Does anyone know what causes this? I am cutting out necks for guitar and when nit goes to cut out the profile of the neck the first couple cits are smooth and in line with each other. Then about 1/4 of the way down it steps. Does it on both sides of the neck and only on the sides. Ive tried a couple different carves with different settings. I orginally followed Chris from Highline guitars settings for when he had a X Carve. The slowed the feedrate down from 100 in/min to 60 in/minute. No real change. All my carves stepped over at the exact same depth.
