 From this formula we can calculate the new steps/mm by plugging in the values:
-<code>
-(new steps) = ( 100 / 102.09 ) * 90
-(new steps) = 88.16 steps/mm
+''Steps<sub>new</sub> = ( 100 / 102.09 ) * 90''
-</code>
+''Steps<sub>new</sub> = 88.16 steps/mm''
 Save the new steps to the printer with ''M92 E88.16''
 **NOTE**: This setting will not persist! You will have to either set the setting in the EEPROM (through printer menus) or in ''configuration.h''. The purpose of saving the setting like this, is to redo the calibration and test that it is accurate.
+To save the setting in ''configuration.h'' edit the following line:
+<code c>
+#define DEFAULT_AXIS_STEPS_PER_UNIT   {100,  100, 400, 88.16} // { X, Y, Z, E }
