Anyone using Mastercam ( lathe) to program Fanuc OT model B controller ? Machine requires a secondary tool change position at a given distance from z zero. This controller does not have geometric offsets. So I am between a rock and a hard spot. I do not know how to do this. Mastercam rep. says I will need to purchase a customized post processor. I can not believe I am the only one using this type of machine. (Takisawa TX-2 / Fanuc OT model B controller). Any help would be appreciated.ed help.
