I have a wave that does NOT have top side preheats. I have not worked with a machine like this in the past. The majority of my experience revolve around topside temps prior to entering the wave. Has anyone else worked with a process like this? What a

Yes it is "Print Front Limit" and "Print Rear Limit". Negative value extends the stroke, Depends on software version how useful it will be, as there are differing limits on how much you can extend the stroke. http://www.dekhead.com

We have multuiple pcb transport conveyors that use the 10mm wide flat green blets on either edge. Does anyone know of a kit to purchase where we could make our own or a company that supplies different sizes? Thanks
