Title: Crazy zero
Post by: wtxrcdog on July 06, 2019, 12:10:03 AM
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.

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.
