Z Motor Brake Not Activating

Hey Loren,

then I would check the contacts of the connectors. Unfortunately these Amphenol / Molex connectors are only tin-plated and sometimes make problems.

3A) Checking the wire connections:

ENSURE THE POWER IS OFF BEFORE DISCONNECTING OR RECONNECTING ANY WIRES!

Are you using aftermarket cables (like route1 cables from etsy)? If so, the very first thing to do is remove them and replace them with the factory cables. Use of aftermarket cables will void your warranty. DO NOT CONTACT SUPPORT IF YOU ARE USING AFTER MARKET WIRING.

If you having an issue with the Z axis and have removed the curly cable (for aftermarket cable in a drag chain), the curly cable is required and has a wire cross. Without this, the Z axis will not work correctly. See Here: Onefinity Wiring Diagram
Disconnect all wires on the rail that isn’t moving, from controller to motor, triple check all 4 pins inside each connector are present, straight, and leveled with each other. Then reconnect all connections, ensuring they fit very snuggly and 'snap ’ together. Here’s some pictures of a bad wire and a pin pushed in.

Push in pin: bad wire on back side of connector.

Bad wire on backside of connector:

Wire that comes out:

If a pin is pushed in, you can try grabbing it and pulling it forward with a pair of tweezers. If you cannot reach it this way, you can remove the tube following this video and push it back into place from the back of the connector. If it’s an inner tube wire, follow this video to gain access to the inside wire: Support : How to Access the inner tube motor wire

There is also a ‘hidden’ connection inside the tube (these inner tubes have a wire cross required for correct operation just like the z curly cable), where the motor and inner tube wire connect. You will need to watch the inner tube motor wire video (above) to check that connection as well. If you cannot remove the end cap to access the inner tube wire, you may need to use a dowl rod or the like to push it out from the backside in the tube.
