Hello Robert,
I had the same problem as Julion Hornos, that the stepper just jerked. Perhaps it should be added to the otherwise really excellent instructions that the cable colors for the motor windings specified there are not standardized. I had A1 red, A2 blue, B1 green, B2 black.
In the config.h there is a separate DRVBRD for 8825 for stripboard. Is there a difference?

  Is this the 3 bpards mentioned in config.h
  
  #define DRVBRD A4998_M_MT_F_BT //#define DRVBRD A4988_MT
  
  Looking in the file myBoardDefs.h
  Search for A4998_M_MT_F_BT
  
  and I get this info
  
  // myFP2_A4998 supports #define A4998_M_MT_F_BT 100 // A4998_M_MT_F_BT PCB. BT.BUZ.LEDs.LCD.OLED.HPSW.SPWR.TMP #define A4988_MT 101 // A4988_MT Stripboard, BUZ.LEDs.TMP
  
  Regards Robert

Hallo Ralf.
Ich kann leider nichts zu Deinem Thema beitragen....
Aber kannst Du die Windows-Aplication bei dir installieren?
Ich habe leider die in meinem Chat beschriebenen Probleme. Daher kann ich den Rotator nicht benutzen.
Wäre suoer, wenn Du mir antworten könntest.
Danke und Gruß
Klaus-P.
