Ultmaker 2 extruder running backwards?

lol.  You probably have the wrong firmware.  The UM2 and the UM2+ feeders run in opposite directions.  So you probably got the wrong firmware.  Also do a "factory reset" as sometimes when you downgrade or cross-grade the firmware it doesn't carry forward the eeprom values and a "factory reset" fixes this so that you have the correct directions for all the extruders.

 

ALSO

 

Seriously consider getting the tinker firmware instead of the Ultimaker version.  The tinker version is much better with amazing features like the ability to reverse the feeder without installing different firmware and the ability to continue a failed print and much more.

 

Tinker marlin is here:

You have probably flashed the wrong firmware, ie the firmware for the UM 2+ instead of the UM 2. Flash the proper firmware for your printertype and it should work correctly again.

 

edit: @gr5 beat me to it.

I really appreciate your responses, but I'm still not getting this too work.

 

first I reset the unit to factory resets - still backwards

 

second I redownloaded and reloaded U2 firmware - still backwards

 

third As a test I downloaded U2+ to see if that reverses the extruder - still backwards

 

Fourth  I tried the marlin alternative firmware - still backwards

 

Fifth.....I don't know.  I'm getting the firmware from github....I assume that is the right location.

 

Any ideas are appreciated

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
