End of break

After a long winter break, I have started to work on the project again. I have mounted the lens on the printer, however, the lens is with 6kg rather heavy and the counter weights amount with 30kg quite a lot. So a lighter lens is more favourable. I have ordered a new Fresnel lens from Japan with 1.40×1.05m, which is double the area than the previous lens! It will arrive in the coming days. More to follow.
