#garfield Calendar
12:07 AM katsmeow: gnites
12:10 AM zhanx: i wonder if rue was buried by stuff looking for stuff
12:16 AM rue_: I found some stuff
12:16 AM rue_: quite valuable, the ring bearing design
12:17 AM zhanx: nice
12:17 AM rue_: which explains some things about why I'm doing it like I am
12:17 AM rue_: but no ring size diagrams
12:19 AM zhanx: wife told me today, build a shed/garage something
12:19 AM zhanx: to get my toys out of the house
12:20 AM rue_: hah
12:20 AM zhanx: 20x40 "shed"
12:21 AM rue_: 4 years of notes
12:21 AM zhanx: once i get proper work space it will be nice
12:22 AM zhanx: my workspace is my closet right now till it warms up
12:22 AM zhanx: then the back porch the wife stuffed with crap
12:23 AM zhanx: ok kid is out
12:24 AM zhanx: frame time
12:24 AM zhanx: school me
12:37 AM rue_: I dont know where your at right now
12:41 AM zhanx: stopped for the night
12:46 AM rue_: hah, I just found the tinyest footnote saying the inner ring is 8'
12:46 AM rue_: and confirming that the distace between the rings is 3"
12:53 AM zhanx: not going to deform the washers
12:53 AM zhanx: gonna run them on th a drill to sand them
12:54 AM rue_: did your kit have things for the bearings?
12:54 AM rue_: there would be 3
12:54 AM zhanx: no
12:54 AM rue_: k
12:54 AM zhanx: well the things the snap into yes
12:54 AM rue_: yea
12:55 AM rue_: do those work?
12:55 AM zhanx: washers are wrong
12:55 AM rue_: better than the fender washers
12:55 AM zhanx: and good
12:55 AM rue_: the ones I had snapped when I tried the bearings in them
12:55 AM rue_: so if your going to try I suggest warming them up
12:55 AM zhanx: issue is parts printed are not round
12:56 AM zhanx: i used my fingers
12:56 AM zhanx: they fit
12:56 AM rue_: as long as the spring is on the return side, not the motor drive side, they dont ahve to be round
12:57 AM rue_: the segment from the motor drive to the table should be stable, the rest is a chased takeup
12:57 AM zhanx: k
12:57 AM rue_: you saw I used a short belt and took the rest up with thin trimmer line?
12:57 AM rue_: and fishing line for the X
12:57 AM zhanx: thought that was fishing line for all of it
12:58 AM rue_: there is toothed belt from the motor drive to the table, and the bit of the belt that dosn't drive is replced with line and a takeup spring
12:58 AM zhanx: oh get this
12:58 AM rue_: http://ruemohr.org/~ircjunk/projects/reprap3/p1090799.jpg
12:58 AM zhanx: i can pick up a lathe for free
12:59 AM rue_: http://ruemohr.org/~ircjunk/projects/reprap3/p1090797.jpg
12:59 AM rue_: ... then you should do that
12:59 AM zhanx: i am\
12:59 AM rue_: ^^ that coupler, was just me having fun
12:59 AM zhanx: also those connections i don't like
01:00 AM zhanx: wife wants me to 3d laser scan shit
01:01 AM rue_: http://ruemohr.org/~ircjunk/projects/reprap3/p1090917.jpg
01:01 AM zhanx: upgrade
01:01 AM rue_: so, the belt goes from the carriage, around the motor, to the line, that then goes over the pulley and back to the carriage
01:02 AM rue_: http://ruemohr.org/~ircjunk/projects/reprap3/p1090920.jpg
01:02 AM rue_: you can kinda see it there in the background
01:02 AM rue_: the blue line is trimmer line
01:02 AM zhanx: i see what you are doing
01:03 AM rue_: http://ruemohr.org/~ircjunk/projects/reprap3/p1100006.jpg
01:03 AM rue_: furry junction in background
01:03 AM rue_: di that loop-to-loop with crimps
01:03 AM rue_: yea
01:04 AM zhanx: movement is cable rest line
01:04 AM zhanx: that is easy and nice
01:04 AM rue_: /translated/ yes
01:04 AM rue_: it ditches the need for tonnes of synchrobelt
01:04 AM zhanx: yep
01:05 AM zhanx: missing a pin tho
01:05 AM rue_: ... pin?
01:05 AM zhanx: to hold
01:05 AM zhanx: the hold
01:05 AM zhanx: but you are geared
01:06 AM rue_: the gearbox is transparent, it presents as a nema17 with a 5mm shaft
01:06 AM rue_: i used crazy glue to bind it to the shaft
01:07 AM zhanx: k
01:07 AM rue_: my red locktight dosn't seem to set
01:07 AM rue_: ... ever
01:07 AM zhanx: needs heat
01:07 AM rue_: OH!
01:07 AM rue_: how much!?
01:07 AM zhanx: ever read the label?
01:07 AM rue_: ...no
01:07 AM rue_: ya just goo it in and crank it tight
01:07 AM rue_: :)
01:07 AM zhanx: what um 200c?
