02:57 AM rue_mohr: wow, tahts screwed! :)
01:53 PM z64555: Morning folks, here's a comic for today: http://freefall.purrsia.com/ff3100/fc03059.png
03:02 PM -!- #robotics mode set to +o by adams.freenode.net
07:22 PM anonnumberanon: Hi
07:25 PM mrdata-: lo
07:25 PM anonnumberanon: Wat u working on
07:26 PM mrdata-: a circuit stress tester
07:26 PM mrdata-: because if north korea ever pops a nuke over washington, i'd like to know in advance what electronics i can still rely on
07:28 PM mrdata-: so i have simulated a resonant circuit that produces 240 ampere-turns of magnetic field, on a 860 kHz cycle
07:28 PM mrdata-: should i build it?
07:32 PM anonnumberanon: Dont know
07:33 PM anonnumberanon: Thats for you to decide
07:34 PM mrdata-: ok
07:36 PM mrdata-: the simplest victim circuit is a loop of wire with an LED across it
07:36 PM mrdata-: and idk how close this needs to get to the coil, but i will test that
07:37 PM mrdata-: so, if it breaks the LED then i will expect it to break other things, too
07:37 PM mrdata-: but it should at least light up
07:37 PM anonnumberanon: Your gonna try to break it?
07:37 PM mrdata-: it depends on magnetic coupling
07:38 PM anonnumberanon: How will you power it?
07:38 PM mrdata-: so, if the victim is encircled by the resonant coil, then the coupling would be strong
07:38 PM mrdata-: in favourable directions
07:38 PM mrdata-: the resonant circuit will be pumped by a pulse generator
07:39 PM mrdata-: i expect it to have a high Q factor, > 600
07:40 PM mrdata-: consequently it will build up 10 kV
07:40 PM mrdata-: ish
07:43 PM rue_mohr: anonnumberanon, have you found a machine to tear apart for steppers and drivers?
07:44 PM anonnumberanon: No
07:44 PM rue_mohr: dang
07:44 PM rue_mohr: did you get a driver for the motor you have?
07:44 PM anonnumberanon: Im swamped
07:44 PM anonnumberanon: Yeah i have adriver
07:45 PM rue_mohr: cool we should set it up on grbl and calibrate distance when ya have a chance
07:45 PM rue_mohr: say when, next week I'm off work
07:49 PM mrdata-: https://imgur.com/a/zXdOc
07:51 PM anonnumberanon: Yeah im off next week too
07:52 PM rue_mohr: heh
07:52 PM anonnumberanon: Ill be practicing my metal fab too.
07:53 PM anonnumberanon: Getting a good assortment of aluminum, steel tubing
07:53 PM mrdata-: nice
07:53 PM anonnumberanon: Drill press, belt sander machine, horizontal bandsaw
07:53 PM mrdata-: any exotic metals?
07:54 PM mrdata-: those horizontal bandsaws are great for cutting pipes
07:54 PM anonnumberanon: Will try to get my oarents to get me tge bandsaw cause its 200 bucks
07:55 PM anonnumberanon: The other 2 machines are 75 each
07:57 PM anonnumberanon: But nah no fancy metals, maybe ill make small part from titanium but thats a little harder to do that steel, which is already hard yo do
07:58 PM anonnumberanon: Not next week tho
07:58 PM anonnumberanon: When my cnc runs
07:58 PM anonnumberanon: Those parts would take a really long time to make to keep the mill from blowing to pieces
07:59 PM anonnumberanon: Coolant will hrlp a great deal
08:00 PM anonnumberanon: Why u need a part mrdata?
08:07 PM Tom_L: rue_mohr, ya do what ya gotta do: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Drillpress.jpg
08:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/BaseBolts1.jpg
08:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/BaseBolts2.jpg
08:09 PM rue_mohr: that there is a tight fit
08:09 PM Tom_L: i could have drilled them before i tacked it but i wanted the column to align with the base as close as possile
08:10 PM rue_mohr: k
08:10 PM rue_mohr: armyofevilrobots,
08:10 PM rue_mohr: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/BaseBolts2.jpg <-- gas problem?
08:10 PM rue_mohr: aka, oops its off?
08:10 PM Tom_L: huh?
08:11 PM Tom_L: oh that seam?
08:11 PM Tom_L: that's a double weld
08:11 PM rue_mohr: the splat beside the tack
08:11 PM Tom_L: no, it probably had too much wire sticking out on that one
08:12 PM Tom_L: when it arc'd
08:12 PM rue_mohr: endcaps for those pipes eh?
08:12 PM Tom_L: i'm not sure i'm gonna do that
08:12 PM rue_mohr: otherwise they will sidesheer springs on ya
08:12 PM Tom_L: maybe later
08:12 PM rue_mohr: /
08:12 PM rue_mohr: \\
08:12 PM rue_mohr: //
08:12 PM Tom_L: i know
08:13 PM Tom_L: i'll see
08:13 PM rue_mohr: k
08:13 PM Tom_L: it's pretty solid
08:13 PM Tom_L: consider the size bits i'll be using
08:13 PM rue_mohr: its the impact movement
08:13 PM rue_mohr: ring
08:13 PM Tom_L: those ain't gonna move it
08:13 PM rue_mohr: a pole in its transfer function
08:13 PM rue_mohr: ______|_____
08:14 PM rue_mohr: ____i_|_i______
08:14 PM armyofevilrobots: hey what what?
08:14 PM rue_mohr: armyofevilrobots, ^ toms cnc
08:15 PM z64555: rue's trying to do ascii art
08:15 PM rue_mohr: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/BaseBolts1.jpg
08:15 PM rue_mohr: I'v not got room yet to start on the new one I want to make
08:15 PM armyofevilrobots: Ah. Gotcha.
08:15 PM armyofevilrobots: Yep was just looking at it.
