[00:22:01] <kwallace> Oops. I ran down to the shop. The lathe is a Zubal: http://www.wallacecompany.com/cnc_lathe/
[00:23:20] <andypugh> andypugh: This looks fun: http://www.renishaw.com/en/resolute-rotary-angle-absolute-encoder-options--10939 I guess it is a development of the single-track multi-head gray-code idea? http://en.wikipedia.org/wiki/Gray_code#Single-track_Gray_code
[00:24:00] <andypugh> No Zubal on Lathes.co.uk How odd.
[00:26:37] <andypugh> Looks decent enough. The problem with converting manual lathes seems to be the amount of space for the ballscrew. Have you considered designing a complete new top-slide with no compound, adequate leadscrew room, and an ATC?
[00:27:57] <andypugh> (Mounting the ballnut well above the dovetail creates more space, and you have the space, as you don't need the Compound)

[00:35:34] <kwallace> Yes, the X slide has been a real problem. One option has been to mount the screw on the backside of the carriage, but this will stick out the back quite a bit. There are a lot of parts I can't make on the HNC because the X slide is so high, so I'm trying what I can to keep the Zubal's slide low.

[01:00:56] <andypugh> kwallace: A rotating nut arrangement might help.
[01:04:27] <andypugh> kwallace: If you imagine a ballnut with the largest possible timing belt pulley round it in the position of that hexagonal plate, with the motor pointing into the picture and the ballscrew mounted rigidly where the feed dial currently is.

