The purpose of the two motors is to remove backlash in the system. You'd need a control that has that capability.
I have a rack and pinion setup, I was wanting to know if making it a double pinion design is as easy as just adding a second pinion/motor/sled to mount on for going both directions?
Here it looks like nothing special they just added another full pinion set, is that all there is to it if you have a working single pinion/rack setup?

I'd be driving it with a stepper/marlin/arduino/ramps1.4
I'm not an engineer however I have another question would a gearbox that allows one motor to drive two or three pins be more effective than one pin since it makes more contact? Would there be any benefits in precision or backlash reduction?
So we'd have something similar to this driving on the rack
