00:07 rue_shop2 ok its printed
00:07 rue_shop2 give me a min for images
00:13 rue_shop2 Tom_itx,
00:13 rue_shop2 http://imgur.com/tBeYolr
00:13 Tom_L will it fit
00:14 Tom_L ?
00:14 Tom_L that bottom side didn't print very good on the radius... i forgot about that
00:14 rue_shop2 wow, it really holds the bar!
00:14 e_shop2 tries to get it
00:14 Tom_L fit ok?
00:14 rue_shop2 yea, it hates the overhangs
00:15 Tom_L i could make that part squared off
00:15 rue_shop2 trying to get it off so I can test the 1/8"
00:15 Tom_L too tight?
00:16 rue_shop2 its the printer
00:16 Tom_L you mighthave to drill the 1/8 hole
00:16 rue_shop2 accurate holes are an issue
00:16 rue_shop2 yup
00:16 Tom_L want me to make it flat on the side?
00:16 Tom_L instead of round?
00:17 rue_shop2 its non crititcal
00:17 rue_shop2 huh, I swear my machine is out of square again
00:18 rue_shop2 springy plastic, rod dosn't like to take it drilled out to 1/8
00:18 rue_shop2 got it
00:18 rue_shop2 its tight
00:19 Tom_L it's supposed to be tight
00:19 rue_shop2 maybe I dont need to worry about holding screws
00:19 Tom_L isn't it?
00:19 rue_shop2 yea
00:19 rue_shop2 its to hold on a subframe for the control baords
00:19 Tom_L oh
00:19 Tom_L it should hold them
00:19 rue_shop2 damn, I cant get if off the 1/8 now
00:19 Tom_L get a .125 reamer
00:20 rue_shop2 hah, 22 days later...
00:20 rue_shop2 you see what the circile around its for tho eh?
00:21 rue_shop2 I could also scale it up by like 0.5%
00:21 Tom_L i about got one with a flat side...
00:22 rue_shop3 kinda cool to deisgn it there and print it here
00:22 rue_shop3 in the span of.. 30mins?
00:24 Tom_L took most of that to figure out how to draw it
00:24 rue_shop3 must make life on the space station interesting
00:24 rue_shop3 :)
00:24 e_shop3 prints his calibration square a
00:25 Tom_L ok i got a square one now...
00:25 Tom_L you can try that
00:26 Tom_L grab the file...
00:26 Tom_L you'll have to rotate it like you did the first one
00:27 Tom_L http://tom-itx.no-ip.biz:81/~webpage/rue/Rue_connector_square.STL
00:28 rue_shop3 now make a thingiverse account and upload it! :)
00:28 rue_shop3 or not
00:28 rue_shop3 I dont know if I trust makerbot
00:29 rue_shop3 they seem to be taking credit for the 3d printing revolution
00:29 Tom_L http://tom-itx.no-ip.biz:81/~webpage/rue/Rue_connector_square.jpg
00:29 Tom_L just filled in the rounded part
00:30 Tom_L you can use either one you want
00:30 rue_shop3 huh, its as square as its gonna get
00:31 Tom_L how long did that print take?
00:31 Tom_L 10 min?
00:31 rue_shop3 hold on, let me get your other going and I'll tell ya when I start
00:32 Tom_L that one will take more plastic
00:32 Tom_L since the corners are filled in
00:32 Tom_L better hurry, i'm goin to bed
00:33 rue_shop3 did you ...no
00:33 Tom_L no i didn't rotate it
00:33 Tom_L i haven't figured out how to change planes yet
00:34 rue_shop3 rotated
00:34 rue_shop3 takes me forever to find that in the menu
00:35 Tom_L you'll remember before long
00:35 Tom_L if i do very many
00:35 rue_shop3 heh
00:35 Tom_L it's good SW practice anyway
00:35 rue_shop3 slicing...
00:35 rue_shop3 done
00:36 rue_shop3 starting extruder heater...
00:36 rue_shop3 rezeroing
00:36 Tom_L 100% fill?
