Any way to print with a "no-go" zone?
I'm trying to insert a bearing into a print. The problem is, the inner race of the bearing is wider than the outer race. When I drop the bearing into its hole, the inner race protrudes 2mm over the print, meaning that the nozzle cannot pass over the center of the part, or it will collide. It will need to seal up the bearing only "coming from the outside" until it has cleared the 2mm.
Physically, the nozzle and hotend has room to do the job. But I need a way to avoid the nozzle crossing over/moving into the center when traveling.
In some ways, it's like sequential printing with a non-printed part. Any tricks I can pull here?

In the end I went with hand editing the gcode. Which works, but is a bit cumbersome.
"Avoid Crossing Perimeters" does what it says most of the time, but not when changing layers, so I had to manually reposition on layer change.
I guess I can conclude that there's no "tricks" to this

Trying to visualize what you're trying to accomplish... Can you post a 3mf/stl of the design (or the relevant portion), or a drawing?
RE:
The blue inner circumference is the pause point, where the bearing is dropped in, and the ID of the part shrinks a little to seal it. At that point, any travel paths crossing over the center will collide with the inner race of the bearing. I need the slicer to build 2mm from that layer without traveling over the ID, it will need to "take the long way around"

Here is an extended inner race bearing. Though mine only extends 2mm on the side oriented up after dropped in.
RE:
Have you tried "Avoid Crossing Perimeters"? But this doesn't always exclude all travels across the inner diameter. Also, there may still be interference between the sides of the nozzle and the protruding bearing unless you make the ID wide enough. I wish I had a good idea.

This may be a case where you have to design the print to be split and fastened together.
