#robotics Calendar
12:07 AM rue_mohr: you didn't hot glue a 1w+ led?
12:12 AM rue_shop3: oh, and there's one in EACH of the robot arms
12:14 AM Jak_o_Shadows: I mean, technically the ebay item listing doesn't have a wattage
12:14 AM Jak_o_Shadows: Practically, it's about 5W?
12:14 AM Jak_o_Shadows: 120 little leds
12:21 AM rue_shop3: I used up all the 'cheap' pro minis
12:21 AM rue_shop3: :/
12:22 AM Jak_o_Shadows: I might have fried the voltage reg on this stm32 blue pill
12:23 AM rue_shop3: why is everyone trying to make debuggers and logic analizers?
12:23 AM rue_shop3: dont use the blue pill, use a freaking io port
12:23 AM Jak_o_Shadows: who is everyone?
12:26 AM Jak_o_Shadows: ?
12:26 AM rue_shop3: its all I'v heard about this week
12:26 AM Jak_o_Shadows: I'm trying to make an alarm clock torch.
12:26 AM Jak_o_Shadows: I think installing it in circuit has somehow buggered up the LSE.
12:29 AM Jak_o_Shadows: and on this one, potentially the 3.3V voltage reg
12:29 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base3.jpg
12:29 AM Tom_L: did a little more
12:29 AM rue_shop3: therego
12:29 AM Jak_o_Shadows: oh, and I bought an oscope
12:29 AM rue_shop3: I still say pull those uprights in 1/4" on each side and slip in a plate
12:29 AM Tom_L: i didn't have time to figure that out tonight
12:29 AM Jak_o_Shadows: can't have fried the 3V3, it works when you power it via usb
12:29 AM Tom_L: but it's on the list
12:45 AM Jak_o_Shadows: yup. 'twas rubbish soldering
12:45 AM Jak_o_Shadows: I'll check out the oscillator when my oscilloscope arrives
01:06 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base3_Brace.jpg
01:06 AM Tom_L: rue_shop3
01:06 AM Tom_L: x2
01:12 AM rue_shop3: ah
01:12 AM rue_shop3: how about bringing in the posts and lapping them in instead of the ~but weld
01:12 AM Tom_L: i could
01:15 AM Tom_L: updated that pic
01:16 AM rue_shop3: ah yes
01:18 AM Tom_L: Y screw is too long
01:18 AM Tom_L: because i can only get enough travel to where the table hits the Z upright
01:18 AM rue_shop3: I want to see how you take on X
01:18 AM Tom_L: probably around 12" maybe
01:18 AM Tom_L: i bet you do
01:19 AM Tom_L: i'm thinking an aluminum plate ~1" thick
01:19 AM Tom_L: milled rectangle and grid of holes
01:21 AM rue_shop3: the new pendant is comming along nicely
01:21 AM rue_shop3: printed keyboard and cdrom motor for an encoder, which fixes up the two unique pieces I used on the origional
01:22 AM Tom_L: gotta get up in 5 hrs so gnite
01:23 AM rue_shop3: gngiht
01:23 AM Tom_L: got steppers comin for it
01:23 AM rue_shop3: k
01:23 AM Tom_L: no rails yet
01:23 AM Tom_L: 570 in oz
01:23 AM Tom_L: beefy
01:24 AM rue_shop3: :) see how the speed ratio goes
01:24 AM rue_shop3: it depends on the spindle
01:24 AM rue_shop3: tho , fast jogging is nice
01:24 AM Tom_L: 1:1 would be too much
01:24 AM Tom_L: since right now my screw is 20 tpi an the ballscrew is 5
01:25 AM Tom_L: so maybe a 3-4-5:1 reduction
01:25 AM Tom_L: somewhere in there
01:25 AM Tom_L: may have you print some stuff for me
01:25 AM Tom_L: belt covers
01:25 AM rue_shop3: yup
01:26 AM Tom_L: i'll see how it all comes together first
01:26 AM Tom_L: gnite
01:26 AM rue_shop3: night
01:26 AM Tom_L: prolly get to work on it tomorrow some
01:27 AM * rue_shop3 should send tom a vertex kit for a 3d printer and a meter of filament
01:30 AM rue_shop3: :/ only 11pm and I'm yawning
01:30 AM rue_shop3: zhanx, hey, you finish those 4 pieces?
01:30 AM zhanx: thought it was 8 and yes
01:30 AM rue_shop3: 8!? you keep remembering the numbers wrong
01:31 AM rue_shop3: ?
01:31 AM rue_shop3: I cant remmeber, were not on a roll
01:32 AM rue_shop3: hows life anyhow? find any new work?
01:36 AM rue_shop3: zhanx, do you have any of the 8mm ground rod they use in printers for sliders? say, 6 pieces?
01:39 AM rue_shop3: I think my get-up-and-go went to bed :/
02:34 AM anonnumberanon: god-tier new Debian Buster installation here
02:34 AM anonnumberanon: on 1920p laptop
02:34 AM anonnumberanon: feelsgudman
03:54 AM rue_mohr: sweeeeeeeeeeeeeeeeeeeeeet my offset line function works
03:55 AM rue_mohr: Line is : 2.000, 2.000 -> 4.000, 4.000
03:55 AM rue_mohr: Offset by 1.414 line is : 1.000, 3.000 -> 3.000, 5.000
03:55 AM rue_mohr: was it 1.000, 3.000 -> 3.000, 5.000 ?
