[02:37:14] <Deejay> moin
[06:01:11] <jthornton> morning
[06:01:18] <XXCoder> yo jthornton
[06:01:27] <XXCoder> just ordered green reel :D finally
[06:01:43] <jthornton> glow in the dark green?
[06:01:49] <XXCoder> nah dark green
[06:02:02] <XXCoder> glowy stuff i already have
[06:10:56] <jthornton> I neet to try that PETG I have, I'd like to print a new X thing that holds the hot end
[06:11:07] <XXCoder> petg is awesome.
[06:11:18] <XXCoder> just dont squash ut too much it dont like it
[06:11:42] <jthornton> what do you print it at?
[06:11:55] <XXCoder> hmm a second
[06:12:15] <XXCoder> 240f 86f
[06:12:37] <XXCoder> I didnt dial it very well yet but that works fine.
[06:12:39] <jthornton> f?
[06:12:43] <XXCoder> err c
[06:12:53] <jthornton> lol I thought so
[06:12:58] <jthornton> what print thickness?
[06:13:10] <XXCoder> just add hmm .1? to z offset, if .2 mm layers
[06:14:02] <jthornton> yea, I've been printing the PLA at .2 mm layers
[06:14:30] <XXCoder> petg dont really like being squashed
[06:14:36] <XXCoder> so .1 mm layers is out I think
[06:19:42] <jthornton> found another loose place the lower X rod left hole was oversize so I jammed some paper in there to tighten it up lol prints much better now
[06:20:00] <XXCoder> you killed some more of that wobble?
[06:21:26] <jthornton> yea the print head could move up and down a lot so I kept looking till I found the problem
[06:23:55] <XXCoder> funny bec I can lift mine easily. negative part of anti-wobble addons
[06:46:32] <jthornton> for me it made leveling the bed iffy
[06:50:17] <XXCoder> it made it very hard for me
[06:50:26] <XXCoder> because cant have "tight" when it lifts
[06:50:44] <XXCoder> so I evenually found balance. for now. need to finish inductor so its nonissue afetr that
[06:51:22] <jthornton> have you tested it yet?
[06:51:29] <XXCoder> haven finished wiring
[07:00:24] <andypugh> Eeek! somebody just logged in to my CNC machine and opened a web browser!
[07:00:35] <XXCoder> ow!
[07:00:43] <XXCoder> kill its networking before someone runs your cnc
[07:01:47] <sync_> haha andypugh
[07:02:30] <andypugh> It’s unplugged
[07:02:52] <andypugh> Now to figure out how to block external login completely, i have never used it
[07:03:35] <jthornton> wtf, how did they do that?
[07:03:47] <andypugh> I have no idea
[07:04:10] <XXCoder> port scanner?
[07:04:15] <andypugh> Well, I have some idea, because I can do it myself, but how they got in I don’t know.
[07:04:17] <XXCoder> andy anyone else live your place?
[07:04:32] <andypugh> No, defintely external. And probably watching this.
[07:04:35] <MacGalempsy> XXCoder: I agree that petg is pretty amazing. three prints in a row have gone to completion without a hitch
[07:04:42] <jthornton> did they ssh in?
[07:04:46] <nubcake> morning
[07:05:05] <andypugh> jthornton: At a guess, yes.
[07:05:06] <XXCoder> MacGalempsy: it is. my printer have problems with it though LOL heat creep is BIG problem, as well as first layer problems
[07:05:09] <nubcake> does anyone here use a synology diskstation (raid10 maybe)?
[07:05:46] <MacGalempsy> I was just about to say that the first layer is the only part that has not come out 100%
[07:05:57] <andypugh> The question is, which other machines are they in?
[07:05:58] <jthornton> XXCoder: you need to add a couple of print fans like I did
[07:06:01] <MacGalempsy> but once its down, the rest goes great
[07:06:22] <XXCoder> jt indeed but im stuck on designing a mount for it, since need to add autoleveling postion to it too
[07:06:36] <XXCoder> it need to hold 40 mm fan, 50 mm duct fan, and autolevel inductor sensor
[07:06:36] <MacGalempsy> no fan used here
[07:07:03] <andypugh> Going offline to thoink
[07:07:11] <jthornton> I just hung a couple of 30mm fans on the cold side fan pointing down
[07:07:48] <XXCoder> I have surplus of 50mm fans
[07:07:54] <XXCoder> boyght 5 for few bucks
[07:08:07] <MacGalempsy> XXCoder: what are you using for the bed? Kapton seems to be working well
[07:08:18] <XXCoder> $1 frame glass
[07:09:09] <jthornton> nope they are 40mm fans
[07:09:14] <jthornton> http://gnipsel.com/images/prusa-i3-clone/print-fans-01.jpg
[07:09:37] <XXCoder> fob fans are 40mm too? sure looked smaller
[07:09:52] <MacGalempsy> fan city!