[01:10:24] <Jymmm> I *THINK* I found the issue with my car not stating.... a semi-corroded fuel pump connector. what coould I spray to clean it? It's in a reall tough/tight spot to get to
[01:10:46] <Jymmm> as in frame touching my chest sorta way
[01:11:21] <tjb1> Probably gonna need to take it off and cleane it
[01:11:29] <tjb1> Knife, wire brush...
[01:11:36] <Jymmm> can't, would have to drop fuel tank
[01:11:42] <cradek> chop chop, wire nut
[01:11:51] <Jymmm> it's a recessed "waterproof" connector
[01:12:03] <tjb1> Get droppin
[01:12:16] <Jymmm> multi conductor, that would expose it too much
[01:12:19] <cradek> yeah... and get a new fuel pump while it's dropped
[01:12:37] <cradek> car or pickup?
[01:12:41] <Jymmm> SUV
[01:12:46] <cradek> yuck
[01:12:58] <tjb1> I dont know of anything you can spray that would fix it
[01:13:03] <tjb1> Maybe a sand blaster lol
[01:13:07] <Jymmm> I can't drop the tank, dont have the tools, jakcs, etc to do it even if I wanted to
[01:13:17] <ReadError> hey guys
[01:13:19] <Jymmm> and it's full too
[01:13:20] <cradek> I helped my ex with a bronco fuel pump - we took a jigsaw and cut the floor out over the damn thing
[01:13:28] <ReadError> excited about my aluminum order
[01:13:34] <ReadError> should be here tomorrow
[01:13:35] <cradek> of course it's full. they don't fail empty...
[01:13:47] <ReadError> paid only 28$ for 72", and overnight shipping for 3.99
[01:13:54] <Jymmm> cradek: Heh, I wish there was an access door.
[01:14:04] <cradek> I'm 100% serious - just make one
[01:14:08] <tjb1> You can pull the backseat out of my car and un bolt a panel
[01:14:09] <tjb1> :)
[01:14:32] <Jymmm> contact cleaner?
[01:14:33] <cradek> in a pickup you can sometimes pull the whole bed off easier, but with an suv, jigsaw is the right approach
[01:14:54] <Jymmm> if I had a pickup, I'd pull the bed in an instant
[01:15:00] <cradek> how old is it?
[01:15:04] <kwallace> andypugh: The present acme screw is pretty small with very little clearance. I'm not sure I can push a thin ball screw the distance from the back to the front of the sldie, but I can mount it towards the back and have the floating end run into the present screw slot.
[01:15:17] <Jymmm> 2001, so it has ever electronic sensor you could imagine
[01:15:19] <cradek> and how sure are you? did you do a pressure test and see it's not pumping?
[01:15:32] <Jymmm> cradek: 0 psi at the fuel rail
[01:15:46] <cradek> bing bing
[01:15:49] <cradek> that's a pretty good test
[01:16:10] <cradek> but it works sometimes?
[01:16:14] -!- Alf__ has quit [Quit: ChatZilla 0.9.89 [Firefox 18.0/20121231071231]]
[01:17:03] <tjb1> My s10s fuel pump shut off sporadically then one day it died
[01:17:08] <andypugh> cradek: Our cars have a plastic patch held on with Velcro over the fuel pump :-)
[01:17:09] <cradek> yeah that's very normal
[01:17:10] <Jymmm> I got the FORD manuals, went throught the troubleshooting, has about to take 12V from the battery directly to the pump, spent 20m disconnecting the connector and I think it's corroded, I can't see for sure (my eyes)
[01:17:42] <cradek> oh you can get to it? if you mess with the connector at all and it still doesn't work, it's surely the pump
[01:17:48] <Jymmm> I see three gold pins, then 7 I *think* greenish tint pins
[01:18:04] <cradek> yeah the fuel level sender is in there too
[01:18:10] <Jymmm> Again, I just can't focus my eyes at this distance
[01:18:16] <cradek> replace that too while you have it out :-)
[01:18:21] <tjb1> Isnt there an acid that eats that off copper
[01:18:42] <kwallace> I don't think it's that hard to drop a fuel tank. One just needs plan it out in advance so there is a container and such on hand when needed.
[01:19:11] <Jymmm> Well, if the three pins are gold, and the other 4 are greenish, there has to be something I could clean/spray to clena it with
[01:19:27] <andypugh> I have an ancient bottle of contact cleaner. Works well, actually. No idea if you can still buy it. Brand was "Electrolube"
[01:19:35] <Jymmm> I'm going to grab a camera and go back under the car
[01:19:47] <Jymmm> andypugh: I have some 1-1-1, but it's not spray
[01:19:50] <cradek> Jymmm: yeah cameras can sometimes focus better at weird distances...
[01:19:58] <Jymmm> bbiab
[01:20:00] <cradek> I have deoxit, but I'm not sure it's that great
[01:20:19] <cradek> try a wire bottle brush or something?
[01:21:08] <cradek> ford has special clips on the fuel lines too - hard to remove even with the special tool
[01:21:44] <andypugh> kwallace: In my proposal the actual ballscrew can be the full width of the slot in the saddle. (and that has to be bigger than the current one, as that has a nut around it)
[01:22:22] <kwallace> Deoxit made the world of difference on my bench supply rotary switches.
[01:23:03] <andypugh> Then you can either mount the screw solidly where the handwheel currently is (which might make a full splash guard easier too)
[01:23:15] <cradek> kwallace: I guess it's done ok on my radios too
[01:23:17] <Jymmm> kwallace: where to get that?
[01:23:58] <ve7it> kwallace, have you had your washing motor spinning.... I have a similar unit with the drive... seems like a nice motor 16000rpm.. I am still wondering if I can hack the cpu in the controller
[01:24:12] <andypugh> Or mount the ballnut outboard of the back of the saddle, have the bearings where the handwheel currently is, and twirl the screw with a motor at the back that travels with the cross-slide
[01:24:19] <kwallace> I think I got mine at Digikey. It's not cheap.
[01:24:45] <cradek> I've had mine for 10? years - no idea what it cost
[01:24:46] <ReadError> does 6061 machine pretty nice?
[01:24:53] <cradek> ReadError: yes
[01:25:06] <ReadError> does it get gummy ?
[01:25:17] <cradek> sure, but not as bad as some aluminums
[01:25:57] <Jymmm> Hmmmm http://www.homedepot.com/buy/crc-2-26-5-oz-multi-purpose-lubricant-02004.html
[01:26:10] <cradek> use a big high helix cutter and flood coolant and you'll be fine as heavy as your machine can cut
[01:27:08] <andypugh> I killed 3 cutters (2.5mm carbide) cuting less than 2" of 2mm aluminium sheet yesterday, and then gave up and resorted to hand tools.
[01:27:24] <cradek> Jymmm: if it's really gunked up, mechanical cleaning is better than chemical cleaning
[01:27:27] <andypugh> I was making D-Sub cutouts.
[01:27:52] <cradek> andypugh: why such a small tool? you don't need sharp corners for that.
[01:28:18] <ReadError> these 3$ carbide endmills are working pretty good
[01:28:21] <Jymmm> cradek: Sure, but my nose is 8" from it; I had to become a human contosionist just to release the connector in the first place =)
[01:28:34] <ReadError> normally g10 is a bit killer
[01:28:53] <cradek> andypugh: (I've always wanted a punch for those...)
[01:28:54] <ReadError> plus i got a pretty nice case with them too
[01:28:57] <andypugh> cradek: 2.5mm isn't that small, and the program also makes the M3 mounting holes.
[01:29:03] <Jymmm> cradek: and of course my turit wanted to get into the act too
[01:29:04] <cradek> ah
[01:29:50] <kwallace> ve7it: Yes. I bought a high or rather higher frequency VFD for it. When I got it I realized it had 440 Volt input I had to hack a way to get 440 so I haven't run it much. Even at 16k it's very smooth and quiet, but I guess for a washing machine it needs to be.

