[SOLVED Feeder motor works reverse while printing]

Hi 

I have an Ultimaker 2+ and the problem is:

When i tried to insert the material the feeder spins opposite way extracting it , and vise versa  . Firmware installed is for ultimaker 2 +.

Hello 

I have an UM2 + and the problem is that when i try to print something it goes all the way up and bangs in to the nozzle . I lower the build plate from the menu and i goes down and stops , no problem with lowering the build plate. But when i'm trying to calibrate the the build plate it goes up and do not stop like an inch from the nozzle,  before i use to adjust (calibrate) it by hand ,but now it bangs into the nozzle   !!!!

I checked the switch at the bottom it is ok!

I checked the connections on the board for the z axis it is connected!!

What could be the problem????

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!!
