12:25 AM jymmmm: Got Safe??? https://www.youtube.com/watch?v=2guvwQvElA8
12:31 AM XXCoder: hes having more problems starting than cutting.
12:37 AM jymmmm: XXCoder: rememebr those HF hydraulic crimpers I was talking about earlier??? https://www.youtube.com/watch?v=ICudP7-FxVw
12:38 AM XXCoder: looking
12:39 AM XXCoder: not surpised on chip but yeah
12:40 AM jymmmm: https://www.aliexpress.com/item/32915939804.html
12:41 AM XXCoder: with that price you have to right right one for it to be profitable]
12:44 AM jymmmm: If I want to get in something I'd just use an angle grinder, but it's nice to know that the crimper has that kind of force to it, so I might be able to make a hole punch die to puch holes in flattened copper pipe bus bars
12:45 AM XXCoder: yeah seems strong enough?
12:45 AM jymmmm: yeah, wasn't expecting that for some reason.
12:53 AM XXCoder: cool
12:56 AM Deejay: moin
12:57 AM jymmmm: morning Deejay
12:58 AM Deejay: hey jymmmm
01:01 AM jymmmm: Ok, this is bad... I mean even worse than HF bad... https://www.youtube.com/watch?v=i7g-TvczpSw
01:04 AM XXCoder: lol thats stupid
01:04 AM XXCoder: "i bought one last year and returned it. my friend had a different model and we tried his key on mine and it opened the safe."
01:04 AM jymmmm: that's pathetic... you can get in faster with a wire, than actually dialing the combo
01:05 AM XXCoder: key pokemon The locks usually have a letter or number on them to identify the key needed to open it. Just write the safe company a letter that you lost your key with the identifying number/letter and they will send you the key. Collect all of them and have all they keys for that model and probably most other safes they sell too."
01:05 AM Deejay: harhar
01:05 AM jymmmm: coat hanger is cheaper and faster
01:05 AM XXCoder: yeah
01:05 AM jymmmm: a sponge... WHAT THE FUCK
01:06 AM jymmmm: seriosuly
01:06 AM Deejay: high security sponge!
01:06 AM jymmmm: yeah, lmao
01:08 AM XXCoder: yeah

01:21 AM jymmmm: haha https://www.youtube.com/watch?v=Chu4mvEUc5I
01:22 AM XXCoder: youre hooked on channel eh
01:24 AM XXCoder: there should be law where "security" means one expert on opening it cant open it for a minute
01:24 AM XXCoder: and "safe" meaning a full hour

04:35 AM JT-Cave: morning
04:52 AM jymmmm: Morning
04:52 AM XXCoder: morning
05:11 AM jymmmm: Tom_L: we're waaaaaiting ;)
07:01 AM JT-Cave: jymmmm, Easy Youtube Video Downloader Express works
08:26 AM Tom_L: jymmmm, you were up so early i didn't wanna disturb ya
08:28 AM JT-Cave: LOL
08:30 AM Tom_L: found the rigid tapping file i used on the sherline. may give it a go today
08:30 AM JT-Cave: cool
08:30 AM JT-Cave: I'm wondering why the 40 pin cable I picked out the the flat cable box prevented the Rpi from booting up
08:33 AM JT-Cave: looking closely it seems to have 60-80 wires which is odd
08:34 AM * JT-Cave tosses that one in the rubbish bin
08:36 AM Tom_L: extra grounding?
08:37 AM pcw_home: That's a Newer IDE cable (that has 80 wires and weird connectors)
08:38 AM pcw_home: I think the extra wires are grounds and terminated to funny (old 40 pin IDE compatible) pins
08:40 AM JT-Cave: thanks, I wonder what that one came out of???
08:40 AM Tom_L: newer ide drive
08:40 AM Tom_L: i've got a couple
08:41 AM JT-Cave: maybe I better not toss it out lol
08:41 AM Tom_L: i kept mine
08:43 AM * JT-Cave takes a red permanent marker and labels it
09:50 AM gregcnc: 3D printer guys who have never machine anything create some really interesting parts they would like to have machined
09:58 AM Tom_L: i bet they do
10:04 AM Tom_L: JT-Cave, https://www.youtube.com/watch?v=EV7crK24eCE
10:06 AM Tom_L: i retapped the holes because i forgot to grab a screw
10:08 AM Tom_L: i haven't been able to figure out the source of that noise, it only does it during tapping so it may be one to get used to
10:09 AM Tom_L: could be the axis interacting with the spindle speed? i dunno
10:10 AM jymmmm: Tom_L: haha, I'm already disturbed, so no worries :D
10:12 AM Tom_L: i wasn't gonna be the one to mention that
10:13 AM gregcnc: you should be able to check the axis and spindle follwing error to determine that?
