I’d like to share my learning process, which is similar to your experience. I used to be an application and hardware engineer at Revvity, and I recently switched to a new job that requires the use of VENUS/EVO/Bravo and other scheduling software.
I spent about two weeks first going through the VENUS Programmer Manual to get a preliminary understanding of the general logic and basic concepts of the VENUS software, such as Labware, Liquid Class, Deck Layout, and Sequence. Actually, these concepts are quite similar, though different software has its own specific details. You need to pay attention to these differences—for example, certain parameters related to Labware are particularly important in section 5.5.3 of the VENUS Programmer Manual.
And this thread will help you to understannd how the VENUS software worked. Understanding the 6 main files in VENUS - Hamilton (Venus) - Lab Automation Forums
Then I found Chapter 12 of the manual, which contains some basic demo methods that guide you step by step in creating some fundamental methods. This helps reinforce the related concepts. Of course, there are some errors in this chapter, but it’s still very useful.
I think this might be helpful to you. Feel free to email me(yinruping@126.com) if you have any questions.
