[03:15:39] <Deejay> moin
[03:24:46] <zeeshan|2> anyone know why this would be happening:
[03:24:47] <zeeshan|2> https://www.youtube.com/watch?v=Nq5pbW9m78A
[03:27:27] <archivist> two words come into mind, hunting, it cant decide, drift slowly moving
[03:28:47] <archivist> noise and/or bad connection possibly
[03:28:51] <zeeshan|2> why doesnt the glass scale update?
[03:28:55] <zeeshan|2> it was working fine before?
[03:29:01] <zeeshan|2> just started tonight
[03:29:18] <archivist> bad connection? dirty scale
[03:29:31] <zeeshan|2> hm
[04:43:24] <XXCoder> zeeshan|2: yo
[07:35:22] <jthornton> lol, I uninstalled gnome and it removed linuxcnc
[07:37:05] <herron_> ask for your money back
[07:46:57] <_methods> does that mean gnome is a dependency of linuxcnc lol
[07:56:11] <MrSunshine> hmm coolant for engraving aluminium that is not flammable? =)
[07:56:43] <MrSunshine> and no . .cant oil flood or something like that .. nor use pure water for example
[07:57:38] <jthornton> quick silver
[07:58:15] <archivist_herron> coolant or lubrication
[08:57:48] <Simonious> I'm sad that Trimble seems to be killing Sketchup. I think if they had sold $20-$50 support packages they'd have saturated every school and taken off like a rocket. Instead they put key features like DXF export into the pro version and want $590 for it. This will force me to use a different tool in my software chain and I really like Sketchup. Honestly I'm likely to switch to SolidWorks, which costs more, but Sketchup
[09:00:41] <archivist> some sellers do not understand 100*590 < 10000*59
[09:02:15] <Simonious> It's such an old, tired, sales, model. I'd have paid the amounts I suggested for support. Even people who prefered SolidWorks would have tossed that much at them just to check it out.
[09:02:16] <archivist> they prefer the "Apple" price of what the market will bare
[09:04:05] <Simonious> In fairness it seems to be working for Apple, but Apple has one of the better product lines out there. Sketchup is in a highly competitive area and it isn't in the heavyweight league.
[09:04:59] <Simonious> Sketchup had so much momentum a couple years ago. Heck they changed how many people think about and use computers.
[09:06:01] <archivist> are you sure, google never dumps a winner as far as I know
[09:06:14] * Simonious ponders
[09:07:18] <archivist> Solidworks has been through a few owners, or at least two
[09:08:12] <Simonious> SketchUp was initially meant to spur crowdsourcing of 3D city models
[09:08:43] <Simonious> But Google has since realized they can create 'real' 3d models with their mapping cars
[09:20:25] <Simonious> Kinda neat right? within a few years we'll have up to date HD 3d models of.. everything.
[09:20:42] <Simonious> You know... probably.
[09:22:03] <Simonious> put your VR rig on.. fly to anywhere in Google Earth.. See the world as it really is.
[10:39:27] <_methods> http://phx.corporate-ir.net/phoenix.zhtml?c=176060&p=irol-newsArticle&ID=2028891
[10:39:30] <_methods> wow
[10:39:38] <_methods> unlimited cloud storage.....
[10:43:22] <ssi> hm
[10:43:53] <_methods> $12/year for unlimited pics
[10:44:02] <_methods> which is pretty damn cool
[10:44:12] <_methods> be nice to have a back up to my back up for family pics
[10:44:17] <ssi> yeah, hopeully it has a decent interface both for uploading and for sharing
[10:44:29] <_methods> knowing amazon i doubt that lol
[10:44:29] <ssi> I can't believe that in 2015 there's still relatively few ways to do that
[10:44:44] <ssi> about the only thing I use twitter for is pictures
[10:44:52] <_methods> not sure why no one can be as good as dropbox
[10:44:55] <ssi> it's about the fastest way for me to take a picture on my phone and give someone a link
[10:45:09] <ssi> unfortunately it SUCKS as a photo archive
[10:45:15] <_methods> hehe
[10:45:23] <ssi> I can give you the link to a pic I Took today, but if I want to give you a link to one I took two months ago, it's abject misery
[10:45:26] <_methods> i have tried many photo archives
[10:45:31] <_methods> none make me very happy
[10:45:33] <ssi> because of the "scroll and load more" web interface
[10:45:35] <ssi> exactly
[10:45:59] <_methods> they all screw soemthing up
[10:46:24] <_methods> wow i guess that pilot ran that plane into the ground
[10:46:28] <ssi> yep
[10:46:39] <ssi> prepare for the screams for psych screening
[10:46:45] <ssi> that's going to be super fun
[10:46:46] <ssi> :(
[10:46:56] <SpeedEvil> Especially as psych screening isn't a thing.
[10:46:58] <archivist> do your own system, I can find my old pics
[10:47:17] <ssi> archivist: cobbler's kids and all
[10:48:06] <_methods> well the one thing all of the photo systems i've used screw up is being able to upload and share links easily
[10:48:16] <archivist> google is moaning that my stuff is not "mobile friendly"
[10:48:34] <SpeedEvil> archivist: Hold the camera the wrong way, and shake it more
[10:48:46] <ssi> _methods: yes exactly
[10:49:00] <_methods> if they get one right they screw up the other lol
[10:49:18] <_methods> so now i basically just use dropbox then push to imgur
[10:49:20] <ssi> I've thought about continuing to use twitter for my uploading the way I do
[10:49:28] <_methods> a lot of people don't trust dropbox links
[10:49:31] <ssi> but then write an app that scrapes pics from twitter and puts them in a better frontend
[10:50:10] <_methods> i wonder if imgur has an android app
[10:50:46] <_methods> oh wow i guess i could just use that app on imgur
[10:50:54] <_methods> and skip the whole dropbox thing hehe
[10:50:55] <ssi> which app
[10:51:06] <_methods> they have an official imgur app
[10:51:22] <archivist> you could use a proper camera
[10:51:28] <ssi> that only makes it harder
[10:51:30] * archivist ducks
[10:51:42] <_methods> chrome and firefox extensions
[10:52:10] <_methods> well shiznit guess i should just be using imgur
[10:52:11] <ssi> proper cameras haven't even come up with the wherewithal to put gps receivers in them for geotagging, let alone reasonable network integration
[10:53:52] <_methods> oh damn this is messed up
[10:53:54] <_methods> http://i.imgur.com/4kXGwpN.png
[10:54:36] <ssi> daaaaaaaan
[10:54:37] <ssi> g
[10:54:58] <_methods> heheh
[10:54:59] <_methods> so wrong
[10:56:38] <_methods> wow i gotta applaud imgur
[10:56:48] <_methods> you don't even have to have an acct to use their app
[10:57:01] <_methods> don't even have to register
[11:00:42] <ssi> http://imgur.com/topic/Funny/6Ldtx
[11:01:26] <_methods> heheh gummi dicks
[11:01:59] <_methods> poor gummi bears
[11:02:12] <_methods> that's a lot of gummi castrations
[11:02:20] <ssi> hahaha
[11:18:39] <_methods> yeah damn i should have just been using imgur the whole time
[11:18:44] <ssi> lol
[11:38:08] <zeeshan> pcw: any opinions on this: https://www.youtube.com/watch?v=Nq5pbW9m78A
[11:38:45] <zeeshan> dirty encoder?
[11:40:48] <cradek> that's normal dithering if your resolution is .0004
[11:41:00] <cradek> you can sometimes, but not always, tune it out or at least slow it down
[11:41:13] <zeeshan> yes but loook @ the encoder
[11:41:15] <zeeshan> er
[11:41:19] <zeeshan> dial indicator..
[11:41:25] <cradek> oh it's creeping!
[11:41:25] <skunkworks> it is walking... noise?
[11:41:28] <cradek> forget what I said
[11:41:28] <zeeshan> its moving a lot more than the dro is recognizing
[11:41:31] <cradek> yeah that's noise
[11:41:38] <_methods> anyone in here ever buy one of those square hole drills?
