[00:38:20] <pink_vampire> hi
[14:33:17] <enleth> https://upload.wikimedia.org/wikipedia/commons/d/d1/Francis_Runner_InWorkshop_300.jpg - that's one hell of a... lathe?
[14:35:50] <enleth> appears to be a Korean NILES 4-axis vertical lathe
[14:39:05] <FinboySlick> enleth: How long until some dude with a Honda Civic tries to use that as a turbo?
[14:50:15] <djdelorie> If it's a Honda Civic aircraft carrier, perhaps
[14:52:35] <SpeedEvil> Is that an 8-jaw?
[15:03:54] <Bushman> http://imgur.com/rbJign6
[15:06:19] <Tom_itx> nice clean board
[15:08:24] <malcom2073> Hmm. I have a 1/4" thick piece of angle aluminum. It's 2" by 2". How far do you think it can overhang my vise, and not bend when I try to mill holes on it?
[15:09:39] <Tom_itx> 6' but i could be wrong
[15:09:51] <Simonous> lol
[15:09:54] <malcom2073> Hah
[15:09:55] <Simonous> 6' eh?!
[15:09:58] <Tom_itx> support it on both ends
[15:10:05] <malcom2073> I only have once vise
[15:10:11] <Tom_itx> vice clamp and support under the other end
[15:10:22] <_methods> makeshift jackstand
[15:10:25] <malcom2073> Heh
[15:10:26] <_methods> nuts and allthread
[15:10:28] <Simonous> if you are milling reasonably slowly you should have no trouble overhanging it 1"
[15:10:37] <Tom_itx> would that make it all jacked up?
[15:10:42] <_methods> hehe
[15:11:01] <malcom2073> Simonous: I've milled things like that overhanged 4-5" without issue, but it's 24" long and my vise is only 6" for this next piece :/
[15:11:02] <Simonous> Bushman: very nice looking board
[15:11:27] <Simonous> malcom2073: *nods*
[15:11:28] <malcom2073> So that's 9"
[15:11:51] <Simonous> malcom2073: that makes sense but I missed something. I thouhgt you said it was 1/4" x 2" x 2"
[15:12:02] <Simonous> I missed the angle part
[15:12:10] <malcom2073> Ah heh
[15:12:15] <malcom2073> Yeah it's angle
[15:58:20] <Bushman> Tom_itx, Simonous: thanks. Glad you guys like it. ;]
[16:07:54] <yasnak> never had issues with titanium before
[16:08:11] <yasnak> then I notice the high pressure pump is turned all the way up, full bore barely pushing out 400psi
[16:08:33] <yasnak> money in money out
[16:21:19] <zeeshan|2> malcom2073: do it!
[16:23:54] <JT-JA13> now I need to guess which opto is out on the C1 card from cnc4pc
[16:25:01] <zeeshan|2> JT-JA13: how dare you use non mesa
[16:25:04] <zeeshan|2> when youre a mesa seller!
[16:25:07] <zeeshan|2> :)
[16:25:23] <JT-JA13> leftover from early days lol
[16:25:38] <zeeshan|2> haha
[16:25:53] <JT-JA13> I have a C1 and a C1G
[16:25:59] <zeeshan|2> they're pretty decent
[16:26:01] <zeeshan|2> stepper machine?
[16:27:38] <JT-Shop> trying to cobble up a gantry machine and using the C1 until I can get my hands on some 7i78 cards
[16:28:42] <zeeshan|2> gantry machine?
[16:28:44] <zeeshan|2> plasma cutter?
[16:29:18] <JT-Shop> gantry yes, maybe engraver or something more to learn/test JA
[16:30:18] <zeeshan|2> ah cool
[16:32:47] <Deejay> gn8
[17:00:52] <JT-Shop> I figured out which opto was bad, the one between my eyes and brain
[17:03:14] <BitEvil> :)
[17:06:57] <JT-Shop> yea movement on JA
[17:10:50] <malcom2073> zeeshan|2: I did it
[17:10:53] <malcom2073> zeeshan|2: Even got videos of it
[17:26:11] <Tom_itx> gonna keep em to yourself?
[17:26:55] <malcom2073> Psh, they're gonna take a while to upload heh
[17:27:35] <Magnifikus> anyone aware of edgefinders for small machines? not that 100mm long ones with 20mm shaft
[17:27:48] <Magnifikus> or the mechanic ones that wont survive in min 5k rpm spindles
[17:28:28] <Duc> thought the standard starret edge finder was small
[17:28:53] <Tom_itx> that's what i use on my sherline
[17:30:11] <Magnifikus> that kind of finders dont like 5k rpm cause they are rated 500-800 on the pages or im wrong? :)
[17:31:04] <malcom2073> Can't spin your mini mill down that far?
[17:31:48] <Tom_itx> yes that's true
[17:32:01] <Tom_itx> none of them work at high rpm
[17:37:30] <malcom2073> https://scontent-iad3-1.xx.fbcdn.net/t31.0-8/13087016_1270937056254006_170480572230344895_o.jpg
[17:37:33] <malcom2073> A picture finished uploading heh
[17:38:52] <Magnifikus> will get a new spindle soon with fu, that should go down i hope
[17:41:33] <XXCoder> Magnifikus: well you can always use gage rod
[17:41:40] <XXCoder> use paper and move slowly in
[17:41:45] <XXCoder> till paper cant move
[17:41:56] <XXCoder> then go up and move 1/2 gage rod dia in
[17:42:34] <Magnifikus> true :)
[17:43:10] <XXCoder> I think that will be my plan, just need single good precision gage rod
[17:43:23] <XXCoder> with number easy to memorize lol
[17:43:37] <Magnifikus> you can create a macro for that :D
[17:44:39] <Magnifikus> http://www.sorotec.de/shop/Fraesmotoren-neu/hf-spindeln-manuell/Mechatron-Spindeln/Hochfrequenzspindeln-392/Komplettsystem-HF-Motorspindel-8022-luftgek-hlt-2-2kW-4818.html
[17:44:47] <Magnifikus> sorry for german link, but any objections to that?
[17:45:08] <Magnifikus> its for an 500x500 isel portal mill
[17:45:27] <Magnifikus> to get rid of spindles for the next years or longer
[17:45:44] <XXCoder> Magnifikus: what is better is gage sheet, with known size. then you can comp for its thickness
[17:45:53] <XXCoder> though it depends on your orecision needs
[17:46:22] <Magnifikus> right now i approach until i see a mark
[17:46:54] <Magnifikus> and for high z precision i face a fixture
[17:47:05] <Magnifikus> dunno just casings and parts for rf stuff
[17:47:37] <XXCoder> one of interesting ideas, if stock is conductive, is attach wire to gage rod and part itself
[17:47:41] <Magnifikus> so no ultimate acuracy
[17:47:46] <XXCoder> and testing resistance
[17:47:57] <XXCoder> when it goes to zero its touching
[17:48:04] <Magnifikus> yeah that works fine if you can isolate
[17:48:32] <Magnifikus> like a plate with known thickness and plastic backside
[17:48:56] <XXCoder> hm yeah thats flaw, I'm assuming gage rod is not connected to stock which isnt nesscarly the case
[17:49:15] <Magnifikus> spindle should be earthed
[17:49:17] <XXCoder> (long way around though machine)
[17:49:20] <Magnifikus> so is all of the machine
[17:49:41] <Magnifikus> you should see a difference in resitance due to shorter path
[17:49:53] <Magnifikus> but i doubt its very good for all day use
[17:50:05] <Magnifikus> + wont work with pvc etc
[17:50:30] <Magnifikus> and bad contact day will end in broken gage rod
[17:50:51] <XXCoder> yeah I'd just do paper
[17:50:51] <malcom2073> https://scontent-iad3-1.xx.fbcdn.net/hphotos-xla1/t31.0-8/13072829_1270940699586975_893040742028439780_o.jpg and
https://scontent-iad3-1.xx.fbcdn.net/hphotos-xpt1/t31.0-8/13072744_1270940726253639_511606884819238406_o.jpg
[17:51:15] <XXCoder> nice
[17:52:00] <Magnifikus> btw if an vfc offers 0-32khz controll for speed, its the thing of choice right?
