[02:10:08] <Deejay> moin
[02:13:28] <Einar1> Good morning.
[02:22:09] <Vq> Good morning
[02:24:35] <Deejay> good morning vietnaaaaaaaaaaaam ;)
[02:24:45] <Loetmichel> Deejay: wrong
[02:25:12] <Loetmichel> "gooooooood moooooooooooooooorning viet^WChannel!"
[02:25:13] <Loetmichel> ;-)
[02:25:57] <Loetmichel> and you're not robin williams ;-)
[02:27:03] <Jymmm> And if either of you are going to do robin williams, you can't forget his early stuff.... A NY Echo.... 'Hello up there'... "SHUT THE FUCK UP"
[02:31:09] <Einar1> I just got in my 2.2KW spindle from China yesterday. Measuring the TIR the needle did not move visibly on a 0.01mm indicator. :-)
[02:31:38] <Loetmichel> Jymmm: are you also a "morgenmuffel" (morning grouch)?
[02:31:40] <Loetmichel> ;-)
[02:31:59] <Loetmichel> Einar1: where did you measure?
[02:32:46] <Jymmm> It's midnight
[02:32:49] <Einar1> I put a rod in the collet and measured appx. 30mm from the collet holder.
[02:33:02] <Loetmichel> directly at the cone of the spnidle, or with a mill bit shaft put in the ER collet and measured some distance from the collet on the shaft?
[02:33:22] <Loetmichel> oh, that is great then
[02:33:44] <Loetmichel> i would have expected at least 0,02mm there.
[02:34:23] <Einar1> Measuring the concentricity of the spindle shaft vs. the outside of the motor is not that grat though. Concentric at the upper end, while 0.1mm off at the collet end.
[02:35:09] <Loetmichel> that is not a problem
[02:35:17] <Einar1> So it is not good enough that the hole in the spindle holder is trammeled.
[02:35:30] <Loetmichel> usually you have to andjust the spindle to the z axis anyways
[02:35:48] <Einar1> Not a big problem, no. And really not expected either.
[02:36:11] <Loetmichel> i had some aluminium tape as "hasberg foil" underneath the holders to adjust it on mine
[02:36:35] <Einar1> But since I have these fancy measuring devices i must use them for something. Ehh?
[02:36:50] <Loetmichel> i would check the connections in the plug of the spindle though
[02:36:59] <Einar1> Hasberg foil?? Was ist das?
[02:37:16] <Loetmichel> mine hat gn NOT connected, instead they used blue as a Phase ;-)
[02:37:25] <Loetmichel> ( so no earth)
[02:37:40] <Loetmichel> thin steel foil used to level things
[02:38:13] <Loetmichel> cmes in varouls thicknesses and usually small stips coiled up
[02:38:21] <Loetmichel> comes
[02:38:27] <Einar1> The plug have only 3 prongs. So at least they do not fake it. I already found a 4-prong plug and receptacle at work that I will use. It also is IP67.
[02:38:55] <Einar1> (IP67 = Water can get in, but not out again.)
[02:39:16] <Loetmichel> i have two 800W watercolled spindles
[02:39:23] <Loetmichel> so water is already in ;-)
[02:39:46] <Einar1> Do you use plain water or (car) coolant?
[02:40:18] <Loetmichel> Einar1: mix of both
[02:40:47] <Einar1> I bought the 2.2KW with 4 bearings mostly because it's more sturdy. Not because I need the power.
[02:42:01] <Loetmichel> https://www.youtube.com/watch?v=a9Ov69t0uwo <- my setupo at home
[02:42:23] <Loetmichel> the "water" is now red as i put in a liter of car coolant concentrate ;-)
[02:42:42] <Einar1> The spindle spins freely without any noise or uneven feel. I thought of clamping a microphone on it while running in, but my (magnetic) pickup microphones does not stick to stainless.
[02:43:07] <Einar1> I would be curious to see the FFT plot while running.
