It will move from X x.x0000000000000 to X x.x0000000000000 The internal representation is double-precision floating point mm. Double-precision has at least 15 digits of decimal precision. https://en.wikipedia.org/wiki/Double-precision_floating-point_format If someone was to make a micro-machining system that needed better than femtometer precision they would have to "lie" to the system and set up the feedback and scaling so that a G-code command of X10 moved 10nanometers (or whatever) -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Transform Data into Opportunity.
