[00:12:48] <FinboySlick> I don't get it. I got my centre drill, did a couple test holes. I'm still exactly the same measure off. I've got to be measuring it wrong.

[00:14:55] <tjb1> You need to change that depending on what you do

[00:31:28] <tjb1> linux-cnc-bob: Did that fix it?
[00:31:45] <FinboySlick> Assuming that there isn't any black magic in my indicator, how would I test if my spindle is somehow crooked? Indicate on a known-straight rod, root to tip on both axis?

[01:21:47] <Connor> jdh: Belt Drive conversion done. (Except bearing upgrade, which I'll do this weekend hopefully.
[01:22:36] <Connor> jdh: Looks like I might have a bit of a wobble.. The pulleys might not be Bored perfectly centered.. hard to tell.. Going to take some video tonight and post it up.
[01:28:13] <jdh> did you rebore them or they came that way?

[01:53:00] <FinboySlick> Wow... I kept assuming that I was just inexperienced and measuring wrong but the axis of my spindle really isn't perpendicular to my table!
[01:53:15] <FinboySlick> Now I'm really bummed out.
[01:53:23] <FinboySlick> There are no visible adjustments for this.
[01:53:48] <jdh> what is it?
[01:54:13] <FinboySlick> jdh: What do you mean? The mill?
[01:54:19] <jdh> right
[01:54:29] <jdh> you have a mill that is un-tram-able?
[01:55:11] <FinboySlick> I'm hoping not but I'm not seeing anything obvious...
[01:55:28] <jdh> what mill?
[01:55:37] <FinboySlick> Syil X5 Speedmaster.
[01:55:41] -!- ve7it has quit [Remote host closed the connection]
[01:55:45] <jdh> wow
[01:56:12] <FinboySlick> I guess I could kind of shim the spindle motor.
[01:56:27] <jdh> it should be adjustable
[01:56:49] <FinboySlick> I guess so. I'm pealing through the manual now to at least see what part goes where.
[01:57:15] <jdh> for that much $$ it should come with detailed tram instructions
[01:59:46] <Connor> jdh Rebore them. Had too..
[01:59:58] <jdh> with a boring bar?
[02:00:03] <Connor> yes.
[02:00:09] <Connor> video coming in just a second.
[02:00:40] <jdh> guess if you just chuck them, you make the bore concentric to the outside?
[02:04:09] -!- sumpfralle has quit [Read error: Operation timed out]
[02:04:25] <Connor> correct. Video's up on my thread.

