I figured out why the "Lathe" Z tool offsets were out by 7.5mm when doing a manual tool offset measurement.
In the probe setup page where you put the measurements of the probe i had the width of the probe stylus set to 7.5mm.
Why this affects a manual tool offset is a problem for Centoid to fix PLEASE can it be fixed in the next software version upgrade.
Also in the tool table It would be nice to have a column for the width of the grooving tool so as when you program a groove in intercom it takes the tool width into consideration when setting the groove width.
Also the tool table needs a diameter column for the drills so that the probe knows the diameter of the drill being probed in the auto probe cycle.

Re: Tool offsets Lathe
The width of the probe is only for auto measure ZX, so after measuring Z the CNC knows the center of the probes width.
Measuring drills in X with the probe is a "bad habit", because if the drill edge is not exactly set in height you get wrong values, set X0 of the toolholder with a dial indicator and auto measure only Z.

Yes but if there is a figure in the setup page for the width of the stylus.suntravel wrote: ↑Mon Feb 19, 2024 8:48 am The width of the probe is only for auto measure ZX, so after measuring Z the CNC knows the center of the probes width.

When i do a manual tool offset in Z it affects the Z offset by -7.5mm

Re: Tool offsets Lathe
If you have set Z Ref with the probe, manual Z measure at another Z position than that of the probe will not work.
If I have to set Z for a tool and do not want to use the probe while a part ist in the spindle, I make sure the tool is selected and drive it to part Z 0.
Than I correct its Z offset so the DRO shows Z 0 for this tool.
