Thanks a lot.
About the leadscrews, the only place I can get the acme screws is McMaster -Carr. They’re kind of expensive. But, the nuts are the deal breaker. It’s close to $40 per nut (I don’t know if you’re familiar with USD; you can get about 100 M8 nuts for $5). I didn’t realize it was meant for a nut with around M8; I’ll probably just end up using regular old threaded rod for the z-axis.
Also, for the coach screws, how big is the hole, and is there room for a nut on the bottom?
Thanks!
