AMS 2 Pro Motor Slip Error

I just got this error yesterday, the filament just reached the coupler, then it makes a spring or a stopping sound somewhere in the AMS unit and then retracted. Does it a few times and that error pops up. It did some damage to the filament where some parts of it is worn out.

Do you think this tube set-up maybe the problem as being too long and bend or something wrong with the motors in the AMS unit? I had the same set up for about 2 months with no issues.

I tried the following:
Checking for any clogs thru the tubes. None.
Running filament thru external spool holder - is fine.
Last filament used was PETG-HF 2-3 days ago.
Last modification I made was that bracket, I did tamper with some of the tubings. But I done a few prints after that, all came out fine; no problems whatsoever, printing and filament going thru the tubes that time was okay.
I cut the worn out filament and reinserted a fresh line of filament, came out with the same problem.
I don’t suspect anything broken within the AMS unit. But I know AMS 2 Pro tends to be a bit rough with the filaments.
I confirm nothing is wrong with the X1C itself as calibrations and extruder are working fine.

Anything I can do to fix this? Thanks

Any updates how to fix this?

That angle at the top of the ams is a bit sharp. You have maybe too much run there, and I think it’s a bit too long. The angle is really what I think the problem is.

You may want to route that PTFE under the arm of the ams tilt thing as it goes into the printer. As long as it doesn’t get pinched it should be ok. It looks like a tight angle there.

Also keep in mind to check the inner diameter of the tubes. If they’re worn then that combined with the angles/long run could cause issues. Always keep extra PTFE on hand.
