Hi
Just finished tuning my motors and setting up my homing and limits, works well. I ran the road runner sample no spindle or tool and my Z stays up through the program and hits my limit switch half way thru, I assume because it has a raise Z g code. do I have something entered backwards for the Z command or do I need to zero the Z at a material height before starting.
Thanks Bill

............. do I need to zero the Z at a material height before starting.
Yes.
The surface of the material is typically Z0 in program coordinates.

Hi
Do I enter a Z0 in the g code before I run the roadrunner
Thanks Bill
-
No, you don't enter anything into the GCode.
Jog your Z axis down to the surface of the material, then enter 0 into the Z Axis DRO.
That will establish the proper relationship between the GCode and the actual material being machined.

Thanks will try
