The hal pins are changed in control.c lines 1761 for spindle on line 1762 for forward line 1763 for reverse HAL pin 'spindle on' is based on emc status of spindle speed * emc status net_spindle_scale In other words spindle is on if emc status spindle speed is not 0 - off if it is 0 Presumably M5 sets emc status spindle speed to 0 somewhere and presumably m3/m4 tells emc to transfer the gcode s speed to emc status spindle speed The m codes are not directly controlling the HAL pins So its alot more work to fix this then you hoped. Thats how I see it from a quick look - not that I'm any expert with the guts of EMC
