	Minimum acceptable pull force is 5 lb. Tighten extruder spring if this is not the case. Motor skipping indicates limit. If motor skips before 5 lb, verify that motor current is sufficient.		Minimum acceptable pull force is 5 lb. Tighten extruder spring if this is not the case. Make sure 33 mm long spring is used. Motor skipping indicates limit. If motor skips before 5 lb, verify that motor current is sufficient. Sometimes filament slipping is a limit, in which case the extruder spring force must be improved. Slight optimization needed there to add 1-2 mm of spring tension by making extruder spring mounting holes more shallow, or design them differently so spring is easier to remove.

	*May 22, 2020 - 5.5 lb pull force. Notice small 3 mm spacer inside the extruder spring hole.		*May 22, 2020 - 5.5 lb pull force. Notice small 3 mm spacer inside the extruder spring hole.
