Extruder motor overheating
After running for about two hours, the motor gets too hot to touch. If I had to estimate, it's somewhere between 80 and 100 degrees. I'm concerned for the longevity of the motor and did not find a potentiometer near the plugin spot on the board.
It is a MK3S+ that I got near the start of March
They do get hot. When I close the enclosure door, even hotter. There are some mods you can do that add a wrap around fan across the motor - but they add a lot of mass to the print head, which is not great for your print quality...
