In the middle of assembling my SO4 and I have a couple of questions. I cannot find an install guide for it. I imagine that we needed to follow the assembly video for it, which I did. My question is how do I mount the BitSetter? I bought one and I do see threaded holes on the power button plate. After reading and researching that looks like the area where it’s supposed to go. Is that something extra I need to buy? Can I use the bitsetter without mounting it? The second thing is the YL cable. I connected it and routed it under the plate on the gantry. Is that how that is supposed to go? I have added pics. Everything seems to be working fine. Still haven’t cut anything yet, just did the hello world and the middle came out lighter which I probably set zero too deep so it came out lighter towards the end. Any recommendations on a first project? Complete newbie here. Thanks in advance.
