Hotend clogging
Any advice from public on following issue? After more than 24000 hours of flawless printing on MK3S I'm getting hotend clogs frequently. What is embarrassing, after cleaning (cold pull) I got the same problem again after some 60 hours of print. And than again after some 20 hours. I changed the nozzle (even if the original one seemed in perfect shape - I do not print with abrasive filaments), no improvement. Occurs independent on filaments used.
Any idea anybody, what could be the root cause of such problem?

Inspect your Bondtech gears.
They can wear especially with abrasives; I've no data on how long they last with plain filament.
...and the extruder idler bearings (inside the idler gear) can wear as well.
Cheerio,
