would be even less movement if mounted on one of the three rail carriages.

@Ulrich_Baer I wanted to separate the extruder from the frame. For lower vibrations and frame noise.

I like this. May have to try it on my Cartesian. You haven’t run into issues with tangles in the spool?

This will help reduce bowden tube drag a little bit, too.

@Greg_V I have a temporary solution, but the problem is not.

@Ryan_Carlyle Exactly. Also reduce the retraction distance.

@Jaroslav_Kovac As @Ulrich_Baer mentioned mounting the extruder on one of the moving rail carriages allows a shorter Bowden tube, with much more limited motion. (Less complex forces on the print head as you go faster.)

The motor moving that carriage faces more load. Not sure if that is an actual problem.

Vibration moves very well through metal, not so well through plastic, and not so well through dissimilar mediums (the plastic/metal boundary). So if the extruder is on a plastic mount and not in contact with the metal frame, that kills a lot of vibration.

Further, I am a fan of big plastic corners, good for forcing alignment, killing vibration, and stiff enough. Vibration on one rail … does not travel elsewhere.
