Z-axis encoder connection diagnosis

[bar]

@Insulator

Is there any known failure mode for the sensors where power-cycling them would make them work again?

Not that I can think of. That is super strange.

@Insulator

The 2 likely culprits seem to be:

• A poor connection on the z-axis motor, triggered by vibration from the spindle. Disconnecting and reconnecting the cable at the sled does seem to rectify the issue which makes this seem likely. I’ve tried pulling the individual pins from the connector and pinching them slightly to tighten up the connection, without any lasting success.

Is it possible that unplugging it and re-plugging it is just giving us a new and good connection?
