I think you can get a MasterCam post processor for Mach3/Tormach here.
So, bare with me, I used to be a mold maker but I have been out of the trade for 8 years so I am quite a bit rusty. Anyway, just got my machine set up, and I sketched up a quick design of the top of a piston with Mastercam V.9.0 to cut my first shape with my Tormach. I used a parallel rough surface program and it would stop cutting (just pause in place) at the same point every time I ran the program, then I did a parallel surface finish program and it would do the same thing, when it got to a certain point it would just stop.
I am using the MPFAN (I believe this is for Fanuc) post processor, is this part of the problem? I tried doing a copy/paste of the Mach3 post processor on Tormach's website and this did not work for me.
I rememember years ago when I was in the trade, using Dynapath controls we would have to buffer programs through the control if it ws too long, maybe this is the case? The first program was 80 kb and the second was 697 kb. Just looking for some assistance from those of you who are more experienced with this set up.
Any help would be greatly appreciated, thanks!