[17:52:13] <Magnifikus> like that far more than 0-10v
[17:53:21] <XXCoder> good question, not expert on building and design lol
[17:54:52] <Magnifikus> me neither
[17:55:41] <Magnifikus> but frequency is quite "digital" oposed to analog values
[17:55:50] <Magnifikus> and im missing a dac so its much easier
[18:02:53] * JT-JA13 is building the latest JA13 deb
[18:07:13] <malcom2073> Hmm
[18:10:10] <malcom2073> Tom_itx:
https://www.youtube.com/watch?v=Easgs1SyoXs
[18:10:11] <malcom2073> It's processingheh
[18:12:16] <Bushman> dude, you could have waited till the video got processed.
[18:13:32] <malcom2073> Nah, need those pre-processing views
[18:13:40] <jdh> bushman: what did you do that board on?
[18:14:23] <Bushman> jdh: home made rig, run by LinuxCNC. wanna see some pics?
[18:14:30] <jdh> sure.
[18:14:44] <jdh> was that a small endmill or engraving bit?
[18:14:47] <jdh> looks kinda flattish
[18:14:51] <Bushman> V
[18:14:59] <Bushman> with flat tip
[18:15:32] <Bushman> when i bought it it was 60° 0.1mm...
[18:15:39] <Bushman> but now it's more of a 0.35mm lol
[18:15:41] <Bushman> XD
[18:15:57] <Bushman> (yes, i broke the tool the first time i tried to use it)
[18:16:17] <malcom2073> Heh nice
[18:16:19] <malcom2073> Bound to happen :)
[18:16:44] <Bushman> now, that i've improved my tool-chain, i no longer have such a big risk of digging into the laminate to deep
[18:17:49] <Bushman> it seems i've never actually to a proper picture of the current state of my setup :D
[18:18:04] <Bushman> it's so ghetto, you gonna like it! :D
[18:18:05] <malcom2073> Heh, go take a picture!
[18:18:10] <Bushman> brb, gonna snap one
[18:23:32] <Bushman> http://i.imgur.com/XL6aZaz.jpg
[18:23:48] <Bushman> old imgur was rebeling
[18:23:49] <Bushman> :D
[18:24:25] <malcom2073> Nice!
[18:25:09] <malcom2073> What's the table run on, more supported rail?
[18:25:47] <Bushman> yea, same rails in XYZ
[18:25:57] <malcom2073> Cool
[18:25:58] <Bushman> vacuum table added
[18:26:10] <malcom2073> Ohhh is that what the PVC pipe is?
[18:26:19] <Bushman> and now i'm working on this puppy:
[18:26:20] <Bushman> http://i.imgur.com/jho3sAN.jpg
[18:26:35] <Bushman> yea, that's the suction port
[18:26:36] <Bushman> :P
[18:26:36] <malcom2073> Oooo, 4th axis?
[18:26:55] <Bushman> yup
[18:27:12] <Bushman> i've also added a ghetto 3d printin head :D
[18:27:42] <Bushman> http://i.imgur.com/cVpxJnf.jpg
[18:28:06] <malcom2073> That's ghetto as hell, it work good?
[18:28:22] <Bushman> held by two flat insetrs to fit the same mount as kress
[18:28:28] <Bushman> sure! i have prints!
[18:28:31] <Bushman> http://i.imgur.com/fFr8Jwt.jpg
[18:28:44] <Bushman> http://i.imgur.com/CZCepA7.jpg
[18:28:57] <malcom2073> Nice, pretty smooth
[18:29:03] <Bushman> http://i.imgur.com/UmQ2e0L.jpg
[18:29:11] <Bushman> http://i.imgur.com/ytC1fOR.jpg
[18:29:26] <jdh> you print with linuxcnc also?
[18:29:46] <Bushman> sure
[18:29:53] <andypugh> I am amazed that I don’t have a 3D printer
[18:30:02] <jdh> the extruder is another axis?
[18:30:12] <malcom2073> The plastic has the characteristics of a linuxcnc print heh
[18:30:24] <jdh> I'd get one, if I had a working cnc lathe and a laser cutter
[18:30:26] <Bushman> i'm thinking about adding temperature controll into my setup, so i can set it in slicer
[18:30:39] <Bushman> jdh: 4'th
[18:30:49] <Bushman> i swap them out with rotary chuck
[18:31:02] <andypugh> jdh: It is possible to use “velocity extrusion” where the extruder rate is slaved to the axis motion.
[18:31:04] <jdh> how do you do the feed?
[18:31:10] <jdh> oh, like that
[18:31:33] <malcom2073> andypugh: velocity mode gets *much* better results heh
[18:31:34] <jdh> is there a comp for that?
[18:31:43] <andypugh> Though it just occurred to me that slaving axis motion to extrusion rate might be even better.
[18:31:51] <jdh> or is it just a kins?
[18:32:05] <malcom2073> jdh: iirc, it's some hal trickery
[18:32:36] <Bushman> i don't know about this stuff. i just configured my A as rotary and it works out of the box
[18:32:42] <andypugh> http://blog.machinekit.io/2014/05/velocity-driven-extrusion.html
[18:32:55] <Bushman> all i had to do was to tune the lenght/filament feed conversion ratio
[18:33:01] <malcom2073> Yeah my printer uses the A axis as the extruder too, and the slicer I use outputs A commands heh
[18:33:33] <andypugh> I wrote my own slicer. But I don’t have a printer :-)
[18:33:55] <malcom2073> andypugh: Build yourself one :-P
[18:34:14] <andypugh> https://www.youtube.com/watch?v=hefY46fyVvU
[18:34:37] <andypugh> I should port my slicer to Fusion360 and Take Over The World!
[18:34:48] <Bushman> why would anyone spend time writing slicer if he has no printer?! :D
[18:34:54] <malcom2073> andypugh: You should
[18:35:40] <Tom_itx> solidworks has a 3d print option
[18:35:42] <andypugh> Because a friend built a high-resolution DLP for small parts and hated the facets inherent to STL.
[18:36:15] <andypugh> So my slicer goes straight to svg with curves defined as curves.
[18:37:24] <malcom2073> andypugh: Be good for those layered laser cut thingies
[18:37:38] <malcom2073> Where you can make objects out of laser cut balsa or cardboard flats glued together
[18:38:05] <Bushman> what would you guys sugest as a means of controlling the temperature with linuxCNC?
[18:38:10] <Bushman> or at least setting it?
[18:38:12] <andypugh> Some Indian guy found the slicer and asked me for it to make books with shapes inside.
[18:38:17] <malcom2073> Bushman: I do PWM out to a Solid state relay
[18:38:24] <malcom2073> And run temp into an analog input, and let a PID control it
[18:38:47] <Bushman> i don't have analog inputs (yet?)
[18:38:54] <Bushman> i use LPT for my rig :P
[18:39:00] <malcom2073> Heh
[18:39:06] <malcom2073> Could get a temp controller just with an on/off?
[18:39:56] <Bushman> well, i was thinking about some AVR (like i have now) which is connected somehow to linuxCNC and "reads" the set temp from something
[18:40:06] <Bushman> serial maybe? USB?
