Hi folks, I'm about to assemble the E3D Titan with the supplied E3D Slimline

Hi folks,
I’m about to assemble the E3D Titan with the supplied E3D Slimline motor.
In the datasheet for the motor, I found these values:

  • Rated voltage: 2.7V
  • Rated current: 1.4A / phase

I’m using TMC2100’s in spreadcycle mode.
What value for calculation for Vref do I need to use? Imax or Irms?
Thanks in advance.

i would run the motor at 1A and if it is skipping i would consider increasing it to 1.1A.

@Cristian_Nicola Thanks.
Do you mean 1A Irms or Imax?

0.71A rms, 1A Imax. - 1V on the pot if i remember properly
