So I am going through the parts trying to build out a good quality mpcnc.
First bearingsHow important are the bearings? I was discussing the build with my brother in law who offered me skf bearings 608-2rh for an incredibly good price. It will of course be more expensive than cheap Chinese bearings but he is offering me enough to finish the build. So if I were to buy them would I see better prints over cheap Chinese?
Next the rails. I’ve read stainless steel is more Ridgid. I plane on doing a 2ft by 2ft build and I want to do aluminum milling. Is stainless steel going to make a drastic difference in the quality of the mill?
Sorry for the questions.. I am experienced in 3d printing but new to milling/cnc
