Just a guess, you’re using windows 10 ??? I’ve read in here of people having problems when updated their windows automatically, maybe it was flashed with the newest C3D version which seems to me to have been the culprit since Bill Gates won’t allow himself to be blamed. Can you verify what grbl version or CC CM version I meen, see I really don’t know just guessing and trying to help. Search for the newest C3D programs and problems. New board makes sence they sent it with the newest program… Good Luck… more reasons I like the other program… Jude ps this topic - 100 posts
