(speed, flow rate, spacing, etc), then those regions need to be printed separately from the regular solid fill. Otherwise you would be extruding at 200 mm/s, 100% flow, but then expected to immediately slow down to 50 mm/s and potentially 120% flow in the same movement. The flow and speed cannot change this quickly, so the solution is to print these regions separately with the exact settings that you specify.
NO that is not the solution. the solution is for the software to PRINT that layer as one monolithic component and for it to IGNORE the settings that tell it NOT TO. that is the correct solution.
and no. it is not "we should change the settings" the coders "ALTERED" the behaviour of the software did not tell us this. we now have to "GUESS" why the software is behaving differently in a way it has never done before...... think about that for a moment.
first. there is zero reason for this "feature" to exist. it serve no valid function and "breaks" the software and second if there is a reason IT SHOULD ALERT the user hey this is going to cause a conflict. do you want to change this? and TELL the user what to change.
IF IT DOES have a place the software should be SMART enough to selectively apply the settings so as not to break the model.