[07:10:23] <MacGalempsy> http://www.thingiverse.com/thing:32173/#files
[07:10:28] <jthornton> hey they work, no heat creep
[07:10:56] <Wolf_> this place linuxprinter this morning?
[07:10:59] <MacGalempsy> what is heat creep?
[07:11:00] <Wolf_> =P
[07:11:40] <jthornton> the part stays soft and starts to warp
[07:12:02] <XXCoder> its called that because heat travels up and stacks up so print gets messed up
[07:12:15] <XXCoder> corners curling up is very typical syntom of that
[07:12:23] <Wolf_> in the print or in the hotend?
[07:12:27] <XXCoder> print
[07:12:27] <MacGalempsy> hmmm. havent had that issue yet with petg, but with ABS it was quite normal
[07:12:35] <jthornton> http://www.thingiverse.com/thing:512338
[07:12:36] <XXCoder> cold end heat creep causes jams
[07:12:59] <Wolf_> abs is just a total pain in the ass to print with
[07:13:04] <XXCoder> thats for real prusa unfortunately
[07:13:08] <XXCoder> rods is aligned
[07:13:22] <MacGalempsy> http://www.thingiverse.com/thing:906917
[07:13:37] <Wolf_> my last pla print warped a little on the corners
[07:13:59] <XXCoder> wolf yea need part cooling
[07:14:23] <MacGalempsy> abs with kapton was way better than hairspray.
[07:14:56] <XXCoder> I dont plan to use hairspray
[07:15:05] <XXCoder> glass and elmer is pretty effective
[07:15:15] <Wolf_> http://i.imgur.com/MnCqYVl.jpg not a small print
[07:15:35] <XXCoder> whats that
[07:16:56] <Wolf_> http://www.thingiverse.com/thing:1666929
[07:17:15] <XXCoder> thats pretty cool
[07:17:40] <jthornton> neet, I need some wrench holders for my tool box
[07:18:24] * Jymmm grabs the crazy glue and helps jthornton
[07:18:45] <archivist> eeerrrrmmm cheaper to get a set of drawers from Aldi/Lidl
[07:19:47] <Jymmm> then those plastic holders you mean?
[07:25:02] <cpresser> i am having trouble with packages from the buildbot "The repository '
http://buildbot.linuxcnc.org jessie Release' is not signed."
[07:25:22] <cpresser> can somebody confirm this or give me som advice
[07:29:49] <jthornton> are you adding a deb line and getting that error from apt or something like that?
[07:30:06] <jthornton> http://www.thingiverse.com/thing:364559
[07:30:25] <XXCoder> fancy
[07:30:26] <cpresser> jthornton: yes. i added the deb line to sources list.
[07:30:32] <cpresser> copied from the buildbot page
[07:31:19] <cpresser> "deb
http://buildbot.linuxcnc.org/ jessie 2.7-sim"
[07:31:27] <MacGalempsy> jthornton: that is pretty neat, just started this
http://www.thingiverse.com/thing:552508
[07:31:52] <XXCoder> fancy
[07:32:00] <XXCoder> wonder how hard it is to clean
[07:32:05] <XXCoder> out of what plastic?
[07:32:13] <MacGalempsy> i'll let you know. petg of course
[07:32:25] <XXCoder> yea good idea, almost cant wash pla
[07:34:17] <jthornton> cpresser: I don't have a jessie install anywhere to test with
[07:38:53] <jthornton> http://www.thingiverse.com/thing:1632847
[07:39:16] <XXCoder> thats decent design
[07:39:23] <XXCoder> too bad real prusa only lol
[07:39:34] <jthornton> yea, doesn't block your view
[07:39:50] <tiwake> jthornton: every time I see thingverse I expect to be reading articles on different parts of the movie The Thing
[07:43:53] <XXCoder> Thing universe - everything you wanna know about The Thing
[07:47:14] <Jymmm> I still think crazy glueing your wrench to the toolbox will hold em for sure =)
[07:47:21] <Jymmm> wrenches*
[07:47:34] <Jymmm> then you can't lose/misplace them ;)
[07:48:13] <gregcnc> sure they'd be IN the toolbox, but where in hell is the tool box?
[07:48:18] <Wolf_> this is why you don’t let amateurs in the shop, any real mechanic would know to weld them in to the drawer
[07:48:42] <Jymmm> gregcnc: on the roof.... DUH
[07:49:19] <Jymmm> Wolf_: but but but...it's a 3d printed toolbox
[07:51:30] <Jymmm> gregcnc: Oh, actually, it's out by the picnic bench...
http://cmzone.vzbqbxhynotw9ion96xv.netdna-cdn.com/wp-content/uploads/2016/03/BBQToolbox1.jpg
[07:52:21] <gregcnc> A toolbox with hamburgers, could come in handy...
[07:52:38] <MacGalempsy> mmmm burgers
[07:54:54] <Jymmm> jthornton: Built in wrench and socket holders
http://agaperiding.org/wp-content/uploads/2014/01/tool-chest.jpg?622897
[07:55:20] <MacGalempsy> Jymmm: which thingiverse item is that?
[07:55:55] <jthornton> I've seen that before
[07:55:58] <Jymmm> MacGalempsy: D) None of the above
[07:58:38] <Jymmm> MacGalempsy: jthornton $800
http://www.strictlytoolboxes.com/extreme-41-portable-workstation-chest.html
[07:59:07] <jthornton> I just saw that
[07:59:23] <MacGalempsy> that is a pretty sweet box.
[07:59:53] <MacGalempsy> you shuld send us each one for a review
[08:00:14] <MacGalempsy> the locking mechanism looks like of flimsy
[08:00:36] <Jymmm> MacGalempsy: Yes, *YOU* should set that up for all of us to eval
[08:00:55] * jthornton doesn't want one
[08:01:19] <MacGalempsy> sorry Jymmm if JT doesnt want one, they arent good for the rest of you
[08:02:36] <MacGalempsy> it is amazing the price range of used boxes on craigslist
[08:02:55] <Jymmm> jthornton: would take one for free
[08:02:58] <MacGalempsy> the same snapon box can vary by $1000 or more
[08:04:00] <archivist> and the damned boxes can never take all your tools
[08:04:43] <MacGalempsy> lol
http://fayar.craigslist.org/zip/5931435089.html
[08:05:26] <Jymmm> It's called 1/2" polycarb
[08:05:32] <MacGalempsy> that kid needs to be woooped
[08:05:51] <MacGalempsy> 2- 60+" tvs broken
[08:06:04] <Jymmm> MacGalempsy: You've never worked with mentally challenged I see
[08:06:36] <MacGalempsy> nope.
[08:09:31] <ToddZ> TVs make poor babysitters.
[08:11:03] <Wolf_> flat screen tv make poor playpen walls
[08:11:13] <Jymmm> archivist: You were saying...
http://www.filarveneto.eu/wp-content/uploads/2014/04/piyanomr2.jpg
[08:12:10] <archivist> seen that pic many times
[08:12:33] <Wolf_> just need right box
http://r3.vehicleservicepros.com/files/base/VSPC/image/2015/09/16x9/640x360/Tommy_Grimes_T_L_Automotive_NC.55f98d952a84f.jpg
[08:13:00] <Jymmm> Wolf_: betcha the snapon toller loves that guy
[08:13:05] <Jymmm> dealer
[08:13:07] <MacGalempsy> thats bigger than my college apartment!
[08:13:15] <archivist> that is more like it!
[08:13:51] <Jymmm> http://r3.vehicleservicepros.com/files/base/VSPC/image/2015/09/16x9/1280x720/Tommy_Grimes_T_L_Automotive_NC.55f98d952a84f.jpg
[08:13:55] <MacGalempsy> is there a matching 4 wheeler to move that thing?
[08:13:58] <archivist> actually it is a cafe/burger bar by the look of it
[08:15:57] <Jymmm> archivist: I think you're right...
http://www.nsfwallet.com/wp-content/uploads/2014/12/Tool-Chest-Mini-Fridge.jpg
[08:16:53] <MacGalempsy> does this seem overpriced?
http://dallas.craigslist.org/ftw/tls/5936776114.html
[08:18:16] <archivist> I would regard it over priced
[08:18:42] * jthornton wonders why it is all apart
[08:18:54] <MacGalempsy> ok. it seemed so, but there is such a lack of used lathes around here
[08:19:18] <archivist> looks like a cleaned up barn find
[08:19:27] <MacGalempsy> are the gears changed out for different threads pitches?
[08:19:35] <archivist> yes
[08:20:04] <archivist> that being the cheap model without gearbox
[08:27:48] <Wolf_> nice, missed a $300 lathe on one of the FB sales groups… Monarch 18.5”x78”…
[08:44:08] <MacGalempsy> Wolf_: thats a pretty big machine, no?
[08:44:35] <Wolf_> 78” between centers, yeah sorta big
[08:45:50] <archivist> too small for a real machine shop amateur size often costs a bit more
[08:46:44] <MacGalempsy> a little too big for the average amateur?
