I like it I like it. I have a question for you.

I bought an Ebay linear actuator with a precision ball screw and bearings, and a linear guide all nicely mounted on an aluminum frame. I failed, however, to ask about weight. Its gotta weigh 80 lbs.

Will the gantry and YZ car handle this sort of weight? Am I going to create inertia problems with this much mass?

ALso, the Z axis block is cast iron- really heavy. How best to balance out that weight? Gas shock? Springs? New aluminum block?

I have a PR machine, and I've never been very happy with the PR Z axis. I'd really like to use this Ebay actuator, but if its too heavy, I'll resell it and call it a learning experience.
