Fix Silk PLA Stringing: Why More Gloss Means More Strings
Silk PLA strings more than the plain PLA you’re used to, and moisture or retraction alone do not explain why. Here is what Bambu…
Fix PETG Layer Separation: Why the Filament That Resists Warping Still Cracks
PETG resists the layer separation that plagues ABS, but print speed outrunning nozzle temperature, a flow ratio pushed too low, or cooling copied from…
Fix TPU Stringing: Why More Retraction Makes It Worse
TPU strings because it compresses under retraction instead of pulling back cleanly, so adding more retraction the way you would for PLA often jams…
Fix PETG Stringing: Why PETG Webs When PLA Comes Out Clean
PETG strings because its melt stays soft and stretchy across a far wider window than PLA’s, so the strand draws out instead of snapping.…
Fix AMS Not Feeding Filament: Why Multi-Material Systems Jam and How to Clear It
AMS, CFS, ACE Pro, CANVAS and MMU3 all jam for a short, predictable list of reasons: a damaged spool, debris in the feed path,…
Fix Nozzle Dragging: Why the Hotend Catches and Gouges a Print
A nozzle that scrapes or gouges the top of a print during a travel move is a clearance problem, not stringing or vibration. Here…
3D Print Overhangs: Why They Droop and How to Print Steeper Angles
Overhangs droop and curl for predictable reasons: gravity pulls on the unsupported fraction of each line and trapped heat lifts the free edge. Here…
Pressure Advance Calibration: Why Corners Bulge and How to Fix It
Pressure advance explained: why corners bulge or starve, and the real calibration steps for Klipper, Marlin linear advance, OrcaSlicer and Bambu.
Input Shaping for 3D Printers: Calibrating Resonance Compensation with an Accelerometer
Klipper’s input shaping uses an accelerometer to measure how a printer’s frame actually resonates, then shapes motion commands to cancel that ringing out instead…
3D Printer Belt Tension: Diagnosing Layer Shifts, Ringing and How to Fix It
Loose belts cause layer shifts and ringing near corners; overtight belts wear bearings and make motors skip. How to test tension properly and adjust…
