Stop coolant during park

[gcormier]

Is it possible to have grblHal stop coolant during park? My button 3 triggers park.

I have seen a few options but my mist is staying acting while parked, and I cannot toggle it from ioSender while in the park state.

Note I do not hit feed hold first, I simply hit the park button.

Mist should be disabled, which driver/board?

[gcormier]

STM32F4xx, SLBEXT.

Confirmed today. I hit my button 3 which is configured as "Park". I push it, the machien stops, I see "DOOR:0" in ioSender, spindle stops, but the mist remains on.

I have just tested with a STM32F4 board and that works, so perhaps you have an old and buggy version?
The build date is used to identify the version, it can be found in the $I output:

[VER:1.1f.20251109:]

I can check on monday. I believe it's 20251111.

What is your $61 setting?

[gcormier]

I don't have one

...
$45=3
$46=0
$47=0
$56=5.0
$57=100.0
$58=-5.0
$59=500.0
$60=1
$62=0
$63=3
$64=0
$65=8
$70=11
...

I had to disable safety-door , in order to be able to add a 2nd probe.

Pressing button number 3 on my remote

Ok, I believe the $61 flag for Keep coolant state on door open is set causing the issue.
Can you make a settings backup, reset the core settings with $RST=$, and then restore them? This should clear the flag (unless it is set as default with a compile-time option).

[gcormier]

Bingo - -D DEFAULT_DOOR_KEEP_COOLANT_ON=1 was set in platformio.ini.

I had to recompile, flash, but also reset settings as you suggested. It showed the same behaviour until running $rst=$ and reloading my config.
