so what's the advantage of zeroing off the same side? I keep seeing people do this, but no one has explained why exactly. I have mine to zero off the top of each surface, is there an accuracy issue doing this?
C.J. It keeps the height reference consistent no matter what variations of thickness your stock has. Think about if you know with certainty the thickness of your stock and that it is precise and consistent (I.e. you’ve milled your stock to precise and accurate dimensions) then it’s no big deal But if your stock is not exactly as you describe it in the program, any variation in thickness from the real world to what you told the program will be an error in the thickness of your part Keeping the reference plane the same between the ops (top on first and that same plane after the flip means the bottom...) prevents any thickness errors arising from stock thickness
@@russellmiller2564 makes sense, it the stock is .05" taller you'd have .05" stock remaining in the middle of the carve. So the gcode just adjusts Z on the second side to match the final depth of the first?
