OK, My 1st program.
In regards to making arcs, is I and J incremental or absolute in Mach3? What if I am in G90 mode?
I plan on cutting a path by programming the points of the outline and using both G41 and G42. You see, I have a .375" cutter and I am going to for the first pass, G41 and use a P variable of .375 ( .750" diameter cutter), get to the end of the pass and then switch to G42 w/ a P of .3125, go back up that path but in reverse. I want to go back and forth getting closer each time to the final dimension until I use a final P of .1854 as this whole operation has been a roughing cut in 4140 PH. I will not be making any tool changes so I won't be using D variables. From what I understand, I don't need any lead in moves when hitting the end of the path and changing between G41 and G42. My question is this, will I need to include lead in moves because I am changing my P values?