[18:40:21] <malcom2073> That would work. You can call a script from HAL to have it read in an analog input (over serial)
[18:40:27] <Bushman> since it's not time-critical, it could do prety much anything, right?
[18:40:31] <malcom2073> Yeah
[18:40:44] <Bushman> yea
[18:41:11] <andypugh> Anaogue input is old-fashioned:
https://github.com/LinuxCNC/linuxcnc/pull/55
[18:41:24] <Bushman> so i'll have to learn some more about HAL in general and maybe write some plugin with GUI and stuff like that, and comunicate with my AVR over USB serial
[18:41:36] <malcom2073> Nice andypugh
[18:41:42] <andypugh> Bushman: That comp would work with the parport
[18:42:18] <jdh> isn't there an existing analog/avr/usb/hal thing?
[18:42:56] <Bushman> oh, that would be sweet
[18:43:10] <Bushman> i'd just have to implement the serial protocol and that's all :D
[18:43:49] <Bushman> heh, we'll see when i'll get the print head back on my rig :P
[18:44:01] <andypugh> Bushman: No, you just need to buy an MAX31855 and use that comp
[18:44:08] <Bushman> i guess the first thing i'll print will be a working extruder ;>
[18:44:26] <jdh> that would be less tacky than using an avr + usb
[18:44:39] <andypugh> They do cost $5, but then you have absolutely accurate temperature into HAL digitally
[18:45:07] <Bushman> andypugh: it's for thermocouple. my head has thermistor lol.
[18:45:11] <Bushman> i'll look into it
[18:45:30] <andypugh> Thermocouples are cheap, and more accurate
[18:46:29] <Tom_itx> PT1000
[18:46:42] <Bushman> hmm...
[18:46:43] <andypugh> In fact, you can spot-weld two bits of thermocouple wire to your extruder and get a really good thermal contact. The “magic” of a thermocouple is in the wire, not the junction.
[18:46:45] <Bushman> 3 pins...
[18:46:56] <Bushman> um... i'm not sure i have that many free :P
[18:47:13] <Bushman> one input and two outputs, right?
[18:47:24] <andypugh> Yes
[18:47:29] <Bushman> miso mosi and clock?
[18:47:46] <andypugh> Clock, select and data
[18:47:49] <malcom2073> Time for a PCI parallel card?
[18:48:29] <Bushman> malcom2073: that's not ghetto enough~!
[18:48:30] <Bushman> :D
[18:48:37] <andypugh> It might be possible to do something clever to turn on select with the clock in external (simple) logic
[18:48:37] <malcom2073> Bushman: Fine, USB to Parallel card :-P
[18:48:38] <Bushman> malcom2073: have you seen my extruder? lol
[18:49:40] <Bushman> andypugh: um... select?
[18:49:49] <Frank__14> heeyyy sorry to interrupt quick question, do u know some kind of easy recipe for epoxy grout for jointing steel and then tightening bolts? i cant remember the known brand that made it, but i dont live in the us. Thanks!
[18:50:24] <andypugh> I appreciate the concept of cheap and barely adequate. It’s a fun game. But I also like doing the best job I can. Sometimes you can be happier with your project if you just spend a bit of money.
[18:51:05] <Bushman> andypugh: i'd be happy to have the money i could spend.
[18:51:16] <andypugh> Bushman: I was making up the names, but with SPI there is the data in, the clock, and the “Oi! You, it’s your turn” line
[18:51:31] <Bushman> but since this is all hobby stuff to me, i can't really throw money at it ATM :(
[18:52:07] <andypugh> Bushman: My sympathies. I throw all my spare cash at my hobbies, because that is what spare cash is for.
[18:52:30] <andypugh> Frank__14: Machine mounting?
[18:52:36] <Frank__14> yes!
[18:52:37] <Bushman> andypugh: well, i'm not an SPI specialist but i was told it needs MISO, MOSI and clock to operate
[18:53:01] <Bushman> master input slave output, master output slave input, and clock
[18:53:07] <Frank__14> i send the hole thing to machine, but it wasnt a nice job
[18:53:17] <Bushman> so basically two way serial and clock to sync it up
[18:53:39] <Frank__14> look andy!, all the questions you answered made this :
http://imgur.com/HdkSmEJ
[18:53:41] <Frank__14> heh
[18:53:54] <andypugh> Bushman: The thermocouple chip is one-way. It might be possible to hard-wire the select high
[18:54:00] <Bushman> Frank__14: neat ;]
[18:54:10] <Frank__14> thankks
[18:54:12] <Bushman> andypugh: ah, makes sense
[18:54:20] <Bushman> even better
[18:54:27] <Bushman> only 2 pins needed
[18:54:29] <Bushman> :D
[18:54:45] <Frank__14> kind of bumped down right now, rails arent flat within each other, i have to epoxy grout or something
[18:54:59] <Bushman> oh
[18:55:01] <andypugh> Bushman:
http://uk.rs-online.com/web/p/instrumentation-amplifiers/7861017/ (data sheet link on the right)
[18:55:05] <Bushman> that sucks man
[18:55:44] <Frank__14> what are you running bushman?
[18:56:12] <andypugh> Frank__14: I would start with metal shims about every 5th bolt for a start
[18:56:18] <Bushman> my CNC? it's composite!
[18:56:37] <Bushman> wood with lots of screws!
[18:56:38] <Bushman> :D
[18:56:58] <Bushman> http://i.imgur.com/XL6aZaz.jpg
[18:57:34] <Bushman> Frank__14: how bad is the missaligment?
[18:57:55] <andypugh> Frank__14: Then when you are happy, build clay dams (or bolt on something neater) and run in the grout. I realise I have not got anywhere yet with what the grout should be
[18:58:09] <Frank__14> the rails are even on the horizontal plane, in every way you look at them, but they are angled in their own plane, i dont know if u can understand me, i can make a quick draw
[18:58:39] <Bushman> there are only 3 axis
[18:58:46] <Bushman> the one along them
[18:58:47] <malcom2073> Frank__14: That frame is looking pretty good!
[18:58:57] <Bushman> the one perpendicular horizontaly
[18:59:05] <Bushman> and the one perpendicular vertically
[18:59:39] <Tom_itx> _methods
[18:59:42] <Tom_itx> you around?
[18:59:57] <Frank__14> thaanks dude!
[19:00:12] <Bushman> Frank__14: if you look at the from the side, are the rails true?
[19:00:31] <Frank__14> if u mean the 2.4mts horizontally, yes,
[19:00:46] <Bushman> 2.4mts?
[19:00:50] <Frank__14> if u look at the (x?) axys (gantry) they are in different angles
[19:00:58] <Frank__14> 6feet
[19:01:05] <Frank__14> 8 sorry
[19:01:14] <Bushman> oh.. 2.4m ?
[19:01:30] <Frank__14> Yes :D
[19:01:36] <andypugh> Frank__14: You could drill and tap a pair of holes next to every 5th mounting bolt and put in an alignment screw from underneath (with a clearance hole in the bottom of the frame to adjust them by, for height and twist). That would make the rails perfect. Then you could lock that in with the grout.
[19:01:37] <Bushman> lol don't make up units lol
[19:02:24] <andypugh> Frank__14: Not in the US, but using feet, where ae you?
[19:02:55] <Frank__14> i quite suck using imperial units lol, but im from Argentina
[19:03:04] <Bushman> Frank__14: i think i need a drawing after all :P
[19:03:07] <Frank__14> thats the reason of my bad english
[19:03:40] <Bushman> as we look at it from the front, which is X?
[19:03:50] <Frank__14> yes, i was going to do that haha but i need to make a quick stop to buy some meat for tonight!
[19:03:54] <andypugh> Frank__14: You do a lot better than I would in Argentina.
