My router has 4 stepper drivers running from a 3 axis board. My "Y" axis has two steppers, one on each side of the machine. Vortech sells a rotary for this, but they say I have to unplug the "X" axis to use it. My question is If I replaced the existing breakout board & drivers with a G540, can I run another G250 running in parrellel like I have now & still have the 4th axis to have its own port?
With that said, I do have axis to a G100. Would this be a better option?
