In my experience with 80/20, the "L" shaped brackets are pretty flimsy. If you have problems with them , and / or have the means to, I would swap those brackets out for the gussett style connectors. A 30 series two unit gusset connector from 80/20 is part number 4338 N. They run at about $8.95 a piece, as compared to your "L" shape ones at $6.55 (Part #4304 N), but even if you only put one or two at each corner you will notice a HUGE difference. I can bend the "L" brackets by hand. Gussets, not so much.
Touching on the connectors though, you may want to slip a t-nut or two into the legs now, and brace the bottom of the legs, even if only with temporary pine 2x4s and a long bolt to the t-nuts. Once weight starts getting added to your assembly, those legs will start flexing more and more. It'll be much easier to do temporary braces now and put in t-nuts for future permanent bracing before you get all the weight of the machine on it.
Looking forward to seeing it come together!
