@dc42 looks like it is completely solved in this fix.

This is my temporary progress:

Works great, but no collet/tube interfaces yet. Hope someone finds it useful

@droftarts hi, sorry it took so long and many thanks for help.

First, answering your questions:

• same with beta2
• no, the pause is not in the middle of a particularly long move. My feeling is that this happens at every pause.
• I could not find any segmentation settings in OrcaSlicer (which I am using)
• from what i see in gcode, the slicer is using relative extrusion
• attaching the gcode of a cube 20x20x20 with 2 walls and some simple infil, that is used in the video
• youtube link at youtu be: c0CzmD-DGdg?si=Dh9AtsguJKMDB1lt to see the phenomenon in action. an overextrusion is clearly heard at 00:26

Here goes config.g:
