Troubleshooting

Choose an entry based on the symptom you see. After each step, re-check whether the problem is gone; do not change multiple settings at once.

Trackers Not Found by the Software

1. Confirm the receiver has its antenna attached and is connected to a USB port on the computer.
2. Confirm the trackers are on and sufficiently charged.
3. Try another USB port on the computer, avoiding a dock without its own power first.
4. Close duplicate SlimeVR instances, then restart the software.
5. Check whether the trackers and receiver are still paired and whether the firmware versions match.

Shows Connected but No Movement

1. Confirm the corresponding tracker has not auto-powered off or run out of battery.
2. Move the tracker closer to the receiver and reduce obstruction.
3. Restart the trackers and SlimeVR.
4. If the device still does not respond, note the indicator-light state and contact support.

Frequent Dropouts or Motion Delay

• Keep the area around the receiver antenna clear.
• Do not place the receiver behind the computer case or against large metal objects.
• Reduce the distance between the trackers and the receiver.
• Try connecting directly to a USB port on the computer.
• Restart the computer rather than only shutting down and turning it on again.

Body or Feet Facing the Wrong Direction

1. Check whether the trackers are assigned to the correct body parts.
2. Check whether the left and right devices are swapped.
3. Check whether device orientation matches the wearing diagrams.
4. Re-run the full reset and wearing calibration.

Drift Is Too Fast

1. Confirm the trackers are secured and not sliding on clothing.
2. Re-run device calibration.
3. Re-run the full reset and wearing calibration.
4. Move away from obvious magnetic or mechanical vibration interference.

Can't Crouch or Head Height Is Locked

1. Confirm the headset itself moves up and down normally in SteamVR.
2. Confirm no tracker is incorrectly assigned to the head, left hand or right hand in SlimeVR.
3. In SlimeVR, re-run the full reset and body wearing calibration.
4. In VRChat, confirm the real height and full-body tracking settings — see VRChat Setup.

Leg Raise, Kick or Bend Direction Is Wrong

1. Check whether the thigh trackers are fixed just above the knee facing forward, rather than on the side of the thigh.
2. Check whether the shin, foot and hip devices rotate or slide during movement.
3. Verify the left and right assignment in SlimeVR.
4. Re-run the full reset and body wearing calibration; if foot trackers are assigned, also run the foot wearing calibration.

Trackers and Model Offset Far Overall

1. Stop moving and confirm the straps and chest mount have not shifted.
2. In SlimeVR, run a full reset and stay upright until the countdown ends.
3. Run the body wearing calibration, then complete the in-game calibration in VRChat.
4. If the offset only happens on one model, re-adjust that model's skeleton and re-bind.

A Joint Is Locked or a Body Part Rotates on Its Own

1. Check whether the corresponding tracker is still updating in SlimeVR.
2. Check whether the tracker at that point is loose, upside down, or assigned incorrectly.
3. Restart SlimeVR and the trackers, then re-run the full reset and wearing calibration.
4. If it only happens after switching models, check the VRChat model skeleton and full-body tracking nodes.

Cannot Charge

1. Confirm the trackers are oriented correctly and fully contact the dock.
2. Clean dust and dirt from the charging contacts.
3. Use a reliable USB cable and a power source that meets the product label.
4. If abnormal heat, bulging or smell appears, stop charging immediately.

Cannot Connect After a Firmware Update

Confirm the tracker and receiver use compatible firmware versions. Do not keep trying different firmware for different models in a row; record the update file name, tool prompts, versions and indicator-light state, then contact support.

Still Not Resolved

Go to Contact Support and prepare the device model, firmware version, system version, SlimeVR version, reproduction steps and video.
