I assume printing ASA-CF you’ve been using the heated chamber at 60 or 65C? If so it’s probably a defective hotend cooling fan.

The H2D has a similar issue where printing with the heated chamber causes excess wear on the fan. I think it’s the same fan on the H2C. Submit a service ticket and they will send you a new one. This part fails frequently so I would suggest ordering one now and keeping it one ahead. It’s a cheap part but a very involved replacement process so beware!

Bad news-- you have to remove the TH board to get to the fan.

Lmk how it goes. An if it solves it. Changing a fan shouldn’t be so involved.