[02:44:53] <Einar1> I have a retired CPU cooler that I was thinking of connecting up to the spindle. It's pretty compact and closed loop.
[02:46:17] <Loetmichel> normally not needed
[02:46:32] <Einar1> I do regret not buying a set with the clamp for the spindle though. But this seller did not have that. I can never ever make the clamp as cheap as what the chinese sell them for.
[02:46:35] <Loetmichel> the bucket in my case provides ample dissipating surface
[02:46:54] <Loetmichel> the Temperature at the cooling water doesent get above 35°C
[02:47:20] <Loetmichel> i made the clamp with the CNC mill ;-)
[02:47:39] <Einar1> Chicken & egg ?
[02:48:03] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12518
[02:48:19] <Loetmichel> i had a proxxon BFW400 spindle on it beforehand ;-)
[02:48:23] <Loetmichel> BFW40
[02:48:25] <Einar1> I could. I have a big mill. But no thick aluminum sheet.
[02:48:35] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12527
[02:48:40] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12530
[02:48:50] <archivist> local scrap yard is where I get aluminium
[02:48:50] <Einar1> Ahh... a small chicken. ;-)
[02:48:58] <Loetmichel> ??
[02:49:28] <Einar1> .. laying an egg for the bigger chicken.
[02:49:33] <Loetmichel> ah ;-)
[02:50:23] <Einar1> Did you make the whole mill? It does not look like most I've seen.
[02:50:42] <Loetmichel> yeah, its completely selfbuild
[02:50:51] <Einar1> Nice! :-)
[02:51:14] <Einar1> Is it a weldment?
[02:51:24] <Loetmichel> not a single weld
[02:51:30] <Loetmichel> all screwed together
[02:51:56] <Einar1> Ahh. We'll call it a screwment.
[02:51:59] <Loetmichel> and the 10mm round steel bars are glued in the v-grooves
[02:53:56] <Einar1> And ball bearings against the bars?
[02:54:07] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14034
[02:54:09] <Loetmichel> yes
[02:55:24] <Einar1> And the screw? Is it ACME in acetal or other plastic nut?
[02:56:05] <Loetmichel> german 10mm*3mm "trapezgewinde" in acetal, right
[02:56:46] <Loetmichel> the POM nut is slit in half to get the play out
[02:57:09] <Einar1> Being nice to your neighbours too. -> http://www.cyrom.org/palbum/main.php?g2_itemId=12560
[02:57:34] <Loetmichel> hrhr, more being nice to the stepper drivers
[02:57:58] <Loetmichel> without the ferrite bead and the sheild i couldnt get the machine to NOT loose steps as soon as the spindle had started
[02:58:31] <Einar1> But try to keep the (ground) pigtail as short as possible. Even better is 360degrees clamping to the ground bar.
[02:58:56] <Loetmichel> i shield computers for a living
[02:59:05] <Loetmichel> against eavesdroppnig
[02:59:10] <Loetmichel> i know that i am doing
[02:59:30] <Loetmichel> and the shield is 360° clamped at the spindle end
[02:59:40] <Einar1> And better not to ground the shield at the motor end. This is probably against your Tempest thinking. But it can create ground loops.
[02:59:55] <Loetmichel> i know
[03:00:03] <Loetmichel> but it works good this way
[03:00:19] <Loetmichel> my center point of ground is the machine, not the VFD
[03:01:23] <Loetmichel> and the moving parts are grounded by seperate wires, i am not relying on the ball earings for that ;-)
[03:01:25] <Einar1> You probably have a pretty even ground regime because of your work. Ground everything that looks metallic to the common ground point?
[03:01:35] <Einar1> Exactly!
[03:01:44] <Loetmichel> right
[03:01:45] <Loetmichel> ;-)
[03:02:44] <Einar1> It's also in my line of work. "Do you have fillings in your teeth? OK, then ground them!!"
