You didn't have to handle a pan, but you did have to:
1.put a case in the press,
2.raise the ram,
3.plug the funnel,
4.remove the funnel plug,
5.lower the ram,
6.repeat
Other wise, you would:
1.place a pan on the scale,
2.pick up the charged pan
3.dump powder into funnel setting on a case while in a rack
4.move funnel to next case
5.repeat
You added all this complexity, with potential issues, for 1 additional step, and it's still not a Prometheus.
