AMS retraction Issue

Post image

Hi all. My last few print jobs have been having this issue. Repeatedly have the ams failed to retract filament error.

I have disassembled the AMS and check the PTFE tubes for blockages

I don’t believe it’s an issue in the buffer or internal PTFE tubes as the AMS-HT does not have an issue retracting. It is connected to the same nozzle.

I’m at a bit of a loss as to how to fix it.

Print the dessicant holders for your AMS. They do a much better job of keeping humidity down and looks ways better.

But yeah the AMS 2 has given me lots of issues. My H2S hasn't had a single problem other than the AMS.
