A mechanical stop is mounted on both the top and bottom of Joint #3. However, only the position of the lower
limit mechanical stop on the top can be changed. Do not remove the upper limit mechanical stop on the
bottom because the origin position of Joint #3 is determined by this stop.
5. The upper end of the shaft defines the maximum stroke position. Move the lower limit mechanical stop down by the length
that you want to limit the stroke.
For example, when the lower limit mechanical stop is set at the "420 mm" stroke, the lower limit Z coordinate value is
"-420". To change this value to "-320", move the lower limit mechanical stop down by "100 mm". Use calipers or similar
tool to measure the distance when adjusting the mechanical stop.

6. Tighten the set screws (2 × M6 × 6) of the lower limit mechanical stop firmly at the positions shown in the figure below
(one in the helical groove and one on the cylindrical surface).
