It was noted that the chute is open during purge, which means that the purged filament does not roll up. Because it does not roll up, it may get caught in the chute instead of falling all the way through. This could eventually lead to a clog, though the risk may be minimal as it may be noticed by an operator before it becomes a problem. So far this hasn't become an issue, so it will be added as an enhancement once there appears to be a stable P1P firmware.
