Since this month I one now one small 3d printer. Its a ["ender 2"](https://www.banggood.com/Ender-Ender-2-DIY-3D-Printer-Kit-1_75mm-0_4mm-Nozzle-150-150-200mm-Printing-Size-p-1134488.html) with
an build volume of 165x165x200mm. For my purposes this is more than enough since I
always could print larger parts with the [Toolbox e.V.](https://toolbox-bodensee.de/) Printers since I am member there.

The printer was pretty easy to assemble and took just about 2 hours of carfully reading and
assembling the parts.

Out of the box the printer was printing prefect. But since i did know that the printer from
Creality have disables safety features I installed the latest firmware from the [Marlin](http://marlinfw.org/) github repository.

There I changed the config parameters to my need and enabled the following options to lower the risk of fire caused by a printer failure.

``` c
#define THERMAL_PROTECTION_HOTENDS // Enable thermal protection for all extruders
#define THERMAL_PROTECTION_BED // Enable thermal protection for the heated bed
```

With this option enabled I Printed a benchy which came out perfectly. A benchy is a small boot which you can see in the lower picture. It has some structural parts which are though to print.
