Flow sensor for the UM3
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

The feeder revision code r1/r2 has no relation to the S5 revision code r1/r2
