TOS-KURIM CNC Upgrade

[JimJam]

Starting to get somewhere with wiring it all up now, just a quick query before I do something stupid...

so the wiring instructions for the main plug from the drive to AXBB board are:

The pinout of the Main connector is listed below:

1) Step signal input
2) Direction signal input
3) Ground for Step and Direction signals (NOT for power)
4) 5V power input. (if this input is fed then the 7.pin should not be connected!)
5) Reset (input) and Stop input)
6) Error (output) and Stop input
7) DC power + (12V DC input for digital processor)
8) DC power – (ground for the 12V DC power supply)

Step 3 says NOT for power, but the wiring diagram shows it connected to the 0V of the 5VDC power supply...
