Hey there. I've found myself often highly modifying the infill angles/design/etc. In order to make some bigger prints that are properly supported, and yet require minimal material. IE: I'm often printing large 6"x8"x4" size models but where I only want to use 200g of material cause I'm making a ton of them. So very careful tweaking of the infill settings, and I can manage to come up with a system that has infill supporting any bits I really need supported.
All the infill settings and printing of the infill, is based on 'centered on the build plate' pattern. If you move your model an inch to the right, suddenly the infill is all different since the infill pattern exists separate from your model.
This means that if I carefull design the infill to work for my model, I can then only print one at a time, centered in the build plate. If I try to print 2-3 at once. It all fails since the infill pattern isn't doing what I need.
I'd love an option for 'center infill pattern per model' vs 'center infill pattern on build plate'. So that I could design my infill, but then put multiple models down, and know that each one will be printed exactly the same.
