Default settings problem Prusa I3

Hey everyone, I am having an issue with my Prusa I3. Whenever the printer gets disconnected from power, the esteps / mm value changes back to default, 94.4 steps/mm. I upgraded my extruder so I need a value of about 725 steps/mm for it to work. Is there a way that I can change my default setting so I dont have to spin the little knob 5000000 times every time I want to print something? PS it also reverts to default when I hit emergency stop on Repetier. Thanks.

You have EEPROM enabled, so either disabled or save your changes via display or gcode.

On Marlin firmware you can change the settings for the knob in configuration h file under the display selection.

Thanks! I managed to use the Marlin Firmware to change the setting to 725 esteps/mm, but when I did that it changed everything else to 0. The marlin firmware config shows values of 0 with red filled backgrounds. I see now that I need to change all of those setting and upload them. My problem is now that there are setting on the printer lcd screen that dont seem to be on the marlin firmware.

Printer has:

accell
vxy-jerk
vz-jerk
ve-jerk
vmax x
vmax y
vmax z
vmax e
umin
utrav min
amx x
amax y
amax z
amax e
a-retract
xsteps/mm
ysteps/mm
zsteps/mm
esteps/mm


the marlin firmware does not have all of these settings, or at least they arent called the same thing. any tips? I dont want these values to become zero simply because I cant input a value with marlin. Thanks. Ive included a pic of my marlin firmware.

or is there a way to only save 1 setting to eeprom?

Yes there is, via display: go to settings and change the steps per mm there and then save it or via gcode M92 and then M500 so you will do M92 e725 and then M500
