@Bricbasher If you have any problems we are here to help you. We have a team of people in our Customer Success department to walk you through every step of the way. If you need replacement parts we’ll help you there too. If you want to upgrade your machine when the new one comes out we’ll help you there too. I’d hold off on modding anything…
