I see it is a Professional 6 controller. If you are looking to have to multiple wear comps for one tool there is a function on your Machine called Composite Tool Function. To make it active it is just a parameter that needs to flipped on and some set up in the tool data page . Once set up the program will look like below. Just make sure you set your H values the same for multiple offsets or it could result in a crash. You might have to play around with function since you are utilizing MAS so you are probably using FTN on the tool data page instead of PTN. Also do you always use H1 D1 (Tool Data Transfer)? Feel free to send me a personal message. OFFSET 1 DEFAULT WITHOUT M451 S1) M451S1 G0G90G54X0Y0B0.M03S500 G0G90G43H1Z25.0 G0Z0. G01X200.F1250. G00Z50. G91G30Z0 G00G90B90.
