First the obvious, it is high quality filament and it is dried. Cracked open new rolls and rolls of different colors, all dried. Still get buildup on nozzle and end up with horrible malformities and have to ditch the prints (every other) as some are beyond usability.
Howdy mates, suddenly starting to get blobs on the nozzle printing out the same PetG brands I printed out since the dawn of my dual X1C’s. (Easily have +700 rolls PetG through the set pair, maybe a few rolls other filaments the first printer/first week.)
For settings I have run over 700 rolls with 3-4 walls, 25% infill with the only real toggled alternative support or not support and different kind of supports if necessary. Standard speed, pherhaps 2-3 rolls on Sportmode for the heck of it to impress our buddies to upgrade to Bambu printers. But nothing more exciting than that, not that I can think of anyway. Mostly been interested in great print qualities so thats about where stayed within my comfort zone/limits. And it worked so far…
Interlude;
(In case anyone notice my recent post. Dont think its relevant but both printers literally suddenly made deep scratches in my golden textured plates just recently like a MONTH back, but I dont think this was related to the blobbing on the nozzle issue NOW, posted aboot and solved separately a few maybe 4-6 weeks prior to this blobbing issue were adressing now. Rolled back firmware, reboots asf
Full maintenance done, new 0,4mm bambu original nozzles with brand new socks and yet another set nozzles now. Sry pherhaps writing poorly, decked in migraine since thursday.)
Back to issue
They both started behaving this way at the same time a couple of weeks back.
Pre-emptively dried and tried eSun, Stronghold, AzureFilm, Radius, RED and Sunlu and ALL with different rolls/color within each brand…
Might add blobbing occur in both current and prior firmware, using the standard setting 0,2 OR my tweaked setting for each filament. If temp is the issue this it is so both in prior and current FW and in different nozzle settings, standard and fine tuned settings, also occuring in both printers at the precise same time. Feel like I’m missing something bloobby obvious, but like I said on a migraine since thursday. So mates youre definitely the bosses of these printers and printing whatsoever at all, nothing you cant figure out (learning from this awesome forum) and I really need your sharp minds if you so kindly would share your thoughts or what next step you would take?
Thus I turn to you mates, am at my wits end, and I need your expertize.
How do I solve the blobbing issues and make them behave as wonderful as they have up till recently?

Oh yeah, other random details;
Drying with Sunlu and dual Eibos filament dryers @ 70Celsius and both are modded and motorized to spin the rolls, I do about 10hrs drying time. It is below minus - 30 C outside and running an EESE air dehumidifier so the air is insanely dry indoors. Were talking lips and fingertips cracking and dry tongue dryness - which pherhaps helps the drying speed further. Oh both dryers are modded with airflow type modest to assist drying procedures.
Also I only own 0,4mm hardened steel original bambu nozzles (About 20 complete sets, and I additionally swap silicone socks pre-emptively since this clearly is an issue that can cause nozzleblobs)
I checked that it bambu studio is set to 0,4mm nozzles and PetG,
I use the original bambu settings Standard 0,4 or Strong 0,4,
I also have a tweaked profile for each filaments brand & color’s flowrate.
However now that both has gone wild I opted to return to Bambu PetG Standard that always has worked on both printers flawless. (The tweaked flowrate profiles only helped getting supersmooth print surfaces and some better overhangs, in particular supportless overhangs)
I toggled back to the previous firmware through bambuhandy,
I toggled back to the firmware previous to that also.
(3 different firmwares if counting the latest)
Erased Bambu Studio and re-installed bambu studio.
Obviously I very early zeroed all settings to factory so I would not miss anything underlaying hidden settings, and just fixed settings that I know and that has worked all the time up until possibly now.
I have done no manual tweaking of the G-Codes or anything I am an ignorant tard aboot.
(I have had thoughts about doing the Scrubbler 3.4 wiper mod and copy and paste the suggested g-code in to my printing profiles, starting with one to begin with. But have not done that yet and only come as far as thinking about it, so hopefully my beloved X1CC’s arent clairvoyant I hope thats not something to take in regard.)
Out of all the brands of PetG (And I believe I have tried any and all that are of quality brands) my printers has loved chewing on Stronghold the absolute most despite their pricetags and nonexistant sales. So my latest attempt is I cracked a brand new roll of yellow Stronghold PetG HS and put it in the dryer for +20hrs (had it set on 24, but I got impatient) and corked it in to my first X1C that has been acting up just a tad more than the latter, newer sibling. The above dried roll made a print that virtually just popped out as grand on the below pic…
And that is where me, my migraine and my twin set of beloved X1CC’s are @ right now in this point of time and geography…
Sure could use your help mates! And many thanks for writing and commenting and helping out with hints and skilled knowledge!
