i have artcam pro and am very new to this. i am cutting a ,080 slot .090 deep in expanded foam pvc i use 100" feed rate and it cuts good but where the tool enters and exits there is an incomplete section of about 3/8 of an inch. it looks like z axis is pulling out to early this happened in another very short section and tried slowing the feed rate to 30" feed rate and the z axis pulled out properly. i don't want to run that slow on the other as there is a lot to cut. can i overlap my start and end? so as to cut the gap i am getting.

2nd question can i cut two different cuts on the same vector. for instance one cut offset, and the other cut along the the vector, the cuts are different lengths.
