Creality K1 Error 2298: Controller Has Powered Off

Creality K1 error 2298 means a controller’s configuration could not be updated because it has powered off. That wording is more specific than the usual connection complaints: the printer is not saying it cannot reach the controller, it is saying the controller has no power. Start at the supply, not at the data wiring.
It is rare for a K1 message to point this precisely, and the precision is worth using.
Where to buy
Inspect the power path, unplugged
With the machine off at the wall, follow power to the controller named in the message. Look for discolouration, a browned pad, insulation darkened near a terminal, or a connector that feels loose. Heat marks at a power joint mean resistance, and resistance means it will get worse.
Then the supply itself
A power supply that sags under load lets a controller brown out and shut down when the bed heater draws current. The tell is a fault that appears during heat-up rather than at idle. Plug the printer directly into a wall socket rather than a long extension lead before suspecting hardware.
Then the controller’s own protection
Boards shut down when they detect something wrong: overcurrent, overheating, or a supply outside range. A controller that powers itself off repeatedly is protecting itself from something, and finding that something matters more than restoring power.
How Creality K1 error 2298 differs from its siblings
A controller that is closed rather than unpowered is 2000. One that is powered and will not accept configuration is 2299. A failed attempt to restart one is 2295. Reading which you have saves opening the wrong part of the machine.
If it only happens on long prints
Then heat is involved. A supply working at its limit in a warm enclosure delivers less than it does cold, and the chamber warms everything below it — the board temperature version of that story is 2512.
Creality K1 Error 2298 FAQ
Is the controller damaged?
Not necessarily. Powering off is often protection rather than failure.
Could a loose data cable cause this?
It would normally produce a connection message instead. This wording points at power.
Should I replace the power supply?
Only after checking the wall socket, the lead and the connectors. Those are free and account for many of these.
Why only when the bed heats?
Because that is the largest current draw in the machine, and it is when a marginal supply shows itself.
