Tankstick MAX loose spinner nut

Useful Answer

If a new Tankstick MAX spinner feels loose or wobbles around the shaft, inspect the spinner from inside the controller before replacing parts.

The likely fix is to open the Tankstick case and tighten the nut that secures the spinner assembly.

If one spinner does not move the mouse cursor at all while the trackball and the other spinner work, also inspect the small spinner connector on the PCB. A partially disconnected spinner plug can disable that spinner; reseating it may restore movement. If the socket itself is cracked and the connector will not lock in place, treat it as a PCB/hardware damage case rather than a software mapping issue.

Use this when:

• One spinner feels normal but the other spinner wobbles or moves around.
• The spinner shaft is visibly loose after removing the spinner knob.
• The issue appeared immediately after delivery or shipping.

Ask for a short video first if the symptom is unclear. If the video shows a loose spinner assembly rather than an electrical input failure, direct the customer to the official case-opening guide and have them tighten the spinner retaining nut.

Source Context

The customer received a new Tankstick MAX where one spinner felt smooth but the other spinner wobbled. Support identified the likely cause as a loose internal spinner nut and asked the customer to open the controller and tighten it. The customer later confirmed: "It was a loose nut like you said! Its much better now." A separate one-spinner-dead case found a partially disconnected spinner connector and cracked PCB socket; reconnecting restored spinner movement, but the cracked socket required hardware follow-up.
