This repo contains information about my personal experience and configurations about the FlyingBear Ghost 5 3D Printer.
The firmware the printer ships with contains multiple errorous values as is explained in the video by drucktipps3D. The robin-nano35+cfg.txt file in this repository contains the fixes mentioned in the video.
The robin-nano35+cfg.txt also containes changes to the direction of the z-axis and extruders which are only needed when using TMC2208 stepper motor drivers for the Z axis and the extruder motor (see below).
My Ghost 5 came equipped with a TMC2208 driver for the X and Y axis respectively. Z and the extruder were using a basic A4988 driver which means the stepper motors are quite noisy.
Upgrading the Z axis and the extruder drivers to TMC2208s can solve this problem. However, this requires some hardware tweaking as can be seen in this guide.
By default, the 5020 fan the printhead comes equipped is wholy inadequat to cool the filament while extruding. Because the airflow is not directed at the nozzle, prints are prone to stringing and failing bridges.
An easy improvement is a simple fan duct which can be clipped on the fan and improves the quality noticeably. However, this is still not enough to successfully print with certain filaments. Next a completly new printhead was tryed.
