My understanding is for the RuiDa controller the Y axis output must be used for the Y axis and the rotary attachment.
My red and black laser came with a plug for the rotary axis prewired to a connector for a third motor driver. I added a driver for the rotary axis.
The Y axis motor is wired directly to the motor driver with no connector. I can not unplug the Y axis motor and plug in the rotary attachment unless I do it at the driver itself. Because the stepper motors require different currents and steps/rev setups the driver would have to be reconfigured each time I swap.
The idea is to leave the Y axis and the rotary axis motors wired to its own driver and switch the step and direction outputs from the RuiDa controller from one driver to the other via a DPDT relay and a switch on the front panel. Another method would be to wire the step and direction to both drivers and switch the motor power to the one you wanted to use. Switching the step and direction would keep the gantry locked in position however and switching the motor power off would allow the gantry to move.
This way I could jog the head over the rotary axis using the X-Y axis as normal, switch to rotary mode and burn the job using current position. When finished switch back to Y axis.
This way both drivers can stay configured for the motors they are driving and no plugs to switch.
Has anyone tried this or see a problem with doing this?
