	If we want more than 600 lb force with belts, we could use belts other than the tiny GT2 belts."		If we want more than 600 lb force with belts, we could use belts other than the tiny GT2 belts."

			*Thus it seems even a powered universal axis on both sides could do more than enough given that [https://www.youtube.com/watch?v=ycGDR752fT0 This] filament test used a max below 200lbs (~70-80kg so a 200 lbs limit is more than enough, 1/3 of this setup)

			*Marcin on the [[Universal Axis]] :
			"Universal axis does 50 lb precision force per 15 mm wide high precision GT2 belt strand with nema 23 motors. So in practice we can get up to 600 lb of precision drive force if we use 2-sided drive (like Y1 + Y2), 2 motors per axis, 3 belts per axis. Screws can be used for higher force.

			If we want more than 600 lb force with belts, we could use belts other than the tiny GT2 belts."

*Part of the [[Open Source Laboratory Construction Set]]
*An Open Source "Universal Tester"
*Used to measure the [[Compressive Strength]] , [[Shear Strength]] , and [[Tensile Strength]] of any material made into the standard shape (usually a bar or hook
*Uses load cells, but the early versions could use [[Hook Style Scale]]s
*Is almost essential if we start making any materials to provide hard, consistent evidence of material properties, especially for metals, and plastics
*Can also be used to test various weld techniques (On a purpose built small destructive test sample however for proof of concept, it doesn't replace a [[X-Ray Based Weld Inspection Device]]
