[[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 ==
[[File:Set_eeprom2.png|none]]
#Navigate to [[File:Settings Controls.png|link=Settings & Controls]]#Click on the [[File:Options.png|link=Options]] tab
#Connect to your printer
#In the '''EEProm''' section click on [[File:EEProm_configure.png|link=Options/EEProm]]#Change the '''Steps per mm:''' to correct for any discrepancy you find in your movement distances. [[File:Set_eeprom5.png]]
=== Equation ===
Here is the equation to find the correct value:
<code>Desired_Steps_Per_mm New_Value = Actual_Steps_Per_mm * Current_Steps_Per_mm 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.
