Pet Feeder

this is the enlarged version for larger dog food. i see no problem spinning it out here but if you need to insert a plate over the front half of augger to make sure it comes out without bunging up due to (dogfood)hydrostatic pressure.

has end attachment for optical sensor / jam detector / reverse - optical sensor needs to be enlarged , and screw needs to be filed down on the corners.

the stepper coupler is really tight, it needs to be drilled out on the sides a bit more just set against the sides and spin the drill. prefit the 2 peices together before inserting into hopper and bolt in motor.
