Summary

Yet another calibration cube that I tried to keep fast to print. Made in sketchup, it is 25x25x25mm. You may resize it when slicing it in case you need other round numbers for your calibration.

It also makes a nice present for friends who are curious about 3D printing :D

Instructions

Print one cube, measure each axis with the caliper and recalculate your steps per axis as follows:

  • new_steps_per_axis = 25/measured_size_in_axis_in_mm * current_steps_per_axis.

Iterate until you are happy :)

I Have calculated that I need to change my Y axis steps to 94.912, but how do I change my steps per axis?

Hi! You must update your configuration file and load again your firmware. Actually, it depends on your firmware, is it Sprinter, Marlin or Teacup? In Marlin it's DEFAULT_AXIS_STEPS_PER_UNIT, in Sprinter it's _AXIS_STEP_PER_UNIT and in Teacup it's STEPS_PER_M_Y.
