pulley ratios on 3 pulley axis

[John S]

Jesus H Christ this is like pulling teeth, we have all the details including what you had for dinner but not what was asked.

HOW MANY STEPS PER ARE YOU SET TO ?

Using EMC2, not mach3 so you don't set the steps per directly... you enter motor steps per rev (so 200 is correct), microsepping (so 16 in this case), pulley ratio (4.5 as discussed) and leadscrew pitch (120mm).

It looks like at the moment you have the leadscrew pitch set to 100mm not 120mm .... so either change that or put the ratio to 5.4 and it'll be fine.
