Herman, Before I get into this I would like to know something. What machine takes the longest to change over? That should be equal to your change over time. If it is not one of your pick and place machines this is all beside the point. I am not sure

I have 5 of these machines. What software version are you running. 24 inch frames will interfere with the USC. The solvent bar will ride on the stencil frame. This will not allow for a pre-load on the foil. 1. Adaptors suck! 2. Adaptors suck! 3
