Is there a code (G or M or ?) that will zero out an axis without traveling to zero?
I am using the 4th axis as an extruder (3D printer) and when the print is done I want to zero out the display, but I don't want the motor to move.
I know I can do this manually which is great until I forget to zero and I unwind my filament when I start the next print.
Thanks,
Pete

Hi Pete,
Welcome to the forum.
There is always more than one way but this is perhaps the easiest…
Create a macro (in your Mach3, macros, [your profile (typically Mach3Mill)] folder called M999.m1s (this is typically a Word Pad document with an .m1s file extension)
Enter into the macro the commands of your choice.
For example: A M999.m1s macro containing the command DoOEMButton(1008) will zero the X axis DRO whenever the Code M999 is called within your program.
More info on macros and the OEM Button codes can be found in this document http://www.machsupport.com/wp-content/uploads/2013/02/Mach3_V3.x_Macro_Prog_Ref.pdf
Tweakie.

You could just do a G92 A0
