From following bought plans on the 1st build, I was unsatisfied with alot of stuff. But I learned enough to know how things work, etc. So starting my 2nd build using my own design this time. I scrapped the DIY skateboard bearings, etc and using precision bearings. Also decided to use Baltic birch for the majority of the build
The Z axis will have fully supported 1/2" linear rods/bearings. The other axis will have (unsupported) 3/4" rods/bearings. Will be using 4x 269oz motors (2 for the X axis) on a 5 axis board (potential future 4th axis upgrade), 1/2" 10 acme threads with CNC Dumpster anti-backlash nuts. Will be roughly 16"x16"x9" cutting size.
I'm finished most of my Z axis. The Y axis bearings mounts is integrated into the Z axis to maximize strength and minimize wasted space and materials (ie: instead of "attach part A to part B", why not design both as one unit from the beginning). The carriage is about 10" wide to give you proportion ideas. Any feedback/comments welcome