[02:05:02] <jdh> I was just reading the grease saga
[02:05:34] <ReadError> is cutting cf pretty similar to g10 ?
[02:05:36] <ReadError> speed wise
[02:05:42] <ReadError> ive never cut it before
[02:05:45] <ReadError> but got a sheet
[02:05:52] <jdh> me either
[02:06:21] <FinboySlick> jdh: It has an assembly diagram... And short of shimming, no visible adjustments.
[02:06:45] <jdh> Fin: is the head moveable at all?
[02:06:51] <FinboySlick> jdh: Now the problem is that I don't know if it's the column itself that isn't perpendicular or just the spindle.
[02:07:04] <jdh> google for mill tramming
[02:07:15] <FinboySlick> jdh: It's on four linear bearing rails.
[02:07:23] <FinboySlick> I mean two rails, four bearings.
[02:07:43] <jdh> don't screw with teh rails :)
[02:08:05] <FinboySlick> No, obviously. There are four bolts to hold the column to the base.
[02:08:14] <FinboySlick> So I can shim that.
[02:08:28] <FinboySlick> But that's a real bitch to adjust.
[02:10:08] <FinboySlick> The spindle looks like it's held by magic.
[02:10:25] <FinboySlick> No screws, no bolts, for all I know they press-fitted it in.
[02:10:32] <jdh> Connor: looks fine to me?
[02:10:52] <jdh> set screws?
[02:11:34] <FinboySlick> jdh: Doesn't look like it.
[02:11:52] <FinboySlick> jdh: I still have to figure out if it's the column or the spindle that isn't straight.
[02:12:16] -!- morfic has quit [Ping timeout: 246 seconds]
[02:12:17] <jdh> there is a way to find out, but I don't recall how.
[02:13:29] -!- morfic [morfic!~morfic@unaffiliated/morfic] has joined #linuxcnc
[02:15:44] <Tom_itx> i think if you put an indicator in the spindle and check both sides of Y and both sides of Y it will tell you if it's straight
[02:15:59] <Tom_itx> i think if you put an indicator in the spindle and check both sides of X and both sides of Y it will tell you if it's straight
[02:16:04] <Tom_itx> try that again...
[02:16:05] <FinboySlick> Tom_itx: With a square on the table?
[02:16:26] <Tom_itx> you don't need a square, use the dial indicator against the table
[02:16:37] <Tom_itx> more accurate
[02:16:45] <Tom_itx> provided the table is level
[02:17:40] <FinboySlick> Tom_itx: That tells me the spindle axis isn't perpendicular to the table. But that doesn't tell me whether it's the spindle axis that's not perpendicular to Z or Z that isn't perpendicular to the table.
[02:18:16] <jdh> there are detailed instuctions for that somewhere.
[02:18:17] <Tom_itx> then put a straight, long dowel in the spindle and see if it's square with the table
[02:18:23] <jdh> but, dunno how you move yours.
[02:18:37] <FinboySlick> That second to last 'perpendicular' was supposed to be 'parallel'
[02:18:43] <jdh> square the column to the bed, then the spindle to the column
[02:18:59] <Tom_itx> yeah
[02:19:09] <jdh> or the other way aroudn.
[02:19:10] <Tom_itx> the more accurate the measuring tool the more accurate it will be
[02:19:42] <FinboySlick> That's fine and dandy with adjustments. I have to shim that bastard.
[02:19:52] <jdh> http://www.cnczone.com/forums/benchtop_machines/121011-rollies_dads_method_rdm_mill.html
[02:20:05] <jdh> I'd contact the mfg and see if they have tramming docs
[02:20:27] <FinboySlick> That'll be fun...
[02:20:32] <Tom_itx> if you don't follow the right procedure you won't get it right and i can't remember which you wanna do first
[02:20:33] <jdh> en englese por favor
[02:20:44] <FinboySlick> I'll take french too.
[02:21:01] <ReadError> mmmm i love the smell of 3-in-1 oil
[02:21:22] <FinboySlick> ReadError: You can be beaten to death for using that ;)
[02:21:29] <FinboySlick> (Boardwalk Empire)
[02:21:40] <ReadError> oh BWE is good stuff
[02:21:53] <ReadError> im using it for cutting
[02:22:03] <ReadError> it actually works very well on this aluminum tube
[02:22:09] <ReadError> i was melting it before
[02:22:16] <ReadError> now i rub a little on, like butta
[02:22:52] <r00t4rd3d> wtf
[02:23:41] -!- factor has quit [Ping timeout: 244 seconds]
[02:24:20] <Tom_itx> FinboySlick, if you run the table back and forth with the dial in the spindle, you can verify the table is flat
[02:24:25] <Tom_itx> in X and Y
[02:24:48] <ReadError> ScribbleJ, you around?

[02:30:07] <FinboySlick> The column would be with a straight pin, no?
[02:30:57] <Tom_itx> ?
[02:32:14] <ReadError> ok nsfw joke kinda
[02:32:15] <ReadError> "The gf told me to go out and get some of those pills that will help me get an erection. You should have seen her face when i came back and gave her some diet pills."
[02:32:49] <Tom_itx> lookin for a new gf now?
[02:32:56] <ReadError> lol
[02:43:42] * FinboySlick looks at the inspection sheet from the factory: Chen is a liar.
[02:45:28] -!- broofa has quit [Quit: Computer has gone to sleep.]
[02:45:59] <Tom_itx> but you found out after you paid him
[02:46:02] <Tom_itx> all is good
[02:47:00] <FinboySlick> I don't think Chen got to see much of that money.
[02:47:11] <ReadError> whats a good decent sized mill for 3-4k ?
[02:47:19] <ReadError> i want to step up in awesome
[02:47:27] <jdh> BP
[02:47:32] <ReadError> something new
[02:47:34] <ReadError> not all old and rusty
[02:47:42] <ReadError> that will require a bunch of work
[02:47:48] <jdh> you would get a lot more for used than for new.
[02:47:49] <ReadError> i want to fit the electronics and have at it
[02:47:53] <Connor> jdh: Yea. set screws.. You look at it closely.. You can see the run nout ..
[02:48:04] <ReadError> plus i dont have a forklift to move it
[02:48:05] <jdh> connor: I saw it, but...
[02:48:06] -!- archivist_herron has quit [Ping timeout: 264 seconds]
[02:48:18] <jdh> is the runout in line with the setscrews?
[02:48:32] <Connor> but, the set screws shouldn't effect the runnout.. it's seated against the top of the spindle in a pocket.
[02:48:58] <jdh> the pulley is?
[02:49:03] <Connor> yea.
[02:49:12] <jdh> didn't know they did that.
[02:49:20] <Connor> They don't.
[02:49:47] <jdh> heh. errr... ok.
[02:49:58] <Connor> It has a slighty large bore to set onto of the spindle.. kinda like the RPM disk does..

