I have a design that I have printed successfully probably 100 times or more. Suddenly, it has stopped printing the small circles at the very top of the print. It isn't obvious from the picture, but there are multiple standoffs, so there is travel between each layer of the standoff being printed. Any tips on what to try to fix this are appreciated.
Monoprice Maker Select v2
Cleaned, then replaced the nozzle. New PTFE tube is on the way, but current one looks fine.
Tried extruder temps from 190 - 200, 200 is what worked originally
Tried 3.5 mm retraction, then 2.5 mm. 3.5 mm worked originally.
