The evidence, printer by printer

A1

On the Bambu Lab A1

Fits, with limits Our interpretation of the manufacturer's information

How we read it: The grease page says "All Series" without naming the A1, and the A1 maintenance guide calls for lubricant grease on the lead screws. Together they support use on the A1 lead screws.

Limits

  • Maker (A1 guide): lead screws and extruder wheels only; "strictly prohibited to use lubricating grease on the X-axis linear rail".
  • Maker (A1 guide): use lubricant oil, not grease, on the Y-axis guide rail.
