I have a Prusa MK3S+ with the stock extruder and it seems like my blob is printing too far forward on the push pin top so the mechanism never hits the blob to push it out.  Picture attached. Any advice appreciated.

Hi @dvanderb
It looks like, for some reason, the nozzle is more forward than expected.
I've attached a couple right side bracket variations. 2 and 4 mm.
They will move the RPM toward the front of the printer.
Please let me know if either fixes the issue.

Thanks. It may take a few days but I will give it a try.

I am happy to report that the 2mm variation solved my issue and I was able to perform 5 successful purges in a row(the blob actually ejected on the first strike each time).
