You will need to make sure the power dissipated within the '317 is in the safe operating area -- Power dissipated is (Vin - Vout) * Ilim and becomes unmanagably large pretty quickly. You will certainly not be able to follow the guideline of "20x faceplate voltage" from geckodrive documentation. Iout = Iin, so you must also size your DC power supply larger than documents written for geckodrive or other switching stepper drivers.
Most stepper drivers use methods similar to a buck-mode switching regulator to give the desired amount of current in the motor windings--the motor winding itself is the inductor. This kind of driver has much lower power dissipation than a simple linear power supply.
