#linuxcnc | Logs for 2015-05-23

[00:01:59] <furrywolf> based on the tests I've done, and the fact that the inverter has bad written on it, I'm going to conclude it's a bad inverter... I've checked all the testable inputs/outputs to it and they look good...
[00:03:51] <furrywolf> it's got ac voltage on all six stator outputs, but shows no sign of life.
[00:34:38] <furrywolf> all the terminal resistance measurements given in the service manual are good, showing there's no blown diodes or shorted fets... too bad it's potted! I hate potting!
[00:57:56] <zeeshan|2> fuck just blew up 4 flute
[00:58:07] <zeeshan|2> 1/2" carbide tialn yg1 end mill on stainless
[00:58:32] <zeeshan|2> i must be doign something wrong :/
[00:58:48] <zeeshan|2> ive got it set to 120 sfm, .003 ipr
[00:58:51] <zeeshan|2> is that too slow?
[01:02:56] <t12> howd it blow up
[01:03:00] <t12> whats the chip
[01:03:08] <zeeshan|2> i was helicaling down
[01:03:14] <zeeshan|2> and it went cherry red
[01:03:16] <zeeshan|2> and blew up
[01:03:25] <zeeshan|2> part way during the helical
[01:04:09] <t12> bottom cutter chip size and side chip size?
[01:04:21] <zeeshan|2> i dont know
[01:04:27] <zeeshan|2> it was helicalling down..
[01:04:29] <zeeshan|2> :P
[01:05:18] <t12> toolpath gen?
[01:05:31] <zeeshan|2> like it goes helical down
[01:05:35] <zeeshan|2> to .275 doc
[01:05:41] <zeeshan|2> and its supposed to do a .1 step over
[01:05:46] <zeeshan|2> (circle milling)
[01:06:46] <t12> any clues in the milled part?
[01:06:50] <zeeshan|2> no
[01:06:55] <zeeshan|2> im gonna try slower feed :/
[01:07:00] <zeeshan|2> and 80sfm
[01:07:11] <t12> coolant?
[01:07:15] <zeeshan|2> no coolant
[01:07:20] <zeeshan|2> arent supposed to use it... apparently
[01:08:53] <t12> i guess i'd just try to get to minimum reasonable chip load on bottom and side and work from there
[01:15:50] <XXCoder> zeeshan|2: heh almost did same thing to small 1" facemill yeserday
[01:16:07] <XXCoder> it went cherry red. I ran way too many parts on those teeth
[01:20:27] <t12> .003ipr, 4 tooth = .00075 chip?
[01:21:56] <t12> too small a chip and it may rub and work harden
[01:22:59] <XXCoder> yeah used tool hardening before
[01:23:06] <XXCoder> it was so slow.
[01:29:43] <XXCoder> think it was 0.5 ipm
[01:43:11] <zeeshan|2> i meant to say .003 ipt
[01:43:27] <zeeshan|2> seems like slowing it down to .0015
[01:43:30] <zeeshan|2> is making it cut now
[01:43:42] <XXCoder> ipt?
[01:44:08] <XXCoder> inches per t?
[01:48:49] <zeeshan|2> yes
[01:48:55] <XXCoder> whats t?
[01:48:59] <zeeshan|2> tooth
[01:49:03] <XXCoder> ahh
[01:49:23] <XXCoder> so tooth hits material each .0015?
[01:49:31] <zeeshan|2> kind of
[01:49:37] <zeeshan|2> each tooth removes .0015" of material
[01:51:24] <XXCoder> interesting
[02:06:48] <Deejay> moin
[02:06:52] <XXCoder> no
[02:21:21] <witnit> mojn!
[02:21:48] <XXCoder> mjolnir
[03:10:30] <archivist> hmm interesting comment on the net Just as a datum, the Bently Nevada eddy-current non-contact proximity probes and their signal conditioning boxes (proximitors), give a handy 200mV/Thou reading and have been an industry standard for vibration and position measurement in rotating machines for best part of 50 years.
[03:12:23] <archivist> from http://www.practicalmachinist.com/vb/machine-reconditioning-scraping-inspection/building-differential-electronic-levels-291287/index2.html
[03:16:43] <XXCoder> looking
[03:17:35] <XXCoder> sensive angle detect eh
[03:19:33] <MrSunshine> hmm ... damn cant let this go .. what do you think about making long plinths (is that the name .. concrete thingies in the ground) at the foot locations of the cnc machine .. to make it free floating from the floor in the workshop ..
[03:19:43] <MrSunshine> atm it moves around with the house/floor as things move in there
[03:20:08] <archivist> looks like the next level up from bubble levels, found the technology in a book I was reading yesterday
[03:20:11] <XXCoder> its not heavy enough
[03:20:18] <MrSunshine> an earth drill .. open up the floor some and drill deep holes, fill with concrete and rebar and place machine on it =)
[03:20:22] <XXCoder> in least for movements it does
[03:20:57] <XXCoder> I remember reading about one guy filling voids in his machine with epoxy granite so its heavy enough to not move
[03:21:37] <archivist> bolt it to floor
[03:24:01] <MrSunshine> the floor is wood ... it moves when i walk on it
[03:24:18] <MrSunshine> and that puts twist etc in the machine as its not made out of cast iron :P
[03:24:53] <MrSunshine> and moves with seasons
[03:24:54] <archivist> machine twist is a design not material problem :)
[03:25:14] <MrSunshine> the floor that is .. the whole workshop moves up and down and twists etc with seasonsal changes
[03:25:45] <archivist> stiffen the machine a lot
[03:26:11] <archivist> so floor errors dont transfer to working plane
[03:26:50] <MrSunshine> or .. drill 4 holes in the ground and make the machine floating in respect to the workshop .. and get a quite stirdy foundation at the same time .. ? :P
[03:27:39] <archivist> you still would have spring legs probably
[03:27:56] <XXCoder> add pads of rubber that doesnt bounce
[03:28:01] <XXCoder> less vibration
[03:28:03] <archivist> which is the cheaper and better fix :)
[03:28:54] <XXCoder> is there any instructions online on making cnc machine work?
[03:29:03] <XXCoder> I has this model
[03:29:11] <XXCoder> http://www.aliexpress.com/item/Wood-Lathe-3040-Cnc-Router-Milling-Machine-with-43mm-bracket-Mechanical-Kit-Aluminium-Alloy-Frame/32279070195.html
[03:29:52] <archivist> ew what a description! wood lathe...not
[03:30:01] <MrSunshine> haha
[03:30:12] <XXCoder> I know but its cheap
[03:30:24] <XXCoder> it looks great but no instructions
[03:30:38] <XXCoder> im not too mechinically skilled lol
[03:31:22] <archivist> just look at other peoples retrofits and it should become obvious
[03:31:47] <MrSunshine> that is just the mechanical part right ?
[03:31:47] <XXCoder> http://hackaday.com/2014/02/15/chinese-3020-cnc-machine-gets-some-upgrades/
[03:32:00] <XXCoder> MrSunshine: yeah I has controller and motors
[03:32:26] <MrSunshine> (without stepper motor & spindle motor & control box & cable chain carrier)
[03:32:41] <MrSunshine> well if you dont know something .. learn =)
[03:32:52] <XXCoder> yeah just has some bolts I has no idea what for
[03:33:04] <XXCoder> and metal parts I see nowhere to put on
[03:33:21] <MrSunshine> haha =)
[03:33:28] <XXCoder> gonna figure how to put limits on too
[03:34:00] <archivist> make a website with your pictures and parts, we cannot guess what they are
[03:38:32] <XXCoder> archivist: already sent link
[03:38:54] <XXCoder> though its late (1 am so I will take pics later
[03:45:17] <XXCoder> ohh found it
[03:48:05] <XXCoder> not quite detailed enough
[04:55:13] <dutchfish> good morning, does anyone know how to to do spiral circular pockets in gcode, like with an end mill 3.2mm making 6mm round pockets in linuxcnc?
[04:56:01] <XXCoder> wild guess is series of larger arcs till it gets near final size then do a while circle
[04:56:05] <dutchfish> or is there any py tool to make them?
[04:56:06] <XXCoder> really dunno
[04:56:29] <dutchfish> no i meant spiraling down
[04:56:36] <XXCoder> oh
[04:56:53] <dutchfish> instead of plunge, circle, plunge
[04:57:31] <XXCoder> http://www.cnczone.com/forums/g-code-programing/63083-downward-spiral-cut-movement.html
[04:57:33] <dutchfish> is it just arc-ing with a z-shift?
[04:57:53] <XXCoder> apparently noy
[04:57:56] <XXCoder> not
[04:58:00] <dutchfish> XXCoder++
[04:58:15] <dutchfish> XXCoder, its in there, thanks!
[04:58:18] <XXCoder> g91 isnt implemented on all machines apparently too easy enough to test though!
[04:58:31] <dutchfish> oh, :(
[04:58:32] <XXCoder> np man
[04:58:46] <XXCoder> just air cut test see how it goes
[04:58:53] <dutchfish> yup
[05:00:12] <dutchfish> http://linuxcnc.org/docs/html/gcode/gcode.html#sec:G90-G91
[05:00:23] <XXCoder> doh
[05:00:32] <XXCoder> yeah gonna refresh my memory on g codes
[05:01:08] <dutchfish> XXCoder, is it possible to extend if a G code is not in? is there a doc about extending the G codes?
[05:01:23] <XXCoder> unfortunately im very much a begineer too
[05:01:30] <XXCoder> I do know some stuff is extendable
[05:01:39] <XXCoder> but to what scope and how I has no idea
[05:01:43] <dutchfish> XXCoder, ah ok, fair enough. But thanks anyway!
