So I set this text to change the bottom layer to concentric only for the text and I got this. I had this large flat area in my print and decided to spice it up a bit for fun without doing multicolor which would be 1, too annoying to do manually and 2, too visible for this part that needs to be all black. So here I have a nice DON’T PANIC on the back of it.
Z offset like you mentioned is probably wrong, extrusion multiplier is probably wrong, extruder might be incorrectly calibrated, PA is definitely wrong. It really looks like it hasn’t received any tuning at all and this was just done with OTB defaults.
