Hi folks. I built my machine some time ago. It was the C-Beam Plate maker I enlarged to 1000x1000 or 39x39. I have gotten a lot of use out of this machine and veterans have worked with me learning new skills and making items for their own use. When I purchased My machine, the controller was the old X1 which did not have probing and was very limited. I understand now, the new controller is amazingly efficient and has a lot more features. I also see some new software and other upgrades have been available. So aside form the controller board, what other components are new form a couple years ago? Horror stories, positive reports on upgrades or anything? Id love to hear about them.
