[00:18:55] <Connor> trying to find some good pictures of people limit switches installed...
[00:20:16] <r00t4rd3d> what controller do you have
[00:21:09] <Connor> huh?
[00:21:27] <r00t4rd3d> like a gecko or tb6560
[00:21:38] <Connor> Keling 5056
[00:22:25] <roycroft> have you tried going to images.google.com and typing "limit switch installation"?
[00:22:38] <r00t4rd3d> or youtube
[00:22:39] <Connor> looking on the cnczone right now..
[00:22:51] <r00t4rd3d> ive learned alot from youtube
[00:22:53] * roycroft notes the non-answer
[00:23:11] <Connor> but, yes, I've done goggle search too
[00:23:31] <roycroft> i just went to the google images site, typed that in, and got heaps of useful results
[00:24:19] <roycroft> but i don't know exactly what you're trying to learn from the images you're seeking, so perhaps that is not the most useful query for you
[00:24:35] <r00t4rd3d> finding someone alive on irc who has done it though is that much better
[00:24:55] <roycroft> generally, yes
[00:25:00] <Connor> I have a slew of micro switches, all wither levers.. non with rollers..
[00:25:36] <Connor> trying to see if anyone has used non roller kind.. planning on one switch for X and one for Y (center mounted)
[00:26:23] <Jymmm> Connor: WTH?! It's LIMIT switch, not CENTER switch.
[00:27:22] <Connor> Jymmm: You put switch in middle.. You put stops on either end.. and your done. ??
[00:27:39] <Jymmm> again, it's LIMIT
[00:28:02] <Jymmm> you have reached the limit, the end, there is no more.
[00:28:25] <roycroft> right - you put two switches on each axis
[00:28:46] <Jymmm> If you want a HOME switch in the middel, so be it.
[00:28:48] <Jymmm> middle
[00:29:13] <roycroft> you use all nc switches, and connect them in series
[00:29:31] <roycroft> if ever that circuit opens, you stop
[00:29:36] <Connor> Yes, I know all that.. WTF does it matter were the switch is at as long as it trips at the end of the travel ?
[00:30:06] <Jymmm> key word, END, not MIDDLE.
[00:30:10] <roycroft> a dp switch could work
[00:30:10] <Connor> We're talking a Mill, not a router..
[00:30:23] <roycroft> center closed
[00:30:26] <roycroft> left or right open
[00:30:30] <Connor> http://www.micro-machine-shop.com/RF_power_feed_limit_switch.jpg
[00:30:35] <Connor> example image.
[00:30:36] <roycroft> you could do that with one switch on each axisw
[00:31:19] <roycroft> ok, that's a kind of nc dp switch
[00:31:40] <Connor> Is a micro or optical sensor in there.. and gets tripped in either direction.
[00:31:59] <Connor> http://media.digikey.com/photos/CK%20Comp%20Photos/11TL604,%2011TL602.jpg
[00:32:03] <roycroft> so that's what you have?
[00:32:21] <Connor> No. I just have a micro.. but I can make a enclosure.
[00:32:46] <roycroft> two switches in the enclosure, one facing right and one facing left?
[00:34:23] <Connor> No, just one. I guess I need to get some ones with rollers.. or bend the lever rounded..
[01:29:21] <alex4nder> hey
[02:49:27] <DJ9DJ> moin
[05:04:48] <Tectu> here you go guys: http://www.youtube.com/watch?v=k7T9jM97geY
[05:09:26] <Loetmichel> mornin'
[05:09:32] <alex4nder> sup Loetmichel
[05:11:48] <alex4nder> Tectu: nice
[05:12:56] <Loetmichel> Tectu: hmmm
[05:13:13] <Loetmichel> a bit much material for a reprap?
[05:13:37] <Loetmichel> but: nice construction!
[05:20:59] <alex4nder> so .. I made my own oil-based coolant
[05:21:05] <alex4nder> I'm wondering how well this is going to work.
[05:25:20] <Thetawaves> canola oil has been working well for me
[05:25:51] <alex4nder> you flooding your mill with it?
[05:26:02] <Thetawaves> i'll try peanut oil next, but it is more expensive
[05:26:05] <Thetawaves> yeah, flood
[05:26:10] <alex4nder> nice
[05:26:16] <alex4nder> any bacteria problems?
[05:26:33] <Thetawaves> none, there is no water in the mix.
[05:27:14] <Thetawaves> it made my cuts burr free
[05:27:20] <Thetawaves> it was amazing.
[05:27:57] <Thetawaves> i think the burs are mostly chips cold welding to the material behind the cutter, the oil flushes it away
[05:28:32] <alex4nder> what kind of pump are you using?
[05:28:47] <Thetawaves> a simple 300gph pond pump
[05:28:52] <alex4nder> nice
[05:28:53] <Thetawaves> because i already had it
[05:29:12] <Thetawaves> it pumps oil pretty well if you have a pig enough hose on the output
[05:29:17] <Thetawaves> big*
[05:29:40] <Thetawaves> for the same price you can get a positive displacement pump that will really pump oil at walmart
[05:30:19] <Thetawaves> if money is involved, definitely get the positive displacement pump
[05:30:59] <alex4nder> yah, the pond pumps I saw had a lot of bypass under any real restriction
[05:32:19] <Thetawaves> i use cooking oil because my machine is in my dining room... just feels a whole lot safer
[05:32:38] <Thetawaves> not because i need cheap oil or think it's superior cutting fluid
[05:33:29] <alex4nder> right. which machine?
[05:33:56] <Thetawaves> 3020T engraving machine
[05:34:27] <alex4nder> ah cpp;
[05:34:30] <alex4nder> er cool
[05:34:44] <alex4nder> nice and small
[05:35:02] <alex4nder> what're you doing with it?
[05:35:32] <Thetawaves> engraving... i made some designs in plate aluminum
[05:35:45] <Thetawaves> and circuit boards, lots of circuit boards
[05:35:55] <alex4nder> nice
[05:36:47] <Thetawaves> i am in the process of upgrading from 200w to 300w spindle motor
[05:36:56] <Thetawaves> :D
[05:38:12] <Thetawaves> i can fit 1/4" endmills in that thing
[05:40:06] <Thetawaves> so sorry alex4nder, what did you make your fluid out of?
[05:42:06] <alex4nder> the mix I'm going to test tomorrow is: water, mineral oil, tide ultra laundry detergent, and redline water wetter
[05:42:34] <Thetawaves> scary
[05:42:43] <Thetawaves> i was researching home made cutting fluid on google
[05:43:04] <jthornton> what are you cutting?
