The test article came out perfectly. So the new film is okay.
Once again, the translucent resin makes it difficult to see just what's going on with this tiny model. They are slots and holes and tiny probes. There a field of needless in increasing length and thinning diameters. They were all resolved correctly. The machine is capable of doing some very fine work. With this assurance, I've started printing the 567 head, only this time, I'm orienting it horizontally, with stouter supports. If that doesn't work, I'm going to attach directly to the plate with no supports. It's a long flat piece mainly in 2 dimensions without much of a z axis.
Wish me luck...
