When I do multicolor prints, there are inconsistencies in the layers due to what I assume is the quick-slow-quick-etc pattern that the print does.
On layers that contain 1 color, everything is normal, but when it gets to the 2 filament color layers, every other layer is different. Am I wrong and is it from the 1st filament not getting flushed enough? Because using 800 or 999 flushing volume doesn’t fix it.
What I assume is happening: the filamentcolorA part of a layer prints, then it long flushes, then it prints filamentcolorB on that layer, then filamentcolorB on the next layer, it long flushes, then filamentcolorA, next layer filamentcolorA, flushes, filamentcolorB, next layer filamentcolorB, flushes, filamentcolorA, next layer filamentcolorA, etc. And because it prints two layers of the outer wall without flushing, time passes, then two more layers, it causes these inconsistences.
Is there is a way to make it print A, flush, print B, flush, next layer A, flush, B, flush, next layer A, flush, etc? This causes more waste but fixes the issue.
Or is there a way to make the printer wait after every layer to make the layer time equal across the entire surface?
The only “fix” I have found is making every layer of the object 2 colors so it’s consistently inconsistent throughout the whole print.
Has anyone else had this issue?
My settings: The whole object has the exact same outer wall speed (35mm/s), fan/aux fan speed (100%/70%), temperature (225), and flow on the outer wall. The only difference on the outer wall layer lines on the preview is with layer time (which matches up with the inconsistencies exactly). I print outer-inner-infill, rear seam, 3 walls, 8% gyroid, 0.2 layer height.
I have tried to print at low temperatures + high fan speeds to try to cool each layer as fast as possible. I have tried low or no fan. I have tried higher temperatures. I have tried very slow inner and outer wall speeds, as well as messing with extrusion rate smoothing. I have tried fast speeds.
It’s causing me stress and I’m not really sure what to do and would greatly appreciate any insight anyone could offer. Thank you.