[05:01:47] <XXCoder> np
[05:02:10] <XXCoder> I know machines I use at work can be set so table goes to specific spot during tool change so tools dont impact work part
[05:02:14] <dutchfish> XXCoder, at least i got some new ideas from your hints
[05:02:49] <dutchfish> XXCoder, that would be a nice options, absolutely
[05:03:11] <dutchfish> XXCoder, as of now, i manually jog to a safe spot
[05:03:32] <dutchfish> XXCoder, but that is tedious
[05:03:33] <XXCoder> maybe check your machine see if it can have gcode attached to event like tool change
[05:03:49] <dutchfish> XXCoder, it can, i build my own
[05:03:54] <XXCoder> cool
[05:04:02] <XXCoder> gonna build my cnc router lol
[05:04:08] <dutchfish> nice
[05:04:13] <XXCoder> I wanna have fun with my own projects at home
[05:04:17] <dutchfish> i am new as well to all this, btw
[05:04:30] <XXCoder> its small one but sould be enough to see if I like having it as hobby
[05:04:34] <XXCoder> if so I want larger one
[05:21:46] <dutchfish> XXCoder, this is were i am now (just made this pic) http://www.yellowsource.org/images/cnc_bootstrap_part3.jpg
[05:22:04] <XXCoder> thats awesome
[05:22:11] <XXCoder> mines http://www.aliexpress.com/item/Wood-Lathe-3040-Cnc-Router-Milling-Machine-with-43mm-bracket-Mechanical-Kit-Aluminium-Alloy-Frame/32279070195.html
[05:22:15] <XXCoder> but unassembled lol
[05:22:52] <XXCoder> need to fix some stuff like motor mounts so it can sit properly with screw on way, then figure how to add limit switches
[05:24:16] <dutchfish> XXCoder, doesnt import duties kill the fun?
[05:24:24] <XXCoder> usa has no import
[05:24:27] <XXCoder> duty]
[05:24:36] <XXCoder> unless youre big business. im not so yea lol
[05:25:11] <dutchfish> dugh, thats awsome, over here it goes almost half way up in price, not even counting shipping costs
[05:26:40] <dutchfish> XXCoder, for all the stuff no the picture i am roughly at 600 euro's or so, and most of the frame is scrap pieces collected with containerdiving
[05:26:46] <dutchfish> s/no/on
[05:27:08] <XXCoder> heh no such thing as good machinist scrap around here
[05:27:22] <XXCoder> hell I have hard time sourcing local machinist stuff
[05:27:29] <dutchfish> XXCoder, well all the alu parts i got for free like that (see pic)
[05:27:38] <XXCoder> damn
[05:27:55] <dutchfish> XXCoder, but you dont have import duties ;)
[05:28:04] <XXCoder> yeah that helps
[05:28:09] <XXCoder> shipping still bit high
[05:28:24] <XXCoder> $166 bucks for that frame
[05:28:29] <dutchfish> a bit?? its a small fortune to ship it
[05:28:37] <XXCoder> yeah
[05:29:36] <dutchfish> XXCoder, the 3 actuators i got for a reasenable price, that made my jumpstart
[05:30:02] <dutchfish> XXCoder, the z-axis one has 2 linear blocks
[05:30:29] <XXCoder> dremel is okay for that
[05:30:36] <XXCoder> I plan to use edge router
[05:30:38] <dutchfish> XXCoder, if not for the actuators, i prolly would have walked the same route as you
[05:30:46] <XXCoder> larger but my cnc router frame can hold it
[05:31:03] <dutchfish> XXCoder, i ordered a Siemens BLDC with controller, but shipping time is 8 weeks
[05:31:16] <dutchfish> XXCoder, 2.2KW watercooled
[05:31:21] <XXCoder> just need to fgure how to hold my edge router lol
[05:31:42] <dutchfish> ? rephrase
[05:31:45] <XXCoder> or if my budget is fine just go to spidle lol (my controller dont have a way to control spidle though
[05:32:00] <dutchfish> ah ic
[05:32:20] <XXCoder> well the holder dont fit my edge router so I gonna make new holder
[05:32:22] <dutchfish> the Siemens one has variable control
[05:32:40] <dutchfish> XXCoder, make your own?
[05:32:47] <XXCoder> yeah plan to
[05:32:52] <dutchfish> great
[05:33:03] <XXCoder> im not very good but table saw and drill with large bore should do it
[05:33:57] <dutchfish> XXCoder, i am bootstrapping with would and replace them with cnc-ed parts along the road, in the end when reproduceability and accuratesse is good enough in alu parts
[05:34:03] <dutchfish> s/would/wood
[05:34:17] <XXCoder> yeah that was my orginial plan
[05:34:23] <dutchfish> XXCoder, for that i need the Siemens
[05:34:29] <XXCoder> make rough cnc then make cnc parts with it
[05:34:32] <XXCoder> then build better cnc
[05:34:34] <dutchfish> bingo
[05:34:55] <dutchfish> and take your time to find great deals
[05:35:02] <dutchfish> on rough materials
[05:35:18] <XXCoder> doubt my router will be able to cut alum
[05:35:23] <dutchfish> there are nice things out there if you look really for it
[05:35:24] <XXCoder> unless slow
[05:36:17] <dutchfish> XXCoder, why not? its not that hard if you respect feed rate calculations versus spindle speed and use the right mill bit for the job
[05:36:40] <XXCoder> edge router unfortunately bottoms out on rpm at 8k rpm
[05:36:41] <dutchfish> XXCoder, it can be slow, but i go for accurate more then speed
[05:36:47] <XXCoder> max 32k and slowest 8k
[05:37:06] <dutchfish> thats a tit high, indeed
[05:37:32] <XXCoder> yeah. no worries though, since alum is minor side to plan, I plan to work mostly with wood.
[05:37:43] <dutchfish> the dremel does a pix poor job on that as well
[05:37:54] <dutchfish> ok
[05:38:25] <dutchfish> i tried ceramics this week, it worked but the results are poor
[05:38:25] <XXCoder> might do thin sheets of alum for some decoation fun though
[05:38:34] <XXCoder> and plastic or glass engraving
[05:38:39] <dutchfish> right
[05:39:27] <dutchfish> plexi is on my list as well as soon as i have a stable frame done and the Siemens is in
[05:40:16] <dutchfish> point contact welding is on m list as well
[05:40:25] <dutchfish> s/m/my
[05:40:27] <XXCoder> cool
[05:40:35] <dutchfish> micro welding
[05:41:13] <dutchfish> and solder paste aplication
[05:41:20] <dutchfish> for the pcb's
[05:41:28] <XXCoder> can do pretty lot with a cnc eh
[05:41:36] <dutchfish> ehe, yup
[05:42:00] * dutchfish hates manually applying solder paste so much ....
[05:42:08] <XXCoder> lol
[05:42:25] <dutchfish> XXCoder, i am to old for that soon anyway
[05:42:41] <XXCoder> why?
[05:42:54] <dutchfish> XXCoder, vision and a steady hand ;)
[05:42:59] <XXCoder> lol yeah
[05:43:43] <dutchfish> XXCoder, right now i am using dentists binoculars for that (dont laugh)
[05:43:59] <XXCoder> well whatever helps eh
[05:44:04] <dutchfish> it works
[05:44:15] <XXCoder> so whats your plan for future job
[05:44:19] <dutchfish> but it gets me dizzy each and every time
[05:44:44] <dutchfish> XXCoder, rf enclosures mostly for my radio hobby and pcb's
[05:45:02] <dutchfish> XXCoder, see my other pics on that link
[05:45:22] <XXCoder> not too sure myself, I do like cnc machinist job but 10 hours of standing for 4 days a week isnt helping my back
[05:45:33] <dutchfish> nope
[05:45:33] <XXCoder> my back didnt quite grow correctly so yeah
[05:45:40] <dutchfish> <-- same
[05:45:54] <dutchfish> mine is in an s-shape
[05:46:14] <XXCoder> s shape is natural, unless its "over extended
[05:46:29] <dutchfish> XXCoder, but mine is that on the wrong axis
[05:46:44] <XXCoder> in my case lower back is forward too much as well as bit weaker bones
[05:46:51] <XXCoder> so my backs like 80- year old man back
[05:46:54] <dutchfish> ah
[05:47:04] <XXCoder> have arthitis for last 10 years
[05:47:09] <XXCoder> fun
[05:47:13] <dutchfish> scoliosis is the correct name
[05:47:20] <XXCoder> though yours sideways s I bet is much worse
[05:47:31] <dutchfish> yup
[05:48:10] <dutchfish> XXCoder, i can do everything, but i got excausted pretty quickly
[05:48:23] <dutchfish> thats all
[05:48:32] <XXCoder> I just wish my back was sole problem
[05:48:40] <XXCoder> I have long list of fun problems lol
[05:48:53] * dutchfish shakes hand with XXCoder
[05:49:53] <dutchfish> sometimes i have vivid dreams cnc-ing my own body parts, but that is not real for the next decade i gues
[05:50:16] <XXCoder> I wouldnt bother with that. just transfer my brain to new body built
[05:50:22] <dutchfish> or 3d printing
[05:50:39] <dutchfish> that is even harder to do
[05:50:55] <XXCoder> yeah likely ill die before its possible lol
[05:51:13] <dutchfish> who knows
[05:51:26] <XXCoder> yeah
[05:52:15] <dutchfish> XXCoder, how far are you with the build of that cnc?
[05:52:44] <XXCoder> it shipped to me with bottom and gantry assembled
[05:52:55] <XXCoder> need to get that together which is easy part
[05:53:00] <XXCoder> gonna figure few other stuff
[05:53:08] <XXCoder> like how to attach limit switches
[05:53:10] <dutchfish> XXCoder, make some pics, that would be nice
[05:53:40] <XXCoder> ok
[05:54:44] <dutchfish> not only for me, but there is a miriad of people out there, to get some unbiased representation on pictures
[05:55:49] <XXCoder> yeah need to get my lazy ass up lol
[05:55:57] <dutchfish> ehe
[05:56:22] <dutchfish> XXCoder, above all, have fun! chao
[05:56:29] <XXCoder> later have fun
[08:53:11] <SpeedEvil> http://images-cdn.9gag.com/photo/aWW3pb6_700b.jpg (sorta-nsfwish)
[08:54:24] <Tom_itx> dutchfish, look at helix for a circular plunge
[08:54:34] <Tom_itx> http://linuxcnc.org/docs/2.7/html/gcode/gcode.html#sec:G2-G3-Arc
[08:55:36] <Tom_itx> add Z & P to your normal arc i think
[08:56:30] <furrywolf> SpeedEvil: and, of course, they have stupidly oversized breasts.
[09:16:47] <furrywolf> any suggestions for a search engine that actually tries to remove spam from their search results?
[09:17:53] <furrywolf> I'm trying to find a service manual for the eu3000is generators, and finding nothing but spam. little pdf files full of ads for non-existant other pdf files...
[09:19:02] <pcw_home> welcome to the internet!
