This. Finger oils are the enemy. If you've never washed the bed with soap and water, it usually fixes adhesion issues on a properly leveled machine.

Update: With some experimentation, I think I figured out what was going on. I had an extra 10K resistor in the circuit which wasn't necessary. With both the resistor and the potentiometer in the circuit, I was only able to light up the red channel with the pot turned fully clockwise. Without the extra resistor, a full turn of the pot lit up all the channels and gave me the white coloration I was wanting. The green and blue channels weren't lighting up because of the excessive resistence and the fact that they obviously power up at different levels. I was making the poor assumption that all of the LEDs would power on at the same time despite the fact that green and blue light require different energy levels.
Yeah, I'm just planning on using small lengths of the remaining strip in some miscellaneous projects needing lighting. I hadn't tried connecting multiple potentiometers for simplicity's sake, so I just have everything connected to one pot. Should that work?
Agreed. I think a general 3D printing community should be all inclusive of types of 3D printing. You can always make a community focused on FDM vs SLA, Etc.
While not for 3D printing specifically, Andrew Price's donut tutorial on YouTube is a great primer for learning to use Blender and all is basic functions.
A little aqua net hairspray will do the trick too.
