Marlin 2.1.1 Configuration.hsettings ignored

I'm having problems upgrading to Marlin 2.1.1

I have a RAMPS 1.4 motherboard with A4988 stepper drivers. When I compile with
DEFAULT_AXIS_STEPS_PER_UNIT { 80.0, 80.0, 1259.84, 100.0 }
the X and Y axis move 50 mm when I give a G1 Y10 command, for example.
Setting the steps per unit manually with M92 X80.0 Y80.0 the axes perform normally.

I'm about out of ideas. I have not had this problem with previous versions.

Help, please.

... this could show, that you have 16 steps per mm instead of 80, what you defined.

Recalculate with motor type, microstepping amount, gear ratio, screw measure and such ...

You NEED to reset your eeprom to firmware defaults.

If you do a M503 after power up and look for the M92 line, you will probably find that the eeprom has different settings

After you first initialize the eeprom, the values stored in eeprom take precedence

No matter how many time you then update the steps/mm in code and recompile, it will continue to use the old data in eeprom

Until you reset eeprom data back to firmware defaults, M502 load firmware defaults M500 save to eeprom

Or you enable EEPROM_INIT_NOW wihch resets eeprom back to firmware default on each new firmware upload