[03:02:52] <Loetmichel> harhar
[03:03:17] <Loetmichel> as far as emi goes: i made the discovery that a weak ground is better than a zero ohm one
[03:03:25] <Loetmichel> for amping
[03:03:30] <Loetmichel> damping
[03:03:55] <Loetmichel> so the fillings are grounded by your flesh bettter than by a wire ;-)
[03:04:35] <Loetmichel> i could haave made a shielded case for the steper drivers instead of damening the emi from the spindle
[03:04:36] <Einar1> I tend to emit more acoustic noise than EMI.
[03:05:29] <Einar1> I have a VFD filter on the shelf in case needed.
[03:05:38] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12808 <- that is the back of the MIll ;-)
[03:06:22] <Loetmichel> there is some potential for shielding... i left that for later ;-)
[03:06:59] <Einar1> You have access to EMC lab, don't you? It would be interesting to see the emission properties of the "Fjung Yang" VFD.
[03:07:04] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12811 <- front
[03:07:14] <Loetmichel> i have access to tow labs
[03:07:21] <Loetmichel> but i dont want to know that
[03:07:34] <Loetmichel> i already had fun with a 50W batter charger
[03:07:53] <Loetmichel> laying on my desk, charging a drill battery
[03:08:03] <Loetmichel> 10 meters from the measurement chamber
[03:08:25] <Einar1> I just unpacked it. Only test so far was shaking it. No rattles, nothing fell out. ;-)
[03:08:31] <Loetmichel> colleague omens the chambers door: SA goes to overload from 10khz to 10ghz
[03:08:36] <Loetmichel> "WTF?!?"
[03:08:40] <Loetmichel> opens
[03:09:13] <Einar1> ?? That means your chamber leaks?
[03:09:45] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14751
[03:09:49] <Loetmichel> this lottle fucker
[03:10:07] <Einar1> Uhh? KaBooom!! ??
[03:10:42] <Loetmichel> no, that means the chamber is good, but openening the chambers door let enough emi from that charger in that the Analyzer has gone to overload
[03:10:49] <Loetmichel> and that from 10 meters distance
[03:11:17] <Loetmichel> kaboom? why?
[03:11:31] <Loetmichel> because i pryed open a lithium battery?
[03:11:35] <Loetmichel> wimp! ;-)
[03:11:56] <Einar1> OK I thought it was opened by the charger.
[03:12:32] <Loetmichel> no, that was a test if the battery itself is still good
[03:12:58] <Loetmichel> the - tab wasnt welded to the sell, so it did not work inside the shell
[03:13:13] <Loetmichel> bought two flashlights with 4 of these batterys
[03:13:33] <Loetmichel> 2 not working at all, the other two had 300 and 400mAh instead of 3000
[03:13:37] <Einar1> So are those batteries like russian dolls? A case within a case. I never opened one.
[03:13:46] <Loetmichel> still a good deal for 12 eur each ;-)
[03:14:12] <Loetmichel> no, the battery itself there is just a wrap of metal foil and electrolyte ;-)
[03:14:51] <Einar1> I know a guy in UK that offered me a BIG bunch of free LiIon cells. But they cannot be shipped without a stack of papers. ;-(
[03:14:51] <Loetmichel> intense "cherry" stench when opened ,-)
[03:15:34] <Loetmichel> have him pack them in 6 packs and send in seperate packages ,-)
[03:16:23] <Einar1> I think even then it would go against the rules. Besides becoming rather expensive.
[03:16:28] <Loetmichel> iirc the paperwokr is only needed above a certain thereshold of lithium mass inside the cells
[03:16:49] <Loetmichel> per package
[03:17:42] <Loetmichel> i just paid 7 eur per cell for four real 2900mah 18650 cells
[03:17:53] <Loetmichel> and they live up to the promise.
[03:17:54] <Einar1> I have another option. A friend living just 3Km away repairs robot mowers. Usually many cells in a dead package is good.
