These are firmware packages that are no longer updated so we have released them for free. These are provided as-is with NO support included. See attached files to this article for all the discontinued packages.
While there will be no updates for these, if you do want technical support installing or configuring them we do offer a per-ticket support package. You can submit a ticket here if you want to get paid tech support: https://tickets.th3dstudio.com/tickets/create/step1
Do note that any "Melzi" boards also need to have a bootloader installed. You can see our guide on that here: https://bootloader.th3dstudio.com/