01:08 AM rue_: hmm
01:08 AM zhanx: i know its 400 f
01:09 AM rue_: maybe its just me, but all these drawings from davinci seem to be mirrored?
01:10 AM zhanx: you?
01:13 AM rue_: oooh
01:13 AM rue_: davinvi you sneaky...
01:14 AM zhanx: scan them
01:14 AM zhanx: they are off
01:14 AM zhanx: by the moons
01:15 AM rue_: he told me what MY dimentions are...
01:16 AM rue_: and the answer is that the inner ring needs to be...
01:16 AM rue_: a min. of...
01:16 AM zhanx: gravity
01:17 AM rue_: 2036mm
01:17 AM rue_: 6.7 feet
01:17 AM rue_: so, technically 7 feet would do it
01:18 AM zhanx: 3.14 by what at 14,37
01:19 AM rue_: ?
01:19 AM rue_: if I only need 7' I wonder if I should do 8
01:19 AM rue_: might be toooo verkill
01:20 AM zhanx: pie x air pressure
01:20 AM rue_: but I dont knwo if I can take that pipe down to 7
01:20 AM rue_: not 2*pi*air_pressure?
01:21 AM zhanx: no its local
01:21 AM rue_: ok, here is what I'll do
01:22 AM rue_: I'll go to 7.5 feet
01:22 AM rue_: the 6" that saves me will be amazing
01:22 AM zhanx: why
01:22 AM zhanx: mass is not that much
01:23 AM rue_: this thing is already too huge
01:26 AM zhanx: wrong
01:26 AM rue_: er, yea
01:26 AM zhanx: mass location
01:26 AM rue_: this is for me, not 7'6" people who come to borrow it
01:26 AM rue_: oh, COM
01:26 AM zhanx: still the same
01:26 AM rue_: ... where is COM for a human
01:26 AM zhanx: com is 6'0
01:26 AM rue_: just under rib cage I think
01:26 AM zhanx: oh center of mass
01:26 AM zhanx: no
01:26 AM zhanx: hips
01:26 AM zhanx: well on me
01:26 AM rue_: hmm
01:26 AM zhanx: i am 280
01:26 AM zhanx: my COM is 2" above hips
01:26 AM zhanx: but i am not normal
01:26 AM zhanx: but your rig is not for fat people
01:26 AM rue_: ah, wait, invalid point, system will have dynamic counterweights
01:26 AM rue_: forgot about that
01:27 AM zhanx: thinking of making a human tread mill
01:28 AM rue_: a belt made of humans strapped togethr and stretched around two rollers?
01:28 AM * rue_ shakes his head
01:28 AM zhanx: hamster wheel for non Canadianism
01:28 AM rue_: for the kids!
01:29 AM zhanx: 14 feet diameter
01:29 AM rue_: rings 1, 2, 3, and the stand
01:30 AM rue_: https://www.xtreme-events.de/wp-content/uploads/aerotrim-verleih.jpg
01:30 AM rue_: yes, 1, 2, 3 and the stand
01:35 AM rue_: ok
01:35 AM rue_: I have all ID and OD numbers for the rings
01:36 AM rue_: I need to work out default orientations next
01:38 AM rue_: wait a sec, soemthign dosn't add up
01:39 AM rue_: its true, I can only reach to a little over 7'
01:49 AM rue_: ok, I have the arch depth for a 1m segment for each ring
01:50 AM rue_: hahah, the ring design is in a file under the bender design
01:55 AM rue_: eeek, old design had rings spaced 11" apart
02:03 AM rue_: thats a lot of thinking
02:03 AM rue_: I need a image with a sine wave, white on top, black on bottom
02:19 PM zhanx: rue_: you around?
02:30 PM zhanx: rue_: here is my progress report https://imgur.com/a/4EylxL1
02:30 PM rue_: nice
02:31 PM zhanx: to get the rest of the rods I tore apart these the fun way https://imgur.com/a/C85NVK2 but now i have a bunch of 10mm rods and short 2 8mm rods for the x axis
02:31 PM rue_: top of the Z rods, I had to turn the retainers around backwards to hold the rods
02:32 PM rue_: :)
02:32 PM zhanx: nothing beats opening junk printers with a hammer
02:32 PM rue_: screwless assembly be damned
02:33 PM rue_: I dont see any warnings
02:33 PM zhanx: now the problem i got
02:34 PM zhanx: I cant find my motor box
02:34 PM rue_: aha, there is one, you have two nuts betweeen the Y motor holder and the pulley, I think, for most motor shafts, you need to keep it down to 1
02:34 PM zhanx: bonus was i got another nema 17 today
02:34 PM rue_: hah
02:35 PM zhanx: rue that is just temp for now, i need to fix the washers on it
02:35 PM rue_: k
02:36 PM zhanx: rue i had a box with steppers i was saving for this project
02:36 PM zhanx: only found one motor i know was in that box
02:37 PM zhanx: which i forgot to ask you about
02:38 PM rue_: gtg 1hr or so
02:39 PM zhanx: ok uploading them now from the camera
02:39 PM zhanx: i think you will like this score
02:42 PM zhanx: https://imgur.com/a/iRdWeQA
07:02 PM zhanx: rue_: ping me when you get back on
07:40 PM zhanx: dont mind me, just jigged up and reduced the washers for the bearings and now make a jig to concave them
07:41 PM Tom_L: concave washers?