[05:43:13] <Thetawaves> and one of the main results was a cdc report about how this machinist got flesh eating bacteria in his hand while changing the cutting fluid
[05:43:16] <alex4nder> aluminum and steel
[05:43:42] <jthornton> for aluminum you just need some water with dish soap in it
[05:44:11] <Thetawaves> what about your machine tools?
[05:44:12] <alex4nder> jthornton: that's basically what this is
[05:44:48] <alex4nder> the mineral oil and water wetter are there to counter act rust and corrosion
[05:44:49] <jthornton> what is the mineral oil for?
[05:44:55] <jthornton> ah ok
[05:46:08] <jthornton> I use sodium nitrite in my plasma water to stop any corrosion
[05:46:28] <alex4nder> Thetawaves: you can get flesh eat bacteria from a spider bite.
[05:46:44] <Thetawaves> flesh eating bacteria is very rare.
[05:49:47] <Thetawaves> ok my mistake
[05:49:48] <Thetawaves> "Flesh-eating bacteria" is a misnomer, as the bacteria do not actually "eat" the tissue. They cause the destruction of skin and muscle by releasing toxins (virulence factors), which include streptococcal pyogenic exotoxins. S. pyogenes produces an exotoxin known as a superantigen. This toxin is capable of activating T-cells non-specifically, which causes the overproduction of cytokines and severe systemic illness (Toxic shock syndrome).
[05:50:09] <Thetawaves> and there are a few families of bacteria capable of this
[05:50:34] <Thetawaves> apparently the infection is the really rare part
[05:51:27] <jthornton> we have billions of brown recluse spiders that have a hemotoxin venom
[05:52:43] <Thetawaves> HAHA
[05:52:44] <Thetawaves> Jeff Hanneman, guitarist for the thrash-metal band Slayer, contracted the disease in early 2011. He was allegedly infected after being bitten by a spider.[22]
[05:52:57] * Thetawaves firmly places foot in mouth
[05:54:13] <TekniQue> 10:33:03 < Thetawaves> and one of the main results was a cdc report about how this machinist got flesh eating bacteria in his hand while changing the cutting fluid
[05:54:16] <TekniQue> yikes
[05:57:14] <Thetawaves> yeah
[05:57:21] <Thetawaves> like i said, scary
[05:57:29] <Thetawaves> gnight fellas
[05:58:03] <jthornton> night
[05:58:19] <jthornton> does xchat have a time stamp feature?
[05:58:39] <TekniQue> yes
[05:59:03] * jthornton tries again to find out how to turn it on
[06:00:44] <jthornton> the only thing I can find is for the logs, when I used to use chatzilla it had the time in the messages
[06:10:20] <archivist> interface->text box->time stamps
[06:10:27] <jthornton> dang I finally found it
[06:10:39] <jthornton> thanks archivist
[06:40:38] <jthornton> archivist, got a minute to review something for me?
[06:40:57] <archivist> sure
[06:41:02] <jthornton> http://gnipsel.com/shop/emc2/gcode.xhtml
[06:41:13] <jthornton> just a couple of pages I started the other day
[06:42:53] <archivist> in http://gnipsel.com/shop/emc2/tutorial/tut01.html "preamble that might be different" "preamble that might be in a different"
[06:43:49] <archivist> next section user decides dia/radius
[06:45:02] <archivist> devations-deviations
[06:45:54] <jthornton> opps forgot to run spell checker
[06:49:17] <archivist> arc diagrams dont match
[06:50:38] <jthornton> I see that now lol
[06:55:32] <archivist> you got the doc building going then!
[06:55:59] <jthornton> yea, a guy from the asciidoc google groups sorted me out
[07:25:44] <archivist> needs some navigation too
[07:26:09] <jthornton> yea, I've not got that far yet
[07:26:32] <IchGuckLive> hi all i finished my casel today with stone optics from foamcut http://mechmo.de/styrocat.html
[07:26:33] <jthornton> best would be to copy the linuxcnc index somehow
[07:32:16] <jthornton> IchGuckLive, pretty damm slick!
[08:04:40] <jthornton> well crap Xchat for winblows is $20 if you use more than 30 days
[08:11:08] <bedah> silverex is free windows xchat
[08:14:51] <archivist> jthornton, there is a fork of xchat called....ychat be very careful which ychat you get
[08:17:04] <archivist> is silverex renamed ychat :)
[08:23:28] <Geissler> jthornton, use crack for xchat? Or use ychat - it's free
[08:42:11] <jdhNC> Center format arcs are more accurate than radius format arcs
[08:42:15] <jdhNC> Why is that?
[08:46:06] <ctjctj> jdhNC: Because you state explicitly the points where you want the arc to end.
[08:46:22] <ctjctj> jdhNC: whereas the other is a calculated end point.
[08:47:20] <jdhNC> ok, so the end point is more accurate, doesn't that make the radius less accurate?
[08:47:44] <ctjctj> Not really.
[08:48:13] <jdhNC> why not, the center of the arc radius is calculated.
[08:48:50] <ctjctj> Do you care if the center of the arc is off by 1/1000 in a 2 inch circle?
[08:49:02] <ctjctj> Not really, you care where the cutter runs.
[08:49:49] <jdhNC> guess I'd have to see the actual error to know if I cared.
[08:50:45] <ctjctj> They are different types of calculations is the best answer I can give. I'd have to go dig into the math a little more in order to answer better. But the gist is that using angles isn't as accurate.
[08:51:39] <ctjctj> If your angle is off by 1/1000 and your radius is 10 inches then your final point is going to be off by 1/1000 * 10 or 1/100.
[08:51:54] <jdhNC> why would your angle be off at all?
[08:52:14] <ctjctj> because you are using floating point numbers going in to sin/cos functions.
[08:53:17] <jdhNC> bah, computers are perfect!
[08:53:28] <freespace> best lie we have ever told
[08:53:29] <jdhNC> for some approximation of perfect.
[08:55:44] <ctjctj> The issue is the multiplication affect. Every point you define is off by a value less than epsilon. You can make epsilon as small as you want but the smaller it gets the harder it is to do. But anytime you can multiply epsilon your error gets that much bigger. :-(
[08:56:11] <jdhNC> I understand the math, not not sure how much it matters.

[09:50:48] <logger[psha]> skunkKandT: Log stored at http://psha.org.ru/irc/%23linuxcnc/2012-05-05.html
[11:19:51] <Jymmm> jdhNC: Say yo had a level, and it was off by 100th of a degree. Now, you're building a cider block wall and you use that level to make sure the wall is perfectly straight. When you build up the wall to 30 some-odd feet, it's gonna be tilted out.
[11:21:42] <Jymmm> ...as the errors are cumulative.
