There was a problem hiding this comment.
Since there is logic to handle the sync issue in Tab.cpp, is there any reason to have this check here? It's not a desired behavior here

Can I check what's the status of this PR? |

Some more changes are in the works. I have added a printers from the company that hired me to make the changes "Ginger Additive". Here's our fork: https://github.com/gingeradditive/OrcaSlicer/tree/pellet-printer-implementation-rebased-onto-main Just going to rebase/merge with the current OrcaSlicer main on Monday. and raise a proper pull request |

Large format printers with print volumes in the order of 1m3 generally use pellets for printing. The overall tech is very similar to FDM printing. It is FDM printing, but instead of filaments, it uses pellets.
The difference here is that where filaments have a
filament_diameterthat is used to calculate the volume of filament ingested, pellets have a particularflow_coefficientthat is empirically devised for that particular pellet.We are translating the
flow_coefficientintofilament_diameterso that everything works just like it does already with very minor adjustments.filament_diameter = sqrt( (4 * flow_coefficient) / PI )sqrtjust makes the relationship betweenflow_coefficientand volume linear.This will allow a lot of accessibility for an increasing market of pellet 3d printers. Ginger additives, Colossus and CEAD being some of the leading names.
