05:39 AM JT-Cave: not found because there is no page with that name
05:42 AM XXCoder: yo
07:42 AM NoGodDamnIdea: I have arrived
09:02 AM JavaBean|new|2 is now known as JavaBean
09:17 AM robotustra: JT-Cave, the question is why there is no page if there is a link to it?
10:25 AM JT-Cave: where is this link?
10:48 AM robotustra: JT-Cave, https://gnipsel.com/linuxcnc/gcode/index.html called "Module Index"
10:59 AM JT-Shop: oh I have no clue what that is or why it's there...
11:00 AM JT-Shop: sphinx added that to the page for some unknown reason
11:05 AM robotustra: but it's your page?
11:05 AM JT-Cave: I only create a text file and sphinx creates the html page
11:07 AM JT-Cave: https://gnipsel.com/mesa/7i96/index.html
11:07 AM JT-Cave: that link is on all my pages for some unknown reason
11:09 AM robotustra: because it's probably auto generated?
11:09 AM JT-Cave: found it, yes it's automaticly added when you run sphinx-quickstart
11:10 AM robotustra: JT-Cave, what is the input data for your generator?
11:12 AM JT-Cave: what do you mean input data?
11:13 AM robotustra: I mean what do you take as an input the genereate your gcode in your program. Or you just give the params of faces and pockets?
11:13 AM robotustra: as a numbers?
11:14 AM JT-Cave: yes, but actually the gui is a string not a number and I convert that string to a number
11:15 AM robotustra: got it, just a type of operation and some parameters
11:15 AM JT-Cave: aye, but pocket is not done yet
11:16 AM robotustra: I'm trying to do a bit different, like pycam, or simplified cad/cam
11:17 AM robotustra: just derive data from the solid geometry
11:17 AM JT-Cave: I'm not familiar with pycam
11:18 AM JT-Cave: I did write a program a few years back to import a dxf file
11:19 AM robotustra: https://a.fsdn.com/con/app/proj/pycam/screenshots/266878.jpg/max/max/1
11:19 AM robotustra: you just give the geometry and a tool and you gat your g-code
11:20 AM robotustra: but if you know more about the part, I mean how it was created you could generate more optimal code
11:21 AM * JT-Cave has finished lunch minute and goes back to the shop
12:38 PM -!- #linuxcnc mode set to +v by ChanServ
02:37 PM JT-Shop: skunkworks, did you connect encoder.xx.velocity to analogoutx to sim the tacho?
04:47 PM XXCoder: man ouch https://blogs.sciencemag.org/pipeline/archives/2006/03/08/how_not_to_do_it_liquid_nitrogen_tanks
04:47 PM XXCoder: comments is interesting to read too
04:48 PM XXCoder: sureits old but yeah interesting read
04:49 PM XXCoder: theres offical report pdf near end of comments
04:51 PM XXCoder: oh broken link drat
04:51 PM CloudEvil: Interested to know how the SpaceX 3000 ton or so nitrogen/oxygen/methane tanks are engineered. There is an inner 9m shell, an outer 12m shell, and pressure and filling between is unclear. Especially as they likely want to subcool the propellant in the tanks beyond the nominal temperature.
04:52 PM CloudEvil: The 'simple' way would be to pull a vacuum on the tank, but it doesn't seem engineered for that.
05:09 PM * JT-Shop should clean the shop
05:12 PM XXCoder: thats true for all shops in world
05:12 PM snakedLX is now known as snaked
05:17 PM * JT-Shop needs to dream up a wire stripper and clean all his copper while the price is so high
05:17 PM CloudEvil: Liquid nitrogen ball mill
05:18 PM XXCoder: saw couple interesting stripper for that jt
05:18 PM XXCoder: 3d printed ones
05:20 PM JT-Shop: wonder if they would be strong enough to work
05:21 PM XXCoder: think so though its been a while since i last saw it
05:23 PM XXCoder: cant find it
05:24 PM JT-Shop: https://www.amazon.com/StripMeister-Automatic-Wire-Stripping-Machine/dp/B00I9GJH9W
05:25 PM XXCoder: yeah it was essentally that in concept
05:26 PM JT-Shop: https://www.amazon.com/product-reviews//B00I9GJH9W/ref=acr_dpx_hist_1?ie=UTF8&filterByStar=one_star&reviewerType=all_reviews#reviews-filter-bar
05:26 PM JT-Shop: hmm don't look too good
05:28 PM XXCoder: "iked it for 4 hours till the feeder wheel completely wore out. feeder wheel is not covered by warranty and can be purchased for another $40.00. at a repair rate of $10 an hour and copper prices dropping it sure bites into your profit. "
05:28 PM XXCoder: likely butteralloy if it worn that fast
05:30 PM JT-Shop: I made one from a block of wood that worked ok on many sizes
05:30 PM XXCoder: im sure you used actually good blade wheel for it though
05:31 PM JT-Shop: just a utility knife blade
05:33 PM XXCoder: that'd work. cheap and its very easily replacable.
05:36 PM JT-Shop: biggest issue is keeping the wire centered on the blade... I have some ideas that might work
05:37 PM XXCoder: depending on how thick plastics is, you probably can use wedge to fix it
05:40 PM JT-Shop: I'm thinking of adjustable sides to center the wire...
05:42 PM JT-Shop: gotta figure out how to hold the blade or use a rotary blade from something...
05:44 PM XXCoder: you do have lathe?
05:44 PM XXCoder: make one out of tool steel it'll last long time
05:44 PM XXCoder: it dont have to be single one actually. if its rotatary, its easy to have more than one
05:45 PM XXCoder: which means coverings just fall off
05:45 PM JT-Shop: aye, I have two lathes, Samson the Tiawan manual and the CHNC
05:53 PM JT-Shop: rain all day and rest of the week
05:56 PM XXCoder: here its start of hot
05:56 PM XXCoder: 85f here
05:56 PM XXCoder: tomorrow 77f, 76f then cloudy at 68f, 67f
05:57 PM XXCoder: "preview" summer now
06:01 PM * JT-Shop wanders inside for the night
06:01 PM XXCoder: later
