My FBC digital displays simmers, all of them and at the same time and rate. So I’m sure, well maybe it is a power conditioning problem, one of my many weak areas.
Anyone got any ideas how to fix this?

Just spent 2 best part of 2 weeks trying to sort much the same with Medusa. If ALL of them are doing it then i'd start by looking at J1 on the MPU, try reseating the connector, then reflow the solder on it, if that doesn't do it, then replace or reseat U11 and finally replace the J1 connector. Unlikely to be a power issue in my opinion.

Went to check out my machine as described, but right now the shimmering has stopped. Thought best not to do anything until the problem reappears.

Well it started flickering again, so I tried exercise J1 and that seems to have fixed it. Thanks for that epotech.
