New Firmware
In order to properly the new BMG extruder some small adjustments to the firmware are necessary. The extruder is using a 3:1 gearing ratio, therefor the E-Step is adjusted to properly extrude the right amount of filament. Z-Max is lowered to avoid the X-Axis crashing into the printer. The new total height of the print area is 385 mm.
This guide shows how to flash a new firmware using Creality Slicer.
