2 Steppers For one Axis

[JasonCroyle]

Hi Everyone

Iam building a new Pen Plotter and to simplify things I would like to use two stepper motors for one of the axis rather then build some sort of mechanical linkage.

My biggest problem Iam running into is how to wire the two motors together Iam hoping someone here may have some options they might share with me. I was thinking of just wiring them in parallel but I dont think that will work I belive it would draw to much current. I also was thinking about using one of the other axis ports considering I have a fourth axis Iam not using but am not sure if there would be anyway of controlling both motors in the same axis with out having to modify the software somehow.

Well any help from anyone would be greatly appreciated. Would it be possible to run two X axis motors maybe by using the fourth axis Iam just not sure how to go about doing it. Again thank you for any help.

Thank You

Hi Again

I was just thinking would it be possible to through software just simple send the same data to two diffrent steppers. Such as simply config X Axis Stepper and Y Axis Stepper through Turbo CNC to take input from which ever I/O pin and simply do it that way. In that way both axis would recive the same info. If that sounds like it would work does anyone have Turbo CNC and will it allow you to configure one I/O pin to two diffrent steppers? Again thank you for any help you can provide.

Thank You

Hi,

I have used two drives and two steppers on a X axis which worked fine. All I did was wire both drives to the same pins on the parallel port. Only issue might be if your port does not supply enough current to two drives but could not say if that would be a problem for sure.
