  @teastain

  Thank you for your help.

  But I doubt that the Bala2 source code (Bala2.ino) in the Github does not equal to preloaded software in Bala2fire product.

  So first of all I need to extract the current binary content from Flash and EEPROM of Bala2fire, and save it to Windows file in case it will be necessary to restore the initial state in the future.

  I investigated furthermore and I studied "esptool" can extract binary content from Flash memory (maybe also EEPROM) of M5Stack fire to Windows file, but I would like to know that the following process is correct or not for savIng and restoration full of binary content.

  To read from 0x00000 to x400000 Flash memory content and
  save it to Windows file (e.g. file name image4M.bin) by using
  "esptool"

  To write from 0x00000 to x400000 Flash memory content with
  image4M.bin

  Regarding 4M, I think initial Bala2fire uses at most 4M byte Flash for preloaded software.

  Thank you in advance.

  Problem:

  Der Schrittmotor funktioniert nur korrekt in der Z-Achse bei normalen (langsamen) Drehgeschwindigkeiten.
  Beim Versuch, die X- und Y-Achsen zu verwenden, funktioniert der Motor nur, wenn ich die Vorschubgeschwindigkeiten auf das 10-fache oder höher erhöhe.
  Wenn ich versuche, die Adresse auf 0x71 zu ändern, wird das Modul nicht erkannt.

  Hello @Olbi77

  if you want to stay with UIFlow1 you can use the following I2C blocks to turn external 5 V output on and off:
