X-Axis actuator

X-Axis actuator

You'll need a 2.5M by 8mm screw, washer, and nut, which you likely have leftover from the original build. The actuator bar sits atop the Extruder carriage, utilizing an unused screw hole to activate the X-min microswitch when the nozzle reaches the bed's edge. This feature is adjustable, eliminating the need for a zero offset in the firmware for the X axis. Designed in OpenSCAD, the object can be easily edited if your extruder carriage differs slightly. The print lacks fine detail.
