So I am attempting to build a super rigid MPCNC that has 2" of Z movement. However, the calculator says that there is a minimum of 2.87". I see that a lot of people go with 2" of Z-axis movement for the rigidity and I am wondering how they are doing this.
Also, the cut calculator is giving me some puzzling numbers. I put in 2" as my Z-axis travel, but it states that I need to cut my Z-axis conduit legs to 1.5". It seems as if this length would not occupy the entire leg structure. Am I missing something (I probably am)?
