Hey guys just wanted to thank you for the help. I tried a bunch of different approaches before going back to the original 'jumpy' toolpath and now I think it will work ok. Funny how taking a couple days off of a project can clear your mind and get you re engaged!

G94 didn't make a difference and i double checked to make sure a and b are unlocked and they are.

i added the file to the ftp site called "5ax box". it's tool path 33 that i'm working on. some things like the step over are adjusted high just for verify speed.

hey guys, first post here and i'm hoping you can help me out. i'm new to 5axis programming and so far i've been able to eventually figure out a solution to my problems until now. i have a 2011 haas vm2 with a tr160 and the part i'm trying to machine is basicly a large hollow box. i want to use a shorter length ball mill in an extended holder and surface the inside rather than a 5inch .375 endmill to get way down inside the part. after quite a bit of messing around i ended up with a toolpath that looks good in verify/machine simulation but when i post to the machine it jerks all over the place. it seems to travel the right path just not in a smooth motion. i'm trying to narrow down where my problem lies (cam/machine settings). heres a small portion of the code i'm getting, maybe you guys can point me in the right direction. thanks in advance!
