Hello, I have a kit-built CNCRouterParts (now AvidCNC) 4'x4' CNC router. The machine is about 4 years old and has always been plagued with problems. Everything from mid-cut shifting, grinding motor sounds, losing zero, burned-out stepper driver, etc... it seems like there is always a new problem. I am currently running a DIY electronics setup consisting of NEMA 23's, an Ethernet Smoothstepper and Leadshine stepper driver. I am facing another costly repair in the electronics box and am fed up with a subpar CNC router. I believe that most of the problems can be traced back to the electronic/software setup and I am looking for a better option. The Blackbox is appealing because of its all-in-one setup, good reviews, software, and community support. As far as I can tell, my CNC router would be compatible with the Blackbox. The components of my old setup were much bulkier than the Blackbox, so I just want to make sure that I am not missing something obvious compatibility-wise. Thanks!
