which stepper motor driver is best for robotic arm?

[shangxin32]

I am building a robot arm am using TB6560and datasheet,with stepper motor 17HS3001-20B datasheet.

I have problem with the stop current setting i.e. when stop the driver tb6560 reduces current supplied to motor by 50%.

This reduces the holding torque in stop position(when no signal is given by arduino).

I want increase holding torque as well as torque in running condition .

Is there any setting in tb6560 to set dip s2 for required current setting ,because tb6560 board that is only have two option i.i 20 % and 50% of running current.

Should this problem can resolve with TB6560 or I change driver to TB6600 or any other driver like L298 ,A4998 or any better solution .

I am using 12/24 volt and max 3A.

THANKS
