I am building the older version of ZenXY since I already have most of its hardware. I am running into a problem with the triangular block that is supposed to depress the mechanical switch of the X endstop. As soon as the triangle block attempts to press the switch, the belt on which it is mounted caves in. As such, the block moves out of the way and goes around the switch without pressing it.
How is it suppose to work and what can I do to get past the problem?
