Can someone have a look at the video clip I have linked below?
It shows my Mach3 plasma screen before a file load, during file load and then when pressing my "Set Origin" button.
As you will see, the Z is happily parked at 14.991mm which is where it really was after the end of the previous run. When i press set-origin it jumps to 0.437mm then to -0.9mm then to 0.437mm where it stays. The actual axis does not move - just the DRO freaks out and leaves a meaningless reading on it which puts it in a bad position for a dry run on a new file.
The 14.991mm is wrong as well because my final Z move is always to 15mm dead, the difference between 15mm and 14.991mm is the reading of the "THC Adjustments" DRO when the last cut finishes, if i run with THC off it always ends on 15mm dead.
Here is a link to a video showing what I believe to be odd behaviour of my Z-axis DRO.
