What would be solutions to fix the axis drive fault? It will not let me home the machine.

If you get an axis drive fault when you attempt to home, something is wrong with the first commanded move. The move is commanded but not made. In a 3 axis machine, the Z would be the problem. A simple trouble shooting would be to switch two of the axis drive units. Z and Y or X and Y for the 2 axis. If the fault is in the drive, then first axis would home before the failure.

What if all three of the drive units in the cabinet has red LED.

Have someone there to help you (be ready to hit the E Stop) with this to find out which axis is bad. With the servos on, remove the ice cube relay (it's a clear relay about the size of an ice cube) and you should see the bad axis stay red and good ones be green. The table might run away when you do this, hence having someone there with you.

The drives all have red lights until they home. You are having a failure with the first drive or axis in the homing process.

Does the machine move otherwise, if you can jog all axis then how can there be issues with drives. I would not try to switch cables around unless its the last resort as I have smoked good drives doing this... all red light could be external command for controller that status bits are not met??? maybe a bit is not true... can you look into the status of bits on your machine I.E maintainace level
