Title: Newbie Z questions
Post by: Kingwood on March 06, 2014, 11:39:36 AM

Hello folks,

I hope someone could help with with these simple questions...
1. What is safe Z?
2. After setting my work Z zero high, running a gCode file, and closing my gCode, how do I get the Z height to return to Machine Z Zero rather than the program Zero?
3. What does the "GoTo" button do? The button under the DROs & next to "Go To Zero" ?

Thanks for your help,

Basil

1) A Z axis height setting in mach3.  Config > Safe Z.
With SafeZ is enabled, when you use Goto Zero, the Z axis will first move to the Safe Z height. You can also configure Mach3 to go to Safe Z when the stop button is clicked.

2) You need to add "G53 G0 X0 Y0 Z0" to your g-code. You probably want to move the Z axis up first.

3) Do you mean "ToGo"??

ToGo shows the distance a commanded move has left to go, for example if you are at X0 and command a move to X10, normally you would see the DRO count from 0-10, if you have ToGo selected you will see 10-0

ToGo changes the DRO's to display the distance remaining to the commanded position.