[01:30:50] <cradek> Jymmm: do you have 1 or 2 fuel lines going to the pump?

[01:30:54] <ve7it> I was hoping to drive a high speed spindle made from a er16 stub collet
[01:31:00] <Jymmm> cradek: 3 =)
[01:31:09] <cradek> whuh?
[01:31:16] <Jymmm> exactly
[01:31:36] <kwallace> ve7it: The motor runs at 110 V so I also had to program the VFD for reduced output voltage.
[01:31:45] <Jymmm> cradek: the 3rd is some emissions thing I think
[01:32:24] <Jymmm> cradek: The manuals are over 5000 pages, so it takes some time figuring out what all of them are for
[01:32:30] <Jymmm> =)
[01:33:01] <andypugh> My job is fuel-pump control.
[01:33:19] <andypugh> We run them closed-loop now to save energy.
[01:33:50] -!- ve7it has quit [Remote host closed the connection]
[01:33:52] <andypugh> I have a PID controller to program to make sure that the lift-pump only runs as hard as it needs to.
[01:33:54] <cradek> in 2001 was his a bypass regulator?
[01:34:37] <andypugh> His is probably gasoline, which is nearly as much a mystery to me as diesel is to my American colleagues.
[01:34:44] <cradek> ha
[01:35:06] <andypugh> I just need to keep the HP pump happy (and lubricated)
[01:35:55] <andypugh> The main job of the lift-pump is actually to feed the bearings in the HP pump.
[01:35:59] <kwallace> ve7it: I don't think the motor bearings are good enough to drive the collet holder directly. I think one would need to replace the bearings with at least a pair of angular contact bearings or just belt drive a separate spindle.
[01:38:11] <andypugh> kwallace: You could consider replacing both end-castings with components better designed for the job, and with suitable bearings.
[01:38:44] <ReadError> is there any "homebrew" method of straightening a piece of aluminum?
[01:38:52] <ReadError> im worried this stuff is going to come bent
[01:39:04] <ReadError> well, not perfectly flat..
[01:39:11] <andypugh> It's not brain surgery :-) http://youtu.be/THNPmhBl-8I

[01:41:47] <Jymmm> andypugh: rocket Science!!!
[01:41:58] <andypugh> ReadError: I imagine you could do something with the garage doorway, bricks and a hydraulic jack.
[01:43:46] <kwallace> andypugh: ve7it: Yes, the present end castings don't have a good way to mount the motor. I wanted to use the motor for a clamp-on spindle for the Shizuoka to mill wood or circuit boards. The mounting has set me back a ways time wise.
[01:44:09] <Jymmm> FUCK! I still can't tell if that's corrosion or just a mix of silver and gold plated pins http://i50.tinypic.com/2ro44tu.jpg
[01:44:21] <kwallace> Gota go eat. bbl.
[01:46:02] <andypugh> Jymmm: They look rather eroded to me, they possibly ought to be the same length too.
[01:46:36] <Jymmm> andypugh: They are the same length, just bad photo
[01:47:20] <andypugh> The silver pins are not all the same length,
[01:47:42] <andypugh> Or the same shape
[01:48:35] <andypugh> I don't know what the soluton is, but that plug looks dead to me, and the socket is probably no better.

