There is any feeder upgrade for UM2+?

[Alecsm 2]

I've just printed the Robert's feeder when i saw that i can use almost all the parts used on the original feeder. Uninstalled the original feeder and discovered that the main feeder roller different than the one presented in robert's install. instructions.

I've started to do this after several filament jam, while printing with flexible fil.

Any suggestions?

My feeder is only for the "original" UM2, it will not work with the UM2+. I've been thinking about making something similar for the UM2+ and I even started on it a few months back, but I haven't finished it (far from it).

but except the main metal roller, it is something different than the UM2?

Thanks

Yes, it also has another stepper motor with only 200 steps instead of 400 steps per revolution, and a small plastic gear pressed on the shaft.
