I forgot to mention that I use the A4988 STEPPER MOTOR.
I noticed that the new firmeware that uses the definition of which driver step you are using in Configuration.h.
/ **
* Stepper Drivers
*
* These settings allow Marlin to tune stepper driver timing and enable advanced options for
* stepper drivers that support them. You may also override timing options in Configuration_adv.h.
*
* A4988 is assumed to be unspecified drivers.
*
* Options: A4988, DRV8825, LV8729, L6470, TB6560, TB6600, TMC2100,
* TMC2130, TMC2130_STANDALONE, TMC2208, TMC2208_STANDALONE,
* TMC26X, TMC26X_STANDALONE, TMC2660, TMC2660_STANDALONE,
* TMC5130, TMC5130_STANDALONE
*: ['A4988', 'DRV8825', 'LV8729', 'L6470', 'TB6560', 'TB6600', 'TMC2100', 'TMC2130', 'TMC2130_STANDALONE', 'TMC2208', 'TMC2208_STANDALONE', 'TMC26X' , 'TMC26X_STANDALONE', 'TMC2660', 'TMC2660_STANDALONE', 'TMC5130', 'TMC5130_STANDALONE']

it ends up causing me this self-leveling problem. and loss of steps.