[19:03:58] <Bushman> (the front being the side closer to us in the picture)
[19:04:03] <Frank__14> wrong me again, y axis gantry
[19:04:06] <Frank__14> i ment
[19:04:25] <Bushman> oh, so...
[19:04:47] <Bushman> long is X, short is Y and vertical will be Z (not present in the picture)
[19:04:54] <Frank__14> exactly
[19:04:54] <Bushman> ok
[19:05:07] <Bushman> now, are the X rails the problem?
[19:05:36] <andypugh> I have this crazy idea: Use the machine to machine alternate seats for the rails. Swap the rails to those. repeat. Would things get better or worse?
[19:05:46] <Frank__14> yes, when u look the y axis, the x have their own angle, but leveled to the horizontal plane
[19:06:07] <andypugh> As a complication, add software correction to the machining.
[19:06:57] <Frank__14> more than anything i try to fix this because when i tightened every hole, it kind of made a different noise when i pushed around the gantry
[19:07:12] <Bushman> ok, wait
[19:07:33] <Bushman> are the X rails parellel to each other?
[19:07:48] <Frank__14> i was thinking of just shiming the gantry steel
[19:08:12] <Frank__14> they should, as far as i could see with the dial indicator, they are
[19:08:15] <andypugh> Frank__14: I definitely think that a pair of screws pointing up at +Y and -Y of mounting bolts would be a useful addition.
[19:08:34] <andypugh> Is it clear what I mean?
[19:08:53] <Frank__14> you mean on the gantry "seats"?
[19:09:12] <andypugh> On the rails
[19:09:18] <andypugh> Well, under the rails
[19:09:25] <Frank__14> they are 23mm wide
[19:09:36] <Frank__14> even then?
[19:09:46] <andypugh> What size are the mounting bolts?
[19:09:50] <Frank__14> m6
[19:11:00] <Bushman> i'm still not sure what is the problem
[19:11:07] <Frank__14> i think the angle doesnt change along the x rail, i have to recheck that. thats why i thought with just epoxy under the gantry bolts would sufice ( so they do not torque the rails in the true angle
[19:11:09] <Frank__14> lol
[19:11:36] <Bushman> Frank__14: if they are parellel, are they rotated along the X?
[19:11:49] <Bushman> like one is nice and flat - and the other is crooked \
[19:11:50] <Bushman> ?
[19:12:04] <Frank__14> ill do a quick squecht in a min, let me go to the store really quick! haha Thanks guys, you really are awesome.
[19:12:05] <Frank__14> exactly
[19:12:14] <Frank__14> i dont think one is nice and flat
[19:12:15] <Frank__14> lol
[19:12:44] <Frank__14> maybe the sound i was hearing its just normal, idk
[19:12:46] <Bushman> so the problem emerges from the way the square profiles were welded together?
[19:12:47] <Frank__14> brb
[19:13:04] <Bushman> ok
[19:19:29] <Valen> howdy do andypugh been a while!
[19:20:34] <Valen> My Ultra100 drive seems to be dead :-<
[19:20:45] <Valen> Cant talk to it over serial any more
[19:29:47] <Bushman> Frank__14: when you get back, i made some drawings to help to illustrate the various misalignment scenarios
http://imgur.com/BjyxFf2
[19:31:02] <andypugh> Frank__14: This is what I mean:
https://ibin.co/2fTsaC84oSGB.png
[19:31:14] <Bushman> Frank__14: assuming the green plane is IDEAL, which case is the problem?
[19:32:08] <andypugh> My picture can fix most of, but not all of the problems in Bushman ’s pictures :-)
[19:32:28] <Bushman> oh no! my picture created unresolvable problems!
[19:32:38] <Bushman> is the universe gonna collapse?!
[19:32:40] <Bushman> ;>
[19:32:56] * Bushman is being silly
[19:33:04] <andypugh> Valen: Can you talk to it in any other useful way (clearly shouting at it is always possible, but not useful)
[19:33:23] <Bushman> shouting at it is also usefull
[19:33:32] <Bushman> it all depends on the goal
[19:33:34] <Valen> I would like to speak step-dir to it but I have no idea how it is configured in order to do so lol
[19:33:43] <andypugh> Bushman: I am just amused that we both went quiet at the same time frantically drawing
[19:33:47] <Bushman> if the goal is to reduce stress for example XD
[19:33:57] <Bushman> andypugh: lol, yea
[19:34:14] <Valen> Last time i touched it was in 2011 and I figure I probably tried to set it up for step-dir but have nfi what pins I would have told it to use
[19:34:19] <andypugh> My picture is better :-)
[19:34:40] <andypugh> Valen: Is there a factory reset?
[19:34:43] <Bushman> it's not better! it's just different
[19:34:52] <andypugh> I agree.
[19:34:53] <Valen> Plan -A is rip it apart and see if some crap got somewhere it shouldn't have, then try rs485
[19:34:58] <Valen> tried that
[19:35:18] <andypugh> Bushman: Yours probably imparts more informtional content.
[19:35:28] <Valen> the micro in it seems to be working because it flashes a LED at us if we unplug the motor from it
[19:35:35] <Bushman> heh, might be the case.
[19:35:57] <Valen> uphill battle both ways to get the software working to be able to talk to it lol
[19:35:58] <andypugh> Valen: That would bt the “stop disconecting the motor” LED?
[19:36:18] <Valen> andypugh: I think thats what rockwell name it internally
[19:36:45] <andypugh> Frank__14: Frank__15: Did you see the pictures?
[19:36:48] <Valen> I was wondering for plan-C would an 8i20 drive one of these
http://i.imgur.com/QpWBemq.jpg
[19:36:50] <Frank__15> andypugh: i thought the same idea when you said it to me, but (no offense) i think its too much work for me now that the structure is down and fully "aligned"
[19:36:53] <Frank__15> yes
[19:37:09] <Frank__15> you are awesome men haha
[19:37:30] <Frank__15> its the A scenariao
[19:37:32] <Frank__15> scenario
[19:37:57] <Valen> Bushman: your picture is a useful basis for discussion ;-> Also why is both rails parallel but a bit rotated from the plane an issue btw?
[19:38:05] <Frank__15> that's why i thought about moglice but i couldnt come up with the name at the time
[19:38:13] <andypugh> Frank__15: No point grouting a twisted rail. You need to set it true first
[19:38:27] <Frank__15> not the rail, but the feet, or the gantry
[19:38:59] <Frank__15> i have no acces to the bottom
[19:39:16] <andypugh> Ah, yes, you may be able to epoxy adjustable feet into the floor and twist the whole machine straight.
[19:39:17] <Frank__15> i would have to make holes the size of my fist (?)
[19:39:33] <Frank__15> ill make a quick draw to show what i mean
[19:40:07] <Valen> yes! I finally found something saying it has magnets in the damn thing
[19:40:14] <Valen> I thought it was an induction motor
[19:40:31] <andypugh> Valen: I reckon you could.
[19:40:49] <andypugh> Valen: What’s the feedback system from those?
[19:40:55] <Valen> hall I believe
[19:41:11] <Valen> and an ecoder
[19:41:12] <andypugh> Easy then
[19:42:07] <Valen> using it for a rotary axis through a 100:1 harmonic drive
[19:42:11] <Bushman> Frank__15:
http://imgur.com/aNotRr4
[19:42:14] <andypugh> Or you could use the Pico drives, or AMC or nearly anything
[19:42:30] <Frank__15> i am havinh issues like the A scenario
[19:42:38] <Valen> I have mesa everything, I love just plugging stuff in and having it work
[19:42:46] <Bushman> ok, A 2 or 3?