03:55 AM rue_mohr: its left handed, a positive offset moves the line to the left if standing on the first point and looking at the second
04:22 AM anonnumberanon: :3
11:38 AM rue_bed: starting to think it would be generally usefull to switch between polar and cartesian space alltogethor for operations
11:41 AM rue_bed: things like changing the length of a line, or making a perpedicular-offset line thats easier to do in polar
11:43 AM rue_bed: and I'v been thinking of vectors too
11:44 AM rue_bed: having an equiv of a line segment in vector
11:44 AM rue_bed: dont need it for anyhing yet
12:32 PM rue_mohr: movement requires a reference thats stable from the axies you want to travel, to travel in time you need something that dosn't change with time, such as a watched pot of water, thus, a watched pot of water is an important element to time travel
12:32 PM robotustra: rue_mohr, are you talking to yourself?
12:35 PM rue_mohr: sure
12:35 PM rue_mohr: but only when nobody else is talking
12:37 PM robotustra: did you make something interesting to show?
12:41 PM rue_mohr: just 2 C functions
12:45 PM robotustra: embedded into the robot?
12:46 PM rue_mohr: no
12:46 PM rue_mohr: part of my 2d library for stuff, like CAD
12:46 PM rue_mohr: and CAM
12:53 PM Tom_L: wonder how to disable defender
12:54 PM rue_mohr: install linux, as the only OS
12:55 PM rue_mohr: no split boot
12:55 PM Tom_L: i'd lose 3/4 of my programs if i did
12:55 PM rue_mohr: or ask a hacker, I'm sure its easy
12:55 PM weyland|yutani: use virtual machines?
12:56 PM rue_mohr: my 2d lirary is comming along, I should start working on the cam software again
12:57 PM weyland|yutani: with KVM under linux you even can pass a real graphics through ti use with a virtual machine
12:57 PM weyland|yutani: graphics card
01:02 PM Tom_L: ok rue_mohr
01:03 PM Tom_L: what improvements do you see to make on the mill?
01:03 PM Tom_L: need a shorter Y screw
01:03 PM Tom_L: won't ever be able to use that much travel
01:09 PM rue_shop3: latest image?
01:10 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base3_Brace.jpg
01:10 PM Tom_L: looks skewed but it's the angle it was when i snapped it
01:11 PM Tom_L: see even with a motor on the Z, it barely reaches the far edge of Y
01:11 PM Tom_L: i haven't figured the motor thickness yet
01:11 PM Tom_L: but it should be close
01:12 PM Tom_L: so the table can travel out to the near edge and that's all the effective travel
01:19 PM tttb2 is now known as tttb
01:19 PM rue_shop3: the uprights will need caps to maintain their stability along the x axis
01:20 PM rue_shop3: Y motor at the back, right?
01:20 PM rue_shop3: aka, the leadscrew is shown backwards?
01:20 PM robotustra: < Tom_L> i'd lose 3/4 of my programs if i did
01:20 PM * rue_shop3 tries to grab and rotate the 2d image
01:21 PM robotustra: install linux, virtual box and run all your windows stuff inside virtual box
01:21 PM robotustra: you'll get virus protection and you'll have all your windows toolchain
01:22 PM robotustra: and it's will be very easy to backup your system and transfer it to other PCs
01:24 PM robotustra: Tom_L, is it your future machine?
01:25 PM rue_shop3: Tom_L, ?
01:26 PM robotustra: I see stantard chineese elements
01:26 PM robotustra: like rails and screws
01:26 PM robotustra: and why only 2 DOF? where is the third axis?
01:28 PM robotustra: I'm also going to make a lathe...
01:29 PM robotustra: got some tools https://i.imgur.com/JJkE4al.jpg
01:30 PM rue_shop3: :)
01:31 PM robotustra: now I have a stone to pray
01:37 PM rue_shop3: pray its straight
01:38 PM rue_shop3: Tom_L, did you dissapear?
01:38 PM rue_shop3: still want to see how the X axis is going to work
01:57 PM Tom_L: had to pick somebody up
01:57 PM Tom_L: and went out to measure the sherline spindle head
01:58 PM Tom_L: robotustra it's a work in progress
01:58 PM Tom_L: just started a couple days ago or so
01:59 PM Tom_L: i may get to X today, maybe maybe not
02:16 PM robotustra: why do you need to tilt Z? or it's for adjustment?
