12:05 AM rue_mohr: he just got me again
12:09 AM rue_mohr: no more answers for him!
02:46 AM rue_bed: https://www.oreilly.com/openbook/motif/vol6a/Vol6a_html/ch04.html
05:43 PM zhanx: rue_mohr, my extruder came in
05:43 PM zhanx: its bowden
07:02 PM rue_mohr: "long"
07:02 PM rue_mohr: why did you get that?
07:02 PM rue_mohr: you can just take the connector off and I think your ok
07:02 PM rue_mohr: unless it buckles too easy
07:02 PM zhanx: Connect was not on it
07:03 PM zhanx: filament is buckling and I was sent the wrong one
07:03 PM rue_mohr: ugh
07:03 PM zhanx: so
07:03 PM rue_mohr: I feel really horrid at this point to starting you on all this
07:03 PM zhanx: i am taking part the old one right now
07:03 PM rue_mohr: oh!@!!
07:03 PM rue_mohr: the stainless is the same!!!!!
07:03 PM zhanx: yes
07:04 PM rue_mohr: YES!!!!
07:13 PM zhanx: too bad the threaded tube is stuck in the old one
07:18 PM rue_mohr: whaaa you got a remover dont ya?
07:22 PM zhanx: nope
07:25 PM zhanx: i got the plastic tube out of the heat sink now
07:27 PM rue_mohr: thats a start
07:27 PM zhanx: can i run with it?\
07:27 PM rue_mohr: you dont ahve any screw removers in your car kit
07:27 PM zhanx: nope
07:27 PM rue_mohr: ok, cut the shank off a drillbit and make a reverse drill
07:28 PM rue_mohr: er, nevermind, I'm tired
07:29 PM Tom_itx: me 3
07:29 PM rue_mohr: almost dozed off
07:29 PM rue_mohr: z hit enter too loud and I snapped out of it
07:32 PM zhanx: ok test time
07:35 PM zhanx: ok i am extruding again!
07:36 PM rue_mohr: ok, so maybe next time rue says dont crank on the nozzel?
07:36 PM rue_mohr: how thin was it? I'v never broken one
07:36 PM rue_mohr: 0.2mm?
07:37 PM zhanx: ABOUT THAT
07:37 PM zhanx: oops
07:40 PM zhanx: also this red filament takes a higher temp
07:47 PM rue_mohr: I want to recal my first printer
07:47 PM rue_mohr: the numbers are set really crazy to make it work
07:48 PM rue_mohr: it thinks it has 2.5mm filament
07:48 PM rue_mohr: too tired, my eyes wont see straight
07:48 PM rue_mohr: getting dark out
07:48 PM rue_mohr: arg
07:59 PM zhanx: ok
07:59 PM zhanx: gonna do this
07:59 PM zhanx: order some more metal heat sinks
08:11 PM zhanx: there goes 5 more bucks
08:55 PM zhanx: ok PTE tubes suck. So I ordered all metal ones
09:28 PM rue_mohr: uh
09:28 PM rue_mohr: ifyou melted the ptfe your WAY too hot
09:29 PM rue_mohr: printing gears and stuff for buddys haloween costume
09:31 PM furrywolf: steampunk?
09:31 PM rue_mohr: big robot
09:32 PM rue_mohr: I'll get pics, he's making some big pullstring robot hands
09:32 PM furrywolf: kat was showing off pictures of steampunk girls in corsets the other day... seems kinda pointless...
09:32 PM rue_mohr: huh
09:32 PM rue_mohr: dunno, there is good and bad steampunk
09:32 PM rue_mohr: heard the song?
09:34 PM rue_mohr: https://www.youtube.com/watch?v=TFCuE5rHbPA
09:36 PM zhanx: rue_mohr, I didn't melt the ptfe, I bent it remember?
09:39 PM furrywolf: hot ptfe is supposed to be fairly toxic
09:39 PM rue_mohr: oh, it was in there?
09:39 PM rue_mohr: I suppose so
09:40 PM rue_mohr: furrywolf, https://www.youtube.com/watch?v=TFCuE5rHbPA
09:41 PM zhanx: when i over tightened the nozzle somehow I messed up the ptfe
09:41 PM rue_mohr: didn't the new one come with new ptfe?
