Hello i designt this model for me to calibrate the e- steps of the X and Y Stepper Motors.

First you have to print this model in 100% scale.

Second measure it with a caliper if you have 100mm in each direction your e-steps are correct.

If its not you have to look what e-steps are integrated in your firmware with Prontaface.

For Klipper Users you have to look in your printer.cfg  x- Stepper and y- Stepper Change the rotation distance and you are fine…..

For Example in my Situation Stock Rotation distance was Factory 40 for X and y now after calibrate X 39.98 and Y 40.03 . I use Sonic Pad with my printer If the Count was Higher then 40 the model get smaller and If you under 40 the model will be bigger it is Not much but i had .3 and .2 differences.

It is the same procedure when you calibrate the e-steps from your extruder .

Therefore are many tutorials on youtube.

Hope you enjoy to calibrate and all printed parts will print in the dimensions that are they designt.

Hope you'll Like it and happy Printing.
