six nibbles ... BIN6 ?
I tried to get a BIN6 scale to work on the Mixed Scale board and found that it didn't understand negative numbers. You have a scope. Watch for the MSB to change and see if that's when your values go wrong. I posted about it here at the time.
I've equipped both my lathe and mill with Shars aluminum scales. There is no practical difference between them and the stainless scales, and they're a lot easier to work with (and Shars has them on sale). I have no affiliation with Shars other than as a satisfied customer. They are working great, but I had to add supply decoupling capacitors in the read heads on the lathe for stability. I had a LED lamp that really made them go crazy before I installed the caps. The mill that I'm working on now doesn't seem to have the same problem, but I may do the mod anyway just to be sure.
The perils of DIY.
