Retraction Calibration Tower

Generate a retraction test tower that actually runs on your printer. Upload a real slicer g-code for your machine — we reuse its start/end sequence and settings verbatim, then build the tower in between. Everything runs in your browser; nothing is uploaded.

Use a real PrusaSlicer / Prusa-family export for your printer (e.g. a sliced test cube). We read its start/end g-code and settings.

Retraction sweep

Distance varies around the perimeter; speed varies up the height.

Start retraction distance(mm)Distance at the first (origin) corner.Retraction increment(mm)Added per station (16 stations).Start retraction speed(mm/s)Speed for the bottom band.Retraction speed increment(mm/s)Added per test band.

Temperature

Cooling

Fan speed(0–255)255 = 100%.Fan increment(0–255)Per test band.

Test bands

Layers per test × number of tests = tower height in layers.
