@RocketSled Which brand of PETG do you print? I wonder if that might have anything to do with it.
I’ve printed a wide range of different brand PETG’s on mine, so if there was a problem that could be attributed to brand, I wouldn’t know which to pin the blame on. In general I’ve been a fan of Elegoo Rapid PETG, though, because in general it prints high quality, and very, very fast (faster than high speed PLA!) and very inexpensive. My only grip with it is that it comes on a cardboard spool.
All that said, I’ve logged 1750 print hours on my X1C. There was some wear on the wiper, although not really obvious if you don’t know what to look for. With that as a reference, I’ll be more vigiliant inspecting it in the future. Today I replaced the wiper and the entire hotend and nozzle, so it should now be back to factory “good as new” condition.
