Try entering the value with out a operator key first e.g. 1.125 no plus or minus sign.

Have a look at the format strings in each screen set using screen4, one will not have the + signs in the string.

If you click on any DRO and press the +, -, / or * key, you can do calculation on the current value.

My guess is its not on steppers and its not home made 

A fast spindle on a rigid machine cutting aluminium with carbide tooling.

If you want impressive machining look at these : http://www.youtube.com/results?search_type=search_playlists&search_query=matsuura+5+axis&uni=1

If I were doing multi pockets then a calculated G52 local shift would be my method.

General Mach Discussion / Re: Pocketing and Island avoidance issue, need help

« on: April 22, 2009, 03:23:38 AM »

If you are +-.003 over 5" then over the 24" travel of the machine you can be .040" out and dimensions will not be consistent.  It must be and can be spot on.

Try putting the calculated figures in again.  When you change a steps per setting you should restart Mach3 and then do your checks, if you are not doing that that may be why you are getting strange results.
