Over retraction issue
I appear to have a problem with the extruder over retracted and then not printing. I can see it retracting back after completing a fill, but it appears to retract too much. This only happens in certain places of the print.

Any ideas why?
I'm printing standard PLA with standard settings.
Printer is a MK3S+ with MMU3 and a Revo hotend.
I've tried a new nozzle, stripped and re-assembled the extruder, re-sliced the model in different versions of PrusaSlicer - yet to try throwing it out the window.
By the sound of it you have a partial clog and/or a wrongly set extruder idler pressure.
Try a cold-pull and if the problem persists look to your idler pressure.
Cheerio,
