Fore left edge is defined as 0,0. So depending where your physical endstops are sitting or where you home sensorlessly you have to define the right coordinates respectively. And depending on that you might want to change the following parameter under the X and Y stepper sections: ```auto homing_positive_dir: ``` Read here for further information on the parameters: > **[Configuration reference - Klipper documentation](https://www.klipper3d.org/Config_Reference.html#stepper)** Also read this knowledge base article about coordinates and homing: > [@Understanding X and Y Axes Limits and Homing](https://klipper.discourse.group/t/understanding-x-and-y-axes-limits-and-homing/10779): > > The X and Y Axis Klipper needs to know from its printer.cfg settings how far the X and Y axes can safely move without hitting the printer’s frame. It also needs to know where the origin (X=0 / Y=0) is. This origin is the beginning of the usable printer bed. In the following, we assume a Cartesian printer that follows the conventions of a [Cartesian Coordinate System](https://en.wikipedia.org/wiki/Cartesian_coordinate_system). This is also the reason why it is a quasi-standard to define the origin as the left-front corner of the bed. This way, all logic… --- _[View the full topic](https://klipper.discourse.group/t/hybrid-corexy-seems-to-need-inversion/12968)._
