Confused about unit values and gear ratios

Thanks-
For a normal Alpha that primarily cuts plywood and melamine do you think it's better to go with the increased torque from 25 and 20/1's respectively? Cutting speed would still be limited by relatively small bit size (5mm and/or 1/4").

No. If you go with the 25T, pinion life is drastically increased. UV @ 2900 is more than enough for resolving detail & Z torque on just about anything a rack & pinion tool is capable of resolving.

Ok-I imagine you mean "decreased".
Same rack for both?

Hey Brady:
I've been having a very small undersizing issue and just did some checking into my control software and discovered that x and y unit values were set at 2482.8169 and set up told me I had a custom set-up. I can't for the life of me remember changing from default. Is it a safe assumption that the .0002 difference in what I had from the default settings would account for the parts being smaller? Or is it possible that they were changed to that to solve this issue earlier and it just didn't compensate enough?
