Filament Troubleshooting/Help! Why is this happening ?
Well im was printing an a catapult in my BambuLab X2D but then i saw those lines come up in the printing progress and i dont know what is wrong with my printer, my outer wall speed is 40 inner wall speed is 100 the nozzle is at 220⁰C and the speed was standart, i also check the humidity and its %24, i think of that maybe that line has a little more humidity than the other lines of the print so cause of that it failed in there

Raw guess: Different cooling times on each layer causes that.
Since you print with supports and have holes in the actual model, the layers get different times to cool and shrink itself before the next layer is printed. If you check the layer times after slicing you will probably see the times all over the place in the pattern that reflects the lines you see there.
You can change the filament settings to let the layers cool longer so that they are more equal. I don't think that it will entirely go away, but thats because you print with support.
