This is how I think 3 axis homing works. Is it correct?
Let's say that the X Y Home switches are located in the left rear position and 1/4" away from the Limit switches. And the Z axis homing switch is located 1/4 below the upper Z axis Limit switch.
When the Home button is pushed the Z axis is moved first up to it's Home position, then the other two steppers are activated and the router is moved to the left rear direction until their Home switches are activated.
Is this sequence correct? Z moves first?
In the situation where you have hit the left rear limit switch, you couldn't press the Home button because the machine would want to drive it to the left rear, its normal home drive direction. This raises two questions.
1. Does Mach 3 know it location, and would drive Home safely, even when activating the left rear Limit switchs?
2. Or would you have to Jog it past the Home switches then hit the Home button?
Thanks for the patience in reading this long draw out question.
