    Shifted Bottom Layers

    FullSizeRender.jpgI'm having problems with my bottom layers after intalling new extruder parts. The same Greg's extruder parts that came with my Makerfarm. Here are pictures. I checked all of the hardware that I can think of for anything being loose. Motor gear set screws, X and Y rail wheels, hot end is secure, belts. One of the cubes is at full scale and the other was printed at half scale. The thing I noticed is that one has shifted layers in the X axis and the other in the Y axis.
