Maintenance

A category about routine 3D printer maintenance: lubrication of linear rails and lead screws, nozzle cleaning, first-layer tuning, extruder feeder diagnostics, regular XY belt tension checks, and consumable replacement. Universal guides for FDM printers — the methods apply to any brand, from Creality Ender and Bambu Lab A1 to Flashforge Adventurer and Snapmaker U1, with notes on frame geometry and feeder type (Bowden vs direct drive).

What to do on a schedule: lubricate the rods every 100–150 hours, clean the nozzle and feeder gear every 5 spools, check belt tension every 50 hours, wipe the bed with isopropyl alcohol after every print, and verify first-layer geometry across all corners once a month. Skipping maintenance is the number-one cause of "sudden" quality issues after 200–300 hours. The articles below give concrete procedures with intervals, consumable lists, and per-step time estimates — not vague reminders.
