12:23 AM Crom: oops
12:41 AM samy^: Does anyone use a grbl based system and *want* to use Inventable's Easel with it? I've ported it and would love to test
12:49 AM CaptHindsight: I'm waiting for a cnc controller written in cobol
12:50 AM samy^: makes sense
12:50 AM CaptHindsight: I mean business
12:51 AM samy^: it's business time
12:53 AM Crom: hmmm... need to look through my junk and find a switch that wirks
01:02 AM Crom: works
01:25 AM IchGucksLive: morning from Germany
01:26 AM IchGucksLive: Europ awakes to a sunny summer day ecept UK ;-) they went out on weathere 2
01:27 AM roycroft: 'morgen
01:28 AM IchGucksLive: off to school til later
01:33 AM LeelooMinai: Heh, finally got that NativeCAM working fine - that was a painful time.
01:34 AM LeelooMinai: Time to go to sleep - the good news is that seems the orange person won't survive a lot longer:)
01:36 AM Deejay: moin
05:21 AM jthornton: morning
05:21 AM XXCoder: yo
05:25 AM jthornton: I ordered a eagle tree vector flight controller for my hex
05:25 AM jthornton: that seems to do more what I want to do
05:26 AM XXCoder: how so?
05:27 AM jthornton: https://www.youtube.com/watch?v=6aRe948EKYs
05:28 AM jthornton: it has loiter and return to home and land
05:29 AM XXCoder: im sure other controller has "arrest loiters" feature. ;)
05:31 AM jthornton: the seppuku that I have in the tweaker does not seem to have any of that
05:31 AM jthornton: https://www.youtube.com/watch?v=3rB_5cJLjLY
05:33 AM jthornton: the vector has gps and on screen display
05:33 AM jthornton: http://www.eagletreesystems.com/index.php?route=product/product&product_id=136
05:34 AM jthornton: basically it has all the stuff you have to add into a regular flight controller
05:53 AM XXCoder: jthornton: did you see the lego plane flight?
05:53 AM XXCoder: pretty cool.
05:53 AM XXCoder: real flight. giant fake lego plane
05:53 AM XXCoder: https://www.youtube.com/watch?v=JmyJeo4Ewpk
05:53 AM jthornton: yea, that was pretty cool that lego acknowledged him
05:53 AM XXCoder: indeed
05:56 AM XXCoder: also cool https://www.youtube.com/watch?v=bziR-qsCUFQ
05:56 AM XXCoder: f-zerpo
05:57 AM XXCoder: with more and more fpv I wonder if racing could be done
05:57 AM XXCoder: I would design a FULL driving rig
05:57 AM XXCoder: not hand control
06:07 AM XXCoder: jthornton: check this out http://www.omc-stepperonline.com/high-torque-nema-23-cnc-stepper-motor-113mm-3nm425ozin-23hs454204s-p-127.html
06:07 AM XXCoder: maybe future upgrade for my machine! surpising cheap
06:07 AM jthornton: that's a big one
06:08 AM XXCoder: and my psu wouldnt be able to supply it lol
06:08 AM XXCoder: 4.2a each lol
06:12 AM Tom_L: 10mm shaft size
06:13 AM Tom_L: i thought most nema23 were 1/4"
06:15 AM Tom_L: JT-Shop, do you recall what GUI you used with debian?
06:15 AM jthornton: didn't use debian enough to recall
06:16 AM Tom_L: started working on getting this box back up
06:25 AM jthornton: I use mate desktop on my linux mint machines
06:26 AM XXCoder: xfce is my go to
06:27 AM jthornton: I wonder how long it will take for the first chick to leave the coop this morning, opened the door 15 minutes ago
08:15 AM tommylight: ???????????
08:16 AM archivist_herron: you will find a real question works better than ?????
08:17 AM tommylight: oh good, just checking
08:17 AM JT-Shop: check failed
08:18 AM tommylight: lol yup monumentaly
08:19 AM tommylight: How are you people doing
08:19 AM JT-Shop: I'm doing good
08:19 AM tommylight: nicglad to know
08:19 AM tommylight: how is the busines going bro?
08:22 AM JT-Shop: not bad actually making a bit of money this year mostly programming PLC's
08:24 AM JT-Shop: I have to drive to Cuba tomorrow and install a key switch and a couple of proxes
08:24 AM JT-Shop: 3 hrs each way with all crooked roads
08:47 AM skunkworks: JT-Shop, what did you end up wit for a 3d printer?
08:49 AM JT-Shop: https://www.aliexpress.com/item/full-metal-frame-best-price-3d-printer-kit/32262897404.html
08:55 AM skunkworks: Do you like it?
08:56 AM JT-Shop: It's ok, I had to "fix" a few things on it and the controller board died
08:57 AM JT-Shop: this one looks better but twice the price https://www.aliexpress.com/item/New-Arrive-3D-printer-I3-Mega-full-metal-color-quasi-industrial-grade-high-precision/32767583851.html
09:08 AM JT-Shop: skunkworks: XXCoder and one other that I know of have the same printer
09:22 AM tommylight: sorry was bussy moving the MAZAK a bit to the side
09:23 AM tommylight: back in half hour
09:32 AM archivist_herron: damned flaky network here today
09:57 AM LeelooMinai: Hmm, had a coupler on X axis not tightened properly and during a test the stage kept being offset to one side:) But that made me realize that better place for encoders would be at the end of ballscrew really, not behind the stepper - but they would need to be somehow fit behind the end block and attached without screw (epoxy maybe)?
