Change to prescription lenses

The edged prescription lenses are positioned and fastened on the second mounting stage. The horizontal axis line was drawn before grinding and is now used to find the right position, parallel with lines on the paper beneath the PVC pad.

Now attach the mounting stage with the prescription lenses onto the X-Y table and move the Y-axis back to 0.00 by using the Y Dial. Now move the lens mounting stage so that the very tip of the drill is at the very front edge of the rim of the lens. Reset the X-axis to 0.00 with the reset button.

Now you have reached the same position you had when starting with the demo lenses. The digital display shows 0.00 for both axis.