00:36 rue_shop3 hell no
00:36 rue_shop3 10%
00:36 rue_shop3 the way its printed the force isn't against the layers for the large rod
00:36 Tom_L so it's partially hollow?
00:36 rue_shop3 waiting for heat...
00:36 rue_shop3 yea crosshatch fill
00:36 rue_shop3 20%
00:37 rue_shop3 almost up to temp...
00:37 rue_shop3 printing...
00:38 rue_shop3 and I fogot to laod the file
00:38 Tom_L printing the first one again?
00:38 rue_shop3 technical difficulty, please stand by
00:39 rue_shop3 it was a tset square
00:39 rue_shop3 restarting...
00:39 rue_shop3 printing...
00:39 rue_shop3 increasing speed to 100%
00:42 rue_shop3 and its not 24cm of filament
00:42 rue_shop3 I got some ABS filament, gonna try it next time I think everything works great
00:43 Tom_L you seem awake now...
00:45 rue_shop3 my body is out of sync with my brain
00:45 rue_shop3 its half way thru the hole now
00:46 rue_shop3 did you use an extrusion for that?
00:46 Tom_L yes
00:47 Tom_L draw both flat profiles then extrude each one
00:47 Tom_L draw on 2 different planes
00:48 rue_shop3 do you think there is any chance the 1/8" hole is not quite at 90?
00:49 rue_shop3 I just saw a fill anomoly thats making me wonder
00:50 Tom_L no, it's 90 deg
00:50 Tom_L pretty sure of it
00:50 rue_shop3 ok
00:51 rue_shop3 the one I printed seems off, it might be an shrinkage issue
00:51 rue_shop3 print done!
00:51 rue_shop3 how long was that?
00:52 rue_shop3 I got 12 mins
00:52 Tom_L i dunno, i was figuring something out
00:52 Tom_L pics...
00:54 Tom_L i think i figured out how to orient it now
00:56 rue_shop2 http://imgur.com/g8YEmup
00:57 Tom_L that turned out better
01:00 rue_shop2 indeed, I'll run off a few
01:00 Tom_L wait!
01:00 Tom_L try this new file
01:00 rue_shop2 I dont think there is anythng else I want to print tonight
01:00 rue_shop2 shall I print or just do a slice test?
01:00 Tom_L grab the new square.stl file from my site
01:00 rue_shop2 your supposed to go to bed remmeber?
01:00 Tom_L see if it's oriented right...
01:01 rue_shop3 ok
01:01 Tom_L same part just turned over 90 deg
01:01 rue_shop3 http://tom-itx.no-ip.biz:81/~webpage/rue/Rue_connector_square.STL
01:01 rue_shop3 that one?
01:01 Tom_L yup
01:01 Tom_L i didn't flip the round one
01:01 rue_shop3 thats the right orientation
01:02 Tom_L good
01:02 rue_shop3 :)
01:02 Tom_L that wan't too hard to move
01:02 rue_shop3 congrads on your first 3d printed part thing
01:02 Tom_L those look alot better
01:03 rue_shop3 somthing else is odd, the clamp isn't centered
01:03 Tom_L it should be
01:03 rue_shop3 its askew to one side, ever so slightly
01:03 rue_shop3 oh
01:03 rue_shop3 cool then
01:03 Tom_L it should be dead nuts centered
01:03 rue_shop3 arg, my eyes keep ticking
01:04 Tom_L is the C too tight?
01:04 rue_shop3 I'd say its just right
01:04 Tom_L good WAG
01:04 rue_shop3 its a tight fit
01:05 Tom_L i'll have to figure out that angle and remember it
01:05 Tom_L maybe 10 deg or so
01:06 rue_shop3 they could be centered,
01:06 Tom_itx later..
01:06 rue_shop3 I should get this heated bed going
01:06 rue_shop3 need it for the ABS
01:07 Tom_itx yup
01:07 Tom_itx how many of those do you need? 4?
