Seems ams randomly will pull all filament back when in middle of single color print
I believe there would be less ams errors if it rewound less often
Do you know the reason for the pullback? Mine only pulls back the filament in case it ‘measures’ and overload on the the AMS motor (e.g. strangle of filement blocking the rolling the spool and provision of further filament). And it is only in very rare cases - at least on my machine.
It happens if the filament has too much resistance. Not sure if it uses the odometer or measures motor overload, but it’s an indication that you should make sure that your spool spins freely and isn’t tangled.
