I used the pucketing dummy program and it starts where I wanted. Worked out great. Thank you. BTW tech support never got back to me yet...................

Thank you for your input. I will try with the pocketing dummy program when I get into work in the morning. High feed is an option, but the pocket depth is so deep that it doesnt help. Max rpm on my machine is 2500 rm. 50 taper boring mill. rough pluuging the pocket out 8 inchess deep with a .75 corner radius on the bottom x's 2.25 wide. Most of my material is out of there already from drilling with an inch and a half inserted drill. and the walls are semi finish about 4 inches deep. Ok heres a rough dimenson of my slot. 8 inches deep x's 2.25 wide x's .75 corner radius so that gives me a bout a .75 flat area on the bottom and its about 18 inches long. Due to these dimension I am down to an 1.25 Sandvik plunge mill to rough out the rest of the material.Now finishing will be another night mare, but I am sure I will just crawl through there with a long extension inserted cutter. Start with a short one and work my way up until I get to full depth.

Thank you for your advise. I've tried that too. I've tried many things but to no success. It still wants to start where it wants. Some times mastercam wont give you the toolpath you want because the part geometry is just odd. I am just so frustrated with the soft ware now. Also the owner of my company is too. We've been using mastercam since version 5, and sometimes just for the software to do the simplest things, it wont do it. It's like screw you I dont want to do it. I want to be able to use these supposively awesome tools and tool paths, but I cant. It's been almost a week since I've contacted tech support. Still waiting for an answer and some help. But the time they figured it out I've probably figured out a different way to finish the part and shipped it already.

Has anyone had any success with this tool path? First time I have using it and it seems that it does not give me many options of how to control where I want to start and stop. I am trying to plunge a slot 8 inches deep by 2.25 inches wide with a .75 corner radius at the bottom. Many tool techs suggest plunging down and feeding away from the wall, and not going down to the same depth each time you step over. Only options I see is helix and peck. I am using x6 (mu something version). The material is A514 tool steel with flame cuts on the out side profile.