[11:21:46] <archivist> there is a chance you reverse the level so it should average out straight
[11:22:27] <archivist> but no one uses a level without checking it do they
[11:22:50] <Jymmm> True, especially if you happen to know that is exactly how you check the accuracy of a level, most don't =)
[11:33:28] <Jymmm> 220VAC RED LED Panel lights (22mm) http://www.dealextreme.com/p/22mm-led-power-indicator-signal-lights-red-ac-220v-130360
[11:43:31] <Jymmm> IDEC Control illuminated Button http://www.dealextreme.com/p/red-indicator-light-engine-push-start-button-set-for-auto-refitting-dc-12v-24560 and it looks liek the contact are also rated for 120V http://www.alliedelec.com/search/productdetail.aspx?sku=70172633#tab=specs
[11:45:36] <Jymmm> And in Blue http://www.dealextreme.com/p/blue-indicator-light-engine-push-start-button-set-for-auto-refitting-dc-12v-24561
[11:50:25] <alex4nder> hey
[11:53:54] <Jymmm> ve7it: LOL, The worlds skinnyest dummy load... http://www.dealextreme.com/p/100w-high-gain-antenna-vhf-uhf-117735
[11:55:15] <Jymmm> ve7it: I just don't see where you add the mineral oil =)
[11:57:19] <TekniQue> lol 100 watts on that thing would probably result in some amounts of smoke
[11:57:35] <Jymmm> TekniQue: Yeah, in the radio =)
[11:58:06] <TekniQue> yes, 95% standing wave ratio
[11:58:12] <TekniQue> boom
[11:58:45] <Jymmm> I dont know about 'boom', but I suspect a lot of snap crackle and pop
[11:59:31] <Jymmm> TekniQue: and who in the hell uses a 14" antenna with a PL259 connector?!
[11:59:40] <Jymmm> on 2m/440
[12:01:13] <Jymmm> TekniQue: you a ham?
[12:01:22] <TekniQue> nope
[12:01:29] <Jymmm> ah, ok
[12:01:37] <TekniQue> but I have a VHF radio
[12:01:52] <TekniQue> Yaesu 65 watt programmable
[12:01:52] <Jymmm> FRS ?
[12:01:57] <Jymmm> ah, cool
[12:02:13] <Jymmm> yaesu what?
[12:03:11] <TekniQue> I don't remember
[12:03:14] <TekniQue> it's a car radio
[12:03:24] <Jymmm> I figured that =)
[12:03:32] <Jymmm> (@ 65W)
[12:03:43] <TekniQue> I have a handheld also
[12:04:54] <Jymmm> Yeah, I want to mod my HT, just haven't gotten around to doing it yet
[12:05:34] <Jymmm> as then I need to reprogram it all over again.
[12:08:46] <TekniQue> I modded both of mine to transmit on any frequency
[12:08:59] <TekniQue> I have a few licensed channels
[12:09:27] <Jymmm> I've opened my mobile rig, just haven't done the HT yet.
[12:09:28] <TekniQue> but as they come from the factory they can only transmit on a narrow range of frequencies
[12:09:54] <Jymmm> what do you use them for?
[12:10:15] <TekniQue> chatting with my mates when travelling
[12:10:36] <Jymmm> ah
[12:10:57] <TekniQue> in offroad trucks
[12:11:23] <Jymmm> gotcha
[12:32:48] <Jymmm> jthornton: no pun intended http://mykitchenapron.blogspot.com/2011/08/white-trash-dip.html
[14:13:58] <SolarNRG> Hi guys
[14:14:06] <SolarNRG> Does anybody in here have a working induction melter?
[14:33:11] <Jymmm> hahaha
[14:34:43] <SolarNRG> Why is that funny?
[14:35:57] <Jymmm> Cause you were working on microwaves till I showed you that video =)
[14:37:46] <SolarNRG> I've now done 9 microwave experiments
[14:37:50] <SolarNRG> And I've lit a cigarette
[14:37:57] <SolarNRG> I faied to melt zinc, let alone ally
[14:38:04] <SolarNRG> even after hours of cooking
[14:38:24] <Jymmm> try solder as it has the lowest melting point I know of
[14:38:24] <SolarNRG> I'm giving up on the microwave idea, I'm sure there is a way to do it, now I'm going into induction
[14:38:31] <archivist> does the microwave still heat water
[14:38:34] <SolarNRG> I can do solder with a soldering iron
[14:38:35] <SolarNRG> Yes
[14:38:37] <SolarNRG> It does
[14:39:09] <Jymmm> if you cant melt solder with a microwave, your not going to melt any other metals that I'm aware of
[14:39:43] <alex_joni> Jymmm: there are lower melting temperatures than solder
[14:39:49] <SolarNRG> OK FORGET microwave.... I have really tried
[14:39:55] <Jymmm> as far as induction goes, your cheapest bet is a replacment element from an induction cooktop
[14:40:05] <archivist> try woods metal
[14:40:06] <alex_joni> I had some alloys which melted around 50-60C
[14:40:11] <Jymmm> for testing that is
[14:40:19] <archivist> http://en.wikipedia.org/wiki/Wood%27s_metal
[14:40:23] <SolarNRG> This was my last test http://www.youtube.com/watch?v=KuWEUnxG1SE
[14:40:24] <Jymmm> alex_joni: in a microwave?
[14:40:30] <SolarNRG> Fields metal
[14:40:35] <archivist> see table at bottom
[14:40:39] <alex_joni> Jymmm: no, in water
[14:40:59] <alex_joni> archivist: that's it :)
[14:41:12] <alex_joni> or something like that
[14:41:15] <archivist> they did a candid camera in a cafe with spoons made of it
[14:41:19] <ReadError> jeeeezee
[14:41:21] <SolarNRG> I have failed to do it by way of a microwave
[14:41:25] <alex_joni> right, I tried that too :))
[14:41:26] <ReadError> i didnt think creating a toolpath would be so difficult
[14:41:47] <SolarNRG> I now wish to listen to your advice and do it with an induction loop. I wanted to know if anyone here lives in the UK and has built one and I could paypal him to make me one for me
[14:41:49] <alex_joni> Jymmm: I used to that extract many pin DIPs
[14:41:57] <SolarNRG> Big enough for a medium crucible to fit in
[14:42:04] <Jymmm> alex_joni: ah
[14:42:07] <alex_joni> you can mix it with the existing solder, and just lift the DIP out
[14:42:16] <SolarNRG> I'd like to be able to melt a couple of litres of steel at once
[14:42:21] <archivist> SolarNRG, hehe...can you get enough current from the mains
[14:42:23] <alex_joni> the pins stay warm for a while, so it stays liquid
[14:43:38] <archivist> Im in the uk I want your money BUT think of the costs and practicalities
[14:47:32] <SolarNRG> Well i MUST do this outside
[14:47:35] <SolarNRG> safety first
[14:47:42] <SolarNRG> My extension lead can only handle 2.4kw
[14:47:51] <SolarNRG> I am using a domestic socket
[14:48:07] <SolarNRG> I think the most amount of amps I could extract would be 13amps@240v
[14:48:23] <archivist> not going to cut it
[14:48:32] <Jymmm> maybe melt a coat hanger
[14:48:42] <SolarNRG> With a rectifier and inverter that goes to 20khz
[14:48:48] <archivist> please adjust your dreams to include reality
[14:48:56] <Jymmm> archivist: Awwwwwwwwwwww
[14:49:10] <SolarNRG> Have a look at this kids: http://www.youtube.com/watch?v=2kuJ-FZBnok&feature=related
[14:49:20] <SolarNRG> His is only 150w
[14:49:27] <SolarNRG> He can heat up a nail
[14:49:43] <alex_joni> http://home.c2i.net/metaphor/mvpage.html
[14:49:46] <Jymmm> archivist: "No thanks, I'll just create my own reality instead! =)"
[14:50:23] <SolarNRG> alex, I did all that with the molochite, magnetite, graphite, I actually did it and I have a video of it
[14:50:56] <SolarNRG> http://www.youtube.com/watch?v=uh1VDGP86SY
[14:51:47] <SolarNRG> ^^ This was my magnetite test
[14:52:07] <SolarNRG> It got hot enough to singe rizla paper but not hot enough to melt metal
[14:54:04] <SolarNRG> I'm either doing something wrong or this guide is simply false information
[14:54:17] <SolarNRG> I'm losing faith in melting metals in a microwave oven
[14:54:28] <SolarNRG> I'm now thinking of the induction loop method
[14:57:03] <archivist> note this is 15kw
[14:57:07] <archivist> http://www.youtube.com/watch?v=k4xsqw463Hs&feature=endscreen&NR=1
[14:59:13] <SolarNRG> How is he not getting electrocuted?
[14:59:22] <Jymmm> whoa... cold enough to touch instantly, nice.
[14:59:28] <SolarNRG> Is it because the frequency is so high?
[15:00:48] <Jymmm> SolarNRG: Maybe you should read a bit about what your attempting to accomplish http://en.wikipedia.org/wiki/Induction_heating
[15:01:31] <mk0> Jymmm, finally! someone told it
[15:01:59] <Jymmm> mk0: I call em as I see em is all.
[15:03:31] <mk0> even our institute has 100 y.o. induction melting furnaces
[15:04:10] <Jymmm> mk0: That's kinda cool that 100yo gear is STILL working =)
[15:04:22] <SolarNRG> Can I switch off my fusebox, and hook up said system to my cooker wires at the back of my oven?
[15:04:42] <mk0> well i'm just joking that our equipment is so out of date, that i grind my teeth
[15:05:23] <Jymmm> mk0: Oh, heh. I thought a 100yo furnance was built so well that it survived all this time.
[15:05:38] <SolarNRG> Surely my cooker electric will allow higher current
[15:05:42] <SolarNRG> than a socket
[15:05:43] <mk0> and f...ing YES, it's from 60-s and stiill working
[15:05:56] <archivist> I drive a steam engine made in 1849
[15:06:07] <mk0> :D
[15:06:26] <Jymmm> mk0: Hell there are hippis/CEO's from the 60's still around for that matter =)
[15:06:37] <mk0> YES!!!!!
[15:06:51] <Jymmm> archivist: have you had to make replacement parts for it?
[15:07:06] <mk0> hly cow and this is not a joke. all our labs chiefs are from 40-s
[15:07:14] <archivist> Jymmm, yes
[15:07:34] <archivist> made a wooden bearing one day
[15:07:45] <mk0> they all hardly walk
[15:08:01] <alex4nder> hey
[15:08:14] <Jymmm> archivist: well, it is a moving part, so not really a fair comparison to a 100yo induction furnace
[15:08:47] <mk0> wooden bearing. you troll
[15:08:53] <Jymmm> lol
[15:08:54] <archivist> steaming tomorrow and monday
[15:09:04] <archivist> mk0, really not a joke
[15:09:49] <archivist> its the bearing for the outlet valve of the air pump
[15:10:26] <mk0> those, who operate equipment from 60-s do not ever joke
[15:10:47] <alex_joni> mk0: you were the one looking for foam?
[15:10:51] <mk0> i mean myself
[15:10:55] <alex_joni> it's in master
[15:11:04] <alex_joni> sim/axis/axis_foam.ini for an example
[15:11:08] <mk0> lookinf for foam in what sense?
[15:11:27] <mk0> nope, it was about xuyv-foam patch
[15:11:33] <alex_joni> yes
[15:11:41] <alex_joni> it's merged into master as of march
[15:11:42] <mrsun_> anyone got any good machining videos from youtube? .. maybe channels? :)
[15:11:48] <mrsun_> i need something to watch =)
[15:12:06] <mrsun_> hand machinists are the most fun to watch :P
[15:12:10] <syyl_ws> you know mr. mueller nicks videos?
[15:12:12] <mk0> hmm, i didn't see. i looked through several times but didn't see (
[15:12:17] <syyl_ws> about scraping, casting and a bit cnc
[15:12:19] <archivist> mrsun_, upset yourself with the fast tool changer on the brother cnc
[15:12:29] <mrsun_> archivist, already done ... :P
[15:12:41] <mrsun_> syyl_, seen :/
[15:12:52] <syyl_ws> :D
[15:13:17] <mrsun_> and KEFs ... and all of hoss, and all mrpete
[15:13:26] <syyl_ws> mh
[15:13:33] <syyl_ws> you could go to the shop
[15:13:41] <syyl_ws> machine something, make a video and watch that :D
[15:13:44] <mrsun_> syyl_ws, showered, naked and in bed :P
[15:13:57] <mrsun_> sleepy time here :/
[15:13:59] <syyl_ws> to much detail ;)
[15:14:13] <mrsun_> syyl_ws, pfft ... to much detail would be ... ;P
[15:14:31] <mk0> alex_joni, axis/axis_foam.ini for an example ! i read your post not carefully. Thanks!
[15:14:38] <mrsun_> syyl_ws, thats almost like a dare to say ... you know :P
[15:14:48] <syyl_ws> *runs away*
[15:14:54] <alex_joni> mk0: sim/axis/axis_foam.ini for an example ;)
[15:15:02] <alex_joni> that's the config you might want to try
[15:15:27] <mk0> yep i will definitely
[15:15:41] <mk0> xchat shows smileys??? oh, no...