08:16 PM rue_mohr: Tom_L, shoot armyofevilrobots a rendering
08:16 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Column_Mill_VMC.jpg
08:16 PM armyofevilrobots: Sweeet!
08:17 PM armyofevilrobots: Yeah, I was wondering about that plate being a big flexy at the bottom of the tower, but those ribs will stiffen it right up I think.
08:17 PM Tom_L: 3" triangles 1/4" plate
08:17 PM armyofevilrobots: Any problems with distortion from the welding?
08:17 PM Tom_L: just a tiny bit but i think i can fix it
08:17 PM Tom_L: not as much as i had expected
08:18 PM rue_mohr: your buddy gonna mill it for ya still?
08:18 PM armyofevilrobots: Last time I saw one of these go together, the dude lapped the base on a granite block after.
08:18 PM Tom_L: i haven't called him but i'm sure he will
08:18 PM armyofevilrobots: The tower was on straight, but the base had bowled up a bit.
08:18 PM Tom_L: same here
08:18 PM armyofevilrobots: a bit -> 5-thou or something. Not a lot.
08:18 PM Tom_L: i'm gonna stick it on a brigeport
08:18 PM rue_mohr: I need to learn counter-distortion welding
08:19 PM Tom_L: i tried but there was no avoiding it around the stepper mount end
08:19 PM armyofevilrobots: @rue_mohr I was just welding up a bike frame trying to do that. It _kinda_ worked :D I’ll share once I finish.
08:19 PM rue_mohr: :) oh yea, cool
08:19 PM rue_mohr: just assumed that was all still pending
08:19 PM armyofevilrobots: Speaking of, just built up my Dad’s electric bike yesterday. Those cheap-ass Bafang drives have some grunt!
08:19 PM rue_mohr: ?
08:20 PM armyofevilrobots: Thing feels like a 55cc scooter taking off, which isn’t huge power, except it’s an e-bike.
08:20 PM rue_mohr: :)
08:20 PM armyofevilrobots: This thing: https://lunacycle.com/bafang-bbs02-mid-drive-kit/
08:20 PM Tom_L: i thought about finding a shop that could normalize the metal but i'm afraid what it would cost
08:20 PM anonnumberanon: Nice chips on that drilling
08:20 PM rue_mohr: :/ I'd like to try my trike project again
08:21 PM rue_mohr: huh
08:21 PM Tom_L: rue_mohr, you can get an idea of my steel table there
08:22 PM Tom_L: 1/2" plate
08:22 PM rue_mohr: hah, its so dirty I just assumed its wood
08:23 PM Tom_L: it was all painted nice at one point
08:23 PM rue_mohr: I feel less guilty knowif I'm not the only one who piles my files
08:25 PM armyofevilrobots: Current progress: https://files.armyofevilrobots.com/f/d283a0c846/
08:26 PM Tom_L: what's that for?
08:26 PM Tom_L: are those 20mm?
08:26 PM armyofevilrobots: Changing my old shitty gantry bearings from skate bearings to 40mm HGH linear rails.
08:26 PM armyofevilrobots: It’s a 4.5’ square gantry cnc.
08:26 PM Tom_L: nice n heavy ones
08:26 PM Tom_L: i didn't want a gantry
08:26 PM Tom_L: thought about it a bit
08:27 PM armyofevilrobots: Yeah. I wasn’t gonna go so big, but they had a promo on those big rails so I went up for about a 15% increase in price.
08:27 PM armyofevilrobots: It’s a woodworking machine.
08:27 PM Tom_L: makes a difference
08:28 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Z_Axis_Plate_screws1.jpg
08:28 PM Tom_L: there's the z offset plate
08:28 PM Tom_L: if i ever need more reach i can always replace it
08:30 PM rue_mohr: armyofevilrobots, I'm still interested to get the old cold rolled from ya
08:30 PM armyofevilrobots: Yep.
08:30 PM rue_mohr: I'm eager to try to make box slides
08:30 PM armyofevilrobots: I will probably keep one of them to turn into a cabinet making slide on my table saw. The other two will be up for grabs.
08:30 PM rue_mohr: +- the mill I have to shape them a bit with
08:30 PM rue_mohr: I'm shooting for something about the size of the sherline
08:31 PM Tom_L: go big or go home!
08:31 PM rue_mohr: otherwise similar to toms deisgn
08:31 PM armyofevilrobots: I need to get a granite table… Precision with hand tools is a challenge without it. Using the table-saw’s cast iron table, but it’s only +- a couple thou.
08:31 PM Tom_L: you need more Y than the sherline has
08:31 PM armyofevilrobots: Yeah, and more rigidity. You can push the head back and forth a mm or more without any effort, one-handed.
08:31 PM rue_mohr: oh Y, yea
08:31 PM rue_mohr: yea, the Y on the sherline is just frustrating
08:32 PM Tom_L: i should have about 9 or 10"
08:32 PM armyofevilrobots: Anyhow, off to drawing land again.
08:32 PM Tom_L: what cad do you use?
08:32 PM Tom_L: oh nm, that's SW
08:35 PM armyofevilrobots: Yeah. I’ve been on SW since ’97 or so.
08:35 PM armyofevilrobots: Holy shit… I am old :(
08:36 PM rue_mohr: haha
08:36 PM Tom_L: i had 04
08:36 PM Tom_L: dunno what it is now
08:36 PM Tom_L: but
08:36 PM Tom_L: i've got dos based cad cam if that make ya feel any better
08:37 PM anonnumberanon: What is a granite table?
08:37 PM Tom_L: an inspection surface
08:37 PM anonnumberanon: Oh?
08:37 PM orlock: we have one here
08:37 PM orlock: with a big moving gantry above it
08:37 PM anonnumberanon: Where to get one?
08:38 PM Tom_L: graveyard
08:38 PM Tom_L: :)
08:38 PM orlock: anonnumberanon: kitchen supplies? the tricky bit is getting a flat one...
