Hello all I am new here and I just bought a DIY CNC ROUTER 16.48.4 that has 4-wire motors and I am in the process of setting it up with MACH3 but I think something has gone wrong.

My CNC goes all the way to the right and not to the left on my Y Axis.

My X Axis comes all the way forward but will not go away from me.

My Z Axis goes all the way up but will not go all the way down.

I bought my stepper motors from here 3 Nema23 Stepper Motor 270oz-in+3 axis board CNC kit - eBay (item 300488540670 end time Apr-01-11 07:31:59 PDT) and it claims that my color wires are these:

RED A+
GREEN A-
YELLOW B+
BLUE B-


My motors are 3.5A and only 4 wires.




These are the items I received with the stepper motors

•1 x 3 axis TB6560 Stepper Motor Driver board V type
•1 x DB25 parallel cable
•1 x Fan,4pcs M4 screw
•3 x 23HS8430 stepper motor
•1 x 200W 24VDC switching power supply


I bought the exact same color wiring to make sure I did not make a mistake when I hooked them up to the board.

Could someone please help me out and let me know what I am doing wrong.

Thank you ahead of time in advance.
