Just worked up a very simple coaster project: Let's make a coaster — try that?
If you want to do a V-carve (or anything else for that matter), you have to follow through from step-to-step, and define everything for the software and the machine — it can’t guess, and using the wrong defaults is worse than a guess.
If you don’t have a #301, let us know what you do have and we’ll work with you to get it set up so that you can do this.
