Print Sequence: One at a Time does not work with support blockers

[coderforlife 0]

When using support blockers, printing one at a time doesn't work since Cura considers the support blocker a separate object, even when grouped with an object, and refuses to slice.

Never mind, it was because the build volume height was lowered due to the gantry collision thing, even though I only had one "thing" it was already lowering the height.

 

Followup: is there a way to force it to move from the front to back when doing one-at-a-time so the gantry height isn't an issue for my printer?
