Prints a tower in speed bands to find the highest print speed your printer holds without losing quality.
How to use it
Start a new, throwaway project and select your printer, filament and nozzle.
Run Plugins → Calibration → Speed Tower.
Set the speed range (default 30–180 mm/s), the number of bands (default 5) and the tower size.
Slice. In the preview, check the Speed view: a band that prints slower than engraved is limited by your hot end or motion settings, which is a result in itself.
Print and pick the fastest band before the first one that shows defects.
Reading the result
Ringing or ghosting after corners: acceleration or frame stiffness is the limit.
Thin, weak or gappy walls: the hot end cannot melt plastic fast enough.
Clean walls: the speed is usable.
Good to know
Each band uses a modifier volume that sets perimeter, infill and gap-fill speeds to the same value. This is the same mechanism Prusa's own Flow Tower uses.
Layer-time slowdown is turned off and cooling is fixed at 100 %, so cooling does not confound the comparison. Your maximum volumetric flow stays active as a safety limit.
These filament changes are not restored. Use a throwaway project.
Speeds are requested, not guaranteed: on short walls the head may never reach them. A larger tower gives it more room.
Changes in this version
Fixes the speed modifier bands, which could be offset in height from the tower bands they belong to.
