I am considering converting my Maslow over to a traditional rectangular coordinate cnc by ordering some linear bearings and rails. I would like to still use the chain motor and arduino from the maslow kit.

Does anyone know if it is possible to setup ground control as a rectangular system and have one motor drive the x and one drive the y?

No, the Maslow firmware will not support that (and Ground Control does not  
support other firmware)

What I would suggest is that you look at the grbl based fork of the firmware and  
see if you (or if you can find someone ) who can take the motor control of that  
fork and merge it into the stock grbl so that you can use the corexy kinematics  
mode of the stock grbl (see [corexy.com](http://corexy.com) for how that works), that will get you a  
much better machine than running the maslow firmware.
