Hi everybody, Im new and Im trying to understand how the difference between these 3 vars work! I tried to set the gap between nozzle (0.4mm) and bed at 0.1mm then If I print at layer height 0.2/0.3mm (Using Ultimaker Cura 3.5.1) the printer do the sound of "stuck" like if it is too close at the bed and filament stay stuck until get +Z. All my first layers are ugly! Should I put the flow under 100%? Thank you all
