12:11 AM katsmeow: never before talked to someone with all their vehicle batteries dead, trying to convince them they need a batery charger
12:14 AM katsmeow: for over an hour
12:14 AM katsmeow: it's after midnite, my brain is fried and off, gnites
12:29 AM zhanx: rue_bed, ok my nozzle quit extruding
12:29 AM zhanx: motor is not hot
12:29 AM zhanx: think i got something in it
12:57 AM rue_bed: heh
12:58 AM rue_bed: run it up a bit hot and poke thestraightened end of a sufficiently sized spring in there, and give it crisco
12:58 AM rue_bed: atiny bit on the filament
12:58 AM rue_bed: as its printing
12:59 AM rue_bed: it shouldn'tplug up
01:00 AM rue_bed: sometimes they accidently mix some ABS into cheap pla
01:00 AM rue_bed: if so, you have to ramp the temp up and extrude a bit
01:00 AM rue_bed: try the spring first, maybe you managed to get some steel in there
09:27 AM rue_mohr: https://www.mikrocontroller.net/attachment/222819/cc1.png
06:21 PM zhanx: ok rue bed is .01 mm +- leveled now
09:30 PM ^kat^: <cough>
09:30 PM ^kat^: <cough> <cough>
09:30 PM ^kat^: <cough> <cough><cough> <cough> <cough> <cough> <cough> <cough> <cough> <cough>
09:31 PM ^kat^: <COFF> <COFF> <COFF> <COFF> <COFF> <COFF> <COFF> <COFF><COFF> <COFF> <COFF> <COFF>
09:31 PM ^kat^: ACKACKCOFF
09:32 PM * ^kat^ carries something outside
09:32 PM ^kat^ is now known as ^kat^-afk
09:37 PM rue_bed: hi
09:37 PM rue_bed: nothing but smoke outside over here kat
09:38 PM rue_bed: I think california and canada are burning down
09:38 PM zhanx: rue_bed, see my bed level now?
09:38 PM rue_bed: yes!
09:38 PM zhanx: better?
09:38 PM rue_bed: did you get Y fixed?
09:38 PM zhanx: i would say so
09:39 PM zhanx: i am printing a second set of parts now
09:44 PM ^kat^-afk is now known as ^kat^
09:45 PM ^kat^: rue, they are saying it's record-setting amounts of land burning
09:46 PM ^kat^: strange too, being they are locted next to the world's largest body or water, and have the best collection of plases they couldbe storing water all over Calif, Oregon, and Washington
09:46 PM * ^kat^ paws are sore
09:50 PM rue_mohr: zhanx, shoot me a pic of your whole machine so I can suggest parts
09:51 PM zhanx: k
09:52 PM zhanx: rue_mohr, keep in mind i have not installed the spool holder or the ramps holder
09:53 PM zhanx: but check your email
09:56 PM rue_mohr: gahk, you need a descent camera
09:56 PM zhanx: true
09:56 PM rue_mohr: ... wtf is the tape on there for?
09:56 PM zhanx: you told me i needed it
09:56 PM rue_mohr: your using 3mm or 1.75mm pla?
09:57 PM zhanx: 1.75
09:57 PM rue_mohr: no, the tape on the left z
09:57 PM zhanx: oh kids
09:57 PM rue_mohr: what is making the y motor cookid like that?
09:57 PM zhanx: i melted t
09:57 PM zhanx: it
09:57 PM rue_mohr: oh, heatgun, easy fix
09:57 PM zhanx: henced printing a new one
09:57 PM rue_mohr: oh
09:57 PM rue_mohr: k
09:57 PM zhanx: or that
09:58 PM rue_mohr: it looks like your printing a carriage tho
09:58 PM zhanx: i am printing a how set
09:58 PM zhanx: a new set
09:58 PM rue_mohr: I have better parts for ya
09:58 PM rue_mohr: well, hmm, you want to try my improved parts?
09:58 PM zhanx: ok these are for jeff ^kat^ 's friend
09:58 PM zhanx: sure
09:58 PM rue_mohr: you need some other bearsings from china...
09:59 PM zhanx: email or link here
09:59 PM rue_mohr: ok, let me focus tho
10:00 PM rue_mohr: ok, lets get your machine some excersize before we make part upgrades
10:00 PM rue_mohr: but definitly the spool holder and the arduino holder
10:00 PM zhanx: made both
10:00 PM rue_mohr: so, you gonna make the arduino holder 'next' ?
