I put my own journey here. Replacing the motor didn’t fix it. Replacing the hotend circuit board made it at least make noises.
Think I’d heard of similar problems due to the wiring bundle - perhaps a crushed or broken wire, or loose/bad connector. Worth a double-check and close inspection.

exact same problem. gears are fine I can manually push filament through if I take everything apart and even removing the cfs no issues. My gear even turn left to right but as soon as I extrude or manually extrude through the interface it locks up doing nothing. I’ve done dozens of calibrations, power downs, dis assembled, firmware rollback and re installs. Support asks if filament is jammed in extruder or nozzle…. I’m like you think I would do all those other things and not also check that a dozen times? Something is wrong with support it takes them a week to respond and its like I’m talking to a bot.
I am having this exact problem. Will extrude if I push it through manually and if I use the X up or down it moves. If I hit the extrude or retract button on the printer it just locks up spinning in that mode. If I print something it sits at 0% and does not move again until I power cycle. There are no clogs if I heat it up I can manually push the filament through.
Had the same a year ago, open the extruder and film the gears when you press on the print screen to extrude dont forget to film also the temp. Then send it to support . Then the wil send you a form where the can send the motor. The also sell them on AliExpress.
I am here in April 2026 to report the same issue on my K2 Plus. The extruder motor simply disengages and stops. It all started with error FO0528. Initially, I thought it was a defective CFS, but even without it, the machine keeps printing without extruding. I’ve already contacted Creality support, and they are sending me a new motor. However, I noticed the printer started showing other bed-reading errors. I decided to disassemble and measure the cable. Bingo: I found 3 thin wires (yellow/green, purple, and gray) with a bad connection, almost snapping. Looking closer, I found a break in the cable near the print head. I soldered the 3 damaged wires and reassembled the entire unit. Unfortunately, it didn’t solve the issue; the error persists, and I am now just waiting for the new motor to arrive.
Using a thermal camera, I noticed the motor exceeds 75°C when printing ABS or ASA. I suspect this is a degradation of the motor and circuit components, perhaps something Creality did not efficiently foresee before launch.
The printer has 1,000 hours of use, always running ABS. I’ve tried changing the firmware several times (from the oldest to the latest) and switched to OrcaSlicer, but without success.
I suspected the motor was exerting too much force, so I increased the ABS printing temperature to 290°C. It seemed to help at first, but the problem soon returned. Everything indicates it is a hardware defect, a heat-induced wear on the components (the motor’s magnets suffer at these temperatures).
My last hope now is to replace the complete hotend, extruder, motor, and main cable. If none of this works, I will look for a way to disable this motor deactivation directly in the firmware.
I know it has been a long time since the last post in this forum. I would like to know if anyone has reached a conclusion, as Creality itself hasn’t solved this case yet.
Discovered that the extruder motor is always at 100% power, so it was already hot at the beginning of a print. Now I always press “Motors off” after a print. Given hours to cool, print success went up for me. Somewhere here a year ago, a user piped an air hose to the extruder motor, and blowed cool air onto it.
