Anet A8 fan/extruder issue.

[Roberts_Clif]

Are you printing using USB cable or the SD Card.

SD card should be a 2GB SD Card. A-Net A8 SD cards should be formatted to Fat 16 using SD Formatter.

"Was informed that in some cases the supplied A-Net A8 SD card was not compatible with the Controller."
Most of us have 2GB SD cards everywhere could not hurt to try a different SD Card formatted with SD Formatter.

I'm using a Samsung 16gb micro sd card that's been working fine. I never could get the included 8gb card to work right. It works in other devices but no matter how I format it the printer won't recognize it.