[02:50:24] <jdh> if the bore is larger, then the setscrew would push it off to one side?
[02:50:33] <Connor> Press fit.
[02:51:03] <Connor> I guess I could open it up a little and adjust it.
[02:51:28] <jdh> did you indicate the ID of the pulley when you chucked it to bore it?
[02:51:57] <Connor> No. :)
[02:52:02] <jdh> I don't know what you would reference with it already bored
[02:52:03] <Connor> Only have a 3 jaw..
[02:52:33] <jdh> it didn't look that bad in the video
[02:52:44] <Connor> Yea.. That's the issue.. It's a casting.. I just bored it out.. Maybe I need to open the pocket up a bit.
[02:53:05] <Connor> let me go out and messure it.. brb
[02:53:17] <jdh> is that the new motor or one of the stock ones?
[02:53:42] <jdh> I'm gone... boat leaves at 6am.

[11:07:22] <Anon2133> Hello, I've just set up a CNC lathe to use a stepper motor to power the spindle. I've edited the .hal file so that I can run the motor, which is controlled via step/dir, using the normal spindle commands however I can't work out how to use it with threading. It appears that I need to put the encoder settings in the .hal file, however clearly I don't have an encoder. Perhaps the step input could be divided by the number of steps per r
[11:10:29] <rob_h> you do need an encoder of sorts on the spindle to thread, as u need a mark pulse once every spindle revolution ie, to denote start of thread position, as well an A & B chanel

[17:22:16] <Tom_itx> i think i changed the res on one of the switches though. my steppers didn't like the coarse one so i cut it down a bit
[17:27:08] <JT-Shop> I'm also getting this error when I jog with the mpg which seems odd http://imagebin.org/229423
[17:27:56] <Tom_itx> that looks like one for andy or pcw
[17:28:50] <Tom_itx> are you using sserial?
[17:29:52] <pcw_home> 7I77.0.0 is the isolated I/O Power issue?
[17:30:07] <pcw_home> or 5V power maybe
[17:31:40] <JT-Shop> too much draw on the 5v?
[17:31:48] <pcw_home> Maybe
[17:32:08] <JT-Shop> it only happens when I spin the MPG
[17:32:40] <pcw_home> I would suspect the 5V
[17:33:57] <pcw_home> once you have a 7I77 loaded with encoders its likely better to not use the cable power (its only good for about an amp)
[17:34:18] <JT-Shop> ok
[17:34:30] * JT-Shop ponders where to get more 5v from
[17:35:26] <pcw_home> a serial break error is a give-away (that means the serial line was in the wrong state for at least a character time)
[17:38:05] <pcw_home> (Unless you have a misconnect and something on the jogwheel is shorting 5V)
[17:39:08] <JT-Shop> let me double check the connections and it could be a problem with the coil cord from the encoder to the electrical cabinet as I had issues before with loosing the MPG
[17:40:53] <JT-Shop> would that also affect how the axis moves when you click the MPG one click. It thumps instead of moving smoothly
[17:42:50] <pcw_home> Maybe (when things are working you can measure the 5V at TB1 so make sure its OK)

[17:59:36] <JT-Shop> I'll drag the scope out later and check with it
[18:00:44] <pcw_home> I think the 5V is more likely (since 4.6 is marginal anyway) and the 24V would have to drop out for a pretty long time for the regulator to drop below 3.3V on the isolated side

[19:03:07] <FinboySlick> L84Supper: Yeah. Buildroot sort of makes it all pretty automated though. I was quite pleased after using it for another project. Porting linuxcnc to it is definitely on my todo list.
[19:05:24] <L84Supper> FinboySlick, it's a way to learn, if you take it apart you'll see how to just write your own tools
[19:06:58] <L84Supper> FinboySlick, he just builds right for Gentoo now, we tried several projects/distros over the past 6 years or so
[19:07:51] <FinboySlick> L84Supper: It's my day to day distro so I might poke at him for hints sometimes.

[19:32:25] <JT-Shop> seem to have a brain teaser with my MPG atm
[19:36:16] <jp_> Wrong Vel mode on the MPG
[19:37:28] <JT-Shop> on the endoder?
[19:37:30] <JT-Shop> yea
[19:40:29] <JT-Shop> don't see anything for the encoder
[19:42:03] <jp_> I thought there was an INI param for MPG stuff

