How far are your light units away from your printing frame? How do you support them? Hope that makes sense. I currently just use the unit sitting on the table, so there's not much distance between the frame and the bulbs. I was going through the thread about the Dmax on COT 320 and saw that people were using 10 and more minutes for their prints and was just wondering. I do my printing in the living room and with three cats in the house, I have to block the light so the cats don't stare at it.