09:41 PM zhanx: it did
09:42 PM zhanx: one sec
09:43 PM zhanx: https://www.aliexpress.com/item/Stainless-Steel-E3D-V6-Heat-Break-Hotend-Throat-M6-26mm-for-1-75-mm-3-00mm/32527135670.html
09:43 PM zhanx: that piece is still stuck in the heat sink
09:44 PM zhanx: So i ordered 3 more heatsinks and 3 more full metal throats.
09:44 PM zhanx: So if it happens again, i can swap and fix while its printing
09:45 PM zhanx: that and I only need 2 more motors and can make another printer soon
09:45 PM rue_mohr: I suspect you will find an amazing palette of new mistakes to make
09:46 PM zhanx: this one was due to crap filament
09:46 PM rue_mohr: I had 1.75 that hit almost 3mm in a lump
09:47 PM * furrywolf has never 3d-printed anything
09:47 PM rue_mohr: they gave me a refund for that one
09:47 PM zhanx: mistakes my mentor who said, hey this is easy
09:47 PM zhanx: this melts at 210
09:47 PM zhanx: the last 2 were 190-195
09:48 PM rue_mohr: hmm
09:48 PM furrywolf: I could stick an extruder on the router table, print 4ft by 8ft by 7.5in...
09:48 PM zhanx: its PLA but wow
09:48 PM zhanx: furrywolf, you could
09:48 PM rue_mohr: furrywolf, no, thermal shrinkage
09:49 PM rue_mohr: even a 20cm object usually has unmanagable curl
09:49 PM furrywolf: yet more evidence 3d printing sucks? :P
09:50 PM furrywolf: wouldn't a table that kept the part at approximately melting temperature help with that, combined with scaling up the print slightly?
09:52 PM rue_mohr: yup
09:52 PM furrywolf: that seems quite easy...
09:52 PM furrywolf: 210 in either unit isn't very hot.
09:53 PM zhanx: C
09:53 PM rue_mohr: how strong is your nozzel fan?
09:53 PM rue_mohr: carefull of that
09:54 PM rue_mohr: you dont want that heatsink getting too warm, it'll create a backup that wont impress you
09:54 PM zhanx: k
09:54 PM zhanx: mine keeps the heatsink cool
09:56 PM rue_mohr: ok, mine stalled yesterday and it bakced up about 15cm of filament IN the nozzel
09:56 PM furrywolf: are there extruder designs that do not suck?
09:57 PM rue_mohr: you use 'em right and their ok
09:57 PM furrywolf: that's not what I asked. :P
09:57 PM rue_mohr: I'm gonna make a water cooled one sometime
09:57 PM Tom_itx: 3d printing is in it's infancy
09:57 PM zhanx: they have some nice ones
09:57 PM zhanx: Tom_itx, is right on that
09:57 PM Tom_itx: our vo-tech has the largest one made
09:58 PM furrywolf: I was thinking about a different kind of printing earlier today... cnc wood burning. pinpoint propane torch? soldering iron? laser?
09:58 PM Tom_itx: http://tom-itx.no-ip.biz:81/~webpage/cnc/temp/prints/3d_printer1.jpg
09:59 PM Tom_itx: 3d printer
09:59 PM furrywolf: looks expensive.
10:00 PM Tom_itx: http://www.rpm-innovations.com/
10:01 PM zhanx: furrywolf, 10 years ago 3d printing at home was not really a thing
10:03 PM zhanx: and rue_mohr knows i am not mad about the printer breaking, I just got to learn more is all
10:05 PM furrywolf: so... best way to cnc burn wood in artistic fashion? I have a machine oxytorch...
10:09 PM rue_mohr: no I say laser
10:15 PM Tom_itx: one day everything will be 3d printed
10:15 PM * Tom_itx prints rue_mohr some supper
10:17 PM rue_mohr: that do _I want for supper!???!?!???!!!!!
10:17 PM rue_mohr: I WANT TO BE A ROBOT
10:18 PM rue_mohr: not sure how to handle object managment with this cam program
10:21 PM Tom_itx: will it handle rotary axis too?
