Z axis dual motors

Hi,
this is probably a dumb question.
How do you connect the motors in paralell?

Connect the wires of both the motors together.

Eg. If you have Green, Red, Blue, Black wires, then connect the corresponding Green, Red, Blue, Black wires from the other motor.

Depending on what type of control board you are using, sometimes there are two connector ports available for the Z stepper motors which is then driven off the one stepper driver.


On the RAMPS 1.4, there are two spots for the Z stepper motors to plug into, so you don't need to worry about connecting the wires together.

Thanks,
that's how I have them connected.
Is it possible to have them use separate drivers, is there any advantage in that.

I used a DRV8825 to drive two 42BYGHW811 stepper motors, with no issue. Yes the stepper motors were the wrong size for the application, but it worked.

My thoughts on running a driver for each motor would be that you need the full power of each motor for the application. The fact that the motors on the Z axis are on very little compared to the other axes you there's no real advantage of driving them separately.

Thanks for the info.
