Title: Macro for Z-axis probe
Post by: PerE on September 13, 2006, 09:50:55 AM

I want a simple macro that lower the z-axis down until i hits the probe and then the thickness (that i know) of the probe get into the z-axis DRO.
Do i have to put the thickness of the probe in the macro or can the macro ask me if i want to set another thickness of the probe and save it even if i switch the computer off ?
Best regards from

I think if you look there is a tool probe macro on the forum that will do just that! It is a few messages down and if you can't find it post here and I will help you :)

Thanks
Brian

Code”G31 Z-100 F25” ’Down with Z
While IsMoving()
Wend
GetVar(2002)’Hit the probe
Call SetDRO(2,2.000)’Sets the probehigh

To clear this what i am doing:
I have an isolated plate that is 2.000 mm thick that i put on the surface of my workingpiece and it is connected to pin 13 at port 2.
Its a very simple macro but it helps me to set the tool more accurate then a piece of paper  ;)

I will like to ask when You write a macro How and where do You actually put the code? at the beginning of the gcode? or is this a separated issue? I have just started with Mach  so patience will be appreciated.
Thank You,Marco.

Hi Marco.
This macro is in the Mach3 screen "program run" - "tool information" and i put it in the button "auto tool zero".
You have to write the macro in notepad or word then copy it.
After that you have to open Mach3Screen and double clic on the "auto tool zero" button then paste the macro you have in there.
Hope this will help you a little bit.
Good luck.

Put in a G91 to make the move incremental

Also be sure to put a G90 at the end of the macro
