Activation M7, M8, M9

[nichtdiemama84]

Hi Everything is working quit well because of your help. Thanks a lot !

My hopefully last problem is to turn on the vac and the coolant. I don't need the spindle pwm output. I would like to use the This output for the vac (M7) and a another one for the coolant (M8). But i can't figure it out how to configure it. When i try to use the commands M7, M8, M9 i get an error message.

Which board map do you use?

The protoneer one. Pin18 Spindle on/off, Pin19 vac, Pin0 coolant.

M8/M9 does not error out for me.
M7 is not mapped to a pin, if you disable PWM with -D SPINDLE0_ENABLE=7 in platformio.ini you can control IO18 with M64P0/M65P0 or if you modify the map file by changing this line to #define COOLANT_MIST_PIN AUXOUTPUT0_PIN you can use M7.

FYI you can check pin mappings with the $pins command, this is what I get with -D SPINDLE0_ENABLE=7:

[PIN:4,Feed hold]
[PIN:35,Cycle start]
[PIN:2,Emergency stop]
[PIN:39,Probe]
[PIN:13,X limit min]
[PIN:5,Y limit min]
[PIN:23,Z limit min]
[PIN:36,Aux in 1,P0]
[PIN:26,X step]
[PIN:25,Y step]
[PIN:17,Z step]
[PIN:16,X dir]
[PIN:27,Y dir]
[PIN:14,Z dir]
[PIN:12,Steppers enable]
[PIN:19,Spindle on]
[PIN:0,Flood]
[PIN:18,Aux out 0,P0]
[PIN:34,RX,Primary UART]
[PIN:35,TX,Primary UART]

Thanks i will try it.