[08:47:47] <Wolf_> over 8 foot long machine
[08:48:00] <archivist> they perceive them to be too large
[08:48:02] <MacGalempsy> at that size, it seems an overhead lift system just to load the workpiece
[08:48:13] <Wolf_> forklift =)
[09:02:11] * JT-Shop thinks it is a good day to cut a hole in the roof of the new shop
[09:02:41] * _methods thinks cutting a hole in a roof is a better way to get rain to show up than washing the car
[09:04:21] <Wolf_> always
[09:36:44] * JT-Shop thinks it's worth $10 for a CPU cooler for this Asus socket 775 MB
[09:51:20] * MacGalempsy thinks there is more to working out than he remembers.
[10:00:43] <lunada> morning
[10:01:53] <MacGalempsy> :) morning
[10:02:17] * archivist points at the clock
[10:02:48] <lunada> so i got my axes tuned fairly well using p,ff1, and ff2. but i do notice a little jitter in the following error. the more p there is, the more of this jitter there is. it doesnt seem like oscillation, and nothing i do seems to get rid of it
[10:03:09] <lunada> it's only during movement
[10:03:23] <MacGalempsy> ballscrews or leadscrews?
[10:03:28] <lunada> ball
[10:03:37] <MacGalempsy> how much error?
[10:03:50] <lunada> .001 tops
[10:03:59] <lunada> probably a little less
[10:04:23] <lunada> the unit is in inches
[10:04:28] <MacGalempsy> that is pretty good. could it be the screws themselves?
[10:04:32] <lunada> should i live with it?
[10:04:50] <lunada> it's possible that the machine is pretty dry
[10:05:07] <lunada> it's in a wood shop so i'm sure that isn't helping with lubrication
[10:05:09] <MacGalempsy> what is the encoder resolution?
[10:05:37] <lunada> 2000ppr, and the scale is 20000
[10:05:47] <MacGalempsy> 1/20000
[10:06:03] <cradek> so 20 counts
[10:06:21] <cradek> have you tried adding a bit of D?
[10:06:22] <MacGalempsy> that seems pretty good for woodwork.
[10:06:34] <lunada> it's a metal working machine
[10:06:45] <lunada> i did try adding d, it made things worse
[10:07:18] <cradek> too much D will make it worse, there's usually a sweet spot where it helps
[10:07:23] <MacGalempsy> what kind of tolerences do you need? that is usually a good factor
[10:08:07] <cradek> does it feel and sound rough?
[10:08:25] <lunada> i can feel it a little bit
[10:09:08] <lunada> i'd like to have the machine as close as possible. .001" is a bit much for feedrates, but i can live with it for rapid
[10:09:24] <lunada> i guess i can check it at slow speed.
[10:09:50] <lunada> i can't tell if it is mechanical or not...
[10:10:13] <cradek> yeah it sounds like something is not yet right
[10:10:19] <lunada> i know the z was hanging up mechanically, but some lube fixed that
[10:11:37] <lunada> the ways were super dry since sawdust seems to absorb it all, but the x axis is pretty well covered
[10:11:59] <MacGalempsy> lunada: tuning seems to be a science unto itself around here. i have these old analog drives and it took a long time before the right numbers were determined
[10:12:32] <cradek> lunada: yikes. if it has a one shot system with metering nozzles, verify each nozzle is working
[10:12:32] <lunada> yea, you're not kidding.
[10:12:34] <MacGalempsy> i still cannot get the a axis to go correctly
[10:12:41] <cradek> they get plugged up really easily
[10:12:59] <MacGalempsy> time for a car...err... lathe cover
[10:14:06] <lunada> cradek: it hasnt been run in the woodshop yet so i dont think it's that.... i think it's more of an issue of it not having been lubed in a while. i guess i need to work on the lube system to get it functional next
[10:14:26] <lunada> lol it's a bit big for a car cover. it's a vmc
[10:14:56] <cradek> they will plug just from sitting, not necessarily contamination
[10:15:08] <cradek> oil is glue if you just wait a while
[10:15:21] <lunada> i'll manually turn it on and see if it comes out
[10:15:50] <MacGalempsy> the grease on the speedo on this 1970 toyota was hard as a rock,
[10:15:50] <lunada> pretty certain it worked a few months ago
[10:19:08] <lunada> i'll play with it a little more, thanks for the tips
[10:19:33] <gregcnc> how?
http://tinyurl.com/gwbn7qk
[10:22:02] <archivist> why!
[10:23:30] <archivist> you can get flexible pcb made, then wrap
[10:23:49] <archivist> but pretty senseless
[10:28:21] <andypugh> Maybe, but I think it looks great
[10:29:00] <Wolf_> costs less then the pen I just ordered a couple days ago...
[10:29:20] <MacGalempsy> ?
[10:29:26] <MacGalempsy> what did you order?
[10:29:33] <Wolf_> well, pencil actually
https://www.indiegogo.com/projects/01-world-s-first-dimensioning-instrument-3d--2#/
[10:29:38] <andypugh> Yes, I am genuinely tempted. But have remembere that I have forgotten how to write.