08:38 PM Tom_itx: https://cnc-specialty-store.com/measuring-inspection/surface-plates/precision-granite-surface-plate-18-x-18-x-3-grade-a-or-b?gclid=EAIaIQobChMItZDPxoWV2AIVh7bACh0b6A2lEAQYASABEgJAo_D_BwE
08:38 PM Tom_L: anonnumberanon ^^
08:39 PM z64555: graveyard, 'cause ain't nobody going to sell em. Machinists will take them to the grave
08:39 PM z64555: I think that's the joke...
08:39 PM Tom_L: heh
08:40 PM rue_mohr: armyofevilrobots, measure the backlash in that last machine I made at 0.17mm
08:40 PM Tom_itx: my bud has one about like this one: https://www.mscdirect.com/browse/tnpla/86433406?cid=ppc-google-New+-+Measuring+%26+Inspecting+-+PLA_s5KFkmctm___164110844328_c_S&mkwid=s5KFkmctm|dc&pcrid=164110844328&rd=k&product_id=86433406&gclid=EAIaIQobChMItZDPxoWV2AIVh7bACh0b6A2lEAQYCCABEgLAn_D_BwE
08:40 PM orlock: ours is part of our CMM
08:40 PM orlock: https://en.wikipedia.org/wiki/Coordinate-measuring_machine
08:40 PM Tom_L: orlock, yeah he's got his old one too
08:40 PM orlock: Mitutoyo
08:40 PM Tom_L: they parted it otu
08:41 PM armyofevilrobots: Oooh. That’s a nice big chunk o granite.
08:41 PM armyofevilrobots: I only need 36” for most stuff.
08:42 PM orlock: They had to raise the cieling for ours
08:42 PM orlock: its in its own climate controlled room
08:42 PM Tom_L: different grades are different flatness
08:42 PM Tom_L: orlock that's how it's supposed to be
08:42 PM Tom_L: all inspection equipment should be
08:42 PM rue_mohr: wait, that was a wikipedia page and I didn't have to close a whole bunch of windows about them needing more money, did they sell out?
08:42 PM orlock: we even have an ex-toyota person whose job is to drive it
08:43 PM rue_mohr: I'd like to know the tolerance on a moulded plastic servo case
08:43 PM rue_mohr: esp if its more or less than .17mm
08:43 PM Tom_L: better
08:44 PM Tom_L: actually that's probably about right
08:44 PM Tom_L: .006
08:44 PM Tom_L: "
08:45 PM anonnumberanon: >$300...
08:46 PM anonnumberanon: Good joke z64
08:46 PM Tom_L: rue_mohr, it's probably gonna be a while before i make it out to my bud's
08:46 PM Tom_L: i'm just too busy right now
08:47 PM rue_mohr: yea, there is a tree dieing in the livingroom that needs ot be tended to over the next 2 weeks
08:47 PM anonnumberanon: Gonna draw a machine tonight..
08:47 PM Tom_L: think hard about it as you go
08:47 PM rue_mohr: complex die?
08:48 PM rue_mohr: anonnumberanon, are you drawing it from wire, or an ingot?
08:48 PM anonnumberanon: Off the shelf parts, you'll see
08:49 PM rue_mohr: yea, I can see my method of getting you experience building motion systems before you try to make a whole cnc isn't gonna work
08:50 PM rue_mohr: tried, failed, now I'll wait and watch
08:50 PM rue_mohr: anonnumberanon, your in for a $800 ride, and I'm curious to see what you end with
08:50 PM rue_mohr: possibly more
08:50 PM rue_mohr: you could sink $4k into this
08:50 PM anonnumberanon: Are you joking my cardboard cnc you got me to make was holding at least 3 thou
08:51 PM rue_mohr: and end up with soemthing crookid that binds, so I'm hoping it goes well
08:51 PM rue_mohr: anonnumberanon, it was a practise run, shall I ... looks at calandar.... build a cardboard xyz by friday to show ya what I was thinking?
08:52 PM rue_mohr: if so, I'd better start some cardboard drying...
08:52 PM orlock: drying? what you doing to it? glue coating?
08:53 PM rue_mohr: on the covered deck, its moist out
08:53 PM anonnumberanon: rue i dont thing i need to build abymore cardboard stuff now
08:53 PM rue_mohr: it was a practise run, you learned from it
08:54 PM rue_mohr: its physical existance currently holds no value
08:54 PM rue_mohr: it cost nothing, it was sacraficial
08:54 PM anonnumberanon: But
08:54 PM rue_mohr: that was its job
08:55 PM anonnumberanon: Maybe we can start talking about how to make straight things out of steel
08:55 PM rue_mohr: its job was to allow you to fail with no fiscal cost
08:55 PM rue_mohr: ooo sentence fail
08:55 PM anonnumberanon: But look are u listening?
08:55 PM rue_mohr: yep
08:56 PM rue_mohr: I dont think my way will work for you
08:56 PM rue_mohr: its part of what I learned
08:56 PM rue_mohr: thre was a chance
08:56 PM anonnumberanon: Oh wait thats right u did not read my LibreCalc file
08:56 PM rue_mohr: you want to go buy a bunch of steel
08:56 PM anonnumberanon: Iif you had read my file..
08:56 PM rue_mohr: my suggestion would be to get a bunch of free scrap and try welding soemting up, its a step up ditto of the caordbaord
08:57 PM anonnumberanon: You would have seen the truth.
08:57 PM anonnumberanon: Read it.
08:57 PM rue_mohr: dont have libreoffice on my normal machines
08:57 PM anonnumberanon: PLEASE
08:57 PM rue_mohr: its not on this computer
08:57 PM rue_mohr: and I cant install it now, it wants to remove X
08:57 PM orlock: if you are sure it's going to work, just send the DXF files off to the local laser cutting place
08:57 PM orlock: and bolt together the results?