[11:41:56] <zeeshan> that what boggles my mind cause its been working great for the last couple of weeks?
[11:42:01] <zeeshan> and then it did this all the sudden
[11:42:09] <zeeshan> its shifting upto .100"
[11:42:13] <cradek> maybe you lost a ground somewhere
[11:42:19] <_methods> i got a job that isn't high enough qty to get a rotary broach tool for
[11:42:29] <_methods> but one of those sq drills might work
[11:42:57] <zeeshan> http://i.imgur.com/0goQRLO.png
[11:43:03] <zeeshan> this is what the trace looks like of the encoder
[11:43:04] <cradek> put a real scope on the encoder lines?
[11:43:06] <_methods> i can't seem to find anyone that sells the drill bits though
[11:43:07] <ssi> _methods: how much is a rotary broach
[11:43:32] <zeeshan> you can see this constant line
[11:43:40] <zeeshan> constant oscillation it looks like
[11:43:45] <_methods> couple thousand
[11:43:50] <_methods> for the cnc lathe one
[11:43:54] <ssi> eep
[11:43:55] <_methods> but this order is small only 8 parts
[11:44:07] <_methods> but could turn into thousands
[11:44:14] <_methods> and for that we'll buy the rotary broach
[11:44:25] <_methods> but for only 8 we were trying to keep it cheap
[11:44:34] <cradek> is the encoder differential?
[11:44:35] <zeeshan> is there any chance it could be a dirty encoder?
[11:44:38] <pcw_home> zeeshan: Check you encoder --> interpolator connections and interpolator --> 7I77 connections
[11:44:43] <_methods> hmm this guy did a diy rotary broach
[11:44:44] <_methods> i might try that
[11:44:49] <cradek> maybe you lost half of a channel
[11:44:54] <_methods> https://www.youtube.com/watch?t=18&v=M3Ul-s9_MA0
[11:45:01] <zeeshan> cradek yes it is differential
[11:45:05] <pcw_home> could be a dirty scale
[11:45:07] <cradek> but it's really probably just wiring/grounding/noise
[11:45:58] <archivist> zeeshan, three of use singing from the same hymn sheet I think
[11:46:08] <_methods> guess i'll just make a rotary broach like that
[11:46:11] <cradek> I bet a real scope will point you right at it
[11:46:19] <zeeshan> what is confusing is how an absolute encoder can shift .100"
[11:46:26] <zeeshan> wouldn't it pick up the counts
[11:46:31] <zeeshan> and compensate?
[11:46:39] <archivist> there is a disconnect of the data
[11:46:40] <evil_ren_> weird interference, is like ~2 and ~20 khz
[11:46:44] <ssi> it's only absolute to the interpolator, right?
[11:46:48] <pcw_home> Yeah for analog scale output you need a scope
[11:47:00] <pcw_home> its not absolute
[11:47:21] <pcw_home> just sine/cosine
[11:47:24] <ssi> oh they're analog scales
[11:47:39] <skunkworks> who has cheap 1um scales?
[11:47:48] <zeeshan> skunkworks: sino makes some nice ones
[11:47:55] <pcw_home> sine/cos analog --> interpolator --> quadrature
[11:47:55] <archivist> I has no scales
[11:48:05] <zeeshan> okay so if the analog signal is messed
[11:48:12] <zeeshan> it loses its ability to track
[11:48:19] <archivist> yes
[11:48:38] <pcw_home> yes that a possibility (and oil/dirt might cause this)
[11:49:02] <zeeshan> ill start with the easy stuff -- try to borrow a scope and measure the analog input
[11:49:08] <zeeshan> and check the connections
[11:49:14] <zeeshan> then go through the pain of cleaning the scale :p
[11:50:06] <zeeshan> would i pick up dirt by observing the wave on the scope too?
[11:50:23] <zeeshan> some sort of distinct pattern would show up?
[11:50:45] <archivist> noise rather than a nice distinct pattern
[11:50:59] <pcw_home> are these 11 uA scales or 1V scales?
