An arduino wired to step/dir/en will give basic cartesian movements like that, and everything will run on it, arduino comms goes directly to computer usb, so that part of whatever control you have now would become obsolete.
But on the other hand, depending on your existing setup, especially if you already use something like emc, you could review the EMC2 folder. This way you integrate the extruder dimension into your existing setup.
So you could either move everything onto an arduino, or else you need to extend the existing setup to integrate the extruder. Perhaps there is more than one way for the last part.
