01:52 AM Deejay: moin
03:09 AM Loetmichel: hmm, just printed a replacement xacto-knife handle with an orange PLA spool that sat on the printer for 2 years now (company manufacturing floor, not humidity controlled). NOT BAD at all... especially for an Anet A8 :) -> http://www.cyrom.org/palbum/main.php?g2_itemId=17520&g2_imageViewsIndex=1
05:07 AM Tom_L: morning
05:26 AM jthornton: morning
05:27 AM XXCoder: morning
05:42 AM jthornton: wonderful my 7i96 configuration tool works with python 3.5 but gives me a syntax error with 3.7 about the import
05:44 AM XXCoder: bleh
05:44 AM XXCoder: version hell
05:48 AM jthornton: hmm something went wrong with the install
05:54 AM jthornton: https://www.thingiverse.com/thing:3778627 tried to print this but it fails at the shelf in the curve everytime
05:55 AM XXCoder: curve in z or y?
05:56 AM jthornton: curves from x to y
05:56 AM jthornton: the plastic just pulls away as it goes around the curve
05:58 AM jthornton: https://www.thingiverse.com/thing:476845 prints that pretty good
06:10 AM XXCoder: :)
06:10 AM Loetmichel: jthornton: i use these: https://www.thingiverse.com/thing:3065024
06:12 AM jthornton: thanks
06:13 AM jthornton: what is the cover for?
06:13 AM jthornton: and the wheel thing
06:13 AM Loetmichel: manal focus
06:13 AM Loetmichel: manual
06:31 AM jthornton: hmm debian 10 gives me a different install of the 7i96 tool
09:23 AM jthornton: Loetmichel, what print settings do you use on the Ender 3 for PLA?
09:24 AM Loetmichel: a lot of settings. mainly 60mm/sec (30mm first layer), 215°C hotend, 60°C bed.
09:24 AM Loetmichel: but i have pla that requires 215°C
09:37 AM jthornton: thanks
09:38 AM jthornton: my pla has a range of 195-230c IIRC
01:09 PM -!- #linuxcnc mode set to +v by ChanServ
01:55 PM Tom_L: jthornton, is the ender better than prusa?
01:55 PM jthornton: I think so
01:56 PM * jthornton is in Farmington MO this weekend
01:56 PM Tom_L: headin out to the fair in a bit
01:56 PM Tom_L: is it fairly easy to put together?
01:56 PM Tom_L: compared to the prusa
01:57 PM Tom_L: any mods you did etc?
01:57 PM jthornton: yea pretty easy to put together, I did machine the ends of the uprights to square them up better
01:57 PM jthornton: but that is not needed but I can't help it lol
01:58 PM jthornton: http://www.emcu.eu/configure-ultimaker-cura-software-for-use-the-creality-3d-printer-model-ender-3/
01:58 PM Tom_L: easy enough to do
01:58 PM jthornton: yea
01:59 PM Tom_L: you have to use cura?
01:59 PM Tom_L: or it's just better than the other stuff
01:59 PM jthornton: I had to shim the Z stepper mount to get the drive screw to be parallel to the upright but a nice aluminum one is coming
01:59 PM jthornton: no you don't have to use cura but it works and it's free
02:00 PM Tom_L: it's not the slicer is it?
02:00 PM Tom_L: just the control software?
02:00 PM Tom_L: i thought you used marlin
02:00 PM jthornton: it's been a while since I tried other slicers
02:00 PM Tom_L: ahh so cura is a slicer
02:00 PM Tom_L: what about pronterface?
02:00 PM jthornton: the printer had marlin, I have a Rpi3 with OctoPi connected and use that interface to run the printer
02:01 PM Tom_L: oh
02:01 PM jthornton: been a while since I tried pronterface
02:01 PM jthornton: so the work flow is take a .stl file and slice it in cura, load it with OctiPrint and run
02:04 PM jthornton: https://github.com/guysoft/OctoPi
02:04 PM Tom_L: what does it come with? a pi or arduino?
02:05 PM jthornton: arduino of some kind
02:05 PM Tom_L: 2560 i bet
02:05 PM jthornton: https://all3dp.com/2/ender-3-with-marlin-how-to-install-marlin-firmware-on-your-ender-3/
03:41 PM CaptHindsight: there are a bunch of different configs of Marlin out there...
