Hello, this is my first week 3D printing and I’m running into an issue that’s causing me some headaches. I’m parallel printing a tough part that’s unlikely to have a 100% yield under any circumstances. When I have a part failure on the bed and exclude the part in Fluidd, the printer will often make moves to the location of the failed part (this seems inconsistent or at least unintuitive). If the print-head moved at full speed, this maybe wouldn’t be an issue in and of itself, but the printhead seems to inherit the speed of the last feature printed (or maybe the next one, I’m not sure). This sometimes results in painfully slow moves to nowhere, all the while PETG oozes and drags over all the remaining parts and eventually webs up the whole bed. So a bed where it looked like I might get 50% yield after I get past the tough features turns into flat 0% yield in the last couple of layers.

Now obviously there are kludgy ways to work around this, but this cannot be the intended result of this feature, right? I understand that reprogramming a CNC path mid-process is no joke, but at least if the speed issue could be fixed, I think I wouldn’t lose every part on the bed.

I’ve seen other people have this issue, but haven’t seen any workarounds for it. Is this a known issue? Is there a tweak I can make to fix it?

Thanks,
Jason