07:41 PM Tom_L: for what?
07:42 PM zhanx: bearing pressure without binding them
07:43 PM zhanx: i am trying to fix a couple of the i2 prusa's issues while i build it
07:43 PM zhanx: Tom_L: i am this far now https://i.imgur.com/SAf88yK.jpg
07:43 PM Tom_L: random steppers or did you order some?
07:43 PM zhanx: randoms
07:44 PM zhanx: still looking for my box of them, i found 2 so far wife thinks she tossed it on me
07:44 PM Tom_L: startin to take shape
07:44 PM Tom_L: i don't have any nema17 that i know of
07:45 PM Tom_L: got a few nema23
07:45 PM zhanx: i have 11 i think if i can find the box
07:45 PM Tom_L: single, double and triple stack
07:45 PM Tom_L: last ones i got were STRONG
07:45 PM zhanx: may have to order a matched pair for the z axis
07:46 PM Tom_L: ahh yeah, z takes 2
07:46 PM Tom_L: wonder why they didn't belt that and use one
07:47 PM zhanx: i don't know
07:47 PM Tom_L: last ones i got were 570 in oz
07:47 PM Tom_L: for the new mill
07:48 PM zhanx: large
07:48 PM Tom_L: not planning to stall it
07:49 PM zhanx: ever
07:49 PM Tom_L: i'm running them at 2.5A right now but could bump it up to 5
07:53 PM zhanx: my psu is 90a 12v
07:53 PM zhanx: its for the cnc i am gonna make later but using it for the 3d printer for now
07:58 PM Tom_L: that's kinda what i did with my sherline
07:58 PM Tom_L: built the control for this new mill in mind
07:58 PM Tom_L: you really want more than 12v for a mill though
07:58 PM zhanx: true
07:59 PM zhanx: 48v would be nice
07:59 PM Tom_L: that's what i have
07:59 PM Tom_L: got the transformers surplus
07:59 PM zhanx: nice
07:59 PM Tom_L: probably could use one but they had 3 so i parallel'd em
07:59 PM Tom_L: 18A approx
07:59 PM zhanx: after this 3d printer is done, working and 3d scanner
08:00 PM Tom_L: bbiab
08:00 PM zhanx: then back to the cnc via lost casting
09:00 PM rue_: you can use the 3d to make patterns for casting
09:00 PM rue_: if I can figure it out, you can make a wax printer
09:01 PM zhanx: how about i do it first
09:03 PM rue_: yep
09:03 PM rue_: wait
09:03 PM rue_: no, wax printer is mine!
09:03 PM zhanx: no
09:03 PM rue_: I'm not going to race a crippled person, you dont have a printer yet
09:04 PM zhanx: yet you see the pics?
09:04 PM rue_: hu?
09:04 PM zhanx: i turned the washers on sand paper
09:05 PM zhanx: tomorrow when kids are up i am concaving them
09:05 PM zhanx: i am at 85%
09:05 PM rue_: new pics?
09:05 PM zhanx: https://imgur.com/a/ByfAAg3
09:05 PM zhanx: last one i took
09:05 PM zhanx: https://imgur.com/a/jn1ak8b
09:06 PM rue_: k, looking good
09:06 PM zhanx: progress is good
09:06 PM zhanx: found all my limit switchs also
09:06 PM rue_: nic
09:07 PM zhanx: i ordered pla tonight
09:07 PM rue_: amazon?
09:07 PM rue_: amazon is good
09:07 PM zhanx: ebay
09:07 PM zhanx: cheaper
09:07 PM rue_: rlly?
09:07 PM zhanx: yep
09:07 PM rue_: ~$35 for _1_ kg?
09:07 PM rue_: have to be carefull, lots of people sell 1/2kg rolls
09:07 PM zhanx: 12 dollars for .5
09:08 PM rue_: that not much of a savings, maybe $3
09:08 PM zhanx: free shipping
09:08 PM rue_: yea so is amazon
09:08 PM zhanx: its a start
09:08 PM rue_: they threaten that standard shipping will take forever, but its the same
09:08 PM zhanx: nothing more
09:08 PM rue_: yea, you can do a LOT with .5kg
09:08 PM zhanx: upgrades
09:09 PM zhanx: i hope
09:09 PM rue_: yup
09:09 PM rue_: totally
09:09 PM rue_: I can feed you parts
09:09 PM rue_: we will get it going first
09:09 PM zhanx: ok
09:09 PM zhanx: i am missing my parts box for nema's
09:10 PM zhanx: wife thinks she tossed it
09:10 PM rue_: for the first few weeks, regularily check bolts and connectors (esp for heat)
09:10 PM rue_: oh no, thats worth about $55
09:10 PM rue_: no wait, they want about $25ea for motors now
09:10 PM rue_: so more like 125
09:10 PM zhanx: yea it sucks
09:11 PM rue_: well, start bring home large copiers to compansate for what the threw out
09:11 PM zhanx: i had 2 printers worth saved up
09:11 PM rue_: remember I said project box?