02:17 PM Tom_L: just to make it square
02:28 PM robotustra: "if you can't make it precise - make it adjustable" (c)
02:28 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base3_Spindle.jpg
02:28 PM Tom_L: once i figure out where the spindle head needs to be, i'll raise that column and probably shorten it
02:29 PM Tom_L: but i need more travel in Y than that
02:29 PM Tom_L: so i'm gonna redo the Z axis a bit
02:29 PM Tom_L: that's a sherline head btw
02:29 PM robotustra: I would make a triangle to keep Z righd
02:29 PM Tom_L: clear to the top, yes
02:30 PM Tom_L: and make the slot in it for adjustment
02:30 PM Tom_L: maybe a 2x2 beam instead of plate
02:30 PM Tom_L: it's gonna get kinda heavy though
02:30 PM Tom_L: it's thickwall 2" square tube
02:30 PM robotustra: 0.25" of thickness?
02:31 PM Tom_L: .179 iirc
02:31 PM robotustra: I'll use 1/4" for mine
02:31 PM Tom_L: not sure you can buy standard 2" square tube that thick
02:31 PM Tom_L: this is standard thickwall
02:32 PM Tom_L: it's pretty heavy
02:35 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base3_Spindle2.jpg
02:35 PM Tom_L: different angle
02:35 PM Tom_L: that Z plate is way too big though
02:35 PM Tom_L: i may just use 1 set of blocks on it instead of 2
02:35 PM Tom_L: but 2 makes it stiffer
02:36 PM robotustra: https://imgur.com/UmR8ib4
02:36 PM robotustra: 2x2x0.25"
02:37 PM Tom_L: wall isn't very consistent
02:37 PM Tom_L: is that extruded?
02:37 PM Tom_L: or rolled
02:37 PM robotustra: I think rolled
02:37 PM Tom_L: ours are all rolled and seam welded
02:37 PM robotustra: it is
02:38 PM Tom_L: it will get heavy real quick
02:38 PM robotustra: what is heavy for stationary parts?
02:38 PM Tom_L: i haven't calculated mine
02:38 PM Tom_L: but i bet it'll be in the 2-300 lb range
02:38 PM robotustra: Tom_L, how many machines did you already build?
02:39 PM Tom_L: before it's done
02:39 PM Tom_L: none
02:39 PM Tom_L: i have a sherline
02:39 PM Tom_L: want a more beefy one
02:39 PM Tom_L: so anything i do will improve on that
02:39 PM robotustra: have a pic of sherline?
02:40 PM robotustra: my mill is about 100 lb
02:40 PM robotustra: made from al
02:40 PM robotustra: may by I'll remake it in 10 years
02:41 PM Tom_L: i do but i'll have to dig
02:41 PM robotustra: but as soon as precision good - I'll use it
02:41 PM robotustra: nevermind
02:42 PM robotustra: ah, I got it
02:42 PM Tom_L: https://www.youtube.com/watch?v=g99lUtjLfMU&feature=youtu.be
02:42 PM robotustra: something like this? http://sherline.com/product/85408541-complete-cnc-mill/
02:43 PM Tom_L: mine is the 2000
02:43 PM Tom_L: extended neck on Y
02:44 PM robotustra: here it's mine https://www.youtube.com/watch?v=BwhQ6ab06e0
02:45 PM robotustra: if I could I would make it from steel
02:47 PM robotustra: and may be fixed the portal and made moving table along X
03:01 PM Tom_L: my welding skills will be tested
03:01 PM Tom_L: i haven't done much for quite a while
03:02 PM Tom_L: i learned on stick and now have wire feed and it's just not the same
03:04 PM robotustra: welding skills a good, but it can curve the machine
03:14 PM Tom_L: may try to have it flattened afterward
03:14 PM Tom_L: aka bridgeport
03:15 PM robotustra: yes
03:16 PM robotustra: go out
04:24 PM robotustra is now known as robotustra_
04:27 PM robotustra_ is now known as robotustra
04:58 PM henriksod1 is now known as henriksod
04:59 PM evilroot: Dang that Sheline is expensive for what it is
05:03 PM Tom_L: yeah they're kinda high
05:03 PM Tom_L: mine's old
05:09 PM evilroot: My Seiko bots blow that out of the water, heh
05:18 PM robotustra: evilroot, what is Seiko bot?
05:19 PM Tom_L: commercial arm
05:19 PM Tom_L: probably
05:43 PM evilroot: https://images.craigslist.org/00U0U_49lRDkBG89p_1200x900.jpg
05:43 PM evilroot: https://images.craigslist.org/00K0K_hhj6sJhnL4x_1200x900.jpg
05:43 PM evilroot: Tom_L: commercial Cartesian
05:43 PM evilroot: Super beefy :-D
05:46 PM evilroot: I originally had 14 of them in various sizes . . . . down to 5 now
05:47 PM evilroot: My shop only has room for 3, I use them for various milling stuff
05:50 PM robotustra: what is the precision?
05:51 PM evilroot: 60 micron X/Y
05:51 PM evilroot: 40 Z
05:52 PM evilroot: Move speed of 1000mm/sec
05:52 PM evilroot: They're beasts, heh
06:06 PM robotustra: to mill plastic mey be good
06:06 PM robotustra: may*
06:08 PM evilroot: I mill aluminum with them
06:08 PM robotustra: what thikness?
06:09 PM evilroot: Whatever I want . . . . speed and depth depend on the tool
06:10 PM robotustra: is it your own?
06:10 PM evilroot: Toolhead payload of 15kg . . . that will mount one HELL of a spindle
06:10 PM evilroot: Yeah, I own them
06:10 PM evilroot: Got them at an auction a while back. They were a lot so I had to buy 14 total
06:10 PM robotustra: so you do not need to build any cnc mill then
06:10 PM evilroot: Over the last year I've sold 9
06:11 PM evilroot: That's funded me outfitting my three :-)
06:12 PM robotustra: do you have an enterprise?
06:12 PM evilroot: Still have two left for sale, both 600x400x200mm 4 axis units
06:12 PM evilroot: Enterprise? As in business?
06:12 PM robotustra: yeah, own business
06:13 PM evilroot: Yes
06:13 PM robotustra: what do you manufacture?
06:13 PM evilroot: Various electronic and physical components for certain companies
06:13 PM evilroot: Can't say much more beyond that due to contracts
06:14 PM robotustra: are you the BOSS in the company?
06:16 PM evilroot: I own it, yeah
06:16 PM evilroot: If you or Tom_L want a better machine you ought to grab one of the two I have left, heh
06:16 PM robotustra: is it a big company?
06:16 PM evilroot: Naw really small. Just me usually
06:17 PM robotustra: :)
06:17 PM robotustra: I'm thinking regularly about own company
06:17 PM evilroot: Not much to it really
06:18 PM robotustra: but not today, may be in 5 years
06:18 PM evilroot: Cost $300 to have a lawyer write up the paperwork, plus another $100 or so in fees
06:18 PM evilroot: And boom I had a company
06:18 PM robotustra: no, I'm not talking about formalities
06:19 PM robotustra: it canada I can work as selfemployed without any formalities
06:19 PM robotustra: and the company name == my tax payer name
06:22 PM evilroot: You can here too
06:23 PM evilroot: But having a corporation has various legal and tax benefits
06:23 PM evilroot: Plus I can hire employees if needed
06:28 PM Tom_L: no room for one here
06:29 PM Tom_L: S corp LLC or C corp?
06:29 PM Tom_L: C sucks
06:31 PM robotustra: what are the differences ?
06:31 PM Tom_L: quite a bit, mostly the way they're taxed
06:33 PM robotustra: can canadian register a company in USA?
06:33 PM evilroot: Mine is an LLC
06:34 PM Tom_L: companies do that for foreign benefits but that sort of thing may be changing
06:34 PM Tom_L: mine is S
06:34 PM Tom_L: LLC is farily new
06:34 PM robotustra: what is the diff?
06:34 PM Tom_L: similar
06:35 PM Tom_L: LLC is basically a liability blanket
06:35 PM evilroot: LLC is better for a single owner, or at least simpler
06:36 PM evilroot: My first business was a C corp, second was S
06:36 PM evilroot: This is my third
06:37 PM robotustra: where are your previous companies?
06:38 PM evilroot: The first was buying and then refurbishing/fixing fixing equipment for resale
06:38 PM evilroot: Pretty much anything that was broken I would fix, from laptops to TVs to medical equipment
06:38 PM evilroot: Then I opened a retail electronics repair store
06:39 PM robotustra: was is profitable enough to live?
06:39 PM evilroot: But my business partner and I had a big falling out
06:39 PM evilroot: I left and now I have my own personal office and shop
06:40 PM evilroot: Yeah, profitable enough to live decently
06:40 PM evilroot: This current one isn't a ton of money now, but its also very new
06:40 PM robotustra: yeah, from this point of view it's easier to be the only founder and owner
06:40 PM robotustra: you can't disagree with yourself
06:43 PM robotustra is now known as robotustr0
06:44 PM evilroot: Yeah
06:44 PM evilroot: He and I had very different approaches
06:45 PM evilroot: I actually almost shipped a bot to a guy in Canada
06:51 PM robotustr0: so you didn't produce anything? just did repairs?
06:52 PM robotustr0 is now known as robotustra
06:58 PM robotustra is now known as robotustr0
06:59 PM evilroot: Yep
06:59 PM robotustr0 is now known as robotustra
07:00 PM evilroot: I really enjoy fixing things
07:00 PM evilroot: But now I'm making stuff
07:00 PM evilroot: Also working on my own original design for a 3d printer
07:01 PM robotustra: how do you get orders to do something?
07:02 PM robotustra: how ppl find you to make an order to your company?
07:03 PM robotustra: evilroot, to make design is easy, to set up a production - is not so easy
07:09 PM evilroot: That's why I have industrial robots . . .
07:10 PM evilroot: As for orders/etc I have a bit of a reputation
07:10 PM evilroot: For doing the stuff other companies charge tons of money and require a whole team to accomplish
07:10 PM evilroot: A lot faster and cheaper, heh
07:14 PM robotustra: yeah, but you have to find clients somehow from the very beginning
07:14 PM robotustra: how did you that?
07:15 PM robotustra: how long does it take to find first clients?