08:57 PM z64555: MS programs should be able to load it
08:57 PM rue_mohr: which is detremental to the use of my machine
08:58 PM z64555: might be an online viewer, too
08:58 PM Tom_L: rue_mohr, frustrating trying to get someone to do something isn't it?
08:58 PM rue_mohr: anonnumberanon, you said the exif info would be lost, you have embedded images?
08:58 PM anonnumberanon: I dont think rue has microsoft excel
08:58 PM rue_mohr: Tom_L, yea I'm horrid
08:58 PM * Tom_L thinks about linuxcnc and looks at rue
08:58 PM rue_mohr: I dont, I have gnumeric
08:58 PM anonnumberanon: Lol
08:58 PM rue_mohr: so I can open xls
08:58 PM rue_mohr: Tom_L, cost of hardware to make it usefull is too high
08:59 PM anonnumberanon: Orlock
08:59 PM Tom_L: i could possibly come up with a spare set
08:59 PM anonnumberanon: I want to stop u here
08:59 PM Tom_L: then what?
08:59 PM orlock: anonnumberanon: beyonce had the best music video of all time?
08:59 PM anonnumberanon: Im not trying to pay for a kit heh
08:59 PM rue_mohr: yes, but you know if anything went wrong I'd be pooched
09:00 PM rue_mohr: and you have to admit, grbl does the basics
09:00 PM anonnumberanon: I feel making my frame myself will be part of the fun
09:00 PM Tom_L: rue_mohr, acually grbl lacking a few features isn't too bad
09:00 PM anonnumberanon: In a few minutes rue i may take a screenshot of my acreen to show u
09:00 PM Tom_L: but it's harder to interface to the real world with cad cam
09:00 PM rue_mohr: ok
09:00 PM rue_mohr: anonnumberanon, or export the file to sometin g
09:01 PM rue_mohr: Tom_L, linuxcnc doesn't have any cam in it, does it?
09:01 PM rue_mohr: by now I should know :(
09:01 PM Tom_L: some simple stuff yes
09:01 PM rue_mohr: more than bcnc?
09:01 PM * rue_mohr shudders
09:01 PM anonnumberanon: DUDE WHY why i put in any work exporting a file that is already absolutely free software and all that stuff. Feels like a crime.
09:01 PM Tom_L: i'm not familiar with it
09:02 PM anonnumberanon: Free as in freedom.
09:02 PM rue_mohr: anonnumberanon, "system wants to remove X to install that softawre, which is detremental to the use of my machine"
09:02 PM orlock: What's wrong with CSV again?
09:02 PM anonnumberanon: And i understand that. But uhm... its kind of ghetto if you ask me..
09:03 PM rue_mohr: ask when I'm in the shop, I think it has libreoffice
09:03 PM anonnumberanon: Ok but look.
09:03 PM Tom_L: http://linuxcnc.org/docs/2.7/html/gui/image-to-gcode.html
09:03 PM Tom_L: is one
09:03 PM Tom_L: part of it
09:03 PM anonnumberanon: Once you see it i think you will find that it is a lot closer to what you would have me do than you think.
09:04 PM rue_mohr: :) thats what my first cnc started with
09:04 PM AchiestDragon: cant you export it to pdf , or print it to a pdf file at least thats some format we all are able to view
09:04 PM rue_mohr: pdf would work
09:04 PM anonnumberanon: I dont know what librecalc exports to
09:04 PM anonnumberanon: Ill check
09:04 PM Tom_L: it's got a few other things but i've never used them so i'm not sure where to find the docs for them
09:04 PM anonnumberanon: Probably almost everything
09:04 PM rue_mohr: my program takes tga s
09:05 PM rue_mohr: 8 bit uncompressed greyscale TGA
09:05 PM AchiestDragon: print > > printer type file as in print to pdf
09:05 PM * anonnumberanon goes to shower then gonna boot up the lean mean linux OS
09:05 PM Tom_L: http://linuxcnc.org/docs/2.7/html/examples/gcode.html
09:05 PM anonnumberanon: And get off this horrendous phone irc client lol :)
09:06 PM rue_mohr: I need to finish my cam program
09:06 PM rue_mohr: I can see the data in a dxf currently
09:06 PM Tom_L: or learn mine
09:06 PM rue_mohr: first thing is to set up jobs to drill holes on points
09:06 PM anonnumberanon: One more thing. I am not ordering anything before i finish the frame.
09:06 PM rue_mohr: Tom_L, I want soemthing for linux
09:06 PM rue_mohr: anonnumberanon, frames
09:06 PM anonnumberanon: Except for tools ofc.
09:07 PM anonnumberanon: ??
09:07 PM rue_mohr: assume the first one is a writeoff
09:07 PM Tom_L: anonnumberanon i thought that too but needed dimensions from the actual hardware
09:07 PM anonnumberanon: Well i wont build several machines ill just modify one. Thats what cutting and welding is for.
09:08 PM rue_mohr: I close my eyes, and there is the image of a flat green grass field at night, with the light fading to dark in the background, and a black hole in th ground, with a cat, bouncing in and out of it.... what does this mean?
09:08 PM rue_mohr: anonnumberanon, no, but eth first frame will be a writeoff
09:09 PM rue_mohr: if its made to $1000 in steel or $2
09:09 PM Tom_L: mine is all made from scrap
09:09 PM armyofevilrobots: @rue_mohr I don’t know… but I’ll have what you’re having.
09:09 PM rue_mohr: I'v started 5 machines, and finished 3
09:09 PM anonnumberanon: $1000 of steel?
09:10 PM rue_mohr: the other 2 were scrap, different reasons, but not usable cnc machines
09:10 PM rue_mohr: armyofevilrobots, :)
09:10 PM anonnumberanon: Im gonna get new steel tubing from home depot
09:10 PM rue_mohr: $1000 ok
09:10 PM anonnumberanon: It will be cheap. Steel is cheap
09:10 PM rue_mohr: hah
09:11 PM rue_mohr: lesson 1, steel, esp from home depot, isn't cheap
09:11 PM Tom_L: not from them
09:11 PM anonnumberanon: Gtfo
09:11 PM rue_mohr: hehe, hey, I'm just sayin
09:11 PM anonnumberanon: Ok now ill check prices. Shower and brb.
09:11 PM Tom_L: you got a scrap yard near you?
09:12 PM rue_mohr: not is shrink wrapped lumber in the city, wholy f*** that was insane
09:12 PM rue_mohr: Tom_L, he wont wanna go that dir
09:12 PM Tom_L: it's kinda fun hunting for what you need
09:12 PM rue_mohr: I would totally suggest if for him for his first pass, but, he wont
09:12 PM Tom_L: i was rather excited to find that NEW piece the other day
09:13 PM rue_mohr: I love looking thru the massive pile in <other town>
09:13 PM Tom_L: that base plate looks pretty clean to me
09:13 PM rue_mohr: thats awesome stuff
09:13 PM Tom_L: compared to that rust i had before
09:14 PM orlock: rue_mohr: you forgot to backfill zombiekitty's new home?
09:14 PM AchiestDragon: 3 router worked , , another 3 failed atttempts at a smaller one , and the 3d printer is a first atempt at a printer , cant say that was a failure although its currently broken ,, and countless cad drwaings that never made it to construction
09:15 PM rue_mohr: my 3d printer worked first time, but I didn't design it, and I had a lot of practise building things like that
09:15 PM rue_mohr: 2nd printer was an attack on all the design aspects I hated about the first one
09:15 PM rue_mohr: it works
09:15 PM rue_mohr: 3rd will prolly be a paste extruding printer
09:16 PM AchiestDragon: bloked nozzle and bust psu but machanicaly its fine
09:16 PM rue_mohr: armyofevilrobots, I'm still trying to work out how people set up marlin for paste extrusion,
09:16 PM rue_mohr: hah,
09:16 PM rue_mohr: AchiestDragon, straighten a small spring, heat nozzel up and jam like crazy
09:17 PM rue_mohr: the spring wire is good strength and can usually be found in good small sizes
09:17 PM AchiestDragon: anyway got a new tevo delta on the way in the post , may get arround to fixing the other if i find i need it
09:17 PM rue_mohr: I print soemthing every week
09:18 PM rue_mohr: https://www.thingiverse.com/make:418112
09:18 PM rue_mohr: guess what I'm up to?
09:18 PM rue_mohr: }:]
09:18 PM rue_mohr: NO its not a solder printer...
09:20 PM AchiestDragon: you going to put it on a robot with a soldering iron and have it soldering for you ?
09:21 PM orlock: rue_mohr: You dont like clear filament?!?!?!
09:21 PM rue_mohr: I just want a machine that can give me more solder when I need it
09:21 PM rue_mohr: orlock, brittle as all hell
09:21 PM rue_mohr: after 2 hours it snaps
09:21 PM orlock: rue_mohr: You gotta subtract the space for an LED and start press-fitting them in there
09:21 PM rue_mohr: and I have to ditch about 20cm of it
09:22 PM rue_mohr: (2 hours of machine not printing)
09:22 PM rue_mohr: all the translucent filament seems to ahve that property, brittle spools
09:22 PM orlock: i had no problems with mine - the clear PLA is actually "natural" i think
09:22 PM rue_mohr: yea, real clear filament or translucent colours, *click*
09:23 PM rue_mohr: maybe just where they sit with stress on them
09:30 PM Tom_L: looks a bit useless to me
09:30 PM Tom_L: and cumbersome
09:31 PM rue_mohr: you know when you set up some solder to do a joint by hand and its too short and you have to put it all down and restart?
09:31 PM Tom_L: i get plenty to start with
09:31 PM rue_mohr: either byu foot pedal or otherwise, I want it to give me a little more
09:31 PM Tom_L: i use that tiny stuff and unreel probalby 3' of it
09:32 PM Tom_L: i could see it on a reel holder hanging overhead though
09:34 PM Tom_L: i can see the guide hole in the middle being a problem too when it's pulling solder from the sides
09:35 PM Tom_L: my solder is .015" though
09:35 PM Tom_L: well one spool is anyway
09:35 PM Tom_L: the 5lb spool in the garage is .062 iirc
09:36 PM AchiestDragon: maybe if coupeled to some sort of pen type nozzle with a button so you just press the button for more solder like mig wire is depensed
09:38 PM AchiestDragon: as you still have a pause to reposition your fingers otherwise
09:40 PM rue_mohr: no, my hands are full of what I'm working on, I need the solder just *there* to use
09:42 PM z64555: I pull out a few inches of the stuff and move the workpiece to it
09:42 PM z64555: I normally work on small stuff, tho
09:42 PM rue_mohr: not when all my hands are full of what i'm working on
09:43 PM rue_mohr: I'd like a pedal or something to give me a bit more solder
09:47 PM anonnumberanon: pdf format export is crap
09:47 PM anonnumberanon: gonna try xhtml
09:48 PM anonnumberanon: oh wait no png is lovely
09:48 PM anonnumberanon: aaand png sucks as well
09:49 PM anonnumberanon: man does this export functin on LibreCalc suck heard
09:49 PM anonnumberanon: hard*
09:54 PM anonnumberanon: html export is quite nice actually, make an html file and paste this in it, then open with a browser
09:54 PM anonnumberanon: https://paste.debian.net/hidden/53a2c7b6/
09:54 PM anonnumberanon: rue_mohr, here it is
09:54 PM rue_mohr: do you remember the site I suggested you paste it to
09:56 PM rue_mohr: ah nevermind
09:57 PM Tom_L: not sure what's scheduled for tomorrow on the mill
09:57 PM Tom_L: hmm
09:57 PM Tom_L: i could cut the risers for the X axis plate
09:58 PM rue_mohr: anonnumberanon, k,
09:58 PM rue_mohr: but
09:58 PM rue_mohr: hmm
09:59 PM Tom_L: i need to remember to pin those in place
09:59 PM Tom_L: i got dowel pins just for that
10:00 PM anonnumberanon: so with that file i could also cross boxes where i feel good about the task and the material together
10:00 PM anonnumberanon: and move on
10:01 PM rue_mohr: its not how I'd suggest
10:01 PM rue_mohr: but its a method
10:01 PM rue_mohr: and what I suggest is only proven on me
10:01 PM anonnumberanon: cardboard and toothpicks, right?
