Title: homed axis (XYZ) DRO does not read zero
Post by: geone on October 11, 2011, 02:13:00 PM

Can't seem to get it right:

I referenced all and the machine completed as expected, however, the DRO are not showing zero.  I cannot figure out how to get them to read the home value.  I am trying reference the machine so the cutting area can be moved away from the home(s).  I am expecting the DRO to read zero on all axis.  Yes?
thanks

Only when you are viewing the machine coords will you see the axis zero when you home, normally you are viewing the offset coords.
If you are viewing Machine Coords and when you home they dont zero then likely you have a Home Off value set on Homing and Limits page.

DO you have the auto zero checked for homing or are you using a home offset value OR are you using the set values for G28?

If you look in the Mach3screen reference manual on page 23 it shows the options you can choose to use to setup the home positions. There are many(;-)

Just a thought,(;-) TP

I pulled the trigger too quick...I reread the manual and as you indicate, user error...set the auto zero and all is well

TP, where do I find the Mach3screen manual? I have downloaded, printed and bound most of the Mach manuals, but I guess this one slipped by me.
