Description

When booting Ender 3, screen holds on backlit but black. The only way to finish the boot is for filament to be loaded in the runnout sensor. E3V2-BLTouch-3x3-HS-v4.2.2-v2.0.1.bin and 5x5 both had same issue.

Steps to Reproduce

  1. Install E3V2-BLTouch-3x3-HS-v4.2.2-v2.0.1.bin on ender 3 V2
  2. Install runout sensor and connect to main board
  3. Do no load the runout sensor. Make sure the button is unpressed
  4. turn printer off then try to turn it on

Expected behavior: printer boots

Actual behavior: printer hangs on blank (backlit, but no image) screen
