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)
Thanks, I'll try that next day I work on it!
Hi Joshua. Curious about your plates but from the pic having trouble figuring out what material you used? Are these standard ACRO plate design?
Yes they actually are, I'll be updating this post later on today.
