I have a monoprice maker select (made by wanhao an i3v2)

I am using a flexion extruder. the thing is absolutely amazing but SUCH a pita to tune apparently because you have to balance on a thing wire between stalling the stepper and not gripping tight enough on the filament.

SO I want to take the much easier path at this point and simply get a higher torque stepper.

but what will WORK with the i3v2? preferably something amazon since I have prime.

how much torque does the v2 stepper have ?

There should be a brand and model number printed on the back or bottom of the stepper. You can look up the form factor and torque on the manufacturers website (just type the model in Google)
