Issue with homing on Marlin 2.0.7.2 ( ok with 1.1.9 )

Hi guys,

This is my first post here.
Please help to understand the following issue.
I have RigidBot 3D Printer ( Cartesian, 250x250x250, single extruder, no probes )
Successfully configured and installed Marlin 1.1.9 on it
Decided to go with Marlin 2.0.X
Well it did not go as smooth as I wanted to be:
I'm skipping all marazm with getting it compiled ( virtual studio + platformio + marlinauto + and so on )

Straight to the problem:
When I use 1.1.9 all my stepper direction is fine ( homing and linear moves )
When ported all the same setting to Marlin 2.0.7.2 based firmware homing direction is reversed but manual travel direction is fine ( G1 X Y Z is fine too )
I was bashing my head and cannot wrap my brain around what is going on, It just suppose to work. I did not change stepper wiring in any way. I can flash 1.1.9 back and it work as a charm.

What Am I missing ?
I included 2 config files ( 1.1.9 based and 2.0.7.2 based )
May be you can spot the problem?
Thank you

Took a Look for you.
Found only three lines inconstant
Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN disabled in Marlin 2.0.7.2 - Enabled in Marlin 1.1.9
#define Z_MIN_PROBE_ENDSTOP_INVERTING true // set to same logic as "Z_MIN_ENDSTOP_INVERTING".

#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN // Not enabled in Marlin 2.0.7.2

#define NOZZLE_TO_PROBE_OFFSET { 10, 10, 0 } // Numbers inconstant from Marlin 1.1.9 (44, -5. -1.85)


After Flashing did you try sending

M502 // Read Firmware defaults
M500 // Save Setting to EEprom

Thank you Robert,

Those inconsistencies due to my experiments with BLTouch on 1.1.9
And AFAIK they not suppose to affect homing moves ( well except Z stop logic )

I've only done M500 straight on first boot with new firmware (2.0.X), but did not do M502. Did not know about such command.
I will give it a try.

When I first flashed my 3D Printer Controller I had funny things happening that I could not explain.

Posted my problem and was immediately return a post telling me to exactly this, after completing the task everything work correctly.
M502 // Read Firmware default
M500 // Save Setting to EEprom
