1. I did a fresh install of the current UCCNC on an old laptop running Windows 10. UCCNC does not recognize the registration file copied into the \UCCNC folder? Im only able to run it in Demo mode. (I´m using the same LAN cable, and have rebooted several times)
Try deleting and re-copying the file.
So.... First install a clean install of current uccnc in a new folder (not overwriting anything in the existing folder.... Enable the plugin, and set up the ports and pins for motion (xyzabc axis ,estop and probe input... Run uccnc on the machine .... Does the probing work fine via the new probing screenshot in uccnc....
Ok, now install an older version of uccnc from the recommended range of the 2017 screenshot website, in another folder, enable and test the plugin (setup the axis and estop and probe ).... Now add a clean install of the 2017 screenset.... Now try again.... Does the probing work or not?
There's only one current release that supports the UCR201, version 1.2049.
There's no reason to try any other versions, as they would be test versions.
Again, CNC Drive has had two different people test with the same setup, and can not duplicate the issue.
