6.4.7 Global Configuration Dialogue
This dialogue shows global status flags on the front tab and global settings on the rear tab. These
flags and settings are related to the GENERAL CONFIGURATION REGISTERS of the TMC5031. Flags can be
pulled continuously or on demand. Blue marked flags are set.
Note that the direction of motor 2 is reversed per default. This way, both motors rotate in the same
direction. In hardware, motor 2 is connected mirror-inverted.