[01:49:29] <ReadError> andypugh: was thinking a few blocks of thick wood
[01:49:30] <ReadError> and clamps
[01:49:44] <ReadError> wasnt sure if that would be enough to get it pretty true or if it would bounce back
[01:52:32] -!- morfic has quit [Ping timeout: 245 seconds]
[01:52:34] <andypugh> Depends on span and force. A doorway makes a pretty rigid bridge frame.
[01:53:21] <andypugh> But the principle is exactly the same whenever you try to straighten something.
[01:53:46] <andypugh> You probably want to use Science.
[01:53:47] <ReadError> ive never heard of this doorway method
[01:55:58] <andypugh> You need to know where the high point is, and the two adjacent low points. You also need to measure how high it is. Then, with a jack or clamps and a dial-indiacator, you press it past yield, then relax, then try again, until the dial indicator reads the right value.
[01:56:48] <andypugh> My guess would be that your curve span will be larger than your press. Hence the idea of using a doorway and some blocks.

[15:41:09] <skunkworks> Gene45, did you get my reply?
[15:42:00] <Gene45> yes and no... I'm sure I have it in a log file but was not aware that you answered. Been doing fresh installs in sytem etc
[15:42:17] <skunkworks> we re-purposed these servos.. http://electronicsam.com/images/KandT/DSC_0242.JPG
[15:42:20] <Gene45> did you use the existing servos and powersupply
[15:42:53] <skunkworks> originally - the machine used hydraulic servos. We replaced them with large brushed dc

[15:45:20] <skunkworks> y axis hydraulic servo
[15:45:36] <awallin> JT-Shop: forum post - is there a driver for the ethernet based mesa card?
[15:45:47] <skunkworks> converted.. http://electronicsam.com/images/KandT/conversion/yaxis/yassembly.JPG
[15:46:01] <skunkworks> awallin, yes - but the bugs are being worked out....
[15:46:59] <skunkworks> xz and b originally shared 1 servo.. http://electronicsam.com/images/KandT/conversion/xaxis/start.JPG
[15:47:14] <awallin> skunkworks: previously the excuse for these was always that whenever the NIC chip on the pc-side changes strange things could happen... but maybe things are better now
[15:47:46] <Gene45> Im sure you see the beauty in it... but that thing is a pig :)
[15:47:58] <skunkworks> best from the 60's

[15:49:36] <skunkworks> thanks
[15:49:55] <skunkworks> awallin, I don't know the specifics...

[18:25:54] <Guest78964> i should have known..
[18:25:59] <Guest78964> anyhow

[18:26:06] <Guest78964> this nicks just as good :)
[18:26:40] <Guest78964> i have done some latency test runs a few hours ago
[18:27:13] <IchGuckLive> and
[18:27:16] <Guest78964> with 8.04 and 10.04 lts based linuxcnc iso installations
[18:27:35] <IchGuckLive> Realtime or standard kernel
[18:27:42] <Guest78964> well, 10.04 is seeing some regression
[18:27:44] <Guest78964> rtai
[18:28:07] <mrsun> hmm china hss vs "quality" hss ?
[18:28:09] <IchGuckLive> what is the 25ms
[18:28:20] <Guest78964> mhm, nope
[18:29:05] <IchGuckLive> mrsun: china price verses standard price O.O
[18:29:18] <mrsun> IchGuckLive, but the quality of it? :)
[18:29:22] <mrsun> is the only diff the price? :)
[18:29:27] <Guest78964> it was more like 5,8 and on 10.04 15,20 (
[18:30:19] <IchGuckLive> mrsun: Hss is defined at iso standard so it shoudt need your meanings
[18:30:53] <IchGuckLive> mrsun: on CO8 i woudt be nervice if it is not only collored

[18:36:09] <skunkworks> You will see different latencys between 8.04 and 10.04...
[18:36:16] <skunkworks> they are different kernels.

