I don't see the point of wanting a round number. As soon as you've entered it into mach3/EMC you won't need to know about it at all. I've forgotten what the value is per step on mine....

I had decided that for the way i wanted to position the steppers that belts and pulleys was the way to go and at a 2.5:1 ratio i would get that round '1' it was not a requirement i could have even gone 1:1 and still can ill just swap out the pulleys and belts if need be and i will probably forget about it as you have.

The little ratio and ballscrew tutorial I wrote down in the middle of the post was perhaps to make things easier for some people to understand as it was a source of many questions from me when i did the other conversion. Using round numbers just made it easier in my mind to see what was going on thats all..

As fragger said, you will almost certainly be using 1/4 or 1/8 micro-stepping anyway which effectively changes the value but doesn't really gain accuracy..

Shouted! :lol:

on another note what do you think of the idea of a counter balance on the Z... please dont shout your reply its only a question...:heehee:
