Thanks in advance to all here for even reading this, and hopefully pitching in. Bottom line: Main question: What would it take to make the OpenBuilds BlackBox work with the higher gantry and screw drives after upgrading a belt drive WorkBee 1510 to a QueenBee with lead screw drive? Nuance: Is the QueenBee Pro actually the most effective and economical way to: convert a belt drive to screw convert to linear bearings Raise the Z Long story: I just took delivery of my first CNC this week (WorkBee 1510). I shopped for a month, and in my ignorance was more focused on the 40x60 size, and a fast delivery time than on the drive mechanism. But now that I just finished assembly, it's absolutely clear that neither the Z height, nor the belt drive, are going to be adequate for what my business needs to do with this machine. As fate would have it, the cable for the Y limit switch go pulled tight to the track while finishing up the cable runs and zip tying, and I didn't catch it in time. So when I started the controller up and tested the travel, moving forward on the Y axis ran over the cable, pulled the wires out, and shorted the system. After re-terminating ALL the wires, and trying to re-connect the controller, troubleshooting eventually ended with not being able to flash, and it looks like the board was damaged beyond use. So If I have to replace the controller, and I know the machine is going to be converted to lead screw with a higher gantry, is simply replacing the BlackBox the right thing to do, or would that be throwing good money after bad if I will wind up needing a different controller anyway? Thanks again for any input here, and best wishes for your holidays.
