If you look at the sliced tool paths, what is it doing when it puts those Xs into your test print?
Sliced tool paths? What do you mean by that. I'm using Prusaslicer if that helps.
The area where it's layer shifting in the center of the boat, if you have some way of measuring that, divide by layer height to determine what layer that happened between. If the slicer is doing anything fucky with the tool paths than that may be a contributing factor.
Edit: Sorry, just realized that puppetx was talking about the box, not the boat
In your slicer, you should be able to "play" the gcode to show you step by step what you printer is going to do, for each layer.
In prusa slicer after you click slice you will be presented with your sliced gcode. At this point you can use the vertical scroll bar on the right (to pick a layer), and the horizontal scroll bar on the bottom (to play through the tool path (moves) for that layer) to see every operation your printer is going to perform as it runs this gcode.
If this was somehow caused by bad slicing/g-code it could be used to help troubleshoot it. But it sounds like others here have probably provided more insightful troubleshooting suggestions and you may want to pursue their advice first. Hopefully your tightened z screw solves the problem!
