Ok I am doing a part and have generated the CAM but I am confused. I am milling a T shape. The long part of the T is .13 wide. so I figured a 1/8" endmill would work. Fusion fails to generate a toolpath. I get a big Yellow triangle but no reason why. If I go down to a 2.5MM endmill it will work. I have the tool plunging and not helix. I have messed around with the ramping and still no luck. So maybe some of you experts can explain to why? I was trying to mill a slot but using 2d Adaptive. The slot was .043 and I had to go to a 1/32 " endmil to get the path to generate. Then I tried the slot function and was able to go to .042 and get a toolpath. Just trying to understand this..

Thanks
