At long last, I found the problem with the infrared noise. I assumed that the black resin wouldn't let any light through, but it allowed IR to pass, albeit attenuated. The picture below is an infrared flashlight below a 6mm thick printed piece. Now, I'll have to change the infrared aerial design.
IR can penetrate printer resin
I thought about a complicated aerial that used M2 bolt cross members and foil-shielded LED nodes, but I decided to replace the bare IR receiver with the shielded version. Remodeling shouldn't increase the size dramatically. In this revision more the receiver will be exposed.
IR aerial with a larger receiver socket
I installed the IR receiver smoothly and added five wires. This time, I learned from the previous experience, and the wiring was tidier, and the conductors coming out felt more secure.
IR aerial with a shielded receiver
I broke three of my finger rods when I dropped the unit, so I printed replacements and wired them up. This time, I took extra care to cut copper tape strips that wouldn't create any seam-lines on the bottom of the finger rod because it should contact the Velostat uniformly.
Four finger rods, hot off the press
I decided to add my updated aerial to the project rather than replacing the old one. This way, I can compare between the old and new. Since I'm still figuring out this arrangement, it seems like the most logical approach.
Two IR aerials installed
I did some program updates, but that uncovered problems with the hardware. I forgot to add pull-down resistors on the finger rods, and the other issue is that I get readings from a pressure sensor when I try to read my infrared receiver.
