So other people and I have been trying to help someone pretty much all day. The issue is extreme layer shifting on the x-axis and it’s ALWAYS to the left. We’ve had them do everything from tramming with 123 blocks (knowing that wasn’t the exact cause but just in case) to swapping rails to making sur…

Looks like an intermittent X motor to me

That was the initial thought but as the x rail was swapped out with a z rail it still happens the exact same way.

Ok so update on his issue. The firmware is refusing to update, it froze during update. It sat there for a few hours updating firmware, finally he shut it off and back on which we know is a bad idea but it was the only choice as it was stuck. So I’m more convinced that somehow his firmware got corru…

[image] Artezio: firmware has been updated, rails have been swapped out multiple times in multiple combinations and it’s happening the same way You mentioned that the shift always in the same direction. That is quite strange. If the model always shifted in one direction, this issue has nothin…

I can’t attach the gcode it’s too large but here are the pictures and stl [image] [image] Radiant_Blossom.zip (2.1 MB) The base always prints fine except for on the left “foot”. It goes wrong when it gets to anything above that. I agree there’s something wrong with the stl, it is manifold but t…

@Edwin after all of this troubleshooting I think it may be the controller. it fails at random, but almost always on larger taller prints. With small items it rarely fails and with how many times the X-Axis rail has been swapped out, the likely hood of it being a rail problem is extremely low. I have…

Thank you so much for your updates. I just downloaded the STL file and generated the G-code with Snapmaker Luban in the Fast print mode. I do not think the problem relates to the controller, it will not fail at random because we have not received any similar cases. Because the model is hollowed, …

Latest update: We got the cube to fail. Scaled it up in Luban to 150% and it failed. Retraction, retraction at layer change, and z-hop we’re all enabled. It seems when an object is over a certain size it has a tendency to fail. Now I am suspicious of the head itself. As retractions and z-hop were al…

Any idea what causes this extreme layer shifting?