10:00 PM rue_mohr: ok, which spool holder did you do?
10:00 PM zhanx: i have been printing so far for 2 days on it
10:01 PM rue_mohr: heh
10:01 PM zhanx: the top mount
10:01 PM rue_mohr: get the spool holder set up 'next'
10:01 PM zhanx: but due to my hobble hobbed bolt i am not using it
10:01 PM rue_mohr: and prolly replace that Y motor mount or fix with heatgun
10:02 PM zhanx: printing one before I try to fix it
10:02 PM rue_mohr: aaah ok, you can print a idler lever with filament guide
10:02 PM rue_mohr: its a little fork that reaches over the top
10:02 PM zhanx: link m
10:02 PM zhanx: me
10:02 PM rue_mohr: I have browser problem search for "filament guide"
10:02 PM rue_mohr: see what you can find for your parts
10:03 PM rue_mohr: I have to quick go zipcut some metal before dark
10:03 PM zhanx: k
10:45 PM rue_mohr: ok, the corkscrewed pipe was cut in 3, and had the splicers welded in
10:45 PM ^kat^: o
10:46 PM rue_mohr: later I'll grind the welds to them (just messy tacks) and weld the whole ring togethor
10:46 PM rue_mohr: it looks good and straight in 3rds :)
10:46 PM ^kat^: afk to fix a bite to eat
10:46 PM ^kat^: you twisted the pipe as you rolledit?
10:56 PM * furrywolf follows kat to see what there is to snack on
11:00 PM ^kat^: a ramen, adding mackrel and veggies, hot sauce and salt
11:00 PM ^kat^: bak
11:00 PM * furrywolf eats!
11:02 PM rue_mohr: ^kat^, yes, the pipe corkscrewed in the bender
11:02 PM rue_mohr: last peice to do that, I fixed it
11:03 PM rue_mohr: turns out I thought the pipe wend thru level with the bender, so I'd leveled the in/out tables
11:03 PM rue_mohr: it wasn't the bender takes the pipe thru on an angle, so I matched the tables and everything is ok
11:03 PM * ^kat^ nods
11:04 PM rue_mohr: there are 3 more rings to make, I have one almost ready to weld and 2 to do everything for
11:05 PM rue_mohr: I'v not worked out bearings yet, my brainstorm idea is to use discrete assembly bushings
11:05 PM ^kat^: do you have a good large flat to align them with?
11:06 PM ^kat^: use self-alligning "pillow block" bearings, better than bushings
11:06 PM rue_mohr: I made a special table
11:07 PM ^kat^: there;s an olde trick to making ultraflat tables, or portions of the table
11:07 PM rue_mohr: ooo that russian site did something to my browser
11:08 PM rue_mohr: I'll show you when my browser starts responding again
11:08 PM furrywolf: only russian site I usually use is rutracker. one of the best sites ever.
11:08 PM ^kat^: you run noscript and ABP and Ghostery and a profile spoofer?
11:09 PM furrywolf: I don't even know what two of those are.
11:09 PM rue_mohr: no I'm having challanges with a working 32bit browser
11:09 PM ^kat^: the russin site rue speaks of did nothing to me
11:09 PM ^kat^: 32bit here too
11:10 PM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1100581.jpg
11:10 PM rue_mohr: electronically adjustable auto-leveling table
11:10 PM rue_mohr: :)
11:11 PM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1100309.jpg <--- ring 1
11:11 PM ^kat^: ah, doubled rings
11:11 PM rue_mohr: its just EMT
11:12 PM rue_mohr: so I'm going for compression-tension mode
11:12 PM ^kat^: why is your new workshed so dirty?
11:12 PM rue_mohr: thats the house
11:12 PM ^kat^: oh
11:12 PM rue_mohr: "blow it up, start all over again"
11:13 PM ^kat^: i resumed work on mine, you can work on yours too
11:13 PM rue_mohr: :)
11:13 PM rue_mohr: I have till the end of Dec to decide on a design
11:14 PM rue_mohr: setting those rings parallel to each other and welding in the spacers was a MUCH larger challange than I'd expected
11:14 PM ^kat^: i'd post a pic, but don;t feel like wasting time in that way
11:15 PM ^kat^: why a challenge?
