Sorry for the confusion. I changed the topic title to more accurately describe what this post is about.
I see what you’re saying, however, that’s already possible and it’s not what we need. Let’s say you have a 50 layer print and you want to embed something in the print. Maybe a nut, or some weight. What I want to do is print layers 1 to 20 of multiple copies of the object and instead of pausing, I want the print to end until I can come back and add the nuts or weights. Before I get comments about the print coming off of the bed because it has cooled down, I’m printing TPU which will not come off of the bed even when it has cooled down. So, after adding the nuts or weights, I want to start the second part of the print from layer 21 at the height the previous print stopped at. Of course I would make sure that there’s a “landing zone” for homing where the hotend will not crash into the parts already printed and I leave bed levelling and flow calibration turned off.
