I haven't ever tried a 34, but I understand that they have the same problem. I think you need to look at your critical rpm and and make a decision on torque at that rpm, at your voltage. My lathe has a 3-stack 23 on the Z with a 3:1 reduction and a 5mm pitch screw. The X has a 2-stack 1:1 and a 2.5mm screw. The X is faster, and stalls less. But then the X has an easier life.. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