11:15 PM rue_mohr: a) finding the right position b) keeping the ring there, at the right distance while I tacked it
11:15 PM ^kat^: make a few [ brackets to sit them in, add the spacer, clamp all firmly
11:16 PM rue_mohr: ... [ bracket...?
11:16 PM rue_mohr: oh, long ones?
11:16 PM ^kat^: ok, make one reversed ]
11:16 PM rue_mohr: [=====
11:16 PM ^kat^: ----
11:16 PM ^kat^: |O
11:16 PM ^kat^: |
11:16 PM ^kat^: |O
11:16 PM ^kat^: ----
11:16 PM rue_mohr: oh
11:16 PM rue_mohr: oooh...
11:17 PM rue_mohr: huh
11:17 PM rue_mohr: well, thats a good idea
11:17 PM rue_mohr: kat, master fabricator
11:17 PM ^kat^: the uprights at 90 to the long span, several, will hold the rings right above each other, and give you clamping spots
11:17 PM ^kat^: it's the basis for my ring maker too
11:18 PM ^kat^: which, btw, it so flat i cannot measuer any offset
11:21 PM rue_mohr: I'll see how well I can do that on the next one
11:21 PM rue_mohr: the first bi-ring is pretty good, I know its pretty far out, but its not that bad once its all togethor
11:22 PM rue_mohr: I have bigger challanges
11:22 PM rue_mohr: https://www.xtreme-events.de/wp-content/uploads/aerotrim-verleih.jpg
11:22 PM rue_mohr: these things are pretty big, where to put it and how to get it there will be issues
11:22 PM rue_mohr: not to mention bearings/bushings
11:22 PM rue_mohr: and I have to get power and data thru them
11:22 PM rue_mohr: not wifi, too much latency
11:23 PM rue_mohr: I have like 20mins left to live and NOW I get interested in doing things
11:23 PM rue_mohr: ARG
11:24 PM ^kat^: http://designerthinking.com/images/IMG_0029.jpg , the turntable the ring is sitting on is ultraflat, the uprights are 90 to the channel to the other side where is anotehr upright
11:25 PM ^kat^: http://designerthinking.com/images/DSCF7135m.jpg where i was in the renewed house construction last month
11:25 PM rue_mohr: mmm such nice rings
11:25 PM rue_mohr: that looks like a challange to sheet
11:25 PM ^kat^: i put up jigs to hold the sheet
11:26 PM ^kat^: i did the compound miters freehand
11:26 PM rue_mohr: nice
11:26 PM rue_mohr: whats with the chain?
11:27 PM ^kat^: two-level scaffolding
11:27 PM ^kat^: the 6ft is on 6ft tall sawhorses, the 7ft level so i can work on the upper part iof the ceiling, sits on the lower and hang from the steel beam
11:28 PM rue_mohr: why ply and not drywall?
11:28 PM ^kat^: http://designerthinking.com/images/DSCF9036m.jpg
11:29 PM ^kat^: osb , because i got 40 sheets left, it;s lighter, structurally stronger than sheetrock, and i can still skimcoat it with plaster
11:29 PM rue_mohr: ok
11:30 PM rue_mohr: the upper osb is the roof , right?
11:30 PM ^kat^: yeas
11:31 PM ^kat^: tin above that
11:31 PM rue_mohr: trusses only every 4' ? is that cause of the metal roof?
11:31 PM rue_mohr: ours are 2'
11:31 PM ^kat^: those peaks is where i put skylites, and could standd up a 16ft lumber and not touch the peak
11:31 PM ^kat^: yeas, i cheated
11:32 PM rue_mohr: k
11:32 PM ^kat^: it holds me, i put the roof on it, altho i stayed on the ladder, it';s at a 45 deg pitch, you canot walk on it anyhow
11:32 PM rue_mohr: are your walls double -thick with foam insulation?
11:32 PM ^kat^: fiberglas :-(
11:32 PM rue_mohr: the white?
11:33 PM ^kat^: R50 down here, i dunno if i will go over the R30 i already have upstairs
11:33 PM ^kat^: the white is plaster skim on osb
11:33 PM rue_mohr: so the walls are double thick then?