[11:51:22] <archivist> if all along the scale then unlikely dirt on the scale
[11:52:08] <zeeshan> its worse in some locations
[11:52:09] <zeeshan> then others
[11:52:16] <zeeshan> but happens msot of the itme
[11:52:49] <pcw_home> could be a dirty scale /read head
[11:52:52] <archivist> the bulb/led/opto dirty rather than scale
[11:53:07] <pcw_home> (or a bunch of other things)
[11:53:26] <archivist> scope and diagnosis
[11:53:28] <zeeshan> they are 11uA scales
[11:53:47] <pcw_home> could be a bad interpolator but they are pretty simple so unlikely
[11:54:40] <pcw_home> check read head 5V also
[11:54:55] <zeeshan> @ the physical scale?
[11:55:07] <zeeshan> or at the output of the interpolator
[11:55:18] <ssi> zeeshan: do you have only the scales, or do you have shaft encoders also?
[11:55:23] <zeeshan> ssi just scales
[11:55:26] <ssi> ok
[11:57:35] <pcw_home> to test the scales analog with a scope out you need to disconnect them from the interpolator and put a ~10K load across the _-sin and +-cos pins
[11:57:51] <pcw_home> +-sin
[11:58:19] <zeeshan> and rotate the axis by hand?
[11:58:25] <pcw_home> yes
[11:58:43] <zeeshan> im looking for a rigol 1052e :)
[11:58:51] <cradek> scope in XY mode would be very telling
[11:58:52] <pcw_home> and look for clean sine/cosine waveforms on a 2 channel scope
[11:59:11] <pcw_home> Yeah should be a nice circle
[11:59:20] <pcw_home> (in X/Y mode)
[12:00:20] <pcw_home> but check connections first
[12:02:03] <archivist> wouldnt be the first time that one finds oops did not tighten that screw properly, or some bit of stranded, screw is tight but not gripping the wire
[12:04:19] <zeeshan> usually icheck wire connections by measuring continuity
[12:04:25] <zeeshan> between two points
[12:05:30] <archivist> I give them a light tug after tightening
[12:05:39] <zeeshan> the connections on the interpolators
[12:05:43] <zeeshan> are silly molex connectors
[12:05:45] <zeeshan> nothing to tighten :/
[12:05:56] <pcw_home> you could swap interpolators to check that there's not a problem there
[12:06:52] <pcw_home> ( I would do these tests manually with drives disabled )
[12:07:46] <zeeshan> the first test im gonna do (since i won't be able to get a scope tonight) is go to linuxcnc with machine power off button
[12:08:02] <zeeshan> and rotate the y-axis by hand and monitor encoder counts
[12:08:27] <zeeshan> if its not counting, then i will check the connections
[12:08:31] <zeeshan> or if its counting funny
[12:08:45] <zeeshan> and if connections are fine then i will need a scope :/
[12:09:01] <zeeshan> i can also try cleaning it too
[12:09:04] <zeeshan> while i wait for a scope.
[12:10:06] <zeeshan> btw guys, this is the axis which has been making a weird bearing noise :p
[12:10:24] <zeeshan> i know it's not on the motor because i've had the motor off and running at high speeds
[12:10:41] <zeeshan> and i can only replicate the noise higher than 100 ipm
[12:36:57] <pcw_home> hope that weird noise was not the scale scraping :-(
[12:49:14] <zeeshan> i hope not
[12:49:17] <zeeshan> it really sounds like a bearing noise
[13:26:57] <tjtr33> zeeshan, you can drive the screw with a hand drill to see if noise is there.
[13:27:08] <tjtr33> you can pull 1 end of scale open and pour 95+% alco thru to clean scale.
