Had my CF-pro running for over a year without any (non-user) related issues. Recently the THC stopped functioning, torch would fire for a second and FC would throw an alarm. Went thru the support and did all the continuity/voltage tests and ended up getting a new main board. Swapping it didn’t fix the problem but what did was installing the adapter to remove the ground plug from the PC. Just an FYI for those like me that went thru the forum when they first set up their machine and seen it mentioned a lot but didn’t bother cuz it worked without it. Would have saved me a bunch of time and $55…