[19:42:55] <Valen> also the 8i20 I can wire straight to the wall which fills me with glee lol
[19:43:34] <Valen> I just upgraded the mill from 2.4 something to 2.7, the servo loop is so much better now? what's that about
[19:43:37] <andypugh> Valen: You can’t wire an 8i20 to the wall, it’s DC input
[19:43:46] <Valen> rectifier + big caps
[19:43:59] <andypugh> Yes, you can do that. I have twice now.
[19:44:03] <Valen> 240v mains here
[19:44:11] <andypugh> Here too :-)
[19:44:30] <Valen> I mean you should probably have an isolation transformer or something but geez, just don't lick the damn thing
[19:45:14] <andypugh> If you have a discharge resistor in your PSU and it is rated 50W 50 ohms and you connect it to 240V it fails in a balistic fashion, by the way.
[19:45:40] <Bushman> Frank__15: ok, new drawing:
[19:45:41] <Bushman> https://imgur.com/2CXU8L8
[19:45:44] <Valen> I imagine it smells funky too
[19:46:08] <andypugh> Valen:
https://picasaweb.google.com/108164504656404380542/Holbrook#6225711530252220498
[19:46:15] <Frank__15> lol, your fast men, im with rhino trying to make a quick scheme haha
[19:46:49] <Frank__15> case 3 would be the closest, but the 2 rails are in different angles
[19:46:50] <andypugh> SSRs, 2x8i20, mechanical discharge relay, rectifier, big cap.
[19:46:58] <Bushman> i see
[19:47:03] <Frank__15> lets say the left rail is 3 and the right is 1
[19:47:05] <Valen> mesa store says sold out of 8i20s
[19:47:37] <Bushman> Frank__15: so basically case 2?
[19:47:38] * Valen was looking for an exploded resistor ;->
[19:47:54] <Bushman> one is ok and one is rolling to the side?
[19:47:59] <Frank__15> anyone knows how to take a picture in rhino :D ?
[19:48:07] <Frank__15> yes bushman
[19:48:16] <Bushman> ok.
[19:48:16] <Valen> Frank__15: alt + print screen
[19:48:24] <malcom2073> Frank__15: snipping tool
[19:48:34] <Valen> imgur.com then ctrl+v
[19:48:53] <renesis> that works?
[19:48:55] <Bushman> so basically you need to make the left rail to lean more to the right?
[19:49:02] <Bushman> cause it's leaning to the left
[19:49:18] <Bushman> is "rolling" to the left
[19:49:21] <renesis> nice
[19:49:31] <Valen> Here's a question with the new version of linuxcnc, the tighter control loop is causing the LED's we have on the motor power bus to flare when its decelerating the table, so I figure its driving the DC bus over voltage, its being supplied from a pair of crappy 200W 12v supplies
[19:49:37] <andypugh> Valen: So are eusurplus, duzi.cz and mesaus.
[19:49:38] <Bushman> andypugh: that's where your picture comes in
[19:50:00] <Bushman> Frank__15: andy drew this:
https://ibin.co/2fTsaC84oSGB.png
[19:50:00] <Valen> I was thinking of making some kind of over voltage shunt thing, but is there a "better" way
[19:50:06] <Frank__15> uploadingg!!
[19:50:15] <Bushman> ok, waiting
[19:50:39] <Valen> I've looked a few times over the years they never seem to have them lol
[19:50:42] <Frank__15> i was just thinking of shiminh under the gantry, and leaving the rails in their angle
[19:50:57] <Frank__15> bad thing is i can only get bronze shimming
[19:51:02] <Frank__15> https://imgur.com/6Q0YcyM
[19:51:13] <andypugh> Any shim will do
[19:51:20] <Frank__15> orange is gantry, blue structure red rails
[19:51:34] <Bushman> Frank__15: yea, that makes sense
[19:51:40] <Frank__15> extrapolate to this, and boila (?)
http://imgur.com/HdkSmEJ
[19:51:42] <Tom_itx> _methods???
[19:52:22] <Bushman> Frank__15: how did you measure this "roll" of the rails?
[19:52:26] <andypugh> Valen: I just checked my pile of mesa cards, and I am out of 8i20s too.
[19:52:37] <Frank__15> Just really hope that i didnt messed up the blocks when testing with the bolts tightened, almost $500 usd there alone
[19:52:51] <Valen> we really should complain to managment ;->
[19:53:00] <Frank__15> 98-8 starret spirit level
[19:53:06] <Frank__15> its 8inch long
[19:53:06] <Bushman> Frank__15: let's hope that you didn't
[19:53:47] <Bushman> oh, so when you place a nice flat object on the rails, you can literally see they are not flat?
[19:53:59] <Frank__15> they started making a wired noise, then i took off the rails, cleaned them, installed them again, and (hopefully) they look good
[19:54:12] <andypugh> Frank__15: There is only one problem you can’t solve in softeare, and that is roll in the rails.,,,
[19:54:16] <Frank__15> not with the eye
[19:54:23] <Frank__15> Lol
[19:54:44] <Bushman> what angle are we talking about?
[19:55:06] <Bushman> 0.x° or 0.0x° ?:P
[19:55:41] <Frank__15> 180 seconds, idk how many degrees they are
[19:55:47] <andypugh> PCW: There appears to not be a single 8i20 for sale anywhere in the world right now?
[19:55:48] <Frank__15> :D
[19:56:13] <Frank__15> 0.05degrees looks like
[19:56:18] <Frank__15> (thanks google)
[19:56:35] <andypugh> Yes
[19:56:56] <Bushman> Frank__15: you realize that's negligible?
[19:57:09] <Valen> I'm not desperatley in need of one right this second, just feeling a bit defeated by the ordeal we went through to try to talk to the servo drive not working
[19:57:18] <andypugh> On 23mm that’s 0.0smm
[19:57:34] <andypugh> 0.02mm, I mean
[19:57:41] <Bushman> andypugh: how bout on 8'?
[19:57:43] <Bushman> :P
[19:57:58] <Bushman> Frank__15: how wide is your gantry again?
[19:58:07] <andypugh> Bushman: The 8” scale measured the angle.
[19:58:26] <PCW> there are some 8I20s being built now we should have them here and tested in a week or so
[19:58:29] <Bushman> digital tool?
[19:58:50] <Valen> PCW noice!
[19:59:04] <andypugh> it’s 0.177mm from one end of your level to the other but that really isn’t imprtant
[19:59:10] <Frank__15> not really :D that would make me happy, lol. but i did noticed the change in the blocks noise; and then with the rails not tightened i could see how the rails changed angles (in the level) when the gantry gets close
[19:59:20] <Valen> presuming this servo drive remains as dead as it appears to be I'll be getting one of those
[19:59:29] <Frank__15> maybe the width of the block would be important
[19:59:32] <Frank__15> 7cm
[19:59:46] * Valen surfs ebay for phat 600 v caps
[19:59:50] <Bushman> hmm...
[19:59:54] <Frank__15> 0.063 mm
[20:00:27] <Frank__15> thats why i think of shimming or grouting there,
[20:00:28] <andypugh> Frank__15: 0.02mm across the rails sounds like too much to me. It’s a tiny number, but more than the internal clearance of the balls in the blocks.
[20:00:49] <Bushman> hmm...
[20:00:49] <Frank__15> but i think shims make the joints to lose surface contact
[20:01:06] <Bushman> Frank__15: ok, some questions now:
[20:01:18] <Bushman> can you get it milled by someone?
[20:01:25] <Bushman> or grinded?
[20:01:27] <Frank__15> they already "are"
[20:01:42] <Frank__15> not the best solution right now,
[20:01:46] <Bushman> those were milled AFTER welding?
[20:01:53] <Frank__15> and after heat treating
[20:01:59] <Bushman> hmm...