[09:20:54] <furrywolf> how do these people even benefit from these files? it's not like they're getting paid per view like an ad...
[09:22:13] <SpeedEvil> they are - perhaps indirectly
[09:22:41] <SpeedEvil> for example, many of these spam content sites are copyright violation vehicles
[09:23:08] <furrywolf> no, they're not - as far as I can tell, there's no actual content on them. lol
[09:23:09] <SpeedEvil> they then host the content on 'unrelated' server sites that need some sort of login, either ad-funded, or directly paid
[09:24:19] <furrywolf> if I have to spend $40 on a manual for a part of my $50 pile of generators, I'll a) be rather annoyed, and b) build a book scanner.
[09:24:40] <SpeedEvil> the first one for example was a link to
[09:24:41] <SpeedEvil> http://www.urbooklibrary.com/signup?b=1&ad_domain=ads.ad-center.com&ad_path=/smart_ad/display&ref=5029866&q=eu3000is%20service%20manual&sid=16&bt=1432389735674&bh=1671921682
[09:24:57] <SpeedEvil> which says I need to make a free account
[09:25:55] <SpeedEvil> Links in PDF are used to obscure the links from search engines and content owners
[09:28:40] <furrywolf> if I do buy one, I'm definitely going to scan it to fix this problem for the next person needing one.
[09:30:05] <archivist> furrywolf, I supply manual scans but no adverts involved :)
[09:30:26] <archivist> and I am search engine friendly
[09:30:44] <furrywolf> archivist: do you have a service manual for a honda eu3000is?
[09:30:58] <archivist> nope :(
[09:31:38] <archivist> bugger all honda http://www.collection.archivist.info/searchv13.php?searchstr=honda
[09:31:53] <furrywolf> http://www.service-shop-repair-manual.com/honda-eu3000is-eu2600i-generator-part-61zt700-e4-61zt700y-61zt700z-61zt700x-fourth-edition-service-shop-repair-manual/ that seems very likely to steal my credit card info. lol
[09:32:28] <furrywolf> they're claiming to be selling genuine honda paper manuals for $5. methinks not.
[09:32:31] <archivist> looks like a photocopy
[09:33:05] <archivist> actually the colour would say not a copy but the real thing
[09:33:12] <furrywolf> it has red on top, so it's a fancy color photocopy if it is...
[09:33:29] <furrywolf> my suspicion is the site doesn't sell manuals, just take money.
[09:33:38] <furrywolf> too good to be true, etc.
[09:35:11] <archivist> use paypal and and see
[09:35:50] <furrywolf> http://www.m109riders.com/forums/showthread.php?t=247514 although that suggests otherwise
[09:36:10] <furrywolf> It is a VERY high quality copy, put into a high grade executive clear folder. Pictures, diagrams, photos are all crystal clear. It is all B&W. The copyright page has conveniently been left out.
[09:38:30] <archivist> at 5$ it is still cheap
[09:38:47] <furrywolf> I want a PDF at $0. :)
[09:38:54] * furrywolf doesn't need a paper version
[09:39:13] <archivist> dont be stingy, the effort scanning the stuff is hard
[09:40:10] <furrywolf> I guess today I'll try firing up the one with the cracked block... a good glob of silicone should confirm that's the only problem with it.
[09:40:16] <archivist> and some companies actually give permission for the copying services
[09:41:26] <archivist> best request I got was from a designer of a bit of kit, he didnt keep a copy himself
[09:41:52] <SpeedEvil> It should be illegal to sell equipment without full service manuals.
[09:42:03] <SpeedEvil> If you provide the service manuals to anyone ever.
[09:42:14] <SpeedEvil> (and I'm weak on if that qualification should be there)
[09:42:31] <archivist> I agree, but the info often gets lost even if it was supplied
[09:43:08] <SpeedEvil> ^and the supplied info must be with a licence supporting unaltered redistribution
[09:43:16] <furrywolf> I asked fluke for a manual for my ancient multimeter. they said they didn't have one, and anyone who'd ever seen one was dead, but they'd see what they could do. two weeks later they contacted me again, saying they'd purchased the manual, scanned it, and here was the pdf. fluke > honda. heh.
[09:43:29] <SpeedEvil> hah
[09:43:58] <SpeedEvil> I think honda acttially do sell them to dealers though
[09:44:05] <furrywolf> well, they didn't say dead, just words to the effect of "no longer working here".
[09:44:10] <archivist> fluke, tek HP and philips are all nice about out of support docs
[09:44:24] <furrywolf> yes, honda does sell them to the dealer, and there's lots of places online selling new genuine honda manuals... for more than I paid for the stack of generators.
[09:44:45] <furrywolf> archivist: I was impressed that they actually went out and purchased the service manual and scanned it for me.
[09:45:15] <furrywolf> I got ~9 generators for $50 - I don't want to spend $50 on a manual for just 3 of them. lol
[09:45:16] <archivist> furrywolf, I think they know it looks bad when they lost their own docs :)
[09:45:42] <furrywolf> thanks to their manual, I was able to make my old multimeter work again, nixies and all. :)
[09:45:56] <archivist> many just sweep old shelf content to /dev/bin
[09:46:38] <archivist> I actually have a few fluke http://www.collection.archivist.info/searchv13.php?searchstr=fluke
[09:46:52] <furrywolf> like old films and tv shows... "oh, we won't need this again, let's just toss it..." now people paying millions for copies found in old theaters etc. heh.
[09:47:03] <furrywolf> fluke has since put all the service manuals they have on their website
[09:47:43] <furrywolf> I've found two forum posts where people purchased manuals from that site and received acceptable photocopies.
[09:48:30] <furrywolf> if I can't find a pdf, I might have to do that... $5 is a lot better than $40...
[09:48:56] <archivist> I get really annoyed/pissed off when I scan something and dont get a thanks or donation
[09:49:24] <furrywolf> and then I'll scan it and stuff it on my webhost somewhere, so other people can fix their own generators.
[09:50:37] <furrywolf> I bought a collection of antique edison battery manuals that I want to scan too... should build a half-assed plywood+digital camera book scanner one of these days.
[09:52:01] <furrywolf> complete specs, manintenance, etc for batteries, cap lamps, etc.
[09:52:14] <archivist> just have your catalogue online, get donations for the scans, no need to scan till you get a request, less work
[09:52:49] <furrywolf> "Color cover with clear plastic overlay. The rest of the manual is black and white. The print is very clear, pictures are ok. " another forum post where someone ordered from that site and received what sounds like an acceptable copy...
[09:52:52] <archivist> about 30% or better make reasonable donations
[09:53:21] <furrywolf> "on some pages the print seems to be cut short (as if the copy page was not sitting in the machine square)"
[09:53:43] <furrywolf> "Got mine today. It seems ok but it is clearly a cold cut ripoff of the factory manual. Sorry it's not an infringement, it is stealing. I need to take a shower now. " lol
[09:54:49] <furrywolf> donations requires setting up a way to accept money, which seems like way too much work for something I'd be doing to help others.
[09:55:26] <archivist> trivial if you have a paypal account
[09:55:34] <archivist> nothing to set up
[09:56:12] <furrywolf> I had one for over a decade. it got closed because I refused to send them a copy of my driver's license, bank statement, utility bill, and social security card.
[09:59:04] <furrywolf> well, it's not closed - it still exists - it just is disabled so I can't actually use it for anything.
[10:00:29] <furrywolf> http://www.service-shop-repair-manual.com/save-even-more-money-used-like-new-manuals/ LOL! after they scan it, they then sell the originals. :P
[10:18:07] * MattyMatt sets up ReceivePal, the payment service that favours the recipient
[10:18:40] <MattyMatt> any gyp and I'll take another ÂŁ5 "donation"
[10:22:32] <CaptHindsight> furrywolf: without those docs they will have less evidence against you since there isn't enough of a connection of you to your paypal account
[10:23:10] <CaptHindsight> furrywolf: it's for everyones safety
[10:25:12] <MattyMatt> in 2500AD, paypal will have their own predator drone fleet
[10:27:54] <MattyMatt> to compete with the remote control exploding barclaycards
[10:28:25] <MattyMatt> accounts are so 2nd millenium
[10:46:23] <zeeshan|2> well i broke 1 cutter and dulled one cutter to shit
[10:46:26] <zeeshan|2> on 304 last night
[10:46:29] <zeeshan|2> doing one pocket
[10:46:39] <zeeshan|2> why the hell is it so hard to mill
[10:46:41] <zeeshan|2> but so easy to turn?
[10:47:17] <archivist> have to bite under the skin you just made
[10:47:25] <zeeshan|2> i know =/
[10:47:32] <zeeshan|2> i was doing .1 radial doc
[10:47:37] <zeeshan|2> and .125 axial doc
[10:47:51] <zeeshan|2> .002 ipt 4 flute 80 sfm
[10:48:09] <zeeshan|2> no coolant
[10:48:16] <archivist> I bet you tale a lot more on the lathe
[10:48:20] <archivist> take
[10:48:24] <zeeshan|2> nahh
[10:48:31] <zeeshan|2> only .080" on the lathe
[10:48:33] <zeeshan|2> limited by rigidity
[10:48:34] <Tom_itx> wrong feeds
[10:49:04] <Tom_itx> you just have to be more precise on the feed/speeds with 'fussy' materials
[10:49:05] <zeeshan|2> Tom_itx: thats what the yg1 catalog says
[10:49:13] <archivist> and dont forget the reduction as you get to the middle of the cutter
[10:50:02] <Tom_itx> only on plunge cuts
[10:50:11] <zeeshan|2> ??
[10:51:05] <archivist> I do believe he is plunging
[10:51:15] <zeeshan|2> i helix down
[10:51:22] <zeeshan|2> maybe that was the problem?
[10:51:27] <archivist> exactly
[10:51:52] <zeeshan|2> cant you helix down in 1018?
[10:51:58] <archivist> your calcs are for the periphery
[10:53:37] <zeeshan|2> blah ill just make it out of steel
[10:53:40] <zeeshan|2> its just exhaust manifolds :P
[10:53:42] <zeeshan|2> steel is better anyway!
