Hey everyone.   @Enigma_M4 @fbrc8-erin @3dprintz   I've successfully upgraded to S5 feeders on my UM3 with instructions from CarloK.    I've put together a detailed write-up for making the upgrades.  The doc is still a WIP and I'll be adding more photos, but thought this would be nice if anyone is adventurous. I've been testing it for two weeks a now and so far so good!   It gives abrasion resistant feeders and flow sensor.  Also the S5 feeder is just way nicer to change filament us