[15:15:51] <syyl_ws> only yours Oo
[15:15:51] <archivist> mrsun_, search double ended lathe
[15:32:03] <SolarNRG> Well thanks for your help and advice, I think it is not a good idea to have an induction melter as I won't be able to power it effectively
[15:32:27] <mk0> yes
[15:33:33] <mk0> and maybe solar cells too...[joking
[15:33:41] <alex_joni> In practice, foundries use between 500 and 800 KWh /mt to raise steel to a little above its melting point of 1535deg C.
[15:34:29] <Jymmm> alex_joni: Shit, my lil hand held honda generate can do 800KW, no problem!
[15:34:42] <Jymmm> and only on one gallon of gas!
[15:34:59] <SolarNRG> That's probably more power than comes into my entire home
[15:35:38] <Tom_itx> 800Kw?
[15:36:16] <mk0> do not joke with big energies, without knowing you may find yourself dead. that's really not a joke.
[15:36:32] <Jymmm> Tom_itx: do you know of any speech modules that wotk with an ardunio?
[15:36:47] <Tom_itx> txt to speech or speech
[15:36:55] <Tom_itx> i have a couple speech boards
[15:37:18] <Jymmm> Tom_itx: Something simple to replace idiot lights for the blind
[15:37:22] <Tom_itx> one is just a recorder
[15:37:47] <Tom_itx> use a buzzer and beep out morse code
[15:37:53] <Jymmm> a counter is what I'm after
[15:38:14] <Jymmm> Tom_itx: Fine, you learn braille, and I'll use CW
[15:38:52] <mrsun_> Jymmm, impossible to generate 800KW on 1 gallon of gas
[15:39:19] <Jymmm> mrsun_: Sure it is, and in a HAND HELD generator too!
[15:39:20] <mrsun_> 34 - 40KW or something
[15:39:33] <mrsun_> and thats raw heat energy
[15:39:41] <mrsun_> without counting the mechanical losses in your engine :P
[15:40:14] <Jymmm> mrsun_: Dude, it was a joke, and I said in a HAND HELD (less than 40lbs) generator
[15:40:31] <Jymmm> mrsun_: Dont be goin all MrScience on us now =)
[15:40:36] <mrsun_> Jymmm, haha =)
[15:40:55] <mk0> :DD
[15:41:10] <mrsun_> cant remember the exact kw content of gas :/
[15:41:16] <SolarNRG> 1 gallon, hmm maybe 800kw for 30 seconds!?
[15:41:32] <Jymmm> 30mS maybe
[15:41:33] <mrsun_> SolarNRG, you got about 9kw or so per liter of gasoline
[15:41:38] <mrsun_> in energy
[15:41:38] <SolarNRG> IF you had an engine efficient enough
[15:41:39] <alex_joni> Jymmm: yeah, but you don't have one mt of metal
[15:41:48] <Jymmm> mt ?
[15:41:49] <alex_joni> I assume mt is metric ton
[15:41:55] <alex_joni> which is about 2000lbs
[15:42:06] <SolarNRG> So you'll get that amount of power for less than 100miliseconds then
[15:42:08] <Jymmm> alex_joni: what do I need with all that?
[15:42:09] <SolarNRG> per litre
[15:42:11] <SolarNRG> or about half a second
[15:42:14] <SolarNRG> for a gallon
[15:42:29] <SolarNRG> This kid made a 150w induction loop
[15:42:35] <alex_joni> but 800kWh for 2000lbs means you might need only lots less for 1-2lbs
[15:42:36] <SolarNRG> Why Can't I make a 2KW loop
[15:42:41] <SolarNRG> I think that is reasonable
[15:42:45] <alex_joni> I'm sure it's not linear though
[15:42:47] <SolarNRG> But I don't understand how to make it
[15:43:19] <SolarNRG> Maybe a 2kw loop wouldn't be super duper fast at melting metals but would it not suffice?
[15:43:26] <Jymmm> SolarNRG: Dude, just do propane and a leaf blower like everyone else.
[15:43:38] <mrsun_> SolarNRG, but still ... you have still only burned 1 gallon of gas ... and that still has no more then the 34 - 40kw energy content :P
[15:43:38] <SolarNRG> I'm against using combustible gases
[15:43:38] <mk0> ))))
[15:43:58] <SolarNRG> kw is powe
[15:43:59] <Jymmm> SolarNRG: What do you think will be produced from the molten metal?
[15:44:02] <SolarNRG> kw/h is energy
[15:44:16] <mrsun_> ahh true .. im just trying to sound smart :P
[15:44:35] <SolarNRG> a toxic zinc oxide vapour
[15:44:57] <SolarNRG> I went down the all electric road with microwaves
[15:45:00] <SolarNRG> It didn't work
[15:45:05] <SolarNRG> But i'm sure induction loop will
[15:45:08] <mrsun_> god damn uranium-235 is energy dence =)
[15:45:24] <Jymmm> mrsun_: lick it!
[15:45:38] <mrsun_> 79 500 000 MJ / Kg =)
[15:45:50] <mrsun_> compared to 47.2 MJ / Kg for gas :P
[15:46:01] <Jymmm> mrsun_: Hawt Damn, think amazon carries it?
[15:46:10] <mrsun_> i would rather have antimetter
[15:46:21] <mrsun_> theoretical is 180 000 000 000 MJ / Kg
[15:46:25] <Jymmm> I'd rather have anti-matter
[15:46:51] <mrsun_> anti-mater :P
[15:46:53] <mrsun_> matter
[15:46:57] <mrsun_> antimatter!
[15:46:59] <mrsun_> wth =)
[15:47:02] <Loetmichel> hmm, but a bit difficult to contain ;-)
[15:47:04] <mrsun_> metter? .. wth is that
[15:47:11] <Jymmm> dont matter either way =)
[15:47:24] <Jymmm> mrsun_: you lick the 235, didn't you?
[15:47:30] <Jymmm> licked
[15:47:33] <mrsun_> Jymmm, im not telling
[15:47:43] <Jymmm> I think you just did =)
[15:47:46] <Loetmichel> see if he glows in the dark... ;-)
[15:48:03] <Jymmm> Cool, dead glowing skin cells!
[15:48:11] <mrsun_> im so readioactive that people see me in x-ray
[15:48:21] <Jymmm> <rimshot>
[15:48:36] <mrsun_> wth is that ? :P
[15:48:45] <mrsun_> turned a babe upside down and took a shot from the rim ? ;P
[15:48:48] <mrsun_> (thinking rimjob)
[15:49:00] <Jymmm> mrsun_: http://instantrimshot.com/index.php?sound=rimshot&play=true
[15:49:08] <mk0> haha, SolarNRG is a troll from ##physics
[15:49:18] <mrsun_> Jymmm, oh :P
[15:49:19] <Loetmichel> hmm, i hop i havent bit off more than i can chew. anyone has milled slate from a Billard table?