10:21 PM Tom_itx is now known as Tom_L
10:22 PM Tom_L: someone in linuxcnc was talking about writing a 5axis cam program
10:24 PM furrywolf: I've talked about one too.
10:24 PM rue_mohr: yea, I been talking about a 2d cam for ... 97.. so... wait I got this...
10:24 PM furrywolf: talking doesn't result in a working product. :)
10:24 PM rue_mohr: 21 years now
10:25 PM rue_mohr: so lets wait till they have something
10:25 PM rue_mohr: after all so far 90% of the cm program out there are useless junk
10:25 PM furrywolf: I got as far as starting to write the simulator that was an integral part of the cam code, so it could keep track of what it had cut... and making it do tests like http://fw.bushytails.net/bunnytest01.png
10:26 PM Tom_L: i don't get why everyone must start over rather than taking one out there and fixing / finishing it
10:26 PM zhanx: Tom_L, that is what i am doing
10:26 PM rue_mohr: cause their utter crap
10:27 PM rue_mohr: sometimes by language
10:27 PM furrywolf: because everything out there is too utter shit to continue working on
10:27 PM rue_mohr: java? really?
10:27 PM Tom_L: what about freecad?
10:27 PM rue_mohr: I have a program that can take points and drill holes
10:27 PM rue_mohr: cad, not cam
10:27 PM Tom_L: ich was working on that and had done quite a bit but it was reported that he died
10:28 PM rue_mohr: and last time I tried freecad it crashed before I could draw a line
10:28 PM furrywolf: freecad is _buggy as hell_, as I suspect the bugs are due to systemic issues, not individual mistakes.
10:28 PM furrywolf: yep. freecad has about a thousand features, every one of which does the same thing... segfault.
10:28 PM Tom_L: rue_mohr, how long ago was that?
10:28 PM rue_mohr: dancad wouldn't start
10:28 PM zhanx: that is rue, I am gonna do this 3d scanner in java now
10:28 PM zhanx: wait i don't know java
10:28 PM furrywolf: I never got freecad to stay alive long enough to do anything, at all.
10:29 PM rue_mohr: cad isn't a problem for me
10:29 PM rue_mohr: I use librecad, its got bugs but doesn't crash and I can work around the issues
10:29 PM rue_mohr: but I need cam
10:29 PM Tom_L: ich was working on the cam part
10:29 PM Tom_L: had done quite a bit but that has stopped
10:29 PM rue_mohr: I cant remember the peice of junk I found before bamcam...
10:30 PM Tom_L: dan cad
10:30 PM Tom_L: maybe
10:30 PM Tom_L: hey wait...
10:30 PM Tom_L: :)
10:31 PM rue_shop5: bCNC
10:31 PM rue_shop5: its junk
10:32 PM rue_shop5: buts its the closest to what bamcam can do
10:34 PM Tom_L: https://www.freecadweb.org/wiki/Path_Workbench
10:34 PM rue_mohr: no tom, no, I'm writing one
10:35 PM rue_mohr: its been 21 years
10:35 PM rue_mohr: I been procrastinating long ennough
10:35 PM Tom_L: i think that's what he was working on
10:35 PM Tom_L: even as recent as maybe a month ago
10:36 PM Tom_L: he was a german and all his youtube etc was removed by his son
10:36 PM rue_mohr: GTK and opengl, yup
10:36 PM Tom_L: it was a great resource
10:36 PM Tom_L: gone
10:36 PM rue_mohr: if he were using QT it would land in the trash faster
10:37 PM rue_mohr: I should have started this 21 years ago
10:37 PM rue_mohr: in Qbasic
10:39 PM Tom_L: anyway, i thought it might be something you might wanna look at
10:39 PM Tom_L: gnite
10:40 PM rue_mohr: thanks
10:40 PM rue_mohr: I was thru it all, ended on bamcam
10:40 PM Tom_L: i doubt you saw that one
10:40 PM rue_mohr: I have soemthing like 20 more runs left to the evaluation
10:41 PM rue_mohr: I dont remember everything I tried, but apt-cache search freecad
10:41 PM rue_mohr: freecad - Extensible Open Source CAx program (alpha)
10:41 PM rue_mohr: pretty sure I tried it
10:41 PM Tom_L: i think this is an extension to freecad though
10:42 PM Tom_L: maybe a separate project as i understood it
10:42 PM Tom_L: because they wouldn't merge the work
10:42 PM Tom_L: then he died
10:42 PM rue_mohr: besides, most of the flipping cam programs want you to feed them an STL
10:42 PM rue_mohr: I WANT 2.5d
10:42 PM Tom_L: i'm not fond of stl
10:42 PM Tom_L: at all
10:43 PM rue_mohr: its ok if its high quality
10:43 PM rue_mohr: mostof the time its not
10:44 PM Tom_L: i prefer iges or sat or something like those
10:46 PM rue_mohr: its kinda insane how much of the code is just the gui stuff, not the part that even does anything
10:46 PM Tom_L: but they're both out of the realm of 2.5d
10:46 PM Tom_L: yeah, the work has to be portrayed to the user somehow
10:49 PM Tom_L: sheetcam is 2.5d
10:49 PM Tom_L: did you look at inkscape's addin?
