How to Fix Bed Leveling Springs Losing Tension

Step-by-step fix for bed leveling springs losing tension on Bambu Lab printers including X1C, H2D, P1S, and A1.

How do I fix bed leveling springs losing tension?

1
Replace stock springs with silicone spacers (solid mounts). They maintain compression indefinitely and eliminate the need for frequent re-leveling.
2
If keeping springs: compress them about 60-70% when leveled. Too little compression allows vibration to change their height mid-print.
3
After replacing springs/spacers: run a full manual mesh level across 25 points, then save to EEPROM (M500). Re-level every 10–20 prints or after moving the printer.

Pro tip: Stable bed leveling is essential for first-layer consistency. Silicone spacers are a $5 upgrade that eliminates this issue permanently.