[10:30:45] <MacGalempsy> I thought you were an AI of the real andypugh
[10:30:57] <MacGalempsy> who died in 1977
[10:31:29] <andypugh> If you believe Facebook I am 100 years old…
[10:31:58] <MacGalempsy> there is no fake news on facebook
[10:32:03] <Jymmm> andypugh: We don't need FB to believe that ;)
[10:33:27] * roycroft continues to shun facebook (and twitter)
[10:35:56] <archivist> I am immune from twatter and fb too
[10:38:36] <andypugh> archivist: don’t do Twitter, but someone sent me this, which I liked:
https://pbs.twimg.com/media/C0cAeMOWQAAvZus.jpg:large
[10:41:39] <gregcnc> duh, i didn't think about flexible pcb
[10:42:42] <archivist> he cocked up and had to miss parts that stopped the wrap :)
[10:43:42] <gregcnc> still, he's probably making a decent penny for his owrk
[10:46:12] <MacGalempsy> is there an indecent penny?
[10:48:17] <roycroft> when it costs more than a penny to make a penny that made penny is indecent
[10:57:29] <MacGalempsy> lol
[10:58:52] <MacGalempsy> can anyone help me figure out which digital servo drive I can use to replace these analog drives? the goal is to just replace the drives, not the motors
[11:00:43] <archivist> that question leaves a lot of guessing needed
[11:01:23] <MacGalempsy> sorry, that is due to my lack of knowledge on such topic
[11:01:46] <MacGalempsy> what is in there now is 90v max, 5A continuous
[11:02:37] <MacGalempsy> the analog drives are setup in torque mode, but will replacing them with velocity drives limit performance?
[11:04:09] * cpresser is currently searching fot 100V 4Amp FullBridges to drive my brushed DC servos
[11:04:44] <MacGalempsy> these are brushed dc servos.
[11:05:17] <MacGalempsy> i am curious to know if there is generic (per say) drive that covers a range of motors and works well with lcnc
[11:06:44] <Wolf_> the AMC drives I have cover a few things
[11:07:15] <MacGalempsy> Wolf_: how was the tuning effort?
[11:08:09] <MacGalempsy> perhaps a call to copely would help come up with a solution
[11:08:43] <Wolf_> BLDC/brushed, 40-190 vdc 25A peak
[11:08:53] <Wolf_> no idea on tuning yet
[11:08:58] <MacGalempsy> $$?
[11:08:59] <Wolf_> not on a machine
[11:09:14] <Wolf_> BE25A20 on ebay
[11:10:33] <Wolf_> that one has encoder inputs as well, which I don’t think you need with 7i77 running them
[11:10:42] <MacGalempsy> do digital drives analyze the motor characteristics then make the settings automatically?
[11:11:01] <Wolf_> derp, not digital driver
[11:15:41] <gregcnc> tuning torque mode isn't hard, but you can't follow velocity mode instructions
[11:20:54] <MacGalempsy> i would love to have someone remote login to my box and teach me. would even compensate for time
[11:22:01] <Wolf_> is the tuning done in lcnc or in the driver?
[11:22:36] <MacGalempsy> all I can do is tune with lcnc. the drive was "extensively tuned" by the factory
[11:23:11] <MacGalempsy> looking through the header, it appears the peak and contuinuous were changed from the normal factory setup
[11:25:03] <MacGalempsy> tuning the x y z with the ziegler-nichols method worked pretty well, but trying that on the A did not produce similar results
[13:01:04] * JT-Shop in his typical fashion makes a cardboard template of the cutout for the stove pipe taking into account the roof pitch
[13:01:43] <SpeedEvil> JT-Shop: are you familiar with project binky?
[13:02:54] <Jymmm> JT-Shop: you using dbl or triple wall pipe?
[13:18:34] <Wolf_> pinky cad
[13:18:40] <Wolf_> binky*
[13:32:52] <JT-Shop> SpeedEvil: yes, I've downloaded most of the videos
[13:33:07] <JT-Shop> 220 221 whatever it takes Jymmm
[14:15:45] <Wolf_> I want to copy the frame table jig thing they have
[14:47:13] <CaptHindsight> if I/m paying for 120/208VAC and I'm only getting 118/207VAC shouldn't I get a discount?
[14:50:37] <skunkworks> Yes!
[14:51:01] <roycroft> except that's not what you're paying for :)
[14:54:10] <CaptHindsight> roycroft: true, they advertise one thing and charge you for another
[14:56:03] <roycroft> what they'll guarantee is that your power will be delivered at 60.0Hz
[14:56:23] <roycroft> at a nominal voltage
[14:56:34] <roycroft> but you pay by the watt
[14:57:14] <CaptHindsight> roycroft: do they really guarantee 60.0Hz +/- 0.1Hz?
