Ofc the way s3d set speeds it's a bit different but it's just a simple % calculation.Īlso change z speed to 20-25mm/s and travel speed to 150-180 since s3d has a very horrible standard settings. This way you can copy your speeds settings to s3d easier. Go to preferences menu on s3d and change the setting that shows speeds from mm/m to mm/s. Doing it progressively helps the PID keep the heat constant without big drops in temp that can affect print quality. Because if you print many small objects the fan really close to the bed might kill adhesion.Īlso it's a good idea to avoid a full blast, because the air will hit the hotend and will lower the temp 1-2C. If you use glue/hairspray on the bed, or the object it's just 1 on the center of the bed, you should be able set a higher fan sooner.Īlso check that bridging has a specific fan speed (if you activate the option) so you can set a higher fan for that.

But for hard overhagns I go slow at layer 2 and increase it. I use to set a minimum fan at layer 4-7 and then I ramp up 10-20% each 5-10 layers. S3D fans go 'on' at specific layer number, so you need to remember that if you change the print layer height (resolution) the fans will go on sooner or later. But there's no perfect answer and sometimes depends on what you print.
