dotSCAD VS Original-Prusa-i3

If you're looking for examples of high quality openscad code, dotSCAD is pretty cool. nophead (old school reprap person and one of the openscad developers) has a parts library that I think is high quality.

Justin Lin passed away due to illness in 2022 at the age of 48.[0]

On December 22, 2022 OpenSCAD posted:

> Today's advent calendar door is a sad one. We'd like to commemorate Justin Lin, who passed away a while ago. In the OpenSCAD community he is best known for his #dotSCAD library. His designs always brought joy and amazement. Thank you, we will miss you.[1,2]

On October 11, 2022 dotSCAD v3.3 released — it was the last commit by JustinSDK on GitHub.[3]

https://github.com/JustinSDK/dotSCAD - as far as I can tell this is widely used

I synced your repo: https://github.com/JustinSDK/dotSCAD

// require https://github.com/JustinSDK/dotSCAD use use use n = 5; radius = 10; thickness = 1; geom = geom_icosahedron(radius); points = geom[0]; faces = geom[1]; for(f = faces) { triangle = [for(i = f) points[i]]; // subdivide the triangle triangles = tri_subdivide(triangle, n); points1 = [ for(t = triangles, p = t) let(unit_vector = p / norm(p)) unit_vector * radius ]; points2 = [ for(t = triangles, p = t) let(unit_vector = p / norm(p)) unit_vector * (radius - thickness) ]; ff = [for(i = [0:3:len(points1) - 3]) [i, i + 1, i + 2]]; color(rands(0, 1, 3)) sf_solidifyT(points1, points2, ff); }

If you are into OpenSCAD, grab this chap's work - https://github.com/JustinSDK/dotSCAD/tree/master/src and use his modules, they are rather good.

// use // a shape function from https://github.com/JustinSDK/dotSCAD // sq_outer = shape_square(size = 50, corner_r = 5); sq_outer = [[20, -25], [21.9471, -24.6053], [23.5868, -23.4835], [24.6602, -21.8118], [25, -20], [25, 20], [24.6053, 21.9471], [23.4835, 23.5868], [21.8118, 24.6602], [20, 25], [-20, 25], [-21.8118, 24.6602], [-23.4835, 23.5868], [-24.6053, 21.9471], [-25, 20], [-25, -20], [-24.6602, -21.8118], [-23.5868, -23.4835], [-21.9471, -24.6053], [-20, -25]]; // sq_inner = shape_square(size = 30, corner_r = 3); sq_inner = [[12, -15], [13.8551, -14.3577], [14.9158, -12.7057], [15, -12], [15, 12], [14.3577, 13.8551], [12.7057, 14.9158], [12, 15], [-12, 15], [-12.7057, 14.9158], [-14.3577, 13.8551], [-15, 12], [-15, -12], [-14.9158, -12.7057], [-13.8551, -14.3577], [-12, -15]]; polygon( points = concat(sq_outer, sq_inner), paths = [ [each [0:len(sq_outer) - 1]], [each [len(sq_outer):len(sq_outer)+ len(sq_inner) - 1]] ] );

path_extrude from https://github.com/JustinSDK/dotSCAD library. This kinda works.

I've been effective with OpenSCAD and FreeCAD.

OpenSCAD is good for enclosures: https://github.com/sbambach/MarksEnclosureHelper

Don't think of it as a programming language; that will hurt you. Think of it as a specification language. That helped me.

Being the printer already assembled and working, I am looking at pg. 12 of the printer manual downloadable from prusa3d.com, chapter 6.3.1 Calibration flow and wizard, showing two different scenario... one for kit and one for assembled printers. Am I correct assuming I can just go through the latter? Also it's not very clear to me if that's the process I have to go through each time I turn the machine on, before attempting any print.

TLDR: replace the adapter-printer if it's worn.

They’re usually bought at https://prusa3d.com

On top of that, people simply don't know what they're doing. For example, the Prusa MK3S+ STL files are licensed under GPLv2, which does not make sense because there is no source (the source files are GPLv3 for some reason). But if you look at the remixes, the majority are licensed under some Creative Commons license end even the Public Domain. All those remixes are mis-licensed because only the GPL is compatible with the GPL.

you are right, but many people have asked for this.... reddit, github.. even on prusa3d.com but they dont care...

The BOM (of sorts) of the MK3S exists here.

No corresponding source for the parts is available? I don't seen an MK4 branch in there, unless they ditched openscad entirely (even then at least STEP files should be provided if it's still Open Hardware).