01:07 Tom_itx to hold the boards
01:23 rue_shop3 well
01:23 rue_shop3 I need between 2 and 3 cross bars, so I'm printing 6 more
01:24 rue_shop3 then I need holders to either clamp the board to the 1/8 or 1/8 verticles to the 1/8 horizontals
01:24 rue_shop3 so I need 1/8 to pcb, and maybe 1/8 to 1/8
01:25 rue_shop3 I think I'm over half way thru my black 1kg
01:25 rue_shop3 dont know where it all went :/
01:25 rue_shop3 tho...
01:25 e_shop3 looks at the pcb clamp and the spool holde
01:25 rue_shop3 I can guess where most of it went
01:26 rue_shop3 http://uk.farnell.com/productimages/standard/en_GB/42350821.jpg
01:26 rue_shop3 I have one of those, want more, so I cadded up the end and printed one
01:31 rue_shop3 yaknow, a machine screw would thread right into that 1/8 hole, tight
01:48 rue_shop3 Tom_itx, one day there is gonna be a commercial that advertizes a downloadable product that you need to pay a dollar for, to print, and it'll be all drm so you can only print one
01:48 rue_shop3 posibly just a data stream lease, so technically you dont get the file
01:49 rue_shop3 anyhow I have 6 more clips now!
01:49 rue_shop3 :)
02:15 rue_shop3 I think rifraf just revealed another way of calibrating the plot width
02:15 RifRaf huh?
02:16 rue_shop3 the interlocking tabs on your gripper sides
02:16 rue_shop3 they dont match, if my width were correct, I bet they would
02:18 rue_shop3 I have to do bridge calibration
02:18 rue_shop3 but I want to print a new feeder
02:18 RifRaf the parts should fit together ok with not more than a minor quick sanding if anything
02:18 rue_shop3 the male tabs are really small
02:18 RifRaf but i have changed the gripper, still need some time to finish it so it all press clips together
02:18 rue_shop3 I been trying to work out how to adjust the nozzel size right
02:19 rue_shop3 I'm printing what you gave me
02:19 rue_shop3 I'll play
02:19 RifRaf ok, if i was more awake would do some now but still hung over
02:20 rue_shop3 lots more to do
02:20 rue_shop3 tom designed some clips that will be part of my circuit board mounting system
02:20 RifRaf yep saw them before
02:23 rue_shop3 this is crazy, I want to make a new extruder, and there are so many variations of machines, I'm having trouble working out which ones are compatible with my carrige
02:25 rue_shop3 lots of direct drive extruders
02:25 RifRaf geared is good
02:25 rue_shop3 yes, tho playing, it dosnt' seem to take much force if everything is working properly
09:46 Tom_itx should the 1/8" to 1/8" be parallel or 90 deg from each other?
09:47 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/rue/reprap/Rue_connector_pcb_mount.jpg
09:47 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/rue/reprap/Connector_125_125.jpg
09:47 Tom_itx i moved them all to that folder
10:11 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/rue/reprap/Connector_rnd_125_125.jpg
10:16 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/rue/reprap/Conn_rnd_125_125_short.jpg
10:16 Tom_itx that one is .250 bet centers
10:17 Tom_itx the other one is .375
10:22 rue_bed heh, no sleep?
10:22 rue_bed unfortunatly, at 90*
10:23 rue_bed the idea is to make a grid of bars that allow for where you want to place the pcb
10:25 Tom_itx can do
10:25 Tom_itx .250 apart or .375?
10:25 rue_bed last night I was thinking that a snap/snap connector for hte 1/8 might work
10:25 rue_bed it can be right tight
10:25 Tom_itx well of course you would
10:25 rue_bed prolly the closer the better on that
10:26 Tom_itx i'll have to do some calcs
10:26 m_itx scratches his
10:26 Tom_itx can't be 2 snaps at 90 deg
10:26 Tom_itx wouldn't print good
10:27 rue_bed hmm
10:30 Tom_itx got your 90 done
10:32 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/rue/reprap/Connector_125_125_90.jpg
10:32 rue_bed heh, I'm not awake yet
10:32 Tom_itx get that thing warmed up!!!
