Mainboard for Anycubic Neptune 4 / 4 Pro 3D Printer (TL4970 / TL4972 Ribbon Cable)

Screen's blank. Fan's dead. You're staring at a $2,000 machine that won't boot, and the last thing you need is a six-week wait from an overseas marketplace.

This is the direct-replacement mainboard for your Anycubic Neptune 4 or 4 Pro. It suits both TL4970 and TL4972 ribbon cable versions, so check which type you have before you order and you're swapping boards in one sitting.

No re-flashing. No compatibility roulette. Pull the old board, seat this one, power up, print. Sorted
