Hello this is my first post asking for help. I am very new to 3D printing. If this is not the right place please help me by pointing to right direction.
My printer heats up to 215C as recommended. I start printing and it prints fine. As I keep printing the temperature drops and my hot end jams at around 185C.
Prusa i3 hot end is Makergear V3b version. Please help Thank you.

I think I found the problem, The fan sucking the air to cool the v3b groovemount caused the temp drop. When I put a piece of tape across the fan duct to limit the region of cooling to just the groovemount, the temperature hold. I'm guessing the heating is an open loop with no feedback to keep the temperature at specified temp.