10:18 AM Tom_L: i've never tried that or know how really
10:20 AM Tom_L: it's resonated off that pulley cover i know
10:21 AM gregcnc: right that was my guess
10:22 AM gregcnc: maybe not following error, but one of the things you can check, axis acceleration may be more useful
10:23 AM Tom_L: the pulley cover may get reworked. i'm not gonna listen to that all the time :D
10:24 AM gregcnc: http://linuxcnc.org/docs/html/hal/tutorial.html#sec:tutorial-halscope
10:35 AM jymmmm: Tom_L: Right to left: hammer crimp, bolt cutter style crimper, hydraulic crimper, soldered, https://youtu.be/PqOa2d8v8Tw?t=1153
10:35 AM _unreal_: hell
10:35 AM _unreal_: hello
10:35 AM _unreal_: ok looking for second opnions
10:35 AM _unreal_: I'm trying to decide how to build the last part of my CNC machine
10:36 AM _unreal_: the interface between the square tube which is the Z
10:36 AM _unreal_: and the attachment mount TO the spindle
10:36 AM _unreal_: I'm looking at thicknesses and metal types
10:36 AM _unreal_: depending on what I'm doing depnds on if I can use my home cnc machine to mill the parts out of the aluminum that I have on hand or if I need to think about using steel?"
10:37 AM _unreal_: so I'm looking for second opinions
10:37 AM _unreal_: give me a few and I'll take some photos etc.. so I can show what it looks like and what I'm dealing with as far as how I should go about planning and proceeding
10:43 AM _unreal_: any one around?
10:44 AM _unreal_: https://drive.google.com/file/d/1QF7kY8lqX4uSXPcerhL73XJY5tb1N18g/view?usp=sharing
10:44 AM _unreal_: https://drive.google.com/file/d/1QLjAP7Bi3AI5SJE3tad5O4uKt1BIE1vi/view?usp=sharing
10:44 AM _unreal_: https://drive.google.com/file/d/1QLHmHYjZq8jkN6GM00Qsj9yGhNzrk_u3/view?usp=sharing
10:45 AM _unreal_: so the photo that shows the spindle off to the side, and the square tube tilted a bit so you can see the shape design and what is attached.
10:46 AM _unreal_: the linear rails are screwed to it nearly to the end where the motor goes. that square tube is 1/4" thick 2x2"
10:47 AM _unreal_: What I'm looking at doing is making something that kind of looks like a 2 prong fork
10:49 AM _unreal_: so 1/2" thick aluminum that is long enough to go inside the square tube by ? 4" inches so I can bolt/glue it into place, and runs along and stops behind the spindle motor where the spindle mount is. between the opening of the square tube and the top of the spindle mount the aluminum is going to go as wide as the spindle mount.
10:50 AM _unreal_: I'm going to then have aluminum strips bolt that the wings that are sticking out and go down to the motor mount
10:51 AM _unreal_: I dont know what the yeild point of the square tube is so I'm not sure if I should go with aluminum of steel
10:51 AM _unreal_: for this interface to mount the spindle to the z body
11:20 AM JT-Cave: weird noise Tom_L
11:20 AM JT-Cave: you should have run the blank through a surface grinder first... looks a bit rough
11:23 AM Tom_L: you should have seen it before i ran the flycutter across it
11:24 AM Tom_L: just some rough sawn scrap i got from a wood shop
12:03 PM gloops: is this still the same build _unreal_? lol
12:05 PM _unreal_: yes
12:05 PM _unreal_: getting closer
12:06 PM unterhaus: I guess the first clue why arduino nano clones and associated terminal boards are so cheap is no mounting holes
12:15 PM unterhaus: got to go find my magnifying glass to tell which pins are which
12:15 PM _unreal_: so no input?
12:18 PM gloops: well, i was worried about 200mm wide 12mm plate bending
12:25 PM _unreal_: \?
12:33 PM _unreal_: I'm thinking the aluminum will be ok
01:01 PM rs[m]: unreal: yield point shouldn't be a design criterion, if it is yielding, it is bending way too much anyways.
01:13 PM _unreal_: I dont know what the yield point of my square tube is
01:13 PM _unreal_: and it more or less has two stiffeners being the rails
01:13 PM _unreal_: that are bolted tight
01:14 PM _unreal_: the rail mount its self has 4 cars that are separated 10"
01:14 PM _unreal_: and mounted to a steel plate
01:17 PM rs[m]: as i said, you should not get anywhere near yield point
01:18 PM rs[m]: you even want elastic deformations to be as small as feasible
01:19 PM rs[m]: whatever. too much prose. no drawings.
01:55 PM Rab: Rails are also not stiffeners, they are things you want to keep from flexing. And they can certainly flex.
01:56 PM * JT-Shop starts writing the PLC program for the tank exploder
02:02 PM robotustra: evening
02:03 PM robotustra: how is everything?
02:04 PM _unreal_: tank exploder?
02:05 PM robotustra: who?
02:06 PM robotustra: _unreal_, how is your progress on smal machine?
02:06 PM robotustra: small*
02:06 PM _unreal_: small machine being the working home one or the new one I"m building? or my daughtesr micro one
02:06 PM robotustra: micro one
02:07 PM robotustra: are you building one more?
02:08 PM robotustra: last time you have showed the micro one
02:08 PM _unreal_: https://drive.google.com/file/d/1C-fuAbumCqSQ0Zs6zVfMSxH7qZYv99aW/view?usp=sharing
02:09 PM robotustra: does not load
02:10 PM robotustra: oh I see
02:10 PM robotustra: what is the screws there?
02:11 PM robotustra: M10?
