Is the new version you installed the same version you're using on the other PC?
If not the plugins will be a mis-match for the two versions of MACH4 meaning you'll have issues.
I am using the original computer set up for this machine. I am trying to update the installation to the current version that supports probing through the GUI. The machine came to me with one folder on the c drive named Mach4Hobby containing an installation and another folder labeled Mach4Proto containing an installation. I have tried installing into both the folders. I have changed the name on the Mach4Proto folder (containing the profile that functions) and then installing into it. I've tried all kinds of things but there must be something I am missing...
I also tried changing the IP address to 10.1.1.2 to no avail. I can see the Mac address of the CSMIO/IP after getting my new installation configured. But I can not seem to see any communication back from the controller. no Estop messaged, Probe input light in the GUI (it works on the controller and legacy profile) Etc...
Thanks for the suggestions!
