A recent post, re. 'soft limits' (thanks kolias),  prompted me to write a macro to assist in setting my own soft limits.

 I would jog the X, Y and Z against their hard stops (that's acceptable/harmless with a Sherline mill).  Then the macro would back off all axes by 0.10, Ref All Home and zero the X, Y and Z work coords. Needless to say it didn't work.

So I have three questions:
1. What is the better/correct way to go about this?
2. What/where is the preferred Macro reference document? I go to the WIKI but didn't someone on the forum write  a  better document? I can't seem to find it.
3. And last, just for my own info, why doesn't my dumb macro work?

Here is the macro:
'Zero work coords
SetOEMDRO(800, 0.0)
SetOEMDRO(801, 0.0)
SetOEMDRO(802, 0.0)

'Then back off 0.10
Code "G00 X0.1 Y0.1 Z-0.1"

'Ref All Home
DoButton(22)
DoButton(23)
DoButton(24)
DoButton(25)

'Zero work coords
SetOEMDRO(800, 0.0)
SetOEMDRO(801, 0.0)
SetOEMDRO(802, 0.0)

Thanks,
Al

Try using the Zero buttons for the axis rather than setting the DRO. If you really want to set the DRO then possibly a sleep between each one would work. You will also likely need a

after the

Code "G00 X0.1 Y0.1 Z-0.1"

Thank you Hood, have it working now.
It did require two while - wends tho.

'Back off hard stops
Code "G91 G00 X0.015 Y0.015 Z-0.015"
Code "G90"
While IsMoving()
Wend

'Ref All Home
DoButton(22)
DoButton(23)
DoButton(24)
While IsMoving()
Wend

'Zero work coords
DoOEMButton(1008)
DoOEMButton(1009)
DoOEMButton(1010)
End

Thank you, Thank You Ray.
That's what I was looking for but for some reason couldn't find it.
