The casting table is a tool. It's a tool for pouring liquids such that when they cure their top and bottom surfaces will be parallel. For this tool to function it has to be level. If it's not, the bottom surface will conform to the table while gravity pulls the top surface level. Once cured, the part will be skewed and possibly useless.This table is like a square. An 89.5° "square" is worse than no square at all. Or the planer. The planer only works if the cutter bar is absolutely parallel to the bed. If one end was even a 1/16" higher than the other, the woodshop would revolt.
The last time someone moved this table, and I spent 20 minutes crawling on the floor releveling it in place. I check it for level about once a week. You won't use one of the MMX's squares as a pry bar. Please treat the casting table like that
