None of that should matter should it? I am using a pendant to move the lathe 1" and then adjusting the software "steps per" to match. My problem is that changes to "steps per" are not making any difference in the outcome. For instance the last adjustment, when 1" movement showed as being 10" on the DRO I then needed to divide the steps per by 10. That brought the steps per to 100. After making the change to steps per, I run the same test and the DRO still said 10"