09:11 PM rue_: maybe a label would ahve been good
09:11 PM zhanx: it was labeled
09:11 PM rue_: ugh
09:11 PM Tom_L: what's up with the bender?
09:11 PM zhanx: DO NOT THROW OUT\
09:11 PM Tom_L: dianose it yet?
09:12 PM Tom_L: diagnose*
09:12 PM rue_: no, I'll tear it apart later
09:12 PM zhanx: bender is shock lash
09:12 PM rue_: I got 2 more peices bent, but the roller and the sprocket are pulling part from each other somehow, the sprocket runs eccentric under load
09:12 PM zhanx: oh rue_ made a jig to square up the printer to 1mm
09:12 PM rue_: which SHOULD be impossable cause the pin its running on is a perfect fit
09:13 PM Tom_L: too much pressure bending?
09:13 PM rue_: zhanx, with a basic level you can get lots closer than that
09:13 PM rue_: not sure
09:13 PM rue_: its a lot, I'v stalled that motor a few times
09:13 PM rue_: its a cruel motor
09:13 PM zhanx: well let me get it close tomorrow and we do that then
09:13 PM rue_: with a brutal grearbox
09:14 PM rue_: zhanx, you need motors...
09:14 PM zhanx: yes i do
09:14 PM Tom_L: you found the weak spot
09:14 PM zhanx: not happy about not having them
09:14 PM rue_: Tom_L, like I say, there is no way that sprocket should be able to run eccentric
09:15 PM Tom_L: i had to rewire my spindle motor today, the reverse relays were causing it to stop abruptly due to back emf
09:15 PM rue_: just make sure the current parts dont get thrown out while you collect the mtoors
09:15 PM Tom_L: so it just does fwd now
09:15 PM rue_: hmmm
09:15 PM zhanx: wife said just buy them, again not happy
09:15 PM Tom_L: but i wasn't using reverse anyway, just to test the rigid tapping
09:15 PM rue_: zhanx, thats over $100 into the project tho
09:15 PM zhanx: yep
09:16 PM zhanx: too much
09:16 PM rue_: large multifunction copiers
09:16 PM rue_: the document feeders are rich in them
09:16 PM zhanx: yep tuesday working on one
09:16 PM rue_: oh z
09:16 PM Tom_L: rue_, the 3 axis video... that was long standing oversight on my part in the cad program...
09:16 PM rue_: the lower middle bar, put it UNDER (if you can now)
09:16 PM Tom_L: was a feel good moment when i found it..
09:17 PM zhanx: can't bars are too short
09:17 PM zhanx: have to live with it
09:17 PM * rue_ produces a thumping sound with his head and desk
09:17 PM * Tom_L notices one is hollow
09:17 PM rue_: the belt may rub on it
09:17 PM zhanx: nope
09:18 PM zhanx: clears it not by a lot
09:18 PM rue_: from the back to the bottom of the motor
09:18 PM rue_: zhanx, you cant just buy the motors
09:18 PM zhanx: i won't
09:18 PM rue_: you need the synchro pulliess and the belt
09:18 PM zhanx: i got belts
09:18 PM rue_: so, scanners and printers are best
09:18 PM zhanx: from the printers
09:18 PM rue_: yea
09:18 PM zhanx: i got 9 now
09:19 PM rue_: you want 2 raw matched motors for z
09:19 PM zhanx: Tom_L: did you miss the me using a hammer on printers and nothing else to get parts
09:19 PM rue_: and 2 motors with pullies on them for x y
09:19 PM zhanx: i might have to order those
09:19 PM zhanx: the pullies i have to drill now
09:20 PM Tom_L: must have missed that
09:20 PM rue_: the problem is that now that you dont ahve the mtoors, your in risk of other things dissapearing
09:21 PM zhanx: to get the rest of the rods I tore apart these the fun way https://imgur.com/a/C85NVK2 but now i have a bunch of 10mm rods and short 2 8mm rods for the x axis
09:21 PM rue_: zhanx, did we flash the firmware on the arduino?
09:21 PM zhanx: we did
09:21 PM rue_: ok
09:21 PM zhanx: Tom_L: that link
09:21 PM rue_: did we set you up with librecad, openscad, slic3r and pronterface?
09:21 PM zhanx: yep
09:22 PM zhanx: software side is done till testing
09:22 PM rue_: go door-door and see if anyone has a printer they need to get rid of
09:22 PM rue_: maybe you can find them tonight
09:22 PM rue_: 8-|
09:22 PM zhanx: even better mother in law posted on face book
09:23 PM zhanx: i need 2 more 8mm bars to finish it
09:23 PM rue_: oh, cheap motors online are about $11 ea, those will prolly be pretty sad ones tho
09:23 PM Tom_L: awesome tool a hammer can be..
09:23 PM rue_: zhanx, 5/16 rod is only
09:23 PM zhanx: a hammer in my hands
09:24 PM useless is now known as katsmeow
09:24 PM zhanx: rue i got 8mmm bearing
09:24 PM zhanx: gonna match the rods
09:24 PM rue_: zhanx, 5/16 rod is only 0.0625mm out
09:24 PM katsmeow: hmm, 1/2 second canbe along time in mirc coding
09:24 PM rue_: 7.9375mm
09:24 PM zhanx: evening kat
09:24 PM rue_: hi kat
09:25 PM zhanx: rue_: its not straight if i buy it
09:25 PM katsmeow: .0625 is as think as a pcb
09:25 PM rue_: mm
09:25 PM rue_: 2.4 thou
09:25 PM zhanx: rue_: i started this printer build a year ago, i can wait a few weeks
09:26 PM * rue_ waits to see if anyone noticies his bad rounding
09:26 PM rue_: yes, this is true
09:26 PM rue_: screw the project box to the floor
09:26 PM katsmeow: mine eyes are going in circles atm anyhow, i seeing everything rounded
09:26 PM rue_: use large fender washers
09:26 PM zhanx: besides i spent a 1.42 for the extruder clamp
09:27 PM rue_: extruder clamp?
09:27 PM rue_: what IS that!?
09:27 PM zhanx: to hold the j head in
09:27 PM zhanx: you linked it
09:27 PM * rue_ , thumping noise...
09:27 PM zhanx: i found a cheaper one
09:28 PM rue_: I showed ya a pic of one I made from a scrap peice of alum sheet...
09:28 PM zhanx: i dont have your workshop to make one
09:28 PM rue_: ...
09:28 PM * rue_ moans...
09:28 PM zhanx: hence why my wife said build one
09:28 PM rue_: man I remember when I got a drill press
09:28 PM zhanx: so i can make it not buy it
09:29 PM rue_: everything I did to that point was a hand drill
09:29 PM katsmeow: one building : greenhouse, house, garage, workshop
09:29 PM rue_: to date, all I need is a hand drill
09:29 PM Tom_L: i was probably 8 when i got my first drill press
09:29 PM rue_: everything else is just icing
09:29 PM zhanx: i hand a drill press
09:29 PM Tom_L: used buffalo antique
09:29 PM zhanx: no drill for it
09:29 PM Tom_L: worn out
09:29 PM zhanx: got a hand drill
09:29 PM Tom_L: but i wore it out some more
09:29 PM rue_: then wore it back in?
09:30 PM Tom_L: i can't remember what i did with it
09:30 PM zhanx: doing a cross between rue and kats washer ideas
09:30 PM Tom_L: but it's gone
09:30 PM katsmeow: zhanx, might be easier if tyou foot-power the drill press
09:30 PM rue_: mmm sewing press
09:30 PM zhanx: katsmeow: i dont want to kill it
09:30 PM * rue_ rocks treaddle
09:30 PM katsmeow: foot powered lathes been around forever
09:31 PM zhanx: katsmeow: i can break a bike chain going up hill with my feet
09:31 PM katsmeow: don't do dat
09:31 PM rue_: yea, it can lead to groin pain
09:33 PM zhanx: or a torn sprocket
09:33 PM katsmeow: broken drill bit
09:34 PM zhanx: rue_: wifes facebook 5 printers being dropped off tomorrow
09:34 PM zhanx: should take care of the rods i need
09:34 PM rue_: sweet
09:34 PM rue_: the occassional wide format is yummy
09:34 PM zhanx: dc motors, i got them in trump
09:35 PM zhanx: i killed the encoders with the hammer
09:35 PM rue_: talk to print shops, they have dead printers almost all the time
09:35 PM zhanx: i will
09:35 PM zhanx: plotters also
09:36 PM zhanx: the upgrade to 10mm rods, is fine, i have all the rods
09:36 PM katsmeow: dont make any parts pink or red
09:36 PM zhanx: i wont
09:37 PM rue_: zhanx, yes, but, not a lot of point, there isn't much load on them to affect the rods
09:37 PM rue_: I did my second machine with 10mm on the X
09:37 PM rue_: mostly cause its long
09:37 PM zhanx: k
09:37 PM zhanx: i got 9 10mm rods
09:37 PM katsmeow: rue, how did long 1/2 emt work out?
09:37 PM rue_: and hte print dosn't really weigh anything
09:37 PM zhanx: also got 7 6mm rods
09:38 PM rue_: *blink* 1/2" emt?
09:38 PM zhanx: so i cam make a mini printer
09:38 PM katsmeow: didn;t you make something on emt rails?