07:17 PM durrf: depends on the market, depends on where you are, depends on how effective any advertising you do is
07:21 PM robotustra: durrf, I was asking evilroot about his business in particular
07:22 PM robotustra: not theory
07:22 PM durrf: b gut
07:25 PM evilroot: Some clients I've had from back when they bought equipment from me
07:25 PM evilroot: I got a lot through the store too
07:25 PM evilroot: We were famous for fixing stuff other places couldn't
07:25 PM evilroot: And a lot of customers went to have me do other work for them onsite and such
07:26 PM evilroot: NC State's IT dept would bring stuff they couldn't fix to us, heh
07:28 PM robotustra: you mean you fix electronix, not mech stuff?
07:41 PM evilroot: I fixed EVERYTHING
07:42 PM evilroot: But now I do robotics, linear motion systems, 3d printing, and circuit design
07:42 PM evilroot: Currently only one of my robots is actively milling. Another is halfway done
07:43 PM evilroot: After I sell these last two I'll be able to move to full production
07:43 PM evilroot: Then I'll start making 3d printers. The prototypes have worked great
07:44 PM evilroot: I'm milling most of the parts from aluminum
07:52 PM robotustra: how much is you 3d printer costs?
07:54 PM robotustra: evilroot, what are robots for?
07:57 PM evilroot: Like I said, I use them for milling and production
07:57 PM evilroot: (The Seiko ones)
07:57 PM evilroot: Haven't decided on a price for my printer yet
08:00 PM robotustra: ah, I thought that you are making 2 new robots :)
08:00 PM robotustra: what programm do you use to control your robots?
08:00 PM evilroot: LinuxCNC
08:00 PM robotustra: any adapters to connect?
08:01 PM robotustra: what board do you use to connect robots to pc?
08:04 PM evilroot: https://www.amazon.com/SainSmart-Breakout-Board-Stepper-Driver/dp/B0093Y897A/ref=sr_1_5?ie=UTF8&qid=1509237144&sr=8-5&keywords=parallel+breakout+board
08:04 PM evilroot: This
08:04 PM evilroot: Plus 4 Geckodrive G320X servo drivers
08:07 PM robotustra: what torque does servos give?
08:07 PM robotustra: ah, it's drives
08:08 PM robotustra: driver
08:08 PM robotustra: a
08:08 PM robotustra: and what steppers do you use?
08:12 PM Tom_L: i got some big honkers comin
08:13 PM evilroot: Not steppers
08:13 PM evilroot: Servos
08:14 PM evilroot: 70V brused DC servos
08:14 PM evilroot: *brushed
08:14 PM evilroot: Not sure on the exact torque off the top of my head, but LARGE
08:14 PM evilroot: heh
08:14 PM evilroot: The Y axis uses a 500W servo, X 350W
08:15 PM evilroot: Tom_L: big wha?
08:15 PM Tom_L: oh i got some steppers comin
08:16 PM evilroot: For a spindle I use a 2.2kW air cooled
08:16 PM Tom_L: will fit the sherline but would probably twist it up in a ball
08:16 PM evilroot: NEMA 34?
08:16 PM Tom_L: naw, not that big
08:16 PM Tom_L: just some nema 23 570 in oz
08:17 PM evilroot: The really big router at the warehouse I'm in uses NEMA 42's
08:17 PM evilroot: But its like 18x8'
08:17 PM Tom_L: but it's got 282 in oz on it right now which replaced some 135's that were on it originally
08:17 PM evilroot: Tom_L: you should buy a robot and get real power, muahahaha
08:17 PM Tom_L: but i'm gettin these really for the new build
08:17 PM Tom_L: no room
08:17 PM evilroot: Meh, they're not that big
08:18 PM Tom_L: i've seen a bunch of em
08:18 PM evilroot: I have three in a 250sq ft room
08:18 PM Tom_L: they have a whole room full at the vo-tech here
08:18 PM Tom_L: from small to large
08:18 PM evilroot: Cartesians have a much smaller footprint
08:19 PM evilroot: They'll fit on a mornal desk
08:19 PM Tom_L: yeah i know what you mean
08:19 PM Tom_L: i'm working on a budget here though
08:19 PM evilroot: These last two I'm doing for $800 each
08:19 PM Tom_L: granted it's not a rue_mohr budget but still...
08:20 PM evilroot: I'd prob get more parting them out, but can't bear to do that heh
08:20 PM Tom_L: i've got $20 in iron invested in this thing so far
08:20 PM Tom_L: i'll re'use the control box
08:20 PM Tom_L: so all i'm out is the steppers and rails
08:21 PM Tom_L: trying to decide how to brace this thing
08:25 PM robotustra: I'll use this motor for the lathe https://www.ebay.com/itm/NEMA23-Hybrid-Closed-Loop-Stepper-Servo-Motor-Drive-Kit-1NM-Encoder-IHSS57-36-10/121792621792
08:26 PM robotustra: 1 N*m
09:57 PM rue_shop3: not for the spindle?