[19:28:00] <kwallace> What are common methods for touching off a lathe tool with no Z face, such as a threading tool? I would tend to just eyeball the point because thread Z position isn't usually critical, but I'm wondering if there are other situations where Z position is critical and the tool has no convenient Z face. What do the fancy lathes do with threading tools and automated touch off?
[19:30:42] <kwallace> I can imagine a touch off probe with two pins aligned to the Z axis and touch off the right and left tool angle then divide the distance.
[19:34:10] <archivist> the tool has a specified radius so you can know its length, but I tend to turn a thread, measure,edit, rinse repeat till fits/near enough
[19:34:20] <kwallace> Or, rather one pin and touch off each side of the pin.
[19:34:48] <archivist> but that problem exists for gear cutting too
[19:35:35] <archivist> some tools like hobs have a reference diameter written on them
[19:36:33] <kwallace> Yes, the X bit is easy. Just cut and measure a diameter, or use a gauge pin on a known diameter.
[19:36:41] <Connor> Okay, so, without some smart a$$ answer as like "as much as you can afford" etc etc.. I'm looking at getting a surface plate. I'm trying to figure out what to get. I don't want anything huge, I think a 9x12 or 12x18 would be fine. But, what about the thickness and grade.. and what's the deal with T looking shape of some of them..
[19:37:37] <Connor> Looks, like they're AA, A, B.. Don't see a C on Shars.com..
[19:38:30] -!- halo_cast has quit [Ping timeout: 264 seconds]
[19:39:47] <jdh> I'd say try to afford somethign as big as you might need.
[19:39:53] <devilindisguise> IchGuckLive: i am using 2.5.1 axis gui and i dont see svg and dxf when trying to open a file. is it me?
[19:40:36] <cradek> Connor: the T makes them easy to pick up and move.
[19:41:09] <cradek> Connor: a 12x18 is barely light enough to ship via UPS. any bigger would be a much bigger pain to get to you.
[19:41:10] <Connor> jdh: Well. I'm more looking at the space in my tiny shop for the size...
[19:41:47] <cradek> take a piece of board 12x18 and glue felt to it. put that face down on the plate when you're not using it, and you have a nice little flat surface to pile other things on
[19:41:50] <Connor> Looks like the A's all have the T shape.. B grade is just flate.
[19:42:02] -!- maximilian_h [maximilian_h!~bonsai@] has joined #linuxcnc
[19:42:14] <archivist> or a bit of polished granite for a tile, they seem reasonably flat for small work, I do wonder how flat they are
[19:43:45] <archivist> I looked at the reflection of the shop roof in one, bought it to try, its under these bits http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_11_07_Drive_gear/IMG_1400.JPG
[19:45:56] <kwallace> What will the plate be used for? Height gauge or test workpiece flatness?
[19:46:50] <Connor> Both Probably.
[19:47:40] <Connor> I mean honestly.. I don't have a use for right at this time.. I just know, that they're good to have in a shop. ;)
[19:48:21] <archivist> I use my grade A for testing levels
[19:48:58] <devilindisguise> i use linuxcnc-dev checked out via git on 26t of december and ./configure --prefix=/usr --enable-simulator, i havent seen a option for enabling dxf or svg.
[19:50:11] <kwallace> I have a granite plate, but I find I use my table saw top as a flat surface more often because the plate holds all the clutter that falls off my bench.
[19:51:03] <cradek> Connor: an old typewriter table makes the very best surface plate holder for one that size. it has wheels, and can lock in place.
[19:51:28] <cradek> and an 80lb 12x18 plate is about the weight of a good typewriter, haha

[19:52:33] <ds3> are good typewriters flat? :D
[19:52:43] <cradek> haha nope
[19:53:01] <Connor> I have a few things that might work to hold my surface plate. I made a cart to hold my tools out of a hanging file folder cart. Basicly it's a mini-shelf on wheels. I have a printer stand that's about the same size.. and then of course, my nice 7' x 39" Stainless Steel Elevator door as a bench. :)
[19:53:49] <kwallace> cradek: How do you touch off the sides of a lathe threading tool?
[19:53:51] <archivist> the mill table can double as a plate for some lower grade work
[19:54:11] <cradek> there's a million of them on ebay: http://www.ebay.com/itm/170969492560
[19:54:24] <cradek> these are absolutely perfect for the job
[19:54:42] <devilindisguise> bye. have a nice time
[19:54:42] <cradek> The top area is 18" x 15". When the side are extended it measures 36" wide.

