Sapphire Plus 1.1 Mks Robin Nano 1.2 (0004) + 3D Touch

Important! Do not configure pin_up_reports_not_triggered or pin_up_touch_mode_reports_triggered to False without first following these directions. Do not configure either of these to False on a genuine BL-Touch. Incorrectly setting these to False can increase probing time and can increase the risk of damaging the printer.
It's a good idea to verify that the Z offset is close to 1mm. If not, then you probably want to move the probe up or down to fix this.
