase gain on the f-error.
[03:37:35] <PetefromTn_> I thought we were just trying to get a plot
[03:38:15] <Tom_itx> do the first two steps for that
[03:39:17] <PetefromTn_> Ok
[03:39:20] <PetefromTn_> did that..
[03:39:34] <PetefromTn_> got something not sure what or if it is correct..
[03:39:46] <Tom_itx> alt-prntscr and paste
[03:39:50] <PetefromTn_> I jogged the axis up a half inch or so..
[03:40:00] <PetefromTn_> can't machine is not online
[03:40:11] <PetefromTn_> gotta take photo and load on other puter
[03:40:19] <Tom_itx> well thars yer problem!
[03:40:51] <PetefromTn_> yup there's one of em at least LOL
[03:42:11] <PetefromTn_> http://i.imgur.com/lPnd8Rb.jpg
[03:44:24] <PetefromTn_> can you guys see that OK
[03:46:39] <pcw_home> looks like FF1 is way off
[03:46:53] <PetefromTn_> OK
[03:47:27] <PetefromTn_> right now it is at .889
[03:47:36] <PetefromTn_> what would you recommend?
[03:48:37] <zeeshan> holy shit
[03:48:37] <zeeshan> ahha
[03:49:23] <zeeshan> dont mind me
[03:49:26] <pcw_home> I cant tell without directions but try 1/2 that and twice that and chose the better
[03:49:27] <zeeshan> im losing my mind here over this vfd
[03:50:14] <PetefromTn_> OK stupid question but do you have to close and reopen linuxCNC each time you make a change?
[03:50:33] <pcw_home> are you using the calibrate pane?
[03:50:55] <PetefromTn_> not sure what that is..
[03:51:16] <PetefromTn_> just repoened linuxCNC after saving changes to .ini
[03:51:19] BitEvil is now known as SpeedEvil
[03:51:36] <pcw_home> thats the hard way...
[03:51:59] <PetefromTn_> of course it is...LOL
[03:52:15] <pcw_home> in axis chose menu item machine--> calibration
[03:52:56] <PetefromTn_> OK
[03:53:17] <PetefromTn_> I can also open the halscope again right
[03:53:17] <pcw_home> select the tune2 tab
[03:53:52] <PetefromTn_> OK nice the halscope settings did not change
[03:54:15] <PetefromTn_> the tune 2 tab shows my ff1 change
[03:54:20] <PetefromTn_> it is now .445
[03:54:24] <PetefromTn_> from .889
[03:54:35] <PetefromTn_> .4445 rather
[03:55:23] <PetefromTn_> Ok just took another sample..
[03:55:28] <PetefromTn_> stdby for photo
[03:56:22] <pcw_home> you need to click test to commit the change
[03:56:24] <pcw_home> (and save to file to commit to file)
[03:56:57] <PetefromTn_> http://i.imgur.com/TwIkNv5.jpg
[03:57:09] <PetefromTn_> OK
[03:57:49] <PetefromTn_> is that worse or better?
[03:58:46] <PetefromTn_> Looks like the F error went up instead of down this time and the amplitude was higher somewhat...
[03:58:48] -!- gimps has quit [Read error: Connection reset by peer]
[03:59:01] <pcw_home> so .7?
[03:59:18] <PetefromTn_> .7 is what you want me to set it to?
[03:59:37] -!- gimps [gimps!~noone@unaffiliated/gimps] has joined #linuxcnc
[03:59:47] <pcw_home> well .889 was too much, .44 was too little ...
[04:00:10] <PetefromTn_> OK so I made it .7 now I hit test do I need to save to file too
[04:01:34] <bobo_> pete hope these test jog's are all in same direction
[04:01:43] <PetefromTn_> yes they are all UP..
[04:02:06] <PetefromTn_> should I do them in the negative direction becasue that is where the problem really lies due to the weight of the head?
[04:02:09] <zeeshan> i dont understand why your tuning got messed for z only?
[04:02:20] <PetefromTn_> neither do I.
[04:02:29] <zeeshan> thats quite a bit off..
[04:02:37] <zeeshan> 6 thou
[04:02:41] <PetefromTn_> but to be honest I really don't understand what I am doing here too well anyways..
[04:02:44] <zeeshan> i mean 3 thou
[04:03:03] <zeeshan> PetefromTn_: im really curious for you to change your ini to your backup
[04:03:11] <zeeshan> and replotting this same thing.
[04:03:18] <PetefromTn_> why?
[04:03:30] <zeeshan> because if the error doesnt exist in your original ini
[04:03:36] <zeeshan> there was something that happened during the conversion
[04:03:36] <PetefromTn_> I want this to be imperial and it is ALMOST there now.
[04:03:46] <zeeshan> you just changed your ini right?
[04:03:58] <PetefromTn_> just gotta retune one axis which honestly probably was not right in the first place..
[04:04:02] <PetefromTn_> yeah
[04:04:11] <zeeshan> how hard is it to copy that ini rename it
[04:04:14] <PetefromTn_> I was getting errors when the head rapid down in the Z
[04:04:16] <zeeshan> and put in your old one?
[04:04:22] <zeeshan> okay
[04:04:25] <zeeshan> then your tuning was off to begin with
[04:04:36] <PetefromTn_> not really sure what was off.
[04:04:39] <pcw_home> how does .7 for FF1 look?
[04:04:42] <zeeshan> its off by 3 thou
[04:04:59] <PetefromTn_> pcw_home Standby workign on it...
[04:05:19] <zeeshan> pcw_home why is his signal so blotchy
[04:05:20] <zeeshan> like its got steps
[04:05:31] <zeeshan> encoder resolution?
[04:06:41] <PetefromTn_> http://i.imgur.com/Gly6IJQ.jpg
[04:07:33] <pcw_home> .6 ?
[04:07:40] <PetefromTn_> is there any tweaking I can do to the halscope to get the view better>
[04:08:03] <PetefromTn_> perhaps the P needs to be adjusted too?
[04:08:39] <pcw_home> yeah lower the gain on ferror so it doesn't go off scale
[04:09:08] <PetefromTn_> OK
[04:09:37] <pcw_home> then you can see if you reducing the ferror as you are dialing in FF1
[04:09:50] -!- sumpfralle has quit [Quit: Leaving.]
[04:10:29] <PetefromTn_> Ok I just went to change to .6 and I am not sure if the .7 change took effect.
[04:10:43] <Tom_itx> you gotta restart
[04:10:48] -!- scooty_puff has quit [Ping timeout: 245 seconds]
[04:10:53] <Tom_itx> so it re reads the file
[04:11:04] <pcw_home> click test and refresh
[04:11:07] <skunkworks> love thos screenshots..
[04:11:08] <skunkworks> :)
[04:11:12] <Tom_itx> unless you can make changes in halscope
[04:11:15] <PetefromTn_> when I hit test the windows grey out...
[04:11:19] <Tom_itx> skunkworks :)
[04:11:50] <Tom_itx> nearly got mine rewired and ready to try
[04:11:57] <Tom_itx> new bit files etc look ok
[04:12:06] <pcw_home> type new data in, press test, the press refresh
[04:12:20] <pcw_home> then press refresh
[04:12:39] <PetefromTn_> OK
[04:13:28] <PetefromTn_> http://i.imgur.com/DM8naiE.jpg
[04:14:11] <pcw_home> calibrate is a little awkward that way (but a lot less awkward than restarting linuxcnc each time)
[04:15:14] <PetefromTn_> just tried the MPG with the Dial indicator it seems to have tightened up a touch but it still slowly comes back up to the number goes beyond it by about .002 now..
[04:15:31] <pcw_home> hmm looks like P gain is too low (no correction at all)
[04:15:49] <PetefromTn_> Ok
[04:15:56] <PetefromTn_> where do I change that...
[04:16:06] <pcw_home> calibrate
[04:16:11] <PetefromTn_> just P
[04:16:17] <PetefromTn_> in calibrate
[04:16:47] <pcw_home> what other calibrate items are non zero?
[04:17:35] <pcw_home> if you have ant deadband, set it to 0
[04:17:39] <pcw_home> any
[04:17:40] <PetefromTn_> bias is .021 deadband is .0016 outputs are all 10 and -10 and encoder scale is 31750
[04:17:47] -!- bilboquet_ has quit [Remote host closed the connection]
[04:17:52] <pcw_home> set deadband to 0
[04:18:06] <PetefromTn_> Ok
[04:18:36] <pcw_home> it should behave better
[04:19:03] <pcw_home> .0016 mm is ok .0016 inches is too big...
[04:19:22] <PetefromTn_> OK
[04:19:59] <pcw_home> that explain some crazyness in the plots
[04:20:05] <pcw_home> explains
[04:20:12] <PetefromTn_> http://i.imgur.com/V4IwOQP.jpg
[04:21:17] <pcw_home> a lot better, now you need to dial in ff1 so the ferror that mirrors the velocity goes away
[04:22:08] <PetefromTn_> what do you suggest?
[04:22:46] <PetefromTn_> I am not entirely sure what this plot SHOULD look like here '
[04:23:01] <pcw_home> ferror should be 0
[04:23:14] <PetefromTn_> do we want the F error to overlay the command?
[04:23:17] <PetefromTn_> Oh Ok
[04:23:22] <pcw_home> no
[04:23:26] <PetefromTn_> so it is dipping down and should be level
[04:23:33] <pcw_home> yes
[04:23:43] <PetefromTn_> ok lets try .5?
[04:24:30] <PetefromTn_> Ok that was closer to the level line but still dips down a bit
[04:26:10] <PetefromTn_> .4 was much better...
[04:26:58] <PetefromTn_> http://i.imgur.com/alCRM6W.jpg
[04:27:36] <bobo_> O neat
[04:28:40] <PetefromTn_> just did the MPG .01 movement against the Dial indicator atop my kurt vise.. .01 moves it .01 and it no longer dips down like it was..
[04:29:08] <PetefromTn_> is there anything in that plot that could be improved upon? Can I change the parameters of the halscope to get a better view to fine tune it?
[04:30:02] <pcw_home> a tiny bit of ff2 can fix the slight errors during accel/decel
[04:30:21] <PetefromTn_> how tiny...
[04:30:42] <PetefromTn_> .001 .01 .1?
[04:30:47] <pcw_home> I always have to guess at FF2 maybe .001
[04:30:52] <PetefromTn_> OK
[04:30:56] <PetefromTn_> lemme try that..
[04:31:43] <pcw_home> see how the error is a tiny bit above the line on accel and below on deccel?
[04:31:57] -!- AR_ has quit [Ping timeout: 256 seconds]
[04:32:05] <PetefromTn_> yes
[04:32:18] <PetefromTn_> changed the zoom at the top
[04:32:19] <pcw_home> thats the part FF2 tweaks
[04:32:27] <PetefromTn_> ran it again.
[04:32:29] <PetefromTn_> stby
[04:32:33] <bobo_> hope you can show halscope of a up also having down jog on same trace ----befor you finish up

