Step2 after changing to 330Ohm is like this: fine
Issue 2:
if you got this or this with 90degrees and you use a external PSU (MOTM,dotcom header)
AND you have the internal psu parts soldered, remove the internal powersupply parts (its only need to extract both LM317, D1,D2,D3,D4,D5, R1, R6, on board 2)
or you get this on Step 2.. attention to bottom
