Cooling

Enable Print Cooling

  • Enables the print cooling fans while printing. Purpose is to improve print quality on layers with short layer times and bridging/overhangs.

Fan Speed

  • The speed at which the print cooling fans spin (Based on percentage).
– Regular Fan Speed
    • The speed at which the fans spin before hitting the threshold. When a layer prints faster than the threshold, the fan speed gradually inclines towards the maximum fan speed.
– Maximum Fan Speed
    • The speed at which the fans spin on the minimum layer time. The fan speed gradually increases between the regular fan speed and the maximum fan speed when the threshold is hit.

Regular/Maximum Fan Speed Threshold

  • Layer time which sets the threshold between regular fan speed and maximum fan speed. Layers that print slower than this by default use regular fan speed whereas faster layers gradually increases towards maximum fan speed.

Initial Fan Speed

  • Speed at which the fans spin at start of print. In subsequent layers, the fan speed is gradually increased up to the layer corresponding with to Regular Fan Speed at Height.

Regular Fan Speed at Height

  • Height at which the fans spin on regular fan speed. At the layers below, the fan speed gradually increases from Initial Fan Speed to Regular Fan Speed.
Regular Fan Speed at Layer
      • Layer at which the fans spin on regular fan speed. If regular fan speed at height is set, this value is calculated and rounded to a whole number.

Minimum Layer Time

  • Minimum time spent in a layer. This forces the printer to slow down, to at least spend the time set here in one layer; allowing the printed material to cool down properly before printing the next layer. Layers may still take shorter than the minimal layer time if Lift Head is disabled and if the Minimum Speed would otherwise be violated.

Minimum Speed

  • The minimum print speed, despite slowing down due to the minimum layer time. When the printer would slow down too much, the pressure in the nozzle would be too low and result in bad print quality.

Lift Head

  • When minimum speed is hit because of minimum layer time, lift the head away from the print and wait the extra time until the minimum layer time is reached.
