I use hair spray on the print bed for sticky filaments.
so i may have found another reason why i have issues with my PETG Basic, after 900 Hours of printing, maybe it is a good idea to clean the extruder gears and lube them again 
Is this a maintenance procedure? I’ve never done mine.
Depending on the hours yes
Thanks, think I found the wiki for the H2S. I don’t suppose you have the procedure for H2C please?

this is the best i could find, it hopefully helps
The PETG Basic prints fine on my H2D with the standard profile on the Cool Plate Super Tack. Releasing the parts is no issue either.
Quality of the print is fine, but I am disappointed with the surface texture.
Where PETG HF had a nice matte finish, PETG Basic is almost back to the high gloss known from PETG in general.
I know PETG HF misses some strength, but my goto PETG HF was mainly for the temperature resistance over PLA and the nice matte finish similar to PLA.
Bambu says that PETG Basic is the improved version of PETG HF but it’s just PETG (which is already around for a decade) to me.
I don’t know if they have issues with their supplier, but this is definitely a step back in my opinion.
I am definitely going to look around for something with the same finish because I simply don’t like the glossy finish.
Slightly less glossy than Standard PETG but still too glossy for me.
I use my old plates that don’t work with PLA, it’s perfect for TPU and other sticky filament.
How are you drying and storing it?
i dried it in my AMS 2 Pro 65°C for 12 Hours and its also stored in the AMS
Reason I asked is the photos look something like the issues others see when the filament moisture content is too high. PETG Basic is new though so not much track record to really know.
If you take that spool (hopefully over 1/2 full still) and put it in a ziplock bag with a hygrometer and seal it, in an hour you should have a stable humidity reading. That would give an idea of how effective drying is going and could help narrow down what’s going on.
Just not much info yet on how much moisture causes problems with PETG Basic. I ran the test with PETG HF and found the cutoff for me was around 20% RH with it. PETG Basic is likely similar but can’t say that for certain.
Ive had my P2S for a few months now… Only ever printed in PETG-HF. I have had to start using the Basic, and Im really not a fan. Its very glossy, and I much prefer the matt look of old HF.
I’ve got a couple of rolls of the new PETG Basic on order to test, but based on what I’ve heard I’m not optimistic.
I hear Sunlu has a good matte PETG but I haven’t looked into it myself.
With the printer knowing what material is going through the heads for how many hours , one would think the firmware / slicer could display maintenance interval messages based on actual usage.
It’s not that bad so far for me and is actually pretty good. For printing aesthetics with the limited experience so far, I do prefer HF over (new) Basic, but Basic is printing quite nice and very reliably. 1st layer puts down excellent.
I’m very curious how others make out and how susceptible it is to water.
How is it for layer adhesion and flex recovery?
I haven’t tested or compared those to be able to say but there’s nothing I’ve seen to indicate issues.
In normal handling so far and cleaning up support on the parts I’ve been printing they all seem quite strong but nothing quantitative. Just two spools of white so far too. Not tons of experience with it yet.
I’m another 2kg into it, and with outer wall set to 70mm/s, the overhang gloss is still more shiny than vertical walls, but it’s pretty close that I wouldn’t notice unless I was looking for it. There was a tiny bit of stringing and blobbing but not more than with dry PLA. Here are more pics. Dark Brown is Bambu PETG Basic and blue is Prusament PETG (Chalky Blue), they seem to perform similarly (in appearance anyways).
