I’ve been having an issue with a print for days. As I show in the laminator, the walls of the file are completely flat, but when I print it, around layer 22, it seems to shift out of line by about 0.01mm and continues printing there, creating a sort of step.
I thought it might be due to the transition from the first solid upper part to the vertical walls, but the last two top layers are already printing out of alignment, and I don’t know what else to try.
Well, check that thread, I can almost guarantee it has the solution. This is a common issue when you have a base layer that transitions to walls, the difference in the amount of material can create different cooling times exacerbating the issue.
That’s what I thought because I believed the step was forming on the walls, but it actually starts happening in the last two layers of the large base. Moreover, it also happens on the other part of the box, which is completely rectangular.
Besides, the printer I’m using is only one month old, but the same thing happens on the other A1 and on two A1 Mini printers I’ve tested. It happens on all four of them!
Sorry guys, I’m not able to find the actual post I’m after and I don’t remember the specifics of the solution just that this is common.
If I find it i’ll post here otherwise someone with more experience will hopefully happen along. Include your .3mf if possible so anyone that comes along can examine it in detail.
Try increasing the thickness of the outer layer to 0.6 instead of 0.42… Print only up to just above the problem and see if that discrepancy still occurs… I have never had this problem even on my printers that I built. In my opinion it is not the problem of the Benchy waterline, I have already addressed the discussion in another post where it was not resolved in any case despite many claiming that it was the Benchy waterline… Make sure that the elephant foot has not been modified and check that the first layer is not too crushed. Can I have the stl file to try printing myself?
Okay. I have a few things to say after trying to print the model. According to my tests something is wrong with the design. I sliced the model and analyzed it and found that the first layer had some bumpy areas… I deleted the first layer and re-sliced the model and the first layer was fine. I did a print test and it didn’t work, the anomaly occurred. I tried to place the model with the vertical side on the print bed [that of the hinges] and also in this case a small artefact is present, mmmmm… I measured a bit and discovered that the anomaly occurs in conjunction with the upper plane of the model, both if oriented on the bed as it is loaded and on the vertical side on the print bed. where the model plane ends the anomaly is also introduced. I printed the model with my Voron and even in this case the anomaly is present but evident. I printed a Voron calibration cube and the anomaly was not present. In this case the only thing that comes to mind is the gcode of the model has a problem, otherwise it can’t be explained. So in conclusion, in my opinion the problem is given by the drawing and not by the print settings or by the printer itself…