[04:34:00] <PetefromTn_> I will try to bobo
[04:34:11] <PetefromTn_> right now it is looking MUCH better.
[04:34:36] <PetefromTn_> I may just screw around with the X and Y again to ensure it works as well as possible but the Z has been kind of a bitch since I started with this machine.
[04:34:56] <PetefromTn_> no counterweight and a heavy ass millhead is a prescription for pain LOL
[04:34:59] <pcw_home> well now you know how to tune your servos :-)
[04:35:05] <PetefromTn_> nice
[04:35:08] <Tom_itx> heh
[04:35:15] <PetefromTn_> what do you think of that last scan
[04:35:15] <Tom_itx> hope you wrote it all down
[04:35:38] <PetefromTn_> haven't had time with all the head scratching hehe
[04:35:48] <pcw_home> looks pretty decent
[04:35:56] <PetefromTn_> would you add some more ff2?
[04:36:13] <pcw_home> I'd do the same for X,Y and Z down
[04:36:31] <PetefromTn_> Yeah Z down is a good idea...
[04:36:41] <PetefromTn_> lemme try one with Z down
[04:36:42] <pcw_home> no its looks about as good as you can get
[04:38:06] <pcw_home> you might try bumping P up a bit to see if you can get away with any more gain (with a finger over F1 in case ist starts oscillating badly)
[04:38:25] <PetefromTn_> http://i.imgur.com/mktKAla.jpg
[04:38:51] <pcw_home> looks good
[04:38:56] <PetefromTn_> OK in what kind of increments?
[04:39:02] <PetefromTn_> right now at 228.6
[04:39:09] -!- skorasaurus has quit [Ping timeout: 272 seconds]
[04:39:18] <pcw_home> try 300 maybe
[04:39:24] <PetefromTn_> OK
[04:41:22] <bobo_> Z down (to me ) shows more braking at end of jog
[04:42:44] <PetefromTn_> http://i.imgur.com/lB7vskr.jpg Okay that is a short down jog at about 80 IPM with P set to 300
[04:43:44] <PetefromTn_> it looks like the F error goes a touch above flat there for some reason..

