i am using mach3 version 2.0. i have a file that i have been running for aprox 6 months. latley sometimes the z will suddenly plunge aprox .375 too far. this has happened twice.
one other time when i homed the z it went up a little over 4in. [normal] hit the home switch & started back down, when it should have gone from 4 something to 3 something it went to 2.972 in the dro, but the z was actually at aprox 3.972 does anyone have any ideas what might be going on?
any help is very much appreciated. thanks greg
