For direct control we have such option but if you wired drivers to RAMPS, you should see if it support such feature or not.

I am directly control from RaspberryPi 2 to L297 The signal latch as high after a sequence of step from the clock. It cause the driver to set high to gate of the driver. Can you advice me where I can set up such option ?

You should wire enable pin, and enable it on setup page.

I did but the motor stay enable after click on one of the option in "z-calibration". The clock signal stay high instead of low after performing the steps. Also, the signal only work when I click to Top from z-calibration option and there is no signal when I click Floor.

I didn’t test on any 3D print yet. I connected to L297 diver and check the reults in the oscilloscope. The motor move into one direction when I click Top. But, there’s no signal when I click floor. And Because the nanodlp latch on high after operate steps that cause 4 half bridge to be activated for L297 and cause short circuit.
