12:00 AM zhanx: it should make a good scan
12:03 AM rue_shop3: you should use that nut trick
12:03 AM rue_shop3: you will notice the grub screws tearing the prints apart
12:03 AM zhanx: no its for the scanner
12:03 AM rue_shop3: yea
12:03 AM rue_shop3: ditto
12:03 AM rue_shop3: I have an ABS gear here thats elliptical
12:03 AM zhanx: well its version 2 so we will go from there
12:03 AM rue_shop3: cause of the force from the grub screw
12:03 AM rue_shop3: you, want to print a new pinion for your extruder beofre that one breaks...
12:03 AM rue_shop3: cause if it breaks in a way you cant jurry-rig it...
12:03 AM zhanx: i plan on next week printing the rest of the printer parts
12:05 AM rue_shop3: I need like 150% motivation right now, I'm fighting as hard as I can
12:06 AM rue_shop1: I think its 75% solatary confinement
12:07 AM rue_shop1: I'm at home alone, go to work, work alone all day, go back home and rattle around alone in the house
12:07 AM rue_shop1: weekend, I have a few visitors, and otherwise rattle around myself
12:08 AM rue_shop1: that why I'm getting so good at holding a conversation with ya
12:08 AM rue_shop1: thanks, I'm sure it consumes no resources either
12:08 AM rue_shop1: well learn to make a proper neural network then
12:08 AM zhanx: happens to me too
12:08 AM zhanx: fuck i live on the side of mountain in a swamp
12:08 AM rue_shop1: it also doesn't help I got almost nobody to talk to things about
12:09 AM zhanx: oh!! on that note
12:09 AM rue_shop1: less irc, and 90% of the time I dont line up with anyone else
12:09 AM zhanx: the local hospital wants to hire me
12:09 AM rue_shop1: yoru already hired by everyone else
12:09 AM rue_shop1: and the mil.
12:10 AM zhanx: but i want steady pay
12:10 AM rue_shop3: thoguth you were working for a company now
12:11 AM zhanx: 25
12:11 AM zhanx: but work was zero this week
12:23 AM rue_mohr: hmm
12:23 AM rue_mohr: I got the impression it was full time?
12:23 AM rue_mohr: were they just gigs?
12:24 AM zhanx: gigs but full time ish
12:24 AM zhanx: lots of work in an area that had no one
12:24 AM zhanx: problem is i am fixing it all
12:24 AM rue_mohr: that just sounds like a recipie for disaster
12:24 AM rue_mohr: gaps and overlaps
12:24 AM zhanx: yep
12:25 AM rue_mohr: eamil says there are things in my mailbox
12:25 AM rue_mohr: !
12:26 AM rue_mohr: lets go C!
12:35 AM rue_mohr: 3 packages!
12:36 AM zhanx: rue printer is not overheating must have been the connector
12:37 AM rue_mohr: wtf, K thermocouple thing only goes to 400C!?!?!
12:37 AM rue_mohr: zhanx, taht why you want the graph, just a little spike will set it off
12:37 AM zhanx: watching
12:38 AM zhanx: now
12:38 AM zhanx: and print quality is higher slower
12:39 AM rue_mohr: to a limit, yea
12:39 AM zhanx: i can see that
12:40 AM zhanx: lets see last month shit prints, this month great printer but how to make them better, its a win
12:40 AM zhanx: after this slew drive is done the 5 dof arms are next for soldering
12:50 AM zhanx: officially mad at you
12:50 AM rue_mohr: ?
12:50 AM rue_mohr: I was right about?
12:50 AM rue_mohr: :S or was I wrong...
12:50 AM zhanx: no you forgot to tell me the 25th time on how to slow down
12:50 AM zhanx: :#
12:51 AM rue_mohr: its just a fact, your gonna do your own thing
12:51 AM rue_mohr: like the gearbox, I'm sure your working on modifying the design and its not even all made
12:51 AM zhanx: oh no i asked on this before, own it
12:52 AM rue_mohr: mhm
12:52 AM zhanx: nope waiting on that my focus is the 3d scanner
12:52 AM rue_mohr: how many times has it xy shifted a print casue the head snagged on a high-slope edge?
12:53 AM zhanx: a few for sure
12:53 AM zhanx: wait what was that small size printer you asked me about
12:54 AM rue_mohr: tiny
12:54 AM rue_mohr: like 10x10cm
12:54 AM rue_mohr: but super high resolution
12:54 AM zhanx: better than the .15mm i am getting?
12:54 AM rue_mohr: yes, way better
12:54 AM rue_mohr: in X and Y too
12:54 AM zhanx: i am in
12:55 AM rue_mohr: I was wondering if it'd crossed your mind along the same time as the machine big enough to print a house
12:55 AM zhanx: yes and no
12:55 AM zhanx: drones fed off printers
01:06 AM rue_mohr: hmm
01:10 AM zhanx: rue this print will work thanks
01:24 AM rue_mohr: well damn, this is my fault, the thermocouple temp controller I got is only good to 400c
01:25 AM rue_mohr: if I'd looked at the model details, I'da realized that
01:25 AM rue_mohr: opened it up, there is nothing simple I can do
01:25 AM zhanx: wrong one?
01:25 AM rue_mohr: its an 8051 controller, with a custom analog interface
01:25 AM rue_mohr: I wanted 1600c
01:25 AM rue_mohr: :/
01:25 AM rue_mohr: anyhow
01:25 AM rue_mohr: $18
01:26 AM zhanx: 18 is like 24 usd now
01:26 AM rue_mohr: $16 I suppose, if you count the K thermocouple and the SSR at $1ea
01:28 AM rue_mohr: oh wait, maybe its software configurable..
01:30 AM rue_mohr: hmm wonder if I should plug in it and push buttons
01:42 AM rue_mohr: oh, wait a min
01:42 AM rue_mohr: this is funny
01:42 AM zhanx: k
01:42 AM rue_mohr: the limit might only be imposed by the thermocouple that came with it
01:42 AM rue_mohr: aka, this thermocouple is type K, but isn't rated for more than 400c
01:43 AM rue_mohr: haha
01:44 AM rue_mohr: hahah
01:44 AM zhanx: ok at 1.250 mm layer height
01:44 AM rue_mohr: I think its true, halarious
01:44 AM zhanx: that is 6x .2
01:44 AM rue_mohr: you should be clear to go to full speed
01:44 AM zhanx: i can turn it up now?
01:44 AM rue_mohr: I think :)
01:44 AM zhanx: k
01:44 AM zhanx: 75% then
01:48 AM rue_mohr: so, I have a sensor comming that'd be rated for the whole 1300c
01:48 AM rue_mohr: hmm
01:48 AM zhanx: i will do a few layers and then go 100%
01:54 AM rue_shop1: I'm still waiting for a breakdown of this new printer
01:54 AM rue_shop1: nothing so far
01:55 AM rue_shop1: hour counters would be nice
02:06 AM rue_shop1: zhanx, the 2:1 has to be run-in when you finish it
02:06 AM rue_shop1: I leave it in the drillpress for a while
02:10 AM rue_shop1: not dialed in tight
02:10 AM rue_shop1: then adjust and lube as it ages on the machine
02:10 AM zhanx: k
02:13 AM rue_shop1: I have two versions of the gearbox
02:14 AM rue_shop1: the one I started you on is specifically for the Y
02:14 AM rue_shop1: the other is for X, but its face is a NEMA17
02:14 AM rue_shop1: so you can use it in place of any nema17 plate
02:15 AM rue_shop1: the Y version is a Y bracket literally mashed into the gearbox plate in openscad
07:39 AM Tom_L: what plastic requires 1300c?
10:34 AM rue_bed: no,for casting metal
12:15 PM rue_shop1: and I was seeing if I could put togethor a temp alarm for a glass kiln
02:15 PM rue_shop1: zhanx, if you take tooooooo long I'm gonna forget where I was, aside from time, what in the way of gettin those nuts ready?
04:13 PM Tom_L: you get too many more printers and the old ones will start acting out
04:25 PM rue_mohr: so many things to improve...
04:27 PM rue_shop1: I'm focusing on the new printer, and its doing great
04:34 PM Tom_L: are they all pretty much the same?
04:39 PM rue_shop1: basic same design, but I'v upgraded and changed all sorts of things among them
04:40 PM rue_shop1: I need to sit down for a while and backpropigate upgrades
04:40 PM rue_shop1: which will result in 4 spare steppers and 3 spare peices of threaded rod
04:49 PM Tom_L: all the steppers the same?
04:53 PM rue_mohr: no
04:54 PM rue_shop1: all 200ppr
04:56 PM Tom_L: does that make it hard to get them all the same?
04:56 PM Tom_L: or are they all nema17..
05:07 PM rue_shop1: the Z is worst, you need a pair
05:07 PM rue_shop1: thats what I 'm gonn fix tho
05:11 PM rue_shop1: the design is still using a few linear bearings I need to get rid of
05:11 PM rue_shop1: too
05:13 PM Tom_L: linear bearings don't work well?
05:35 PM rue_mohr: no
05:35 PM rue_mohr: hoiid things
05:35 PM rue_mohr: horrid things
05:37 PM Tom_L: what do you use instead?
05:37 PM rue_mohr: they are never the right tension on the rod
05:37 PM rue_mohr: always too loose or too tight
05:37 PM rue_mohr: so I use bearings on a "3 way" grab
05:38 PM rue_mohr: with 5 bearings grabing one bar as a reference, and two bearings grabbing the other as a steady
05:38 PM Tom_L: hmm
05:38 PM rue_mohr: unbindable
05:38 PM rue_mohr: aka why you dont put two lienar bearings in parallel
05:39 PM rue_mohr: even the slightest error will cause them to eat each other
05:39 PM rue_mohr: saw a great example in an old tape changer
05:40 PM rue_mohr: it'd eaten right thru a 6mmm bushing
05:41 PM Tom_L: how do the number ratings on welding glass go? is 8 darker or lighter than 10?