09:58 AM LeelooMinai: And would need to be smaller.
10:02 AM codepython777: I need to get some carbon fiber cut - anyone can recommend a shop that would do this for me? I am looking for a quote.
10:02 AM LeelooMinai: codepython777: I have a small piece - I can cut you with it for free:)
10:06 AM codepython777: LeelooMinai: are you in the US?
10:06 AM LeelooMinai: No, Canada (fortunatelly)
10:07 AM DaViruz: the nonunited state
10:08 AM LeelooMinai: Westeros
10:09 AM LeelooMinai: Cold, but far awat from Lanisters:)
10:09 AM archivist_herron: LeelooMinai, couplers to encoders are generally ok
10:10 AM LeelooMinai: archivist_herron: It was the ballscrew-stepper coupler that slipped.
10:10 AM LeelooMinai: But encoder cannot really know that.
10:11 AM LeelooMinai: Which is pretty bad imo - the point of encoder mostly being for verifying the stage does not lose steps, etc.
10:12 AM LeelooMinai: I tightened the coupler of course, cleaned it with WD40 and then with IPA, but still.
10:12 AM DaViruz: put the encoder in the non driving end :)
10:12 AM DaViruz: (of course usually not a very simple task)
10:13 AM LeelooMinai: Well, that's what I wrote - that ideally it should be attached to the ballscrew, but that's a bit problematic, since depending on the CNC, that place may be inaccessible more or less.
10:13 AM DaViruz: oh.
10:13 AM DaViruz: i don't think i've ever had a coupler slip
10:14 AM DaViruz: LeelooMinai: you seem to have a record of not tightening things enough though ;)
10:14 AM archivist_herron: I have had driving couplers slip
10:14 AM codepython777: can anyone recommend me a shop that would cut carbon fiber online? (US)
10:14 AM LeelooMinai: Well, I may have forgotten to tighten it or something - it was done a year ago.
10:15 AM Tom_L: http://www.emachineshop.com/machine-shop/Custom-Carbon-Fiber-Parts/page441.html
10:15 AM Tom_L: https://www.rcgroups.com/forums/showthread.php?1579982-Sources-for-Custom-CNC-Cutting-Carbon-Fiber
10:16 AM Tom_L: https://dragonplate.com/sections/CNC-machined.asp
10:16 AM Tom_L: codepython777, how many do you need?
10:16 AM codepython777: 10 sheets of 12"x12" material cut
10:16 AM Tom_L: links...
10:20 AM Tom_L: pretty sure our local vo-tech can do it too at a hefty fee
10:24 AM Tom_L: http://www.niar.wichita.edu/researchlabs/
10:24 AM LeelooMinai: Hmm, any idea what kind of backslash a normal helical coupler can introduce? And how better a "spider" type one would/can be if any?
10:25 AM Tom_L: spider would probably have alot
10:25 AM LeelooMinai: Hmm, I thought someone here once said that they are better... They cost more.
10:26 AM Tom_L: couldn't say
10:27 AM LeelooMinai: I guess time for "research": https://www.youtube.com/results?search_query=helical+vs+spider+coupler
10:27 AM LeelooMinai: Though probably this will end up with some Trump video distraction on the way.
10:28 AM LeelooMinai: Hmm, they claim there the ones with hard middle have "zero backlash", while softer have some dampening.
10:29 AM archivist_herron: most of the spider couplings have interference fits, so no backlash
10:29 AM LeelooMinai: Maybe someone measured the two in practice on youtube and has some data.
10:30 AM LeelooMinai: They call those "zero backlash oldham-style couplings"
10:33 AM archivist_herron: I use oldham couplings
10:34 AM LeelooMinai: lol, nice intro: http://i.imgur.com/2Wef13w.png
10:35 AM LeelooMinai: archivist_herron: And you think it's worth replacing helical with those for milling?
10:35 AM archivist_herron: helicals have a reputation for breaking
10:36 AM archivist_herron: less able to take misalignment
10:36 AM LeelooMinai: well, if they break, they break, I do not have a heavy-duty factory here. More wondering about that backlsh posibility.
10:38 AM LeelooMinai: If I had a hard coupling, I could maybe do tests and measure the difference.
10:39 AM LeelooMinai: would also know what I have as backlash and how much of it is due to the coupling, etc. - probably a good idea for one day.
10:40 AM archivist_herron: the error of axes of ballscrew and motor alignment means dont use rigid, helical is close to rigid
10:40 AM LeelooMinai: Right, but I meant to use it only for measurement.
10:41 AM LeelooMinai: Or maybe I could just move the ballscrew by hand...
10:41 AM archivist_herron: something too rigid eventually works the grub screws free
10:41 AM LeelooMinai: That would allow me to measure backlash without any coupler influence.
10:42 AM LeelooMinai: I think...
10:44 AM archivist_herron: relevant to this subject and you can see the coupler http://www.archivist.info/cnc/screw_error/
10:45 AM archivist_herron: stepper error swamping mechanical error :)
10:47 AM LeelooMinai: archivist_herron: Would be much nicer if you used and compared different types of couplers there...
10:47 AM LeelooMinai: And a rigid one as a reference.
