[01:27:15] <Loetmichel> mornin'
[01:31:20] <Loetmichel> sooo. yesterday it was tooo late for milling... (neighbors)... so i called my boss " i will be late, but will have the casing done then"... *generating gcode, sawing 1,5mm aluminium sheets to a loose fit*
[03:12:04] <DJ9DJ> moin
[04:26:06] <Loetmichel> *grrr* I want a bigger mill... thats a PITA to reclamp and align every part 4 times... :-(
[05:13:17] <r00t4rd3d> anyone use Aspire?
[05:49:49] <jdh> too pricey for me.
[05:56:07] <r00t4rd3d> wanna borrow my ship?
[05:56:15] <Loetmichel> soo, re at the company... $me has it exaggerated wiht the screws... again... http://www.cyrom.org/palbum/main.php?g2_itemId=13543 :-)
[05:57:03] <jdh> I think 10 would have been more than enough.
[05:57:04] <Thetawaves> what is that?
[05:57:17] <andypugh> Countersunk look tidier.
[05:57:20] <jdh> a lot of screws that seem to require power
[05:57:21] <archivist> too many screws error at box one
[05:58:20] <Loetmichel> The_Ball: a shielding/casing for a dell notebook psu
[05:58:21] <archivist> Loetmichel, a bit of conducting joint could have been simpler
[05:58:36] <Loetmichel> grrrr Thetawaves was meant
[05:58:45] <Loetmichel> archivist: true, but costly ;-)
[05:59:33] <r00t4rd3d> http://i.imgur.com/REZnC.jpg
[05:59:49] <r00t4rd3d> basket weave :D
[06:00:05] <jdh> with a v-bit?
[06:00:19] <andypugh> The alternative is to glue on split-peas and spray paint it silver.
[06:00:27] <r00t4rd3d> jdh, yeah
[06:00:40] <jdh> looks like that would take a while.
[06:00:41] <r00t4rd3d> all modeled and tool pathed in aspire
[06:01:34] <jdh> all for only $2,000
[06:10:08] <archivist> andypugh, that library is open scourge!, I would probably doitmyself too :)
[06:19:41] <andypugh> I don't need a general solution, so it's easier to just code it as I need it.
[06:20:08] <andypugh> But it is useful to know that there isn't an easy way.
[08:26:49] <Nabster> hii
[08:28:10] <micges> hi
[08:28:48] <Nabster> whats new\
[08:29:04] <Nabster> micges
[08:29:57] <Nabster> do u know somthing about bt 5 installation
[08:31:55] <micges> back track 5?
[08:33:38] <Nabster> yea
[08:33:49] <Nabster> cause
[08:33:56] <Nabster> i tried
[08:34:27] <micges> nope
[08:34:45] <Nabster> to specify partition to install it there but its need to resize my hd
[08:35:08] <micges> maybe try on bt5 irc channel?
[08:35:43] <Nabster> give it to me
[08:41:52] <micges> I wonder if he even knew on what channel he was
[08:46:25] <archivist> or even what planet
[08:47:47] <micges> yeah
[10:32:39] <tjb1> http://www.youtube.com/watch?feature=player_embedded&v=-fDM9Eb16Do
[10:46:42] <jdh> you have waaaaaay too much free time.

[11:04:08] <tjb1> Thats not me jdh...
[11:04:45] <tjb1> the day I go to paint my table it rains >:(
[11:05:06] <jdh> you found it, and watched it, and pasted it... way too much time :)
[11:05:56] <tjb1> Im a college student ;)
[11:08:40] <jdh> shouldn't you be out gettign hot coeds drunk and in bed?
[11:34:01] <archivist> wishful thinking jdh !
[11:37:09] <tjb1> its noon
[11:37:16] <tjb1> its sunny, time to paint this thing…cya
[12:07:20] <IchGuckLive> HI all
[12:08:27] <c60> beep
[12:11:12] * JT-Shop does not fall for that and wanders off for a nap
[12:11:46] <cncbasher> jt yep the oldies need a nap
[12:16:06] <archivist> Im still awake! and hungry
[12:21:59] <IchGuckLive> darkness faling in germany
[12:22:16] <IchGuckLive> but the beerfest it true to open tomorrow
[12:54:03] <skunkworks> we have octoberfest here
[12:54:23] <skunkworks> (lacrosse had a large german population)
[13:09:44] <skunkworks> or should I say Oktoberfest
[13:10:39] <IchGuckLive> B)
[13:10:44] <IchGuckLive> =.=
[13:10:48] <IchGuckLive> O.O
[13:11:19] <archivist> cheap machine level on fleabay 200819659807
[13:11:45] <archivist> I already have one :)
[13:28:45] <IchGuckLive> by im off
[14:01:26] <archivist> it seems hard to find a price AND a specification for corrosion protection fluids
[14:18:08] <davef> Hi, How can I get rid of the axis.ngc file that automatically loads on startup of axis and/or set my own default file please?
