Print Start Macro

This is ONLY required if using Touch Mode with your cartographer. DO NOT use this if you're using SCAN mode

Adding the CARTOGRAPHER_TOUCH command to your print start macro ensures that the printer performs a precise touch probe AFTER executing the BED_MESH_CALIBRATE command. CARTOGRAPHER_TOUCH should also be performed with a nozzle no hotter than 150c. With this in mind, the command will fail if the nozzle is beyond this temperature. It CAN be performed cold. Please make allowances for this in your print start. This sequence helps to achieve an accurate bed leveling by accounting for any variations or offsets after the mesh calibration.

It is not recommended to use a custom BED_MESH_CALIBRATE or ADAPTIVE MESH macro/plugin

PLEASE DONT USE THIS - IT IS AN EXAMPLE ONLY

The following is a modified version of Jontek2's Better Print Start Macro which incorporates Cartographer_Touch commands for use with Voron printers and can be adapted for others.

## *** THINGS TO UNCOMMENT: ***
## Bed mesh (2 lines at 2 locations)
## Nevermore (if you have one)
## Z_TILT_ADJUST (For Trident only)
## QUAD_GANTRY_LEVEL (For V2.4 only)
