1. A method of additive manufacturing, comprising:
rotating, via at least one motor, at least one of two proximate hobs to receive and push therebetween a print material filament to be extruded from a print nozzle tip for the additive manufacturing;
adjusting a force adjustment on one of the two hobs to urge the force-receiving hob toward the other of the two hobs;
pulsing the force adjustment so as to remedy one of a clog or a slippage of the print material during the push.
