engraving a large circle

[cherokeechief79]

im making a plaque and its got several large rings on the outside of the design.they are about 5.5 radius.im usind a pointy 82 deg engraving tool and would like to go about .06 .08 deep.i dont want to just plunge straight down and leave a witness mark.can i ramp down into this with a leadin that follows the arc?im pretty sure i can extend the start and end of the profile(although im not sure on a circle)

this is still mc 9

Can you do a contour, ramp, turn off cutter comp and have no lead in or out and a bit of overlap?

Morning Mark..

 

in your contour parameters... choose ramp... for your contour type..

try ramp motion by depth and put like a .5 in for your ramp depth and check make pass at final depth.
