Step motor controls must correct for motor nonlinearity and
resonance, otherwise the motor will not output as much power or
smoothness as is expected. Geckodrive stepper drives increase
usable motor resolution by microstepping and output more torque
than competing drives with our proprietary anti-resonance
algorithms.

Smoothieware, which is as capable as Marlin or Repetier but easier
to configure.

I tested it for one MA860H motor driver.
It works well with the marlin2.0 firmware.
So I tried to change all the motor drivers to MA860H.
In the end, Marlin 2.0 gave up and decided to use Smoothieware.
Now it works well with smoothieware.
