Backward filament feed

Hello I have a few Ultimakers extended 2 + today i did a software update to them, after this when  i tried to insert material in instead of pushing it forward it will extract it!!! Basically the process of inserting material inverted , same for model printing!!

The UM2 and the UM2+ have reverse direction feeders.  You got the wrong software.  If you have a white feeder on your UM2 then use the "plus" firmware.  If you have a black feeder on your UM2 then don't use the "plus" firmware.  Just regular UM2 extended.

I forgot to mention you want to do a FACTORY RESET on the menu.  Some of those things (like steps/mm for the E axis) are stored in the eeprom area and different versions of the firmware (marlin) store it in different places so it's best to do a FACTORY RESET after installing firmware unless it was definitely 100% an increase in version from one UM official release to another official release.

 

For example if you switch to tinkerMarlin or from tinkerMarlin you definitely want to do a FACTORY RESET.
