Heating/cooling rate (C/sec)
This parameter is needed when using active temperature
control. It tells IceSL how fast an extruder is able to
cool down and heat. Most often, cooling is faster than
heating so use the slower of both. Heating is often
impacted by room temperature: you may want to
lower this value in cool environments.
If you notice a pause after an extruder swap, lower
this value.
