Build Your Own SLA/SLS

We are able to control the z-axis movements using the g-code commands manually. However, when we tried running the printing program after slicing the image, we faced two problems:
1) The projector does not project the sliced images of the part, while still projecting the calibration grid correctly.
2) The stepper motor does not move according to the g-code commands. The g-code has the stepper motor commands mentioned in it as per the sliced images, 'curing time' and 'holding time after each layer' but still it does not rotate.

Help! Thanks!

The system we're using includes a Sharp DLP projector and an Anaheim DPY50611 Stepper Motor

Here is the sample of our g-code:

The screen settings for the projector is attached as an image.

I got your point, but why does the projector not project the layer images?
