When should you use this tool?
Use it when you want to plan nozzle size, line width, layer height and speed as one system instead of tuning each parameter independently.

Nozzle, Layer & Speed Planner
Two separate jobs: build a sensible starting point from nozzle size and print goal, then check your own slicer values against layer-height geometry and volumetric flow.
Recommend a starting profile
A quick, technically grounded starting point. This is not a printer preset; it is a geometry and flow check.
Starting layer height0.20 mm
Starting line width0.44 mm
Flow-limited speed ceiling205 mm/s
Working ceiling with 15% headroom174 mm/s
Check your slicer values
This mode does not invent a profile. It only checks your values mathematically and geometrically.
Required flow18.00 mm³/s
Flow utilization100%
Theoretical flow ceiling200 mm/s
Flow headroom0%
What does “flow ceiling” mean?
The planner uses volumetric flow ≈ line width × layer height × speed. Rearranged: speed ≈ max volumetric flow ÷ (line width × layer height). This explains why the same 18 mm³/s can support a much higher linear speed at 0.20 mm layers than at 0.30 mm.
Practical rule: robust profiles usually benefit from some headroom below calibrated MVS. The planner therefore also shows a working ceiling with 15% reserve.
Miniatures: a 0.2 mm nozzle mainly improves XY detail. Extremely small layers mainly improve Z resolution; cooling, minimum layer time, acceleration and thin-feature handling can limit the print long before flow does.
Important: the displayed speed is only the theoretical limit imposed by the entered volumetric flow. It is not an outer-wall speed recommendation and does not guarantee that your machine can reach it. Acceleration, motion system, cooling, geometry, material and quality goals can limit you much earlier.
Tool guide
Nozzle, Layer & Speed Planner: when and how should you use it?
A useful result starts with the right question. These notes explain what the tool is designed for, how to interpret its output and where a calculation is intentionally only an approximation.
How to use it well
Choose nozzle and layer height first, then use a realistic line width and flow limit. Compare the resulting speed with motion, cooling and quality limits of the printer.
Limits & important notes
A mathematically possible speed does not guarantee clean surfaces. Acceleration, cooling, resonance, extrusion dynamics and geometry may become the real limit first.
Frequently asked questions
Why plan nozzle, layer and speed together?
Each one changes how much material must be extruded. A larger nozzle can reduce print time, but wide and tall lines quickly increase required hotend throughput.
Can a 0.6 mm nozzle print faster than 0.4 mm?
Yes on suitable parts because wider paths and taller layers reduce path count, as long as hotend and material can deliver the required flow.
Which matters more: max speed or Max Volumetric Speed?
For extrusion moves, volumetric flow is often the more practical limit. Small features and short moves can additionally be acceleration-limited.
Are the results a ready-made slicer profile?
No. The planner checks a physically sensible combination. Temperature, cooling, acceleration and material-specific settings still need calibration.
These tools provide guidance and calculations from your inputs. Safety-critical, electrical or highly loaded parts require additional verification.
