Ultimaker 1.5.7 PCB driving multiple stepper motors

Recommended Posts

This is my first request for help from any forum, so please take it easy on me. 

I'm building a monster (5' X 5' X 5') printer after owning two kits.  Because of the weight of the gantry system, I'm engineering it to have high torque stepper motors on each corner so my Z-axis will have 4 steppers.  

To compensate for the current draw, I've purchased adapters to allow for multiple motor drivers off of the single Z port of my Ultimaker 1.5.7 PCB.  My thought is to parallel only the data signal off of the PCB and use a separate power supply that can handle the load to power the drivers.  If this will not work, will a current amplifier do the trick?

Attached are pictures of the drivers I have.

If this has already been addressed, please add the link to your reply.

If there is a more appropriate venue for what I need, please let me know.

Thanks

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
