General Troubleshooting Tips
Calibrate Before Printing
Most print issues trace back to calibration. Before troubleshooting a specific problem, ensure your printer's bed is level, your Z-offset is correct, your E-steps are calibrated, and your PID values are tuned. A well-calibrated printer eliminates the majority of common issues.
Keep Filament Dry
Moisture is a silent quality killer. Nylon, PETG, TPU, PVA, and PC are all highly hygroscopic. Store filament in airtight containers with desiccant. If you hear popping or hissing during printing, your filament needs drying (food dehydrator at 50–65 °C for 4–8 hours depending on material).
Change One Variable at a Time
When troubleshooting, resist the urge to change multiple settings at once. Adjust one parameter (temperature, speed, retraction), print a test, and evaluate before making another change. This methodical approach helps you identify what actually fixed the problem.
Use Test Prints
Standard calibration models save time: temperature towers for finding the right temperature, retraction tests for tuning stringing, benchy boats for overall quality assessment, and bridging tests for overhang performance. These are faster than reprinting your full model each time.
