I recently got an Ultimaker 2 Extended +. The material feed worked. I connected to Cura 2.5 and got firmware update. Now, the material feeds in reverse. Now the firmware version: Maintenance/version Vers:_2.4ex
I loaded Custom firmware Program Files/Cura 2.5/Resources/Firmware MarlinUltimaker2extended-plus.hex but it did not solve the problem.
I will appreciate any help getting the correct firmware or other solutions.