09:38 PM rue_: ah, the cnc I tore apart
09:39 PM rue_: it was ok, but the overall design didn't work out
09:39 PM katsmeow: trick to make the xy table hold more weight: put a ball roller under the table at the point the print head works at
09:39 PM rue_: there's almost no weight on the table
09:39 PM rue_: a standard print is like 2g
09:40 PM katsmeow: bearing mounts are only 2g ?
09:40 PM rue_: heavy one maybe 50g
09:40 PM katsmeow: k, nvm
09:41 PM * katsmeow was thinking of a printer doing a 3ft tall gargoyle in cement or something
09:41 PM rue_: its more of a problem to have the head snag and knock the stepper out
09:42 PM katsmeow: xhanx laser scaning one of the kid and printingit out lifesized
09:42 PM rue_: :)
09:43 PM zhanx: with a z
09:43 PM zhanx: :D
09:43 PM zhanx: that is possible
09:43 PM rue_: with PLA, making a print much more than about 15cm is trickey, the plastic shrinks so much it tears itself off the print bed
09:43 PM katsmeow: rue, have your Saturday kids rint out wearable halloween heads ?
09:43 PM rue_: just one right now, and its trickey
09:43 PM rue_: kids dont always focus well
09:44 PM katsmeow: maybe they need to be interestedi something that pertains only to themselves
09:45 PM rue_: its only worth it for me if I use them as slave labour :)
09:45 PM rue_: lets take a printer apart!!!!
09:45 PM rue_: lets build a 12' mecha!
09:45 PM rue_: lets assemble circuit boards!
09:45 PM rue_: lets make a 3d printer!
09:45 PM rue_: ...
09:45 PM katsmeow: yea........
09:46 PM rue_: I do want to teach them stuff
09:46 PM rue_: but it cant be the main goal anymore, all the kids that learned stuff left
09:46 PM zhanx: rue_: not my kids
09:46 PM katsmeow: they learned they were slaves?
09:47 PM zhanx: slaves only vote democrat rue is a canadian
09:47 PM rue_: no, I thought it would be good to make people that knew things like I do
09:47 PM rue_: so we could work togethor
09:47 PM rue_: and it didn't work out
09:48 PM rue_: so now if I teach them stuff by letting them help on my projects, atleast i come out at the end of the day with something for me
09:48 PM katsmeow: you are out of their age bracket, nothing works for them like it does for you
09:48 PM rue_: I know
09:49 PM rue_: but, I have the knack
09:49 PM rue_: you can tell if a kid has the knack, they are too busy to come to places like this and learn advanced stuff
09:50 PM katsmeow: o
09:51 PM katsmeow: has the knack, loose track
09:52 PM * katsmeow ponders a 14" tall half-rack to shelf mini-itx/-atx into these 20 yr old puter cases
09:53 PM zhanx: rue you use TPU or TPE flexible filament yet?
09:54 PM katsmeow: shelf up the hdds beside them
09:54 PM rue_: back in 97, I was going to build a 'round table' of about 16 286 motherbaords, on edge, in a circle, with a common ide drive
09:54 PM rue_: and a bus sharing system
09:54 PM rue_: zhanx, PLA filament...
09:55 PM katsmeow: why a circle? you like crays?
09:55 PM rue_: so no
09:55 PM rue_: keep the ide lines close to each other
09:55 PM rue_: I was gonna use a wait system
09:55 PM rue_: they would all use the same drive
09:56 PM katsmeow: yea,, the OS hiding the cache flushing wold have bitten you
09:56 PM rue_: I didn't know if dos checks if a sector is free before using it, or uses a cache
09:56 PM katsmeow: and, no way to tell a program another mobo just changed the file contents
09:57 PM zhanx: https://rigid.ink/blogs/news/172062855-what-is-the-difference-between-tpe-and-tpu-flexible-filament
09:57 PM rue_: I didn't go thru with it, mostly because POVRAY didn't get backported to 286
09:57 PM katsmeow: i has a copy of that, and the book too
09:58 PM rue_: http://ruemohr.org/~ircjunk/art/clipper.png
09:58 PM rue_: I did lots of povray stuff for a long time
09:59 PM katsmeow: when it took all nighyt to do 1/4 of a screen, i stopped
09:59 PM rue_: heh, I'd do crude resolution, then dial it up when I knew it was what I wanted and let it run for a day
10:00 PM rue_: I was also doing animations
10:00 PM rue_: that guy walks
10:00 PM rue_: you just move the body around, and the legs figure themselvs out
10:00 PM rue_: (in a more of less plausable way)
10:01 PM katsmeow: speakingof legs, did RiffRaff ever finish Foxy ?
10:01 PM rue_: I dont think so
10:01 PM katsmeow: o
10:01 PM rue_: she was in storage for quite a bit while he moved around
10:02 PM katsmeow: he left the cow pasture?
10:02 PM rue_: rifraf is one of those people who take on something new, master it, throw it all away and go start soemthing else
10:03 PM rue_: I got a trip to oz out of it!
10:04 PM katsmeow: did you wanna stay?
