Joint use of a relay and a PWM laser about grbl_esp32_mpcnc_controller HOT 5 OPEN

You could use the spindle enable pin for the relay.

#define SPINDLE_ENABLE_PIN GPIO_NUM_2

from grbl_esp32_mpcnc_controller.

I tried this option. When it is in the mode $32=0, the spindle works as it should, but

when entering the parameter $32=1 and flashing the code
//#define USE_SPINDLE_RELAY

#ifdef USE_SPINDLE_RELAY
#ifdef V1P1
#define SPINDLE_PWM_PIN GPIO_NUM_17
#else // V1p2
#define SPINDLE_PWM_PIN GPIO_NUM_2
#endif
#else
#define SPINDLE_PWM_PIN GPIO_NUM_16
#define SPINDLE_ENABLE_PIN GPIO_NUM_2
#endif

the relay is often switched on/off, but there is no PWM signal at output 16. If

//#define USE_SPINDLE_RELAY

#ifdef USE_SPINDLE_RELAY
#ifdef V1P1
#define SPINDLE_PWM_PIN GPIO_NUM_17
#else // V1p2
#define SPINDLE_PWM_PIN GPIO_NUM_2
#endif
#else
#define SPINDLE_PWM_PIN GPIO_NUM_16
#define SPINDLE_ENABLE_PIN GPIO_NUM_32
#endif

the PWM signal on the pwm output (pin 16) works as it should.

I might be able to write a custom machine definition file.

It would help to know exactly what you are trying to do and why.

On the lowrider machine, allot of people have both a spindle and laser mounted at the same time. It would be nice to have the relay for turning on the spindle and PWM to run the laser. You would just then not supply source power to whichever tool you are not using.

I made this well i tried 3 methods with videos. Linked pt1 https://youtube.com/shorts/0fDZFcwfVqU?si=npPupSD3e--cxUIT

Pt2 and coming. I burned my little red stepper driver and I have tried to use one blue relay and then I tried 1 blue relay controlling a regulator big relay and then that didn't work so I tried high and low trigger relay which really didn't work . Going thru drivers alot hahah
