[QtDragon][2.9.4] Tool probe starts before M6 dialog "OK" confirmation

Hi all,

After upgrading from LinuxCNC 2.9.3 to 2.9.4, I encountered an issue in QtDragon where the tool probing routine (qt_auto_probe_tool) starts before I press the “OK” button in the manual tool change dialog (M6).

This behavior was not present in 2.9.3. Previously, the probing would only begin after confirming the tool change.

I found that explicitly disabling the automatic probing behavior in the INI file resolves the issue:

ini
[DISPLAY]
AUTO_TOOL_PROBE = False

This stops QtVCP from launching the tool probe automatically right after M6, allowing me to call the probing subroutine manually after user confirmation.

LinuxCNC 2.9.4 (Debian Bookworm)

QtDragon UI

Manual tool change with M6 remap (calling qt_auto_probe_tool.ngc manually after M6)

I hope this helps others running into the same problem.
If this change in behavior is intended in 2.9.4, it might be worth documenting.

Thanks!

AUTO_TOOL_PROBE = False

Where did that come from? I don't see anything that reads it.

I'm sorry.
It seems it was my misunderstanding.