[20:02:11] <Frank__15> thats the frustratin part.
[20:02:16] <andypugh> Valen: Your search term is “RIFA (400V, 380V)”
[20:02:33] <Frank__15> i did everything i could do to make things right, and all for nothing
[20:02:34] <Frank__15> lol
[20:02:42] <Bushman> you've got the whole frame heat-treated and precision milled? i'm impressed
[20:02:42] <Bushman> :D
[20:02:54] <Frank__15> really not precision milled..
[20:02:57] <Frank__15> just precision i would say
[20:03:03] <Frank__15> jsut milled i would say
[20:03:04] <Frank__15> lol
[20:03:08] <Bushman> heh
[20:03:21] <Frank__15> the gantry isnt perfect either
[20:03:31] <Frank__15> but bleh, for another day
[20:03:37] <Bushman> well, it's easier to fix the gantry now i giess
[20:03:40] <Bushman> *guess
[20:03:54] <Frank__15> i could get the hole 2.4mts to 0.15 mm height difference
[20:04:07] <Bushman> m not mts
[20:04:12] <Frank__15> yea, i ment the y rais
[20:04:14] <Frank__15> rails
[20:04:34] <Bushman> m is the unit, mts makes people confused (like it confuse me)
[20:04:36] <Frank__15> ill try with the shims, andy thinks bronze is fine
[20:04:37] <Valen> Father wants to make a router, steel welded construction, linear rails, would heat treating add much to the long term stability of it?
[20:04:47] <Frank__15> haha sorry, bad habit
[20:05:11] <Frank__15> i could tell you in like 10 years
[20:05:11] <Bushman> Frank__15: try with shims first, then USE your CNC to mill new, better quality shims
[20:05:31] <Valen> andypugh: hmm, thinking about it this existing servo drive must have some decent caps in it....
[20:05:40] <Frank__15> like stainless?
[20:05:41] * Valen looks at it in a threatening manner
[20:05:44] <Frank__15> maybe even tapered
[20:05:50] <andypugh> Frank__15: We have all been there. You do the right things, you get the wrong result, and you feel dispirited. Then a few days later the problem becomes the next interesting challenge.
[20:05:52] <Bushman> Frank__15: yes, tapered
[20:06:04] <Bushman> wedges esentialy
[20:06:13] <Bushman> with holes and stuff
[20:06:26] <Bushman> so you can have full surface contact
[20:06:51] <Bushman> Frank__15: also, have you painted the frame before or after installing the rails?
[20:07:06] <Frank__15> the idea of moglice is still picking in my head
[20:07:14] <Frank__15> before
[20:07:34] <Bushman> man, paint can be so uneven!
[20:07:51] <Bushman> if you need that kind of precision, put it on bare metal
[20:08:05] <andypugh> Frank__15: I am nt getting where you plan on putting Moglice. Moglise is a bearing material, but you already have bearings.
[20:08:08] <Frank__15> i tryed to clen everything before mounting, the rails are on steel
[20:08:10] <Frank__15> not paint
[20:08:22] <Duc> seems like Ive run into a snag with getting a techno cnc router table setup for a friend. Someone threw away the computer that had the cutom PCI card for it. I'm afriad what the card will cost
[20:08:25] <Bushman> ah, ok. good.
[20:09:17] <Frank__15> oh i see, i was thinking of the material that that guy madvak used
[20:09:17] <Bushman> Frank__15: then shim it for now and mill proper, tapered, full area spacers to correct for the problem
[20:09:30] <Valen> Frank__15: self levelling epoxy perhaps? get you close then you can sand it in place of scraping
[20:09:33] <andypugh> Duc: What card? On the plus side this gives you a good reason to switch to LinuxCNC and documented hardware
[20:09:49] <Valen> mesa have some cheap cards Duc
[20:10:15] <Duc> http://support.technocnc.com/Computer_card.htm
[20:10:24] <Bushman> Frank__15: good luck with your rig!
[20:10:43] <Duc> if this was for me, it would have been converted over to linuxcnc tonight but his computer skills are unknown
[20:10:57] <andypugh> Frank__15: I would actually be looking at actual grout, like tilers use, for a non-compressible filler under the rails once they are shimmed or adjusted straight.
[20:10:59] <Frank__15> thanks man, ill get back with some feedback!
[20:11:19] <Bushman> while i will retreat to my bed where i will roll from side to side, pretending to sleep for another 2 hours, after which i'll finally drop dead and wake up at 13:00 tomorow.
[20:11:24] <Bushman> g'nite everyone!
[20:11:32] <Valen> that first card looks like a parallel port card perhaps with some optos Duc
[20:11:37] <Duc> looks to be DC servo drives. dam nice table but I dont care to put that much time into it first
[20:11:46] <Frank__15> here u can read better the hole idea, just plug in epoxy in finder ctrl+f for me and gets you there
[20:11:47] <Frank__15> http://www.oneoceankayaks.com/madvac/machine_frame.htm
[20:11:51] <Duc> Valen: uses scsi cables
[20:12:42] <Valen> Duc:
https://www.google.com.au/search?q=25+pin+centronics+connector&client=ubuntu&espv=2&biw=1920&bih=919&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj9sPO4kbXMAhUkKaYKHWKcAUAQ_AUIBigB
[20:12:44] <Valen> those?
[20:13:52] <Duc> nope
[20:14:02] <Duc> let me take a pic real quick
[20:15:08] <andypugh> Duc: Internet says 250 Yen, but PLC center say £1433
http://www.plccenter.co.uk/Buy/TECHNO/H20T43PCI403?redirect=true
[20:16:00] <Duc> High density 50 - pin connectors
[20:16:11] <Valen> fairy nuff
[20:16:20] <Duc> andypugh: ouch it may end up with a conversion or being parted out
[20:16:54] <Valen> tried calling the manufacturer and asking them?
[20:16:55] <andypugh> Long or short card?
[20:17:27] <Duc> doing that on monday. Just realised the problem about an hour ago
[20:17:39] <Duc> no clue on card size
[20:18:15] <Duc> I got the system for free from work
[20:19:14] <Duc> we bought out a business so the assest was transfered to my old plant then we shutdown that plant. so it sat at the new plant till clean up day
[20:19:17] <andypugh> How good is your chinese?
http://www.web66.com.tw/CW1190/TECHNO-H20T43-PCI403-N1190924.html
[20:20:23] <Duc> good enough to check ebay. suprised the site isnt linked to ebay
[20:20:26] <Duc> no find
[20:24:17] <Duc> Might be able to use a 7i54 board to drive all the motors
[20:27:02] <Duc> Motor is a MCG P/N 2234-M4130 50oz-in 1.99amp
[20:43:49] <jdh> http://www.cnczone.com/forums/gecko-drives/288356-g320x-connection-help-needed.html
[20:43:53] <jdh> same motor
[20:48:33] <Duc> your google is way better than mine
[20:49:39] <andypugh> That’s one of those depressing threads where there is no resolution and you just know that the guy went for Mach3 and Gecke drives and steppers :-(
[20:50:07] <Duc> and its not like they put cheap stuff on the tables
[20:50:20] <Duc> THK rails, solid frame
[20:50:47] <andypugh> Tecno-Isel are a big name in linear slides
[20:51:10] <malcom2073> My dad has a techno-isel tabletop router, they're damn solid slides
[20:51:17] <andypugh> It’s going to be a quality machine, keep as much as you possibly can
[20:51:53] <jdh> worse, mach3, gecko step/dir servo drives
[20:52:08] <andypugh> I just bought anothet lathe chuck. I need to stop.