[10:53:52] <Tom_itx> typically your ramp moves will be 1/2 - 1/3 normal feed and that could be your problem
[10:53:58] <Tom_itx> to save the cutter
[10:54:07] <zeeshan|2> oh
[10:54:14] <zeeshan|2> im ramping down at same rate
[10:54:19] <zeeshan|2> whoops
[10:54:35] <Tom_itx> bad idea
[10:54:51] <zeeshan|2> well fak stainless
[10:54:53] <zeeshan|2> ill revisit some other itme
[10:54:58] <Tom_itx> master it
[10:54:59] <zeeshan|2> definitely not for a flange :P
[10:55:01] <Tom_itx> then move on
[10:55:16] <Tom_itx> what better time to learn
[10:55:55] <zeeshan|2> im just gonna make it out of 1018 hr
[10:55:56] <zeeshan|2> for now
[10:56:03] <zeeshan|2> that way i dont even have to buy stainless bends
[10:56:08] <zeeshan|2> cause i have tons of 1.5" sch 40 bends
[10:56:13] <Tom_itx> well fix your ramps anyway
[10:56:17] <zeeshan|2> i will
[10:56:19] <zeeshan|2> for the steel
[10:56:28] <zeeshan|2> for steel i think i can dry cut @ 150 sfm
[10:56:31] <zeeshan|2> to 200 easily
[10:56:35] <zeeshan|2> 0.002"
[10:57:04] <Tom_itx> iirc i don't have room to install xilinx on the ssd...
[11:04:14] <Tom_itx> dammit now i don't have a mouse
[11:05:18] <Jymmm> Tom_itx: with wiskers?
[11:05:31] <Tom_itx> uh huh
[11:05:45] <Jymmm> blame the cat
[11:08:11] <mozmck> What does a xilinx install take now - 100GB? ;)
[11:08:22] <Tom_itx> the zip is 6G
[11:08:53] <mozmck> yeah, I've downloaded it more than once (different versions)
[11:09:08] <Tom_itx> same here
[11:26:04] <Tom_itx> maybe 10.04 is too old for the mb
[11:27:20] <pcw_home> AFAIK 10.04s RTAI kernel wont run on Baytrail MBs
[11:27:30] <Tom_itx> thanks for the info
[11:27:37] <pcw_home> (turns off USB power during boot)
[11:27:41] <Tom_itx> i wanted to try the pcie card out
[11:27:52] <Tom_itx> i'll install wheezie
[11:28:02] <pcw_home> if you have a PS2 KB and mouse maybe
[11:28:10] <Tom_itx> any eta on the 7i90?
[11:28:13] <Tom_itx> nope i tried both
[11:28:38] <pcw_home> ~90 in stock
[11:28:52] <Tom_itx> update your page so i can make it 89
[11:29:33] <pcw_home> we are so behind on store orders I am thinking of closing the store
[11:29:39] <Tom_itx> won't complete the order with 'Out of Stock' showing
[11:29:52] <Tom_itx> well either way i need to get one
[11:30:09] <Tom_itx> do you have buffer chips for it? i could try that route
[11:30:21] <Tom_itx> unless it took out more than that
[11:30:40] <pcw_home> yeah we have pi5C16211s
[11:31:08] <Tom_itx> it probably took out all 4
[11:31:20] <Tom_itx> or is there 3?
[11:31:34] <Tom_itx> i didn't check it, just looking at the board layout
[11:31:37] <pcw_home> 4 (3 for I/O 1 for PP)
[11:31:47] <Tom_itx> well the PP still works
[11:31:54] <Tom_itx> i can talk to it
[11:33:08] <Tom_itx> no io activity in show hal config though
[11:34:18] <pcw_home> you might check the VCC on the bus switches (theres a bypass by each chip)
[11:34:32] <Tom_itx> ok
[11:36:02] <pcw_home> my guess is one chip shorted out (VCC should be 4V)
[11:36:04] <pcw_home> 5V --> 1K --> bus-switch-VCC --> 4.02k --> gnd
[11:36:34] <pcw_home> (when jumpered for 5V tolerant mode)
[11:36:40] <Tom_itx> lemme set the control up and i'll check it
[11:36:42] <Tom_itx> yeah
[11:37:08] <zeeshan|2> #10 no 3 center drill
[11:37:11] <zeeshan|2> er
[11:37:40] <pcw_home> the PP one has a different divider so a GPIO bus swicth failure would not affect it
[11:44:19] <Tom_itx> 1.4v across C8
[11:47:08] <Tom_itx> 3.3v on U1, 5v on U11
[11:47:40] <dutchfish> Tom_itx, thanks (sorry for the late respons)
[11:50:00] <zeeshan|2> http://www.amazon.ca/YG-1-07593TF-Carbide-0-5-Inch-Diameter/dp/B0080AYG5W#productDetails
[11:50:03] <zeeshan|2> lol this must be a mistake
[11:50:09] <zeeshan|2> but i see 28$ for a 1" carbide end mill
[11:50:13] <zeeshan|2> "save 349$"
[11:51:31] <Tom_itx> pcw_home and 3.3v and 5v at the jumper
[11:52:06] <Tom_itx> nothing "looks" bad but no io... no magic smoke appeared
[11:52:48] <Tom_itx> tried all 3 headers
[11:53:18] <pcw_home> check at W1 (w6 just selects cable power)
[11:54:24] <Tom_itx> 1.49 & 5v
[11:54:44] <Tom_itx> the 1.49v is on the selected jumper to the chips
[11:54:59] <dirty_d> do you guys use engineering equations when designing stuff or just do it by feel?
[11:55:32] <dirty_d> like i need to make something thats 5ft high that supports a load of 300lb offset 16" to one side
[11:55:40] <dirty_d> basically a tall upside down L
[11:55:44] <pcw_home> should be 4V on top and 5V on bottom (you may see smoke if you change the jumper)
[11:55:58] <Tom_itx> we don't wanna see smoke
[11:56:24] <pcw_home> 1.49v means at least one bus switch chip is damaged
[11:56:33] <Tom_itx> i figured
[11:56:34] <dirty_d> i figure 2.5"x0.125" 6061 square tube is strong enough right?
[11:56:45] <Tom_itx> most likely the one that was in use
[11:57:31] <Tom_itx> are they top to bottom P1 2 & 3?
[11:57:36] <pcw_home> you might try with a current limited 5V supply, jumper W1 for 3.3 tolerance and see if any switches get hot
[11:58:19] <Tom_itx> 1k across the 5v input?
[11:58:44] <Tom_itx> parallel
[11:58:52] <Tom_itx> err series...
[11:59:19] <pcw_home> no just a 1A or so limited 5V supply so if the chip really goes up you dont lose any traces
[12:00:05] <Tom_itx> i'll check the fuse in the 5v and see what it is.. don't really have a current limited supply
[12:00:17] <Tom_itx> not too excited to try this
[12:00:39] <pcw_home> so what happened is you put 24V? on the 5V supply this would try to power the bus switches with 20v through a 1K resistor
[12:01:06] <Tom_itx> the 5v reg was showing 23v and i hit the switch real quick
[12:01:23] <pcw_home> probably one bus switch shorted out
[12:01:52] <Tom_itx> i'd bet on that too since everything else seems ok
[12:02:14] <Tom_itx> i wish i had a hot air gun
[12:02:17] <pcw_home> safer heat test: jumper 3.3V to W1 middle pin
[12:02:23] <Tom_itx> removing those isn't the easiest
[12:02:51] <Tom_itx> that won't screw up the 3.3 reg?
[12:04:42] <pcw_home> its protected
[12:05:55] <pcw_home> remove W1 and W6 jumpers
[12:05:56] <pcw_home> connect W6 bottom (3.3V) to W1 center
[12:05:57] <Loetmichel> *hihi* the shirts my wive gifted me are washed now... should i notice something from the writing on them? -> http://www.cyrom.org/palbum/main.php?g2_itemId=15798
[12:06:04] <Tom_itx> can i use the 3.3 on the bottom of W6 for that?
[12:06:09] <Tom_itx> ok
[12:06:53] <pcw_home> much safer than 5V because an internal short cant put 5V on the FPGA pins
[12:07:11] <Tom_itx> leave the W6 jumper on?
[12:07:22] <Tom_itx> top 2 pins
[12:07:42] <pcw_home> doesnt matter (thats just the connector pin 49 connection)
[12:08:38] <Tom_itx> ok bottom of W6 to middle of W1
[12:08:38] <pcw_home> the bad chip wont necessarily heat up enough to detect but worth a try
[12:10:12] <Tom_itx> 20 sec test, no noticeable change in heat and 3.3v didn't drop any
[12:11:21] <pcw_home> if it does not heat up at 3.3V you should be able to try reading the pins through HAL and find the bad bus switch that way
[12:11:54] <pcw_home> (since with 3.3 v they should sort of work)
[12:12:10] <Tom_itx> so leave it jumpered and test it in hal?
[12:12:22] <pcw_home> yeah again worth a try
[12:12:57] <pcw_home> (definitely _not_ going to work at 1.49V)
[12:15:24] <Tom_itx> so pin 1 on each header would be IO0 24 48, i'll watch those in hal to start
[12:26:20] <pcw_home> yea just ground them with a jumper
[12:26:21] <Tom_itx> IO0 doesn't switch IO24 & 48 do
[12:26:29] <Tom_itx> so one bad chip
[12:26:43] <pcw_home> sounds like it
[12:27:03] <Tom_itx> probably U3
[12:27:45] <Tom_itx> i'd still like to get a spare board
[12:29:44] <pcw_home> may need to ohm it out
[12:29:45] <pcw_home> I'll add the 7I90s to the store when the 7I77 mess gets straightened out
[12:30:40] <Tom_itx> is IO0 special? i noticed there was no 'out' on it in hal
[12:31:21] <pcw_home> no, its probably an enabled encoder input or something
[12:32:32] <pcw_home> (so you cannot set it into output mode)
[12:32:56] <Tom_itx> maybe i should test another pin on that header
[12:33:21] <Tom_itx> it should still read the input though..
[12:33:22] <pcw_home> well unless you disable the special function in hal
[12:33:53] <pcw_home> yes that should always work (even on outputs)
[12:34:55] <Tom_itx> i still get nothing on IO 0 1 & 2
[12:36:02] <pcw_home> those must all be on the top chip
[12:36:14] <Tom_itx> makes sense
[12:36:25] <Tom_itx> that's how i would have layed it out :)
[12:36:37] <pcw_home> but 24 and 48 are also so ???
[12:36:45] <Tom_itx> huh?
