4 . Remove the test print from the print pad .
NOTE: For more information, refer to the section titled
5 . Turn the test print over and inspect the printing grain of first (bottom) layer. When the gap is optimal, the bottom of the print should
appear smooth and the lines should be very light and tightly fused together .
Correct Gap
The gap is correct when the bottom of the print appears smooth and the lines are tightly fused together .
Gap Is Too Large
If the lines are more prominent (see the illustration below) and not tightly fused, the gap is too large . Calibrate your printer again .
When the gap is too large, the first layer may begin to fray when removing the print from the print pad.
Gap Is Too Narrow
When the gap is too narrow, the part may be very difficult to remove from the print pad. In addition, the bottom layers may break off
from the rest of the part while removing it. The bottom of the first layer will appear very smooth and shiny with almost no visible lines.
NOTE: If the bottom of the part appears shiny, make sure all glue has been removed and then reinspect it .