[04:45:46] <PetefromTn_> the encoder count is freakin' spot on... .1 in .01 increments moves the dial EXACTLY to the zero again all around the face one time..I was pretty sure we had it this way before but I still had the faults under rapid down movemnents
[04:46:25] <pcw_home> that does look like your 230 or so is close to the limit (you can see some oscillation when its starts the decel)
[04:47:10] <PetefromTn_> what do you mean 230?
[04:47:32] <pcw_home> well it was 228.6
[04:47:50] <PetefromTn_> ok so I need to back it down some then?
[04:48:13] <pcw_home> looks like it, maybe 250
[04:48:20] <PetefromTn_> OK lemme try that.

[04:51:09] <PetefromTn_> I really appreciate the help.
[04:51:36] <PetefromTn_> I will play with this tuning of the Z and hopefully with any luck I will have better rapid speeds without faulting..

[04:53:16] <bobo_> greedy huh
[04:53:32] <PetefromTn_> you see how when it stops at the end it kinda floats back...that is what my machine was doing before only with WAY more error and a lot slower response
[04:54:16] <skunkworks> it was floating back about .00005 ;)
[04:55:23] <PetefromTn_> yeah I know pretty tight man impressive.
[04:55:46] <skunkworks> chris got it even better when he stopped by.. amazing.
[04:56:20] <PetefromTn_> you guys are all amazing.

[06:24:18] * PetefromTn_ hehe Awesome... Deleting all my metric freakin' Tool length offsets while laughing maniacally
[06:25:42] <bobo_> great and great
[06:26:28] <bobo_> pull stud and inch tool table
[06:27:56] <zeeshan> haha
[06:29:39] <PetefromTn_> man that is just awesome
[06:29:49] <PetefromTn_> I can't thank you guys enough for all the help
[06:30:32] <PetefromTn_> now all I have to do is figure out how to output a good cutter compensation code from my CAM and I can start using the machine the way it was meant to be used
[06:31:27] <PetefromTn_> I think I STILL need to do some tweaking of my servo tuning for all three axes and I want to experiment a bit more with that
[06:31:36] <PetefromTn_> but it seems to be working as before now
[06:32:08] <PetefromTn_> I may have actually learned something here today about how the damn thing works too.
[06:33:08] <bobo_> pete have you looked at X an Y with halscope ?
[06:33:38] <PetefromTn_> hopefully with what I learned today I can help Brendan get his machine working as well he will probably be able to use my metric setup
[06:33:43] <PetefromTn_> yeah briefly
[06:34:04] <PetefromTn_> the X was not as good as the Z was once I got it sorted still needs some tweaking
[06:34:10] <PetefromTn_> the Y was not bad
[06:34:31] <PetefromTn_> like I said I think I need to spend another couple hours working with it trying to tweak it to be the best it can be.
[06:35:24] <PetefromTn_> I have been measuring tool length offsets from the G59.3 position atop the 123 block
[06:35:57] <PetefromTn_> I typically use the top of Z travel for G59.3 Z0 and then pickup the tool length offsets from that position
[06:36:27] -!- ariscop has quit [Ping timeout: 265 seconds]
[06:36:40] <bobo_> on X try pushingtable when it's moving . see if disterbance shows up on hal scope
[06:36:42] <PetefromTn_> but I am wondering if it should be that the tool length offsets are measured from machine coordinates somehow that way they are based on the homing setup
[06:36:57] <PetefromTn_> I will try that tomorrow.
[06:37:12] <PetefromTn_> Right now I am tired and gonna sit here and chat and watch Star trek LOL
[06:37:58] <PetefromTn_> is it possible to measure the TLO's from machine coordinates somehow?
[06:38:24] <PetefromTn_> like I said the horizontal position is at the right rear corner of the tables travel
[06:38:35] <PetefromTn_> G59.3 G0 X0 Y0
[06:38:36] <bobo_> so where is brendan? working the sheep dip operation?
[06:38:55] <PetefromTn_> dunno he said he was actually going to be here tonight trying to get his machine going.

