105 macros:
106 startup_line0: $HY&G1Y3F600&G4P2&$HX&G1X10Y10F600
107 startup_line1: G4P2&$SD/Run=RMRRF_V1_Spins.gcode
I added a G4 to the second line too. That is working too.
The WLED is also defaulting to the rainbow preset. So I should be able to just turn them both on and they will start impressing.
