First off realize I'm absolutely a beginner at cnc work, you may have to interpret some of my post.
My work has a LJ63M sitting forlorn, gathering dust. I replaced the drawtube over a year ago(the first time anyone has done anything with it since it arrived ~9 years ago), changed the fluids and cleaned it up. One of the guys messed with it and couldn't get it to communicate with the shop computer. Yesterday I was asking about it and gathered from him that a error code BJ807 showed, and all progress stopped. This was from his memory and he admits possible errors with that as well.
Does that error ring true? What are the probable causes of it? And last, is there some list of errors that we could get from someone here? We have 3 books on the machine I believe, none of them contain error codes. Thank you, Loren.