[06:39:14] <zeeshan> can someone open that second link?
[06:39:40] <PetefromTn_> not opening for me for some reason
[06:39:45] <zeeshan> same here..
[06:39:49] <zeeshan> they have the studs for order there
[06:39:51] <zeeshan> fak.
[06:40:25] <PetefromTn_> my Cinci uses a longish stud kinda like the HAAS machines
[06:41:18] <PetefromTn_> once I get the cutter compensation sorted and working the next goal is spindle orient then finally toolchanger!!
[06:45:42] <bobo_> I can't get that link to open or www esve either

[06:54:11] <bobo_> pete i thought ridgid tapping had to have spindle orentation ?
[06:54:40] <PetefromTn_> it does
[06:54:45] <PetefromTn_> well sort of
[06:55:02] <PetefromTn_> it uses the index pulse to locate and start the movement
[06:55:16] <PetefromTn_> my machine did rigid tap perfectly
[06:55:35] <PetefromTn_> but I have not tested it since just changing this over to imperial native units here tonight.
[06:55:55] <bobo_> oh just not tied into tool change?
[06:55:58] <PetefromTn_> I forgot to check the spindle settings which were not changed
[06:56:18] <PetefromTn_> well I have not actually tried to orient the spindle yet not really sure how.
[06:56:50] <PetefromTn_> Now that the metric conversion to imperial is done I will make sure everything is still working here some more tomorrow and do some more fine tuning.
[06:57:07] <bobo_> wish I knew
[06:57:21] <PetefromTn_> once I am back to making accurate parts and whatnot I will be looking next to get on the spindle orientation setup
[06:57:55] <PetefromTn_> the rest of the toolchanger stuff is already implemented and tested. All of the motors and switches and pneumatic already are proven to work.

[12:10:34] <unfy> just starting to
[12:10:37] <Bushman> do it! do it now!!!
[12:10:50] <unfy> those cheap chinese linear bearings or ?
[12:10:58] <Bushman> yup
[12:10:58] <unfy> i'm curious what folks think of the chinese ones etc
[12:11:04] <Bushman> or i think they are

[12:11:56] <Bushman> i can't complain... the two axis i've made with them are decent... the one made with drawer slides is now getting disassembled :P

[12:12:31] <unfy> the chinese slides will prolly be next go around
[12:12:36] <Bushman> sure, you try that!
[12:12:58] <Bushman> right after you decide it's pain in the ass buy those cheap stuff
[12:13:21] <Bushman> i don't know if mine are chinese or not but i'm sure happy with them
[12:15:39] <Bushman> i'm opgrading the last axis so i can start milling thicked aluminum... then i'll be upgrading the chassis
[12:16:32] <unfy> http://imgur.com/gsWLjo3,TLYzuoO,80OwCJQ#2
[12:16:39] <Bushman> but now i'm starting to see i didn't think all this through..
[12:17:12] <Bushman> i should have used the machine to make new lead screw mounting points for those new rails and bearings are lower profile
[12:17:24] <unfy> well for short axis stuff, the chinese linear stuff is prolly fine. for big heavy stuff, i dunno
[12:17:26] <Bushman> oh well... back to hacksaw XD
[12:17:29] <unfy> :D
[12:17:52] <unfy> and yeah, using the machine to make replacement parts is something i keep reminding myself to do for later
[12:17:58] <unfy> to not get too excited etc :)
[12:18:10] <Bushman> i'm using 16mm rods for 600mm (500mm travel)
[12:18:39] <Bushman> i have 600, 500 and 400mm rods now
[12:18:54] <Bushman> X, Y and Z respectively
[12:19:03] <unfy> \o/
[12:19:22] <Bushman> tho right now Y and X are gonna be temporarly swapped
[12:19:40] <Bushman> cause 600 are in Y right now and i've just got the 500mm ones this morning
[12:19:45] <unfy> i almost wanna keep the bag closed ... just to keep that new kit smell :3
[12:20:00] <Bushman> lol
[12:20:41] <Bushman> punch holes for cables and seal with duct tape LOL

[12:22:45] * unfy reads the quick start guide
[12:23:40] <Bushman> yea
[12:23:48] <Bushman> i want one myself
[12:23:58] <Bushman> but so far have no justification to get it
[12:24:37] <unfy> i do my own pcb's and stuff... and after 15 years of doing embedded work and all that - i got f'in tired of not having a scope heh
[12:27:37] <Bushman> well, my dad has a scope next room so i just use his
[12:27:39] <Bushman> :P
[12:28:30] <Bushman> but it would be awesom to have one of those lightweight portable ones that i can tuck in to a shelft or fetch it for a quick fix job at the clients place

[12:30:06] <Bushman> new one on the bottom
[12:30:25] <Bushman> rigid one in the background and flexible (rubber hose) one on top
[12:30:26] <unfy> i nearly grabbed a 140/200m sample usb based scope
[12:31:12] <unfy> heheheh ... i skipped the hose or drilling my own couplers and just bought 10 off ebay ...
[12:34:14] <Bushman> the rubber one had some slipp first but i've tightened it down and it works like a charm...
[12:34:57] <Bushman> the rigid one was hell to position properly and transferred all the noise from the motor to the table working like resonance box lol
[12:36:34] <unfy> the rigid one being unforgiving is one of the reasons i decided against making my own - and the rubber version i just had a feeling that i'd find a way to !@*#%( it up
[12:36:38] <unfy> so grads :D
[12:36:42] <unfy> er grats :D
[12:37:48] <Bushman> the rubber ones was tricky... you need the tightest fit hose you can get and smallest band claps

[18:23:32] <PetefromTn_> so I tried again today
[18:23:41] <PetefromTn_> and finally got someone to call me back
[18:24:08] <PetefromTn_> he seemed familiar with the machine and knew the control manufacturer which is anilam
[18:24:29] <PetefromTn_> and he is apparently going to try to get me the information on the original spindle motor.
[18:24:49] <PetefromTn_> we will see if he actually gets back to me but he seemed like he would.
[18:25:36] <zeeshan> you need to know the motor frame specs?
[18:25:57] <PetefromTn_> yeah it would be nice to know the type of motor that it came with.