[14:57:41] <roycroft> most power companies do
[14:57:43] <roycroft> if not all
[14:58:00] <roycroft> i did some work years ago with a hydro power company
[14:58:10] <roycroft> they were in remote washington state
[14:58:21] <CaptHindsight> I can't find it now but I came across the line frequency of our local co measured over time
[14:58:34] <skunkworks> that is why your plugged in clock always works
[14:58:35] <CaptHindsight> it varied a bit
[14:58:39] <roycroft> had some diversion sluices a couple miles upstream from ther generators
[14:58:41] <skunkworks> (keeps time over the day)
[14:58:54] <roycroft> i was getting the control circuits working for them
[14:59:13] <CaptHindsight> I recall it being by more than 0.1Hz over the day
[14:59:24] <roycroft> when i got things going i asked them to fire up the plant
[14:59:35] <roycroft> to see if there was interference
[14:59:57] <roycroft> the problem was the control circuit cables were buried in the same trench as the transmission cables
[15:00:08] <roycroft> they were supposed to be on the other side of the creeks
[15:00:14] <roycroft> but they were installed wrong
[15:00:15] <roycroft> plus
[15:00:21] <roycroft> the control cables were shielded
[15:00:28] <roycroft> but they came on 1000' spools
[15:00:46] <roycroft> and when they were spliced together the shield was not splied through
[15:01:02] <roycroft> so they were essentiall unshielded cables laying right next to 50kv ac cables
[15:01:26] <roycroft> anyway, i got the control signals working, but wanted to see of that ac voltage would hose things
[15:01:42] <roycroft> it took about 15 minutes to get the generators turned up and tuned
[15:02:02] <roycroft> then they spent about 30 minutes synchronizing the line frequency with the grid
[15:02:09] <roycroft> then they were able to connect to the grid
[15:02:19] <roycroft> it was a really big deal to get that line frequency as exact as possible
[15:02:50] <SpeedEvil> It's quite hard to drive the grid to a different frequecy
[15:03:02] <CaptHindsight> heh
[15:03:14] <roycroft> it gets really messy if you inject power out of phase into the grid
[15:03:37] <CaptHindsight> so if I send power to the grid from my solar battery system I can't make the neighborhood 70Hz?
[15:03:45] * SpeedEvil hums 'smoke gets in your eyes'
[15:04:04] <roycroft> the power police would be dropping bombs on your pv array in an instant if you tried that
[15:04:05] <roycroft> :)
[15:04:56] <CaptHindsight> whats the efficiency of the newer DC to AC injectors for small <20KW systems?
[15:04:57] <skunkworks> nah - your meter would just start spinning a lot faster...
[15:05:07] <SpeedEvil> CaptHindsight: >>90%
[15:05:39] <roycroft> i'm not sure you'd even be able to do it
[15:05:58] <SpeedEvil> Sure you can
[15:06:01] <roycroft> most utilities require a utility owned and maintained interface for injecting into the grid
[15:06:05] <SpeedEvil> you ca buy them off the shelf
[15:06:07] <CaptHindsight> the power co was pretty picky about hooking up systems that would sell power back to the grid
[15:06:17] <CaptHindsight> around here
[15:06:24] <SpeedEvil> Standardisations required vary
[15:06:27] <roycroft> i'd assume that interface would refuse to connect anything it does not like
[15:08:51] <CaptHindsight> Tesla announced some battery system for the home
[15:08:57] <CaptHindsight> ties to solar
[15:10:21] <CaptHindsight> http://www.wholesalesolar.com/9994950/solaredge/inverters/solaredge-se5000a-us-u-inverter $1245 for a grid tied inverter %kw
[15:10:27] <CaptHindsight> 5KW
[15:13:18] <CaptHindsight> are these just switchers with IGBT's?
[15:14:01] <gregcnc> I hope I don't have to pay more since mine hovers over at 252V. A couple weeks ago the stepper drives in my mill and 2 vfd had overvolt errors. Yikes
[15:14:49] <CaptHindsight> gregcnc: do you have 120/240 delta or 120/208 wye there?
[15:15:09] <CaptHindsight> that's really high
[15:15:46] <gregcnc> residential
[15:16:17] <CaptHindsight> so 2-pole, what is it usually at ~208?
[15:16:37] <gregcnc> ~250
[15:17:44] <CaptHindsight> wonder if the transformer for your block has a few windings short on the secondary
[15:18:35] <gregcnc> a bit lower today 246
[15:19:03] <CaptHindsight> are the homes there over 30 years old?
[15:19:23] <gregcnc> ~20
[15:20:25] <CaptHindsight> huh, comed used to use only delta years ago, they switched to wye for residential back in the 70's-80's
[16:28:12] <nikre> what is the proper way of compensating for a not well aligned axis on linuxcnc?