10:48 AM LeelooMinai: As you had this nice expensive Mutitoyo with logging capability:)
10:52 AM * LeelooMinai opens some package with Chinese connectors and has no idea what those were ordered for by now
10:53 AM jdh: chinese christmas
10:55 AM LeelooMinai: o, but I know what the second package is for:)
10:55 AM roycroft: tomorrow is israeli christmas for me :)
10:55 AM roycroft: except i peeked and know what's in the package already
10:55 AM LeelooMinai: The second package is sweet: https://www.aliexpress.com/item/Free-shipping-One-terminal-box-HSC8-6-4-6-4A-6-4B-6-6-6-6A/32803820664.html?spm=2114.13010608.0.0.N3sXyo
10:56 AM LeelooMinai: I found about those and will use all on the wiring going into the Mesa cards, etc.
10:56 AM roycroft: and it's not a draidel and some geld!
10:57 AM LeelooMinai: roycroft: The what? :p
10:57 AM roycroft: i got a set of that stuff a while ago, leeloominai
10:57 AM roycroft: i've only done a couple test crimps so far, but i'm happy with them
10:57 AM LeelooMinai: That crimper looks pretty jazzy at close look.
10:57 AM roycroft: it's a brilliant way to handle stranded wires that need to be inserted into sockets
10:57 AM roycroft: one should never solder the ends of stranded wires
10:58 AM LeelooMinai: Right, that was my impression, so decided to "invest" into that system.
10:59 AM LeelooMinai: Saw those once on some setup on youtube and thought "hmm, and what are those little buggers"
11:03 AM roycroft: they are like aglets
11:03 AM roycroft: but for copper wires
11:05 AM LeelooMinai: Hmm, the plastic part could be a bit less in diameter - not sure why they are so oversized.
11:05 AM roycroft: some wires have thick insulation
11:05 AM LeelooMinai: I guess for insulation, but wish it was not that big.
11:06 AM LeelooMinai: Yes, but the tiny wires going into the Mesa connectors - they do not exactly have thick insulation, so that collar only will take space.
11:06 AM LeelooMinai: But still should work probably.
11:06 AM LeelooMinai: Maybe the plastic part can be crimped too:p
11:07 AM LeelooMinai: Hmm, ideally it would be heatshrinkable, but probably it's not that funky...
11:08 AM LeelooMinai: That would be awsome - you crimp, heat, and have an ideal end.
11:08 AM tommylight: internet acting up
11:09 AM roycroft: i've seen connectors with heat shrinkable sleeves
11:09 AM roycroft: i've never used them though
11:09 AM tommylight: lol nice one
11:09 AM roycroft: when i need to do that i use bare connectors and put my own heat shrink tubing over them
11:09 AM roycroft: that's required for doing power and data cabling in carrier class facilities
11:10 AM roycroft: also, the crimp lugs need to have inspection windows when used in those facilities
11:10 AM roycroft: and the crimp dies need to emboss the die size on the lug
11:10 AM LeelooMinai: Right, I have all the electronics "gear", including oscilloscope, microscope for inspection, etc., so tons of heatshrink tubes also.
11:11 AM LeelooMinai: Just thhought that integrated one would be very convenient.
11:11 AM roycroft: i picked up an old panduit heat shrink tubing retail display at the goodwill a while back
11:11 AM roycroft: so i have a nice, neat way to organize my heat shrink tubing
11:11 AM LeelooMinai: I guess I will try heating one of those later for lols, who knows:)
11:12 AM LeelooMinai: At worst it will melt.
11:12 AM roycroft: no
11:12 AM roycroft: at worst it will burst into flames and burn your house down
11:12 AM roycroft: or at the very least singe your hair
11:13 AM LeelooMinai: That's very pessimistic...
11:13 AM roycroft: you are the one who brought up worst case scenarios
11:14 AM LeelooMinai: But, not sure if it was here, I think here, someone, a woman, I think burned part of the house because she went to open a door to get a package and in the meantime the laser cutter got on fire:)
11:14 AM LeelooMinai: But I think the damage done by firefighters with water was bigger than the fire itself...
11:15 AM roycroft: i vaguely recall hearing about that
11:15 AM LeelooMinai: I guess thing to consider when calling the fire department...
11:16 AM LeelooMinai: That's me imagining firefighters hosing my room with water: http://www.impawards.com/1990/posters/home_alone_ver1.jpg
11:17 AM LeelooMinai: I wonder if one can sue them:)
11:27 AM djdelorie: LeelooMinai: the damage done by the water is usually less than the damage done by an *unchecked* fire, though.
11:28 AM LeelooMinai: Right, if it spreads, sure.
11:28 AM * djdelorie has an automatic fire sprinkler system
11:29 AM LeelooMinai: Well, I don't know about that one... what if you are out and it goes on erroreounously?
11:29 AM LeelooMinai: error-somethign
11:29 AM LeelooMinai: errorenously:)
11:30 AM LeelooMinai: I have CO detector in my bedroom, and normal fire ones, and small extinguisher on the wall in my room too, just in case:)
11:34 AM LeelooMinai: Hmm, took 15 minutes to dig in the aliexpress history to find out what my ballscrews are finished to in diameter at the end, and then when I could not get the info, 30 seconds to get up and measure it will callipers - typical.
11:41 AM djdelorie: LeelooMinai: the only way they go off is if it gets hot enough to melt the cap off. Then they spray the room with water and call the fire department.
11:42 AM LeelooMinai: Ok, never really saw how they are cconstructed.
