Ask anything about the Flashforge Adventurer 3 3D Printer

[Perot]

With my previous 3D printer I have been using the Prusa Slicer (which is derived from Slic3r). Unfortunately the Flashprint slicer lacks some of the features of the Prusa, and the Adventurer 3 does not recognize the .gx files from Prusa although the gcodes seem to be correct.
I finally found out that the Adventurer 3 requires the binary data at the start of the gcode to show a small image of the object to be printed.

Has anybody found a solution to overcome this problem? To insert some binary code into the Prusa .gx file does not work, and although Flashprint can read (its own) .gx files it does not recognize the Prusa .gx files anyway.
How can the Adventurer 3 firmware or Flashprint be modified to ignore the binary representation of the object - or is there another solution?

Addendum:
Flashprint accepts files without the binary image of the object. Cura can generate regular .g-files that do not contain the image.
