๐ ๏ธ Maintenance Guide: Lubricating the X/Y/Z Axes¶
Regular lubrication is essential for keeping your printer running smoothly, quietly, and accurately. This guide covers the proper lubrication procedure for the X/Y linear rails and the Z lead screw(s), following best practices for Bambu Lab-style printers.
โ Prerequisites¶
Before starting the lubrication procedure, make sure you have the correct maintenance products:
- โ Wanhao Maintenance Oil โ 30ml (for X/Y)
- โ Wanhao Maintenance Grease โ 30ml (for Z axis)
- โ Or, get both in the Wanhao Maintenance Oil & Grease Pack โ 2ร30ml
Info
These lubricants are safe for 3D printer components and recommended for linear rails and lead screws. Avoid household substitutes.
๐ง Recommended Lubrication Schedule¶
Axis | Recommended Product | Frequency |
---|---|---|
X/Y | Light machine oil | Every 1โ2 months or ~300 hours of printing |
Z | Grease (thick) | Every 3โ6 months or ~500 hours of printing |
SmartPad Notifications
Your SmartPad will automatically show maintenance reminders (lubrication, cleaning, etc.). Check the System Notifications regularly from the main menu.
โ๏ธ Required Tools & Materials¶
- Light oil (e.g. PTFE oil, sewing machine oil)
- Grease (lithium, silicone, or suitable for threaded rods)
- Lint-free cloths
- Cotton swabs or small brush
- Disposable gloves (optional)
๐งผ Preparation Steps¶
- Turn off the printer and unplug it.
- Manually move the printhead and bed to access all rails and screws.
- Use a cloth to clean old grease, dust, or debris from all mechanical parts.
๐ข๏ธ Lubricating the X/Y Axes (Linear Rails)¶
The X and Y axes move along linear guide rails with internal ball bearings.
Instructions¶
- Apply 1โ2 drops of light oil directly on each rail.
- Manually move the printhead and gantry across all directions to distribute the oil.
- Wipe away any excess oil.
Don't Use Grease
Never use grease on X/Y rails. It attracts dust and can clog the internal bearings.
โ๏ธ Lubricating the Z Axis (Lead Screw)¶
The Z axis uses a lead screw that lifts the build plate vertically.
Instructions¶
- Locate the lead screw(s).
- Apply a thin layer of grease with a swab or brush.
- Move the bed up/down manually or via the printer menu to spread the grease.
Note
If old grease is dark or sticky, clean it off before applying fresh grease.
โ Final Tips¶
- Use only compatible lubricants for plastic and metal parts.
- Don't over-lubricate โ excess can attract dust.
- Avoid products like WD-40, which are solvents, not lubricants.
๐ Maintenance Reminders¶
- Add lubrication to your monthly maintenance checklist.
