Customize Extruder Printable Region: Different printers have different default printable area ranges.
X/Y: The starting point position for printing on the X/Y axis.
X/Y Size: The maximum printable size on the X/Y axis, measured in millimeters.
Extruder Offset:
Extruder Offset X: Refers to the offset between two nozzles in the direction of X-axis. We set the left extruder as the default nozzle. When we calculate the correct extruder’s position, we should subtract 25mm offset (which you set for X offset) in the X-axis direction.
Extruder Offset Y: Refers to the offset between two nozzles in the direction of Y-axis. We set the left extruder as the default nozzle. When we calculate the correct extruder’s position, we should subtract 0mm offset (which you set for Y offset) in the direction of Y-axis.
Virtual Extruder Offset X: Refers to the right extruder’s virtual offset on the X-axis.
Virtual Extruder Offset Y: Refers to the right extruder’s virtual offset on the Y-axis.
Note: The value is used to check whether models are placed outside the extruder’s printing range if both Extruder Offset X and Y are set to 0.
For example, if you set Virtual Extruder Offset X to 0mm and choose the right extruder for printing, you will see the printing range is same as the left extruder, as shown in Figure 10. If you set Virtual Extruder Offset X to 25mm and choose the right extruder for printing, you will see the printing range as shown in Figure 11.