[03:18:13] <Loetmichel> unlike the chinese blue ones ;-)
[03:19:21] <Loetmichel> btw: althoug the batteries are bad and they have some issues with quality control: these flashloghts are really great: http://www.cyrom.org/palbum/main.php?g2_itemId=14733
[03:19:29] <Einar1> And I also know a guy running a tow truck + car crushing facility. I'm just waiting for a Tesla crash. ;-)
[03:19:54] <Loetmichel> 12 eur each for this: http://www.cyrom.org/palbum/main.php?g2_itemId=14742
[03:20:23] <Loetmichel> from top to bottom: lamp off, lamp on wide, lamp on maximum zoom
[03:20:49] <Loetmichel> and it fits the trousers pocket ;)
[03:21:34] <Loetmichel> hrhr, i think tesla will buy back the pile of steel that resuilts in a crahs
[03:22:03] <Loetmichel> and if it were only to prevent bad press from a burning car compactor ;-)
[03:22:15] <Einar1> Speaking of.. Once I felt like my pocket was burning! I forgot that I put a battery in my pocket. And there already was a bunch of keys there. Ouchhh!
[03:22:22] <Loetmichel> ouch
[03:22:54] <Loetmichel> did that on pourpose with 2 9V e-blocks a couple of times as poor mans pocket heater
[03:23:09] <Loetmichel> just plug them together for about 2 hrs of warmth ;-)
[03:23:41] <Einar1> Boiled eggs? :-) :-)
[03:23:41] <Loetmichel> BATETRIES, bot accumilators, or tyour pocket will burn ;.-)
[03:24:00] <Loetmichel> <- sorts his fingers ;-)
[03:24:02] <Einar1> With a sausage.
[03:24:55] <Loetmichel> the 9V alkaline blocks can deliver about 1A at max (high inner resistance) so you have about 18W heating in the pocket
[03:25:14] <Loetmichel> just enough to get it cozy, not enough to burn anything ;-)
[03:26:20] <Einar1> It's a beautiful day. I think I'll go and pull some weed out of the ground and see if there is a lawn somewhere underneath.
[03:28:35] <Loetmichel> hrhr
[03:28:48] <Loetmichel> i will drive 2300km to a multicopter meeting now
[03:28:52] <Loetmichel> 200km
[03:30:22] <Einar1> Have a nice trip.
[03:41:29] <Valen> 200km is better than 2300km ;->
[03:45:33] <Loetmichel> Valen: for 2300km i would take a plane
[03:45:37] <Loetmichel> to lazy
[03:45:39] <Loetmichel> ;-)
[03:45:41] <Loetmichel> +o
[04:28:01] <miss0r> This morning I was offered a Roland PNC-3100 complete with software & Lisences for ~1200USD. It has only been used for aprox 4 hours, and everything is shining new (It has been in warm dry storage for 4 years). Is this a good offer? is the Roland PNC-3100 any good? (I have no experience with this machine what so ever)
[04:29:00] <Jymmm> to do what?
[04:29:21] <miss0r> PCB & plastic milling
[04:29:41] <miss0r> I am basicly wondering if this machine is worth the money
[04:31:28] <Jymmm> Roland has always been propritary in the software
[04:31:55] <Jymmm> So a retrofit may be in oder to move away from that or if you need to upgrade/replace parts later on.
[04:32:23] <miss0r> Indeed. Can you tell me anything about this machine? is it a good offer?
[04:32:36] <Jymmm> XYZ woring area is 9x6x6 inches so not very big
[04:33:21] <Jymmm> Tooling I think it uses by default is more specialized
[04:33:41] <Jymmm> Not like you can chuck up a 1/4" bit iirc
[04:34:09] <Jymmm> 6mm EDC-24 collet it looks like.
[04:34:27] <miss0r> So I can only mount 6mm bits?
