				I have been trying for some time to get my Grizzly G0 704 mill to work correctly. Here is what happens. I did a design in Fusion 360 and did the code. When i try to start the program the tool is set to zero on the surface of the stock. When I press start the Z axis goes up usually till it hits the end of travel and keeps going loosing its place. is it with my code or is it my machine setup? I have a router that works great and this has me stumped.

				pls post your GCode.

				  Attached is the code   
 
 Thanks
- 
				from your code:
 
 ...
 Z0.6
 G28 G91 Z0.
 G90
 ...
 
 from Mach3 GCode help:
 G28 should not be used in one line with G90/G91
 
 
 Switch your machine ti single BLK mode and step through code to see where exactly the move up is initiated.