[13:27:15] <tjtr33> you can swap interpolators and even scales to debug
[13:27:18] <tjtr33> ( careful! jog slow and near ctr of travel )
[13:27:55] <tjtr33> a scope wil have difficulty to not load the 11uA signal and the Z phase is even less. 5uA iirc
[13:28:51] <PCW> you need to load the 11 ua ( 10K max)
[13:29:01] <tjtr33> oh the head attitude to the glass is critical, get the Heidy docs for allignment
[13:29:28] <PCW> its a solar cell so ideally works into a short
[13:33:16] <tjtr33> PCW, is the ~<10K across the pair? ( i imagine a short is like 0ohm across pair )
[13:34:34] <ssi> dead short won't let it develop any voltage
[13:35:23] <tjtr33> i didnt understand the 'like solar cell' analogy a-tall
[13:36:21] <PCW> dead short into a current to voltage converter is the ideal sensing system
[13:36:45] <ssi> yeah but across a zero ohm resistor it's gonna be tough to see on a scope
[13:37:23] <PCW> 10K is not bad (110mv max)
[13:38:15] <PCW> the lower the resistance the better the linearity
[13:44:58] <archivist> a current probe :)
[13:45:18] <ssi> psh
[14:04:22] <Cromaglious> morning
[14:34:18] <luiscr> Hello everyone, I have a random question about the Mesa 7I43H, is that card supported on linuxcnc? If so, how? Does the linux kernel have some kind of realtime variant of the usb subsystem?
[14:35:09] <__rob> hello
[14:35:57] <Cromaglious> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Mesa_Cards
[14:36:12] <__rob> http://www.parkersteel.co.uk/Matrix/60/Bright+Flat+Metric
[14:36:13] <__rob> http://www.parkersteel.co.uk/Product/0048089/Mild+Steel+Flat/200+X+25mm+EN10025+S275JR
[14:36:24] <__rob> can anyone tell me why the price between those 2 is so hugely different
[14:36:33] <__rob> 500mm of 200mmx25mm
[14:36:46] <__rob> £139 vs £30 for bright
[14:36:47] <Cromaglious> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Mesa_EMC_2_Integration
[14:36:47] <PCW> luiscr: Not with standard linuxcnc (Arais Robo has branch using USB)
[14:37:42] <LeelooMinai> USB latencies are in milliseconds though
[14:37:51] <PCW> Ethernet is possible though with Linuxcnc 2.7
[14:38:22] <LeelooMinai> USB is not exactly realtime anything:)
[14:38:47] <PCW> Arais Robo uses a special FPGA config with a processor doing the critical real time duties
[14:40:20] <_methods> you mean why is bright steel more expensive than standard mild steel?
[14:40:28] <__rob> no, its the other way round
[14:40:40] <__rob> when I add to basket
[14:40:46] <_methods> hmm
[14:41:26] <_methods> i have no idea you'd have to call them
[14:41:38] <_methods> they probably have something screwed up in their shopping cart
[14:42:06] <__rob> well
[14:42:08] <__rob> might just order it
[14:42:10] <__rob> and see then
[14:42:12] <__rob> if thats 'cheap'
[14:42:42] <XXCoder> heh once tried to buy $1000 tv for $10 (pricing error) but I got gift card of $50
[14:42:44] <_methods> 30 isn't bad i don't think for such a small piece
[14:42:49] <XXCoder> I bought some dvds with it
[14:42:56] <__rob> http://i.snag.gy/DjSDs.jpg
[14:43:15] <__rob> I want to use it as a backplate for a zaxis I've been given
[14:43:18] <__rob> to replace my current one
[14:43:36] <_methods> heh i think they just screwed up
[14:44:42] <__rob> will that be ok for a z axis back plate ?
[14:44:45] <__rob> 25mm
[14:45:08] <_methods> i would think so
[14:45:20] <_methods> is that for x2 or something?
[14:45:52] <__rob> the basket above was just 2 different options of the same peice
[14:46:00] <__rob> I will buy 2, and some cast iron angles
[14:46:05] <__rob> to make a big 'L'
[14:46:15] <__rob> and was gonna bolt, http://snag.gy/1b6Fz.jpg, to the back plate
[14:46:20] <__rob> weighs quite a bit
[14:46:48] <__rob> hopefully 25mm will be solid enough with cast iron angles holding it upright
[14:47:42] <__rob> not really used alot in the way of thick steel, so hard to know what is over/under engineered
[14:48:53] <_methods> yeah 30 is a gud deal
[14:49:02] <_methods> i'd hit buy on that one lol
[14:49:49] <__rob> yea, but in terms of stregth for a z axis ?
