Last night I was configuring modbus in Mach4 for my plasma setup and pretty much have it right.
what is very strange is that now instead of Mach4 displaying Mach4 hobby in the upper left corner is displays "Pierce Height Hobby"

Pierce Height was one of the variables I set up in modbus but why/how did it change the name of the program?

I feel like I should find out how to fix this before I waste any more time configuring the rest of the program.

I've attached a pic and my profile file.
note, I imported this profile file to another computer and it too show's Pierce Height Hobby in the upper left corner.

I'm stumped!!

Any ideas???

Because that is what you set for the screen label.  In this screen, the label is set to Mach 4.