03:41 PM CaptHindsight: what would actually help is for a non-dyslexic to clean up and comment the source
03:41 PM jthornton: yea
04:43 PM CaptHindsight: whats the fastest way to get plasma cut plate square into the mill?
04:43 PM CaptHindsight: angle grind the edges first where there is slag?
04:44 PM jthornton: I knock the dross off with a hammer but you still have the heat effected zone near the edge
04:44 PM CaptHindsight: clamp the parts by the center and mill off the ends?
04:45 PM CaptHindsight: 1/2" plate, we left 1/8" for dross and warping on each edge
04:45 PM CaptHindsight: A36 hot rolled
04:45 PM jthornton: you could just mill deep enough to get past the HEZ
04:46 PM CaptHindsight: looks like these parts were cut from the edge of a plate from the mill
04:46 PM Deejay: gn8
04:46 PM CaptHindsight: so only 3 sides plasma cut
04:47 PM CaptHindsight: I went back to the same supplier I had gotten some 1/2" drops from
04:48 PM CaptHindsight: the drops were shear cut, but they didn't know how they did that since their shear only goes to 1/4"
04:48 PM CaptHindsight: mystery drops
04:49 PM XXCoder: ghoooost 1/2" shear machine!
04:49 PM SpeedEvil: temp that can't read.
06:16 PM t4nk-freenode: fcol; now I'm facing some more idiotic behaviour... I setup a pic, but the bastard will not blink an led
06:16 PM t4nk-freenode: same setup as before
06:17 PM t4nk-freenode: but it will only show signs of being alive when I freaking touch one of the capacitors around the crystal *sigh*
06:17 PM XXCoder: youre acting as sink so maybe broken ground?
06:18 PM t4nk-freenode: yet when I load some usb device into the pic.. it seems to execute that code
06:18 PM * t4nk-freenode is really drastically ticked off
06:19 PM t4nk-freenode: I've experienced this problem b4, and I remember taking the tour around the house to try different outlets and all
06:19 PM t4nk-freenode: but there's something else up
06:21 PM t4nk-freenode: but it has to be ground related yeh
06:22 PM t4nk-freenode: how can I swap my body for a lead to ground ;)
06:22 PM XXCoder: lol well not sure. maybe check breaks though ground and up
06:24 PM XXCoder: lol https://www.youtube.com/watch?v=zamEvq8DecM
06:24 PM XXCoder: crystal touching made it work
06:24 PM XXCoder: funny if it was same issue as yours, dead crystal
06:27 PM t4nk-freenode: I just swapped it out, .. no luch
06:27 PM t4nk-freenode: luck
06:33 PM t4nk-freenode: well.. you got me onto something thoug... I switched to internal oscilator and it works
06:33 PM t4nk-freenode: *ponder*
06:33 PM jdh: they are disposable
06:34 PM t4nk-freenode: ?
06:35 PM jdh: life is too short for flakey hardware
06:37 PM t4nk-freenode: ah well, wouldn't want to make that an excuse though
06:45 PM t4nk-freenode: but it sure is flaky :|
06:46 PM t4nk-freenode: and these things ALways need to pop up when you're just on a roll
06:47 PM t4nk-freenode: I was really moving along nicely, exceptionally well since I always stall normally ;), and that was now several hours ago...
06:47 PM t4nk-freenode: the universe just has it in for me
06:48 PM t4nk-freenode: but, since life is too short indeed,.. intosc it will be for now :)) screw it
06:48 PM t4nk-freenode: thnx XXCoder :)
06:50 PM t4nk-freenode: very clever chap too, in that video; he tried soldering a crystal from another device into it, and 'wonders why it didn't work'
06:51 PM t4nk-freenode: 'it was a bit bigger'
07:16 PM t4nk-freenode: but shiny and metallic :)
07:17 PM t4nk-freenode: xtal is fine, caps are fine I think
07:17 PM t4nk-freenode: bloody mess.
