Hey @dfrez
I recently got a roll of eSun PLA+ Grey as well, and noticed the stringing was so much worse than standard PLA (and I was having under-extrusion issues too which fits with your problems, but didn't notice that at first).
I did a full clean, replaced the nozzle with a new one, even replaced the bowden tube, still giving me hassle. I swapped back to standard PLA and that was totally fine. I specifically got the PLA+ because I was printing D&D minis and it was recommended because of the higher strength.
I have read through your posts and (even though I am using the standard brass nozzle not a hardened one) I will test the temperature sensor and then see if increasing the temp to 240 will help it print like normal PLA.
Thanks for your posts listing your troubleshooting and the updates, I hate it when people fix a problem or find an issue and don't update.
