*I search c code or arduino code to control the variation of the line width of an cnc airbrush in such a way that it traces the outline with a thin line and filling the pattern is made with thick line
*airbrush is controled by stepper motor as 4th axe
*line width is controlled by distance (z axe) and flow of paint
*please I want to understand the code because I want to integrate it in 3d powder printer
*my project is a 3d powder printer as fabathome but instead the syringe I want to use an airbrush and hopper system to dispense powder
