Hi all, new member here from Central IL currently in the planning stages of a MPCNC. Prusa i3 MK3S+ is pending delivery this week and I’m excited to get it up and running and then printing parts for my MPCNC. Planning for a 24" x 24" working area.
My question is on tubing thickness, SS is not readily available in my area without a big MOQ. I can find 1" DOM 0.188" wall pretty reasonably and I realize that should improve stiffness (albeit pretty marginal), I’m curious if there is anything to be concerned of with the size of my machine and inertia of the additional mass swinging around on the gantry? Would I be better off using 0.125" wall on the Z axis only for the nut traps? Stay with 0.188" and modify the nut traps on the Z?
Thanks in advance for the assistance!
