Welp. Added an aluminum bed to my machine. Spent the last week a couple hours per night threading 324 5mm holes by hand. Ordered new limit switches today because my Z one is a little limp. Have new Gates belts to install next. Hoping to be back at it by next weekend. Special thanks to @JanVanderlinden for help with planning the bed.
Also, once I get running, I plan to mill some guide lines in the bed.
