+- Parsing support for O-Codes (subrotines). These O-Codes can be executed from .nc files in the root dir of a pre-configured file system (either C for MCU flash or D for SD cards)
 
 Version 1.10 added the following new major features.
 - added support SPI bulk transfers. This improves SPI transmission speeds while keeping the whole firmware responsive, opening the door for new modules and upgrades to µCNC using SPI driven hardware like TFT displays.
