[01:35:06] <zeeshan> hi PetefromTn_andro
[01:35:08] <zeeshan> what are you upto
[01:35:53] <PetefromTn_andro> Right now just chilling out enjoying some music til I fall asleep you?
[01:36:10] <zeeshan> hah
[01:36:12] <zeeshan> im eating too
[01:36:15] <zeeshan> planning to watch a movie
[01:36:23] <zeeshan> spent most of the afternoon pulling the engine out of the rx7
[01:36:37] <zeeshan> i've noticed as i get older, i don't enjoy working on cars as much
[01:36:47] <zeeshan> i dont get the satification i used to get back in the day
[01:36:52] <zeeshan> i get more satisfying from machining something
[01:37:26] <PetefromTn_andro> I found out the 5/16 champfered holes I machined into the prototype rail is the wrong size dammit lol
[01:37:48] <zeeshan> what are they
[01:38:26] <PetefromTn_andro> Well the holes were made to match another rail made by someone else the customer did not like
[01:38:35] <zeeshan> http://imgur.com/a/aZ3Qz
[01:38:46] <zeeshan> bigger im assuming?
[01:38:58] <PetefromTn_andro> I ASSUMED they were 8-32 but they are actually m4
[01:39:45] <PetefromTn_andro> So when I went to order the screws from McMaster Carr realized the heads are slightly larger
[01:39:46] <jdh> Pete:
http://www.ebay.com/itm/290772919340
[01:40:18] <zeeshan> 8-32 calls for .136 drill (#29)

[01:40:36] <zeeshan> m4x.7 calls for .1299
[01:40:38] <zeeshan> 3.3 mm drill
[01:40:40] <PetefromTn_andro> Yeah the holes are drilling and tapped correctly
[01:40:48] <zeeshan> oh
[01:41:04] <PetefromTn_andro> But the champfer for the countersink head is wrong
[01:41:23] <jdh> 83?
[01:41:47] <PetefromTn_andro> They are gonna be 8-32 but now I gotta machined the champfer different
[01:42:39] <PetefromTn_andro> Sae 8-32 is 82 degree and the head is larger
[01:42:49] -!- Servos4ever has quit [Quit: ChatZilla 0.9.90.1 [SeaMonkey 2.26.1/20140612173529]]
[01:43:13] <PetefromTn_andro> Larger than the 5/16 countersink I have.
[01:43:22] <jdh> off by a degree
[01:43:56] <PetefromTn_andro> I am just gonna do it manually with my drilling and 82 degree cs
[01:44:09] <jdh> metric is 90. much more reasonable number.
[01:44:14] <jdh> well, not number, but angle.
[01:44:15] <PetefromTn_andro> Drill
[01:44:30] <PetefromTn_andro> Agreed
[01:44:49] <jdh> it's a stupid number
[01:45:02] <PetefromTn_andro> It sucks because my holes came out perfect when I machined them.
[01:45:17] <jdh> for the sake of perfection,you should start over.
[01:46:03] <PetefromTn_andro> Now I gotta try to fix this one manually. It's just a prototype so I guess it's okay. Heads will just be .050 or so larger.
[01:46:40] <PetefromTn_andro> If I sell a bunch I will just order th e
[01:46:58] <PetefromTn_andro> Right screws and countersinks
[01:48:21] <PetefromTn_andro> Other than that it looks awesome and fits perfectly to the original receiver lines.
[01:50:53] <PetefromTn_andro> I sure hope people like them it would be nice to get a bunch of orders for em LOL

http://youtu.be/aFZxm09G87E. Love this song...
[02:08:28] <zeeshan> youre old school :D
[02:08:42] <PetefromTn_andro> I did not like the waterjet we used at the shop I worked in. Nasty dirty machine
[02:08:43] <zeeshan> do you like metallica?
[02:08:58] <PetefromTn_andro> Meh they're okay.
[02:09:45] <PetefromTn_andro> Funny thing is it may be old school but I just got this album for my birthday a couple weeks ago
[02:10:06] <PetefromTn_andro> Never heard any of these songs before.
[02:10:13] <Tom_itx> dark side of the moon is good
[02:10:26] <PetefromTn_andro> Yeah I have about Ll
[02:10:42] <PetefromTn_andro> All their albums over the years.
[02:11:19] <PetefromTn_andro> I think it's cool how they put Steve hawkings computer voice in that track
[02:13:41] <PetefromTn_andro> Just out of curiosity what was your machining strategy for making those flanges Tom?
[02:14:09] <Tom_itx> it was a long time ago
[02:14:25] <Tom_itx> i think i probably drilled a couple holes to clamp then profiled em
[02:14:39] <Tom_itx> at least that's what i'd do now
[02:14:57] <Tom_itx> maybe 3 or 4 bolts
[02:15:31] <PetefromTn_andro> So screws down to substrate and profile after clamping and drilling
[02:15:57] <Tom_itx> predrill/tap the sacrificial plate
[02:16:04] <Tom_itx> drill the holes
[02:16:09] <PetefromTn_andro> Sure
[02:16:14] <Tom_itx> and mill away
[02:16:26] <PetefromTn_andro> Simple really
[02:16:32] <Tom_itx> 3 would probably be enough
[02:16:34] <Tom_itx> bolts
[02:16:51] <jdh> I have some 0.010" plastic shim material I've used to keep the work off the sacrificial plate. Used the same plate lots of times.
[02:17:12] <Tom_itx> after while we'd just skin cut the plate
[02:17:13] <PetefromTn_andro> I'd probably do more for stainless but I am a pain in the ass LOL
[02:17:52] <PetefromTn_andro> Yeah I have a couple plates here used for stuff like that.
[02:18:24] <PetefromTn_andro> One was for that custom battery tray prototype I made for those guys.
[02:19:07] <PetefromTn_andro> Unfortunately I think they advertised them and jacked the price too high for any real interest to be garnered
[02:19:10] <Tom_itx> we're lucky enough to have plenty of scrap in town
[02:19:23] <Tom_itx> can get nearly any size plate we'd need
[02:20:10] <PetefromTn_andro> Apparently there are some good scrap metal places in knoxvegas but never been there yet
[02:21:05] <PetefromTn_andro> Started working on another design for the shooting competition guys yesterday Ajax
[02:21:27] <PetefromTn_andro> Had a bunch of guys request this part to be made.
[02:21:59] <PetefromTn_andro> Probably hear crickets once I make one and have them ready to sell hehe
[02:22:30] <Tom_itx> just say 'show me the money'
[02:22:34] <Tom_itx> then make em
[02:23:45] <PetefromTn_andro> Yeah I know but honestly most of those guys rarely bullshit me about things generally if they ask for it as long as the price is right they Wil l
[02:23:53] <PetefromTn_andro> Will buy it
[02:24:18] <Tom_itx> hardly worth making just one or two though
[02:24:43] <PetefromTn_andro> Those guys spend more money on precision air rifles than I spend on my house
[02:24:44] <Tom_itx> how many machine hours are in them?
[02:24:52] <Tom_itx> + setup time
[02:24:55] <Tom_itx> + programming time
[02:25:20] <PetefromTn_andro> Oh there's already like ten guys committed to ordering one or two
[02:26:13] <PetefromTn_andro> Right now I don't really have anything else worth talking about going on so I guess I will make them.
[02:26:39] <PetefromTn_andro> I could use one myself too lol
[02:27:28] <PetefromTn_andro> It has been hot and humid as he'll here all weekend
[02:27:38] <PetefromTn_andro> Hell
[02:28:43] <PetefromTn_andro> Well better get to sleep cya later guys.

[07:50:05] <starno> archivist: can you elaborate? I am new to the scene
[07:51:35] <starno> archivist: thick aluminum frame design, is the accurace not dependent on the quality of the ballscrews? How is machining capability quantified?

[07:58:45] <archivist> a machine for milling steel is far heavier and stiffer than a machine for wood
[07:59:46] <archivist> some ballscrews are less good than others so price affects accuracy
[08:00:08] <archivist> rolled v ground ballscrew
[08:02:08] <starno> archivist: so do you just look at and make a subjective judgement or are there some specs on these kinds of qualities to look out for?
[08:02:13] <archivist> you can use a smaller machine and take very small cuts and take more time or use a stronger machine for faster heavier cuts
[08:03:12] <starno> Im looking to machine aluminum as the hardest material, 30x40 working area
[08:04:09] <starno> is a 800W spindle capable of cutting aluminum? assuming the frame is robust enough
[08:04:53] <archivist> sure
[08:05:52] <starno> I see some 500W options as well. Does the power relate to speed or does it also have an effect on the depth of cut possible?
[08:06:49] <archivist> it takes power to get high rpm and depth of cut and cut per tooth per rev
[08:08:02] <archivist> cut per tooth per rev is the root value that defines all the other values
[08:08:21] <starno> are there any disadvantages to using a high powered spindle? like if I am cutting plastic do I want to switch it out for a different spindle?
[08:08:48] <archivist> just set a sensible rpm
[08:08:59] <archivist> and use the right cutter and feed
[08:09:18] <starno> ok, so I want to go as high as I can on power on the spindle assuming I have the budget
[08:09:41] <archivist> the spindle power is only fully used when taking a large cut
[08:10:28] <archivist> often your cutter may be to small to utilise that power
[08:10:58] <starno> do you think the 500W might be more suitable for me?
[08:11:27] <starno> im looking to make parts no greater than 30-40mm in depth
[08:12:20] <archivist> width or length maybe I doubt you will be milling that deep
[08:12:47] <starno> i want a batch production style setup so speed is somewhat important, however I will most likely be using a 2mm bit
[08:13:40] <archivist> with a small bit you need high rpm to get productive, that uses a lot of the power
[08:13:56] <starno> ah, ok, thats good to know
[08:15:10] <starno> do you have any suggested readings or guides on the speeds, depth of cut, cut per tooth, etc.
[08:15:32] <archivist> with a flimsy machine on climb milling they can grab and snap the cutter, you need a stiff machine and ballscrew with no backlash
[08:15:57] <archivist> there are many online speed/feed calculators
[08:16:06] <starno> are T-screws more prone to backlash?
[08:16:17] <archivist> T ?
[08:16:26] <starno> trapezoidal
[08:16:49] <archivist> yes much worse
[08:16:57] <starno> ok
[08:17:23] <archivist> but you can remove backlash with some contrivance
[08:17:35] <starno> do you have any photos of your setup?
[08:18:10] <archivist> I have a fugly mill and a lathe
[08:19:31] <archivist> this is the mill before I changed one of the screws to ballscrew

http://www.cnczone.com/forums/chinese-machines/138286-cnc-machine-ts-3040c-h80-2.html
[12:10:03] <kamakaze_> I have urgent problem because I have to move from Mach3 to linuxCNC and my machine don't move practically
[12:10:23] <jthornton> you might try posting on the forum... I never go to the zone too many ads to wade through
[12:10:53] <jdh> with mach3 to stepconf version 0.9 created by John Thornton
[12:11:05] <Jymmm> lol
[12:11:51] <Jymmm> I dont see any ads at all... yay ABP!!!
[12:11:52] <kamakaze_> I posted that problem to two forums I am using jthornton your script to convert settings
[12:13:05] <jthornton> the script does make some assumptions because mark3 does not have settings for drive timing IIRC
[12:13:25] amnesic_away is now known as amnesic
[12:13:57] <kamakaze_> ok - that might be reason - please help me to get that work - what I have to do that I can get timing correctly?
[12:14:48] <jthornton> is your drive listed here
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Drive_Timing
[12:17:59] <kamakaze_> It looks that not... I don't remember it - box is create by DONGDA - it is one of these china models. Can I get driver name from driver info or is it nesessary to open box?

[12:34:31] <jthornton> I have no idea what you have, sorry
[12:34:50] <jthornton> open your config in stepconf and see what the drive timing is
[12:35:31] <jthornton> try a larger number like 20000 for timings

[13:07:12] <jdh> are you using a real parallel port or a USB device?
[13:11:43] <kamakaze_> I am using real parallel port
[13:12:14] <kamakaze_> My understanding is that it does't work at all with USB device, but I can be wrong
[13:13:09] <kamakaze_> I could find any differense (I used only axis test (is that right way to test) if I add step time from 5000 to 10000 or 20000
[13:13:14] <kamakaze_> what can be wrong?
[13:13:30] <jdh> got the right pins?
[13:13:45] <jdh> was it working with the mock3 config?
[13:13:46] <kamakaze_> please help me - I have to get this work - if anybody can get my device work today I will pay 50 dollar via paypayl immediately
[13:14:00] <kamakaze_> it works with mach3 perfectly
[13:14:02] <jdh> heh... pay for stuff is a mach3 deal, not here.
[13:14:27] <kamakaze_> I know - it looks that nobody is not answering in forum too :(
[13:15:11] <kamakaze_> mach3 suck - it too expensive I try to move now to free linux based system, but it looks that without support I can't do it
[13:15:11] <jdh> patience.
[13:15:17] <cpresser> kamakaze_: i would suggest you write your pinout down on a sheet of paper. then start from scratch with stepconf
[13:15:29] <cpresser> test one axis at a time
[13:15:39] <jdh> yep
[13:15:45] <kamakaze_> so you guest that pinions are wrong?
[13:16:08] <JT-Shop> kamakaze_, try 20000 for all 4 timings
[13:16:15] <kamakaze_> but I checked then from mach3 setup that they are same
[13:16:23] <cpresser> my guess is that something is wrong. cant tell for sure. so a clean start might be the best option

[13:16:57] -!- jduhls has quit [Ping timeout: 245 seconds]
[13:17:08] <jdh> and stepconf by itself is pretty simple.
[13:17:23] <cpresser> most likely, that approach will be faster than tinkering around with the non-working config you have
[13:17:24] <jdh> make sure you get teh active high/low the same as your mach config.
[13:17:46] <kamakaze_> it is funny that it looks that nobody has same machine - I thought that this is best seller - cheap and work quite nicely
[13:18:05] <jdh> there are lots of them that look the same.
[13:18:08] <kamakaze_> I am quite sure about it jdh
[13:18:08] <JT-Shop> the converstion script should have gotten the pins and active high low correct
[13:18:23] <kamakaze_> I have to double check - thanks about this hint

[13:20:04] <jdh> LinuxCNC
[13:21:06] <kamakaze_> pins are exactly same - damn - I am already quite hopeless - I would like get rid of Windows XP, but it looks that I can't :(

[13:50:20] <kamakaze_> sorry where I can find that? Only pin17 settings what I found in xml was there two lines: <property name="pin17" type="string" value="xdir"/>
[13:50:23] <kamakaze_> <property name="pin17inv" type="bool" value="True"/>
[13:51:03] <ktchk> kamakaze_: stepconf
[13:51:40] <ktchk> kamakaze_: pinout table
[13:55:22] <kamakaze_> ktchk you was suggest to write down it - but where? I don't have any manual - only data what I have is working mach3 config and based on that it looks that all are same in linuxcnc
[13:56:03] <kamakaze_> so how I can know 'right' pins if these looks same than mach3 settings has
[13:56:21] <cpresser> kamakaze_: open the case, check with a multimeter
[13:57:36] <cpresser> it will help you a lot once you understand how everything is wired
[13:58:08] <ktchk> kamakaze_: run under application, cnc stepconf, stepper configuration wizard.
[13:58:28] -!- mle has quit [Ping timeout: 255 seconds]
[13:59:10] <cpresser> with a multimeter you can also check if the amp-enable and direction pins are working as intended
[13:59:24] <kamakaze_> I can do that with multimiter, but for me it looks that just timing is wrong because my motors make sounds when I press x +/- or y+/-, but it just don't move
[13:59:31] -!- anth0ny_ has quit [Quit: anth0ny_]
[14:00:01] <jdh> did you cahnge teh timing?
[14:00:05] <jdh> and try again?
[14:00:10] <cpresser> then open the datasheet of your drives. and check the timing
[14:00:13] <jdh> put 20k in for everything
[14:00:13] <kamakaze_> yes, but it looks that works totally same way
[14:01:36] <kamakaze_> I tested it now with everything 20000, but it sounds totally same - is sure that changes are in use without ending wizard first?
[14:02:45] <ktchk> kamakaze_: set everything end stepconf will generate config file then test again
[14:02:57] <kamakaze_> and one question - how I can know with multimiter is it step or direction?
[14:03:00] <cpresser> or: test within the wizard.
[14:03:22] <kamakaze_> so middle of wizard in axist test mode it don't have new settings yet?
[14:03:45] -!- sirdancealot [sirdancealot!~koo5@98.82.broadband5.iol.cz] has joined #linuxcnc
[14:04:02] <ktchk> kamakaze_: dir is + or 0 step is pulsating
[14:04:33] <cpresser> http://www.linuxcnc.org/docs/html/config/stepconf.html (Section5 -> "Test this axis" button)
[14:04:38] <kamakaze_> by the way I found bug in stepconfig code in line 575 there is if self.units or axname == 'a': leadscrew = 1./leadscrew
[14:04:57] <kamakaze_> and in this my case this leadscrew is 0 for a axis
[14:05:13] <kamakaze_> so I changed it to if self.units and axname != 'a': leadscrew = 1./leadscrew if axname == 'a': leadscrew = 0
[14:05:27] <kamakaze_> I suppose that this can't do any harm?
[14:06:13] <kamakaze_> thanks ktchk - I will check them if this is my last hope to get that work
[14:06:34] <ktchk> kamakaze_: use stepper configuration wan check everything
[14:07:06] <ktchk> kamakaze_: configuration wizard
[14:08:08] <kamakaze_> I have oscilloscope too so I will check signals with it
[14:08:11] <kamakaze_> maybe it helps
[14:08:46] <kamakaze_> is it possible that everything is just fine in setting, but linuxcnc just don't work with my controller - it is same what I have in settings?
[14:09:00] <ktchk> kamakaze_: not if the config file is wrong

[17:12:23] <Tom_itx> just set it all the way on
[17:12:41] <Tom_itx> i insulated mine a bit which helped the ramp speed

[17:17:09] <cpresser> its to thick, doesnt distribute nicely. and the parts dont really stick in the paste.
[17:17:23] <Tom_itx> yeah
[17:17:38] <Tom_itx> i get it cheap enough i just toss it after it sits so long
[17:17:45] <Tom_itx> keep it in the frig it will last longer

[17:19:47] <Tom_itx> that's what i've been using

[17:21:30] <Tom_itx> cpresser, are you using a stencil or applying with a syringe?

[17:22:50] <cpresser> but it features a QFP-100 package. with 0.5mm pitch. thats really small for a low quality stencil like mine
[17:22:51] <Tom_itx> i cut pockets in some plexiglas for the boards
[17:23:00] <Tom_itx> yeah
[17:23:41] <Tom_itx> ^^ makes stencil alignment easy
[17:24:16] <cpresser> actually, i did the same. lasercut 1.5mm acrylic. so the PCB has a thight fit :)
[17:24:28] <Tom_itx> qfn is pretty fine for plastic stencils
[17:25:42] <Jymmm> qfn???

[22:03:50] <roycroft> irrelevant at the moment :)
[22:03:54] <zeeshan|2> no

[22:06:12] <roycroft> i may use different cutter heads for different projects
[22:06:13] <zeeshan|2> so whats the point of a ball screw..
[22:06:14] <roycroft> i'll probably use a high speed spindle at first

[22:21:27] <CaptHindsight> zeeshan|2: how many lecture hours on average did you have per class per semester?
[22:21:39] <CaptHindsight> on engineering
[22:22:27] <zeeshan|2> for undergrad about 160-180 hours per class
[22:22:38] <zeeshan|2> 16 weeks, 3 hours per week
[22:22:50] <zeeshan|2> er
[22:22:52] <zeeshan|2> im on crack. lol
[22:23:05] <zeeshan|2> so 48-60 hours
[22:23:11] <zeeshan|2> not 160-180.
[22:23:31] <zeeshan|2> grad courses are like 50
[22:23:55] <zeeshan|2> the thing is once you account how much time you spend on projects, and labs, and tutorials, its close to 160 hours

[22:28:16] <zeeshan|2> take my advice and get an extra ball nut.
[22:28:16] <roycroft> the one i pointed to has free shipping
[22:28:27] <zeeshan|2> that way you can eliminate all the backlash
[22:28:33] <zeeshan|2> unless 3 thou backlash is acceptable
[22:28:34] <roycroft> just install them back to back?

[22:28:46] <roycroft> 0 backlash would be better
[22:29:06] <roycroft> because i'm sure there will be other places to introduce some error

[22:29:44] <roycroft> i'm still in the early design stage
[22:29:49] <roycroft> i'm not buying anything right now
[22:30:10] <roycroft> keep in mind that 10 minutes ago i was asking about r&p vs. ball screw
[22:30:38] <roycroft> and i'm still not 100% decided on either, but if the ball screw isn't going to have a whipping problem i would lean towards that
[22:35:17] <roycroft> well thanks for the input
[22:35:29] <roycroft> i'm going on holidays for a few days
[22:35:33] <roycroft> i have some things to ponder now
[22:35:57] <CaptHindsight> roycroft: what are you going to cut with it?

[22:36:59] <roycroft> on the wooden parts, though, i'll want to push it - time is money

[22:39:25] <CaptHindsight> you're not asking for much res
[22:39:40] <roycroft> 0.001" would be nice
[22:39:44] <CaptHindsight> you're on the edge of using a good belt drive
[22:39:46] <roycroft> but i don't think it's necessary for now at least
[22:39:57] <roycroft> 0.005" will do almost everything i want for now
[22:40:03] <roycroft> so i thought it a good design parameter
[22:40:34] <CaptHindsight> http://www.ebay.com/itm/Yaskawa-STF35230M-AC1L-BDB-Servo-Linear-Motor-57-25-Travel-Length-Encoder-/170987551281 if you want 0.0002 :)
[22:41:13] <roycroft> sure, because wood will swell up more than 0.0002" when the humidity changes :P
[22:41:49] <CaptHindsight> you mean you don't have a temp and humidity controlled shop?
[22:41:58] <roycroft> that does not matter
[22:42:08] <roycroft> most parts eventually escape the shop and head out into the wild
[22:42:49] <roycroft> for what i'm doing right now, stepper motors will be fine i think
[22:43:14] <CaptHindsight> yes, fine
[22:43:38] <CaptHindsight> if you can stand the noise :)
[22:43:50] <roycroft> 1. earplugs
[22:43:52] <roycroft> 2. go somewhere else
[22:43:58] <roycroft> two easy solutions :)
[22:44:16] <roycroft> something tells me the spindle motor will make more noise than the stepper motors

[22:53:32] <zeeshan|2> it took me 4 days to write the driver for the vfd
[22:53:37] <zeeshan|2> and integrate it into linuxcnc
[22:53:44] <zeeshan|2> i bet thats highly impossible with mach
[22:54:59] <CaptHindsight> some people like it since they just configure it with some graphical tools
[22:55:10] <zeeshan|2> hm by with stepconf
[22:55:16] <zeeshan|2> you're up and running pretty quick
