Here's a little update; I've had this THK kr33 actuator for a while and figured this would be the faster way to get up and running. I plan on making a new Z axis with square profile rails. The Z isn't mounted yet it's just on with one bolt, still need to drill and tap 4 holes. I have some THK SHS25 rails and bearing coming for the bottom axis. I will also change out the cross axis with either 20-25 profile rails. Here a few pics, I've figured out how to mount the ballscrews that came to short.
