Extrusion Feedrate Issue?

Hi, I went through these settings to calibrate federate

M501 ; Get current E value
Mark 50mm on filament,
Extrude 50mm,
Measure differance,
(wanted_length/measured_length)*old_M92 E value = New E value
M92 E#
M500 ; Save Value
M501 ; Check to see if value has saved.

Now I have no extrusion at all. When I check the code it reads that min and max extrusion speed is set to 0.00.

< 12:34:17: echo:Advanced variables: S=Min feedrate (mm/s), T=Min travel feedrate (mm/s), B=minimum segment time (ms), X=maximum XY jerk (mm/s), Z=maximum Z jerk (mm/s), E=maximum E jerk (mm/s)
< 12:34:17: echo: M205 S0.00 T0.00 B20000 X20.00 Z0.40 E0.00

Any ideas how I get out of this corner?