[15:49:23] <mrsun_> thats far from what i was thinking
[15:49:24] <Jymmm> mk0: and #chemistry
[15:49:35] <mk0> :D no. he is really there
[15:49:39] <Loetmichel> i have to make the trophy stands out of an old Billard plate
[15:49:42] <Jymmm> mrsun_: perv
[15:49:49] <mrsun_> Jymmm, guilty as charged :/
[15:49:50] <Jymmm> mk0: I know, and in ##chemistry too
[15:50:00] <Jymmm> mrsun_: Keep up the good work =)
[15:50:28] <Jymmm> Ok, I'm off (in more ways than one) for a bit!
[15:50:44] <mrsun_> fingers fell off?
[15:50:52] <Loetmichel> mrsun_: rimschot= "tusch" in german
[15:50:55] <Loetmichel> -h
[15:51:10] <mrsun_> Loetmichel, and as im swedish you think that would help me how? :P
[15:51:24] <Loetmichel> oh, sorry, i somehow have sorted you to germany ;-)
[15:51:31] <mrsun_> haha =)
[15:51:59] <mrsun_> Loetmichel, cause of the rimshot thing? ... its stuff that i think germans could do im their dirty dirty movies
[15:52:16] <Loetmichel> and sorry again, my swedish is about 25 jears not used
[15:52:40] <mrsun_> va bar då kan jag säga lite vad jag vill här nu då ? :P
[15:52:44] <Loetmichel> and even then it was just the amount a gir can teach you on 2 weekends ;-)
[15:52:44] <mrsun_> bar->bra
[15:52:53] <Loetmichel> girl
[15:53:04] <SolarNRG> How am I a troll?
[15:53:12] <mrsun_> Maza-Trol! :P
[15:53:36] <SolarNRG> I actually build stuff, I actually test stuff, I video what I do and I share my videos with people, how is this trolling?
[15:53:59] <alex4nder> wut
[15:54:00] <mrsun_> SolarNRG, making magnet engines etc? :)
[15:54:08] <mrsun_> magnet generators
[15:54:30] <SolarNRG> I wasn't very successful at that either mrsun, my magnets were misaligned and acted more as dampeners rather than bearings
[15:54:49] <Loetmichel> hmmm...
[15:54:57] <SolarNRG> The positioning of your holes must be very precise
[15:55:11] <Loetmichel> i dont get how ANYONE with an egineering backgound can belive in overunity machines.
[15:55:22] <Loetmichel> +b
[15:55:23] <SolarNRG> I will admit I failed to build one
[15:55:26] <Loetmichel> grrr
[15:55:29] <Loetmichel> -b+n
[15:55:31] <SolarNRG> I will also admit I have failed to melt metal in a microwave
[15:55:36] <mk0> SolarNRG, you're furthermore a grammar troll! i explode
[15:55:48] <alex4nder> SolarNRG: you actually tried the microwave? what happened?
[15:55:50] * mrsun_ can see bits of mk0 flying by
[15:56:12] <SolarNRG> Alex yes
[15:56:12] <mrsun_> mk0, tried the meling glass trick ? :)
[15:56:22] <mrsun_> SolarNRG*
[15:56:33] <SolarNRG> http://www.youtube.com/watch?v=xlxbVKkm71E
[15:57:16] <SolarNRG> Just because I have failed to replicate someone's claim doesn't mean I'm right that it cannot be done
[15:57:20] <mrsun_> omg so brittish!
[15:57:23] <mrsun_> it hurts =)
[15:57:38] <alex4nder> SolarNRG: you ever heard the term 'keep it simple'?
[15:57:43] <alex4nder> it's a good default
[15:57:52] <SolarNRG> I like rube-goldberg methods
[15:57:57] <mk0> my butt melts
[15:58:21] <alex4nder> if it's complex, it's probably not going to work
[15:58:35] <Loetmichel> SolarNRG: if it comes to overunity machines: it CANT be done. Physics lawas are loaws, not suggestions
[15:58:38] <Loetmichel> laws
[15:58:48] <SolarNRG> TBH most of my channel are failed experiments, although I can be proud that I have been honest with my results
[15:58:49] <alex4nder> well
[15:59:00] <alex4nder> Loetmichel: they're 'rules' with REALLY high probability. ;)
[15:59:37] <SolarNRG> A lump of enriched plutonium seems to defy thermodynamics, at first glance it is a rock that is hot and continues to get hotter and hotter and will stay this way for years and years and years... Then we re-wrote science to account for "nuclear fission"
[16:00:02] <SolarNRG> One energy I firmly belive in is solar steam turbine
[16:00:13] <Loetmichel> alex4nder: as far as we know they are "written in stone". Someone who will build a overunity machine has to invent a WHOLE new physics first
[16:01:10] <Loetmichel> SolarNRG: IF you can build a magnetic monopole you CAN build your overunity machine...
[16:01:23] <Loetmichel> but taht is also not supposed to happen ;-)
[16:01:43] <mrsun_> but if you take a N/S magnet and cut it in half
[16:01:44] <alex4nder> watching too much Fringe, I think
[16:01:52] <mrsun_> shouldnt you have one north pole magnet and one south pole magnet then ?
[16:01:55] <SolarNRG> I can turn 48 neodymium magnets into a sort of monopolar arrangement by bolting them all down with 3mm bolts
[16:02:01] <Loetmichel> mrsun_: ... you get 2 NS magnets with half the size
[16:02:13] <mrsun_> aww .... im not stupid ;P
[16:02:23] <mrsun_> ok maybe i am .. but not that stupid
[16:02:30] <mrsun_> ofc you get one N magnet and one S magnet!
[16:02:30] <alex4nder> ...
[16:02:32] <mrsun_> silly
[16:02:39] <SolarNRG> http://www.youtube.com/watch?v=J68eplT9v2Y
[16:02:44] <SolarNRG> This was as close as I got
[16:02:48] <Loetmichel> *sigh*
[16:03:06] <mk0> mrsun_, as one greek said - the more i know the more i'm stupid
[16:03:45] <mrsun_> Loetmichel, sorry
[16:03:46] <mrsun_> =)
[16:04:01] <Loetmichel> mk0: that greek was right
[16:04:03] <mrsun_> damn im on a strange mood tonight ...
