12:09 AM rue_house: yay, i got some work done on arm10
12:11 AM rue_house: awe, there isn't even a folder for arm10 yet
01:02 AM opposition: Chimpanzee Corporate Culture Impressive - Chief Burger Zoo - Courtesy Telegraaf http://www.telegraaf.nl/dft/geld/werk-inkomen/27432211/__De_bedrijfscultuur_van_chimpansees__.html
01:29 AM rue_house: is that a bot?
01:32 AM zhanx: yep
01:34 AM rue_house: I wonder if I can use the esp8266 to detect joes phone and play "Hello joe" when it sees it try to connect to a wifi
01:35 AM rue_house: cause if its an open wifi network, the phone will try to connect automatically
01:35 AM zhanx: yes
01:36 AM zhanx: and i mean that
01:36 AM rue_house: I bet that would be a great way to catch thievs
01:36 AM rue_house: you log the prescence of their mac address
01:36 AM zhanx: yea its like a programmable router
01:36 AM zhanx: but not a router
01:38 AM zhanx: rue if your not adverse to it i can knock out the arduino crap code and tomorrow you can do it
01:39 AM zhanx: well edit it and check it etc
01:39 AM rue_house: dunno
01:39 AM rue_house: its just funny
01:39 AM rue_house: cause he leaves his bluetooth widget in the shop when he's here
01:40 AM rue_house: every time he walks back to the shop I can tell he's close cause the bluetooth reconnects
01:40 AM zhanx: can be fun
01:40 AM zhanx: relay it turn out all lights etc
01:40 AM rue_house: hah
01:40 AM rue_house: trigger the same song on the jukebox
01:41 AM zhanx: oh hello joe, we have decide we dont want you to handle us. click no light
01:42 AM rue_house: no I'm good with people randomly using the shop, it means that anyone casing the joint would just give up on grounds of the random traffic
01:42 AM zhanx: oh no just joe
01:42 AM zhanx: you can do the if x here do this if not do this
01:42 AM zhanx: you know that
01:42 AM rue_house: mac address to action table :)
01:42 AM zhanx: yep
01:43 AM rue_house: https://www.aliexpress.com/item/1-5KW-Water-Cooled-Spindle-Motor-Milling-Bearing-High-Grind-EXCELLENT-HIGH-LEVEL/32720189810.html
01:43 AM rue_house: still cant find a price to beat that
01:43 AM zhanx: heck my wife knows the password to my pc and it never works
01:43 AM rue_house: and its too expensive for me
01:43 AM zhanx: make one
01:43 AM zhanx: die grinder, ports etc
01:44 AM rue_house: I did, but the 45A (at 4V) the motor draws is an issue
01:44 AM zhanx: 4v?
01:44 AM zhanx: rue sometimes i do wonder
01:44 AM rue_house: did you see the cnc I did?
01:45 AM zhanx: that should be 24 or air powered
01:45 AM rue_house: its a 9.6V drill motor
01:45 AM rue_house: with a 12V supply
01:45 AM rue_house: its only a 23A supply
01:45 AM zhanx: i got a air compressor now
01:45 AM zhanx: my cnc is gonna be air over
01:45 AM rue_house: nice
01:46 AM rue_house: , but loud
01:46 AM zhanx: its a cnc who cares
01:46 AM rue_house: :) depends where it runs
01:46 AM zhanx: i live next to crappy neighbors
01:47 AM zhanx: but first is cedar canoe i need to do a father son thing this summer
01:49 AM rue_house: send the kid out on a canoe, dont hear of that one much anymore
01:49 AM rue_house: "ITS OK SON, THE TIDE WILL BRING YOU BACK IN, JUST KEEP PADDELING!"
01:50 AM rue_house: did you see the cnc machine I did?
01:51 AM zhanx: yes i did
01:51 AM zhanx: i asked for one remember?
01:51 AM rue_house: its working great, even after severly crashing it twice
01:52 AM rue_house: I got some I beam to make another one
01:52 AM rue_house: I'm excited
01:52 AM zhanx: i want to make a 3d cement printer 40' radius
01:53 AM zhanx: 8" movement with 20' height max
01:53 AM rue_house: nozzel size?
01:53 AM zhanx: 3/4" wide 1/8" thick
01:53 AM zhanx: print a house
01:54 AM rue_house: why not round and use an infill pattern for structure
01:54 AM zhanx: that is round
01:55 AM zhanx: 8" walls 80' diameter
01:55 AM zhanx: infill for structure
01:55 AM rue_house: I been thinking of that too, not any particular size
01:55 AM rue_house: but I'd like to 3d print wax first
01:56 AM zhanx: for me i have the size now. Wife wants it, need to do the math on concrete now
01:57 AM zhanx: she don't care what it looks like while being made, its after she wants to look good
02:02 AM rue_house: keep having apocolyptic nightmares...