[20:52:26] <Duc> or at least put another quality servo system on it
[20:52:33] <Duc> I doubt he will put money into it
[20:53:19] <andypugh> jdh: I am not actually that set against step-dir servo drives. step/dir is just another interface layer, it is logically identical to +/- 10V except for the comms protocol.
[20:53:43] <jdh> and the lack of info to the control
[20:55:36] <Duc> this is made for cutting wood. +/- .005 would be a miracle
[20:58:14] <andypugh> I do like how this guy makes stuff. No CNC,
https://www.youtube.com/watch?v=nZsnGhwsjjo
[20:58:42] <Duc> I have wasted many hours watching his clocking making
[20:59:21] <malcom2073> I'm not clicking that
[20:59:24] <malcom2073> I know I'll watch an hour of it if I do
[20:59:43] <Duc> https://www.youtube.com/channel/UCw3UZn1tcVe7pH3R6C3Gcng
[20:59:46] <Duc> or this guy
[20:59:46] <andypugh> An hour is a very low estimate
[20:59:54] <malcom2073> andypugh: I'm going to bed in an hour
[21:00:22] <andypugh> malcom2073: You were, till we gave you the links
[21:00:31] <Duc> does a bunch of large manual machining
[21:00:31] <malcom2073> Nah the wife will make me haha
[21:01:47] <andypugh> malcom2073: Abom isn’t nearly so clever as clickspring. He’s a good machinist on big stuff, but not as imaginative.
[21:02:12] <Duc> nah since he has every tool imaginable expect cnc
[21:02:18] <malcom2073> I hope to be good enough to make worthwhile videos someday heh
[21:03:45] <Duc> I need a bigger shop first
[21:03:49] <andypugh> Actually, my favourite Youtube channel is
https://www.youtube.com/playlist?list=PLGSOZAHg1yQHU1tc_3Y5MTQg1qjtxA_nq which is actually watchable as a TV series.
[21:05:21] <andypugh> (In that, I watched them all on my TV with a FireTV stick and they worked as well as many of the broadcast programmes I watch. Their production values really are a class apart
[21:06:05] <Duc> I think ive seen a few of those also
[21:06:12] <Duc> youtube has come along way
[21:07:21] <Duc> some people produce better shows then companies do
[21:07:40] <djdelorie> clickspring's production quality is *amazing*
[21:08:11] <malcom2073> It's better than how it's made
[21:08:12] <malcom2073> heh
[21:08:20] <djdelorie> and that's saying a lot :-)
[21:08:34] <Duc> the guy must have OCD
[21:09:43] <Duc> I can do a project to 90% then stop
[21:11:54] <andypugh> djdelorie: Aye, I agree. He is always in focus, always speaks clearly. I have done a tiny bot of TV work and realise how hard it is to do it like clickspring and Badf Obsession do it.
[21:12:08] <djdelorie> his timing and pacing is excellent too
[21:12:22] <Duc> and his camera equipment is not the normal stuff
[21:13:09] <andypugh> Have you seen the few vidoos on my channel where I speak? You may guess why I rarely bother.
[21:13:34] <Duc> nah my speakers are blown on the laptop so I can only see the videos
[21:13:45] <djdelorie> have you seen all the videos on my channel, where I never speak? ;-)
[21:14:10] <malcom2073> djdelorie: link?
[21:14:21] <djdelorie> what, you want to watch me not say anything? ;-)
[21:14:36] <djdelorie> https://www.youtube.com/channel/UCzyUu7rVBhWC64_0J843uOA
[21:14:36] <andypugh> djdelorie: I don’t think I have ever seen any of your videos.
[21:14:45] <djdelorie> I mostly due photos
[21:14:57] <malcom2073> Psh, if you're making cool stuff who cares about talking :-P
[21:15:31] <malcom2073> Ah yeah I'd seen your channel, I think I had you link it before heh
[21:15:47] <zeeshan|2> andypugh's videos are more entertaining that clickspring
[21:16:19] <malcom2073> Hey zeeshan|2, you see my videos?
[21:16:24] <zeeshan|2> nop
[21:16:27] <zeeshan|2> maybe?!
[21:16:43] <andypugh> djdelorie: I was expecting gEDA stuff?
[21:17:02] <malcom2073> zeeshan|2:
https://www.youtube.com/watch?v=Ast5nnIlhFg
[21:17:10] <djdelorie> layout makes for boring videos, although the pcb drill test was a geda design
[21:17:39] <djdelorie> and the bldc driver boards were all geda:
http://www.delorie.com/photos/cnc/ http://www.delorie.com/electronics/bldc/
[21:17:40] <zeeshan|2> malcom2073: nice
[21:17:53] <zeeshan|2> why is your spindle stalling
[21:18:15] <andypugh> I was wondering that
[21:19:09] <malcom2073> zeeshan|2: I turned it down
[21:19:13] <andypugh> My mill is smaller and the spindle never slows even slightly unless there is smoke and/or shrapnell
[21:19:15] <malcom2073> it was melting a bit
[21:19:29] <zeeshan|2> youre not feeding fast enough
[21:19:31] <malcom2073> Right
[21:19:34] <zeeshan|2> for that spindle speed
[21:19:54] <malcom2073> I forgot to turn it down before running :)
[21:20:00] <djdelorie> I did some pcb milling (outline, not trace routing) and broke the first bit because I wasn't feeding fast enough
[21:20:13] <djdelorie> the FR4 melted and glued the bit to the pcb, locked it all up
[21:20:49] <zeeshan|2> malcom2073: have you tried going faster?
[21:20:49] <djdelorie> (it also wasn't an ideal bit for the task)
[21:20:52] <zeeshan|2> machine is rigid enough
[21:20:56] <andypugh> FWIW, this is me trying to do talking.
https://www.youtube.com/watch?v=ZhICrb0Tbn4 Verbal communication is not my strong point.
[21:21:07] <malcom2073> zeeshan|2: I've not gone faster with that endmill yet, I could go way faster
[21:21:10] <zeeshan|2> andypugh: why do you have an accent
[21:21:15] <malcom2073> I still wanna do the spring force test before I really push the machine
[21:21:27] <zeeshan|2> you degrees comes out scottish
[21:21:30] <malcom2073> Find out where the torque dropoff is
[21:21:30] <zeeshan|2> and the rest comes out english
[21:21:45] <andypugh> zeeshan|2: I have an accent because I was born somwhere where we have accents.
[21:21:54] <malcom2073> andypugh: Earth?
[21:21:59] <zeeshan|2> andypugh: you're supposed to make a smart ass come back
[21:22:05] <zeeshan|2> "to me YOU have an accent!"
[21:22:59] <andypugh> zeeshan|2: I have not heard you speak. If you speak like the Queen then you (by definition) have no accent ;-)
[21:23:07] <zeeshan|2> haha
[21:23:14] <zeeshan|2> you have heard me speak !
[21:24:04] <andypugh> No
[21:24:17] <djdelorie> anyone desperate to hear me speak can search youtube for "eevblog delorie" - Dave recorded some of my presentations
[21:24:30] <djdelorie> but they're not cnc related
[21:24:55] <andypugh> I kind of got hooked into re-watching Binky :-)
[21:24:55] <gregcnc> what was the discussion about the motor linked in G320 thread on cncnzone earlier?
[21:25:24] <zeeshan|2> djdelorie: what is geda
[21:25:32] <zeeshan|2> :P
[21:25:37] <djdelorie> GNU EDA software
[21:25:50] <zeeshan|2> too much abbreviations
[21:25:50] <djdelorie> basically, tools for designing circuits, simulating them, layout, etc.