[04:34:50] <Jymmm> They are basically a jewlery/engravers type machine, good quality
[04:36:01] <miss0r> well, the plastic I am working on is basically engraving signs ect. and if it can do jewlery it can certainly do pcbs ?
[04:36:01] <Jymmm> http://www.zelkovaltd.com/Plotterworld/store/stock/Roland/Brochure/PNC-3200.htm
[04:36:21] <miss0r> the one I am looking at is a 3100
[04:38:05] <Jymmm> http://www.manualslib.com/manual/604438/Roland-Pnc-3100.html?page=3#manual
[04:39:19] <miss0r> Indeed, i've read the manual. But I am having a hard time finding any of these for sale online, so I have no idea if I am being overcharged. What is your opinion?
[05:03:41] <Einar1> Used 4 hours? Then it's cheap. If it will do what you want it to do is something you have to judge. If not, it's an expensive exibit piece. ;-)
[06:28:26] <_methods> http://axiomtek.com/products/ViewProduct.asp?view=1112
[07:28:35] <jdh> anyone making anything cool and/or interesting?
[08:07:57] <archivist> I am waiting for the next interesting thing to do, does that count?
[08:10:43] <syyl> just made a dividing head ;)
[08:10:44] <syyl> http://gtwr.de/web/wp-content/uploads/2014/02/pro_div_198.jpg
[08:12:02] <jdh> syyl: nice!
[08:12:45] <syyl> :)
[08:12:49] <syyl> made from this kit
[08:12:50] <syyl> http://www.hemingwaykits.com/acatalog/Versatile_Dividing_Head.html
[08:17:57] <CaptHindsight> been trying to find uses for those cheap routers besides recycling them for metals, here's a possibility http://www.youtube.com/watch?v=jhQJDfmBmb0
[08:18:42] <archivist> syyl, I have the castings for that (for many years)
[08:19:45] <archivist> what not cnceed
[08:24:47] <narogon> hi
[08:25:59] <narogon> if I want to recompile some changes i've made in .../src/emc/usr_intf/halui.cc
[08:26:08] <narogon> is just enough ./configure and make???
[08:29:42] <cradek> assuming you already configured and built before -- make will build just the necessary things
[08:29:53] <cradek> you only need to configure once
[08:31:02] <JT-Shop> syyl, very nice
[08:31:16] <narogon> ok thank you cradek!!
[08:31:56] <archivist> I hope syyl got better worms and wheels than I did
[10:00:00] <malcom2073> Unexpected realtime delay on RT thread 1, crap! heh
[11:50:16] <fogl> hello everybody... is there a way to read the current rt_timer configuration. I would like to know if it runs in oneshot_mode or in periodic_mode. What rt_timer_mode is required for running linuxcnc?