[16:31:27] <Deejay> proper align the axis? ;)
[16:31:52] <XXCoder> why cant it be dialed in
[16:33:17] <cradek> what do you mean aligned?
[16:33:35] <cradek> we have screw compensation
[16:45:38] <Deejay> gn8
[16:47:01] <XXCoder> cradek: THINK that guy means for example Y that isnt perfectly 90 degree to X for example but dunno guy went silent
[16:59:11] <JT-Shop> almost got the flue pipe installed for the wood stove... running out of daylight
[16:59:34] <malcom2073> So, I got one of these:
http://www.shars.com/3-4-x-1-2-shell-mill-arbor and one of these:
http://www.ebay.com/itm/122247128562
[17:00:39] <malcom2073> The bolt on the holder is of a smaller diameter than the tool, am I missing something important here? Do I have to machine a washer of the right size?
[17:00:49] <malcom2073> The bolt is smaller diameter than the shaft of the armor
[17:00:51] <malcom2073> arbor*
[17:03:13] <JT-Shop> missing the washer
[17:03:21] <malcom2073> Lovely.
[17:03:43] <JT-Shop> it's the collar thing around the SHCS
[17:03:55] <malcom2073> https://scontent.fphl2-1.fna.fbcdn.net/v/t1.0-9/15781565_1496948743652835_6649044744799636467_n.jpg?oh=c9a09ff291f0337262ca90c0742b3001&oe=58EE1148
[17:03:55] <malcom2073> https://scontent.fphl2-1.fna.fbcdn.net/v/t1.0-9/15823676_1496948773652832_5397184835793151746_n.jpg?oh=dedba9c86e1dceb94a762bacb36d6906&oe=58F4916F
[17:04:28] <malcom2073> Alright, time to email them
[17:07:15] <roycroft> regarding handling firewood multiple times:
[17:07:22] <roycroft> https://www.youtube.com/watch?v=XasJ6rwWc6U
[17:08:43] <XXCoder> no touchy
[17:08:49] <XXCoder> oops sorry spoilers
[17:13:17] <malcom2073> Alright emailed shars back. There goes tonights plans to make chipsheh
[17:20:28] <nikre> XXCoder, you are right it is not perfectly 90 degree
[17:21:07] <XXCoder> guessed so. only fix is to fix the frame. I had that slant pribnt problem with Z axis being off. fixed it
[17:22:04] <nikre> my router is not standard, it is wooden :)
[17:22:19] <XXCoder> square it up
[17:22:58] <nikre> there is inaccuracies everywhere. i wondered if linuxcnc has a means to deal with these
[17:23:08] <nikre> by taking sample probings etc
[17:23:37] <XXCoder> theres comp for many stuff but not being out of square so far I know.
[17:23:43] <roycroft> get out your chip knife and whittle it flat
[17:25:31] <nikre> so i guess there is no suggested way to modify gcode
[17:25:58] <XXCoder> nope its case of having to fix your machine
[17:28:24] <roycroft> if your bed is not flat you can probe it and compensate
[17:28:38] <roycroft> but if the frame is out of square i don't know that there's an easy way to work around that
[17:44:15] <gregcnc> malcom20736 what are you going to cut with that setup?
[17:44:40] <pcw_mesa> you could use skew kinematics but whether its worth the trouble IDK
[17:47:03] <andypugh> malcom2073: I think you have the wrong shank for that tool.
[17:47:31] <malcom2073> andypugh: yeah?
[17:47:44] <andypugh> Shell mill albors have a couple of drive dogs, and shell mills have a couple of slots.
[17:48:09] <malcom2073> Hmm, this one indeed does not
[17:48:12] <gregcnc> i was going to say, but assumed he knew and was cobbling stuff
[17:48:20] <malcom2073> I haven't a clue what I'm doing
[17:48:30] <gregcnc> what do you plan to cut?
[17:48:36] <malcom2073> a rounded slot in aluminum
[17:48:56] <andypugh> http://www.ebay.com/itm/3-90-degree-indexable-face-shell-mill-face-milling-cutter-TPG322-506-FMT-3-new-/181136203890?hash=item2a2c8f2072:g:y5sAAOSwo4pYRt2S in the second photo you can see the slots.
[17:49:23] <malcom2073> andypugh: Listing removed or not available
[17:49:29] <malcom2073> But I know the slots you're talking about
[17:49:42] <andypugh> malcom2073: Item 181136203890
[17:49:55] <malcom2073> Ok worked that time, odd
[17:49:59] <malcom2073> Yeah
[17:50:34] <malcom2073> Like I said, haven't a clue what I'm doing, just wanted toavoid spending $200 on a tool for this
[17:51:42] <gregcnc> ball mill not an option?