[14:50:22] <_methods> oh well i have no idea what your application is so i couldn't tell you
[14:50:45] <__rob> well holding up right the 30kg of the above image
[14:50:51] <__rob> or wahtever it weighs
[14:51:00] <__rob> without any spring
[15:24:16] <Cromaglious> My 400w spindle just showed up
[15:24:28] <_methods> pew pew
[15:24:37] <_methods> make some chips already
[15:25:52] <Cromaglious> looks to have a 8mm shaft vs 5mm on the 300w
[17:23:47] <Deejay> gn8
[17:41:04] <dirty_d> any of you know how to set up a gamepad for jogging?
[17:41:10] <dirty_d> i have POSTGUI_HALFILE = postgui.hal in my ini file
[17:41:33] <dirty_d> and http://codepad.org/8RxSfIve in postgui.hal
[17:41:51] <dirty_d> input.0.btn-c is the circle button on my PS4 controller
[17:42:00] <dirty_d> it shows up and works in hal meter
[17:42:36] <dirty_d> my intention was for that code to jog the x axis 0.001 every time the circle button is pressed, but nothing happens
[17:45:51] <dirty_d> hmm, adding setp halui.jog-speed 10 made it work
[21:32:14] <Cromaglious> OK found some XH4p plugs w/ 30cm cables, makes it easy to hook up driver boards to the breakout
[22:50:19] <zeeshan> hey guys
[22:50:25] <zeeshan> i started the cnc mill
[22:50:35] <zeeshan> moved the y axis by hand and the encoder counts fine.
[22:50:56] <ffurrywol> ok
[22:51:01] <zeeshan> i started the system and its working fine now?
[22:51:01] <zeeshan> wtf
[22:51:38] * ffurrywol must have missed a past conversation on this topic
[22:54:07] <zeeshan> yes you did :-)
[22:56:03] <ffurrywol> last I remember you talking about your mill, you said it was working great, and you'd done several odd jobs on it.
[22:56:16] <AndChat|144384> That sucks
[22:56:52] <zeeshan> i have
[22:56:56] <zeeshan> and then you jinxed me
[22:57:00] <zeeshan> er thats not ther right one
[22:57:16] <zeeshan> you evil eyed me
[22:57:18] <zeeshan> !
[22:57:24] <zeeshan> hi pcw!!!
[22:57:56] <zeeshan> moved the y axis by hand and the encoder counts fine. i started the system and its working fine now.. what is going on?!
[22:57:59] <zeeshan> i havent changed anything
[22:58:29] <zeeshan> i hope it doesnt run away
[22:58:32] <zeeshan> randomly again
[22:59:04] <pcw_home> Bad connection, or thermal intermittent maybe
[22:59:55] <pcw_home> what version of linuxcnc are you using?
[23:00:16] <zeeshan> 2.6
[23:00:34] <zeeshan> in ubuntu though
[23:00:38] <zeeshan> not debain
[23:00:44] <zeeshan> *debian
[23:01:24] <zeeshan> i didnt touch the connections
[23:01:33] <zeeshan> i literally started up the system today
[23:01:59] <zeeshan> and did the test i said i was going to try before checking connections
[23:02:42] <pcw_home> could still be a loose connection or bad cable
[23:03:35] <zeeshan> hm
[23:03:38] <zeeshan> that'll be hard to figure out
[23:03:57] <zeeshan> maybe the scale is dirty
[23:04:01] <zeeshan> and the piece of dirt fell off with time? :p
[23:04:03] <zeeshan> i dont know
[23:04:22] <zeeshan> if it gives me problems again
[23:04:25] <zeeshan> ill clean it up
[23:04:37] <pcw_home> not sure if its in 2.6.X but check if the pin hm2_5i25.0.encoder.01.quad-error exists
[23:04:44] <zeeshan> yes it exists
[23:05:16] <pcw_home> what about hm2_5i25.0.encoder.00.quad-error-enable
[23:05:26] <zeeshan> https://www.youtube.com/watch?v=Nq5pbW9m78A
[23:05:26] <zeeshan> yes
[23:05:28] <zeeshan> they are both there
[23:05:35] <zeeshan> :12
[23:06:43] <zeeshan> btw i advertised mesa today at the local maker space: -)
[23:06:51] <pcw_home> OK so if set hm2_5i25.0.encoder.NN.quad-error-enable true (maybe with drive enable) you can check for funny business on the quadrature lines
