Hello
I use smoothstepper and mach3 I have a problem with spindle pwm at start of gcode

With cycle start button gcode starts as a code m3 s15000
Spindle relay closes but pwm out gives 0volt so spindle doesn't turn
I stop the code and push the "spindle cw f5 button " spindle starts turning
Resuming the code by pushing cycle start
Please help me why my spindle doesn't start turning normally
