• JellyBOXes exists in many variants. Some have cold bed, some have the heated bed, some have one filament fan, some have two.

It is essential that you select the right firmware for your JellyBOX depending on your specific configuration.

Firmware: JB-Marlin-2.0-RC3.2
(NEWEST for JellyBOX original)

released on February 10, 2018

This is a cosmetic upgrade.

The configuration for heated bed with one green probe erroneously states that it’s for cold bed.

The hex files have been regenerated, and read as 2.0-RC3.2
They are functionally the same as 2.0-RC3.1

Firmware: JB-Marlin-2.0-RC3.1

released on Jan 17, 2018

This is a cosmetic update.

Thanks to @pzaremba and his voltage regulator related troubleshooting trouble on the IMADE3D forum, we discovered that when you upgrade to jb-marlin-2.0-RC3, your JellyBOX will still incorrectly report it runs 2.0-RC2.

This made it very difficult to tell which version your JellyBOX is running, whether RC2 or RC3.

2.0-R3.1 fixes this bug. In all other aspects, this release is identical to RC3.