[19:55:23] <archivist> except if testing levels, wheels too soft
[19:55:51] <Connor> Hmm.. Grizzly has Grade B 12x18x3 with ledge for 43.95
[19:56:06] <Connor> $79.00 to ship ROFL
[19:56:20] <kwallace> For the cost of shipping , I'd just glue up a 2x4 table.
[19:56:46] <archivist> get a second hand one locally
[19:56:50] <cradek> heh yeah, you'd want to find one locally
[19:57:15] <cradek> not hard if you know your local junk sources
[19:57:18] <Connor> I'm checking Shaars.
[19:57:45] <Connor> $48.11 + 47.50 for a grade A 12x18x3
[19:57:46] <archivist> mine are ex mill surplus
[19:58:27] <cradek> check enco. they have free ups shipping very frequently.
[19:58:58] <cradek> yeah free ups ground for $49+ orders through january
[19:59:13] <kwallace> 12 x 18 sounds like you could just fit a height gauge and a small work piece. I'd go bigger unless one has a particular application that doesn't need the extra space.
[20:00:56] <Connor> Place right down the road that sells Granite... I wonder if they do surface plates...
[20:01:09] <Connor> I think it's mostly for counter tops etc...
[20:01:20] <kwallace> I would also tend to go the the local counter top place an get enough stone to make two plates and use one on the other with grit to flatten them.
[20:02:00] <archivist> 3 to make a flat 2 gets a curve
[20:02:21] <Connor> and how much work does that take?
[20:02:28] <archivist> some
[20:02:58] <archivist> an apprentice learning to scrape has to do it
[20:03:26] <kwallace> True, but If one swaps top and bottom enough they could get pretty darn flat.
[20:04:10] <Connor> kwallace: I'm mostly doing small stuff anyway.. Robot parts... etc..
[20:04:21] <Connor> don't need anything supper large..
[20:05:26] <Connor> besides, like I said, I have room size constraints.. room is only 11x7.. and my work bench, mill, tool box, 6" sander, and vacuum box all are in it..
[20:07:30] <Connor> Enco too $$$ on the plates.. way more than Shars for the AA. $113.54 before shipping vs 47.95

[20:20:04] <frysteev> i like the idea of emc for use as the logic and motion control, but the project im proposing, the client wants to use mach as the front end, so all his interfaces are the same

[20:27:49] <skunkworks> Hi
[20:27:51] <kwallace> Custom tabs in AXIS could go a long way to getting the buttons and scripts one likes from Mach.
[20:27:55] <jdh> but, I'm not going to pay for a win + mach license when this is free and arguably better
[20:29:23] <kwallace> Customers pay for perception and not performance.
[20:30:34] <jdh> customers are different.

[20:31:05] <jdh> you should give them what they want, unless you can tactfully convince them of the error of their perceived wants.
[20:31:37] <Jymmm> Interesting http://www.youtube.com/watch?v=8EErSvJOyz4
[20:32:14] <frysteev> i just kind it very difficult to make tabs and such in emc, unless im doing it wrong
[20:32:54] <Jymmm> You should read "Lean Startup"
[20:34:51] <frysteev> i spend a few days reading the emc/mach debate until my brain melted
[20:35:23] <jdh> or no.
[20:36:40] <frysteev> actually i get the win/lunux thing, my head is trying to tackle the whore external motion controller
[20:36:48] <frysteev> er whole
[20:37:23] <jdh> the win/linux thing allows linux to do all the things external controllers do
[20:38:20] <frysteev> i get that,
[20:39:20] <skunkworks> so - if a realtime thing is added to linuxcnc - it is available to all interface devices. Like rigid tapping - hell you could rigid tap with the printer port hardware. WIth external motion devices - you are stuck with what is implimented within it.

