Use this tag for questions related to specific movement of the Y direction of the printer - Questions about a machine or 3D model's Y-axis
For questions regarding troubleshooting or design of a 3D Printer or 3D model's Y-axis.
For cartesian printers, the Y-axis is usually the direction of horizontal movement of the build plate, to the maximum length of the printer.
For delta printers, the Y-axis is used for, and defines, the movement of the second stepper associated with the second Y-axis tower.
This is an axis or shaft direction in the Cartesian coordinate system. Three axes describe the complete movement of the 3D printer. The Y-axis is usually the horizontal movement of the platform from front to back when facing the a Cartesian style printer, or the horizontal hotend movement to front and back for non-moving platforms in the Y direction (e.g. CoreXY or H-bot printers).
