Do you mean to say I should use a lower-valued brake resistor?
In terms of the other factors, I have the brake resistor enabled in config, and haven’t had issues since setting a more negative dc_max_negative_current value 
Thank you @Samuel , added your changes and for me it’s still not working perfectly;
It homes nicely and works as expected, but only the first time.
Every homing cycle after that the offset increases slightly (while it is hardcoded at the same value).
How is this possible? How to fix it?
(maybe it has something to do with both axis homing?)

It’s quite likely that the PWM input could interfere with homing.
Can you set odrv0.config.gpio1_pwm_mapping.endpoint to something else and then try again?
