Kit of parts needed to add a control interface and USB card reader to an Ultimaker Original, or repair/replace the Ulticontroller on an Ultimaker Original+. Avoids the need to keep the printer tethered to a computer during printing.
Requires a standard SD card reader attached to your computer to transfer files on to the SD card (files can still be printed directly over USB, but files cannot be transferred to the SD card that way).
To use this kit with a UMO+ you will need the longer ribbon cable available here.
