ER68 - The humidity in the Material Station is high

The Material Station has detected that the relative humidity inside the chamber is high. This error occurs when the relative humidity inside the Material Station is over 40% for an extended period of time.

This error will not interrupt the printing process and can be dismissed, but it is a warning that the quality of the materials may degrade, especially moisture-sensitive materials such as PVA.

There can be several reasons for a high humidity inside the Material Station:

Open door Always ensure to keep the door of the Material Station closed, except when loading or unloading spools of material.
Humid environment Place the Ultimaker S5 Pro Bundle in a suitable location. In very humid environments, the dehumidifier inside the Material Station will struggle to maintain an RH of 40% as more regeneration cycles are required.
Missing seals The door of the Material Station is not sealed air-tight, but there should be no gaps at the sides. Ensure the hard plastic seals are correctly installed. These are located at each side of the chamber. If one is missing, contact your local reseller or reach out to support for a replacement.

After checking the Material Station and the environment as described above, power down the Pro Bundle by disconnecting the power cable from the Material Station. After a few minutes, reconnect the power cable and turn on the Ultimaker S5.

Note: The ER68 error message will not appear during the first 12 hours after the Material Station is powered on. This is to give the dehumidifier enough time to restore the relative humidity inside the chamber and regenerate.

If the error doesn't pop up again, the problem is solved. If the error does reappear, or if you see ER67 instead, there could be a hardware problem with the dehumidifier. Please contact support and include your log files for further assistance.
