MACH3 error help

Hi Aus/NZ Club Housers,

I have a Sieg X2 mill to CNC conversion, driven by a Gecko G540 4-Axis Driver Controller in a CNC controller box:

High-Torque Stepper Motor, Stepper Motor, Driver, Stepper Motor kit, DC Servo Motor, DC Servo Motor kit, Stepper Motor Power Supply, CNC Router, Spindle, and other Components. Automation Technology Inc

I have checked the wiring of the box and the motors with the manufacturer, who assure me it is correct, so I'm assuming it must be an issue with MACH3 and my PC (which is purely for MACH3 use only).

All X, Y, and Z motors (Nema 23's) receive power, and act the same way across all motor driver plugs on the Gecko. This is what happens when I use them:

X-AXIS- (X-left key)= motor turns left. (X-right key)= motor turns left.
Y-AXIS- (Y-left key)= nothing happens. (Y-right key)= nothing happens. When I use (Z-left key) instead= motor turns left. When I use (Z-right key) instead= motor turns left.
Z-AXIS- (Z-left key)= nothing happens. (Z-right key)= nothing happens. Same outcome when I try the other keys.

This happens whether I use the axis control keys on my keyboard, or TAB and use the on-screen buttons in MACH3.

The only change I made in MACH3 when setting up my profile was to put a tick next to my E-STOP 'enabled' and 'active low' in Config/Ports and Pins. That was the only way I could get the Reset button to stop flashing.

Does anyone have any suggestions, or further information I should provide?

Thank you all.
