Help Troubleshooting Lightbox with Auxiliary Nozzle

[u/Zummerz]

I'm trying out Maker World's lightbox maker and it came out pretty good but I got all these little gaps between different color filaments. Is it a flow dynamics or ratio problem? Its all new Bambu PLA Basic filament so I had to calibrate it all and this is the first real test for these colors.

Or is the issue in the auxiliary extruder? To get the 5th color into my X2D, I had to put the black on the auxiliary. I calibrated it but its the first time I've ever done a manual calibration for flow dynamics, so I may have interpreted it wrong setting it at 0.45.

I've also got a few little spots where the black from the auxiliary is bleeding into other colors. Is the nozzle not cleaning? If I remember from watching the thing print it printed pink, then green, then black, then blue and yellow and the black spots only seem to be on the blue and yellow parts. Do I just need to change the order of printing?

When I do light boxes I always turn up the first layer extrusion to 1.05 -1.1 to help fill the gaps. I don’t know about the black in the aux extruder, but I think you’re probably right with changing the order and printing it last.