10:01 PM rue_mohr: not entirely
10:01 PM * anonnumberanon ducks
10:02 PM rue_mohr: I would suggest getting a motorized cardboad dummy working
10:02 PM rue_mohr: so you can play with grbl on it
10:02 PM rue_mohr: then you have a feel for what is needed from the mechanics and your familiar with the software
10:03 PM rue_mohr: then play with building soemthing but an all out spend no money and results dont much matter
10:03 PM rue_mohr: then you know what problems you will be taking on with the expensive parts
10:03 PM rue_mohr: and you would prolly have a feel for gotchas that may come up
10:04 PM rue_mohr: for about $20 you can get a cardboard platform going, for about $40 you can make a 'scrap' machine
10:05 PM rue_mohr: for a good machine, one that I might make for $60-$80 you prolly wanna spend about $300 and use better parts
10:05 PM anonnumberanon: how many hours
10:05 PM rue_mohr: it'll cost you your life, do you want to do something else?
10:05 PM rue_mohr: ooooh, fruitfly....
10:06 PM anonnumberanon: no but seriously
10:07 PM rue_mohr: do you think you learn all the things you need to make a cnc machine, then make one and forget it all and ever make one again?
10:07 PM rue_mohr: (never make one again)
10:07 PM rue_mohr: this isn't a lesson on how to use a spoon safely
10:08 PM Tom_L: yeah those rules went out the window when someone invented the spork
10:09 PM rue_mohr: there are a lot of things you need to learn, things you need to learn you need to learn, things you dont know that you dont know
10:09 PM Tom_L: a fool is driven by what he thinks he knows
10:09 PM rue_mohr: and thats why that cardboard model just saved you over $50
10:10 PM rue_mohr: a wiseman is driven insane by all the things he knows he dosn't know, and that learning those things will make more things he dosn't know
10:10 PM anonnumberanon: this is cheap
10:10 PM anonnumberanon: https://www.homedepot.com/p/Everbilt-48-in-x-1-in-x-1-16-in-Steel-Square-Tube-801117/204225781
10:11 PM rue_mohr: 1/16"
10:11 PM rue_mohr: tom, yours is 1/4"?
10:12 PM rue_mohr: how are you at welding steel thats only 1/16" thick?
10:12 PM Tom_L: ok why?
10:12 PM Tom_L: just turn down the heat
10:12 PM rue_mohr: anonnumberanon,
10:12 PM rue_mohr: and keep moving, its a task
10:12 PM rue_mohr: dilly dally = hole
10:12 PM Tom_L: it'll twist around like a pretzel though
10:12 PM anonnumberanon: rue_mohr, pretty fucking good after doing my exhaust system and a sheetmetal project on the car
10:13 PM rue_mohr: k, you;ll need that skill
10:13 PM anonnumberanon: much sweat and tears
10:13 PM Tom_L: you may as well use cardboard if you're planning to use that 1/16" wall thickness
10:14 PM rue_mohr: I dont know $/LB for steel, at some point I put on a blindfold
10:14 PM anonnumberanon: evaluating thickness right now
10:14 PM anonnumberanon: http://www.cnczone.com/forums/diy-cnc-router-table-machines/1949-steel-square-tubing-frame.html
10:14 PM rue_mohr: it just kept going up
10:14 PM Tom_L: i don't know what the scrap guy charges per lb but it's pretty cheap
10:15 PM rue_mohr: yea, I mean new
10:15 PM Tom_L: but i got new :D
10:15 PM rue_mohr: I know scrap prices are reasonable
10:16 PM anonnumberanon: that sad feel when forget to hang measuring tape around my neck
10:16 PM Tom_L: i would hate it if i ever had to move away from my current resources
10:17 PM rue_mohr: what do you think the odds are of me being near the trigger next time that bot comes back?
10:18 PM Tom_L: huh?
10:18 PM rue_mohr: Tom_L, if your house gets taken out by a hurricane, you get a new cnc machine, right?
10:18 PM Tom_L: yeah, i'll live in a box
10:18 PM rue_mohr: or do you need a recipt
10:19 PM rue_mohr: insurace?
10:19 PM Tom_L: they'd look at it as scrap i'm sure
10:19 PM rue_mohr: awe :(
10:19 PM Tom_L: chances of getting hit by a hurricane here are slim to none
10:20 PM rue_mohr: ?
10:20 PM Tom_L: tornado maybe
10:20 PM rue_mohr: I thought you had them go by you all the time
10:20 PM rue_mohr: ok
10:20 PM rue_mohr: whatever
10:20 PM Tom_L: yeah i just smile and wave
10:20 PM rue_mohr: its ok, you didn't get hit by a hurricane, it was a tornado!
10:21 PM Tom_L: my arm's starting to itch where i set my shirt on fire the other night
10:22 PM anonnumberanon: "Less heat may not give you maximum penetration but still yeild enough strength for the job but you won't see as much aberation. I try to take advantage of this when welding and if I find that things are starting to twist I will turn up the heat and add a little extra weld in the appropriate corner to bring things back to square. Just my 2 cents..."
