About the configuration. I don't know how to post that without making a mess but I just used the parameters that the spindle manufacturer sent me. With that config I was working ok for more than 6 months. So unless something was right there at the limit too far from the correct one. The main change here is ambient temperature. It's been almost 3 weeks with temperatures of about 38°C.
