Motor stuttering with SimpleFOCShield + NEMA17

hardware support

Hi everyone,
I’m running a NEMA17 with a SimpleFOCShield v2.0.4 and an Arduino Uno, using FOC with inline current sensing. I’ve followed the basic examples, but the motor stutters at low speeds and doesn’t rotate smoothly under open loop. Power supply is 12V, current limit set to 1.2A.
Could this be a tuning issue or something with my sensing setup?

Thanks!

What mechanical speed are you stuttering at?
How many poles is the nema 17? This will tell us electrical speed.
