Some Good News! I finished reattaching the last couple of wires, and powered up the unit just to see what would happen. No More Error Message!!! Well, that's somethin', anyway. Next I have to reattach the drive belts to the X and Y Axis motors, something that was described in great detail in the Youtube video I mentioned earlier. I'm also going to add the 3D Touch, and then give it another go. Not sure exactly how it's supposed to work because there are no instructions, but I'm guessing that there's a Youtube video around where someone has dealt with it. Beyond that, I have to figure out how to load filament the correct way and then figure out how to tell it to print something. The basic filament path is pretty clear, but there's a couple of components along the way that the filament goes through, so, something else to learn about. But, hey, progress, right? :-)Thanks again.Ron
