I’ve been experimenting with reducing speed and acceleration on my Ender 3 V3 KE to address noisy X-axis movements, an issue many users seem to have. I tested several XYZ calibration cubes and found that cutting speeds to 50% and accelerations to 20% of the default values worked best—reduced noise with no significant increase in print time.
However, when printing a larger model, I ran into a problem. Around layer 77, the extruder motor was spinning, but no filament was feeding. I stopped the print, tried retracting manually, but the filament was stuck. After disassembling the hotend, I found a clog in the heat break. I managed to clear it, and now the printer is working fine again.
This is my first 3D printer, and I’ve only printed a few small models so far. Could lowering speeds have caused this? Should I also adjust filament flow, or was this just bad luck? Any advice would be appreciated!
