This was caused because of the Raspberry Pi GPIO pins.

Motor is step motor Nema 17 200 steps 1.5 A 1.8 degree.

If you want to reduce the number of steps for a revolution, you can disable multi stepping on your drv8825.  Please also post a picture of the motor.

The only difference is drv8825 driver. All plastic parts are same printed from thingiverse piclop projects. The question we ask is for getting a complete turn of the table we need to enter 204800 instead of 6400 step in freelss. Our scanned image is not well. Is this can be related to steps? What can be the problem? Our electronic schema can be seen from the following image. Thank you in advance.

Can you tell us what should be the specification of the motor compatible with freelss or what are the properties of your nema motor?

We have completed the scanner but there is a problem. Our stepper motor does not turn properly. Maybe problem can be caused from the stepper motor. Our motor is Nema 17 200 step 1.5 A. For a whole turn we need to enter 204800 instead of 6400 step and we use DRV8825 instead of A4988.  What can be the problem?