02:11 PM robotustra: or M8
02:12 PM robotustra: cool
02:12 PM robotustra: little machine
02:13 PM robotustra: I also did some progress on my lathe, finally fitted the spindle to the place
02:13 PM robotustra: week of manual polishing of bushings for bearings
02:16 PM veegee: San Junipero is my favourite episode of Black MIrror
02:16 PM veegee: I love the ending
02:17 PM veegee: I wish it were a real thing
02:17 PM _unreal_: thats not a current photo or video
02:25 PM _unreal: god that is so screwy
02:25 PM _unreal: https://www.buildyourcnc.com/images/mach3USBCardWiringdiagram-800.jpg
02:25 PM _unreal: I am NOT going to use that
02:41 PM robotustra: electronics wiring is coming soon for my device too
02:44 PM unterhaus: sparkfun lied to me about drivers for my arduinos USB, but at least they had them available for download
02:44 PM unterhaus: said they were preinstalled on windows. nope
02:46 PM robotustra: arduino drivers usually installed on windows when you install arduino IDE
02:52 PM unterhaus: they use ftdi. Clones use ch340
03:08 PM _unreal: what ignorant M'F'ERS https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board
03:08 PM _unreal: so there page has a lot of errors on it
03:08 PM _unreal: the I/O pins work just fine and the numbers they list are wrong as well
03:08 PM _unreal: corrisponding to the I/O's
03:08 PM _unreal: I now have all of the i/o's working and mapped out. no thanks to the BS on the page
03:12 PM t4nk_freenode: yeahman ... corrisbonding dokimandation is always full of BS!
03:12 PM t4nk_freenode: why bother reading or writing at all I say
03:13 PM _unreal: there page litteraly says you cant use certain connections for anything but way they say. I tested it anyways and surer then shit works just fine
03:13 PM t4nk_freenode: lol
03:13 PM _unreal: Inow have the + and - limits for xyz working and touch probe and estop all working on the 5v logic inputs
03:14 PM t4nk_freenode: until it explodes :b
03:14 PM _unreal: Istill have 4 high power inputs Ican use
03:14 PM _unreal: whichare more or less useless tome unless I run isolated wires to use them
03:14 PM _unreal: all mywiring is setup for 5v logic limit switches
03:16 PM _unreal: now i'm trying to find the pin numbering for the xyz so Ic an setup the steppers in software on mach3
03:16 PM _unreal: trying
03:19 PM _unreal: omg I dont know what the pinout numbers are
03:19 PM _unreal: for the steppers
03:21 PM t4nk_freenode: do the most logical thing then:
03:21 PM t4nk_freenode: try something random and see if it works
03:21 PM t4nk_freenode: you can always still ask here if it doesn't work
03:32 PM _unreal: I wonder if it is just "" set up ""
03:32 PM _unreal: and there are no pins to setpu
03:38 PM t4nk_freenode: me too!
03:43 PM t4nk_freenode: izzund their annie dokumandation on it?
04:05 PM * Loetmichel just got his Crowpi2 today
04:05 PM Loetmichel: nice little toy.
04:05 PM Loetmichel: bit weak on the computing power though... Sauerbraten runs at 2 fps at fullHD, but that was to be expected
04:05 PM Loetmichel: but for browsing and tinkering with electronics its neat!
04:09 PM unterhaus: how much was it?
04:17 PM __unreal: ok now xyz +/- and estop/probe are working
04:18 PM roycroft: i just cleared out a bunch of space in my electronics lab/fermenting room
04:18 PM roycroft: it looks like my 3d printer will actually move into its ne ew home today out there and get back to work
04:19 PM roycroft: i've not printed anything with it since i started my workbench build in july
04:19 PM roycroft: it's nice getting other projects done finally
04:19 PM Loetmichel: unterhaus: ~230 eur
04:19 PM Loetmichel: plus 43 eur customs
04:21 PM roycroft: it looks like a fun toy, loetmichel
04:22 PM Loetmichel: roycroft: its nice for tinkering with electronics and surfing or youtube or writing documentation
04:22 PM Loetmichel: not so much for anything else
04:23 PM Loetmichel: raspi4-powered, so not THAT much power
04:30 PM unterhaus: I'm tinkering with an arduino today, a laptop format would be nice
04:32 PM __unreal: just finished dbl checking the wiring. cleaning up and prepping to put the box back to gether a bit for a power test
04:32 PM __unreal: see if I can get some motor motion
04:33 PM Tom_L: for more than a sec or so?
04:35 PM __unreal: ?
04:40 PM JT-Shop: 2 1/2 hours to program the tank exploder PLC!
04:46 PM Tom_L: a test tank?
04:52 PM JT-Shop: destructive testing on Briggs tanks
04:54 PM __unreal: JT-Cave, what kind of PLC?
04:54 PM JT-Shop: Click
04:54 PM __unreal: ? click what
04:55 PM __unreal: Idont see anything to click
04:56 PM JT-Shop: try google
04:57 PM t4nk_freenode: so man, __unreal .. what's taking so long? why don't you just fire up that thing of yours and go go go
04:57 PM t4nk_freenode: mill like the whirlwind
05:13 PM t4nk_freenode: this is earth calling Major Berin
05:13 PM t4nk_freenode: HELLO?
05:13 PM t4nk_freenode: you're quite tinohgt
05:14 PM __unreal: I'm fighting software
05:14 PM __unreal: keeps giving me a watchdog error?
05:14 PM __unreal: have yet to find anything that would lead me to WHY
05:14 PM t4nk_freenode: are the motors hot? :)
05:15 PM robotustra: when I do debugging I usually disable watchdog
05:15 PM robotustra: and turn it on in the very end
05:17 PM t4nk_freenode: I don't think __unreal is debugging ;)
05:17 PM robotustra: :)
05:18 PM __unreal: robotustra, are you talking mach3 or lcnc?
