00:02 <t4nk_freenode> I designed mine using OpenSCAD

00:02 <t4nk_freenode> https://postimg.cc/gallery/vd0XTDk made some better bearings for it just a few days ago

00:03 <JakeSays> that's cool

00:04 <t4nk_freenode> do you have a 3d printer too?

00:04 <t4nk_freenode> it's rather handy if you want to build something

00:04 <JakeSays> i have two of 'em

00:05 <t4nk_freenode> ah, nice ;)

00:05 <JakeSays> well, three actually but one i never finished building

00:09 <t4nk_freenode> why don't you use it as a basis for your cnc machine

00:11 <t4nk_freenode> if I make another machine, I'll be using bought parts though... decent rails, sturdy extrusions

00:13 <t4nk_freenode> more powerful motors

00:29 <JakeSays> t4nk_freenode: that's my plan

00:29 <JakeSays> well, for a pcb mill at least

00:32 <rapha> Jack225: played for a bit and got a hang of some of the numbers; printing one now to see how it'll fit https://gist.github.com/sixtyfive/3129397c7b09600d40f593d1a53310e1

00:33 <rapha> t4nk_freenode: we've got a laser cutting shop in town and they have crazy affordable prices for one-offs ... they do alu, steel, even titanium up to 6mm. perhaps you have one, too, and just don't know about them?

00:36 <t4nk_freenode> I have no interest for that at all

00:36 <InPhase> rapha: There are quite a lot of them around me.

00:37 <t4nk_freenode> I'm looking to make my own

00:37 <ccox_> quite a few here in SFBay as well

00:37 <InPhase> rapha: Although I'm near a city.

00:41 <rapha> t4nk_freenode: you do realize for it to be useful for steel, what ccox_ said is _very_ true?

00:42 <t4nk_freenode> I'm not after a laser cutter either ;)

00:43 <t4nk_freenode> but I would like to build a better cnc machine than I have now

00:43 <t4nk_freenode> just can't make up my mind on what to go for

00:44 <t4nk_freenode> about 1m² work area would be nice

00:47 <JakeSays> i wonder if there's any around here

00:47 <JakeSays> t4nk_freenode: i want a 3d printer that size

00:48 <t4nk_freenode> lol, so you can grow and shave 3 beards while the print runs ;)

00:48 <JakeSays> lol no it'll be a very fast printer

00:49 <t4nk_freenode> heh, what I'd _really_ like when it comes to 3d printing... is very high resolution

00:49 <t4nk_freenode> so I could make ic test sockets and such

00:49 <JakeSays> i make those now with .2mm nozzles

00:50 <t4nk_freenode> I experimented a bit when I just got my printer, got .1mm nozzles too

00:50 <JakeSays> well, not ic sockets but test rigs for boards

00:50 <t4nk_freenode> but I don't think it's quite possible

00:50 <t4nk_freenode> yeah

00:50 <t4nk_freenode> the resolution just isn't there

00:51 <JakeSays> what resolution do you need?

00:51 <rapha> t4nk_freenode: ic test sockets for what kind of ICs? because if they're DIP you might well get good enough resolution out of a commercial printer for home use.

00:51 <JakeSays> rapha: DIP's are easily doable on my ender3

00:51 <rapha> that's what i was thinking

00:52 <t4nk_freenode> https://postimg.cc/gallery/zWvb718 did this with my mill

00:52 <t4nk_freenode> how about a test socket for that?

00:52 <t4nk_freenode> ssop28, .65mm pitch

00:52 <JakeSays> you could do that

00:52 <t4nk_freenode> but .5mm pitch too

00:53 <rapha> perhaps with one of these printers which don't deposit material but cure it using UV light

00:53 <rapha> they're having good enough resolution to be used for dental prostheses

00:54 <t4nk_freenode> I think I'd have better luck trying to mill a test socket than to print one

00:54 <JakeSays> i even have some .65mm pogo pins

00:54 <t4nk_freenode> don't know about resin printers though, they might work

00:55 <JakeSays> i've printed parts with .5mm wire holes

00:56 <t4nk_freenode> the ic stuff was the first thing I tried when I got the printer, maybe I've advanced enough to try again

00:57 <JakeSays> ugh. i can't *stand* arduino ide's.

01:00 <JakeSays> they are the 2nd worse ide i've ever used

01:01 <rapha> just use platformio and whatever your fave editor is

01:02 <JakeSays> platformio is a mess

01:02 <JakeSays> i'm only using arduino's ide because there's a bug in qt creator i'm waiting to be fixed

01:04 <JakeSays> well, i shouldn't say platformio is a mess. it just didn't support any of the devices i was targeting

02:37 <t4nk_freenode> I might revisit the ic-socket idea

02:37 <t4nk_freenode> i dug up some pictures

02:38 <t4nk_freenode> it seems I didn't quite yet realise that you can orient the print in the opposite direction

02:55 <t4nk_freenode> heh.. there were a bunch of settings I missed I guess ;)

02:59 <t4nk_freenode> ..tomorrow.

03:39 <t4nk_freenode> (lol.. even my openscad design looks VEry strange :))) )

07:51 <Jack22575> rapha:  looks nice ..  another option would be to loft  it ..  as simplest with hull() and multiple thin 3D shapes at different height

07:53 <Jack22> the base looks  different in your code - than what i saw in the image .. just wondering

16:53 <peepsalot> sigh, i should have tested the windows builds before, but I think mimalloc is not being overridden/enabled correctly

17:06 <peepsalot> just noticed this in their CMakeLists https://github.com/microsoft/mimalloc/blob/master/CMakeLists.txt#L404-L406

17:06 <peepsalot> basically failing silently, not happy about that

17:50 <gbruno> [github] avivhu opened issue #4065 (Preview transparency issue: depends on order). https://github.com/openscad/openscad/issues/4065

18:10 <gbruno> [github] t-paul closed issue #4065 (Preview transparency issue: depends on order). https://github.com/openscad/openscad/issues/4065

18:35 <peepsalot> JakeSays: what's a code can?

18:36 <JakeSays> peepsalot: LOL code cad

18:38 <peepsalot> ok... I still don't know what it means to make a code cad convert

18:39 <peepsalot> convert what to what

18:39 <JakeSays> i've converted someone to use oscad

18:39 <peepsalot> ah

18:45 <Jack22> just made a teardrop module as the 45° seemed to radical  - i am no going with 70° as default .. if you like to test for feedback  model is https://www.prusaprinters.org/prints/122568-teardrop-test

18:48 <JakeSays> i used teardrops in my latest design

21:53 <MartynGriffin> Anyone online?

21:54 <teepee> maybe

21:55 <MartynGriffin> looking for some help in using openscad to modify an stl file.

22:00 <lf94> hi

22:06 <Jack22> so now i autocalc the angle via layer and nozzle  and and overlap

22:07 <Jack22> MartynGriffin:  import the file and what do you wanna change?

22:10 <MartynGriffin> the text in the surface is sunken into it. I need it to be raised above the surface.

22:12 <Jack22> you can use the difference of a cube and the object to get the text.. scale([1.1.2]).. then add it to the object

22:12 <InPhase> MartynGriffin: Intersection with a thin rectangle, use projection, difference that away from a square, then linear_extrude.

22:13 <MartynGriffin> you guys are too smart for me !!!

22:13 <Jack22> you move a cube so it is flush with the surface and covers the text.

22:13 <InPhase> Also, cheatsheet if any words we said are unfamiliar. https://openscad.org/cheatsheet/

22:14 <Jack22> Also maybe it is easier to create  new text   and extrude it

22:18 <InPhase> MartynGriffin: When I said "thin rectangle" I meant cube, using one dimension very small to only select out the surface edge with the text.

22:25 <MartynGriffin> reseting now.

22:30 <rapha> Jack22: https://i.imgur.com/0q3Zkpl.jpg ... fits like a glove! the secret sauce was to make the walls thin enough and just the right size at the base and the slight differences in shape even themselves out.

22:31 <rapha> now "just" need to finish up the motor adapter, install the power train, see if it fits length-wise and then decide for a color to print the final version in.

22:33 <Jack22> rapha:  happy to hear ..   be careful with pla as it can get hot around the motor

22:33 <rapha> Jack22: not my first rodeo ;)

22:33 <Jack22> you can also use it as a mold to laminate with gfk/cfk

22:35 <rapha> good lord, buy even more stuff? nah, the cowl is far enough away laterally and the adapter is too much aft of where it gets really hot. first time i made an adapter i put cardboard in between the motor and the adapter until it became clear not even that is necessary.

22:36 <rapha> things might change if i get into 3D flying more. but that's one of those bridges to cross once you get to it.

22:39 <rapha> actually, my old workplace throws huge amounts of cfk cloth cuttings out each week and they have everything that's needed. we've used 3d prints as molds before there and it does work beautifully. it's just that here it would be complete overkill. sure, the parts might end up a few grams heavier than the original ones were, but so i just move the battery back a millimeter, that's enough.

22:40 <rapha> https://www.instagram.com/p/CY6FLWPKqDz/ <== cfk cloth waste

22:41 <rapha> the stand here https://www.instagram.com/p/CIgjR-tLiP1/ is done using a mold made from a 3d print

22:50 <MartynGriffin> all done, worked like a charm. many thanks.

22:50 <Jack22> MartynGriffin:  fantastic

22:51 <Jack22> rapha: i assume the mold was printed in sections or was it a very big printer?

22:52 <Jack22> you can also fill the print with plaster and then heat vaccum form  sheet plastic around - like the orginal part was done

23:43 <rapha> in sections, Jack22 ... but i only did the prints (on my puny 15x23cm bed of what used to be an ender2 and is now, well, the very unique device i call a printer) and then my boss glued it together made a mold from it. he's good with these things and i don't care :)

23:44 <rapha> before that he used to have glass fiber molds made in hungary which always cost him half a fortune
