The sg90 steering gear cannot be moved

Controller Board

ESP-WROOM-32

Machine Description

Plan to use a steering gear instead of the Z axis to make a pen lifting tool, now the stepper motor can be driven normally, the steering gear has no response

Input Circuits

No response

What command did you send to test? The Z axis does not have soft limits enabled, but the range is -5 to 0 mm. Is it possible that the command you are testing with outside the range?

If you try to touch the servo, is it engaged/enabled at all times?
