+Subject: No variable spindle and spindle speed fix.
+
+- When VARIABLE_SPINDLE output is disabled in config.h, the last commit
+would keep the spindle enable pin disabled when spindle speed is not
+defined (S0). This is now ignored and will enable with S0, as spindle
+speed is ignored in this mode.
