anyone know why my x,y,andz axis are running backwards

Are you using Mach3?

The software has no idea where your motors are installed, so it has no concept of front / back.

If you want to switch directions, go to Config > Ports and Pins > Motor Outputs... and place a checkmark next to "Dir Low Active".

This will reverse the axis' direction.

I am running Mach 3.I bought the machine from someone and just got it set up and running.Never did any cnc work, this should be a challenge .I check marked Dir. lowactive and that did the trick.I am sure there will be a lot more help that is needed

Now how do I set a home position for every setup to start from?

You can set your machine coordinates to zero. That will act like a home position.

Just don't move your machine manually while the power / computer is off and it should keep this position.. but you may have to set it each time you start the machine just to be sure.

are there any video tutorials for the aquickcnc on any site for someone who doesn't have a lot of cnc knowledge.

You might be able to find some helpful videos on YouTube:
