ender-3-s1-klipper-btt-skr-mini-e3-v3's Issues

rotation distance should be 7.53???

sprite motor info:

• uses NEMA17 motor
• gear ratio: 3.5:1
• e-steps for sprite extruder pro
  • official value: 424.9
  • 431.2
  • 395
  • 420.69

With torque, the smaller the motor, the less there is. However, the use of a short gear train can address this.
The Sprite uses a 25 mm long pancake stepper motor that’s on the lower side of torque. But, in combination with the extruder’s 3.5:1 gearing ratio, Creality says the Sprite can create an extrusion force of up to 80N. For 1.75 mm filament, that’s a generous amount more force than you’re likely to need.

Klipper rotation distance

rotation_distance = <full_steps_per_rotation> * <microsteps> / <steps_per_mm>

so, 16 * 200/424.9 = 7.5311838079548137