10:22 PM Tom_L: the sleeve was all frayed... it was an old shirt
10:22 PM anonnumberanon: Okay, got it, have a bunch of corners in the design...
10:22 PM anonnumberanon: ;)
10:23 PM Tom_L: you know if you have it normalized after welding it will all go back like it was
10:23 PM rue_mohr: and you wont really know the stuff till you have DONE it, reading lots about it wont really help
10:23 PM anonnumberanon: That tip about corners though, it's something I had already seen taught by some dude in fabrication 101 youtube.
10:23 PM Tom_L: i'm just not sure if i can do that or not
10:24 PM anonnumberanon: Tom_L, i don't know what that means
10:24 PM Tom_L: google it
10:24 PM rue_mohr: heat it all up and then weld it
10:24 PM Tom_L: it's a heat treatment to normalize the metal
10:24 PM rue_mohr: not sure what the expansion/temp graph looks like of steel, I wonder what temp it does most of its shape change at
10:24 PM Tom_L: pretty hot
10:25 PM Tom_L: normalizing is a dull red glow i think
10:25 PM rue_mohr: bonfire
10:25 PM rue_mohr: but on the granite :)
10:25 PM rue_mohr: casue you dont want it normalizing to crookid
10:26 PM Tom_L: if i had a pottery kiln big enough that would work great
10:26 PM rue_mohr: there may be a bunch of creasote soaked wood standing upright along the side of the road
10:26 PM rue_mohr: it burns hot
10:27 PM rue_mohr: try to not mind the pesky wires attached to the top
10:27 PM anonnumberanon: see so far iv only done welding on painful af thin af exhaust pipes, and under the car, or out but welding 2 different metals together including one being cheap af metal that is a pita to weld, so i think this will be a breath of fresh air compared
10:27 PM anonnumberanon: really looking forward to it
10:28 PM Tom_L: what sort of welder do you have?
10:28 PM anonnumberanon: now i have a mig
10:29 PM Tom_L: rue_mohr, i'm still working off that first tank of gas
10:29 PM anonnumberanon: this one https://www.homedepot.com/p/Lincoln-Electric-88-Amp-Handy-MIG-Wire-Feed-Welder-with-Gun-MIG-and-Flux-Cored-Wire-Hand-Shield-Gas-Regulator-and-Hose-115V-K2185-1/100596739
10:29 PM Tom_L: flux core sucks the big one
10:30 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/Miller.jpg
10:30 PM Tom_L: there's mine
10:31 PM Tom_L: that's more a body shop welder
10:31 PM Tom_L: thin metal
10:32 PM anonnumberanon: can i use something else than flux core wire?
10:32 PM Tom_L: you need shield gas if you do
10:32 PM anonnumberanon: ok
10:32 PM anonnumberanon: good
10:32 PM Tom_L: i use 75/25 argon / co2
10:33 PM anonnumberanon: really looking forward to amortizing this welder
10:33 PM Tom_L: flux core spatters way too much
10:33 PM Tom_L: and it's reverse polarity from regular wire
10:33 PM Tom_L: regular wire is + anode
10:34 PM anonnumberanon: uh yeah, i need to change that?
10:34 PM anonnumberanon: reverse the connections near the wire roll inside?
10:36 PM rue_mohr: I got 1000 green and 1000 red leds today 0805
10:36 PM rue_mohr: ... I dont know what their for... maybe its just stock
10:37 PM Tom_L: anonnumberanon you need to figure out what it requires
10:37 PM Tom_L: generally it's + anode for regular wire on steel
10:37 PM anonnumberanon: rue_mohr, i vaguely remember you ordering them months ago
10:37 PM anonnumberanon: lol
10:37 PM Tom_L: unless you're using some exotic stuff
10:38 PM Tom_L: i've got a spool of flux core and it will likely stay in it's shrinkwrap until i leave this earth
10:40 PM Tom_L: i got it once when i was helping a friend with his trailer. we were welding outside and i thought i might need it there
10:47 PM anonnumberanon: all they have at Home Depot is 1/16" wtf
10:47 PM anonnumberanon: gotta find some kind of metal shot
10:47 PM anonnumberanon: shpo
10:47 PM anonnumberanon: shop

10:49 PM armyofevilrobots: Not bad for cad -> reality in a couple hours.
10:50 PM Tom_L: what cnc did you cut it on?
10:51 PM armyofevilrobots: @Tom_L CNC? This was done by hand. Hacksaw, gauge blocks, belt sander.
10:52 PM armyofevilrobots: Oh, and dial indicator and calipers.
10:52 PM Tom_L: nice
10:52 PM anonnumberanon: armyofevilrobots, what's the gauge block, the steal cubes with a bunch of holes in it everywhere?
10:52 PM armyofevilrobots: Hahaha. The motor mount was already built. I only built the top plate tonight.
10:53 PM Tom_L: oh
10:53 PM Tom_L: for the rails
10:53 PM armyofevilrobots: @anonnumberanon That’s a 123 block, but same thing, just thinner.
10:53 PM Tom_L: btw, do the bearings stay in those when they're off the rails?
10:53 PM Tom_L: mine came with plastic inserts
10:53 PM Tom_L: i didn't know if that was just for shipping or what
10:53 PM armyofevilrobots: The rails are mgn30s, and yes, the rails have plastic retainers that you don’t have to remove when installing on the rails.
10:54 PM armyofevilrobots: It came with plastic blocks that hold the bearings in too, but I didn’t need those. The bearings are in there nice and firm.
10:54 PM armyofevilrobots: Don’t try that with a ballscrew though ;)
10:55 PM armyofevilrobots: Got the wrong length socket head screws tho. Gotta go back to get 5mm longer tomorrow.
