| - | During various tests with different kind of filaments, some material would stick better | + | Did you ever try to turn on the left or right cooling fan at the Flashprint((The Slicer provided by Flashforge, currently at Version 5.8.7, [[https:// |

Further info can be found here: [[https:// |

| + | This long article is about getting the left cooling fan to work, starting reverse engineering with Ghidra and patching the firmware and much more. | ||

| + | So, I needed to verify if cool would only not spin at all. since these were hidden inside the printing enclosure and were hard to see. Furthermore, | ||

| So after spending more time on it, I found out that when printing from a file, both fans would actually work as expected. Measurements with an oscilloscope confirmed that for both fans, rotation speed was controlled with PWM (Something which did not work on a Creator Pro 2, for example.

| The main role of the Allwinner cpu, apart from providing a graphical user interface, is to prepare gcode commands from internal saved files and/or commands sent over the network to the printer and forward them to the motion controller. In the other direction, the motion controller sends data, like temperature information to the main cpu. This can be seen when connecting a serial cable to the corresponding RX/TX pins (J25) on the main board. | The main role of the Allwinner cpu, apart from providing a graphical user interface, is to prepare gcode commands from internal saved files and/or commands sent over the network to the printer and forward them to the motion controller.
