Ah, another thing. It works! When the first time I set the csv and the profile, the preheat kicks in. But, after the second time I connect my Therion 133 to escribe and try to change the preheat time to 0.75 second, the preheat didn't work. Already try to revert it back to 1 second and "trick" the DNA with "new coil" stuff and still no luck. Is there any way to make the preheat work again? Thanks!
