@Gary_Hangsleben I’ve got an independent 4” 110vac cooling fan blowing across the entire board. (Stole it off an industrial box I was scrapping) so I’m assuming cooling isn’t the issue?
Never had much freezing, but I have had only bad experiences with the Panucatt boards.
My X3 came with a bad H-Bed fet and my first X5 was DOA. Took a month for a replacement for both. About to buy a Duet when I can afford it.
