What is the kinematics difference between a H-Bot and a standard cartesian printer? I guess the only difference is the dual Y-motor.
You can control them the same way as the Prusa I3 dual Z steppers. Wire them in serial or parallel to a single driver.
HBOT works similar to CoreXY if I'm not mistaken. So, open the Marlin config file in the Arduino IDE and Ctrl-F find 'core' or something. If I remember correctly there's a line that allows you to enable CoreXY Kinematics. Do this.
IMHO they don't. The X-motor is mounted on the Y-gantry. Both axis have their own motor. To avoid racking, the Y-axis often is driven by two motors.
That looks like a cartesian printer to me.