[21:25:58] <zeeshan|2> is like altium
[21:26:00] <andypugh> PCB and Schematic stuffs
[21:26:05] <zeeshan|2> is it
[21:26:35] <zeeshan|2> ah it stands for "electronic design automation"
[21:26:43] <djdelorie> yeah, it's like altium - sorta like how harbor freight is to southbend
[21:27:06] <Duc> andypugh: gotta ask. what do you do for a living. Your toys seem fun and interesting
[21:27:08] <andypugh> Which is which :-)
[21:27:10] <zeeshan|2> i'm so far from microelectronics its great
[21:27:15] <zeeshan|2> the most i use at work is autocad electrical
[21:27:34] <djdelorie> geda produces stuff like this:
http://www.delorie.com/electronics/bldc/
[21:27:42] <andypugh> Duc: For a living I programme diesel engines.
[21:27:43] <zeeshan|2> oo nice
[21:28:02] <Frank__15> reALLY?
[21:28:12] <Frank__15> like the emma maersk? :D
[21:28:15] <Duc> gregcnc: I got a techno table with no controller card so we were looking into it
[21:28:30] <Frank__15> look andy, last page
https://tech.thk.com/en/products/pdf/en_b01_008.pdf#1
[21:28:42] <gregcnc> Duc and it has those encoders?
[21:28:48] <Frank__15> every manufacturer specifies height and paralelism tolerances not twist T_T
[21:29:11] <Duc> grepcnc: not sure yet but it is the same partnumber on the motor
[21:29:24] <Frank__15> are u behind the vW controversy? hehe
[21:31:20] <gregcnc> If it's a Dynapar or Danaher, it's very likely the model no. is on the face mated to the motor.
[21:31:52] <Duc> I will have to dig into the motor some more tomorrow. Sucks they trashed the computer system for it and I didnt notice they did
[21:32:07] <andypugh> Frank__15: Maybe you are OK then.
[21:32:57] <Duc> andypugh: Factory programming or more tuning customer vehicles? Come program my Duramax truck LOL
[21:34:04] <Tom_itx> zeeshan|2!
[21:34:15] <zeeshan|2> hi
[21:34:30] <andypugh> Currenlty I am working on an upgraded version of this:
https://www.youtube.com/watch?feature=player_embedded&v=pCsWm4cCMbs I mainly inser the link as it is interesting how engines are designed nowadays. Lots of unexpected parts like the ladder-frame to stiffen the bottom of the engine for noise reasons).
[21:35:51] <Duc> customers are very picky about noises nowdays and other small things
[21:36:21] <andypugh> Ues, NVH is my specialism.
[21:36:38] <andypugh> (typing is not(
[21:36:40] <Tom_itx> zeeshan|2 you get your parts all cu?
[21:36:53] <Tom_itx> t
[21:37:14] * Tom_itx blames the irc client
[21:37:23] <zeeshan|2> yes all delivered
[21:37:28] <zeeshan|2> ill be back, need to get food
[21:40:13] <Tom_itx> what timezone is _methods in?
[21:40:51] <_methods> est
[21:40:58] <andypugh> Duc: An interesting anecdote from about 30 years ago is that Ford had to recall a lot of cars for an engine mount change. Customer feedback was that they liked the extra power but didn’t like the reduced fuel economy. The engine itself had not changed, it just got quieter at higher revs because of the new mount, so customers were revving higher. But the only change was in the percieved engine note.
[21:42:14] <Duc> andypugh: Now that is funny. must are afraid to push a vehicle hard. Nothing wrong with red lining once in awhile
[21:42:47] <malcom2073> Most engines sound *scary* at high rpm unless you're used to the noise
[21:43:36] <Duc> I dont generally redline my duramax
[21:43:59] <malcom2073> I have a ford 5.4 in my expedition, I hate driving it above 3000rpm
[21:44:01] <malcom2073> it just sounds unhappy
[21:44:03] <andypugh> Duc: This was before cars had tachometers (and I am still fairly sure that most customers don’t look at, or understand the tachometer)
[21:44:40] <Frank__15> what about tesla ? :D
[21:45:16] <djdelorie> teslas come with a CD of "vroom vroom" sounds to make it sound like a real car... ;-)
[21:45:33] <Frank__15> lool
[21:45:41] <Duc> andypugh: I remember those days. Drove me freaking nuts. always added one to a car
[21:45:45] <Frank__15> like the bmw i3 or was it i9
[21:45:53] <Frank__15> they actually make engine sounds
[21:46:06] <Frank__15> with the speakers)
[21:46:14] <andypugh> malcom2073: It’s a wierd thing. At 4000rpm the “work” engines sound sad. At 4000 rpm my bike engine sound bored. They are both the same thing, 4 cylinders fastened to a crank. Why should they “feel” different?
[21:46:33] <malcom2073> andypugh: Because human brains suck :)
[21:47:05] <andypugh> Frank__15: Yes, well, so do normal cars now, Or they make anti-nise
[21:47:56] <andypugh> malcom2073: I think it might be because the engineers know their game.
[21:48:56] <andypugh> The bike is evil, the higher it revs the happier it sounds. And it revs to 14500 rpm.
[21:49:05] <Duc> happy sounds
[21:49:11] <andypugh> And that is 105mph
[21:50:39] <andypugh> (and proptionally faster in gears 2, 3, 4, 5, 6)
[21:52:27] <Duc> I miss my Ducati 848 EVO for those fast days
[21:53:10] <gregcnc> so a friend gave me ride on a 10yo 1100gsxr, it was terrifying and fun, but proabbly a good thing i avoided bikes til now.
[21:53:43] <gregcnc> i can see how easy it is to fall in love
[21:55:26] <gregcnc> he also showed me his Yamaha R1M, which we took to the shop for the 6th time
[21:57:48] <andypugh> My bike is a Yamaha R1. 2004 model, 103,000 miles.
[21:58:44] <andypugh> Still very fast, burns no oil. I seem no reason to change it.
[22:00:24] <Duc> how many accidents
[22:00:55] <andypugh> On track or off track?
[22:01:25] <Frank__15> do you build engines?
[22:02:49] <gregcnc> I think he had an R1 around that time too. he has a Grom, NSR80?, some big ugly kaw as well, he's a junky
[22:03:32] <andypugh> Duc: One big crash at a track-day highsiding at about 70mph 3 years ago. One embarasing rainy country lane crash at about 20 when the car in front stopped and I was looking at an interesting small bird last October.
[22:04:23] <andypugh> Frank__15: Are you asking me?
[22:04:43] <Duc> I was lucky to get away with none. Not sure how really. Albuquerque NM can be dangerous to ride at
[22:05:09] <Frank__15> i dont know, it was a general question hehe :D
[22:06:21] <andypugh> I can put an engine together, I do it quite often, but only for fun on engines made before about 1927
[22:08:30] <andypugh> With modern stuff it is hard to be sure that you are putting it back together better than it came apart, and the gaskets and seals cost som much that a rebuild costs more than bying an engine from a crashed bike.
[22:12:57] <Duc> seal kits are 500+ it seams
[22:13:53] <andypugh> Indeed, and I can pretty much guarantee thay any other R1 engine has a lower milage than mine.
[22:14:39] <Duc> amazing how long engines last now
[22:17:35] <andypugh> I have had 100,000+ mile bikes before, but they have all burned oil and felt tired. This one does not burn oil and is still properly fast on a track day (i go out in the fast group, and folk comment on how fast it is). It does sound like a bag of nails, though. :-)
[22:27:06] <Frank__15> wonder if its on porpouse
[22:33:11] <andypugh> The parts cost? I don’t think so. The cost is in getting the 2-cent washer into a labelled bag at the local dealer on the other side of the world, and ensuring that when it gets there it is the correct 2-cent washer.
[22:33:44] <andypugh> Time to sleep
[23:31:18] <XXCoder> zeeshan|2: is it you in xfce mint channel lol
