@3D_Laser No burn mark at all, even right up to the nozzle with the wrong lens in.
It however dose mark (burn through tape) without the lens installed, and with the old lens in…so think I have a problem with the lens other then it just being totally the wrong focal length.
Have ordered another one in the right focal lenth, but its going to take a while to get here as I could’t find anyone selling the right lens here in the UK, so ordered from China (would have liked to try out some LightObjects stuff, but their shipping is ridiculously height to the UK)
Pigeon, I would be willing to let you order one and have it sent to me in Niagara Falls, then as son as I get it, ship it to you for about $5-$7 Don’t know if this would help or not, just thought I would offer.
