From Ray Log

Update: mostly good news but one piece of bad. I am afraid that installing Lulzbot Cura 21.04 or 21.08 for Linux is impossible at this time. FAME 3D, the new owners of the Lulzbot brand, have no interest in supporting Linux, and Luzbot Cura Linux installer scripts, Debian packages, etc. still point directly to a website of the old owners, Aleph Objects, whose website is now defunct. So the Lulzbot Linux installers of the past are no longer available online despite random forum posts to the contrary.

With that out of the way can we still go forward with this? All other software is in place but that and as we've discussed there are many alternatives these days and many are included.

As far as putting up OSE Linux 2.0 on your servers once it is done, of course! Do I have the authority to upload that myself and can it handle a 4.5GB upload? I would also like to make it available as a torrent to reduce bandwidth load on the OSE servers.

Lastly about that 4.5GB...I know you wanted to keep it under 4GB, but this is already highly compressed (xz compression) so getting the compressed image to something like 3.9GB would require removing several GB worth of apps, language packs, etc. and that would make me sad. Can we up the requirement to either a 8GB USB/SD drive or a blank DVD and DVD writer?

I'm happy to report OSE Community Member William Neal successfully got RC4 up and running and is happy with the results. Also, OSE Community Member Tauat Pixel generously provided a bunch of Creative-Commons-licensed photos to me that I have curated and transformed into a set of 12 custom desktop backgrounds all with the OSE logo in the corner!

If this is all good, we will have something ready for August 1 for sure.

Thanks so much for this opportunity.

I just added https://wiki.opensourceecology.org/wiki/Using_Inkscape_to_Generate_Gcode#Support as another option for generating gcode from Inkscape. It worked for me. I have not tested Big Blue Saw. Both are in the comment at the OSE Linux software spreadsheet. At this point, I think Gcode Plot is preferred over Big Blue Saw, but try to install both extensions if possible. - mj
