Stepper driver warning: OTPW flag set
Hi All,
I have been getting this warning for stepper_z1 and stepper_z2 pop up anytime I activate my Z-motors.
"Stepper driver warning: OTPW flag set
The stepper driver 'stepper_z1' has triggered the OTPW flag and may stop working if it gets any hotter. This is an indication of an over temperature condition. This can be caused by a too high current. Please check the stepper driver settings and cooling."
Any thoughts on how to fix? I don't know how to change the current of the steppers.

You shouldn't need to, Rat-OS sets the current correctly. Do you have fans over your drivers?
