Error - Why Your E‑Pick Clicks—What It Means & How to Fix It

Understand the source of clicking noise in E‑Pick and how a firmware update resolves it.

Context

If you notice a clicking sound coming from your E‑Pick vacuum gripper, especially during operation in high-temperature environments, you're not alone. This article explains why the sound occurs, whether it affects performance, and how to resolve it with a simple update.

 

1. What’s Causing the Clicking?

The clicking sound is caused by the internal valve inside the E‑Pick rapidly switching ON and OFF. This happens as the gripper regulates vacuum pressure—particularly when the system is under thermal stress or operating near its vacuum thresholds. 

 

2. Recommended Fix: Update Firmware and URCap

Robotiq released a firmware update and URCap component patch that adjusts internal behavior and significantly reduces or eliminates the clicking noise.

To fix the issue:

  1. Update your E‑Pick firmware to the latest version by following this guide

  2. Ensure your URCap or component software is also updated.

 

This update optimizes valve cycling logic, especially under thermal load.

 

Conclusion

Clicking noises from the E‑Pick are usually harmless and caused by internal vacuum valve cycling. However, if it becomes frequent or distracting, applying the latest firmware and URCap updates should resolve the issue.
