Hey @DavidYon47, for best results with fine-pitch printing, I'd suggest the following:
1) Change the Pass Spacing parameter for Conductive ink to 0.15mm, found in the settings window (leftmost column).
2) Change the Print Height to 0.08mm, down to 0.06mm if you're trying really tight spacing.
Other than that, you should be fine to print as normal. Good luck!
