I have the same problem. Tried a number of different things. Seems like a design flaw to me. Has anyone tried different extruder designs?
Have you read through this thread?

Re: Avoiding Hairballs with PETG?

It used to stay put, but with plenty of use, cleaning & lubrication, it coasts very slowly down to the bottom. If you stop it, it will usually free fall with the slightest vibration. it doesn't seem to affect anything (other than the hairball problem with PETG), and I just view it as a sign that it ...

Re: Avoiding Hairballs with PETG?

In the absence of any suggestions or feedback, I did some digging into Marlin G-code options. I haven't tested it yet, but I'm going to try adding an M109 "Wait for Hotend Temperature" command to my ending script. I'll drop the platform a cm or so when the print is done, and then wait until the hote...

Re: M2 nightmare with soft filiment

Quick update: I installed the filament drive with the grooved sleeve today when it was time to install a new roll of filament. I've been slowly using up a spool of PETG on various small prototypes, and have been tied up a lot on the CAD end of things, which is why it's taken so long. The drive insta...

M2 Rev F vs Rev E Differences?

There was a posting in the dual extruder forum about someone who recently purchased a "Rev. F" M2 printer. I have a 14 month old M2 Rev. E, and I'm curious what the differences are between the two models. Mostly I'd like to know if there are any of the upgrades that I might wish to install on my old...

Re: can I use glass plate with Kapton tape down?

I regularly flip mine over to print with hairspray on glass for PETG, but you have to be careful about leveling. The glass isn't perfectly uniform in thickness, and if you are unlucky, you may have to re-level when you flip it. Mine is tapered front-to-back, but not very much side-to-side. As a resu...

Avoiding Hairballs with PETG?

Anyone who has used PETG knows how stringy it is. I've been using it a lot, and the prints are coming out fine, but I just discovered a minor issue. My ending script retracts 15mm, shuts off the extruder & bed, lowers the print bed a ways, and then shuts off the motors & bed fan. Now that my M2E is ...

Re: nema17 dampers

They are presumably fairly standard, so there is always the option of finding a higher temperature rated stepper. At least now we have the specs.
