6/16/18
i have uploaded a new body and tensioner that works much better when needing to release filament as well as improving grip on flex materials. the tensioner along with the nut and threaded bolt have moved

i had to design a completely new housing in order to get the gear to work properly, it is still in need of updating to accommodate the second extruder when it is offered. it uses all of the existing M3 screws that mount the motor to the housing and to the carriage assembly in the same locations and the tension spring. in addition you will need 1 M4 nut, 1 M4x60mm bolt and 1 3mmx26mm steel pin.

i have added a V2 that has some tweaks to allow the tensioner to work and mounting screws to snug up when tight

please give me feedback so i can make it better then it is.

i added a new version of both the tensioner and cap which should help with slippage. it is in testing now

wanted to improve the Extruder R2 drive gear with the bondtech drive gear
