I have a high school customer that has 3 novaturn lathes that we sold about 10 years ago. They have smartstep 3 boards in them and are still using the dos flstep interface. Being a high school they have lost all of the original software disks. I only had 1 version of software archived (not sure what version it was, maybe 1.77) and it looks like the axis are moving farther than programmed (eg program says move z-3 inches looks like it moves about 4 or 5) Couldn't find a ruler in the school so not sure on exact distances. This is what's in the flstep.opt file:

I have uploaded our current copy of FLSTEP here:
https://www.denfordata.com/downloads/dos/flstep.zip
- sorry we don't know much about it, but maybe someone else on the forum could help ?
Looking at the new (ie, latest) opt file, I see an additional option:
rem mint_mfact 200
Even though it is remarked out, my guess is that it could be used to set the number of steps per mm - novaturns are normally either 160 steps per mm or 200 which is close to your 4inch to 3inch movement ratio
Although I could be completely wrong
