I"m building a CNC router for woodworking, joinery and inlay. For the joinery work, dovetails of all kinds and mortise and tenon, the spindle will be oriented horizontally to the work table, so i can work on longer pieces, and simplify clamping. This means that if I draw a part the usual way in a CAD program, my z and Y axises are reversed. How do I deal with this? Is the easiest way to just manually swith the x's and Y's in the generated code (paying attention to the positive and negative issues I'd have with the Z axis)? Or is there an easier way that this absolute CNC neophyte is missing? Can I define two diffeeent machines in Mach3, one with spindle horizontal for the joinery work, one with vertical spindle for conventional work? I"ll be using MAch 3 with either sheetcam or Lazycam as CAM program. Thanks! See my work at www.alladd.com