[14:20:28] <micges> davef: http://linuxcnc.org/docs/html/config/ini_config.html#sub:[DISPLAY]-section
[14:20:45] <micges> look for OPEN_FILE
[14:21:48] <davef> OPEN_FILE = /full/path/to/file.ngc
[14:22:12] <davef> micges: THANKS! Dont know how I missed that!
[14:23:10] <davef> Bye
[16:12:28] <DJ9DJ> gn8
[17:00:52] <tjb1> 6 cans of primer and 4 cans of paint and still not done...
[17:21:03] <Jymmm> I just got a RC power meter (http://www.hobbyking.com/hobbyking/store/__10080__Turnigy_130A_Watt_Meter_and_Power_Analyzer.html) and I want to add some shrink tube to each side to at-a-glance know which side is SOURCE and LOAD. Does red for LOAD make sense? LOAD == hot == RED? Black on source? Something else?
[17:24:49] <linux-cnc-bob> hi
[17:26:22] <linux-cnc-bob> im using rhino cam to make gcode and the post generator gives a bit incompatible code, the error is "R clearance plane unspecified in cycle" this is for a G81 canned drilling cycle
[17:26:43] <linux-cnc-bob> the code is here: G81X2.875Y3.475Z0.4886F12.0
[17:27:04] <linux-cnc-bob> I guess it should look something like this instead: G81 X4 Y5 Z-0.6 R1.8 L3
[17:28:18] <linux-cnc-bob> anyone have a good post generator for rhino cam or know how to fix this error?
[17:31:30] <tjb1> Where did you get X4 and Y5?
[17:31:50] <tjb1> Can you paste your post into pastebin?
[17:31:59] <tjb1> Ive dabbled in mastercam post processors
[17:33:59] <linux-cnc-bob> here it is: http://pastebin.com/NFG9Hckb
[17:35:51] <tjb1> The post not the g-code
[17:37:25] <tjb1> Who ever made that post processor was pretty lazy...
[17:38:23] <linux-cnc-bob> ij 1 sec
[17:38:25] <linux-cnc-bob> ok
[17:40:42] <linux-cnc-bob> heres the post: http://pastebin.com/FPs8b1Er
[17:42:55] <tjb1> Look at line 286
[17:43:30] <linux-cnc-bob> CYCLES_DrillNoDwellCodeStart?
[17:43:52] <tjb1> Thats where the G81 cycle code begins
[17:44:08] <linux-cnc-bob> ok so I have to change line 287 I guess
[17:44:31] <tjb1> or 289...
[17:45:13] <linux-cnc-bob> maybe add the "CYCLES_ClearRegister" from line 277?
[17:45:29] <tjb1> There is a R in line 309
[17:45:37] <tjb1> CYCL_Z+CLEAR
[17:46:02] <tjb1> Do you enter an R value in the toolpath?
[17:46:41] <linux-cnc-bob> you mean in the gcode?
[17:46:45] <linux-cnc-bob> or in rhino
[17:46:52] <tjb1> rhino
[17:47:15] <linux-cnc-bob> not sure, I'm in linux right now but I will fire up windows on my laptop
[17:49:36] <tjb1> replace line 289 with this
[17:49:43] <tjb1> and regenerate the gcode
[17:52:45] <linux-cnc-bob> ok I'll try it
[17:53:22] <tjb1> What kind of machine is this
[17:58:24] <linux-cnc-bob> its a cnc3040 from ebay
[17:58:46] <linux-cnc-bob> 300mmx400mm (XY) and about 70mm on Z
[17:59:38] <tjb1> Did you look through the processors on their website?
[18:02:26] <linux-cnc-bob> they are in china I think and didnt see any stuff even for setting up linuxcnc
[18:02:50] <Anon3776> Hello, I'm trying to set up a CNC lathe using a stepper motor to power the spindle. I have edited the .hal file to control the stepper motor (which is connected via step/dir signals) using the normal M3/4 S etc commands. I can't work out how to use it for threading - i.e. G33 and or G73.
[18:03:09] <tjb1> I meant on rhinocam
[18:03:45] <linux-cnc-bob> I did a search once for a rhinocam to linux cnc post processor but didnt see one
[18:03:58] <linux-cnc-bob> I just modified the existing bridgeport one that is in rhinocam
[18:04:55] <linux-cnc-bob> ok I get this line when I run the post you gave
[18:05:23] <linux-cnc-bob> G81X2.875Y3.475Z-0.3886R0.1F12.0
[18:05:36] <tjb1> isnt that what you wanted?
[18:05:54] <linux-cnc-bob> before it was this: G81X2.875Y3.475Z0.4886F12.0
[18:06:03] <linux-cnc-bob> I think so :)
[18:06:06] <linux-cnc-bob> thanks
[18:06:12] <linux-cnc-bob> I just have to put it in linux cnc still
[18:06:16] <tjb1> try that one ^ and see if it adds spaces
[18:06:36] <linux-cnc-bob> I dont mind about the spaces really
[18:06:37] <tjb1> Your current one is stupidly hard to read :)
[18:06:41] <linux-cnc-bob> k
[18:07:00] <tjb1> Youll thank yourself if you ever have to search through it
[18:07:28] <linux-cnc-bob> so where does the 0.1 come from? I gues that is set in linux cnc
[18:07:31] <linux-cnc-bob> for R
[18:07:34] <tjb1> No
[18:07:41] <linux-cnc-bob> sorry meant rhino
[18:07:42] <tjb1> That should of been set when you made the toolpath
[18:07:50] <linux-cnc-bob> ya i think I remember seeing that
[18:08:02] <tjb1> Do you know what R is?
[18:08:45] <tjb1> I dont know how linuxcnc is going to read that
[18:08:55] <tjb1> I think it also requires a G98 or G99 in that line
[18:09:05] <tjb1> atleast Haas does
[18:09:23] <tjb1> Anon3776: Sorry I dont know how to answer your question, someone else here might
[18:11:05] <linux-cnc-bob> it seems to work in linux cnc now
[18:13:05] <Anon3776> It's the first time I've used this, sorry if I put my question in the wrong place - how do I find who to ask?
[18:14:24] <tjb1> Its the right place
[18:14:34] <tjb1> Just you need someone better with linuxcnc to answer your question
[18:16:43] <tjb1> linux-cnc-bob: You may want to research if linuxcnc defaults to G99 or G98
[18:17:53] <linux-cnc-bob> should I hardcode one of them into that line you sent?
[18:20:01] <tjb1> No
[18:20:06] <tjb1> Not unless you need it
[18:20:44] <linux-cnc-bob> ok thx for the help!!!! :D
[18:20:54] <linux-cnc-bob> gotta go back to rhino for a bit
[18:20:56] <linux-cnc-bob> cya
[18:20:59] <tjb1> G98 will make it return to the Z before the G81 starts
[18:21:06] <tjb1> G99 returns it to the R value in the G81 line
[18:21:20] <linux-cnc-bob> ok thanks
[18:21:25] <tjb1> Yep.
[18:29:23] <r00t4rd3d> yawns
[18:29:46] <tjb1> Hey there.
[18:29:55] <tjb1> Started painting :)
[18:50:08] <Nick001-Shop> Will upgrading Axis 2.5.0 Pre 2-626 to current 2.5.1 do anything to a comp that runs good now? And how do I go backwards if it screws up?
[19:00:55] <linux-cnc-bob> hi
[19:02:03] <linux-cnc-bob> I think for the R it is incorrect, if I put 0.1 for R then it will drop down 0.1 after drilling a hole and then Z will go back up 0.1 as it traverses to the next hole to drill
[19:03:39] <tjb1> Put G99 at the beginning of the line after G81
[19:08:37] <linux-cnc-bob> so change this: [SEQ_PRECHAR][SEQNUM][G_CODE] X[NEXT_NONMDL_X] Y[NEXT_NONMDL_Y] Z[CYCL_Z-DEPTH] R[CYCL_Z+CLEAR] F[CYCL_IPM]
[19:09:37] <linux-cnc-bob> ?
[19:24:26] <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.
