Back
[00:13:25] <r00t-Shed> to late/early
[00:14:19] <tjb1> I found it
[00:15:38] <tjb1> Looking at about $25 for a 125-150mm stroke air cylinder
[00:16:54] <r00t-Shed> starrett auto punch
[00:19:00] <r00t-Shed> http://www.drillspot.com/products/509394/starrett_819_automatic_center_punch
[00:19:20] <tjb1> $8 for a solenoid
[00:19:27] <r00t-Shed> thats what someone had and was talking about the other day
[00:19:43] <tjb1> Yeah im not paying $40 because it says starret
[00:19:51] <tjb1> starrett...
[00:20:01] <r00t-Shed> they have them on ebay cheaper
[00:20:33] <tjb1> http://www.youtube.com/watch?v=Y99Uxgg3v3s&feature=player_embedded
[00:21:32] <tjb1> They are about $30 on ebay for used
[00:21:51] <tjb1> Well those still have 3-5 days left
[00:22:32] <r00t-Shed> what do you want one of them for?
[00:22:41] <tjb1> did you watch video?
[00:22:46] <r00t-Shed> no
[00:22:54] <r00t-Shed> i will have to later
[00:22:55] <tjb1> It explains it all in 20 seconds
[00:23:15] <tjb1> center punch on linear rail beside plasma torch connected to air cylinder
[00:23:21] <tjb1> fire to mark holes, etc...
[00:23:37] <r00t-Shed> oh
[00:24:16] <tjb1> Ill go ahead and buy the cylinder if I win the auction on this 7" rail
[00:24:30] <tjb1> I bought a 4" iko rail for the plasma torch for the initial height sensing
[00:24:43] <tjb1> Going to use a microswitch instead of the ohmic sensing
[00:24:55] <tjb1> http://www.ebay.com/itm/200747300054?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649#ht_1772wt_1472
[00:25:26] <tjb1> Put 2 springs to hold the torch down, drive it down until it trips switch and then back up pierce height
[00:25:51] <tjb1> I read about the ohmic hitting areas that might not be conductive and it got me worried so im going with the soft touch and switch
[00:29:55] <tjb1> I guess for that to work it would have to know how far travel is until switch without stock in it
[00:30:31] <r00t-Shed> good thing i have no clue what your talking about.
[00:30:37] <r00t-Shed> :)
[00:31:08] <tjb1> not many plasma people in here is there
[00:31:17] <r00t-Shed> not atm
[00:31:22] <r00t-Shed> well not awake
[00:32:05] <tjb1> ill draw this part on when i have it in my hand
[00:33:08] <tjb1> Ah wish I didnt have to waste time on native american history...
[00:34:27] <r00t-Shed> tell your teacher your racist and dont like red people
[00:38:44] <r00t-Shed> ahh i want to goto bed but this is almost done
[00:46:55] <tjb1> i have to take it

[01:13:23] <r00t4rd3d> :D
[01:14:48] <Jymmm> Hint: Paint/stain BEFORE carving for higher contrast
[01:22:47] <r00t4rd3d> but it would eat out all the stain/paint
[01:23:49] <r00t4rd3d> less depth i guess i could try
[01:24:45] <Jymmm> Try V-Carving yet?
[01:24:55] <r00t4rd3d> some
[01:26:06] <r00t4rd3d> just test though

[02:08:49] <DJ9DJ> moin
[02:42:59] <uw> loin
[02:43:17] <archivist> chops

[06:48:35] <anonimas1> uw: the uvc driver works good, but only if you have the proper camera, I tried it way back.. it was buggy like hell
[06:50:15] <anonimas1> and yay.. my spindle bearings are still alive.
[06:50:30] <anonimas1> tho replacements are on the way anyway so i can swap them and the seals.
[08:50:46] <r00t4rd3d> http://imgur.com/a/572DG
[08:55:42] <r00t4rd3d> anyone use sketchup and phlatscript?
[08:55:58] <jdh> not me
[08:56:29] <jdh> I tried using sketchup for a while, but it seemed to artlike and less precise than I wanted.
[09:03:46] <Jymmm> jdh: It can do some great things, you just really have to get used to it.
[09:04:40] <Jymmm> It had been used to visually inventory every rack in the datacenter
[09:05:00] <Jymmm> ... in 3D (echo goes here)
[09:06:30] <jdh> what is the purpose of a 3d computer inventory?
[09:06:57] <Jymmm> 120 racks
[09:07:18] <joe9> http://codepad.org/AGkDr5nW any thoughts on this error? http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Following_Error says that it is a .ini file error. but, even after changing the ini file, I am not able to figure it out.
[09:07:37] <joe9> error message: "joint 0 following error"
[09:07:39] <jdh> the local community college has a sketchup class. It was very informative and I became proficient, but stopped using it.
[09:08:29] <skunkworks> joe9, can you post your ini?
[09:08:42] <joe9> skunkworks: sure.
[09:09:02] <skunkworks> usually it is that you do not have enough headroom between the stepgen accelleratoin and the joint accelleration
[09:09:13] <joe9> http://codepad.org/ORru0HPx skunkworks.
[09:09:39] <skunkworks> hal?
[09:10:01] <jdh> joe9:did you recently change any config options?
[09:10:07] <joe9> http://codepad.org/LT7yaOSV .hal file
[09:10:36] <joe9> http://codepad.org/KK6AqtLs custom.hal file
[09:10:41] <joe9> skunkworks, ^^
[09:10:56] <joe9> jdh: yes, I was trying to increase the base period setting
[09:11:02] <joe9> from 25000 to 28000
[09:11:04] <jdh> increase or decrease?
[09:11:19] <joe9> as at 25000, I was getting the RTAPI error.
[09:11:35] <joe9> jdh: increased it from 25000 -> 28000
[09:11:56] <joe9> first tried 50000, same joint error, then tried 28000
[09:12:01] <jdh> sounds like your step rate is too high for that base period
[09:12:09] <skunkworks> when do you get the folloing error? moving at high speed?
[09:12:21] <skunkworks> (agreeing with jdh )
[09:12:23] <joe9> skunkworks: while "Home all"
[09:12:35] <joe9> skunkworks: it homes z-axis and y-axis fine
[09:12:52] <joe9> when it is homing the x-axis, it finishes the homing and just before stopping, it gives that error.
[09:13:51] <skunkworks> because it rapids to the actual home position I would guess...
[09:14:19] <skunkworks> HOME_OFFSET = 12.000
[09:14:32] <skunkworks> lower your max velocity
[09:14:44] <jdh> drop vel/accel a bit and see if it goes away
[09:15:43] <skunkworks> 40000 scale is quite high - that is going to limit your max velocity with software step generation
[09:15:44] <joe9> on just the x-axis or both the x and y axes?
[09:15:52] <jdh> X first
[09:15:59] <jdh> then see if the error moves to joint 2
[09:16:02] <joe9> skunkworks: how do I find the "correct" scale?
[09:16:11] <skunkworks> I am going to guess on all - as your scale is the same for all axis.
[09:16:14] <jdh> same velocity though so i tshoudl show up there
[09:16:15] <r00t4rd3d> is an "over head gantry" one that moves
[09:16:49] <joe9> I use the gecko g540 and KL23H276-30-8B.pdf
[09:16:51] <r00t4rd3d> i hate when i have to ask dumb questions
[09:16:54] <joe9> with a taig machine.
[09:17:05] <jdh> you slowed your base period 11%, I'd try kocking that much off max vel
[09:17:13] <joe9> ok, thanks.
[09:17:33] <jdh> joe9: or get a mesa 5i25
[09:17:47] <joe9> jdh: my max velocity is 0.95. do you still think it is a bit high?
[09:17:54] <skunkworks> I don't think you can change the microstepping on the geckos.. So you are stuck
[09:18:03] <joe9> with the step rate, it is ending up to be high. -- you mean?
[09:18:22] <jdh> yoru scale is what it is. You have to work within that limit
[09:18:26] <skunkworks> try .8 for all axis
[09:18:44] <jdh> or do the math
[09:18:58] <skunkworks> you could bump that up until you start getting following errors again. If I was more energetic - we could do the math.
[09:19:00] <jdh> but. .8 should work.
[09:19:00] <skunkworks> heh
[09:19:51] <joe9> skunkworks: ok, doing that. Thanks.
[09:19:58] <skunkworks> let us know
[09:20:32] <skunkworks> but yes - investing in a 5i25 would let you go as fast as the mechanics would allow
[09:20:49] <joe9> btw, the comment character for the .ini file. is it # or ;? it seems to be #, according to what is generated?
[09:20:50] <jdh> 5i25 will get rid of the following error and the rtapi
[09:21:17] <joe9> what is 5i25? let me google that? another hardware piece?
[09:21:40] <jdh> mesanet pci card. You can plug your g540 straight in to it
[09:21:52] <jdh> and it has another port for additional IO
[09:22:25] <skunkworks> plus you can get daughter boards that do a ton more
[09:22:33] <joe9> cool, 0.85 -- no error.
[09:22:45] <anonimas1> it's the best thing I ever bought for my setup :)
[09:23:03] <skunkworks> Great and great ;)
[09:23:41] <joe9> how much is it? where did you get it from? that seems to be a cool idea? does that mean I can put the cnc on any machine? or, does it still have to be within the latency principles?
[09:23:57] <anonimas1> mesanet.com
[09:24:13] <jdh> $90ish
[09:24:15] <anonimas1> it means you can push your hardware to as fast as your motors will allow
[09:24:20] <joe9> anonimas1: thanks, will check up on it.
[09:24:33] <anonimas1> i think most people here went with that kind of setup
[09:24:38] <skunkworks> joe9, your max_linear_veilocity in the traj section should be 1.5
[09:24:58] <jdh> I got a 7i43, before 5i25 came out :(
[09:25:05] <anonimas1> it pretty much means unlimited step rates(also you can stick your microstepping on max and still reach max speed)
[09:25:09] <skunkworks> sqr(.85^2+.85^2+.85^2)
[09:25:30] <Jymmm> 50,000 microstep
[09:25:40] <jdh> zero torque
[09:25:42] <joe9> anonimas1: does the pc need to have decent latency figures?
[09:25:49] <joe9> skunkworks: ok, thanks.
[09:25:57] <Jymmm> jdh: moving silicon wafers
[09:26:05] <anonimas1> yes, but it is not as critical as with software step generation.
[09:26:06] <jdh> joe9: no base period with the mesa
[09:26:32] <skunkworks> It still shoudl be 'good' - I would say less than 50us
[09:27:11] <Jymmm> skunkworks: isn't that high? I thought it was 20uS for paraport?
[09:27:25] <anonimas1> also, with mesa hardware you can always upgrade with encoders and servos later..
[09:27:36] <skunkworks> Jymmm, for mesa hardware
[09:27:58] <anonimas1> same basic cards for input. possibly another for the output to the drives.
[09:29:15] <Jymmm> WOW! I didn't know USR was even still in business... http://www.frys.com/product/5640591?site=sa:adpages%20page:Fri_p15%20date:072012
[09:33:28] <TekniQue> lol usb modem
[09:34:34] <anonimas1> well if my big mill didnt die i'd have a y axis moving today -_-
[09:36:08] <Jymmm> TekniQue: Hey now, I have three modems... USB, USB&Serial Voice, and a Courier
[09:37:01] <Jymmm> all USR now that I think about it
[09:39:01] <Jymmm> I really need to get rid of this stuff, but it takes no room, and all you have to do is need it once to keep saving it.
[09:39:59] <Jymmm> Heh, andy might benefit from the serial concentrator I have
[09:52:18] <r00t4rd3d> does it work on coco pebbles?
[09:59:12] <r00t4rd3d> i designed my first to scale part in sketchup :)
[09:59:17] <r00t4rd3d> i think
[09:59:35] <r00t4rd3d> only sawdust will tell....
[10:12:31] <FredrikHson> yay just got my 4rth axis to work well mostly still have to mount the electronics and do the cables for it
[10:14:31] <skunkworks> Cool
[10:14:40] <skunkworks> Some day I am going to have a 4th axis
[10:14:50] <skunkworks> (one that isn't just an indexer)
[10:14:55] <FredrikHson> this was actually really simple
[10:15:35] <FredrikHson> got an old kuka robot that we didn't use for anything so stole the harmonic drive from that and just mounted a stepper on the back of it
[10:15:59] <skunkworks> nice!
[10:16:26] <FredrikHson> well and a block of iron since the almuminum casing for the drive wasn't exactly sawed of with great accuracy ;)
[10:21:30] <syyl> from experience i can say, that a harmonic drive makes an excellent rotary axis ;)
[10:22:49] <FredrikHson> http://img521.imageshack.us/img521/1937/4rthaxis.jpg
[10:23:13] <FredrikHson> the 80x gear ratio + zero backlash sure is nice can't wait to try it :D
[10:23:16] <JT-Shop> what's the yellow part?
[10:23:26] <skunkworks> part of the robot :)
[10:23:27] <syyl> uh, seems to be a bit more substancial than mine
[10:23:30] <FredrikHson> the and of a robot arm :P
[10:23:35] <FredrikHson> end*
[10:23:38] <JT-Shop> cool
[10:23:40] <syyl> my harmonic drive is only 1:50
[10:23:47] <syyl> and a bit smaller
[10:24:04] * archivist wants!
[10:24:22] * skunkworks starts looking on ebay for robot arms...
[10:24:35] <syyl> hr
[10:24:38] <FredrikHson> its a bit long tbh especially with the chuck mounted but better than my old hand cranked one ;)
[10:24:40] <skunkworks> my puma doesn't have harmonic drives....
[10:24:45] <syyl> and when you are there to pick up the robot arm
[10:25:01] <syyl> you just pull out a sabre saw and cut of the joints
[10:25:09] <syyl> "you can keep the rest"
[10:25:31] <FredrikHson> still got a bunch of those drives leftover but most are not as neat since they are encased in a huge cylinder of iron
[10:25:33] * JT-Shop tries to stay off of flea bay... I just get in trouble
[10:25:52] <syyl> iron is good :D
[10:25:53] <archivist> I wish I knew someone in maintenance at the local car factory
[10:26:05] <FredrikHson> iron is good the huge part isn't
[10:26:23] <syyl> you just need to know where their scrap goes, archivist ;)
[10:26:28] <r00t4rd3d> who is familiar with Sketchup and how to manually enter the part dimensions ?
[10:26:36] <syyl> replaced parts etc...
[10:26:41] <Jymmm> JT-Shop: close your account, that should keep you out of troouble
[10:26:56] <archivist> syyl, dont want it damaged, want it before it gets in the scrap bin
[10:27:07] <FredrikHson> got a maximum of 38deg/s when i tested it 34ish if i put some load on it
[10:27:15] <jdh> r00t: that's where I ran in to the "more art than precision"
[10:27:35] <syyl> hmmm :D
[10:27:47] <r00t4rd3d> well you can manually enter the dimensions
[10:27:51] <jdh> once
[10:28:00] <Jymmm> http://support.google.com/sketchup/bin/answer.py?hl=en&answer=94981
[10:28:11] <FredrikHson> ran it of some 24v powersupply but the xyz runs of another @35 i think so i should get a little more speed not that i need it
[10:28:32] <r00t4rd3d> Jymmm, the proper format is what i am looking for
[10:28:44] <r00t4rd3d> like how to seperate the 2 numbers
[10:28:50] <r00t4rd3d> comma i believe
[10:29:02] <IchGuckLive> hi all B)
[10:29:38] <r00t4rd3d> oh shit hold on
[10:29:47] <r00t4rd3d> i didnt know there was a tool
[10:29:54] <r00t4rd3d> i was just using the box in the lower right
[10:31:07] <IchGuckLive> you need to relod the G-code after changing tooldata
[10:42:00] <IchGuckLive> r00t4rd3d: can i help you in any way
[10:57:26] <r00t-Shed> im trying a litho of willie nelson
[10:57:32] <r00t-Shed> http://i.imgur.com/D24qu.png
[10:57:42] <jdh> I saw a great tatoo of willie once.
[10:58:14] <IchGuckLive> as g-code
[10:59:08] <IchGuckLive> nice did you check it in a visualiser
[10:59:17] <r00t-Shed> i didnt
[10:59:25] <IchGuckLive> hoe it will look after toolpath
[10:59:36] <r00t-Shed> nope, dont know how
[11:00:20] <r00t-Shed> is that a program?
[11:01:16] <IchGuckLive> freemill etc
[11:01:24] <r00t-Shed> oh
[11:01:40] <r00t-Shed> i just cut stuff and see how it looks when its done
[11:01:40] <IchGuckLive> some kind of this
[11:01:49] <IchGuckLive> O.O B)
[11:02:37] <r00t-Shed> how come people with nema 17 motors can set their velocity to 2.5 but i can only set my 23's to 0.2?
[11:03:26] <cpresser> inch vs mm, r00t-Shed?
[11:03:37] <r00t-Shed> no
[11:03:57] <jdh> they have different machines?
[11:04:04] <IchGuckLive> r00t-Shed: they got better parport
[11:04:32] <jdh> are you limited due to step speed, stalling, or what?
[11:04:36] <r00t-Shed> the d525 parport isnt good?
[11:04:40] <IchGuckLive> r00t-Shed: what controller do you got
[11:04:48] <r00t-Shed> if i set to like 2 they just buzz
[11:04:52] <jdh> cheap chinese 6560
[11:04:57] <r00t-Shed> yeah
[11:05:11] <IchGuckLive> ah dies does faol ZEN is not working that fast
[11:05:35] <IchGuckLive> with the gecko or leadshine on the D525 you will go 10times that fast
[11:06:18] <r00t-Shed> can you buy me a gecko?
[11:06:18] <IchGuckLive> r00t-Shed: did you modify the Zen TB6560
[11:06:31] <r00t-Shed> i didnt, its not from zen though either
[11:06:38] <r00t-Shed> ebay chinaman special
[11:07:01] <IchGuckLive> they are al made by zen factury the red and the blueone
[11:07:14] <r00t-Shed> i got the blue one
[11:07:28] <IchGuckLive> you need to get the 100pF of replace it with 150pF
[11:07:38] <IchGuckLive> 1000pf
[11:07:48] <IchGuckLive> -> 150pf
[11:08:05] <IchGuckLive> then you got clock 400kHz
[11:08:14] <IchGuckLive> now you got 20kHz
[11:08:31] <r00t-Shed> is there a guide for that someplace?
[11:08:32] <IchGuckLive> then you will hear no noice from the motors
[11:08:41] <IchGuckLive> you wiull think the mashine is not running
[11:08:59] <jdh> in his case, it isn't running.
[11:09:09] <r00t-Shed> its walking
[11:09:15] <jdh> not at 2.0
[11:09:23] <r00t-Shed> 0.2
[11:10:01] <jdh> do you have the timings set correctly?
[11:10:01] <r00t-Shed> what is a pF? Cap , fuse , chip? is it smd?
[11:10:08] <IchGuckLive> did you go base100000 servo 1Milion 20000 20000 5000 5000
[11:10:10] <jdh> through hole caps
[11:10:17] <r00t-Shed> nice
[11:10:20] <IchGuckLive> its smd
[11:10:32] <r00t-Shed> through hole or smd?
[11:10:35] <IchGuckLive> one per stage at the bottom print
[11:10:57] <jdh> mine has through-hole caps
[11:11:08] <Connor> I had a 4th Axis version.. I replaced the cap to eliminate the high pitched squeal my wife could hear but I couldn't.
[11:11:13] <Connor> it's fixed now. :)
[11:11:29] <jdh> connor: how's the mill? anything happening?
[11:11:33] <Connor> this was a surface mount on the back of board.
[11:11:40] <Jymmm> Connor: your wife is a bitch?
[11:12:16] <Connor> jdh: Nothing ATM.. I got the air cylindar, but, not $$$ to order any stock to finish up the build..
[11:12:42] <Connor> Jymmm: Um.. No. Just has better ears. Mine are damaged from fan noise from working in a datacetner.
[11:12:55] <r00t-Shed> http://i.imgur.com/vrNIS.jpg
[11:13:02] <Jymmm> Connor: LOL, you didn't get the joke =)
[11:13:09] <Connor> r00tSame one as I have.
[11:13:10] <r00t-Shed> someone circle what needs changing?
[11:13:12] <jdh> it wasn't funny.
[11:13:15] <Connor> Jymmm: and not a dog either.
[11:13:40] <Jymmm> Connor: Hey, if she is the only one that can hear HF...
[11:13:41] <jdh> that pic looks much better than mine.
[11:13:57] <Connor> r00t-Shed: Need the backside.. the surface mount cap is on the bottom
[11:14:26] <r00t-Shed> i will have to get one later
[11:14:48] <Connor> Thread on CNCzone all about this... but I ONLY did the modification for the cap.
[11:14:55] <Connor> nothing else.
[11:15:05] <jdh> other is opto-removal?
[11:15:08] <Jymmm> Connor: And really? You worked in a DC and didn't bother to get/use earplugs after two weeks?
[11:15:13] <Connor> jdh: Yea, I didn't bother.
[11:15:25] <r00t-Shed> http://img.sunsky-online.com/upload/store/detail_raw/S-EMC-0105_3.jpg
[11:15:28] <r00t-Shed> that is the back
[11:15:33] <Connor> jdh: I may have done the mod to turn of the lame idle dedication..
[11:15:40] <IchGuckLive> http://forum.zerspanungsbude.net/download/file.php?id=7979&t=1 r00t-Shed the tyni smd thats on the tb6560
[11:15:41] <r00t-Shed> oh wait thats not the same
[11:16:22] <Jymmm> Connor: Even earbuds make a huge difference
[11:16:25] <Connor> Jymmm: My office was attached to the datacenter..
[11:16:29] <jdh> anyone have 3 or 4 dirt cheap 17's they want to get rid of?
[11:16:52] <Jymmm> Connor: was your office *IN* the DC?
[11:17:17] <Connor> No. Attached. I.E. I walk out the door and I'm in the Datacenter.
[11:17:56] <Jymmm> Connor: so someone couldn't get to your office w/o going into the DC?
[11:18:06] <Connor> Exactly
[11:18:27] <Jymmm> whos fucked up idea was that?
[11:18:36] <Jymmm> clearly not a DC designer
[11:18:51] <Connor> It was a small ISP that started out as a Computer Repair place..
[11:18:57] <Jymmm> he
[11:18:59] <Jymmm> h
[11:19:12] <Connor> Not a huge datacenter... we're talking 7 or so racks..
[11:19:15] <Jymmm> still, if they had ever been in a DC they should have known better
[11:19:58] <Connor> I had plans to put a wall up so that would be better..but, never got the chance to do it.
[11:20:24] <Jymmm> 7 racks? That's not a DC imnso
[11:20:30] <Connor> and.. it happened over time.. Originally only had 1 rack.
[11:20:39] <Jymmm> that's a closet with a AC
[11:21:20] <Jymmm> you had UPS too?
[11:21:23] <Jymmm> generator?
[11:21:37] <Connor> Jymmm: Yea, with T3, ATM, 20 or so T1's, huge ass USP
[11:21:50] <Connor> err. UPS
[11:22:07] <Jymmm> generator?
[11:22:12] <Connor> Yes.
[11:23:02] <Jymmm> 20 T1's? that musta been a pita
[11:23:24] <Jymmm> (provisoning)
[11:24:04] <Connor> No. Bellsouth brought in 23" rack.. Broke out the T3, the ATM and used the 3rd T3 for the T1's.
[11:24:42] <Connor> feed them into a rj45-X panel that was installed in my wire rack.. and I could patch into them.
[11:25:11] <Jymmm> not cabling, provisioning.
[11:25:12] <Connor> they were Point-to-point T1's for customers and other points of presences.
[11:25:35] <Jymmm> POP's oh gawd
[11:25:44] <Connor> Dealing with the Teleco's always a PITA.
[11:25:58] <Connor> some of the T1's were for PRI's too
[11:26:17] <Jymmm> you had ISDN too?
[11:26:30] <Connor> I think we had somewhere up to 8 to 12 PRI's at some point.
[11:26:33] <Connor> Yea. and Dialup.
[11:26:41] <Jymmm> lol
[11:26:53] <Connor> and the ATM was for DSL
[11:26:54] <Jymmm> that some scarry shit back then
[11:27:09] <Connor> Was the fastest thing until cable and DSL.
[11:27:24] <Connor> and in TN was VERY affordable.
[11:27:44] <Jymmm> Yeah, uh huh, Courier Total Control can just kiss my ass!
[11:28:16] <Connor> We used a 3Com/USRobotics Total Control..
[11:28:30] <Jymmm> I know =) Everybody did
[11:28:57] <Jymmm> and power cycle the SOB every couple of days =)
[11:29:04] <Connor> No. We were the only ones in Knoxville to use them.. everyone else used Ascend and TNT Max's or portmasters
[11:29:49] <Jymmm> You were uber if you had zylogic (?) modem =)
[11:29:52] <Jymmm> zylog?
[11:29:58] <Jymmm> sumtin like that
[11:30:12] <Connor> We didn't use those..
[11:30:50] <Connor> When we started out.. it was a Windows NT term server using a Rocket Port 16 with a bunch of USRobotics 33.6k modems hanging off of it on analog.
[11:31:20] <Connor> Sportsters I believe even.
[11:31:20] <Jymmm> rocket port. HAHAHAHAHA I remember that thing
[11:31:41] <Jymmm> huge hunka boat anchor these days
[11:32:13] <Connor> In the end, we were doing dialup analog, ISDN. Dedicated ISDN, DSL, T1's Wireless and VoIP.
[11:32:33] <Jymmm> Heh, I have a 24 port serial concentrator sitting on the shelf =)
[11:35:07] <Connor> Most of the fan noise came from the last rack that we added.. it was the one all the 1 and 2U machines went into.. which have those ridiculously loud and high flow muffin fans. It went right next to the office door.
[11:35:39] <Connor> I ended up putting in a office divider next to it to deflect the sound out of the office when the door was open.
[11:36:05] <Jymmm> My box hostname was 'banchee', it had 6x 15K RPM fans in it =)
[11:36:58] <Jymmm> In a row of 60 racks, I could close my eyes, walk down the isle and just HEAR when I got to my rack =)
[11:38:01] <Connor> Those were the days... Worked for them from summer of 95 till November of 08. I saw writing on the wall. Wife did webdesign and we hosted with them.. so.. I went part time for a month or so.. moved all my clients off onto my own server in another local datacenter.. In March of 09 they sold out. :)
[11:38:26] <taiden> so im having the strangest problem
[11:38:40] <taiden> i have z travel of 0 to +4.5
[11:38:45] <taiden> i'm at z2
[11:38:49] <Connor> moved most of it to Nashville...
[11:39:01] <taiden> g0 z4 gives me a "Linear move in MDI would exceed joint 2's positive limit"
[11:39:09] <Connor> I ended up with a few of the Colo's they were hosting because they wanted to stay with someone they knew and someone local in Knoxville.
[11:39:14] <taiden> i have cleared g92 offsets
[11:39:25] <taiden> but the numbers on the DRO dont match up with what i punch into MDI
[11:39:50] <Connor> taiden: Most of my Z is in negative.. 0 at the top -4.5 would be at the bottom.
[11:40:58] <skunkworks> taiden, http://wiki.linuxcnc.org/cgi-bin/wiki.pl?CoordinateSystems
[11:41:16] <skunkworks> taiden, http://wiki.linuxcnc.org/cgi-bin/wiki.pl?CoordinateSystems#So_if_you_re_lost_what_should_you_do
[11:42:03] <Connor> jdh: I think I've come up with a way to have my PDB and still keep the quill without having to remove the PDB..
[11:50:30] <taiden> and it's stopping me from picking up where this toolpath left off when my computer crashed
[11:51:58] <Connor> (12:28:52 PM) Connor: taiden: Most of my Z is in negative.. 0 at the top -4.5 would be at the bottom.

[12:17:10] <IchGuckLive> r00t-Shed: how is the progress
[12:22:24] <r00t-Shed> im not doing anything
[12:22:28] <r00t-Shed> learning sketchup
[12:34:07] <Loetmichel> re @ home
[12:34:39] <IchGuckLive> r00t-Shed: why not blender
[12:35:07] <IchGuckLive> or for milling librecad eqals autocad R12
[12:41:50] <ReadError> sketchup is a waste
[12:43:56] <IchGuckLive> from sketchup via blender and heekscad to cnc
[12:48:10] <IchGuckLive> heekscad
[13:00:53] <JessicaRN> Hola folks! a friend is letting me borrow his fireball. he hasn't used it in a couple of years. I've not used emc yet, but when I start it up it terminates with an error. anyone willing to help me decipher the error msg?
[13:02:17] <Jymmm> JessicaRN: Just post you error msg somewhere, give a link and ask your quesiton. If someone can help, they'll respond.
[13:03:01] <JessicaRN> no net connection on that box, so cutting and pasting isn't an option just now
[13:03:18] <Jymmm> sneakernet
[13:05:13] <JessicaRN> ugh
[13:06:26] <archivist> how do we decipher a message we cannot see/read
[13:06:42] <tjb1> http://www.latimes.com/news/nation/nationnow/la-na-nn-dark-knight-shooting-20120720,0,2147749.story
[13:08:19] <JessicaRN> archivist: I thought you were psychic
[13:08:53] * Jymmm resists the urge and bites tounge!
[13:08:59] <JessicaRN> actually, looking over the error dump, it looks like it is not finding the parport
[13:09:07] <Jymmm> archivist: =)
[13:09:12] <archivist> battery failed in my crystal ball
[13:09:23] <tjb1> SMC has a really poor website :( cant find any info on this actuator
[13:10:08] <Jymmm> archivist: http://www.polyvore.com/battery_powered_crystal_ball_target/thing?id=10273298
[13:10:15] <JessicaRN> I'm looking at the error msg now and holding my fingers to my temples to act as antenna. now I'm thinking about it REAL HARD!!! Is it coming thru yet?
[13:11:14] <JessicaRN> any way to check the parport easily?
[13:11:54] <IchGuckLive> JessicaRN: does it loead a Simulation mashine
[13:12:03] <IchGuckLive> in the sim folder ?
[13:12:34] <IchGuckLive> what version is displayed at the startup
[13:12:50] <JessicaRN> no, doesn't seem to. I click on the EMC2 icon and a get the splash screen. then, a second later, i get the error dump
[13:13:15] <IchGuckLive> please load from menue not the icon
[13:13:29] <IchGuckLive> application cnc
[13:13:33] <JessicaRN> ver 2.2.5 according to the error dump
[13:13:43] <IchGuckLive> oh way back
[13:13:54] <IchGuckLive> we are working on 2.6
[13:14:06] <pcw_home> ancient history
[13:14:13] <IchGuckLive> 2.5 is standard and 2.4 is the recomendet
[13:14:27] <JessicaRN> the box has been in storage for like 3 years, so no surprise there
[13:14:53] <IchGuckLive> we had 2.3.5 3 years ago
[13:15:12] <JessicaRN> i opened up the app from the menu and then selected the config. after, i get the same think as before
[13:15:26] <IchGuckLive> i dont think anyone is able to get beond your error
[13:15:51] <JessicaRN> cool... I'll rig up a net connection and d/l the newer emc
[13:16:18] <IchGuckLive> i think there is simply no RTI kernal running
[13:16:45] <IchGuckLive> JessicaRN: where are you from the USA
[13:16:55] <JessicaRN> Indiana. Why?
[13:17:03] <IchGuckLive> ok im sitting in Germany
[13:17:15] <Loetmichel> ... ahh, 408 of 750GB rescued. i LOVE ddrescue. it seems my fileserver will live again tomorrow... note to self: BACKUP next time... ;-)
[13:17:20] <IchGuckLive> so im off thrue to time
[13:17:59] <JessicaRN> while I have you all here, can anyone offer suggestions for good, free stl->toolpath generators
[13:18:00] <IchGuckLive> JessicaRN: http://buildbot.linuxcnc.org/ is today ofline
[13:18:38] <JessicaRN> shite, so when will it be back up?
[13:19:07] <pcw_home> just download the 2.5 ISO
[13:19:13] <IchGuckLive> just checking that
[13:19:42] <IchGuckLive> JessicaRN: is it a standard 3 axis mashine
[13:20:17] <JessicaRN> yeah
[13:20:20] <IchGuckLive> and what os are you on
[13:20:22] <JessicaRN> it's a fireball v90
[13:20:34] <IchGuckLive> ubuntu hardy
[13:20:43] <JessicaRN> the box is running an old ubuntu right now.
[13:20:57] <andypugh> LiveCD is the easy way
[13:20:58] <JessicaRN> dunno which ver
[13:21:16] <andypugh> Is there anything on that machine that you want to keep?
[13:21:21] <IchGuckLive> so i guess if you like i woudt go with your box to ubuntu 10.04 and linuxcnc 2.5
[13:21:48] <IchGuckLive> ok im off folks thanks for talking BY B) O.O
[13:22:24] <JessicaRN> I'm chatting to you from a different box
[13:23:13] <JessicaRN> andy, yeah, I need to keep the data because it's not my setup. it's a friends. he has had it in storage for like 3 years
[13:23:53] <JessicaRN> I'm debating on dropping a different HD in it and just starting from scratch
[13:24:29] <JessicaRN> So, how does EMC2 compare w/ MACH3?
[13:25:30] <jdh> let's talk about religion instead
[13:25:41] <tjb1> Ones for stupid, ones for smart :)
[13:26:24] <jdh> too late.
[13:27:26] <JessicaRN> lol
[13:29:47] <JessicaRN> but, serious, folks. what are your thoughts
[13:31:15] <tjb1> Im serious
[13:31:26] <jdh> think about where you are, then think about what kind of response you expect to get here.
[13:31:30] <tjb1> One is for people that know all about computers and linux
[13:31:47] <jdh> I disagree with that statement.
[13:32:13] <tjb1> You need a pretty strong grasp of linux to use linuxcnc
[13:32:22] <tjb1> Well not use it…to do more than just use it
[13:32:32] <JessicaRN> actually, from an informed and intelligent audience, I would hope to get and informed and thoughful response. we're not fundimentalists, are we?
[13:32:59] <alex4nder> I am.
[13:33:03] <JessicaRN> lordy
[13:33:43] <JessicaRN> fundies from any group are scary.
[13:33:59] <jdh> yep.
[13:34:10] <pcw_home> sorry you are wrong and will go to hell
[13:34:36] <JessicaRN> i don't like to drink the kool-aid. I like to make an informed decision. So, in that light will someone kindly offer their thoughts?
[13:35:00] <alex4nder> JessicaRN: I'm thinking about buying a burrito
[13:35:06] <alex4nder> that's my current thought.
[13:35:26] <JessicaRN> pcw, I'm a Catholic lesbian. I already know I'm going to hell. I'll have a lot of fun before I get there though.
[13:35:29] <alex4nder> JessicaRN: do you want to know if you should run EMC or not?
[13:35:42] <archivist> you are trying to compare a hammer with an engineers toolkit
[13:36:10] <jdh> good description.
[13:36:24] <jdh> but, you can get a lot done with a hammer.
[13:36:35] <archivist> but it looks bent
[13:36:46] <alex4nder> JessicaRN: EMC works, but don't expect to not have to work to use it.
[13:36:57] <alex4nder> it works great.
[13:37:02] <JessicaRN> see, that is an extremists statement. if you feed g-code to either tool they will run a mill. there is not -that- much difference. and, if there is, please just offer some points to support your statement. that's all i'm asking for.
[13:37:09] <alex4nder> and sometimes drills holes in your mill-table on accident.
[13:37:25] <archivist> emc can do whatever you want, may need to think a bit though
[13:37:27] <alex4nder> JessicaRN: if you don't know, why are you asking people to prove something to you?
[13:38:02] <JessicaRN> serious, folks... do you really have to ask that question?
[13:38:11] <alex4nder> what?
[13:38:19] <JessicaRN> are you a republican just cuz your dad told you to vote that way?
[13:38:28] <JessicaRN> or do you make your own decisions?
[13:38:38] <archivist> JessicaRN, you can extend emc, make your own kins for special machines etc
[13:38:38] <alex4nder> well I'd start by learning about politics.
[13:38:42] <JessicaRN> I'm asking for an informed and intelligent argument
[13:38:56] <alex4nder> JessicaRN: there's no argument.. go use Mach3 if you want
[13:39:14] <jdh> if mach does all you need, then it doesn't really matter.
[13:39:16] <JessicaRN> and, alex, I'm asking you about the pros and cons of emc vs mach3. I'm trying to become informed.
[13:39:23] <archivist> it has realtime feedback so is a better machine control
[13:39:48] <JessicaRN> archivist: thank you. finally, a data point
[13:39:52] <alex4nder> JessicaRN: if this were religious, I think most of LinuxCNC users would be buddhists.
[13:39:56] <jdh> it has closed look control
[13:39:58] <pcw_home> Yeah IMHO LinuxCNC is flexible, open, powerful but not terribly polished Mach is commercial/closed windows only ,fairly polished
[13:40:00] <pcw_home> LinuxCNC make a lot of the real time guts available for extension, Mach has only minimal reall time capabilities (just the software step generation I believe)
[13:40:42] <JessicaRN> thank you again... that is the kind of thing I was asking for.
[13:40:55] <alex4nder> do you even understand what any of that means?
[13:41:01] <JessicaRN> how stable is the current EMC compared to mach?
[13:41:17] <archivist> emc can drive up to 9 axes at the same time
[13:41:19] <JessicaRN> alex, you are a condecending little pud
[13:41:28] <alex4nder> sick response
[13:42:46] <JessicaRN> yes, bonehead, I understand. btw, my first career of 20 some years had me designing some of the largest SANs and WANs in the world.
[13:43:16] <JessicaRN> all while you were still wetting your ditties
[13:43:35] <archivist> oy some of us are older in here :)
[13:43:43] <jdh> if not most
[13:43:45] <alex4nder> yup
[13:43:59] <JessicaRN> jim jones would have loved you, alex. you follow without question.
[13:44:13] <alex4nder> what?
[13:44:16] <jdh> this sounds like most #linux windows conversations of the last 20 years
[13:44:22] <alex4nder> haha
[13:45:13] <JessicaRN> actually, a conversation would be nice. I wasn't asking about linux vs windows. I was asking about two specific apps
[13:45:26] <jdh> it's pretty much the same conversation though
[13:45:36] <jdh> for about the same reasons
[13:45:42] <pcw_home> Because Mach depends on external hardware for real time (beyond simple step generation)
[13:45:44] <pcw_home> advanced function like rigid taping and threading are interface hardware dependent
[13:45:46] <pcw_home> (the hardware must handle the synchronization)
[13:45:47] <pcw_home> LinuxCNC does all these advance functions in real time software so they work with any interface hardware (in the same way)
[13:45:59] <rob_h> backdrops
[13:46:11] <JessicaRN> pcw_home: thank you
[13:46:19] <JessicaRN> great answer
[13:47:43] <JessicaRN> with a simple mill like the fireballl, it has minimal feedback. really all it has is limit switches. so, that is a strength in some environments, but not in this one. correct?
[13:47:49] <jdh> linux and/or linuxcnc is technically superior, windows and/or mach3 is prettier and arguably easier to use
[13:48:41] <JessicaRN> I agree, jdh, but there is a point you forget. linux support tends to suck.
[13:48:44] <jdh> for a router like that, I don't think either of them is inherently better.
[13:49:04] <jdh> I would disagree with that also.
[13:49:31] <jdh> linuxcnc support is exceptional IMO
[13:49:35] <alex4nder> yup
[13:49:39] <pcw_home> Yes on a simple mill and if you dont want to do rigid tapping of other fancy things I think its a tossup But I do think Linux is less likely to break itself than windows
[13:49:42] <JessicaRN> with a commercial product like mach, the publisher has to support it or they get a bad rep. for EMC, I'll need to ask help from the likes of alex... ugh!
[13:50:04] <JessicaRN> pcw_home: without a doubt
[13:50:13] <JessicaRN> linux is MUCH more stable
[13:50:19] <pcw_home> Actually I think LinuxCNCs support is top notch (see the forum)
[13:50:28] <alex4nder> JessicaRN: you've been SANing and WANing for 20 years, you'll have this software on lock-down in no time.
[13:50:36] <alex4nder> I'm surprised you're even asking questions.
[13:50:39] <JessicaRN> how many windows boxes have you seen with multiple year uptime? none.
[13:51:08] <r00t4rd3d> tons
[13:51:20] <JessicaRN> alex, go back to your pocket pool and let the adults talk
[13:51:36] <jdh> ok, she's got you there.
[13:51:43] <alex4nder> haha
[13:51:54] <alex4nder> JessicaRN: I feel like this is elementary school, and you're trying to date me.
[13:51:58] <alex4nder> if I had pigtails, you'd be pulling them.
[13:52:02] <JessicaRN> linux is much more reliable than windows
[13:52:22] <jdh> we all agree on that, so why bother with mahc
[13:52:23] <r00t4rd3d> nonsense
[13:52:26] <r00t4rd3d> i dont
[13:52:32] <JT-Shop> this conversation seems more suitable to the #smack-talk channel
[13:52:37] <jdh> yep
[13:52:49] <alex4nder> JT-Shop: it'd have to be sharper, with more comedic value.
[13:52:58] <JT-Shop> lol
[13:53:15] <tjb1> r00t4rd3d: you make anything new since last night?
[13:53:28] <JessicaRN> so, forget the emc/mach debate
[13:53:39] <jdh> as I said, religino is a better conversation
[13:53:48] <r00t4rd3d> tjb1, nothing worth taking a picture of
[13:53:50] <JessicaRN> any good tools for STL>toolpath?
[13:54:07] <jdh> windows definitely wins for CAM
[13:54:18] <tjb1> The map is pretty cool
[13:54:44] <JT-Shop> OneCNC is getting better
[13:55:11] <andypugh> One advantage of LinuxCNC is that if it doesn't have a feature you want you don't have to persuade the developer to add it for you, you can add it yourself, or get any other programmer to do it for you.
[13:55:12] <JessicaRN> Well, I can create the gcode on anything and just send it over to the machine that runs the mill. so platform is irrelevant
[13:55:44] <JessicaRN> OneCNC?
[13:55:57] <JT-Shop> cam program
[13:56:02] <andypugh> LinuxCNC is also rather more modular, For example you can use only the HAL layer to do simple things like driving steppers.
[13:56:05] <jdh> from the early 80's
[13:56:38] <JessicaRN> any decent freeware?
[13:56:57] <JT-Shop> no
[13:57:23] <JessicaRN> what about the rhino free offering? worth looking at?
[13:58:14] <jdh> depends on what you want to cut. There might be suitable free tools depending on complexity. Or write the code by hand.
[13:58:36] <JessicaRN> it might all be irrelevant. I may be getting bobcam for free. never used it, but it gets decent reviews
[13:59:15] <JT-Shop> all those reviews are from bobcad sales people LOL
[13:59:16] <tjb1> I may sign up for the trial of bobcad-cam just so they call and ill work them down to like $10
[13:59:43] <JT-Shop> you'll get email from them the rest of your life
[13:59:50] <JT-Shop> 3-4 a month
[14:00:01] <JessicaRN> thats what a spam account is for.
[14:00:09] <tjb1> I have a special email for that
[14:00:09] <Loetmichel> JT-Shop: and thats different from other cad companies?
[14:00:16] <JessicaRN> i have an email addr that i only use for that kinda stuff
[14:00:35] <Loetmichel> i get about 5 different "newsletter" from cad sellers...
[14:00:39] <JT-Shop> OneCNC donesn't bother me much with email, I've gotten 1-2 maybe a year from them
[14:00:42] <JessicaRN> so, has anyone used bobcam?
[14:00:42] <tjb1> I dont access this email so much that yahoo deactivates it
[14:00:46] <Loetmichel> tried to shut them off: no avail...
[14:00:46] <JT-Shop> yes
[14:00:47] <jdh> JT: is it expensive?
[14:00:58] <JT-Shop> what is "IT"?
[14:01:02] <jdh> onecnc
[14:01:16] <JT-Shop> middle of the road for price
[14:01:27] <JT-Shop> of course depends on the package level you get
[14:01:35] <tjb1> Oh goody, bidding war on ebay
[14:03:40] <JT-Shop> anyone want to come over and finish the converstion on my BP while I take a nap?
[14:04:34] <JT-Shop> hmmm no one is jumping at that chance...
[14:04:54] <pcw_home> A little off topic but I also think LinuxCNC would be really good in an educational or research
[14:04:56] <pcw_home> environment since its so modular, flexible and open. Not necessarily just for CNC but for robotics
[14:04:58] <pcw_home> and other complicated motion /realtime I/O systems
[14:04:59] <pcw_home> (a HAL centric view where "motion and Gcode parsing" is just a HAL comp like any other)
[14:06:02] <JT-Shop> that seems to be more on topic than the conversation has been :)
[14:06:51] <jdh> I spent half of yesterday with some parker-compumotor 6k8 indexers. A linuxcnc component that replaced that would be nifty
[14:09:27] <skunkworks> aww - I missed out
[14:09:44] <jdh> skunkworks: how about those baptists?
[14:10:22] <anonimas1> I am using bobcad/cam.. it works fairly decent
[14:10:47] <skunkworks> jdh, we have used a lot of parker/compumotor stepping drives - Most you can remove the indexers and do strait step/dir
[14:11:03] <skunkworks> oem650,750 and s iirc
[14:19:45] <jdh> skunkworks: you can on all of them. The indexer is just nice for control
[14:20:59] <jdh> multi axis motion profiling, limits, digital IO, programmable
[14:31:09] <Connor> jdh: You using linuxcnc at work too ?
[14:35:34] <skunkworks> is there a way to check to see if isolcpus took?
[14:37:44] <jdh> Connor: nope, it woudl be nice to not have to buy an indexer though
[14:38:14] <jdh> 6k8 is like $4500 new
[14:39:11] <tjb1> http://www.youtube.com/watch?v=oBMT3OMEPwk
[14:41:14] <Connor> what is a 68k?
[14:41:17] <Connor> err. 6k8
[14:41:21] <jdh> skunkworks: anything in dmesg to indicate they do?
[14:41:31] <cradek> Connor: 6.8 kOhm resistor
[14:41:32] <jdh> an 8 axis motor controller
[14:41:32] <skunkworks> I was looking = seems to be
[14:41:58] <Connor> cradek: not in the context jdh is referring too.
[14:42:04] <skunkworks> this latest amd/asus motherboard we got in sucks. (for latency)
[14:42:12] <skunkworks> 30Kish
[14:42:32] <cradek> oh
[14:43:07] <jdh> does serial, ethernet. steppers & servos, IO for limits, motion profiling, runs 'X' programs
[14:43:39] <skunkworks> amd a6-3500 processor with a f1a55-m lx plus motherboard
[14:43:42] <skunkworks> 3 core
[14:44:03] <skunkworks> (some random motherboard/cpu combo from newegh
[14:44:04] <pcw_home> gimpy 4 core?
[14:44:21] <skunkworks> no clue what they do
[14:44:43] <jdh> why did you get an amd board?
[14:45:00] <skunkworks> I added a pci-e video card and also tried isolcpus=2
[14:45:08] <skunkworks> asus
[14:45:12] <pcw_home> 30K should be fine except for software step gen
[14:45:16] <skunkworks> yes
[14:48:55] <pcw_home> For servo thread only machines where jitter is an issue seems like the servo thread could
[14:48:57] <pcw_home> have code at the beginning of the tread invocation that waits for the HS clock to get to the right tic
[14:48:59] <pcw_home> (that is is you have 30 usec worst case latency you wait for up to 30 usec and remove the jitter)
[14:49:45] <pcw_home> wastes a few % of the CPU
[14:50:29] <pcw_home> s/tread/thread/
[14:51:26] <pcw_home> that should get the jitter down to < a usec or so
[14:52:09] <skunkworks> now - (granted I don't know much about it) I thought jitter was + and _
[14:52:10] <skunkworks> -
[14:52:45] <skunkworks> +/-
[14:52:52] <pcw_home> there may be a factor of 2 forgotten there somewhere
[15:07:50] <tjb1> 13 minutes left to snipe
[15:08:10] <jdh> you too?
[15:08:23] <tjb1> ebay?
[15:08:35] <jdh> that's mine, bitch.
[15:08:41] <tjb1> nooonoo
[15:09:03] <tjb1> im winning
[15:09:48] <jdh> for now.
[15:10:04] <taiden> hello gents
[15:10:53] <tjb1> You cant beat me
[15:10:56] <tjb1> My wallet is huge.
[15:11:20] <tjb1> Heh I like how standard shipping cost $8 more then expedited shipping
[15:13:15] <andypugh> pcw_home: There is an RTAI config option to busy-wait. I wonder if it does that?
[15:13:53] <tjb1> Hey jdh you just got outbid.
[15:14:42] <Tom_itx> link?
[15:14:46] <Tom_itx> i wanna watch
[15:15:06] <tjb1> Im not really bidding him :)
[15:15:08] <tjb1> But I am gonna snipe someone
[15:18:26] <tjb1> 2 min 30 secs
[15:20:14] <andypugh> I wonder how big this is? It looks unusually sturdy for they type. http://www.ebay.co.uk/itm/330765603181
[15:20:36] <tjb1> http://www.ebay.com/itm/300741719136?ssPageName=STRK:MEBIDX:IT&_trksid=p3984.m1431.l2649&autorefresh=true#ht_3901wt_1165
[15:20:59] <Tom_itx> andypugh i'd venture a guess of 8 or 10"
[15:21:13] <tjb1> oooh i got sniped lol
[15:21:27] <Tom_itx> based on the fact the square hole is probably 1/2 or 5/8"
[15:21:43] <JT-Shop> andypugh: can you scale it by the leaf?
[15:21:44] <andypugh> I can't afford too much centre height.
[15:21:49] <Tom_itx> i know
[15:21:51] <Tom_itx> me either
[15:22:00] <Tom_itx> you got more room than i do
[15:22:28] <JT-Shop> 100lbs must be a 6" chuck or there abouts
[15:22:38] <andypugh> Normally dividing heads have the chuck on a spindle, and are a little flexible.
[15:22:53] <andypugh> I figure I could use the jaw-slots as T-slots for general workholding
[15:23:30] <andypugh> It's badly advertised. I like badly-advertised
[15:23:59] <Tom_itx> heh
[15:24:57] <andypugh> I especially like browsing business, office and industrial / metalworking/milling/welding with the "for parts or not working" filter on :-)
[15:25:00] <Tom_itx> andypugh if it's too big you can always sell it to JT-Shop
[15:25:13] <andypugh> If he pays postage
[15:25:18] <Tom_itx> just drop it off the next time you're in the US :)
[15:25:59] <Tom_itx> you could always repost it if it wasn't what you wanted
[15:26:23] <archivist> that rotary would fit on my horizontal mill I think
[15:26:30] <Tom_itx> is it within driving distance?
[15:27:36] <andypugh> This is quit enice: http://www.ebay.co.uk/itm/ENGINEERS-QC30-INT-TENTHSET-BORING-HEAD-/390441728325
[15:27:53] <andypugh> Tom_itx: The whole UK is within driving distance, but I don't have a car
[15:28:13] <archivist> about same distance for me or andy to drive to it, Im may be a bit nearer, may even get a payed for trip past it
[15:28:24] <andypugh> And strapping that to the back of my bike would be a challenge.
[15:28:38] <Tom_itx> hitch a ride with archivist
[15:28:39] <archivist> you can borrow a car or three!
[15:28:51] <Tom_itx> then you can argue who will own it
[15:29:23] <andypugh> Jymmm: Still looking for wierd tent pegs? http://www.ebay.co.uk/itm/TUNGSTEN-CARBIDE-TUBE-040-OD-x-012-ID-x-6-L-EDM-/380389335876
[15:29:44] <archivist> rucksack and loosen the straps so weight in on seat behind
[15:30:18] <andypugh> A friend of mine brought his Suzuki GP100 back to London on the back of his Triumph Bonneville, strapped to his back.
[15:31:21] <archivist> I got a tv brought here on the back of a honda 50 in about 1967
[15:31:39] <cradek> I've moved a tuba on a bicycle
[15:31:41] <archivist> still in the loft
[15:32:17] <jthornton> I carried a 4'x8' sheet of plywood on my honda 50
[15:32:46] <andypugh> A friend of mine moved a V8 on his bicycle.
[15:32:55] <archivist> honda 50 abuse++
[15:32:59] <andypugh> It was the small-blck Chevy 3.5
[15:34:41] <archivist> one of the few bikes you can unseize on the road side as long as you have a few tools and a bit of wet and dry
[15:35:23] * skunkworks wonders what wet and dry is
[15:36:13] <archivist> fine silicon carbide sandpaper
[15:36:20] <pcw_home> I remember the top speed in 1st was about 5MPH on the Honda 50
[15:37:00] <archivist> hands up who has not owned a honda 50, probably the smaller set
[15:37:11] <JT-Shop> I brought a yahama 250 back from North Carolina to Missippi with the font wheel strapped to the rear bumper
[15:37:26] <JT-Shop> of my Nova
[15:37:32] <cradek> mine was a kawasaki 175
[15:37:39] <andypugh> I have not owned a honda 50. I had a Puch 50, and a Honda 100
[15:37:58] <andypugh> For some reason I preferrd the Pugh 50 to the Honda. :-)
[15:38:02] <JT-Shop> the honda 50 super sport was my first bike
[15:38:17] <cradek> it would go 50mph which was good because it let you get out in front of all the blue smoke
[15:38:23] <JT-Shop> I proptly broke the tail light doing a wheele in the school yard
[15:38:47] <cradek> the kick starter didn't work so I had to push it every time
[15:39:11] <JT-Shop> 175 twin?
[15:39:30] <cradek> pretty sure it was 1 cylinder 2 stroke
[15:40:06] <archivist> pronounced two smoke
[15:40:38] <JT-Shop> my friend had a yahama 100 twin it was prett fast compaired to my honda 50
[15:40:57] <cradek> http://p1.bikepics.com/2006%5C04%5C09%5Cbikepics-559127-320.jpg
[15:41:15] <cradek> or similar ... it's been a long time
[15:41:24] <cradek> I remember the leg burner
[15:41:29] <JT-Shop> on and off road
[15:41:40] <JT-Shop> keeps you warm in the winter
[15:41:53] <cradek> don't be silly - it doesn't start in the winter
[15:42:14] <JT-Shop> http://www.youtube.com/watch?v=FxnoS2HD598
[15:44:35] <mazafaka> http://p1.bikepics.com/2006%5C04%5C09%5Cbikepics-559127-320.jpg <-- what is its weight?
[15:44:48] <JT-Shop> maybe you didn't shake it properly in the winter
[15:45:05] <cradek> 250 lb maybe?
[15:45:24] <mazafaka> it's about 110 kg?
[15:46:13] <mazafaka> it's frame is steel, right? And so do the rims
[15:46:44] <mazafaka> it nevertheless offers more than any 160-180 kg bikes
[15:46:47] <JT-Shop> I like the older on/off road bikes they had a lower seat height than my honda 200XL does
[15:49:58] <gene77> I just had an odd one, I wanted to stop & take a measurement so at the end of the retrace I grabbed the feed oride and slid it to 0, followed by the spindle
[15:51:29] <gene77> The measurement looked ok, so I put the sliders back but no action. I hit stop and restarted the run, no spindle, and I had to restart linuxcnc to get my spindle back.
[15:51:41] <gene77> 1 in a 1000 maybe?
[15:54:14] <gene77> I'd call that a nilmerg :)
[16:05:32] <Jymmm> andypugh: Thanks, I have some 1/4" thick wall SS tubing I'm going to try for tent pegs. But... I was also looking for/make a collapsple pole; thos Ti might do the trick, I also JUT picked up something else that might work with some modification =)
[16:05:57] <Jymmm> JUST
[16:22:35] <Connor> Jymmm: Whatcha making a collapsible pole for?
[16:22:53] <Tom_itx> he needs a walking cane?
[16:23:38] <Jymmm> lightweight, portable antenna mast
[16:32:08] <gene77> humm, sounds like me!
[16:32:49] <Jymmm> gene77: ???
[16:32:52] <gene77> silly Q, is there such a beast as a 3.5mm bristol wrench?
[16:34:33] <gene77> yeah, jymmm I use a cane if I have to go more than 50 yards at a time.
[16:36:02] <gene77> andypugh; I have that screw made except for the allen or bristol socket
[16:36:05] <Jymmm> gene77: Oh, heh. I actually do have a heavy wooden cane in the back of the car, but it's primary purpose isn't orthopedic =)
[16:36:45] <gene77> chuckle, emergency skull buster I assume :)
[16:37:19] <gene77> Now, how about that 3.5mm bristol wrench?
[16:37:46] <andypugh> I haven't ever seen a Bristol socket except in pictures
[16:38:19] <micges> andypugh: hi
[16:38:29] <Jymmm> gene77: "No, of course not". But, if you happen to ever be needing to, oh I don't know, let's say entr a courthouse to pay a ticket, or need to hop on a plane, medical devices are exempt from prohibited items =)
[16:38:41] <gene77> Humm, I was under the impression that was a brit invention. But it isn't in my #27 machinery handbook either
[16:39:02] <andypugh> http://en.wikipedia.org/wiki/List_of_screw_drives
[16:39:39] <DJ9DJ> gn8
[16:42:40] <gene77> I see its there, but no links to any actual, you could make one from the specs specifications.
[16:44:08] <gene77> There is also no mention of this 'WOBBULATOR' method of broaching, anybody have a link?
[16:44:21] <toastydeath> rotary broaching
[16:49:26] <gene77> There is also no mention of this 'WOBBULATOR' method of broaching, anybody have a link? Found one looks expen$ive
[16:50:04] <gene77> Not to mention my mill only has 150 lbs of push :(
[16:50:39] <gene77> Well, I suppose I'd better go see what Dee wants for dinner.
[16:50:44] <gene77> bbl
[17:09:13] <gallenat0r_> What CAM app do you use for lathe?
[17:09:46] <andypugh> I maninly don't
[17:10:19] <Tom_itx> JT-Shop uses ngcgui
[17:10:26] <andypugh> Both JT and myself (and probably others) tend to use subroutines.
[17:10:32] <Tom_itx> it's installable within linuxcnc
[17:10:41] <andypugh> For one-offs it's simpler.
[17:10:53] <Tom_itx> i agree on the lathe
[17:11:06] <Tom_itx> we did most of our lathe stuff mdi then saved it
[17:11:17] <andypugh> This is my Lathe screen: http://www.bodgesoc.org/lathe/lathe.html
[17:11:44] <andypugh> I just dial in target X and Z, cut and feed, and press the button for the operation I want.
[17:11:53] <andypugh> It works a treat for one-offs.
[17:11:57] <Jymmm> andypugh: You made a shoot em up module?
[17:13:35] <andypugh> What I want to do is the same thing as tabs. Each tab has a picture of the op, with dimensions you can type in, then press the button.
[17:13:55] <Tom_itx> nice
[17:14:15] <andypugh> Partly because I tend to forget details like whether thread depth is diameter or radius, or where the chamfer/radius ops start from.
[17:14:55] <andypugh> But I have other things to do first.
[18:01:54] <Nick001-Shop> can the end program be saved for repeat jobs?
[18:02:48] <Tom_itx> rephrase that
[18:03:24] <Tom_itx> oh on the ngcgui? yes
[18:03:36] <Nick001-Shop> the program that you generate - can it be saved?
[18:03:38] <Tom_itx> you combine the pieces and save them as a file
[18:03:51] <Tom_itx> that's the whole idea
[18:04:17] <Nick001-Shop> ok - have to try it out on the hardinge
[18:05:01] <Nick001-Shop> does it have a multi pass turn cycle?
[18:05:27] <Tom_itx> you'd have to ask JT-Shop or andypugh
[18:05:54] <Tom_itx> you can make your own and save them as well
[18:05:59] <JT-Shop> ask me what?
[18:06:08] <Tom_itx> about ngcgui
[18:06:17] <JT-Shop> ok, ask away then
[18:06:18] <Nick001-Shop> multi pass turn cycle
[18:06:35] <JT-Shop> for OD turning?
[18:06:45] <andypugh> Nick001-Shop: ngcgui creates a G-code file. My code does not create a G-code file, it passes parameters to predefined subroutines. Both split the moves into as many passes as the cut requires based on the parameters given
[18:07:24] <JT-Shop> Nick001-Shop> can the end program be saved for repeat jobs? ngcgui yes
[18:08:21] <Nick001-Shop> will have to get into it after I get my new project going
[18:08:23] <Nick001-Shop>
[18:09:02] <JT-Shop> Nick001-Shop: http://gnipsel.com/shop/hardinge/hardinge.xhtml
[18:09:34] <JT-Shop> I do 95% of my ops using ngcgui
[18:09:52] <JT-Shop> sometimes I use gedit for fun
[18:10:45] <JT-Shop> Nick001-Shop: you can concatanate several ops to create a part from start to finish
[18:11:01] <Nick001-Shop> site has expanded from last I looked
[18:11:12] <JT-Shop> which site?
[18:11:21] <Nick001-Shop> yours
[18:11:34] <JT-Shop> oh, I'm always adding as I discover things
[18:12:22] <JT-Shop> bbiab
[18:12:38] <Nick001-Shop> I'm still hand writing g-code as I've always done - was only way with these old cnc's
[18:18:44] <andypugh> I get this a lot. It's not helpful: http://imagebin.org/221587
[18:19:21] <Nick001-Shop> I was asking about multiple spindle control in linuxcnc - drilling and rigid tapping spindles - each on its own slide
[18:20:12] <andypugh> I think you will hit G-code limitations more than LinuxCNC limitations. G-code assumes one spindle, speed set by S
[18:21:46] <andypugh> Any suggestions what is wrong in that sceeenshot? My DN2800 does the same thing
[18:22:00] <andypugh> Oh, btw JT-Shop That's the NCBox
[18:22:08] <Nick001-Shop> is there a way of putting it into an M-code with the calls in there and ported out of parport at different locations
[18:22:35] <andypugh> Yes, and you can use analogue output pins (G-code to HAL analogue, that is)
[18:23:13] <Nick001-Shop> any links to this info?
[18:23:49] <andypugh> You want a link back to this IRC conversation?
[18:24:15] <Nick001-Shop> no - analogue output pins (G-code to HAL analogue, that is)
[18:24:43] <andypugh> http://www.linuxcnc.org/docs/html/gcode/m-code.html#sec:M67-Analog-Output
[18:26:09] <Nick001-Shop> can there be multiple M67's ?
[18:26:18] <andypugh> Also see http://www.linuxcnc.org/docs/devel/html/remap/structure.html for even more ways to peel a felid.
[18:26:54] <andypugh> You can have 16 channels I think. Perhaps 8. More if you change a stupidly low number and recompile.
[18:28:20] <Nick001-Shop> that will keep me reading for a while -)
[18:29:26] <andypugh> You have M31, M32, M33 and M41, M42 etc available to re-map for your extra spindles. Most of M5 is taken, though
[18:34:38] <Nick001-Shop> would I call like M200 and have the hal pins inside of it calling pwmgen, direction and encoder pins
[18:36:03] <Nick001-Shop> to drive an H-Bridge card to drive a particular spindle motor
[18:37:10] <andypugh> Define "it"
[18:37:59] <andypugh> You could, but that isn't very G-code
[18:38:06] <andypugh> Depends what you want to do.
[18:38:26] <andypugh> You could make M100 = spindle 2 on at 3000 rpm.
[18:39:09] <andypugh> Actually, you could probably use M100 1 3000 to set spindle 1 to 3000, and M100 1 0 to stop it.
[18:39:50] <Nick001-Shop> right and then call a movement on the slide for that spindle - joint 1-8
[18:39:57] <andypugh> The bash script called would just halcmd setp pwmgen.1.value 3000
[18:40:35] <andypugh> Sorry, probably halcmd setp pwmgen.%1.value $2
[18:41:07] <andypugh> (with the correct syntax to actually work, bash scripting is an unopened book to me)
[18:43:25] <Nick001-Shop> using a 2000 line encoder on that spindle - can linuxcnc handle that directly or would I need to use a mesa like card
[18:44:08] <andypugh> Nick001-Shop: It can handle it directly. At low speed
[18:44:31] <Nick001-Shop> like how slow?
[18:44:34] <andypugh> By low, I mean hundreds of rpms
[18:45:16] <Nick001-Shop> ouch - need 900-2000 rpm from each spindle
[18:46:01] <Nick001-Shop> tapping would be at 600 - 1200 rpm
[18:46:57] <cpresser> 600 rpm = 10rps = 20k pulses/sec that might be to fast for the parallel-port
[18:47:10] <andypugh> 2000 rpm * 8000 counts / 60 seconds is 250kHz. That's well into Mesa/Pico territory. No choice.
[18:48:45] <Nick001-Shop> what mesa cards would i need to do this? 8 spindles on 8 slides and 1 rotary positioning spindle
[18:49:02] <andypugh> Servo or Stepper?
[18:49:15] <Nick001-Shop> servos
[18:49:41] <Nick001-Shop> just dc motors with encoders
[18:51:16] <andypugh> Probably a 5i23 and two 7i48s. But a 5i25 and two 7i77s is an option. You might even manage with 5i23 and one 7i65
[18:51:55] <andypugh> Ah, hang on, you need 16 analogue voltages?
[18:52:10] <andypugh> (8 servos and 8 spindles)
[18:52:26] <Nick001-Shop> what will do the best job - only slightly cost conscience
[18:53:07] <andypugh> How will you drive the spindles? Anlogue to VFD?
[18:53:17] <andypugh> What type of motor?
[18:53:49] <Nick001-Shop> dc motors - 24vdc 1.8 amps
[18:53:58] <andypugh> That's the spindles?
[18:54:33] <Nick001-Shop> Per unit has 1 spindle and 1 moter driving a ballscrew
[18:55:07] <Nick001-Shop> 8 units and 1 rotating or indexing spindle
[18:55:50] <Nick001-Shop> each spindle has its own drive motor
[18:56:12] <andypugh> In total, how many DC motors (DC brushed, DC brushless, Induction) at what voltage and current, how many encoders and how much IO?
[18:57:09] <andypugh> Bear in mind I don't work for or have any special knowledge about Mesa kit. I just know what I have picked up here and using the stuff that I have.
[19:04:47] <Nick001-Shop> 17 motors total , 17 total encoders - motors 16 about 24vdc @ 2 amps - 1 larger motor for the indexer
[19:05:47] <Nick001-Shop> possibly a brake for the indexer to hold position
[19:08:40] <Nick001-Shop> I'm going with brushed motors for now because they're plentiful
[19:11:27] <Nick001-Shop> hoping to drive motors with H-Bridge cards
[19:13:25] <andypugh> Does this link work?
[19:13:27] <andypugh> http://tinyurl.com/d99uws8
[19:15:45] <Tom_itx> goes to gmail
[19:16:01] <andypugh> Nick001-Shop: Sounds like a job for 3 x 6-axis cards and a 4-port FPGA card, so probably 3x7i48, 1 x 7i37TA and a 5i22
[19:17:30] <andypugh> But I think Mesa might have a low-power version of the 8i20 in the pipeline, which might eliminate the analogue stages.
[19:18:09] <Nick001-Shop> any idea when it would be ready?
[19:18:42] <andypugh> None at all. This is a customer-rumour, not insider-information
[19:19:02] <andypugh> I just spotted the 7i30
[19:19:48] <Nick001-Shop> the 5i22 plugs into the PCI slot and the rest are daughter cards?
[19:20:01] <andypugh> 5i22 + 4 x 7i30 gives you PCI-slot-to-motor
[19:20:33] <andypugh> 7i30 is a quad H-bridge that plugs into the PCI cards.
[19:22:01] <andypugh> 5i22 + 4 x 7i30 is 16 of your motors + encoders. You would then need either a second PCI slot or you could consider a 7i43 on the parport for everything else.
[19:22:52] <micges> just mentioning: 7i40 have more amps than 7i30
[19:22:59] <Nick001-Shop> I have 5 PCI slots on these mb's
[19:23:44] <andypugh> micges: I think he only wanted 1.8A
[19:24:08] <andypugh> 7i30 is $90 for four channels, sounds a bargain
[19:24:10] <micges> ah ok
[19:25:11] <Nick001-Shop> how many amps on 7i40 card
[19:26:08] <andypugh> 2 x 5i20 probably makes more sense than 1 x 5i22 + something else then.
[19:26:31] <andypugh> Nick001-Shop: www.mesanet.com
[19:27:42] <Nick001-Shop> have it - will look at it later almost time to go home -)
[19:27:55] <andypugh> 2 x 5i22 + 8 x 7i39 for a sweet 16 x brushless motor setup :-)
[19:28:23] <micges> heh
[19:28:40] <Nick001-Shop> what would be for brushed motors
[19:29:06] <andypugh> 7i30 is for brushed
[19:29:45] <andypugh> Be careful not to make PCW too rich, though. He might retire.
[19:31:36] <Nick001-Shop> I need a lot of other stuff - like resolver cards if I can find that fellow in Atlanta to see how he made out
[19:32:08] <Nick001-Shop> would be cost effective vs the pico way
[19:32:35] <andypugh> Resolver?
[19:32:39] <WillenCMD> how does one get he glade components to show up on a sim installed system
[19:33:08] <andypugh> Nick001-Shop: Which chap in Atlanta?
[19:33:57] <andypugh> WillenCMD: I am surprised that they don't
[19:34:23] <WillenCMD> me also
[19:34:41] <WillenCMD> im in the process of making a hal component gui
[19:34:43] <andypugh> FWIW I don't bother with sim systems, I run in VMS and simply ignore the RT errors when latency gets over 1 million. (and it does)
[19:35:02] <andypugh> Sorry, VMs not VMS
[19:35:15] <andypugh> ie, Virtual Machines
[19:35:17] <WillenCMD> thats what i ususally do
[19:35:30] <Nick001-Shop> I have other machines with resolvers that need to be converted
[19:35:53] <Jymmm> andypugh: Uh huh, you KNOW you really meant VMS =)
[19:37:28] <Nick001-Shop> andypugh - I think his name was ssl
[19:37:43] <andypugh> I have never knowingly used VMS. But who knows what I was using during my PhD when I was using fortran on a mainframe via a storage-screen terminal
[19:38:20] <andypugh> Nick001-Shop: What was he using? I know a fair bit about Resolvers and LinuxCNC
[19:39:49] <andypugh> I am using resolvers on my own machine.
[19:39:53] <skunkworks__> andypugh: have you done anything more with the arduino resolver interface?
[19:40:12] <Nick001-Shop> He redid a Hardinge HCNC with mesa cards
[19:40:23] <andypugh> skunkworks__: I converted it to fast serial last weekend, rather than emulated quadrature, which is a lot more elegant
[19:40:58] <Nick001-Shop> He was having issues of some kind with the cards
[19:41:13] <skunkworks__> neat - is it still 1000 counts per rev? also - when I played with it - it didn't seem to be linear throughout the rotation.
[19:41:22] <andypugh> Nick001-Shop: I also wrote the driver for the Mesa 7i49 Resolver/servo card, so if there are problems I am the one to talk to. If you get one I guarantee I will make it work.
[19:42:08] <skunkworks__> (and I still have not played with the accupins...)
[19:42:09] <andypugh> Nick001-Shop: He needs to tell me and/or PCW if there are problems.
[19:42:39] <Nick001-Shop> would be cost effective to replacing working resolvers with encoders that don't last as long
[19:42:54] <andypugh> skunkworks__: I haven't checked ilinearity. It is something that could be tweaked (for example by fudging the arctan table)
[19:43:24] <andypugh> Resolvers are much more satisying than incremental encoders.
[19:43:27] <Nick001-Shop> This was a couple of months ago and I haven't seen hin here lately
[19:44:10] <Nick001-Shop> I have resolvers that are still working after 30 years of use
[19:44:39] <skunkworks__> encoders shouldn't go bad... (as long as they don'
[19:44:40] <andypugh> Well, he has presumably either got it working and is making chips, or he has trashed the lot, fitted encoders and gecko step-dir drives and is using Mach
[19:44:45] <skunkworks__> t get crap in them)
[19:45:17] <andypugh> Yes, but you can use a resolver in chicken soup and it will still work perfectly.
[19:45:26] <Nick001-Shop> II rather think he got it working somehow - I hope
[19:45:45] <skunkworks__> yes
[19:46:08] <skunkworks__> (if the machine has resolvers - I would use them) ::)
[19:46:18] <Nick001-Shop> These machines throw out aan oil mist that gets into an encoder
[19:47:01] <Nick001-Shop> and I'v replaced 2 of them already in the 1 machine
[19:47:41] <andypugh> The trouble with Resolvers is that they are not the sort of thing you will buy to replace encoderss with, those things are expensive
[19:47:59] <Nick001-Shop> Put the resolver back in the spindle and used a pico adapter for it
[19:49:01] <andypugh> Going back to quadrature seems a little retrograde.
[19:49:05] <skunkworks__> heh
[19:49:07] <Nick001-Shop> machines came with them and they still work - unlike the Allen Bradley controls on them
[19:49:11] <skunkworks__> old school....
[19:50:42] <andypugh> And skunkworks already has an Arduino on the machine. And my Arduino code. And (IIRC) one of my Resolver boards. He could easily connect up a spindle resolver to the Arduino and use 2 channels for spindle and one for temperature.
[19:51:32] <skunkworks__> I think I have 3 - or maybe 2
[19:52:03] <andypugh> Then, with the serial mod, and a new firmware for his Mesa cards, he could measure spindle temperature at 1kHz, just in case :-)
[19:52:14] <skunkworks__> heh
[19:54:45] <Nick001-Shop> Time to shut the shop down and go home - be back later on the other computer
[20:00:43] <andypugh> Is the Allegro AT667 really the only metal-detecting Hall sensor on the market? (ie, PCB-mount component with internal magnet and Hall device)
[20:01:32] <andypugh> <looks at djdelorie as somone who might know his components>
[20:01:38] <Jymmm> prox?
[20:01:51] <andypugh> Hmm, ATS667 I mean
[20:02:06] <Jymmm> are you looking for priximity sensor or ?
[20:02:38] <andypugh> Jymmm: Effectively, yes, but in a 4-pin SIP not a 2" long threaded housing
[20:03:00] <Jymmm> ah
[20:03:05] <Tom_itx> http://sensing.honeywell.com/products/magnetic_position_sensors?Ne=2308&N=3094
[20:03:09] * Tom_itx looks at andypugh
[20:03:27] <andypugh> I actually now have 4 of the ATS667, but couldn't find a UK source and imported from HK)
[20:04:41] <Tom_itx> http://www.hamlin.com/technical-detail-hall-sensor.cfm
[20:04:49] <Tom_itx> haven't seen any of theirs
[20:05:19] <andypugh> Tom_itx: I think that the top two detect magnetised targets. The ATS667 detects ferromagnetic targets.
[20:06:06] <Tom_itx> i wonder what i had
[20:06:09] <Tom_itx> it was allegro
[20:06:13] <andypugh> Tom_itx: Yes, the Hamlin one is the right sensor, wrong package
[20:06:28] <Tom_itx> they may have different packaging
[20:06:28] <andypugh> Tom_itx: Probably ATS667
[20:07:00] <skunkworks__> I have some ats667's that I need to play with too
[20:07:22] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/temp/hall/HallSensor2.jpg
[20:07:41] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/temp/hall/Hall_Sch.png
[20:07:49] <Tom_itx> mmm doesn't say which one
[20:08:00] <andypugh> There is nothing wrong with it, it's a god device, which makes it all the stranger that there appears to be no alternative on the market
[20:08:24] <Tom_itx> it was for current sense i believe
[20:08:38] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/temp/hall/Hall2.jpg
[20:08:47] <Tom_itx> that was fun to cut
[20:09:35] <andypugh> Tom_itx: That looks different. That's a normal Hall (detects magnetic field). The ATS667 has its own internal magnet and detects the change in field when metal passes by
[20:10:23] <Tom_itx> it was for a windmill current sense circuit
[20:17:36] <WillenCMD> today i set up up another successfully machine with using only hal components, this one was by far more complicated than the first
[20:19:31] <WillenCMD> using the loadrt list basically has every logic component in it, i think im using like 6 mux2, 2 mux4, 6 mult, 5 sum2's, 15 nots, 12 ors and dozens more
[20:21:13] <andypugh> WillenCMD: At that point, you need to consider writing a custom comp
[20:21:26] <WillenCMD> i know, im trying right now
[20:21:39] <WillenCMD> i printed off every hal component
[20:22:41] <WillenCMD> i have almost completed my servo-stepper tuning interface, that allows you to change real time pin data & saves it to your hal file
[20:23:48] <Tom_itx> andypugh, see anything here: http://www.rohm.com/products/lsi/sensor/hall_sensor/ic/?gclid=CJG6k4nLqbECFWVvTAodR1EA_g
[20:23:57] <WillenCMD> it graphs the position command, encoder position, and velocity, makes tuning a breeze you can see oscillation in the graph and adjust accordingly
[20:24:10] <andypugh> Neat
[20:25:06] <andypugh> Tom_itx: No, they all have an mT threshold.
[20:26:04] <WillenCMD> my next goal is to make a graphical hal configure gui, that is similar to visual robotic programing. Putting hal comps as puzzle pieces allowing you to attach accordingly, it will then generate a hal file
[20:26:41] <andypugh> You will join a group of several in that quest.
[20:26:57] <WillenCMD> whats so hard about it?
[20:27:26] <cradek> the last 20%
[20:27:30] <Tom_itx> andypugh wasn't there an eagle thing that was supposed to do that?
[20:27:34] <andypugh> Folk do keep trying. Search the website for Graphviz, Crapahalic and Eagle
[20:28:13] <archivist> I should mod my database erd program to do it as well :)
[20:28:15] <andypugh> Can I change my answer to match cradek's?
[20:29:16] <WillenCMD> does graphiz work?
[20:30:09] <andypugh> Graphviz does, it is a well established package. Whether it works usefully for HAL is an open question
[20:30:23] <WillenCMD> gotcha
[20:30:26] <WillenCMD> ill check it out
[20:30:41] <WillenCMD> i did manage to get some of the glade components to show up
[20:31:16] <WillenCMD> in this ubuntu 12.04 sim instal
[20:32:17] <pcw_home> andypugh: I have not heard from anyone with a resolver/7I49 issue
[20:32:24] <andypugh> I think Graphviz is OK at HAL->diagram and Eagle is OK at diagram->HAL. And Crapahalic (which I hate the name of, by the way) is equally poor at both, but does try.
[20:33:07] <andypugh> pcw_home: Good. With LinuxCNC, or so you not know?
[20:34:01] <andypugh> Making it look like a canonical encoder was the "not much thinking" approach, but seems like it might not ne optimum.
[20:36:23] <Tom_itx> andypugh, ? http://www.melexis.com/Hall-Effect-Sensor-ICs/Special-Purpose-Hall-ICs/MLX90217-3.aspx
[20:37:44] <andypugh> Tom_itx: Aha! That's actually better than the Allegro one.
[20:38:14] <Tom_itx> there's not many of them out there
[20:38:19] <pcw_home> Well reading back to what Nick001-Shop said if someone had troubles with our hardware I would think we would hear about it
[20:38:37] <andypugh> But you have to add your own magnet, so I just changed my mind :-)
[20:38:42] <WillenCMD> i like to keep that stuff secret
[20:39:04] <Tom_itx> andypugh i thought it was on the back side
[20:39:23] <Tom_itx> maybe not
[20:40:27] <Tom_itx> so get a small magnet
[20:41:01] <andypugh> And I could have bought that from RS, after I would be finished the time machine: http://uk.rs-online.com/web/p/hall-effect-sensor-ics/6843301/
[20:42:24] <andypugh> Maybe the point I am missing is that they all work for my application if you add your own magnet?
[20:42:52] <Tom_itx> the allegro one has the magnet built in?
[20:43:07] <andypugh> Yes. Mine keep sticking together
[20:43:11] <Tom_itx> mmm
[20:43:45] <andypugh> I just picked up an AA battery with one
[20:44:23] <Tom_itx> http://unitednuclear.com/index.php?main_page=product_info&cPath=70_71&products_id=255
[20:44:29] <Tom_itx> stick a magnet on it
[20:44:43] <Nick001> andypugh - he was having to update something to got resolvers working properly and I lost track of what waas going on. He was also having tach problems which is common on that machine.
[20:46:21] <andypugh> There is good quailty velocity information from the resolvers at the 7i49, but getting that as a voltage to the drives is non-trivial
[20:51:04] <djdelorie> andypugh: sorry, don't know. Was AFK too
[20:52:10] <andypugh> Sorry to drag you back :-
[20:52:57] <djdelorie> been an AFK day. made some fudge, worked on the southbend, cleaned the porch...
[20:53:16] <djdelorie> still haven't finished the inner control loop conversion for the controller boards, though...
[20:54:33] <andypugh> The good thing about a hobby is that you can work on the bits you fancy working on, or none at all. This is why I keep turning away paid work.
[20:55:35] <djdelorie> well, I have a special project that I need to do, and it requires a CNC machine
[20:55:52] <archivist> I dont get enough paid work :)
[20:56:11] <WillenCMD> i work for free but wish i was paid for it
[20:56:23] <WillenCMD> but i work for my dad still so...
[20:57:08] <Tom_itx> if i thought i could support it, i'd have a large cnc
[20:57:33] <Tom_itx> but keeping it a hobby is good
[20:57:33] <WillenCMD> actually funny but horrible story, last weekend i was submitting a resume to an employer and i must of some how printed it to the work printer and not realized it...
[20:57:49] <WillenCMD> lets just say that morning
[20:58:10] <WillenCMD> wasn't the best of mornings at work when they called me into the office holding my cover letter and resume to another employer
[20:58:25] <toastydeath> that sucks
[20:58:38] <toastydeath> everyplace I've worked so far I've given plenty of heads up i'm starting a job search
[20:58:40] <WillenCMD> i never make mistakes like that i was pissed
[20:58:44] <archivist> they should be offering a rise/raise
[20:58:46] <WillenCMD> oh i did also
[20:58:55] <WillenCMD> i told them last month
[20:59:03] <WillenCMD> but i guess they didn't take serious
[20:59:05] <toastydeath> ...then why did they call you into the office?
[20:59:09] <toastydeath> hah, morons
[20:59:33] <WillenCMD> they said they thought i was happy again, because the made me cnc supervisor(no pay raise though)
[20:59:54] <toastydeath> I've learned to never accept any additional responsibility without discussing pay firs
[20:59:57] <toastydeath> *first
[21:00:07] <WillenCMD> i laughed because i have been in charge un-officially for 3 years
[21:01:17] <WillenCMD> then they told me if i am going to quit they need to know now, and that i can't string them around like a yo-yo. Thats a direct quote
[21:01:31] <toastydeath> hahaha, did you laugh in their face?
[21:01:36] <archivist> a label does not help feed you
[21:02:04] <toastydeath> "I'm not quitting, I'm giving you a heads up that it is in my near-term goals to resign."
[21:02:06] <WillenCMD> archvist: true but i did update the resume accordingly :)
[21:02:51] <WillenCMD> i told them, i am waiting for the right job and i can't give them a definite date.
[21:04:05] <WillenCMD> im actually putting a business plan together for my business in hopes of maybe receiving some investors
[21:07:34] <andypugh> it's always worth turning up at work in a suit and tie and then taking the afternoon off :-)
[21:08:13] <andypugh> I am being patronised on #sparkfun. I am quite enjoying it.
[21:11:12] <WillenCMD> do i just write a halcomp in gedit and save as a .comp?
[21:11:20] <WillenCMD> then install it
[21:13:29] <Tom_itx> andypugh have you met flyback yet?
[21:13:34] <Tom_itx> he's a real piece of work
[21:14:26] <archivist> flyback has earned a kline :)
[21:14:36] <andypugh> WillenCMD: Yes, save as .comp then sudo comp --install it
[21:15:27] <ReadError> Tom_itx,
[21:15:35] <ReadError> i think he just got banned on efnet
[21:16:05] <ReadError> trollin too hard
[21:18:25] <tjb1> anyone here ever had to cut a laminate counter top to length
[21:19:05] <Tom_itx> i've had them cut
[21:20:30] <tjb1> Not sure how to do it
[21:20:41] <tjb1> Im gonna have to make 4 cuts
[21:20:44] <andypugh> tjb1: I think I have
[21:21:07] <tjb1> Throw tape down the cut line and cut from the backside with a fine tooth circular saw?
[21:21:24] <Tom_itx> carbide if you have it
[21:21:59] <WillenCMD> then file it to fit :)
[21:22:30] <tjb1> Arent the teeth on circular saw blades carbide?
[21:22:32] <Tom_itx> they cap em and smooth that off with a router
[21:22:37] <Tom_itx> not all of them
[21:22:51] <Tom_itx> if they're silver soldered on they are
[21:22:56] <tjb1> One guy at lowes said about putting the blade on backwards
[21:23:13] <WillenCMD> it can help prevent it from fracturing
[21:23:17] <Tom_itx> keep the blade low
[21:23:25] <WillenCMD> do you have fine tooth saw blade?
[21:23:28] <tjb1> Yep
[21:24:28] <WillenCMD> do you have a vertical milling machine with a pallet table? thats an easy way :)
[21:25:05] <tjb1> Yeah in the shed!
[21:25:33] <WillenCMD> behind the lawnmower?
[21:25:58] <tjb1> no behind the 5 axis mill
[21:26:11] <WillenCMD> oh that has to be a tight fit
[21:26:20] <tjb1> Got a dewalt 6.5" 40 tooth fine finish carbide tooth blade
[21:26:28] <WillenCMD> did you put a cross on the shed and make it a church, to avoid taxes?
[21:26:41] <tjb1> no its not put in the ground
[21:26:41] <WillenCMD> go there to worship everynight
[21:27:01] <tjb1> we have 2 - asimos working the shop at night
[21:27:34] <WillenCMD> thats it, everyone knows you have to have 3 to get anything done...
[21:27:49] <WillenCMD> one has to be the tool bitch
[21:28:03] <tjb1> no we have a 5 axis robot do that
[21:28:14] <WillenCMD> is the shed hiring?
[21:28:21] <tjb1> lol
[21:28:24] <tjb1> there is no shed
[21:28:28] <WillenCMD> i know
[21:28:35] <WillenCMD> we did good though
[21:28:43] <WillenCMD> built a hell of a fake shop
[21:29:10] <tjb1> yep yep
[21:29:21] <tjb1> http://www.amazon.com/DEWALT-DW9196-2-Inch-Precision-Framing/dp/B00697YQIU
[21:29:24] <tjb1> There she be
[21:30:08] <tjb1> Heh bought that blade a week ago and according to the dewalt website it has been discontinued
[21:30:09] <andypugh> Oh, who was asking about cutting Alu with a wood blade?
[21:30:43] <tjb1> Dunno
[21:31:22] <andypugh> I routinely cut through 1" Alu with my hand-held, cordless, circular saw using the original blade. No problems so far other than underpants full of swarf.
[21:31:44] <Tom_itx> that's gotta be a good feeling
[21:31:50] <tjb1> Going to be interesting cutting the backsplash
[21:32:00] <tjb1> Blade isnt big enough to do it without rotating the saw
[21:32:02] <WillenCMD> yes, but Andy you seem to accomplish more than the every day do-it-yourselfer
[21:32:19] <WillenCMD> you drill holes through carbide with your cordless drill
[21:32:35] <WillenCMD> :)
[21:33:58] <jdh> backsplash cuts fine from the back 7" circular saw
[21:50:14] <r00t4rd3d> painters tape
[21:50:22] <r00t4rd3d> no chipping
[21:50:50] <jdh> score with a knife
[21:50:59] <r00t4rd3d> score with your wife
[22:14:18] <r00t4rd3d> sketchup rocks
[22:14:47] <r00t4rd3d> with the phlatscript
[22:15:08] <r00t4rd3d> http://www.phlatforum.com/
[22:15:52] <r00t4rd3d> i can simply make accurate parts
[22:16:26] <andypugh> You can define actual sizes?
[22:16:31] <r00t4rd3d> yeah
[22:16:52] <r00t4rd3d> anally so
[22:16:52] <andypugh> I still find it unlikely that it actually "rocks"
[22:17:13] <r00t4rd3d> i can make parts with it and i cant with anything else so for me it rocks
[22:19:09] <andypugh> Ah, you reminded me of AutoCAD Mechanical 1998 vintage, where you would create a sketch to extrude, and it would tell you it lacked 7 constraints, and give you no clue at all which constraints were missing (and you couldn't use a sketch/profile unless it was fully constrained). It was like the world's least interesting logic puzzle, and mandatory.
[22:19:57] <toastydeath> hahahahah
[22:20:04] <WillenCMD> lol
[22:20:36] <andypugh> You laugh now. I had to design parts.
[22:21:30] <WillenCMD> im laughing because i can imagine how much of a pain that was
[22:21:30] <toastydeath> no, I laugh because I have had to use plenty of shitty modeling packages
[22:21:39] <toastydeath> i'm glad autocad mechanical wasn't one of them
[22:24:05] <andypugh> They threw it all away and made Inventor, and that is lovely. Then they dragged it back out of the skip and carried on with it, but in parallel to Inventor. (and I am sure that AutoCAD is better now)
[22:24:54] <toastydeath> i hated inventor
[22:25:04] <toastydeath> the packages i've liked so far are pro/e and solidworks
[22:25:09] <toastydeath> but i haven't used pro/e in a hot minute
[22:25:29] <Tom_itx> i think alot of packages beat acad for cad cam use
[22:25:55] <Tom_itx> i knew a guy way back when that used it along with nc polaris. i never understood why he liked it but he did
[22:26:02] <andypugh> I have almost no complaints about Inventor, other than that it is a nuiscance if you accidentally create an Imperial drawing and wish it had been in Metric. But it's no worse there than Aibre.
[22:26:18] <Tom_itx> http://www.ncpolaris.de/html/ncp_english.html
[22:26:28] <Tom_itx> i'm sure it's come a long ways since then
[22:27:15] <andypugh> That seems to be a CAM system, and claims to work with Inventor
[22:27:36] <Tom_itx> it was an add on for acad back then
[22:28:16] <Tom_itx> it worked but i sure didn't like it
[22:28:43] <andypugh> It is worth stressing that Inventor and AutoCAD are rather different (and Maya and Fusion are different again). They all do 3D modelling, but with rather different paradigms
[22:31:50] <toastydeath> i didn't like inventor because at the point i was using it, I was most practiced in pro/e
[22:32:01] <toastydeath> which beats the everliving shit out of inventor for features and speed of modeling
[22:32:28] <toastydeath> i've never used autocad for anything except drafting
[22:39:42] <andypugh> I have never used ProE.
[22:40:40] <andypugh> I have found something Inventor can't do, though, and it might be a fun test for ProE. I could _not_ get it to assemble a hexapod.
[22:40:42] <Tom_itx> how does it compare to rhino?
[22:41:14] <andypugh> Tom_itx: It doesn't. Very different applications
[22:41:51] <Tom_itx> i've never used either one
[22:42:03] <toastydeath> castings is a good place to go for shit that doesn't work well in most modeling packages, that only pro/e and catia can handle
[22:42:37] <toastydeath> but the speed and flexibility of pro/e was far greater than inventor
[22:42:51] <andypugh> The hexapod had hookes-roints at the top, and spherical feet with sliding square legs. It seemed unable to rotate the legs to solve the assembly.
[22:42:52] <toastydeath> *castings are
[22:43:16] <andypugh> What about castings?
[22:43:32] <andypugh> ie, what does ProE do that Inventor doesn't?
[22:44:49] <andypugh> It has a mould-design feature (which I have never used) which appears to go an awful lot further than split-plane definition, it seems to be able to design sliding parts automatically too,
[22:44:51] <toastydeath> radiusing on complicated revolved surfaces
[22:45:12] <toastydeath> some drilled holes on the same type of surface
[22:45:50] <andypugh> I have never had it fail to drill a hole, though sometimes it can be hard to define the hole.
[22:46:01] <toastydeath> I had a casting with 250+ features
[22:46:11] <toastydeath> in solidworks, and it couldn't place some of the things
[22:46:21] <toastydeath> and inventor is worse than solidworks for that
[22:47:00] <andypugh> You might end up having to create a web of points axes and planes to locate it in some situations, but I suspect that is fundamental geometry, not the package
[22:47:10] <toastydeath> ot
[22:47:13] <toastydeath> *it's the package.
[22:47:33] <toastydeath> both inventor and solidworks have types of features that they acknowledge cannot be made
[22:47:49] <toastydeath> which is why pro/e and catia are used in things like automotive and aerospace over solidworks and inventor
[22:48:04] <toastydeath> they don't handle importing geometry as well
[22:48:18] <Tom_itx> yeah, my friend went with catia in the end
[22:48:30] <Tom_itx> mostly i think because his vendors used it
[22:48:36] <toastydeath> moulds aren't that hard to make, they rarely have bizarre features
[22:49:05] <Tom_itx> but even that required an additional cam package
[22:49:36] <andypugh> Well, I work in Automotive, we appear to use Inventor to design factories, and Unigraphics to design cars.
[22:50:39] <toastydeath> unigraphics is on the same level as pro/e and catia
[22:51:10] <Tom_itx> boeing did alot of customization on catia for their purposes
[22:53:11] <andypugh> Anyway, time to sleep before the sun gets all the way up,
[22:53:25] <toastydeath> gn
[23:05:58] <Jymmm> Is there another alcohol base clear coat other than shellac?
[23:09:41] <WillenCMD> anybody know how to uninstall a halcomp
[23:22:27] <cpresser> WillenCMD: just delete the file. but most likely you just want to unload it :)
[23:23:12] <WillenCMD> cpresser: no i made the component
[23:23:16] <WillenCMD> just testing it out
[23:23:51] <cpresser> then just delete the file.
