<p>The issue was the X-axis top smooth rod came out.  this caused the extruder to bang around and shift on the Y-axis when it shifted forward. thank everyone for their help. </p>

<p>My Y-axis on my Monoprice maker select running ramps 1.4 and Marlin makes a thud noise when moving every now and then.  I have noticed a 1 to 2 mm shift in the print when this occurs.  I tighten the belts and alas no joy.  I ordered new bearings which should be coming Monday.  I also tried slowing the print down and still get the same result.  Anyone have any ideas.</p>

# Y-axis slipping causing failed prints

(Asked by: username_0 on 2017-11-10)

My Y-axis on my Monoprice maker select running ramps 1.4 and Marlin makes a thud noise when moving every now and then. I have noticed a 1 to 2 mm shift in the print when this occurs. I tighten the belts and alas no joy. I ordered new bearings which should be coming Monday. I also tried slowing the print down and still get the same result. Anyone have any ideas.

**Tags:** marlin, ramps-1.4, y-axis
