Check out my DSLR laser spot dissection thread here for information on getting usable laser spot pics. Just a normal single picture is not enough with any camera. The more interesting thing here is you have not had laser flare issues so far so you likely don’t have a particularly bad spot. IF this is a laser flare problem it is a likely a different manifestation of the problem caused by lots of closely packed items and supports. I would be interested how this print prints on other Form1+ printers, to see how common the problem is. It could explain some other artifacts that happen under certain circumstances.
