In case you want to keep using the rail system (U2RS) and want to upgrade to the new + feeder I published a simple bracket.
Upgrading is pretty easy, specially when you reuse the feeder motor.
Get all parts for the feeder at your local distributor.
Your feeder motor needs to have the D-shaped axis to be able to reuse it.
- get the feeder parts at you local reseller.
- Print the bracket
- Mount the feeder (when you reuse it, you have to cut about 8mm off the axis off the old motor, or use a thicker mounting plate), you need 4x M3x10 to mount the motor
Upgrade the firmware to Tinker 16.03.1