11:45 AM djdelorie: or boil a glass vial until it bursts, I don't know exactly what mine have
11:46 AM djdelorie: they're just little dots on the ceiling
11:49 AM LeelooMinai: Right, jsust read about the vial with alcohol that shatters and opens a valve - neat.
11:49 AM LeelooMinai: Simple, but reliable and needs no energy or anything.
11:50 AM djdelorie: but I also have a flow sensor in the feed line, which triggers the alarm system, which eventually calls the fire department
11:51 AM LeelooMinai: When I was small I made something similar to scare my religious grandmother. I attached a little monster figure holding a reversed cross to a rubber band, and then put it on top the lamp and fixed it to the light bulb with wax - so when she came home and turned on the lights, after a while the wax melted and the monster "bungie jumped" from the ceiling.
11:57 AM archivist: LeelooMinai, the logging was pen and paper and then typing into the data base
11:58 AM LeelooMinai: archivist_herron: I see a data transfer cable attached to it...
11:58 AM archivist: power cable
11:58 AM LeelooMinai: Pff
11:59 AM JT-Shop: lol
11:59 AM archivist: LeelooMinai, oh I had not noticed that was a practice "does this fit" data cable was not going anywhere
12:01 PM archivist: never got around to doing anything with the logging
12:01 PM LeelooMinai: archivist_herron: I REed the protocol (not that it is complicated - just bits of data and clock at about I think 8 Hz or so,) of the Chinese calippers and digital indicators I have around, and even made a board with FPGA (I know, not needed, but just for OCD-factor,) to decode it and pass onto modbus.
12:02 PM archivist: these days I may use a fartuino to grab it
12:02 PM LeelooMinai: Then got distraccted with something as always, and lamely now I don't have it working at hand.
12:02 PM LeelooMinai: Right, I have the timings in a spreadsheet somewhere - any micro can decode it easily.
12:03 PM LeelooMinai: The problem was the connector - tracked some down eventually, but they are kind of unobtanium.
12:04 PM archivist: the cables are on ebay often enough but at silly prices
12:05 PM LeelooMinai: Not sure if you remember, but I got two of those digital weird short prototypes of indicators from one place one just because the custom cables were in the package - the whole thing was $8.
12:06 PM LeelooMinai: But maybe now they sell those cables somewhere at a premium - it was long time ago.
12:15 PM archivist: £10 to £45 for mitutoyo cables today on ebay
12:16 PM LeelooMinai: Hmm, the question is if they are same as in all those chinese callipers/indicators - that is if Chinese basically copied them from Mutitoyo.
12:16 PM archivist: but as you can see from my picture it is a standard IDC
12:17 PM archivist: the calipers uses something different to the dial inticator
12:17 PM LeelooMinai: Right, so no - the ones I am talking about are 4 pads - kind of like USB, but different spacing and the connector I got had a rather weird shape and looked like someone made mold for some low volume production,
12:18 PM LeelooMinai: Well, not mine - my 1 micron digital "dial" indicator uses the same connector as the callipers.
12:20 PM LeelooMinai: I will make a pic
12:20 PM archivist: the mitutoyo I have here is 5 pads
12:25 PM IchGucksLive: hi
12:25 PM LeelooMinai: archivist_herron: Here, found it finally in one of my boxes: https://www.flickr.com/photos/100017731@N03/33876526464/in/dateposted-public/
12:25 PM LeelooMinai: A weird bugger:)
12:28 PM archivist: flikr refuses to show me images
12:28 PM LeelooMinai: Hmm, how about here: http://i.imgur.com/agYrQB9.jpg
12:29 PM archivist: imgur is ok and sane
12:29 PM archivist: odd that there are 4 and 5 pin versions
12:30 PM LeelooMinai: Well, not that sane, since that's where first I had images and it had limit and ate old ones at some point:/
12:30 PM archivist: I self host so dont have problems
12:30 PM LeelooMinai: But Mutitoyo probably has own standards.
12:31 PM LeelooMinai: From what I have seen most Chinese ones stick to this connector I have.
12:31 PM LeelooMinai: The indicator I have is "Shahe" brand, whatever they are:)
12:36 PM LeelooMinai: Looks like that: https://www.aliexpress.com/item/High-Accuracy-0-25-4mm-1-Electronic-Indicator-Gauge-0-001mm-0-00005-Digital-Dial-Indicator/32493429400.html
12:40 PM * roycroft also self hosts, and never has the problems that the cloudy people have
12:41 PM archivist: hehe # Max Measuring Range: 11- 29mm
12:42 PM LeelooMinai: Probably meant something else, like -11 to 28 or different models:)
12:44 PM archivist: might be how much the plunger sticks out
12:46 PM LeelooMinai: The sellers there are not known for providing best documentation in general:) But it's a bit better than years ago I noticed. I even saw that for some products they have little videos embeded with commercials for them where they dubbed a properly english speaking voice on top:)
01:00 PM Crom: Morning all
01:04 PM IchGucksLive: good evening sir
01:22 PM gregcnc: I've never seen an omniturn on an HSL-59. I have considered building something like this. http://www.ebay.com/itm/311873811304
01:32 PM LeelooMinai: "Chína Plans Giant Worldwide Green Energy Revolutíon". "pledged to spend $900 billion on infrastructure abroad" <- weird how times have changed:)
01:32 PM Jymmm: Curious, why would one choose ruby over (let's say) chromium tipped ?
