I noticed that my prints with the AMS and some filaments caused the print to stop layer after layer due to the pressure the head receives.

 So I have designed this "clip" that is loose and leaves the sensor working margin so that when it reaches the stop it does not stop the printing and continues correctly.

 I've been using it for 2 months now and I haven't had any similar problems with the AMS.I hope it serves you as it serves me!
