Railcore Y-Rail Alignment Tool (Y-RAT). Will work with or without halo. Use these tools together with clamps while tensioning your belts to make sure your Y-rail stays parallel to your right 1515 extrusion.
There are tabs at the bottom of the tools that go against the bottom of the right 1515 extrusion for easy alignment while tightening the clamp.
Print 2 of the same STL. This works great when you are first building, working on the belt path, or (how I usually use them) with the air print method of belt tensioning. That method can be done with the macro below, and double checking the Y-rail is parallel to the right extrusion when you've got the belts just to the point of not vibrating. You will have to disable the motors to move the Y-rail back to make contact with the Y-RATs to confirm of course. You can get fancy and modify the macro to home X and Y at the beginning and disable motors at the end if you want so you don't have to do it manually.
IMPORTANT: be sure your fan doesn't crash into the Y-RATs at X=270 BEFORE you run this macro!
; Airprint a box for belt adjustment.
; First belts should be loose, almost dropping off.
; Home first then drop the bed 25 mm or more. You should do this manually.
; Run the below code and the belts will vibrate like a guitar string.
; Tighten a little bit and repeat until the belts get to a point where they don’t vibrate.
; At that point, you’re done.
