Your 3D printer relies on timing belts to translate motor rotation into precise linear motion. When those belts get loose, the symptoms can be subtle at first — slightly rounded corners, faint ghosting on walls, or minor dimensional inaccuracies. But as the problem worsens, you’ll start seeing layer shifts, ringing artifacts, and prints that look…
You’re hours into a print, everything looks great, and then suddenly — the layers shift. What was supposed to be a clean vertical wall now has a visible offset somewhere in the middle, as if the top half of your print decided to take a step sideways. This is layer shifting, and when it happens…
Layer shifting is one of those print failures that hurts the most because it usually happens hours into a print. Everything looks perfect, then suddenly the layers are offset by a few millimeters and your print looks like a building after an earthquake. I’ve lost count of how many overnight prints I’ve woken up to…