[20:51:16] <frysteev> im curious, are people just running the ribbon cable from the computer, or using a scsi type connector on the chasis
[20:51:47] <skunkworks> JT-Shop has a neat tutorial on creating your own gui.. You will have to play with python...

[21:05:48] <frysteev> the 5125 only breaks out to a single card tho right?

[21:06:35] <frysteev> or i see

[21:10:16] <andypugh> You can connect one smart-serial device to the header on the 7i76, but there is the option to use the 7i74 and connect 8 of them to each port on the 5i25

[21:13:34] <skunkworks> Plust the 24 block opto22 boards hook right up to the masa 50 pin connectors
[21:13:38] <cradek> the best feature of opto22 is the LEDs and room for writing in pencil next to each one what it means
[21:13:38] <frysteev> and a 7137 equivalent in that series for general i/o?

[21:16:36] <frysteev> the 7164 will plug into the 5125 or 7177?
[21:16:39] <andypugh> 7i74 + 8 x 7i64 is 384 IO lines, would that be enough?
[21:16:40] <frysteev> Jymmm: lol
[21:17:05] <Jymmm> frysteev: Elepahnt "tons of" FIFO I/O
[21:17:17] <frysteev> 2 7161 should be enough
[21:17:36] <Jymmm> frysteev: No, you said TONS, you GET tons!
[21:17:37] <frysteev> im hoping i can get ity down to one 7164
[21:17:41] <frysteev> er 7164
[21:17:43] <andypugh> frysteev: One 7i64 into the 7i77, and/or as many as you need into a 7i74 on the second header of the 5i25. (the 7i77 connection is just a passthrough, actually)
[21:18:18] <frysteev> cool i like that, cuz then i get get my machine moving before working about all the other i/o
[21:18:35] <andypugh> If you already have opto22 racks then the 7i69 is much chaper than the 7i64.
[21:19:55] <andypugh> 7i64 is all isolated and high voltage/current (well, 50V, 2.5A) but it's also expensive compared to the others.
[21:20:16] <frysteev> i think i will splurge on the 7164,
[21:20:36] <andypugh> I think Pete said that voided the warranty
[21:20:50] <skunkworks> no - that was drrooling...
[21:20:57] <skunkworks> drooling
[21:21:09] <skunkworks> he said nothing about splurging
[21:21:32] <frysteev> im hoping to not need as much dedicated i/o and move some stuff over to serial, not real time stuff
[21:21:53] <andypugh> Is there any reason to prefer angular contacr bearigns to taper rollers for holding a ballscrew?
[21:22:10] <skunkworks> frysteev, what is the project?
[21:22:22] <frysteev> 4x8 laser cutter
[21:22:25] <skunkworks> andypugh, Friction probably...
[21:22:41] <skunkworks> (taper rollers will have more) IMHO
[21:22:49] <kwallace> I think rollers have a much lower RPM limit.
[21:22:55] <skunkworks> That too
[21:23:26] <frysteev> skunkworks: all off the modules inside the machine have serial, but wasnt implentment
[21:23:47] <skunkworks> huh
[21:24:04] <skunkworks> is it stricly cutting? (not rastering?)
[21:24:46] <skunkworks> But I think for andys ball screw - the bearing rpm will be fine.

[22:12:33] <Connor> kwallace: skunkworks: Reply from the says it's heat dispassion. I'm assuming it's because of the breaking resistor more than anything. Mine is on the opposite side than what their manual shows.. so mounting it that way would be fine.
[22:15:15] <kwallace> I think the resistor might set the feedback voltage for speed control. If so, it might be On all the time. If it's an issue, I'd mount a fan somewhere.
[22:15:57] <Connor> No. The one on the side is HUGE wire wrapped based resistor. It's for dynamic breaking..
[22:16:54] <Connor> The only other is the current sense resistor.. and it plugs in on the main board.

