And a 24v, 5a power supply. I am using Grblcontrol(Candle_1.1.7 ) as my software.

When I input jog commands, the motors vibrate and jerk and don't spin smoothly. They are under no load and the Vref is set to 0.65. Sometimes they just vibrate and sound like they're spinning but aren't. Can anyone help me or recommend some new electronics that are easy to set up.

Welcome to the forum! First question has to be - are you certain you've wired everything correctly?

Pretty sure you wired the steppers incorrectly and the 2 poles are fighting against each other. You can try swapping wire from pin 1 to pin 4 and from pin 4 to pin 1.

I may have done the same thing at some point that's how I know what to try.
