Extruder Type Direct Drive Bowden Most modern printers are Direct Drive. Bowden needs more distance. Material PLA PETG TPU (flex) ABS/ASA Nylon Some materials string more and prefer different speeds. Hotend Liner All-metal PTFE-lined PTFE-lined hotends usually prefer shorter distances. Nozzle Size (mm) Print Temp (°C) Higher temp often increases stringing. Travel Speed (mm/s) Faster travels often reduce stringing.

Distance Range (mm)

Direct drive usually 0.2–1.2mm. Bowden often 2–6mm. Distance Step (mm) Speed Range (mm/s)

Most setups tune well between 20–60mm/s. Speed Step (mm/s)
