When limit switch can't workUpdated 2 days ago

If limit switch malfunction, homing fails, or no software alarm appears when manually pressing the switch, please follow the step-by-step troubleshooting below to identify the problem.

!!! Please replace [Good limit switch] and [Faulty limit switch] with the corresponding axis based on the actual situation.

E.g.: [Good  limit switch] = [X limit switch]  (the limit switch can work normally)

[Faulty limiti switch] = [Z limit switch] (the one cannot work)

Step 1: Disassemble the [Faulty limit switch] and wire it to an axis that runs normally.

Result:

- [Faulty limit switch] can not work, the problem lies with the limit switch.

- [Faulty limit switch] can work normally, the [Faulty limit switch] wire or the control board is defective(go to step 2)

Step 2: Then use the wire of the [Good limit switch] to connect the [Faulty limit switch] control board port, and trigger the [faulty limit switch]:

Result: 

- [Faulty limit switch] can work normally → the [faulty limit switch] cable is defective.

- [Faulty limit switch] still can not work→ the motherboard is defective.
