Hi,
I just got an offer for Chinese DROs (to fit onto a mill or a lathe), that are quite cheap. I _would_ prefer Heidenhain, Sony or Mitutoyo, but not my wallet! These cheapos seem to have a resolution of 1/100mm, but what's their accuracy?
I do have a Tek TDS waiting for some waves to sample, a programmer for uCs, a laptop willing to cycle through some C-code and the knowledge to put all the things together ...
