ER72 - Material Station communication failed

If you have see this error, the Ultimaker S5 Pro Bundle had a communication failure while changing or unloading filament. This has likely occurred either during an end of filament procedure or at the end of a print job.

In case of an ER72, you will have to perform some manual actions to restore the Pro Bundle. Restoring is not difficult but, unfortunately, it is not possible to preserve the print progress. Please perform the steps described in the tabs below:

Remove filament from print core Rewind the spool Reassembly

If the error appears while the filament is still loaded into the print core, please try to manually remove it. To do this:

  • Open the Air Manager (if present)
  • Remove the clamp clip of the Bowden tube at the print head
  • While pressing down the collet, pull the Bowden tube up to remove it from the print head
  • Manually pull the filament out of the print head (it is recommended to use pliers to grip the filament)
  • Cut off the end of the filament and ensure a nice, sharp tip

Now proceed to the next steps in the second tab.

Note: If it is not possible to remove the Bowden tube from the print head, you may need to heat up the print core first. Power cycle the machine and heat up the print core via the menu.