10:13 PM Tom_L: pics to come
10:18 PM rue_shop3: my unsorted stuff box count is getting silly
10:18 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base3_Brace.jpg
10:18 PM robotustra: rue_shop3, use Mary Condo method of cleaning
10:19 PM rue_shop3: k
10:19 PM robotustra: much better
10:19 PM rue_shop3: Tom_L, how about a corner view
10:19 PM rue_shop3: my mind is failing
10:20 PM robotustra: add andles to the Z axis
10:20 PM robotustra: below the hirizontal tube
10:20 PM robotustra: rue_shop3, train your brain :)
10:21 PM robotustra: spindle looks small
10:21 PM rue_shop3: just a bearing I think
10:21 PM rue_shop3: motor not shown
10:22 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base3_Brace_table%20extended.jpg
10:22 PM Tom_L: one sec, for angle
10:24 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base3_Brace2.jpg
10:25 PM Tom_L: thoughts?
10:25 PM robotustra: or you can fill the gap between horizontal and vertical tubes with a rectangular bar
10:25 PM Tom_L: i have a model with a short Z table using just 2 slides, one on each side
10:26 PM robotustra: this one is good
10:26 PM Tom_L: leave 4 slides?
10:27 PM Tom_L: they come with 2 ea anyway
10:27 PM Tom_L: i need to shorten the base some
10:27 PM Tom_L: and figure out where to put the steppers
10:27 PM robotustra: 2 slides on a rail is ok
10:28 PM robotustra: I have to draw my own lathe
10:28 PM Tom_L: those plates will probably be aluminum anyway
10:28 PM Tom_L: now for what rue's been waiting for
10:28 PM Tom_L: X
10:29 PM robotustra: so you'll not put axis on the bottom of Z stand?
10:30 PM Tom_L: don't follow what you mean
10:30 PM robotustra: what is the precision are you planning for this machine
10:30 PM Tom_L: X will go on top of Y
10:30 PM Tom_L: 1" +- .5"
10:30 PM Tom_L: :)
10:31 PM Tom_L: i'll work it out as i go
10:31 PM robotustra: you made a adjusting slide on the back, but the Z stand has no tilt mechanism
10:31 PM Tom_L: i didn't draw that
10:31 PM robotustra: ok
10:31 PM Tom_L: basically a bolt thru the sides on each side
10:31 PM rue_shop3: the more it looks like an arbour press the better
10:31 PM robotustra: you are puching me to draw my lathe in the CAD :)
10:32 PM Tom_L: GOOD!
10:32 PM Tom_L: it makes planning cheap
10:32 PM Tom_L: and mistakes more forgiving
10:32 PM rue_shop3: Tom_L, whats the mode that causes the edge lines instead of just shading?
10:32 PM Tom_L: so i can shorten the base by the amount you see from the Y table to the end
10:32 PM robotustra: not really, I already got all slides and chuck + all other stuff
10:33 PM robotustra: and I did draw it on a paper
10:33 PM Tom_L: rue_shop3, i'm not sure. i can do it but don't do it often enough to remember
10:33 PM rue_shop3: cause I cant turn it on :)
10:34 PM Tom_L: what do you prefer?
10:34 PM rue_shop3: I wanted to make some assembly diagrams, but can only get shaded models
10:34 PM rue_shop3: wanted something that looks drawn
10:34 PM robotustra: https://imgur.com/nc1oTls
10:35 PM robotustra: https://imgur.com/1SnzHID
10:36 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base3_Brace2_Shaded_For_Rue.jpg
10:36 PM Tom_L: jeeze
10:36 PM robotustra: looks like cnc mill
10:36 PM Tom_L: now to work on X
10:37 PM robotustra: what CAD is it?
10:37 PM Tom_L: catia
10:37 PM Tom_L: i'm using SW for parts of it
10:37 PM Tom_L: some models i can't get so i import them
10:37 PM Tom_L: like bearings etc
10:37 PM rue_shop3: yea, I need to know what the line feature is called
10:37 PM rue_shop3: it was ungoogleable
10:37 PM Tom_L: shading with edges
10:38 PM Tom_L: shading with material but i didn't bother to define the material
10:38 PM Tom_L: so that option looks the same as what you see
10:39 PM robotustra: it's not for free
10:39 PM Tom_L: it's easier to work on the assembly with 'shading with edges' on
10:39 PM robotustra: looks like solidworks
10:39 PM Tom_L: same company
10:40 PM Tom_L: it's $$$$
10:40 PM Tom_L: sw is $$$
10:40 PM robotustra: I would not use SW even for free
10:40 PM robotustra: it's too heavy
10:40 PM robotustra: and slow
10:41 PM robotustra: and not parametric to the extent I would like to have
10:44 PM robotustra: fortunately there are russian hackers and russian cads :)
10:46 PM robotustra: https://imgur.com/wpG5Qjn
10:46 PM Tom_L: nice
10:46 PM Jak_o_Shadows: neat
10:47 PM Jak_o_Shadows: robotustra, you were doing the stero vision weren't you? Years ago?
10:49 PM rue_shop3: so, angle grinders motor runs at 41000 rpm...
