The printer stopped after ironing that layer, and told me the print was done, even with more layers left to go:

this happened to me with the and I reprint the file and it worked. So seems its a software glitch

sorry meant to say A1

Yea, I think in my case it was an AMS issue, I swapped the board out and it’s not done it since.
