I know the layer it failed, how do I start there.

The error message i got noticed that I wasnt laying down filament at layer 520.

I can go into the software and go to that layer, plaus a few layers previous to ensure I get the missing layers.

How do ibtell it to make a new print starting at layer 515 so I can just glue them together.

In preview I can see exactly where I need to cut it. I cant bring this information over to Prepare as far as I can tell and I dont want to eyeball it.

What steps do I net to take to cut the model right where I need to to print just the missing part?

If you’re planning to continue the current print..Not going to lie but I don’t think it’s even possible (well…It is but from what I’ve heard, it is quite difficult as you have to root the printer and modify several settings…)

However, you can try to cut your model in half (at layer 520mm, check the mm in Preview and then cut it with the Cut function) and then glue it to the bottom half you already have :slight_smile:
