[00:00:17] <FinboySlick> alex4nder: Every time I watch that vid I am awed by how quiet your mill is.
[00:01:09] -!- jv4779 has quit [Quit: Bye]
[00:01:27] <alex4nder> haha

[00:01:37] <alex4nder> FinboySlick: I think that's directly related to spindle load
[00:03:02] <FinboySlick> I'm probably just inexperienced. Most of my cuts have sounded like a skill saw through steel roofing.
[00:03:30] <alex4nder> what kind of mill do you have?
[00:03:47] <FinboySlick> Chinese Syil X5 Speedmaster.
[00:03:53] <alex4nder> ah cool
[00:04:25] <alex4nder> that's a pretty slick looking machine
[00:04:53] <FinboySlick> http://www.youtube.com/watch?v=SQWaDXjdtCI This one shows part of why it's so noisy ;) That was a terrible setup.
[00:05:39] <FinboySlick> But as you can hear, even the spindle is noisy.
[00:05:43] <alex4nder> ah yah
[00:05:49] <FinboySlick> And the water pump to cool it is too.
[00:05:57] <alex4nder> what RPM is that running at?
[00:06:02] -!- rob_h has quit [Ping timeout: 244 seconds]
[00:06:25] <FinboySlick> That was around 8000 I think. My spindle isn't supposed to spin lower than that.
[00:06:31] <alex4nder> ah ok
[00:07:03] <FinboySlick> I sort of bought it with small detailed parts in mind so I went for a high speed spindle.

[00:09:59] <alex4nder> as it spirals?
[00:10:05] <ReadError> yea
[00:10:16] <alex4nder> yah, it pauses there for a sec at each rotation
[00:10:33] <alex4nder> I'm working on a path generator that doesn't pause, and ramps better into the cut
[00:10:55] -!- jv4779_ has quit [Client Quit]
[00:10:56] <ReadError> ahh ok
[00:11:19] <alex4nder> you can actually hear the load change
[00:12:15] <alex4nder> right as it pauses, it puts more load onto the spindle as it has more radial engagement angle at that point that at any other point in the rotation
[00:12:30] -!- jv4779 has quit [Ping timeout: 252 seconds]
[00:13:28] <alex4nder> my new algorithm does a constantly expanding spiral, rather than small concentric circles.
[00:13:58] <alex4nder> there's already some spiral generating code for axis, but what fun is that. ;)

[02:22:52] <FinboySlick> I was sort of wondering how well that would work? I assume Mach3 knows how to offload stepgen to a USB device or is it really crazy enough to still be all CPU driven?
[02:24:22] <Jymmm> no idea, just thought it was funny someone in china made a board for it
[02:24:43] <FinboySlick> It has what could be a large PIC on it.
[02:25:07] <A1Sheds> i was just wonder what USB slave device they are using

[02:57:42] <jdhNC> what's a pedobear?
[02:58:00] <FinboySlick> Internet meme... He's pretty much the mascot for anything pedo on the net.
[02:58:16] <alex4nder> we're having an internet culture clash.
[02:58:20] <Jymmm> FinboySlick: knows this from experience?

[02:58:53] <alex4nder> if you don't know what pedobear is, you've been asleep at the Internet for over a half decade.

[02:59:33] <Jymmm> with you calling it pedo, and seeing a hole in the crotch, I don't wanna know!
[02:59:42] <alex4nder> wut?
[03:00:07] <Jymmm> theres a hole in the crotch http://iw.suntekstore.com/office_cache/263/14003158/iw1320805565_image.jpg

[03:01:26] <FinboySlick> I mean, the one on the right.
[03:01:46] <FinboySlick> Could lead to confusion if you know his earlier time in germany.
[03:04:00] <alex4nder> hmm
[03:07:48] <alex4nder> anyone using a relay for spindle and/or coolant pump control?
[03:08:04] <jdhNC> I have an SSR on my spindle and vacuum
[03:08:37] <alex4nder> cool
[03:08:46] <alex4nder> DIN rail mounted?
[03:08:59] <jdhNC> duplex outlet box mounted.
[03:09:47] <alex4nder> cool
[03:09:49] <jdhNC> it's an Opto SSR, not very DIN friendly
[03:10:14] <jdhNC> it's mounted in the bottom of a deep outlet box. Just switches A/C to them.
[03:10:55] <Connor> I built one like that for my router too.. But, It's like a extension cord.. so, I could use it with other things too.
[03:11:51] -!- jv4779 has quit [Quit: Bye]
[03:11:55] <alex4nder> I'm thinking of just putting switched sockets on the outside of my junction box

[03:12:35] <alex4nder> 3 prongs
[03:12:50] <jdhNC> I'm going to do that for my mill, but the power will just be switched via the estop circuit
[03:13:21] <alex4nder> cool
[03:13:45] <alex4nder> I'm using the standard Taig light-switch box right now, I'd like to put it under linuxcnc control via the g540
[03:14:12] <jdhNC> are you using the g540 charge pump with linucnc?
[03:14:15] <alex4nder> yah
[03:15:36] <jdhNC> no problems?
[03:15:53] <alex4nder> not that I've seen so far, but I've only been running it since the new Atom, so a couple of days
[03:19:52] <alex4nder> jdhNC: I think I may ditch the DIN idea.. there's a ridiculous price increase for no added benefit to me.
[03:20:44] <jdhNC> make some cutouts, $0.59 outlet, $0.29 outlet plate
[03:21:55] <jdhNC> doesn't the g540 have a relay?
[03:22:05] <ReadError> what benefit does charge pumps bring?
[03:22:14] <ReadError> i got them off, havnt tried with them on
[03:22:22] <jdhNC> kills the system if the SW stops pumping.
[03:23:07] <Connor> ReadError: Safety.
[03:23:15] <alex4nder> jdhNC: no, no relay.. just some outputs..
[03:23:24] <alex4nder> specifically two of them

[03:26:07] <ReadError> Connor: how?
[03:26:32] <alex4nder> ReadError: have you noticed your steppers twitching when you boot your machine?
[03:26:42] <alex4nder> or reboot with everything powered up
[03:26:53] <ReadError> havnt done that yet
[03:27:17] <alex4nder> I started using chargepump because of that.
[03:27:36] <alex4nder> especially if I want the mill to stay at a certain position when I reboot the machine.
[03:27:39] -!- phantoxeD has quit [Ping timeout: 245 seconds]
[03:28:06] <Connor> You config EMC to send out a charge pump signal (Typical 12.5Khz signal). If the Charge Pump doesn't see the signal, it turns off the relay.. which, you should have wired into your Break Out Board, and power supply, disabling both..
[03:28:34] <djdelorie> do the charge pump signals stop when e-stop is asserted?
[03:28:49] <Connor> That way, if EMC locks up, the computer reboots or something.. You machine stops..
[03:28:53] <alex4nder> djdelorie: depends on how you configure it
[03:29:28] <Connor> Some people wire the E-Stop in so it's in series with the charge pump signal, so, hitting the E-Stop is the same as the charge pump tripping.
[03:29:51] <alex4nder> the G540 faults if it doesn't receive chargepump (with it enabled), and fault is the same input pin as e-stop
[03:30:10] <alex4nder> so I just send charge-pump all the time.
[03:30:23] <alex4nder> (for right now)
[03:32:39] <Connor> The reason for a 12.5Khz signal vs just a on/off is because the 12.5 requires software to generate it.. a on or off can be a fault..
[03:33:02] <ReadError> alex4nder: i unplug everything after my cuts
[03:33:10] <ReadError> then plug it in when im ready to cut again
[03:33:32] <alex4nder> cool
[03:35:10] <ReadError> ill probably put a switch on my controller box
[03:36:25] <alex4nder> give it a couple months.. ;)
[03:39:56] <alex4nder> with my taig I feel like I'm building a honda civic for drag racing
[03:40:21] <alex4nder> or maybe a Mitsubishi Evo is a more appropriate car
[03:41:49] <ReadError> seems decent to me
[03:42:07] <ReadError> well, for what im doing
[03:42:16] <alex4nder> http://www.jeffree.co.uk/images/taig-mill-p2-photo10.jpg <- I like that column mounted wiring setup
[03:42:22] <alex4nder> would be even better with waterproof connectors

[03:43:32] <ReadError> whats the different color mean?
[03:44:00] <ReadError> metric?
[03:44:12] <alex4nder> of the mill?
[03:44:16] <alex4nder> it's probably just old
[03:45:15] <alex4nder> there is/was also a UK reseller 'peatol'
[03:48:21] <Jymmm> alex4nder: isthat your mill?
[04:04:56] <alex4nder> Jymmm: which?

[12:01:53] <andypugh> I have done some metal-spinning on an ordinary lathe, it's a useful method to be aware of.
[12:04:42] <JT-Shop> I've never seen a tool like the two handed one
[12:05:39] <JT-Shop> I visited a shop that makes light fixtures and they had several stations spinning the reflecters for outdoor lights
[12:08:27] <JT-Shop> they were all CNC metal spinners
[12:12:02] <Jymmm> This seems like WAY TOO MUCH EFFORT for an "air tank" http://www.youtube.com/watch?v=44cuKCCzUwk&feature=player_embedded
[12:12:14] <Jymmm> of it's size
[12:13:37] <Jymmm> JT-Shop: Is this type fuse waterproof, or do they specifically state waterproof if it is? http://www.pyrodirect.com/ecom-prodshow/058-0105-C.html
[12:14:26] <archivist> good selection of calenders on the wall of that spinning shop :)
[12:14:44] <JT-Shop> some say waterproof some say water resistant some don't say
[12:14:56] <Jymmm> JT-Shop: Also, is there something special you have to do to cut fuse? Use high flint content wire cutters? Ceramic scissors?
[12:15:07] <Jymmm> JT-Shop: Those don't say =)
[12:15:23] <JT-Shop> just normal sissors is what we use
[12:15:52] <Jymmm> I like the long burn time. Oh, hmmm, they have a "special" till they're selling just didn't know
[12:16:01] <Jymmm> tool
[12:17:43] <Jymmm> JT-Shop: They sell REAL sparklers too!!!! wohoo
[12:18:40] <Jymmm> I haven't seen real sparklers in 10+ years
[12:21:20] <Jymmm> As it is now, only one city in this County sells 'Safe and Sane' fireworks and the Fire Marshall limits the type of fireworks they sell. Usually I have to "import" them from the next county over as the rest of the cities have a ban on all fireworks
[12:22:57] <Jymmm> All the big companies, City, and the colleges used to put on a nice aerial show, now no budget for it, can't buy/use fireworks, so now the neighborhood has better aerial fireworks than the city does!
[12:23:17] <JT-Shop> I like the tektronix board, you can't contact an admin unless your logged in... you can't log in till they approve you
[12:24:00] <Jymmm> The City would shut down the freeway, and put on a show, it was just one huge drunken party on the freeway =)

[12:57:58] <JT-Shop> yea I know but he didn't
[12:58:34] <Jymmm> oh, I stopped listening when he said firecracker using a bullet
[12:59:08] <Jymmm> Ok I lied, I stoped listen when he said wateproofing using hot melt glue
[13:00:02] <Jymmm> JT-Shop: how do you store fuse?
[13:04:50] <Jymmm> JT-Shop: do yo have one of those big yellow boxes?
[13:10:48] <Jymmm> I can't tell you how many times I've come across firecrackers with this fuse... http://www.youtube.com/watch?feature=player_embedded&v=VODSMhWnse8
[13:14:56] <JT-Shop> in a zippy bag or an old powder container for the cut ones
[13:19:42] <Jymmm> JT-Shop: so an empty metal container would work, like those empty paint cans and lid?
[13:20:18] <JT-Shop> anything seems to work, when you purchase it has no container
[13:20:56] <Jymmm> JT-Shop: Ah. I may be a pyro, but I'm a very respectful pyro =)
[13:21:59] <Jymmm> I guess an aluminum contiainer would be better =)

[15:17:32] <ReadError> figured it would be simple to monochrome it

[17:17:14] <IchGuckLive> B)
[17:17:44] <IchGuckLive> Aero-Tec: Mashine config ok
[17:17:45] <elmo401> IchGuckLive: any more deep sea oil leaks?
[17:18:17] <IchGuckLive> alot but not critical
[17:19:13] <IchGuckLive> elmo401: bewlow 10k barol a day noone asks
[17:19:56] <elmo401> indeed
[17:20:18] <elmo401> id like to find that 10k barrel per day 'leak' and take it for myself!
[17:20:39] <IchGuckLive> this woudt make you a ritch man
[17:21:15] <IchGuckLive> around 8k people came to visit the CNC show jesterday
[17:21:33] <IchGuckLive> oberall i think 20k on the campus
[17:26:00] <elmo401> nice turn out
[17:26:43] <elmo401> IchGuckLive: 10,000 barrels per day won't make me a 'rich' man, eh? interesting... at $100/barrel that is a fairly good DAILY income ;)
[17:26:45] <andypugh> I just found a reason not to like Inventor Fusion, and it's quite a major one. It isn't associative. So you can't change a sketch profile and have the extruded part update.
[17:27:02] <elmo401> IchGuckLive: now, where do I locate these leaking oil holes in the bottom of the ocean
[17:27:14] <IchGuckLive> elmo401: Tax and production reduces the win
[17:27:22] <elmo401> andypugh: really? that's lame. SolidWorks does
[17:27:30] <elmo401> IchGuckLive: ocean has no tax
[17:27:44] <archivist> solidworks++
[17:27:52] <andypugh> Inventor does. This is Inventor Fusion, which is aimed at a different market.
[17:28:32] <archivist> inventor when I tried it was behind solidworks
[17:28:35] <IchGuckLive> andypugh: move to a real 3D system that dont uses NURBS
[17:28:36] <elmo401> ill be like one of the founders of Facebook and claim Signapore as my residence and pay little taxes. that fucking cheating bastard. gonna make almost $4B on facebook going public and runs off to singapore to save on taxes.
[17:30:21] <IchGuckLive> monaco is best for taxes
[17:30:59] <elmo401> perfect. ill put the business in Monaco and have the business pay all my personal expenses, since ill only be a 'consultant' ;)
[17:31:00] <andypugh> IchGuckLive: Autodesk Inventor is a proper professional package, I used to be paid to drive it. Inventor Fusion is not, but does have the advantage of running native on my Mac, and is currently in free Beta.
[17:31:31] <elmo401> still, need to locate a few of these leaking wells
[17:31:35] <IchGuckLive> then you got to live with it

[17:33:06] <andypugh> To be fair to Inventor Fusion, it's very slick and I like the interface.
[17:33:29] <IchGuckLive> agree
[17:34:06] <IchGuckLive> why arend you using for masining pars like yours librecad and heekscnc

[17:35:27] <IchGuckLive> and all for nothing of cost at all with full service backround
[17:35:47] <andypugh> Well, the main reason is that I am fluent in Inventor, so can get what I want very quickly.
[17:35:55] <archivist> because no assemblies and bugs
[17:35:57] <IchGuckLive> updates weakly on all system plattforms
[17:36:06] <andypugh> (But I can't get what I want in Fusion)
[17:36:50] <IchGuckLive> i never within the last 15years i worked with autodesk
[17:37:08] <andypugh> One of the reasons I updated my Mac to a Core i5 was that FreeCAD didn't run on the 32-bit CPU in my old one.
[17:37:11] <IchGuckLive> i got my foreman licence on R10
[17:37:27] <andypugh> Inventor and AutoCAD are hugely different.
[17:37:52] <andypugh> About the only thing in common is that they are by AutoDesk

[17:38:50] <IchGuckLive> yes
[17:39:06] <IchGuckLive> its basicly Qcad eqaling R12
[17:39:13] <andypugh> I can only work in 3D :-)
[17:39:37] <IchGuckLive> heekscad gives you with 2 klicks the 3D part
[17:40:16] <IchGuckLive> have you seen my howto on this sketch->part->g-code
[17:40:23] <andypugh> I really didn't get on with the HeeksCAD workflow last time I tred
[17:40:37] <elmo401> GibbsCAM is not bad, for 2D.
[17:40:52] <elmo401> 3D is still a little 'odd' compared to what im used to drawing with (solidworks)
[17:40:55] <IchGuckLive> if you are on inventor-fusion stay with it
[17:41:04] <IchGuckLive> there are somany howtos on youtube
[17:41:12] <elmo401> andypugh: seems like Heeks is stuck at 0.18
[17:41:38] <andypugh> Except that Inventor Fusion can't do all that I am used to doing in Inventor. Like associative modelling, and 3/4 section view.
[17:41:45] <andypugh> Or threads, for that matter.
[17:42:23] <IchGuckLive> im on full 3D modeling so no way to get back to nurbs eytruding
[17:43:10] <IchGuckLive> workflow in ProE is the same as in the Factury get the raw part and ter it down to the part
[17:43:48] <IchGuckLive> everyones choise to do what he best can
[17:45:35] <andypugh> Yes, that's how Inventor works. And to an extent Fusion too, but you are expected to pull and push the model to change it, not type in dimensions.

[20:17:02] <joe9> i have not used them yet.
[20:17:20] <alex4nder> ok
[20:17:28] <alex4nder> well I'll order some up
[20:17:38] <alex4nder> I looked around locally, and found jack and shit
[20:18:28] <Loetmichel> hrhr, i like double sided (carpet) tape... six pieces of slate leveled... with the same tape on the machine... ;-)
[20:18:38] <Loetmichel> http://bambuser.com/v/2642805
[20:19:22] <alex4nder> no vacuum table? ;)
[20:19:51] <Loetmichel> just doublesieded tape on a plastic table ;-)
[20:20:23] <joe9> Loetmichel: that is cool.
[20:20:29] <joe9> will have to check that out myself.
[20:20:41] <joe9> cannot believe it held it so well.
[20:20:44] <Loetmichel> bad thing: in the slate are some quarz inclusions... that NOT what the TC bit likes...
[20:21:00] <alex4nder> hah
[20:22:32] <alex4nder> joe9: are you running Debian or something else?

[20:26:23] -!- Keknom has quit [Quit: Leaving.]
[20:26:46] <Loetmichel> joe9: be careful when testing: i have a special carpet tape that is intended for temporaty fixing dance PVC-"carpet" to stages.
[20:27:16] <Loetmichel> it has one 15N side and a 50N side and a middle layer of paper, not plastic foil
[20:27:35] <elmo401> there is precision double sided tape. we used it a few times on our machines at work.
[20:27:42] <alex4nder> Loetmichel: does that stuff release with a heat gun?
[20:27:47] <elmo401> they guarantee 0.002" tolerance in flatness
[20:28:00] <Loetmichel> alex4nder: wit soapü and water if neccessary
[20:28:03] <Loetmichel>
[20:28:13] <Loetmichel> but a heat gun will work also
[20:28:20] <Loetmichel> or 2-propanol
[20:28:26] <elmo401> yes, alcohol
[20:29:01] <mrsun> diff p ca 1mm ver 4 meter vid trbyggnation, r det bra nog? :)
[20:29:19] <alex4nder> Loetmichel: I mean for release from the table.

[20:29:50] <Loetmichel> spray on, warit 2 min, wipe it offf
[20:30:04] <elmo401> how we did it was we used a block to stick the part on and put the block in the vice, then when done soaked the entire setup in a bucket of alcohol for a few hours.
[20:30:16] <mrsun> doh :P
[20:30:18] <mrsun> wrong channel :P
[20:30:18] <andypugh> There is stuff designed to replace spot-welding too, you probably don't want that one. 3M VHB tape.
[20:30:35] <elmo401> our part was 6" x 9" surface area. took longer then 2 min ;)
[20:30:36] <Loetmichel> 'cause the glue carrier is made of paper the alcohol can go through it and dissolve the glue underneath
[20:30:51] <elmo401> andypugh: ya, VHB rocks!
[20:30:59] <elmo401> GM uses it on their vehicle trim
[20:31:00] <alex4nder> ah
[20:31:19] <Loetmichel> andypugh; i have a tape similar to VHB in the company...
[20:31:28] <fragalot> I tried to use VHB tape for pcb milling
[20:31:35] <ReadError> so i noticed a huge difference in direction of cutting
[20:31:50] <ReadError> when i cut CCW, the finish on the inner part was much smoother
[20:31:51] <fragalot> worked great, apart from the fact that I ruined the boards trying to get them off again
[20:31:54] <fragalot> lol
[20:32:01] <ReadError> vs, CW, it was smoother on the outside
[20:32:06] <Loetmichel> one can tape a M6 nut to the wall and screw a stub in and hang your jacket on it :-)
[20:32:13] <elmo401> I saw a demo at a trade show. the guy took two pieces of 24" 3/4" I-beam, put only 2 strips, one at each end. sat the piece on top and waited 5min. then took the winch and raised both of them and started to add weights. it never released!
[20:32:53] <elmo401> ReadError: yes, Climb milling should net you a smoother finish
[20:33:09] <Loetmichel> fragalot: thats why i use the dancing carpet tape
[20:33:19] <elmo401> but if you do not have ballscrews you will get bad results ;)
[20:33:26] <Loetmichel> it has a defined difference in glue.
[20:33:40] <Loetmichel> one side has 15N to peel it off, the other 50 N
[20:33:50] <andypugh> Loetmichel: How do you telll which side is which?
[20:34:03] <Loetmichel> so you can tape it to the machine and gurantee that te workpiece has no tape on it
[20:34:46] <Loetmichel> andypugh: the side you have oben wenn fresh from the roll is tha 50N side, the one you have to peel the wax paper off is the 15N side.. Easy
[20:35:08] <Loetmichel> s/oben/open
[20:36:20] <elmo401> Loetmichel: what is the brand? have a website? I'd like to see this stuff
[20:36:47] <Loetmichel> sorry
[20:36:59] <Loetmichel> i kenw it from my ex-job (stage hand)
[20:37:10] <Loetmichel> so i asked my ex-boss to order me some
[20:37:49] <Loetmichel> was a german company, and i had to order a box full-> 50 rolls a 50m*50mm
[20:37:59] <fragalot> Loetmichel: yeah :P but the VHB was all I had lying around at the time
[20:38:00] <fragalot> xD
[20:38:07] <Loetmichel> so i have enough for lifetime, but dont know the manufactuurer ;-)
[20:38:48] <Loetmichel> wasnt dirt cheap either.
[20:38:57] <Loetmichel> the 50 rols were about 250$
[20:39:07] <fragalot> Loetmichel: VHB is like that price for a single one
[20:39:08] <fragalot> >.<
[20:39:36] <fragalot> Anyway 's getting late

[20:42:06] <fragalot> tin foil hats!
[20:42:30] <Loetmichel> wrong
[20:42:40] <Loetmichel> a tin foil hat would reflect the signal
[20:42:48] <fragalot> that counts as shielding
[20:42:49] <fragalot> somewhat
[20:42:57] <Loetmichel> the "felt" converts it to heat
[20:43:31] <Loetmichel> it Dampens any signal above 100Mhz and below 4GHZ about 20dB

[22:10:10] <andypugh> It's only a few circles and a curve.
[22:11:01] <andypugh> However, if you monochrome that you might find that image2gcode can raster-mill it for you. Bit that's a silly way to do it.

[22:11:31] <ReadError> i need to do the holes

[22:47:28] <andypugh> But why would you have that problem, and not anyone else?
[22:47:45] <andypugh> I would be tempted to hide my Xorg.conf file if I was you :-)
[22:48:38] <gene__> The code sample at that link (good Q andy) shows the right way to "void creatWindow()"
[22:48:48] <gene__> And let it regenerate it?
[22:49:27] <gene__> Or is this X that smart?
