Re: [CAD_CAM_EDM_DRO] Re: Stepper motors only turning one direction

HI C,

If you are using the PC's power supply, then you don't need to connect
the PC's ground to the module. YOU DO need to connect +5V to the +5V
RETURN on the module (pin 10). Pin 1 is internally connected to 12.
What pin 13? Check the schematic, although pin numbers are for Gecko
G201/210. Also read the operating manual! Lotta good stuff.
