I’m glad I’m not the only one that feels like this is an H2D problem. I have 3 X1Cs and never really had this issue so pronounced. While this has happened on my H2D from the very start.
Side note: here’s the finished Hat (blue TPU). It’s pretty comfortable for being plastic.
is the final product also printed on the H2D? It doesn’t look like that it’s printed on the same machine to me. There’re quite a lot differences here, the slicer settings are definitely different or it’s just the lighting playing tricks on my eyes.
But cool model! Facinating.
The hat crown (blue TPU) was on the H2D.
The bill (brown Matte PLA) was on the x1c and I put like 10 magnets in it.
The bill accessories was also on the X1C and is all PLA.
The topper as well was on the X1C but this one I used 7 PLA colors and PVA for the first time (tried to model the milkey way Galaxy 
). It’s sitting on a ball bearing.
Actually had something similar happen to me today. This was a very large box out of Bambu PLA Basic. Right when it got to where the interior structure of the box was complete, an offset line appeared on the outside, very prominent on one corner and then fading around each side to nothing on the back corner. Not sure if it’s the same issue, that’s what I came here searching for.
really cool model. sadly it requires dual material support so probably not so realistic to print with x1c to test.
it really depends on the geometry and the slicing, there’s no way to get rid of that line easily. You can slow down the printing to make it less pronounced, you can use inner-outter-inner wall order, you can use gyroid to improve shrinkage resistance, but it’s always gonna be there, as long as there is a bridging surface large enough closeby, regardless of FDM printer.
In this model it’s more pronounced on the front left corner because it’s having a large bridging surface at that corner; while in the back the bridging area is much smaller and takes much less time to do it. The extra cooling during the bridging is the reason this happens, there’s no way to get around this without using fibre reinforced filaments.
Actually I tested the hat crown on my X1C first bypassing the AMS. I designed it to not need any support.
The X1C crown turned out alright. I had a lot of stringing and not the cleanest inside but it still worked well. The TPU was in a dryer the whole time.
I redid the crown on my H2D with pla as support and the result was as close to flawless as I could have hoped for. Though the pla was a pain to remove.
UPDATE with pics:
I stand corrected (at least for the issue on my hat)! I think there was so much mess on the X1C print that I didn’t notice the layer shifting. Now I feel like the H2D is sooo good that I am noticing the little details that were obscured on my X1C.
Though the others posting similar problems might be a different issue. TPU is a different beast to print with. Next time this happens on one of my PLA prints that isn’t bigger than the X1C build volume I’ll test and update here.
Thanks for all the discussions/help.
I’m not sure I understand. I’m not bridging anything at this point. I’m just going from a larger volume print to exterior walls of a box. But, it was also evident in the lid of the box. The same issue arose in the same area once the lid’s “solid” space was done and it transitioned to the rim of the lid.
I don’t want to hijack this thread. I was just trying to add if it helped. I’ll start my own thread.
I don’t mind a little hijacking. If you start a new thread can you link it here? I’d like to learn more about the offsetting you are experiencing as well.
That’s what I expected, the H2D would still beat anything on the market right now (though, far from being perfect 
this is exactly what is called a benchy hull line issue, search for it.
I cannot share the files.
My friend, the designer of this part, has printed QTY35 of them on his X1C’s without the layer shift.
The second picture I have printed QTY3 of them, and only one had the layer shift problem.
This is absolutely the same issue.
your issue is completely different from his. I don’t know why it’s happening on your device, but @colonel0000 's issue is completely different and it’s classic benchy hull line.
No it’s not.

@colonel0000 's issue is classic benchy hull line (meaning that if he print the model again, the same issue would happen on the same position), yours are appearing on non-hulline affected area and randomly, so no it’s not the same issue.
I’m going to leave my erroneous comment above, because I don’t believe in changing my initial ignorant response when I’m incorrect. I see what you’re talking about now.
Well, I’ve never had this issue with either of my X1’s. I also found it odd that it’s prominent in one corner and then fades as you go around instead of being consistent all the way around.
just try print it.

It’s too big for the X1 bed.