11:34 PM rue_mohr: 4"+osb+4"?
11:34 PM ^kat^: the white behind the ring is cement, cast in the form where it sits, rebar in it
11:34 PM rue_mohr: oooh
11:34 PM rue_mohr: ok
11:35 PM ^kat^: no, 1/4 osb, 6" R30, 1/4 osb (putting the 2x4 for R19 up to hold the new ceiling now)
11:35 PM rue_mohr: yea, lots of people here put 2x2 or 1x4 strapping on those foam things and drywall to that
11:35 PM rue_mohr: horrid for doing electrical
11:35 PM rue_mohr: ah
11:35 PM ^kat^: i can later open where the skylites were to go, and blow in blow-in insulation, then reseal the holes
11:36 PM rue_mohr: :/ I need to make supper
11:36 PM ^kat^: that can be done on the flat roof, so no insulation blowing inside the hosue
11:36 PM rue_mohr: "DO I HAVE TO EAAAAT???"
11:36 PM ^kat^: here, swallow this tube .....
11:37 PM rue_mohr: how do I port myself to a mechanical platform kat
11:37 PM rue_mohr: I didn't take biology and thats being a problem
11:37 PM ^kat^: i think you canot, i think you can only build a simulation of yourself
11:37 PM ^kat^: however, you can be a cyborg
11:38 PM rue_mohr: but once I'm 100% cyborg I'm there
11:38 PM ^kat^: you cannot replace your bio-brain
11:38 PM rue_mohr: I'v learned a lot
11:38 PM ^kat^: atm, you cannot even simulate that
11:38 PM rue_mohr: I think I can
11:39 PM ^kat^: k
11:39 PM rue_mohr: neato thing tho kat
11:39 PM rue_mohr: pulse based system
11:39 PM rue_mohr: turns out, the latency isn't the max pulse rate
11:39 PM rue_mohr: system operates in bursts
11:39 PM rue_mohr: I still cant work out how pfm logic works
11:40 PM rue_mohr: but its really closely tied to the AGC it uses
11:41 PM rue_mohr: think like an AGC schmitt, that works in a pulse mode
11:41 PM rue_mohr: I need to know more about what kind of logic can be made with that, to know what, more complex strutrues, could be used
11:42 PM ^kat^: the hardware is easy, it's the code that will fail you
11:42 PM rue_mohr: pretty sure its mostly state machine
11:42 PM rue_mohr: I think a lot can be achived with nerve-whispering
11:42 PM ^kat^: when i say "daisey" , do you think of Frankenstien?
11:42 PM rue_mohr: the reason for the pfm is to get around background noise issues,
11:43 PM rue_mohr: that background noise issue is crossover noise from other nerves
11:43 PM rue_mohr: PFM with AGC
11:44 PM rue_mohr: how do you make logic out of that
11:44 PM ^kat^: PFM carrying what data by what criteris to where?
11:44 PM rue_mohr: nerves are PFM
11:44 PM rue_mohr: they employ AGC to set the trigger point
11:45 PM rue_mohr: thats why pins-and-needles in numb nerves
11:45 PM ^kat^: and elbows generally operate less than 180 degrees, no reason to emulate that limitation either
11:45 PM rue_mohr: agc goes insane and you get noise
11:45 PM rue_mohr: unless your used to operting an eblbow that only goes 180
11:45 PM rue_mohr: (its more like 160)
11:46 PM ^kat^: (some people can hyperflex)
11:46 PM rue_mohr: (not me)
11:46 PM ^kat^: (or me, it;s dangerous, especaiily in falls)
11:48 PM ^kat^: the latest pics are the camera upstairs
11:50 PM * ^kat^ does a /who on mynick and yournick
11:56 PM * ^kat^ sets up a couple TDA7294 as the output driver of a psu that can be modulated up to 15khz, and some TIP transistors as current boosters
11:56 PM ^kat^: had to change my driving glasses up half a point last weekend
11:56 PM ^kat^: to "1.5" , whatever that is
11:57 PM rue_mohr: hmm
11:59 PM furrywolf: bbl, wolfy bedtime
11:59 PM rue_mohr: google upgraded the browser requirement again
11:59 PM rue_mohr: now image search doesn't work on a bunch of stuff
11:59 PM rue_mohr: oh and captchas wont work on it anymore either
