08:41 PM zhanx: ok designed more home lab stuff
08:45 PM zhanx: waiting on the glue to dry on the printer so i can print out my flask holder
08:45 PM Tom_L: i think i should make a separate macro for external threads instead of trying to make one do both
08:45 PM zhanx: i would
08:45 PM Tom_L: introduces too much room for mistakes in writing it and using it both
08:45 PM zhanx: i just spent a couple of hours in openscad, my brain is fried
08:45 PM Tom_L: heh
08:45 PM zhanx: but
08:45 PM Tom_L: the lead in lead out moves would be opposite as well
08:45 PM Tom_L: i don't like openscad
08:45 PM zhanx: my holder for this https://www.aliexpress.com/item/1-PC-60-125-250-500-1000-2000-5000ml-Pear-shaped-pyriform-Funnel-With-PTFE-Stopper/32875695735.html (250ml) is done
08:45 PM zhanx: well i have to wait and print it
08:46 PM Tom_L: you should find sw and export a stl model from it
08:46 PM Tom_L: whole lot easier to draw
08:47 PM zhanx: sw?
08:48 PM Tom_L: solidworks
08:48 PM zhanx: my flask for the 2L ones turn out perfect. Now I can clamp them over a bunsen burner
08:48 PM zhanx: solidworks is money
08:49 PM Tom_L: there's bound to be some free ones out there that export stl
08:49 PM zhanx: openscad does, and I am getting better at it
08:50 PM Tom_L: i just can't wrap my head around openscad
08:50 PM Tom_L: it's just wrong.
08:50 PM zhanx: tonight i did 4 parts, so getting faster etc
08:55 PM Tom_L: nice
08:55 PM zhanx: well 5 if you count modding my base part to be a funnel
08:58 PM Tom_L: lemme ask you something
08:58 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/ThreadMill.mcl
08:58 PM zhanx: k
08:59 PM Tom_itx: to change from internal to external threads the 3 lines starting with #FINAL_HELIX_R
08:59 PM Tom_itx: if i just reverse those 2 major minor and the third line to: #FIRST_HELIX_CUT = (#FINAL_HELIX_R + (#FINAL_HELIX_R - #FIRST_HELIX_R)/2)
09:00 PM Tom_itx: wouldn't that work?
09:00 PM zhanx: that is what i was thinking you need to reverse it
09:00 PM Tom_itx: so whatever was a major turns to minor etc
09:01 PM Tom_itx: then add the cut instead of subtracting it for the first half cut
09:01 PM Tom_itx: i'll still have to fix the lead in lead out moves
09:02 PM rue_shop3: zhanx, you needed a 3d printer :)
09:02 PM zhanx: Tom_itx, I would try that and run it on the sim
09:02 PM zhanx: rue_shop3, I do, like a nice one or something
09:03 PM rue_shop3: no, I mean you needed one
09:03 PM rue_shop3: I wonder if you had had it a year earlier
09:03 PM Tom_L: oh and i'd have to add the threadmill R instead of subtracting it...
09:03 PM zhanx: rue_shop3, I would be farther along in the madness
09:04 PM rue_shop3: there are airfoils all over my printers
09:04 PM rue_shop3: one of the guys is getting into 3d printing
09:04 PM zhanx: airfoils as in flight?
09:04 PM rue_shop3: well, as in little race cars
09:05 PM zhanx: cool link me the file for my kids
09:05 PM rue_shop3: he seems to have designed...
09:05 PM rue_shop3: heh, he's on R3, or something
09:07 PM zhanx: i realize after you said that, if i increase the flask holder radius, I can make a bunch for an epic hotwheels track
09:08 PM rue_shop3: rofl
09:08 PM zhanx: one of my bases I made, one of those, a stick and paper. custom tracks for the kids
09:08 PM rue_shop3: http://ruemohr.org/%7Eircjunk/not_public_dont_open/finr3-s.stl
09:08 PM rue_shop3: http://ruemohr.org/%7Eircjunk/not_public_dont_open/topfin.stl
09:09 PM rue_shop3: it looks like they go togethor or something
09:09 PM zhanx: they do
09:10 PM rue_shop3: hows the new glass?
09:10 PM zhanx: nice
09:10 PM zhanx: its flat
09:10 PM * rue_shop3 nods
09:11 PM zhanx: next month or so I can replace the thread rod with proper rod so it doesn't wobble
09:30 PM Tom_L: ok i got the thread part
09:32 PM zhanx: nice
09:32 PM zhanx: here I was thinking i killed the chat
09:32 PM Tom_L: just reversed the first 2 lines
09:33 PM Tom_L: now for the lead in moves
09:33 PM zhanx: ok I need two threaded rods that aren't bent. 5/16-20x18"
09:35 PM rue_shop3: --
09:36 PM zhanx: ++
09:39 PM Tom_L: �//
09:40 PM zhanx: divide by zero error
10:22 PM rue_mohr: trying to keep track of whats 5 days old and whats the same topic from 5 days ago
10:26 PM Tom_L: external thread macro working now
