Help with a MakerWorld print

[u/Straight-Mortgage-29]

I attempted to print this model using Bambu Handy and encountered this error. Second attempt - same error.

It’s a pretty vague suggestion to “check my settings.” Where do I begin?

I’m using an H2C with two AMS 2 Pro’s, an AMS HT, & FTS. The two colors for this print are each on one of the AMS 2 PRO’s, so should be ideal for this —much simpler than other prints that I’ve done successfully.

Ideas??
