I have a new Citizen A220 and turned a .5 sphere. I would like to do some simple engraving on the sphere. I wrote a program in Mastercam, edited the posted program to work in the Citizen and made it into a subprogram. The program is somewhat long, not terribly, and I can't get it all to load into the control. Is there any way to run a program with any significate size on this machine?
