Hello, this is a 2003 vm25 with Milltronics Centurion 7 control, when I use the clear pocket for a slot and tell it to ramp for Z it does a helical circle at the Z depth of cut? and if I change the ramp angle it dont change, what am I doing wrong? also it does the helical circle on the edge of the slot and will leave a witness mark, sometimes I dont want to run a finish pass and just rough to size, is there a way to change this? thanks
