Tonight my Shapeoko 5 Pro lost connection. I reconnected and reinitialized the machine and got an error. Upon further inspection this large retaining nut had worked it’s way loose.
I hand-tightened it and problem solved. But I do not have a wrench big enough to properly tighten this nut. Anybody know what size I need? Is there a torque spec? (Don’t have a torque wrench, but I don’t want to over-tighten it.)
A few months after getting my 5 Pro, I noticed the retaining nut had slightly loosened but hadn’t backed out entirely.
I used a 15/16" open-end wrench to hand-tighten it without applying a specific torque setting. It’s stayed secure ever since.
I also did a quick search and found this—it’s for the HDM, with a torque spec of 15Nm provided as the solution.