[17:52:27] <malcom2073> gregcnc: It is, but that takes a lot of passes and doesn't leave a very desirable finish (low cut speed at the center of the ball)
[17:53:34] <sync_> tilt the head
[17:53:40] <malcom2073> sync_: head doesn't tilt
[17:53:50] <sync_> tilt your work
[17:53:53] <malcom2073> Figured this sort of cutter would make cutting 30 of these slots a lot quicker heh
[17:54:05] <gregcnc> is it a large mill?
[17:54:09] <malcom2073> gregcnc: yes
[17:54:15] <malcom2073> sync_: Can't, I need an exact half circle
[17:54:26] <malcom2073> not shallower
[17:54:37] <sync_> you'll get an exact half circle if you interpolate the slope
[17:55:31] <malcom2073> Oh you mean tilting that way
[17:55:32] <andypugh> I think that cutter is for a spindle moulder. I don’t actually know how those hold their cutters.
[17:55:33] <Kevin`> XXCoder, roycroft it's possible to compensate for out-of-square with linuxcnc but it's definitely easier to not have to
[17:55:34] <sync_> hmm
[17:55:59] <sync_> yeah andypugh, it is not made for a milling arbor
[17:56:10] <sync_> but I guess malcom2073 could just machine out a washer and make it work
[17:56:11] <Kevin`> XXCoder:
http://linuxcnc.org/docs/2.4/html/motion_kinematics.html
[17:56:25] <malcom2073> Well lesson learned, ask here before buying shit :-P
[17:56:54] <JT-Shop2> finally got the flue pipe up, just need to seal and screw down the high temperature boot tomorrow and that project is done
[17:57:16] <malcom2073> I'll probably machine a washer, and cut slots in the ring of the tool to let it sit down on the tabs
[18:00:14] <Kevin`> not wanting to grind a tool, i'd probably try a washer with slots. then it would spin and I would do that instead. but the tool is designed to work without them somehow
[18:00:48] <sync_> well it is made for wood routers
[18:00:50] <gregcnc> it's designed for wood at high RPM low torque, no slots required
[18:01:06] <malcom2073> So, is there anywhere toget a tool that does metal, for less than $100?
[18:01:12] <malcom2073> assuming I can't actually make this work
[18:01:12] <gregcnc> www.ebay.com/itm/111176660609
[18:01:35] <malcom2073> Should've askedhere first haha. Then I need an arbor for that
[18:01:52] <gregcnc> http://www.ebay.com/itm/311301874319
[18:02:55] <malcom2073> Hmm, that may be long enough...
[18:03:56] <malcom2073> Fack it's gonna have to wait another month unless shars will give me my money back heh. I'll ask again then.
[18:06:06] <andypugh> My “thing” is looking surprisingly like the CAD model:
https://goo.gl/photos/3yLbu8sZbiDuu2Lx5
[18:06:35] <malcom2073> Cool looking widget!
[18:07:25] <andypugh> Perhaps if I post it to Clickspring he will polish it for me?
[18:07:54] <malcom2073> That does look awfully clickspring, minus the shiny
[18:15:50] <JT-Shop2> interesting thing andypugh what is it?
[18:16:28] <andypugh> A differential
[18:16:42] <JT-Shop2> cool, what for?
[18:16:50] <andypugh> A clock/
[18:17:08] <JT-Shop2> so there is a third gear hidden from view?
[18:17:08] <andypugh> I realise that most clocks get by without a differential :;)
[18:17:19] <andypugh> It’s only partly done
[18:17:33] <JT-Shop2> pretty cool
[18:18:21] <andypugh> I didn’t make enough pinion material all those years ago, so need to make a bunch more gears.
[18:20:13] <andypugh> Also, annoyingly, a long time ago I modelled the gear centres wrong, so the holes are in the wrong place. But as I need to make some more gears anyway I will make some with profile shift to rescue the situation.
[18:28:17] <Tom_L> andypugh machined from a solid chunk of brass?
[18:29:47] <andypugh> Yes.
[18:29:57] <andypugh> But it’s in three sections.
[18:30:19] <Tom_L> yeah but still... was that hard to come by locally?
[18:30:25] <andypugh> eBay
[18:30:27] <Tom_L> pretty hefty piece
[18:30:31] <andypugh> £56
[18:30:55] <andypugh> (but I would have had enough for two with fewer cock-ups)
[18:30:58] <cradek> wow
[18:33:28] <Tom_L> melt the chips and you may have enough for another one :D
[18:33:46] <andypugh> I am keeping the chips, that’s for sure.
[18:34:39] <andypugh> I designed this years ago, and decided I needed a CNC to make it. The rest is history.
[19:39:00] <Frank_10> hi
