I have a DXF file which is in inches, I use IMSI TurboCAD V8 which to my knowledge will not convert a drawing in inches to a drawing in MM.
I import the drawing into Vetric Cut2D in inch units, and again I do not believe that Cut2D can convert inches to MM.
I produce the required paths with Cut2D and export then to Mach3 in a txt file.
My problem is that Mach3 was set up in MM and if I change it to inches it screws up the Motor tuning. I have found that if you start Mach3 in mm mode then change it to inches it will work but you have to remember to shut it down in mm then change it back when you re start.
Is there a simple program that would convert the Gcode?
I could write on but why re invent the wheel if there is a good one out there.