[11:56:49] <IchGuckLive> hi all
[11:58:09] <IchGuckLive> fogl: if you run the linuxcnc live cd it will install the kernel and the mode you need to
[11:59:32] <fogl> i know :) but i would like to know which mode is this
[11:59:59] <IchGuckLive> let me check it on a real mashine
[12:00:24] <fogl> i have the machine with linuxcnc also, but i dont know how can i check this
[12:00:57] <fogl> when i run latency test it says it runs in one_shot mode
[12:01:54] <IchGuckLive> this is it
[12:02:30] <IchGuckLive> this gives you the known ns trigger we all like
[12:02:43] <fogl> i was talking about rtai latency test. ..and i assume the linuxcnc latency test also runs in one-shot mode.... but what i dont understand is why do i have to set the servo_period to a value equal to base_period*n
[12:03:49] <IchGuckLive> the servo period is used to check IO not realy needed in the movement trigger base
[12:04:18] <IchGuckLive> you simply do not need to check all the IO on every interpreter loop
[12:04:48] <IchGuckLive> fogl: on a stepper mashine it is also not needed as the trigger is slow
[12:05:03] <IchGuckLive> slow means about 500ns
[12:05:19] <IchGuckLive> lowest i use 5000
[12:05:58] <IchGuckLive> fogl: wat is your goal to meat SERVO on fast mashine
[12:06:11] <IchGuckLive> or standard milling plasma
[12:06:18] <fogl> no, just study linuxcnc and rtai
[12:06:52] <Jymmm> World's Simplest Soft Latching Power Switch https://www.youtube.com/watch?v=Foc9R0dC2iI
[12:07:23] <IchGuckLive> fogl: where are you in the world im in germany
[12:07:41] <fogl> slovenia
[12:08:19] <IchGuckLive> for speeding up your system base and servo period is normaly not a good start
[12:11:05] <fogl> what i dont uderstand is why the servo_period has to be equal to integer*base_period. This implies the linuxcnc uses rt_timer in periodic mode
[12:11:44] <IchGuckLive> no you need a fix count
[12:11:55] <IchGuckLive> to get a realtime integer check
[12:12:32] <IchGuckLive> lets say EXample
[12:12:44] <IchGuckLive> Servo 1Mio Base 100k
[12:12:55] <IchGuckLive> so interpreter TR lookup is 10
[12:13:34] <IchGuckLive> you will find a Realtime error if the servo period triggers and the base counter is not at 10
[12:14:03] <IchGuckLive> actely it is at 9 as started at 0
[12:14:24] <IchGuckLive> so the system check is confirmed and the step will take place
[12:14:32] <fogl> can i set base period to 123k and servo to 1M
[12:14:58] <IchGuckLive> base at 123k is a very< badpc
[12:15:30] <IchGuckLive> yes you can you will see in some movements a Realtime fail on screen but the mashine will do the step
[12:16:20] <IchGuckLive> fogl: the 123k in the stepconf will not be regionised you need to do this manuell
[12:16:48] <IchGuckLive> i assume you said the parport reset timing in hal aso up
[12:16:58] <IchGuckLive> at least 6k
[12:17:31] <IchGuckLive> fogl: please hit my nickname
[12:17:49] <fogl> i did
[13:17:07] <IchGuckLive> Loetmichel: did it rain at your home
[13:17:23] <IchGuckLive> here we got less then 1liter in the last week
[13:18:06] <IchGuckLive> all clouds re burning away in Baddürkheim region
[15:19:00] <Jymmm> PCW: ping

[16:41:12] <CaptHindsight> and I was just thinking about making an updated motorized skateboard
[16:42:06] <SpeedEvil> I have a design for a hoverboard.
[16:42:41] <SpeedEvil> It's ~30kg, 0.6.1.2*0.3m or so (folded) unfolds into a square, and can ascend to 4km or so.
[16:42:56] <SpeedEvil> Peak accelleration is 2G, take-off power is 300kW
[16:43:38] <CaptHindsight> it doesn't count if you just mount a deck on top of a fighter jet :)
[16:43:59] <SpeedEvil> Err - no - this is carryable.
[16:44:14] <SpeedEvil> Well - luggable.
[16:44:41] <SpeedEvil> Basically a closely packed array of ducted fans.
[16:44:53] <CaptHindsight> pretty dense power 10KW/Kg
[16:45:08] <SpeedEvil> 100 fans at 3kW spinning at 50000RPM may be rather loud though.
[16:45:30] <SpeedEvil> Lithium-ion batteries have ridiculous energy density. If you're OK with them only lasting 4 minutes or so.
[16:45:45] <SpeedEvil> ^a charge
[16:46:30] <CaptHindsight> what the glide angle like?
[16:46:49] <SpeedEvil> Exactly the same as a brick, unpowered.
[16:46:51] <CaptHindsight> rock or kite?
[16:47:27] <SpeedEvil> It's going to fall at about 90MPH I think.
[16:47:40] <CaptHindsight> $1499 total yikes!
[16:48:21] <CaptHindsight> and only 4-6mi range
[16:49:36] <SpeedEvil> I question if you'd really want to ride it long distances though. It's not as if you're gonna commute on it.
[16:49:39] <CaptHindsight> I used to get ~1mi per oz of 10% nitromethane and gasoline
[16:49:58] <SpeedEvil> 'The frame of Onewheel is CNC machined from solid billet 6061 aluminum. This creates the lightest and strongest vehicle.'
[16:50:11] <SpeedEvil> Right - that's why F1 cars are made out of machined solid aluminium.
[16:50:18] <CaptHindsight> heh
[16:50:49] <CaptHindsight> well if they tried carbon fiber it would be a $15K skateboard
[16:51:36] <SpeedEvil> CF isn't really that expensive.
[16:51:41] <SpeedEvil> But the design probably is.
[16:51:50] <SpeedEvil> Al isdamn easy
[16:52:48] <SpeedEvil> I suspect you could make it quite a lot lighter with two small wheels.
[16:52:52] <SpeedEvil> I mean split it
[16:53:23] <CaptHindsight> I think they just made a proto for fun and it ended up being popular
[16:53:33] <SpeedEvil> yeah
[16:53:54] <CaptHindsight> it could use lots of improvement
[16:54:06] <CaptHindsight> they raised $600k
[16:54:09] <SpeedEvil> It'sgoing to be decent on grass, I guess.
[16:55:15] <SpeedEvil> The single large wheel has obvious terrainplusses
[16:56:48] <CaptHindsight> if the back was a bit longer so that you could use it as a kicktail....
[16:57:01] <CaptHindsight> I could see getting some air with that
[16:57:34] <CaptHindsight> have the wheel coast when it's not on the ground

[17:26:45] <CaptHindsight> do any of these guys even read Machine Design?

[17:28:43] <skunkworks_> http://youtu.be/HPzow8L1dxw
[17:33:06] <CaptHindsight> skunkworks_: faster and also better blending or just faster?
[17:34:36] <skunkworks_> faster because of the new lookahead

[18:46:08] <humble_sea_bass> this is too upsetting for a thursday
[18:46:12] <humble_sea_bass> wtf are you doing to me
[18:48:13] <MrHindsight> lol
[18:51:39] <MrHindsight> been battling with the Automation Direct PLC programming tools today
[18:52:22] <humble_sea_bass> those the PLCs that look like legos
[18:52:38] <MrHindsight> I swear does anyone that needs to get anything done quickly ever talk to their devs?
[18:53:50] <MrHindsight> they have a whole range from bricks to multiple slots
[18:54:41] <MrHindsight> http://www.automationdirect.com/adc/Shopping/Catalog/Programmable_Controllers
[18:56:43] <humble_sea_bass> what wrong with their tools
[18:59:42] <zeeshan> micrologix allen bradley
[18:59:45] <zeeshan> are very cheap!
[18:59:51] <zeeshan> er
[18:59:56] <zeeshan> rockwell / allen-bradley
[19:00:06] <zeeshan> you can get a 16 i/o one for like $100
[19:00:09] <zeeshan> on ebayy
[19:10:24] <MrHindsight> zeeshan: same for these KOYO/DirectLogic
[19:10:46] <zeeshan> ah i see
[19:10:50] <MrHindsight> had the software already
[19:10:59] <zeeshan> i downloaded rs-logix
[19:11:06] <zeeshan> was a pain in the ass to find a long trime ago
[19:11:40] <MrHindsight> I'm using it on your lathe
[19:13:14] <zeeshan> :D
[19:13:18] <zeeshan> for what
[19:15:03] <revo14> hello, linuxcnc can run in a laptop hp v6000? with that ports? or just port parallel
[19:17:01] <MrHindsight> zeeshan: on/off, fwd/rev and blinkenlights
[19:17:16] <zeeshan> ah cool
[19:17:23] <zeeshan> my machine did that with contactors
[19:17:25] <zeeshan> not plc
[19:17:46] <MrHindsight> the panel on this one was a mess and missing stuff
[19:17:54] <zeeshan> same with mine man
[19:17:55] <zeeshan> when i first got it
[19:18:04] <zeeshan> it was a nightmare :P
[19:18:11] <zeeshan> but it ended up only needed an e-stop button
[19:18:14] <zeeshan> and it all worked!
