... follow up. Instead of trying normal supports, I saw there was a CURA 4.11.0 available. So I upgraded and am trying tree support again.
Well, the print has gotten past the point where it was failing before. So it looks like things are better. Also, I noticed that the computer had a problem mounting the SDCard the seconds time. Indicating I may have pulled the SDCard out before the file was completely copied over the first go around. So it may not have been a CURA problem. Unless I've another print failure, I'll leave it at that & assumed I didn't un-mount the SDCard properly.