[16:04:21] <Loetmichel> SolarNRG: i dont see your problem
[16:04:29] <Loetmichel> magnetic bearings are simple
[16:04:31] <mrsun_> im more like, the more i know the more i just want to kill myself cause there is no meaning to be on this earth :P
[16:04:32] <mk0> yep. right/ i mean mrsun_ must not blame himself )
[16:05:03] <Loetmichel> but i would use some ring mangnets polarized axially
[16:05:14] <mk0> aand from futurama: there's no scientific consesus that life is important

[16:08:45] <alex4nder> wut
[16:08:54] <alex4nder> did someone just steal your keyboard, or did you change personalities?
[16:09:25] <mk0> SolarNRG, all scientist are of that kind
[16:09:28] <Loetmichel> whats DLA?
[16:09:38] <SolarNRG> Disability Living Allowance
[16:09:42] <Loetmichel> ah
[16:10:00] <SolarNRG> I have brain damage and I have autism and trichotillomania
[16:10:05] <SolarNRG> And PTSD and anxiety
[16:10:06] <alex4nder> SolarNRG: join the channel, and build a mill.
[16:10:15] <alex4nder> it'll give you something to build, that works
[16:10:22] <alex4nder> and then you can get all OCD on your spindle runout
[16:10:24] <Loetmichel> but since when is autims considered retarded and a brain damage?
[16:10:32] <alex4nder> and freak out about .001 of backlash
[16:10:35] <Loetmichel> or did you meand brain damage AND autism?
[16:10:35] <SolarNRG> The autism I got in 86
[16:10:41] <SolarNRG> The brain damage I got in 2006
[16:10:49] <SolarNRG> yes both separate conditions

[16:24:36] <Loetmichel> has anyone milled slate?
[16:24:40] <ReadError> yea alex4nder
[16:24:54] <Loetmichel> or was that question just not read?
[16:25:00] <ReadError> i realize it wouldnt be too bad to generate the code by hand
[16:25:08] <Loetmichel> SolarNRG: anyone
[16:25:10] <ReadError> but thats just the 1st piece, the others will be much more complex
[16:25:19] <Loetmichel> and a program to generate the richt toolpath ;-)
[16:25:27] <Loetmichel> right
[16:25:28] <SolarNRG> Isn't it going to cost like 4 thousand pounds for a good CNC mill?
[16:25:33] <ReadError> i think pfred or archivist cuts gears also?
[16:25:40] <Loetmichel> SolarNRG: depends.
[16:25:52] <Loetmichel> mine has cost me about 500$ in parts
[16:26:03] <Loetmichel> and mills planetary gears just fine ;-)
[16:26:10] <SolarNRG> :o
[16:26:20] <mk0> mine too
[16:26:25] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11702
[16:26:27] <SolarNRG> I love planetary gearboxes, you can have 2 motors or more driving a single rotor
[16:26:30] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11711
[16:26:36] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11714
[16:26:42] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11714
[16:26:56] <SolarNRG> That's beautiful
[16:27:19] <SolarNRG> I don't think I'm clever enough to build one, I'd rathe buy one
[16:27:36] <mk0> buy???
[16:27:46] <SolarNRG> yeah, save up for a year
[16:27:50] <Loetmichel> i had to make the planets 3 times 'cause i didnt took the shrinking of the hollow gear into accound when pressed into the box
[16:27:52] <mk0> that;s not even 4000 pounds
[16:27:58] <mk0> it's 20
[16:28:00] <alex4nder> ReadError: the only thing that's hard is making a nice cut.. if you're doing 1/4" aluminum or something, you can't just make those arcs in one pass.
[16:28:14] <alex4nder> ReadError: so you have to employ some type of material remove strategy
[16:28:24] <ReadError> alex4nder, maybe 1/8th inch aluminum
[16:28:32] <ReadError> but i got some plastics i can use also
[16:28:47] <alex4nder> ReadError: so I've been using a edge-milling strategy.. and keeping the chip load at like .002"
[16:28:52] <ReadError> i can cut the same path 3x ?
[16:28:55] <ReadError> at different depths
[16:29:04] <alex4nder> that's one strat, and it works
[16:29:05] <Loetmichel> ReadError: or 100 times...
[16:29:06] <Loetmichel> ;-)
[16:29:16] <alex4nder> but I like taking off 'tall' small pieces.
[16:29:35] <alex4nder> so I run the cutter at the maximum depth, and shave off small pieces at a time
[16:29:38] <alex4nder> and I move at like 30 IPM
[16:29:45] <ReadError> pycam does the outside in the big hole fine
[16:29:54] <ReadError> but it doesnt want to 'drill' the other ones for some reason
[16:30:01] <alex4nder> just leave them out
[16:30:08] <alex4nder> and add them to the file manually
[16:30:11] <ReadError> yea i could do another path for that
[16:30:11] <alex4nder> as a peck drill routine
[16:30:11] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12760
[16:30:17] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12766
[16:30:22] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12773
[16:30:52] <Loetmichel> that was 300 times around ;-)
[16:30:56] <alex4nder> yah
[16:30:58] <alex4nder> that's one approach
[16:31:04] <alex4nder> I've been doing this..
[16:31:48] <alex4nder> Loetmichel: http://www.youtube.com/watch?v=ELfONtG_Zkk#t=1m
[16:32:01] <alex4nder> that's at .20 DoC
[16:32:30] <alex4nder> the chips were really consistent, and the machine really liked the constant load
[16:32:44] <Loetmichel> alex4nder: http://www.cyrom.org/pce/connectbar.avi
[16:33:30] <Loetmichel> http://www.cyrom.org/pce/lochknabbern.avi
[16:34:44] <alex4nder> cool
[16:35:15] <alex4nder> now we just need an opensource replacement to VoluMill, HyperMill, or SurfCAM. :P
[16:36:26] <alex4nder> ok
[16:36:35] <alex4nder> I'm going to go try to get 100 IPM out of my taig
[16:36:51] <ReadError> hmm
[16:36:56] <ReadError> i havnt tried any of those yet
[16:37:02] <ReadError> they have fully functional trials?
[16:37:20] <Loetmichel> alex4nder: hmmm, thats 2540mm/min, right?
[16:37:23] <Loetmichel> sounds easy
[16:37:46] <alex4nder> Loetmichel: easier said than done
[16:37:53] <alex4nder> most people run their taigs at < 60
[16:38:02] <alex4nder> w/ steppers
[16:38:11] <Loetmichel> the mini mill i have build does 3m/min if driven with 40V
[16:38:39] <Loetmichel> atm i have only 32V supply, so the maximum speed is about 2,5m/min
[16:38:59] <Loetmichel> and my steppers have only 1A/phase
[16:39:28] <Loetmichel> but: my mill has ball bnearings on round steel as ways
[16:39:36] <Loetmichel> not V-shape glide things
[16:40:05] <alex4nder> these screws are 20 TPI
[16:40:50] <ReadError> should i order some drill bits instead of cutting the holes with an endmill ?
