# Spotline V2: Troubleshooting

Machines are complex - making them run smoothly can be challenging. Below are common issues and how to solve them.

* **Motor won't move and immediately trips a VFD fault**
  * Load the correct parameters and run an autotune
* **Motion isn't smooth**
  * check Spikemark PID values
  * reduce load and check motion
  * check rigging for hang-ups
* **X-Groove sensor is tripping**
  * Check for x-groove
  * Check for cable "knuckle" at drum entry location
  * Adjust the x-groove sensor
    * Each sensor has a light that turns on when the bar is WITHIN PROXIMITY. If either light is out, you will see an XG.
* **Positioning is poor**
  * Separate motor and signal cables
* **Load cells**
  * Check load cell scaling
  * adjust minimum/maximum loads
  * check for interference/hangups

{% hint style="danger" %}
Manually releasing both brakes will release whatever weight is hanging from the Spotline.\
\
Keep in mind, the heavier the load hanging, the quicker it will come in when the brakes are released.\
\
The minimum release weight is 45lbs.

* **Manual Brake Release**
  * The Spotline has two brakes: Motor Brake & Load Brake. Each brake can be individually released from the [Stagehand](https://docs.creativeconners.com/docs/stagehand/stagehand-pro-5/stagehand-pro-5-operation#h.s1utptbqcu06). Each brake can also be manually released from the machine
  * Release the Motor Brake
    * insert the manual brake release handle (attached to the motor) into the brake at the top of the motor.
    * Push and hold the handle UP to release the motor brake
  * Release the Load Brake
    * insert the manual brake release handle (attached to the Spotline frame) into the brake.
    * Push and hold the brake handle AWAY from the machine to release the load brake.
