Z axis is crazy (solved, replaced extension wire)

Hey Tim,

@Splinterfinger

Checked the forum and did some tests with the joystick . Sometimes the Z goes in the correct direction, sometimes it goes in the opposite direction of what is supposed to

an issue where the Z goes into the wrong direction or plunges into wasteboard can be found repeatedly in the forum. Usually it’s a cable connector problem, possibly in combination with the lack of strain relief on this machine (see my comment here).

The manufacturer addresses this in this document:

Note: Any time the axis moves in the opposite direction than what you direct it to, it’s 100% of the time a bad wire/connection. Sometimes, something as simple as disconnecting and reconnecting the wires connection solves it. Follow below for more help and examples.
