[[File:Set_eeprom1EEProm2.png|right|frame|<center>EEPROM settings can be found under the Configuration tabOptions menu.</center>]]MatterControl can set EEProm settings for both Marlin and Repetier firmwares.
== Procedure ==
Here is the equation to find the correct value:
<code>New_Value = Actual_Distance * Current_Value / Actual_Distance * Desired_Distance</code>
So if the current value for X was 80 and the printer only moved 97mm when trying to move 100mm, the equation would be: <code>97 * 80 / 97 * 100</code>The new X Steps Per mm to 7782.47.6
The same principle applies for the extruder. If over/under-extruding, use this equation.
