I have the USB controller board and the 8825 step driver. I need a wiring diagram between the two. Specifically, what does the GND pin on the X-axis connect to? Also, what does the 5V pin on the driv

You can find a wiring diagram here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/ The CP terminal is wired to the step terminal on the 8825 step driver. The CW terminal is wired to the direction terminal on the 8825 step driver. The GND terminal connects to the GND on the 8825 step driver The 5V connector on the driver simply powers the logic side of the chip and needs to connect to VCC pin on the keyboard jog. Customer Response: Thanks! Working now.
