4th axis attempt

1st attempt at 4th axis, converted y to a in cam, drew rectangle on screen for visual cue, per instructions on cd, gives me my circumferance. toolpaths inside or right to the line, toolpath generated is bad 25ipm, a axis moves very slowly, 1 minute for 20 degrees of movement, when it makes a small cut then the y axis starts moving. i think my drawing or setup in cam may be wrong, when toolpath is generated the onscreen graphic in mach has a big loop in it that shouldnt be there. trying to attach drawing and mach graphic, unsure if i did it right,,,,

You must have a wrapping group. Are you setting your Z @ top of part? What version of Bobcad?

You need to tell Mach the diameter of your stock if you haven't.
