I need help!!!.. On my Creality HI, I’ve replaced the front motherboard, the extruder, the extruder motor, and the filament sensor wire (all Creality original parts). I tried to extrude, and I still get the message that there is filament in the extruder (which is new), but the blue light does not come on as if there were filament in the channel. I tried to restore to factory, and got the CX2573 (X-axis abnormality) error message. I also updated the firmware on 4 May 2026. Please help or tell me where I can send it for repair.
look on the cables, may be the problem is not the sensor nor the board, instead a broken cable from nozzle to main board.
Thanks, I’ll check again, but I’ve changed almost all the wires. And it’s a pain because they all have to be ordered through Australia; it takes too long, and they are more expensive due to the shipping charges
Test the cable connecting the nozzle to the main board, the big harness.
I took it off and back on, don’t see anything wrong with it, but will replace it if I have to. Part number, anyone?
do not replace, take a multimeter and check continuity between each end of the cable.
