printer-makergear-m2-2012.cfg

# Support for Makergear M2 printers circa 2012 that have the RAMBo
# v1.0d electronics along with the V3A extruder.  The electronics use
# Allegro A4984 stepper drivers with 1/8th micro-stepping.  To use
# this config, the firmware should be compiled for the AVR atmega2560.
