1st 3d printer. assembly went well no problems. when powered up, run auto home, x axis just vibrates and doesnt move, thought the belt may have been loose but the actuall motor is studering. if i try to print the x axis moves fine. second problem is the z axis isnt level. ill adjust the bed, run auto home, the right side motor will start to move befor the other, the when i recheck bed adjustment, it will be way off. but you can see the right move start and stop at different times than the left, which is really weird considering the are wired togeather… and 3rd problem is filamebt is coming out of nozzle when not printing. i was so excted for this and couldnt wait to try a 1st print, but i cant get that far. any help would be appreciated.
