| After lots of years with Panasert machines, I am starting to need to learn again. | 1. For the AP-20 can you retrofit 3D vision? Would you bother? | 2. Also for the AP, can you use 20x20 DEK screens with an adapter? | | Thanks to all you MPM expe

This may sound like a stupid question but keep in mind I am very new at this and most of the training I have recieved has been from operation manuals and this forum (thanks to all). Our purchasing agent (new hire) is ordering a stencil for the first
