I think this was the last update, see the last post:
viewtopic.php?f=2&t=240&start=50As you can see the last update appears to have been the beginning of 2020, and not even minor bug fixes since then.
I reported a flaw in some programming of the pendant over 2 years ago. It was acknowledged, but all I ever got was assurances it will be corrected, etc. Here I am, all this time later and this minor issue still not corrected, after asking about it several times.
One can not be blamed for thinking any further development of UCCNC has currently stopped.
I still come to this forum to keep up to date with any useful knowledge, just in case one day the development of UCCNC commences again. However, as a safety measure I've started learning a different platform.