[19:26:26] <tjb1> No, just input it into your gcode to test
[19:26:33] <tjb1> You need to change that depending on what you do
[19:26:42] <tjb1> linux-cnc-bob: ^^^
[19:43:06] <tjb1> linux-cnc-bob: Did that fix it?
[19:43:23] <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?
[20:06:15] <tjb1> To change the loader, do I just changed it from axis to touchy or is there more?
[20:33:25] <Connor> jdh: Belt Drive conversion done. (Except bearing upgrade, which I'll do this weekend hopefully.
[20:34:14] <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.
[20:39:51] <jdh> did you rebore them or they came that way?
[21:04:38] <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!
[21:04:53] <FinboySlick> Now I'm really bummed out.
[21:05:01] <FinboySlick> There are no visible adjustments for this.
[21:05:26] <jdh> what is it?
[21:05:51] <FinboySlick> jdh: What do you mean? The mill?
[21:05:57] <jdh> right
[21:06:07] <jdh> you have a mill that is un-tram-able?
[21:06:49] <FinboySlick> I'm hoping not but I'm not seeing anything obvious...
[21:07:06] <jdh> what mill?
[21:07:15] <FinboySlick> Syil X5 Speedmaster.
[21:07:23] <jdh> wow
[21:07:50] <FinboySlick> I guess I could kind of shim the spindle motor.
[21:08:05] <jdh> it should be adjustable
[21:08:27] <FinboySlick> I guess so. I'm pealing through the manual now to at least see what part goes where.
[21:08:53] <jdh> for that much $$ it should come with detailed tram instructions
[21:11:24] <Connor> jdh Rebore them. Had too..
[21:11:36] <jdh> with a boring bar?
[21:11:41] <Connor> yes.
[21:11:47] <Connor> video coming in just a second.
[21:12:18] <jdh> guess if you just chuck them, you make the bore concentric to the outside?
[21:16:03] <Connor> correct. Video's up on my thread.
[21:16:07] <Connor> http://www.cnczone.com/forums/showthread.php?p=1171261#post1171261
[21:16:40] <jdh> I was just reading the grease saga
[21:17:12] <ReadError> is cutting cf pretty similar to g10 ?
[21:17:14] <ReadError> speed wise
[21:17:20] <ReadError> ive never cut it before
[21:17:23] <ReadError> but got a sheet
[21:17:30] <jdh> me either
[21:17:59] <FinboySlick> jdh: It has an assembly diagram... And short of shimming, no visible adjustments.
[21:18:23] <jdh> Fin: is the head moveable at all?
[21:18:29] <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.
[21:18:42] <jdh> google for mill tramming
[21:18:53] <FinboySlick> jdh: It's on four linear bearing rails.
[21:19:01] <FinboySlick> I mean two rails, four bearings.
[21:19:21] <jdh> don't screw with teh rails :)
[21:19:43] <FinboySlick> No, obviously. There are four bolts to hold the column to the base.
[21:19:52] <FinboySlick> So I can shim that.
[21:20:06] <FinboySlick> But that's a real bitch to adjust.
[21:21:46] <FinboySlick> The spindle looks like it's held by magic.
[21:22:03] <FinboySlick> No screws, no bolts, for all I know they press-fitted it in.
[21:22:10] <jdh> Connor: looks fine to me?
[21:22:30] <jdh> set screws?
[21:23:12] <FinboySlick> jdh: Doesn't look like it.
[21:23:29] <FinboySlick> jdh: I still have to figure out if it's the column or the spindle that isn't straight.
[21:23:55] <jdh> there is a way to find out, but I don't recall how.
[21:27:22] <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
[21:27:37] <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
[21:27:41] <Tom_itx> try that again...
[21:27:43] <FinboySlick> Tom_itx: With a square on the table?
[21:28:04] <Tom_itx> you don't need a square, use the dial indicator against the table
[21:28:15] <Tom_itx> more accurate
[21:28:22] <Tom_itx> provided the table is level
[21:29:17] <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.
[21:29:54] <jdh> there are detailed instuctions for that somewhere.
[21:29:55] <Tom_itx> then put a straight, long dowel in the spindle and see if it's square with the table
[21:30:01] <jdh> but, dunno how you move yours.
[21:30:15] <FinboySlick> That second to last 'perpendicular' was supposed to be 'parallel'
[21:30:21] <jdh> square the column to the bed, then the spindle to the column
[21:30:37] <Tom_itx> yeah
[21:30:47] <jdh> or the other way aroudn.
