Bambu Lab 3D Printer Error Code 0700_0100_0001_0001: How to Fix It

Q: What causes Bambu Lab error code 0700_0100_0001_0001?

This error is caused by Z-axis motor stall, typically due to insufficient lubrication on the lead screw, debris buildup, or mechanical obstructions preventing smooth Z-axis movement.

Q: How often should I lubricate my Bambu Lab printer's Z-axis?

Lubricate the Z-axis lead screw every 3-6 months with regular use, or more frequently if you notice any stiffness in movement or operate in a dusty environment.

Q: Can I use any type of lubricant on the lead screw?

Use only white lithium grease or PTFE-based lubricants specifically designed for precision machinery. Avoid oil-based lubricants that can attract debris or cause gumming.

Q: What if the error comes back after lubrication?

If the error returns, check for worn lead screw nuts, damaged linear bearings, or mechanical misalignment that may require professional service or part replacement.

Q: Is it safe to manually move the Z-axis when the printer is off?

Yes, it's safe to gently move the Z-axis by hand when the printer is powered off. This actually helps distribute lubrication and check for mechanical issues.

Abstract

Error code 0700_0100_0001_0001 (also known as HMS 0700) indicates a Z-axis motor stall on your Bambu Lab 3D printer. This typically occurs when the Z-axis lead screw lacks proper lubrication or has mechanical obstructions preventing smooth movement. Fixing this issue usually involves cleaning and lubricating the lead screw system.