10:33 Tom_itx i bet i could round those too but it wouldn't print as good
10:43 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/rue/reprap/Connector_125_125_X3.jpg
10:43 Tom_itx 90 deg with end holes
10:44 rue_bed hmmm
10:44 rue_bed I have yet to wake up
10:44 Tom_itx want holes thru the corners too?
10:44 Tom_itx that will take a bit longer...
10:44 Tom_itx and it would look like swiss cheese
11:12 Tom_itx oh you mean with a mounting screw?
11:26 rue_more http://www.ebay.ca/itm/E-Z-Link-093-4-40-Wire-Extra-packages-shipped-free-Du-Bro-Number-885-/121303663806
11:26 rue_more there is a good printing candidate
11:27 rue_more the 1/8 hole is small enough to thread a #6 machine screw into
11:27 rue_more there was a power outage
11:27 Tom_itx saw that
11:28 rue_more breakfast...
11:28 rue_more robotics in an hour
11:28 Tom_itx warm up that printer
11:39 Tom_itx what diameter is that rod?
11:39 Tom_itx nm.
11:39 Tom_itx .093
11:40 Tom_itx can you do 1/16" wall?
11:40 rue_more I dont like to go smaller than 2mm
11:40 Tom_itx inch?
11:40 Tom_itx .125
11:40 rue_more zippo:/morfiles/doc/drafting# units 2mm inch
11:40 rue_more * 0.078740157
11:41 rue_more the rod is 1/8"
11:41 Tom_itx no it isn't
11:41 Tom_itx read the link
11:41 rue_more hu?
11:41 rue_more which link?
11:41 Tom_itx for the clip ends
11:41 Tom_itx servo clips
11:41 rue_more ooh
11:41 rue_more heh
11:42 e_more tries to work out which side of the map tom is on
11:42 rue_more Tom_itx, I think your having fun
11:42 Tom_itx dead in the middle
11:42 Tom_itx i'm learning solidworks
11:42 rue_more of course
11:42 rue_more you have the same problem as I do with the printer, to calibrate it I need to print things
11:43 SquirrelCZECH that url in topic doesn't work :P :)
11:43 rue_more to learn, you have to make things
11:43 Tom_itx can you print the clip facing up?
11:43 rue_more just avoid overhangs
11:43 rue_more bridges are ok, overhangs aren't cool
11:43 rue_more SquirrelCZECH, toms?
11:43 Tom_itx it's an upward facing C
11:43 SquirrelCZECH rue_more: yep
11:43 Tom_itx can you print the clip facing up?
11:43 SquirrelCZECH btw: solve overhangs with support
11:44 rue_more Tom_itx, your page down?
11:44 Tom_itx no it's probably a bad link from dyn
11:44 rue_more SquirrelCZECH, my machine screws up supports
11:44 rue_more its ddns
11:44 SquirrelCZECH hmm
11:44 rue_more http://tom-itx.ddns01.com:81/~webpage/index.php
11:44 Tom_itx change it to no-ip.biz
11:44 rue_more oooh
11:44 Tom_itx that one quit on me
11:44 e_more suit
11:45 rue_more changed topic of #robotics to: Arduino controlled, 3d printed psycho robots! | http://tom-itx.no-ip.biz:81/~webpage/index.php | happy hour at 2am GMT!
11:45 rue_more SquirrelCZECH, does it work now?
11:45 SquirrelCZECH yep
11:46 rue_more yay
11:51 uirrelCZECH is going to kill hi
12:04 SquirrelCZECH https://cloud.veverak.org/public.php?service=files&t=f279b8dcba2e9191c2f6ce838ced1194
12:04 SquirrelCZECH and I am DONE
12:05 iveevue What is that link=
12:05 SquirrelCZECH owncloud
12:06 SquirrelCZECH aaaand it should show a picture :)
12:06 ace4016 i believe it does
12:06 ace4016 looks like tank treads
12:06 iveevue s/=/?/
12:06 ace4016 and gearing
12:08 SquirrelCZECH ace4016: that's exactly what it is
12:22 SquirrelCZECH hard point: everything on the picture is parametric
12:23 SquirrelCZECH dimensions, thickness, posiiton of all that things
12:23 SquirrelCZECH so it's pretty easy to change anything :)
12:26 SquirrelCZECH only thing I need to find
12:26 SquirrelCZECH is bearings
12:26 SquirrelCZECH just now I picked 5x10x10 dimension
12:27 SquirrelCZECH but need something cheap ... thought about scrapping the bearings from something but no clue :/
12:29 SquirrelCZECH *5x10x5
12:59 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/rue/reprap/Servo_clip.jpg
13:53 RifRaf should be learning opemscad
13:53 RifRaf openscad*
13:55 deshipu openscad is nice
13:55 RifRaf SquirrelCZECH, great work on yur parts, printed them yet?
