I bought a used Taz 5 and I’ve had a great time calibrating and tuning ALL THE THINGS. However, I can’t shake this feeling that there will be components on the printer that wear out, or could already be wore out. Maybe a gear, maybe a belt, or something… I’ve read the Lulz documentation and read about bushings and lithium grease. However, I haven’t seen a good checklist going through the components checking for health. Has anyone written anything like that? Is there a list of parts that will wear out with heavy use and a way to do a health check on the components? I’m looking for photos of worn out extruder gears, broken parts, worn or mis-tensioned belts, common warrantied items, etc.
Am I being a 3D-printer-hypochondriac?