01:33 PM LeelooMinai: Maybe has something to do with "sticking" that can occur with some material combinations?
01:34 PM LeelooMinai: Jymmm: Some good info here: http://www.renishaw.com/en/materials--6423
01:35 PM LeelooMinai: I bought two ruby styli from aliexpress - plan to use them in my probe, if I ever finish it.
01:36 PM LeelooMinai: Were $8 or so - not too bad.
01:37 PM LeelooMinai: Hmm, though now when I read that page, thay say that for aluminum probing silicon nitride is better. I have some ceramic balls from aliexpress to though:)
01:38 PM Jymmm: LeelooMinai: Maybe, not sure. I know that some touch probe use ruby tipped probes. I have a trackball that uses three ruby balls to roll/rest the ball upon, and when it's new, it's like water on glass. But after a year or so, even with cleaning, it becomes more like a light syrup on glass at times.
01:40 PM LeelooMinai: Well, but the ball probably wears off to - and it's surely not made from big ruby...
01:40 PM Jymmm: I don't see any wear on the ball or rubys, I can only sumize that the plastic base that holds the rubys is slightly deforming
01:41 PM Loetmichel_: LeelooMinai: usually it IS made of (synthetic) ruby
01:41 PM Loetmichel_: and doesent wear off that much
01:41 PM Jymmm: or maybe the cups that hodl the rubys are deforming ever so slightly
01:41 PM LeelooMinai: From what they write, the main point is that ruby is super-hard, like diamond I guess, so it's superior unless there's some interaction with specific material, like aluminum.
01:41 PM LeelooMinai: Loetmichel_: The trackball?
01:41 PM IchGucksLive: LeelooMinai: on china its warren buffet powerde
01:41 PM CaptHindsight: Jymmm: pretty sure in your case it's due to Gremlins
01:42 PM Loetmichel_: no, the tips of "pupitast" and similar measurement tools
01:42 PM Jymmm: CaptHindsight: Nah, I don't feed them after midnight
01:42 PM LeelooMinai: Loetmichel_: Right, but he was talking about his trackball:)
01:42 PM Jymmm: Kensington Slimblade
01:42 PM LeelooMinai: 1 inch diamter ruby, synthetic or not - I don't think so:)
01:42 PM Jymmm: Kensington Slimblade trackball
01:42 PM Loetmichel_: if that has ruby bearings than the ball is most likely made of hardened steel or glass
01:43 PM SpeedEvil: LeelooMinai: well, I have a 20mm or so diameter sapphire cylinder
01:43 PM IchGucksLive: LeelooMinai: somthing like that https://www.sorotec.de/shop/CNC-Zubehoer/taster/3d-messtaster/
01:44 PM SpeedEvil: LeelooMinai: It was quite cheap - I meant to make a torch out of it - but have not gotten round to it
01:44 PM IchGucksLive: 3D finder
01:44 PM LeelooMinai: I know, I am designing mine, because cannot afford them.
01:44 PM Jymmm: Loetmichel_: Not steel
01:44 PM IchGucksLive: agree
01:45 PM Loetmichel_: Jymmm: glass then?
01:45 PM IchGucksLive: glass perls are realy cheep
01:45 PM IchGucksLive: in hobby stores
01:45 PM Loetmichel_: because if its made of resin its no wonder it starts to stick after a while if it has ruby glide pads ;)
01:45 PM Jymmm: Loetmichel_: I honestly dont believe so.
01:45 PM IchGucksLive: ok im off
01:46 PM IchGucksLive: Gn8 from Germany
01:46 PM Loetmichel_: would be a classic fail in material pairing
01:46 PM LeelooMinai: It's made of a piece of Sauron's eye
01:46 PM Jymmm: Loetmichel_: Eh, no clue. I have a 4th one coming under warranty replacement *shrug*
01:47 PM LeelooMinai: lol
01:47 PM * Loetmichel_ hat some industrial trackball with a 1.5" polished Stainless steel ball and ruby glide pads
01:47 PM LeelooMinai: Jymmm: You have some good plan going there:)
01:47 PM Loetmichel_: MAAAN was that thing good
01:47 PM Loetmichel_: one push and it would turn for 30 seconds ;)
01:48 PM LeelooMinai: I saw some company selling industrial trackball units - was even thinking of getting one for CAD, but was expensive.
01:48 PM Jymmm: LeelooMinai: LOL, thanks. But this will be the last under warranty.
01:48 PM Loetmichel_: but the price tag was a bit "over the top" (may have something to do with the mil-std-810 certification on it ;)
01:48 PM Jymmm: Theball has a sparly/glittery surface (optical reflector), or I'd LOVE to use a solid steel ball
01:48 PM LeelooMinai: Then there are those 3D Navigators or what they are, but the cheapest one is also $130 or so.
01:49 PM roycroft: are you talking about a 3d mouse, leeloominai?
01:49 PM Jymmm: LeelooMinai: 3dconnex aren't actually "mice" though, that being the issue.
01:49 PM Loetmichel_: Jymmm: they can act as such though
01:49 PM roycroft: no, they can't
01:49 PM roycroft: they work in conjunction with a mouse
01:49 PM LeelooMinai: Right, the connex things - they are for rotating things in 3D space as I understand.
