Hi William,

The MK8 extruders are ungeared so they may not be able to output the torque required to overcome the back pressure of our nozzles. [br]

[br]

The recommended extruder for the Chimera+ is the titan extruder (https://e3d-online.com/titan-extruder) with a compact but powerful motor (https://e3d-online.com/motors-compact-but-powerful-motor. [br]

[br]

Other than that you may be able to increase the torque output of the MK8 extruder by usign a geared stepper motor such as this one: https://e3d-online.com/motors-geared-stepper-motor
