The heating plate is powered over a solid state relais. This solid state relais is controled by the cotroller board.
The problem of the heating plate is that in the core the temperature is much higher than at the edge.

Conclusion
In my opinion the biggest problem of the printer are the stepper driver DRV8825 because they are realy loud and have a realy bad step accuracy.
Good on the printer ist the huge building space and the possibility to upgrade the printer to a better one.
Upgrade
How the printer can be upgraded will come soon!
Some points will be:
- Enclosure
- Advanced motor driver
- OctoPrint
