I have a issue with my 3d printer is over heating


How to solve the issue

That looked pretty terminal. Does the hotend fan not spin? Strip the whole thing down and inspect the PCB, though there isn’t much on there that has magic smoke in it. The hotend shouldn’t get that hot if the thermistor works, if it doesn’t then it should fail safe anyway. Cooked stepper motor?

Looking at the picture smoke is coming from around the hotend cooling fan. these are prone to failure. Can you confirm this fan is working, if not it may be the root of the problem.
