It's been a while but I finally have some updates. I've started a wiki page which I'm updating slowly but steadily towards a nice detailed build instruction manual. At the same time I'm recording a video log of the build process of Rosalind #2 which is on PeerTube and soon on YouTube.by qwazix - CoreXY Machines
Re: no attribute rc_filename - 5 years ago
It seems that proterface fails to create its configuration file. It does create the directory though so a simple touch ~/.config/Printrun/pronsolerc is enough to fix that issueby qwazix - Printrun/Pronterface

I just installed an E3d chimera on the rosalind and designed a cooling solution (repository push coming soon). Changes are live. Here are two crude videos of the machine in action. I've decided to stop improving this particular instance and focus on making the design truly reproducible. To that end I will start on a new one and document the process step by step.by qwazix - CoreXY Machines

Yay! Many thanks. This will probably get to be the default extruder for rosalind. First step is to print one though. QuoteMKSA As someone proposed it somewhere, use a Bowden for the support filament and a direct extruder fro the "build". This is not a bad idea. I'll have to see if it fits with the e3d chimera.by qwazix - CoreXY Machines

The extruder carriage is modular and I will do what you suggest as an option, later on. For now, priority is to make it reliably print with two nozzles (thus bowden) because I desperately want to print buildings (which are unprintable without soluble support material, due to overhangs). I would very much like to use something like titan but I want to build a fully open source machine and while tby qwazix - CoreXY Machines

Thanks, I use the ungeared design on my old Mendel (and the new machine) with ABS and PETG successfully for a while now but I never did go over ~30mm/s printing speed because the old printer couldn't cope with higher speeds anyway (I assume it's not rigid enough) and the print quality suffers. Rosalind seems to be able to handle the speed much better but when I do set it to ~60 there's obviousby qwazix - CoreXY Machines
Re: Announcing Rosalind, a parametric CoreXY 3D printer designed in OpenSCAD and licensed under the GPL - 5 years ago
The version I published above had issues with backlash on the x-carriage. The aluminum rods/bronze bushings combination had issues as the aluminum rods where not exactly ⌀10mm and I didn't want to do any hacks to fix it so I decided to re-design the extruder carriage. The next version didn't have bronze bushings, it was one piece and the plastic was sliding directly on the aluminum rods, with soby qwazix - CoreXY Machines
Announcing Rosalind, a parametric CoreXY 3D printer designed in OpenSCAD and licensed under the GPL - 5 years ago
Hi all, I'm new here and I hope I'm posting in the right forum. I just completed a first working prototype of rosalind, a CoreXY printer. The code is still a mess, but in the spirit of "release early, release often", I decided to not wait anymore. Rosalind designed in OpenSCAD with the exception of the print fan funnel, which I had designed in blender for my previous printer and didn't re-do. Mby qwazix - CoreXY Machines
