Print speed and acceleration
Print speed is generally the reason behind this print failure. The missing lines/mis-extrusions are a result of printing or accelerating too fast. To change the acceleration settings on the controller, you need to run the “Print smooth” macro on the Duet controller or change it on the Control menu on the Workbench (RAMPS) controller. The acceleration and speed values can also be set in the slicer.
If the retraction distance is higher, the print may show missing lines or holes due to mis-extrusion. These holes generally show up right after the retract seam as seen in the above picture.