02:02 AM rue_house: always a sunami
02:05 AM Jak_o_Shadows: rue, yeah, still having some issues with quality.
02:05 AM Jak_o_Shadows: The main one is probably bed height - the first few layers are squished.
02:05 AM Jak_o_Shadows: The bandingish typey thing I don't know - but isn't bothering me enough to fix.
02:06 AM Jak_o_Shadows: Also warping, but I have a heated chamber that it's not wearing, and the bed height will fix that partily
02:12 AM rue_house: your start height is wrong, bump it up a bit
02:12 AM rue_house: whats the first payer height set to?
02:13 AM rue_house: I recommend 0.3, with other layers being .025 or 0.2
02:13 AM zhanx: raft bed start?
02:13 AM rue_house: did you calibrate the extruders steps?
02:13 AM rue_house: no
02:13 AM rue_house: not much point, most of the time the damn thing wont come clean off the print
02:13 AM zhanx: well .03 is a normal raft
02:14 AM zhanx: not that i do more that research
02:14 AM rue_house: I find it good to do the first payer thicker, ANd have it overextruded, (about 120%)
02:15 AM rue_house: Jak_o_Shadows, gnight
02:15 AM Jak_o_Shadows: Night rue. Thanks
02:16 AM rue_bed: oh wait your awake
02:16 AM rue_bed: well answer the damn questions
02:16 AM rue_bed: :)
02:16 AM Jak_o_Shadows: The extruder steps I did the rough calibration.
02:16 AM Jak_o_Shadows: I have slic3r open now. Just looking for em
02:16 AM rue_bed: have a clip you can put on the filament?
02:17 AM Jak_o_Shadows: Yeah, 'spose.
02:17 AM rue_bed: clothespeg, paperclip, whatever
02:17 AM Jak_o_Shadows: First lyaer is 250%. Infill is 150% (which needs it - my infill tends to be a little thin for some reason).
02:17 AM rue_bed: put a clip on the filament, about 4cm up, heat it up and extrude 20mm, measure with ruler
02:18 AM Jak_o_Shadows: First layer speed is 50%.
02:18 AM rue_bed: hmm
02:18 AM Jak_o_Shadows: What part am I measuring?
02:18 AM Jak_o_Shadows: How much it's moved?
02:18 AM rue_bed: the amount the filament moved in
02:18 AM Jak_o_Shadows: Oh yeah, that one is all fine.
02:18 AM rue_bed: do you have any digital calipers?
02:18 AM Jak_o_Shadows: Checked that fairly recently
02:18 AM Jak_o_Shadows: Yep!
02:18 AM Jak_o_Shadows: The first layer height I have as 150% (of 0.2mm)
02:19 AM rue_bed: k, the overextrude forhte first layer, set to just 150%
02:19 AM Jak_o_Shadows: TBH, i think it may just be because the bed isn't exactly level.
02:19 AM rue_bed: well, adjust that too
02:19 AM rue_bed: whats your bed levinging system?
02:19 AM rue_bed: 3 or 4 screw
02:22 AM rue_bed: do you know how to tell if its the Z motors or the bed?
02:23 AM Jak_o_Shadows: 3 screws.
02:23 AM Jak_o_Shadows: That's a damn good point
02:23 AM Jak_o_Shadows: Erm, put a level on the x-axis rods?
02:23 AM Jak_o_Shadows: ./lots of measuring
02:23 AM rue_bed: do you have a square?
02:24 AM Jak_o_Shadows: yup.
02:24 AM Jak_o_Shadows: ~3
02:24 AM rue_bed: k, print a tower see if its cocked over
02:25 AM Jak_o_Shadows: ohhh. Like one 30+ tall? and see if it's perpendicular to the bed?
02:25 AM rue_bed: 20mm would do
02:25 AM rue_bed: look for the thingverse ruenahcmohr square check
02:26 AM rue_bed: it will also tell you if your xy is out
02:26 AM Jak_o_Shadows: I think you're juse rue mohr on thingiverse
02:28 AM Jak_o_Shadows: I wonder if canadian hose threads are the same as australian? https://www.thingiverse.com/thing:693149
02:29 AM Jak_o_Shadows: I can't print tonight btw rue - But thank you. First thing I'll print next time.
07:33 AM Snert__ is now known as Snert
06:55 PM rue_house: yup I want to make a 3d wax printer
06:55 PM rue_house: Jak_o_Shadows, did the cap work?
06:55 PM rue_house: I thougth everyone over there used quick-connects
06:57 PM orlock: what sort of wax?
06:57 PM orlock: and is this for investment casting? because i think pla works too
08:38 PM rue_bed: there are other things that can be done with wax tho
08:38 PM rue_bed: it keeps comming up
08:38 PM rue_bed: AND if I can do wax, I can do silicone
08:38 PM rue_bed: cant remember what I wanted to do with that,