[22:20:26] <Connor> Those of you who are up on bearings. What's the difference with placing AC bearings back to back vs face to face ? I would think it wouldn't matter.. but, the contention is back to back..
[22:23:29] <ReadError> im reading marvel mystery oil might be good
[22:23:37] <ReadError> but wd-40 seems promising

[22:27:55] <kwallace> I think the fluid provides cooling and/or lubrication. My guess is that one could take a cut, then decide if one or both are needed.

[22:31:19] <Valen> Connor: look at the distance between the bearing surfaces in each configuration
[22:31:27] <Valen> one will be stiffer
[22:32:09] <Connor> I know which way is which.. I'm just asking why place back to back vs face to face.

[22:55:59] <Valen> got a customer bitching that it took 3 hours to fix a narky firewall issue that started an hour outside business hours, anybody have any info on standard resolution times for IT services?
[22:57:13] <kwallace> Figure 65 shows two angular bearings. I think the import bit is the effective spread, but I don't really know. The thing with matched pairs is that they are selected to have a certain preload when the faces are touching. I'm not sure if the preload is the same F2F or B2B.
[23:00:11] <tjb1> JT-Shop: You can fit mine
[23:00:16] <tjb1> fix
[23:00:31] <JT-Shop> I'll put you on the list...
[23:00:41] <tjb1> Ah...
[23:02:35] <ReadError> Valen: if its actually down
[23:02:40] <ReadError> our SLA is 1 hour
[23:02:46] <ReadError> if its just a change they need made, 4hr
[23:02:49] <Valen> to respond or to fix?
[23:03:04] <ReadError> either or
[23:03:08] <ReadError> depending on the issue
[23:03:16] <ReadError> we just need to keep them in the loop frequently
[23:03:30] <ReadError> plus it depends if they broke it or not ;)

[23:05:48] <ReadError> frysteev: i have an atom d525
[23:05:52] <ReadError> it was fairly cheap and works well
[23:05:57] <kwallace> I looked at the latency of a few servers, some with Xeons and they where no better than old Celeron PC's.
[23:07:06] <kwallace> I think the Celerons work well because they are so basic.
[23:07:14] <frysteev> im wondering down sides of using a server, if i already have one,
[23:07:37] <frysteev> i like the idea of a hardware raid and dual power supplies
[23:08:13] <Valen> ReadError: its just a consumer wifi/modem with unexpected suckyness
[23:08:52] <skunkworks> frysteev: throw the livecd in it and test....

[23:08:58] <andypugh> kwallace: I don't have that kind of money :-)
[23:09:45] <kwallace> I'm typing on a P4 server now. It has a random realtime error about five to twenty minutes apart. The video was a bear to get working.
[23:10:00] <Valen> the atoms seem to have the lowest latency of anything you can buy
[23:10:35] <Valen> I hold the record for the lowest published in the wiki page with a dual Xeon 3.06Ghz though ;->
[23:10:37] <frysteev> skunkworks: good call
[23:10:55] -!- chopper79 has quit [Quit: Leaving.]
[23:11:45] <kwallace> But it's still a bit of a gamble on which atom board will work. I'd test the PC's you have and go with the one that is good enough.

[23:15:03] <ReadError> so wd40 works pretty good for you?
[23:15:44] <skunkworks> it works pretty well - I have gone through gallons of it making some parts befor the flood coolant was set back up
[23:15:57] <skunkworks> kwallace: I have heard that also
[23:16:22] <skunkworks> tjb1: what is the issue with the gecko?
[23:16:36] <tjb1> Outputs turning on when power is removed from g540
[23:17:11] <skunkworks> interesting.
[23:17:56] <tjb1> Yes, they didnt catch it but I dont think they really tested for that
[23:18:08] <tjb1> the relay needs external power and only remove power from the g540, not the relay
[23:19:40] <t12> ok
[23:19:46] <t12> anyone up for some

[23:20:36] <ReadError> and the voltage spike is turning on the relay?
[23:21:07] <tjb1> I have no idea, you take power away from the G540. The relay activates

[23:43:54] <Valen> SSRs are generally pretty slow
[23:44:04] <Valen> IE they don't respond well to PWM
