The Binary G-code format is **incompatible with post-processing scripts**.

### Increase flow ratio

Increase **flow rate** by ×1.05‒1.1.

BrickLayers works for walls, so do not use 100% infill but more wall lines (it's stronger anyway even without this scirpt).

So to calibrate the flow rate more accurately, you can run the flow rate calibration and increase wall lines a lot. It's not perfect but it's a start.
