# Configuration for printer composed of:

# SKR Mini E3 v3 Mainboard

# Custom macros are used to contain standardized code, slicer gcode calls these macros. 
# The g-code below is used in Orca Slicer, but can be used in Prusa Slicer with minimal modifications.
# Start g-code is intended to use adaptive bed meshes, together with Orca Slicer's support.
# Omit PRINT_MIN, PRINT_MAX, MESH_ALGORITHM, and PROBE_COUNT to disable adaptive bed mesh.
# The load and unload macros don't work great (if at all), as the direct drive head really needs to be loaded and unloaded manually.