13:56 SquirrelCZECH that's actually half scad
13:56 SquirrelCZECH other half is my python library
13:56 SquirrelCZECH RifRaf: nope, still design process
13:56 RifRaf and the bearing you finding 5mm id, 10mm od and 10mm wide?
13:56 SquirrelCZECH but made some prototypes
13:56 SquirrelCZECH :)
13:56 SquirrelCZECH and that airless wheels are awesome
13:56 SquirrelCZECH RifRaf: whatever dimensions
13:56 RifRaf like a gimbal?
13:57 SquirrelCZECH it's fully parametric model, so I can modify for any bearing
13:57 RifRaf ok then maybe a 624 or something, they are cheap as when you get 100 or so
13:57 SquirrelCZECH http://www.ebay.com/itm/10pcs-Miniature-Rubber-Sealed-Metal-Shielded-Metric-Radial-Ball-Bearing-Model-37-/390773907375?pt=LH_DefaultDomain_0&var=&hash=item5afbf09faf
13:57 SquirrelCZECH found this
13:58 SquirrelCZECH MR63-ZZ 3x6x2.5 looks awesome to me
13:58 SquirrelCZECH RifRaf: http://i.dailymail.co.uk/i/pix/2013/03/07/article-0-1881423B000005DC-350_634x450.jpg
13:58 SquirrelCZECH that thingie on that picture uses same system of suspension :)
13:58 SquirrelCZECH and prototypes of it ... well it looks awesome! :D
14:00 RifRaf i wonder how long that will last in abs? pla would be too brittle
14:03 uirrelCZECH is using ABS by def
14:03 SquirrelCZECH well, first prototype was able to hold 3kg of pressure
14:03 SquirrelCZECH over 5kg
14:03 SquirrelCZECH :)
14:03 SquirrelCZECH *over 3kg
14:03 SquirrelCZECH and that was only 1mm thick ... "line" in that wheel
14:24 Veverak RifRaf: buuuut still too many things to design
14:25 Veverak the part with connecting motors and geared wheels will be tricky
14:25 Veverak :)
14:25 RifRaf looks like you are having fun designing though, and doing well
14:26 Veverak well
14:26 Veverak "doing well" can be said after it's working
14:26 Veverak but yeah, I like it :)
15:27 Tom_itx openscad is for reprappers
15:27 Tom_itx i don't fall in that category
15:44 RifRaf you are designing parts to be made on a reprap so i reckon you do
15:44 rue_shop2 heh
15:44 RifRaf though all your designs will not be usable by others
15:44 rue_shop2 I"m using his clips
15:44 rue_shop2 we have to rotate X by 90
16:00 Tom_itx if i drew it on a different workplane it would be ok
16:00 Tom_itx i think
16:00 deshipu how would you call the cathegory containing stuff like screws, nuts, bolts, washers, spacers, orings, etc.?
