  • Page 38: Endstops

    [7] Endstops Parts needed: Printed X-Endstop holder Printed X-Endstop holder End switch You will not need this Z-Endstop due to your inductive probe STEP 1 Time to attach your two end stops, one for each axis as seen in the image. First thing you need to do is insert the end switches into the printed parts.
  • Page 39 STEP 2 • Snap the x-axis end switch holder onto the two M8 smooth rods. STEP 3 • Snap the y-axis end switch assembly to the M10 threaded rod. The top ‘hook’ keeps the mount vertical.
  • Page 40 STEP 4 Now it’s time to position the two end switch assemblies. The point of this is to ensure the tip of the nozzle ‘homes’ to the front left corner of the bed. • First up is the x-axis. Position the X end-switch assembly so that the tip of the nozzle lines up with the left edge of the print bed when the switch makes contact with the x-carriage.