05:18 PM __unreal: I'm trying to setup mach3 right now
05:21 PM robotustra: I ok, then I don't know
05:22 PM robotustra: ok*
05:30 PM Tom_L: JT-Shop, do they water fill them to burst test or air?
05:31 PM JT-Cave: AIR
05:31 PM Tom_L: huh
05:31 PM JT-Cave: damn caps lock key
05:32 PM JT-Cave: crap forgot my stripper
05:34 PM __unreal: ok this has to be a feed back error
05:34 PM __unreal: because I just turned off the motor driver power and now I get no errors
05:35 PM JT-Cave: what's on second
05:35 PM __unreal: who
05:35 PM __unreal: who is on first
05:36 PM JT-Cave: yea
05:36 PM __unreal: thats it its the limit switches giving feed back.
05:36 PM t4nk_freenode: perhaps you can just double or triple the power supply, __unreal, that usually solves feedback errata
05:36 PM __unreal: my inputs are totally modular
05:36 PM __unreal: just unpluged them and the error is totally gone
05:38 PM t4nk_freenode: OR
05:38 PM t4nk_freenode: just be smart about it,
05:38 PM t4nk_freenode: and just remember never to switch on the motors!
05:40 PM Tom_L: meh, he's got this
05:41 PM Tom_L: JT-Cave, i thought briggs had pretty well shut down
05:41 PM JT-Cave: no, they are actually picking up again
05:41 PM Tom_L: that's good news
05:42 PM JT-Cave: they shut down the Murray plant a while back and moved all that equipment to Poplar Bluff
05:44 PM JT-Cave: I don't do any work for them directly any more just other plants that supply them with components
05:45 PM Tom_L: so they don't do it all in house
05:45 PM JT-Cave: no, all the plastic parts are done by injection molding places
05:46 PM JT-Cave: they do all the aluminum casting in house
05:46 PM Tom_L: i went thru a plant here a long time ago that among other things wound cables for mower controls. i don't remember what brand
05:46 PM Tom_L: their plastics side did alot of cosmetic cases and medical syringes etc
05:46 PM JT-Cave: the tank exploder is an interesting little project
05:47 PM JT-Cave: raise pressure to 20 psig wait 60 seconds then raise pressure 2 psig per second to either 100 psig or explosion
05:48 PM Tom_L: what's the pass/fail pressure?
05:48 PM JT-Cave: 100 psig
05:49 PM Tom_L: how big is the tank?
05:49 PM Tom_L: test tank
05:49 PM JT-Cave: lawn mower tank dunno a liter maybe
05:49 PM JT-Cave: the test rig is about 2' cube
05:49 PM Tom_L: they don't submerge them in a tank of water?
05:49 PM JT-Cave: no
05:50 PM Tom_L: huh
05:50 PM enleth: JT-Cave: is there a specific reason it's using air instead of a fluid?
05:50 PM JT-Cave: checking weld integrity not for leaks
05:50 PM Tom_L: ok
05:50 PM Tom_L: that makes sense i guess
05:50 PM JT-Cave: yes, the engineer at Briggs in Milwaukee uses air
05:51 PM enleth: well, yeah, but pressure is pressure, welds crack all the same - while using a non-compressible medium for testing is just safer
05:51 PM Tom_L: years ago i worked at a coleman plant and the tank line was right next to my work area
05:51 PM Tom_L: i think they did both
05:51 PM JT-Cave: enleth, well maybe but much messier lol
05:52 PM JT-Cave: if your testing dive tanks yea air is not good...
05:52 PM enleth: JT-Cave: ok, my impression was that most places that test pressure vessels prefer a little mess to clean up over tank shrapnel
05:53 PM JT-Cave: the tank shrapnel is contained in the test rig and actually they just split at the weld so no shrapnel at all
05:54 PM Tom_L: so if you've ever owned a coleman lantern i likely made alot of the fittings on it
05:54 PM JT-Cave: like I said before the engineer at Briggs designed the test we just carry it out
05:54 PM Tom_L: white gas and propane
05:55 PM JT-Cave: I've used a white gas stove and lantern for years
05:55 PM jdh__: what is teh tank material
05:55 PM JT-Cave: some plastic that passed the commiformia emissions test
05:55 PM Tom_L: i was always curious where all the filler caps went... we put out 5600 a shift for all the years i was there
05:55 PM __unreal: omg what in the fuck lol. the machine sounds TOTALLY DIFFERENT withthis other motion controller
05:55 PM __unreal: I mean TOTALLY DIFFERENT
05:55 PM __unreal: it sounds very digital
05:55 PM t4nk_freenode: totally?
05:55 PM JT-Cave: time for me to retire for the night
05:56 PM Tom_L: 6 12' bars about every 20 min
05:56 PM Tom_L: 1" brass
06:08 PM __unreal: ok so I have good motion
06:09 PM __unreal: some weird shit with the sound from the motors but what ever
06:13 PM Tom_L: seems to be a trend today
06:13 PM Tom_L: mine makes a funny noise doing synchronous moves
06:14 PM robotustra: on your mill?
06:14 PM t4nk_freenode: so, got a vid of that sound? one that loads and such
06:14 PM Tom_L: yeah part of it is resonance from the belt cover i put on it
06:14 PM Tom_L: t4nk_freenode, i posted one here earlier
06:15 PM t4nk_freenode: sorry, I meant that for __unreal
06:15 PM robotustra: I fitted spindle today, a week of lapping
06:15 PM Tom_L: mmm
06:16 PM robotustra: I ordered too oversized bushings
06:16 PM robotustra: about 80 microns to remove on average
06:18 PM robotustra: but mcmaster did a nice job actually
06:19 PM robotustra: the sizes of bushinds within 2 microns
06:20 PM robotustra: https://i.imgur.com/hdRvLIF.jpg
06:21 PM robotustra: pulleys, motor mount and mechanics pretty done
06:21 PM Tom_L: getting closer
06:22 PM Tom_L: what sort of cover are you gonna have for the front bearing?
06:23 PM robotustra: don't know yet, thought about rigid cover, but I have small space in there
06:23 PM robotustra: so possibly some sort of cover which Rob Renzetty propose
06:25 PM unterhaus: robotustra what is that machine going to be?
06:26 PM robotustra: https://www.youtube.com/watch?v=qjh63pll0VM
06:26 PM robotustra: it's a cnc lathe
06:27 PM robotustra: 6" 4 jaw chuck
06:27 PM robotustra: or 5" 6 jaw chuck
06:27 PM robotustra: spindle through hole 36 mm
06:27 PM robotustra: 1.2 kW servo motor to drive spindle
06:28 PM robotustra: Z move about 300 mm
06:28 PM robotustra: X move 90 mm
06:29 PM robotustra: Y - if I'll make it 150-200 mm
06:32 PM robotustra: possible I'll make a tailstock or lunette
06:33 PM __unreal: ya that was for me
06:33 PM __unreal: what was for me?
06:34 PM __unreal: oh sound no
06:34 PM robotustra: yes it' was for you :)
06:35 PM robotustra: the video was for Tom_L
06:35 PM robotustra: and all the rest is for you
06:35 PM robotustra: unterhaus
06:35 PM Tom_L: unless you're in a sharing mood
06:36 PM robotustra: yes, mode is sharing
06:36 PM Tom_L: i was talking about the bearing not the way cover
06:37 PM __unreal: doing some more motion tests
06:37 PM __unreal: sounds much better in 1/8 stepping
06:39 PM robotustra: Tom_L, ah, you are talking about spindle bearing cover?
06:39 PM Tom_L: yes
06:39 PM unterhaus: I have thought about making a cnc lathe. Really compact would be good
06:39 PM robotustra: Tom_L, they are done too https://i.imgur.com/PN2W3a2.jpg
06:39 PM __unreal: well that was interesting
06:40 PM __unreal: if I pan around
06:40 PM Tom_L: ok
06:40 PM robotustra: mine will be 90 cm in length, by 55 cm and 40 cm tall
06:41 PM robotustra: unterhaus,
06:41 PM robotustra: unterhaus, some time ago: https://i.imgur.com/JfaIeJU.jpg
06:42 PM unterhaus: nice, thanks for that pic
06:43 PM robotustra: now you should have an idea
06:43 PM unterhaus: I have some nice ballscrews off of a robot that would work well for that
06:43 PM robotustra: this ones are 1605
06:43 PM robotustra: 5 mm step
06:43 PM robotustra: per rotation
06:44 PM robotustra: 16 mm in diameter
06:44 PM unterhaus: The parts I want to make are 25mm by 25mm
06:45 PM robotustra: unterhaus, people usually underestimate the size of parts they want to make ;-)
06:46 PM Tom_L: robotustra, what belt series did you use on the axis?
06:46 PM unterhaus: I know, but a lot of people just can't stop expanding the envelope of their machine
06:47 PM robotustra: Tom_L, HDT-5M
06:47 PM robotustra: for spindle HDT-8M
06:47 PM Tom_L: i went with 5mm but GT2 series
06:47 PM robotustra: I don't expect big precision
06:47 PM Tom_L: iirc the HDT is a predecessor to the GT2
06:48 PM robotustra: 0.02 will be good for me
06:48 PM Tom_L: there's GT3 too but it's hard to find
06:48 PM Tom_L: yeah
06:48 PM Tom_L: i just wanted something stronger than the 3mm one i had
06:49 PM robotustra: unterhaus, this is an housing and chips collector: https://i.imgur.com/8SSKqpe.jpg
06:49 PM XXCoder: wouldnt wood rot under coolant?
06:50 PM unterhaus: are you going to have some kind of stock feeder?
06:50 PM Tom_L: i kinda wondered that myself
06:50 PM robotustra: it's covered with yacht lack and will be covered with aluminium sheet
06:50 PM XXCoder: not sure what yacht lack but cool
06:51 PM robotustra: yacht lack is a varnish to cover yachts
06:51 PM unterhaus: maybe yacht lacquer ?
06:51 PM robotustra: varnish
06:51 PM XXCoder: cool :) so its waterproofing
06:51 PM robotustra: or lacuer, yes
06:52 PM robotustra: water, grease, salt proof
06:52 PM robotustra: salt water proof
06:52 PM robotustra: :)
06:52 PM robotustra: I don't think I'll use too much coolant on this machine
06:53 PM robotustra: may be very local manual sprinkle
06:53 PM unterhaus: I would want a small machine, but lots of coolant
06:53 PM robotustra: to make what?
