Gantry belt Idler Adjustment

Does anyone know how to adjust the idler pulleys on the x beam of the gantry?
I’m hearing some rubbing on the left idler pulleys and can see that the belt is riding high.
I was able to get the pulleys in the front perpendicular enough to pretty much ride up and down without hitting the pulley belt guides, but the middle ones just ride high against the belt guide.

Any insight would be greatly appreciated!
