Most slicers allow you to move the object in the Z axis, so that it gets 'cropped' below the bed. I did a quick trial with Creality Slicer 4.8 and I was able to move the Z by -30mm so that it only prints the top of the object.

Yes, thank you I discovered that. I think I still need to learn how to use a cad program though. I spent ten minutes trying to figure out how to cut the model with csg in freecad but couldn't quite get there before I decided I'll come back to the cad stuff tomorrow. I mean just using the gcode or some calipers to measure the piece then dropping the model in the slicer software by that offset on the z plane is quick and easy. I do wish the print could have continued from where it was. I don't know why it refused to run the print. I told it not to calibrate and just print but still failed.

How would you go about bonding the pieces after? In my case due to the way its cut off i will have 3 pieces printed seperately once i've run this through the printer. Im thinking strong adhesive or would you melt them together?

I would probably go with glue.

I'll give it a go! I've tried using my hot air gun yesterday for fixing something but there was some warping. i used it with less air while it was still on the bed this morning and fixed an issue before it became a problem but that wouldn't work for bonding two pieces. I guess i'd need to burn something as I'm pressing them together but glue seems easiest.

(Asked by: username_0 on 2024-06-26)

I tried to fix a very minor stringing during print and I accidentally bumped the head. As a result, it's now offset and printing spaghetti. I want to save the print but I'm new to this and I'm not sure how to go about it. So far I've simply taken record of which layer I was on though I'm not sure how far into that layer I was. I've also removed the stringing and gently filed with a small file from a fingernail set.

How do I save the print? the piece is still pretty much as it should be, definitely reckon it's within error margins. If I could align the head accurately and resume print from where I've paused (or preferably from slightly before that when I bumped the thing) then the print could probably be completed successfully.
