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, the axis of the feeder motor has to stick 10mm out of the small gear)
Upgrade the firmware to Tinker 16.03.1
Change the e steps from E282 to E564, with the fantastic @tinkergnome firmware you do this in preferences/motion settings.