06:54 PM unterhaus: round things :)
06:54 PM unterhaus: out of stainless
06:54 PM robotustra: clocks?
06:54 PM Tom_L: robotustra, bit of a difference: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/new_pulley_mounted1.jpg
06:54 PM robotustra: watches?
06:54 PM unterhaus: bicycle tool related
06:54 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Motor_Mounted2.jpg
06:55 PM robotustra: Tom_L, did it change the noise?
06:55 PM Tom_L: the first one was with the old sherline spindle motor
06:55 PM Tom_L: some
06:56 PM robotustra: unterhaus, what bicicle tool have size 25x25mm?
06:56 PM Tom_L: they're both GT2 series though
06:56 PM unterhaus: It's just a part. Also probably make hub end caps, which are about the same size
06:57 PM robotustra: Tom_L, oh, you changed the motor
06:57 PM Tom_L: yep
06:57 PM robotustra: 1.2 kw?
06:57 PM Tom_L: yeah
06:57 PM robotustra: how do you control it?
06:57 PM unterhaus: Tom_L, is that the fanciest drive on a Sherline spindle, or have others done that?
06:58 PM Tom_L: unterhaus, i'm not sure
06:58 PM Tom_L: i just knew i wanted positive drive
06:58 PM Tom_L: i burnt up too many stock belts
06:58 PM unterhaus: I wish a sherline spindle would clear 1"
07:01 PM Tom_L: robotustra, from this: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/spindle_cooler/Cooler2.jpg
07:01 PM Tom_L: to this: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Spindle_motor1.jpg
07:01 PM unterhaus: Tom_L, what are you using for toolholding?
07:01 PM Tom_L: still using sherline stuff
07:02 PM Tom_L: i had too much to abandon it
07:02 PM robotustra: Tom_L, did you already make a long run with this motor?
07:03 PM Tom_L: i just finished it couple days ago
07:03 PM Tom_L: did a rigid tap test and a wood project
07:03 PM Tom_L: nothing major
07:03 PM robotustra: ok, what is the max RPM for this motor?
07:03 PM Tom_L: 5600
07:03 PM Tom_L: realistically 5500 or so
07:03 PM robotustra: so, now you are usning built in encoder?
07:03 PM Tom_L: both
07:04 PM Tom_L: it's got hall feedback to the vfd and i'm using the encoder to control a pid loop for the analog to the vfd
07:04 PM Tom_L: so i can get down to ~100 rpm
07:04 PM Tom_L: haven't tried anything lower
07:05 PM robotustra: ah, it's not a spepper, it's an AC motor?
07:05 PM Tom_L: BLDC
07:05 PM robotustra: Mine is 3000 rpm max only
07:06 PM robotustra: but with big torque
07:06 PM Tom_L: https://www.youtube.com/watch?v=EV7crK24eCE
07:06 PM robotustra: constant torque
07:06 PM Tom_L: there's the tap test
07:06 PM Tom_L: yeah this has plenty of torque
07:07 PM Tom_L: i'm trying to figure out the noise. it only happens during synch moves
07:07 PM Tom_L: the belt cover resonates it
07:07 PM robotustra: nice
07:07 PM __unreal: what a difference...
07:08 PM __unreal: My netbook running :S win10 witha single core atom cpu, and a planetcnc setup runs very smooth very fast
07:08 PM __unreal: I can do stuff on the netbook as well
07:08 PM __unreal: this computer I'm using Ithink I need to re-install windows regardless a clean install I forget what I have done with it. I thought I did a clean install but I dont remember
07:08 PM __unreal: running mach3
07:09 PM __unreal: GOD I can hardly do anything with out causing skipping/pausing step loss with this mach3 controller
07:09 PM robotustra: are you sure it's not a win10 issue?
07:09 PM __unreal: even turning my view of the 3D thing being "" milled "" TESTED causes skipping
07:10 PM t4nk_freenode: Wine drinkers from all countries: there's a new cheese board coming out real real soon, __unreal?
07:10 PM t4nk_freenode: :b
07:10 PM __unreal: I'll be glad to get back to the mesa/lcnc setup
07:10 PM __unreal: but I'll have to make do with this POS
07:11 PM __unreal: Ijust cant afford the DOWN TIME of trying to solve all of the issues
07:11 PM __unreal: and not having a wide screen
07:11 PM __unreal: granted this computer has a wide screen its an all in one
07:11 PM __unreal: as well
07:11 PM __unreal: I dont think it would run lcnc very well
07:11 PM __unreal: HP1155
07:12 PM t4nk_freenode: so
07:12 PM t4nk_freenode: any vids?
07:12 PM t4nk_freenode: for us
07:12 PM t4nk_freenode: ??
07:16 PM __unreal: I'm not taking any videos
07:16 PM __unreal: I'm doing hardware testing
07:16 PM t4nk_freenode: snap a video man, dammit, we need to hear the sound
07:16 PM t4nk_freenode: don't seduce us with all that talk, and then.. :|
07:20 PM Tom_L: pics or it never happened!
07:20 PM Tom_L: period.
07:20 PM __unreal: I already got rid of the sound
07:20 PM Tom_L: i didn't but i'm not all that worried about mine
07:20 PM __unreal: oddly enough I changed the timing from 5uS to 1uS on the motor timing
07:21 PM Tom_L: i might look into it one day
07:21 PM __unreal: but the motor controllers call for 5uS??
