Search the forum for G52 command, this allows you to write your sub in absolute and call G52 X? Y? as local datum point. Use G52 X0 Y0 to cancel the shift before you issue the next.

General Mach Discussion / Re: Mach3 with a lathe - 6 axis simultaneous ?

If you are wanting to have the machine rapid one axis and be feeding on another then Mach3 V3****************** can NOT do this yet, to do that you need multi planners, that is for the future.

You can set certain ones with a #number , for example you can set fixture offsets that will update there positions by setting the #2500,2501,2502, for XY&Z on G54.

To zero out the absolute figures you just do a G92 X0 Y0 Z0 or any combination of axis.

G-Code, CAD, and CAM discussions / Re: Newbie question on G-code looping (While, for, etc.)

« on: March 21, 2010, 06:34:36 PM »

The only way to do loops at the moment is by using subs or VB macros

You can use # vars and operators but no IF's or WHILE, GOTO's or conditions LE, etc.

Search the forum for M98 and you will find lots of examples to do loops and conditions.

If Mach has no known home position it can not work to absolute values so it reverts to incremental values in G53