10:51 PM rue_mohr: tom, 21 years, stop trying to make me put it off more!
10:52 PM rue_mohr: inkscape lacks someting really critital, scale!
10:52 PM Tom_L: yeah i don't like inkscape in general
10:53 PM rue_mohr: besides, something that NO cam software I'v ever seen can do, is to generate holes without using the canned gcode command
10:53 PM rue_mohr: my program doesn't hav a gui and it can already do that
10:53 PM rue_mohr: matter a fact, that version of it cant even open a dxf
10:54 PM Tom_L: i should get you to set mine up
10:54 PM rue_mohr: too fancy
10:55 PM Tom_L: i've got a dos 2.5 version
10:55 PM rue_mohr: all I want is mastercam
10:55 PM Tom_L: 2.5d
10:55 PM Tom_L: this was better than mastercam back when i bought it
10:55 PM rue_mohr: mastercam would be a awesome target
10:55 PM Tom_L: now most small shops use mastercam
10:56 PM rue_mohr: sounds like the one jester half installed and gave up on... wish he'd finished that
10:56 PM rue_mohr: but no
10:56 PM rue_mohr: I'm making a linux-only cam
10:56 PM Tom_L: yeah it is
10:56 PM Tom_L: the 3d version
10:56 PM Tom_L: but it will do it all
10:56 PM rue_mohr: linux deserves a working cam program
10:56 PM Tom_L: 2.5d , 3d, lathe etc
10:56 PM rue_mohr: 21 years!
10:56 PM Tom_L: of not giving in
10:56 PM Tom_L: :)
10:57 PM Tom_L: i bet i've had that software alot longer than that
10:57 PM rue_mohr: no, 21 years ago, I said "Bah, if I wait a bit, there will be a workable one for free"
10:58 PM Tom_L: life passes you by as you wait
10:58 PM rue_mohr: nobody told me that
11:00 PM Tom_L: you gotta pick n choose what you make, buy or do without
11:02 PM rue_mohr: 21 years of no cam software for linux
11:02 PM rue_mohr: wtf!?
11:03 PM rue_mohr: I'm still just working on gui stuff tho
11:03 PM rue_mohr: trying to catch up with the last 20 years of X11 programming
11:08 PM zhanx: ok table is controlled now by the software
11:09 PM zhanx: rue_mohr, should i take all the photos and then process them, or take and process then move?
11:10 PM rue_mohr: thread it
11:10 PM zhanx: I am thinking taking the photo process and then move
11:10 PM rue_mohr: one shoveling images into a cache the other feeding off it
11:10 PM zhanx: k
11:11 PM rue_mohr: design so you can have atealst 4 threads processing from the cache
11:11 PM rue_mohr: (multicore processor)
11:11 PM zhanx: I have 01 res on the table moving right now, I need to gear it down once the printer is back up
11:11 PM zhanx: .01
11:11 PM zhanx: I want 10x that
11:12 PM zhanx: takes 8 minutes right now to due a "basic"
11:14 PM rue_mohr: XmNwidth, 800, /* 5 inches */but can you see the line
11:15 PM rue_mohr: ...