[21:30:48] <Tom_itx> the more accurate the measuring tool the more accurate it will be
[21:31:20] <FinboySlick> That's fine and dandy with adjustments. I have to shim that bastard.
[21:31:30] <jdh> http://www.cnczone.com/forums/benchtop_machines/121011-rollies_dads_method_rdm_mill.html
[21:31:43] <jdh> I'd contact the mfg and see if they have tramming docs
[21:32:04] <FinboySlick> That'll be fun...
[21:32:10] <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
[21:32:11] <jdh> en englese por favor
[21:32:22] <FinboySlick> I'll take french too.
[21:32:39] <ReadError> mmmm i love the smell of 3-in-1 oil
[21:33:24] <FinboySlick> ReadError: You can be beaten to death for using that ;)
[21:33:24] <FinboySlick> (Boardwalk Empire)
[21:33:24] <ReadError> oh BWE is good stuff
[21:33:31] <ReadError> im using it for cutting
[21:33:41] <ReadError> it actually works very well on this aluminum tube
[21:33:47] <ReadError> i was melting it before
[21:33:54] <ReadError> now i rub a little on, like butta
[21:34:30] <r00t4rd3d> wtf
[21:35:58] <Tom_itx> FinboySlick, if you run the table back and forth with the dial in the spindle, you can verify the table is flat
[21:36:03] <Tom_itx> in X and Y
[21:36:25] <ReadError> ScribbleJ, you around?
[21:36:33] <Tom_itx> then once it is flat, check the column
[21:40:33] <FinboySlick> Tom_itx: Yes, did that first.
[21:41:45] <FinboySlick> The column would be with a straight pin, no?
[21:42:34] <Tom_itx> ?
[21:43:52] <ReadError> ok nsfw joke kinda
[21:43:53] <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."
[21:44:27] <Tom_itx> lookin for a new gf now?
[21:44:34] <ReadError> lol
[21:55:20] * FinboySlick looks at the inspection sheet from the factory: Chen is a liar.
[21:57:37] <Tom_itx> but you found out after you paid him
[21:57:40] <Tom_itx> all is good
[21:58:38] <FinboySlick> I don't think Chen got to see much of that money.
[21:58:49] <ReadError> whats a good decent sized mill for 3-4k ?
[21:58:57] <ReadError> i want to step up in awesome
[21:59:05] <jdh> BP
[21:59:10] <ReadError> something new
[21:59:12] <ReadError> not all old and rusty
[21:59:20] <ReadError> that will require a bunch of work
[21:59:26] <jdh> you would get a lot more for used than for new.
[21:59:27] <ReadError> i want to fit the electronics and have at it
[21:59:31] <Connor> jdh: Yea. set screws.. You look at it closely.. You can see the run nout ..
[21:59:42] <ReadError> plus i dont have a forklift to move it
[21:59:43] <jdh> connor: I saw it, but...
[21:59:56] <jdh> is the runout in line with the setscrews?
[22:00:10] <Connor> but, the set screws shouldn't effect the runnout.. it's seated against the top of the spindle in a pocket.
[22:00:36] <jdh> the pulley is?
[22:00:41] <Connor> yea.
[22:00:50] <jdh> didn't know they did that.
[22:00:58] <Connor> They don't.
[22:01:25] <jdh> heh. errr... ok.
[22:01:36] <Connor> It has a slighty large bore to set onto of the spindle.. kinda like the RPM disk does..
[22:02:02] <jdh> if the bore is larger, then the setscrew would push it off to one side?
[22:02:11] <Connor> Press fit.
[22:02:41] <Connor> I guess I could open it up a little and adjust it.
[22:03:06] <jdh> did you indicate the ID of the pulley when you chucked it to bore it?
[22:03:35] <Connor> No. :)
[22:03:40] <jdh> I don't know what you would reference with it already bored
[22:03:41] <Connor> Only have a 3 jaw..
[22:04:11] <jdh> it didn't look that bad in the video
[22:04:22] <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.
[22:04:43] <Connor> let me go out and messure it.. brb
[22:04:55] <jdh> is that the new motor or one of the stock ones?
[22:05:20] <jdh> I'm gone... boat leaves at 6am.
[22:05:53] <Connor> Motor is treadmill motor
