I'm using a 50 mm round disc mold, 12 cellsand depositing with a syringe from a Rev 2. It starts pulling away from the outside and movestowards the center. It leaves a spot, quite nice looking,in the center when I unmold them. I'd like to make that spot bigger.Any ideas would be much appreciated.

To have a larger spot you'll need less contraction of the finished piece. Less contraction means having more cocoa butter crystals and less fluid cocoa butter in the tempered chocolate prior to molding. You can push this pretty far, but you may need to increase the rate at which the pieces are cooled, or, due to the additional stable crystals, solidification may happen so quickly that the latent heat of crystallization that is released will not be able to be effectively removed, and you could end up with temper issues.In simple terms, create a "more tempered" chocolate prior to molding. It will me more viscous or "thicker." See how that works for you. Just be sure to have efficient cooling.

Two changes we made with the chocolate is that this time we winnowed the chocolate. This time we didn't use a blow dryer to melt the chocolate. Two improvements with the chocolate is that the melanger didn't get clogged this time and everyone put in work.
