Ratation_distance

General Discussion

Basic Information:

Printer Model: Original
MCU / Printerboard: SKR-PRO-V1.2

What is the setting value of ratation_distance for Z-axis stepping motor in printer.cfg?

full_step_per_ratation: 200 (1.8)
microsteps: 16

Ball lead: 5
deceleration ratio: 1/30
staps_per_mm: 19200

200*16/19200=0.166666

It seems to be spinning even though I set 0.166666 for ratation_distance.
Is it possible to set a value smaller than 1?

If your “step per mm” value is known and correct then see Rotation distance - Klipper documentation

Verification is quite easy:

  1. At an adequate spot, measure the distance from your head to the bed
  2. Move the haead or bed up or down 10 mm
  3. Measure again at the spot
  4. Calculate the difference. It should be 10 mm
