Xerxes, thanks for the quick reply, I think my problem is a hardware issue, I got what seemed like a half pound of plastic shavings out of the ball nut when I disassembled it, once reassembled I tested the motor again and it read 1 encoder pulse over 4 poles, that's just off by 4999, I expect a wiring problem is the issue and could explain the intermittent nature of the problem. |
