I had a problem today when carving line work with a vbit.

A little background, I imported some .dwf line work I created in AutoCad. Brought into VCarve and created a single toolpath for all my linework(I was creating animal shapes on a wood board). The depth would change randomly from line to line, some lines are at the proper depth and others were at about half the depth.

This also happened randomly when I did some lettering. I created a word in VCarve, created a single toolpath and the word would start shallow and progressively get deeper. Really strange.

I'm using Mach3 and a Romaxx CNC.

I'm thinking about reinstalling Mach3 tomorrow, unless someone has some thoughts. I have a ton of work this weekend and need to solve this.
thanks!
