Connect a PC via USB and start [Pronterface](http://www.pronterface.com) or Octoprint. Start a print and look at the console output. The error message is displayed here. There is no point in troubleshooting without looking at the message in the console. Therefore, this should always be the first step when an error occurs.

This is the [Thermal Runaway Protection](https://help.prusa3d.com/en/article/thermal-runaway-temperature-drops_2131) from Marlin, which struck in. Your nozzle or bed (heater 0 is the nozzle) has not reached or maintained the correct temperature in the given time. This leads to an error. The original Firmware did not have TRP and thus could not stop the printer. There are many reasons for such an error. Most of the time it is simply because someone forgot to set the original component cooler in the slicer to 70% (see above). At 100% it now cools too much and since it blows straight against the nozzle, the temperature drops too much, which looks like a failure for the printer. Another possibility could be a wobbly or defective thermistor or heating cartridge. It is also possible that the new [PID controller](https://en.wikipedia.org/wiki/PID_controller) heats the heater a little too carefully. This can be remedied by the PID tuning in the special menu. It also makes sense to install a silicone sock for the hotend, as this protects the nozzle from drafts.
>Knutwurst, why do you also make such a firmware? Aren't there so many already?
Because I haven't seen any that don't contain the stupid bugs, such as that it crashes if you have files with special characters on the SD card.

Your component fan is now running at full speed, which it didn't before. Simply set the speed in the slicer (e.g. Cura) to 70% and you have the old volume again. This modification is necessary if you want to replace the fan and many fans with the original duty cycle do not run or run poorly.

>Is your firmware better than others?
No. But certainly not worse either.
