You can use Mach2 and use the slaving option to link them in the software, or you can drive two drivers from the same step and direction pins. It's not a good idea to physically connect 2 motors together.

It not even a good idea to use 2 motors to drive the same axis. The motors, drivers are not matched and are at best loosely synchronized.

so how you deal with big Y axis arms ? that required 2 motor for X .
I see alotta big CNC using 2 X axis motors.

is there some kind of Syncronize stuff ?

Shopbot and many other commercial router manufacturers have been doing it for years.

Yes, and their stuff is not under $2K. You have to use the driver and software and feedback from the motor to synchronize the movement...it's not a trivial task. You can't just throw in a few Geckos connected to Mach2 and have a commercially viable product.

Shopbots prior to the new models introduced a few months ago had no feedback. As for Mach2 with slaved Geckos, plenty of people use it just fine with no problems.
