Hello,
I am looking for a step motor driver which could support The full step of the stepper motor is 3600 or 360 steps per revolution.
Step angle = 360 degrees / no of steps.
Step angle = 360 / 3600= 0.1 degrees.
Please suggest best driver for this

Matt,
Thanks,
Nareshreddy,
First find a motor can have enough torque to support your load or system. The motor could have 1.8 degree / full step.
If a mechanical gear can give more than 1/18 ratio, you may get 0.1 degrees.
Another idea is: use micro-stepping to get a higher resolution. "Microstepping control can divide a full step by as much as 256 times, producing a step angle as small as 0.007 degrees (51,200 steps per revolution) when the full step angle is 1.8 degrees. This significantly increases resolution (the smallest increment the motor can move). But with increased resolution comes decreased torque production per incremental step, which can degrade the motor’s accuracy if the incremental torque is insufficient to overcome the load and motor inertia." (Reference link: When should you use microstepping control for stepper motors? (linearmotiontips.com)
Another article gives the incremental torque table which can shows the load torque can affect the motor's accuracy. (Microstepping myths | Machine Design)