07:21 PM __unreal: but they do weird shit when set to what they ask for
07:21 PM __unreal: I dont get it
07:21 PM Tom_L: wtf do they know?
07:21 PM Tom_L: have you actually measured it?
07:21 PM __unreal: Tom_L, I'm in full agreement at this point
07:21 PM Tom_L: or is it just a setting that says that
07:21 PM __unreal: I need much better motor controllers
07:21 PM __unreal: WHEN I can afford it
07:22 PM Tom_L: well when you can, gecko is it
07:22 PM __unreal: end of this month fingers crossed I'm going to get my BS 3 in one motor controller
07:22 PM Tom_L: 203v is nearly bullet proof
07:22 PM __unreal: the motor controller that I blew last I had HAD the machine running 4000mm/min
07:22 PM Tom_L: short of unplugging the motor under power
07:23 PM __unreal: it was nice running a 31" axis on 1/2-13threaded rod 12 seconds to get from one end to the other
07:23 PM Tom_L: mine might rapid at that rate but i don't push it
07:24 PM __unreal: ya thats rapids only
07:24 PM __unreal: Ithink I had ONE strong motor controller the rest areweak POS
07:24 PM __unreal: but the second you go over a certain speed they blow
07:24 PM __unreal: god motors are only worm to the touch
07:25 PM __unreal: same withthe motor controllers
07:25 PM __unreal: doing a few tests that run the machine back and forth
07:25 PM Tom_L: my spindle is cold now but i haven't pushed it much yet
07:25 PM Tom_L: the sherline would get too hot to touch
07:25 PM __unreal: sherline spindle?
07:25 PM Tom_L: before i added the copper coil
07:26 PM __unreal: will be interesting to see what my 1.5kw spindle does but it is a water cooled one
07:26 PM jymmmm: Has anyone dealt/bought from SPEMCO ?
07:26 PM Tom_L: never heard of them
07:26 PM __unreal: I plan on getting a 2gal bucket and using this radiator that I have had for YEARS
07:27 PM jymmmm: https://spemco.com/
07:27 PM __unreal: that was for an other project never happend.
07:27 PM __unreal: I'm going to use it as a water cooler
07:27 PM __unreal: prob not needec but then again
07:27 PM Tom_L: __unreal, http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/spindle_cooler/Cooler2.jpg
07:27 PM Tom_L: old
07:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Spindle_motor1.jpg
07:27 PM Tom_L: new
07:28 PM Tom_L: jymmmm, what do they have that you can't live without?
07:28 PM jymmmm: Tom_L: Good price on 150A breaker
07:29 PM __unreal: what ever protocal planetcnc uses. I'm in fucking love with on my small home machine
07:29 PM Tom_L: jymmmm, so what's the holdup?
07:29 PM __unreal: they have a linux version but that requires a different motion controller :(
07:29 PM jymmmm: Tom_L: if they are any good, fly by night, etc
07:30 PM Tom_L: they look like a broker
07:31 PM jymmmm: just found https://www.waytekwire.com/ too
07:31 PM Tom_L: what brand is the braker?
07:31 PM Tom_L: breaker
07:31 PM jymmmm: BUSS MRCB 150 panel mount
07:32 PM jymmmm: Tom_L: Eaton 187150P-03-1
07:32 PM Tom_L: eaton is good.... no?
07:33 PM Tom_L: what for?
07:33 PM Tom_L: your solar stuff?
07:33 PM jymmmm: Tom_L: power station
07:37 PM __unreal: wow it doesnt take much to cause a crital pause
07:38 PM jymmmm: Why in the hell don't any of the distributors carry silicone wire?
07:39 PM Tom_L: not that widely used?
07:39 PM Tom_L: cost?
07:39 PM Tom_L: what do they use in plenums?
07:39 PM Tom_L: teflon?
07:40 PM jymmmm: and I doubt 8ga
07:44 PM jymmmm: $1.16/ft sound reasonable?
07:48 PM __unreal: jymm silicone wire
07:49 PM __unreal: what guage do you need
07:49 PM __unreal: Ihave a source :)
07:49 PM __unreal: jymmmm, ?
07:49 PM __unreal: hello?
07:49 PM __unreal: sigh
07:50 PM t4nk_freenode: HELO!?
07:51 PM jymmmm: __unreal: 8ga
07:53 PM __unreal: oh.. :S maybe
07:53 PM __unreal: jymmmm, try hobbyking.com
07:53 PM __unreal: most people use sillicon wire for RC toys
07:53 PM __unreal: cars, planes, quad copters etc...
07:54 PM __unreal: big quads use very big motors and power
07:54 PM __unreal: it may pan out for ya
08:11 PM jymmmm: __unreal: thanks but they only offer 1m lengths
08:15 PM gregcnc: why silicone?
08:21 PM W1N9Zr0: amazon has silicone wire
08:24 PM Tom_L: jymmmm, how much do you need?
08:24 PM Tom_L: https://www.calmont.com/2017/08/the-most-popular-applications-for-silicone-wire-and-cable/
08:31 PM snakedGT is now known as snaked
08:32 PM Tom_L: gregcnc, investigation told me alot of that noise was resonance from _BOTH_ belt covers. the steel one at the back (Z) was picking up alot of those vibrations.
