Might be adding a small sub spindle mounted right next to my main spindle at 90 degrees so I can machine into the face of parts on 4th axis. Getting that spindle to operate at the correct time will be a whole different can of worms, but for now im wondering about swapping my x and z axis so I can still generate code in fusion cam for machining on the face of 4th axis parts with the horizontal sub spindle. My x axis has B slaved to it for dual motor, dual ballscrew. If I use the standard swap axis call for x and z, is slave B going to follow as it should? Or is this going to complicate things?