11:15 PM rue_mohr: but can you see the line
11:16 PM rue_mohr: just tell me the horizontal offsets and the angle, I want to make a point cloud
11:18 PM zhanx: 2500 mm to center of point. offset of camera to laser 150mm, angle 22
11:18 PM zhanx: err 250m
11:18 PM zhanx: ugh
11:19 PM rue_mohr: well I need to know its at 22 degrees, but other than that I just need the offset of the line from the middle of the image, and the angle the object is at
11:19 PM rue_mohr: everything else just scales it
11:20 PM rue_mohr: hmm I have a 3d point/line library now too
11:20 PM furrywolf: apparantly talking about linux hardware drivers is spam, now. :P
11:20 PM rue_mohr: wonder if I can make it import stl..
11:20 PM furrywolf: https://paste.debian.net/1049663/
11:20 PM furrywolf: why I got klined.
11:20 PM rue_mohr: uh
11:20 PM furrywolf: rue_mohr: as the spambot expert, your job is to figure out how the hell that line even looks like spam. :P
11:21 PM rue_mohr: ... good question
11:21 PM furrywolf: #freenode removed my kline, but they won't tell me what it matched or how to avoid it in the future.
11:22 PM rue_mohr: hows the cnc?
11:22 PM rue_mohr: er, you said you moved the table, to where?
11:22 PM furrywolf: to my rental storage unit
11:23 PM rue_mohr: tahts a flipping big storage unit
11:23 PM zhanx: either way rue, the program is now controlling the table right
11:23 PM furrywolf: 12x24 nominal, more like 11x23... and it's filled with other stuff too.
11:24 PM zhanx: g code all the way for the laser scanner
11:26 PM furrywolf: I don't have any shop space here at all...
11:27 PM rue_mohr: furrywolf, I think you shoudl focus on getting the welder working
11:27 PM rue_mohr: you can make the cnc table a tilted-back and be closer to being able to use it
11:28 PM rue_mohr: kat has a broken back too, YOU CAN DO IT
11:28 PM rue_mohr: (use brain, not back)
11:28 PM furrywolf: I want to make the welder work too, because I want to re-design the legs of the table so I can roll things under the table for storage, and put it on casters too.
11:28 PM rue_mohr: yes, were agreed fix the welder!
11:28 PM zhanx: fyi rue_mohr I am trying to find a work around that is not crazy gstreamer (ubuntu) was broken again
11:28 PM rue_mohr: whats wrong with it!
11:29 PM rue_mohr: whats gstreamer?
11:29 PM zhanx: cam software for 18.04
11:29 PM rue_mohr: ok
11:29 PM zhanx: they broke it again
11:29 PM rue_mohr: must be QT
11:29 PM zhanx: it is
11:29 PM rue_mohr: whats motion use?
11:29 PM zhanx: not sure
11:29 PM rue_mohr: AAAAND HE'S OFF!
11:29 PM rue_mohr: ?
11:30 PM * rue_mohr hurds zhanx along in the direction of 'motion'
11:30 PM zhanx: lol
11:30 PM zhanx: k
11:31 PM rue_mohr: :) I'd help more, but I'm fighting my own battle here
11:31 PM zhanx: rue_mohr, you need to finish that cam program, if i am doing the scanner here
11:31 PM zhanx: :P
11:31 PM rue_mohr: http://paste.debian.net/1049666/
11:31 PM zhanx: oh i know i am fighting the battle of broken and outdated crap
11:32 PM zhanx: oh X11, not fun
11:32 PM zhanx: but i should use that also
11:32 PM rue_mohr: I'm gonna be SO thrilled to ahve the gui stuff out of the way and start importing my librearies that do things
11:33 PM zhanx: i need to make a gui
11:33 PM rue_mohr: just dont use QT or your stuff will have to be completely rewritten every 2 years
11:33 PM rue_mohr: and thats maintenance you dont want
11:33 PM zhanx: yea it seems everything is getting broke about that cycle
11:33 PM rue_mohr: mostly QT stuff
11:34 PM zhanx: hmmm
11:34 PM rue_mohr: they do things like change the argument count and types to fucntions with the same name
11:34 PM rue_mohr: between versions
11:34 PM zhanx: yea i found that out
11:34 PM zhanx: the hard way
11:34 PM rue_mohr: librecad is hanging on by a thread
11:35 PM rue_mohr: it cant keep up with the QT changes
11:35 PM furrywolf: a lot of software still uses qt4, because it hasn't been updated to qt5... good thing linux libraries happily coexist. :P
11:35 PM rue_mohr: in perspective, motif examples from '98 work just fine, the only tweeks being because gcc has changed
11:36 PM zhanx: gcc and webcams... ugh
11:36 PM rue_mohr: furrywolf, you have to completely rewrite the software, so programs that use QT will die
11:37 PM rue_mohr: the onlyproblem I have with gtk, is that its c++ centric
11:37 PM zhanx: with gcc I need to use Video4Linux which sucks
11:38 PM rue_mohr: http://images.livingthecountrylife.mdpcdn.com/sites/livingthecountrylife.com/files/styles/slide/public/hereford.jpg?itok=uiQO5zDZ
11:38 PM rue_mohr: its not a big beef
11:38 PM zhanx: i couldn't even get the latest version to compile for me
11:38 PM rue_mohr: uh
11:38 PM zhanx: just a ribeye not a t-bone yet
11:38 PM rue_mohr: even the other stuff uses v4l...