[19:18:21] <zeeshan> sadly it was the last thing i checked
[19:18:27] <zeeshan> so it took 2 days to figure it out
[19:18:28] <MrHindsight> the panel was for 1-phase not 3 phase
[19:18:35] <zeeshan> mine was 1 phase too
[19:18:50] <zeeshan> i recently converted to 3 hp 3 phase
[19:19:12] <zeeshan> MrHindsight: damn it
[19:19:16] <zeeshan> i coulda sent you my whole 1 phase control
[19:19:19] <zeeshan> i'm using none of it
[19:19:23] <zeeshan> its collecting dust in the basement
[19:19:33] <MrHindsight> no biggie
[19:19:35] <zeeshan> including the box
[19:19:38] <zeeshan> if you do one again
[19:19:39] <zeeshan> please ask
[19:19:41] <zeeshan> ill send it
[19:19:42] <zeeshan> just pay for shipping
[19:20:20] <MrHindsight> lathe has been gathering dust for 3 years, was a cheapo since the wiring was messed up plus the gearbox had problems
[19:20:26] <zeeshan> lol
[19:20:27] <zeeshan> dude
[19:20:31] <zeeshan> i have all the quick change gear box
[19:20:33] <zeeshan> parts too
[19:20:35] <zeeshan> using none of it
[19:20:36] <MrHindsight> sheared pin from somebody jamming it under power
[19:20:38] <zeeshan> except the case
[19:21:39] <zeeshan> i only kept the stuff
[19:21:43] <zeeshan> cause i was thinking mayhbe one day
[19:21:45] <MrHindsight> heh, it's just an extra manual lathe for brakes mostly
[19:21:46] <zeeshan> i'll need to use the gears
[19:21:48] <zeeshan> to power somethine up!
[19:22:16] <MrHindsight> skateboard
[19:22:46] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/lathe/qcgb.jpg
[19:22:48] <zeeshan> those gears
[19:23:01] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/lathe/wiring2.jpg
[19:23:04] <zeeshan> thats the control stuff
[19:23:28] <jdh> nice gears. get rid of them.
[19:23:33] <zeeshan> jdh old pic
[19:23:35] <zeeshan> theyre gone
[19:23:41] <zeeshan> im only using the casing
[19:23:42] <zeeshan> lol
[19:23:45] <zeeshan> for weight!
[19:23:57] <MrHindsight> abstract art project
[19:24:08] <zeeshan> haha
[19:24:32] <MrHindsight> this thing is just too soft to cnc for me
[19:24:33] <zeeshan> how abhout
[19:24:35] <zeeshan> free energy project
[19:24:43] <zeeshan> =)
[19:24:46] <jdh> hmm. I have a bunch of lead. I could pour it in my castings for weight.
[19:24:49] * zeeshan trolls
[19:24:55] <jdh> lead seem slike it would dampen also
[19:25:03] <zeeshan> jdh make me ahammer?
[19:25:04] <zeeshan> ;[
[19:26:09] <zeeshan> i wanna wire the vfd power side today
[19:26:11] <zeeshan> but im so lazy
[19:26:12] <zeeshan> :{
[19:26:29] <zeeshan> i got lazy after i maield out my power supplies to cnc4pc
[19:26:42] <zeeshan> i guess i could finish off the spindle wiring
[19:26:46] <zeeshan> and make the index wheel
[19:26:57] <zeeshan> and setup the limit switches before the toroid supply come sback
