What size nozzle are you using? Also have you messed with extrusion settings at all, especially amount? I feel like the previous advice had you change an advanced setting when you’re dealing with a basic setup issue.

0.4 mm.
I mess around with one setting at a time, to find out what each of them does in isolation. At some point I will look into calibrating the rate of extrusion. But for now, I’m playing with simple options.
Also, it’s not a piece of art. This is a piece of equipment for the shop floor. It’s already plenty good enough. I’m just curious how to make it better 🙂

Just checking on things, no offense intended for anything I asked and I apologize if it came off that way.
The voids we’re seeing look like possible under extrusion and I didn’t see that mentioned before. If you haven’t changed any of those settings that is likely not the issue. All of the printers I’ve worked with do just fine with default settings.
Do you have infill set at 100%? I may have missed that detail. What pattern is selected for the infill? Some patterns work better than others.
How tight are the rollers for all three axes? They should be just tight enough to prevent any wobble in each direction. Too tight and the print head might be restricted.
Last thing for this round: Since you’re getting smudges of the other color, your temps may be set too high.
Just some late night thoughts for now. Hopefully something might ring a bell.

The voids comme from the arachne perimeter generator - since that’s what the slicer uses in the letters, because they’re too small to contain anything but perimeters. You can even see them in the slicer’s rendition:

There seems to be a way to eliminate then - in the slicer anyway - by increasing the perimeter transition threshold angle from 10° to 40°, but I haven’t tried it yet:

One-wall looks better anyway, so I’ll try it again, without ironing this time.