05:41 PM Tom_L: i fogot
05:41 PM Tom_L: forgot
05:41 PM rue_mohr: :S dunno
05:41 PM rue_mohr: iirc on the mask, higher is darker
05:41 PM Tom_L: i don't use em much anymore since i have the self darkening
05:42 PM rue_mohr: :) ok, I redesigned a part I dont even need, perfect...
05:42 PM Tom_L: may range from a #8 shade for low-amp applications up to a #13 shade for high-amp applications.
05:42 PM Tom_L: so 8 is lighter
05:42 PM Tom_L: that's what i thought
05:42 PM Tom_L: good pratice for ya
05:43 PM rue_mohr: I'm bothered by one of the parts I'm using becasue the desgin isn't symmetric
05:43 PM Tom_L: if i new about it i could cad one up pretty easy
05:43 PM rue_mohr: I needed a bunch more, but it turns out I'd already printed a whackload of them
05:44 PM rue_mohr: too simple a part
05:44 PM rue_mohr: its just an extruded profile with two cylinders knocked out of it
05:45 PM rue_mohr: hey, this is a good holiday project! I need a 30 min timer for my ricemaker
05:45 PM rue_mohr: how do I box that one up..
05:45 PM Tom_L: i got an extra day off i didn't figure on
05:45 PM rue_mohr: next work day is the 2nd for me
05:46 PM rue_mohr: are you working full or part time/retired?
05:46 PM Tom_L: naw i'll work between
05:46 PM Tom_L: full
05:46 PM Tom_L: i don't get to retire
05:46 PM rue_mohr: somehow I didn't think you worked full time
05:46 PM Tom_L: self employed
05:46 PM Tom_L: so if i want off i can but i don't
05:46 PM rue_mohr: nobody gets to retire,
05:47 PM Tom_L: not since the last administration ruined our country
05:47 PM rue_mohr: we have people 78 going back to work cause they cant live on the pension
05:47 PM Tom_L: exactly
05:47 PM rue_mohr: you know how slow a cashier thats 78 moves!????
05:48 PM rue_mohr: I need to work out how to make money with little/no effort
05:49 PM rue_mohr: some method of utilizing equipment/capital
05:49 PM Tom_L: that would be nice
05:50 PM rue_mohr: there are tonnes of people in the world who could make a fortune with the eequip that I have
05:50 PM rue_mohr: not me tho
05:50 PM Tom_L: could start selling crack like everyone else....
05:50 PM rue_mohr: I'm sitting here blinded by the light
05:50 PM Tom_L: good money in that
05:50 PM rue_mohr: pot went legal, I mgiht be able to sell starter plants
05:51 PM rue_mohr: to the nurseries?
05:51 PM rue_mohr: hmm
05:51 PM Tom_L: you need something nobody else has
05:51 PM Tom_L: bigger, better, smarter, whatever...
05:51 PM Tom_L: the programmers were fun for a while
05:53 PM rue_mohr: :) there is still a market for those ya know
05:53 PM rue_mohr: just not worth what it needs to be
05:54 PM Tom_L: i doubt the studio of today would even recognize it
05:54 PM Tom_L: if there even is one now
05:54 PM rue_mohr: if it had nativly been a 10 pin, I'd prolly have never set up anything else
05:54 PM Tom_L: i haven't kept up
05:54 PM rue_mohr: it does seem avr is on the downhill slope
05:55 PM Tom_L: every dog has his day
05:55 PM rue_mohr: esp when the stm32's come in aruduino form factor and are actually cheaper
05:55 PM Tom_L: seem harder to program
05:55 PM rue_mohr: but stm32 isn't organized like the avr stuff was
05:55 PM rue_mohr: the software base isn't right , its still where avr was about 2002
05:56 PM rue_mohr: remember trying to compile avr libc?
05:56 PM rue_mohr: and we had to start building custom scripts to do all the stupid stuff?
05:57 PM rue_mohr: well, the next redesign I need to do for the printers is a huge daunting one
05:57 PM Tom_L: which is?
05:57 PM rue_mohr: it can be widdled down to just big
05:57 PM rue_mohr: so, the ninnies who designed it, used two motors wired in parallel for the Z
05:58 PM rue_mohr: and they used leadscrews
05:58 PM rue_mohr: it should be a gear-reduced, belt driven axis
05:59 PM rue_mohr: the change means redesigning the top motor mounting plates, adding idlers to the bottom
05:59 PM rue_mohr: and building a geared motor mount for it all
05:59 PM rue_mohr: tho, I have some steppers with an insane reduction box in them
06:01 PM Tom_L: ok, the ice cream was a bad idea
06:02 PM Tom_L: now i'm sittin here shivering
06:02 PM * Tom_L goes to make tea
06:19 PM rue_shop3: hah, oo yea I screwed up the mirroring
