Hi all

I could do with some other peoples views please,

1/ on my "Z" axis I have 2 ways of mounting motor, one direct on top of the lead screw (12 x 3mm) and drving directly through a coupling PICTURE 1

and

2/ mounting up side down behind the "Z" and belt driving accross the top, PICTURE 2

I cant decide which is better, I have the plates cut for both ways, so thats not a problem. method 2, I will have to loose 10mm of travel for the bearing housing, I will still have 160mm (6"+) I dont have the belt pullys or the belt

What I would like to know is which is better and if metod 2 what belt ratio??
