Folks -
I think 'bots have the same "crisis detector" found in so many other machines with electronics (read: copiers) When we're screwing around, or working on an element that isn't "mission critical" everything is fine - loose power in the middle of a cut? No problem, XYZ position is mantained.... Got something that HAS to be right... pffft...... 0,0 is somewhere around Barstow, on the edge of the desert... with apologies to Hunter S. Thompson
Okay, we were cutting picture frames with a 1/4 EM for doing all of the cut outs and rabbets, and a V bit for decorative carving. When we lost our registration, we went back and looked at the location of one of our registration dowel holes, and then plotted a reciprocal course back to what we assumed was 0,0. It looked okay, but we were off by 1/4 or so on our X. Y looked okay, but WTF? I had placed the EM directly above the dowel hole and VERY carefully lowered and positioned it so that I was probably within .010. When AC/PW gives you the location of a hole, is it taken at the edge or at the center?
We wasted several hours and 3 frame blanks, and Rose is spooked.... The last time this happened, we used the line of code to plot our way "home" but we picked the "highlighted" line, instead of the one before it. So, same problem, different solution, and we still have the same problem.
Aside from whatever gremlins are making 0,0 become a work of fiction, how the heck do you recover from position loss so that you can resume your location and registration point. We're only working in MDF, so it's not about $$ (this time) but boy....
On the theme of fiction, and writing, I can tell you that I learned some new words..... I am hoping someone can shine some light here...
Thanks in advance...
