In Need of Help

[slashr76]

I am new to cnc and machining. I have a Taig 2019CR ER with Mach3 Demo. When I start the cycle for a jpeg (Mortal Kombat Logo) i imported and converted, I have to stop the cycle to keep the end mill from cutting into my table. It just keeps going down. Homing and limits problem? I don't know. I'm not really understanding the tutorial on homing/limits at the machsupport website. I just need some basic pointers so I can get started and cut something. After I learn the routine, I'm sure I can figure it out. I would really appreciate any input as I am losing my mind. Thanks in advance.

Post the first 20 or so lines of your code.

You probably should post all the code. Attach it to the post.

I don't see a G90 to set machine to absolute. If the default is incremental, the z will go down every line.
