I have not seen anyone use 80/20's linear motion bearing for a CNC Router solution.
I saw in another thread the UHMW-PE has is spongy and has a high coeffieicent of expansion. Others said this was OK for routing wood and aluminum.
This seems like such an obvious solution to the CNC router platform there must be some drawbacks or everyone would us these supplies.
Is it cost?
Thanks,
