			*Less design change is favorable for going with 4 motors - the main case being for stability (larger weight handling is also a plus but secondary)

			=Retraction Settings=
			*Had default at 2 mm at 40 mm/s retraction at 1.2 nozzle.
			*Increased to 4 mm - first clog ever. Reduced retraction to 3 mm

			=Z Motors=
			*Either more Z motors for better balance - or counterweight - are useful for handling the heavy weight of the bed. Motor skip upon going all the way to the top of bed in Z direction.
			*Z motors will provide better balance if there are 4 corners of them. This will stabilize print quality.
			*But also, another option is wider z parts. But this gets away from the natural modularity of the system.
			*Added cost of 2 motors is about $50 for 2 axes.
			*Added cost otherwise is a counterweight, which is lower cost.