[23:06:55] <zeeshan> they were telling me they dont run linuxcnc cause it doesnt have feedback :)
[23:07:09] <zeeshan> what will it show me pcw_home
[23:07:33] <pcw_home> if there have been any quadrature state errors
[23:08:24] <zeeshan> damn it, i wish i did that yesterday
[23:08:27] <pcw_home> a crazy interpolator, noise or a bad connection is liable to generate a state error
[23:08:35] <zeeshan> what about dirty scale
[23:08:51] <pcw_home> possibly
[23:09:28] <zeeshan> im gonna let the machine sit around for a while and test again in a bit
[23:09:32] <pcw_home> state error basically means A and B changed at the same time
[23:09:58] <zeeshan> hm, that shouldnt happen if the scale is dirty
[23:09:58] <pcw_home> (which is illegal for quadrature)
[23:10:26] <pcw_home> not sure what the interpolator does with bogus input
[23:11:49] <pcw_home> is it possible you had condensation on the scale?
[23:13:11] <zeeshan> that could be a possibility
[23:13:25] <zeeshan> cause garage was 3C when i entered
[23:13:40] <zeeshan> and it went to 22C by the time i was running the machine hard
[23:15:45] <skunkworkss> Interesting idea
[23:18:31] <ffurrywol> I wish I could start a makerspace...
[23:18:41] <zeeshan> i went to the local one today
[23:18:43] <zeeshan> decent guys there
[23:18:51] <zeeshan> ffurrywol: mvoe here :D
[23:19:23] <bobo_> zeeshan electric blanket for your mill when not being used ? and my cat would crush your wimpy bridge !
[23:19:36] <zeeshan> lol
[23:23:11] <bobo_> zeeshan there is available --spray cans of circuit freeze , also on Pract-Mach web site search for Heidenhan scale cleaning
[23:24:14] <zeeshan> trying to avoid cleaning them right now :)
[23:24:19] <zeeshan> till i absolutely have to
[23:24:24] <zeeshan> need to make parts!
[23:26:03] * furrywolf knows absolutely nothing about scales, having filed them under bits only unaffordable machines have
[23:27:48] <Cromaglious> well hopefully, I'll get over to the Creatorspace.us tomorrow and install the 400w spindle.
[23:28:09] <Cromaglious> hopefully I'll be unsick enough to do that
[23:29:01] <Cromaglious> I really need to start building my table and gantry for my home cnc
[23:30:11] <bobo_> zeeshan think I saw $325 (could have been less $ ) for place in Calif. (Real Heidenhain shop ) for clean and replace seals and check calibration of scales
[23:30:24] <pcw_home> the really unaffordable machines have Renishaw resolute scales
[23:30:44] <zeeshan> bobo its just glass :P
[23:30:46] <zeeshan> windex!
[23:31:57] <bobo_> a diamond is "just glass " also
[23:32:11] <zeeshan> i found a guide on how to clean em
[23:32:29] <zeeshan> lint free swabs
[23:32:34] <furrywolf> just about everything is unaffordable for me. bleh.
[23:32:37] <zeeshan> and lint free cloth and clear windex tis what they recommend
[23:33:38] <bobo_> was looking today for the cleaning instructions ----- still looking
[23:34:00] <Cromaglious> sheesh... 6090 cast bed + cast AL gantry parts, Z carriage for $395, shipping though is $792.08
[23:34:39] <bobo_> windex is prone to leave a smear
[23:34:49] <Cromaglious> windex has wax in it
[23:35:01] <zeeshan> http://dealertraining.cat.com/jobaids/elpdf/eu03dja.pdf
[23:35:12] <zeeshan> that is what ill follow
[23:35:17] <zeeshan> if i do it
[23:36:47] <furrywolf> I make marginally over minimum wage, live in a shack, and still can barely afford food, much less toys. how the hell do people making minimum wage, working retail, etc manage to live?
