This is to solve a potential problem while feeding to printer's drive gears - while disengaging the Idler, the Pulley was still rotating to avoid grinding the filament (printer is pulling it). Other filaments could have moved a bit when the Idler's bearings ran over them while the Pulley was still rotating slowly -> the filament could have been moved into the Selector's path causing trouble (especially when not used in the print). Therefore, the Idler disengages partially now - moves into an intermediate position between the slots. Then, the Pulley is completely stopped and after that the Idler does a full disengage like before. |
