as of rn I cannot afford to buy s3d, any other alternatives? id prefer if you actually used them with your BB so i know it works, and linux friendly is a huge plus thanks in advance, Ariel
One alternative is Slic3r, second Cura. A third one is KISSlicer (latest version from here). Repetier is also there... Or MatterControl... S3D is currently the most used, some used Cura and Slic3r so there are no real published settings you can just install and it runs. For KISSlicer @orcinus published his settings somewhere here (don't find it atm). To start with another slicer you have to get in touch with it read the docs of how to configure for a printer and I recommend having a look at my S3D Profile Builder, there is a script folder with sequences for the start, end and tool change which shall give an impression of what should be done before and after a print.
I have a Slic3r profile for dual if you want to try it out. Have only tested printing using the T0_only settings, but i have added toolchange script for ram purge for dual printing. https://github.com/tohara/BigBox-Files/archive/master.zip
Download RapetierHost (it's FREE ! but they do ask for donation) and it will handle all your needs. Add the download of Slic3r and you can add more if you want.
Repetier host is pretty awful on Linux, or at least was at the point I gave up on it, mattercontrol worked well for me though.
