Tool Change Type Bug
On some versions of Mach4 there is a bug that does not allow you to change the Tool Change Type. It will be stuck on T on M6 line is next tool. This has been fixed in current Mach4 releases but you may run across this once in a while.
There are two fixes to this:
- Update Mach4 to the current release. Depending on custom programming, this may not be a viable solution.
- Make sure Mach4 is closed. Go into the profile folder and delete parameters.ini and sysvars.dat files. Restart Mach4 and you should be able to alter the Tool Change Type.
