I found during input shaping the belts would vibrate which ruins the results. The side and rear belt runs are long. By adding some idlers you can raise the resonance and avoid bad ADXL measurements.

1. For the side belts:
I added an idler to the X-Gantry Flange stack. The Idler is from left over V-Slot wheels from the ender 5.. just remove the rubber part. No modification is necessary to the printed part, just re arrange the stack and add a spacer and some washers. The original design puts the wheel in just the right spot to put a small amount of pressure on the belt.

2. For the rear belts
I printed a part that sits on the rear profile with an M5 Screw/T-Nut. Again, use two idlers from an old V-slot wheel, and a spacer in between. I used a dowel pin left over from the mercury one build, but you could use a M5 bolt.
Don't mount it at the center of the rear profile, off-set it. This will limit resonance.
