Print fan is not spinning
Before we start checking your Print fan, power down and unplug your USB cable if connected. Open the electronics covering and examine the MK2/MK2S miniRAMBo electronics wiring or MK3 EINSY miniRAMBo electronics wiring.
Make sure that the fan is:
- Plugged into the right location
- Plugged in with the proper connector orientation
- Plugged in completely and making good electric contact
You can easily test the print fan function from the LCD menu Settings - Temperature - Fan speed. Always test with at-least 50% power. When you select the speed, confirm by pressing the knob.
When the print fan should actually spin up
Print fan is never used during the first layer of any material. From second layer up, it depends on the material profile selected in the slicing software. For example with PLA, print fan is running at 100% all the time until the print finishes. For ABS, the fan is turned off by default in our print settings.
