i have a mcv 4020 okuma milling center with an osp p200m control and i need to sequentially engrave serial numbers on some four hundred pcs. our machine supplier said it could be done with a macro program and want 1500 bucks for the program as well as a software update for the control to handle scaling of the number letter combo. does anyone have a good example for this control? i found some fanuc examples on cnc zone, can i alter the fanuc code for the osp???
