Sounds like you need a stepper driver that can handle over 1.7A at 12-36V.

The Pololu A4988 stepper motor driver is popular:

"It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling)."

Sounds like those will need heat sinks and a cooling fan.

To get slightly higher power handling you can use the Pololu DRV8825 stepper motor driver:

"It operates from 8.2 V to 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling)."

Sounds like those will still need heat sinks and/or a cooling fan.
