Stop button on ,,,, not really

[ccwerks]

I am running a tool path set in mm. (machine is still in Inches)
For some reason it wants to kick up the error "TOOL STOP BUTTON IS ON" and then goes in to a fault on inp 4. I have checked line 9 and find nothing remarkable about it. "LN:9 1052.99, 375.00, 92.00"
Needless to say the stop button is not on.
When I set the top of material routine up it says it will convert the results to mm. Is it possible that the conversion is mucking it up? I am stuck, I have rewritten the tool path several times and still wind up with the same result.

Are you sure your machine is not being sent past the prox switches and up against a mechanical stop? Check all axis at the point of fault. Someone else had a similar condition lately and they were bottoming out on the lower Z axis hard stop.

What Scott said. And I have topped out with my machine when I was working with thick material, due to the min Z height setting over the top of the substrate. This too, will throw an Input 4 Error...