[19:44:31] <kirk_wallace> Hello. OT,but what software is used to put lines and text over a webcam view in AXIS?
[19:44:38] <jp_> sorry Hal axis.jog-vel-mode
[19:46:31] <JT-Shop> I tried velocity mode
[19:46:53] <JT-Shop> kirk_wallace: there is plenty of chatter on the forum about webcams and cross hairs
[19:49:15] <jp_> JT-Shop, Come to think of it why would you expect jog-speed to effect MPG
[19:49:59] <kirk_wallace> JT-Shop: Thanks, I just thought someone might know off hand. I'm trying to put a Couder mask over an Xwatv view of my mirror.
[19:50:43] <JT-Shop> jp_: I ran out of good ideas
[19:52:17] <jp_> Most machines i have worked on and my kit as well. MPG is independent of jog speed as far as i've noticed
[19:53:56] <jp_> Just don't whip that little sucker around so fast LOL
[19:55:06] <JT-Shop> it slams with one click
[19:55:21] <jp_> Whoa
[19:55:39] <JT-Shop> or bangs or thumps... moves real fast for each click
[19:55:43] <jp_> Is it moving as per the setting
[19:55:55] <jp_> ie .001 or .010
[19:56:10] <JT-Shop> yes, if I have it on 0.001 each click moves 0.001
[19:56:41] <jp_> and its banging?
[19:59:11] <JT-Shop> yea
[19:59:41] <kirk_wallace> I haven't read the history of this conversation, but "and it's banging" reminds me of when I put an MPG on my mill and I banged while MPG jogging. It turned out to be the software and an upgrade fixed it.
[20:00:20] <jp_> JT-Shop, Want fresh eyes on you HAL?
[20:01:34] <Tom_itx> JT-Shop you figure out how to get the MPG to use the jog speed lemme know :)
[20:01:47] <Tom_itx> right now it's set in the hal file
[20:05:11] <JT-Shop> the hal file http://pastebin.com/w6b1t26H
[20:05:54] <L84Supper> anyone ever use SolidCAM? How does it compare to MasterCAM that I use?
[20:06:11] <Tom_itx> haven't heard of that one
[20:06:25] <L84Supper> http://www.solidcam.com/
[20:06:55] <Tom_itx> surfcam mastercam smartcam are a few i've heard of
[20:07:00] * FinboySlick uses HSMWorks
[20:07:16] <Tom_itx> and ncpolaris which is an acad addin
[20:07:20] <FinboySlick> (it's a solidworks addon, like solidcam)
[20:08:07] <Tom_itx> if you like solidworks then you should love it
[20:08:20] <Tom_itx> i know nothing about it
[20:08:38] <Tom_itx> do they have a working demo?
[20:08:39] <L84Supper> FinboySlick, you like Solidworks? I'm probably fastest on it for more simple parts
[20:09:06] <Tom_itx> i think JT-Shop should write a how to on it
[20:09:08] <Tom_itx> :)
[20:09:24] <FinboySlick> L84Supper: Yeah, and pretty handy with it too. I'm not really good at the CAM bits though so HSMWorks is very good for me.
[20:09:39] <jp_> JT-Shop, Is there a counter mode on the mesa
[20:09:46] <Tom_itx> how do you punch a vertical hole thru a surface?
[20:10:32] <L84Supper> FinboySlick, I'm getting better with NX and I tried ProE but never became proficient
[20:10:53] <JT-Shop> jp_: let me look
[20:10:57] <Tom_itx> any of em take a while
[20:11:10] <Tom_itx> you still gotta figure out fixtures and how to cut the parts
[20:13:25] <JT-Shop> jp_: yes the 5i25 has a counter mode
[20:13:43] <jp_> whats the encoder counter mode set to?
[20:14:47] <Tom_itx> JT-Shop do you find the 5i25 harder to work with than the 7i43?
[20:16:39] <jp_> I would think it would be better
[20:16:50] <jp_> I find it much better
[20:17:03] <jp_> Wiring for sure

[20:21:14] <FinboySlick> I was asking earlier, but since more people are awake...
[20:22:12] <FinboySlick> Any advice on a good setup measure and adjust perpendicularity on column? I'll be shimming and this thing is heavy as heck so I'd rather not have too many trial and error.
[20:23:39] <JT-Shop> Tom_itx: I have no way of knowing, I don't have a 7i43

[20:30:21] <FinboySlick> JT-Shop: My problem is that if I just adjust the head so that it's perpendicular to the table but the column isn't straight, I'm still going to be off.

[20:38:27] <JT-Shop> rotating head like a BP?
[20:39:22] <FinboySlick> JT-Shop: No, all I have is shimming :P I'll have to straighten the column first, then tram to see if the spindle is misaligned.
[20:39:46] <jp_> JT-Shop, What happens when you do a .001 mdi move?
[20:40:18] <JT-Shop> dunno let me try
[20:40:26] <JT-Shop> a G0 move?
[20:40:45] <jp_> G0 or G1 and try at different F's
[20:41:25] <JT-Shop> G0 is smooth
[20:42:00] <jp_> What encoder are you using for the MPG
[20:42:02] <JT-Shop> it's as if the MPG moves are ignoring the acceleration
[20:42:19] <JT-Shop> a typical one like you find on machines