[18:32:38] <zeeshan> PetefromTn_: a friend of mine offered me 3500 for my cnc lathe
[18:32:50] * zeeshan is wondering if i can find a slant bed!
[18:32:51] <PetefromTn_> that would be a cheap price..
[18:32:55] <zeeshan> lathes arent cheap up here
[18:32:57] <zeeshan> cnc
[18:33:08] <zeeshan> i hate my lathe because of the tool changer
[18:33:19] <zeeshan> the cross slide will never be big enough to hold enough tools
[18:33:41] <zeeshan> and having two live spindles
[18:33:45] <zeeshan> REALLY makes a hell of a differenc on a lathe
[18:34:15] <PetefromTn_> Oh hell yeah live tooling is a BIG deal but usually the realm of very large and expensive machinery
[18:34:18] <zeeshan> http://www.rohnermachinery.com/photos/0700_3.jpg
[18:34:22] <zeeshan> this is absolutely SEX
[18:34:41] <malcom2073> I wish I had a lathe
[18:34:50] <malcom2073> I'm not actually entirley sure why
[18:35:02] <zeeshan> yea PetefromTn_
[18:35:04] <zeeshan> im not gonna sell this
[18:35:09] <malcom2073> Other than I have an urge to see that machine in action... to the youtube!
[18:35:09] <zeeshan> unless i find something much much better
[18:35:10] <PetefromTn_> I would love to have a nice big slant bed but honestly for what I do this flatbed will be perfect...
[18:35:10] <zeeshan> this works well
[18:35:19] <zeeshan> it just takes longer
[18:35:24] <zeeshan> i hate flipping a part in the lathe
[18:35:28] <zeeshan> reindicating it
[18:35:33] <zeeshan> i need to buy more collets.
[18:35:48] <PetefromTn_> do you have a collet closer on it?
[18:35:52] <zeeshan> no
[18:35:59] <zeeshan> i shoulda written
[18:36:01] <zeeshan> i need a collet chuck!
[18:36:02] <PetefromTn_> that is a big deal for small parts
[18:36:13] <PetefromTn_> no you don't want a collet chuck
[18:36:13] <malcom2073> So, a lathe like that can turn one side, grab the turned side then turn the other, yeah? Is there any equivalant to that on a mill?
[18:36:18] <PetefromTn_> you want a pneumatic closer...
[18:36:45] <PetefromTn_> that way you can maybe even bar feed small round stock
[18:36:59] <zeeshan> i forgot the spindle bore on this thing
[18:37:03] <zeeshan> 1-7/8?
[18:37:15] <PetefromTn_> wow that is bigger than mine was
[18:37:26] <zeeshan> Spindle bore: 1 7/16"
[18:37:32] <zeeshan> off by half an inch
[18:37:32] <PetefromTn_> I think mine was like 1.5 or something
[18:37:32] <zeeshan> haha
[18:37:42] <zeeshan> 1.4375
[18:37:55] <zeeshan> you had the exact same lathe as me
[18:38:11] <PetefromTn_> yeah they are all basically the same in that size
[18:38:16] <PetefromTn_> good little machine
[18:38:19] <zeeshan> yes!
[18:38:32] <zeeshan> im happy that it can do .5" doc in 6061
[18:38:37] <zeeshan> i just dont like the manual intervention
[18:38:47] <zeeshan> of having to reindicate parts
[18:38:52] <zeeshan> most of the parts ive been making are two sided

[18:40:51] <PetefromTn_> even with my hamfisted quick setup on that little 5c collet closer I machined those standoffs and rigid tapped them and faced them to length within .002 or so and I was not even trying to be real consistent on length
[18:41:16] * zeeshan needs one!
[18:42:12] <PetefromTn_> this is all just cheap stuff. The collet stop is from shars and it is actually pretty decent unlike some of the stuff I got from them..
[18:42:37] <PetefromTn_> I plan to make or buy a nice collet closer for the Standard Modern lathe.
[18:43:01] <zeeshan> PetefromTn_: where did you get your cat40 stuff from?
[18:43:05] <zeeshan> i was looking at the shars.
[18:43:09] <zeeshan> they claim 1 tenths tir
[18:43:19] <zeeshan> i don't know whether to believe that or not.
[18:43:26] <PetefromTn_> honestly while I would love a nice big sub spindle live tooled CNC slant bed that is just not in the cards right now unless I want to buy a real old beat up one..
[18:43:29] <zeeshan> i was planning to get glacern cat40 tool holders, but guess what? they'r;e made in taiwan.
[18:43:47] <PetefromTn_> yeah they are all bascially made in china now even the good ones...
[18:43:48] <zeeshan> so if theyre going to be from taiwan
[18:44:01] <zeeshan> might as well get shars!
[18:44:03] <PetefromTn_> I got mine from that niucume guy CME tools...
[18:44:05] <zeeshan> maritools makes them in usa.
[18:44:13] <PetefromTn_> do they?
[18:44:18] <zeeshan> yes theyre about 105$
[18:44:24] <PetefromTn_> I heard different ideas about that
[18:44:31] <PetefromTn_> would not doubt it.
[18:44:35] <zeeshan> the fact theyre made in usa doesn't mean anything
[18:44:36] <PetefromTn_> They make QUALITY stuff
[18:44:47] <zeeshan> ive seen some real shit stuff made in usa too
[18:44:51] <PetefromTn_> I have been very pleased with everything I have purchased from them
[18:45:10] <zeeshan> well ill try them out
[18:45:16] <zeeshan> i was thinking when i order my pull studs from mari
[18:45:19] <PetefromTn_> my toolholders are low priced chinese made but so far have not been a problem and I make some nice parts with them
[18:45:21] <zeeshan> order 1 of their tool holders and collet
[18:45:28] <zeeshan> and order the shars 5 pack deal w/ 5 collets
[18:45:30] <zeeshan> and compare them
[18:45:41] <zeeshan> if theyre the same
[18:45:45] <zeeshan> im grabbing shars :P
[18:45:50] <PetefromTn_> I hear good things about the shars ones..
[18:46:00] <zeeshan> really? thats good to know
[18:46:00] <PetefromTn_> the last shop I worked in had a bunch of them
[18:46:06] <zeeshan> i tried to search online for reviews
[18:46:09] <PetefromTn_> never really noticed any problems..
[18:46:13] <zeeshan> and for some goddamn reason, peoplpe don't review them
[18:46:20] <zeeshan> they just get into made in usa made in china arguement, every single damn time
[18:46:21] <zeeshan> so annoying
[18:46:35] <PetefromTn_> I bought what I could afford.
[18:46:42] <PetefromTn_> and I have been more than pleased so far
[18:46:46] <zeeshan> weell their moto is you can always afford more
[18:46:49] <zeeshan> if you save up long enough haha
[18:46:58] <zeeshan> my moto is
[18:47:05] <zeeshan> if a certain country can make it cheaper and better. buy from them.
[18:47:11] <zeeshan> you focus on what you're good at
[18:47:16] <PetefromTn_> I will probably buy more of these ER20 holders in a five pack from CME tools here at some point.
[18:47:31] <PetefromTn_> I find them very useful.
[18:47:40] <PetefromTn_> I use the ER32 for the bigger bits
[18:48:00] <PetefromTn_> but the small ones can get into tighter places easier without worrying about clamps and hitting things.

