DT technician here in a UK secondary school. We have two Ender 5 S1 printers and one has developed an issue with the extruder motor. When printing the motor sometimes does not work at all, the printer prints as if it is working moving about the bed but extruding no filament. Other times it will run for a period and will be extruding filament then either stops completley again or trys to work but looks like the cog/wheel is slipping. I initially thought the motor was failing so bought a new one and replaced it but it still has the same issues. The print head/nozzle is not blocked, ive checked for loose cables and am a bit stumped. When loading filament the motor works well and ive added resistance to the cog/wheel with my finger and it is strong in feeding the filament through but at the point of printing something is where it begins to fail in the way ive described above. Any input or ideas of what my issue could be would be gratefully received. Thanks
So you confirm the motor stops turning at some point ?
Just to make sure if I understand correctly
In that case, can you check if that’s really the motor who stopped turning or the filament which stopped feeding ? (the motor keeps turning but it doesn’t pull the filament anymore). That could be heat creep
I believe the motor stops as the cog that is visible at the top where the filament feds in stops turning. I’ve heard of heat creep causing the motor to stop but I can’t say I’ve noticed the motor getting particularly hot. Is there a way to test if it’s heat creep or to stop it? Thanks
It is generally heatcrimp when the filament looks mashed. It happens when the fan of the heatsink is malfunctioning (always on, can’t be controlled by the user)..Either way, It shouldn’t stop the motor as it only impacts the filament (thus my first question !)
Since your motor is stopping, I think it can only be a wire issue, a adapter board or a motherboard issue ?