16:00 RifRaf [08:19] <mutley> and all other expressions like that, but im also mindful that i dont want to bash this point over and over as i dont want to upset you reifsnyderb
16:00 RifRaf [08:19] <reifsnyderb> mutley: Yeah, I got the idea. ;-)
16:00 RifRaf [08:20] *** pwillard3 quit (Read error: Connection reset by peer)
16:00 RifRaf [08:20] <mutley> reifsnyderb: i think you could get a lot of mileage out of it :)
16:00 RifRaf wow
16:00 Tom_itx deshipu, hardware
16:00 RifRaf just ignore that
16:01 RifRaf rotate([90,0,0])
16:01 deshipu Tom_itx: but I want to put things like chassis, wheels, electronic modules and boards, servos, motors, etc. separately
16:02 deshipu RifRaf: https://lh6.googleusercontent.com/-98bQJp5lINc/UssQyptY92I/AAAAAAAAUmc/r7XjbZ7UUro/w864-h572/Owl%2Btilted%2Bhead.jpg
16:03 RifRaf deshipu, fasteners
16:04 deshipu RifRaf: thanks
16:05 deshipu all I could come up with was "stuff" ;)
17:00 rue_shop3 ok I'm back, for a bit
17:00 rue_shop3 Tom_itx, what you come up with for brackets?
17:00 rue_shop3 I'm printing gear
17:00 rue_shop3 it seems that one of the robotics kids knew that inkscape can make gears
17:00 rue_shop3 go figure
17:13 Tom_itx rue_shop3, what brackets?
17:15 rue_shop3 you were working on 2 other brackets
17:15 Tom_itx they are all posted what i was working on
17:15 Tom_itx your clips
17:15 Tom_itx jpg for each one
17:16 Tom_itx the server hdd is starting to make noise
17:17 ShH hands Tom_itx the
17:17 GuShH come on that's pretty funny!
17:17 GuShH to an otherwise sad setup.
17:22 rue_shop3 Tom_itx, :/ its raid right?
17:22 rue_shop3 cat /proc/mdstat
17:22 rue_shop3 smartctl -a /dev/sda
17:30 deshipu GuShH: is that for Western Digital? ;)
17:48 just_corey Rue, here?
17:50 just_corey sdcard formatter for windows from the sd consortium
17:50 just_corey download here:https://www.sdcard.org/downloads/formatter_4/eula_windows/SDFormatterv4.zip
17:52 just_corey supposed to format cards for more efficient read/write times than defacto windows format which appearently improves acess time when used with arduino
17:53 just_corey that is all i have to report at this time
17:57 GuShH deshipu: hahahahaha
17:57 ShH g
17:57 Tom_itx rue_shop3, no
17:58 Tom_itx haven't backed up in ages either
19:54 rue_more just_corey, there are now two duo's lying on the floor
19:55 rue_more Tom_itx, better get on that...
19:58 rue_more and 2 more 8G cards
20:16 rue_shop3 grrr power outages
20:16 rue_shop3 just_corey, who did the origional of that screen adafruit?
20:20 just_corey huh?
20:20 just_corey Rue_shop3: please restate the question
20:21 just_corey oh the screen, yeah it was either Ada or sparkfun, but to be honest i think they both sell a clone of the same thing
20:22 just_corey i think it was Ada though
20:22 rue_shop3 it looks like theres an example on ada
20:23 rue_shop3 just load and run, right? ;)
20:25 just_corey thats the idea, load and go
20:26 just_corey so my dad just came to the door with a 512m fullsize sd card from my sister ( who hates my guts but appearently supports my insanity through electronics)
20:26 just_corey and looks like it shouldent be too much of a task to get the sd slot off the board in this reader from the $tore
20:27 rue_shop3 cool, AL, one of the guys who comes by (tested that card) said that of all places, the source, often has good deals on sd cards
20:27 rue_shop3 $9/16G
20:27 rue_shop3 !?! go figure
20:28 just_corey yeah ive seen them go on pretty good sale prices there
20:28 just_corey wierd pitch on this slot, not .1 spacing
20:30 just_corey micro slot appears to .05
20:36 just_corey well now im not sure if i should just go for it or wait till i get to your place tommorow
20:36 just_corey be nice if my mill could use sd cards so the technology is transferable
20:38 just_corey i suppose i have some printers in my bedroom on the hit list that have fullsize sd slots, i amagine i could prob strip one and turn their sd slot into a breakout, may even have the required buffer on the same pcb
20:39 st_corey is talking to the walls as u
20:43 rue_shop3 limited success with touchscreen
20:53 rue_shop3 no luck, have to go
