The problem seems to be related to the system ignoring G40 (I believe)
I am told (and it makes sense) that G53, when used, only disables the Zero Offsets, (G54-57)
Status before move.
Z-axis is at +400 (m/c coordinate system, reading shown at Test N812)
The operator display is showing +350 (50mm Tool Length Offset active)
Then the following MDI Auto command was executed...
G0 G53 G90 G40 Z 410.000
(Move Z in rapid (G0), use m/c coordinates (G53), use absolute moves (G90), cancel tool offsets (G40) Move to +410, a +10mm move)
I believe the axis should have moved 10mm in the +ve direction BUT it moved 60mm +ve!
Final axis readings were...
N812 = +460
Op display = +410
So, am I right in assuming G40 (& G53) should have set the position register to m/c coordinate values, then moved +10mm (showing 410mm in N812)?
You think you're confused! It's taken me 20 minutes to type this!
Please comment on this, if it's only to say "good luck mate! (just nice to know someone actually reads my post!)
Have a nice day,
