Temperature tower maker

A temperature tower prints the same small test at a range of nozzle temperatures, one on top of another, so you can see which one gives the cleanest bridges, overhangs and surfaces for a filament.

Temperatures Filament

Bottom (hottest) °C Top (coolest) °C Step °C

9 levels, from 230 °C at the bottom to 190 °C at the top. Hotter is at the bottom because the printer starts hot and cools as the tower grows.

Changing temperature as it prints

The model only carries the labels; your slicer has to change the temperature at each level. Set the filament temperature to 230 °C, then change it at these heights:

From height	Temperature
Start	230 °C
11 mm	225 °C
21 mm	220 °C
31 mm	215 °C
41 mm	210 °C
51 mm	205 °C
61 mm	200 °C
71 mm	195 °C
81 mm	190 °C

{if layer_z >= 81}M104 S190
{elsif layer_z >= 71}M104 S195
{elsif layer_z >= 61}M104 S200
{elsif layer_z >= 51}M104 S205
{elsif layer_z >= 41}M104 S210
{elsif layer_z >= 31}M104 S215
{elsif layer_z >= 21}M104 S220
{elsif layer_z >= 11}M104 S225
{endif}

Paste this into the printer's custom G-code under “Before layer change”, then remove it once the tower is done. In Cura, use the “ChangeAtZ” post-processing script with the heights above.
