Max motor current question.

  • Hello,

    While editing my config.g to lower the current at my Z motor to 650mA from 750mA due to a typo i set it to 7650mA.. Of course the moment it started printing i heard a weird noise after the first retraction and i immediately checked the motor, felt it was hot and terminated everything.

    Now i corrected the current setting, let it cool and start printing again. At the moment everything seems normal.

    My question is, is there a possibility for anything on the board to be damaged by this? Or is any kind of overcurrent protection to prevent really high values?


  • the tmc drivers have in build overheating protection and will shut down when they get too hot.

  • Then i am good i guess.

    Thanks for the quick response!
