[guide] DSLR snapshots - mainboard GPIO triggered

[ihrapsa]

This macro triggers pin PC6 on the Creality v4.2.2 board display port and can be used to trigger a 3.3V relay module in order to act as a shutter for your DSLR. Call this cheese macro inside your slicer layer change post processing settings.

Note! To make parked snapshots you have to put this cheese macro inside another macro that parks the head and call this latter macro inside the slicer instead.

Many thanks to Fry Sennberg for this