[23:39:08] <skunkworkss> Pay day loans
[23:40:33] <furrywolf> that doesn't give you more money. that gives you less.
[23:43:40] <bobo_> Zeeshan Where did you find that cleaning thing on my computer ? been looking for it most of today
[23:44:53] <zeeshan> :)
[23:49:37] <renesis> furrywolf: roommates, families, and lower standards of living
[23:49:48] <tjtr33> heidenhain schaumberg illinois is usually ~100$ to inspect & certify an encoder or scale. (test and certify, NOT repair ). i do it on every scale/encoder i use for repairs.
[23:50:33] <furrywolf> my standard is pretty low. heh.
[23:50:43] <renesis> youre on irc, its not that low
[23:51:41] <furrywolf> I'm on irc on an old marginal laptop, with a 3g connection because I can't get real internet this far out in the woods where shacks are cheaper
[23:51:43] <renesis> roommates and families are the big ones, tho
[23:52:05] <renesis> you have a cell phone with a data plan, your standard of living is not that low
[23:52:44] <furrywolf> everyone does. even if I didn't pay for it, the government gives you one now.
[23:52:52] <renesis> also you had a credit car with enough available credit to buy a round trip plane ticket
[23:52:55] <renesis> youre doing okay
[23:53:05] <renesis> and no furrywolf, thats what im trying to say
[23:53:08] <renesis> not everyone does
[23:54:01] <furrywolf> they even have booths here in front of stores giving free cell phones to useless people
[23:54:30] <zeeshan> tjtr33: did you see what i wrote earlier?
[23:54:32] <bobo_> zeeshan what would you guess the cost might be to install a small fan exausting house air into your garage
[23:54:34] <zeeshan> that it started working on its own
[23:54:41] <renesis> inner city low standard in high population density, high crime areas is considerably lower than rural living in arguably one of the most beautiful places on earth
[23:54:59] <tjtr33> zeeshan, several things , which?
[23:55:06] <renesis> not trying to be argumentative, but youre doing okay, could be doing much, much worse
[23:55:12] <zeeshan> that it started working on its own! :P
[23:55:13] <furrywolf> I still haven't made indoor plumbing really work yet.
[23:55:22] <tjtr33> you going to use the PWM7 ? http://www.practicalmachinist.com/vb/general-archive/oscilloscope-gurus-how-check-dro-scales-spec-sheets-attached-85553/
[23:55:30] <furrywolf> I got a craigslist water heater, then realized all the pipes had to be replaced...
[23:55:55] <renesis> ha oscilloscope guru, funnt
[23:56:03] <renesis> that sounds like screwdriver guru to me
[23:56:16] <zeeshan> tjtr33: you got one? :)
[23:56:17] <zeeshan> let me borrow it!
[23:56:48] <tjtr33> no, outta my $ range, i have a 3 led tester we made tho, checks 11uA but not amplitude nor frequency
[23:57:04] <zeeshan> whats the deal with alignment?
[23:57:09] <renesis> you dont have $50?
[23:57:10] <zeeshan> basically if you unbolt the scale from the machine?
[23:57:13] <zeeshan> its screwed?
[23:57:19] <tjtr33> the reader heqad on any scale is critical
[23:57:26] <zeeshan> yes, but how do you align that?
[23:57:36] <zeeshan> my reader head is fixed to the body of my machine
[23:57:40] <tjtr33> the distance to the sclae, the paralelism, the height to the tacks
[23:57:41] <zeeshan> the scale looks like its on some fancy mounts
[23:57:43] <furrywolf> loosen screws, run back and forth, tighten somewhere it doesn't rub? :P
[23:57:44] <zeeshan> to allow for heat expansion
[23:58:03] <zeeshan> i dont see how you can align it.
[23:58:12] <tjtr33> ack! no its very fussy. rub? toss the scale if you rub it
