Hello everyone,
the story shortly, i have a machine that wont give a non-decimal steps per unit number, i wonder if mach3 keeps the ratio it gets from "axis calibration" with the decimal points  or if it will round it. (very important since the machine is very long)

for anyone interested in the long detailed story
 i am restoring and upgrading an old machine, the mechanical parts are fine, the electricals on the other hand were exploded to charcoal by the previous owners.
anyway i decided to fit the classic mach3 solution make it work as it should again.
But i need the machine in mm and the motor turns an 1:20.5 reduction gearbox, which provides motion to a 15 teeth cog which then transfers the motion to a .5in (12.7mm) pitch gear rack, which moves the piece, so in other words. so no way in this world this gives an non decimal steps per unit number.
if mach3 keeps the decimal points it is nice, if not it would be a huge cost of materials and days of work so if there is a way, i would love to avoid that (preferably without scalling anything, i wont be the only user of this machine so people most likely wont understand that and even i at some time may forget it).
the machine is a very weird special purpose built for cutting lines, X axis is ~20meters y and z are much smaller, and somehow in normal mm but if X is missing a bit of a pulse here and there in 20m distance it will be rather big


Thanks in advance
