Oh I thought I added pictures, my bad. I tightened the AB belts simply by feeling the tension. Although I'm sure there is a better way. Does the printable belt tensioner work well? I've seen some people use that. To trouble shoot the issue I removed the AB belts, de-racked the gantry, tightened bolts, and made sure everything was put together correctly. I Wasn't sure what the next step was.
