The retraction length on tool change is the length of plastic reverse movement in a feeder. Choose maximum length, taking into account the fact that plastic won’t be fed into this tool for a long time and it is necessary to prevent plastic leakings due to gravity.
The retraction length is the length of plastic reverse movement in a feeder. Choose long enough length to stop pressure onto plastic in an extruder chamber. Keep in mind that during retract, the extruder stays still, so the longer retract, the longer it stays without movement, which can lead to part melting by the extruder, and leakings for runny plastics.
Choose the fan speed low enough for better adhesion to a bed and to prevent geometry changes due to bed heating.
The first layers fan speed height is the height below which cooling rules are special. Choose a minimum but sufficient height so a part is securely glued to a bed and part geometry won’t lose its geometry by bed heating.
The maximum fan speed is the fan speed for cooling which is used when layer time is less than minimal layer printing time (specified in settings). Indicated as percentage. Choose maximum speed to have no form meltings and geometry distorsions.
The regular fan speed is the fan speed for cooling while all printing process except printing first layers. Indicated as percentage. Choose high enough for saving part geometry undisturbed, but not too high for layers start losing good adhesion beetwen themselves.
Enable print cooling is the flag of fan on/off for cooling extruders. For best results, turn on cooling with any print.
The build plate temperature on first layers is the table’s temperature which is kept constant only on first layers below height defined in settings. It should be high enough for a part immediately and securely glues to a table.
The extruder temperature on first layers is the extruder printing temperature which is kept constant only on first layers – below height defined in settings.
The first layers temperatures height is the height below which extruders and a table have special heating rules.