[12:36:50] <Tom_itx> 24 & 48 worked
[12:37:45] <Tom_itx> so it's not a chip for each header?
[12:37:50] <Tom_itx> rather intermixed?
[12:38:11] <pcw_home> no, they are intermixed
[12:38:40] <Tom_itx> well that just sucks
[12:38:58] <pcw_home> what was connected to P1 when it got 23V?
[12:39:20] <Tom_itx> iirc the 7i47s
[12:39:25] <Tom_itx> or nothing
[12:39:44] <Tom_itx> that's where it goes but i may have had it disconnected at the time of failure
[12:40:11] <pcw_home> which is probably a good thing
[12:40:17] <Tom_itx> heh yeah
[12:40:50] <Tom_itx> i was gonna test it with the pcie card but it's a pita to get wired up
[12:40:53] <pcw_home> I dont seem to have a 7I90 schematic anywhere I can get to
[12:41:24] <Tom_itx> so i may just take a chance on the 7i43s
[12:41:35] <Tom_itx> i have the 7i43 to fall back on but would rather not
[12:42:45] <pcw_home> I will get the 7I90s on the store but it will be a while
[12:42:47] <pcw_home> do you just need longer cables for the 6I24?
[12:43:00] <Tom_itx> i can make one up
[12:43:04] <Tom_itx> how long can it be?
[12:43:20] <Tom_itx> i've got some 50 pin ribbon but gradually running out of it
[12:44:08] <Tom_itx> i've got one 8" that might reach but i doubt it
[12:44:23] <Tom_itx> not sure i have enough left to make a longer one but i can get it locally
[12:44:46] <Tom_itx> next tuesday
[12:45:30] <Tom_itx> that's why i was setting up the asrock board
[12:45:39] <Tom_itx> guess i'll have to install wheezy on it
[12:46:45] <Tom_itx> off to run some errands
[13:08:15] <_methods> welding in tennis shoes = bad idea lol
[13:17:48] <dirty_d> how does a non-inverter tig like this http://www.lincolnelectric.com/assets/global/Products/k1478-5/e335.pdf produce a square wave?
[13:18:21] <dirty_d> can i modify my AC/DC stick welder to produce a square wave for aluminum?
[13:21:05] <SpeedEvil> The easy way would be AC-> rectified DC-> big cap -> inductor -> h-bridge
[13:22:08] <SpeedEvil> I assume squarewave is to avoid it ging out at zero cross?
[13:23:22] <dirty_d> yes
[13:23:28] <dirty_d> but i dont think they have an inverter
[13:23:36] <dirty_d> they had square wave tigs before they had inverter tigs
[13:23:47] <SpeedEvil> dirty_d: patent.google.com
[13:23:55] <SpeedEvil> look up 'square wave welding'
[13:24:05] <SpeedEvil> I suspect you'll find some relevant ones in 1970 or whenever
[13:24:10] <SpeedEvil> patents are awesome
[13:24:43] <SpeedEvil> https://www.google.com/patents/US3999034?dq=square+wave+welding+aluminium&hl=en&sa=X&ei=s8BgVYTkA8ve7Abl8IHQCg&ved=0CDAQ6AEwAg
[13:25:23] <SpeedEvil> https://www.google.com/patents/EP0612576A1?cl=en&dq=square+wave+welding+aluminium&hl=en&sa=X&ei=s8BgVYTkA8ve7Abl8IHQCg&ved=0CD4Q6AEwBA
[13:25:24] <SpeedEvil> ...
[13:28:25] <dirty_d> oh, i guess i cant because it uses two power supplies
[13:28:41] <dirty_d> i guess i can still use ac sine wave tig though
[13:28:51] <dirty_d> the tig welders hi frequency start still works
[13:29:07] <dirty_d> just not the power
[13:49:18] <dirty_d> SpeedEvil, like you said i really just need an h-bridge to turn my DC arc welder into a square wave ac tig right?
[13:49:35] <dirty_d> just switch the h-bridge at the duty cycle and frequency i want?
[13:49:45] <SpeedEvil> Pretty much
[13:49:57] <dirty_d> im not sure how smooth the supplied dc will be though
[13:50:04] <dirty_d> i dont know if it wil really be a square wave
[13:50:09] <SpeedEvil> It doesn't really matter.
[13:50:29] <SpeedEvil> The arc won't really go out if the current drops to 70% of nominal - say
[13:50:30] <dirty_d> doesnt it need fast rise and fall time to not let the arc go out though?
[13:50:33] <dirty_d> ok
[13:50:50] <SpeedEvil> minor ripple doesn't matter - as long as it doesn't fall to (guess 20%)
[13:50:58] <dirty_d> tig welding with the dc output is very smooth, so i dont think its just rectified AC output
[13:51:16] <dirty_d> not sure how it does taht though
[13:51:48] <SpeedEvil> There is likely a large inductor involved
[13:52:25] <dirty_d> yea, trying to find a schematic
[13:53:11] <dirty_d> those igbt modules on ebay are pretty cheap, so i might give it a try
[13:55:52] <dirty_d> i wonder why the DC current settings are half of the AC settings
[13:56:11] <dirty_d> only goes to 125A DC
[13:58:32] <dirty_d> oops
[13:58:51] <dirty_d> maybe the resistance of the inductor for DC reduces the max current?
[14:07:00] <SpeedEvil> possibly
[14:07:06] <SpeedEvil> or the voltage is higher
[14:07:57] <dirty_d> hmm, i dont think this will work
[14:08:11] <dirty_d> the source is high inductance
[14:08:27] <dirty_d> so when the transistors turn off, the IGBTs will get fried wont they?
[14:08:48] <dirty_d> tehy only freewheel when the load has inductance
[14:09:48] <SpeedEvil> The inductance is quite high capacitance
[14:10:02] <SpeedEvil> the switching time of the h-bridge should be ~20us or so.
[14:10:11] <SpeedEvil> The inductance can't really change voltage fast
[14:11:30] <dirty_d> actually, since the welder is current limited i can just turn on the other switches before i turn off the other ones
[14:11:51] <dirty_d> so the supply will short to ground for a very short time
[14:14:15] <dirty_d> hmm, but if i break the arc, same problem
[14:15:14] <dirty_d> maybe, i dunno
[14:15:31] <dirty_d> i cant break the arc instantly
[14:19:14] <dirty_d> or i guess icould put like a 100V high power zener diode across the welder output
[14:22:36] <SpeedEvil> dirty_d: yes, you can
[14:23:41] <dirty_d> http://www.digikey.com/product-detail/en/1N3344B/1N3344B-ND/306760
[14:24:20] <dirty_d> 50ohm impedance will be a problem wont it?
[14:26:45] <SpeedEvil> Err - what?
[14:26:53] <SpeedEvil> Oh
[14:27:42] <SpeedEvil> What that means sis that it's a 130V diode. around the 130V voltage, as it's a 50W diode, it passes half an ampish
[14:28:10] <SpeedEvil> 50 ohms means the current changes 20mA/V, so it turns on fully in about 20V
[14:28:25] <SpeedEvil> so it's 'off' at 110V
[14:28:35] <dirty_d> wont it have to handle like 100A for a short time?
[14:28:44] <SpeedEvil> I don't know
[14:31:43] <dirty_d> max dc zener current, 310mA
[14:31:46] <SpeedEvil> http://www.ebay.co.uk/itm/Halogen-Stabbrenner-230V-2000W-R7s-333mm-15700-/380840048936?pt=LH_DefaultDomain_77&hash=item58abd5f928
[14:33:05] <dirty_d> whats that for?
[14:33:33] <SpeedEvil> dumping power
[15:08:19] <barjunk> I'm getting this error: linear move in MDI would exceed joint 0’s positive limit
[15:08:51] <barjunk> I'm just starting testing so the motors are hooked up but not placed in the machinery
[15:09:14] <barjunk> I do not have any limit switches at this point.
[15:09:28] <barjunk> What are the possible reasons this message would appear?
[15:09:34] <dirty_d> in yout ini file there are a negative and positive limit for each axis
[15:09:41] <barjunk> OK
[15:09:53] <dirty_d> for got the anme, but its obvious if you see it
[15:10:09] <barjunk> Let me check that real quick...just a sec.
[15:10:13] <dirty_d> ok
[15:11:47] <barjunk> max limit 8
[15:12:08] <barjunk> In the MDI I'm issuing G0 X13
[15:12:24] <barjunk> How do I verify the 8 is in inches?
[15:12:39] <barjunk> or how do I verify what that number represents?
[15:12:55] <dirty_d> theres another thing in there that sets inches or mm
[15:12:55] <barjunk> I'll try issuing a smaller number...
[15:13:00] <dirty_d> cant remember what, but its in the docs
[15:13:09] <barjunk> ok. I'll poke around for that.
[15:14:19] <barjunk> I feel like such a dweeb
[15:14:50] <barjunk> What is weird is that the MDI window keeps a history and from that, it showed previous entries bigger than 8
[15:15:08] <barjunk> Doesn't matter though...it's working, I can move forward.
[15:18:04] <barjunk> thanks dirty_d for the guidance.
[15:18:44] <MrSunshine> hmm anyone here know .. there was a person doing machine work on a taig lathe/mill on youtube .. he spoke some strange language... quite skilled guy imo .. but cant remember what his channel on youtube was .. anyone has any ideas for me? =)
[15:26:03] <PetefromTn_> Hey guys I need some help
[15:26:29] <PetefromTn_> for some reason my VMC has lately been forgetting the G54 offsets I setup when I shut it down
[15:26:43] <PetefromTn_> then today I went out to the shop to setup a new program
[15:27:22] <PetefromTn_> and touched off the new tool I created at the G59.3 G0 X0Y0 position which I put at the right rear corner of the table
[15:28:03] <PetefromTn_> for some reason when I should be getting tool length offsets in the 17 inch range I am now getting 70 plus inch TLO numbers when I touch off..
[15:28:32] <Tom_itx> not MM again is it?
[15:28:38] <PetefromTn_> I checked the G59.3 Z position which should be at the top of the column in that corner of the table
[15:28:40] <Tom_itx> sounds like it
[15:28:43] <PetefromTn_> shouldn't be
[15:28:54] <PetefromTn_> I converted the entire machine to inch awhile ago
[15:29:41] <PetefromTn_> any idea why it would forget my offsets upon shutdown?
