I am very new and trying to complete my first try. I setup the machine as stated and zeroed X, Y & Z. X & Y work fine Z seems to keep cutting at least 5 mm to deep. I assume it is with the inital setup but before I dig into my bed anymore can some tell me if they have experienced this before?
If you continue to have difficulties, upload the .c2d file and let us know step-by-step how you are securing your stock and setting zero relative to it and managing all tool changes and upload a photo showing the machine at the zero position (or a specified offset from that position) and screengrabs showing what Carbide Motion shows for Position and Machine Position (click to toggle those twain).