01:49 PM roycroft: and they can be had used on ebay for ~$50
01:50 PM roycroft: and are worth every penny
01:50 PM Jymmm: LeelooMinai: Eh, not really. I've played with acouple, you need a mouse too
01:50 PM Loetmichel_: roycroft: i had one, you can configure it to have 2 axis as mouse contrlos
01:50 PM LeelooMinai: THough by now I kind of learned rotating with mouse so well, that not sure if that would be worth the money.
01:50 PM roycroft: i guarantee it's worth the money
01:50 PM roycroft: i can make assemblies in solidworks 10x faster with the 3d mouse than before i had it
01:51 PM Loetmichel_: i once used it to fly a quadcopter... works well, too, after a bit of getting used to
01:51 PM LeelooMinai: roycroft: RIght, make me spend more money on gadgets - great idea:p
01:51 PM Loetmichel_: is funny tho if you are out there with a big ass 3dmouse and a laptop to contol a little copter ;)
01:51 PM roycroft: you zoom, rotate, and revolve with the 3d mouse
01:51 PM roycroft: and select/mate/etc. with the regular mose
01:52 PM LeelooMinai: roycroft: Did you see my computing "station"? :)
01:52 PM Loetmichel_: roycroft: you CAN map the 3dmouses axis to nearly anything you like
01:52 PM roycroft: no
01:52 PM roycroft: and i'm not making you do anything
01:52 PM roycroft: i'm just giving you information :)
01:53 PM LeelooMinai: Lies - now I have stuck in my head "maybe I need this thing"
01:53 PM roycroft: and i'm actually saving you money
01:53 PM roycroft: you were talking about spending $100+ on one
01:53 PM Loetmichel_: LeelooMinai: its fun to use and its a great enhancement when you are doing 3dcad all day
01:53 PM roycroft: and i told you you can get it for half that
01:53 PM LeelooMinai: roycroft: Mycomputing corner looks like that: https://www.flickr.com/photos/100017731@N03/24655172365/in/dateposted-public/ :)
01:53 PM Loetmichel_: i wont say its NECCESSARY though
01:54 PM roycroft: looks crowded, but comfy
01:54 PM Loetmichel_: LeelooMinai: that chair... :-)
01:54 PM LeelooMinai: And you want me to add one more gadget:p
01:55 PM roycroft: i would say it is necessary in a commercial cad house
01:55 PM LeelooMinai: Loetmichel_: I know, looks funny, but it's the most comfortable chair ever and made it from $60 one - and it solved back pain problems like magic.
01:55 PM roycroft: it's such a productivity boost that it should be required there
01:55 PM roycroft: for a hobbyist or a small shop, not so much
01:55 PM Loetmichel_: LeelooMinai: i am already thru my fourth desk chair at home...
01:56 PM Loetmichel_: most of them ended up like that: http://www.cyrom.org/palbum/main.php?g2_itemId=15392
01:56 PM Loetmichel_: ... maybe i should go on a diet ;)
01:56 PM LeelooMinai: Right, at one point I got mad and stopped buying those "normal" office ones - imo they are deadly for the spine.
01:57 PM roycroft: too much schnitzel and strudel
01:57 PM LeelooMinai: Loetmichel_: lol, ok, mine did not do that, but after 4 hours of sitting I was fealing like someone tortured me.
01:57 PM Jymmm: Loetmichel_: get one of these, at least you can reapir it easily https://s-media-cache-ak0.pinimg.com/736x/91/6e/33/916e3342b21dc77a30d6677ee341ce1a.jpg
01:57 PM Loetmichel_: roycroft: my wife gifted me a t-shirt with "HUNGER! someone peel me a cow!"
01:57 PM Loetmichel_: any questions?
01:57 PM LeelooMinai: Jymmm: Great idea - $10 chair and $10k bill for the spine surgery:)
01:58 PM Loetmichel_: Jymmm: i need wheels on it
01:58 PM Jymmm: LeelooMinai: Why? I have/use a wooden chair
01:58 PM Loetmichel_: the seat is actually better in hard
01:58 PM Jymmm: Loetmichel_: Thenput wheels on it
01:59 PM LeelooMinai: Jymmm: Well, it also depends how many hours per day you sit on it...
01:59 PM Loetmichel_: Jymmm: then THAT happens: http://www.cyrom.org/palbum/main.php?g2_itemId=14603&g2_imageViewsIndex=1
01:59 PM roycroft: so when i was reassembling my lathe last night it was obvious that it had never been mounted on the ship pan with the motor that came with it
01:59 PM Loetmichel_: (at the company, was a cheap one though)
01:59 PM Jymmm: Loetmichel_: put REAL csters on it
01:59 PM LeelooMinai: Loetmichel_: They should hire you as a stress tester at a chair-making company:p
01:59 PM roycroft: the chip pan rim interfered with the electrics connector box
02:00 PM roycroft: and i had to slit a section of the rim and bend it down in order to get it to fit
02:00 PM Jymmm: Loetmichel_: I only get chairs fromt he thrift store now, why too expensive otherwise
02:00 PM Loetmichel_: LeelooMinai: may have to do something with my slight overweight
02:00 PM roycroft: that made me sad, as i had just built the stand and painted it up nicely
02:00 PM roycroft: and i'm going to replace that motor anyway
02:00 PM Jymmm: Loetmichel_: plus they've already been thru hell and back... use testing =)
02:00 PM roycroft: as soon as i can afford a 3 phase motor
02:01 PM * LeelooMinai imagines an engineer presenting his new chair desing, then seeing Loetmichel_ approaching to do the test and running away saying "I need to make some modifications!"
02:02 PM DaViruz: that's not a very nice thing to say
02:02 PM Loetmichel_: Jymmm: actually i will soon re-weld the broken off lift base of this one: because otherwise its the most comfortable chair i ever had: http://www.cyrom.org/palbum/main.php?g2_itemId=16173&g2_imageViewsIndex=1
02:02 PM Jymmm: Loetmichel_: I say make the pipe chir
02:02 PM LeelooMinai: DaViruz: Well, I am just judging by the pictures of those broken chairs:)
02:03 PM * Jymmm duct tapes LeelooMinai to the wall
02:03 PM Loetmichel_: LeelooMinai: i am at 125kg at the moment. but i tend to be not tooo careful when "plummeting" into the desk chair after a days work...
02:03 PM DaViruz: to be honest i think that has a lot to do with chair quality as well. i've broken a few crappy ones, and i'm thin as a stick
02:03 PM LeelooMinai: It's not like I am saying that he should by two base plates for the CNC - one for the machine, and one for the operator to stand on:)
02:04 PM Jymmm: LeelooMinai: NO DUCKY FOR YOU!!! http://i.dailymail.co.uk/i/pix/2010/09/21/article-1314000-0B4A3C21000005DC-532_468x332.jpg
02:05 PM Loetmichel_: especially the welds of the "gas ram catch" on the cheap chairs seem not to be made for european or american bodys
02:05 PM Loetmichel_: more like chinese ones ;)
02:06 PM Loetmichel_: had a hard time finding a desk chair a the local Stapels thats rated 130kg...
02:06 PM LeelooMinai: Jymmm: Is that your picture when you were young? :)
02:06 PM Loetmichel_: most are 80kg only
02:06 PM Loetmichel_: i dont even try those, to risky ;)
02:07 PM Jymmm: LeelooMinai: No, that's going to be you
02:07 PM LeelooMinai: I modelled my chair position on this one more or less:) https://s-media-cache-ak0.pinimg.com/originals/f9/3f/24/f93f2413fc33891dee7141a210e2c35b.jpg
02:08 PM LeelooMinai: Or on a dentist chair I guess.
02:08 PM Loetmichel_: you being female another kind of chair comes to mind...
02:09 PM Loetmichel_: ... bad Loetmichel_...
02:09 PM Loetmichel_: :-)
02:09 PM Loetmichel_: ... dirty mind :)
02:09 PM Jymmm: Loetmichel_: pink chair?
02:09 PM Jymmm: Loetmichel_: you know you secretly want a pink chair
02:09 PM Loetmichel_: not really
02:10 PM Jymmm: uh uh
02:10 PM Loetmichel_: more the kind with the stainless stirrups ;)
02:10 PM Jymmm: Loetmichel_: Fine, you can model it for us
02:10 PM LeelooMinai: Pink looks bad when stained with oils, etc.
02:11 PM LeelooMinai: Loetmichel_: Should become ginecologist instead of a machinist then.
02:12 PM LeelooMinai: Ok, staring at a video called "Crushing Crystal Balls with Hydraulic Press - in 4K Slow Motion" is a good sign that I should do something more practical.
02:13 PM LeelooMinai: Like eat dinner.
02:13 PM Jymmm: Yeah, Loetmichel_ as a ob/gyn would be great, he can deal with all the screaming babies non-stop!
02:13 PM Jymmm: and UTI's etc
02:14 PM gregcnc: imagine the work related injuries
02:14 PM Jymmm: lmao
02:14 PM Jymmm: gregcnc++
02:22 PM Loetmichel_: gregcnc: not my trade... would be ready for an insane asylum in less than a week
02:22 PM Jymmm: Loetmichel_: Heh, I give you 42 minutes =)
02:23 PM Loetmichel_: Jymmm: could as well be only 40 minutes, correct ;)
02:23 PM FinboySlick: You guys think they understood the whole lesson? https://pbs.twimg.com/media/C-hysSNXcAAF6eq.jpg:large
02:23 PM Loetmichel_: FinboySlick: could be ;)
02:24 PM Loetmichel_: looking quite attentive at least ;)
02:26 PM FinboySlick: It's for the next Sam L. Jackson movie, for when they get to actually *pilot* the plane.
02:35 PM nubcake_ is now known as nubcake
04:01 PM MacGalempsy: yo
04:10 PM Bact_: can someone help me with a sauter turret hal problem?
04:25 PM Deejay: gn8
04:47 PM MacGalempsy: Bact_ like what?
04:48 PM MacGalempsy: ioh he left
05:38 PM TurBoss: hello
05:38 PM TurBoss: SUP
05:39 PM Cromaglious_: at the makerspace... http://creatorspace.us
05:39 PM TurBoss: Ohhh
05:39 PM Cromaglious_: looks like we have sewing going on tonight
05:43 PM Cromaglious_: I'd love to linuxcnc my straight stitch at home chuck up some leather and let the machine poke holes on all the cut lines...
05:46 PM Cromaglious_: hmmm.... firing up fusion 360 for some fun
05:51 PM Cromaglious_: fun part would be interfacing with the Consew csm1001 'servo' motor
06:02 PM JT-Shop: MacGalempsy:
06:02 PM MacGalempsy: hola
06:02 PM TurBoss: Hola
06:03 PM JT-Shop: I went with Eagle Tree Vector with built in GPS, compass, and OSD for the Tarot 680 pro
06:03 PM JT-Shop: bbl
06:17 PM tommylight: sorry was reading something on the forum, forgot i was loged here
06:47 PM JT-Shop: MacGalempsy: my take on dronin is it's for racing drones mostly
06:47 PM JT-Shop: what's your thoughts?
