8825 stepper allways on

I am running the 8825 drivers on a CNC shield, on a arduino UNO clone, running GRBL v0.9i, when I first started setting things up and testing my steppers they would Idle, now no mater what I have the idle delay in GRBL set to, the steppers allways energized, I have reloaded GRBL and tried a different version, and tried the CNC shield on a different arduino, but no change, could the 8825 be damaged to cause this, but still operate normally ? or any other ideas :frowning:



I am not familiar with how GRBL uses the enable pin on the DRV8825 stepper motor driver. Could you try disconnecting the enable pin from your controller and pulling the pin low and high to see if that enables and disables the driver?
