Layer Shifting
Layer shifting occurs when the print head loses its position, causing all subsequent layers to be offset. The result looks like the top portion of the print is slid sideways from the bottom.
Example
Root Causes
Loose or worn belts ā X/Y axis not holding position under acceleration
Print speed too high ā stepper motors skipping steps
Stepper motor current too low ā insufficient holding torque
Obstruction in the print path ā nozzle collision or blob knocked head
Loose pulley set screw ā pulley spinning on shaft
Overheating stepper drivers ā thermal throttling causing missed steps
Validated Solutions
Check and tighten all belts ā they should sound like a low guitar string when plucked
Reduce print speed by 20-30% and test
Check all pulley set screws and tighten with hex key
Inspect stepper drivers for overheating ā add cooling if needed
Check for any print head obstruction or blobs on the model
Increase stepper motor current (if using adjustable drivers like TMC)
Check and tighten eccentric nuts / linear rail carriages
