hi, i have this control board running(picture attached), i tried to wire another stepper to c axis and give it some gcode with 4th axis generated with rhinocam.
now the new stepper not act like a 4th axis but move together with y axis, so i assume they made that slot for machines which need double y axis motors. but thinking maybe it's from firmware or maybe it's gcode.
so wanted to ask, if i upgrade firmware is it possible to use that c axis as 4th axis?
if not, a 3 axis lathe still will be useful for me, what is the best way to use x, z and lathe axis and easily switch back to x, y, z axis?
gcode is here also if you think it's faulty, it's just for simple cylinder:
0501 support 3 axis 3linkage , then suggest you take X axis as rotary ,
Next time ,suggest you choose DSP A18 ,it support 4 axis 4 linkage ,process cylinder wood or square wood.
