Coming from a Cura world, printing multiple objects sequentially comes as second-nature to me. In Cura, included in the printer parameters are static items defining the size of the print head and clearance. Strangely enough these don't tend to change from job-to-job very often. The default setting is to print sequentially unless the height limits are breached - otherwise this sequential object "just works" in Cura - as soon as you add multiple objects to a print job it defaults to sequential printing which is really nice. Sometimes it's the little things that make you smile - how Cura will add new objects arranged to print sequentially automatically.
However I am baffled by how you configure a sequential objects print job in Simplify3D ... it seems anything but simple. Multiple objects get dumped one on top of the other (which is pretty useless - why not "Center and Arrange" every time new objects are added? Does anybody want to actually have all objects piled up on top of each other?)
Then to actually configure Simplify3D to print sequentially, even when all objects have the same process, it seems I have to create one process for each item that I want to print sequentially? What if I have a dozen objects, I have to create separate processes for each one? Why? Even after that, I'm prompted to specifically enable sequential printing every time I go to print - and even then I have to manually enter the print head clearance every time - and it starts from 0.0, rather than being a static configurable parameter for my printer (seriously? who needs to change this for every print job?).
Even then, the configurable parameters for clearance in Simplify3D are ... one. Only one - height. Because it doesn't have parameters for X / Y clearance, there is not even a possibility of automatic placement of items to provide adequate clearance for sequential printing like there is in Cura.
This seems like a massive deficiency in the UI design and functionality within Simplify3D, and it's going to continue to annoy me, when Cura's free and open source implementation of sequential object printing is so much more advanced.
Please do a full implementation of sequential object printing!