10:04 PM rue_: I got a washing mahcine valve today
10:04 PM rue_: the houses cost just as much there as here
10:04 PM zhanx: katsmeow i combined your impact socket with my grinding for the washers
10:05 PM katsmeow: yea,, hence i built mine
10:05 PM rue_: $200k for a little lot
10:05 PM katsmeow: rue, do like ma: boat!
10:05 PM rue_: now my lot is eval at over $500k
10:05 PM rue_: I 'own' it now
10:05 PM zhanx: with a punch the concave is more even
10:05 PM katsmeow: i cannot afford the taxes on $500k
10:06 PM zhanx: so thanks\
10:06 PM rue_: yea, I want my place to do its own taxes
10:06 PM zhanx: with the \
10:06 PM katsmeow: <curtsey>
10:07 PM zhanx: ruw i will get you pics tomorrow the washers act like locking ones
10:07 PM rue_: k

10:07 PM zhanx: with only 8 todo its do able
10:08 PM zhanx: no you tried and failed to find them
10:08 PM rue_: http://ruemohr.org/~ircjunk/projects/reprap3/p1090683.jpg

10:18 PM zhanx: rue if you need washing machine solinoids i got them
10:19 PM rue_: kat, we almost need a website pre-parser, that turns the crap-meta-garbage into html1
10:19 PM rue_: zhanx, yea, but I need 47? of them
10:19 PM katsmeow: heh

10:20 PM zhanx: they will be a trade
10:21 PM zhanx: my parts for your parts
10:21 PM zhanx: gifts

10:22 PM zhanx: but i have to pull them
10:23 PM rue_: I dont know how long this next week will be
10:23 PM rue_: it'll be hell
10:23 PM zhanx: i am booked all week also
10:23 PM rue_: I have a PANIC PANIC PANIC elevator/fire alarm job, and the hospital fire alarm inspection
10:24 PM rue_: I have more helpers than I did last year, so. mmm see...
10:24 PM zhanx: i got a pharmacy door to fix monday
10:24 PM rue_: automatic?
10:24 PM zhanx: nope
10:24 PM zhanx: old school
10:24 PM rue_: mmm
10:25 PM rue_: "its digital, operate with fingers"
10:25 PM * rue_ looks to kat
10:25 PM zhanx: even worse
10:25 PM zhanx: key card
10:25 PM rue_: oh HID reader?
10:25 PM katsmeow: oh, just fish the penny out of the card reader
10:25 PM zhanx: NFC
10:25 PM rue_: white and green are data, red and black power
10:26 PM rue_: winegart?
10:26 PM zhanx: no brand in the wo
10:26 PM rue_: is there a seperate controller box?
10:26 PM zhanx: yes
10:27 PM rue_: yea
10:27 PM rue_: prolly winegart
10:27 PM rue_: they use one of two freqs
10:27 PM rue_: (rf)
10:27 PM rue_: the reader just sends to the controller
10:27 PM zhanx: i will see it when i get there
10:27 PM rue_: if the reader dosn't beep, its most likley the problem
10:27 PM rue_: [ if what I think ]
10:27 PM zhanx: i got the knack also
10:28 PM zhanx: since that is what we are calling it
10:28 PM katsmeow: song about that
10:28 PM katsmeow: not use if The Knack sings it
10:28 PM katsmeow: sure
10:28 PM katsmeow: user-sure
10:28 PM rue_: the reader reads the card, beeps, flashes light, the controller compares serial number, maybe releases door *and turns on the light on the reader to indicate confirm*
10:29 PM rue_: which is not like one might expect
10:29 PM rue_: but point being, the reader should have life even if its just got power
10:29 PM rue_: I was gonna make controllers, cause even china wanted a mint for them
10:29 PM rue_: 2 door controlers are like $600 out here
10:29 PM rue_: which is insane
10:30 PM rue_: I managed to take a reader and make a controller that will use the first read card as its only accepted card
10:30 PM rue_: :)
10:30 PM rue_: (I know you got it )
10:31 PM rue_: hmm
10:31 PM rue_: 1 hour left to live
10:31 PM rue_: I need supper
10:31 PM rue_: and a plan
10:31 PM rue_: a few plans wouldn't hurt
10:32 PM katsmeow: i was just thinking of cookies, which i have none of
10:32 PM zhanx: ok washers as to size
10:32 PM rue_: go to www.google.com, lots of cookies from them
10:32 PM zhanx: now to punch them out
10:33 PM rue_: and I ahve to find a harness for the cage
10:33 PM zhanx: oh look i have a punch the perfect size
10:33 PM katsmeow: rue, use a cookie preloader, 1000 cookies full of nonsense to break any script that gets them from me
10:34 PM rue_: oh they like to scan cookies dont they
10:34 PM katsmeow: yeas
10:34 PM katsmeow: wtf would imgur and wikipedia need to set cookies?