[18:55:20] <PetefromTn_> it is machined from3/4 6061 barstock
[18:55:28] <zeeshan> can you not just set the tool in the machine?
[18:55:40] <zeeshan> or are you talking about when you need to tighten the pull stud
[18:55:54] <PetefromTn_> yeah loading tools and pullstuds in the holders on the bench

[19:00:27] <zeeshan> ooo thats sexy
[19:00:30] <zeeshan> pete i have a dumb quesiton for you
[19:00:47] <zeeshan> to machine a part like that with a fancy outer contour like that
[19:01:08] <zeeshan> you cant obviously hold it in a vise cause otherwise you're machining the vise too
[19:01:15] <rob_h> hi peter u got it all working fine now then
[19:01:17] <zeeshan> do you bolt it down to a fixture plate that your vise holds?
[19:01:32] <PetefromTn_> rob_h YEAH MAN!! THANK YOU THANK YOU THANK YOU!!
[19:01:52] <rob_h> grate
[19:02:07] <cradek> zeeshan: you just roll your eyes and stop the program after it's done with the important internal features
[19:02:13] <PetefromTn_> zeeshan well depends. that part I actually drilled and tapped those holes into a sacrificial plate and then drilled the part while clamped down using strap clamps.
[19:02:28] <zeeshan> cradek: haha
[19:02:34] <PetefromTn_> then I bolted it down to the substrate
[19:02:40] <PetefromTn_> and machined the rest of the features
[19:03:14] <PetefromTn_> if you had thicker stock what I normally try to do is hold onto like .1" or .2" in the vise and machine the whole part down to the depth
[19:03:33] <PetefromTn_> then flip the whole thing over and face off the bottom flashing leaving just the part
[19:03:41] <zeeshan> ah
[19:03:57] <PetefromTn_> I only had 3/4 stock so I had to bolt it down
[19:04:10] <rob_h> you get to make alot of chips fast too when you face mill ;)
[19:04:18] <PetefromTn_> hell yeah man
[19:04:29] <zeeshan> .1" deep psssht!
[19:04:32] <zeeshan> only one pass
[19:04:33] <zeeshan> !
[19:04:34] <PetefromTn_> a good facemill makes TONS of chips..
[19:04:42] <PetefromTn_> two actually
[19:04:51] <PetefromTn_> one rough and one to make it pretty ;)
[19:04:55] <zeeshan> haha
[19:05:02] <zeeshan> dude some of those sexy face mills
[19:05:10] <zeeshan> the finish they leave during roughing in my opinion is sexy!
[19:05:24] <PetefromTn_> I NEED to invest in a quality facemill..
[19:05:31] <PetefromTn_> probably a 3" model
[19:05:41] <PetefromTn_> maybe a seco
[19:05:44] <rob_h> 50/60mm facemill does 90% of stuff i find
[19:05:50] <zeeshan> i have a mitsu
[19:06:11] <zeeshan> its okay.. but istill thing with this type of face mill
[19:06:17] <zeeshan> you really need to sit down and ensure all the inserts are at the same level
[19:06:23] <zeeshan> on like a granite table or something
[19:06:37] <zeeshan> *think
[19:06:51] <PetefromTn_> does it just have clamps and not pockets that make it fit precisely?
[19:07:19] <jdh> how close are different batches of inserts?
[19:07:35] <rob_h> from the same make pritty dam good
[19:07:37] <jdh> when you wear one side and rotate, does it still nest the same?
[19:07:46] <zeeshan> PetefromTn_: it holds them pretty accurately
[19:07:49] <PetefromTn_> if it is a good quality one it does..
[19:07:52] <zeeshan> but the inserts vary by a couple tenths
[19:07:53] <rob_h> they do say tho if using other insert makes you should use there screw also..
[19:08:02] <rob_h> turning u find that more so
[19:08:49] <PetefromTn_> it is also a good idea to invest in one of those ratchet torx torque screwdrivers for the inserts screws.
[19:09:24] <PetefromTn_> those little screws are a bitch and easy to bugger up.
[19:09:53] <rob_h> use the SEK 45deg aproach alot as uses not much power and is posative cutting
[19:10:07] <rob_h> then use the APKTs for sholder milling alot

