As I was troubleshooting my build, to eliminate the possibility that the feet were the problem, I mounted all parts on a pair of 2020 aluminum extrusions and created spacers to keep the extrusions at the proper distance apart. I'll post a pic later. I'm attaching an STL of the spacer. Use either M4x8 or M3x8 bolts and T-nuts.