10:34 PM rue_: mayeb thts what going on when 'nothing' is happening at 20% cpu
10:34 PM rue_: their scanning cookies
10:35 PM rue_: tracking, to follow ya thru the internets
10:35 PM katsmeow: err, i am online from a Toronto ip addy, good luck
10:35 PM rue_: they dont care about the quality of the data they collect, just volume
10:36 PM rue_: people dont pay for quality
10:36 PM rue_: I doubt any ad shop ever said "I'd pay just as much for *one* valid email address!
10:36 PM rue_: "
10:37 PM katsmeow: i think they get usernames, and throw all of them at each isp and mailhouse
10:37 PM rue_: I used davinci's work to size the control cage, I hope he was right
10:38 PM katsmeow: so they try katmeow@ every place that hosts mail
10:38 PM rue_: ok supper, I have to think
10:38 PM zhanx: ok punch failed
10:38 PM katsmeow: failed?
10:38 PM rue_: WHAT HAPPENED TO THE TABLE!!!!!
10:38 PM zhanx: flaring tool next
10:38 PM zhanx: it broke
10:38 PM katsmeow: too much dynamite in the hydraulic ram ?
10:39 PM zhanx: been working out more so i guess
10:39 PM zhanx: wife is gonna kill me
10:39 PM katsmeow: what "it" broke, exactly?
10:40 PM zhanx: ripped a chunk out of the table
10:40 PM katsmeow: not supposed to happen
10:40 PM * zhanx puts away the hammer
10:40 PM katsmeow: oh
10:40 PM katsmeow: defective targetting
10:42 PM zhanx: targetting was 100% spot on
10:42 PM zhanx: table was not
10:42 PM zhanx: or the hammer was too big
10:42 PM zhanx: not my fault i think
10:43 PM zhanx: granted i know its not real wood
10:43 PM katsmeow: have you considered pouring a concrete table?
10:44 PM zhanx: i need a steel one
10:44 PM zhanx: to be fair, i break shit
10:44 PM katsmeow: concrete is heavier
10:44 PM katsmeow: i cast one with pvc pipe in it, so i could bolt things down to it
10:45 PM zhanx: concrete and me 10 minutes of me with a hammer
10:45 PM katsmeow: ok, the bolt down a 1/2" plate steel
10:45 PM zhanx: that is what i was thinking or 3/4 just in case
10:46 PM katsmeow: i get a lot of mileage outa the 1/4" steel one i been using a yr now
10:46 PM zhanx: i missed today and broke a 2x6
10:47 PM Tom_L: just don't drive thru your house
10:48 PM zhanx: cant

10:50 PM rue_: and a table
10:50 PM zhanx: 23 years later will have dinner and my 3d printer frame will be straight
10:50 PM rue_: dont worry about straight now
10:50 PM rue_: there will be SO much adjusting, anything you do now just dosn't count

10:54 PM rue_: there were a whole bunch of barrels at the recycler, I was tempted
10:54 PM rue_: but I wasn't sure if I would still be net-positive if I took one
10:55 PM katsmeow: recycle milk jugs?
10:55 PM rue_: hdpe
10:55 PM zhanx: yep kat
10:55 PM katsmeow: i must have 50+ rinced-out milk jugs with no purpose

11:00 PM rue_: hmm
11:00 PM rue_: and pick them and keep the plant to make more
11:00 PM zhanx: no
11:00 PM katsmeow: don;t taotes need to be nested in something, even if not soil, because of the weight?
11:01 PM zhanx: 50/50
11:01 PM rue_: 3d pritned potato slings?
11:01 PM katsmeow: geotextile fabric?

11:06 PM Tom_L: i put alfalfa hay over mine
11:07 PM Tom_L: while growing anyway..
11:07 PM zhanx: ok back to sanding the washers
11:08 PM * katsmeow is trying to deside using the TDA7293 or 7294
11:10 PM * Tom_L goes horizontal for a spell
11:12 PM katsmeow: gnite Tom
11:19 PM katsmeow: i figure the cheaper one will do, power it from +50 and -5 , to swing a 42v psu from 0v to 42v
11:31 PM rue_: "you took my mouse, AND THEN LOST IT!? WTF!?"
11:31 PM rue_: Tom_L, I tried that this year
11:32 PM rue_: zhanx, so should I send you that stuff?
11:33 PM rue_: maybe I could send that the stuff in her pile too
11:33 PM rue_: if I can find it...
11:33 PM * rue_ gets sleepy
11:33 PM zhanx: yes
11:42 PM rue_shop4: I have come up with a krafty solution for super
11:42 PM katsmeow: i wonder that the energy source for the robots in Westworld tv series is
11:54 PM rue_shop4: zhanx, and the 'stabalizers' that go in corners of the printer, are not worth it 90% of the frame flex is cause of using threaded instead of solid rod
11:57 PM rue_shop4: I wonder if I'll ever find what I'm looking for on irc
11:58 PM katsmeow: i doubt it, it's fullof talking humans and non-talking bots
11:58 PM zhanx: hmmm
11:59 PM katsmeow: except when the humans do not talk too
11:59 PM rue_shop4: hmmm