07:30 PM XXCoder: t4nk-freenode: hes not professional
07:30 PM XXCoder: but its always interesting lol
07:30 PM XXCoder: suggest watch some others
07:30 PM XXCoder: he tend to get better across time lol
07:30 PM XXCoder: he does dumb stuff sometimes
07:51 PM XXCoder: maybe more your speed https://www.youtube.com/channel/UCYSAWDQnoz0uIBRYlophvNw
07:51 PM XXCoder: he restores shop then car
07:55 PM t4nk-freenode: ;) life is too short to while away on youtube
08:41 PM _unreal_: hello
08:41 PM XXCoder: yo
08:41 PM _unreal_: good lord just got back from dropping my daughter off to her mothers
08:41 PM _unreal_: 3.5 hours round trip
08:42 PM XXCoder: fun
08:42 PM _unreal_: lucky for me most of the time she does not take are daughter
08:42 PM _unreal_: I have primary regardless
09:45 PM _unreal_: ok just started milling my Z HEAD part
09:45 PM _unreal_: 3d milling 2 parts and 2d milling the rest
09:46 PM _unreal_: XXCoder, What would you say your average mill time is for most parts? 1hr ish
09:46 PM _unreal_: ?
09:47 PM _unreal_: and I'm talking stuff that requires smaller bits like 1/8th
09:47 PM _unreal_: for the precision
09:48 PM _unreal_: ?
09:52 PM * _unreal_ goes for a soda
09:54 PM XXCoder: varies
09:54 PM XXCoder: fro less than minute to 6 hours
09:54 PM XXCoder: tons is in 3-30 min
09:55 PM _unreal_: ! then again it depends on your machines ablites
09:56 PM XXCoder: sort of
09:56 PM XXCoder: hard metal jobs needs more skills
09:56 PM XXCoder: theres few jobs that we need to cut hardened metal blocks into parts
09:57 PM _unreal_: I've yet to try aluminum on my machine
09:57 PM _unreal_: I'm sure it would mill it just fine with the right feeds etc...
09:58 PM _unreal_: I'm cutting Starboard with a 1/8th upcut 3 flute 3mm per pass
09:59 PM _unreal_: I'm cutting at 350mm/m
10:00 PM _unreal_: I'm also saying I'm a lot
10:05 PM XXCoder: lol
10:06 PM XXCoder: doing cnc stuff for first time or machinist building a home machine?
10:07 PM _unreal_: home
10:07 PM _unreal_: I started CNCing back in the early 2000's
10:08 PM XXCoder: :)
10:08 PM _unreal_: its just software has gotten a lot easyer for making parts in the past 4 years and I just got my 3rd DIY cnc and ONLY on hand CNC working over the summer that I built back in 2k11
10:08 PM _unreal_: never finished
10:13 PM XXCoder: so finally finished one?
10:14 PM _unreal_: no just this one finally finished bilding this one
10:14 PM _unreal_: building
10:14 PM _unreal_: I started it just before my Xwife decided she was going to throw away her and are daughters lives and divorce me.
10:14 PM _unreal_: Kind of killed my motovtion
10:14 PM _unreal_: and $
10:16 PM _unreal_: My original first built one was VERY nigger rigged but it worked
10:17 PM _unreal_: second one was very big. sold that
10:17 PM _unreal_: all wood
10:17 PM _unreal_: then I moved to florida from maine been here since 2013
10:17 PM _unreal_: end of 2013
10:19 PM _unreal_: you know I find it amazing how many people have told me I was a fool for using threaded rod as my lead screw system on this machine. oh its going to ware out fast blaa blaa blaa
10:20 PM _unreal_: I have YET to have lost of any tolerance. I used coupler nuts as my "acme or drive" nuts. and I use white lithium grease as my lube on them.
10:20 PM Tom_L: my sherline had threaded rod
10:20 PM Tom_L: ballscrews are alot better
10:20 PM XXCoder: acme is ok
10:21 PM XXCoder: or did you mean allthread?
10:21 PM Tom_L: they may have been acme, i'm not really sure
10:21 PM _unreal_: allthread
10:21 PM _unreal_: I'm using threaded rod
10:21 PM _unreal_: standard 5/16 threaded rod
10:21 PM Tom_L: some are content with it
10:22 PM _unreal_: ya I get no squeaking no issues
10:22 PM _unreal_: and amazing torque
10:22 PM _unreal_: but my movements are slow
10:24 PM _unreal_: running my motors at there "max" before I risk loosing steps in a rapid. I'm pulling like 700 RPM giving me 14" a min or something like that
10:25 PM XXCoder: 14 ips isnt bad
10:25 PM XXCoder: er ipm
10:25 PM _unreal_: ya
10:26 PM _unreal_: nema 34 motor
10:26 PM Tom_L: i was getting 80ipm max on my sherline with a 20tpi screw
10:27 PM jthornton: Tom_L, looks like there are quite a few slicers out there now
10:27 PM Tom_L: wow you're still up!