11:38 PM rue_mohr: v4l2 even
11:39 PM zhanx: v4l2 is forked and forked on ubuntu it seems
11:39 PM rue_mohr: gcc is just a compiler tho,
11:39 PM rue_mohr: should affect what video library you use
11:39 PM zhanx: only video that works "well" with gcc is v4l2
11:39 PM rue_mohr: what other video is there?
11:40 PM furrywolf: gcc doesn't care what kind of video you have. gcc is a compiler. lol
11:40 PM zhanx: I am using UCV right now
11:40 PM zhanx: furrywolf, its the dependds
11:40 PM zhanx: they are all fubar
11:41 PM zhanx: granted i might be fubar, but i can save images from the cam just not display them due to errors etc
11:41 PM rue_mohr: opencv doesn't deal with all that for you?
11:42 PM zhanx: opencv is outright now
11:42 PM zhanx: the opencv I need 1 thing from, that is it
11:42 PM zhanx: so i coded around it
11:43 PM zhanx: but then you said gui and i said ugh
11:43 PM furrywolf: I didn't mess with raw video when I was playing with laser scanning... I just used another program to grab stills.
11:43 PM zhanx: i am grabbing stills from raw straight to file
11:44 PM zhanx: tmp file is of course temp
11:45 PM zhanx: ok one more test, that last one had 2 extra grabs
11:45 PM zhanx: weird
11:46 PM zhanx: float is adding some numbers to the file name it should not
11:46 PM zhanx: file_name0.5399998.jpg but its adding .001 to zero not all the rest
11:47 PM zhanx: now what did i mess up
11:50 PM furrywolf: completely random hardware request: I'm trying to find two of these lamps: https://vintageinfo.be/kreo-folding-bedside-lamp/ anyone have one stuffed in a box in their attic they want to get rid of?
11:52 PM furrywolf: sold under a couple names, like https://www.shopnueve.com/chair-caned-and-lacquer-thonet-style-hexagonal/lighting-lloyd-s-fold-up-lamp/ too
11:52 PM zhanx: weird it took 1440 photos and all with the wrong file name
11:53 PM zhanx: xt = xt + .01; xt is a float
11:54 PM furrywolf: .01 doesn't float nicely. is that your error?
11:54 PM zhanx: its floating to .01xxxxx
11:55 PM furrywolf: yeah. floats do that. :P
11:55 PM furrywolf: print with %02f or something
11:55 PM zhanx: ?
11:55 PM zhanx: my brain is getting fried
11:56 PM furrywolf: .01 can not be represented exactly in base-2 floating point.
11:56 PM furrywolf: it's stored as an almost-but-not-quite approximation
11:56 PM zhanx: oh that is right I need to move it to .03
11:56 PM furrywolf: if you want to print it in two digits without random stuff, use the format specifier for whatever printf is in your language to specify only printing two digits.
11:57 PM zhanx: yep
11:57 PM zhanx: space cadet
11:59 PM furrywolf: a better question is why the hell do you have floats in your filenames? :)
11:59 PM zhanx: well, did i say i coded for a living?