06:48 PM MacGalempsy: havent got a drone yet. trying to save $. every time i turn around something else comes up
06:49 PM JT-Shop: I hear that
06:50 PM MacGalempsy: may have an opportunity to start another company doing work in ohio
06:50 PM JT-Shop: cool, what kind of company?
06:52 PM MacGalempsy: geology services. sample and gas logging / well steering
06:52 PM JT-Shop: cool
06:52 PM MacGalempsy: it may work out, still trying to get a friend to give me some numbers
06:53 PM MacGalempsy: so i can estimate if we can put in a lower bid to try to get in
07:02 PM MacGalempsy: wb
07:07 PM MacGalempsy: JT-Shop what drone OS are you going to try next?
07:08 PM JT-Shop: on the Taranis 680 Eagle Sky Vector
07:08 PM JT-Shop: might get an Eagle Tree (not sky) Vector Mini for the quad
07:08 PM JT-Shop: lol Eagle Sky is a youth camp I've worked at lol
07:09 PM JT-Shop: hmm hear a lot of racket at the chicken palace brb
07:09 PM MacGalempsy: interesting.
07:11 PM JT-Shop: the Q100 had cleanflight on it and the Tweaker with dronin is more stable
07:11 PM JT-Shop: the Vector has loiter mode which is what I really want I think
07:12 PM JT-Shop: anyhow time for me to retire for the night
07:12 PM MacGalempsy: have u tried taulabs?
07:12 PM JT-Shop: talk to you later
07:12 PM MacGalempsy: bye
08:00 PM dioz: JT-Shop: sup?
08:01 PM dioz: how do i control my pool stick welding 14 gauge?
08:01 PM dioz: hahahahahaha
08:01 PM dioz: i'm eating cheap pizza.
08:02 PM dioz: china is saying 900 million investment into cleaner energy?
08:02 PM LeelooMinai: Yes, and that's just in goreign countries:)
08:02 PM LeelooMinai: foreign*
08:03 PM LeelooMinai: IN the meantime US slaughter all the programs, and go with coal again.
08:08 PM LeelooMinai: Hmm, had an idea to make my cnc stand more rigid by cladding it with steel pegboards, but those things are strangely expensive:/
08:09 PM LeelooMinai: I have PC under there, so that would provide ventilation + a way to hand different tools, shelves, etc. as a bonus.
08:09 PM LeelooMinai: hang*
08:15 PM Cromaglious_: LeelooMinai, find someone with a cnc plasma cutter...
08:35 PM dioz: hah this book says safe working load for a hanger or fastener is manufacturer specs/4
08:36 PM dioz: ie. these quick bolts i have manufacturers specs are 1500 pounds tensile.
08:37 PM dioz: yet this book says i should only try and hold ~375 or so
08:42 PM dioz: doesn't much make sense to me but i'm down with it.
08:57 PM LeelooMinai: Hmm, was playing with my z-axis, and had a though that if the coupler for some reason get loose and power goes down - the whole stage would just slam downwords, wouldn't it...
08:58 PM LeelooMinai: Er, never mind the power - the loose capler would do it...
08:58 PM LeelooMinai: coupler
09:00 PM LeelooMinai: COnsidering that I have the end of mill floating 5cm over the vise jaw, I would not really like it to happen.
09:03 PM LeelooMinai: So, any thoughts on this? Am I right to worry? And if so, are there some ways of preventing this?
09:04 PM * LeelooMinai goes to put a wooden plan under the stage for now...
09:04 PM LeelooMinai: plank*
09:12 PM Cromaglious_: LeelooMinai, you don't have a bottom support on your Z axis screw?
09:15 PM LeelooMinai: I do, but that's at the end of travel, and by that time the endmill will crash with the jaw.
09:22 PM Valen: dioz: manufacturer gives the spec for where it will break, safety margin means you don't use that
09:22 PM Valen: because nothing is ever perfect
09:59 PM roycroft: my first real work on the new lathe went nicely - but it was really simple
09:59 PM roycroft: just some parting, facing, and chamfering
09:59 PM roycroft: nice finish though on everything
10:00 PM roycroft: i did a quick test - i moved the carriage over all the wya to the left, so it was underneath the chuck
10:00 PM roycroft: then i cranked down the carriage lock until i could not move the carriage
10:00 PM roycroft: backed the lock off just enough to be able to move it without undue effort
10:00 PM roycroft: and then cranked it all the way to the right
10:00 PM roycroft: it did not bind anywhere when i did that
10:01 PM roycroft: to me this indicates there's at least not excessive wear on the ways
10:01 PM roycroft: i know it was a purely sensitive test, not quantitative
10:01 PM roycroft: but i think it is a good sign
10:01 PM roycroft: am i wrong about that, and was the exercise completely meaningless?
10:43 PM CaptHindsight: if the middle of the screws are worn they will get difficult to crank near the ends
10:43 PM Cromaglious_: roycroft, I can't do that on my Sheldon... I think it's a good test
10:43 PM CaptHindsight: roycroft: ^^
10:44 PM CaptHindsight: most wear is generally around the center of travel