10:27 PM Tom_L: :)
10:27 PM _unreal_: Tom_L, direct motor drive or belt?
10:27 PM _unreal_: slicers?
10:27 PM jthornton: just got back to the room
10:27 PM Tom_L: just got back
10:28 PM Tom_L: ahh that's right, you're away again
10:28 PM Tom_L: _unreal_ yeah we were talking about printers earlier
10:30 PM jthornton: not very far from home about 85 miles
10:30 PM _unreal_: hum
10:35 PM Tom_L: jthornton, does that printer come with a small nozzle?
10:35 PM jthornton: a normal 0.4mm nozzle
10:39 PM Tom_L: you get pretty fine results with it?
10:39 PM jthornton: so far, yes
10:40 PM jthornton: I still have a little tuning to do and found a good resource for the settings
10:41 PM Tom_L: if i ever get around to getting one i'll probably ask again
10:41 PM Tom_L: barely have room for the junk i currently have
10:41 PM jthornton: lol I hear that
10:42 PM XXCoder: heh yea
10:42 PM jthornton: what's cool is the printer can be anywhere you can get a cat5 cable to your lan
10:43 PM Tom_L: well that's pretty much anywhere on the property
10:43 PM Tom_L: does it work thru a switch ok?
10:44 PM jthornton: yea, I have a bunch of switches on my lan
10:44 PM Tom_L: i might have to add a small switch in the garage if i put it out there
10:44 PM Tom_L: got a 24 port inside
10:45 PM jthornton: after you install octopi on a rpi3 and plug it in you just open a browser anywhere on you lan and go to octopi.local IIRC
10:45 PM Tom_L: so i'd have to swap out the control that comes with it for a rpi
10:46 PM jthornton: no, the rpi is the interface that connects you to the printer
10:46 PM Tom_L: you lost me
10:46 PM jthornton: you plug a usb cable from the rpi to the ender 3
10:47 PM Tom_L: so you have 2 microcontrollers between the printer and the pc
10:47 PM Tom_L: the arduino _and_ the rpi
10:48 PM jthornton: the arduino is what runs the steppers and heaters, the rpi provides a web interface to your lan so you can load g code and monitor the printer very easy
10:48 PM Tom_L: yeah i get that, i just thought the rpi replaced it and added lan
10:48 PM Tom_L: so the rpi is in addition to it
10:49 PM jthornton: yep
10:49 PM Tom_L: and it has the web interface firmware on it for octopi
10:49 PM jthornton: yep
10:50 PM Tom_L: so octopi in essence is a router
10:50 PM Tom_L: not a cnc control
10:50 PM jthornton: no
10:50 PM Tom_L: well a web interface of some sort
10:50 PM jthornton: yea
10:51 PM Tom_L: will it handle more than one printer per pi?
10:51 PM jthornton: dunno
10:51 PM Tom_L: well get another one and try it!
10:51 PM Tom_L: i'm not sure how the school has all theirs set up
10:52 PM Tom_L: they run several different kinds
10:52 PM jthornton: I have a rpi on both printers
10:52 PM Tom_L: k
10:52 PM jthornton: each one has a different ip address
10:52 PM Tom_L: theirs were cloud based i believe
10:53 PM Tom_L: dunno what they were using
10:59 PM Lcvette: hello!
11:00 PM Tom_L: hi
11:02 PM Lcvette: can you see my posts or just the hello
11:02 PM Lcvette: was wondering if my matrix went out again
11:02 PM Lcvette: Tom_L: hows things?
11:11 PM Tom_L: just the hello
11:11 PM Tom_L: no matrix
11:28 PM Lcvette: Lol. Guess I fixed it again
11:28 PM Lcvette: \o/
11:29 PM Lcvette: Are you on master Tom_L ?