10:49 PM robotustra: Jak_o_Shadows, I do
10:49 PM robotustra: but I'm workng on software patr for now
10:50 PM Tom_L: rue_shop3, i think this should be sturdier than the sherline
10:51 PM robotustra: rue_shop3, I think you don't need so high rpms
10:51 PM robotustra: I usually mill at 7200
10:51 PM robotustra: but can run at 2400
10:51 PM robotustra: but can run at 24000
10:51 PM robotustra: at 24000 - aluminum melts
10:52 PM Tom_L: not if you move fast enough and have good coolant
10:52 PM robotustra: and stuck in flutes of the mill
10:52 PM robotustra: no coolant of cause at 7200
10:52 PM Tom_L: no reason to go that fast though
10:52 PM robotustra: yes, the surface is prette clean
10:54 PM robotustra: https://ic.pics.livejournal.com/maholet/24765393/13447/13447_600.jpg
10:54 PM Jak_o_Shadows: aye, the software part was always gonna be tricksy
10:55 PM rue_shop3: I have a grinder head with a burned out motor
10:55 PM rue_shop3: its 3.75:1
10:55 PM robotustra: it would not be so hard, but I decided to write my own interpreter
10:55 PM rue_shop3: so, if I want to run it at the origional speed, I need a 40k motor
10:55 PM robotustra: rue_shop3, what for?
10:56 PM rue_shop3: I need a cutter jig
10:56 PM rue_shop3: for a special pipe slot
10:56 PM Tom_L: 9 x 24 big enough for a table?
10:56 PM rue_shop3: :)
10:56 PM rue_shop3: will it tip the works over?
10:56 PM Tom_L: we'll see
10:56 PM Tom_L: no not likely
10:57 PM robotustra: Jak_o_Shadows, why are you curious about stereo vision?
10:57 PM Jak_o_Shadows: nah, I just remember the mechanical side of it being cool
10:58 PM robotustra: yeah, and it's still works
10:58 PM robotustra: now I'm thinking about hands
10:59 PM robotustra: want to remake it in metal
10:59 PM robotustra: don't like printed plastic.
11:00 PM robotustra: https://imgur.com/Rkbuxti this guy goes to museum
11:01 PM Jak_o_Shadows: well dang, that's cooll as well
11:03 PM rue_shop3: robotustra, that looks properly done, wheres it from?
11:04 PM rue_shop3: the best I found is called "intel hand" and there is almost no information on it
11:04 PM robotustra: it's my own design
11:04 PM rue_shop3: oo!
11:04 PM rue_shop3: are any axies missing?
11:05 PM Jak_o_Shadows: I like the wrist
11:05 PM Jak_o_Shadows: but it seems like it may be underactuated?
11:05 PM robotustra: no, all axii are present
11:05 PM rue_shop3: robotustra, now many tendons for the last two three finger joints?
11:06 PM rue_shop3: (three)
11:06 PM robotustra: up to 3 bending and 3 undending, but I can combine them
11:07 PM robotustra: I want to make it working from 15 motors only
11:07 PM rue_shop3: neat, have a bigger photo gallery for it?
11:07 PM robotustra: it's about 24 DOF
11:07 PM rue_shop3: :) drop the pinkey
11:07 PM robotustra: no, I don't do much pics on not finished projects
11:08 PM rue_shop3: hmm, I'd like a set of images on it
11:08 PM rue_shop3: I'm pondering some things with the mecha hand
11:08 PM rue_shop3: need ideas
11:08 PM Jak_o_Shadows: Is it all separate? Or are you letting the plastic flex to dot he joints?
11:08 PM robotustra: http://i.imgur.com/c201ilj.png
11:08 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/sparrow1/p1080426.jpg
11:08 PM rue_shop3: :)
11:08 PM robotustra: it's all separate pices
11:08 PM robotustra: pieces

11:10 PM robotustra: I want to make human sized palm
11:10 PM Jak_o_Shadows: looks good
11:10 PM rue_shop3: I only did that many digits cause the actuator count goes insane with more
11:12 PM rue_shop3: I think the whole mecha is 47 axies
11:12 PM rue_shop3: thats what I should be working on, my force feedback stuff
11:13 PM robotustra: what is the size of your mecha?
11:14 PM robotustra: I go to sleep good night
11:14 PM Jak_o_Shadows: I need to get PWM working on the stm's Then a teensy little state-machine like thing, then DMA to PWM
11:14 PM Jak_o_Shadows: night
11:17 PM rue_shop3: do
11:18 PM rue_shop3: so
11:18 PM rue_shop3: you dont want to use my example?
11:18 PM Jak_o_Shadows: Have you gotten DMA->PWM? This is for dimming a LED in a pattern.
11:18 PM Jak_o_Shadows: For just normal PWM, I think I have your example, was gonna look at it
11:18 PM rue_shop3: no, got the pwm tho
11:18 PM rue_shop3: hmm
11:19 PM rue_shop3: cant remember now
11:31 PM rue_shop3: what I need is a WAREHOUSE for the projects I'm NOT working RIGHT NOW
11:33 PM evilroot: o.O
11:34 PM evilroot: Interesting stuff
11:34 PM evilroot: But horribly impractical
11:34 PM rue_shop3: more I need a long term plan for projects that are done
11:35 PM * evilroot has a warehouse
11:35 PM evilroot: And its full of projects that aren't done, heh
11:35 PM evilroot: And office space for ones that are
11:35 PM rue_shop3: and I have one large hexapod and one large robot arm too many for one TABLE
11:35 PM * evilroot has industrial Cartesian robots
11:36 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/robot_family2.jpg
11:36 PM rue_shop3: see the hex on the left?
