I notice that when I watch other videos zero in, when the grounded bit touches the positive plate, the bit stops and rises 1 inch and stops again.
On my diagnostics (Alt 7) section, one of the center top of port 1 pins remains lit until i lower the the grounded bit to the positive plate then the light goes out but router keeps going down until the limit switch is activated. Prior to testing the zeroing, the probe was automated set to 1-13 the only free space with out a problem. Any help will be appreciated. Eli
