It's possible that the "bumps" or imperfections you're experiencing on your prints are due to several factors. Here are a few troubleshooting steps you can try:
-
Check your filament: Ensure that your filament is not tangled or binding in the extruder. Sometimes, irregular feeding can cause these bumps. Additionally, make sure the filament diameter is consistent and within the recommended range for your printer.
-
Retraction settings: Adjusting your retraction settings can sometimes help eliminate imperfections. Try increasing the retraction distance slightly to reduce any potential oozing or stringing.
-
Print temperature: Incorrect print temperatures can also lead to imperfections. Experiment with lowering or raising the print temperature to see if it makes a difference in print quality.
-
Z-hop: Enabling Z-hop can help prevent the nozzle from dragging across the printed part, which could cause imperfections. Experiment with enabling this feature in your slicer settings.
