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.
Since I had the Fresnel lens, since quite a while laying around, finally, the mechanical and electronic parts for SolarBot One have arrived from Germany and Spain. I plugged the mechanical parts together, and the aluminium profiles are great. Though I noticed already some possible improvement. I choose 2cm thickness, which will work, but, thicker is better, probably 2.5cm. The lens mount needs some stabilisation with steel plates. And I decided to cut the Fresnel lens in half, then I can fit everything conveniently in a 1×0.5m bag for strollers. Some pictures will follow!
Now, next comes the more challenging parts: the electronics. I need to mount the steppers properly and the z-axis for the sandbox is a bit tricky one.
The concept of the SolarBot Six, which will be the final sigloo printer, has been completed.
The website has been launched and is now online. Facebook page is also online, you can find it under facebook.com/solarigloo.