10:55 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Z_Axis_Plate2.jpg
10:55 PM Tom_L: like that black plastic in that one
10:55 PM Tom_L: i was hesitant to take it out before i mounted it to the rail
10:55 PM anonnumberanon: ah thanks armyofevilrobots
10:56 PM Tom_L: yeah, i gotta cut a ballscrew down. i just figured i'd tape it up real good to protect it
10:56 PM anonnumberanon: it's too tall?
10:56 PM Tom_L: i made a coupler to fit over it to clamp in the lathe
10:57 PM Tom_L: too long
10:57 PM armyofevilrobots: @Tom_L Yep, exactly. Mine are red in color, but otherwise idential.
10:57 PM armyofevilrobots: Oooh. What spindle are you using?
10:57 PM Tom_L: i'm not sure what i'll end up with yet but i'm gonna start with the sherline one

10:59 PM Tom_L: something along those lines i suppose
11:05 PM rue_mohr: Tom_L, what peak speed are you aiming for when done?
11:05 PM Tom_L: speed?
11:05 PM rue_mohr: you had a time with that on your sherline
11:05 PM Tom_L: spindle?
11:05 PM rue_mohr: rpm
11:05 PM armyofevilrobots: I’ve been looking at toolchange router spindles, but my wife is resistant sin ce they r un 3kUSD+
11:05 PM Tom_L: probably around 6-8k
11:05 PM armyofevilrobots: The BT30 ones are a lot cheaper since they run under 10krpm.
11:05 PM Tom_L: yeah i'd have a hard time getting that past management too
11:06 PM rue_mohr: Tom_L, aren't you using 20k on the sherline?
11:06 PM Tom_L: around 5-6
11:06 PM Tom_L: tops
11:06 PM rue_mohr: oh, thought you repullied it for high rpm
11:06 PM Tom_L: but i usually run around 2000 to 3000
11:06 PM Tom_L: that is high for that spindle
11:06 PM rue_mohr: so, you couldn't cut aluminum any faster than I am
11:07 PM rue_mohr: armyofevilrobots, whats your min spindle speed?
11:07 PM Tom_L: why not?
11:07 PM Tom_L: i will be able to use larger cutters
11:07 PM rue_mohr: Tom_L, rpm
11:07 PM Tom_L: with less chatter
11:07 PM armyofevilrobots: @rue_mohr 10krpm. But it’s a router. Totally different situation.
11:07 PM rue_mohr: yea
11:08 PM Tom_L: yeah i don't want a bazillion rpm router head on it
11:08 PM rue_mohr: armyofevilrobots, will your bits plug up with alum at min speed?
11:08 PM armyofevilrobots: Depends on the bit, but yes.
11:08 PM rue_mohr: at a particular point I think there is just too much heat
11:08 PM Tom_L: if you go to slow
11:08 PM Tom_L: or too fast
11:08 PM armyofevilrobots: I’ve had some success with really thin passes.
11:09 PM armyofevilrobots: BUt Aluminum is gooey, and wants to grab, and the gantry isn’t really rigid enough to take the right depth of cut, so…
11:09 PM rue_mohr: that last one I made can do up to 12krpm, I'm using .2 -.25mm passes
11:09 PM rue_mohr: but at about 17mm/min
11:09 PM armyofevilrobots: I would love to get a proper metalCNC too, but not for a while...
11:09 PM Tom_L: we were discussing efficiency in another channel and the guy says that taking thin cuts but deeper is more efficient than wider shallow cuts
11:09 PM rue_mohr: keep in mind I have a mill
11:09 PM Tom_L: higher production
11:10 PM armyofevilrobots: @Tom_L Yeah, I misstated it. I meant shallow depth of cut. The bits I use are either 1/8 or 1/4 for aluminum.
11:10 PM Tom_L: yeah
11:10 PM Tom_L: most of mine for the sherline are small too
11:10 PM rue_mohr: I'm still adjusting feed rates
11:10 PM armyofevilrobots: And pretty similar depth of cut as @rue_mohr.
11:11 PM armyofevilrobots: Maybe .5 mm at most on the gantry, otherwise it gets vibrating.
11:11 PM Tom_L: that's why i'm building this one
11:11 PM Tom_L: to help with vibration etc
11:11 PM armyofevilrobots: Those BTC spindles look pretty solid.
11:12 PM armyofevilrobots: er. bt30. %@!# bitcoin is in my muscle memory now.
11:13 PM orlock: armyofevilrobots: there was a guy in australia who claimed to be satoshi
11:13 PM orlock: armyofevilrobots: i wonder how long until he gets dragged off in the middle of the night
11:13 PM armyofevilrobots: Yeah, I figure anybody that _is_ satoshi doesn’t wanna advertise. especially now that he is basically a trillionaire.
11:13 PM Tom_L: you'd have to have a cylinder for the drawbar
11:13 PM armyofevilrobots: We’re just looking at blockchain for distributed billing systems.
11:13 PM orlock: never to be heard of again
11:14 PM orlock: armyofevilrobots: this guy got taided by the tax office soon afterwards
11:14 PM orlock: armyofevilrobots: he never actually prooved it, his name is mud now apparently
11:14 PM armyofevilrobots: but all this blockchain stuff looks to have aggregate transaction rate issues. I am no expert, but it seems like it isn’t really viable except as an investment vehicle.
11:14 PM armyofevilrobots: hahaha. That’ll learn him.
11:15 PM armyofevilrobots: OK, time to go start on gantry mount #2….
11:15 PM orlock: armyofevilrobots: yeah, how to you prevent issues with the blockchain size ballooning if you actually, you know, use it
11:15 PM armyofevilrobots: Then tomorrow I can build the X axis one, which is crazy complex.
11:15 PM armyofevilrobots: exactly, and also DOSing everybody else using the blockchain.
11:15 PM armyofevilrobots: when those transaction rates go up, it’s gonna be hard to get transactions confirmed, and I bet there are real-world protocol issues before you get to the theoretical maximums.
11:16 PM armyofevilrobots: but again, I am no expert in BTC.
