Printer Maintenance Scheduler
Maintenance is really about hours run, not calendar time — this converts your print habits into an actual next-due date.
Why hours matter more than the calendar
A printer running 40 hours a week wears through belts, bearings, and nozzles far faster than one running 5 hours a week, even though a calendar-based schedule would treat them identically. Tracking hours (or a close proxy, like average weekly usage) gives a maintenance date that actually reflects wear instead of just time passed.
What counts as "maintenance" varies by printer
Belt tension checks, rail or rod lubrication, nozzle inspection, and firmware updates are common across most machines, but the specifics and intervals differ by printer — check your printer-specific guide (Bambu Lab, Prusa, Ender 3, Voron, and others are covered on this site) for the actual checklist to run once this date comes due.
Log it so this stays accurate
Each time you actually do maintenance, note the date and reset from there — this only stays useful if the "last maintenance date" reflects reality rather than a guess from months ago.