[16:40:54] <r00t4rd3d> how can i cut tslot straight with a hacksaw?
[16:41:07] <alex4nder> r00t4rd3d: lube the saw with butter
[16:41:15] <ReadError> sounds like you need a router?
[16:41:21] <syyl_> tslot? hacksaw?
[16:41:26] <r00t4rd3d> lol
[16:41:29] <alex4nder> ReadError: endmill on that is fine
[16:41:31] <syyl_> there must be something in the air today
[16:41:57] <alex4nder> yah
[16:42:09] <alex4nder> it's cinco de mayo, everyone is drunk
[16:42:33] <r00t4rd3d> i dont drink
[16:42:44] <syyl_> you can cut a tslot with a hacksaw, if you exchange it with a milling machine and a tslot cutter...
[16:43:24] <r00t4rd3d> its only 1x1inch
[16:43:29] <alex4nder> or you could move to a buddhist monastery and bring the metal and a bastard file with you
[16:43:36] <alex4nder> and spend some time.. alone.
[16:44:01] <r00t4rd3d> i can probably do it in a vise
[16:44:16] <r00t4rd3d> and use the vise as my guide
[16:44:19] <alex4nder> alright.
[16:44:26] <syyl_> sell the hacksaw, take the money and go to a machineshop
[16:44:29] <syyl_> Oo
[16:44:33] <alex4nder> what is this for?
[16:44:41] <r00t4rd3d> just a spacer
[16:45:06] <alex4nder> why does it need to be a t-slot then?
[16:45:24] <r00t4rd3d> cause i have an extra piece collecting dust
[16:46:16] <ReadError> alex4nder, how often do you lube the leadscrews?
[16:46:25] <alex4nder> whenever they're dry
[16:46:29] <r00t4rd3d> lol
[16:46:35] <ReadError> pretty hard to get to em
[16:46:46] <alex4nder> you mean X?
[16:46:49] <ReadError> i need a longer needle i think
[16:46:49] <ReadError> yea
[16:46:53] <alex4nder> yah, it blows
[16:48:34] <alex4nder> ok, bbl
[16:50:31] <r00t4rd3d> ReadError, goto the hardware store and buy a grease nipple and make a block
[16:51:20] <ReadError> still impossibru to get to
[16:51:32] <r00t4rd3d> mine are easy
[16:53:17] <gene__> Hi guys, problem with g76 after I made close loop spindle speed work. It goes to a point at about the first cut depth, and sits forever waiting for a spindle index, which is there
[16:54:04] <gene__> Any idea what I might have messed up in the hal file that is stopping that?
[17:02:01] <alex4nder> r00t4rd3d: how would he make a block to grease the leadscrews on the underside of his table?
[17:10:13] <ReadError> so, i was talking with my dad
[17:10:21] <ReadError> he said they have whole bins of scrap metal at work
[17:10:25] <ReadError> some large pieces
[17:10:35] <ReadError> from f35 parts
[17:10:41] <ReadError> hes gonna grab me some ;)
[17:10:49] <alex4nder> nice
[17:10:49] <ReadError> surely they got some decent aluminum and such
[17:11:18] <ReadError> on problem is i wouldnt know what kind of aluminum it is
[17:11:39] <alex4nder> who cares
[17:11:44] <alex4nder> unless you're welding
[17:11:49] <alex4nder> or making critical parts
[17:11:51] <ReadError> ya
[17:11:52] <jdhNC> free is free.
[17:12:04] <alex4nder> my aluminum is the shitty household kind you get at Ace
[17:12:05] <ReadError> most aluminum i can cut at about the same rate?
[17:12:08] <alex4nder> it's like milling gummy bears
[17:12:30] <ReadError> i got a 36" of 1" bar
[17:12:36] <ReadError> i can cut a bunch of goodies with that
[17:12:39] <ReadError> 6061 i think
[17:12:40] <alex4nder> ReadError: I think you can pretty much crank your spindle speed up as high as you want.. the one worry you'll have is chips welding to your endmill
[17:12:43] <alex4nder> and smearing.
[17:12:53] <alex4nder> so a little lube goes a long way
[17:13:27] <ReadError> coolant would be nice
[17:13:27] <ReadError> but ide make a mess of it
[17:17:57] <alex4nder> ReadError: I'll put up pics of my new rig and filter.
[17:19:20] <ReadError> ooo nice
[18:12:08] <toastydeath> gummy aluminum is the biggest problem at low feed rates
[18:12:59] <toastydeath> finishing gummy aluminum takes a very sharp tool with a generous nose radius
[19:33:40] <KimK> gene__: Did you get it figured out? Would you like to pastebin your hal file?
[20:23:48] <r00t4rd3d> mommy?
[20:24:33] <ReadError> said knock you out
[20:27:05] <r00t4rd3d> i actually put in alot of time today on my table
[20:27:30] <r00t4rd3d> boring stuff but still stuff
[20:28:01] <pfred1> I put in a lot of time trying to sleep but i kept on getting acid reflux
[20:28:14] <r00t4rd3d> eat some hot peppers
[20:28:17] <pfred1> so here I am!
[20:29:24] <ReadError> im wasting alot of time trying to generate this dang toolpath
[20:30:15] <pfred1> ReadError I've heard it said first you get good, then you get fast
[20:32:42] <r00t4rd3d> worked the other way around for me
[20:32:51] <ReadError> pfred1
[20:32:54] <ReadError> my model is good
[20:33:00] <ReadError> the apps that are free, arent ;/
[20:33:11] <ReadError> i had high hopes for pycam too ;(
[20:33:39] <pfred1> G code generation is spotty on Linux it seems
[20:34:22] <ReadError> indeed sir, indeed
[20:34:28] <pfred1> I was just checking out reprap did you know that stuff runs on java?
[20:34:41] <ReadError> yea, and usb
[20:34:49] <pfred1> how in the heck they get java to do RT I'll never know
[20:35:01] <ReadError> well, its balls slow
[20:35:22] <pfred1> they really don't know what they're doing do they?
[20:35:30] <ReadError> well
[20:35:37] <ReadError> java is pretty bloated
[20:35:44] <ReadError> but its fast to bang out code in as well
[20:35:57] <pfred1> oh come on I just watched a video where they made a coat hanger and all I could think was they could have picked up a stick in their yard and nailed it to the wall
[20:36:19] <pfred1> it'd have looked better too :)
[20:58:05] <Jymmm> a reprap hanger?
