BFB's already-assembled inexpensive 3D printer has now become the BFB 3000 Plus. The new version is very similar to the original BFB 3000, but has several enhancements.
Our understanding is that the Plus's improvements focus on two aspects: simplifying ease of use and machine quality. The machine's print bed is easier to adjust and numerous mechanicals have been upgraded to ensure a more reliable device.
The other improvement is software, namely a significantly upgraded Axon 2. Currently in beta test, the still-Windows-only software focuses on streamlining your printing workflow by bringing forward the most commonly used functions and hiding those less used. We're hoping to test Axon 2 soon and report more details.