08:33 PM Tom_L: synchronous motion is still noisier than normal z movement but i don't think it's anything to worry with
08:46 PM _unreal_: oaaaahahahahah
08:46 PM _unreal_: https://www.youtube.com/watch?v=x7HoX8hWkp0
08:55 PM Tom_L: robotustra, as little tapping i would do i'm not too worried about it
09:02 PM jesseg: Tapping, tapping, at your lattice door.
10:11 PM roycroft: i replaced the bowden tube on my printer before i moved it to its new home
10:12 PM roycroft: i'm printing a collet storage tray now that will take a while longer, but so far it looks like it will be the best print i've made with this machine
10:12 PM roycroft: so yeah, that is a nice $13 upgrade
10:15 PM XXCoder: nice
10:17 PM roycroft: yeah, someone suggested doing it and said it would probably be a really big improvement, and i think it is
10:20 PM unterhaus: I need to figure out what timing belt to get for my lathe but I don't have the old belt
10:21 PM XXCoder: no way to find out using model number of lathe?
10:29 PM unterhaus: not that google reveals
10:29 PM unterhaus: asked on the mailing list
10:30 PM unterhaus: the parts manual is nearly useless, sheldon renumbered everything
10:30 PM XXCoder: :(
10:30 PM unterhaus: I'm sure I could get fairly close, and there is a take-up pulley if I'm off a couple of teeth
10:30 PM XXCoder: maybe part # renumbered to
10:30 PM XXCoder: google might find it
10:31 PM unterhaus: I was going to try that and forgot
10:32 PM unterhaus: well, their naming system conflicts with American Airlines flights
10:32 PM unterhaus: AA 1569
10:32 PM unterhaus: goes to paris
10:33 PM unterhaus: not really, pheonix to boston
10:33 PM XXCoder: http://pics.woodstockint.com/manuals/sb1051f_m.pdf
10:35 PM unterhaus: my lathe is a sheldon R13, no relation to south bend
10:36 PM unterhaus: one of the guys that used to work at sheldon has all the drawings and can cross part numbers
10:37 PM unterhaus: haven't seen him post in a long time though
10:42 PM _unreal_: fun fun just killed a recluse
10:43 PM XXCoder: no luck on finding manual
10:43 PM XXCoder: tons of fake "forum"
10:43 PM XXCoder: hint is its many domains but "posts" are all same lol
10:44 PM unterhaus: I have the manual
10:44 PM unterhaus: both manuals
10:44 PM XXCoder: nice
10:45 PM unterhaus: it's just that the only part number is an internal one
10:45 PM XXCoder: its amazing how hard it is to find those sometimes
10:45 PM XXCoder: so aa 1569 is internal number eh
10:45 PM unterhaus: not sure why you're having trouble, I found it in a few minutes. But I use my copy now
10:46 PM XXCoder: cant call company?
10:46 PM unterhaus: company long gone
10:47 PM unterhaus: there was a company they sold their drawings to, but they aren't around either
10:48 PM unterhaus: I don't think they were interested in answering questions like this, only making gears
10:49 PM XXCoder: nothing at all out there. even "sheldon R13" broken belt, nothing
10:50 PM XXCoder: hope there was some forym where someone answered whatever was compitable lol
10:50 PM XXCoder: honestly that theyre not interested. more business
10:50 PM XXCoder: sorry my google-fu failed
10:54 PM jymmmm: unterhaus: You could contect the person who bought the lathe and ask him to measure for you... https://www.hobby-machinist.com/threads/sheldon-lathe.60430/
10:55 PM jymmmm: contact*
10:55 PM unterhaus: I can ask Jon Elson, he has the same belt
10:55 PM jymmmm: ah ok
10:56 PM unterhaus: they usually say the part number on them, right?
10:56 PM unterhaus: thought I would ask on the mailing list first, but Jon will probably answer my email
10:57 PM unterhaus: I have half-heartedly looked to see if I took it off
10:58 PM unterhaus: I successfully replaced all the timing belts on my bridgeport without part numbers, so it's not that hard
11:08 PM XXCoder: thats good
11:11 PM unterhaus: I figured if I asked I would find the old one
11:17 PM XXCoder: can always measure and buy and pray I guess
11:24 PM unterhaus: I think there is quite a bit of adjustment, have to look
11:24 PM unterhaus: at least while I was looking for the belt, I found out there were some bad potatoes down there
11:28 PM gloops: https://store.lathes.co.uk/print/ms526e
11:28 PM gloops: a bit pricey for the manual
11:29 PM gloops: https://ozarktoolmanuals.com/machinemanual/sheldon-r13-r15-r17-precision-metal-lathe-operators-manual/
11:31 PM unterhaus: I have the manual
11:31 PM unterhaus: there is a parts manual too, so if you pay someone for both you're really getting ripped off
11:32 PM unterhaus: it's right there in the file section of the sheldon mailing list
11:33 PM unterhaus: the parts manual is very useful for taking the lathe apart, but there are very few useful part numbers
11:34 PM gloops: yeah $15 for the parts manual pdf, but no use if doesnt give info that helps calculate dimensions or modern equivalent right
11:36 PM unterhaus: it's well worth it, if it wasn't available for free
11:37 PM unterhaus: funny thing about the parts manual is that half of it is just photocopies of the drawings
11:37 PM unterhaus: I would pay real money for the drawings
11:38 PM unterhaus: it looks like they were wonderfully done
