lancehedrick I know found the back panel loose we put a new screw in it.
The particular gear pump used in the prototype is a pig to prime. I had the same issue this morning, but we went underneath to the transformer and reversed the connections there without having to open the case.
The production machine will have a rotary pump which won’t have any problems priming like that particular gear pump does.
P.S. I think the screws gone forever. 🤣