11:36 PM evilroot: Its made out of bent steel rods o.O
11:36 PM rue_shop3: by all means, reffer to the ENLARGED disability cart for a size red
11:36 PM rue_shop3: ref
11:37 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/arm5/p1030984.jpg
11:37 PM evilroot: Is that a VHS camcorder??
11:37 PM rue_shop3: ref the hex on the left again
11:37 PM rue_shop3: for the size of the ROBOT ARM
11:37 PM rue_shop3: *sigh*
11:37 PM evilroot: What part of the world are you in?
11:38 PM rue_shop3: canada
11:38 PM evilroot: That stuff is ancient
11:38 PM rue_shop3: the west side not the stupid side
11:38 PM rue_shop3: I'm glad you can afford and have availability of new stuff
11:39 PM evilroot: I don't
11:39 PM evilroot: But I tend to stay in the last two decades
11:40 PM evilroot: With the exception of my bots, but they were insane to start with
11:41 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/arm5/p1030899.jpg
11:41 PM rue_shop3: better image...
11:41 PM evilroot: Very small image
11:41 PM rue_shop3: free webspace, I dont put up images larger than needed
11:42 PM evilroot: This isn't the 90's
11:42 PM rue_shop3: free
11:42 PM evilroot: You can host images of any size for free . . .
11:42 PM rue_shop3: if your willing to jump thru enough hoops and redo your site every 4 years
11:42 PM rue_shop3: im not
11:43 PM evilroot: Or just use Google
11:43 PM evilroot: Are those linear actuators from old medical beds?
11:43 PM rue_shop3: yup
11:43 PM rue_shop3: dc
11:43 PM evilroot: I recognize them from waaaay back
11:43 PM rue_shop3: unfortunatly using the relay controllers
11:44 PM rue_shop3: like I said, I'm glad you have availabelility and finances for newer stuff
11:44 PM rue_shop3: I'm sure the dc motors they make now are WAY better than those ones
11:45 PM evilroot: How old are you?
11:45 PM rue_shop3: about 160
11:46 PM evilroot: I'm liable to believe it
11:46 PM rue_shop3: I'm going for 8000
11:46 PM rue_shop3: +- 2000
11:46 PM evilroot: Also for reference Apache 2.2 is WAAAY out of date
11:47 PM evilroot: http://httpd.apache.org/docs/current/upgrading.html
11:47 PM rue_shop3: yea, someone can totally man-in-the-middle my insecure site and show you content thats not mine
11:48 PM evilroot: Also does that "arm" actually move?
11:48 PM rue_shop3: and I wont even know its not you instead of someone else
11:48 PM rue_shop3: yea
11:48 PM rue_shop3: potentiometer feedback
11:48 PM evilroot: You're a troll, right?
11:48 PM rue_shop3: I think the kids programmed it with 6 position storage locations
11:48 PM rue_shop3: no, I'm really real
11:49 PM rue_shop3: did you take a look at the other robots?
11:49 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/
11:49 PM evilroot: Yes, and they're absurd
11:49 PM rue_shop3: its a directory, you click on the text
11:50 PM evilroot: I can see them moving. Maybe. If you get lucky
11:50 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/nothingbot/nothing_bot.html
11:50 PM evilroot: But never actually doing anthing
11:50 PM rue_shop3: it moves fine
11:50 PM rue_shop3: it can crush cans great, 300kg grip
11:51 PM evilroot: But can it stop Kim Jong Un?
11:51 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Table_Assembly.jpg
11:51 PM rue_shop3: I suppose if I were inspired I could make a video of it doing a motion cycle
11:51 PM Tom_L: needs a longe screw
11:51 PM Tom_L: but i didn't have one handy
11:52 PM rue_shop3: oooh I see
11:52 PM Tom_L: needs a little work
11:52 PM rue_shop3: it might fit togethor great, but, it might be impossable to assembly
11:52 PM rue_shop3: assemble
11:52 PM rue_shop3: I think I need food
11:52 PM Tom_L: i'm looking at that as i go
11:54 PM evilroot: Tom_L: you keep posting stuff that looks almost exactly like my bots, heh
11:54 PM Tom_L: sry
11:54 PM Tom_L: :)
11:54 PM rue_shop3: evilroot, so, show me what you have made for $20, I want to see what your amazing resources do
11:54 PM evilroot: https://images.craigslist.org/00K0K_hhj6sJhnL4x_1200x900.jpg
11:55 PM Tom_L: yeah i saw that one
11:55 PM evilroot: rue_shop3: let me dig up something really old
11:55 PM rue_shop3: I'll figure out some supper while you do that
11:55 PM Tom_L: i've had enough for one day
11:56 PM evilroot: https://drive.google.com/file/d/0B5fQTi1W868OdUhqcDVFRTFIQzQ/view?usp=sharing
