I am new to saber building (fairly competent on electronics an computing). I have assembled the saber to the point that the color extender is necessary to complete. I am using the CF7.5 with a tri rebel led. I am perplexed with a problem on the bank 2 sound font, all of the other 11 fonts light the high power led on power on an work properly with the FOC. With bank 2(crystal focus sound bank) the high power led only lights during a FOC. I edited the config.txt file to assure the led=700,0,0,0 was correct an did a line by line comparison with the other banks config.txt an could find nothing that should fail the led. I then downloaded entire CF7.5 full load from plecter labs website unzipped an loaded bank 2 directory to the sd card with no change in results. I am confident the hardware is sound as I can connect any of the 3 leds an they will function properly on any of the other 11 fonts. Any input on what might be the cause would be appreciated!!!
