About this model

Here you can find 2 simple "Heattower" to find the perfect temperature for your extruder and your used filament. One tower has a size of 20x20x50mm for 10 different temperatures the other 20x20x60mm for 12 different temperatures. Every 5mm you can see a pit to recognize the different layer temperatures. You have to set your slicing software that it change every 25 or 50 layers the temperature. It depends on your layer height. I use a layer height of 0.2mm so I change the temperature every 25 layers. I start at 235C° for PLA and decrease the temperature every 25 layers about 5C°. If you use S3D you can easy set these temperatur settings under the "Temperatur" tab. If you use another slicer you may have to change them direct in the gcode. Its important, that you print the heattower with the …
