Hi all,
I have a belt drive on my y axis.
Trying to calculate steps per mm.
Heres what i have got :-
Stepper motor with 18 tooth sprocket
driving a 45 tooth sprocket - which is fitted with a 20 tooth socket that drives the gantry along the belt.
So have started to try and work it out -
45/18 = 1:2.5 ratio
45/20 = 1:2.25 ratio
How do i realise a ratio i can use to calculate my steps per?
Done a little sketch (no laughing - i know, at least i didnt do it in crayon!) attached.
