Tonight while performing a test run, I saw a flickering issue on 2 universes when the lights went all white. I have the following setup: 1 * ECG-P12R About 50-55m of RGB strip (12v), spread over 4 channels (colour coded with heat shrink and electrical tape as White, Blue, Red and Black) 80 or so RGB modules (12v) About 300 pixel string lights (5v) (2 universes on the 5v power side) The P12R is wired with 5v power to power it up and for Universe 7-12. I have 2 * 12v power supplies connected too for Universe 1-6. The 1st PSU is cabled to the P12R and I have a few direct runs along the runs connected to the PSU's (injected power). To connect the 2nd PSU, I pulled the red out of the P12R from the Blue and White string and connected them to the 2nd PSU +, then connected the black from the first PSU to the 2nd (common ground). Last night I tested everything connected except the stuff connected to the 5v universes (basically they are converted sillouettes). This arvo, all I did different was to connect the sillouettes to the 5v universes. This flickering is happening on the 12v blue and white strings. Is this related at all? I haven't put the multimeter on the PSU's yet, so not sure if it's a load issue, however it seemes to run fine when everything was initially connected with just the 1 12v PSU, but it was getting warm when running 10 minutes of show. BTW, the P12R is running the latest firmware.
