Print Shifting/Skipping/Drifting

Description of Problem

During print jobs, shifting/skipping/drifting can occur in Y-axis or X-axis direction. Sometimes, this issue will occur in both directions at one time. There are hardware and software related components that can cause skipping/shifting/drifting.  

 

Causes + Solutions

  • Friction from tight parts - Most likely caused by friction between the carbon rods and the sliders.
    • Solution: Plastic shavings can also cause skipping, which can be brushed out with a Q-tip after slightly popping the sliders off of the carbon rods. Let the sliders rest on the carbon rods so the belts don't snap! See the image on the right below with the Q-tip underneath the slider.
       
  • Nozzle too low to the bed - The nozzle z-height position is too close to the bed during a print job.
    • Solution: Recalibrate Bed Location and/or increase the bed height offset or a corner offset manually by increments of 0.1mm. Please view the Bed Level Calibration article for more details. 
       
  • Nozzle running into warped corner of print - Warped prints are a product of an uneven bed.
    • Solution: Change your offset values to be more accurate. Please view the Bed Level Calibration article for more details. 
       
  • Printer is shifting only left to right (X-Axis) - The evenness of the Rack, the position of the Rack Gear, the uniformity of the Carbon Rod(s), the operation of the Motor, and the friction of the Motor Carriage on the carbon rods will need to be checked to ensure these are in good working condition.
    • Solution: Please view the X-Axis Services article to check each part for issues. 
       
  • Printer is shifting only front to back (Y-Axis) - The friction from the Slider(s), the tension of the Y Belt on either carbon rod, and the tension of the Y belt underneath the print area will need to be checked to ensure these are in good working condition.
    • Solution: Please view the Y-Axis Services article to check each part for issues. 
       
  • M3D Software - If hardware is confirmed to be in good working condition, our M3D Software might be causing the shifting/skipping/drifting.
