    Welcome Joshua, and congratulations on the build. I read about your issue. You probably need to adjust the pots (set Vref) on your DRV8825 drivers to get adequate current to cause the steppers to turn. Do a search on "current adjustment drv8825". Here's one link: UPDATE: Current adjustment for motor drivers (DRV8825 / A4988)

    Hi Joshua. Curious about your plates but from the pic having trouble figuring out what material you used? Are these standard ACRO plate design?