[15:30:03] <Tom_itx> they are stored in a file
[15:30:28] <PetefromTn_> is there any order of power down that would make it forget?
[15:30:55] <Tom_itx> i can't remember :)
[15:31:06] <Tom_itx> i don't think so
[15:31:10] <Tom_itx> it's stored in a file
[15:31:14] <PetefromTn_> I usually disable the servos and then hit the Estop button then I shut down the linuxCNC program and then turnoff the PC
[15:31:42] <PetefromTn_> really frustrating here
[15:33:29] <barjunk> So you are saying, that if you make a change, shutdown the program then restart...it always changes back?
[15:33:33] <barjunk> or just sometimes?
[15:35:17] <barjunk> Tom_itx, so if I use touch off, it should store that info in the ini file?
[15:35:28] <barjunk> I thought it only stayed for that session?
[15:35:29] <PetefromTn_> I am saying that I set G54 to someplace on my vise for a program
[15:35:39] <PetefromTn_> then when I shut down after making some parts for the day
[15:35:50] <PetefromTn_> and start back up the next day and home the machine
[15:36:24] <PetefromTn_> then do a G54 G0X0Y0 it usually runs to the table all the way back and to the right...
[15:36:27] <PetefromTn_> not sure why really
[15:36:53] <PetefromTn_> that is the OPPOSITE of the G59.3 position I use so It can't be switching the two offsets somehow....
[15:37:19] <barjunk> It seems like it thinks home is in the exact opposite for the home position.
[15:37:45] <barjunk> Any chance that the connections to the motors got turned around or something?
[15:38:49] <PetefromTn_> naah it is nothing like that and the home sequence works perfectly..
[15:39:00] <PetefromTn_> have not changed anything..
[15:39:14] <barjunk> so now, each time you start up you have to issue the G54 command, right?
[15:39:31] <PetefromTn_> well I don't have to
[15:39:42] <PetefromTn_> but when I am running the same program I ran the day before
[15:40:01] <PetefromTn_> and I go to the G54 location to setup my Z offset for the run
[15:40:28] <PetefromTn_> it goes to the corner of the tables limits like the opposite of the G59.3 I use to setup TLO's with
[15:40:43] <barjunk> I got nothin... :0
[15:41:24] <PetefromTn_> I don't understand it either..
[15:41:37] <PetefromTn_> it never forgot offsets before
[15:41:44] <PetefromTn_> just started that a week or two ago
[15:42:05] <PetefromTn_> now it is forgetting it all the time and this tool length issue is a real problem
[15:42:20] <barjunk> Can you think of anything that has changed just before all that...like an update or something?
[15:42:28] <PetefromTn_> If I set G59.3 with the Millhead all the way up to Z0
[15:42:52] <PetefromTn_> and then click the DRO tab it says something like 71.6590 or something like that
[15:43:02] <PetefromTn_> I don't really ever update this thing
[15:43:16] <barjunk> which is probably a good move...
[15:43:20] <Tom_itx> something changed. figure out what changed
[15:43:48] <barjunk> Any chance you use that computer for anything else?
[15:44:40] <PetefromTn_> never
[15:45:09] <barjunk> Any chance someone that isn't supposed to play with your mill, has?
[15:45:18] <barjunk> or at least the computer?
[15:45:50] <PetefromTn_> nobody touches this machine but me
[15:46:15] <barjunk> I'm assuming that there is absolutely no connectivity on that gear, wireless or wired...is that right?
[15:47:20] <PetefromTn_> the only time this machine was connected to the internet cable was when we were programming it and that was quite awhile ago
[15:48:06] <barjunk> so if you make an adjustment now in the software...it will stick for the next run, right?
[15:48:53] <PetefromTn_> not if you shut down the machine in the interim
[15:49:20] <barjunk> and the machine you are referring to is the mill....not the computer that runs it, right?
[15:50:17] <PetefromTn_> no everything its a VMC all integrated
[15:50:53] <barjunk> hmmm...I don't know enough about that....this seems specific to storage or permissions
[15:51:30] <barjunk> I was going to have you make a change, close the linuxcnc software, then restart the software to ensure it stayed.
[15:52:28] <barjunk> If not, then whatever place that linuxcnc writes its changes to , isn't
[15:53:22] <barjunk> but since it is all integrated, I'm a little at a loss for how it all works together.
[15:53:35] <barjunk> got a link for the machine you are using??
[15:53:52] <barjunk> so I can take a look and maybe produce some other thoughts?
[15:55:07] <barjunk> model number?
[15:55:20] <_methods> did you try turning it off and turning it back on again lol
[15:55:57] <_methods> oh nm that'
[15:55:59] <PetefromTn_> yeah I turned off the linuxCNC program
[15:56:07] <_methods> i was just being a smartass
[15:56:12] <PetefromTn_> it is a Cincinatti Arrow 500 VMC
[15:56:31] <PetefromTn_> retrofitted to linuxCNC with basically brand new motors and drives and everything
[15:56:39] <_methods> have you changed between g20 and g21?
[15:56:44] <witnit> i want pictures pete
[15:57:19] <_methods> put in a TLO while g21 active?
[15:57:35] <_methods> i'm just spitballin here
[15:57:55] <_methods> does the demo program load up with g21 active?
[15:58:27] <_methods> i've never really paid attention since i prefer to use metric myself
[15:59:02] <PetefromTn_> pictures of what?
[15:59:39] <witnit> your build
[15:59:41] <PetefromTn_> my programs have G20 in there
[16:00:21] <PetefromTn_> there is a build thread with some pictures over on the CNCzone in the Cincinatti Forum called Pete's Cincinatti Arrow 500 Adventure if you want to look at it.
[16:00:43] <witnit> yes, yes i do :)
[16:00:54] <PetefromTn_> It has been making me beautiful parts and money for about a year now but I STILL don't have the toolchanger working ;)
[16:01:13] <witnit> oh pete, lets just fix it once and for all =D
[16:01:19] <witnit> whats the main problem?
[16:02:46] <_methods> i don't think we have the skillz to fix pete's main problem lol
[16:02:47] <PetefromTn_> this is the MAIN problem LOL
[16:03:11] <PetefromTn_> the main problem right now I want help with is this offset issue..
[16:03:13] <witnit> oh hahah i came in ate, i will go look at the logs :)
[16:03:13] <PetefromTn_> Ball buster
[16:03:25] <witnit> late*
[16:04:56] <PetefromTn_> no worries
[16:05:26] <PetefromTn_> I am going to play with it here and see if I can figure out what is going on..
[16:10:30] <andypugh> Oh dear. My Mill has died.
[16:11:40] <renesis> andypugh: like completely? did it melt?
[16:11:49] <andypugh> But I can’t see what the problem is because something in my version of LinuxCNC is spamming the dmesg
[16:11:57] <andypugh> No, it’s just something with the computer
[16:11:58] <andypugh> http://pastebin.com/Hf3Cmprp
[16:20:46] <PetefromTn_> Well thats strange.
[16:20:56] <PetefromTn_> I just powered down the entire machine and waited a minute
[16:21:00] <PetefromTn_> then powered it back up
[16:21:03] <PetefromTn_> homed the axes
[16:21:30] <PetefromTn_> and after the homing procedure the X and Y look right but the Z axis is showing -71.4512???
[16:21:34] <PetefromTn_> WTF?
[16:22:22] <andypugh> Relative or machine?
[16:22:49] <PetefromTn_> hang on
[16:24:29] <PetefromTn_> sorry it is relative machine coordinates look right
[16:24:49] <PetefromTn_> AND I think it was still in G59.3 offset
[16:24:59] <PetefromTn_> which is kind of the problem I am having
[16:25:05] <PetefromTn_> how do you clear out an offset?
[16:25:10] <andypugh> Is there a tool length compensation active? And is the tool table right?
[16:25:28] <PetefromTn_> I tried to set a new tool
[16:25:35] <andypugh> G10 L20 I think
[16:25:36] <PetefromTn_> and did it the same way I always do
[16:25:53] <PetefromTn_> and the offset was sort of compounded on me for some reason
[16:25:58] <andypugh> One of the G10 commands lets you zero the offset
[16:26:05] <PetefromTn_> it SHOULD have been like 17 or so
[16:26:19] <PetefromTn_> but it is now -71.4512!!
[16:35:45] <Tom_itx> PetefromTn_ you must select a tool for Z to be right
[16:37:50] <Tom_itx> andypugh any idea how long a 50pin ribbon can be without problems?
[16:38:17] <andypugh> No idea. And it probably matters a lot what you are using it for.
[16:48:47] <Tom_itx> between a 6i24 and 7i47s
[16:50:57] <andypugh> You would need to ask PCW
[16:52:24] <Tom_itx> it's obvious short is better
[16:52:50] <andypugh> That’s what I tell the girls.
[16:53:15] <Tom_itx> any buy it?
[16:53:50] <andypugh> Not so far
[17:11:56] <varesa> what is the reason that if I assign a pwmgen output to parport.0.pin-17-out I don't get anything but it works on other pins like parport.0.pin-01-out?
[17:12:18] <varesa> e.g. if I look at the signal with HAL Scope
[17:14:37] <PetefromTn_> Okay guys I got it sorted somehow..
[17:14:47] <PetefromTn_> managed to get my prototype machined..
[17:14:52] <PetefromTn_> at least the first half..
[17:14:55] <Tom_itx> http://linuxcnc.org/docs/html/hal/parallel_port.html#_pins
[17:15:09] <Tom_itx> varesa, that shows the pins and their direction i believe
[17:16:21] <varesa> Tom_itx: I was just looking at the diagram above that and it should be an output in both configurations
[17:17:06] <Aero-Tec> for my lathe
[17:17:29] <Aero-Tec> does it matter if I have fixture or work set?
[17:18:08] <Aero-Tec> if I load tool 1 and zero off my work
[17:18:20] <Tom_itx> if it didn't mater you wouldn't have a choice but i don't know which
[17:18:44] <Aero-Tec> and use that offset for adding to tool table
[17:19:07] <Aero-Tec> would that be the same as zeroing off fixture and when adding to tool table
[17:19:42] <Aero-Tec> should correct the only diff is the work or tool setting
[17:20:08] <Aero-Tec> the zero would be the exact real work place
[17:20:16] <PetefromTn_> http://i.imgur.com/VuCqR7x.jpg
[17:20:48] <Aero-Tec> nice
[17:21:31] <PetefromTn_> I would recommend locating your tools off a fixed point that is NOT on the workpiece for tool offsets. Work offsets should be on the stock somehow..
[17:22:40] <Aero-Tec> I have one axis setting fixture offset
[17:22:50] <PetefromTn_> thanks man
[17:22:56] <PetefromTn_> it is a Work in progress LOL
[17:23:16] <andypugh> varesa: Have you checked with a physical scope?
[17:23:20] <Aero-Tec> the Z is a tad more involved
[17:23:40] <andypugh> varesa: I would expect PWm to be possible on any pin
[17:23:40] <t12> today i obtained ze german kamera
[17:24:03] <t12> https://www.dropbox.com/sc/x0gz7birt3l2bsc/AAAnleYR84XdCj8V79px7uYaa
[17:24:45] <varesa> andypugh: I have, same result
[17:24:53] <Aero-Tec> I have a large chuck and quick change Colletes options that I switch between
[17:25:01] <SpeedEvil> http://imgur.com/gallery/ViEfT - awesome
[17:25:08] <SpeedEvil> slowmo machining
[17:25:13] <Aero-Tec> so a common zero is not easy
[17:25:13] <andypugh> Presumaby Halscope sees the output of the PWMgen?
[17:25:24] <t12> i think thats all from the ingersoll-rand youtube?
[17:25:28] <t12> ya
[17:27:29] <SpeedEvil> yeha
[17:27:48] <Deejay> gn8
[17:32:49] <PetefromTn_> cool...
[17:42:53] <varesa> okay, after reloading the hal stuff I got the output to appear on the HAL scope on either pin
[17:43:12] <varesa> and I found out that my cable is missing pin 17 :-/
[17:43:57] <andypugh> Not all cables are fully wired.
[17:46:38] <_methods> you get it fingered out PetefromTn_
[17:46:50] <_methods> i'm too tired to be of any assistance
[17:47:08] <_methods> been doing yard work, welding and machining all day time to go eat and pass out
[17:50:22] <_methods> PetefromTn_: you are going to kill me i lost 4 rotabs at the last auction
[17:50:31] <_methods> 4 tsudakoma rn-100's
[17:50:45] <_methods> 2 of them were 4 station rotabs
[17:51:02] <_methods> i got up to $250 and quit and that's what they went for lol
[17:53:12] <PetefromTn_> Oh damn man I would have been game for that or even slightly more..
[17:53:41] <PetefromTn_> Tsudakoma is a good name I think...never used one tho.
[17:55:53] <PetefromTn_> _methods Did you see my part I just posted..
[18:26:25] <MattyMatt> Tom_itx, the range on 50 pin will be much greater if it's using differential pairs.
[18:27:08] <MattyMatt> but single ended, on old school 74LS signals, that ribbon cable was only good for 10ft at best
[18:31:19] <MattyMatt> _methods, you never know what the other guy woulda gone up to. you wanted it 2nd best, that's all you'll ever really know
[18:32:39] <furrywolf> it's especially fun that, once an item is past what you want to spend, to figure out how much the other guy is willing to spend, and make sure he pays it. :P
[18:33:20] <MattyMatt> that's a dangerous game on ebay, because he'll do the same to you on the next one :)
[18:33:27] <furrywolf> the risk is, of course, you guess wrong, and end up getting it yourself, for more than you wanted to spend.
[18:38:17] <roycroft> i *knew* it
[18:38:32] <roycroft> furrywolf is actually that guy who dresses all in black on "storage wars"
[18:40:33] <malcom2073> The senile dude?
[18:40:41] <malcom2073> Or the guy who runs the huge junk store?
[18:40:48] <roycroft> the one that everybody hats
[18:40:49] <roycroft> hats
[18:40:52] <roycroft> hates, dammit
[18:41:11] <malcom2073> The "yeeeeaaapppp" guy?
[18:41:15] <roycroft> yes!
[18:41:20] <malcom2073> They all hate each other :-P
[18:41:23] <malcom2073> But yeah haha
[18:41:37] <roycroft> they all compete with each other
[18:41:40] <roycroft> but they all hate that guy
[18:44:05] <MattyMatt> I am blessed with ignorance of this programme
[18:44:45] <MattyMatt> I've a horrid feeling I've seen enough on YT to know who you mean tho
[18:45:49] <MattyMatt> do they do impound auctions too? I remember a speedboat
[18:46:09] <MattyMatt> or maybe I'm confusing with stewie griffin's death ray
[18:46:18] <roycroft> i don't watch it on a regular basis, but i've seen it
[18:46:39] <roycroft> there's a lot of trying to get the bad guy to overbid going on on that show
[18:56:20] <andypugh> My thumb nail is in the process of falling off after a subungual haematoma. I wonder if it is worth trying to glue it back in place with superglue?
[18:57:30] <roycroft> duct tape will hold it in place
[19:00:47] <andypugh> Except when I want to change the duct tape to match my outfit, and peel the nail off with the tape.
[19:03:05] <roycroft> you can spray paint it
[19:03:29] <roycroft> it would take quite a few layers of paint before you would have to reapply the duct tape
[19:05:00] <MattyMatt> on Operation Ouch, they taped a fingernail back on as a temporary scab
[19:05:33] <MattyMatt> but the doc said there was no chance of it retaking, a new one would grow and force it off
[19:06:37] <CaptHindsight> andypugh: I'd use epoxy unless you're going to be outdoors often, then I'd use a polyurethane
[19:07:11] <MattyMatt> shapelock is the amputee's friend. polycaprolactone
[19:07:38] <MattyMatt> I'm not sure I'd like to mould it around an open wound at 60C, but on skin it's fine
[19:07:56] <roycroft> did you drill through the nail to release the pressure?
[19:07:59] <andypugh> Yes, the new nail is pushing the old one off. But it is going to take a year to re-grow properly
[19:08:56] <andypugh> roycroft: Yes. It’s a curious thing that drilling a hole in yourself normally feels like a really bad idea. But after 24 hours of pain and no sleep it starts to feel like the best idea.
[19:09:21] <roycroft> i haven't had that happen to me in a long time, but drilling a hole through the nail definitely helped
[19:09:32] <roycroft> there was intense,throbbing pain until i relieved the pressure
[19:09:50] * MattyMatt carefully sets depth stop on drill press
[19:10:02] <MattyMatt> hmm, what for clamping?
[19:10:20] <MattyMatt> thumbscrew, I knew I'd find a use for them again
[19:11:26] <andypugh> It’s a very strange sort of injury. One very wierd thing was that is spontaneously started bleeding round the edge of the nail 3 weels later.
[19:11:48] <andypugh> I was working on my lathe, and realised I was dripping.
[19:12:24] <MattyMatt> it takes a while to decide it wants to shed. it was a few days when I did a finger
[19:12:29] <MattyMatt> iirc. I was small
[19:13:38] <andypugh> I am amazed that I haven’t done it before.
[19:13:45] <MattyMatt> playing in a burnt out car, put my finger in the bonnet pinch when someone slammed it shut
[19:16:20] <XXCoder> wheee
[19:16:24] <XXCoder> built new kickass pc
[19:16:30] <XXCoder> no cd drive lol
[19:17:13] <MattyMatt> yeah someone mentioned that recently. cd are going the way of floppies
[19:17:37] <XXCoder> I built it without one because dont need it generally, so dont wanna buy one
[19:17:46] <XXCoder> but unsure how to install os on it though lol
[19:17:59] <malcom2073> USB stick
[19:18:05] <malcom2073> pretty much any OS you'd want to use, is USB installable
[19:18:15] <MattyMatt> with modern bios
[19:18:19] <XXCoder> yeah was thinking some linux distro
[19:18:23] <andypugh> The CD drive on the side of my iMac mainly functions as a place to lose SD cards as it is right above the SD card slot.
[19:18:29] <XXCoder> not sure which though
[19:18:34] <malcom2073> Both windows and linux support usb sticks
[19:19:02] <CaptHindsight> http://www.cbc.ca/news/canada/montreal/montrealer-sets-world-record-for-furthest-flight-by-hoverboard-1.3085052
[19:19:11] <MattyMatt> why not the Wheezy with linuxcnc?
[19:19:24] <XXCoder> was thinking it may be time to finally get rid of windows. is therte office application for linux that supports import of outlook 2010
[19:19:27] <XXCoder> nah
[19:19:35] <XXCoder> I has computer for it already
[19:20:19] <MattyMatt> Gnome 3 is pretty horrid, and unusable on my ancient 1 core thinkpads
[19:20:29] <XXCoder> lol yeah plan to use xkcd
[19:21:25] <CaptHindsight> https://www.youtube.com/watch?v=U-3Ql7G7qRc still better 40 years ago
[19:24:26] <MattyMatt> segways all you need
[19:24:49] <XXCoder> segway nah not till it can last many miles
[19:25:17] <MattyMatt> I meant to splatter your head, not to get anywhere :)
[19:26:08] <XXCoder> CaptHindsight: what does it use to fly? I has doubt
[19:26:16] <MattyMatt> I want a robomule that can go and fetch 8x4 plywood from the store
[19:26:42] <MattyMatt> for personal transport I has feets
[19:26:59] <MattyMatt> and an ebike, and a modern public transport system
[19:27:08] <XXCoder> Still waiting for elio
[19:27:25] <MattyMatt> 95% of an ebike. it runs I just gotta finish the bracket for the batteries
[19:29:48] <Aero-Tec> I am trying to add tools to table for my lathe
[19:30:21] <Aero-Tec> in the past this has been very scary as I can mess things up and have crashes
[19:30:40] <Aero-Tec> if I zero tool 1
[19:31:17] <Aero-Tec> to a test work stock in lathe
[19:32:08] <Aero-Tec> can I use that zero to add tool to tool table by touch off to tool table?
[19:32:35] <Aero-Tec> and would that also be ok for all the tools already in tool table?
[19:34:49] <Aero-Tec> as in would there zero setting still be right if they were right in the first place, even tho the real world zero used to zero them was not the same zero used for the new zero for the new tool?
[19:35:20] <Aero-Tec> does that make sense?
[19:35:58] <CaptHindsight> XXCoder: http://en.wikipedia.org/wiki/Williams_X-Jet
[19:36:03] <andypugh> Aero-Tec: I have one tool that I think of as the “master” tool and that always has zeros in the tool table
[19:36:12] <XXCoder> reading
[19:36:19] <andypugh> And the other tool table entries are relative to that one
[19:36:33] <Aero-Tec> that is what I need to do
[19:36:33] <andypugh> And the tool table is populated entirely by touching-off.
[19:37:03] <XXCoder> interest9ng
[19:37:04] <andypugh> So, machine a diameter with tool 1, set the G54 offset so that the diameter is correct.
[19:37:25] <andypugh> Machine with tool 2, set the _tool_ offset so the diamter is correct, and so on.
[19:38:10] <Aero-Tec> tool 2 would be set to tool table
[19:38:22] <SpeedEvil> https://www.youtube.com/watch?v=w9dskxN10N0 cutting steel with bacon
[19:38:27] <Aero-Tec> what about the fixture or work setting?
[19:39:22] <andypugh> One the tools are set up, the diameter never changes. But you can touch-off Z on a job by job basis.
[19:39:51] <andypugh> I typically jog to close to the metal, touch-off at 1mm, then face to zero.
[19:40:59] <andypugh> “engineering grade of bacon” :-)
[19:42:08] <malcom2073> That's bacon trimmed to a thickness of 0.0005?
[19:42:40] <Aero-Tec> andypugh, what I was doing was using tool 1 to machine the end of stock, set Z zero with workpiece and g54, then cut the dia and measure and set the X of g54
[19:43:26] <andypugh> As long as you check that tool 1 has zero in the offsets that is the same as what I do
[19:43:36] <Aero-Tec> then put in new tool and use a feeler gage to set the Z of new tool to the machined end of the stock using tool 1
[19:43:46] <Aero-Tec> do a touch off to tool table
[19:43:58] <andypugh> Then I typically forget to switch from T fo G54 at a critical point and have to start agian.
[19:44:06] <Aero-Tec> would that be a good way to set up a tool table using touch off?
[19:44:32] <Aero-Tec> lol
[19:44:34] <andypugh> It is the way I have always donw it on the lath
[19:44:38] <Aero-Tec> been there done that
[19:45:23] <Aero-Tec> just wanted to make sure doing it that way would not mess up the tool setting I have now and have to redo them all
[19:45:40] <Aero-Tec> I have had to do redoes more times then I want to say
[19:46:38] <Aero-Tec> the tool table is growing and getting to where a complete redo is lots of extra work
[19:46:58] <Aero-Tec> andypugh, thanks a mill for the help
[21:00:43] <barjunk_> I've read through the docs, but I must be missing something...
[21:01:17] <barjunk_> How do I calibrate the stepper against an actual measurement
[21:01:39] <barjunk_> so if I want my Z axis to move one inch when issued G0 Z1.0
[21:02:00] <barjunk_> but it physically moves it 1.5 inches....where can I change the value to correct that??
[21:02:58] <barjunk_> I'm not using home switches at the moment...if that matters.
[21:03:41] <PetefromTn_> Would'nt that just be your steps per inch settings?
[21:07:41] <barjunk_> Well yes, but that doesn't exist in the ini file as far as I can tell
[21:07:46] <barjunk_> is that the SCALE value?
[21:09:34] <barjunk_> From what I can tell, that looks to be the right thing, but didn't want to mess with it...guess I'll just go try it and see.
[21:09:52] <barjunk_> What could possibly go wrong? :)
[21:10:12] <barjunk_> PetefromTn_ Looks like you got your problem sorted?
[21:15:16] <PetefromTn_> yeah machine is working correctly now I think. Tommorrow I will know better if it forgets everything.
[21:31:13] <barjunk_> That would stink
[21:31:32] <barjunk_> SCALE does seem to impact it, but then there is a point where changing the number doesn't seem to matter.
[21:31:50] <barjunk_> This may have to do with the driver software, so I'm going to check into that now.
[21:32:29] <Tom_itx> PetefromTn_ did you figure out what was wrong?
[21:33:22] <PetefromTn_> Did I manage to get the TLO set correctly yes... did I figure out why it was 71 inches something ....No unfortunately
[21:33:43] <PetefromTn_> I managed to make three successful runs of that prototype part I was machining without incident.
[21:33:46] <barjunk_> I just hope you don't have to reset it again...
[21:33:55] <barjunk_> That's good.
[21:34:18] <PetefromTn_> Parts came out to spec and look great so I am happy for now LOL
[21:34:46] <PetefromTn_> Gotta program some sacrificial jaws and cut the second side.
[21:50:44] <furrywolf> http://lostcoastoutpost.com/2015/may/23/photos-2015-kinetic-grand-championship-sculpture-f/ why doesn't everywhere have one of these? :)
[22:37:41] <barjunk_> PetefromTn_, mine is working out as well...still a little more calibration, but I'm getting closer.
[22:37:52] <PetefromTn_> excellent glad to hear it.
[22:38:09] <barjunk_> I'm building a foam cutter out of an old HP plotter and an Arduino.
[22:38:17] <barjunk_> It has been an interesting experience.
[22:38:39] <barjunk_> cuts 6mm foam to make foam rc plane parts.
[22:41:01] <furrywolf> sounds like a good excuse to build a laser table
[22:42:38] <barjunk_> this seemed like a simpler first step to my limited knowledgebase
[22:43:03] <cradek> whee, I'm successfully making dia 0.045, 90 tpi flat head screws
[22:43:39] <barjunk_> one of my criteria was that I could move the unit by myself...the plotter platform has wheels.
[22:44:04] <furrywolf> cradek: making something very, very little? or just testing machine?
[22:44:07] <barjunk_> And that I could move it out of the way in the garage without having to man handle it.
[22:44:40] <barjunk_> foam is 2ft, by 4ft lengths.
[22:45:01] <cradek> furrywolf: screws for some very old glasses
[22:49:27] <furrywolf> I need to build a spindle encoder, but I need a mesa board first.
[22:50:39] <Tom_itx> cradek did it fit ok?
[22:50:46] <Tom_itx> mating part not too worn?
[22:52:23] <furrywolf> if it is, you can make the screws oversized...
[22:53:23] <cradek> Tom_itx: they work great
[22:53:36] <cradek> I have to finish the heads in a second op
[22:53:46] <cradek> I have a watchmakers lathe with collets that will be perfect for that
[23:00:55] <cradek> my parting tool is a jeweler's saw :-)
[23:01:55] <furrywolf> I don't think either of my lathes could accurately make a part like that without a lot of fine tweaking.
[23:02:34] <furrywolf> the sherline is worn, and the shoptask came that way new.
[23:02:59] <cradek> this is just on my sherline, no tweaking except very carefully ground tools
[23:03:21] <cradek> the threading tool used to be a parting tool
[23:04:11] <furrywolf> I made my last batch of tools from broken drillbits, because they were handy. somehow I have an infinite supply of them...
[23:04:20] <cradek> haha yep
[23:05:16] <barjunk_> Is there a command that sends everything back to home?
[23:05:28] <furrywolf> I can't do any threading until I build a spindle encoder, and I can't connect a spindle encoder until I set up a mesa system, and I can't get a mesa system until I magically develop a spare $200...
[23:05:29] <barjunk_> Maybe something like G0 X0Y0
[23:05:31] <barjunk_> ?
[23:05:32] <cradek> you might want g0 g53 x0 y0 z0
[23:05:50] <barjunk_> ok.
[23:05:55] <cradek> you should also read the docs about g28, g28.1, g30, g30.1
[23:06:06] <barjunk_> OK...thanks.
[23:06:10] <cradek> (they may or may not be what you want)
[23:06:15] <furrywolf> I'm paranoid and home z first, but I'm mostly incompetent...
[23:06:35] <barjunk_> I'll fiddle some more...thanks.
[23:07:06] <cradek> furrywolf: touchy has a "go all the way up" button which is really nice
[23:07:40] <cradek> it's just like a full speed jog all the way to the top of travel
[23:17:32] <furrywolf> I've never looked at touchy... rtfming now.
[23:18:49] <cradek> it's awesome
[23:19:12] <furrywolf> I can't use my touchscreen until I get the mesa board, and a jog wheel is a spare-time-and-money part. heh.
[23:20:27] <cradek> http://timeguy.com/cradek-files/emc/ao-screws-firstop.jpg
[23:20:50] <cradek> the bottom one is the thread sample
[23:21:17] <furrywolf> shiny
[23:22:53] <cradek> they'll be super easy to grab in a WW collet to finish up
[23:22:57] <PetefromTn_> ooh pretty!
[23:23:12] <cradek> but I have to take the spindle encoder off to use the collets :-/
[23:23:22] <cradek> some day I'll make a new drawtube to avoid that
[23:24:48] <cradek> heh I should mount the screwhead file on the sherline and have it do the slots too
[23:24:55] <cradek> that's be funny
[23:24:57] <cradek> that'd
[23:26:40] <furrywolf> I want to use my mill to cut keyways... planning on just sticking a cutter in the spindle, finding a way to lock it, and abusing my Z axis for a while.
[23:27:34] <cradek> that's sure been done before...
[23:28:16] <furrywolf> very similar to using a file for screwheads. :)
[23:28:29] <cradek> hey now you have an excuse to buy a shaper
[23:28:40] <cradek> yep same idea, but much bigger...
[23:28:53] <furrywolf> buying things requires money and space
[23:29:43] <cradek> and space costs money
[23:29:47] <furrywolf> yep
[23:30:49] <furrywolf> first use of money, should it become available, is the mesa board.
[23:32:10] <furrywolf> current project is building the enclosure... I got the metal cut, now need to drill and screw. but, the sculpture race has taken priority.
[23:38:16] <furrywolf> 6 plates, 11 angles, 2 piano hinges.
[23:38:46] <furrywolf> I might need heavier-duty hinges... the only ones the local stores carry (and they all carry the exact same ones, because there's only one distributor in the entire area it seems) are exceedingly flimsy.
[23:50:17] <XXCoderMint> heys
[23:51:58] <furrywolf> changed your flavor today?
[23:53:32] <XXCoderMint> installing mint on new pc
[23:53:40] <XXCoderMint> having issues so far
[23:53:48] <XXCoderMint> installer crashes :(
[23:54:09] <furrywolf> lol
[23:54:44] <furrywolf> only installers I've had crash were windows and beos.
[23:55:35] <XXCoderMint> I dont think my flash drive is any good
[23:55:42] <XXCoderMint> and new pc has no cd drive lol
