RE: Filament lines where they shouldn't be what causes this?
Yes I agree with the black is very hard to see. I saw that trying to troubleshoot this. Thank you for you help I will look at those things and I thinking the same it's the nozzle of extruder on that color.
After looking at the Slicer file, I'm guessing tool 4 bed level messed up (nozzle not clean?) or there was an extrusion problem as that color started printing. The result being the second or third layer of orange started printing in the air. Any chance you recall if the purge tower looked normal? Especially the orange?
In either case, I'd expect the orange bits to pop off the print pretty easily since they are only tacked down in a few places.
To test this theory, in Slicer, cut your part so that there is only the very top layer or two of color, slice it and print it as a multi-color test. If orange isn't sticking, or printing in the air, the culprit is tool 4 or its calibration.
ps: One suggestion for future reference, when you want black filament represented for a tool, make it a dark gray; black is nearly useless in the gcode viewer. A dark gray allows looking at the lay up.

Purge tower looks normal. And nozzle 3 is the problem. I am going to change to colors around see if the problem follow nozzle 3 also.

An edit didn't make it in time. Yes, tool 3, the orange. tool 4 has the black color I had to change to look at the gcode.
I still recommend you do a simple one or two layer print of the colored top most layers - that will be a quick test of the hardware.

ok.. I will and let you know.. thank you.
