Hey guys. So I have a really goofy issue with a DIY LED set up. I mounted 72 stars split equally between 2 60" heatsinks. I used thermal paste and screws with plastic washers to mount the stars and wired everything in series to a Meanwell driver with 3 in 1 dimming. Before after triple checking everything I wired up a potentiometer to the dimming wires and powered it up. ALL GOOD. Now here's where it gets goofy. I mounted the fixture above my tank and desoldered the pot and soldered the leads from my 1-10 port off the Apex. I set up my ramp profiles and again triple checked everything. I power it up and only half the LEDs fire!!! So desolder the 1-10 and wire the pot back on and of course it fires all the LEDs no problem. I test the 1-10 port with a multimeter to make sure I was getting 10v and I was. I tried a different cable and 3 different ports on my Neptune. I'm at a complete loss for what to do next. Please help!!!!!