[19:10:24] <PetefromTn_> rob_h now that I have the imperial measurements in the native system on the machine I can start playing with cutter compensation with my programs...
[19:10:36] <jdh> Pete: got it all converted?
[19:10:40] <PetefromTn_> yeah
[19:10:42] <PetefromTn_> last night
[19:10:42] <jdh> cool
[19:10:50] <PetefromTn_> thanks to Rob and PCW and Zeehsan
[19:10:56] <PetefromTn_> zeeshan
[19:11:06] <zeeshan> :D
[19:11:13] <PetefromTn_> next challenge is SPINDLE ORIENT!!!!
[19:11:17] <rob_h> yea we only use cutter comp here now days for tweaking sizes... when programed mostly online yea we programed real numbers then put comp on
[19:11:51] <PetefromTn_> yeah basically in the shops I worked in here it is INTEGRAL to use cutter comp for making accurate parts...
[19:12:15] <PetefromTn_> they program to the size and then offset the cutter comp and then make adjustments on the machine to creep up on critical dimensions..
[19:12:38] <jdh> you do that after CAMing the part to nominal?
[19:13:31] <PetefromTn_> like I said we program the CAM to the actual part dimension.. then if it is critical dimension we change the diameter of the cutter at the machine to cut short and then adjust cutter diameter again to creep up on the dimension
[19:14:07] <rob_h> can use comp as a offset adjustment if you like , or you can use it for the cutter size in use.. so if you can cutter just change comp.. plus can tweak with it.. its main two ways you can use it at least
[19:14:13] <PetefromTn_> if it is a couple tenths tol we do this but if it is like .005 or so just run it..
[19:14:52] <jdh> adjust cutter comp. So you go through the CAM'ed code and add the G41/G42?
[19:14:54] <PetefromTn_> yeah it allows you to run a part with a different sized cutter than programmed too if you tweak it.. never done that much but it is an option.
[19:15:21] <PetefromTn_> no just adjust the tool table
[19:16:04] <jdh> so G41/G42 are already in the CAMed code?
[19:16:27] <rob_h> ye
[19:16:34] <rob_h> most cams u can ask comp on or off
[19:16:48] <PetefromTn_> rob_h I am curious, do you generally leave the tool table diameters at zero and make your adjustments in whatever small increments you need or do you make the tool table diameter the size of the tool and adjust that number?
[19:17:04] <PetefromTn_> jdh yeah it will be once I get it setup right.
[19:17:37] <rob_h> we use it as a trimmer so zero all the time, then if we need to tweak we adjust the D number in the TBL by the ammount
[19:17:42] <roycroft> i have a bunch of 120 degree spot drills arriving today with my tooling order
[19:17:52] <roycroft> no more center drills for starting holes in my mill
[19:17:56] <rob_h> its how we use it on all our machines fanuc or what ever.. then after the job just clear them all
[19:18:21] <PetefromTn_> ok so you do not input the actual diameters just leave them all zero and adjust only the change you need.
[19:18:22] <PetefromTn_> nice
[19:18:41] <PetefromTn_> roycroft excellent man that is how it is done... center drills are for lathes man LOL
[19:18:49] <roycroft> it's odd
[19:18:56] <roycroft> i was taught to use center drills in the mill
[19:19:08] <roycroft> and my instructor was pretty meticulous
[19:19:16] <roycroft> but it was a college shop program
[19:19:17] <rob_h> just been drilling holes today in pre hard tool steel, Carbide drills no C/Drill stright in :)
[19:19:25] <roycroft> they probably didn't have the budget for both
[19:19:43] <roycroft> i've never used spot drills before, but i anticipate good results
[19:19:46] <PetefromTn_> yeah man carbide drills can kick ass and they even sometimes recommend you do not spot drill depending on the grind.
[19:19:46] <jdh> you don't spot with carbide bits do you?
[19:19:52] <roycroft> sometimes with a center drill the twist drill will grab a little at first
[19:19:57] <roycroft> i expect that problem to go away
[19:20:07] <jdh> wrong angle from a center drill
[19:20:10] <roycroft> yup
[19:20:23] <roycroft> and the spot drills are 2 degrees wider than the twist drills
[19:20:29] <roycroft> so they should work brilliantly
[19:20:40] <jdh> I use the remaining good side of my center drills, if there is one.
[19:21:22] <rob_h> bk later
[19:21:29] <PetefromTn_> cya
[19:21:36] <PetefromTn_> thanks again man
[19:22:01] <jdh> I think I have destroyed all my small ones.
[19:22:29] <roycroft> it sucks getting old - my eyes are really shot
[19:22:41] <roycroft> i have a bunch of 4-40 blind holes to drill and tap
[19:22:48] <roycroft> i did some a couple days ago
[19:23:06] <roycroft> but last night, on the first one, i grabbed a bottom tap instead of a starter tap because i couldn't see the difference
[19:23:11] <roycroft> and of course it broke off

[19:23:58] <PetefromTn_> sucks to break a tap
[19:24:05] <PetefromTn_> 4-40 is a bitch
[19:24:06] <roycroft> it does, which is why i rarely do so
[19:24:09] <roycroft> i know how much it sucks
[19:24:12] <jdh> my sacrificial plate I use has a couple of broken taps stuck in it.
[19:24:15] <roycroft> yes, i'm probably going to just remake the part
[19:24:21] <roycroft> which will take about 3 hours
[19:24:34] <roycroft> but a 4-40 in a blind hole i might never get out
[19:24:37] <jdh> what material?
[19:24:42] <roycroft> mild steel
[19:24:57] <jdh> edm it out
[19:25:06] <roycroft> sure, if i had anedm
[19:25:19] <roycroft> i've been meaning to make one, but so far i haven't
[19:25:20] <jdh> just think, if you had one, you could break taps all teh time.
[19:25:34] <PetefromTn_> I always thought a broken tap was a death sentence for the part but working in the shops locally they usually program a .0005 peck drilling op with a carbide drill after grinding a flat on top
[19:25:57] <PetefromTn_> it goes right thru em
[19:26:03] <PetefromTn_> even a 4-40
[19:26:05] <roycroft> sure
[19:26:15] <roycroft> if it's not difficult to grind a flat on top
[19:26:21] <PetefromTn_> its getting the little bits out that is a bitch
[19:26:22] <roycroft> and if you have no spindle runout
[19:26:52] <roycroft> it broke off below the surface, making the grinding the flat thing a little problematic
[19:26:54] <PetefromTn_> I have seen them do it even when they could not reach the top and grind
[19:27:15] <roycroft> the broken tap is on a corner of the part
[19:27:16] <PetefromTn_> they usually start with a carbide endmill center cutting
[19:27:30] <roycroft> i might cut it out, weld a piece of 1/4" steel in, and mill it back down
[19:27:34] <roycroft> that would take less than 3 hours
[19:27:50] <PetefromTn_> if it is steel we would usually cut it out and tig weld it back together..

[19:28:38] <roycroft> the piece that has the blind hole in it is 0.220 thick, so a piece of 1/4" would be fine
[19:28:42] <roycroft> 0.220"
[19:28:51] <PetefromTn_> it depends on the part, the material, and the amount of time it will take to remedy it as well as how much time has already been invested in the part.
[19:29:08] <roycroft> ~3 hours to remake the part
[19:29:27] <roycroft> i know i can patch a piece of steel in in less time than that
[19:29:55] <jdh> drill it oversize and plug it?
[19:30:06] <SpeedEvil> jb-weld
[19:30:10] <roycroft> well there's not much room to drill it oversize
[19:30:14] <cradek> unless it's stuck in steel, rust it out with alum
[19:30:19] <roycroft> because i'm drilling into the end of the piece
[19:30:20] <cradek> we just talked about this recently :-)
[19:30:22] <jdh> it's stuck in steel
[19:30:25] <cradek> arg
[19:30:41] <roycroft> which is 0.220" thick
[19:32:47] <roycroft> that was the start of last night
[19:33:04] <roycroft> i decided to just put that part aside and drill/tap the rest of them, and come back to it today
[19:33:15] <roycroft> when i get frustrated i don't work as well
[19:33:44] <roycroft> so i've learned to not deal with problems like that right away
[19:34:08] <roycroft> but i have that today, and soldering some ss to mild steel, which i've never done
[19:34:12] <roycroft> it should be an interesting afternoon
[19:34:44] <roycroft> my past attempts at soldering ss have not gone well
[19:35:02] <roycroft> but this time will be great!
[19:36:49] * roycroft compensates for his lack of skill and experience with a positive attitude
[19:37:03] <PetefromTn_> jeez man
[19:37:15] <PetefromTn_> I just heard back from the folks at Standard MOdern
[19:37:34] <PetefromTn_> apparently that spindle motor was made by Custom SErvo Motors inc and was a 3 speed motor.
[19:37:44] <PetefromTn_> they gave me the model number
[19:37:47] <PetefromTn_> I googled it...
[19:37:50] <PetefromTn_> NOTHING came up.
[19:39:15] <PetefromTn_> Oh well I guess I am on my own with this one..
[19:39:56] <rob_h> why you have an EDM is it not for broken taps only
[19:40:26] <PetefromTn_> LOL
[19:41:23] <roycroft> it can be used when you want to do random milling without purchasing any tooling
[19:41:53] <rob_h> o like them long deep narrow slots in this mold tool we are doing right now ;)
[19:42:39] <PetefromTn_> rob_h how many linuxCNC machines do you guys have there?
[19:43:18] <rob_h> not enougth is the answer right
[19:43:29] <PetefromTn_> heh
[19:44:05] <rob_h> 1 VMC currently, 3 Lathes, 2x Multi turret hardinge, 1x CHNC2 hardinge
[19:44:30] <rob_h> wondering wether to convert one of the other VMCs at moment now
[19:44:58] <rob_h> there is a 4 axis lathe with power tooling waiting for my TLC
[19:45:24] <PetefromTn_> wow
[19:45:27] <PetefromTn_> nice
[19:45:30] <rob_h> i did think about converting our big Dean Smith and grace lathe which has a philips right now
[19:45:52] <PetefromTn_> BRB
[19:45:54] <rob_h> 500mm chuck, gearbox etc so you can take some nice cuts on that and remove steel no problem
[19:45:57] <PetefromTn_> gotta pickup my kids

[21:00:06] <PetefromTn_> and they both still fell off..
[21:00:17] <PetefromTn_> is there a secret sauce?
[21:01:45] <SpeedEvil> what materials?
[21:01:55] <PetefromTn_> ?
[21:02:29] <jdh> mirror and plastic?
[21:02:33] <skunkworks> glass and steel I would guess.
[21:02:55] <PetefromTn_> no it is that little tombstone shaped piece of metal and the windshield glass..
[21:03:02] <jdh> heh, good luck with that.
[21:03:05] <CaptHindsight> both surfaces have to be really clean

[21:05:59] <PetefromTn_> just bought this permatex kit hopefully will have better luck this time.
[21:06:10] <PetefromTn_> last one was made by loctite
[21:06:21] <CaptHindsight> you need to use epoxies at high enough temps
[21:06:22] <PetefromTn_> one before was O'reilleys auto parts brand
[21:06:44] <CaptHindsight> if they get too cold they won't polymerize well
[21:06:44] <PetefromTn_> maybe I need to just drill a damn hole and screw it on lol
[21:06:58] <CaptHindsight> 70F or warmer
[21:14:17] <PetefromTn_> well then it will be awhile before I have a rearview mirror then hehe
[21:16:34] <CaptHindsight> PetefromTn_: did the adhesive stick more to the glass or to the metal?
[21:17:26] <PetefromTn_> dunno really. it is supposed to only be one drop on the metal and you press and hold it to the glass..

[23:45:24] <Tom_itx> PetefromTn_, i just used a kit from the auto store and never had any problems
[23:45:40] <Tom_itx> don't scratch the glass first
[23:45:49] <Tom_itx> clean it with acetone or something like that
[23:48:54] <PetefromTn_> yeah man already did that twice now and cleaned the shit out of it... still freakin fell off.
[23:53:05] <PetefromTn_> we'll see how this permatex stuff works now I guess..
