Are you stepper inside a heated chamber?

A motor current rating of 2.4A is way too high for any sort of plug-in driver.

I thought I could run them with much lower current, since their torque rating is pretty high. 2A+ is no problem for RAPS128 drivers.
Now I'm hesitating buying 1.2 or 1.7A 0.9° steppers. Will they be good enough for extruder direct drive?

If I had to choose between a 40mm and 48mm long 0.9° stepper, both rated 1.7A, I should choose the shorter one because of the lower inertia?
