    Hello Sita how to calculate the formula answer voltage at the pot = .9 * (stepper current / 2). Neme 17 rated cuterrnt phase 2 Ames DC. Adds wiring

    That formula gives you the maximum. We typically try to run the steppers at much less than the maximum to minimize heat. 0.7V seems to be the sweet spot, with maximum torque with minimum heat.
