Thanks for the tips.
The top right one below is the best one I have done so far.
80mm per min, 10deg 0.1mm bit. I told FlatCAM that it was a 0.15mm bit for the last one, to try to give some more space around the traces. The bottom two kept cutting traces out.
Here is a zoomed in picture.
The yellow boxes show some super narrow traces. Red boxes look odd due to the flash, but it is a section that is not cut all the way through. The picture shows the edges where it did cut.
Going to try a different bit out tomorrow. Been using the cheap bits I got off amazon, which several of them you could visually see spinning off-center. Picked out the 6/10 that looked good, seems they arnt quite good enough. The set from Inventables seems to be better, going to see if that gives the needed edge to get those small traces.
