yes, as I said earlier feeder is so strong that can rip some parts of filament.
I havenât seen the inside, someone posted a pic but parts were missing.
Anyway, is there a way to adjust it somehow..is there a spring..??
I fixed the issue with the filament feeder. 3Dprintdemon (see GitHub) has added support for the max in his klipper essentials unified macro pack. After spending a couple hours setting it up, the filament feeder doesnât feed so strongly with as much torque as it did. Itâs almost like it ramps up the torque so that it doesnât tear the filament and doesnât trigger clog detection. Iâve been printing consistently for days now.
I also modified the feed detection where the filament comes out at the top that seems to have resolved a few false positives with clog and tangle. I removed the spring underneath the shuttle that moves back and forth and installed the shortest m3 socket head cap screw I had. The m3 screw just goes into the end of the spring as a spacer because in my case the shuttle wasnât returning completely a large percentage of the time. With the m3 as a spacer, the spring always has a bit of tension and the shuttle always completely returns.

I had different problem. I have filament that is a little bit rough, has more grip than e.g. Bambu or Sunlu but nos as much as PLA Glow. The feeder cannot even grip on it, because you know circumference times length is merciless on MAX.
So I create this monstrosity but it seems to work:
I did remove external feeder references from macros. My next step would be converting feeder to just second extruder working in parallel with toolhead extruder.

That is not a monstrosity. looks like an elegant solution as long as you donât need a top panel.
Any chance you could share your macro file, or list the macros that need to be modified? I just got my SV08 Max set up and did an 8hr test print with a false clog/jam error.
I want to just completely bypass/remove the feeder to avoid any further false positive errors.
Go to 3Dprintdemon on GitHub. Thereâs an entire installation procedure for his klipper macros and theyâre amazing. There are some sv08 max steps just for our printer too.

Unfortunately Iâm out home for a weekend Iâll share it with you on monday.
@joeadops Yes, but this repo consist of a lot of changes. I changed one thing because I wanted only to disable feeder.

I had random issues with the feeder falsely detecting tangles because it was sticking. I disassembled and lubricated the sliding mechanism with a dry teflon spray then added the 3Dprintdemon guide recommended by Lion, which serves to better keep things in line. No more random false positives from the sensor.
The guide and macros from 3Dprintdemon make the feeder work properly so you donât have to disable it. Itâs worth it.
If you carefuly read my issue you could understand why I wanted to disable it. PTFE tube is to long for rough filaments.

Compare against your files and replace only feeder references.

Thanks! This stupid thing keeps grinding up my filament, making terrible noises, and throwing false jam errors.
I setup the DKEU macros in hopes that would smooth out the feeding speeds, but itâs still just as bad.
Check out my comment far anbove about the m3 socket head cap screw I installed as a spacer in the shuttle spring. I was getting false positives at least every 10 mins because I noticed the shuttle after being pushed up when filament was fed that it rarely ever returned completely to trigger the filament feed again. The spring Sovol used for the shuttle is too short in my opinion and it relies on gravity to fully return the shuttle back down.

I have the jam and clog detection pins switched off thanks to the DKEU setup, itâs still just grinding like crazy. My machine is covered in PLA dust thanks to it.
I wish they would have just left it as an optional feature (flaw) instead of sending it out with the machines
Have you checked that the bearing is not missing insidew the auxillary feeder? It was missing in mine and turned it into a grinder

Opened it up today, both bearings are there, along with a pile of PLA dust, haha!
I ended up adding the BTT SFS2 on a temporary crossbar (pay no attention to the wago connectors, I have a real jst extension cable ordered) after removing the filament buffer/feeder. Also noticed that the stock Bowden setup had A LOT of resistance, guessing from the length of tubing and all the connections.
This setup seems to be working a lot better now with the shorter length of PTFE tube. Might work with the buffer reattached and relocated (using a can bus extension cable) given that the stock tube length resistance might have been adding to the filament grinding issue.
I think that you may be interested to check out my topic 
. I did similar thing but with SOVOL Max feeder:

The Capricorn tubing designed for the Bambu AMS is so much better than what ships with the Max, it alsohas a much wider inner diameter and has almost zero friction Capricorn Premium PTFE Bowden Tubes for 3D Printing
