In what field/ work do you do , that you have access to such beautiful machines?

[@lavithhcm]

CNC

Announce the diameter doesn't actually have any effect on printing parameters directly. I can use a 0.4 mm nozzle and extrude out to 0.7 mm wide by setting it in my slicer.

[@lavithhcm]

it must have some effect behind the scene calculating how much and how fast to push out the filament to meet the demand you want. in your case 0.7mm width. if you print mid-air, (bridge) you never gonna get 0.7mm doesn't matter how hard you try to push the filament.
